Slang noun used and understood primarily by Brummies (people from Birmingham, UK), Yam Yams (people from the nearby area of the Black Country) and other Midlanders.
It is a noun used to describe the action of rolling forwards on the ground. It is often described as a 'forward roll' by the rest of the country.
Brummies will often say 'gambowl' instead of 'forward roll' and very few people outside of the city seem to understand this term.
The spelling of gambowl is a debate in itself, as it is rarely written and mostly used in speech. Variations of this spelling (gambowl) include: gambole, gambol and gamboul.
There is a Facebook group campaigning to promote awareness of the word, entitled 'it's not a foward roll, it's a ******* gambowl'.
That was a very nice gambowl you did just now.
(That was a very nice 'forward roll' you did just now.)
These gymnasts haven't done any gambowls yet!
(These gymnasts haven't done any 'forward rolls' yet!)

The following table provides a snapshot of new features introduced for Aperture™ in March 2017. Refer to the Aperture Administrator's Guide for more information on how to use the Aperture service.
Policy Violation Log Forwarding
The Aperture service can now forward Policy Violation logs to an external syslog server. This enables you to monitor Policy Violations from your external syslog server as they occur in your organization.
To guard against potential misuse, you can configure User Activity Rules to monitor user actions in Aperture SaaS applications. For example, you can create a policy that sends an email alert or creates a log entry when a user downloads an excessive number of reports or tries to access an SaaS application from a malicious IP address. Similar to content-based policy rules, user activity rules include a robust set of match criteria that allow you to precisely define which activities to track.
Auto-Complete for Policy Names in Advanced Search
When you search for policy.name in Advanced Search to filter assets, a list of existing policy names appears as you type. You can quickly pick a name from the list, instead of typing the full name.

Cell Picker is an automated high throughput cell filtering system. Utilizing motorized microscope and pump, with the help of digital camera and computer vision, Cell Picker is able to speed up the selection of a few cells in 107 from weeks to hours.
Being able to select few cells in many cells are alway playing an important role in advanced research in life science. It can be used in early screening in cancer and infant genetics test. However, this is always an error-prone, time consuming, tiresome process for researchers. Cell Picker proposed an innovation solution to the problem. Using automated lab equipment, cell picker greatly simplify the selection process and offload the replicate process to the machine.
Cell picker is made of a fully automated microscope, a motorized microscope platform, a micro manipulator with nano pipette and an electronic pump. A software I made control them to perform the desired task and show user an interaction interface.
Cell picker use a 2 step procedure with computer assistance to greatly speed up the process:
1) Cell Picker automatically dispense the diluted sample across a 384 well board. 2) Cell Picker take photo of each cells with user-defined fluorescence filters and display the result on an application, with suggestion of which one might contain cell. 3) Experimenter select the cell, collect the sample and place it on an in-house special made glass slide, with micrometer-sized wells.
4) Cell Picker wait cell to fall into wells and take pictures covers the whole slide with user-defined fluorescence filters, tile it and present it to the use. 5) Experimenter select the well that contains the cells contain cells. 6) Cell Picker collect all sample in the designated wells.
By adapting the procedure, cell picker greatly reduce time to select cell by first filter out most cells in the first procedure, and even less time is required for the experimenter. With the computer assistance, the experiment have higher accuracy and repeatability.

Spanish and British scientists intend to solve fisheries issues. (Photo: Pablo Lozano/IEO)
Spanish and British scientists assess fishery resources in Gibraltar
Friday, August 10, 2012, 03:40 (GMT + 9)
Scientists at the Oceanographic Centre of Cadiz of the Spanish Institute of Oceanography (IEO) and a UK fishing research specialist are collaborating in fisheries resources assessments in the Rock of Gibraltar.
The agreement was reached between the consultant hired by the Government of Gibraltar and researchers Ignacio Sobrino Yraola and Juan Gil Herrera, in a meeting in which the parties discussed the technical aspects based on the information available.
The experts analysed the series of abundance of key species and the seasonality of resources and identified the biological aspects depending on the type of species.
"The main problem encountered when analysing the information available consists in associating certain catches to a particular area, since they correspond to a total landed at auctions, regardless of the source," Sobrino explained.
"Deficiencies in the biological information of the main species (size, age, maturity, etc.) have also been identified, making it difficult to carry out an advisory process," the IEO researcher added.
In addition, the researchers also agreed to maintain contact in the future for possible clarifications on the information provided and likely future joint collaboration in future research projects assisting the fishing activity advisory in the area, as the statement of the IEO indicates.
Sobrino told the agency Europa Press that the British specialist Indrani Lutchman was provided with a summary that has enabled her to complete the information available in relation to the Spanish legislation on the subject.
"Of course, [the legislation] is in line with the EU law," he said, but he stressed that the "great interest" is focused on the exploitation pattern of the fleet.
For the expert, if the Gibraltar Government intends to implement management measures for fisheries in the future, it would be necessary to develop a research project aimed at resolving this issue in advance.

circulation of the foot, leading to more swelling, creating a vicious cycle. The vet might want to take an x-ray, but this will likely be a waste of money, even if the leg is broken. Most broken legs in rats can heal on their own, even breaks near the ankle joint that are floppy. You do not need to keep the rat isolated or quiet. Treat the pain and swelling with ibuprofen at a dose of 60 mg/lb twice a day. A compound fracture, where the bone breaks the skin, is much more serious and you must take your rat to a vet as the leg may need to be pinned or amputated, and treatment with an antibiotic (I recommend amoxicillin) is necessary.
If a swollen foot looks like it is puffed up with fluid, you can try soaking it in a warm Epsom salts solution, which will help to draw excess fluid out through the skin. The easiest way to soak a foot is to put the solution in a small baggie to put the rat's foot in.
I once had a rat who developed pain in his ankles from being on a wire floor without actually getting his legs caught. There was no swelling but he demonstrated pain by holding one foot up or limping on it. When I moved him to a cage without wire floors, the pain went away.
Here are pictures showing the
healing of a broken leg. This is Basil, with a compound fracture of the tibia
and fibula. The first picture was
just before surgery on
Sudden severe swelling, especially on the face, can occur from an injury or from an insect or spider bite. You can treat swelling with ibuprofen (see below). Or you can take your rat to the vet for a shot of dexamethasone. (Swellings can also be abscesses, which can appear fairly suddenly.)
An injury to the flap of the ear can result in a hematoma. This is a pocket of blood that forms under the skin. DO NOT try to lance a hematoma because this can cause profuse bleeding that is difficult to stop. A hematoma of the ear will eventually resolve on its own, although this may disfigure the ear. It this bothers you, you can have your vet repair the hematoma surgically.
Ibuprofen is an NSAID, a non-steroidal anti-inflamatory. It is a more effective pain killer and anti-inflammatory than aspirin or acetaminophen. It interferes with blood clotting but only while it is in the system. Chronic use can cause bleeding, ulceration, and perforation of the stomach. It can cause fluid retention and decreased blood flow to the kidneys, so is more risky to use in the elderly, with heart or kidney disease, or with diuretics. The dose is 15-60 mg/lb 2-4 times a day. Lower doses are for analgesia, higher for inflammation.
You can use you can either crush up a tablet or use liquid baby medications if they do not contain sorbitol, an artificial sweetener that rats hate. Sorbitol will be listed under the inactive ingredients. Most rats like berry flavored Motrin. To figure out the dose, look on the bottle to see how many mg/ml. Figure out how many ml to use to give your rat the proper number of mg. It's a good idea to give the rat a treat afterwards to mask the bad aftertaste that may cause your rat to refuse the medication the second time.
For tablets, you can grind them up into a fine powder on a small plate with a spoon. For capsules, pull the halves of the capsule apart and dump out the powder. Grind it up if necessary. You can then mix the powder in liquid or food.
To mix in food, mix the powder well and divide into little piles, each containing the proper dose. Then you can scrape a pile into the food. Some suggestions include baby food, pudding, mashed avocado, yogurt, brown sugar and carob powder, honey, peanut butter mixed with jelly, moistened graham cracker, non-fat cream cheese, margarine, Nutri-Cal, pasta sauce, and as a last resort, ice cream, frosting, cheesecake, or even butterscotch or chocolate syrup! Use only enough food to mask the taste of the medicine so your rat will eat it all immediately. Adding a bit of salt will help counter the bitter flavor of medicines. If your rat refuses to eat the doctored food voluntarily, those in paste form can be smeared on his mouth, or even on the backs of his ears so he will groom the paste off and eat it.
The dose most vets prescribe for rats is too low. Metacam (generic name meloxicam) is an NSAID, and therefore works the same way as ibuprofen. The liquid sold by vets is for dogs, and since dogs do not metabolize NSAIDs well, the dog dose is very low (only 0.1 mg/lb). Rats metabolize NSAIDs very well, in fact, so well that the dose of ibuprofen for inflammation in rats is 60 mg/lb 2-4 times a day. (Exotic Animal Formulary, AAHA, 1995, 2001 and Drug Dosage in Laboratory Animals, 3rd ed. Borchard et al, 1990)
By comparing the human dose of ibuprofen to that for rats, and then looking at the human dose of meloxicam (which is 7.5 to 15 mg a day), it appears that the best dose of Metacam for rats is 1 to 2.25 mg/lb. Since the concentration of the Metacam liquid is 1.5 mg/ml, a 1-lb rat would need 0.6 to 1.5 ml. In addition, although meloxicam is only given once a day to humans and dogs, because the rat's metabolism is so much higher, it needs to be given more often to rats. I recently talked with a rat owner giving Metacam to a rat with severe pain, and she reports that once a day was not often enough.
Because rats are so small, and not well adapted to heat, they can succumb to heat stroke quickly. Situations that can cause heat stroke include leaving your rat in the sun or outside in warm weather, too close to a heater, or on a heating pad. The symptoms of heat stroke can include drooling and lethargy or unconsciousness. The tail will be quite warm to the touch. You must quickly cool the rat by submerging her up to her neck in lukewarm water. Also encourage her to drink an electrolyte beverage or water containing some sugar and salt. If she doesn't recover quickly, rush her to your vet.
Shock & CPR
There are two types of shock we need to be concerned about: electrical shock and physiological shock. Electrical shock can occur when a rat chews through a power cord. Electrocution can cause unconsciousness and can also stop breathing. In this case, you must do mouth-to-nose respiration to start the breathing again.
Place your lips around the rat's nose and blow into her lungs. You will have to blow fairly hard, enough to make the chest expand, but not too hard. After blowing 2-3 times, check to see if breathing has started. If not, firmly massage the chest for a couple of seconds and then blow in their nose again. Alternate the chest massage with blowing into the lungs. Firmly slapping the body can also stimulate breathing. Do not give up too easily. You may have to work for several minutes to restore the breathing.
Electrocution can also cause burns, especially to the mouth. Burns are not always obvious on animals with fur so if your rat has been electrocuted, a veterinary exam is good precaution.
Physiological shock is a condition where the circulation system shuts down because of blood loss, extreme stress, or other failure of normal body systems, and is an extreme emergency. The symptoms include extreme lethargy, dull eyes, and low body temperature. Keep your rat warm and her head lower than her body while rushing her to the vet for an injection of dexamethasone and possible fluid therapy.
Diarrhea & Constipation
Diarrhea isn't common in rats, and is usually caused by sensitivity to a medication. If the diarrhea is severe, you may need to discontinue the medication. Occasionally, diarrhea can be caused by a temporary upset in the intestinal flora (good bacteria in the intestines) which can be treated with probiotics (good bacteria for the intestines). One source of probiotics is yogurt containing active cultures (check the label), but a better source is a probiotic product from a health food store, pet shop or feed store. Dose is not critical; you can't give too much. Mix it in soft food. If the rat is on an antibiotic, give the probiotics at least 2 hours before or after giving the antibiotic otherwise the antibiotic will kill the good bacteria. If the diarrhea is going to respond to the probiotics, you should see an improvement within a few days.
For sudden severe diarrhea, you can give Pepto-Bismol at 1 drop/oz body weight three times a day, or Immodium at 1/10 the human dose.
For a rat who isn't on any mediations, chronic diarrhea that doesn't respond to probiotics is most likely caused by a serious problem with the intestines. In young rats it can be caused by megacolon. In older rats the most common cause is something like intestinal cancer.
Constipation is usually caused by low water intake

The Seleucid was a Greek gladiator who fought in the Arena in Cyrene. He typically fought armed with a glaive.
In 47 BCE, he was challenged by the Medjay Bayek of Siwa, who witnessed him throwing a sword at one of the spectators in the arena. Bayek later defeated the gladiator with a spear and shield.
- The name Seleucid is a reference to the Seleucid Empire, possibly hinting that the gladiator originated from the state.
- It can be assumed the Seleucid's real name is "Antiogos" because of one of the commentator's lines before the fight: "Time has come for Antiogos, dragon of the Seleucid Empire!"

Finding animals with a name beginning with the letter Q can be difficult, but don't worry! We have you covered. Check out the creatures listed below.
The Quokka is a small marsupial native to Western Australia. It usually stays in its natural habitat and is comfortable around people, so if you are lucky enough to spot one there, why not take a selfie?
The Quoll is another type of marsupial found mainly in Australia and New Guinea, which comes in four varieties: Eastern, Northern, Western and Tiger Quoll. Unfortunately all species are either endangered or vulnerable due to human interference such as habitat destruction.
Lastly, the Queenfish is commonly found near coasts near tropical waters – mainly in southern India and Southeast Asia. This fish can grow up to 25 inches long; however it is often sold for food so look before purchasing one!

Hammerhead sharks are a species of shark found in tropical oceans worldwide. Their name is derived from the unusual shape of their head which gives them increased sensory ability to detect prey.
In the early 18th century, hammerhead sharks were hunted by various individuals, such as the pirates Edward Kenway and Adéwalé. The bones they collected from the sharks were profitable in this era of the West Indies, and Edward used them as crafting material for his second ammunition pouch and his shark hunter outfit.
During the Peloponnesian War, a heavy hammer that was inspired by and dedicated to the hammerhead sharks was made available to the Spartan misthios Kassandra through an Animus modification by Layla Hassan, an Assassin who relieved her memories.
Behind the scenes
In Assassin's Creed IV: Black Flag, hammerhead sharks can be hunted for "hammerhead shark bones". In reality, sharks do not have mineralized bones, only cartilage and connective tissue. These "hammerhead shark bones" are required materials for crafting two items: the pistol ammo pouch II and the shark hunter outfit. Two are needed for the pouch while one bone and one pelt of bull shark skin is needed for the outfit.

New sentencing guidelines that will see the courts take full account of the harm caused by offences such as arson attacks on historic buildings or criminal damage leading to severe disruption of public services were published today by the Sentencing Council.
For the first time, all courts in England and Wales will have formal guidance to ensure that they take account of:
- The full impact of arson or criminal damage such as vandalism on national heritage assets including listed buildings, historic objects or unique parts of national heritage and history.
- The economic or social impact of damaging public amenities and services such as a fire at a school or community centre, or criminal damage at a train station, which can adversely affect local communities or cause economic hardship to neighbouring houses or businesses.
- The effect on communities when an area's emergency services or resources are diverted to deal with an incident of criminal activity.
The guidelines acknowledge that harm can involve not only physical injury but long-term psychological effects, and that damage to property can be about more than just its financial value.
Judges and magistrates will also consider requesting reports to ascertain both whether the offence is linked to a mental disorder or learning disability in order to assess culpability, and whether any mental health disposal should be considered.
The guidelines, which come into effect on 1 October 2019, will help to ensure that sentencing by judges and magistrates will be consistent across the whole range of these offences. Limited guidance exists in magistrates' courts, but the new guidelines apply to all courts.
The new guidelines cover the following offences:
- Arson – criminal damage by fire
- Criminal damage / arson with intent to endanger life or being reckless as to whether life endangered
- Criminal damage where the damage has a value of more than £5000
- Criminal damage where the damage has a value of less than £5000
- Racially or religiously aggravated criminal damage
- Threats to destroy or damage property
Sentencing Council member Her Honour Judge Sarah Munro QC said:
"The Council's guidelines ensure that courts can consider all the consequences of arson and criminal damage offences, from a treasured family photo being destroyed to someone nearly losing their life and home in a calculated and vengeful arson attack."
Welcoming the new guidelines Mark Harrison, Head of Heritage Crime Strategy for Historic England, said:
"England's heritage can't be valued purely in economic terms. The impact of criminal damage and arson to our historic buildings and archaeological sites has far-reaching consequences over and above what has been damaged or lost.
"Damage to our heritage comes in many forms. Whether it be graffiti painted on the walls of a historic church, vandalism to the stonework of an ancient castle or causing a fire that devastates a Medieval barn or Victorian pier; these offences have a detrimental impact on both the historic property or site and the local community in which it is located.
"The new guidelines will help the courts identify all the relevant factors to include in their sentencing decisions as they will now be able to consider 'threats to cause criminal damage', 'the act of damage' and 'damage by fire'. It will also aid Historic England's work with the Police and Crown Prosecution Service when cases involve damage caused to heritage or cultural assets."
Neil Odin, Chair of the National Fire Chiefs Council Prevention Coordination Committee, commented:
"I fully support these new guidelines for dealing with arson attacks through the courts. Deliberate acts of arson are a blight on our local communities and have an economic impact on businesses.
"In addition, damage and the loss of historical buildings is disruptive and impacts on our vitally important heritage. Arson also increases demands on the already stretched resources of fire services across the country, which can result in diverting resources away from other incidents.
" It is worrying to see that there has been an upward trend of arson since 2014/15 and while we will continue with prevention work to reduce these figures, it is important the courts can deal with criminal damage appropriately, sending a clear message to other people."
Justice Minister Robert Buckland said:
"Beyond the financial cost to victims, arson and criminal damage are serious offences which can risk lives and leave lasting psychological harm.
"So it is right that courts have clear and consistent guidance when sentencing offenders to ensure punishments properly fit the crime."


The mythical tall cedar in Lebanon (Ezek 31:3-31:5)
"Consider a cedar
Of Lebanon!
It has fair branches.
It has forest shade.
It has great height.
Its top is
Among the clouds.
The waters nourished it.
The deep made it
Grow tall.
Its rivers flow
Around the place
It was planted,
Sending forth
Its streams
To all the trees
of the forest.
So it towered high
Above all the trees
Of the forest.
Its boughs grew large.
Its branches were long
From abundant water
In its shoots."
Yahweh, via Ezekiel, compared Egypt to a tall cedar tree in Lebanon. This majestic tree had fair branches in a forest shade. It was extremely tall so that its top reached into the clouds. Ezekiel seems to be referring to an ancient Babylonian myth about the deep abyss or a dragon from the watery chaos that made trees grow tall. Thus they would enter the heaven of the gods in the clouds. The nourishing water from this deep abyss made this cedar tree grow tall. Streams from this water abyss flowed all around the place where this tree was planted. Even the other trees in the forest were able to grow because of this water. Nevertheless, this high cedar tree towered over all the other trees in the forest, because it had large long branches, due to the abundance of water in its shoots.


(1859 - 1939)
George Elbert Burr (1859–1939) was an American printmaker and painter best known for his etchings and drypoints of the desert and mountain regions of the American West.
Burr was born in 1859 in Monroe Falls, Ohio. He studied at the Art Institute of Chicago for one winter, his only formal artistic training. Nevertheless, he enjoyed early success as a commercial artist, providing illustrations for Harper's, Scribner's Magazine, Frank Leslie's Weekly, and The Cosmopolitan. In 1892, he began a four-year project illustrating a catalog of Heber R. Bishop's collection of jade antiquities for the New York Metropolitan Museum of Art. This project, which involved producing etchings of over a thousand artifacts, paid well enough for Burr to embark on an extended tour of Europe with his wife upon its completion. Over the next five years, as they traveled in Italy, Germany, and the British Isles, Burr amassed sketches and watercolors that would provide the source material for his copperplate etchings of European scenes.
A few years after his return to the United States, an attack of the flu prompted Burr to move to Denver for the benefit of his health. It was there, during summers spent in a cabin studio in a steep wooded canyon with panoramic views of the Rocky Mountains, that Burr began to concentrate on the work that made him famous. In 1924 the artist settled in Phoenix, Arizona, where he would remain for the rest of his life. This change of scenery gave him the opportunity to round out his oevure of Western landscapes with expansive views of the Sonoran and Mojave deserts.
Today George Elbert Burr is widely considered to be one of the finest of the early 20th century American etchers. His prints are in a number of prominent collections including the Smithsonian American Art Museum, the British Museum, the French National Print Collection, Luxembourg Gallery, Victoria and Albert Museum, the New York Public Library and the Congressional Library in Washington, D.C.

Showing 3D Directional Sensitivity¶
The 3d_dtcwt_directionality.py script in the examples directory shows how one may demonstrate the directional sensitivity of the 3D DT-CWT complex subband coefficients. It computes empirically the maximally sensitive directions for each subband and plots them in an interactive figure using matplotlib. A screenshot is reproduced below:
There are some points to note about this diagram. Each subband is labeled sich that '1' refers to the first subband, '5' the fifth and so forth. On this diagram the subbands are all four apart reflecting the fact that, for example, subbands 2, 3 and 4 are positioned in the other four quadrants of the upper hemisphere reflecting the position of subband 1. There are seven visible subband directions in the +ve quadrant of the hemisphere and hence there are 28 directions in total over all four quadrants.
The source for the script is shown below:
#!/bin/python """ An example of the directional selectivity of 3D DT-CWT coefficients. This example creates a 3D array holding an image of a sphere and performs the 3D DT-CWT transform on it. The locations of maxima (and their images about the mid-point of the image) are determined for each complex coefficient at level 2. These maxima points are then shown on a single plot to demonstrate the directions in which the 3D DT-CWT transform is selective.

A wireless bus for stacked chips was developed by "utilizing inductive coupling among them. This paper discusses inductor layout optimization and transceiver circuit design. The inductive coupling is analyzed by a simple equivalent circuit model, parameters of which are extracted by a magnetic field model based on the Biot-Savart law. Given communication distance, transmit power, data rate, and SNR budget, inductor layout size is minimized. Two receiver circuits, signal sensitive and yet noise immune, are designed for inductive nonreturn-to-zero (NRZ) signaling where no signal is transmitted when data remains the same. A test chip was fabricated in 0.35-μm CMOS technology. Accuracy of the models is verified. Bit-error rate is investigated for various inductor layouts and communication distance. The maximum data rate is 1.25 Gb/s/channel. Power dissipation is 43 m W in the transmitter and 2.6 mW in the receiver at 3.3 V. If chip thickness is reduced to 30 μm in 90-nm device generation, power dissipation will be 1 mW/channel or bandwidth will be 1 Tb/s/mm2.

Where in the world are you?
The globe and maps at the orientation podium help visitors determine where the Manasquan Reservoir is. The information leads the visitor from Planet Earth right to the Reservoir's location in Monmouth County.
Window to the Past
Monmouth County's geologic history is revealed in a replica of a local stream. Erosion has exposed a cross-section of soil and the fossils trapped within it, some of which are 74 million years old. This area went through many physical changes as the sea level rose and fell several different times during the earth's past. Visitors can learn how fossils document these changes. This exhibit also includes a case of fossils that encourages closer inspection.
At home with the Muskrat family
Visitors explore the living arrangements of the muskrat as they crawl through a muskrat tunnel. They see the inside of a muskrat lodge and the nursery chamber of these unique creatures. Other animals with a similar need for water use many of the same materials to build their nests or homes. These wetland-nesting sites provide protection from many predators.

Useful Tips
Dutch Oven Cooking
1. Fewer hot coals on the bottom, and more hot coals on top.
2. In all methods the coals need arranged toward the outer perimeter of both the bottom, as well as the lid to avoid burning. Rotating the Dutch Oven and lid at various times during the cooking process, also helps avoid hot spots and burning food.
3. +3 UP -3 DOWN Method
Once you use it a few times, and get it in your head, you won't have to carry any type of chart. In general this method produces 350° in any diameter size Dutch Oven. Knowing the Diameter of your pot; for example, if you have a normal depth 10 inch Dutch Oven, you simply add 3 to the diameter for the top (10+3=13 coals). You then subtract 3 from the diameter for the bottom (10-3=7 coals).
Rule of thumb for additional heat is; each additional coal added to the top only, will increase the internal temperature an additional 20 degrees.
Getting Latitude / Longitude from Google Maps
 1. To begin search for your desired location as you normally would.
 2. Next, right click the red "A" pin displayed on the map. Select What's here?
Conversely, if you have a lat, long combination you can plug that into Google Maps to show a location: 43.27069053158456, -75.28080940246582

Boeing robot supplier Kuka Aerospace to open Everett plant
Send this story to a friend
Boeing's future is in robots, and Kuka Aerospace, the automation company Boeing has been working with, plans to open a 29,000-square-foot facility in Everett.
The new plant, which will employ about 75 people, will be Kuka Aerospace's first U.S. plant outside Michigan.
Plans for the plant signal the growing partnership between Kuka and Boeing, as the latter moves toward increasing automation of its aircraft assembly.
Location of the plant in Everett also could boost automation of other aerospace suppliers – and possibly companies in other industries – in Washington. The implications of this are complex because, while automation inherently replaces people, it also can keep companies competitive against competition from low-wage countries, and thus generate other Puget Sound-area jobs.
"This is exactly what needs to happen," said Alex Pietsch, head of the state's aerospace office. "We know aerospace is moving toward automation, learning lessons from automotive. To have Kuka locate here will help Washington be a leader as manufacturing techniques continue to evolve."
Boeing and Kuka have been working on what they're calling the Fuselage Automated Upright Build (FAUB) process at a developmental facility in Anacortes, Wash.
The FAUB process will allow Boeing to keep fuselages upright during assembly by taking advantage of the fact that working overhead is no problem for robots while it's difficult for people.
The new Kuka center will also service other Kuka customers on the West Coast.
Kuka Aerospace is based in Sterling Heights, Michigan, and is in turn part of the Kuka Systems Group.

\mathcal D} \mu(s) = \frac{1}{\zeta(s)}}, {{\mathcal D} \lambda(s) = \frac{\zeta(2s)}{\zeta(s)}} that extend meromorphically into the critical strip. In contrast, the Matomaki-Radziwill theorem does not rely on such meromorphic continuations, and in fact holds for more general classes of {1}-bounded multiplicative functions {f}, for which one typically does not expect any meromorphic continuation into the strip. Instead, one can view the Matomaki-Radziwill theory as following the philosophy of a slightly different approach to multiplicative number theory, namely the pretentious multiplicative number theory of Granville and Soundarajan (as presented for instance in their draft monograph). A basic notion here is the pretentious distance between two {1}-bounded multiplicative functions {f,g} (at a given scale {X}), which informally measures the extent to which {f} "pretends" to be like {g} (or vice versa). The precise definition is
Definition 5 (Pretentious distance) Given two {1}-bounded multiplicative functions {f,g}, and a threshold {X>0}, the pretentious distance {\mathbb{D}(f,g;X)} between {f} and {g} up to scale {X} is given by the formula
\displaystyle \mathbb{D}(f,g;X) := \left( \sum_{p \leq X} \frac{1 - \mathrm{Re}(f(p) \overline{g(p)})}{p} \right)^{1/2}
Note that one can also define an infinite version {\mathbb{D}(f,g;\infty)} of this distance by removing the constraint {p \leq X}, though in such cases the pretentious distance may then be infinite. The pretentious distance is not quite a metric (because {\mathbb{D}(f,f;X)} can be non-zero, and furthermore {\mathbb{D}(f,g;X)} can vanish without {f,g} being equal), but it is still quite close to behaving like a metric, in particular it obeys the triangle inequality; see Exercise 16 below. The philosophy of pretentious multiplicative number theory is that two {1}-bounded multiplicative functions {f,g} will exhibit similar behaviour at scale {X} if their pretentious distance {\mathbb{D}(f,g;X)} is bounded, but will become uncorrelated from each other if this distance becomes large. A simple example of this philosophy is given by the following "weak Halasz theorem", proven in Section 2:
Proposition 6 (Logarithmically averaged version of Halasz) Let {X} be sufficiently large. Then for any {1}-bounded multiplicative functions {f,g}, one has
\displaystyle \frac{1}{\log X} \sum_{n \leq X} \frac{f(n) \overline{g(n)}}{n} \ll \exp( - c \mathbb{D}(f, g;X)^2 )
for an absolute constant {c>0}.
In particular, if {f} does not pretend to be {1}, then the logarithmic average {\frac{1}{\log X} \sum_{n \leq X} \frac{f(n)}{n}} will be small. This condition is basically necessary, since of course {\frac{1}{\log X} \sum_{n \leq X} \frac{1}{n} = 1 + o(1)}.
If one works with non-logarithmic averages {\frac{1}{X} \sum_{n \leq X} f(n)}, then not pretending to be {1} is insufficient to establish decay, as was already observed in Exercise 11 of Notes 1: if {f} is an Archimedean character {f(n) = n^{it}} for some non-zero real {t}, then {\frac{1}{\log X} \sum_{n \leq X} \frac{f(n)}{n}} goes to zero as {X \rightarrow \infty} (which is consistent with Proposition 6), but {\frac{1}{X} \sum_{n \leq X} f(n)} does not go to zero. However, this is in some sense the "only" obstruction to these averages decaying to zero, as quantified by the following basic result:
Theorem 7 (Halasz's theorem) Let {X} be sufficiently large. Then for any {1}-bounded multiplicative function {f}, one has
\displaystyle \frac{1}{X} \sum_{n \leq X} f(n) \ll \exp( - c \min_{|t| \leq T} \mathbb{D}(f, n \mapsto n^{it};X)^2 ) + \frac{1}{T}
for an absolute constant {c>0} and any {T > 0}.
Informally, we refer to a {1}-bounded multiplicative function as "pretentious'; if it pretends to be a character such as {n^{it}}, and "non-pretentious" otherwise. The precise distinction is rather malleable, as the precise class of characters that one views as "obstructions" varies from situation to situation. For instance, in Proposition 6 it is just the trivial character {1} which needs to be considered, but in Theorem 7 it is the characters {n \mapsto n^{it}} with {|t| \leq T}. In other contexts one may also need to add Dirichlet characters {\chi(n)} or hybrid characters such as {\chi(n) n^{it}} to the list of characters that one might pretend to be. The division into pretentious and non-pretentious functions in multiplicative number theory is faintly analogous to the division into major and minor arcs in the circle method applied to additive number theory problems; see Notes 8. The Möbius and Liouville functions are model examples of non-pretentious functions; see Exercise 24.
In the contrapositive, Halasz' theorem can be formulated as the assertion that if one has a large mean
\displaystyle |\frac{1}{X} \sum_{n \leq X} f(n)| \geq \eta
for some {\eta > 0}, then one has the pretentious property
\displaystyle \mathbb{D}( f, n \mapsto n^{it}; X ) \ll \sqrt{\log(1/\eta)}
for some {t \ll \eta^{-1}}. This has the flavour of an "inverse theorem", of the type often found in arithmetic combinatorics.
Among other things, Halasz's theorem gives yet another proof of the prime number theorem (1); see Section 2.
We now give a version of the Matomaki-Radziwill theorem for general (non-pretentious) multiplicative functions that is formulated in a similar contrapositive (or "inverse theorem") fashion, though to simplify the presentation we only state a qualitative version that does not give explicit bounds.
Theorem 8 ((Qualitative) Matomaki-Radziwill theorem) Let {\eta>0}, and let {1 \leq H \leq X}, with {H} sufficiently large depending on {\eta}. Suppose that {f} is a {1}-bounded multiplicative function such that
\displaystyle \frac{1}{X} \int_X^{2X} |\frac{1}{H} \sum_{x \leq n \leq x+H} f(n)|^2\ dx \geq \eta^2.
Then one has
\displaystyle \mathbb{D}(f, n \mapsto n^{it};X) \ll_\eta 1
for some {t \ll_\eta \frac{X}{H}}.
The condition {t \ll_\eta \frac{X}{H}} is basically optimal, as the following example shows:
Exercise 9 Let {\varepsilon>0} be a sufficiently small constant, and let {1 \leq H \leq X} be such that {\frac{1}{\varepsilon} \leq H \leq \varep


text: An apparatus has been developed for investigation of hydraulic conductivity of frozen soils. The test procedure is isothermal and involves the passage of water from one reservoir into the frozen sample and out of the frozen sample into a second reservoir. The water in the reservoirs remains unfrozen because it contains dissolved lactose. The concentration of lactose is such that, initially, the water in the reservoirs is in thermodynamic equilibrium with the water in the soil. On application of pressure to one reservoir a known hydraulic gradient is established and flow takes place. Flow is shown to vary linearly with hydraulic gradient. The hydraulic conductivity coefficient depends on soil type and temperature and is related to the unfrozen water content. At temperatures within a few tenths of 0°C the coefficient apparently ranges from 10−5 to 10−9 cm sec−1, and decreases only slowly below about −0·5°C. Soils known to be susceptible to frost heave are shown to have significant hydraulic conductivities well below 0°C.

The Difference Between Polyethylene Glycol and Ethylene Glycol
Time:2021-06-05
The Difference Between Polyethylene Glycol and Ethylene Glycol
Although the difference between polyethylene glycol and ethylene glycol is only one word, there is a big gap between their properties and applications. Welinks specializes in the production of PTMEG (Polytetramethylene Ether Glycol) in China.
1. Polyethylene glycol
Chemical structure: HO(CH2CH2O)nH, polymerized from ethylene oxide.
Polyethylene glycol-properties and uses
Polyethylene glycol is non-toxic, non-irritating, has good water solubility, and has good compatibility with many organic components. They have excellent lubricity, moisture retention, dispersibility, adhesives, antistatic agents and softeners, etc., and are used in cosmetics, pharmaceuticals, chemical fibers, rubber, plastics, paper, paint, electroplating, pesticides, metal processing and food processing, etc. There are extremely wide applications in the industry.
The Difference Between Polyethylene Glycol and Ethylene Glycol
2. Ethylene glycol
Ethylene glycol, also known as "glycol", "1,2-ethylene glycol", abbreviated as EG. The chemical formula is (HOCH2)₂, which is the simplest diol. Ethylene glycol is a colorless, odorless, sweet-tasting liquid, and it is toxic to animals. The human lethal dose is estimated to be 1.6 g/kg. Ethylene glycol can be miscible with water and acetone, but it is less soluble in ethers. Used as a solvent, antifreeze and raw material for synthetic polyester. Polyethylene glycol (PEG), a high polymer of ethylene glycol, is a phase transfer catalyst and is also used for cell fusion; its nitrate ester is an explosive.

The whole of the Hepburn Shire region was founded on gold and nowhere is the impact of this foundation more prominent than in the cosy town of Creswick.
The town includes one of the most impressive collections of heritage architecture, with buildings that owe their grandeur to the boom times of gold.
Exuding the best of the Goldfields and Spa Country regions, Creswick is surrounded by lush forests, many of them thick pine and eucalyptus plantations.
Adding to Creswick's history, this town is Australia's birthplace of reforestation. John La Gerche began re-planting forest areas ravaged by mining activity in 1882. Today, much of La Gerche's work survives around Creswick including magnificent plantings lining local streets.
The long established plantations date back more than 100 years ago, many of which were first established when the Victorian School of Forestry opened in 1910. It was the first institution set up in the State to train and accredit young foresters.
Explore the inspiration and birthplace of noted artist Norman Lindsay and his other family members. Five of the 10 children of Dr.Robert Lindsay went on to become leaders in the Australian artistic community- Percy, Lionel, Norman, Ruby and Daryl became noted artists and writers. Three of Norman's novels re-create the town a century ago, namely Saturdee, Red Heap and Halfway to Anywhere.)
Take in a round of golf at the local championship golf course or get yourself lost in an intricate living maze created from hundreds of flowering plants.
Creswick is packed full of attractions but without the hustle and bustle of nearby tourist destinations. Great scenery and a relaxed feel – without any of the parking problems.

Expand description
Expands to the column number at which it was invoked.
With line! and file!, these macros provide debugging information for developers about the location within the source.
The expanded expression has type u32 and is 1-based, so the first column in each line evaluates to 1, the second to 2, etc. This is consistent with error messages by common compilers or popular editors. The returned column is not necessarily the line of the column! invocation itself, but rather the first macro invocation leading up to the invocation of the column! macro.
Examples
let current_col = column!();
println!("defined on column: {current_col}");
column! counts Unicode code points, not bytes or graphemes. As a result, the first two invocations return the same value, but the third does not.
let a = ("foobar", column!()).1;
let b = ("人之初性本善", column!()).1;

Rick Stein's Cornwall episode 15: As Rick's Cornish odyssey comes to an end, he takes a city break in Truro, where he discovers an unusual ghost story and tours the magnificent cathedral.
Deep in the Cornish countryside is a family passionate about offal, who prepare Rick a delicious meal of pickled ox tongue and beef heart tacos. In Cornwall's most northerly parish, Rick tells the story of an eccentric vicar, Robert Stephen Hawker, who would retrieve and bury the bodies from nearby shipwrecks in his church, and who is credited with writing what has become Cornwall's unofficial national anthem.
In this new series Rick Stein reveals the Cornwall that he knows and loves: a unique part of the British isles with a strong sense of identity and a history rooted in its Celtic past. With his famous natural inquisitiveness, Rick shares the road less travelled – championing the food, history, music, art and culture of the county many locals argue should be a country in its own right.
Rick Stein's Cornwall episode 15 recipe:
Butterflied lamb with herby lemon and paprika marinade
This leg of lamb can be cooked on the barbecue or in the oven. Serve simply with potato wedges and greens for a laid-back meal with friends. Reduce the dried red chilli flakes if you prefer a milder marinade.
- To prepare the lamb, turn the leg over to the point where the bone runs closest to the surface. Using a sharp knife, split the meat along the bone and ease it away from the bone along both sides, leaving the bone as clean as possible. At the fatter end of the joint, there is a group of smaller bones, so continue to cut around them too until you can lift all the bones from the meat and are left with a butterfly shaped, bone-free joint. Trim away any excess fat and sinew. Lay a piece of cling film over the meat and bash the surface with a rolling pin to flatten the thick sections lightly. The meat should be an even thickness throughout.
- Mix the marinade ingredients together. Rub the marinade all over the lamb and set aside in a roasting tin, skin-side up, for about 30 minutes.
- Preheat the oven to 222C/200C Fan/Gas 7.
- Roast the lamb for 15 minutes, reduce the temperature to 180C/160C Fan/Gas 4 and roast for a further 15 minutes. This will give you pink lamb, if you would rather it slightly less so, cook for a further 5 minutes. Remove from the oven and cover with foil. Rest for at least 15 minutes. Place on a board before carving into thick slices.
- Serve with potato wedges, steamed green vegetables and some of the meat juices.

Aortic pulse wave velocity, a measurement of the flow pulse traveling along aorta as a surrogate for aortic compliance, can be assessed using a single plane breath-hold phase contrast imaging technique. Accurate determination of the time delay (Δ;t) between flows in ascending and descending aorta is critical. Various approaches have been studied for & Δ;t, including measuring the intervals between flow onset points, between maximal flow points, and between parallel upslopes after least squares fittings. We compared four automated approaches for time delay detection and evaluated their effects on aortic compliance and their relationship to age in normal volunteers.

Field Biology Laboratory
The field biology laboratory is not only a space for the continuing study of the flora and fauna of North Carolina, but is also a rich source of archival materials collected over many decades. The lab contains a collection of study skins and mounts of birds native to North Carolina, and a collection of bird nests from the Piedmont region. This laboratory houses two historical collections of bird eggs gathered in the 1800s, including the T. Gilbert Pearson egg collection. In addition, students have access to a herbarium of North Carolina plants, and reference collections of preserved reptiles, amphibians, and mammal skulls of species native to North Carolina and beyond.
Anatomy and Physiology Laboratory
Students investigate various aspects of human physiology using computer-based software for recording electrocardiograms, electromyograms, and electroencephalograms. Advanced studies in neuroscience include the recording of individual neuronal action potentials. An associated laboratory for field studies in fisheries biology houses a complete array of equipment for the investigation of aquatic ecology, limnology, and ichthyology.
Microbial Genetics and Molecular Biology Facility
Standard and advanced equipment in the molecular biology and microbial genetics lab provide students with the tools for the study of the phylogenetic relationship between microbial organisms and the molecular analysis of signaling processes in nematodes. In their independent research projects, students utilize instrumentation for the growth of organisms under a variety of conditions, and the isolation, purification and quantification of genomic DNA. Students routinely utilize the techniques of PCR, Pulsed-field Gel electrophoresis, fluorescent microscopy, recombinant DNA technologies and RNAi. The department has two fully-equipped laboratories dedicated to independent, student research projects.
Forensic Biology Laboratory
The forensic biology laboratory supports advanced forensics students in Molecular Cell Biology and Forensic Anthropology. Students pursue the identification of drugs and toxins utilizing the gas chromatograph-mass spectrograph, which provides definitive identification of these substances. The laboratory is also where students investigate a variety of topics related to cause of death, e.g., identification of diatoms related to deaths by drowning, and skeletal damage due to ballistics, cutting and blunt force trauma. The highlight of the Forensic Anthropology course, the investigation of clandestine graves, utilizes the equipment and archival materials of the forensic biology lab for this capstone experience in forensics.
Forensic Chemistry Laboratory
Students utilize research-grade microscopes for the analysis of trace forensic evidence, and explore a variety of chemical methods for developing latent fingerprints. Forensic chemistry students employ the fully automated Shimadzu QP 2010 gas chromatography-mass spectrograph for the definitive identification of illegal drugs. Another major focus of the laboratory experience is the preparation of forensic DNA Profiles. After DNA extraction, forensic STR loci (including the CODIS loci) are amplified with the 9700 Thermocycler. Fluorescence detection of STR alleles is accomplished with one of the ABI 310 Genetic Analyzers. The ABI 7500 Real-Time PCR system is used to monitor DNA extraction from unusual forensic samples such as dentition. Computer-based GeneMapper software allows students to complete the construction of human DNA Profiles encompassing fifteen STR forensic markers.

Pepperwood Foundation requests support to build a new native plant shadehouse propagation facility to replace the one damaged during the 2017 Tubbs Fire.
Two recent fires have significantly altered the ecological health of the native grasslands at Pepperwood Preserve and destroyed and damaged buildings on our property. Bulldozer fire lines created to stop the Kincade Fire in October 2019 resulted in significant disturbance to 15 miles of oak woodlands and native grasslands. In 2017, the Tubbs Fire burned our barn and shop to the ground, heavily impacting the nearby plant propagation facility. Our rebuild of the barn and shop is under way but requires moving the damaged propagation facility away from the shadow of the new structure. Given the extensive loss of native grasslands to the bulldozer lines, we want to double our native grass plug production numbers from 14,000 to 28,000 plants annually. This increase in production will require doubling the footprint of our propagation facility.
By increasing native plant propagation capacity and plantings this project will improve water quality by reducing erosion as well as improving stream flow by improving water infiltration and soil water holding capacity. Perennial grasses improve soil organic matter and provide better ground cover than non-native annual grasses. These grasses reduce impacts of hard rainfall, slow run-off, and increase water retention, thus reducing potential flooding downstream. Native plants favor healthy wildlife populations and support invertebrates including pollinators.

Arcos Dorados Holdings Inc. is the world's largest McDonald's franchisee, and it operates the brand in Latin America and the Caribbean. It has announced that from 8:30-9:30 p.m. on Saturday, March 25, all its restaurants will turn off their outdoor lights in support of Earth Hour.
Earth Hour was started 10 years ago, by the WWF (World Wildlife Foundation) to increase awareness of climate action. Each year, Earth Hour unites millions of people around the globe in the world's largest grassroots movement. This year will be McDonald's Virgin Islands ninth year participating.
"For Arcos Dorados it is very important to participate in Earth Hour, since it is in line with the company's philosophy. Every day, we try to leave a smaller mark on our planet by managing waste from our restaurants in a responsible way and implementing actions to reduce water and power consumption, and source local ingredients for a more effective supply chain," said Lyana Latorre, senior director of corporate social engagement at Arcos Dorados.
Arcos Dorados has a strong commitment to the planet thereby contributing by carrying out different actions:
- Reuse of condensed water drained from air-conditioning systems of restaurants to irrigate gardens, wash facades and different areas of the premises such as the Drive-Thru. The use of recycled water allows for the reduced consumption of water and energy.
- Installation of Low Oil Volume (LOV) fryers in restaurants. This technology saves up to 40 percent of oil and requires less energy to heat up.
- Green Restaurants: They are built or redesigned to meet LEED (Leadership in Energy and Environmental Design) certification in which rainwater collectors are used for the cleaning of parking lots and flushing toilet bowls. They have a wind-powered installer that allows them to generate electricity using the wind, as well as having LED (Low Emitting Diode) luminaires that use less energy. These restaurants are in Argentina, Brazil, México and Puerto Rico.
- Other measures taken by the Company to protect the planet are: have 100 percent sustainable coffee certified by the Rainforest Alliance in the different markets and sustainable fish certified by the Marine Stewardship Council; as well as working alongside the Global Roundtable of Sustainable Beef to develop the standard and serve meet from sustainable practices.

Our bodies shape our experience of the world, and our bodies influence what we design. How important are the physical differences between people? Can we model the physiological differences and use the models to adapt and personalize designs, user interfaces and artifacts? Within many disciplines Digital Human Models and Standard Observer Models are widely used and have proven to be very useful for modeling users and simulating humans. In this paper, we create personalized digital human models of perception (Individual Observer Models), particularly focused on how humans see. Individual Observer Models capture how our bodies shape our perceptions. Individual Observer Models are useful for adapting and personalizing user interfaces and artifacts to suit individual users' bodies and perceptions. We introduce and demonstrate an Individual Observer Model of human eyesight, which we use to simulate 3600 biologically valid human eyes. An evaluation of the simulated eyes finds that they see eye charts the same as humans. Also demonstrated is the Individual Observer Model successfully making predictions about how easy or hard it is to see visual information and visual designs. The ability to predict and adapt visual information to maximize how effective it is is an important problem in visual design and analytics.
In this talk Professor Aaron Quigley will present a talk for a paper he is presenting at the User Modeling, Adaptation and Personalization (UMAP) conference 2011 on July 12th in Barcelona Spain. This work on Creating Personalized Digital Human Models of Perception for Visual Analytics is the work with and of his former PhD student Dr. Mike Bennett and now postdoctoral fellow in the Department of Psychology in Stanford University.
Professor Aaron Quigley is the Chair of Human Computer Interaction in the School of Computer Science at the University of St Andrews. He is the director of SACHI and his appointment is part of SICSA, the Scottish Informatics and Computer Science Alliance. Aaron's research interests include surface and multi-display computing, human computer interaction, pervasive and ubiquitous computing and information visualisation.

Wasserstein Random Forests and Applications in Heterogeneous Treatment Effects

Organisé par : F. Bechtold, W. Da Silva, A. Fermanian, S. Has, Y. Yu

Lieu : online at _URL_
Sujet : Wasserstein Random Forests and Applications in Heterogeneous Treatment Effects
We propose a new family of Random Forests that can be used to estimate conditional distributions and we highlight its applications on the estimation of Heterogeneous Treatment Effects. We first provide a brief introduction on Breiman's original RF. Then, we present a reformulation using some simple equivalence between empirical variances and Wasserstein distance of empirical measures, which heuristically indicates that Breiman's splitting criterion can be used to obtain conditional distribution estimates in both univariate and multivariate cases. Additionally, respecting the samephilosophy of Breiman's construction, we propose some variant splitting criteria that are more dedicated to the conditional distribution estimation problems. Some preliminary theoretical connections will be revealed, along with various numerical experiments. We expect that the same methodology may also inspire more general supervised learning algorithms such as Boosting and Aggregation, to make them suitable for conditional distribution estimation.

A new numerical scheme is presented for computing strict maximum likelihood (ML) of geometric fitting problems having an implicit constraint. Our approach is orthogonal projection of observations onto a parameterized surface defined by the constraint. Assuming a linearly separable nonlinear constraint, we show that a theoretically global solution can be obtained by iterative Sampson error minimization. Our approach is illustrated by ellipse fitting and fundamental matrix computation. Our method also encompasses optimal correction, computing, e.g., perpendiculars to an ellipse and triangulating stereo images. A detailed discussion is given to technical and practical issues about our approach.

Is it possible to calculate pressure at a point in a pipe, where a solenoid valve shall be placed, given that
 - the pipe carries water (utility supplied, regular water)
 - from an overhead tank (at a certain height from ground)
 - height of tank (i.e. max water column height, although not sure if vertical pipe-length should be added to it?)
 - water is flowing purely under the effect of gravity (and atmospheric pressure)
 - value is installed at a certain height from ground
 - pipe material is PVC
 - pipe diameter is say 1.5inches.

If the fluid is pretty incompressible, the flow rate isn't high and the pipe is wide enough that there aren't surface effects. Then the pressure is simply the height of the head of water above the point multiplied by the density of the fluid.
eg. Water is 0.0361 lbs/cubic inch, so a head of 1ft = 12 inches = 12 * 0.0361 = 0.43 psi
share|cite|improve this answer
The fluid happens to be water. Is it compressible? Pipe is either 1" or 2/3" dia, wonder if it is "wide enough"? Here's a picture. I wonder if the height of the head of water is the length AC, or AB? – icarus74 Jan 16 '12 at 18:44
It's AC, for water in ordinary plumping then just the height is fine. – Martin Beckett Jan 16 '12 at 19:58

A week's work of super hero themed work on commas in a series.
Super Comma Write the Room: A write the room with slips of paper that students collect/paste to their own, and insert the commas. There were 5 little areas around the room where students reached in a bag and pulled one out at random. (For my class, each bag had two different ones in it because cheating in around the room activities was rampant.) (See the thumbnail for bags. I drew super hero logos, but incorporated something about commas on each one. My kids knew I loved super heroes, so they enjoyed it all the more.)
Comma Cut&Paste PPT: Students got a piece of construction paper, each table got a random chunk of these slides. They had to cut them out and paste them in the right order, and paste on little elbow macaronis where the commas go!
The other three Super Comma files are worksheets we worked on (mostly together). I would have them up on the SMART board and have students help me complete them. We made a game of one of them, where I split the class in two, etc., etc.

Speech and singing spread saliva droplets, a phenomenon that has attracted much attention in the current context of the Covid-19 pandemic. Scientists from the CNRS, l'université de Montpellier, and Princeton University* sought to shed light on what takes place during conversations. A first study published in PNAS revealed that the direction and distance of airflow generated when speaking depend on the sounds produced. For example, the accumulation of plosive consonants, such as the "P" in "PaPa," produces a conical airflow that can travel up to 2 metres in 30 seconds. These results also emphasize that the time of exposure during a conversation influences the risk of contamination as much as distance does. A second study published on 2 October in the journal Physical Review Fluids describes the mechanism that produces microscopic droplets during speech: saliva filaments form on the lips for the consonants P and B, for example, and are then extended and fragmented in the form of droplets. This research is being continued with the Metropolitan Opera Orchestra ("MET Orchestra") in New York, as part of a project to identify the safest conditions for continuing this prestigious orchestra's activity.
*The French scientists work at the Centre for Structural Biology (CNRS/Université de Montpellier/Inserm) and the Alexander Grothendieck Institute of Montpellier (CNRS/Université de Montpellier).

in particular "solid agglomerates" of squares, and not e.g. two squares only joined by a vertex.
A simply connected polyomino in the rectangle $[0,n]\times[0,m],$ with vertices of integer coordinates, is precisely determined by its boundary, which may be seen as a closed simple loop in your $n$-by-$m$ square grid graph $\Gamma_{n,m}=(V,E).$ So what you want is precisely the number $N$ of closed simple loops in the graph $\Gamma$. Here by loop I mean, a closed path in $\Gamma$ up to the initial point and up to orientation (that is, a loop is the image of a closed path).
Thus we may write $N=\sum_{k\ge 1} \frac{C(k)}{2k},$ denoting by $C(k)$ the number of simple closed loops of length $k$ (so a simple closed loop of length $k$ is precisely a $k$ ple of distinct vertices $v_1,\dots,v_{k-1}, v_k=v_0$ such that $v_i$ and $v_{i+1}$ are adjacent for $i=1\dots k$). If we denote $c=\sum_k C(k) t ^k $ the GF of the sequence $C(k)$ (a polynomial indeed), we can write $$N:=\int_0^1\frac{c(t)}{2t}dt. $$
Let's then denote $P(u,v,k)$ the number of oriented paths of length $k$ starting at the vertex $v$ and ending at the vertex $u.$ This should be the simplest quantity to compute, for no injectivity is assumed on the paths (it's the $(u,v)$ coefficient in the $k$-power of the adjacency matrix of $\Gamma$ also). Then, I think that one could write $C(k)$ in terms of the $P(u,v,k)$ (via the GF or using the inclusion-exclusion formula. I tried before, with a wrong computation).
So, I'm not sure if this leads somewhere. I'd be glad if somebody could show how to go on along this path.

Imagine electric conductor,copper wire for example,that is fully coated with thin teflon coating and this coated wire is surrounded by air.
The classis high voltage air ionisation happens when the electrons start to escape naked non-insulated conductor and go into the air,its called corona discharge.
My question is,is it possible to cause ionisation of air by high voltage conductor that is fully coated by thin layer of strong insulator like teflon?
I think it my work in following way,near the insulated high voltage conductor,close to its surface there exist strong electric field that can accelerate positive ions or electrons,ofcourse,molecules and atoms of air are neutral,but its a fact that cosmic radiation,radon gas and ultraviolet light causes constant ionisation of air in the enviroment where we live,its very small amount but it exist and these small ionisation events,while invisible happen relatively often.
I think that maybe if one ionisation event happens near the insulated conductor where the electric field is strong,the field might be strong enough at that location to accelerate that electron to such degree it will cause ionisation by colliding with neutral air atom thus causing sort of avalanche where more electrons are ejected,they are accelerated and they ionise more atoms and it repeats and grows exponentialy.
Could all this happen like I described it? Could teflon insulated conductor really cause air ionisation without any current flowing from it into air?
