Exact Power SP15EU
The ExactPower SP15A has been designed to isolate and reduce unwanted noise from your audio/video front-end equipment for improved picture and sound quality. The unique feature of the SP15A is a single, oversized 1800 watt transformer, powering eight output receptacles.
The ExactPower SP15A provides 15 Amps of symmetrical power. The voltage on the output receptacles is symmetrical around the earth ground. The „Line" and „Neutral" are of equal voltage and opposite polarity or phase. The voltage is 60Vac on each side of ground, so that the total output is USA standard 120Vac.
Critical to the SP15A is the design and manufacturing process of the transformer. At ExactPower we design and manufacture all our own transformers in-house in the USA, and we utilize only the best materials and highest-quality workmanship. This ensures that transformers meet our stringent specifications and perform to their full potential. The kind of transformer used in the SP15A is toroidal — the only type that can give the best results. The transformer must provide isolation, noise reduction, and inaudible acoustic noise. The transformers are wound with a proprietary symmetrical layering method. This method reduces the „Common Mode Noise" that is present on both incoming „Line" and „Neutral." An electrostatic shield is placed between the primary (input) side and the secondary (output) side of the transformer. This reduces noise by using a copper strip that is connected to the earth ground. High frequency noise on the primary is shunted to the shield and then to ground, so it never reaches your components. Precision winding provides for a consistent transformer.
There are two units to choose from: one without the EMI and RFI filters to be used in conjunction with the EP15A, and one with the filters to be used as a stand-alone product. Although the unit with filters can be used with the EP15A, the filters are redundant since the EP15A incorporates these filters. The SP15A also incorporates filters for digital equipment on four of the receptacles. These filters block any digital noise that may be present on the power line of a digital product from contaminating other products powered by the SP15A.

The Bigger Picture: Visual Archives and the Smithsonian
Now Open to the Public (in 1922) - Museum of the American Indian
On November 14, 1922, George Gustav Heye opened to the public the Museum of the American Indian, Heye Foundation in New York City to display his collection of Native American artifacts. Heye, a mining engineer, began collecting Native American artifacts while working in Arizona in 1896. The museum, founded in 1916, was located at Audubon Terrace and there was also a research branch in the Bronx where collections were available for research and study.
After Heye's death in 1957, the future of the museum was in doubt. Some thoughts were to transfer the collection to the American Museum of Natural History in New York or possibly for it to be purchased by businessman, H. Ross Perrot. Neither of these options came to pass.
It was not until the 1980s when discussions began with the Smithsonian that a home would be found for the Museum of the American Indian. On November 18, 1989, President George H. W. Bush signed legislation creating the National Museum of the American Indian as part of the Smithsonian. Today the museum consists of the George Gustave Heye Center in New York City (unfortunately because of Hurricane Sandy the Heye Center is temporarily closed), the Cultural Resources Center facility in Maryland, and the museum on the Mall in Washington, D.C.

Special Issue on Papers from the 1st International Conference on Structural Adhesive Bonding (AB2011), Porto, Portugal, 7-8 July 2011. The Journal of Adhesion. [Resumen]. The inclusion of particles (nano or micro) is a method to improve the mechanical properties, such as toughness, of structural adhesives. Structural adhesives are known for their high strength and stiffness but also for their low ductility and toughness. There are many processes described in the literature to increase the toughness, one of the most common being the use of rubber particles. In the present study, natural micro particles of cork were used with the objective to increase the impact resistance of a brittle epoxy adhesive. The idea is for the cork particles to act like crack stoppers and absorb impact leading to higher absorption of energy. The influence of the cork particle size and amount were studied. Particles of cork ranging from 38 to 250 µm were mixed in the epoxy adhesive Araldite® 2020 from Huntsman. The amount of cork in the adhesive was varied between 1 and 5% by weight. Surface treatment (low pressure plasma) was applied to the cork powder to assess the effect of the interaction adhesive-cork with several degrees of adhesion. This evaluation was made using impact tests and it was evident that impact absorption was related to the size and amount of cork particles in the resin, considering a uniform particle distribution.

Problem: Suppose that $f:S^n\to S^n$ is a mapping from the n-dimensional sphere ($n\geq 3$) into itself which maps circles into (instead of onto) circles. Can we say that f maps (n-1)-dimensional spheres into (n-1)-dimensional spheres?
Here, we make no any other assumption on f, e.g. continuity, injectivity, surjectivity, and so on. Circle is in the ordinary sense, i.e. round circle (or say 1-sphere), not necessarily great circle.

In your questions are you assuming continuity? – alvarezpaiva Dec 28 '12 at 20:14
I don't see why this is tagged soft-question. – HJRW Dec 28 '12 at 20:15
_USER_: do you have an example of a map that sends circles into circles, but which is not a Moebius transformation? – alvarezpaiva Dec 28 '12 at 20:36
_USER_: Take any map which sends sphere to the circle. – Misha Dec 29 '12 at 4:53
What is a "circle" for your purposes -- great circle, round circle, or perhaps something else? – Ryan Budney Dec 29 '12 at 6:09
1 Answer 1
Take two circles $C_1, C_2$ intersecting in two points $p_1, p_2$. These are contained in a unique 2-sphere $S$. One way to see this is to assume $p_1=\infty$, $S^n-p_1=\mathbb{R}^n$ (considering $S^n$ as the one-point compactification of $\mathbb{R}^n$). Then the circles $C_1, C_2$ correspond to two lines intersecting in a point $p_2$, which span a unique 2-plane in $\mathbb{R}^n$ corresponding to the sphere $S$.
The images $f(C_i)\subset D_i$, where $D_i$ are circles, and $D_1\cap D_2 = \{f(p_1),f(p_2)\}$. Let $T$ be the unique 2-sphere containing $D_1\cup D_2$. Then I claim $f(S)\subset T$. Normalize it by post-composition with a Moebius transformation so that $f(p_1)=\infty$, then any line intersecting $(C_1\cup C_2)-\infty$ in two points distinct from $p_2$ will map to a line intersecting the lines $D_1\cup D_2-\infty$ in two points, and thus is contained in $T$. So $f(S)\subset T$ since every point of $S$ is contained in a line intersecting $D_1, D_2$ in points distinct from $f(p_2)$.
One can perform a similar inductive argument to show that higher-dimensional spheres are preserved. Take $k$ circles intersecting two points, say $0, \infty$, which span a $k$-plane $K$ in $\mathbb{R}^n$. Then any point on $K$ is contained in a $k-1$-plane $J$ intersecting the $k$ lines in points different from the origin. Then the image is contained in a similar configuration by induction, so the $k$-spheres are taken to $k$-spheres.
share|cite|improve this answer
Your argument requires that the inverse image of $p_1$ (or say $\infty$) consists of a single point. So, you can not reduce the question to $\mathbb{R}^n.$ – woodbass Dec 31 '12 at 2:29
_USER_: Actually, Agol's arguments (with minor corrections) suffice. Also, a much more general result is Theorem 4.8 in – Misha Jan 1 '13 at 0:31
I do not think so. Please think of: Why f cannot map $S^2$ exactly to 5 points which is not in a 2-sphere and no four of which lie in a circle? – woodbass Jan 1 '13 at 8:04
Of course, if assume injectivity, the situation reduced to R^n. There are essential gaps in MaCcallum's thesis as I noted in another comment (see:…). I do not know how to add a simple super-link to that comment. – woodbass Jan 1 '13 at 8:26

circuit riderArticle Free Pass
circuit rider, Methodist ministerial role that was originated in England by John Wesley. The first of the American circuit riders was Robert Strawbridge, who arrived in the colonies in 1764. A few years later Wesley sent missionaries to the American colonies, but most of them departed when revolution threatened. One who remained was Francis Asbury, who, as Wesley's general assistant, was responsible for organizing the circuits.
Each circuit of congregations—sometimes comprising as many as 25 or 30 meeting places—was under the supervision of a Methodist conference preacher who might have several lay assistants. Any young man who could preach and was willing to ride a horse for weeks over wild country might become an assistant and finally a circuit rider. Circuit riders numbered about 100 by the end of the American Revolution. The salary was $64 a year until 1800, when it was raised to $100, with the horse furnished. There were few actual meetinghouses; church services usually were held in cabins, in barrooms, or outdoors.
Circuit riders were a religious and moral force along the frontier and in rural areas of the South, and they were largely responsible for the propagation of Methodism throughout the United States. The practice was soon adopted by other denominations, too.

Analysis and Synthesis of Head Motionfor Life like Conversational Agents
Kawamoto, Shin ichi
Hofer, Gregor O
MetadataShow full item record
This study aims to investigate which and what motions of lifelike conversational agents play essential role to make the agents natural. Some preliminary experimental results and future plan are shown. Embodying conversational agents is intended to imitate paralinguistic channel or back channel which plays important role in human-human conversation. Although there have been not a few lifelike conversational agents developed, appearance and behaviour of the agents are far from being natural, and merits of embodying have not been realized that much. One of the main reasons is the lack of natural motions of the agents, including the motion of head, mouth, eyes and eye brows. To improve the quality of these motions, several pioneering works have been reported [1–3]. To tackle the problem, the present study was started conducting a subjective test of head motion and analysis of head motion using signal processing techniques.

Finance and Trading Terms Explained: What Is a Head-and-Shoulders Pattern?
Even professional traders and investors can't always speak the language of colleagues working in a different segment of the financial world. With that in mind, we've introduced this weekly column, looking at one esoteric or potentially misunderstood finance or trading term every week. After bringing you "carry trade," "contango," and "reflation" in past columns, we'll now focus on a term from the world of technical trading: the head-and-shoulders pattern, sometimes shortened to HASP.
What Exactly Is the Head-and-Shoulders Pattern?
The short answer: It's a pattern in an asset's price movement that literally looks like a head and shoulders on the asset's price chart. The pattern is important to traders because it generally signals a drop in price. We asked Braden Perry, COO of the broker dealer Kennyhertz Perry, to help explain what this means. As he told us, "The general head-and-shoulders pattern begins with the left shoulder, which includes a price increase, peak, and then decrease. The head begins on the following price increase forming a higher peak, then is followed by the right shoulder, showing a lower price peak."
Below is an illustration of this pattern:
A reverse head-and-shoulders pattern can also happen, where a bottom head and shoulders signals that a price increase will likely be the ultimate outcome. Below is an illustration of the reverse head-and-shoulders pattern:
How Can Traders Profit From the Head-and-Shoulders Pattern?
To give an example, a trader will watch for patterns like the head and shoulders to form in an asset stock of, say, Apple (NASDAQ:AAPL). When a head-and-shoulders pattern does form, a trader can assume that the value of Apple's stock is going to decrease upon the completion of the pattern. So the trader will short-sell Apple stock to make a profit. Conversely, another trader watching for patterns in, say, Google (NASDAQ:GOOG) may notice a reverse head and shoulders and buy shares of Google, expecting the stocks price to increase.
There's no defined time frame for the pattern, meaning it can occur over a course of days or months. "Many day traders and short-term traders utilize the pattern, as well as technical and long-term investors," said Perry.
Can the Head-and-Shoulders Pattern Be Relied Upon?
"The head-and-shoulders pattern is one of the more reliable [indicators], both in reversals and in uptrends, in traditional equity stocks, but it has been recently invalidated by several commodity stocks, including silver and platinum," said Perry.
However, some consider the reverse head-and-shoulders pattern to be weaker than the standard HASP. In his book How to Make Money in Stocks, William O'Neil, the founder and chairman of Investor's Business Daily, says, "A head-and-shoulders bottom may succeed in a few instances, but it has no strong prior uptrend, which is essential for most powerful market leaders."
Still, O'Neil admits that the head-and-shoulders top is one of the most accurate patterns that a trader can use. One mistake that's sometimes made, however, is that some traders don't pay close enough attention to the shoulders. "Watch carefully where the shoulders form," said Paul Whitfield, an Investor's Business Daily writer. "The right (second) shoulder must be slightly below the left shoulder. A lower right or second shoulder is much more indicative of a downward trend than when it is higher."
Whitfield also takes issue with the so-called "neckline," a trend line that's sometimes drawn touching the lows of the pattern. In a case where a neckline is used (see the image above of the inverted head-and-shoulders pattern), the trader shorts the asset when its price drops below the neckline. On this error, Whitfield writes, "This, however, is an obvious signal and sometimes doesn't work. Instead, it more often pays off to wait until the stock has made a sharp break below its 50-day moving average. Usually this occurs after attempting a few rallies back above the 50-day line." Most trading platforms will allow you to place an asset's 50-day moving average on the same chart as its price, for comparison.
Click here for an illustration of Whitfield's point on a price chart for Alexander and Alexander Services, an insurance brokerage firm that was acquired by Aon (NYSE:AON) in 1996.
Why Exactly Does the Head-and-Shoulders Pattern Offer a Signal That an Asset Price Will Drop?
It's not stock market trading magic, so what is it? As Braden Perry told us, "Its pattern follows the natural rationale that there are bullish and bearish trends, and this is a microcosm of the markets generally."
The head-and-shoulders pattern works because it signals a top to an asset price, a ceiling through which the price of that asset is not likely to rise. The top is the beginning of a downtrend, so traders can be fairly confident that a proper head-and-shoulders pattern is signaling a drop in price.

In chapter 3.3. Property Characteristics written:
If a property, P1, is tagged as the owl:inverseOf P2, then for all x, y, and z:
P1(x,y) iff P2(y,x)
Note that the syntax for owl:inverseOf takes a property name as an argument. A iff B means (A implies B) and (B implies A).
1) imho it is better to write simply "for all x and y" (without z)
2) but below in explanation of InverseFunctionalProperty there is written vice versa "for all x and y" but need x,y,z

]] {
 def onInput(cont: Step[Byte, Seq[Byte]] => Future[B]) = step(Step.Done(data, Input.Empty))
 case Input.Empty => this
One big difference here that you now notice is when we receive EOF, we actually pass Done into the step function, to say we are done consuming the input.
And so now we've built our iteratee interface. Our naming isn't quite right though, so we'll rename the trait obviously to Iteratee, and we'll rename onInput to fold, since we are folding our state into one result. And so now we get our interface:
trait Iteratee[E, +A] {
Iteratees in practice
So far we've started with the requirements of a traditional imperative input stream, and described what an iteratee is in constrast to that. But looking at the above code, you might think that using them is really difficult. They seem like they are far more complex than they need to be, at least conceptually, to implement reactive streams. Well, it turns out that although so far we've shown the basics of the iteratee interface, there is a lot more that a full iteratee API has to offer, and once we start understanding this, and using it, you will start to see how powerful, simple and useful iteratees are.
So remember how iteratees are immutable? And remember how iteratees can be in one of three states, cont, done and error, and depending on which state it's in, it will pass its corresponding step class to the folder function? Well, if an iteratee is immutable and it can be in one of three states, then it can only ever be in that state that it's in, and therefore it will only ever pass that corresponding step to the folder function. If an iteratee is done, it's done, it doesn't matter how many times you call its fold function, it will never become cont or error, and its done value will never change, it will only ever pass the Done step to the folder function with the same A value and the same left over input. Because of this, there is only one implementation of a done iteratee that we'll ever need, it looks like this:
case class Done[E, A](a: A, e: Input[E] = Input.Empty) extends Iteratee[E, A] {
 def fold[B](folder: Step[E, A] => Future[B]): Future[B] = folder(Step.Done(a, e))
This is the only done iteratee you'll ever need to indicate that you're done. In the Consume iteratee above, when we reached EOF, we created a done iteratee using an anonymous inner class, we didn't need to do this, we could have just used the Done iteratee above. The exact same thing holds for error iteratees:
case class Error[E](msg: String, e: Input[E]) extends Iteratee[E, Nothing] {
 def fold[B](folder: Step[E, Nothing] => Future[B]): Future[B] = folder(Step.Error(msg, e))
You may be surprised to find out the exact same thing applies to cont iteratees too - a cont iteratee just passes a function the folder, and that function, because the iteratee is immutable, is never going to change. So consequently, the following iteratee will usually be good enough for your requirements:
case class Cont[E, A](k: Input[E] => Iteratee[E, A]) extends Iteratee[E, A] {
 def fold[B](folder: Step[E, A] => Future[B]): Future[B] = folder(Step.Cont(k))
So let's rewrite our consume iteratee to use these helper classes:
def consume(data: Array[Byte]): Iteratee[Byte, Array[Byte]] = Cont {
 case Input.El(byte) => consume(data :+ byte)
 case Input.EOF => Done(data)
 case Input.Empty => consume(data)
A CSV parser
Now we're looking a lot simpler, our code is focussed on just handling the different types of input we could receive, and returning the correct result. So let's start writing some different iteratees. In fact, let's write an iteratee that parses a CSV file from a stream of characters. Our CSV parser will support optionally quoting fields, and escaping quotes with a double quote.
Our first step will be to write the building blocks of our parser. First up, we want to write something that skips some kinds of white space. So let's write a general purpose drop while iteratee:
def dropWhile(p: Char => Boolean): Iteratee[Char, Unit] = Cont {
 case in @ Input.El(char) if!p(char) => Done(Unit, in)
 case in @ Input.EOF => Done(Unit, in)
 case _ => dropWhile(p)
Since we're just dropping input, our result is actually Unit. We return Done if the predicate doesn't match the current char, or if we reach EOF, and otherwise, we return ourselves again. Note that when we are done, we include the input that was passed into us as the remaining data, because this is going to be needed to be consumed by the next iteratee. Using this iteratee we can now write an iteratee that drops white space:
def dropSpaces = dropWhile(c => c =='' || c == '\t' || c == '\r')
Next up, we're going to write a take while iteratee, it's going to be a mixture between our earlier consume iteratee, carrying state between each invocation, and the drop while iteratee:
def takeWhile(p: Char => Boolean, data: Seq[Char] = IndexedSeq[Char]()): Iteratee[Char, Seq[Char]] = Cont {
 case in @ Input.El(char) => if (p(char)) {
 takeWhile(p, data :+ char)
 } else {
 Done(data, in)
 case in @ Input.EOF => Done(data, in)
 case _ => takeWhile(p, data)
We also want to write a peek iteratee, that looks at what the next input is, without actually consuming it:
def peek: Iteratee[Char, Option[Char]] = Cont {
 case in @ Input.El(char) => Done(Some(char), in)
 case in @ Input.EOF => Done(None, in)
 case Input.Empty => peek
Note that our peek iteratee must return an option, since if it encounters EOF, it can't return anything.
And finally, we want a take one iteratee:
def takeOne: Iteratee[Char, Option[Char]] = Cont {
 case in @ Input.El(char) => Done(Some(char))
 case in @ Input.EOF => Done(None, in)
 case Input.Empty => takeOne
Using the take one iteratee, we'll build an expect iteratee, that mandates that a certain character must appear next otherwise it throws an error:
def expect(char: Char): Iteratee[Char, Unit] = takeOne.flatMap {
 case Some(c) if c == char => Done(Unit)
 case Some(c) => Error("Expected " + char + " but got " + c, Input.El(c))
 case None => Error("Premature end of input, expected: " + char, Input.EOF)
Notice the use of flatMap here. If you haven't come across it before, in the asynchronous world, flatMap basically means "and then". It applies a function to the result of the iteratee, and returns a new iteratee. In our case we're using it to convert the result to either a done iteratee, or an error iteratee, depending on whether the result is what we expected. flatMap is one of the fundamental mechanisms that we'll be using to compose our iteratees together.
Now with our building blocks, we are ready to start building our CSV parser. The first part of it that we'll write is an unquoted value parser. This is very simple, we just want to take all characters that aren't a comma or new line, with one catch. We want the result to be a String, not a Seq[Char] like takeWhile produces. Let's see how we do that:
def unquoted = takeWhile(c => c!= ',' && c!= '\n').map(v => v.mkString.trim)
As you can see, we've used the map function to transform the end result from a sequence of characters into a String. This is another key method on iteratees that you will find useful.
Our next task is to parse a quoted value. Let's start with an implementation that doesn't take into account escaped quotes. To parse a quoted value, we need to expect a quote, and then we need to take any value that is not a quote, and then we need to expect a quote. Notice that during that sentence I said "and then" 2 times? What method can we use to do an "and then"? That's right, the flatMap method that I talked about before. Let's see what our quoted value parser looks like:
def quoted = expect('"')
 .flatMap(_ => takeWhile(_!= '"'))
 .flatMap(value => expect('"')
 .map(_ => value.mkString))
So now you can probably start to see the usefulness of flatMap. In fact it is so useful, not just for iteratees, but many other things, that Scala has a special syntax for it, called for comprehensions. Let's rewrite the above iteratee using that:
def quoted = for {
 _ <- expect('"')
 value <- takeWhile(_!= '"')
 _ <- expect('"')
} yield value.mkString
Now at this point I hope you are getting excited. What

Correlation poses a serious threat to many engineered systems because the simultaneous failure of multiple components can dangerously degrade performance. Given the high cost of system failures in business and mission-critical applications, methods to explicitly consider the impact of correlation on system reliability are essential. This paper constructs a stochastic-flow network model to analyze the performance of a computer network, where there exists correlation between the failures of all the physical lines and routers comprising the edges and nodes of the network. That is, we address global-scale events that can cause widespread damage to the performance of the network. We propose a simulation approach to estimate the probability that a given amount of data can be sent from a source to sink through this network. This probability that the network satisfies a specified level of demand is referred to as the system reliability. Experimental results demonstrate that correlation can produce a substantial impact on system reliability. The proposed approach, thus, captures the influence of correlation on system reliability and offers a method to quantify the utility of reducing correlation.

Fact Sheet 514
Mycobacterium Avium Complex (MAC)
Mycobacterium Avium Complex (MAC) is a serious illness caused by common bacteria. MAC is also known as MAI (Mycobacterium Avium Intracellulare). MAC infection can be localized (limited to one part of your body) or disseminated (spread through your whole body, sometimes called DMAC). MAC infection often occurs in the lungs, intestines, bone marrow, liver, and spleen.
The bacteria that cause MAC are very common. They are found in water, soil, dust, and food. Almost everyone has them in their body. A healthy immune system will control MAC, but people with weakened immune systems can develop MAC disease.
Up to 50% of people with AIDS may develop MAC, especially if their CD4 cell count is below 50. MAC almost never causes disease in people with more than 100 CD4 cells.
The symptoms of MAC can include high fevers, chills, diarrhea, weight loss, stomach aches, fatigue, and anemia (low numbers of red blood cells). When MAC spreads in the body, it can cause blood infections, hepatitis, pneumonia, and other serious problems.
Many different opportunistic infections can cause these symptoms. Therefore, your health care provider will probably check your blood, urine, or saliva to look for the bacteria that causes MAC. The sample will be tested to see what bacteria are growing in it. This process, called culturing, can take several weeks. Even if you are infected with MAC, it can be hard to find the MAC bacteria.
If your CD4 cell count is less than 50, your health care provider might treat you for MAC, even without a definite diagnosis. This is because MAC infection is very common but can be difficult to diagnose.
The MAC bacteria can mutate and develop resistance to some of the drugs used to fight it. Health care providers use a combination of antibacterial drugs (antibiotics) to treat MAC. At least two drugs are used: usually azithromycin or clarithromycin plus up to three other drugs. MAC treatment must continue for life, or else the disease will return.
People react differently to anti-MAC drugs. You and your health care provider may have to try different combinations before you find one that works for you with the fewest side effects.
The most common MAC drugs and their side effects are:
- Amikacin (Amkin): kidney and ear problems; taken as an injection.
- Azithromycin (Zithromax, see fact sheet 530): nausea, headaches, vomiting, diarrhea; taken as capsules or intravenously.
- Ciprofloxacin (Cipro or Ciloxan, see fact sheet 531): nausea, vomiting, diarrhea; taken as tablets or intravenously.
- Clarithromycin (Biaxin, see fact sheet 532): nausea, headaches, vomiting, diarrhea; taken as capsules or intravenously. Note: The maximum dose is 500 milligrams twice a day.
- Ethambutol (Myambutol): nausea, vomiting, vision problems.
- Rifabutin (Mycobutin): rashes, nausea, anemia. Many drug interactions.
- Rifampin (Rifampicin, Rifadin, Rimactane): fever, chills, muscle or bone pain; can turn urine, sweat, and saliva red-orange (may stain contact lenses); can interfere with birth control pills. Many drug interactions.
The bacteria that cause MAC are very common. It is not possible to avoid being exposed. The best way to prevent MAC is to take strong antiretroviral medications (ARVs). Even if your CD4 cell count drops very low, there are drugs that can stop MAC disease from developing in up to 50% of people.
The antibiotic drugs azithromycin, rifabutin, and clarithromycin have been used to prevent MAC. These drugs are usually prescribed for people with less than 50 CD4 cells.
Combination antiretroviral therapy can make your CD4 cell count go up. If it goes over 100 and stays there for 3 months, it may be safe to stop taking medications to prevent MAC. Be sure to talk with your health care provider before you stop taking any of your prescribed medications.
Several drugs used to treat MAC interact with many other drugs, including ARVs, antifungal drugs, and birth control pills. This is especially true for rifampin, rifabutin, and rifapentine. Be sure your health care provider knows about all the medications that you are taking so that all possible interactions can be considered.
MAC is a serious disease caused by common bacteria. MAC can cause serious weight loss, diarrhea, and other symptoms.
If you develop MAC, you will probably be treated with azithromycin or clarithromycin plus one to three other antibiotics. You will have to continue taking these drugs for life to avoid a recurrence of MAC.
People with 50 CD4 cells or less should talk with their health care providers about taking drugs to prevent MAC.

Support Center
We've put together some commonly asked questions to give you more information about the services and products we offer.
Don't see what you need?
B and U Packaging Codes
Why are "B" and "U" packaging codes no longer required?
To simplify the Coilcraft part numbering (ordering code) system, the use of the "B" and "U" packaging codes (B = Less than full reel, U = Less than full reel) is no longer needed. When ordering, use the standard/default packaging code as shown on the data sheet. This update applies to all Coilcraft part numbers.
Is the product changing?
No. The only change is to the packaging code.
Does this change affect form, fit or function?
Has this product been designated as EOL?
Has the part number changed?
No. The only change is to the packaging code.
Is the part obsolete?
Cleaning / Washing
What cleaning solutions can be used on Coilcraft's parts?
Core and winding losses
Yes, core and winding loss data for many of our power inductors is included in our online core loss calculator.
A detailed discussion of core and winding losses is provided in Choosing Inductors for Energy Efficient Power Applications.
Date code / Lot code
How do I interpret the codes on the label of the reel of parts I received?
Coilcraft reel labels contain a manufacturing date code embedded in the first six characters of the "LOT CODE" field.
The date is in MMDDYY format. In the example below, the code 101314 = October 13, 2014.
Dash numbers
What is a dash number?
A dash number is typically a three-digit code that corresponds to the three numbers that follow the dash in a part number. This code refers to the value in nanoHenries, where the first two digits are the value and the last digit is the multiplier (10^x) or number of zeroes that follow.
Therefore, 103 would be 10 × 10^3 (or 10 followed by three zeroes), which equals 10,000 nH, equivalent to 10 µH.
Other examples:
 - -394 = 39 × 10^4 = 390000 = 390,000 nH = 390 µH
 - -102 = 10 × 10^2 = 1000 = 1000 nH = 1.0 µH
 - -501 = 50 × 10^1 = 500 = 500 nH = 0.5 µH
Discontinued / Obsolescence / EOL / PCN / PDN
Some of your parts are marked "Discontinued."
While Coilcraft has discontinued a small number of series, we will, when feasible, continue to support existing customers with previous order history for this series. For many of these parts, we have developed a newer series that surpasses the performance of the discontinued part. If you search for the discontinued part on our site, you will be guided to the replacement part.
Coilcraft can notify your company when products that you purchase are changed (Product Change Notice) or discontinued (Product Discontinuation Notice). Sign up for PCN and PDN emails at _URL_
A number of your parts are designated as "Not recommended for new designs." Does this mean that I won't be able to buy these parts again?
For these series, we will continue to support existing customers with previous order history of the NRND part.
We used to buy 20% tolerance chip inductors from Coilcraft. Why are they no longer available?
Manufacturing processes have consistently improved, and all of our ceramic chip inductors now fall into the 5% or better tolerance range. These parts are an improvement of the parts you used to buy.
ESD (Electrostatic discharge)
Do you perform ESD testing on your components?
Coilcraft performs ESD testing per AEC-Q200 standards on all of our AEC-qualified products.
Export Control Classification Number (ECCN)
Where can I find the ECCN for your parts?
Coilcraft components are subject to the Export Administration Regulations (EAR), but the parts are not listed with a specific Export Control Classification Number (ECCN) on the Commerce Control List (CCL). EAR99 items generally consist of low-technology consumer goods and do not require a license in many situations. However, if the proposed export of an EAR99 item is to an embargoed country, or to an end-user of concern or in support of a prohibited end-use, a license may be required.
Effects of Ground Plane or Substrate
How can I predict the changes in inductance, Q and SRF when mounting your RF inductors over a ground plane or on various substrates?
Modelithics has measured many Coilcraft RF inductor series with a variety of substrate types and thicknesses. They have created global models that scale the substrate-sensitive parasitics for accurate simulations. View their models at: _URL_
The effects of ground plane proximity depend on inductor geometry and test frequency, along with substrate thickness and dielectric constant. In many cases, the effect is small, but it can be significant in very tight-tolerance applications. The interaction of the magnetic field of an inductor with a metal ground plane is a complicated 3D E/M problem that requires careful measurement or simulation under specific application conditions. For this reason, Coilcraft cannot quantify these effects in general.
Inductance of transformer secondaries
We do not provide a specification for transformer secondary inductance. However, you can calculate it as primary inductance times the square of the turns ratio. For example, for a 2:1 transformer with a primary inductance of 10 µH, the inductance of the secondary is 10 µH × (0.5)^2 = 2.5 µH.
Junction temperature
Theta JA, Theta JC, Rja and Rjb are terms applicable only to active devices, such as integrated circuits. Inductors and transformers do not contain semiconductor material junctions and, so, do not have the same potential failure modes. Theta JA and Theta JC are therefore not applicable to inductors and transformers. See below for a discussion of thermal resistance.
Lead free / RoHS
Are all Coilcraft parts lead free?
Please read Coilcraft RoHS policy.
Medical, military and aerospace qualified
Coilcraft's Critical Products and Services Group offers products designed and tested specifically for these applications. Address your needs in an email to [email protected], or fax quote requests to _PHONE_.
Moisture Sensitivity Level (MSL)
What is the Moisture Sensitivity Level of Coilcraft parts?
All Coilcraft components have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited floor life at <30°C / 85% relative humidity. To be classified MSL Level 1, the component must pass the JEDEC J-STD-020 criteria of 168 hours in a chamber with 85°C / 85% relative humidity.
That type of noise is usually due to a mechanical resonance in the component that is excited by the electrical conditions of the circuit, known as magnetostriction, and does not indicate a defect in the part. It is very dependent on the application conditions and is not always possible to eliminate by changes to the inductor alone.
Changing the switching frequency is often the best way to eliminate the noise. Applying a dampening material (electronic-grade encapsulant, potting compound, etc.) may decrease the sound level produced, or the increased mass of a larger component may dampen or shift the resonance to a different frequency.
Non-magnetic products
All of our air-core inductors are non-magnetic: Air-core Inductors
All of our all-ceramic core RF chip inductors are non-magnetic, with the exception of those with tin over nickel terminations.
Non-magnetic ceramic series include CS, DS, HP, HQ, PA, HC, CT, HS, and HT: All-Ceramic Chip Inductors
Are there any outgassing issues with Coilcraft inductors?
There can be outgassing from any material under the right conditions. However, as a general rule, outgassing has not been reported with Coilcraft parts in commercial applications, and testing has not been required. For specialized applications where outgassing is a particular concern, we recommend you contact our Critical Products group for products that have passed NASA low outgassing specifications.
Part marking / Color codes
I received parts with dot markings on them. Do the dots have a specific meaning?
Your power inductors have numbers and letters on them. What is the "dash number" you refer to on your dimensional drawings? What do these numbers mean?
Part identification is specific to each product series. Refer to the part's data sheet for specific part identification markings. For very small parts, a marking may not be used; traceability to the original packaging information is required for accurate identification.
Power inductors, except for our smallest series, are commonly marked with a three-digit code that corresponds to the three numbers that follow the dash in the part number. This code refers to the value in nanoHenries, where the first two digits are the

Is Hosea a minor prophet?
The Twelve, also called The Twelve Prophets, orThe Minor Prophets, book of the Hebrew Bible that contains the books of 12 minor prophets: Hosea, Joel, Amos, Obadiah, Jonah, Micah, Nahum, Habakkuk, Zephaniah, Haggai, Zechariah, and Malachi.
Why did Athaliah kill the royal family?
When Athaliah hears of her son Ahaziah's death by Jehu, according to the accounts in 2 Kings and 2 Chronicles, she destroys the entire royal family. The rabbis add that these violent deaths serve as punishment for David's having kept himself in safety while his army fought against Absalom (Ginzberg, 1968:6, 268).
Where did the term Jezebel come from?
Jezebel was the daughter of the priest-king Ethbaal, ruler of the coastal Phoenician cities (now in Lebanon) of Tyre and Sidon (Arabic: Ṣaydā). When Jezebel married Ahab (ruled c. 874–c. 853 bce), she persuaded him to introduce the worship of the Tyrian god Baal-Melkart, a nature god.
Who was Baal?
Baal, god worshipped in many ancient Middle Eastern communities, especially among the Canaanites, who apparently considered him a fertility deity and one of the most important gods in the pantheon. As such, Baal designated the universal god of fertility, and in that capacity his title was Prince, Lord of the Earth.
What does the name Shirley mean?
Shirley is a given name and a surname originating from the English place-name Shirley, which is derived from the Old English elements scire ("shire") or scīr ("bright, clear") and lēah ("wood, clearing, meadow, enclosure").
What did Jezebel say to Elijah?
So Jezebel sent a messenger to Elijah to say, "May the gods deal with me, be it ever so severely, if by this time tomorrow I do not make your life like that of one of them." while he himself went a day's journey into the desert. He came to a broom tree, sat down under it and prayed that he might die.
Was Samaria a part of Israel?
According to the Hebrew Bible, the Israelites captured the region known as Samaria from the Canaanites and assigned it to the Tribe of Joseph. After the death of King Solomon (c. 931 BC), the northern tribes, including those of Samaria, separated from the southern tribes and established the separate Kingdom of Israel.
Where is Armageddon located?
Author of The Heresy of the Free Spirit and The Powers of Prophecy: the Cedar of Lebanon Vision from the Armageddon, (probably Hebrew: "Hill of Megiddo"), in the New Testament, place where the kings of the earth under demonic leadership will wage war on the forces of God at the end of history.
Is Caesarea Philippi in Israel?
It was adjacent to a spring, grotto, and related shrines dedicated to the Greek god Pan. Now nearly uninhabited, Caesarea is an archaeological site in the Golan Heights.

How Do You Like Them Rectangles?
Welcome to The Riddler. Every week, I offer up problems related to the things we hold dear around here: math, logic and probability. There are two types: Riddler Express for those of you who want something bite-size and Riddler Classic for those of you in the slow-puzzle movement. Submit a correct answer for either,1 and you may get a shoutout in next week's column. If you need a hint, or if you have a favorite puzzle collecting dust in your attic, find me on Twitter.
This week, we've got two puzzles from the forthcoming puzzle book "The Original Area Mazes," by Alex Bellos, Naoki Inaba and Ryoichi Murakami. The goal of these puzzles, which are also known by the Japanese term "menseki meiro," is to figure out what the "?" equals. The only math you'll need to know is that length times width equals area. Keep in mind that the diagrams aren't necessarily to scale — this is about logic, not measuring.

Solution to last week's Riddler Express
Congratulations to 👏 Kristian Hougaard 👏 of Copenhagen, Denmark, winner of last week's Express puzzle!
Twenty ghostbusters are on their annual camping retreat. Two of them, Abe and Betty, have discovered that another pair, Candace and Dan, are in fact ghosts posing as ghostbusters. Abe and Betty hatch a plan: When all 20 campers are sitting in a circle around the campfire, Abe will fire his proton pack at Candace, and Betty will simultaneously fire her proton pack at Dan, annihilating the ghosts. However, if two proton streams cross, it means the end of all life on Earth. If the ghostbusters are arranged randomly around the fire, what are the chances that Abe and Betty will cross the streams?
The chances are 1/3.
There are 20 ghostbusters, but we only really care about four of them — Abe, Betty, Candace and Dan. The position of the other 16 won't affect the possible crossing of the streams, so let's ignore them. (Sorry, you 16 irrelevant ghostbusters.)
Fix Abe's spot at the campfire — say he's on the north side. There are then three places his co-ghostbuster Betty can sit — east, west or south. The ghosts, Candace and Dan, will sit in the other two seats. There are 3*2*1 or six possibilities for the seating in the east, west and south seats. In exactly two of these arrangements — the two where Candace occupies the southern seat, forcing Abe to fire across the circle — the ghostbusters will cross their proton streams. Each of these six arrangements is equally likely, so the chances of stream-crossing disaster are 2/6 = 1/3.

Congratulations to 👏 Carl Ober 👏 of New Britain, Connecticut, winner of last week's Classic puzzle!
Last week, you faced four sticky questions:
 1. If you break a stick in two places at random, forming three pieces, what is the probability of being able to form a triangle with the pieces?
 2. If you select three sticks, each of random length (between 0 and 1), what is the probability of being able to form a triangle with them?
 3. If you break a stick in two places at random, what is the probability of being able to form an acute triangle — where each angle is less than 90 degrees — with the pieces?
 4. If you select three sticks, each of random length (between 0 and 1), what is the probability of being able to form an acute triangle with the sticks?
The probabilities are, respectively, 1/4, 1/2, \ln(8)-2 and 1-\pi/4.
To solve these geometry problems, let's draw some pictures! We'll take the questions one by one.
For No. 1: Call the lengths of the three pieces x, y and z. They form a triangle if the sum of any two sides are larger than the third side (x+y>z, y+z>x and x+z>y). This is called the triangle inequality!
Now to our stick, which we'll assume is one unit long. Call the points where we broke it a and b, both chosen at random. That gives us pieces of length a, b minus a and 1 minus b. Substituting those lengths in for x, y and z above simplifies those triangle equalities:
 - x+y>z \Rightarrow a+(b-a)>1-b \Rightarrow b>1-b \Rightarrow 2b>1 \Rightarrow b>1/2
 - y+z>x \Rightarrow (b-a)+(1-b)>a \Rightarrow 1-a>a \Rightarrow a<1/2
 - x+z>y \Rightarrow a+(1-b)>b-a \Rightarrow 2a+1 > 2b \Rightarrow b-a<1/2
So, armed with the lengths of those three pieces, we can visualize the answer to the problem. As long as our randomly selected points on the stick (a and b) satisfy those inequalities we just made, we know we can make a triangle. We can plot values of (a,b) as coordinates in a plane, as Laurent Lessard did:
The shaded areas are where the inequalities are satisfied. (There are two triangles because one corresponds to when a>b and the other when b>a.) Those areas take up ¼ of the total square, which gives us our answer: 25 percent.
For No. 2: What if, instead of pieces from one stick, we pick up three sticks of random length somewhere between zero and one? This is a little trickier. When we plotted the first problem, it could be collapsed to two dimensions, because we were only really worried about two sticks — the length of our third piece was automatically determined by the length of our first two pieces. But this problem is in three dimensions, so the solution needs to be plotted not in a one-by-one square but rather in a one-by-one-by-one cube.
To help solve the problem, consider what wouldn't solve it: a violation of our triangle inequalities. Suppose, for example, that x>y+z, which makes it impossible to build a triangle. In that formulation, those points are contained in a pyramid bounded by the planes y=0, z=0, x=1 and x=y+z. There are three such pyramids in this cube, one for each of the ways the triangle inequality can be violated.
Each of those pyramids has a volume of ⅙. (A pyramid has a volume equal to the area of its base times its height, all divided by three. Our pyramid in question has height 1 and a triangular base with area ½.). Therefore, there is a ½ chance we can't make a triangle, and a ½ chance we can. And so we have the answer to the second problem.
No. 3: Getting tougher still (as though that were possible)! Now it's time for calculus. Guy D. Moore explains this one for us:
The problem asks us to ensure that three pieces form an acute triangle. Consider three pieces with lengths x>y>z.
First, think about a right triangle. The formula for that, as our middle school teachers drilled into our heads, is x^2=y^2+z^2. (Otherwise known as the Pythagorean Theorem.) To have an acute triangle, all angles must be less than 90 degrees, so we tweak that formula: x^2<y^2+z^2.
From this we get that y<x and (1-x)^2<y^2+(x-y)^2, which is the same as
\begin{equation*}x<\frac{1-2y^2}{2(1-y)}\end{equation*}
Since we're dealing with pieces of the same stick and not three separate sticks, we can return to plotting in two dimensions, not three. And our mirrored-triangle plot is useful again since our answer lies within those two original triangles. This time, though, we need to draw two new three-pointed shapes within those two triangles. The area of those shapes will be our answer — the probability of an acute triangle.
So to calculate our new shapes, we need to cut pieces out of our original triangles. The area of one of those pieces is expressed in an integral (which is the calculus part of the solution). That integral is:
\begin{equation*}\int_0^{1/2}\frac{1-2y}{2-2y}dy=\frac{1-\ln(2)}{2}\end{equation*}
There are six shapes, each with the same area, cut out of our one-by-one square, leaving:
\begin{equation*}1-3(1-\ln(2))=\ln(8)-2\end{equation*}
In that equation, "ln"

The following is an observation of Washington farm and trade policy made by DTN's "well-placed observer."
Last year, Sen. Richard Burr, R-N.C., introduced legislation that would combine the Department of Energy and the Environmental Protection Agency. This week, Rep. Marsha Blackburn, R-Tenn., is expected to introduce a similar proposal in the House. No Senate committee has yet to hold a hearing on Burr's bill, which was introduced last May.
According to Blackburn, the proposal to create a Department of Energy and the Environment would save an estimated $3 billion in the next year.
In a statement, Blackburn also said, "If we are going to put America back on the right path to prosperity, we need to cut the fat in Washington and get rid of excessive regulations that are stifling the ability of our nation's small businesses to grow and create jobs." Her statement did not indicate how combining the two government organizations would reduce the number of regulations that each would have issued if they had remained separate.
Burr's proposal would require the secretary of the new department to issue a determination of whether each proposed rule would or would not have a "substantial impact on the economy of the United States or large numbers of individuals or businesses." It does not quantify what would constitute a "substantial impact," meaning that that issuance of regulations could be held up by court actions convened to define the ambiguous term.

Thus, p1=p2 implies pb=pc and vice versa. The hypothesis of interest in Equation (2) involving p1 and p2 can be expressed in terms of pb and pc :
H0:pb=pc,vs.Ha:pbpc.
McNemar's test evaluates the difference between the concordant and discordant pairs, b and c, that is,
zm=|bc|1b+c.
A large difference leads to rejection of the null. By normalising this difference, the statistic zm above follows approximately the standard normal for large sample size.
Paired count outcomes
For count outcomes, McNemar's test clearly does not apply. The paired t-test is also inappropriate for such outcomes. First, the difference di=yi2yi1 does not follow a normal distribution. Second, even if both yi1 and yi2 follow a Poisson distribution, the difference di is not a Poisson variable; di in general is not even guaranteed to have non-negative values.
One approach that has been used to compare paired count outcomes is the Wilcoxon signed-rank test. Within our context, let Ri denote the rank of di based on its absolute value |di| . The ranks are integers that indicate the position of |di| after rearranging them in ascending order.1 The signed-rank test has the following statistic:
Wilcoxon signed rank test:Wn+=i=1nI{di>0}Ri,
where I{di>0} denotes an indicator with the value 1 (0) if the logic di >0 is true (otherwise). Thus, Wn+ only adds up the ranks for the positive di 's.
The statistic Wn+ ranges from 0 to n(n+1)2 . Under H0 , about one-half of the di 's are positive. Thus, any pair ( di , dj ) has 50% chance that di+dj>0 . In terms of ranks, this means that the sum of Ri for positive di is about half of the range n(n+1)2 . Thus, we can specify the null as:
H0:θ=12,vs.H0:θ12,
where θ=Pr(di+dj>0) . Under the null H0 , Wn+ has mean n(n+1)4 , half of the range n(n+1)2 . The normalised Wn+ :
Un=(n2)1Wn+
has approximately a normal distribution with mean 12 and SE 13n for large samples, which is readily applied to calculate p values and/or confidence bands.
Since paired outcomes are a special case of general longitudinal outcomes, longitudinal methods can be applied to test the null. For example, both the generalised linear mixed-effects model (GLMM) and generalised estimating equations (GEE), two most popular longitudinal models, can be specialised to the current setting. When applying GLMM, we specify the following model:
yi1Poisson(μ1),yi2Poisson(μ2),log(μ1)=β0+z,log(μ2)=β0+β1+z,zN(0,σ2),
where z denotes a random effect to account for correlation between the paired outcomes, Poisson(μ) denotes a Poisson distribution with mean μ , exp() denotes the exponential and log() denotes the log function. The null of same mean between y1 and y2 can be expressed as:
H0:β1=0,vs.H0:β10.
Note that since the random effect z may be positive or negative and the random of the normal distribution is unbounded, the log transformation of the Poisson mean in Equation (4) is necessary to ensure that μ1 and μ2 stay positive.
For applying GEE, we only need to specify the mean of each paired outcome. This is because unlike GLMM, GEE is a 'semi-parametric' model and imposes no mathematical distribution on the outcomes. Thus, under GEE, both the Poisson distribution for each outcome and the random effect z for linking the paired outcomes are removed. The corresponding GEE is given by:
log[E(yi1)]=β0,log[E(yi2)]=β0+β1,1in.
Since there is no random effect in Equation (5), the log transformation is also not necessary and thus the GEE can be specified simply as:
E(yi1)=γ0,E(yi2)=γ0+γ1,1in.
Compared with the GLMM in Equation (4), the GEE above imposes no mathematical distribution either jointly or marginally, allowing for valid inference for a broad class of data distributions. The GLMM in Equation (4) may yield biased inference if: (1) at least one of the outcomes does not follow the Poisson; (2) the random effect z follows a non-normal distribution; and (3) y1 and y2 are not correlated according to the specified random-effect structure. In contrast, the GEE in Equation (5) forgoes all such constraints and yields valid inference regardless of the marginal distribution and correlation structure of the outcomes y1 and y2 .
Simulation study
In this section, we evaluate and compare the performances of the different methods discussed above by simulation. All simulations are performed with a Monte Carlo (MC) sample of M=2000 under a significance level of α=0.05 . Performance of a test is characterised by: (1) bias and (2) power. We consider both aspects when comparing the different methods.
Bias
If a test performs correctly, it should yield type I error rates at the specified nominal level α=0.05 . Several factors can affect the performance of the test. First, if data do not follow the assumed mathematical distributions, the test in general is biased. For example, if the paired t-test is applied to paired outcomes that are not bivariate normal, it will generally be biased. Second, with the exception of the paired t-test, all tests discussed above rely on large samples to provide valid results. When applied to small or moderate samples, such tests may have bias. For example, the normal distribution may not provide a good approximation to the sampling distribution of the statistic Un of the Wilcoxon signed-rank test Wn+ when applied to a sample size of, say, n=20 . Thus, to compare the performance of each different method, we consider sample sizes ranging from n= 10 to 200.
To evaluate the effects of model assumptions on test performance, we simulate correlated count responses yi1 and yi2 using a copula approach,2 where each outcome marginally follows a negative binomial (NB) distribution:
yi1NB(μ1,τ),yi2NB(μ2,τ),μ1=exp(β0+z),μ2=exp(β0+β1+z).
The above model deviates from the GLMM in Equation (4) in two ways. First, yi1 ( yi2 ) follows an NB, rather a Poisson. Second, correlation between yi1 and yi2 does not follow the normal distribution based on random effect. Unlike Poisson, NB has an extra parameter τ controlling for dispersion (variability). Thus, although Poisson and NB have the same mean, NB has a different (larger) variance than Poisson.1 Since NB(μ,τ) converges to Poisson(μ) as τ increases, selecting a relatively small τ allows us to examine the impact of the Poisson assumption on inference when the GLMM in Equation (4) is applied to count outcomes that are not compliant with the Poisson model.
For the simulation study, we set μ1=μ2=5,τ=1 and 5, and correlation between yi1 and yi2 to 0.5. To evaluate bias using MC simulation, we simulate paired outcomes yi1 and yi1 from the model in Equation (7), apply each of the tests discussed in the third section and compute p values for testing the null hypothesis. This process is repeated M=2000 times. A test has little or no bias if the proportion of nulls rejected over the M=2000 times is close to the nominal value α=0.05 .
Shown in table 2 are averaged p values for the different tests from their applications to the M=2000 simulated paired outcomes, where GLMM (Poisson) denotes the GLMM for Poisson in Equation (4), GLMM (NB) denotes the GLMM for NB distribution (by replacing the Poisson in the GLMM in Equation (4) with NB), GEE denotes the GEE without log transformation in Equation (6) and GEE (log-link) denotes the GEE with log transformation in Equation (5). For moderate to large sample sizes, n=100, 200, all tests yielded p values close to the nominal α=0.05 , except for GLMM (Poisson), which had highly inflated type I errors for τ=1 . As indicated earlier, with a small dispersion parameter such as τ=1 , NB has much more variability than its Poisson counterpart, leading to poor fit when fitting simulated data with the GLMM assuming the Poisson. Thus, the high bias in the type I error reflects model mis specification.

Defect detection of riveted lap joints using fiber laser acoustic emission sensors: This figure shows the initiation and growth of cracks between rivets in the upper left lap joint. The fiber laser sensor is mounted on the detection structure and measures the acoustic emission signal generated by the crack defect. The software records it as an acoustic event (AE event).
â€œWe have researched an on-site structural health monitoring (SHM) automation system that can effectively monitor key structural parameters such as temperature, internal stress, impact, and crack defects; and can reliably ensure that structural damage conditions reach a critical level It was detected to increase structural safety and speed of information feedback while reducing operational costs for the naval platform,â€ said Dr. Geoffrey Cranch, a physicist from the Department of Optical Sciences. â€œAt present, there is no U.S. service that uses in-situ technology to manage it. Equipment structure health." To achieve this goal, the most critical is the need for a sensor that can detect near-real-time acoustic emission signals associated with the appearance and growth of defects such as cracks. Moreover, these sensors must be smaller, lighter, easier to handle, and have comparable or increased sensitivity than most existing electronics. The ultimate goal is to make these components have a small system footprint and high reliability.
Part of the research funding provided by the Department of Materials Science of the US Naval Research Office (ONR), NRL is developing a laser sensor whose width is about the width of a human hair filament. During the test, the researchers installed a distributed feedback fiber laser acoustic emission sensor in a set of aluminum rivets and measured a 0.5 MHz bandwidth acoustic emission signal generated in a two-hour accelerated fatigue test. An equivalent electrical sensor measures.
This embedded sensor can be used to resolve the periodic â€œfrettingâ€ acoustic events of the rivets and to detect acoustic emission information from cracks. Time-lapse imaging of the lap will allow the observed fracture to be correlated with the measured signal.
In addition to crack detection, this fiber laser sensor can also effectively detect impact damage effects. In addition, the sensor has the potential to integrate with existing fiber strain and temperature sensing systems. This provides a multi-parameter sensing capability to meet the operational safety requirements of the field structure health monitoring system. It is worth mentioning that this will also significantly reduce the overall cost.
"Our research team has demonstrated the ability of this fiber laser sensing technology to detect crack-generated ultrasonic acoustic emission signals in a simulated fatigue environment," said Cranc. "The novelty of this research is mainly fiber laser transmission. Sense technology and its application methods etc."
Acoustic signals generated from flaws such as cracks can also be measured using piezoelectric sensors, and this technique also facilitates existing fault prediction work. However, piezoelectric sensing technology is not very practical in many aspects due to its large device size and limited distributed monitoring capabilities.
It is emphasized that this technology will likely be applied in many areas other than the military field. "Our research and application focus is on defenses such as the Navy, such as aircraft, ships, and submarines. If some bridges or building structures contain critical components that are vulnerable to fatigue and failure, then this technology can also be applied to these. Continuous monitoring of the structure."
At present, no other intrinsic optical fiber sensor can match the performance achieved by the fiber laser acoustic emission sensor in the laboratory. Compared with some existing electrical sensing technologies, fiber laser sensors have been shown to have comparable or even higher acoustic emission signal sensitivity. The system has been able to integrate multiple fiber laser sensors into a bundle of fibers. At present, the work of the research team is mainly to understand and explain these acoustic emission data to calculate some useful index parameters (such as failure probability, etc.). The direction of future improvement is mainly focused on the realization of phased array beamforming technology to effectively determine the specific location of cracks and other defects.

Emule 0.50A Process Response Packet Failed
Posted 09 June 2011 - 12:07 PM
hello, we are doing some research work in eMule-kad and have recorded all the packets including incoming and outcoming packets in a official eMule 0.50a client. In our log we find an interesting phenomenon where a specific contact use another udp port to reply our client's request(for example KADEMLIA2_REQ). So in function CSearch::ProcessResponse(…), we cant find the corresponding contact that we have made a request to, and cant process this KADEMLIA2_RES packet correctly. We have investigated some network configure conditions, for example Cone NAT and Symmetric NAT. But these trial don't make any sense and we cant explain it. Finally we just consider it is probable that there are two NAT device in the specific contact's network environment，one for incoming packet and another for outcoming packet. As a countermeasure, for a specific response we firstly judge it by its ip and udp port, if failed, we only use ip. We have confirmed that there are scarcely two contacts having the same ip in a Search object.

FALCON – IFE's Flow Assurance Loop for CO2 transport.
The test facility contributes with research for safe and cost effective CO2 transport through experimental results used for modelling and validation of pipeline simulators.
The CO2 flow loop is a semi-outdoor test rig designed and built to accommodate test campaigns related to pipeline transport and well injection of pure CO2 or CO2 mixtures. The design and the instrumentation of the test facility serves the main motivation for building the flow loop, emphasizing pipeline flow of CO2 with phase transitions.
The FALCON test facility has a typical multiphase flow, closed loop design, as illustrated in below (Figure 2). It consists of a test section (5), a return section, a main separator (1), a liquid pump (2), a gas booster (3) and various auxiliary components. It also has a unique system for pressurization, consisting of a high-pressure cylinder (6) with a piston operated by a hydraulic aggregate.
For tests involving depressurization, flush-out and choking tests, for example, the loop is reconfigured as a once-through setup, normally using the storage tank (7) as a low-pressure reservoir/sink and the high-pressure cylinder with moveable piston as a mass flow source.
The flow rig has an advanced, combined heating and cooling system and is well insulated.
Operational control of the loop is through a fully integrated computer system, which also handles the data acquisition.
The test section can be inclined at any upward or downward inclination from horizontal to vertical.
Schematic of the FALCON test facility with the key components. 1: Main separator, 0.5 m3, 2: Liquid pump, 3: Gas booster, 4: Flow meters, 5: Test section (ID = 44 mm), 6: High-pressure cylinder with piston, 0.08 m3, 7: Storage tank, 1.2 m3, 8: Compressor.
Topics that can be studied include:
- Basic steady state multiphase flow of CO2, measuring pressure drop, holdup and flow regimes in pipelines with inclinations form horizontal to vertical
- Flow through wellhead chokes with significant pressure drop, Joule-Thomson cooling and phase transition
- Various shut-in and startup scenarios with heat transfer and phase transition
- Pipeline and vessel depressurization for pipeline integrity during maintenance operations and unintended pipeline rupture
- Pressure transients caused by sudden valve closing; fluid hammering
The test facility can also be used for testing instruments and components.

The test facility is currently equipped with instruments for control of input parameters (flow rates, pressure and temperature) and for characterization of the flow and other phenomena in the test section. In addition to the many pressure and temperature sensors, these include:
- Flow rate meters (Coriolis and ultrasonic meters)
- Density meters
- Differential pressure transducers for pressure drop measurements
- Fast response pressure sensors
- Accelerometer and Acoustic Emission sensor for cavitation/vibration monitoring
- Two broad beam gamma-densitometers for phase fraction/holdup measurements

|MadSci Network: Development|
Hi Becky, That is a very interesting question and at first it doesn't seem to make sense that the answer could be yes. But the answer is yes, children have more bones than adults. Why is that? If you have a baby brother or sister, or if you have friends who have baby brothers or sisters (about 1 or 2 years old)you may have been told not to push on the "soft spot" on the baby's head. If you try to find that "soft spot" on your head or your friends' heads, it is not there. You see, as babies get older, that "soft spot" disappears. There is no magic about it, what happens is that as bones of the skull develop they start out as several bony segments and eventually fuse into a single bone. So, while the top of the skull in the adult is composed of 4 bones, in a new born there may be as many as 8 separate bone segments (depending on the age of the baby and the manner in which those bones develop). Another way that kids have more bones than adults is due to a cartilage known as the "epiphyseal plate." This is also known as the "growth plate" and every long bone, such as the humerus (the bone of the arm) has an epiphyseal plate at each end. The rounded parts of the long bone than are separated from the long part (shaft or diaphysis) of the long bone. So in an adult the humerus is a single bone, composed of a shaft (diaphysis) and two heads (epiphyses), all fused into a single bone. However, in a growing child the humerus is composed of three distinct, separate bones, the diaphysis and the two epiphyses. So the adult has a right and a left humerus (= 2 bones) whereas the child has two epiphyses and a diaphysis on the right side and two epiphyses and a diaphysis on the left side (=6 bones). But when the child stops growing, the epiphyses will fuse with the diaphysis and then that child will also have 2 bones rather than six. I hope you don't mind that the answer is so long, but it is the story of a long bone, isn't it? Good luck in school. Leslie Gartner Anatomy, OCBS Dental School University of Maryland Baltimore, MD

Studies of the distribution of mating success among males in frog choruses typically seek to identify specific phenotypic attributes that confer a higher mating success on certain individual males. These attributes invariably relate to competition among males: either direct competition in the form of aggression, or competition to attract and be chosen by females. In this paper, we present evidence that an additional factor may operate in frog choruses. We show that individual males who mate on a given night enjoy a higher probability of being successful on the next night, and we suggest that this is because successful mating enables males to conserve energy.

Where is Linux kernel stored? Where is the Linux Kernel located? Since the Linux kernel is a piece of code, it must be stored somewhere on the file-system, such that every time the system reboots, the kernel is loaded in the memory. In Debian/Ubuntu systems, the Linux kernel can be found within the /boot directory.
Where is the kernel located? Kernel: As we can see, it's right in the middle of the layers. It's the core of the OS. Hardware: It's the physical machine, the base of the system. It consists of memory, the processor or the central processing unit (CPU), and input/output (I/O) components such as graphics, storage, and networking.
Where is the kernel located in RAM? The details are architecture-dependent but the kernel resides at a memory range at the top of the address space by convention.
What is kernel memory in Linux? pages. The kernel has full access to the system's memory and allows processes to safely access this memory as they require it. Often the first step in doing this is virtual addressing, usually achieved by paging and/or segmentation.
