The Weil Pairing
Consider the group of $m$-torsion points $E[m]$ for some $m$ coprime to $q = \mathrm{char} K$.
For a point $T \in E[m]$, find a $T_0$ such that $m T_0 = T$ (i.e. $T_0 \in [m]^{-1}(T)$). Let $g_T$ be a rational function with divisor
\[ \langle g_T \rangle = \sum_{R\in E[m]} \langle T_0 + R \rangle - \langle R \rangle \]
Let $\tau_S$ be the translation-by-$S$ map for some $m$-torsion point $S$. Then define the Weil pairing to be
\[ e(S,T) = \frac{g_T \cdot \tau_s }{ g_T } \]
Since $R, S$ are both elements of the group $E[m]$:
\[ \langle g_T \cdot \tau_S (P) \rangle = \sum_{R\in E[m]} \langle T_0 + R - S \rangle - \langle R - S \rangle = \langle g_T \rangle \]
So $g_T$ and $g_T \cdot \tau_S$ have the same divisor which implies $e(S, T) = g_T \cdot \tau_S / g_T = \mu$ for some constant $\mu$ (recall that $g_T$ is unique up to a constant).
Repeating this argument gives $g_T \cdot \tau_S^i = \mu^i g_T$. Since $m$ translations by $S$ is the identity (since $S \in E[m]$) we find $\mu^m = 1$, when $i = m$. In other words $e(S,T) = \mu$ is an $m$th root of unity.
So we may view the Weil pairing as a map
\[ e : E[m] \times E[m] \rightarrow \mu_m \]
where $\mu_m$ is the group of the $m$th roots of unity.
Note this definition of the Weil pairing is not suitable for practical computations as the representations of the functions $g_T(P), g_T(P+S)$ grow quickly with $m$. (There are $2m^2$ poles and zeroes for each function, which means each function is a product of $2m^2$ line equations.) Fortunately an alternative definition of the Weil pairing lends itself well to explicit computation.
Pullback of Divisors
This is another way to view this definition of the Weil pairing.
Suppose $\alpha$ is an endomorphism, and $g$ is a rational function. Then a natural construct is to compose $g$ and $\alpha$, i.e. $g \cdot \alpha$.
For example, if $\alpha$ is translation by a point $T$, then $g \cdot \alpha (P)= g(P+T)$.
The map $\alpha$ also induces a map on the divisors $\alpha^* : Div(E) \rightarrow Div(E)$ that takes the divisor of $g$ to the divisor of $g \cdot \alpha$.
For example, if $\alpha$ is translation by $T$, then $\alpha^*$ takes a divisor $\sum m_P \langle P \rangle$ to $\sum m_P \langle P - T \rangle$.
Then the function $g_T$ in the Weil pairing may be defined as a function such that
\[ \langle g_T \rangle = [m]^*(\langle T \rangle - \langle O \rangle) \]
Properties of The Weil Pairing
The Weil pairing is nondegenerate, alternating and bilinear.
 - $e(S_1 + S_2, T) = e(S_1, T) e(S_2, T)$
 - $e(S, T_1 + T_2) = e(S, T_1) e(S, T_2)$
 - $e(S, S) = 1$
 - $e(S, T) = e(T, S)^{-1}$
 - $e(S, T) = 1$ for all $T$ if and only if $S = O$
 - $e(S, T) = 1$ for all $S$ if and only if $T = O$
 - For any nonzero endomorphism $\alpha$, $e(\alpha(S), \alpha(T)) = e(S,T)^{\deg \alpha}$

Homemade Dog Toys: A Cost Free And Eco-Friendly Solution for Your Friend
how to make dog toys
Anna Smith
Written by Anna Smith
Toys are an indispensable item in any dog's life especially if he or she is expected to lead a healthy and productive life. By being able to facilitate mental stimulation, toys play a key role in alleviating separation anxiety, discouraging destructive behaviors, boosting social behaviors and encouraging the dog to live a happy and productive life. But when it comes to toy selection, most dog owners usually feel obliged to purchase costly ones instead of looking for other affordable or non-costly alternatives.
Also, due to the hefty price tags on most play items, most owners can only make one or two purchases at a go. But not known by too many people, there is an inexpensive alternative that can assist pet owners in saving tons of cash while achieving the same result as they would have with a new play item.
Apart from being very easy to design, homemade toys are also very cheap to make and at times no costs are incurred as long as the pet owner has all the necessary assemblage parts at his disposal. Furthermore, homemade play items are ideal because they tend to increase the life cycle of various disposables. Hence, they are eco-friendly and a green solution to items that would have normally been discarded as waste. See more homemade goodies in our easy to make DIY dog toys that are inexpensive, as well.
Make a toy for your dog out of socks
Needless to say, the home designed play items are just as effective as purchased play items because they all achieve similar results. But, like shop toys, there are several issues that every dog owner must put into consideration before selecting a suitable play item designs. Without addressing these issues of concern at the initial stages, the results may be dire on your dog with some instances necessitating the need for emergency medical attention. Hence, here are some of the things that every dog owner must consider before selecting an ideal homemade toy design.
Things to consider before selecting the ideal homemade dog toy
Establishing where your dog lies on the chew meter is essential especially when it comes to the selection of an ideal toy. Various toys such as the recycled plastic bottle toys are not suitable for very strong chewers because they can be punctured or torn easily. Hence, dogs that are on the upper scale of the chew meter it is indispensable to provide them with homemade playtime items.
The play items should be designed from materials that are not only durable but also strong enough to tolerate aggressive chewing. Also, the material should not only withstand the belligerent chewing but it must also not wither, shred, crack, rip or puncture in the process. This aspect is very important because once ingested, the small particles from the toy may induce choking, vomiting and many other gastrointestinal complications. All in all, if your pet is an aggressive chewer, you should consider toys that have been constructed from ultra-durable constituents such as rubber.
Dog sock toy
Apart from the chew meter, another thing that you should always put into contemplation when planning to either build or purchase a play item for your pet is the ratio between the toy and the dog. It is essential for the size of the toy to be directly proportional to the size of the dog. If the size of the play item is smaller when compared to your dog's size, they can be easily swallowed which will eventually lead to unwarranted medical expenses.
Furthermore, before handing a toy to your dog, always ensure that small sized items that may be attached to the item or could be swallowed easily are eliminated before handing the toy to the pet. See our guidelines on the top dog-friendly chew toys that are suitable for your pooch.
Your pet's age also plays a key role when it comes to the selection of an ideal play item. Despite the fact that the desire to chew is usually a natural instinct in all canines, it is usually at its highest point during the developmental stages that are usually between eight weeks and six months. Hence, so as to release the discomfort present in his or her gums, your puppy is going clump onto anything that is chewable.
When searching for an ideal play item for your puppy, you should always ensure that the item of your choice will not be injurious in anyway. Also, toys that have been designed from materials such as plastics must be avoided at all costs. Alternatively, the owner should opt for materials that are going to have a soothing effect on the puppy such as splash balls. Why not see our list of topnotch and cool dog toys that your furry companion might like?
Puppy and homemade dog toy
Homemade edible toys are also another option that homeowners can make for their puppies. Needless to say, edible play items are a good occasional treat for puppies because they play a key role in keeping the pearly white teeth clean. Also, edibles can be used to freshen the puppy's breath and keep him or her interested for a very long time.
While putting all aspects into consideration, there are a wide range of options available for dogs of all ages and all of this preferences can be produced locally without the need for extra costs. Hence, before selecting an ideal toy design for dogs, factors such as the age and the chew meter must also be kept under consideration.
Benefits of homemade toys
Unlike manufactured toys, homemade dog toys are very cheap to make and at times there are no costs involved as long as the dog owner has all the necessary parts required for the assembly process. Most of the necessary materials and toy parts may be obtained easily from various recyclables such as old clothes, plastic bottles, tennis balls and many others. Another benefit of homemade toys is that they are usually easy to make. Hence, you can have as many play items for your pet as you want with very little skills and without any financial restrictions whatsoever.
Needless to say, play items whether purchased or homemade are important because they provide mental stimulation and alleviate separation anxiety. All dog breeds will require some form of mental stimulation if they are to lead a healthy and productive life. Homemade toys can be a great tool for instigating mental stimulation in dogs. Besides, play items can be used to alleviate separation anxiety that is usually common in dogs that may need attention from time to time. Our piece on how to choose the right dog toys to keep Buster preoccupied is a worthwhile read.
Another benefit of homemade toys is that they can be employed as an effective tool when it comes to combating destructive behaviors in dogs. By providing your dog with a play item, he or she is going to use the item as a positive outlet for the unnecessary physical energy. The play items can be used to strengthen the bond between you and the dog because you will be going to spend more time with him or her while having fun. Furthermore, toys are essential in promoting dental health because they can be used as a form of exercise for the jaw muscles.
Finally, homemade toys can be used as a clean-up process because most of the materials used in the assemblage process are mainly recyclables. Because most recyclables often reach a point where they can no longer be useful; assembling a play item for your pet from these materials is indeed a great way of improving the material's life cycle. Also, items such as clothing, once they have been used as a play item they tend to become easily decompose due to the wear and tear effect inflicted on them.
Five homemade toy designs that every dog owner must try out
The whipwhir
The Whipwhir also commonly referred to as the stick and rope toy is undeniably one of the best toy ideas, especially for dogs with high energy levels. Apart from being exceedingly unique the Whipwhir is also very easy to make and will at times require zero budget as long as you have all the necessary materials. Unlike most toys that may be used explicitly either on the inside or the outside, the Whipwir is among the few toys that can be used on both platforms.
But for individuals who will use this toy inside the house it is very indispensable that they should ensure they have more than enough space for the dog to move freely.
For the assembly of this toy, you will be required to have an old broomstick that has a hole drilled on one end. Also, you will also need a six-foot rope or cord and a toy preferably a tennis ball or an old sock. After finding the all the necessary items, you are to begin the assembly process by fastening the rope on one end of the old broomstick preferably the end with a hole. The final huddle of this design, mainly entails tying the toy i.e. sock, braided rugs, and tennis ball on the end of the cord or rope and your toy is good to go.
Like any other toy, the Whipwhir unquestionably has some safety guidelines especially because it is an ideal toy for high energy dogs. While using this toy, there is a possibility of the dog getting injured when it becomes over exuberant. Hence, you are required to ensure that the dog is properly warmed up before you begin any playing session. Also, it is highly prudent that the distance between the ground and the toy should be reasonable. Most sporting dog breeds can benefit from this kind of toy and high-energy activities, so read all about it in our previous article.
Recycled drinking bottle
The recycled drinking bottle toy is one of the easiest toys to make because all it requires is an old drinking bottle and a little bit of effort. This type of toy is a favorite among all dog species because of the cracking and crinkly sound that it produced when chewed on by a dog. Before handing the recycled drinking bottle to the pet, always ensure that the lid, and the ring, which is usually attached to the lid have all been carefully removed.
Furthermore, if your dog


Simple introduction to Fork-Join Framework in Java 7
Fork-Join Framework was added as part of Java 7 which makes use of the ExecutorService interface to distribute tasks to the worker threads in the thread pool. The difference in Fork-Join is that the ideal worker threads can steal queued subtasks from the other tasks and execute them.
also read:
There are a few important classes you should be aware of:
 - ForkJoinPool
 - RecursiveTask
 - ForkJoinTask
 - RecursiveAction
ForkJoinTask:
This represents the abstract task which runs within the ForkJoinPool. They are lightweight threads in the sense quite a lot of tasks can run withing few threads with some restrictions. There are two methods: fork() and join(). fork() is used to spawn new tasks, where as join() waits for the completion of the task. There are two extensions of ForkJoinTask- RecursiveTask and RecursiveAction. RecursiveTask is used when the task is expected to return some value, while RecursiveAction is used when the task preforms some action but doesn't return any value. It is recommended to extend either RecursiveAction or RecursiveTask and not directly extend ForkJoinTask.
RecursiveTask:
This is a subclass of ForkJoinTask whose compute method returns some value.
RecursiveAction:
This is a subclass of ForkJoinTask whose compute method doesn't return any value.
ForkJoinPool:
It is an ExecutorService for running ForkJoinTasks and also managing and monitoring the tasks. It employs worker-stealing algorithm where in idle threads can pick subtasks created by other active tasks and execute them. In this way there is efficient execution of tasks spawned by other tasks.
Lets see how we can find sum of some 1000 integers using ForkJoin framework. This is quite a trivial example and not worthy of being implemented as ForkJoin. The main motive behind this is to throw some light of the implementation aspects of ForkJoin.
In this example we will divide the array of integers into half and assign each half to a RecursiveTask. If the array size is less than 20 elements then we assign it to another RecursiveTask which would return the computed sum of those array elements.
RecursiveTask for computing the sum
//Task for computing the sum of array elements.
class SumCalculatorTask extends RecursiveTask<Integer>{
 int [] numbers;
 SumCalculatorTask(int[] numbers){
 this.numbers = numbers;
 }

 @Override
 protected Integer compute() {
 int sum = 0;
 for (int i : numbers){
 sum += i;
 }
 return sum;
 }
}
The compute method has to be overridden with the actual task to be performed. In the above case its iterate through the elements of the array and return the computed sum.
RecursiveTask for dividing the array
We create a RecursiveTask for dividing the array into two parts and assign each part to another RecursiveTask for further dividing. We continue dividing the array and stop dividing when the array has less than 20 elements.
class NumberDividerTask extends RecursiveTask<Integer>{
 int [] numbers;
 NumberDividerTask(int [] numbers){
 this.numbers = numbers;
 }
 /*
 * If the array has less than 20 elements, then
 * just compute the sum, else split the array further.
 */
 @Override
 protected Integer compute() {
 int sum = 0;
 List<RecursiveTask<Integer>> forks = new ArrayList<>();
 if ( numbers.length > 20){
 NumberDividerTask numberDividerTaskFirst =
 new NumberDividerTask(Arrays
 .copyOfRange(numbers, 0, _URL_
 NumberDividerTask numberDividerTaskSecond =
 new NumberDividerTask(Arrays
 .copyOfRange(numbers, numbers.length/2, numbers.length));
 forks.add(numberDividerTaskFirst);
 forks.add(numberDividerTaskSecond);
 numberDividerTaskFirst.fork();
 numberDividerTaskSecond.fork();
 }
 else{
 SumCalculatorTask sumCalculatorTask = new SumCalculatorTask(numbers);
 forks.add(sumCalculatorTask);
 sumCalculatorTask.fork();
 }

 //Combine the result from all the tasks
 for ( RecursiveTask<Integer> task : forks){
 sum += task.join();
 }
 return sum;

 }
}
Each of the above task spawns either 2 other NumberDividerTask or a SumCalculatorTask. Each task keeps a track of the sub tasks it has spawned in the forks. At the end of the task we wait for all the tasks in the forks list to finish by invoking join() method and add the return values from each of the subtasks.
To invoke the above defined tasks we make use of ForkJoinPool and create a NumberDividerTask task by giving it the array whose sum we wish to compute.
public class ForkJoinTest {
 static ForkJoinPool forkJoinPool = new ForkJoinPool();
 public static final int LENGTH = 1000;
 public static void main(String[] args) {
 int [] numbers = new int[LENGTH];
 //Create an array with some values.
 for(int i=0; i<LENGTH; i++){
 numbers[i] = i * 2;
 }
 /*
 * Invoke the NumberDividerTask with the array
 * which in turn creates multiple sub tasks.
 */
 int sum = forkJoinPool.invoke(new NumberDividerTask(numbers));

 System.out.println("Sum: "+sum);
 }
}
The output: Sum: 999000.
This is just a basic, trivial example of using ForkJoin framework. I know this sum computation could have been implemented sequentially, but the idea here is to understand the working of the ForkJoin. In future I would try and post a ForkJoin version of some Divide and Conquer algorithm.

text: Perhaps the most obvious feature of the temple is its relative size and emptiness. Most citizens of Seacourt worship at private shrines or pray to foreign gods. The gods and goddesses of the ocean are much more important to the citizens of Seacourt than the Twelve Lords who, according to local legend, hold most of their power on land. Furthermore, the hill upon which the Abbarathian sits is surrounded by the wealthy elite and the offices of municipal power. It isn't particularly inviting to the commoners, sailors, or foreigners who make up the majority of Seacourt's population from day-to-day.

A kymograph (which means 'wave writer') is a device that gives a graphical representation of spatial position over time in which a spatial axis represents time. It basically consists of a revolving drum wrapped with a sheet of paper on which a stylus moves back and forth recording perceived changes of phenomena such as motion or pressure.
It was invented by German physiologist Carl Ludwig in the 1840s and found its first use as a means to intrusively monitor blood pressure, and has found several applications in the field of medicine. Its primary use was to measure phenomena such as changes in muscular contractions or other physiological processes, including speech sounds and electrophysiological recordings.

Angular 2 – How to get template reference variable or directive instance inside component
In this post let us see how to get Angular 2 directive/child component instance inside the parent component class.
ViewChild in action
The ViewChild decorator can be used to achieve this requirement.
The ViewChild accepts either the directive type or the template reference variable as argument and set the directive instance to the target property after the view get initiated.
@Component({
 selector: 'child-cmp',
 template: '
child
'
})
class ChildCmp {
 doSomething() {}
}
@Component({
 selector: 'some-cmp',
 template: '<child-cmp></child-cmp>',
 directives: [ChildCmp]
})
class SomeCmp {
 @ViewChild(ChildCmp) child:ChildCmp;
 ngAfterViewInit() {
 // child is set
 this.child.doSomething();
 }
}
The ViewChild will set the target property once the component view get rendered hence accessing the property before the view get initiated will return inappropriate result.
You can use the ngViewAfterInit lifecycle hook to identify the view initialization.
Argument as Directive type vs template variable
Using argument as template variable ViewChild is best from my point of view as it will provide access to specific directive instance when having more than one directive in the template.
@Component({
 selector: 'some-cmp',
 template: '<child-cmp #child></child-cmp>',
 directives: [ChildCmp]
})
class SomeCmp {
 @ViewChild('child') child:ChildCmp;
 ngAfterViewInit() {
 // child is set
 this.child.doSomething();
 }
}
Happy Scripting.. 🙂

This is an already known technique. Using document fragment allow the separation of DOM creation from live document so that it will avoid unnecessary browser reflow and repaint.
var fragment= document.createDocumentFragment();
fragment.appendChild(document.createElement("div"));
Clone nodes
Cloning already created element using cloneNode. This will be helpful when creating large number of same element. Mostly likely it can be used while creating table tr elements from JSON.
var fragment= document.createDocumentFragment();
var div = document.createElement("div");
fragment.appendChild(div.cloneNode(false));
Batch DOM update
Always batch the DOM update. Batch the DOM changes will reduce browser reflow and repaint.
Using requestAnimationFrame for DOM changes
This technique will provide a considerable performance when changing the live document. requestAnimationFrame will be used to update the DOM changes when the next reflow/repaint happens.
Normally it is introduced to do smooth animation experience in browser but here we can use this to do a single DOM update.
requestAnimationFrame(function(){
 document.body.appendChild( document.createElement("div") );
});
Use insertAdjacentHTML instead of innerHTML
This will be used when we need to append dynamic content to the same element.
We can use the innerHTML as follows.
var div = document.createElement("div");
div.innerHTML ="Hi" //
Hi

div.innerHTML += " Dude"; //
Hi Dude

But the above one have significant performance impact as it needs to re-parse all the child element already present.
To overcome this we can use insertAdjacentHTML which will append the inner HTML without touching the other elements. It only parses the new HTML need to be appended.
var div = document.createElement("div");
div.innerHTML = "Hi"; //
Hi

div.insertAdjacentHTML("afterend", " Dude"); //
Hi Dude

Following the above methods will provide a better performance in most of the modern browsers.
Happy scripting….
Replace () as call back function
We know that the replace() method will return a new string based on the pattern and its corresponding replacement argument.
Here the pattern can be either general string or regular expression that we normally use. And for replacement argument in most cases we use string as replacement. But there is an extensible facility to use this replacement as call back function.
Here we go with a small example code snippets.
Code Snippets:
var numbers = '34 55 27 45 72',
type1 = numbers.replace(/\d+/g, '*'),
type2 = numbers.replace(/\d+/g, function (item) {
return +item < 50 ? '*' : item;
});
console.log("simple replace() : ", type1);
console.log("replace() with call back function : ", type2);
Fiddle Demo
Note:
The call back function will be invoked for the each matched set of an item, when the first parameter regular expression is declared as global.
Deleter – Node based directory removing tool
My first node package deleter, has been released. Its a CLI, which is used to remove directories. I come up with idea to create this when i faced difficulties in deleting node_modules from my node based applications.
Installation
npm install deleter -g
Since it is a CLI, global installation is preferred.
Usage
deleter <directory-name>
Example
deleter node_modules
Limitations
For now, its target for windows operating system and other OS will be considered in upcoming updates.

Why new keyword should be used while instantiating JavaScript class
The new keyword is used to instantiate prototypical class or other objects. But why we need new keyword to initialize it, when you to try to initialize it without new will not throw any error at all then why should I use new before my class to instantiate it.
The answer is simple new keyword will set the 'this' to the new object created using function instead of global scope".
If you didn't provided new keyword then the context will be set to window(global scope).
You can see the difference in the below code example.
var fn = function (){
 this.a = 2;
 return this;
}
Instantiating fn without new keyword.
 var f = fn(); //'this' refers window here.
Instantiating fn with new keyword.
 var f = new fn(); //'this' refer object created by 'fn' here.
Even though using new keyword is the best practice to instantiate class, most of the time, the users will skip them as it doesn't provide any error at all.
We can use the below simple workaround to enforce the instantiating process using new keyword. Then the above fn will become as below.
 var fn = function (){
 if(!(this instanceof fn)) //workaround to resolve this problem.
 return new fn();
 this.a = 2;
 return this;
}
Now instantiating without new will also set this to the current object.
 var f = fn(); //this refer to fn here.
Instantiating class/function without new keyword in ES6 will throw TypeError.
Happy Scripting… 🙂
Some alternative use of bit wise operators
In this blog, I am just going to share some of the alternative use of the bitwise operators.
1. Replace Math.floor with double ~~.
Even though JavaScript Math library is well optimized, we can use the bitwise operators to reduce some keystrokes.
~~3.4 //result : 3
2. Convert to Boolean using !!
Double NOT operator is used to convert any type into Boolean.
var d = &quot;Hi&quot;;
!!d //result : true
var f = null;
!!f //result : false
3. Swap values without temp variable using XOR.
It is the one of the common method used to swap two variables without using temp variable.
var a = 5, b= 6;
a ^= b; b ^= a; a ^= b; //result a = 6, b = 5;
4. Using left and right shift with 1 bit to perform multiply and division.
Left shifting a number 1 bit is equivalent to the result obtained by multiplying it by 2 and right shifting 1 bit is equivalent to dividing it by 2.
var d = 4, f = 6;
d >> 1 //result : 4 * 2 = 8
f << 1 //result : 6 / 2 = 3
5. Checking odd/even

Not all volcaanicn soils are more fertile because the ash that comes from volcanoes differs in its mineral content and in its physical properties. However volcaninc soils are often more fertile because they are relatively unweatherd. They have not undergone extensive leaching and they tend to contain more of the basic cations that plants require. These include Mg Ca K Older soils have less of these because they are leached out by water percolation As this leaching ocurs, soils often get more acidic. An increase in acidity often results in a decrease of availability for many essential nutrients and a corresponding increase in the concentration of nutrients that may be dangerous or toxic to plant, such as alumunium. So the answer to your question is that many volcanic soils are relatively younger thatn other soils and have greater amounts of essential nutrients that make them fertile.

Stall Catchers is a citizen science game, developed by the Human Computation Institute as part of the EyesOnALZ project in 2016.
Funded by a grant from the BrightFocus Foundation, HCI has been collaborating with Cornell, Berkeley, Princeton, WiredDifferently, and SciStarter to develop a platform for crowdsourcing the AD research being done at Cornell University.
"Stall Catchers" will allows participants to look at movies of real blood vessels in mouse brains, and search for "stalls" – clogged capillaries where blood is no longer flowing. By "catching stalls" participants can build up their score, level up and compete in the game leaderboard, as well as receive digital badges for their various achievements in the game.
Most importantly, the game will enable the crowdsourcing of promising Alzheimer's research at the Schaffer-Nishimura Laboratory (Cornell Dept. of Biomedical Engineering). There, recent breakthroughs have been made in understanding the role of reduced brain blood flow in AD, and reversing some of the Alzheimer's symptoms, such as memory loss and mood changes, by targeting blood vessel stalls.
Stall Catchers has been built on the existing platform of stardust@home – one of the first volunteer thinking projects. Just as aerogel images were being studied in stardust@home to look for interstellar dust particles, in Stall Catchers a "Virtual Microscope" plays back vessel movies – images of consecutive layers of a live mouse brain. Participants analyze one microscopic vessel at the time, looking for signs of stalls.
The game, launched Oct. 1, 2016, is expected to remove the current analytic bottleneck of blood flow analysis in AD, and accelerate the research towards promising AD treatment candidates.
Crowd2Map Tanzania is a crowdsourced initiative aimed at creating a comprehensive map of rural Tanzania, including detailed depictions of all of its villages, roads and public resources (such as schools, shops, offices etc.) in OpenStreetMap for everyone to use.
By turning complex laboratory analysis into a game (Stall Catchers) that anyone can play, EyesOnALZ has made it possible to accelerate Cornell's promising Alzheimer's disease research to compress decades of inquiry into just a few years.
Human Computation Institute is leading an initiative to develop an online Citizen Science platform that will enable the general public to contribute directly to Alzheimer's Disease research and possibly lead to a new treatment target in just a few years.
It has long been known that reduced blood flow in the brain is associated with Alzheimer's Disease and other forms of dementia. However, new imaging techniques have enabled our Cornell-based collaborators to make important discoveries about the mechanisms that underlie this reduced blood flow.
These findings are suggestive of a new treatment approach that could reduce cognitive symptoms and halt disease progression. However, arriving at a specific treatment target based on these findings requires additional research. Unfortunately, the data curation required to advance these studies is very labor-intensive, such that one hour's worth of collected data requires a weeks worth of annotation by laboratory personnel. Indeed, the curation aspect of the analysis is so time consuming that to complete the studies necessary for identifying a drug target could take decades.
Fortunately, accurate curation of the data, though still impossible for machines, involves perceptual tasks that are very easy for humans. We aim to address the analytic bottleneck via crowdsourcing using a divide-and-conquer strategy. The curation tasks in this research map closely to the tasks used in two existing citizen science platforms: stardust@home and EyeWire, both of which have enabled discoveries reported in the journal Science. In direct collaboration with the creators of these highly successful citizen science platforms, we are developing a new platform for public participation that we expect will reduce the time to a treatment from decades to only a few years.
If you are interested in participating in an online activity that will directly contribute to Alzheimer's research, please pre-register here. By participating, you will not only help speed up a treatment, but also understand more about the disease and exactly how your efforts make a difference.
Abstract (the full paper is available here as a PDF)
Humans are the most effective integrators and producers of information, directly and through the use of information-processing inventions. As these inventions become increasingly sophisticated, the substantive role of humans in processing information will tend toward capabilities that derive from our most complex cognitive processes, e.g., abstraction, creativity, and applied world knowledge. Through the advancement of human computation – methods that leverage the respective strengths of humans and machines in distributed information-processing systems – formerly discrete processes will combine synergistically into increasingly integrated and complex information processing systems. These new, collective systems will exhibit an unprecedented degree of predictive accuracy in modeling physical and techno-social processes, and may ultimately coalesce into a single unified predictive organism, with the capacity to address society's most wicked problems and achieve planetary homeostasis.
HC Institute director, Pietro Michelucci, led a multidisciplinary group of world experts in the emerging field of "human computation" in Washington, DC last week to consider the unprecedented capabilities that might arise from crowd-powered systems and to map out the research needed to get there.
The workshop itself employed human computation techniques in service of its own goals, such as participatory gaming, workflow execution, group composition, and interaction mechanics. Through these methods, workshop participants explored human motivation in participatory systems, worst-case scenarios, mapped out high impact success cases, and iteratively developed new human computation solutions to societal problems to help identify research gaps and inform related national policies.
The three-day workshop, held at the Woodrow Wilson International Center for Scholars, was proposed and co-organized by the Human Computation Institute, Cornell University, and the Wilson Center, and funded by the Computing Community Consortium (CCC). A workshop report, under development by the co-organizers and community of participants, is expected to be published by the CCC in early 2015.
*** UPDATE: workshop report now available here ***
Event coverage links:
HC Institute director, Pietro Michelucci, participated in a White House meeting this afternoon to discuss crowd engagement methods that involve game-like elements. This was the first in a series of Washington, DC-based events titled "Games & Crowds: Using Computer Games to Maximize Crowdsourcing Outcomes", to explore the societal value of such methods and prospective related initiatives. In a follow-on event, Dr. Michelucci will be presenting tomorrow at George Mason University on the topic of "Building Contentment" and the prospective role of gamification in the future of human labor.

We have a 16.8% interest in the offshore Kashagan field, where the North Caspian Operating Company is the operator. This shallow-water field covers an area of approximately 3,400 square kilometres. Phase 1 development of the field is expected to lead to plateau production of approximately 300 thousand boe/d, increasing further with additional phases of development. After the start of production from the Kashagan field in September 2013, operations had to be stopped in October due to gas leaks from the sour gas pipeline. Investigations and repair activities are ongoing.

The Albuquerque-Bernalillo County Air Quality Control Board (Air Board) authority was established by the New Mexico State Legislature in 1967 when the Legislature adopted the Air Quality Control Act (State Air Act) authorizing the City of Albuquerque and Bernalillo County to adopt ordinances providing for the creation of the Air Board.
The City and the County adopted parallel ordinances, creating the Air Board shortly after the Air Act was adopted. The primary function of the Air Board is to ensure that provisions of the United States Clean Air Act are implemented. According to the State Air Act, the Board shall "adopt, promulgate, publish, amend and repeal regulations consistent with the [State Air Act] to attain and maintain national ambient air quality standards and prevent or abate air pollution, including regulations prescribing air standards, within the geographic area of the local board's jurisdiction or any part thereof."
The Air Board consists of seven voting members who volunteer and are appointed to serve on the Board. Four members are appointed by the Mayor of the City of Albuquerque, with the advice and consent of the City Council, and three members are appointed by the Bernalillo County Commission. There are also two non-voting members who are representatives from the City's Environmental Planning Commission and the County Planning Commission respectively. Members of the Air Board shall be appointed for three-year terms. No member shall serve more than two consecutive terms at a time.
A rulemaking hearing before the Air Board is a hearing to adopt, amend or repeal a board rule, regulation or standard. Procedures for this type of hearing are delineated in. Rulemaking procedures do NOT apply to adjudicatory actions.
An adjudicatory hearing before the Air Board is one in which the Board makes a final, binding determination that directly affects the legal rights of Air Quality permit applicants, permittees or other persons who participated in a permitting action before the Department and who are adversely affected by the permitting action. Procedures for this type of hearing are delineated in. Adjudicatory procedures do NOT apply to rulemaking actions.
All hearing records, including exhibits and hearing transcripts, are available from the City of Albuquerque Environmental Health Department in the Control Strategies Section of the Air Quality Division, which serves as the administrative agency for the Air Board. Please e-mail _EMAIL_ for any information.
The regulations contained herein have been adopted by the Air Board. These regulations apply to private and public sources of air pollution in Bernalillo County, New Mexico. The Air Board's jurisdiction does not include tribal lands (excepting 20.11.3 NMAC). Regulations are adopted by the Air Board after a public hearing is advertised and held in accordance with State law. Adopted regulations are filed with the New Mexico State Records Center, and are codified into the New Mexico Administrative Code (NMAC).
Note that these regulations are updated periodically and new regulations are adopted occasionally. Air quality regulations that apply to New Mexico counties other than Bernalillo County are adopted by the New Mexico Environmental Improvement Board.
The New Mexico Environment Department's Air Quality Bureau in Santa Fe can be contacted for more information about the non-Bernalillo County regulations.
To contact the Air Board please call Margaret Nieto, Secretary to the Air Quality Control Board at _PHONE_ or email _EMAIL_.
Air Board Meetings are usually held on the second Wednesday of each month, at 5:30pm, in the Vincent E. Griego Chambers, Albuquerque-Bernalillo County Government Center, One Civic Plaza.

The Rev. Dr Richard Temple West (_PHONE_), Clergyman & Social Reformer
Described as "one of the most prominent and respected of the High Church Clergy of the (London) metropolis" (The Times, 11/02/1893:10), Richard Temple West was the first vicar of St Mary Magdalene's Church in Paddington and the instigator of its initial vision, architectural realisation and ongoing mission. As the son of J.M West, a Commissioner of Bankruptcy and Lady Maria Walpole, daughter of the Earl of Orford, Rev. West came from privileged origins. His education at Christ Church, Oxford, was followed by ordination 1853 and early work in provincial parishes. In 1865 he became curate of the Church of All Saints, Margaret Street, a formative experience that would go on to inform and inspire the remainder of his life's work at St Mary Magdalene. He became a passionate advocate for improving the plight of the poor through Christian ministry in the dense, urban setting of London. In 1874 he received a Doctor of Canon Law Degree from the University of the South, U.S.A and later joined the council of Keble College, Oxford. West died in Bournmouth in 1893.

Can I use V-LFP batteries for hexacopter?
What are V-LFP batteries? Do you mean lithium iron phosphate batteries (LiFePO4 batteries)? I don't think I've seen LiFePO4 batteries referred to as V-LFP batteries before.
LiFePO4 batteries have some pretty cool properties and it would be nice if they could be used in UAVs. After investigating this a bit, I think I've come across a few problems when using LiFePO4 batteries in UAVs.
- (Probably the biggest.) LiFePO4 batteries have a lower energy density than Li-Ion or LiPo batteries. You'll have reduced flight times when using LiFePO4 batteries compared to LiPo batteries.
- LiFePO4 batteries generally can't produce the same about of current as LiPo batteries. LiFePO4 batteries have a lower "C" rating than their LiPo conterparts.
- Another issue with LiFePO4 batteries is keeping track of how much charge you have left. LiFePO4 batteries don't have the same discharge curve as LiPo batteries. You need to monitor the current when using LiFePO4 cells to compute how much power has been used. You can't simply measure the voltage of LiFePO4 batteries to get an idea of how much power you have remaining.
It might be possible to use LiFePO4 batteries in an airplane which doesn't draw a lot of current but I think the C ratings on LiFePO4 batteries would make them inappropriate for quadcopters or hexacopters.
If you're not asking about LiFePO4 batteries, then what sort of batteries are V-LFP batteries?
There has been a mistake. I was talking about LiFePO4 batteries. Thank you for the information.
They're interesting batteries. I'd really like to use them to power UAVs myself but as I mentioned before, I think the batteries would only work well in a low current application such as a long range airplane.
LiFePO4 batteries would probably be a good solution for a lot of land based robots. I purchased a bunch of 32700 cells which I hope to use in a rover. I might try using them to power an airplane.
I'm waiting for your results if you try
I'll try to remember to post an update here when/if I get around to doing this.
I'm by no means an expert on the subject of these batteries but based on a few videos I've watched, I believe these require specialized charging circuits.
I purchased two of the "4-6S NCM LFP LTO" boards from this seller:
Apparently these balancers don't don't waste as much power as other balancing boards.

In an effort to bolster our ability to identify some of New Zealand's most widespread and commonly cultivated trees, Leon Perrie, Curator of Botany and I attended a workshop for identifying Eucalyptus, Corymbia and Pinus species this month.
The workshop was presented by Chris Ecroyd, a long standing member of New Zealand's botanical community who worked as Curator of New Zealand's Forest Research Institute Herbarium (NZFRI) at Scion NewZealand, before retiring last year. The workshop was also supported by Scion and Wellington City Council.
Eucalyptus and Corymbia are part of the family Myrtaceae. Commonly known members of this family native to New Zealand include rata and pohutukawa (Metrosideros species), kanuka (Kunzea species) and manuka (Leptospermum scoparium). However the Australian members of the Myrtaceae family are much more difficult to tell apart, principally because there are so many of them.Mallee is the term used to describe a gum that is a shrub or tree less than 10m in height and is multi-stemmed from ground level. We learnt that all mallees are in the Eucalyptus genus, like Eucalyptus stricta above, although these would be rare or non-existent outside gardens in New Zealand.
Chris presented tips for collecting good specimens, with mature seed capsules (for Eucalyptus and Corymbia) and mature cones (Pinus) being the best (but not only) material to collect to aid identification. New knowledge for us was that specimens of Pinus are best collected in mid-winter when winter resting buds are present. It's also important to collect open and closed pine cones, if possible, and note direction of growth on the branch and whether or not they are retained on the tree after maturing.
Discipline with note taking is important when collecting any specimen and these genera are no exception. It's important to try to remember to note bark colour, texture and the general tree habit, among other things.
We were also taught characteristics used to split each genera into sub-groups and introduced to computer-based, interactive keys for both Eucalyptus and Pinus. Interactive keys are becoming a more widespread tool for identifying a number of genera. See a demonstration of how the Eucalypt EUCLID key works.
The EUCLID software has to be purchased, but the key to cultivated pines in New Zealand is freely available at key to cultivated pines. Ensure that you have 'pop-ups' enabled on your computer and that you install version Java Virtual Machine v1.4.2 or later.
The identification skills we picked up at the workshop will enable us to develop the collection of these genera within Te Papa's herbarium (WELT). At WELT we are interested in collecting cultivated plants as well as native plants and have a responsibility, as part of New Zealand's herbaria community, to collect representatives of all known cultivated species within the central New Zealand region. This group still requires significant development at WELT.
Thanks to Jean-Claude Stahl, Te Papa for editing these images.

Fixing Potholes with Non-Newtonian Fluid
potholes? Forget waiting around for 5 road workers to stand around and watch
while one guy fills the pothole with asphalt! Just grab a bit of non-Newtonian
fluid and, there – you fixed it:
The students, undergraduates at Case Western Reserve University
in Cleveland, devised the idea as part of an engineering contest sponsored
by the French materials company Saint-Gobain—and took first prize
last week. The objective was to use simple materials to create a novel
"So we were putzing around with different ideas and things
we wanted to work with—and we were like, what's a common, everyday
problem all around the world that everybody hates?" explains 21-year-old
team member Curtis Obert. "And we landed on potholes." He
and four other students decided on a non-Newtonian fluid as a solution
because of its unusual physical properties. "When there's no force
being applied to it, it flows like a liquid does and fills in the holes,"
says Obert, "but when it gets run over, it acts like a solid."
What? Don't believe us? Check out this video clip of people
walking on water in a pool filled with non-Newtonian liquid.


Using Modifiers
Modifiers are small scripts which can hook in to the Seeker and pre and or post process the path before it is returned to the caller.
Modifiers are used by simply attaching the scripts to the same GameObject as the Seeker component is attached to. They will work automatically without any code modifications.
This can for example be a Raycast Modifier which removes unecessary nodes in a path to make it shorter but still valid. Or a Smooth Modifier which subdivides the path and smooths it to make it more aesthetically appealing.
Below is a comparison of a few of the most common types of modifiers/combination of modifiers on a grid graph.
The AIPath and AILerp movement scripts use modifiers however the RichAI movement script will ignore most of them (all that smooth and simplify the path). The RichAI movement script instead includes its own internal version of the funnel modifier which is slightly more specialized for the RichAI script. You can still attach other modifiers when using the RichAI movement script.
Simple Smooth Modifier
The simple smooth modifier is a modifier to smooth the path. It can do that either by just subdividing it and moving the vertices closer to each other or use splines, namely the Bezier curve.
Below are two images showing a path with the smooth modifier turned off first and then on. Note that the smoothed path cuts the corners a bit, this can be a problem with the smooth modifier since it does not take world geometry into account when smoothing. For variable documentation, look at the Simple Smooth Modifier documentation
Funnel Modifier
The funnel modifier is a modifier for simplifying paths on navmeshes or grid graphs is a fast and exact way.
As the name implies it applies the funnel algorithm to the path.
This will return the shortest path inside the path corridor the pathfinder calculated
You can see a list of all modifiers if you click on Modules above and go to "Modifiers".
Raycast Modifier
The raycast modifier simplifies paths by doing a series of straight line checks. This modifier is primarily useful on grid graphs, though depending on your game it can be useful if you are using a point graph too.
Custom modifiers
It is also possible to write your own path modifiers.

Electron ring images confirm Landau Levels
U. WARWICK (UK) — Physicists have directly imaged Landau Levels for the first time since Nobel Prize-winner Lev Landau conceived of them in 1930.
Landau Levels are quantum levels that determine electron behavior in a strong magnetic field.
Using scanning tunneling spectroscopy—a spatially resolved probe that interacts directly with the electrons—scientists at institutions including the University of Warwick and Tohoku University have revealed the internal ring-like structure of these Landau Levels at the surface of a semiconductor.
In the image, electrons form concentric rings, which increase in number according to their energy level. (Credit: U. Warwick)
Straight from the Source
The experimental challenge in the work was to have sufficient spatial resolution in order to overcome the intrinsic disorder in the material which usually only allows the observation of smeared out "drift" states.
The images clearly show that Landau was right when he predicted that, in a clean system, the electrons would take on the form of concentric rings, the number of which increase according to their energy level.
This simple counting behavior forms the basis of the so-called quantum Hall effect.
While originally of mostly fundamental interest, more recently the effect has been used to define the standard for what we mean by electrical resistance and could soon be employed to define the kilogram as well.
"This is an exciting step for us," says Professor Rudolf Roemer of the department of physics. "We are really seeing for the first time individual quantum mechanical wave functions of electrons in real materials.
"On the face of it this might seem far removed from everyday life. However the question of what defines a kilogram is currently being debated, with the spacing between the rings of these Landau levels acting as a kind of marker for a universal weight.
"So next time you measure out your sugar to bake a cake, you might unknowingly be making use of these quantum rings."
The research was published in the journal Physical Review Letters.

Detailed Description
An interval is specified by an inclusive start() and end() time. These must be set in the constructor, as this is an immutable class. The specific units of time represented by the class have not been defined - it is suitable for any times which can be represented by a signed 64 bit integer.
The isNormal() method determines if a time interval is normal (a normal time interval has start() <= end()). A normal interval can be received from an abnormal interval by calling the normalized() method.
The contains() method determines if a specified time lies within the time interval.
The translated() method returns a time interval which has been translated forwards or backwards through time by a specified offset.
See also QMediaTimeRange.

The Benefits and Advantages of Frequency Response Simulation in PCB Design
November 19, 2019 Cadence PCB Solutions
Collection of types of signals and waveforms
I often hear the question, does frequency really matter? Whether it is in the context of car audio, home audio, or PCB design, yes, frequency matters. The frequency response of any device that requires a particular resonance is vital to the overall design and performance of the device in question.
For example, I recall redesigning a car audio system for someone a few years ago. The recipient of this redesign was currently suffering from shock-induced anger, after spending $2,000 on a pair of subwoofers and an enclosure. It was not the price that had him up in arms, but rather the fact that his car was still reeking of the smell of burnt coils from an improper install.
Even in car audio, simulation is the key to proper design. Well, in this case, it's apparent that simulation was not part of the plan. The end result was him being embarrassed while demonstrating his new stereo via an epic YouTube fail. These are the types of situations that simulation can and will effectively help you to avoid. Whether you are tuning a bandpass enclosure or designing circuits for a PCB, frequency simulation is the key.
The Importance of Frequency Response Simulations
As a science fiction fan myself, I have seen my share of time-travel related movies, and they always seem to end the same. However, after viewing these movies, I always find myself asking the proverbial question; what if? The ability to know the outcome before the event even happens is one of the critical advantages of simulation software.
In terms of frequency response, simulations provide you with the ability to accurately predict the response of your circuit before you build it. Another advantage to this is, of course, it saves time, lowers cost, and it perfects your design. Furthermore, it also fosters innovation and advances the design process by allowing you to examine various models and configurations.
The Benefits and Advantages of SPICE Simulation
Across multiple sectors, fields, and disciplines, simulation is having a profound positive effect. Ask any engineer, and they will tell you that simulation software is an invaluable design tool. In terms of PCB design, simulation as a whole is the choice between designing your PCB correctly, and a science experiment that has gone wrong.
One of the primary advantages of using simulation software is the fact that it enables you to obtain valuable feedback when designing real-world circuits. Furthermore, this feedback does not come with the time or expenditure typically required to procure this much-needed design insight. This, in turn, allows the designer to determine the efficiency and correctness of their designs without the need to build the circuit or device first.
As a result, simulation software also allows the designer to explore the worthiness of alternate designs without ever building the actual device or circuit. Moreover, examining the effects of your design decisions during the design phase rather than the construction phase, saves time, money, and increases design quality.
Green representation of digital waveform
Digital signals mixing with analog signals have unique properties.
SPICE Simulation Software and Frequency Response Simulations
When using SPICE, it allows you to place probes and generate waveform plots for further analysis. This is made possible by its ability to determine intricate branch currents and node voltages at each frequency across your entire design.
Some of the primary functions SPICE can perform are as follows:
 - DC Sweep: Allows for the changing of component values (resistor value, voltage, or current) and graphing the results.
 - AC Sweep: Performs an analysis of the frequency response of a circuit (phase and gain).
 - Transient Analysis: Affords you the ability to set a period of time and analyze the response of your circuit within this timeframe.
 - It is worth noting that PSpice can provide an even more in-depth analysis of your circuits and circuit designs. The previously mentioned functions are only a part of what PSpice can afford you. The following are the other more advance simulation functions PSpice provides.
 - Sensitivity: Variations in manufactured components are natural. Sensitivity analysis lets you test circuit performance across the minimum and maximum tolerances for different component values and identify which elements are critical to your design goals.
 - Monte Carlo: Perform statistical Monte Carlo analysis on multiple components varied across their tolerance ranges to help predict your production yield under different conditions. This can be used to identify which parts can have their tolerances widened, reducing cost without sacrificing performance.
 - Smoke (Stress): Identify increases in junction temperature, secondary break-downs, power dissipation stresses, and voltage/current violations throughout your design.
 - Optimizer: Automatically optimize analog circuits and systems to find the best component values for your performance goals and constraints.
 - Parametric Plotter: Analyze/sweep multiple design and model parameters at once in plot or tabular form.
So, what type of simulation do you typically use for frequency response simulations? Well, the short answer is, a time domain simulation is ideal.
Graphic frequency waveform representation
SPICE can help with many aspects of your circuit design
Using Time Domain Simulations to Simulate Frequency Response
In regards to simulation software, time domain is the standard method for examining the behavior of an output signal for a given input signal (response). There are several reasons for this. First of all, when using time domain, you can calculate the current and voltage numerically across the entire circuit.
Secondly, you can examine the transitory behavior of a circuit to either a step response, like an input voltage switching from off to on or an impulse, such as a delta function input signal.
Finally, it affords you the ability to examine the response of a signal to a random input signal. You also have the option of using any input signal you choose as well as have these signals be a (repeating) waveform such as a triangle wave, digital pulse, or sawtooth wave. Also, you have the option of overlaying the input and output voltages to assess how the circuit influences the input signal. Furthermore, you gain a greater understanding of how a circuit performs when you examine the effects of input signal changes.
Frequency response simulations, like all simulations, are a vital part of PCB design. The use of simulations provide lower costs, saves time, increases design decision accuracy, and improves overall design quality. Having the ability to accurately predict the performance of an electronic circuit or device is an option every designer should utilize.
Alternatively, there are also AC simulations like AC sweep analysis wherein you can measure voltage and current changes with frequency. An AC sweep will enable you to calculate voltage and currents across a range of frequencies. Typically you will use a voltage source with an amplitude of 1V and use probes to generate the plots you need.
What is PSpice Simulation?
If you are like me, you probably have a couple of breadboards lying around, and believe me; they were once an invaluable tool. In some cases, they still have their uses, but overall, when addressing frequency response, simulation is the way to go.
In PCB design, obtaining an accurate frequency response throughout your circuit design is critical to the overall functionality of the PCB. With that in mind, the advantages and benefits of simulation (PSpice) software is a crucial part of ensuring proper design outcome.
So, what is PSpice? PSpice is an acronym for Personal Simulation Program with Integrated Circuit Emphasis. In a more generalized description, it is an electronic circuit simulation tool (Cadence). During operation, PSpice will typically utilize a netlist generated from an OrCAD Capture. However, there is an option to operate it from MATLAB/Simulink. In summary, PSpice allows you to analyze as well as simulate your mixed-signal and analog circuits within OrCAD.
Cadence's design and analysis tools, are sure to have your designers and production teams working together towards implementing frequency response simulation solutions for all of your PCB designs. OrCAD PSpice Simulator facilitates the implementation of frequency response simulations for all of your electronic circuit design needs, as well as many other types of simulation to ensure top design security.

I don't see how you draw the inference you draw. Clearly, P(B|A) and P(A|B) are constituent probabilities as well.
 Show how to derive P(A and B) given P(A) and P(B). If you > can show that, you can claim that "probability depends only on the > constituent probabilities". Are you unable to do that?
P(A and B) = P(B|A)P(A)
P(A and B) = P(A|B)P(B)
To derive P(A and B) one must know either P(B|A) or P(A|B) just as one must know the angle between two sides to use the cosine law. You fail to demonstrate anything useful or meaningful by your challenge.

Keith already specified the argument applies to a limit.
>>P(A) = 1
>>P(A or B) = P(~(~A and ~B))
>>P(A or B) = 1 - P(~A and ~B)
>>P(A or B) = 1 - P(~B|~A)P(~A)
> Since P(~A) equals zero, the above statement does not make sense.
But Keith stated "in the limit of". Thus, one could read the first line of what he wrote as
lim P(A) as P(A) -> 1
which makes the other factor
lim P(~A) as P(~A) -> 0.
Thus, in the limit as P(A) approaches 1, P(A or B) = 1 - P(~B|~A)(1-P(A)) = 1
If he rewrote the proof using explicit limit notation, would you still object to his proof? Received on Sun Jun 11 2006 - 20:12:22 CDT

Planning During the Internship: A Study of the Planning Practices of Preservice English Teachers
Hessong Grove, Rebecca M.
MetadataShow full item record
This collective case study investigated the planning practices of six English education interns during the full time internship, including planning for edTPA. Research and professional standards emphasize the importance of planning, as it undergirds every aspect of what happens in a classroom. By understanding how interns learn to plan, teacher educators can better facilitate interns' development of planning skills. Using activity theory as a theoretical framework, this study describes how interns' planning practices changed over the course of the internship and identifies factors that influenced changes. Data sources included lesson plans, interviews with interns and mentors, and edTPA lesson plans. Findings showed most interns did not write detailed daily plans, but those who did experienced fewer planning and teaching struggles. Communication and feedback from the mentor were major factors in creating successful plans and planning routines. Three of the interns began writing more detailed plans to improve their teaching, motivated by a desire to be more organized and effective. All interns wrote detailed, formal plans for edTPA, and these plans included elements that were not part of typical written plans, such as differentiation and formative assessment. Other areas of change included increased planning for scaffolding and addressing students' confusion. Graduate interns expressed increased confidence in planning student-centered lessons. Factors that influenced such changes included experience, mentor guidance, and support from a methods course. Interns also drew on their increasing knowledge of students and district curriculum to plan relevant lessons. Interns consistently planned at the whole-class level, with little evidence of planning for individual learning. This study has implications for teacher educators aiming to strengthen candidates' planning practices. Programs must facilitate proactive mentoring and structured co-planning. Pre-service coursework should help candidates integrate student-centered pedagogy, formative assessment, and differentiation into lesson plans. The impact of internship length and undergraduate vs. graduate program structures must be investigated further. Finally, this study indicates that planning for edTPA was educative for interns. This, along with other findings, suggests that more formal planning can improve intern learning and program coherence.

Review: Te Ata
Te Ata was the stage name Mary Thompson Fisher took on in 1919 when she left her Chickasaw home in Oklahoma to pursue a career in acting. The film is the inspiring story of her journey to becoming a renowned storyteller who brought the stories of Native Americans to the white population. Played beautifully by Q'orianka Kilcher, Te Ata was a true pioneer, breaking barriers and humanizing her people at a time when the government was still actively trying to suppress their culture. The film lays the racist politics out clearly, but focuses on the story of the unheralded hero. Girl power!

Laura J. Martin, MD
Feb. 23, 2011 -- Electricity alone may be enough to zap sweaty palms and temporarily relieve excessive sweating caused by hyperhidrosis.
A new study shows that applying a small electric current to the wrists of people with the disorder kept their hands dry during treatment.
Researchers say tap water iontophoresis, which involves placing hands in a container of tap water charged with an electric current, has been a common treatment for hyperhidrosis for many years. But the results of this study suggest that the tap water may be unnecessary and a dry electric current alone may be an effective treatment for sweaty palms.
"These results imply that tap water in traditional iontophoresis may play no other part than acting as conductor for current," researcher Kave Shams, MBChB, of Monklands Hospital in Airdrie, Scotland, and colleagues write in the Archives of Dermatology. "This suggests that far less bulky iontophoresis machines requiring less space and resources could also be effective, although further studies are required to verify this proposition."
The study evaluated the effects of applying a low-level electric current via battery-operated pads to the wrists of six people with sweaty palms (palmar hyperhidrosis). Researchers applied a special solution to make sweaty areas appear dark blue and then photographed the participants' hands before, during, and after the two-minute electrical treatment.
The results showed that the dry electric current led to a substantial reduction in sweating during treatment, and the sweating returned within seconds or minutes after the electric current stopped.
The participants also subjectively rated their sweaty palms during treatment on a scale of 1 to 100 (dry to wet) and reported a reduction from an average of 66.2 before treatment to 19.2 during treatment.
The study results may help researchers better understand the mechanisms behind the disorder and develop more effective treatments.

Richard King "The Lark Ascending"
Over the course of the twentieth century, The Lark Ascending by Ralph Vaughan Williams is the piece of music that has come to define the mythical concept of the English countryside, with its babbling brooks and skylarks. Yet, the landscape is not really an unaffected utopia, but a living, working and occasionally rancorous environment that has forged a nation's musical personality. On a journey that takes us from post-war poets and artists to the free party scene embraced by the acid house and travelling communities, Richard King explores how Britain's history and identity have been shaped by the mysterious relationship between music and nature.

Povzetek. Let G=(V(G),E(G)) be a simple graph. A set S ⊆ V(G) is a strong edge geodetic set if there exists an assignment of exactly one shortest path between each pair of vertices from S, such that these shortest paths cover all the edges E(G). The cardinality of a smallest strong edge geodetic set is the strong edge geodetic number of G. In this talk, the strong edge geodetic problem is studied on the Cartesian product of two paths.
