The Warsaw Metro is one of Europe's youngest underground/subway systems. Not suprisingly it consists of only one line, which is still under construction. Plans to build an underground in the city date back to 1925 when the first plans of such a system were drawn up. World War II, however, brought an end to the ambitious undertaking, putting it to a halt for nearly fourty years (a brief and half-hearted attempt in the 1950s can be disregarded here).
Finally, in 1984 (sic!) the program was given a green light by the Communist government and the first tunnels were built. Lack of funds, poor planning, and tedious bureaucracy meant that the works went on very slowly. The Metro was launched in 1995 with a total of 11 stations. Since then, however, the project has speeded up substantially; the line now has 14 stations along a distance of approximately 15 kilometres, and is to be completed with a total of 19 stations by 2005. A second line, crossing the city from East to West is to be completed by 2010.
The stations of the first line are (South to North):

Lake Weatherford (Trinity River Basin)
Lake Weatherford is located seven miles east of Weatherford in Parker County, on the Clear Fork Trinity River, a tributary of the Trinity River. Lake Weatherford is owned and operated by the City of Weatherford and serves primarily as a water supply source for municipal and industrial uses. Construction on Weatherford Dam began in June of 1956, with deliberate impoundment and completion of the dam occurring in March of 1957.
In 1993 the service spillway was modified to repair flood damages and increase the overall spillway capacity. The dam crest was raised 3 feet to an elevation of 917.0 feet above mean sea level. A new service spillway inlet consisting of a four-fingered radial labyrinth crest was constructed and connected to the existing 9-foot square discharge conduit. The crest of this service spillway is at an elevation of 896 feet above mean sea level. The second stage emergency spillway channel at an elevation of 906 feet was widened to a total length of 1,400 feet. According to TWDB 2008 survey, at the top of conservation pool elevation, 896 feet above mean sea level, the lake has a surface area of 1,112 acres and contains 17,812 acre-feet of water. This reservoir controls a drainage area of about 109 square miles.

Clarkdale AZ (July 9, 2019) – The Northern Arizona Audubon Society is pleased to announce that it has partnered with the Greenwood Fund and Yavapai College to provide a non-credit course on the natural history of the Verde Valley. The Greenwood Fund was started in memory of Dena Greenwood, a well-known and beloved member of the local community.
A longtime resident of the Verde Valley who passed away in 2018, Dena Greenwood, was a naturalist, ornithologist, educator and guide who devoted much of her life to inspiring others to cherish the remarkably diverse habitats that we have in northern Arizona. Among her many achievement were working with the City of Sedona on the creation of the Sedona Wetlands Preserve which has become a premier bird sanctuary and birding destination. The continuation of Dena's lifelong dedication to sharing nature with others was the inspiration for this effort.
In recognition of these contributions, her family and friends created the Greenwood Fund to honor her memory and to continue her educational dreams.
Members of the Northern Arizona Audubon Society have created a course titled An Introduction to Natural History Field Studies and Yavapai College enthusiastically agreed to incorporate it into the curriculum at their Clarkdale Campus starting this September 5.
This four-session course will introduce students to the diverse habitats of the Greater Verde Valley region with special emphasis on understanding why these habitats exist where they do and the characteristic species found in each. Participants will visit the Bubbling Ponds and Sedona Wetlands sanctuaries and other natural areas, learn about the region's plants and animals, and get a hands-on introduction to the art of birding and other aspects of natural history field studies. The class will focus on identification of local species and stress the interdependence of species within each habitat discussed. Opportunities to participate in natural history studies through a variety of citizen science projects will also be discussed.
Those interested in signing up for the course can do so on the Yavapai College website. Please go to: _URL_
All participants completing the course will receive a $50 tuition subsidy from the Greenwood Fund. For further information, please contact Brent Bitz at _EMAIL_

Clean Intermittent Catheterisation (CIC) is a method of draining urine via a catheter inserted into the urethra, past the sphincter into the bladder. Once the urine is drained the catheter is removed. CIC is vital in reducing bladder pressure or draining residual urine, and therefore preserving kidney health. Correctly
performed, CIC can also reduce the risk of urinary tract infections (UTIs) and promote continence.
This guideline does not refer to children and adolescents with an acute short term requirement for bladder emptying such as post-operative urinary retention, or need for an indwelling urinary catheter. Please refer to the Indewelling Urinary Catheter

For dragons to breath fire is certainly possible to have happened. Today fireflies produce light, eels produce electricity and the bombardier beetle can produce fire. The bombardier beetle has a canon near his rear end where he can blast his enemies with chemicals that are 212 degrees Fahrenheit: the temperature of boiling water. How does the beetle do that? This beetle has compartments where he stores fiery chemicals. When these chemicals unite they explode. If a tiny beetle can possess such a sophisticated mechanism in its rear, then a dinosaur or dragon could also have had a similar mechanism that would allow it to breathe fire to defend itself.
In fact, some of the dinosaurs have compartments in their heads that are connected to their nasal passages. The Tyrannosaurs Rex has a head the size of a car but his brain was the size of a baseball. The rest of his head was full of these compartments connected to his sinuses. If he had these special chemicals stored in these hollow compartments, it is possible that he could have been a fire breathing dragon.
In addition, legends of fire breathing dragons have circulated around the world for centuries and throughout history. They are depicted in artwork and literature. Almost all cultures have dragon legends despite having had no contact with each other.

Integrated on-chip solid state capacitor based on vertically aligned carbon nanofibers, grown using a CMOS temperature compatible process
Artikel i vetenskaplig tidskrift, 2018
Complete miniaturized on-chip integrated solid-state capacitors have been fabricated based on conformal coating of vertically aligned carbon nanofibers (VACNFs), using a CMOS temperature compatible micro-fabrication processes. The 5 mu m long VACNFs, operating as electrode, are grown on a silicon substrate and conformally coated by aluminum oxide dielectric using atomic layer deposition (ALD) technique. The areal (footprint) capacitance density value of 11-15 nF/mm(2) is realized with high reproducibility. The CMOS temperature compatible microfabrication, ultra-low profile (less than 7 mu m thickness) and high capacitance density would enables direct integration of micro energy storage devices on the active CMOS chip, multi-chip package and passives on silicon or glass interposer. A model is developed to calculate the surface area of VACNFs and the effective capacitance from the devices. It is thereby shown that 71% of surface area of the VACNFs has contributed to the measured capacitance, and by using the entire area the capacitance can potentially be increased.


Vietnam to restrict surging scrap imports
For decades, China was one of the largest importers of waste and scrap materials. However, in the last few years, it has restricted imports on various types of waste and scrap material to reduce pollution. This has led to shipments being diverted to countries such as Vietnam and Malaysia, causing congestion at major ports.
In 2017, the total volume of scrap imported in Vietnam including iron, steel, plastics, and paper was twice that of 2016. Plastic scrap import during the first five months of 2018 is almost double compared to the total volume of imports in 2017. The rapid growth in imports has led to congestion in all the major ports in Vietnam, with around 6 000 containers stuck in Cat Lai Port and Hai Phong Port.
Apart from port congestion and environmental concerns, the major reasons for restricting imports and increasing inspections include the growing use of false permits, mislabeling of imports, and illegal imports.
The Vietnam Steel Association (VSA) has requested the government to allow steel producers to import 1.9 million tons of scrap for their industry annually. In addition, they have also proposed to extend licences of existing importers if they meet the environmental standards.
The association has highlighted the fact that steel produced from steel and iron scrap is an environmentally friendly process and produces only a fifth of the emissions compared to iron ore. Furthermore, as the domestic supply of metal scrap only meets 40 per cent of the industry demand, imports are a major source for steel producers.


text: Hello! I'm was wondering if there is anyone that could help a Marine Biologist finding a "simple" way to calculate the sound amplitude degradation with the increasing distance. For example a source produces a sound of 237 dB re 1μPa at 1m (x) and the speed of sound in the water is 1500m/s (y) at what distance is lower than 170 dB re 1μPa at 1m. Considering the sound propagation as in a plane, not in 3 dimensions and the only input I need is the source (in this example was 237 db re 1μPa at 1m) and the speed of water. If someone could help with this would be great! Would love to understand this matter a bit more!


Sylvia Plimack Mangold
From Wikipedia, the free encyclopedia
Jump to: navigation, search
Sylvia Plimack Mangold (born September 18, 1938) is an American artist, painter, printmaker, and pastelist. She is known for her representational depictions of interiors and landscapes.
Life and career[edit]
Plimack Mangold was born Sylvia Plimack in New York City, the daughter of Ethel, an office administrator, and Maurice Plimack, an accountant and businessman.[1][2][3] She grew up in Queens, and attended the High School of Music and Art in Manhattan, after high school she was accepted into the program at Cooper Union in 1956. She continued her studies at Yale University and graduated with a B.F.A. in 1961. In the same year she married Yale classmate and fellow painter Robert Mangold.
After studying at Yale with William Bailey and others, Plimack Mangold worked as a representational painter. Her paintings in the early 1960s were paintings of floors, walls and corners, compositions where mirror images were also introduced, making the space more complex. In the 1970s she added trompe l'oeil elements such as metal rulers and masking tape along the borders of the images. In the 1980s she introduced the images of the landscape to the canvas affixed by the image of masking tape. Eventually, the landscape image filled the entire canvas and focused on individual trees, their branches cropped so as to create the spaces between the limbs and branches of the trees. All the landscape paintings are done from observation. Even as the subject matter of Plimack Mangold's paintings has shifted, her work has always been based in perceptual realism, inviting viewers to observe from up close and mirroring her own process of observation.[4]
Mangold received a grant from the National Endowment for the Arts in 1975. Her work has been the subject of solo exhibitions at the Museum of Fine Arts, Boston, the Neuberger Museum of Art at the State University of New York at Purchase, the Albright-Knox Art Gallery, and the Wadsworth Atheneum in Hartford, Connecticut, and is represented in the aforementioned museums in Boston, Hartford, and the Brooklyn Museum of Art.[citation needed]
She is the mother of film director and screenwriter James Mangold, and a musician Andrew Mangold.

The Turbelle® controller is a device which is used to set the variable pump performance. It can provide a wave simulation, oscillation flow, an automatic search for the resonance frequency when the oscillation flow is used, and it is also equipped with a food timer. It can be directly connected to a Multicontroller. The pump is therefore able to operate together with other pumps, for example, in the high/low tide mode. If the Moonlight 7097.05 (not included in the scope of delivery) is attached to the Turbelle® controller, the night-mode operation will be activated automatically. If this controller is connected to a second controller with the 7092.300 cable, a further pump can be connected and controlled, for example, to provide a wave pounding simulation or an oscillating current. A third controller can be added using the Y-adapter cable 7090.300.

Bats of the genus Pteronotus (Chiroptera: Mormoopidae) are known to inhabit high-temperature roosts. This study examines the thermal ecology of a colony of three different species of Pteronotus in a sea cave on the Osa Peninsula of Costa Rica. Previous work found the cave to be inhabited by three species of the same genus: P. personatus, P. parnelli, and P. gymnonotus, and documented that temperatures in the cave at low tide with bats present can exceed 40° C. This high ambient temperature makes this cave one of the few locations where bats have been documented to roost at temperatures warmer than their body temperature. However, the cave fills with seawater during high tide, which potentially creates a cooling effect. We explored whether temperatures in the cave fluctuated significantly with tide levels and the presence or absence of roosting bats. Hobo data loggers were placed in the cave for several days to continually record changes in ambient temperatures within the different parts of the cave at different combinations of tides and bats. Upon entering the cave, temperatures of roosting individuals (during the day), and the cave ceiling (at night) were also recorded using an infrared thermometer.
Temperatures on the ceiling of the cave, which was entirely covered with roosting individuals, at low tide were measured at 40-41°C. However, during low-tides at night (with bats absent), temperatures were only 37-39°C in the equivalent parts of the cave. Ambient air temperatures collected by the Hobo data loggers detected no significant effect of tide levels (low vs. high) on ambient temperature. Results from sensors placed near the bottom of the cave showed significantly lower temperatures when bats were present, but when sensors were elevated ~8m, it was found that temperatures in the upper parts of the cave were significantly higher with bats present. These patterns are likely related to the properties of the cave walls to absorb and radiate heat generated by the bats. In the upper areas of the cave, where bats roost, the presence of bats clearly elevates temperatures. The genus Pteronotus may use these high temperatures as a means of thermal competition to exclude species with lesser heat tolerance from using the otherwise highly-desirable roosting habitat.

Preface: I've read this question about water preventing an initiation from occurring.
I understand why it's important to slowly add the alkyl halide to the dry ether and magnesium for exotherm control. But why is the first addition called an initiation and what's its purpose?
Is it just to confirm that the conditions are ready to continue slowly adding the rest of the reagent? I know it's a free-radical reaction, maybe that's where the term "initiation" comes from. But I've seen the reaction described as "self-sustaining" after the initiation, but it's not a chain reaction. Perhaps that's referring to a predictable reaction proceeding forward instead of stalling then blowing up your glassware.
The first step in the Grignard reaction involves transfer of an electron from the surface of the metal to the alkyl halide to form a radical anion. The radical anion then disproportionates into a free radical and halide anion. \begin{aligned} \ce{R−X + Mg &-> R−X^{•−} + Mg^{•+}}\\ \ce{R−X^{•−} &-> R^{•} + X^{−}}\\ \ce{R^{•} + Mg^{•+} &-> RMg^{+}}\\ \ce{RMg^{+} + X^{−} &-> RMgX}\\ \end{aligned}
When you take the magnesium out of the jar, the surface has a thin oxidation layer on it that prevents the initial electron transfer from occurring. We used to take one piece of magnesium and scratch it good with a knife to expose a clean, fresh magnesium surface. We would place this piece of magnesium in the flask (dry ether and the rest of the magnesium already added) and drip in a few drops of the alkyl halide. Without fail, within a minute or two, mild bubbling would be noticed (local ether boiling), which became vigorous as the initiation phase of the reaction "cleaned" the surface of other pieces of oxidized magnesium. After the vigorous bubbling started to subside we would drip in the remaining alkyl halide plus ether solution at a rate to maintain ether reflux. So the reaction does involve a free radical but the initiation phase really has more to do with removing the oxidation layer from all of the magnesium and allowing that initial electron transfer step to occur.
 - $\begingroup$ Good answer, I'd like to add a point to be considered: The initial electron transfer is usually slightly endothermic. In the initiation process you will usually need to add some energy - the warmth of the hand might do (depending on the used halid). After the reaction started, the formation of the Grignard is exotherm, hence providing enough energy to overcome the activation energy of the electron transfer. It will then proceed until the limiting reactant is used up - hence it is called self-sustained. $\endgroup$ – Martin - マーチン Jul 14 '14 at 7:15

 $\begingroup$ _USER_ That makes a lot of sense. My group has been performing Grignard reagent prep and reactions on and industrial scale, and your answer gives much needed perspective to why we have the initiation step, and how to troubleshoot it if it doesn't go right away. $\endgroup$ – tralston Jul 14 '14 at 15:57
 - $\begingroup$ _USER_ That's an interesting point. Thanks for explaining the self-sustaining aspect of the initation. $\endgroup$ – tralston Jul 14 '14 at 16:05
First, you are mixing magnesium metal with an alkyl halide. The product of this reaction is $\ce{R-Mg-I}$, where $\ce{R}$ is the alkyl group and $\ce{I}$ is the halide. It is called an initiation reaction because you first need to make the reactive compound.
Next, you add the alcohol to produce the product. Mixing an alkyl halide and an alcohol together will not yield the product you want.

Xcode: connecting interface elements to each other
Forum
App Development
Hi all! I'm getting into app development with Xcode, and have started this by reading a book on Objective-C development. This way I was able to familiarize myself with this programming language, and have been exclusively developing applications for the command line for this purpose. Now it's time for graphical applications, and I've been playing around with Interface Builder for the last few days. At this point, I neither hate nor love it, but I think it can mostly be handled once you kind of figure out how things are done. For example, I like how I can arrange interface elements using coordinates in the Size Inspector, run the application and then use my trackpad to verify elements are arranged in the way that I wanted. I've also been able to find out how to connect elements to code, so that I can program and process events and such. However, I am unable to figure out how to connect elements to each other. Basically, I'd like to put a label and a slider in a window, and the slider should update the value of the label. This is an exercise from a Cocoa book that I'm currently reading, since it apparently is possible to control-drag elements to each other in order to connect them. However, control-dragging is not possible with VO, and dragging an event from the Connections Inspector to the other element also doesn't seem to work. Please, could someone help me out here and tell me what I need to do to connect 2 elements to each other? Many thanks! Best wishes, Robin.

Hi, as for Objective-C learning, I read Programming in Objective-C, Fifth Edition by Stephen G. Kochan. It's a great book for learning Objective-C, and I think the author did a great job in explaining all the concepts of the programming language. Note that you will only be developing applications for the command line in this book, all the fancy stuff comes afterwards! As for learning Cocoa and designing applications with visual interfaces, I've found 'Learn Cocoa on the Mac, Second Edition' by By: Jack Nutting and Peter Clark. I haven't read too much of it yet, but it seems rather detailed and explanations seem thorough. My main problem right now really is dealing with Interface Builder issues, as I find the rest of Xcode rather easy to use. I should also say that the mentioned books are available online through _URL_. You will need a subscription with them to get access to their content, but if you're interested in learning programming languages and such I highly recommend them. Hope that helps! :-) Robin

Thanks for your research, but that's exactly the problem - you can't do control dragging with VO... That's just how you'd do this with a mouse or trackpad, but it can't be done using VO :-( Robin

Hi, robin24. I'm a sighted developer and have an app with a slider that updates a label. I'm not aware of any way to connect the slider to the label with a control-drag. I'd be curious to learn that this is possible if you can provide a specific citation. What I do is connect the slider to an IBAction, and then update the label there. I can provide specific code if you'd like.
Submitted by Anonymous Developer on Tuesday, July 16, 2013
Disclaimer: I'm a sighted developer, so I have no idea if what I'm about to describe here is doable with VoiceOver on a Mac. Here's one way I know of to connect Interface Builder elements to IBOutlets in your .h file. 1. Open NIB/XIB file in interface builder's standard editor. 2. Double-click the corresponding .h (header) file so that it opens in a new window. 3. In your header file, on the line which has your IBOutlet, to left of where the line number is listed by XCode, there is a small spot which you can drag (without control) onto your interface builder element in XCode's main window. This should allow you to connect Interface Builder element with the IBOutlet.

The studies are targeting key areas, such as reducing the environmental footprint of liquefaction facilities and the associated greenhouse gas emissions, according to a Siemens statement.
Targeted areas also include plant reliability, maintainability, regulatory compliance, and development costs.
The duo will explore different concepts such as the use of gas turbineand electric-driven compression trains in conjunction with single-mixed refrigerant and double-mixed refrigerant technologies.
Additonally, the partners will look into developing techniques to improve the efficiency of onsite power generation facilities such as heat recovery systems, inlet air chilling, supplementary firing, renewables integration, and battery storage.
The studies will also be exploring how to leverage digitalization and automation platforms to optimize plant design and achieve seamless project execution, the statement said.

Some of our readers were wondering how they might go about getting an ISBN. And what is it, anyway? Why is it important?
An ISBN is an International Standard Book Number. Up until the end of 2006 it was a 10 digit number, but from 1 January 2007 all ISBN numbers are now 13 digits long.
It is used by publishers, booksellers and libraries, for ordering, listing and stock control purposes. It enables them to identify a particular Publisher and allows the Publisher to identify a specific edition of a specific title in a specific format within their output.
In the past, ISBN numbers were 10 digits long but a new global standard, using 13 digits, has now been introduced. Under the new system which started on 1 January 2007, the 13 digits are always divided into five parts, separated by spaces or hyphens.
There is no legal requirement in the UK or Republic of Ireland for an ISBN and it conveys no form of legal or copyright protection. It is a product identification number. If you wish to sell your publication through major bookselling chains, or internet booksellers, they will require you to have an ISBN to assist their internal processing and ordering systems.
The ISBN also provides access to Bibliographic Databases such as BookData Online, which are organised using ISBNs as references. These databases are used by booksellers and libraries to provide information for customers. The ISBN therefore provides access to additional marketing tools which could help sales of your product.

What is Wide Awake Hand Surgery?
Wide awake hand surgery is surgery of the hand and wrist that is done without sedation, without a tourniquet, and without general anesthesia.
This new surgical approach involves injecting local anesthetic around specific nerves in the hand and wrist. There is no need for general anesthesia, hospitalization, and the associated risks, expenses, and inconveniences. Immediately after wide awake hand surgery, you can simply walk out of the operating room, go home or back to work - just like you would after a dental procedure.
As patients seek to minimize their medical costs and time away from work, wide awake hand surgery is in higher demand. The technique is safe, effective, efficient, and cost-effective, and results in high patient and surgeon satisfaction.
How is it different from other anesthesia?

Vinegar-natural source of nitrate to safeguard organic porkBy ANI
Sunday, November 14, 2010
WASHINGTON - Scientists have suggested that vegetable juice powder could provide a natural source of nitrate to serve as a curing agent for pork and still be classified as a natural source.
Consumers' enthusiasm for natural and organic food products extends to cured pork products such as hams, bacon and frankfurters. But products can't be labelled as natural or organic if they contain preservatives.
That means two traditional curing agents for pork - nitrite and nitrate - aren't allowed in natural and organic versions.
Iowa State University researcher Joe Sebranek said that taking a couple of natural antimicrobial ingredients - vinegar with lactate and vinegar with lemon powder - and incorporating them into the naturally cured pork products works.
The bacterial pathogens such as Listeria monocytogenes in the naturally cured pork products were inhibited, though still not to an equivalent level as in conventionally cured pork products.
"With natural and organic products you're limited to ingredients that qualify as natural or organic, respectively.If you use something that is traditionally used as a preservative, that's not permitted in a natural product," said Sebranek.
"With a naturally fermented vinegar product, you have a mixture of organic acids.
It's not typically used as a preservative but it provides some of the organic acids that are recognized antimicrobials. There's a mixture in that kind of a product that essentially provides a preservative effect," he added. (ANI)

According to the forecast of Guangxi Zhuang Autonomous Region Meteorological Bureau, in the next 10 days, the cold air force affecting South China has weakened, and the southerly warm and humid air flow has been continuously enhanced. The temperature in Guangxi has gradually recovered and the weather has warmed up. Before March 3, the average daily temperature in Guinan is 12 Above Â°C. The specific forecast is as follows:
From February 22 to 23, there was light rain in most areas of the cloudy day and fog in the morning. Temperatures in Japan vary from 9 to 12 Â°C in Guibei and 12 to 15 Â°C in Guinan.
From February 24 to 27, the north of Guangxi is cloudy, with scattered rain in some areas and cloudy south of Guinan. Temperatures in Japan vary from 13 to 16 Â°C in Guibei and 17 to 21 Â°C in Guinan.
From February 28th to March 2nd, there were some moderate to moderate rains in parts of northern Guangxi, and some heavy rains. There were light rains in other areas of our district.
1. Actively do a good job in planting dry land crops such as spring corn. It is estimated that the average daily temperature in Guinan before March 3 is above 12 Â°C, which is beneficial to the sowing and emergence of dryland crops such as spring maize. All localities should seize the favorable opportunity of warmer weather and moist soil, and actively do spring corn and spring cane. We will plant the dry land crops, strengthen the field management of the planted crops, combine the loosening of the soil, and timely check the seedlings, make up the seedlings, eliminate the insects and eliminate the disease.
2. Early rice is planted in time in Guinan and Youjiang River Valley. In late February, the southern Hunan and Youjiang River valleys will enter the suitable sowing period of early rice dry nursery and other cold-proof mites. The current warm and favorable weather should be used to carry out early rice planting and breeding work. Pay attention to the bottom water and make seedbeds and seeds well. Disinfect, cover the seed after sowing. Guizhong and Guibei pay attention to the selection of good early rice seeds, grasp the trampoline and fertilize, and prepare for breeding.
3. Actively do water storage in reservoirs and scientifically plan water use. With the full development of spring ploughing and spring work, the demand for water for agriculture is increasing. Therefore, all localities should seize all favorable conditions and actively carry out artificial precipitation enhancement operations, and take advantage of the favorable timing of rainfall to actively carry out water storage work in mountain ponds and reservoirs. And pay attention to the scientific plan to use water to ensure the smooth development of spring farming.

Mobile Benchmarks
As gRPC has become a better and faster RPC framework, we've consistently gotten the question, "How much faster is gRPC?" We already have comprehensive server-side benchmarks, but we don't have mobile benchmarks. Benchmarking a client is a bit different than benchmarking a server. We care more about things such as latency and request size and less about things like queries per second (QPS) and number of concurrent threads. Thus we built an Android app in order to quantify these factors and provide solid numbers behind them.
Specifically what we want to benchmark is client side protobuf vs. JSON serialization/deserialization and gRPC vs. a RESTful HTTP JSON service. For the serialization benchmarks, we want to measure the size of messages and speed at which we serialize and deserialize. For the RPC benchmarks, we want to measure the latency of end-to-end requests and packet size.
Protobuf vs. JSON
In order to benchmark protobuf and JSON, we ran serializations and deserializations over and over on randomly generated protos, which can be seen here. These protos varied quite a bit in size and complexity, from just a few bytes to over 100kb. JSON equivalents were created and then also benchmarked. For the protobuf messages, we had three main methods of serializing and deserializing: simply using a byte array, CodedOutputStream/CodedInputStream which is protobuf's own implementation of input and output streams, and Java's ByteArrayOutputStream and ByteArrayInputStream. For JSON we used org.json's JSONObject. This only had one method to serialize and deserialize, toString() and new JSONObject(), respectively.
In order to keep benchmarks as accurate as possible, we wrapped the code to be benchmarked in an interface and simply looped it for a set number of iterations. This way we discounted any time spent checking the system time.
interface Action {
 void execute();
// Sample benchmark of multiplication
Action a = new Action() {
 public void execute() {
 int x = 1000 * 123456;
Before running a benchmark, we ran a warmup in order to clean out any erratic behaviour by the JVM, and then calculated the number of iterations needed to run for a set time (10 seconds in the protobuf vs. JSON case). To do this, we started with 1 iteration, measured the time it took for that run, and compared it to a minimum sample time (2 seconds in our case). If the number of iterations took long enough, we estimated the number of iterations needed to run for 10 seconds by doing some math. Otherwise, we multiplied the number of iterations by 2 and repeated.
// This can be found in benchmark()
int iterations = 1;
// Time action simply reports the time it takes to run a certain action for that number of iterations
long elapsed = timeAction(action, iterations);
while (elapsed < MIN_SAMPLE_TIME_MS) {
 iterations *= 2;
 elapsed = timeAction(action, iterations);
// Estimate number of iterations to run for 10 seconds
iterations = (int) ((TARGET_TIME_MS / (double) elapsed) * iterations);
Benchmarks were run on protobuf, JSON, and gzipped JSON.
We found that regardless of the serialization/deserialization method used for protobuf, it was consistently about 3x faster for serializing than JSON. For deserialization, JSON is actually a bit faster for small messages (<1kb), around 1.5x, but for larger messages (>15kb) protobuf is 2x faster. For gzipped JSON, protobuf is well over 5x faster in serialization, regardless of size. For deserialization, both are about the same at small messages, but protobuf is about 3x faster for larger messages. Results can be explored in more depth and replicated in the README.
To benchmark RPC calls, we want to measure end-to-end latency and bandwidth. To do this, we ping pong with a server for 60 seconds, using the same message each time, and measure the latency and message size. The message consists of some fields for the server to read, and a payload of bytes. We compared gRPC's unary call to a simple RESTful HTTP JSON service. The gRPC benchmark creates a channel, and starts a unary call that repeats when it recieves a response until 60 seconds have passed. The response contains a proto with the same payload sent.
Similarly for the HTTP JSON benchmarks, it sends a POST request to the server with an equivalent JSON object, and the server sends back a JSON object with the same payload.
// This can be found in doUnaryCalls()
// Make stub to send unary call
final BenchmarkServiceStub stub = BenchmarkServiceGrpc.newStub(channel);
stub.unaryCall(request, new StreamObserver() {
 long lastCall = System.nanoTime();
 // Do nothing on next
 public void onNext(SimpleResponse value) {
 public void onError(Throwable t) {
 Status status = Status.fromThrowable(t);
 System.err.println("Encountered an error in unaryCall. Status is " + status);
 // Repeat if time isn't reached
 public void onCompleted() {
 long now = System.nanoTime();
 // Record the latencies in microseconds
 histogram.recordValue((now - lastCall) / 1000);
 lastCall = now;
 Context prevCtx = Context.ROOT.attach();
 try {
 if (endTime > now) {
 stub.unaryCall(request, this);
 } else {
 } finally {
Both HttpUrlConnection and the OkHttp library were used.
Only gRPC's unary calls were benchmarked against HTTP, since streaming calls were over 2x faster than the unary calls. Moreover, HTTP has no equivalent of streaming, which is an HTTP/2 specific feature.
In terms of latency, gRPC is 5x-10x faster up to the 95th percentile, with averages of around 2 milliseconds for an end-to-end request. For bandwidth, gRPC is about 3x faster for small requests (_PHONE_ byte payload), and consistently 2x faster for large requests (10kb-100kb payload). To replicate these results or explore in more depth, check out our repository.


text: A hybrid material point/finite volume method for the numerical simulation of shallow water waves caused by large dynamic deformations in the bathymetry is presented. The proposed model consists of coupling the nonlinear shallow water equations for the water flow and a dynamic elastoplastic system for the seabed deformation. As a constitutive law, we consider a linear elastic-non-associative plastic model with the Drucker-Prager yield criterion allowing for large deformations under undrained cases. The transfer conditions between these models are achieved by using forces sampled from the hydraulic pressure and the friction terms along the interface between the seabed soil and shallow water. A detailed description regarding the coupled algorithm for the hybrid material point/finite volume method is presented. Several numerical examples are investigated to demonstrate the performance of the finite volume method for simulations of shallow water flow and the material point method for capturing the large deformation process of the solid phase. We also present numerical simulations of an undrained clay column collapse that induced shallow water waves and a dam-break problem to demonstrate the excellent performance of the proposed hybrid material point/finite volume method.

One of the most impressive properties of the brain is its ability to sustain enormous amounts of damage while preserving neural function, as observed in many brain diseases and experimental manipulations. How does the brain compensate for damage, and what is the limit of this compensation?
We propose that the brain compensates optimally for neuron death. This preserves neural function to the greatest possible extent. We show that optimal compensation occurs in a variety of systems, including the occulomotor system, the cricket cercal system and the visual cortex. The mechanism underlying this compensation is balanced network dynamics; neuron death momentarily disrupts the balance of excitation and inhibition, but network dynamics automatically and rapidly recovers this balance, thereby restoring function. The limits of compensation depend on the nature of the disruption; once all the neurons that represent a particular signal dimension are silenced, rapid compensation for those signals becomes impossible. More generally, we propose optimal compensation as a computational principle; without it, optimal neural function will steadily degenerate as the typical wear and tear of a lifetime accumulates.

gmx rdf
Main Table of Contents VERSION 5.0.7
gmx rdf [-f [<.xtc/.trr/...>]] [-s [<.tpr/.tpb/...>]] [-n [<.ndx>]]
 [-o [<.xvg>]] [-cn [<.xvg>]] [-hq [<.xvg>]] [-nice ] [-b
The structure of liquids can be studied by either neutron or X-ray scattering. The most common way to describe liquid structure is by a radial distribution function. However, this is not easy to obtain from a scattering experiment.
gmx rdf calculates radial distribution functions in different ways. The normal method is around a (set of) particle(s), the other methods are around the center of mass of a set of particles (-com) or to the closest particle in a set (-surf). With all methods, the RDF can also be calculated around axes parallel to the z-axis with option -xy. With option -surf normalization can not be used.
The option -rdf sets the type of RDF to be computed. Default is for atoms or particles, but one can also select center of mass or geometry of molecules or residues. In all cases, only the atoms in the index groups are taken into account. For molecules and/or the center of mass option, a run input file is required. Weighting other than COM or COG can currently only be achieved by providing a run input file with different masses. Options -com and -surf also work in conjunction with -rdf.
If a run input file is supplied (-s) and -rdf is set to atom, exclusions defined in that file are taken into account when calculating the RDF. The option -cut is meant as an alternative way to avoid intramolecular peaks in the RDF plot. It is however better to supply a run input file with a higher number of exclusions. For e.g. benzene a topology, setting nrexcl to 5 would eliminate all intramolecular contributions to the RDF. Note that all atoms in the selected groups are used, also the ones that don't have Lennard-Jones interactions.
Option -cn produces the cumulative number RDF, i.e. the average number of particles within a distance r.
Options to specify input and output files:
Trajectory: xtc trr cpt trj gro g96 pdb tng
-s [<.tpr/.tpb/...>] (topol.tpr) (Input, Optional)

An opinion piece co-written by U of G Prof. Faisal Moola and environmental activist and scientist David Suzuki was published Nov. 29 in the Toronto Star.
In the article, Moola and Suzuki discuss the creation of a $85-million government trust to clean up industrial mercury contamination that has been poisoning people in the Grassy Narrows and Wabaseemoong First Nations in northwestern Ontario since the early 1960s.
The authors say that, besides financing cleanup efforts, the federal and Ontario governments must ensure that those suffering from mercury poisoning receive culturally appropriate treatment and care within their communities.
Newly appointed in the Department of Geography, Moola is an ecologist who studies conservation leadership and policy. He is also the David Suzuki Foundation's director general of Ontario and Northern Canada.


text: OBJECTIVES: Structured mentor-led training programmes permit the safe introduction of novice trainees to robotic-assisted laparoscopic prostatectomy (RALP). We outline the first description of parallel learning curves for individual surgical steps and quantify the relative difficulty of each step to propose an order of training in our structured mentoring programme. PATIENTS AND METHODS: A prospective ethically approved database was used to evaluate the operating times of each individual surgical step, in the first 150 RALP cases performed independently by a robotic-naive laparoscopic surgeon. Linear regression analysis was used to quantify the effect of surgeon experience on the operating time for each individual surgical step. RESULTS: Univariate linear regression analysis revealed significant reductions in operating time over the first 150 cases for all of the RALP steps, with the exception of the Rocco stitch. Multivariate linear regression analysis compensated for confounding variables and led to the identification of five surgical steps in which the operating time of each was significantly influenced by experience of the procedure. The most substantial improvement in operating time was seen in the bladder take down step. After taking into account the multivariate regression model, standardized univariate coefficients allowed an order of training to be identified for future RALP novices, of increasing complexity rather than order of surgery, beginning with the bladder take down step and ending with the vesico-urethral anastomosis. CONCLUSIONS: We can begin the training of new robotic-naive surgeons at simpler surgical steps, in which the greatest gains in expediency are made. We anticipate that identifying the more challenging surgical steps from this study and targeting training towards them may expedite our future trainees' proficiency at RALP.


take the average value of the pixel itself plus each of its eight neighbors (nine values in total):
let newValue [rows][cols]
 (image: [rows][cols]f32, row: i32, col: i32): f32 =
 unsafe
 let sum =
 image[row-1,col-1] + image[row-1,col] + image[row-1,col+1] +
 image[row, col-1] + image[row, col] + image[row, col+1] +
 image[row+1,col-1] + image[row+1,col] + image[row+1,col+1]
 in sum / 9f32
The function call newValue(image, row, col) computes the new value for the pixel at position (row, col) in image.
The alert reader will have noticed that newValue cannot be applied to pixels on the edge of the image - doing so would result in out-of-bounds accesses to the image array. We will take care to only call the newValue function with safe indices, but the Futhark compiler is sadly not yet smart enough to realise this - thus we are forced to use the unsafe keyword to prevent the insertion of bounds checks that would otherwise hinder parallelisation. If we did not use unsafe, the Futhark compiler would fail with an error message pointing at the problematic array access.
Now we can write the actual stencil function, which applies newValue to every inner element of a colour channel array. The edges are left unchanged:
let blurChannel [rows][cols]
 (channel: [rows][cols]f32): [rows][cols]f32 =
 map (\row ->
 map(\col ->
 if row > 0 && row < rows-1 && col > 0 && col < cols-1
 then newValue(channel, row, col)
 else channel[row,col])
 (0...cols-1))
 (0...rows-1)
You may have heard that branches are expensive on a GPU. While this is a good basic rule of thumb, what is actually expensive is branch divergence - that is, when neighboring threads take different paths through a branch. In our stencil, only the edge elements will take the false branch, and these are few in number compared to the interior.
Stencil computations usually have an outer (sequential) loop for applying the stencil several times. Our program is no different - we will apply the blurring transformation a user-defined number of times. The more iterations we run, the more blurred the image will become:
let main [rows][cols]
 (iterations: i32, image: [rows][cols][3]u8): [rows][cols][3]u8 =
 let (rs, gs, bs) = splitIntoChannels(image)
 let (rs, gs, bs) = loop (rs, gs, bs) for i < iterations do
 let rs = blurChannel(rs)
 let gs = blurChannel(gs)
 let bs = blurChannel(bs)
 in (rs, gs, bs)
 in combineChannels(rs, gs, bs)
Our main function is quite simple. We split the input image into three different channels, use a sequential loop to blur each colour channel the requested number of times, then recombine the resulting channel arrays into a single final image.
The Futhark loop construct merits an explanation: in the above function, we declare three loop variant variables, rs, gs, and bs. These take their initial values from the incidentally identically named variables in scope (but this is not in general requirement). The loop body then returns three values that become the values of the loop variant variables in the next iteration of the loop. In essence, the loop construct is just syntactical suger for a particularly simple (but common) pattern of tail-recursive function. However, the Futhark compiler is able to perform transformations involving loops that it cannot for recursive functions (although it does not perform any such for this simple program).
The three separate calls to blurChannel may seem wasteful, but the Futhark compiler is smart enough to fuse them together into a single GPU kernel that traverses the three colour channel arrays simultaneously. This is an instance of horisontal fusion.
Our Futhark program is now done. The full commented source code is located here: blur.fut. We can make it a little more useful by writing a small Python wrapper program for reading and writing PNGs: blur-png.py. We must compile blur.fut using the PyOpenCL backend:
$ futhark-pyopencl --library blur.fut
This produces a Python module blur.py which is then imported by blur-png.py. We can try it out on any PNG image, say, this illustration of the spirit of Futhark:
$ python blur-png.py gottagofast.png --output-file gottagofast-blurred.png
Which produces this slightly smushed image. We can also ask for a hundred iterations:
$ python blur-png.py gottagofast.png --output-file gottagofast-blurred.png --iterations 100
Which produces this blurry mess. Notice the edges - perhaps simply keeping them unchanged is not the best way to implement image blurring. Still, this program is a decent description of how to implement stencils in Futhark. For performance measurements on a slightly more complicated stencil, see HotSpot on the performance page.
Projects using Futhark
The majority of written Futhark code is probably still Futhark's own test and benchmark suites. However, there are some programs that have been written in Futhark because it was a good tool for the job, and not just to test the compiler. A possibly incomplete list:
Futcam is an application that applies stacks of interactively configurable filters to a webcam stream. Futhark is used to implement the filters.
tail2futhark is not written in Futhark itself, but is a code generator that produces Futhark, and serves as a component in an APL-to-GPU compilation pipeline. There is a blog post with more details.
Diving Beet is a falling sand game, which is a kind of simple particle simulator toy. Its main purpose is to produce pretty effects. There is a blog post with details and a video.
Futracer is a fairly slow brute-force ray tracer written in Futhark.

Soaring Temperatures Raise the Red Flag for Fire Danger in OregonSalem-News.com Weather
Temps from 95 to 100 degrees are expected for at least the next 2 days
(PORTLAND, Ore.) - Critical fire weather conditions are expected to develop across the Oregon Cascades and the southern Willamette Valley and adjacent foothills on Wednesday and Thursday.
The National Weather Service in Portland has issued a RED FLAG WARNING in effect from noon Wednesday to 11 p.m. Thursday for hot, dry and unstable conditions combined with dry fuels for fire weather zones.
Affected areas include Mt. Hood National Forest west of the Cascade Crest, Willamette National Forest west of the Cascade Crest, and the southern Willamette Valley and adjacent foothills.
Temperatures will be soaring from 95 to 100 degrees over the lowlands, and 80 to low-90's in the higher elevations.
Relative humidity will be 10-20% in many areas, and overnight recoveries will be limited along and above thermal belts. The combination of an increasingly hot, dry and unstable environment and very dry fuels may result in rapid growth of new or existing fires.
A RED FLAG WARNING means that critical fire weather conditions are either occurring now or will shortly. A combination of the above conditions can contribute to extreme fire behavior.

A major water supply project that will bring an end to severe watering restrictions in the Township of East Langley, British Columbia will be completed by the end of summer 2015.
The $33.5-million East Langley Water Supply project will provide clean, safe, and dependable drinking water to residents, businesses, and schools when it is completed. The 14-kilometre project will connect the communities of Aldergrove and Gloucester to Metro Vancouver's water system.
Kevin Larsen, the town manager of water resources and environment, told the Aldergrove Star that, "Connecting to Metro Vancouver's water system will provide a dependable water supply that will meet the needs of the area's growing population, while reducing pressure on local aquifers. The environment will benefit as local aquifers can recharge and be sustained into the future, and base flows to local streams and watercourses will increase."
More than 13 kilometres of the 14-kilometre water pipeline has already been installed and a new pump station has been completed in Murrayville. Only 800 metres of pipeline currently remain under construction.
For years, the Township of East Langley has had severe watering restrictions in the summer months to help preserve the water in its seven groundwater wells. Historical monitoring of groundwater levels in Aldergrove and Gloucester has shown a downward trend that indicates the current rate of groundwater extraction is unsustainable for the community. The existing wells are unable to meet the current peak summer flows as shown by the water restrictions that are in place.
The East Langley Water Supply is expected to be completed by August 7 and the surrounding areas will be re-vegetated and fully restored in the following months.

The Role of Recognition
Recognition has been a fundamental part of Scouting from its beginning. Done well, it is a powerful tool that can help leaders set goals, define accomplishments, encourage skill development, celebrate commitment and achievement, and inspire others to strive for similar success.
Effective recognition is essential to effective unit service:
- It provides clear definition of success: the attitude, skills, training and behaviors needed to perform effectively
- It helps identify and recruit volunteers to serve as commissioners
- It helps retain commissioners
For commissioners, effective recognition supports recruiting and developing a team that helps unit leaders start, build, and grow strong, sustainable units that will ensure every member of the BSA has a great Scouting experience.
While there are many definitions of "commission," they share common threads: a "Commission" is an authorization to act; an act of entrusting or giving authority; an appointment or assignment to a task or function.
In Scouting, only professional staff members and commissioners are eligible to be commissioned. Just as the wreath of service is a unique design element of their badges of office, commissioning is a unique opportunity for individuals in those positions to publicly commit to providing service in Scouting and to celebrate their commitment.
Commissioners are recruited and commit to serve one year at a time; a commissioning ceremony is a great opportunity to publicly formalize and celebrate their commitment.
For commissioners who are renewing their commitment to serve, a review of achievements over the past year and plans for the year to come (Assess – Plan – Act) provide great preparation for a commissioning ceremony.
Commissioning ceremonies – and preparation for them – help recognize and celebrate success and retain commissioners.
Everything needed to conduct commissioning ceremonies is just a click away: _URL_
Commissioner recognition and this awards and recognition website have three objectives:
- Establish recognition opportunities for all commissioners.
- Establish consistent requirements that incorporate the contemporary tools and techniques commissioners use.
- Provide easy access to information, including opportunities, requirements, progress records, certificates, and available recognition items.
There are three categories of commissioner awards and recognition:
- Recognition of an individual's commitment to serve.
- Recognition of an individual's development.
- Recognition of an individual's impact.
There are also three classifications of commissioner awards and recognition:
- Recognition from an individual's selection to serve.
- Recognition from an individual's application for an award.
- Recognition from an individual's nomination for an award.
Requirements and Progress Records
Requirements and progress records (or nomination forms) have been consolidated into a single pdf form that can be downloaded and saved to a local device. The forms can be completed by simply positioning the cursor in the first (or next desired) field and entering the applicable information. Applicants can track their progress and when all requirements are completed the progress record can be emailed (or printed and delivered) for review, approval and processing. Those wishing to nominate an individual for an award can follow a similar process.
Recognition certificates are also available as pdf forms. They can be completed online (or downloaded to a local device) and printed. Paper stock selection determines the final product. Using standard printer paper provides a good result; using higher quality stock (e.g., "resume' paper") provides a higher quality certificate suitable for framing.

As you might have known, the flash tube is filled with gas. While the flash is being charged, the charge current is limited and the gas becomes deionized. At the charging voltage, the internal resistance of the gas in the flash tube is high enough to prevent any flow of current from the main capacitor. However, by applying a trigger voltage, the gas will be ionized and becomes conducting, allowing the main capacitor to discharge rapidly through the gas. As a result, a brief flash of light is generated. The FZ-10 has an ISO hotshoe and uses the ISO 10330 based standard (i.e., less than 24 volts). See page 85 of your manual.
A trigger voltage is frequently generated by a spark coil mechanism which is usually triggered by the shutter contacts in the camera. This voltage is positioned on the low-voltage side of the spark coil so that it only appears on the flash contact. In this way, the user will not be injured accidentally, and the camera will not be damaged. This is especially important because digital cameras have circuits very sensitive to high voltage and strong current.
Some older flashes are known to have very high trigger voltage that may damage the circuits of a digital camera. Fortunately, most modern flashes have low to very low trigger voltages that can be safely used on digital cameras. Click here for a rather complete list of the trigger voltage of many flashes, studio strobes included. If you suspect your flash may have a very high trigger voltage, you may consider to use a simple device called safe sync. Click here for the details. Keep in mind that safe sync devices do not preserve the TTL capability of your flash. It does not matter because the FZ-10 does not do TTL flash metering.

 1. Consider a smooth projective surface $S\subset\Bbb P^N_{\Bbb C}$ which is a complete intersection of hypersurfaces of degrees $(d_1,..,d_{k\ge2})$ with $d_i\ge2$ for all i. Is it true that for such surfaces $c^2_1\le 2c_2$? (i.e. much better than BMY) At least asymptotically (i.e. for high enough $d_i$'s)?
Let $td_2$ be the top-dimensional Todd class, i.e. $td_2=\frac{c^2_1+c^2}{12}$. The inequality as above can be written as $c_2\ge 2^2td_2$.
 1. More generally, let $X\subset\Bbb P^N_{\Bbb C}$ be a smooth complete intersection of dimension $n$. Let $c_n$ and $td_n$ be its top-dimensional Chern and Todd classes. What are the known inequalities on $c_n$ and $td_n$? (I would like to have smth like $c_n\ge 2^n td_n$)
share|improve this question
I'd expect that there'd be a formula for $c_1$ and $c_2$ in terms of the degrees $d_i$ and then one could just check the resulting inequality directly. – Noam D. Elkies Jul 8 '11 at 17:35
You can find these formulas in Bart-Peters-Van de Ven, Chapter V – Francesco Polizzi Jul 8 '11 at 21:10
Yes, certainly, for a complete intersection in $\Bbb P^N$ the Chern and Todd classes can be computed explicitly. But the formulas are quite messy. I need the bound: $(-1)^n(c_n(X)-1)\ge 2^n(-1)^n\Big( td(T_X) ch(\mathcal{O}_X(-1))\Big)_{top.dim.}$ After computation of both sides I get some messy school-type inequality. No idea how to prove it in general. But in many numerical cases (of low dimension and codimension) I verified it. I wonder, is there some (indirect?) way to prove the bound without proving this numerical inequality? – Dmitry Kerner Jul 9 '11 at 12:03
An additional question. Suppose $S\subset\Bbb P^N$ is a smooth surface, "close to being a complete intersection". For example it is ACM or better arithmetically Gorenstein or even smth better. Do such surfaces satisfy the bound as above? An example not satisfying the bound would be of interest too. – Dmitry Kerner Jul 9 '11 at 12:05

By the formulae in [Barth-Peters-Van de Ven, Chapter V] one has, for a surface which is complete intersection of type $(d_1, \ldots, d_{n-2})$ in $\mathbb{P}^n$: $$c_1^2(X)= \big(\sum d_i-(n+1)\big)^2 \prod d_i,$$ $$c_2(X)=\bigg[\binom{n+1}{2}-(n+1)\sum d_i+\sum d_i^2 +\sum_{i < j} d_id_j \bigg]\prod d_i.$$
Then one obtains that the inequality $$c_1^2(X) \leq 2 c_2(X)$$ is equivalent to $$n+1 \leq \sum d_i^2,$$ and this is of course almost always true, since the right-hand term is $\geq 4(n-2)$. So the answer to $1.$ seems to be yes.
ADDED. Actually, this is also written in the book by Barth-PetersVan de Ven. In Chapter V, at the beginning of the Section "The Geography of Chern Numbers", they say:
" The simplest examples, like complete intersections and double coverings of $\mathbb{P}^2$, pratically always yield a point of $D_1$ [where $D_1$ is the region in the $(c_1, c_2)$-plane given by $c_1^2 \leq 2c_2$]. Indeed, for a long time only few examples were known of surfaces with Chern pairs $(c_1^2, c_2)$ in $D_2$ [i.e., such that $2c_2 < c_1^2 \leq 3c_2$]."
For your question in the last comment, instead, the answer is clearly no if $S$ is ACM. In fact, every smooth surface $S$ with $H^1(S, \mathcal{O}_S)=0$ is ACM for some embedding in the projective space. Now take for instance a fake projective plane. It satisfies $p_g(S)=q(S)=0$, so it is ACM, but $$c_1^2(S)=3c_2(S).$$

The square should be inside the parentheses, not outside. This is precisely the inequality in the work of Tsen and Lang. – Jason Starr Jul 9 '11 at 17:16
Uhm, I've made the computation again and I find the same result: just use $\sum d_i^2 +\sum_{i \neq j} d_id_j = (\sum d_i)^2$. But maybe I'm making some silly mistake... – Francesco Polizzi Jul 9 '11 at 17:50
The expression $(c_1^2-2c_2)/2$ is the second graded piece of the Chern character. The Chern character is both additive for short exact sequences and multiplicative for tensor products. Combined with the Euler sequence, it is easy to compute that the Chern character of a complete intersection $X$ in $P^n$ of type $(d_1,\dots,d_c)$ equals $(n+1)e^H - 1 - \sum_i e^{d_iH}$, where $H = c_1(O(1))$. In particular, $(c_1^2-2c_2)/2$ equals $1/2(n+1-\sum_i d_i^2) H^2$. So $c_1^2-2c_2$ is negative if and only if $n+1 < \sum_i d_i^2$. This is all done explicitly in my papers with de Jong. – Jason Starr Jul 11 '11 at 12:50
An easier way to see that the square has to be inside is to consider the case when the integers $d_i$ equal $1$. Then the "complete intersection" is really just a projective space of lower dimension. So you can compare your formula to the Chern classes of projective space (which are easy to compute from the Euler sequence). -- Best. – Jason Starr Jul 11 '11 at 12:53
Ok, thank you very much. I will check again the computation. Best. – Francesco Polizzi Jul 11 '11 at 12:55

Note: Normal system frequency of 60 cycles per second appear as blue. Green and red colors indicate higher than normal frequency.
A large region of electric systems, called the Western Interconnection, responded to the San Diego blackout on September 8 in less than a minute. A YouTube video vividly illustrates how changes in frequency across interconnected alternating current (AC) electric systems ripple across such a large area in a very short time.
The video shows the variation of frequency (the number of times per second that the electric charge reverses direction) in the Western Interconnection associated with the San Diego blackout on September 8. An event, which has still not been fully characterized, drove system frequency below 60 cycles per second for about 25 seconds. Interconnected electric systems in North America are designed to operate within a very narrow frequency band around 60 cycles per second (hertz). A frequency below 60 cycles per second indicates that instantaneous demand exceeds supply of electricity. After an extended period of insufficient supply (25 seconds), the system automatically shed load in San Diego. The blackout suddenly reduced system demand and frequency shot up well above 60 cycles per second.
The video uses data from a network of small, low-cost devices that plug into wall outlets. They reveal—for the first time—electric system dynamics during disturbances. Frequency, phase angle, and voltage of the power system are measured every few seconds and transmitted via the internet to computers at the University of Tennessee and Virginia Tech. The resulting GPS-synchronized wide-area network makes possible the geographic presentation of the data and system disturbance animations.
Frequency is shown as the vertical scale on the graph on the left and the color-coded map legend on the right. The red dots on the map are the locations of the monitors. Each line on the graph represents the frequency recorded over time by a monitor.
There are monitors in the Eastern Interconnection as well. The video below shows changes in electric system frequency in the 12 seconds after the loss of the two large North Anna nuclear units near Richmond Virginia due to the east coast earthquake on August 23.
Note: Normal system frequency of 60 cycles per second appear as red. Green and blue colors indicate lower than normal frequency.

 Replication and Rsync in Distributed Environments Overview
 IP/MPLSView includes third-party replication and remote synchronization (rsync) software packages that you can use to back up information for IP/MPLSView data and traffic collection. The replication and rsync utilities are designed to maintain backup servers with up-to-date versions of the files and the database of the primary servers they are backing up, and to replicate data in the event of a failure so the backup server can resume operation.
 The third-party rsync package backs up files from the primary application server to the backup application server and the Mongo database (MongoDB) and MariaDB replication packages keep the backup databases synchronized with the primary database. To synchronize the data, the replication and rsync software compares the data in the backup and primary databases and sends deltas in order to reduce overall data transfer.
 You can use the replication and rsync utilities to back up data in either of the following ways:
 You must install a separate license on the backup IP/MPLSView application server.
 Use the following utilities to administer the distributed servers:
 -—Sets up all IP addresses for all distributed servers.
 -—Stops all distributed servers.
 -—Checks the running status for all distributed servers.

Analysis of desert plant community growth patterns with high temporal resolution satellite spectra.
The study of a desert landscape consisting of C3 shrublands and C4 grasslands demonstrated the feasibility of mapping desertification processes on a regional scale using time-series satellite images, and demonstrated the potential for monitoring desertification processes through time. Fifteen meteorological satellite images of southern New Mexico, spread over the growing season of 1989, were processed to yield images of normalized difference vegetation indices. Computer classification of these images and comparison with extensive ground measurements confirmed the identification of the major classes of shrubland, grassland and mixed shrub and grass areas. The high-resolution temporal approach is shown to permit the accurate identification of vegetation types even under conditions of sparse vegetation cover. The phenologies of grassland and shrubland were revealed in the time series of satellite images. This feature of the data was used to overcome the tendency of the strong radiation signal from bare soil to mask the biomass signal. Comprehensive comparisons with ground measurements confirmed the accuracy of the biomass identification for local areas within the Jornada Experimental Range, and justified extrapolation of the classification to a larger adjacent area.

 Motorcycle active brake cooling
RaceBrake active brake cooling are made of 100% carbon fiber and allow to reduce the temperature of the calipers and brake oil by 35%.
This translates into better resistance of the braking system on all those tracks where the brakes are constantly put to the test and do not have time to cool down.
Anyone who goes to the track and has suffered the devastating effects of heat on the braking system knows how important a cooling system is to be able to achieve powerful and safe braking in all conditions.
It is no coincidence that this accessory is now increasingly widespread also on MotoGP and SBK that have braking systems worth tens of thousands of euros.
The much less performing amateur brake systems need extra help to dissipate heat, and this is the component that will make the difference on the temperature of your brake system.
condotti raffreddamento freni moto
Directly from the racing circuit to your bike
Competitions push everything to the limit, including the performance of the braking systems, which are increasingly put to the test.
This is demonstrated by the fact that the latest generation bikes are now more powerful, lighter and faster, but above all easier to ride.
The consequence is that what are called the average performances of the drivers have risen!
Higher speeds require better stopping distances and braking systems that go beyond their limits.
Every little improvement can really make a difference today.
Lowering the temperature of the calipers, pads and discs by a few degrees also allows the temperature of the brake fluid to be kept under control, guaranteeing constant braking even after numerous laps.
Often the very narrow and winding circuits, the small tracks, put a lot of stress on the brakes, not having the time to cool down.
Not infrequently it can happen to do about ten laps and find yourself with excessively long brake travel.
Our tests showed that the forced air ducts ensure cooling of the caliper area which reduces temperatures by up to 40%.
There are other similar accessories on the market, but they only serve to cool the brake disc.
The brake discs have a very large surface compared to their mass and are also in continuous movement, these two characteristics allow them to "self ventilate" themselves, ensuring that the temperature is always under control.
RaceBrake active brake cooling are the only cooling system that, by acting directly on the caliper as well as on the brake disc, allow to obtain 4 great advantages:
- lower the temperature of the brake disc
- lower the temperature of the caliper
- lower the temperature of the pads by pushing fresh air between the brake pads
- these 3 temperature reductions consequently lower the brake fluid temperature.
The particular shape of RaceBrake active brake cooling is not accidental but has been studied by doing various simulations.
The shape allows to obtain a forced fresh air circulation system already from 45 km / h.
At high speeds it is possible to obtain a thermal reduction with peaks of 40% lower than a braking system without RaceBrake active brake cooling.
condotti raffreddamento freni moto
Reduce with ease brake temperature
RaceBrake active brake cooling are made of carbon fiber obtained by autoclave formation in order to guarantee maximum resistance impact.
They are very simple to install, they are applied through their supports directly on the brake caliper.
This makes them universal when replacing the motorcycle or brake caliper or motorbike fork.
You can mount them anywhere.
There are two versions, one for 100 mm calipers, suitable for motorcycles such as Bmw HP4, S1000 RR, Ducati Panigale, Aprilia RSV4, MV Agusta F4, and a version for 108 mm calipers, such as Japanese motorcycles such as Yamaha R1, Kawasaki Zx- 10R, Suzuki Gsx-r 1000, Honda CBR 1000.
They can cool any brake caliper from the P4, M4, M50, GP4 series and are fully compatible with all Brembo brake calipers.

Meaning of the name Tristan
[ 2 syll. tris-tan, tr-ist-an ] The baby boy name Tristan is pronounced in English as TRIHS-TahN or in French as TRiyS-TAON †. Tristan is used chiefly in the English, French, German, Romanian, and Welsh languages, and its origin is Celtic. Drystan (Celtic) is an original form of Tristan. The name is derived from either the Celtic 'drest' (meaning din, riot, tumult), or else from the Latin 'tristis' via Old French. The form Tristram was first adopted by English speakers in the early 12th century, famous from the hero of the Celtic folklore tale of tragic romance between Tristram and Isolde. Tristram was a Cornish knight, one of the most noble of King Arthur's Round Table, while Isolde was an Irish princess; they fell in love with each other after unintentionally drinking a love potion meant for Isolde and her fiance, King Mark of Cornwall. The Old French derivation from 'tristis' is associated with the tragic nature of the legend. The legend was later retold in many notable works, including Lord Tennyson's poems Idylls of the King (1859), and Wagner's opera Tristan and Isolde (1865), further promoting the popularity of the name. The name Trista (English) is the female form of Tristan.
Tristan is a widely used name; it has 32 variants that are used in English and other languages. Variants used in English include Trestan, Trestin, Treston, Trestton, Trisan, Trisden, Trist, Tristain, Tristam, Tristán, Triste, Tristen, Tristian, Tristin, Triston, Tristram (used in Welsh too), Tristran, Tristrand, Tristyn, Trys, Tryst, Trysten, Trystian, Trystin, Trystn, Tryston, and Trystram. The contraction Tris, and the variant spelling Trystan (used in Welsh too) are other English forms. Drystan (Welsh), Tristano (Italian), and Tristão (Portuguese) are foreign variants of Tristan.
Tristan is popular as a baby name for boys. The name's popularity jumped from the 1970s up to the 1990s; before that, it was of sporadic use only. Its usage peaked modestly in 1996 with 0.273% of baby boys being given the name Tristan. It ranked at #68 then. The baby name has since experienced a loss in popularity. In 2015, its usage was 0.192% and its ranking #101, but it was nonetheless the most popular among all boy names in its group. In 2015, 9 times more boys were named Tristan than the next most popular name, Tristen. Tristan has mostly been a baby boy name, though in the past century it has also been used for girls. In 2002, the name Tristan was given to 13 times as many baby boys than girls.
Baby names that sound like Tristan include Thorstein, Thorsteinn, Thorsten, Torstein, Torsten, Trestan, Trestin, Treston, Trestton, Trisden, Tristain, Tristam, Tristen, Tristin, Triston, Tristyn, Trustin, Truston, Trystan, and Trystin.

I read a textbook on Quantum Groups by Kassel, and did not understand the following proof of well-definedness of $\Delta$ (comult.) and $\epsilon$ (counit) on $GL_q(2)$ and $SL_q(2)$: (pg 84)
The proof is sketchy and describes that to prove well-definedness on $SL_q(2)$, it suffices to show $$\Delta (det_q -1)=(det_q -1)\otimes det_q + 1\otimes (det_q -1)$$ (how?)
and $$\epsilon (det_q -1)=0$$
The part I don't understand is how to get the above two equations and how does that prove well-definedness.
Additional theorems that may help which are defined earlier are $\Delta (det_q)=det_q \otimes det_q$ and $\epsilon (det_q)=1$.
Sincere thanks for any help.

do you understand how the bialgebra structure on $M_q(2)$ works? – mebassett Dec 17 '12 at 13:26
1 Answer 1
up vote 2 down vote accepted
First, note that $SL_q(2)$ remains an algebra, because $M_q(2)$ is an algebra, and imposing the condition that $\text{det}_q = 1$ is the same as factoring out by the ideal generated by all multiples of $\text{det}_q -1$ (denoted by $I=(\text{det}_q-1)$. That it remains a coalgebra follows from the fact that $I$ is also a coideal, that is
$$\Delta(I) \subset SL_q(2) \otimes I + I \otimes SL_q(2)$$
We see that this is true from Kassel's computation of $\Delta(\text{det}_q -1)$. To get it, he just does the "add a copy, subtract a copy" trick. You should already know that $\Delta(\text{det}_q) = \text{det}_q \otimes \text{det}_q$. From the fact that the coproduct is linear you then have
$$ \Delta(\text{det}_q -1) = \text{det}_q \otimes \text{det}_q - 1 \otimes 1 $$
Doing the "adding and subtract a copy trick" we have
$$ \Delta(\text{det}_q) = \text{det}_q \otimes \text{det}_q - 1 \otimes \text{det}_q + 1 \otimes \text{det}_q - 1 \otimes 1$$
Then grouping like tensor products gives us Kassel's computation.
Since the coproduct was an algebra morphism before we passed to the quotient algebra, it remains an algebra morphism afterwards. You can verify this by writing down the appropriate commutative diagrams for $M_q(2)$ and $SL_q(2)$ and then linking them up with the canonical projection of $M_q(2)$ to its quotient. (If you need to verify this, I'd suggest you do it generally, with an any hopf algebra $H$ and quotient $H/I$ for a co/ideal $I$).
share|improve this answer
Sincere thanks! I don't get how Kassel computes $\Delta (det_q-1)$ though. Also, I don't really understand coideals. (my background is undergraduate, with highest level course being introductory galois theory) – yoyostein Dec 17 '12 at 16:26
I re-wrote it a bit more coherently, also describing coideals a tad bit more and explaining how he gets the computation. You should ensure you have a good idea of ideals and quotient rings if you don't have that already. coideals were described in ch3. I'm a 2nd year phd student and I find this hopelessly confusing myself. regards! – mebassett Dec 17 '12 at 22:09
a word of warning about kassel - it's a great book, but he tends to be a bit "over axiomatic" and it's a bit hard to see the forest through the trees sometimes. For instance, it's a lot easier to just compute $\Delta(\text{det_q})$ then to follow his chain of propositions. It helps to have a few other texts handy to cross-reference these things. – mebassett Dec 17 '12 at 22:15
thanks a lot! what other texts do you recommend? – yoyostein Dec 24 '12 at 13:19
I'm working through majid's "primer on quantum groups" (disclaimer: majid is my phd supervisor) along with kassel, and I have a few other texts handy, but they're harder for an undegrad to crack. feel free to email me about it, though. – mebassett Dec 28 '12 at 15:11

On July 30, 2012, the Indiana State Archives was presented with a hand-carved piece of Bedford limestone commemorating Tartan Day and the heritage of Scottish-Americans. California Stone Carver Frank Maurer has traveled the United States, providing numerous states archives with hand-carved stones specific to their state.
The Indiana Tartan Stone was the 23rd stone presented and features several symbols of Indiana including the Peony, Cardinal and Tulip Tree. In addition, the stone says "FII" denoting its carver and reads "Tartan Day _PHONE_." The top of the stone depicts the Wabash River and a Celtic Knot, which symbolizes eternity. The rear of the stone has the following inscription: "FII VI 2012" with a line under the "VI." This signifies that the stone was carved by Frank Maurer Jr. in June of 2012. The line under the "VI" indicates the use of a carbide chisel.
Tartan Day was first declared by the United States Senate as a Resolution in 1998 and later as a national day of recognition in 2008. April 6th was chosen as Tartan Day because the Declaration of Arbroath was written in Arbroath Abbey on that date in 1320, asking for the freedom of Scotland from England. Thomas Jefferson later used this document as a model for the Declaration of Independence.
The Indiana Tartan Stone will be available for use at events. Interested parties shall complete and submit State Form 54681 - Publish or Exhibit Materials from the Indiana State Archives.

Flow-based enzymatic synthesis of melatonin and other high value tryptamine derivatives: a five-minute intensified process†
To increase the uptake of biocatalytic processes by industry, it is essential to demonstrate the reliability of enzyme-based methodologies directly applied to the production of high value products. Here, a unique, efficient, and sustainable enzymatic platform for the multi-gram synthesis of melatonin, projected to generate around 1.5 billion U.S. dollars worldwide by 2021, and its analogues was developed. The system exploits the covalent immobilization of MsAcT (transferase from Mycobacterium smegmatis) onto agarose beads increasing the robustness and longevity of the immobilized biocatalyst. The fully-automated process deriving from the integration between biocatalysis and flow chemistry is designed to maximize the overall yields (58–92%) and reduce reaction times (5 min), overcoming the limitation often associated with bioprocesses and bridging the gap between lab scale and industrial production.
