I'll use an example from JavaScript to help clarify my question. Let's assume I have the following object:
sports = {
 soccer: {...},
 basketball: {...},
 baseball: {...}
If at some point in my script I have a variable, sportString, that simply holds a string, I can dynamically call one of the sports objects in the following way:
This frees me from having to use a bunch of nested if statements, testing the value of the string such as:
if(sportString ==='soccer'){
}else if(sportString === 'basketball){....
So, my question is how can I accomplish something similar to sports[sportString] in Objective-C, if sportString is an NSString object?

Use an NSDictionary as your sports object. Then you can do lookups like this:
[sports objectForKey: sportsString];

Thanks. Giving this one the answer since it's the first. – maxedison Jul 9 '11 at 11:47
The people saying you should use NSDictionary for general key/value storage are 100 % right. However, I think it's useful to know that you can call a message specified by a string:
SEL selector = NSSelectorFromString(@"foo"); // Or _USER_(foo) if you know it at compile time
id value = [object performSelector:selector];
You can also use selectors with up to two arguments, as long as they take objects:
SEL selector2 = NSSelectorFromString(@"setFoo:");
[object performSelector:selector2 withObject:value];
It's possible to invoke arbitrary methods using IMPs or casting objc_msgSend(), but now I'm getting way beyond the scope of your actual question. :-)

Thanks for posting this. Definitely useful to know about NSSelectorFromString and performSelector. I really appreciate it! – maxedison Jul 9 '11 at 16:23
Your JavaScript object sports would typically be an NSDictionary or NSMutableDictionary. Example:
NSMutableDictionary *sports = [NSMutableDictionary dictionary];
[sports setObject:@"Foo" forKey:@"soccer"];
[sports setObject:@"Bar" forKey:@"basketball"];
NSString *sportString = @"soccer";
NSString *sportValue = [sports objectForKey:sportString];
NSLog(@"%@", sportValue); //logs "Foo"

Grange Insurance Headquarters Expansion
The incorporation of Green Infrastructure into urban sites has gained broader acceptance as a way to reduce stormwater runoff into nearby rivers and waterways. The Grange Insurance Headquarters expansion in urban Columbus, Ohio, is an excellent example of the connection between Green Infrastructure and an urban site. EMH&T provided civil/site engineering for this 10-story office expansion in the Brewery District of Columbus. To meet Ohio EPA and City water quality regulations, numerous atypical sustainable stormwater techniques were initiated, including: a complex hydraulically designed raised runnel system that channels roof rainwater into a rain garden, water storage for irrigation, three buried detention systems, and a planter/buried tank combination releasing captured stormwater into a public combined sewer system. With these systems in place, the development site is equipped to optimize post-construction water quality treatment for frequent rainfall events and also manage larger, infrequent storm events. The green infrastructure features designed for this development site reduced construction costs by 25% compared to a more traditional buried pipe system.

text: Abstract Biologically produced compounds preserved in ancient ceramics can provide invaluable information on the vessel contents. Analysis and interpretation of these so-called archaeological "residues" is therefore important for understanding and reconstructing aspects of social and cultural behaviors of ancient societies. Based on the reaction of unsaturated compounds with iodine, we developed and apply two new methods. The first is a simple and relatively rapid method for assessing the amounts of unsaturated compounds in archaeological ceramics using X-ray fluorescence (XRF). We show that this method is a reliable indicator for assessing the general preservation state of the organic material and therefore a potential pre-screening method for identifying ceramic samples suitable for organic residue analysis. The second complementary approach, based on the same iodine reaction, makes it possible to map the unsaturated molecules on ceramic surfaces at a scale that enables to correlate organic matter distribution and the underlying mineral grains using a scanning electron microscope (SEM) equipped with an energy dispersive spectrometer (EDS) detector. With this method we show that the extent of adsorption of lipids onto ceramic surfaces varies with the surface properties of the different minerals in the ancient ceramic, with calcium containing minerals showing the highest affinity for compounds with unsaturated bonds. The ceramic substrate therefore influences the types of organic compounds bound and hence preserved in the ceramic. Fundamental information obtained using this method is essential for better interpreting molecular assemblages extracted from archaeological ceramics.


onfocus event
Fires when the object receives focus.
HTML 4.01 Specification, Section 18.2.3
Event Property object.onfocus = handler;
attachEvent Method object.attachEvent("onfocus", handler)
addEventListener Method object.addEventListener("focus", handler, useCapture)
Event information
Event handler parameters
pEvtObj [in]
Type: IHTMLEventObj
Standards information
When one object loses activation and another object becomes the IHTMLDocument2::activeElement, the HTMLInputFileElementEvents2::onfocus event fires on the object becoming the IHTMLDocument2::activeElement only after the HTMLInputFileElementEvents2::onblur event fires on the object losing activation. Use the focus events to determine when to prepare an object to receive input from the user.
Elements cannot receive focus until the document is finished loading.
For Microsoft Internet Explorer 5.5 and later, focus on a document, and the IHTMLDocument2::activeElement of a document can be managed separately. The synchronous events HTMLInputFileElementEvents2::onactivate and HTMLInputFileElementEvents2::ondeactivate provide better control for managing activation changes.
As of Microsoft Internet Explorer 5, elebrowserments retain focus within the current history when the user returns to a page. To avoid firing the HTMLInputFileElementEvents2::onfocus event unintentionally for an element when the document loads, invoke the IHTMLElement2::focus method on another element.
Sets focus to an object.
To invoke this event, do one of the following:
The pEvtObj parameter is required for the following interfaces:

//Before writing about the Compare and Contrast marketing in Japan and in the United States, it is essential to know about the economy of the two Countries. One should know about the exporting condition of these two Countries, which further will assist in performing the Comparison and contrast, in an effectual manner.//
Marketing is defined as the process of creating, pricing, distributing and promoting goods, services, individuals, places or ideas. (Kotler, 2000). Japan is turning to be a fast changing economy as far as its markets are concerned. Companies find it hard to enter Japanese market. In comparison, it is relatively easier to enter the US markets. Before 1990, Japan had an image of a prolific exporter but a reluctant importer. There are various trade barriers to check against the invasion of foreign companies. Japan has the world's second largest GDP even after facing recession in 1990's. This amounts to two third of the USA's GDP (Japan's Business Environment in the Globalizing Economy, 2008).
Japan is the number one exporter in production of cars, ships, robots and machine tools. Japanese markets have been very lucrative for investors. One of the most peculiar features of Japanese industry is that it has been protected by competition. For example, Finance industry was well protected by the government during recession. In the US, this kind of protection is not offered.
Marketing Environment can be defined as the sum total of...

A Thermo-Hygrograph is a chart recorder that measures and records both temperature and humidity (or dew point). Similar devices that record only one parameter are a thermograph for temperature and hygrograph for humidity. Uses a bi-metallic strip for temperature and one human hair bundle for humidity. Includes one red and blue felt –tipped pen to record the reading.
A thermograph is usually configured with a pen that records temperature on a revolving cylinder. The pen is at the end of a lever that is controlled by a bi-metal strip of temperature-sensitive metal which bends as the temperature changes.

Health Canada is warning parents and caregivers to get rid of a popular old toy that is no longer considered safe after the recent choking death of an infant.
The department says Fisher-Price Little People toys made before 1991 are a choking risk for small children and should be discarded in a way that ensures they aren't re-used or resold.
The company changed the design of the popular toys in 1991 after seven deaths and one serious injury in children under three who had choked on the little figurines.
The newer style is chunkier and too big to go down the throat of a young child.
Health Canada issued the warning after recently learning of a death of a 10-month-old child who had been playing with one of the old-style Little People toys.
The death occurred after an older "Little People" figure became lodged in the child's throat. This incident has brought attention to the fact that these products are still used in play in Canadian households. Additionally, these products continue to be sold in some second-hand retail establishments (including internet retailers and resellers).
The older toys are about two centimetres in diameter, while the newer ones are about three centimetres wide, as well as being taller and chunkier.
Fisher-Price launched a public information campaign in 1992, entitled the "Family Alert Program," in response to reports of seven fatalities and one serious injury related to the use of these figures by children under the age of three.

Brisker uses a gentle heating element to warm the interior temperature to ~120 degrees Fahrenheit. Warmer air spreads moisture out, so items inside the Brisker dry out and stay crunchy.
This all works because of the principles of relative humidity. With the air inside the Brisker about 40-50 degrees warmer than room temperature in your kitchen or pantry, humidity and moisture decreases inside of the Brisker relative to the humidity in your kitchen.
Here's a neat video explaining how relative humidity works.

Thousands of Victorians are signing up for Free TAFE courses to improve their employability in a post COVID-19 world.
They're taking advantage of the Victorian Government's Free TAFE for Priority Courses program. The scheme launched in 2019 and was expanded in June this year by an additional 10,000 places.
The program funds studies for Victoria's future high-demand jobs.
"We're giving Victorians workers and industry the skills they need to help us rebuild from coronavirus," said Gayle Tierney, Minister for Training and Skills and Higher Education.
Students across Victoria are snapping up the Free TAFE courses. Enrolments at TAFEs almost doubled in the first year, particularly among women, young people and mature-aged students.
Recently, the government added $163 million to its initial $172 million investment in the scheme. The latest courses to be added to the list include qualifications in health, mental health, the NDIS and construction.
The expansion to the Free TAFE program will come as a lifeline to many whose lives have been turned upside down by the pandemic.
Recent data from Seek shows that 8 out of 10 people have had their work impacted by COVID-19.
Speaking to the true depths of the crisis, the same research also shows 1 out of 4 people are working fewer hours.
Current unemployment rates are particularly grim for casual and contract workers, often in the younger age group. Of casual workers, 1 out of 3 have lost their jobs and 1 out of 5 contractors have lost their jobs since COVID-19.
Despite the fallout from the pandemic, we are seeing some positive trends.
The Seek research shows some industries have a growing demand for workers. These include healthcare, transport and IT.
And according to government predictions, job growth is forecast for health, construction, education and professional, scientific and technical services.
For workers who've lost jobs due to COVID-19, this could be the perfect time to retrain or upskill.
Through opportunities like the Free TAFE program, people can more easily shift from weakening industries to in-demand ones.
When you sign up for one of the Free TAFE courses, the government pays your whole tuition fees, which makes up the bulk of your fees.
You may have to cover some extra fees yourself, like student services and materials, but these won't break the bank.
To be eligible for a Free TAFE course, you need to meet one of two conditions. You have to be under 20 years old or enrol in a course at a higher level than your current qualifications.
The free courses include about 30 non apprenticeship courses and 20 pathway-to-apprenticeship courses.
Students who've enrolled in priority courses have had great success in their careers. Take Bea Hennessey, who did a Certificate III in Health Services Assistance (HLT33115) at Box Hill Institute.
"It was a perfect fit for me. After the first semester, I was ready to start my clinical placement at the Austin Hospital," said Bea.
"About two months after I completed my certificate, I'd been offered two positions there!"
Like Bea, Paul Yao took a leap forward in his building and construction career. After completing his certificate and diploma at Box Hill Institute, Paul started his own business and did a master's degree.
"My experience at Box Hill was so positive. Just take one step at a time. You can never imagine where learning will take you," said Paul.
"People ask if they should continue their studies. I always say, why not? Everything makes more sense when you study. I never imagined I'd be where I am when I first started."
Box Hill Institute is a Victorian TAFE with a track record of placing students in jobs, reporting 78% of alumni get jobs within the first 6 months of graduating.
Box Hill Institute also helps students into jobs through its Skills and Jobs Centres, where career advisors help students hunt for jobs and submit applications.
Box Hill Institute offers a number of the Free TAFE courses and many other government subsidised courses. To name just a few, courses span across health, nursing, education, horticulture, hospitality, cyber security and construction.
In addition to Free TAFE courses, the government subsidises another 1,000 courses. While these pay-outs don't cover the whole tuition, they do help with a good chunk of the course fees. Concessions are also available.

Essentially, we will define the distance to the focal plane and a blur radius. For each primary ray we find its intersection with the focal plane, \(\vec{p}\), and jitter the ray origin by an amount, \(\vec{d}\). We then define the new ray direction as \(\vec{r}=\vec{p}-\vec{d}\). Consequently, objects on the focal plane will appear in focus. Below is the addendum to the kernel() function.
 __vector dir = __vector(x - width / 2, -y + height / 2, 0 + width) + offset;
 __ray ray = { __vector(0, 0, 0), dir.unit() };
 u1 = rand_device[i*width*height*3+index+1];
 u2 = rand_device[i*width*height*3+index+2];
 r1 = 2 * M_PI * u1;
 r2 = u2;
 offset = __vector(cos(r1)*r2, sin(r1)*r2, 0.0) * blur_radius;
 __vector p = ray.origin + dir * (focal_distance / width);
 ray.origin = ray.origin + offset;
 ray.direction = (p - ray.origin).unit();

In order to interact successfully in social situations, a robot must be able to observe others' actions and base its own behavior on its beliefs about their intentions. Many interactions take place in dynamic environments, and the outcomes of people's or the robot's actions may be time-dependent. In this paper, such interactions are modeled as a POMDP with a time index as part of the state, resulting in a fully Markov model with a potentially very large state space. The complexity of finding even an approximate solution often limits POMDP's practical applicability for large problems. This difficulty is addressed through the development of an algorithm for aggregating states in POMDPs with a time-indexed state space. States that represent the same physical configuration of the environment at different times are chosen to be combined using reward-based metrics, preserving the structure of the original model while producing a smaller model that is faster to solve. We demonstrate that solving the aggregated model produces a policy with performance comparable to the policy from the original model. The example domains used are a simulated elevator-riding task and a simulated driving task based on data collected from human drivers.

Accurate control is provided by automatic progressive sequencing in the use of energy and minimizing wear and tear on electrical components. The sequencers are designed to apply power progressively to larger KW boilers. A factory-installed pressure sensitive sequential control reacting to steam boiler pressure progressively energizes and de-energizes heating elements through power contactors. A delay between sequencer steps before start-up and between each subsequent step eliminates power surges. Each sequencer is matched and factory pre-set to boiler system requirements.
Electronic progressive sequencers give accurate electronic control of multi-stage loads of the type used in steam boilers. Integral solid state light emitting diodes show active stages. Should a power interruption occur, all heating elements are instantly de-energized for safety. Upon resumption of power, the control will re-stage the loads one at a time.
The solid state sequencer operates on a 120v AC/60Hz, with each output relay rated 125VA at 120 AC.

The origin of the name Miriam is Hebrew
This is how Miriam is written in Hebrew:
מִרְיָם = Miryam
The biblical meaning of the name Miriam is rebellion.
Miriam was the elder sister of Moses and Aaron
The name Miriam appears in the bible in the following verses:
Exodus 15:20 KJV
And Miriam the prophetess, the sister of Aaron, took a timbrel in her hand; and all the women went out after her with timbrels and with dances.
Exodus 15:21 KJV

The last remark needs fact-checking. It actually works - within
limits. It's a fun feature, but I don't really use it much.
What you have to do to make it work depends on your platform. On Mac
OS X, I first created a little script
/usr/local/bin/math
containing the following two lines:
#!/bin/sh
/Applications/Mathematica.app/Contents/MacOS/MathKernel "$@"
The purpose of this is simply to make the command "math" appear in the
path visible to LyX, and point to the Mathematica Kernel (so obviously
this is Mac specific, and I don't know the PC equivalent). Then
whenever you have a calculation that you want to do in LyX, do the
following:
* Open a math environment.
* Type the Mathematica expression you want to evaluate (e.g.: Sin[.2])
* Highlight the expression
* While you are still in that math box, go to Edit > Math > Use
Computer Algebra System > Mathematica
* Magically, an equals sign and the result of the evaluation will
appear in the LyX math box.
In general, in particular when graphics is involved, I would just work
with the Mathematica Notebook and the LyX editor side by side, and
copy/paste between the two. In LyX 1.6, you can paste graphics into
LyX from the clipboard. Equations in Mathematica's TeXForm can be
pasted directly into LyX math environments.
In the other direction, you can copy LaTeX from LyX into Mathematica
as follows:
* enter the desired math expression in LyX (e.g., \sin\alpha)
* select all the _contents_ of the math box, but not the math box
object itself (i.e., stop highlighting when you reach the end of the
math inset).
* Copy
* Paste literally into a Mathematica Cell, perhaps wrapped by
something like ToExpression["\sin\alpha", TeXForm] (where the pasted
text goes between the quotation marks)
* The result can then be used in Mathematica Labels etc.
Although LyX has a non-LaTeX internal file format, everything it does
goes through LaTeX, and in particular all its equations can be
understood by other LaTeX-aware programs. One may still ask why anyone
would you use LyX instead of Mathematica to write equations. I think
this has already been addressed, and it may really be a matter of
taste - but it's worth pointing out that LyX has unlimited Undo and
version control (there's more, but I better stop here).
As for the customization of the LyX output, it's true that this isn't
trivial if you don't know much LaTeX. The LyX-users mailing list would
be a place to start, they are very helpful...

Quality Assurance
Further to calibration (measurement of sensitivity), the function of the twilite can be tested using a long (e.g. multiple of 3 to 5 times the tracer half-life) acquisition of a fixed activity solution (e.g. 5 MBq/ml for 0.58 mm ID catheter as used in rats, 2 MBq/ml for 1 mm ID as typically used in humans).
Using the PSAMPLE Correction tool, the data from the long acquisition can be loaded in the Correction tab. After subtraction of the background counts using the Offset: Enter method (enter the background counts calculated during calibration), apply Decay Correction with the appropriate isotope half time. The resulting Corrected & Calibrated [kBq/cc] (green squares) should be a linear, horizontal, line. Application of the Calibration factor and Branching Ratio correction is not necessary.
Additionally, a single exponential function can be fitted to the non-decay corrected data using the PKIN tool (if licensed). The half time of the exponential should match the isotope half-life (in minutes).
Turn off Decay Correction, and use the Kinetic Modeling button to open the TAC export dialog. Send the curve to the PKIN tool using the Send [SET] button (or Send [ADD] if other projects are already open in PKIN).
PKIN opens on the Blood tab. Select the 3 Exponentials model from the list, deactivate the second and third exponentials (uncheck Amplitude 2/3 and Halftime 2/3, set Amplitude 2/3 to zero), and enter a reasonable starting value for Halftime 1 (e.g. 100 minutes for F-18). Ensure that Delay and Begin are set to zero. Activate Fit whole blood to fit the model.
Once fitted, the resulting model curve can be highlighted by clicking the Whole blood model button in the legend below the plot window.
Amplitude 1 represents the starting average counts, and Halftime 1 should closely match the half-life of the isotope used in the measurements.
Sources of error include:
1.Inaccurate definition of the background in Offset: Enter. Determine the background counts from a calibration or simple background measurement shortly before the long decay acquisition.
2.Excessive starting activity (the twilite is linear, with deviation < 1 %, up to 6,000 counts/sec coincidences). If initial coincidences are above this threshold, stop the acquisition and restart after a suitable delay.
3.Continuing to acquire data after reaching the background level (flattening of the data curve tail). Resampling in the PSAMPLE Correction tool can be used to remove the tail using Remove Sampling Segment and an appropriate time window.


What is a SOG ?
A Sog toilet kit dispenses with the need for smelly chemicals being stored / purchased and used in your motorhome or caravan toilet systems.
Opening the toilet valve activates a low powered extraction fan which consumes a measly 0.43 watts.
The fan creates a mild negative pressure within the cassette which draws oxygen into the cassette from the bathroom area.
This drawing in or air effectively seals off odours contained in the cassette and draws into the cassette personnel odours during use.
The sog fan only operates when the toilet is in use. Driving smells no longer exist.
All toilet cassettes are placed in "release mode" when the cassette is in position. This results in ammonia and methane odours/pressure circulating in the interior of the vehicle if sealing of the toilet chamber is not 100%, which is close to impossible. SOG systems provide a sealed pipe path, for odour/pressure to passively release, via a charcoal filter, to the outside of the motorhome.
The underlying principle of SOG ventilation systems is the passing of oxygen over the surface of the waste, whether this is accelerated when the fan is in use or passively as pressure escapes from the cassette via the SOG piping system to the outside of your vehicle. This is the natural curing "oxidisation" process used by Sewerage Treatment plants.
Naturally treated waste has far less smell when emptying the cassette and you can use normal toilet paper.

The Heartland Latino Leadership wishes to thank artist Linda Garcia for her design contributions. Each element of the design incorporates symbols that express the strength, hopes, and culture of the Latino community. Taken together, they relay an even more powerful message of progress toward a fulfilling destiny.
HEART is for the heartland and for the real leadership which must involve your Corazón (Heart and Spirit) as well as the mind.
HAND symbolizes hecho en Mexico or handmade in Mexico. Although all Latinos are not of Mexican heritage, this symbol was chosen because leadership needs hands on efforts to grow a strong community. Many indigenous people have a strong history of folk art.
SEED held in the palm of the Hand; the seed symbolizes growth. Leadership, like a planted seed, benefits not only the sower but a multitude of others.
FRIEZE within the Heart, the step like symbol is originally from Vera Cruz.
This ancient symbol was chosen to represent a historical perspective. You must know where you come from to know where you are going. One must perpetuate their heritage.
RIVERS the outside lines of the Heart represent the Missouri and the Platte Rivers, reinforces the heritage of the Heartland, and invokes it as a new gathering place.

Why a Timing Belt Is Necessary for a 3D Printer and How It Works
There are many different types of industrial machines that rely on belts and timing belts to function as expected. Take a 3D printer, for example. A 3D printer timing belt serves specific functions inside these amazing pieces of equipment. Without the timing belt, your 3D printer would not be able to execute the computerized design commands. Here is more about how the 3D printer timing belt works inside these machines, and why the belt is necessary.
Every Layer of Printed Material Relies on the Printer Head Moving at a Specific Speed
The belt controls the movement of the printer head. It also controls the speed of the printer head so that each layer of material printed is precise and your project does not come out looking lopsided. The belt is attached to the printing arm and head, and it retracts and extends the arm and head to help print your project.
Without the Belt, the Arm and Head of the Printer Can't Move
The timing belt is necessary to the function of the arm and head. If the timing belt is damaged or non-existent, your 3D printer will only hum and whine and drop melted material into a misshapen lump on the platform. Additionally, if the timing belt is worn, it will cause flaws in your printed project because the belt will wobble slightly or cause the arm and head to print in a way that is not uniform.

RC Input and Output
RC Input
RC Input is a key part of any autopilot that gives the pilot control of the airframe allows them to change modes and also gives them control of auxiliary equipment.
Edge supports both S.Bus and PPM input, which combines information about all PWM channels from the receiver in one sequence, which could be transferred over single wire. Channel values sent by remote controller will be decoded and then used for servo control.
You need to calibrate radio before using it.
By default the RC input channels are:
 - Channel 1: Roll input
 - Channel 2: Pitch input
 - Channel 3: Throttle input
 - Channel 4: Yaw input
 - Channel 5: Flight mode
 - Channel 6: (Optional) Tuning
These can be changed by setting the RCMAP_ROLL, RCMAP_PITCH, RCMAP_THROTTLE and RCMAP_YAW parameters. After changing any of these parameters the flight controller should be rebooted.
To set modes of channels 7..12 select Vehicle Setup and then Flight Modes tab.
RC Output
RC Output is how ArduPilot controls servos and motors.
Edge has 12 available output channels.
To change channel configuration you can use SERVOx_ parameters. The "x" in this case is the channel number.
We do ask to NOT SET AUXILIARY FUNCTION SWITCHES TO RC7,8 USING HEX FRAME!
You can use Motors Test to check motor connection. In Vehicle Setup menu choose Motors.
Attention
Make sure the propellers are removed before using this. It can be dangerous.
Relay Switch
A "Relay" is a digital output pin that can be either 0V or 3.3V. Similar to a servo it allows the flight controller to invoke some action from another device on the vehicle. You can use it to control things like camera shutter, bottle drop etc.
Note
This feature available only on ArduCopter.
First you need to specify RELAY_PIN parameter in QGC Parameters:
Attention
Don't set digital pin to PWM channel used for control servos!
Next, configure pilot control of the relay. Choose previously selected Relay for one of the free channels in Flight Modes:
After that you can switch state of Relay Pin using your RC transmitter.

Roughly speaking, if you have an error of a factor of $1 \pm 10^{-15}$ in each multiply, the standard deviation is a factor of $1 \pm \frac 1{\sqrt 3}10^{-15}$ (assuming a uniform distribution). You need about 3 of these to lose the first digit, 300 to lose the second.
It isn't worth being too careful in this calculation, because if your number is stored in decimal, the fractional error changes by a factor 10 between a number that starts 10000 and 99999. In binary it is only a factor of 2, but the principle is the same.

Metadata Management Series: Weaving Asserted and Discovered Metadata into Your Data Fabric
This series of articles will show how knowledge graphs support the construction of scalable models that mix discoverable with explicitly asserted metadata to afford reasoning and policy enforcement. In this first article, we show how explicitly asserted metadata in a knowledge graph enables automated reasoning.
Data architects create models of their data assets for various purposes, including documentation, optimization, search, classification, and policy enforcement. These models contain "information about data" or metadata. Metadata such as the names and types of tables and columns can be discovered and maintained automatically. And some of these metadata can be automatically linked to one another to represent important relationships like the containment of a column in a table or the lineage of data among assets, such as when a table is constructed using an ETL script.
Unfortunately, some important metadata and some links that connect metadata cannot be discovered automatically. While this is not a new problem, we are seeing it increase as organizations migrate to the Cloud and begin to adopt architectural practices that separate and encapsulate data assets. Data architects compensate by building up a store of asserted knowledge – statements of fact about the semantics of data assets and of connections between them.
Asserted knowledge is another kind of metadata – one that references and depends on the discovered metadata that is automatically discoverable and maintainable using tools. Asserted knowledge is typically informal, and if it is recorded at all, it is in the form of code comments, documents, or spreadsheets. Despite its informality, architects rely on asserted metadata to reason or enforce policy to the point that business outcomes depend on its veracity.
We believe that to properly manage and enforce policy over data assets at scale, asserted metadata should be woven with discovered metadata into a knowledge graph that affords powerful reasoning.
Consider a hypothetical enterprise with two micro services:
- FundManager, which owns the XYZ_Txns table among others, and
- SecurityManager, which manages a system-of-record database of securities.
Suppose FundManager uses a lookup service provided by SecurityManager to look up securities based on some request parameters as depicted here:
Now imagine, that SECURITIES was created as follows:
CREATE TABLE SECURITIES( ID uniqueidentifier PRIMARY KEY, Ticker varchar(8) CUSPID varchar(16)... )
Suppose FundManager calls lookup to retrieve an authoritative ID to use as the value for a column named SecId when it creates new rows in the XYZ_Txns table. When the architect learns this fact, she realizes that if the tables were in the same database, she could relate SecId and ID by a FOREIGN KEY constraint, but because they live in different micro services, it is not possible to declare and enforce such a constraint.
That information was likely not discoverable automatically. Maybe SECURITIES once lived in FundManager where a FOREIGN KEY constraint enforced the connection between ID and SecId, but when a decision was made to split FundManager into two microservices, this information and the guarantee of data integrity were lost.
In any case, this semantic connection is significant and could be used to reason about compliance with certain governance policies. For instance, consider the requirement that the security attributes of every transaction in FundManager are auditable. Those attributes are not part of the XYZ_Txns table, but they are part of SECURITIES. If each attribute is declared NOT NULL in SECURITIES, if SecId is declared NOT NULL in XYZ_Txns (as it is), and if this asserted link from ID to SecId is akin to a FOREIGN KEY constraint, then the data architect should feel confident that the attributes are guaranteed to exist for each SecId and so the requirement is satisfied.
This example provides just one illustration of the kind of reasoning a data architect must do over the metadata she manages. Notice that a key step in this reasoning uses asserted knowledge that refers to metadata (the columns ID and SecId) that are discovered automatically. Without that step, the chain of reasoning breaks, which leaves her potentially in violation of this particular requirement. It is therefore critical that she records this assertion so that this reasoning can be automated. It is also important to protect this assertion from drifting with respect to the discovered metadata (columns ID and SecId) that it references.
The next articles in this series will discuss how to weave this kind of asserted metadata into our model and how to prevent drift. We will examine how the facilities of knowledge graph management systems help with practical issues that arise when managing models containing both types of metadata.
Semantic Optimization makes your complex data workloads more efficient, which in turn improves overall system performance and scalability.
Losing the Middle Tier
Business applications are traditionally complicated to understand and maintain because business logic tends to be scattered in separate tiers of growing code bases, while schema becomes rigid and brittle. The end result is that business logic dissolves in a soup of disparate application code.

Mountain Ash Fact Sheet
Mountain Ash
Common Name: Mountain Ash
Order: Myrtales
Family: Myrtaceae
Genus: Eucalyptus
Species: E. regnans
Size and Growth Rate: Mountain ash grows relatively quickly, with an average annual growth rate of 3 feet (1 meter). They are the tallest of the eucalypts, capable of reaching heights of up to 490 feet (150 meters) but generally grow to about 330 feet (100 meters). It's the world's tallest flowering plant.
Life Span: Mountain ash has an average lifespan of 400 years.
Reproduction: The primary form of reproduction occurs through dispersal of seeds. This process is often initiated during severe fires when intense heat releases seeds from their hard casings, called gumnuts. The seeds germinate on the forest floor, receiving a boost of nutrients from the ashes left behind from the fires, and flourishing in the sunlight which reaches the ground through now-bare tree branches. Mountain ash trees can also regenerate through shoots sprouting from dormant buds protected beneath the fire-insulated bark., or which are stimulated when trees suffer significant loss of top growth—though this form of regeneration happens far less frequently.
Appearance: The base of the tree is quite rough but, as the tree grows, this rough bark sheds large ribbons, leaving the highest part of the tree with a smoother exterior. The lowest branches are nearly 100 feet from its base. The mountain ash leaf varies in shape; clusters of white flowers blossom during Australia's summer and autumn months, January to March.
Habitat: The mountain ash grows in deep soil in the cool, mostly mountainous areas of Victoria and Tasmania on the Australian continent. These regions are located at an approximate altitude of 3,300 feet (1,000 meters) with an average annual rainfall of 47 inches (1200 millimeters).
Conservation Status: The species is not considered to be at risk of extinction.
Additional Facts:
 - Mountain ash is a common name given to other unrelated species of trees, such as the Fraxinus texensis in Texas, the Sorbus in North America, and the Sorbus aucuparia, found mostly in Ireland and Britain.
 - In addition to mountain ash, the species has also been referred to as Victorian ash, swamp gum, Tasmanian oak and stringy gum.
 - The Australian mountain ash is the tallest flowering plant, and the tallest of the eucalypts.
 - Only California coastal redwoods are taller, though their heights are comparable.
 - The species is an evergreen, maintaining its leaves year-round.
 - Mountain ash is part of a diverse group of plants known as Angiosperms, or flowering plants, classified for their seed, flower, and fruit production.
 - Its leaves produce volatile, highly combustible oils.
 - Mountain ash produces excellent hardwood timber prized by the lumber industry for building and paper products, and also provides essential habitat for a wide variety of birds and mammals, including the endangered Leadbeater's possum.

Negative zero error occurs when the '0' marking of the vernier scale appears before the '0' marking of the main scale. The error is -(0.1-y) cm. To correct the reading, we subtract the error from the measurement.
Negative Zero Error: If the zero of the Vernier scale is one the left of the main scale zero, then the zero error will be negative and zero correction will be positive. To find the zero error note the number of Vernier scale division which coincide with one of the main scale and multiply with least count.

Transparency International, Measuring and Monitoring Impact Movement-Wide
2013-Ongoing; Germany; Transparency International
Established in 2011, Transparency International's (TI) MEL unit is tasked with conceptualising, implementing and maintaining the organisation's overall monitoring, evaluation and learning system.
Broadly, the system focuses on three pillars; results, through monitoring the outcomes and results achieved through the organisation's programmatic work; performance, through monitoring standard organisational performance areas at the TI-Secretariat and Network levels; and impact, through monitoring the impact of the overall TI network.
The main objective of Itad's consultancy is to provide conceptual and technical support to the MEL unit in the conceptualisation, development and piloting of a Movement-wide approach to measuring and monitoring outcome and impact. Itad's team of three consultants is providing support in:
(1) Assessing the viability of having a Movement-wide approach to measuring and monitoring outcomes and impact. This includes scanning the sector as well as learning about the Secretariat and the Movement in order to understand whether such an approach would be suitable.
(2) Conceptualising a robust approach including the development of a strong underlying rationale, as well as a clear indication of the operationalisation potential, including resources' implications.
(3) Developing the necessary manuals, data protocols, tools, documents that facilitate implementation of the approach.
(4) Piloting the approach – this includes supporting the unit in the piloting of the approach at field and Chapter level.Image © Kenya Election Mural. Photo credit: Will Huen/Open Democracy

Overload Appropriate Operators

Operator overloading is like sugar: a little is sweet, but a lot will make
you sick. Ensure that you only use this technique for situations that make sense.
Implement operator +
Notice that the method is public static and takes both operators as arguments.
Code:
public static Vertex3d operator +(Vertex3d a, Vertex3d b)
{
return new Vertex3d(a.X + b.X, a.Y + b.Y, a.Z + b.Z);
}
The same principal can be applied to the -, *, /, %, &, |, <<, >>, !, ~, ++, and -- operators
as well.
Implement operator == and operator !=
These should always be implemented as a pair. Because we've already implemented a
useful Equals() method, just call that instead.
Code:
public static bool operator ==(Vertex3d a, Vertex3d b)
{
return a.Equals(b);
}
public static bool operator !=(Vertex3d a, Vertex3d b)
{
return !(a==b);
}
What if the type is a reference type? In this case, you have to handle null values for
both a and b, as in this example:
Code:
public static bool operator ==(CatalogItem a, CatalogItem b)
{
if ((object)a == null && (object)b == null)
return true;
if ((object)a == null || (object)b == null)
return false;
return a.Equals(b);
}
public static bool operator !=(CatalogItem a, CatalogItem b)
{
return !(a == b);
}

How Not to Choose an Expression
We sometimes have a requirement to select between two or more expressions dependant on user selections or some other condition. For example, this chart Expression.
 // Calculate with Commision
 SalesAmount - SalesAmount * CommissionRate)
 // Calculate without Commission
The if() will select one or the other sum() expression based on the value of the vWithCommmision variable. Because a variable is being tested — not a row value — only one sum() will be chosen for the entire chart.
If performance is important, this is not a good way to implement the requirement. QlikView does not "short circuit". Short circuit means to stop evaluating when the condition is true. QlikView will calculate both sums and then return one of those results.
Some people mistakenly believe that putting the above expression in a variable changes the behavior. This is incorrect. The if() evaluation is still done at the chart level and the performance impact remains.
A performant way to solve the requirement is to put each calculation into a separate chart Expression and use the Conditional property to select the Expression.
An Expression with a Conditional evaluating to False will not be calculated or displayed.
There is also the possibility of choosing the calculation in a variable, but you have to follow a few rules.
 1. The variable should return the string representation of the formula. Note the single quotes in the example below.
 2. The variable definition should begin with "=". This causes the if() to be evaluated only once.
 3. In the chart Expression, reference to the variable should be made with $(). eg $(vChooseCalc)
 SalesAmount - SalesAmount * CommissionRate)'

 1. Rob, I was recently informed that if you are desiging for the Ajax client you should NOT begin the variable definition with "=" as it impacts performance. Can you verify that is correct?
 1. It was during a consult with a Qlik employee at the World Conference in Orlando. It was within the context of chart performance in the ajax client.
 I load variables (constants and expressions) using a text file. He said that I should define the variables without using a "=". I haven't throughly tested it yet, but the expressions don't seem to work if you don't have the "=".
 2. Do you know if the same applies to PICK statements as to IF statements? We have a scenario where we're using those to select between a 5 options for how to calculate a specific field in the chart… if it's calculating all 5 options each time, that could obviously be a pretty big performance hit!
 3. Hi Rob
 As interesting as usual. Just a question, i use the pick() function when there are more than one expression, does it performs like an if, or just evaluates the "picked" expression?
 1. Pick performs just like an if(). That is, all expressions are evaluated and then the pick() is applied to select a result.
 4. Hello Rob,
 this is pretty interesting, but a little bit disturbing, at least for me.
 your definition of 'short circuit' doesn't match with these ones
 you said that qlikview will calculate both sums before to evaluate condition, also with a pick, as you wrote in a comment above.
 if this is true, this is a not really good feature for qlikview.
 Is there any kind of official doc about this from QlikTech?
 Thank you very much for your blog, I enjoy it a lot.
 Best regards
 5. Alberto,
 Actually, the lack of short circuiting is not always bad. In this thread read Henric's explanation of why they don't short circuit (about half way down the thread). In most cases it's a good thing. It only becomes a potential negative when testing a variable (vs a row by row condition) and even then is only noticeable in large apps.
 6. Hello Rob,
 Is it still true that false branches are not terminated? I have made different attempts to test this (11.2 SR6), but I can not verify it. Instead it seems like the following expressions get the same calculation time (SEK selected in SelectedCurrency):
 compared to
 (I would however anyway write this expression differently)
 7. I'm not aware of any changes to the eval logic. I did some recent testing and it appeared that all branches were evaluated. I should clarify that I have no way of knowing for sure what was actually executed, but I speculate based on timing tests as you do.
 I'm not sure why your test shows the same calc time. It could be your testing methodology or it could be something else I'm missing.
 8. I have a nested-if for a formatted Income Statement report that performs decently, but it's not ideal. Since the chart can have a blank line (for formatting purposes), an Earnings Per Share line (which is formatted differently – out to 3 decimals), and then all other lines formatted normally, the approach below is the only way I've thought to handle this. Is there any way around a nested-if in this case?
 if([Level] = 'Space',' ', // Blank Line
 if([Level] = 'EPS',$(eEPS(Actual)), // EPS
 if([Calculation]='Total', num(sum(-[Actual]*[Amount])/vDivideBy,'$#,##0;($#,##0)'),
 9. Mark,
 This is actually a very good use of if(). At some row of the chart, each condition of the expression will be true. This is a situation where QV's lack of "short circuit" is actually advantageous.
 The issue discussed in this post applies when only one condition could be true. Your if() statement looks fine to me.
 10. if condition are in which level gives good performance in script level are expression level?
 can any one help me.

Researchers at Osaka University have developed a light-driven process for oxidizing polypropylene (PP), a widely used plastic, without creating waste.
The process uses a reactive chlorine dioxide radical to make the plastic reactive. PP is normally an unreactive material; however, the researchers made a highly reactive radical by mixing sodium chlorite and hydrochloric acid. The radical was then photochemically activated using an LED lamp as the light source.

Take the 2-minute tour ×
Let $n$ be a natural number, and consider the discrete cube $2^{[n]} := \{ A: A \subset \{1,\ldots,n\}\}$ consisting of all subsets of the $n$-element set $[n] := \{1,\ldots,n\}$. Define a downset in $2^{[n]}$ to be a collection ${\mathcal D}$ of elements $A$ in $2^{[n]}$ with the property that if $A \in {\mathcal D}$ and $B \subset A$, then $B \in {\mathcal D}$.
My question is: what are the largest and smallest possible values for the alternating sum $\sum_{A \in {\mathcal D}} (-1)^{|A|}$, as ${\mathcal D}$ ranges over downsets in $2^{[n]}$, as a function of $n$? (Here $|A|$ denotes the cardinality of $A$.)
The trivial bounds here are $\pm 2^{n-1}$, by taking only the positive or negative values of ${\mathcal D}$, but of course these values are attained on a "checkerboard" set which is very far from being a downset, and this suggests that significant improvement is possible.
By taking ${\mathcal D}$ to be the set of all subsets $A$ of $2^{[n]}$ of cardinality at most $r$ for some $1 \leq r \leq n-1$, this gives a value of $(-1)^r \binom{n-1}{r}$; setting $r$ close to $(n-1)/2$ then seems to give reasonably good extremals (of size about $2^n/\sqrt{n}$ asymptotically). In the spirit of Sperner's lemma, one might tentatively conjecture that these are the extremal examples, but I was unable to prove or disprove this. (I feel like I'm missing some obvious application of downset isoperimetric inequalities or something.)
One motivation for this question is from analytic number theory: partial divisor sums $\sum_{d|a: d \leq x} \mu(d)$ of the Mobius function (which show up from time to time in this subject) can be viewed as an alternating sum over a downset, where $n$ is the number of prime factors $p_1,\ldots,p_n$ of $a$, and ${\mathcal D}$ is the collection of subsets $A$ of $[n]$ for which $\prod_{i \in A} p_i \leq x$. So any bounds on the general alternating-sum-of-downset problem would imply bounds on partial divisor sums of the Mobius function that depend only on the number of prime factors.
One small observation (using the shifting technology of Frankl) which may or may not be of use: given two natural numbers $1 \leq i < j \leq n$ and a downset ${\mathcal D}$, define the $ij$-shift of ${\mathcal D}$ to be the set formed by replacing any element of ${\mathcal D}$ of the form $A \cup \{j\}$ with $A \cup \{i\}$, if $A$ is disjoint from $\{i,j\}$ and $A \cup \{i\}$ is not already in A. Note that this is again a downset. Call a downset ${\mathcal D}$ shift-minimal if it is equal to all of its $ij$-shifts. Then one can reduce without loss of generality to the shift-minimal case, because shifting does not affect the sum $\sum_{A \in {\mathcal D}} (-1)^{|A|}$. In other contexts, the reduction to the shift-minimal case can be very powerful, but for some strange reason I was unable to exploit it here.

_USER_: That does indeed look relevant, in particular the paper of Sagan-Yeh-Ziegler mentioned in David's answer seems to settle the question (at least for the absolute value of the alternating sum) in the case when the downset is an order ideal. It looks like there is now some serious evidence for the tentative conjecture stated above... – Terry Tao Jul 9 '12 at 17:41
_USER_ It looks to me like the definition of a downset is the same as an order ideal. What am I missing? – David Speyer Jul 9 '12 at 19:39
Ah, yes on reading that paper they are using the term "lower order ideal" synonymously with "downset". (In the lattice theory literature, "order ideal" often also requires closure with respect to join, see e.g. _URL_(order_theory), but that would make the concept trivial in the context of subsets of the cube.) – Terry Tao Jul 9 '12 at 20:06
... huh, it seems I was incorrect on that point: the notion of an "order ideal" is distinct from that of an "order-theoretic ideal"! A bit confusing (and all the more reason to use the terminology "downset", in my opinion...) – Terry Tao Jul 9 '12 at 20:29

Thanks for all the very quick responses,they were incredibly useful! Based on these responses, I think the conjecture is now settled in the affirmative, as follows.
For each n, let $F_-(n)$ and $F_+(n)$ be the minimal and maximal values of $\sum_{A \in {\mathcal D}} (-1)^{|A|}$ respectively. The conjecture is that $F_-(n), F_+(n)$ are the extremal values of $(-1)^r \binom{n-1}{r}$ for $r=0,\ldots,n-1$. More explicitly,
$$ F_-(n) = -\binom{n-1}{n/2}, F_+(n) = \binom{n-1}{n/2}$$
when $n$ is even,
$$ F_-(n) = -\binom{n-1}{(n-1)/2}, F_+(n) = \binom{n-1}{(n+1)/2}$$
when $n=3 \mod 4$, and
$$ F_-(n) = -\binom{n-1}{(n+1)/2}, F_+(n) = \binom{n-1}{(n-1)/2}$$
when $n=1 \mod 4$. As mentioned in the post, these bounds would be best possible.
By slicing an n-dimensional downset into two n-1-dimensional downsets, one obtains the inequalities
$$ F_-(n-1)-F_+(n-1) \leq F_-(n) \leq F_+(n) \leq F_+(n-1) - F_-(n-1)$$
which already gives most of the conjecture by induction and Pascal's identity; the only remaining cases that need separate verification are
$$F_+(n) = \binom{n-1}{(n+1)/2} \qquad (1)$$
when n is 3 mod 4, and
$$F_-(n) = -\binom{n-1}{(n+1)/2} \qquad (2)$$
when n is 1 mod 4.
Let's show (1), as the proof of (2) is similar. Fix n equal to 3 mod 4, and let ${\mathcal D}$ be a downset which attains the maximal value $F_+(n)$ of $\sum_{A \in {\mathcal D}} (-1)^{|A|}$:
$$ \sum_{A \in {\mathcal D}} (-1)^{|A|} = F_+(n).$$
Now introduce the "f-vector" $(f_0,\ldots,f_n)$ of $A$, with $f_i := |\{ A \in {\mathcal D}: |A|=i\}|$ defined as the number of elements of ${\mathcal D}$ of cardinality $i$. (This is shifted by one from the polytope conventions, I guess because i points determine an i-1-dimensional simplex.) Then we have
$$ f_0 - f_1 + \ldots - f_n = F_+(n).$$
Let r be the largest index for which $f_r$ is non-zero, or equivalently the largest cardinality of an element of ${\mathcal D}$. (We can treat the degenerate case when ${\mathcal D}$ is empty by hand.) If $r$ was odd, we could simply remove all $r$-element sets from ${\mathcal D}$ and increase the alternating sum, so we may assume that $r$ is even, so the alternating sum looks like $f_0 - f_1 + \ldots - f_{r-1} + f_r

In the Illusion of Sex, two faces are perceived as male and female. However, both faces are actually versions of the same androgynous face. One face was created by increasing the contrast of the androgynous face, while the other face was created by decreasing the contrast. The face with more contrast is perceived as female, while the face with less contrast is perceived as male. The Illusion of Sex demonstrates that contrast is an important cue for perceiving the sex of a face, with greater contrast appearing feminine, and lesser contrast appearing masculine.

Project Will Bring Reclaimed Water to Clearwater Residents
A project funded by the Southwest Florida Water Management District and the City of Clearwater will bring reclaimed water to residents who live in the Skycrest area of Clearwater.
The project includes the design and construction of a high-service pump station, more than 63,500 linear feet of reclaimed water transmission lines, distribution piping, and a five-million-gallon storage tank.
The project will interconnect reclaimed water supplies from the city's three waste water treatment plants, which will provide the ability to move reclaimed water to areas of high demand, and provide for the pumping and storage necessary to service additional customers in central Clearwater.
This project is expected to provide approximately 410,000 gallons per day (gpd) of reclaimed water to nearly 500 residential and commercial reclaimed water customers in central Clearwater. The project will offset 250,000 gpd of groundwater.
This cooperatively funded effort between the District's Pinellas-Anclote River Basin Board and Clearwater is estimated to cost $10.8 million. The District will contribute 50 percent of the costs.
Construction is scheduled to begin in May 2008 and is expected to be complete by December 2010.
Reclaimed water is wastewater that has received at least secondary treatment and is used for a beneficial purpose, such as irrigation. By offsetting demand for ground water and surface water, this alternative, non-traditional water source reduces stress on environmental systems, provides economic benefits by delaying costly water system expansions, and eliminates the need to discharge wastewater effluent to surface waters.

Value Changes During Conversions
A conversion from a value type stores a copy of the source value in the destination of the conversion. However, this copy is not an exact image of the source value. The destination data type stores values differently, and even the value being represented might change, depending on the kind of conversion being performed.
Changes During Widening and Narrowing Conversions
Narrowing conversions change the destination copy of the source value, with potential information loss. For example, a fractional value is rounded when converted to an integral type, and a numeric type being converted to Boolean is reduced to either True or False.
Widening conversions preserve the source value but can change its representation. This happens if you convert from an integral type to Decimal, or from Char to String.
The original source value is not changed as a result of a conversion.
Changes During Reference Type Conversions
A conversion from a reference type copies only the pointer to the value. The value itself is neither copied nor changed in any way. The only thing that can change is the data type of the variable holding the pointer. In the following example, the data type is converted from the derived class to its base class, but the object that both variables now point to is unchanged.
' Assume class cSquare inherits from class cShape. Dim shape As cShape Dim square As cSquare = New cSquare'The following statement performs a widening'conversion from a derived class to its base class. shape = square

Terminology as a set of concept carriers crystallizes our special knowledge about a subject. Automatic term recognition (ATR) plays a critical role in the processing and management of various kinds of information, knowledge and documents, e.g., knowledge acquisition via text mining. Measuring termhood properly is one of the core issues involved in ATR. This article presents a novel approach to termhood measurement for mono-word terms via corpus comparison, which quantifies the termhood of a term candidate as its rank difference in a domain and a background corpus. Our ATR experiments to identify legal terms in Hong Kong (HK) legal texts with the British National Corpus (BNC) as background corpus provide evidence to confirm the validity and effectiveness of this approach. Without any prior knowledge and ad hoc heuristics, it achieves a precision of 97.0% on the top 1000 candidates and a precision of 96.1% on the top 10% candidates that are most highly ranked by the termhood measure, illustrating a state-of-the-art performance on mono-word ATR in the field.

day liveaboard safari through this region. These trips stop at all the best dive sites - usually offering three to four tanks per day, and include multiple shore excursions.
Eleuthera, Exumas and Cat Island diving seasons and weather
Like the rest of the region, these islands enjoy a tropical savannah climate with warm days, clear skies, and less humidity than the southern Caribbean. You can expect sunny afternoons and daytime temperatures between 25 and 32°C no matter when you plan to visit. During the Bahamas' mild winter between November and April, nights can become quite brisk, with temperatures dropping to 18°C and occasionally below. Then, from June to October, the rainy season brings warmer temperatures and a few days of precipitation per month.
The Bahamas are frequently impacted by hurricanes and tropical storms between June and November, with a peak in storm risk during August and September. During these months, passing storms can create rough surface conditions and poor visibility - even if they don't make landfall. Eleuthera, the Exumas, and Cat Island have far less protection than larger islands in the archipelago - like Nassau, making them particularly prone to flooding and storm surge.
Busy season runs from November through May, with two main peaks in tourism - Christmas and New Year holidays, and Spring Break. Dive here during summer months like May and June or between storm season and the holiday rush in November for uncrowded sites.
The Bahamas boast good visibility all year round, with 25 to 30 metres on most days. Water temperatures fluctuate dramatically by month, dipping as low as 22°C in January and reaching nearly 30°C in August. Depending on the timing of your trip, you may want to dive in a thin rash guard or skin, 3mm, or even 5mm wetsuit.
The Exuma Cays Land and Sea park was one of the region's first marine preserved areas, enjoying strict protection since 1958. Further initiatives in the region and the Bahamas' new nationwide environmental efforts also benefit this region tremendously, capping development and keeping the islands pristine.
In 2008, this unprecedented, region-wide collaboration called the Caribbean Challenge Initiative (CCI) was launched. This programme joins countries across the Caribbean in a voluntary commitment to protect and effectively manage at least 20% of their nearshore marine environment by 2020. So far, the effort has led to 15 new marine protected areas and three expanded areas, comprising over 11 million newly protected acres.
Other local efforts include developing sustainable fisheries, protecting Bahamanian coral reefs, and promoting environmentally responsible tourism. NGOs like The Nature Conservancy, Bahamas Reef Environment Educational Foundation, and the Bahamas National Trust are leading the charge. Additionally, more and more resorts and dive centres are joining the fight by banning single-use plastics, promoting reef-safe products, and upholding high environmental standards in their operations.
If you're hoping to get involved with conservation or citizen science during your time on the islands, you're in luck! Eleuthera, the Exumas and Cat Island are home to multiple marine institutes, coral reef restoration projects, sea turtle sanctuaries, and environmental conservation efforts that accept volunteers.

NUTRIENT-RICH PORK: PART OF HEALTHY EATING PATTERNSIn the market place today, lean, nutrient-rich pork is versatile, affordable and accessible. Pork has many beneficial qualities to make pork easy to incorporate into any healthy andbalanced diet.
Source of Key Nutrients: Pork is both a good source of protein and also provides several important vitamins and minerals. A 3-ounce serving of pork is an "excellent" source of thiamin, selenium, protein, niacin, vitamin B6 and phosphorus, and a "good" source of riboflavin, zinc, and potassium.
Lean Protein: Today's pork is 16% leaner and 27% lower in saturated fat compared to20 years ago. Seven cuts of pork meet the USDA guidelines for "lean" by containing less than 10 grams of fat, 4.5 grams of saturated fat and 95 milligrams of cholesterol per 100 grams of meat. Popular pork tenderloin has the same amount of fat as a skinless chicken breast.
Heart-Healthy: Pork is naturally low in sodium and a "good" source of potassium – two nutrients that, when coupled, can help regulate blood pressure. Pork tenderloin is certified as heart-healthy by the American Heart Association with its heart-check mark, indicating that it contains less than 6.5 grams of fat, 1 gram or less of saturated fat (and 15% or less calories from saturated fat) and 480 milligrams or less of sodium per label serving, among other criteria.

s = pp, ps,i = 0. This can be understood from the similarity between the integral expression of \({C}_{{{p}}_{\rm{i}},{\ell }_{\rm{i}}}^{\,{p}_{\rm{s}},{\ell }_{\rm{s}}}\) and the orthogonality relationship of LG modes. The fidelity \({{{\mathcal{F}}}}=| \mathop{\sum }\nolimits_{{p}_{\rm{i}}}^{{p}_{\rm{s}}}{{C}^{* }}_{{p}_{\rm{i}},0}^{{p}_{\rm{s}},{\ell }_{p}}{C^{\rm{th}}}_{{p}_{\rm{i}},0}^{{p}_{\rm{s}},{\ell }_{\rm{p}}}{| }^{2}\) was evaluated within the considered subspaces (where indices pi,s are bounded from 0 to 10 and i = 0, s = p), where \({{C}^{* }}_{{p}_{\rm{i}},0}^{{p}_{\rm{s}},{\ell }_{\rm{p}}}\) represents the measured coefficients and \({{C}^{th}}_{{p}_{\rm{i}},0}^{{p}_{\rm{s}},{\ell }_{\rm{p}}}\) represents those expected from the thin-crystal approximation—both of the coefficients are obtained after normalizing the state in the reduced subspace.
In this approximation, the parity of the spatial modes is also conserved35. This effect can be highlighted by considering pump beams in HG modes38 which, on the crystal plane, read
$$\begin{array}{l}{\rm{H{G}}}_{{m}_{\rm{p}},{n}_{\rm{p}}}\left(x,y\right):= \left\langle x,y| {m}_{\rm{p}},{n}_{\rm{p}}\right\rangle\\ \propto \exp \Big(-\left({x}^{2}+{y}^{2}\right)/{w}_{\rm{p}}^{2}\Big){h}_{{m}_{\rm{p}}}\left(x/{w}_{\rm{p}}\right){h}_{{n}_{\rm{p}}}\left(\,y/{w}_{\rm{p}}\right),\end{array}$$
where hm(x) represents Hermite polynomials of order m. HG modes form a complete, orthonormal set with even or odd functions along the x- or y-directions; the SPDC state can therefore be decomposed as \(\left\vert {{\Psi }}\right\rangle =\mathop{\sum }\nolimits_{{m}_{i},{n}_{i}}^{{m}_{s},{n}_{s}}{K}_{{m}_{i},{n}_{i}}^{\,{m}_{s},{n}_{s}}\left\vert {m}_{i},{n}_{i}\right\rangle \otimes \left\vert {m}_{s},{n}_{s}\right\rangle\). This basis has been extensively studied35,36,43 and recently considered for biphoton super-resolution measurements44. When studying the SPDC correlations on the basis of HG modes (chosen with the same waist parameter w = wp of the pump), one has the conservation laws: \({n}_{\rm{p}}={{{\rm{mod}}}}({n}_{i}+{n}_{s},2)\) and \({m}_{\rm{p}}={{{\rm{mod}}}}({m}_{\rm{i}}+{m}_{\rm{s}},2)\), as can be directly inferred from the parity of the integrands appearing in the expression of \({K}_{{m}_{\rm{i}},{n}_{\rm{i}}}^{{m}_{\rm{s}},{n}_{\rm{s}}}\) (see Methods and ref. 35 for a detailed proof). Figure 5 shows calculated HG mode correlations for different states (with reconstructed biphoton amplitude and phase shown in the insets). The results show an excellent agreement with theory; in particular, the parity conservation is evident from the chessboard-like correlation patterns.
Fig. 5: Hermite–Gauss correlations.
figure 5
When pumping the crystal with \({{{{\mathcal{E}}}}}_{\rm{p}}(x,y)={{{{\rm{HG}}}}}_{m,n}(x,y)\), we observe biphoton correlations in the basis of HG modes that highlight the parity conservation of the SPDC process. Insets show the reconstructed biphoton fields from which the correlations have been extracted. Upon each plot, the fidelity between the retrieved field and the theoretical one in the thin-crystal approximation is reported. The error analysis is discussed in Methods.
Finally, Fig. 6 demonstrates an example of the potential applications of biphoton digital holography. The unknown pump beam can carry information about an image or be scattered by a three-dimensional object. The information about the scatterer is transferred to the SPDC state and can be retrieved through our technique (Fig. 6b). We show this in the case of off-axis holography, which can present limitations for complex structures due to the limited camera resolution. These limitations are not related to our proposal and can be improved by employing other approaches, for example, on-axis phase-shifting digital holography9.

Conclusion
In this work we introduced a novel approach for reconstructing the spatial structure of correlated two photons states. Our proposal exploits the coherent superposition of two SPDC states and the possibility of imaging the amplitude of this superposition with a time-stamping camera. The experimental results showed how, from a single measurement, it is possible to retrieve, in post-processing, a large amount of information about a two-photon spatial state, including correlations in different degrees of freedom, entanglement and spatial mode decomposition in arbitrary bases. We focused on the simple case of SPDC generated from thin crystals and, for different pump fields, analysed OAM and parity conservation, high-dimensional entangled states and radial mode correlations. The results show the superiority of this technique, compared with projective techniques (for example, the ones in refs. 34,42,45), in the context of benchmarking highly correlated quantum states. We observe that, if a projective measurement was performed on a 11 × 11 subspace, in line with the ones considered in this work for radial modes, several days would be required to accumulate the necessary statistics on 1212 projections due to the low count rates associated with the lossy techniques used for mode projection. In comparison, our approach allows us to obtain the necessary data in a few minutes, independently from the dimensionality of the subspace to be analysed (the latter is only limited by the camera resolution). We also note that, with the time-stamping camera, when spatial correlations are present, a further background subtraction is possible thus improving the signal-to-noise ratio of this kind of measurement. We thus achieved a three-order-of-magnitude enhancement on the reconstruction time with high fidelities for the biphoton states, obtaining an average fidelity equal to 87%. The lowest fidelity values are due to imperfect pump preparations or an undesired spatially varying phase in the reference beam and not to intrinsic
