The Modeling and Simulation of Ferrite Orthogonal Core Controllable Reactor Based on Matlab
The principle and structure of ferrite orthogonal core controllable reactor(FOC-CR) were discussed. The analysis of FOC-CR's magnetic equivalent circuit and basic equations was presented. Based on these, this paper establishes the relationship of FOC-CR's input voltage and flux through a odd polynomial assumption of MMF-Flux and gives a simulation model of FOC-CR in Matlab by using S-function.The modeling method is accessed from the result of both current wave and control characteristics of simulation model and experimental prototype.

The propriety of Edmund Burke's imagery was questioned around the noted colonial business enterprise of his brother
The famous 18th century British thinker and critic of the slave trade, Edmund Burke, has been detailed as a human being whose imagery may not be proper for the United kingdom Parliament in the wake of the Black Life Subject (BLM) protests.
Burke, a Dublin-born statesman who is credited for staying a important founding figure of conservatism, served as an MP in between 1766 and 1794. However, present day-working day British lawmakers have questioned whether his legacy ought to be cherished.
His identify was stated among "individuals and pursuits relevant to the British slave trade and the use of forced labour," as element of a evaluation of the parliament's artwork selection introduced in 2020 in response to the BLM protests. The contradiction amongst Burke's properly-documented anti-slavery posture and his title remaining on the record was highlighted on Wednesday by The Telegraph newspaper.
"It's unquestionably nonsense that Burke was a supporter of the slave trade. He was a critic of slavery from his to start with recorded sights. He discovered it abhorrent," Prof. Richard Bourke, a Burke expert and professor of political believed at King's Higher education Cambridge, explained to the daily.
Burke was additional to the list not for the reason that of what he did or reported but mainly because of his younger brother, Richard. A 2013 evaluate by English Heritage explained him as "a prosperous service provider and Caribbean land speculator," primarily based on a reserve published by present-day author William Burke, who could have been Edmund's kinsman.
The 2020 listing of supposedly questionable art lists 7 depictions of Edmund Burke in Parliament's selection, together with a photograph, a few prints, a portray and two sculptures.
His lifetime-measurement monument stands in St Stephen's Corridor inside the Palace of Westminster, even though the portrait is shown in the Member's Dining Room, in accordance to The Telegraph.

Store Table (ST)
Command title
Store Table
Description
The ST command stores the table — table data and table definition — to a tableBASE library.
COBOL syntax
MOVE 'ST' TO xxxx-COMMAND.
CALL 'TBLBASE' USING TB-PARM
 xxxx-COMMAND-AREA.
C syntax
memcpy( tbCommArea.tbCommand, "ST", 2 );
TBLBASE( &tbParm, &tbCommArea );
Parameters
None
Explanation
The ST command does not close the table. If an ST command addresses an Alternate Index, a new generation of the Data Table is actually stored instead; there is no effect on the Alternate Index itself.
Return value
ERROR 0018 occurs if there is insufficient space in the library.
ERROR 0019 occurs if the table is newly defined using DT or CN and a table with the same name is found in the library during the store.
Notes
tableBASE stores a new generation of a table before it deletes the oldest generation, if appropriate. Even if only one generation is to be kept, the new version of the table will be stored before the old space is released.
When stored, newly defined tables are automatically stored on the first library in the LIB-LIST (as set by the ML command) at the time of definition.
tableBASE does not permit a store of a newly defined table if the library contains a table with the same name. This prevents the inadvertent replacement of a previously defined table.
A table that has been read from a library will be stored into the library from which it was obtained, unless intentionally diverted by a DV or DW command.
Exceptions
None

Without immediate intervention, we could lose the Desert Arabian horse within the next generation
- The Desert Arabian horse is one of the oldest of breeds, developed by the Bedouin who bred them pure for thousands of years.
- The Desert Arabian horse provided the foundation stock to create almost all other light breeds of horse.
- Fewer than 8 percent of the 400,000 modern Arabian horses registered worldwide descend exclusively from the original Bedouin horse: these are the last Desert Arabian horses.
- New births of Desert Arabian horses have declined over 60 percent in the past decade; fewer than 800 fillies were born worldwide in 2010 – to mares that average 18 years of age.
Once lost, this precious genetic pool can never be restored. Only immediate intervention can save this breeding population for the next generation.
You can help.

The knapsack problem is $O(c\,n)$ where $c$ is the capacity of knapsack and $n$ is the number of items. Yet it's exponential because the size of the input is $\log(c)$.
However, why don't we emphasize length of input in other algorithms? To name one example, what would be the input size $n$ and worst case time complexity $T$ of the following input when using insertion sort:
111111111,101,11,10,1,0
Answer A: $n=6$, $T=O(n^2)$
Answer B: n = space(all_digits)+space(delimiters_between_numerics)
If B is correct, what is the time complexity $T$?
$\endgroup$
1
 - $\begingroup$ one way to visualize this. this is not taught/pointed out much in CS classes but theres a perfect proportional/inverse "tradeoff" between size of elements, number of elements, and total [memory] size of the input. for a fixed total memory size you can vary the # of elements to be less but then each one is larger and the total memory size is the same. $\endgroup$ – vzn Jun 29 '13 at 16:04

$\begingroup$
First, note that the input length of a Knapsack instance is $\Theta(n \cdot \log \max \{c,w_1,\dots,w_n\})$. Assuming the instance is "pruned", namely that all weights are at most $c$, this is $\Theta(n\log c)$.
In order to answer such questions, you need to fix
 - the machine model,
 - the cost model,
 - the set of valid inputs and
 - the algorithm.
You don't give the first three.
So your question is not well defined. In order store this particular set of numbers on a Turing machine tape, six symbols are indeed sufficient (one per number), and then the algorithm would run in time $O(1)$ on its only input. In order to get a general algorithm, however, you need to "properly" encode the numbers, namely B is the correct answer. I'll assume the latter.
Insertion sort has worst-case complexity $\Theta(n^2)$ in the RAM model with uniform cost model (elementary operations on naturals cost $1$), $n$ being the number of elements. In particular, it is independent of the size of the numbers. Since $n \leq |i|$, $i$ the input, you get an $O(|i|^2)$ time algorithm.
If you apply the logarithmic cost model (elementar operations on naturals have cost depending on their encoding length, cf. elementary school), you get time $\Theta(n^2 \cdot \log E)$ with $E = \log \max\{e_1, \dots, e_n\}$ the length of the largest input number, because the $\Theta(n^2)$ comparisons on the elements dominate the runtime. With similar reasoning as above, we note that the algorithm has runtime $O(|i|^2)$.
So as you can see, the qualitative result does not change when considering the input length for this kind of algorithms, so it is often glossed over. When analysing e.g. radix sort this is no longer valid, and you have to look more closely.

 - $\begingroup$ What does it mean by "$n \leq |i|$, $i$ the input"? Don't really get your $i$... $\endgroup$ – wlnirvana Jun 23 '13 at 1:25
 - $\begingroup$ @wlnirvana: The input $i$ is some encoding of $n$ numbers. As the encoding length of each number is at least one, $n \leq |i|$ (the length of the input). $\endgroup$ – Raphael Jun 23 '13 at 10:53
 - $\begingroup$ So once we take the encoding into consideration, it's not that accurate to say insertion sort is $O(n^2)$ because $n$ is not the input size. We'd better say it's $O(|i|^2)$. Am I correct on the point? $\endgroup$ – wlnirvana Jun 25 '13 at 1:37
 - $\begingroup$ @wlnirvana: Technically, that is correct. I argue in my answer why it does not make much of a difference (here). $\endgroup$ – Raphael Jun 25 '13 at 7:04
 - $\begingroup$ Got it. Thanks so much for your clarification. $\endgroup$ – wlnirvana Jun 27 '13 at 11:08

St Vincent's Catholic Primary School has been awarded the 'Dyslexia Aware Quality Mark' in recognition of the work it has done to make the school more dyslexia-friendly.
Project leader Miss Eileen Butler led a number of staff meetings to increase teachers' understanding of dyslexia and helped to provide practical ideas for teaching and learning along with assemblies, parents' workshops, meetings with the school's governors and visits to other schools.
A key feature of the work on dyslexia was the involvement of pupils, with a pupil learning committee set up to audit the provision for pupils and make recommendations.
Headteacher Anita Harrop said: "The input of pupils was crucial to this work. Gaining a better knowledge of the challenges faced by pupils with dyslexia allowed us to improve our provision and make all of our classrooms dyslexia-friendly. There was a whole school commitment to this process and staff are incredibly passionate about it."
A prime aim of the dyslexia award is to ensure teaching is multi-sensory; something that benefits all children, not just those with dyslexia. At St Vincent's, where the mission statement is 'let your light shine', the teaching is matched to a child's style of learning.
This year the school will again be taking part in 'No Pens Wednesday' on 4th October. This idea supports schools and settings with placing focus on the importance of speaking and listening. Within English lessons children will be taking part in oral storytelling and drama-based activities including hot seating and debating.
In maths, children will have the opportunity to make the subject as practical as possible with some children taking part in creating human bar charts, shape hunts and various other engaging practical ideas.

What is Locust?
Locust is an easy-to-use, distributed, user load testing tool. It is intended for load-testing web sites (or other systems) and figuring out how many concurrent users a system can handle.
The idea is that during a test, a swarm of locusts will attack your website. The behavior of each locust (or test user if you will) is defined by you and the swarming process is monitored from a web UI in real-time. This will help you battle test and identify bottlenecks in your code before letting real users in.
Locust is completely event-based, and therefore it's possible to support thousands of concurrent users on a single machine. In contrast to many other event-based apps it doesn't use callbacks. Instead it uses light-weight processes, through gevent. Each locust swarming your site is actually running inside its own process (or greenlet, to be correct). This allows you to write very expressive scenarios in Python without complicating your code with callbacks.
Features
 - Write user test scenarios in plain-old Python
No need for clunky UIs or bloated XML—just code as you normally would. Based on coroutines instead of callbacks, your code looks and behaves like normal, blocking Python code.
 - Distributed & Scalable - supports hundreds of thousands of users
Locust supports running load tests distributed over multiple machines. Being event-based, even one Locust node can handle thousands of users in a single process. Part of the reason behind this is that even if you simulate that many users, not all are actively hitting your system. Often, users are idle figuring out what to do next. Requests per second != number of users online.
 - Web-based UI
Locust has a neat HTML+JS user interface that shows relevant test details in real-time. And since the UI is web-based, it's cross-platform and easily extendable.
 - Can test any system
Even though Locust is web-oriented, it can be used to test almost any system. Just write a client for what ever you wish to test and swarm it with locusts! It's super easy!
 - Hackable
Locust is small and very hackable and we intend to keep it that way. All heavy-lifting of evented I/O and coroutines are delegated to gevent. The brittleness of alternative testing tools was the reason we created Locust.
Background
Locust was created because we were fed up with existing solutions. None of them are solving the right problem and to me, they are missing the point. We've tried both Apache JMeter and Tsung. Both tools are quite OK to use; we've used the former many times benchmarking stuff at work. JMeter comes with a UI, which you might think for a second is a good thing. But you soon realize it's a PITA to "code" your testing scenarios through some point-and-click interface. Secondly, JMeter is thread-bound. This means for every user you want to simulate, you need a separate thread. Needless to say, benchmarking thousands of users on a single machine just isn't feasible.
Tsung, on the other hand, does not have these thread issues as it's written in Erlang. It can make use of the light-weight processes offered by BEAM itself and happily scale up. But when it comes to defining the test scenarios, Tsung is as limited as JMeter. It offers an XML-based DSL to define how a user should behave when testing. I guess you can imagine the horror of "coding" this. Displaying any sorts of graphs or reports when completed requires you to post-process the log files generated from the test. Only then can you get an understanding of how the test went.
Anyway, we've tried to address these issues when creating Locust. Hopefully none of the above pain points should exist.
I guess you could say we're really just trying to scratch our own itch here. We hope others will find it as useful as we do.

Cultural Competence Toolkit – Involving Volunteers from Culturally and Linguistically Diverse Backgrounds
Cultural Competence aims to foster constructive interactions between members of different cultures. The following is a widely used definition: "Cultural competence is a set of congruent behaviors, attitudes and policies that come together in a system, agency, or among professionals and enable that system, agency or those professionals to work effectively in cross cultural situations" (Cross et al, 1989). The word "culture" implies an integrated pattern of human behavior and the word "competence" implies having the capacity to function effectively. Cultural competence should be viewed as an on-going process. Through this process, individuals develop awareness and knowledge about the value that diversity can bring to an organization and a community. Cultural competence goes beyond "culture as ethnicity" to discover the complexities of individual cultural identities (Cross et al, 1989). A culturally competent organization: Values diversity and incorporates at all levels the importance of culture.
Conducts an assessment of cross-cultural relations.
Is vigilant towards and manages the dynamics of cultural difference.
Expands its cultural knowledge.
Adapts its services to meet the culturally-unique needs of individuals served
(Cross et al, 1989).

Case Model predictive control of phenolic resin production
Cybernetica delivers Model Predictive Control (MPC) and Endpoint Prediction of phenolic resin manufacturing processes based on Cybernetica CENIT. This system is currently controlling numerous resole phenolic resin reactors in North America, Oceania and Europe.
MPC is used for control of reactor temperature and reaction rates, by controlling cooling and heating utilities and metering (dosing) rates of formaldehyde, phenol and catalysts.
The main benefits of using this technology compared to conventional control are:
- Stable, accurate and consistent control of reactor temperature and reaction rates.
- Shorter and less variations in batch cycle times.
- Improved consistency of product quality parameters.
- Improved safety.
- Endpoint (cut-off) determination using kinetic model.
- Less need to take grab samples from the reactor.
- Less operator intervention – higher degree of automation.
The essential features of the Cybernetica CENIT, which enable these benefits, are:
- Online parameter estimation – the model adapts online to changes in process conditions.
- Predictive control – the future process performance is continuously predicted and optimized.
The mechanistic process model utilized within Cybernetica CENIT is adapted to each specific process unit. Reactor design data are acquired from the customer. Other model parameters are estimated off-line from logged process data using Cybernetica ModelFit.
Model of phenolic resin reactor
- Kinetics and thermodynamics:
- Methylolation reactions
- Condensation reactions
- Formaldehyde, hemiformal and ionization equilibria
- Cooling and heating utilities:
- Coil cooling is dependent on estimated heat transfer coefficients and on the liquid level in the reactor.
- Reflux condenser and vacuum system.
- Steam heating.
- Feed systems for raw materials
Model predictive control (MPC)
MPC enables safe and accurate control of reaction rate and reactor temperature by controlling:
- Coil cooling, jacket cooling and steam heating.
- Vacuum and condenser cooling during polymerization and distillation.
- Metering (dosing) rates of formaldehyde, phenol and catalysts.
MPC allows fast response to step changes in temperature setpoints, which will reduce batch cycle times. Predictive temperature control is illustrated in the video below.
Temperature control during initial exotherm and step change of temperature setpoint. The predicted cooling water flow and reactor temperature, during the 15 minutes prediction horizon, are shown to the right of the vertical line indicating present time. A 15 minutes history is shown to the left.
Safe and efficient metering of raw materials
The metering (dosing) rates of raw materials are safely controlled such that the predicted reaction heat does not exceed the currently available cooling capacity, and such that other constraints (e.g., maximum reactor temperature rate of change) are not violated. The available cooling capacity may typically vary significantly during a batch due to
- changes in cooling water temperatures,
- changes in available cooling water flow rates,
- varying heat transfer coefficients,
- and varying liquid level in the reactor.
All these changes are immediately compensated for in the calculation of raw material metering rates.
Optimal metering rates of formaldehyde will typically vary greatly from start to end of the metering phase, and there is a lot to gain in batch cycle time, in addition to the safer operation, by utilizing MPC.
Cybernetica CENIT ensures that the polymerization reactions are safely controlled in spite of uncertain and rapidly changing cooling capacity. The adaptive model will also compensate for deviations between the reaction heat predicted by the model and the actual reaction heat observed from reactor measurements.
In addition to the inherent safety associated with the model predictive control methodology and the online model adaptation, CENIT includes functionality for fault detection and diagnosis.
Automatic endpoint determination
Endpoint determination of "shortly condensed" resins of low viscosity development are often accomplished by manually analysing grab samples from the reactor, e.g. for free phenol content or based on cloud point determination. This is undesirable when full automation is aimed for.
The degree of polymerization, as calculated from the kinetic model, is successfully being used for endpoint determination of shortly condensed resins, resulting in improved consistency of product quality parameters.
Operator graphic for polymerization monitoring
The system includes an operator graphic display where temperature, reaction heat and cooling capacity profiles are compared to those of a previously manufactured "golden batch". The "golden batch" profile is "time warped" to make the two batches comparable even though the reaction rates progress differently with time. The purpose of the polymerization monitoring system is to:
- Monitor the development of the current batch, as compared to the golden batch.
- Detect deviations between the current batch and the golden batch.
- Predict the future progress of the current batch, including the endpoints.
A snapshot of the graphic display is shown in the figure below. The history is displayed to the left of the vertical line indicating present time, and the future predictions are shown to the right. The graphic display is used to monitor the current batch (solid lines) by comparing with a previously manufactured "golden batch" (dashed lines). The reaction heat and the maximum cooling capacity are shown in the upper graph; the reactor temperature and the temperature setpoint are shown in the middle graph. A selection of user defined variables can be shown in the lower graph.
Cybernetica CENIT applications typically runs on a dedicated application station (Windows server). It communicates with a DCS system via the Open Platform Communications (OPC) protocol.
Cybernetica employees have extensive experience in industrial implementation and commissioning of advanced process control (APC) applications.
Integration with sequential batch control system
Cybernetica CENIT can run independently of a batch control system, with the operator providing essential inputs such as temperature setpoint profiles and raw material amounts. CENIT can, however, preferably be integrated with a sequential batch control system, in which case the batch control system will provide a number of input parameters to CENIT, dependent on the current stage in the batch process and on the specific resin grade being manufactured.
Cybernetica's maintenance programme ensures that all applications perform at their best at all times. Cybernetica rapidly responds to customer requests. Cybernetica CENIT has built-in functionality for reproduction and diagnosis of current or past process situations, facilitating efficient analyses of issues reported by the customer.
The most common and important issues are reported directly to the operators, enabling the operators to act when necessary.


TY - CPAPER TI - Techniques To Increase Yield Pillar Residual Strength AU - Dolinar, Dennis R. PB - International Conference on Ground Control in Mining AB - The U.S. Bureau of Mines has modeled yield pillars to determine the effects of reinforcement techniques on pillar performance. Model pillars with width-to-height (w/h) ratios ranging from one to four were reinforced using advanced lateral support systems. To evaluate reinforcement and pillar performance, the model pillars were strained up to 18.6 pct in compression. The results show that the reinforcement had a significant effect on the postfailure characteristics of the pillar but had only a small effect on it's maximum failure strength. Pillar residual strengths increased up to 10 times, while the energy capacity increased by a factor of three depending on the reinforcement method. At maximum deformation, the residual strengths of several types of reinforced specimens exceeded the maximum compressive strength up to 2.5 times and resulted in an increasing positive postfailure stiffness. Test results, data analysis, and application of the results to underground mining are discussed. PY - 1993 ER -


6 Ways Seniors Benefit from Following Daily Routines
By 9 am on
Tips Seniors Benefit from Following Daily Routines in Tucson, AZ
Many people envision their retirement years as a time of rest and relaxation. However, when seniors don't follow regular routines, it can take a toll on their health. Here are six benefits of maintaining a daily routine in the senior years.
1. Lowers Stress
Aging can be stressful, and many seniors are worried about everything from their weekly budgets to their nutrition intake. Stress is compounded when a senior has a health condition, whether it's a cognitive disorder such as dementia or a mobility-restricting issue such as arthritis. When seniors follow consistent daily routines, they no longer have to worry about when they're going to eat lunch or what time they should go to bed. With time, the structure of each day will become embedded in muscle memory, keeping them going even when they feel anxious.
2. Provides Greater Feelings of Security
For anxiety-prone seniors, feelings of safety and security may seem out of reach. When they follow regular schedules, their days are more predictable. Predictability can be a great source of comfort for seniors, especially those facing disorienting transitions, such as moving out of their homes or being diagnosed with Alzheimer's.
3. Makes It Easier to Maintain Personal Hygiene
Mobility limitations such as diminished motor coordination can make it difficult to brush teeth or hair. Cognitive, emotional, and mental conditions such as dementia and depression can deplete the energy needed to perform basic hygiene tasks. When seniors have structure in their lives, they're more likely to practice good hygiene. Being able to follow personal care schedules may boost their self-esteem and brighten their outlook.
4. Boosts Cognitive Health
For seniors with dementia, schedules are especially crucial. Dementia doesn't have a significant impact on the part of the brain that stores repetitive actions, which means seniors with dementia may have an easier time remembering a daily schedule than the name of a new acquaintance or the time of their next doctor's appointment. The familiarity of these repetitive actions can provide relief from dementia-related disorientation. Structured schedules can also help seniors manage important daily tasks such as taking medication.
5. Makes Changes Easier to Notice
When seniors follow schedules, it's easier to identify when elements of their daily lives go awry. An aging adult who does laundry every Monday will probably notice when the weekly load of laundry becomes too heavy to carry. Not all seniors are willing to ask for help when they need it, but they're more likely to ask if they spot problems on their own.
6. Promotes Better Sleep
Getting eight hours of sleep every night is important at any age, but the restorative powers of slumber are particularly essential for senior health. When seniors follow schedules, they're more likely to go to bed at the same time every night, which makes it easier to fall asleep and enhances overall sleep quality.

This talk will introduce the concept of developmental readiness for leadership, and in the context of higher education, discuss its relevance in examining the effects of leadership education interventions in building leadership capacity in students. Specifically, it will focus on three aspects of student leadership development: leadership self-efficacy ("ready"), motivation to lead ("willing"), and leadership skill ("able"). Recent research suggests that students at various levels of readiness display disparate gains in each of these three areas within the same interventions.

Dr. Kent Palmer recently presented his research on developing a Cloud-based Cyberlearning Environment for Introductory Computing Programming Education at the International Conference on Advanced Learning Technologies. Dr. Palmer's research focused on using the Google App Engine to develop cyber learning objects that would be hosted in the cloud. Apps were developed for teaching both Python and Java programming. This research was done in collaboration with researchers at Southern Polytechnic State University, University of Cincinnati, and Albany State University.
The cloud based learning objects allow students to engage in class activities from nearly any location and at anytime. Since the objects are hosted in the cloud and ran on remote severs, students are able to work on nearly any device that supports a web connection. So a student can engage in class activities from their smart phone, tablet, laptop, or desktop computer. As long as they have a web browser they do not need to install additional software. Normally to learn programming students need to install compilers to compile their code and an editor to write their software. On personal computers this sometimes created a difficulty for new students that did not know how to install and configure the software and may not have been possible on mobile devices such as tablets and phones. The learning objects developed by these researchers overcame these difficulties and allowed students to focus on learning how to program.

Working with Workspaces
To store the results of your investigations, dotMemory uses workspaces. A workspace, as the name suggests, saves everything you see on the screen: all open analyses including all collected snapshots and analyses paths. In other words, it saves the current state of dotMemory.
After the profiling session ends, the workspace is saved automatically to a default location (you may change it anytime). As workspace files can be very large, we recommend that you automate workspace files cleanup by setting up workspace auto-deletion.
In case you want to copy a workspace to another computer, you can save it as a single archive.
In this section:

- Importing and Exporting Workspaces
- Importing Process Dumps
- Adding Annotations to Workspaces

Rookidee, Corvisquire, Corviknight – Origin of Species
As with every region before it, Galar has a common bird Pokémon which is found on many routes. This evolutionary line does have a distinctive British theme which makes it well-suited as the design for the region.
Rookiee, the Tiny Bird Pokémon, has a somewhat unique typing of just Flying. Aside from Tornadus, no other Pokémon has had flying as its only type. Generally the common bird Pokémon of each region starts with the type pairing of Normal and Flying.
Its name, a combination of Rook and Chickadee, suggests it is based on the chickadee bird. Outside of North America it may also be known as a tit (not a link to anything nsfw) or a titmouse. From that genus it may in particular be based on the European blue tit, which live pretty much everywhere in Great Britain. Both share the same blue coloring, the yellow belly, and the black marks around its eyes.
The former part of its name, the rook, could be a reference to a different type of bird. A rook is a large bird in the raven family. It is also the weakest in the line, so 'rookie' plays in nicely, too. Finally, the rook is a castle-shaped chess piece which ties into the medieval theme found in its evolutions' names.
It will bravely challenge any opponent, no matter how powerful. This Pokémon benefits from every battle—even a defeat increases its strength a bit.
The Pokédex suggests it is an acrobatic Pokémon and fairly brave. Though the chickadee is a small bird, there have been observations of its intelligence in gathering food. At a time when milk was delivered, they were able to break the foil seal and drink the milk—Miltank farmers beware.
Corvisquire is fully based on a raven, with its name being a combination of corvidae and squire. Corvidae is the family name for birds which include crows, ravens, and rooks.
In particular it may be based around the hooded crow, as both share many of the same coloration patterns. It is also known as the grey crow in some sregions.
Smart enough to use tools in battle, these Pokémon have been seen picking up rocks and flinging them or using ropes to wrap up enemies.
The lessons of many harsh battles have taught it how to accurately judge an opponent's strength.
The Pokédex makes reference to its intelligence, which is a trait that distinguishes ravens from many other animals. Corvids have shown an ability to learn how to create and use simple tools to accomplish tasks. To get insects burrowed into trees, they can use sticks to poke the insects and lure them out. They have also been observed placing stones into a body of water to raise the water level through volume displacement.
The new caledonian crows have shown the most success in developing tools, which may have served as a secondary influence for this Pokémon.
The latter half of the Pokémon's name is a reference to knighthood in England. Knighthood was given to those, often young nobles, who proved their skill in battle. The career growth of a knight became fairly regular.
At an early age they served the role of a page, assisting those in the castle and knights with basic tasks of maintenance and cleaning. At the age of fifteen they became a squire, where they trained in combat and wore basic armor alongside their duties of aiding knights.
They could be knighted after winning a decisive victory, completing a quest, or other reasons. Knights were given the new title as part of a ceremony by royalty or a noble.
Corviknight is the Raven Pokémon. While it may at first glance appear to be a Dark-type, due to its black color scheme and bright red eyes, it actually has Steel as its secondary typing.
Aren't ravens and crows basically the same? Not at all. The Audubon Society has put together a useful guide to the differences. Ravens are often much larger, organize in pairs instead of larger murders (murders here meaning a collection of crows). Ravens will make a low-pitched croak instead of a caw.
Similarly, Murkrow and Corviknight are also different. Looking at the two Pokémon side-by-side, you can very quickly see that there are size differences, and Corviknight looks more intimidating.
Looking closer at its design, it seems to resemble a knight in its overall design. As we can see in the screenshot below, its body seems to be slightly metallic, with its eyes peaking outside of its helmet-like head. This knight aesthetic could explain its Steel typing.
The association between knights and ravens is not unheard of in the folklore of England and neighboring countries. It makes sense, as knights were a big part of medieval culture, and ravens are also very common birds in that region. Bulbapedia suggests its design is based on the western jackdaw. It also suggests an allusion to the Black Knight, although it lacks the evil connotations.
Ravens are also a part of English folklore. There are six ravens kept in the Tower of London. A legend suggests that the tower and the nation would fall if the ravens left. This could be pretty interesting to dive into further, if there were legendary Pokémon based on ravens which lived in a tall tower.
While this doesn't come up in the game, as Corviknight is not a legendary Pokémon, this legend is directly referenced by one of the trainers on Route 10.
Another interesting piece of folklore, from Danish culture, is the valravn. These are mythical ravens which come into their form through ravens who eat the body of the dead on the battlefield. If a valravn eats the whole heart of a child, they will have the power to transform into the form of a knight. It's also said that if they eat the heart of a king, they will gain "human knowledge", act as a bad influence, and gain superhuman strength.
This Pokémon reigns supreme in the skies of the Galar region. The black luster of its steel body could drive terror into the heart of any foe.
So this could be the Pokémon equivalent of a valravn, with its half-bird, half-knight form. Valravn are also said to be able to transform into wolves, but that seems to be an alternative interpretation.
Vilderavn artwork from Pathfinder
As a quick aside, Valravn also appear in the tabletop RPG Pathfinder under the name Vilderavn. They appear in the fifth bestiary as a type of monster that players could encounter. Looking at the Pathfinder art for the creature, you can see that there's definitely a resemblance.
There was a Hungarian king in the 1400s, Matthias Corvinus, who is referred to as the "raven king". However, that is probably unrelated to Corviknight.
Corviknight plays a key role in the Galarian economy by allowing one to fast travel to various cities and locations in the region through a flying taxi. However this seems to be a specific skill that they need to be trained to learn, as one's own Corviknight is unable to do that.
Gigantamax Corviknight
In Corviknight's Gigantamax form, its wingspan grows dramatically and it starts to glow a reddish hue. Its glowing feathers appear to be detachable and used for attacks similar to throwing daggers or stars.
Imbued with Gigantamax energy, its wings can whip up winds more forceful than any a hurricane could muster. The gusts blow everything away.
The eight feathers on its back are called blade birds, and they can launch off its body to attack foes independently.
Ravens are a common bird in Great Britain, part of the kingdom's history, mythos, and environment. As such it is the perfect basis for the region's primary bird Pokémon.

hot money business definition
Funds that are controlled by investors who seek high short-term yields when the funds are likely to be reinvested somewhere else at any time. Some financial institutions attract hot money by offering above-average yields on certificates of deposit. However, if the rate is lowered, the funds are likely to be lost to another institution or investment.Case Study
Although an improbable target for currency speculators, tiny Iceland (population approximately 300,000) gained fame as a world depository for hot money shortly after the country lifted currency exchange controls in the late 1990s. Funds seeking the krona's high interest rates flooded into the island country from around the world, much of it representing borrowed money obtained in low-interest Japan. The inflows helped produce a booming economy with a strong currency, soaring stock market, and skyrocketing housing prices. The economic boom was accompanied by inflation, causing the central bank to raise interest rates to 11.5% by mid-2006. The increase in interest rates also resulted from the government's concern that hot money would begin flowing back out of Iceland as interest rates started rising in Europe, Japan, and the United States. A rapid outflow of hot money would depress the country's currency, increase the cost of imported goods, and cause a downward spiral in asset values.

Following months of discussion, 250 delegates have, at the base of Uluru, made a historic statement for the future of Indigenous affairs in Australia. In the milestone year of 2017 – 50 years after the 1967 Referendum – the First Nations National Constitutional Convention has culminated in calls for Makarrata, the coming together after a struggle.
The delegates from across the country expressed their support for enshrining the voice of the First Nations in the Constitution, and for the establishment of a treaty between governments and the First Nations. Prominent themes that emerged from the talks are the rejection of simple 'tokenistic' constitutional acknowledgement in favour of meaningful structural reform, as well as a focus on supporting the continued sovereignty of Indigenous peoples and on 'truth-telling' about Indigenous history.
Met with a standing ovation from those involved, the 'Uluru Statement from the Heart' marks a monumental step for the future direction of Indigenous affairs in Australia to address the structural problems communities face and to empower these communities for an improved future.

Diffusion and the formation of vorticity staircases in randomly strained two-dimensional vortices

 Abstract
 The spreading and diffusion of two-dimensional vortices subject to weak externalrandom strain fields is examined. The response to such a field of given angularfrequency depends on the profile of the vortex and can be calculated numerically.An effective diffusivity can be determined as a function of radius and may beused to evolve the profile over a long time scale, using a diffusion equation thatis both nonlinear and non-local. This equation, containing an additional smoothingparameter, is simulated starting with a Gaussian vortex. Fine scale steps in thevorticity profile develop at the periphery of the vortex and these form a vorticitystaircase. The effective diffusivity is high in the steps where the vorticity gradient islow: between the steps are barriers characterized by low effective diffusivity and highvorticity gradient. The steps then merge before the vorticity is finally swept out andthis leaves a vortex with a compact core and a sharp edge. There is also an increasein the effective diffusion within an encircling surf zone.In order to understand the properties of the evolution of the Gaussian vortex, anasymptotic model first proposed by Balmforth, Llewellyn Smith & Young (J. FluidMech., vol. 426, 2001, p. 95) is employed. The model is based on a vorticity distributionthat consists of a compact vortex core surrounded by a skirt of relatively weakvorticity. Again simulations show the formation of fine scale vorticity steps withinthe skirt, followed by merger. The diffusion equation we develop has a tendency togenerate vorticity steps on arbitrarily fine scales; these are limited in our numericalsimulations by smoothing the effective diffusivity over small spatial scales.

Murraywood Construction have cut their CO2 emissions created by site operated plant by 93% over the past six months.
We made a conscious effort in April of this year to switch from using fossil fuels to HVO fuel in our site operated plant as part of our ongoing mission to become net carbon zero.
HVO (Hydrotreated Vegetable Oil) is a fossil fuel free alternative to mineral diesel and therefore results in a 90% reduction in greenhouse gas emissions.
As a result of this change, in the six months between April to September we created just 15,120kg of CO2.
To put this into perspective, had we used diesel instead we would have created 207,742kg of harmful CO2.
Although we know we still have work to do before we can say we're net carbon zero and achieved our goal, we're incredibly proud that this one small change for us has made a massive impact on our carbon footprint.

Polonia, this jester is pleased as punch to tell you, that you can now celebrate Columbus Day as well as Pulaski Day, so get out there in September with the Italians and celebrate with pride our newest Pole, Christopher Columbus! Portuguese historian Manuel Rosa has spent the better part of two decades studying the Columbus myth and has now reached a new conclusion, that everything we thought we knew about Columbus was wrong.
First book up on the background articles:
- AOLBook: Columbus Was Son of Polish King
- London Daily Mail: Christopher Columbowicz
Apparently Columbus's grandfather was the founder of the Jagiellonian Line of Polish Kings. And his father was Wladislaw III. Wladislaw III was thought to have died at the Battle of Varna in 1444. Luckily for America he survived, found absolution in Palestine for his wrongs, and settled in Portugal, where the Portuguese King gave him land on the island of Madeira, and he married Portuguese aristocracy and had two sons (one of which was Columbus).
Now this story makes sense of why Columbus had access to no less than four royal lines who he could approach and propose such a venture of discovering a new path to the Orient (uh America, ummm, the Caribbean Islands). A Book is coming and National Geographic is also interested in the story. Manuel Rosa is now seeking access to DNA to prove his theory. In the mean time, lets see some Polish flags next September at the Columbus Day Holiday Parades and reclaim our prodigal son from the Italians. This will be a nice entre into October (Polish History Month, Pulaski Day celebrations) giving Polonia two months of pride. Also drink some Madiera wines. It appears we can thank our Polish son for this wine appearing in the Americas — a nice red wine. This also adds to the credibility that Columbus was born on the Island of Madiera (a Portuguese territory at the time) and not in Genoa.

Mar. 6, 2013 Boys are right-handed, girls are left... Well at least this is true for sugar gliders (Petaurus breviceps) and grey short-tailed opossums (Monodelphis domestica), according to an article in BioMed Central's open access journal BMC Evolutionary Biology that shows that handedness in marsupials is dependent on gender. This preference of one hand over another has developed despite the absence of a corpus collosum, the part of the brain which in placental mammals allows one half of the brain to communicate with the other.
Many animals show a distinct preference for using one hand/paw/hoof over another. This is often related to posture – an animal is more likely to show manual laterality if it is upright, related to the difficulty of the task, more complex tasks show a handed preference, or even with age. As an example of all three: crawling human babies show less hand preference than toddlers.
Some species also show a distinct sex effect in handedness but among non-marsupial mammals this tendency is for left-handed males and right-handed females. In contrast researchers from St Petersburg State University show that male quadruped marsupials, such as who walk on all fours, tend to be right-handed while the females are left-handed, especially as tasks became more difficult.
Dr Yegor Malashichev from Saint Petersburg State University who led this study explained why they think this has evolved, "Marsupials do not have a corpus callosum – which connects the two halves of the mammalian brain together. Reversed sex related handedness is an indication of how the marsupial brain has developed different ways of the two halves of the brain communicating in the absence of the corpus callosum."

Decision Code: 29 COM 7B.62


I would point out keeping people in prison for a lifetime is very expensive. If an offender who will never be released chooses to die his choice saves the taxpayer a great deal of money even if this choice includes expensive counselling. Secondly and I believe more importantly I would question whether these safeguards really need to include expensive counselling. For I would suggest all that is needed for a decision to be autonomous is that it is wholehearted and un-ambivalent. I would suggest if an offender expresses a constant un-ambivalent desire to die over a period of a few months, then his decision is an autonomous one and as such ought to be respected. Our objector might respond that my suggestion means a severally depressed offender might choose to die. In reply I would simply point out being depressed may well be the natural state of affairs for such an offender and suggest his depression does not preclude him from making an autonomous decision to die.
I have argued the reason why we should allow such offenders the right to die is based on their autonomy. I further argued that the basis of autonomy is seeing others as basically the same sort of persons as ourselves. However our objector might mount a third objection. He might argue if we allow these offenders the right to die then we are sending them a message that even at this basic level they are not the same sort of persons as ourselves. He might point out if we saw someone about to jump from a high building we would try and talk him down rather than simply pass by or tell him it's his choice whether to jump or not. Indeed our objector might accuse us of double standards. The same objection might also be made if we allow terminally ill patients to choose when to die. I would reject his objection by arguing the difference in our attitudes is due to a difference in circumstances rather than a supposed difference in persons. An offender may be depressed and as I have suggested this depression may be both natural and normal considering his circumstances. His depression may be natural because his ongoing circumstances will not significantly change. Someone about to jump from a building may also be depressed but his depression may not be natural and certainly need not be ongoing as his circumstances might change. These different circumstances mean the offender's decision, subject to certain safeguards, is an autonomous one whilst the decision of the man about to jump from a high building may not be. An autonomous decision is a constant un-ambivalent decision. If we permit an offender to die we can be fairly certain his decision is an autonomous one because the prison authorities would require that he had expressed an un-ambivalent desire to die over a period of some months. The same requirement cannot be applied to someone about to commit suicide by jumping from a high building.
Our objector might now point out, offenders do not have a handy means of suicide readily available, and that if my conclusion is accepted the means of suicide would have to be approved of and brought into prison by the relevant authorities under strictly controlled conditions. I accept the objectors point. He might then use this point to raise a fourth objection to my conclusion. He might argue accepting my conclusion reintroduces capital punishment by the back door and once again accuse me of double standards due to my stated opposition to capital punishment. In reply I would reject his argument by firstly pointing out capital punishment is imposed and not simply optional. Secondly I am not proposing that the prison authorities kill these offenders even with the offender's approval. I am proposing that the prison authorities make the means of suicide available to such offenders in controlled circumstances. These circumstances might be the much the same as those in the Dignitas clinic in Geneva. The person committing suicide in this clinic takes an anti sickness drug followed half an hour later by the overdose that kills him. In similar circumstances the offender would not have the drugs administered to him but would have them provided for him to take them himself. The fact that these drugs would be self administered would be an important additional safeguard of the offender' autonomy, for often someone may believe he should take some course of action but when he tries to implement this action finds he cannot. For as Frankfurt points out someone's decision only show what he intends to will and that when he attempts implement his decision he might be surprised to find out his decision does not in practice represent his will (3). In the above circumstances it would be hard to characterise the assisted suicide of an offender as capital punishment. Recently in Belgium Frank Van Den Bleeken who is serving a life sentence for rape and murder has been allowed by a court to undergo euthanasia, see bioedge. However I agree with Frankfurt that someone's decision only show what he intends to will and in practice his decision may not always truly represent his will. For this reason whilst I believe offenders should have the right to commit suicide I would be doubtful whether this right should extend to euthanasia.
In conclusion it appears all my imagined objector's objections remain unconvincing. Finally I wish to consider an additional reason to that of the offender's limited autonomy to support my position. Harrosh suggests if a prisoner on death row chooses a method of execution involving greater suffering that his choice can be a form of atonement. I would extend Harrosh's suggestion further by suggesting if an offender chooses to die this might also be a form of atonement. In practice I don't believe the need for atonement would be a major factor in decision making of most these offenders' decisions to die. Rather it would be a desire to escape from life long imprisonment. None the less I believe it might be a factor in some such cases. Such atonement should be accepted not only because it is an expression of an offender's limited autonomy but also because the acceptance of responsibility by the offender for his offences is something which may benefit the victim or victim's relatives.

I was solving a question from the Regional Math Olympiad (RMO) 2014.
Find all positive real numbers $x,y,z$ such that
Here's my solution:
These expressions are cyclic. Therefore all solution sets must be unordered. This implies that $x=y=z$.
Thus, $x=2014$ and the solution is
$$x=2014\quad y=2014\quad z=2014$$
Here's the official solution:
Adding the three equations, we get $$\frac1x+\frac1y+\frac1z=\frac3{2014}$$
We can also write them as $$2xz-2yz+1=\frac z{2014},\quad2xy-2xz+1=\frac x{2014},\quad2yz-2xy+1=\frac y{2014}$$
Adding these, we get $$x+y+z=3\times2014$$
Therefore, $$\left(\frac1x+\frac1y+\frac1z\right)(x+y+z)=9$$
Using $\text{AM-GM}$ inequality, we therefore obtain $$9=\left(\frac1x+\frac1y+\frac1z\right)(x+y+z)\ge9\times(xyz)^{\frac13}\left({1\over xyz}\right)^{\frac13}=9$$
Hence equality holds and we conclude that $x=y=z$.
Thus we conclude $$x=2014\quad y=2014\quad z=2014$$
What I wonder is if there is something wrong with my approach. If yes, what is it? If no, then why is the official solution so long winded?

 $\begingroup$ What exactly is a "solution set" and what does it mean for a solution set to be unordered? If a "solution set" is a set, then of course it is "unordered" because all sets are. Why would this imply that $x=y=z$? $\endgroup$ – littleO May 14 '18 at 10:48
 - 17
 $\begingroup$ Any solution of $(x-2y)(y-2x)=0$, if permuted, results in another solution. That doesn't mean we can conclude that $x=y$. It just means our solution set is symmetric across the line $x=y$. $\endgroup$ – G Tony Jacobs May 14 '18 at 10:57

Consider the system of equations
$xy + z = 1, \quad yz + x = 1, \quad zx + y = 1$
These equations are related by cyclic permutations of $(x,y,z)$, but they are satisified by $(1,1,0)$ (and its cyclic permutations) when $x$, $y$ and $z$ are not all equal.
There are also solutions where $x=y=z=\frac{\pm \sqrt{5}-1}{2}$, but these are not the only solutions.
 - $\begingroup$ Ah. Of course. I didn't realize that. However, the question asks for positive reals. Could you provide an example where the solution set is wholly positive and unordered, but where the unknowns aren't equal? $\endgroup$ – DynamoBlaze May 14 '18 at 11:04
 - 15
 $\begingroup$ How about the same left-hand sides, but they're all equal to $3$? Then every permutation of $(1,1,2)$ works. $\endgroup$ – G Tony Jacobs May 14 '18 at 11:07
As Mohammad Riazi-Kermani and gandalf61 show, you cannot conclude $x=y=z$ simply from the cyclic invariance of the system of equations. However, in this case you can make a simple argument that starts with an observation based on cyclic invariance, namely that you may as well assume $x\ge y,z$ (i.e., cycle through $(x,y,z)$, $(y,z,x)$ and $(z,x,y)$ and pick the one that starts with the largest of the three numbers).
If $x\ge y,z$, then $2x-2y\ge0$ while $2z-2x\le0$, so that
$${1\over2014}=2x-2y+{1\over z}\ge{1\over z}\implies z\ge2014$$
$${1\over2014}=2z-2x+{1\over y}\le{1\over y}\implies 2014\ge y$$
so we now have $x\ge z\ge 2014\ge y$. But this now tells us $2y-2z\le0$, so that
$${1\over2014}=2y-2z+{1\over x}\le{1\over x}\implies2014\ge x$$
so we now have $2014\ge x\ge z\ge 2014\ge y$, from which we see $x=z=2014\ge y$. The final equality, $2014=y$, comes by sustituting $x=z=2014$ into any of the three equations.
Note, the implication ${1\over2014}\ge{1\over z}\implies z\ge2014$ requires the assumption $z\gt0$.
The equations being cyclic does not necessarily mean the variables are equal.
For example $$ x+y+z=6\\x^2+y^2+z^2=14\\x^3+y^3+z^3=36$$ Solutions are not equal. $$x=1, y=2,z=3$$ is one solutions set.
 - $\begingroup$ This isn't cyclic. Cyclic would be $3x^3+2y^2+z=11,3y^3+2z^2+x=11,3z^3+2x^2+y=11$. What I mean by cyclic is that you can just shift the places of the variables one to the left or one to the right to get another one of the given equations. $\endgroup$ – DynamoBlaze May 14 '18 at 13:46
 - $\begingroup$ _USER_ Thanks for the comment. That is quite different from what I was thinking. $\endgroup$ – Mohammad Riazi-Kermani May 14 '18 at 14:09
 - 1
 $\begingroup$ _USER_ That's not the standard definition of "cyclic". $\endgroup$ – Acccumulation May 14 '18 at 17:40
The general cyclic system is $$ f(x,y,z)=f(y,z,x)=f(z,x,y)=0$$ with some function $f$. There is not the slightest reason to assume that $f(42,\pi,e)\ne 0$.
First, your use of the word "cyclic" isn't quite consistent with its usual meaning.
Second, a counterexample:
yz+x = 0
zx+y = 0
(1,1,-1) satisfies these equations.

Pittsburgh is located in Allegheny County and is the largest inland port in the United States. George Washington was sent to the Pittsburgh region in 1753 and reported that the area was well suited for a fort. Fort Pitt was later built and the town was founded in 1764.
Pittsburgh was the place where many of America's heavy industries grew most strongly during the 19th century, such as steel, aluminum, and plate glass. Unfortunately, the city was so filled with smoke that it became known as "Smoky City." A smoke control program was started in 1941 and since the 1950s, residents of Pittsburgh have enjoyed much cleaner air. The industrial base has shifted from heavy industry to a greater emphasis on high tech and education.
Pittsburgh is situated at the confluence of the Allegheny River and the Monongahela River, which then form the Ohio River.
Pittsburgh is part of the Pittsburgh, Pennsylvania metro area.

Letters from the SAL: Urban Tree Canopy Assessment - Rockville, MD:
The video below presents the results of the urban tree canopy (UTC) assessment we just completed for Rockville, MD. High resolution land cover is the basis for the UTC assessment. Rockville is covered by both leaf-on color infrared imagery and LiDAR data, but mapping land cover proved to considerably more challenging than we expected. Some filtering was performed on the LiDAR data, resulting in a very inconsistent first return dataset (we did not have access to the point cloud). By taking a data fusion approch, combining the LiDAR and imagery in Definiens we were able to get around this, but it was not easy. I discuss these issues a bit in the video, but hope to cover the process in more detail in a future post. Imagery was prepped using ERDAS IMAGINE. LiDAR data was prepped using QT Modeler.

Roadside springs are a source of pure, clean drinking water.
Roadside springs are not considered a reliable, safe drinking water supply.
Many people use natural springs as a source of drinking water. There is a mystique associated with springs, and a general public perception that clear, flowing, spring water is pure and natural, better tasting and free of contaminants compared to the local municipal water supply or private wells. In the majority of cases, these perceptions are not valid scientifically. Natural springs are not considered to be a reliable, safe water supply.
Who monitors roadside springs?
Most roadside springs are not routinely tested and monitored, and are not adequately constructed and protected against surface contaminants. In a recent study of approximately 100 roadside springs in Nova Scotia, 94% of the samples had total coliforms present, and 29% of the samples had fecal coliforms present. These results raise serious concerns about the sanitary quality of many of the roadside springs which are being widely used by the public.
At times there is a
Boil Water Advisory sign at our local roadside spring. If there is no such sign, is the water safe to drink?
The absence of a boil advisory sign does not mean that the water is safe. Historical results indicate that the water quality of roadside springs fluctuates. Coliform bacteria are sometimes absent, sometimes present, at the same spring at different times. Many springs have been posted with a boil advisory sign, but unfortunately the signs are often removed. In the past, where pipes have been removed from various springs to discourage their use, the pipes have often been replaced by members of the public.
If I experience a problem with the water in my well and a roadside spring is my usual "back-up", where else can I get water?
If you experience a problem with your well, or do not like the taste of your municipal or private supply, you are advised to consider alternative options to roadside springs. Other sources of supply, such as bottled water, are available. Point-of-use treatment devices can be installed at a tap normally used for drinking water. Please be aware that such treatment devices need care and maintenance to work properly.

How to open, view and edit a PDF-Healthcare file.
If you work in healthcare, you may have encountered PDF-Healthcare documents, commonly abbreviated to the file type PDF/H.

Learn more about this PDF subset developed by Adobe and AIIM and explore the origins of PDF subsets in general. We'll also explore how PDFs are used more broadly in healthcare.
What you'll learn.

What is a PDF-Healthcare file?

PDF-healthcare, commonly known as PDF/H, is a specialist PDF file type subset. Adobe created it alongside relevant experts to focus specifically on healthcare. This originated after the PDF format was made an ISO (International Organisation for Standardisation) standard. However, while the PDF/H is not an ISO standard itself, unlike some other subsets: it is a best practice standard.

To understand how these PDF file type subsets work, think of the original PDF format at the top of a family tree or management structure. Then, on the next row down, sit the PDF subsets, including PDF/H.

What does PDF-Healthcare stand for?

PDF stands for Portable Document Format and PDF/H stands for Portable Document Format for Healthcare. The /H is what's known as a 'subset' of the original PDF file type specification. There are several of these PDF subsets, each dealing with a different industry, sector or specialism.

History of the PDF-Healthcare file.

The PDF/H was developed in 2007, when Adobe made it possible to create 'subsets' of its iconic PDF technology. But to talk more about the history of PDF/H, we must first discuss the original PDF file type.

Humble lunchroom beginnings.

The story of the PDF or Portable Document Format, begins in the early 1990s. In those days, the entire Adobe team could fit in the lunchroom at its Mountain View HQ.

Adobe co-founders John Warnock and Charles Geschke wanted to make it possible for people to view files universally, regardless of whether they were using a Mac, Windows or UNIX. Believe it or not today, back then every system presented files in its own way - creating havoc for document authors.

PDF changed all that. Launched with the Adobe Acrobat Reader in 1995, the PDF format created files that looked the same on every computer.

Opening PDF up to the ISO experts.

Until the mid-00s, Adobe controlled the specification of the PDF. But in 2007 it released the technical spec to the American National Standards Institute (ANSI), the Association for Intelligent Information Management (AIIM) and the International Organisation for Standardisation (ISO).

Experts at ISO soon defined the PDF an ISO standard - ISO 32000.

ISO defines its standards as 'a formula that describes the main way of doing something' based on agreement between relevant experts.

The arrival of sector specific PDF subsets.

Soon after the PDF was made an ISO standard, experts began working on PDF subsets for specific industries. One of these was PDF/H - the healthcare-focused PDF. Some of these subsets became stand-alone ISO standards, others were considered best practice guides. PDF/H was a best practice guide, mostly developed by Adobe and the experts at AIIM.
What are PDF-Healthcare files used for?

PDF/H is used in the medical and healthcare sectors, particularly in the US. Medical professionals like doctors and researchers will often encounter these files. They're not typically used in the UK.

In the US, the Health Insurance Portability and Accountability Act (HIPAA) governs the protection of health data. Under the HIPAA Privacy Rule, US healthcare providers must meet minimum standards for electronic documents that include people's personal data.

The PDF/H standard was created in line with the HIPAA guidance for secure management of patient records in the US.

PDFs in healthcare - the bigger picture.

Moving away from the PDF/H file subset, we'll look briefly at the use of PDFs more broadly in healthcare.

 - In the UK, the NHS specifies accessible PDFs, known as PDF/UA. UA stands for 'Universal Accessibility' and PDF/UA is an ISO-defined standard. This differs from PDF/H, which is a set of guidelines rather than an ISO standard.
 - When NHS professionals use PDF/UA documents, they're also advised to create web content equivalents.

Things the NHS may use PDF/UA files for include:

Digitising documents designed for printing.

If you have a document related to a public information campaign, for example a poster or a leaflet, you could use a PDF to digitise this and share with people via your GDPR-compliant email mailing lists.

Annual reports and similar documents.

If you compile reports on behalf of a health organisation as part of your role, your organisation may choose to use PDF tools to create them. Examples could include the annual report of a health trust.

One example of how the NHS has used accessible PDF/UA files is to digitise the documents on its website for the NHS Long Term Plan. Doctors, nurses, patients' groups and subject-matter experts all fed into the plan. And you can download a PDF version of it direct from the site. The NHS follows Adobe guidance on ensuring these PDFs are accessible.

PDF/H FAQs.

What is a healthcare system PDF?

A healthcare system PDF is a subset of the Adobe PDF format. Adobe developed it alongside experts at the AIIM data management organisation for use in the US healthcare sector. It arrived soon after Adobe opened the PDF format to the International Organisation for Standardisation, but the PDF/H file isn't an ISO standard itself.

What PDF subsets are ISO standards?

When Adobe opened the PDF standard to the International Organisation for Standardisation, the PDF format itself became an ISO standard with several PDF subsets, which became ISO standards in their own right. The PDF subsets made into ISO standards were PDF/A (PDF for Archive) and PDF/X (PDF for Exchange).

When was the PDF made an ISO standard?

Officials at the International Organisation for Standardisation (ISO) defined the PDF format as an ISO standard in 2007. The standardisation came years after PDF first launched in 1993, but Adobe worked with experts to develop technical specifications for ISO from 1995 onwards. In 2021, the ISO standard for the PDF was revised periodically to ensure it kept pace with standards and technology. It was most recently revised in 2017 and 2021.

What's the difference between PDF and PDF/H?

The main difference between PDF and PDF/H is that the PDF/H was designed specifically for use in US healthcare, whereas you can use the standard PDF format across many different industries and practical applications. The PDF is its own ISO standard, whereas the PDF/H is a best practice guide.

PDF/A vs PDF/H - how do they differ?

PDF/A stands for PDF Archive. It's another PDF subset, like the PDF/H. Unlike PDF/H, however, PDF/An is an ISO standard in its own right (19005-1). PDF/An is concerned with ensuring electronic documents retain the same visual appearance over time, according to the PDF Association.

Ion Channel Based Bio-Synthetic Modulator for Diffusive Molecular Communication
Featured Articles
In diffusion-based molecular communication (DMC), a transmitter nanomachine is responsible for signal modulation. Thereby, the transmitter has to be able to control the release of the signaling molecules employed for representing the transmitted information. In nature, an important class of control mechanisms for releasing molecules from cells utilizes ion channels which are pore-forming proteins across the cell membrane. The opening and closing of the ion channels is controlled by a gating parameter. In this paper, an ion channel based modulator for DMC is proposed which controls the rate of molecule release from the transmitter by modulating a gating parameter signal. Exploiting the capabilities of the proposed modulator, an on-off keying modulation technique is introduced and the corresponding average modulated signal, i.e., the average release rate of the molecules from the transmitter, is analyzed. However, since the modulated signal is random in nature, it may deviate from its average. Therefore, the concept of modulator noise is introduced and the statistics of the modulated signal are investigated. Finally, by assuming a simple transparent receiver, the performance of the proposed on-off keying modulation format is studied. The derived analytical expressions for the average modulated signal are confirmed with particle based simulations. Our numerical results reveal that performance estimates of DMC systems obtained based on the assumption of instantaneous molecule release at the transmitter may substantially deviate from the performance achieved with practical modulators.

Although it is often overlooked, Lab colour is an extremely useful colour space in Photoshop that enables you to separate luminance information from colour information.
The more familiar RGB colour space achieves colour and brightness through mixing channels of red, green and blue light. By mixing the three channels, each with its own level of colour and saturation, an overall range of tones and colours is achieved.
Conversely, Lab splits all the colour information into two channels, but separates the lightness, or luminance, onto a third independent channel. This difference in channel make-up enables some eye-popping colour treatments and corrections that just aren't possible in RGB, all without compromising the luminance, contrast or detail of the image.

- Perkin Elmer Victor 3 140-011 Mulitlable Plate Counter
- Listing Reference:
VICTOR3™ Multilabel Plate Counter
General Description VICTOR3 is a multilabel, multitask plate reader for all light-emitting and light-absorbing detection technologies including: fluorescence (top and bottom), luminescence, absorbance, UV absorbance, time-resolved fluorometry, and fluorescence polarization. You chose the detection technologies you need and upgrade as your needs change. Select from a basic fluorescence and luminescence model, to the fully-loaded VICTOR3 V. Add other options at any time. A small bench top unit, VICTOR3 can operate as a stand-alone instrument or can integrate into a robotic system.
Fluorescence (340 – 850 nm)
Dual ratio measurements
Top and bottom fluorescence
Photometry (340 – 800 nm) UV Photometry (260 nm/280 nm) Time-resolved Fluorometry (TRF)
Dual window TRF
Dual emission measurements
Fluorescence Polarization (400 – 850 nm) VICTOR3 counting modes are always accessible. In the same protocol, even for the same well, you can freely use several different counting modes.
1. Kinetics VICTOR3 handles both fast and slow time kinetic measurements. The specific delays and repeats can be defined by plate, row or well. Built-in temperature control, dispenser and shaker are important for many kinetics applications.
The same plate can be measured automatically up to 99 times in succession. Maximum delay between measurements can be set to 3600 seconds.
Specific operation sequences can be defined by well or by row. The same well can be read up to 100 times.
2. Scanning Cell applications benefit from reading several points in one well. In VICTOR3 the number of readings (max 100 points) and the distance between the spots can be defined within the same well and distributed in a squared or rounded area. The scanning function is also suitable for reading small membranes, chips and slides. The minimum stepping is 0.1 mm. 3. Dual ratio measurements In VICTOR3 you can define two excitation/emission filters for one label and measure without the need for any internal calibrations of serial PMT. With a dispenser, it is the perfect system for Ca2+ modulations and other similar studies. 4. Top and bottom reading Fluorescence readings can be taken from the bottom or top. Top reading is the most efficient counting method when no lid is used because no plastic surface has to be penetrated. Adherent cells and lids require bottom reading for highest counting efficiency. The software enables both top and bottom reading to be used in the same run. 5. Dual window TRF The dual window TRF option enables recording of two separate windows in one flash cycle. It is important to follow a change in the emission profile of a lanthanide chelate in energy transfer applications especially when the actual energy transfer might be affected.
The wide range of counting modes together with necessary options opens up a huge range of application possibilities:
Cell-based: cytotoxicity, cell viability, cell quantification, cell proliferation, cell adhesion, NK cell activity, oxidative burst, calcium uptake, reporter gene, phagocytosis
Binding studies: immunoassays, receptor assays
Kinetics: enzyme activity, Ca2+ measurements and other ion measurements
Molecular Biology: hybridization, DNA quantification, gene expression, PCR product quantification
Quantifications: Protein, ssDNA, dsDNA, cells, bacteria, cytokines
The instrument's uniquely designed direct optics ensure the very best sensitivity and working range with all technologies.
The instrument is built around two lamp systems with respective filter arrangements for wavelength selections.
1. Continuous light source (cw) for fluorometric and photometric measurements:
Tungsten-halogen lamp, 75 W, lifetime typically > 300 h, spectral range 340 – 800 nm.
Changeable rotatable filter wheels, provided with 8 or 4 positions for 15 or 25.4 mm filters.
2. Flash light source for TR-fluorometric and UV absorbance measurements:
UV Xenon flash tube 1500 V.
Filter slide provided with three positions.
The detection units are chosen as the best technical solutions for each of the various technologies. 1. R 1527P photomultiplier tube for fluorometry, luminometry and TR-fluorometry:
Digital Photon counting, high cathode sensitivitywith low noise photo cathode.
2. Photo diode for photometry use.
A wide range of high quality filters is factory installed. These filters cover the most common wavelengths used in fluorometric and photometric applications. Additional filters are available upon request. Depending on the model and enabled technologies following filters will be supplied:
Absorbance: 405 nm, 450 nm and 492 nm
UV absorbance: 260 nm and 280 nm
Excitation 355 nm and 485 nm
Emission 460 nm and 535 nm
Excitation 340 nm
Emission 545 nm, 572 nm, 616 nm and 642 nm
Additional 665 nm emission filter for LANCE™comes with red sensitive PMT
Excitation 480 nm and 531 nm
Emission 535 nm and 595 nm
The measuring height can be defined as a parameter in your protocol. This provides the option of setting the focus point in a range from 3 – 18 mm in a normal 96-well plate. This is useful for measuring filter plates, cell layers and membranes, etc. It also enables you to reduce sample volumes efficiently.
Adjustable Lamp Energy
The lamp energy level is adjustable through the software. The acquired value is saved with your label. Whenever you use the same label, the same setting is used, which guarantees highly reproducible counting facilities.
The shaker accommodates the wide range of plates and applications for which VICTOR3 is suited. Three modes are available: linear, orbital and double orbital. The duration, speed and amplitude of shaking can all be defined by the user.
Sample Changer and Conveyors
Several sample loading methods can be used with VICTOR3.
Manual loading (one plate at a time)
Stacker loading (up to twenty plates per load)
The stacker supports microplates with these dimensions:
Length: 127.2 – 128.2 mm
Width: 84.5 – 86.0 mm
Height: 10.0 – 25.0 mm
Skirt: 1.5 – 6.5 mm
The plate stackers are robust metallic towers, which are easy to lift into place and remove. Each stacker carries 20 plates a time. 40 plate stackers are also available.
When used with a robot, the VICTOR3 reader is usually linked through OLE automation—ActiveX/COM interfaces. OLE and VICTOR3 software provide the basis for seamless integration and instrument control. The robot and the counter work as a unit.
All types of microplates from 1 – 1536 wells are compatible with the instrument. Photometry, time-resolved fluorescence, fluorescence intensity and fluorescence polarization technologies are applicable with 1536-well plates. Non-standard configurations can be defined in the workstation software. Petri dishes, slides, filters, Terasaki plates, and PCR plates are all suitable for VICTOR3. Opaque plates (black and white) can be used for luminescence samples as well as for all fluorescence measurements because of the epifluorometer mode. Filterplates and membranes can also be used. For absorbance measurements, a clear bottom plate is required.

New graphics engine imperils users of Firefox and Chrome
Disable WebGL now, researchers warn
The US Computer Emergency Readiness Team is advising users of the Mozilla Firefox and Google Chrome browsers to disable a recently added graphics engine that can be exploited to steal data or crash end user computers.
The web standard known as WebGL opens the browsers to serious attacks, including the theft of images or denial-of-service attacks, independent research consultancy Context Information Security recently warned. The technology made its debut in version 9 of Chrome and was added to the recently released Firefox 4. WebGL is also present in builds of Opera and Apple's Safari.
"Based on this limited research Context does not believe WebGL is really ready for mass usage," Context researcher James Forshaw wrote. "Therefore Context recommends that users and corporate IT managers consider disabling WebGL in their browsers.
The technology is designed to render web-based 3D graphics by allowing the browser to have greater access to a computer's graphics hardware. Until now, the security of graphics gear hasn't been much of a concern, but the wide availability of WebGL should change that. Malicious web masters could exploit inherent weaknesses in the standard to cause computers to display the infamous blue screen of death or steal potentially sensitive data.
A Google spokesman didn't address the claims in the Context report head on, but did offer the following:
Many parts of the WebGL stack, including the GPU process, run in separate processes and are sandboxed in Chrome to help prevent various kinds of attacks. To help ward off lower level attacks, we work with hardware, OS, and driver vendors to proactively disable unsafe system configurations and help them improve the robustness of their stack.
I'd also point out that Chrome doesn't run on some system configurations if lower level stack issues are identified. This is a key intermediate step to help protect Chrome users.
The spokesman didn't say if these measures are enough to prevent the Webgl vulnerabilities described by Context from being exploited in Chrome.
A spokesman for the Khronos Group, which maintains the WebGL standard, similarly didn't address the Context report directly in an email to The Register. Instead, he referred to an official statement that said the graphics engine comes with an extension "specifically designed to prevent denial of service and out-of-range memory access attacks from WebGL content."
The extension, known as GL_ARB_robustness, "has already been deployed by some GPU vendors and Khronos expects it to be deployed rapidly by others," the statement continued. "Browsers can check for the presence of this extension before enabling WebGL content. This is likely to become the deployment mode for WebGL in the near future."
The statement didn't name the GPU manufacturers or say what percentage of shipping GPUs make use of the measure.
On Tuesday, members of the US-CERT echoed the advice that WebGL be disabled. So far, neither Context nor CERT has given instructions for turning off the standard in various browsers.
In Firefox 4, type "about:config" (minus the quotes) into the address bar and set webgl.disabled to true. In Chrome, get to the command line of your operating system and add the --disable-webgl flag to the Chrome command. On a Windows machine, the command line would be "chrome.exe --disable-webgl". ®
This article was updated to include comment from The Khronos Group. It was later updated to correct the types of attacks Context said WebGL is susceptible to. The report doesn't include the possibility of code-execution attacks, as incorrectly reported earlier.
