Functions commonly have multi-character names - mainly acronyms - in cryptography, much more so than in math. The question is how we can best format these methods in LaTeX? If we don't do anything then they seem to consist of multiple symbols (indicating, perhaps, multiplication) in italics.
For example $KDF$ will look like three separate characters, K, D and F (in a different font of course).
The \operatorname command works well for this purpose, and I think it's the most appropriate choice. It disables italics, prevents hyphens from being converted into minus signs, and more.
Example: HMAC-SHA256(k, m) can be typeset using $\operatorname{HMAC-SHA256}(k,m)$.
screenshot of example
Unfortunately, \operatorname is a lot to type. Usually, a document would use \DeclareMathOperator once at the beginning to define shorter command names for common operators. This actually works on Crypto SE:
Now $\hmac(k,m)$ will be rendered just like $\operatorname{HMAC}(k,m)$.
The first line defines a new command \hmac, and the second line uses it.
This might be worthwhile if you're writing a long answer, but it seems like overkill in most cases. Maybe Crypto SE could eventually declare some popular operators automatically?
Even without \DeclareMathOperator, there are still some shorter options. I think the semantics of these commands are less appropriate, but that's not the end of the world.
 - \text: Does not space things out as nicely as \operatorname does.
 - \mathrm: Does not handle hyphens properly, so HMAC-SHA256 is rendered as "HMAC minus SHA256". Same spacing problem as \text.
Personally, I've been using \text on Crypto SE. That's out of laziness: I think \operatorname (or declaring a custom operator command) is a better choice.
 - $\begingroup$ Been abusing \text too… thanks for the pointer towards \operatorname which indeed seems to be a better fit. $\endgroup$ – e-sushi Feb 16 '16 at 23:29
 - $\begingroup$ I presume we cannot use \DeclareMathOperator on Crypto.SE with all the small snippets of LaTeX? $\endgroup$ – Maarten Bodewes Feb 21 '16 at 14:38
 - $\begingroup$ _USER_ I added some details on that $\endgroup$ – Tim McLean Feb 22 '16 at 2:43

Step 6: Mount the Servos, Battery, and Arduino
Picture of Mount the Servos, Battery, and Arduino
Zip ties are used to mount the various electronic components.
The motors were attached to the mounting plate first by using some rubber cement (optional) to keep them in place, and wrapping and tightening them as much as possible with the zip ties.
Note that most of the ties thread through the space between the mounting plate and the shoe. As my zip ties weren't long enough in some areas, I combined two together. After the servos were in place, I trimmed down the ties.
Beneath the motors, the battery case is mounted in much the same way, power switch outward.
Finally, the Arduino board can be attached. The holes line up with zip ties on both side, and is held in place by screws attached to them.
Before attaching the Motor shield, some modifications must be made.

Potassium Hydroxide KOH Caustic Potash | 2 lbs
Potassium Hydroxide, Caustic Potash (KOH) High Quality Flakes, Food Grade & Kosher from North America
What is Potassium Hydroxide?
Potassium hydroxide is an inorganic compound, commonly called by its chemical formula designation KOH or caustic potash. Along with sodium hydroxide, this colorless solid is a prototypical strong base. It has many industrial and niche applications, most of which exploit its corrosive nature and its reactivity toward acids.
Can Potassium Hydroxide be used for soaps?
The saponification of fats with KOH is used to prepare "potassium soaps," which are softer than the more common sodium hydroxide-derived soaps. Because of their softness and greater solubility, potassium soaps require less water to liquefy, and can contain more cleaning agent than liquefied sodium soaps.
Is this Potassium hydroxide allowed for food and electronic manufacturing?
Yes in food products, potassium hydroxide acts as a food thickener, pH control agent and food stabilizer. KOH is also used for semiconductor chip fabrication.
Is Ingredient Depot's Potassium Hydroxide Kosher certified?
Yes, our Potassium hydroxide is Kosher tested and certified from our manufacturer.
In what country is this KOH manufactured?
Our Potassium Hydroxide is manufactured in North America.

GSOA Hopes to Drive Space Sustainability With New Code of Conduct
The Global Satellite Operators Association (GSOA) hopes to play a key role and drive better behaviors in the area of space sustainability. GSOA released a Code of Conduct on Space Sustainability on Nov. 13 — calling on operators to implement responsible practices that mitigate the risk of in-orbit collision, minimize the threat of non-trackable debris, protect humans in space and limit effects on optical astronomy. It is a major new initiative.
As the only CEO-driven satellite association in the world, GSOA – a global industry organization representing over 70 members, with satellite operators in all orbits, launchers, suppliers and partners – aims to take the lead in addressing global challenges, seizing opportunities, and providing a unified voice for the satellite industry. Satellite connectivity can significantly help reduce today's digital divide, as the number of satellite broadband users is set to double to at least 500 million people by 2030, according to GSOA.
"Satellites in all orbits deliver vital satellite connectivity and high throughput broadband services. While they offer great promises in bridging the digital divide, they must be launched, deployed, operated and disposed of in a responsible manner," Isabelle Mauro, the director general of GSOA, said in a statement.

What is the goal of politics and politicians?
The goal of politics is to exercise, achieve and apply power and authority.
Politics can be used by many entities such as government, individuals and organizations.
The goals of politics can be numerous and often diffuse:
 - Lower-level management can use politics to get higher incentives and wages for themselves.
 - Supervisors can exercise their power and authority to get the required results from their immediate subordinates and lower-level employees.
 - Some people use politics negatively to obtain a certain social position, status, wealth and success.
 - Others can obtain authority and power as a part of their position in society such as mayors, presidents, supervisors or bosses etc.
Therefore, we could say that the goal of politics is always about achieving or using power for an individual's or a group's advantage.
However, the goals of politics and politicians are not always as cynical as they sometimes seem. Politics can also be used to achieve positive outcomes - such as increasing the productivity of a nation, increasing team-work, and the implementation of projects and tasks.

What is the source and goal of politics?
 - Politics: Applied authority in order to influence a chosen support group in order to push an agenda.
 - From high school to adulthood, we function in a society with competing agendas and there is only so much room at the top.
 - In order to achieve the top positions, politics come into play. Just think about who gets selected for promotion? They are not always the best candidate, but the person whom the boss thinks is the best.
Why did the boss choose person A over person B? The answer is because the selected person is the best political fit in order to keep the current culture going. That is politics.
The person at the top chooses, the staff supports, and in order to get into that political culture you have to play the boss's game and make him/her happy. This is true of almost every aspect of life, unfortunately.

Cattail: Learn how to harvest and utilize this wild aquatic plant during the best and worst of times
(NaturalNews) One of the most common wild plants found throughout the world, cattail, is astoundingly versatile. So much so that it can make the difference between life and death if one is lost in the wilderness or when food is in short supply. But this humble plant is also extremely handy in ordinary, day-to-day situations too. If you have access to an area with cattail, an exceptional survival resource is right at your fingertips.
Year-round usefulness
Most of us have come across cattail at one time or another. Distinguished by a brown cigar-shaped head on a hearty stalk, cattail grows in wet areas often close to streams, ponds and lakes. As one of the most functional wild plants, cattail offers different uses during each season.
Early spring - Fresh shoots begin to sprout and can be dug up and (once peeled) eaten raw or sauteed. Additionally, the lower part of the leaves can be added to salads.
Summer - This is the season when the uses for cattail are most abundant. Once a stem is pulled from the ground, you will notice the lower part is white. When eaten raw, it tastes similar to cucumber. Cooked, it tastes like corn. Lower cattail stalks are a good source of vitamins A, B and C along with potassium and phosphorus. During midsummer, a yellow pollen appears that can be used as flour or thickener for soups and stews. To harvest the pollen, bend the cattail head into a paper bag and shake. In late summer, green flower spikes appear and can be eaten like corn on the cob.
Autumn - The root of cattail can now be harvested. Wash thoroughly and submerge in water - let sit until a gel forms. Drain the gel and use for bread making and soups. For a protein-rich flour, dry the roots and grind. It can also be roasted and ground for a healthy coffee substitute.
Winter - In northern climates, cattail root is difficult to collect, but not impossible if you can break through frozen ground and ice. In late winter, new shoots begin to emerge, once again providing a food source.
Cattail also has many other uses. The brown, tight heads are often dry at the core (even after heavy rain) and can be used as survival tinder. Likewise, dipping the head in oil or fat will create a useable torch. Similar to down, the head yields a fluffy wool when broken apart and serves as excellent insulation for pillows, mattresses and clothing. If lost in the wilderness, a makeshift bed made with cattail down will help protect against heat loss, while the long leaves of the plant can be woven into mats and shelters. Medicinally, the gel found within the leaves act as a topical anesthetic. And a poultice made from the roots will soothe stings, burns and cuts.
Before trotting off to reap the benefits of cattail, a word of warning from Kat Morgenstern of Sacred Earth:
"Personally I do not harvest any roots or shoots in order to avoid negatively impacting next year's growth. The pollen and the cobs are by far the safest and easiest parts to collect. Furthermore, it requires some skill to distinguish young cattails from young Yellow Irises - which are poisonous, so unless you are an experienced forager and know how to distinguish these plants before their flowering parts appear, it may be better to leave those young plants alone.
"Last, but not least, cattail is said to have a certain emmenagogue action and should therefore be avoided during pregnancy."

Atmospheric corrosion of historical organ pipes: The influence of environment and materials
Artikel i vetenskaplig tidskrift, 2008
The corrosion of lead-rich pipes in historical organs in different parts of Europe has been investigated. The influence of the environment and the composition and microstructure of the pipe metal was studied. Pipe Corrosion was documented by visual inspection (boroscope). The corrosion attack and the composition and microstructure of the metal were characterized by OM, SEM, XRD, IC and FAAS. It is shown that the degree of corrosion of the pipes is correlated to the concentration of gaseous acetic and formic acid in the organ. The organic acids are emitted by the wood from which the wind system is built. It is also shown that pipe corrosion decreases with increasing tin content in the range 0-4% (wt). Possible conservation strategies are discussed. (c) 2008 Elsevier Ltd. All rights reserved.

Iterated integrals on elliptic and modular curves
Oxford Mathematician Ma Luo talks about his work on constructing iterated integrals, which generalizes usual integrals, to study elliptic and modular curves.
Usual integrals
Given a path $\gamma$ and a differential 1-form $\omega$ on a space $M$, we can parametrize the path $$\gamma:[0,1]\to M, \qquad t\mapsto\gamma(t)$$ and write $\omega$ as $f(t)dt$, then define the usual integral $$\int_\gamma \omega=\int_0^1 f(t)dt.$$ If we have two loops $\alpha$ and $\beta$ based at the same point $x$ on $M$, then $$\int_{\alpha\beta}\omega=\int_\alpha \omega+\int_\beta \omega=\int_{\beta\alpha} \omega.$$ The order of the loops from which we integrate does not affect the result. Therefore, the usual integral can only detect commutative, i.e. abelian, information in the fundamental group $\pi_1(M,x)$.
Iterated integrals
Kuo-Tsai Chen has discovered a generalization of the usual integral as follows: Given a path $\gamma$ and differential 1-forms $\omega_1,\cdots,\omega_r$ on $M$. Write each $\omega_j$ as $f_j(t)dt$ on the parametrized path $\gamma(t)$. Define an iterated integral by \begin{equation}\label{def} \int_\gamma \omega_1\cdots\omega_r=\idotsint\limits_{0\le t_1\le \cdots \le t_r\le 1} f_1(t_1)f_2(t_2)\cdots f_r(t_r) dt_1\cdots dt_r. \end{equation} It is a time ordered integral. Now for the two loops $\alpha$ and $\beta$, we have $$\int_{\alpha\beta}\omega_1\omega_2-\int_{\beta\alpha}\omega_1\omega_2= \begin{vmatrix} \int_\alpha\omega_1 & \int_\beta\omega_1\\ \int_\alpha\omega_2 & \int_\beta\omega_2 \end{vmatrix},$$ which is often nonzero. Therefore, iterated integrals are sensitive to the order, and they must capture some non-abelian information. But what kind of non-abelian information?
Differential equations and nilpotence
We can reformulate the definition of iterated integral as the element $y_r$ in the solution of a system of differential equations: \begin{align*} dy_0/dt &=0\\ dy_1/dt &=f_1\cdot y_0\\ dy_2/dt &=f_2\cdot y_1\\ \cdots & \\ dy_r/dt &=f_r\cdot y_{r-1} \end{align*} where we insist $y_0(t)\equiv 1$ so that $y_r$ agrees with our previous definition. The auxiliary functions $\{y_0,y_1,\cdots,y_{r-1}\}$ allow us to rewrite the system in the following way: $$ \frac{d}{dt}(y_0,y_1,\cdots,y_r)=(y_0,y_1,\cdots,y_r) \begin{pmatrix} 0 & f_1 & 0 & \cdots & 0 \\ 0 & 0 & f_2 & \ddots & \vdots \\ \vdots & \vdots & 0 & \ddots & 0 \\ \vdots & \vdots & \vdots & \ddots & f_r \\ 0 & 0 & 0 & \cdots & 0 \end{pmatrix} $$ where the matrix on the right is nilpotent (powers to 0). In general, the solutions to a system exist on a small scale for a short time locally. As the time progresses, the local information is being transferred globally. The global behaviour of the solutions is dictated by the system. In our case, iterated integrals are limited by the nilpotence property. Perhaps surprisingly, even with this limited non-abelian information, one finds they have interesting applications to number theory, most notably in Minyhong Kim's work, which uses $p$-adic iterated integrals (local) to help find rational points on curves (global).
Algebraic iterated integrals and beyond nilpotence
Elliptic curves and modular curves both feature prominently in the proof of Fermat's Last Theorem by Andrew Wiles and are extensively studied objects in number theory. My recent work (PhD thesis) constructs algebraic iterated integrals on elliptic curves and the modular curve (of level one). The construction proceeds in a similar fashion as iteratively solving the system of differential equations above. In the case of elliptic curves, my work is based on previous work of Levin--Racinet. The algebraic iterated integrals on elliptic curves lead naturally to elliptic polylogarithms, which generalizes classical polylogarithms \begin{align*} \mathrm{Li}_k(x):&=\sum_{n=1}^\infty\frac{x^n}{n^k},\qquad k\ge 1 \\ &=\int_0^x \frac{dz}{1-z}\underbrace{\frac{dz}{z}\cdots\frac{dz}{z}}_{(k-1)\text{ times}} \end{align*}
In the case of the modular curve, one needs to go beyond nilpotence, by adding some prescribed reductive (more complicated non-abelian) data, thereby constructing iterated integrals with coefficients. Specifically, algebraic iterated integrals of modular forms are constructed. They provide multiple modular values, which belong to a special class of numbers called periods. These periods appear not only in number theory, but also in quantum field theory, and in the study of motives. Francis Brown has proposed a framework where Galois theory of periods can be studied. Just as symmetries of algebraic numbers can be deduced from their defining equations, many relations between these periods result from structural properties of their defining iterated integrals. Our goal is to understand these structures and then connect them back to relations between periods.

Cross-correlation clarifies the relationships between PID control loops. With accurate measurement of process signals, loops can be compared against each other using a time-shift to identify those loops that are correlated. The resulting detail indicates whether one loop leads or lags another, and it enables production staff to quickly zoom in on the source of control loop performance issues.
PlantESP's correlation matrix graphically displays the many relationships on either a unit operation or plant-wide basis. Its use of color-coding provides a clear indication of leading loops that are upstream in the process (Red) versus lagging loops located downstream (Blue). PlantESP also specifies the timing of that relationship.
PlantESP makes it easy to switch from one advanced forensic tool to another. Control loops selected in the Cross-Correlation matrix can be evaluated in the Power Spectrum viewer with the touch of a button.

The MyProxy Service gives a means to store proxy certificates for later usage when, for instance, your private key is not at hand.
The procedure to store your proxy certificate exists both as a graphical Java-based tool and via the Globus command-line command.
The Java based GSISSH-Term can use a MyProxy server directly. Alternatively, when using the Globus Toolkit, users can retrieve their proxy certificate by using the Globus command-line.
Grid middleware uses certificates for authenticating and authorizing users. The use of certificates means that separate passwords for each account on each of the target machines are not required: instead, a user just needs to create a single certificate with a single password for their personal key. Then several services can be used with that certificate. For example, one can use gsissh to login to a DEISA machine and run there a GridFTP file transfer session or login to another machine connected to the DEISA network without the need to specify a password.
Personal certificates are obtained from a Certification Authority. Instructions to apply for a certificate usable in the DEISA infrastructure are provided by the Primer. A certificate consists of two parts: a private key and a public certificate. They can be in stored a single 'p12' format file or stored in 'pem' format within two separate files, namely userkey.pem and usercert.pem. Users can convert between these two formats, if necessary, using the openssl command (See DEISA Certificates FAQ). Further, a web browser can import and export p12 files.
The MyProxy service stores proxy certificates, where these certificates can be employed on your behalf without the need to have your private key and certificate files at hand. This is useful, for example, when you are using a computer which you do not normally use. A use case example: a researcher visits an Internet Cafe to check the status of their jobs.
Indeed, it is also best to avoid distributing the private key across several machines, but to keep it safe on your workstation instead. If you wish to run Globus commands on a platform on which you cannot or should not store your private key and/or certificates, then you can retrieve your proxy certificate stored at a MyProxy service. A use case example: A researcher needs to use ssh to login to a machine. On target machine they need to use Globus commands. Due to either security or practical reasons there is no private key stored on the target machine. So, the user can use Globus commands to fetch proxy certificate from a MyProxy server.

In Use or abuse we queried the meaning of 'significant' in the context of Paragraph 112 of the NPPF, which relates to the loss of agricultural land.
An inspector dealing with an appeal against the refusal of planning permission for 28 dwellings in Leicestershire has given us the answer (DCS Number 200-006-606).
"The proposed scheme would result in the loss of 2.58 hectares of grade 3 agricultural land to development" the inspector recorded. "Land within grade 1, 2 and 3a is defined in the glossary to the Framework as being the best and most versatile agricultural land. In preference to the development of this type of land the use of land of poorer quality is encouraged by paragraph 112 of the Framework. This government policy though relates to proposals involving the development of significant amounts of such land. The view of the Council, expressed in its Development Control Report on the application, is that the development of less than 20 hectares of such land is a low amount of land. I agree with that position."
So there we have it. 'Significant' in the context of Paragraph 112 of the NPPF means 20 hectares. For the time being.

text: This study investigated the influence of top-down and bottom-up information on speech perception in complex listening environments. Specifically, the effects of listening to different types of processed speech were examined on intelligibility and on simultaneous visual-motor performance. The goal was to extend the generalizability of results in speech perception to environments outside of the laboratory. The effect of bottom-up information was evaluated with natural, cell phone and synthetic speech. The effect of simultaneous tasks was evaluated with concurrent visual-motor and memory tasks. Earlier works on the perception of speech during simultaneous visual-motor tasks have shown inconsistent results (Choi, 2004; Strayer & Johnston, 2001). In the present experiments, two dual-task paradigms were constructed in order to mimic non-laboratory listening environments. In the first two experiments, an auditory word repetition task was the primary task and a visual-motor task was the secondary task. Participants were presented with different kinds of speech in a background of multi-speaker babble and were asked to repeat the last word of every sentence while doing the simultaneous tracking task. Word accuracy and visual-motor task performance were measured. Taken together, the results of Experiments 1 and 2 showed that the intelligibility of natural speech was better than synthetic speech and that synthetic speech was better perceived than cell phone speech. The visual-motor methodology was found to demonstrate independent and supplemental information and provided a better understanding of the entire speech perception process. Experiment 3 was conducted to determine whether the automaticity of the tasks (Schneider & Shiffrin, 1977) helped to explain the results of the first two experiments. It was found that cell phone speech allowed better simultaneous pursuit rotor performance only at low intelligibility levels when participants ignored the listening task. Also, simultaneous task performance improved dramatically for natural speech when intelligibility was good. Overall, it could be concluded that knowledge of intelligibility alone is insufficient to characterize processing of different speech sources. Additional measures such as attentional demands and performance of simultaneous tasks were also important in characterizing the perception of different kinds of speech in complex listening environments.

Definition of Archaeogenetics
Archaeogenetics: The study of the past using the techniques of molecular genetics. The application of genetics to archeology. The term "archaeogenetics" was coined in the 1990s by the archeologist Colin Renfrew from the Greek archaios (ancient) + genetics = archaeogenetics, literally, ancient genetics.
In archaeogenetics, information on the DNA of different ethnic groups from around the world is used to analyze prehistoric events and corroborate accounts from historical sources. The DNA data are reconciled with the findings of archeologists, linguists, and paleoanthropologists to shed light on the past.

Investigating Various Adder Architectures for Digital In-Memory Computing Using MAGIC-based Memristor Design StyleChandan Jha; Alireza Mahzoon; Rolf Drechsler
In: 6th International Conference on Emerging Electronics (ICEE). IEEE International Conference on Engineering and Emerging Technologies (ICEET), December 11-14, Bangalore, India, 2022.
Adders are implemented using a wide variety of architectures. These architectures have been extensively studied for digital IC-based implementations. In recent years, in-memory computing has gained interest owing to the benefits it provides in terms of both energy and performance as compared to conventional von Neumann computing. In this work, we for the first time investigate various adder architectures for in-memory computing using the memristor aided logic (MAGIC) design style for memristors. We analyze seven different adder architectures for bit-widths: 8-bit, 16-bit, 32-bit, and 64-bit. We have used the state-of-the-art SIMPLER tool for performing the mapping of these adders to memristor crossbars. We show that serial prefix adders are better suitable for IMC using the MAGIC design style as compared to the widely used ripple carry adder. The adder designs and the mapping will be made open source at _URL_ to promote further research in the direction.

Rare Maud Island Frogs Hatched In New Zealand [ScienceDaily 2008-03-05]

ScienceDaily (Mar. 5, 2008) — What looks at first to be a slimy mess in a Petri dish represents a highly-significant advance in conservation and restoration ecology.
Ecologists from both the Sanctuary and Victoria are celebrating the arrival of the first Maud Island frogs (Leiopelma pakeka) to hatch on mainland New Zealand for many years.
Clustered together to conserve moisture, the 13 fingernail-sized baby froglets were recently transferred from the Karori Sanctuary to Victoria University where they will be incubated and later released as young frogs.
No larger than a human adult's little fingernail, the Maud Island froglets differ from most frog species in that they hatch from the egg as fully-formed froglets without going through the usual tadpole stage.
13 froglets in total were found during a recent audit of a specially-constructed frog research enclosure at Karori Sanctuary.
"Sixty frogs were released into the special mouse-proof enclosure in 2006 in an effort to re-establish this highly-endangered species on the mainland," Victoria Master's student Kerri Lukis says. Ms Lukis is studying the Sanctuary population for her Master's thesis under the supervision of Associate Professor Ben Bell, Director of the University's Centre for Biodiversity and Ecological Restoration.
She says that thirty of frogs released in 2006 were later released outside of the enclosure so that the captive and wild populations could be compared. When it came time to find the frogs again to see how many frogs had survived and whether they had bred she was delighted to find the 13 froglets attached to adult males.
"This is extra special because Maud Island frogs have never been found breeding in their natural habitat before, and certainly not on the mainland.
"It's wonderful timing for 2008 - international Year of the Frog – and a Leap Year. It's rare to get a 'good news' story about frogs – every year around 35 species of frog become extinct and two of New Zealand's remaining native frog species are on the critical list."
While not the rarest species, the thimble-sized Maud Island frogs are nationally threatened. Like all of New Zealand's native frog species, they are endemic (found only here) and belong to the endemic genus Leiopelma.
They have evolved very little over the last 70 million years, resulting in some very distinctive features and behaviours. For example, they don't croak, live in water, have webbed feet, or go through a tadpole stage.
Associate Professor Ben Bell says the University and the Sanctuary have worked closely together on this project.
"It is good to know that the Karori Sanctuary frogs are able to breed in an enclosure there. Whether those frogs released into the wild in Karori survived and bred is less certain at present."

between the drawn figure and the given figure for Task 5. In the case of the task, following the rectangle, the error using GRIPIT was not significantly different with use of a conventional penholder as Fig. 11 shows. The p-value between GRIPIT and the conventional penholder, while following the square, was 0.087, so error from GRIPIT is mostly lower than the error from the conventional penholder. Moreover, statistical analysis of the data showed that there is no significant difference between drawing with a conventional penholder and drawing without any device while performing whole tasks.

The main reason for the results obtained for Tasks 4 and 5 seems to be solidity of hand posture. The writing accuracy of non-disabled people depends on many different factors, but for people with SCI it mainly depends on postural solidity because they cannot control their fingers. GRIPIT is able to fix the pen firmly to users' fingers via the tensioning system, whereas other writing devices cannot apply high fixation force to the pen. Task 6, which measures solidity, is discussed in detail in the next section.
Solidity performance
Experimental data analysis method
Solidity was measured for Task 6 by asking subjects to draw three horizontal lines and three vertical lines five times each. The ratio of applied force (F in Fig. 12) and the rotated angle of the pen (φ in Fig. 12) was used as an indicator of solidity [29, 30]. The system for simultaneously measuring force and position data is shown in Fig. 13a.
Fig. 12
Schematic draw for solidity definition. While drawing a line from O1 to O2, the pen rotates from line P1 to line P2. The solidity was defined as the ration of rotated angle of pen (φ) and applied torque (τ)
Fig. 13
Total system construction to measure force and position of the pen simultaneously a, experimental setup to measure the writing force and the position of markers b, and marker attachment points to measure the position of pen from a hand frame view c
We used a load cell to measure the force and motion capture system to measure the variation of the angle. The force measurement stage shown in Fig. 13b was constructed using a Nano17 (ATI, Apex, NC, USA), a writing plate, and a support plate. The six-axis load cell was attached under the writing plate to measure the writing force, which was defined as the friction force between the pen and the writing plate. The support plate, on which subjects could lean their arm, was attached parallel to the writing plate to exclude the arm weight from the writing force. Data were collected using a Single Board Rio and LabVIEW (National Instruments Corporation, Austin, TX, USA).
The Vicon system (Vicon, LA, USA), which detects the position of reflective markers with infrared light, was used to obtain information about the location of the pen and subjects' hand. Two markers (M1, M2, Fig. 13c) were attached to the pen to track its position, and three markers (M3–M5, Fig. 13c) were attached to the hand to create an x-axis, a y-axis, and an origin for the moving system frame. Eight Vicon cameras were used to measure the markers while performing the experiment. Each of the three cameras were placed on the left and right sides of the desk, one camera was placed on the top, and one on the front of the desk to continuously check the overall markers.
We used an analog output function from a Single Board Rio device for data synchronization. After the experiment, we collected the position data from nexus and force data from LabVIEW. Using the trigger signal in the force data, we synchronized the data and calculated the ratio between the angle variation and writing force.
Experimental data analysis result
The ratio of angle variation and writing force, which is the variable for solidity, was calculated using MATLAB, and the results are plotted in Fig. 14. Angle variation and force/angle ratio results for all subjects show that the writing performance of GRIPIT is significantly better than the performance obtained with other writing methods, when statistical analysis was performed. Moreover, statistical analysis of the data showed that there is no significant difference between drawing with a conventional penholder and drawing without any device while performing whole tasks. A large value for the force/angle ratio means that users can write without their hands shaking, even when they apply high force to the pen.

(p < 0.05)
We developed GRIPIT to assist SCI people to make tripod grasp for them to go back to occupation or school because this grasp is suitable to make stable grasp force and moment balance while grasping small objects or various pen. The device is designed to be compact, lightweight, and simple by using the underactuated tendon-driven mechanism and the tension-maintenance winder. After the device development, we devised new assessments to measure writing ability from various viewpoints including both qualitative and quantitative methods, while most conventional assessments include only qualitative methods or simple time measuring assessments. Qualitative assessment results show that GRIPIT is more complicated to wear and use than conventional writing assist devices. Experimental participants reported that process of using GRIPIT, consisting of wearing a glove, fixing a glove, inserting a pen, pulling a wire, and manipulating the tension maintaining part, is more complicated than the process of a conventional penholder that consists of fixing a pen into a hole and attaching the splint to the body. However, responders claimed writing with GRIPIT is preferred because it improves the sensation of writing, fatigability, and legibility because it applies a high fixation force to the pen and compensates torque generated by contact forces. Quantitative measurements of writing accuracy and solidity of hand posture show that GRIPIT yields better results than other methods. Writing with a conventional penholder and handwriting show similar results, which means that a conventional penholder is not that useful compared to the handwriting. However, GRIPIT assists users to write accurately without shake of the pen even high force is applied on the pen as the evaluation results show. We believe that reducing the shake of the pen while writing is the most important factor for people with SCI because they cannot use their fingers to control the pen and have to use their arm due to their paralyzed fingers. This factor also attributes writing with GRIPIT to get better results in the total evaluations because GRIPIT assists users to apply sufficient grasp force and form tripod grasp to get high resistance in the torque applied by pentip force.
This study has two major limitations in terms of device development and writing assessment. Although we developed device to assist grasp using a single wire for convenience, tension-maintenance winder requires several kinds of process to prepare grasp and makes the using process complicate according to the interview from the qualitative assessment. Although subjects can wear and use GRIPIT alone, they insisted that it would be more useful if the process of using GRIPIT was simplified. The device will be improved using motor or other tension-maintenance mechanism for the future works. Another limitation of this study, which is concerned with assessment, is a limited sample size; nevertheless, this study should suffice to notify GRIPIT assist users to write better than using other devices and the assessment method is useful for writing evaluation. More experiments with improved GRIPIT using motor or other tension-maintenance mechanism should be considered in future studies.
We developed a glove-type assist device named GRIPIT to assist people with SCI to better use their hands. GRIPIT helps people to grasp tools by using manual actuation to apply force to the fingers via a single wire. In contrast, conventional assist devices only fix tools to the hand by fitting them into a hole on the device and then attaching the device to the hand with Velcro. GRIPIT also has a simpler design and an easier actuation method than other exoskeleton robots, because it consists of only a single glove and a single wire.
GRIPIT has a high potential to increase quality of life for people with hand paralysis because it can help users to grasp a range of tools, whereas conventional devices can accept only the products that fit into their hole. Moreover, GRIPIT can be easily extended to form other grasp postures by changing the routing points of its wire. GRIPIT can be extended to assist most of the hand functions required in daily life by designing new forms of its glove for various grasp postures and by improving its wearability and ease of use.

What Can We Know about the Role of Women in Ancient Israel? by Carol Meyers
People lived in households. Most people were agrarians, agriculturalists, farmers, and the economic, political, religious, social aspects of life were all primarily in the household but for both men and women. What archeologists have discovered in some really wonderful, careful excavations in the past couple decades is the assortment of artifacts that appear in different spatial parts of a dwelling.
And in a sense to the great surprise of many investigators, there were spaces in the household in which the implements of food preparation and consumption, that is where food was prepared and eaten, are found in the same physical space as small objects having to do with religious practices, with religious rituals, which leads us to the belief that ritual was part of meals, of household meals. And we do know by using biblical texts and other ancient near eastern texts and iconography that women were responsible for most of the transformation of agricultural products into something that you could eat or drink.

They baked the bread, and they prepared the stews and so on. So that linking women's practices of food preparation with the ritual objects that are found in the same spaces and households gives us an idea that women were intrinsically involved in household religious practice. Now, even though the Bible focuses on national or communal religious practice—sacrifices at shrines in the temple, the tabernacle—those were large in the Bible, but in terms of the experience of most people, those things were quite removed.
So by looking at the household as the fundamental space for religious experience and linking specific practices to the roles of women, women become as important actors in the religious lives of Israelites in terms of the household as priests are on the national or communal level.

The human face is an object that is easily located in complex scenes by infants and adults alike. Yet the development of an automated system to perform this task is extremely challenging. This paper is concerned with the development of a computational model for locating human faces in newspaper photographs based on cognitive research in human perceptual development. In the process of learning to recognize objects in the visual world, one could assume that natural growth favors the development of the abilities to detect the more essential features first. Hence, a study of the progress of an infant's visual abilities can be used to categorize the potential features in terms of their importance. The face locator developed by the authors takes a hypothesis gelaerate and test approach to the task of finding the locations of people's faces in digitized pictures. Information from the accompanying caption is used in the verification phase. The system successfully located all faces in 44 of the 60 (73%) test newspaper photographs.

New Molecule Binding Chloride Ions
Published on August 31, 2010 at 12:53 AM
Chemists at Indiana University Bloomington have designed a molecule that binds chloride ions -- but can be conveniently compelled to release the ions in the presence of ultraviolet light.
Reporting in the Journal of the American Chemical Society today (online), IU Bloomington chemist Amar Flood and Ph.D. student Yuran Hua explain how they designed the molecule, how it works and, just as importantly, how they know it works.
When azobenzene units (blue) at the ends of the receptor are struck with UV light, the receptor unfolds the helix and releases the chloride ion (green).
"One of the things we like most about this system is that the mechanism is predictable -- and it functions in the way we propose," said Flood, who led the project.
Chloride is a relatively common element on Earth, ubiquitous in seawater and in the bodies of living organisms.
"We have two main goals with this research," Flood said. "The first is to design an effective and flexible system for the removal of toxic, negatively charged ions from the environment or industrial waste. The second goal is to develop scientific and even medical applications. If a molecule similar to ours could be made water soluble and non-toxic, it could, say, benefit people with cystic fibrosis, who have a problem with chloride ions accumulating outside of certain cells."
Many organic molecules exist that can bind positively charged ions, or cations, and this has much to do with the fact that it is easy to synthesize organic molecules with negatively charged parts. Synthesizing organic molecules that bind negatively charged ions, or anions, like chloride, presents special challenges.
The binding molecule or "foldamer" Flood and Hua designed is both a folding molecule and a (small) polymer, meaning the foldamer's constituent parts can be synthesized with relative ease. Under visible light of 436 nanometers (nm), the foldamer prefers a tight spiral structure that allows specially configured residues to interact with each other, which improves stability, and creates an attractive pocket for chloride. In the presence of ultraviolet light (365 nm), the foldamer absorbs energy and the tight spiral is destabilized, weakening the chloride binding pocket and freeing chloride to re-enter the solution.
The "light switch" properties of the foldamer could make it an invaluable tool to biochemists and molecular biologists who seek to adjust the availability of chloride in their experiments by simply turning a UV light emitter on or off.
The foldamer is not quite ready for that, however. It can only be dissolved at present in organic (fatty) solutions, whereas living systems operate mostly in water-based solutions.
"That's the direction we're headed," Flood said. "It actually wouldn't be that difficult to modify the molecule so that it is water soluble. But first we need to make sure it does all the things we want it to do."
In their JACS paper, Flood said he and Hua wanted to bring sythentic chemistry together with modern diagnostic approaches to demonstrate the efficacy of their foldamer.
"A lot of the ideas in our paper have been floating around for some time," Flood said. "The idea of a foldamer that binds anions, the idea of a foldamer that you can isomerize with light, the idea of receptor that can bind anions... But none of the prior work uses conductivity to show that the chloride concentrations actually go up and down as intended. What's new is that we've put all these things together. We think we have something here that allows us to raise our heads to the great research that's preceded us."
Flood and Hua used an electrical conductivity test to show that when voltage is applied to the solution containing chloride ions and the binding molecule, electricity flows more freely in the presence of UV light, when the binder is relaxed and chloride is disassociated from it. That was proof, Flood said, that the foldamer was working as intended.
"My training is in building molecular machines," Flood said. "I create machines that do what we want them to do -- and to show what's possible in chemical and biological laboratory science."
The binding molecule Flood and Hua describe is an improvement on a previous binder developed by Flood and then-postdoctoral fellow Yongjun Li that was also an oligomer of sorts but did not fold. This previous iteration of the chloride binder was closed and donut-shaped, using space restrictions and strategically placed atoms to yield a binding pocket with a special affinity for chloride.

Deadly Sea Snakes: Alike But Not The Same
December 3, 2012
The lethal beaked sea snake is actually two species which separately evolved to give identical snakes.
AsianScientist (Dec. 3, 2012) – Researchers from Australia and Indonesia have discovered that the lethal beaked sea snake (Enhydrina schistosa) is actually two species with separate evolutions, which resulted in identical snakes.
Senior author Associate Professor Bryan Fry from The University of Queensland said the Australian and Asian beaked sea snakes were originally thought to be from the same species, however, in comparing their DNA, the research team had found these two snakes were unrelated.
Analyses of five independent mitochondrial and nuclear loci for populations spanning Australia, Indonesia, and Sri Lanka indicate that this 'species' actually consists of two distinct lineages in Asia and Australia that are not closest relatives.
The finding, published recently in the journal Molecular Phylogenetics & Evolution, is an example of a situation where two species evolved separately but ended up looking similar – a phenomenon known as convergent phenotypic evolution, says Fry.
Convergence in the characteristic 'beaked' morphology of these species is probably associated with the wide gape required to accommodate their spiny prey, he explained, as both species occupy the same specialized habitat of silt-filled shallows of tropical estuaries throughout the Asian and Australian regions.
The beaked sea snake is also responsible for the large majority of recorded deaths and injuries from sea snake bites.
Fortunately, the only available sea snake anti-venom available – raised against the Malaysian E. schistosa – is also effective against the new Australian species.
"This mixup could have been medically catastrophic, since the CSL sea snake antivenom is made using the venom from the Asian snake based on the assumption that it was the same species," said Fry. "Luckily, the antivenom is not only very effective against the Australian new species but actually against all sea snakes since they all share a very stream-lined fish-specific venom."
The Asian snake will retain the original name Enhydrina shistosa, while its Australian counterpart has been elevated to species status and is provisionally referred to as Enhydrina zweifeli, which identifies the region in New Guinea where it is found.
The new snake will be placed in a separate genus to the true Enhydrina genus in a follow-up publication that will resolve the complex higher order relationships of sea snakes.

Bigarray.Array0(3) OCaml library Bigarray.Array0(3)
Bigarray.Array0 - Zero-dimensional arrays.
Module Bigarray.Array0
Module Array0
: sig end
Zero-dimensional arrays. The Array0 structure provides operations similar to those of Bigarray.Genarray , but specialized to the case of zero-dimensional arrays that only contain a single scalar value. Statically knowing the number of dimensions of the array allows faster operations, and more precise static type-checking.
Since 4.05
type (!'a, !'b, !'c) t
The type of zero-dimensional Bigarrays whose elements have OCaml type 'a , representation kind 'b , and memory layout 'c .
val create : ('a, 'b) Bigarray.kind -> 'c Bigarray.layout -> ('a, 'b, 'c) t
Array0.create kind layout returns a new Bigarray of zero dimension. kind and layout determine the array element kind and the array layout as described for Bigarray.Genarray.create .
val init : ('a, 'b) Bigarray.kind -> 'c Bigarray.layout -> 'a -> ('a, 'b, 'c) t
Array0.init kind layout v behaves like Array0.create kind layout except that the element is additionally initialized to the value v .
Since 4.12
val kind : ('a, 'b, 'c) t -> ('a, 'b) Bigarray.kind
Return the kind of the given Bigarray.
val layout : ('a, 'b, 'c) t -> 'c Bigarray.layout
Return the layout of the given Bigarray.
val change_layout : ('a, 'b, 'c) t -> 'd Bigarray.layout -> ('a, 'b, 'd) t
Array0.change_layout a layout returns a Bigarray with the specified layout , sharing the data with a . No copying of elements is involved: the new array and the original array share the same storage space.
Since 4.06
val size_in_bytes : ('a, 'b, 'c) t -> int
size_in_bytes a is a 's Bigarray.kind_size_in_bytes .
val get : ('a, 'b, 'c) t -> 'a
Array0.get a returns the only element in a .
val set : ('a, 'b, 'c) t -> 'a -> unit
Array0.set a x v stores the value v in a .
val blit : ('a, 'b, 'c) t -> ('a, 'b, 'c) t -> unit
Copy the first Bigarray to the second Bigarray. See Bigarray.Genarray.blit for more details.
val fill : ('a, 'b, 'c) t -> 'a -> unit
Fill the given Bigarray with the given value. See Bigarray.Genarray.fill for more details.
val of_value : ('a, 'b) Bigarray.kind -> 'c Bigarray.layout -> 'a -> ('a, 'b, 'c) t
Build a zero-dimensional Bigarray initialized from the given value.

ReptiCare Ceramic Infrared Heat Emitter from Zoo Med
ReptiCare Ceramic Infrared Heat Emitter is the perfect heat source for your reptiles such as snakes, green iguana, and bearded dragons. Why we need to provide heat emitter to our pet reptiles? Well, reptiles are animals that live at high temperature areas such as desert. By providing the similar heat, it enables your pet reptiles to maintain their body temperatures. However, since each species has its own required body temperatures, therefore it's important to provide variation in temperature between one vivarium and the other. That's why Zoo Med offers several different units starting from 60w heat emitter, 100w heat emitter, and 150w heat emitter.

Rapid analysis of chloride content of contaminated concrete
MetadataShow full item record
To eliminate the problem of random manufacturer alternations, a generic method was developed for evaluating the chloride contents of concrete with the specification electrode. The method outlined the required equipment, the proportioning of the calibration solutions, the proportioning of the concrete digestion solution, and the measuring procedure. The developed method eliminated the problems of the digestion reaction temperature and the measurement inaccuracies of the higher chloride contents by diluting the measured concentrations.
The testing procedure was validated for field application by measuring the chloride contents of concrete samples from four state bridge structures. The analysis of operator variance proved the method was applicable to any operator capable of following the procedure.

Improving environmental outcomes for low income households in Marrickville
The concept of "green equity" - assisting low and modest income households in meeting the challenges of climate change - has only recently been introduced to Australia but is rapidly evolving.
Local councils have a key role to play, given that they are close to the communities they serve and are in a good position to target environmental initiatives to low income households that would normally have the least capacity to take advantage of such initiatives.
There are now opportunities for Marrickville Council to take a leading position on 'green equity' and to examine policy measures to assist low income households within the area to improve environmental outcomes and wellbeing.
For information on the strategies Council is implementing to improve environmental outcomes for low income households in the area, please download the following documents:
Anti Poverty Week presentation: Climate Change and its Social Impacts
During Anti Poverty Week 2007, Marrickville Council organised the Forum on Climate Change and its Social Impacts at the Petersham Town Hall to identify and discuss the equity issues associated with climate change.

An edit control that is not read-only or disabled sends the WM_CTLCOLOREDIT message to its parent window when the control is about to be drawn. By responding to this message, the parent window can use the specified device context handle to set the text and background colors of the edit control.
WM_CTLCOLOREDIT WPARAM wParam; LPARAM lParam;
A handle to the device context for the edit control window.
A handle to the edit control.
If an application processes this message, it must return the handle of a brush. The system uses the brush to paint the background of the edit control.
If the application returns a brush that it created (for example, by using the CreateSolidBrush or CreateBrushIndirect function), the application must free the brush. If the application returns a system brush (for example, one that was retrieved by the GetStockObject or GetSysColorBrush function), the application does not need to free the brush.
By default, the DefWindowProc function selects the default system colors for the edit control.
Read-only or disabled edit controls do not send the WM_CTLCOLOREDIT message; instead, they send the WM_CTLCOLORSTATIC message.
The WM_CTLCOLOREDIT message is never sent between threads, it is only sent within the same thread.
If a dialog box procedure handles this message, it should cast the desired return value to a INT_PTR and return the value directly. If the dialog box procedure returns FALSE, then default message handling is performed. The DWL_MSGRESULT value set by the SetWindowLong function is ignored.
Rich Edit: This message is not supported. To set the background color for a rich edit control, use the EM_SETBKGNDCOLOR message.

Optimising capercaillie (Tetrao urogallus) habitat suitability through alternative management regimes in Scottish plantation forests
Capercaillie numbers in Scotland are declining rapidly and it is accepted that improved habitat management would make a key contribution to any future recovery. In order to do this, managers of commercial forests need to consider the trade-offs between timber production and improved habitat for capercaillie. This research involves the development of a decision tool that uses optimisation methods to systematically investigate this issue. A model that links forest sub-compartment (management unit) characteristics to capercaillie habitat suitability was constructed. Eleven experts evaluated 32 images representing pre-defined forest habitat types. These habitat types were derived using only data available from Forest Enterprise forest inventories and yield models, therefore, they may be predicted directly for any similarly inventoried forest. The Delphi process allowed the experts to reach a consensus regarding the area dependent habitat suitability functions for each habitat type. Following a field validation of the model, the functions were incorporated in a GIS based forest inventory. This allows capercaillie habitat suitability to be calculated for each sub-compartment in a forest. A spreadsheet model was then developed to calculate the timber volume per hectare for possible alternative silvicultural regimes for each sub-compartment. A linear programme then selects the harvesting options for each sub-compartment that return the highest possible score for the forest, five years post management, whilst still meeting specified timer output requirements for the current five year planning period. Two forests representing a conservation forest (Glenmore) and a commercial forest (Inshriach) were selected for case studies. When applied to a range of management scenarios, the model dramatically enhanced habitat suitability whilst allowing timber output targets to be achieved. Various output data, including names of practical use to forest managers are presented.

| Product Description :
||Abrasive discs consist of abrasive grains applied to a backing made of cloth, fiber, film, paper, non-woven, or other material. The abrasive grains remove surface materials such as metal, ceramics, glass, plastics, and paint. Consequently, abrasive discs are used in wet and dry grinding, sanding, cleaning, polishing, and surface preparation in a variety of industries, including metalworking, woodworking, ceramics, and semiconductors. A disc's backing, abrasive grain, grit size, and mounting help determine its applications.

Event Archive - Galiano Ensemble Performs "Hungarian Inspiration": The Galiano Ensemble of Victoria
Wed. January 25th 2017 Phillip T. Young Recital Hall (Uvic) (All Ages)
8:00 pm doors at 7:30 pm
$33 ($30 seniors)
Tickets at: Ivy's Books, Munro's Books
You are warmly invited to join the Galiano Ensemble of Victoria for its first concert of 2017. The Ensemble will perform an assortment of enchanting pieces from several Hungarian composers and one Canadian composer.
Franz (Ferenc) Liszt was born in 1811 and was recognized as a virtuoso pianist from a young age. He was a conductor and prolific composer whose works are considered to have been very influential on 19th and 20th century composers. His Angélus! Prière aux anges gardiens (Prayer to the Guardian Angels) was dedicated to his granddaughter. This string orchestra arrangement was originally written for a melodeon (pump organ) or piano.
Bela Bartok was a composer, pianist and music teacher born in 1881. Bartok and Liszt are considered the two greatest Hungarian composers and Bartok is thought to have been one of the most important composers of the 20th century. Hungarian folks songs were a significant influence on his works. Bartok's Divertimento for String Orchestra was his last work, composed just before he reluctantly fled Hungary and emigrated to the United States in 1940 because of concerns about the war and his disdain for the Nazi regime.
Leó Weiner, a contemporary of Bartok, was a composer born in 1885. Weiner was also recognized as a leading Hungarian music educator during the first half of the 20th century. His interest in folk music is evident in many of his compositions including Hungarian Folk Tunes.
Srul Irving Glick, born in Toronto in 1934, was one of Canada's most prolific composers as well as a conductor, teacher and radio producer. He composed Suite Hébraïque No. 1 in 1961 while living in Paris and feeling nostalgic for his home and family. His father was a cantor and his affinity for Jewish music inspired many of his works.
Conductor Yariv Aloni and the orchestra are sure to provide an entertaining evening of chamber music so be certain to put this in your calendar and tell your friends!

Lab #10: String Validation
Email your instructor showing what you have completed. You can get partial credit even if not fully completed with the lab.|
The goal of this assignment is to allow you to become familiar with string validation. Review the previous lab introducing strings.
Validating input is essential to administrating an account system for a website. If your account system requires a valid email address and sufficiently complex password (for security purposes), it is better to check the input first to see if it meets expectations than wait for an error to occur.
Hint: One way to check if a type of character exists in a string is to have a string containing all characters of that type, then using indexOf to search for that letter.
Part 1: Email
An email typically looks like _EMAIL_, but the extension could also be.gov,.org,.edu as well as extensions indicating other countries such as.uk or.ca. For our purposes, we will only check if there are
Notify the user (with alert or document.write) if the email is invalid.
- 2 or 3 characters after the last period in the string.
- A single @ in the string.
Part 2: Password
Password complexity is essential to security as more permitted characters and increasing the length of passwords make them harder to guess. We will only check if there are
Note: toUpperCase() and toLowerCase() will transform numbers and special characters.
- At least one lowercase character
- At least one uppercase character
- At least one number
- At least one special character (!,@,#,$,%,^,&,*,~)

This can be used to demod FM, FSK, GMSK, etc. The input is complex baseband, output is the signal frequency in relation to the sample rate, multiplied with the gain.
Mathematically, this block calculates the product of the one-sample delayed input and the conjugate undelayed signal, and then calculates the argument of the resulting complex number:
Let x be a complex sinusoid with amplitude A>0, (absolute) frequency f\in\mathbb R and phase sampled at f_s>0 so, without loss of generality,
is real, so is and hence only scales, therefore is invariant: = arg
Gain setting to adjust the output amplitude. Set based on converting the phase difference between samples to a nominal output value.
