"Caspase deficiency" has been identified as a cause of tumour development. Tumour growth can occur by a combination of factors, including a mutation in a cell cycle gene which removes the restraints on cell growth, combined with mutations in apoptopic proteins such as caspases that would respond by inducing cell death in abnormally growing cells. Conversely, over-activation of some caspases such as caspase-3 can lead to excessive programmed cell death. This is seen in several neurodegenerative diseases where neural cells are lost, such as Alzheimer's disease. Caspases involved with processing inflammatory signals are also implicated in disease. Insufficient activation of these caspases can increase an organism's susceptibility to infection, as an appropriate immune response may not be activated. The integral role caspases play in cell death and disease has led to research on using caspases as a drug target. For example, inflammatory caspase-1 has been implicated in causing autoimmune diseases; drugs blocking the activation of Caspase-1 have been used to improve the health of patients. Additionally, scientists have used caspases as cancer therapy to kill unwanted cells in tumours.

DRDO as of 11 April 2020 transferred technologies to 30 major companies to manufacture various non-medicine products against the COVID-19 pandemic which includes ventilator, sanitiser, personal protective equipment, face shield and isolation shelter. The technology for the newly developed multiplexed ventilator came from on-board oxygen generation system (OBOGS) developed for HAL Tejas. Private sector players like Raksha Polycoats and Accurate Savan Defence are now producing protective clothing, isolation shelters based on DRDO tech developed for high altitude pulmonary edema (HAPE) bags, submarine escape suit and satellite recovery systems. Hyderabad based jewellary making startup iMake with Modern Manufacturers and Kirat Mechanical Engineering from Chandigarh, Wipro 3D from Bengaluru and Global Healthcare from Delhi are 3D printing visor-based face shields which is an offshoot of the tech developed for high-altitude military parachuting. Setco from Mumbai is producing sealants developed for submarines of Indian Navy at DRDO labs for personal protection equipments.

The radar system for which Alvarez is best known and which has played a major role in aviation, most particularly in the post-war Berlin airlift, was Ground Controlled Approach (GCA). Using Alvarez's dipole antenna to achieve a very high angular resolution, GCA allows ground-based radar operators to watch special precision displays to guide a landing airplane to the runway by transmitting verbal commands to the pilot. The system was simple, direct, and worked well, even with previously untrained pilots. It was so successful that the military continued to use it for many years after the war, and it was still in use in some countries in the 1980s. Alvarez was awarded the National Aeronautic Association's Collier Trophy in 1945 "for his conspicuous and outstanding initiative in the concept and development of the Ground Control Approach system for safe landing of aircraft under all weather and traffic conditions".

Intensive, sustained special education or remedial education programs and behavior therapy early in life can help children acquire self-care, social, and job skills. Available approaches include applied behavior analysis, developmental models, structured teaching, speech and language therapy, social skills therapy, and occupational therapy. Among these approaches, interventions either treat autistic features comprehensively, or focus treatment on a specific area of deficit. Generally, when educating those with autism, specific tactics may be used to effectively relay information to these individuals. Using as much social interaction as possible is key in targeting the inhibition autistic individuals experience concerning person-to-person contact. Additionally, research has shown that employing semantic groupings, which involves assigning words to typical conceptual categories, can be beneficial in fostering learning.

An alternative measure consists of H.E.M. (Healthy blood flow, Eliminate swelling and Mobility). This treatment suggests increasing healthy blood flow to the ankle, including immune cells required for healing. The treatment also suggests improving healthy range of motion, stability and strength in the ankle to aid in a full recovery. Recent research suggests that macrophages (immune cells responsible for muscle repair and growth) are necessary for muscle to grow back to its pre-injured state. The H.E.M. ankle rehab treatment suggests not icing the injury, and instead, following more proactive rehab techniques for recovery: "when ice is applied to a body part for a prolonged period, nearby lymphatic vessels begin to dramatically increase their permeability (lymphatic vessels are ‘dead-end’ tubes which ordinarily help carry excess tissue fluids back into the cardiovascular system). As lymphatic permeability is enhanced, large amounts of fluid begin to pour from the lymphatics ‘in the wrong direction’ (into the injured area), increasing the amount of local swelling and pressure and potentially contributing to greater pain."

The Reformed faith took different shapes in different parts of Europe. In France, groups of Christians influenced by Protestant writers (who became known as Huguenots) formed secretly and started underground churches and informal Bible reading groups. Ministers were dispatched from Geneva and other Swiss cities along with a massive outpouring of propaganda which assured the Reformed nature of the French Reformation. Calvin also aided in the creation of the French Confession of Faith in 1559. The French Protestants did gain some notable allies, including Renée of France, daughter of King Louis XII, as well as Queen Jeanne III of Navarre and her son, Henry (who later converted to Roman Catholicism upon ascending the throne of France). The newly formed churches developed a presbyterial system of church government with national and regional synods. The network of synods proved helpful in mobilizing Reformed Christians to military resistance during the French Wars of Religion between Protestants and Catholics from 1562 to 1598. Calvin's successor in Geneva Theodore Beza also argued in his "Right of Magistrates" that armed resistance against tyrannical rulers was justified, which contradicted Calvin's earlier insistence on civil obedience and emboldened Huguenots to fight. The wars of religion left the French Reformed church between one-third and one-half the size of that at which it began with limited freedom to practice their religion, though intermittent conflicts continued. Unlike in the Genevan model and many other early Reformed churches, the Reformed Church in France remained relatively independent of the state.

The DGT technique was developed in 1994 by Hao Zhang and William Davison at the Lancaster Environment Centre of Lancaster University in the United Kingdom. The technique was first used to detect metal cations in marine environments using Chelex 100 as the binding agent. Further characterisation of DGT, including the results of field deployments in the Menai Strait and the North Atlantic Ocean, was published in 1995. The technique was first tested in soils in 1998, with results demonstrating that kinetics of dissociation of labile species in the porewater (soil solution) could be determined via DGT. Since then, the DGT technique has been modified and expanded to include a significant number of elements and compounds, including cationic metals, nitrate, phosphate and other oxyanions (V, Cr, As, Se, Mo, Sb, W), antibiotics, bisphenols, and nanoparticles, and has even been modified for the geochemical exploration of gold. DGT has also been developed and calibrated for the measure of radionuclides, including for the analysis of actinides such as U, Pu, Am and Cm, both in the environment and even in cooling pools for spent nuclear fuel rods.

Hydrogen fuel enhancement from electrolysis (utilizing automotive alternators) has been promoted for use with gasoline-powered and diesel trucks, although electrolysis-based designs have repeatedly failed efficiency tests and contradict widely accepted laws of thermodynamics (i.e. conservation of energy). Proponents, who sell the units (often called "HHO devices"), claim that the dynamics are often misconstrued, and due to the chemical properties of the resulting mixture, it is possible to gain efficiency increases in a manner that does not violate any scientific laws. Many tests by consumer watch groups have shown negative results. This technique may seem appealing to some at first because it is easy to overlook energy losses in the system as a whole. Those unfamiliar with electrodynamics may not realize that the electrolytic cell drains current from a car's electrical system causing an increase in mechanical resistance in the alternator that will always result in a net power reduction.

In 1943, production of the V-2 rocket began in Germany. It had an operational range of and carried a warhead, with an amatol explosive charge. It normally achieved an operational maximum altitude of around , but could achieve if launched vertically. The vehicle was similar to most modern rockets, with turbopumps, inertial guidance and many other features. Thousands were fired at various Allied nations, mainly Belgium, as well as England and France. While they could not be intercepted, their guidance system design and single conventional warhead meant that they were insufficiently accurate against military targets. A total of 2,754 people in England were killed, and 6,523 were wounded before the launch campaign was ended. There were also 20,000 deaths of slave labour during the construction of V-2s. While it did not significantly affect the course of the war, the V-2 provided a lethal demonstration of the potential for guided rockets as weapons.

As a combination of armoured gunship and troop transport, the Mi-24 has no direct NATO counterpart. While the UH-1 ("Huey") helicopters were used by the US in the Vietnam War either to ferry troops, or as gunships, they were not able to do both at the same time. Converting a UH-1 into a gunship meant stripping the entire passenger area to accommodate extra fuel and ammunition, and removing its troop transport capability. The Mi-24 was designed to do both, and this was greatly exploited by airborne units of the Soviet Army during the 1980–89 Soviet–Afghan War. The closest Western equivalent was the American Sikorsky S-67 Blackhawk, which used many of the same design principles and was also built as a high-speed, high-agility attack helicopter with limited troop transport capability using many components from the existing Sikorsky S-61. The S-67, however, was never adopted for service. Other Western equivalents are the Romanian Army's IAR 330, which is a licence-built armed version of the Aérospatiale SA 330 Puma, and the MH-60 Direct Action Penetrator, a special purpose armed variant of the Sikorsky UH-60 Black Hawk.

During his decline, the program at Wesleyan continue through his associates. His collaborator and successor, Frances Benedict continued his work and helped establish a Nutrition Laboratory in Boston with funding from the Carnegie Corporation. Initially, the funding was meant construct a new laboratory for Atwater and fund his continued work; however, with the realization that he would not be returning, the funds were transferred to the Boston laboratory project. Benedict continued Atwater's work and used the respiration calorimeter to further measure metabolism and other bodily processes. Benedict studied the varying metabolism rates of infants born in two hospitals in Massachusetts, athletes, students, vegetarians, Mayans living in the Yucatán, and normal adults. He even developed a calorimeter large enough to hold twelve girl scouts for an extended period of time. His biggest improvement was the invention of portable field respiration calorimeters. In 1919, Francis Benedict published a metabolic standards report with extensive tables based on age, sex, height, and weight.

By analogy with other aircraft programmes, a third direction in the efforts to acquire foreign technology may have involved illicit action along the lines of the reverse engineering of the Tu-4 from the B-29 and the copying of the Rolls-Royce Nene jet engine as the Klimov VK-1. Oblique reference to this comes in an account of the An-124 by the then-powerplant head of the Antonov bureau, V. G. Anisyenko: "The MAP leadership wanted to have a uniform large engine also capable of civil aviation applications, such as the Il-86. The most suitable analogue from this viewpoint was considered to be the Rolls-Royce RB.211-22. To purchase it, in 1976 a MAP procurement party went to Great Britain, headed by engine construction deputy minister Dondukov ... Our ultimate task was to copy the RB.211-22, for which purpose we had to buy not fewer than eight examples ... The English ... would only sell us the engine in quantities ... to power no fewer than 100 aircraft. As a result, we did not get a sample ... "

Despite the practice emerging over the past few decades, the delivery of emergency medicine has significantly increased and evolved across diverse settings related to cost, provider availability and overall usage. Before the Affordable Care Act (ACA), emergency medicine was leveraged primarily by "uninsured or underinsured patients, women, children, and minorities, all of whom frequently face barriers to accessing primary care". While this still exists today, as mentioned above, it is critical to consider the location in which care is delivered to understand the population and system challenges related to overutilization and high cost. In rural communities where provider and ambulatory facility shortages exist, a primary care physician (PCP) in the ED with general knowledge is likely to be the only source of health care for a population, as specialists and other health resources are generally unavailable due to lack of funding and desire to serve in these areas. As a result, the incidence of complex co-morbidities not managed by the appropriate provider results in worse health outcomes and eventually costlier care that extends beyond rural communities. Though typically quite separated, PCPs in rural areas must partner with larger health systems to comprehensively address the complex needs of their community, improve population health, and implement strategies such as telemedicine to improve health outcomes and reduce ED utilization for preventable illnesses. (See: Rural health.)

An often overlooked dimension in the history of science, the patronage system and the realities that existed within such a system played an important role in the lives of many of science's icons and heroes. The history of astronomy in particular is filled with examples demonstrating the relationship between patron and client, including that of Galileo Galilei and his ties to the Medici family. Many historians have begun to examine the importance of examining scientific history through this relatively forgotten lens. Dr. Robert Smith, in an article examining patronage in the early history of NASA, begins with the assertion that “the history of space astronomy is usually written from the perspective of the remarkable scientific findings garnered by space astronomers and the ways these findings have enriched and guided new views of the universe.” But, as Barker and Goldstein ensure, “following the groundbreaking work of Robert Westman and Richard S. Westfall, historians of astronomy and historians of science in general have come to appreciate the importance of patronage in understanding the development of science during the sixteenth and seventeenth centuries.” As crucial as the many developments and findings of science's heroes are to the historiography of science, many historians, like Nicholas Jardine, Mario Biagioli, Richard Westfall and others, have sought to bring to light the issues of patronage within this discourse, and their works have looked to enrich the understandings of many of science's heroes, including Galileo Galilei, Johannes Kepler, and Tycho Brahe amongst others. Patronage cannot provide the lone solution to understanding the social history of the Scientific Revolution, as some figures in the movement “were not sustained by patronage, and it is not yet clear how many were so supported.” Despite this, patronage “was perhaps the most pervasive institution of preindustrial society.”

Enzymes have been postulated to use quantum tunneling in order to transfer electrons from one place to another in electron transport chains. It is possible that protein quaternary architectures may have adapted to enable sustained quantum entanglement and coherence, which are two of the limiting factors for quantum tunneling in biological entities. These architectures might account for a greater percentage of quantum energy transfer, which occurs through electron transport and proton tunneling (usually in the form of hydrogen ions, H). Tunneling refers to the ability of a subatomic particle to travel through potential energy barriers. This ability is due, in part, to the principle of complementarity, which holds that certain substances have pairs of properties that cannot be measured separately without changing the outcome of measurement. Particles, such as electrons and protons, have wave-particle duality; they can pass through energy barriers due to their wave characteristics without violating the laws of physics. In order to quantify how quantum tunneling is used in many enzymatic activities, many biophysicists utilize the observation of hydrogen ions. When hydrogen ions are transferred, this is seen as a staple in an organelle's primary energy processing network; in other words, quantum effects are most usually at work in proton distribution sites at distances on the order of an angstrom (1 Å). In physics, a semiclassical (SC) approach is most useful in defining this process because of the transfer from quantum elements (e.g. particles) to macroscopic phenomena (e.g. biochemicals). Aside from hydrogen tunneling, studies also show that electron transfer between redox centers through quantum tunneling plays an important role in enzymatic activity of photosynthesis and cellular respiration (see also Mitochondria section below). For example, electron tunneling on the order of 15–30 Å contributes to redox reactions in cellular respiration enzymes, such as complexes I, III, and IV in mitochondria. Without quantum tunneling, organisms would not be able to convert energy quickly enough to sustain growth. Quantum tunneling actually acts as a shortcut for particle transfer; according to quantum mathematics, a particle's jump from in front of a barrier to the other side of a barrier occurs faster than if the barrier had never been there in the first place. (For more on the technicality of this, see Hartman effect.)

In 2012, other small molecules (selective cytotoxic inhibitors of human pluripotent stem cells – hPSCs) were identified that prevented human pluripotent stem cells from forming teratomas in mice. The most potent and selective compound of them (PluriSIn #1) inhibits stearoyl-coA desaturase (the key enzyme in oleic acid biosynthesis), which finally results in apoptosis. With the help of this molecule, the undifferentiated cells can be selectively removed from culture. An efficient strategy to selectively eliminate pluripotent cells with teratoma potential is targeting pluripotent stem cell-specific antiapoptotic factor(s) (i.e., survivin or Bcl10). A single treatment with chemical survivin inhibitors (e.g., quercetin or YM155) can induce selective and complete cell death of undifferentiated hPSCs and is claimed to be sufficient to prevent teratoma formation after transplantation. However, it is unlikely that any kind of preliminary clearance is able to secure the replanting of iPSCs or ESCs. After the selective removal of pluripotent cells, they re-emerge quickly by reverting differentiated cells into stem cells, which leads to tumors. This may be due to the disorder of let-7 regulation of its target Nr6a1 (also known as Germ cell nuclear factor - GCNF), an embryonic transcriptional repressor of pluripotency genes that regulates gene expression in adult fibroblasts following micro-RNA miRNA loss.

The Australian withdrawal effectively commenced in November 1970. As a consequence of the overall allied strategy of Vietnamization and with the Australian government keen to reduce its own commitment to the war, 8 RAR was not replaced at the end of its tour of duty. 1 ATF was again reduced to just two infantry battalions, albeit with significant armour, artillery and aviation support remaining. Australian combat forces were further reduced during 1971 as part of a phased withdrawal, and 1 ATF ceased operations in October. Meanwhile, the advisors remained to train South Vietnamese troops until withdrawn on 18 December 1972 by the newly elected Labor government of Gough Whitlam. The last Australian forces were finally withdrawn in 1973. The Vietnam War was Australia's longest and most controversial war and although initially enjoying broad support, as the nation's military involvement increased a vocal anti-war movement developed. More than 50,000 Australians served in Vietnam; 519 were killed and 2,398 were wounded. Four were awarded the Victoria Cross.

After publicly defending forty nine theses in the Palazzo Pubblico, Laura Bassi was awarded a doctorate of Philosophy in 1732 at the University of Bologna. Thus, Bassi became the second woman in the world to earn a philosophy doctorate after Elena Cornaro Piscopia in 1678, 54 years prior. She subsequently defended twelve additional theses at the Archiginnasio, the main building of the University of Bologna which allowed her to petition for a teaching position at the university. In 1732 the university granted Bassi's professorship in philosophy, making her a member of the Academy of the Sciences and the first woman to earn a professorship in physics at a university in Europe But the university held the value that women were to lead a private life and from 1746 to 1777 she gave only one formal dissertation per year ranging in topic from the problem of gravity to electricity. Because she could not lecture publicly at the university regularly, she began conducting private lessons and experiments from home in the year of 1749. However, due to her increase in responsibilities and public appearances on behalf of the university, Bassi was able to petition for regular pay increases, which in turn was used to pay for her advanced equipment. Bassi earned the highest salary paid by the University of Bologna of 1,200 lire. In 1776, at the age of 65, she was appointed to the chair in experimental physics by the Bologna Institute of Sciences with her husband as a teaching assistant.

Robertson continued to work on dairy-related research and wider theoretical studies. He did much to introduce widespread use of artificial insemination in dairy cattle, and worked for many years on estimating genetic effects that influence quantitative traits, and he developed what became known as the "secondary theorem of natural selection." He held the post of Deputy chief scientific officerof his Unit, and kept away from administrative duties. Hill recalled that Robertson "remained informal, approachable, and 'Alan' to all. His influence was through his papers, as a scientific referee, by personal contact (particularly in his famous morning coffee group), as a conference speaker and organizer, and as an example of efficient (if not organized) hard work." His doctoral students included William G. Hill, Trudy Mackay and Paul M. Sharp.

Many of them quoted obsolete geological writings. Among the most prominent, Granville Penn argued in 1822 that "mineral geology" rejected revelation, while true "Mosaical geology" showed that God had created primitive rock formations directly, in correspondence with the laws which God then made to produce subsequent effects. A first revolution on the third day of creation deepened the oceans so water rushed in, and in the Deluge 1,656 years afterwards a second revolution sank land areas and raised the sea bed to cause a swirling flood which moved soil and fossil remains into stratified layers, after which God created new vegetation. As Genesis appeared to show that the rivers of Eden had survived this catastrophe, he argued that the verses concerned were an added "parenthesis" which should be disregarded. In 1837 George Fairholme expressed disappointment about disappearing belief in the deluge, and about Sedgwick and Buckland recanting diluvialism, while putting forward his own "New and Conclusive Physical Demonstrations" which ignored geological findings to claim that strata had been deposited in a quick continuous process while still moist.

The commonly used deep ultraviolet excimer lasers in lithography systems are the krypton fluoride (KrF) laser at 248 nm wavelength and the argon fluoride laser (ArF) at 193 nm wavelength. The primary manufacturers of excimer laser light sources in the 1980s were Lambda Physik (now part of Coherent, Inc.) and Lumonics. Since the mid-1990s Cymer Inc. has become the dominant supplier of excimer laser sources to the lithography equipment manufacturers, with Gigaphoton Inc. as their closest rival. Generally, an excimer laser is designed to operate with a specific gas mixture; therefore, changing wavelength is not a trivial matter, as the method of generating the new wavelength is completely different, and the absorption characteristics of materials change. For example, air begins to absorb significantly around the 193 nm wavelength; moving to sub-193 nm wavelengths would require installing vacuum pump and purge equipment on the lithography tools (a significant challenge). An inert gas atmosphere can sometimes be used as a substitute for a vacuum, to avoid the need for hard plumbing. Furthermore, insulating materials such as silicon dioxide, when exposed to photons with energy greater than the band gap, release free electrons and holes which subsequently cause adverse charging.

Webern insisted on lyricism, nuance, rubato, sensitivity, and both emotional and intellectual understanding in performance of music; this is evidenced by anecdotes, correspondence, extant recordings of Schubert's "Deutsche Tänze" (arr. Webern) and Berg's Violin Concerto under his direction, many such detailed markings in his scores (including a specially marked score of the Piano Variations), and finally by his compositional process as both publicly stated and later revealed in the musical and extramusical metaphors and associations everywhere throughout his sketches. As both a composer and conductor, he was one of many (e.g., Wilhelm Furtwängler, Dimitri Mitropoulos, Hermann Scherchen) in a contemporaneous tradition of conscientiously and non-literally handling notated musical figures, phrases, and even entire scores so as to maximize expressivity in performance and to cultivate audience engagement and understanding. Felix Galimir, of the Galimir Quartet, told "The New York Times" in 1981: "Berg asked for enormous correctness in the performance of his music. But the moment this was achieved, he asked for a very Romanticized treatment. Webern, you know, was also terribly Romantic—as a person, and when he conducted. Everything was almost over-sentimentalized. It was entirely different from what we have been led to believe today. His music should be played very freely, very emotionally."

The cladding materials, in this case having the highly combustible Polyethylene (PE) core, were implicated as the principal cause of the rapid spread of flame in the 2017 Grenfell Tower fire in London. It has also been involved in high-rise building fires in Melbourne, Australia; France; the United Arab Emirates; South Korea; and the United States. Fire-rated cores (typically designated as "FR" by the manufacturers) are a safer alternative as they have a maximum of 30% Polyethylene Content, and will self-extinguish in the absence of heat/ventilation. As with any building product, fitness for use is dependent on multiple other products and methods. In the case of ACP, building codes in USA have many requirements related to the wall assembly depending on the materials used and the building type. When these building codes are followed, the FR core products are safe. Note that the term ACP does not apply to sandwich panels with Mineral Wool cores, which fall under the category of Insulated Metal Panels (IMP).

It was not until the 1970s when fully programmable computers appeared that could fit entirely on top of a desk. 1970 saw the introduction of the Datapoint 2200, a "smart" computer terminal complete with keyboard and monitor, was designed to connect with a mainframe computer but that didn't stop owners from using its built-in computational abilities as a stand-alone desktop computer. The HP 9800 series, which started out as programmable calculators in 1971 but was programmable in BASIC by 1972, used a smaller version of a minicomputer design based on ROM memory and had small one-line LED alphanumeric displays and displayed graphics with a plotter. The Wang 2200 of 1973 had a full-size cathode-ray tube (CRT) and cassette tape storage. The IBM 5100 in 1975 had a small CRT display and could be programmed in BASIC and APL. These were generally expensive specialized computers sold for business or scientific uses.

To be able to create an image that will not be distorted or out of place, the displays and sensors must be calibrated. The calibration process depends on the motion capture technology being used. Optical or Inertial-acoustic systems only requires to configure the zero and the axes used by the tracking system. Calibration of electromagnetic sensors (like the ones used in the first cave) is more complex. In this case a person will put on the special glasses needed to see the images in 3D. The projectors then fill the CAVE with many one-inch boxes set one foot apart. The person then takes an instrument called an "ultrasonic measurement device" which has a cursor in the middle of it, and positions the device so that the cursor is visually in line with the projected box. This process can go on until almost 400 different blocks are measured. Each time the cursor is placed inside a block, a computer program records the location of that block and sends the location to another computer. If the points are calibrated accurately, there should be no distortion in the images that are projected in the CAVE. This also allows the CAVE to correctly identify where the user is located and can precisely track their movements, allowing the projectors to display images based on where the person is inside the CAVE.

As World War II drew to a close, it became apparent to University administration that a new masterplan was necessary for transitioning the University for the post-war era. Key objectives of this new plan were to absorb the exploding student population as well as update the current campus. Accordingly, President Rufus B. von KleinSmid commissioned architects Henry C. Burge, Arthur B. Gallion, and C. Raimond Johnson to design a new masterplan for geographic expansion and campus construction. The philosophy of this plan greatly diverged from that of the Pinkerson plan. Whereas the previous plan placed great rigidity on the architectural styles of the buildings as well as how buildings would be apportioned between departments, this new masterplan placed emphasis on flexibility, choosing not to specify any architectural style to be used or how departments were to share spaces. Rather, it offered more generalized recommendations on where certain facilities should be located and recommended an adherence to the red brick aesthetic established per the Pinkerson plan. It was through this plan that the clear boundaries of the campus began to become realized: Exposition Boulevard, Figueroa Street, Jefferson Boulevard, and McClintock Avenue. Additionally, this plan proposed using portions of the land within these campus boundaries for surface parking lots as well as closed the internal campus street network to traffic. Whereas the previous plan was automobile-oriented, this new one placed emphasis on the pedestrian. Traffic through Trousdale Parkway was formally closed in 1953.

Consequently, paleontologists must usually rely on stratigraphy to date fossils. Stratigraphy is the science of deciphering the "layer-cake" that is the sedimentary record, and has been compared to a jigsaw puzzle. Rocks normally form relatively horizontal layers, with each layer younger than the one underneath it. If a fossil is found between two layers whose ages are known, the fossil's age must lie between the two known ages. Because rock sequences are not continuous, but may be broken up by faults or periods of erosion, it is very difficult to match up rock beds that are not directly next to one another. However, fossils of species that survived for a relatively short time can be used to link up isolated rocks: this technique is called "biostratigraphy". For instance, the conodont "Eoplacognathus pseudoplanus" has a short range in the Middle Ordovician period. If rocks of unknown age are found to have traces of "E. pseudoplanus", they must have a mid-Ordovician age. Such index fossils must be distinctive, be globally distributed and have a short time range to be useful. However, misleading results are produced if the index fossils turn out to have longer fossil ranges than first thought. Stratigraphy and biostratigraphy can in general provide only relative dating ("A" was before "B"), which is often sufficient for studying evolution. However, this is difficult for some time periods, because of the problems involved in matching up rocks of the same age across different continents.

The aircraft has a wide blended wing body fuselage with two widely spaced engines and has all-moving horizontal and vertical stabilisers, with the vertical stabilisers canted for stealth; the trapezoid wings have leading edge flaps, ailerons, and flaperons. The aircraft incorporates thrust vectoring and large leading edge root extensions that shift the aerodynamic center forward, increasing static instability and maneuverability. These extensions have adjustable leading–edge vortex controllers (LEVCONs) designed to control the generated vortices and can provide trim and improve high angle of attack behaviour, including a quick stall recovery if the thrust vectoring system fails. To air-brake, the ailerons deflect up while the flaperons deflect down and the vertical stabilisers toe inward to increase drag. Although the majority of the structural materials are alloys with 40.5–44.5% aluminum alloys and 18.6% titanium alloys, the aircraft makes extensive use of composites, with the material comprising 22–26% of the structural weight and approximately 70% of the outer surface.

Poliovirus is an enterovirus. Infection occurs via the fecal–oral route, meaning that one ingests the virus and viral replication occurs in the gastrointestinal tract. Virus is shed in the feces of infected individuals. In 95% of cases only a primary, transient presence of viremia (virus in the bloodstream) occurs, and the poliovirus infection is asymptomatic. In about 5% of cases, the virus spreads and replicates in other sites such as brown fat, reticuloendothelial tissue, and muscle. The sustained viral replication causes secondary viremia and leads to the development of minor symptoms such as fever, headache, and sore throat. Paralytic poliomyelitis occurs in less than 1% of poliovirus infections. Paralytic disease occurs when the virus enters the central nervous system (CNS) and replicates in motor neurons within the spinal cord, brain stem, or motor cortex, resulting in the selective destruction of motor neurons leading to temporary or permanent paralysis. This is a very rare event in babies, who still have anti-poliovirus antibodies acquired from their mothers. In rare cases, paralytic poliomyelitis leads to respiratory arrest and death. In cases of paralytic disease, muscle pain and spasms are frequently observed prior to onset of weakness and paralysis. Paralysis typically persists from days to weeks prior to recovery.

The mechanism proposed by Hausinger and Karplus attempts to revise some of the issues apparent in the Blakely and Zerner pathway, and focuses on the positions of the side chains making up the urea-binding pocket. From the crystal structures from "K. aerogenes" urease, it was argued that the general base used in the Blakely mechanism, His, was too far away from the Ni2-bound water to deprotonate in order to form the attacking hydroxide moiety. In addition, the general acidic ligand required to protonate the urea nitrogen was not identified. Hausinger and Karplus suggests a reverse protonation scheme, where a protonated form of the His ligand plays the role of the general acid and the Ni2-bound water is already in the deprotonated state. The mechanism follows the same path, with the general base omitted (as there is no more need for it) and His donating its proton to form the ammonia molecule, which is then released from the enzyme. While the majority of the His ligands and bound water will not be in their active forms (protonated and deprotonated, respectively,) it was calculated that approximately 0.3% of total urease enzyme would be active at any one time. While logically, this would imply that the enzyme is not very efficient, contrary to established knowledge, usage of the reverse protonation scheme provides an advantage in increased reactivity for the active form, balancing out the disadvantage. Placing the His ligand as an essential component in the mechanism also takes into account the mobile flap region of the enzyme. As this histidine ligand is part of the mobile flap, binding of the urea substrate for catalysis closes this flap over the active site and with the addition of the hydrogen bonding pattern to urea from other ligands in the pocket, speaks to the selectivity of the urease enzyme for urea.

Almost all engineering drawings (except perhaps reference-only views or initial sketches) communicate not only geometry (shape and location) but also dimensions and tolerances for those characteristics. Several systems of dimensioning and tolerancing have evolved. The simplest dimensioning system just specifies distances between points (such as an object's length or width, or hole center locations). Since the advent of well-developed interchangeable manufacture, these distances have been accompanied by tolerances of the plus-or-minus or min-and-max-limit types. "Coordinate dimensioning" involves defining all points, lines, planes, and profiles in terms of Cartesian coordinates, with a common origin. Coordinate dimensioning was the sole best option until the post-World War II era saw the development of geometric dimensioning and tolerancing (GD&T), which departs from the limitations of coordinate dimensioning (e.g., rectangular-only tolerance zones, tolerance stacking) to allow the most logical tolerancing of both geometry and dimensions (that is, both form [shapes/locations] and sizes).

With the increasing likelihood of a contested electromagnetic spectrum (EMS) in an era of great power competition, the idea of a "BACN-mesh" was proposed by Professor Jahara Matisek (and former E-11 BACN pilot) at the US Air Force Academy, as a way of pursuing new multi-domain war-fighting options against near-peers. Specifically, Prof. Matisek suggests that smart node pods (i.e. a BACN-light payloads affixed to aircraft with hardpoints), could provided layered BACN “bridging” connections and TDL services to war-fighters in an EMS-contested battlespace, without deploying a specific BACN aircraft. For example, in the Pacific – where infrastructure is limited – a “BACN-mesh” concept could be employed to create real-time battlespace pictures, proving useful when a near-peer adversary attempts localized jamming across the EMS. A "BACN-mesh" concept, if properly employed with numerous smart node equipped aircraft, would "create a complex, impregnable, and mutually reinforcing communication network with multiple relay nodes."

The publishing section was established in 1948 to invigorate the organization's publishing activities. S. S. Shleymovich was the first to head it. In 1968, as the amount of publications by the USSR AS Karelian Branch grew substantially, the publishing section was transformed into the Editorial and Publishing Department (EPD). In 1971 the EPD became authorized to publish the journal of proceedings of the Karelian Branch. In 1973 the instant printing shop was set up to publish collected volumes and monographic books without having to engage external book publishers. The number of limited circulation editions (express publication of research results, pre-prints of conference papers and abstracts, etc.) increased remarkably. In 1992 the Editorial and Publishing Department and the instant printing shop were merged into one unit to promote the efficiency of their operation. The time period from manuscript submission to final product became much shorter, the entire publishing process was optimized. A new phase in EPD development started in the 1990s with the onset of the computer era. Technical facilities of the editorial group were updated. Layout and design were computerized. Through renovation of the publishing process the quality of the printed products was notably improved, their volumes enlarged and the preparation and production cycle shortened. The EPD now implements the entire book publishing cycle. The principal concern for the EPD is to produce its editions so that they meet all modern standards.

During the SAR development of rivaroxaban, researchers realized that adding a 5-chlorothiophene-2-carboxamide group to the oxazolidonine core could increase the potency by 200 fold, which had previously been too weak for medical use. In addition to this discovery, a clear preference for the (S)-configuration was confirmed. This compound had a promising pharmacokinetical profile and did not contain a highly basic amidine group, but that had previously been considered important for the interaction with the S1 pocket. These findings lead to extensive SAR (structure-activity relationship) researches. During the SAR testing, R1 was defined as the most important group for potency. Pyrrolidinone was the first R1 functional group to significantly increase the potency but further researches revealed even higher potency with a morpholinone group instead. Groups R2 and R3 had hydrogen or fluorine attached and it was quickly assessed that having hydrogen resulted in highest potency. Groups R2 and R3 were then substituted for various groups, which were all less potent than the hydrogen, so hydrogen was the final result. As the chlorothiophene moiety had an inadequate water solubility, substituting it with another group was attempted but was unsuccessful. The chlorothiophene moiety binds to Tyr-228 at the bottom of the S1 pocket, making it a key factor regarding binding to FXa. Rivaroxaban has both high affinity and good bioavailability.

Franz Aepinus is credited as the first to conceive of the view of the reciprocal relationship of electricity and magnetism. In his work "Tentamen Theoria Electricitatis et Magnetism", published in Saint Petersburg in 1759, he gives the following amplification of Franklin's theory, which in some of its features is measurably in accord with present-day views: "The particles of the electric fluid repel each other, attract and are attracted by the particles of all bodies with a force that decreases in proportion as the distance increases; the electric fluid exists in the pores of bodies; it moves unobstructedly through non-electric (conductors), but moves with difficulty in insulators; the manifestations of electricity are due to the unequal distribution of the fluid in a body, or to the approach of bodies unequally charged with the fluid." Aepinus formulated a corresponding theory of magnetism excepting that, in the case of magnetic phenomena, the fluids only acted on the particles of iron. He also made numerous electrical experiments apparently showing that, in order to manifest electrical effects, tourmaline must be heated to between 37.5 °C and 100 °C. In fact, tourmaline remains unelectrified when its temperature is uniform, but manifests electrical properties when its temperature is rising or falling. Crystals that manifest electrical properties in this way are termed pyroelectric; along with tourmaline, these include sulphate of quinine and quartz.

To account for this phenomenon, Galvani assumed that electricity of opposite kinds existed in the nerves and muscles of the frog, the muscles and nerves constituting the charged coatings of a Leyden jar. Galvani published the results of his discoveries, together with his hypothesis, which engrossed the attention of the physicists of that time. The most prominent of these was Volta, professor of physics at Pavia, who contended that the results observed by Galvani were the result of the two metals, copper and iron, acting as electromotors, and that the muscles of the frog played the part of a conductor, completing the circuit. This precipitated a long discussion between the adherents of the conflicting views. One group agreed with Volta that the electric current was the result of an electromotive force of contact at the two metals; the other adopted a modification of Galvani's view and asserted that the current was the result of a chemical affinity between the metals and the acids in the pile. Michael Faraday wrote in the preface to his "Experimental Researches", relative to the question of whether metallic contact is productive of a part of the electricity of the voltaic pile: "I see no reason as yet to alter the opinion I have given; ... but the point itself is of such great importance that I intend at the first opportunity renewing the inquiry, and, if I can, rendering the proofs either on the one side or the other, undeniable to all."

Mostov received a PhD in Biological Science from the Rockefeller University in the laboratory of Nobel laureate Günter Blobel in 1983, and an MD from Weill Cornell Medicine in 1984. He was a Whitehead Fellow at the Whitehead Institute of MIT from 1984 to 1989. In 1989, Mostov joined the faculty of the University of California, San Francisco, School of Medicine, where he is currently Professor. Mostov and colleagues discovered and sequenced the Polymeric Immunoglobulin Receptor (pIgR) and proposed the generally accepted model of its pathway and function. Neil E. Simister and Mostov cloned and sequenced the Neonatal Fc Receptor (FcRn). Mostov and colleagues showed how signals in the pIgR direct its polarized trafficking and how polarized MDCK epithelial cells form three-dimensional structures with lumens and tubules. Mostov and colleagues further found how simple rules cause different branching patterns in kidney as compared to other branching tubular organs

DHPA was first described in the literature in 1958 and was patented in 1960. It was developed in combination with estradiol enantate as a long-lasting combined injectable contraceptive under the tentative brand names Deladroxate and Droxone by Squibb and was studied in women starting in 1964. Development was discontinued by Squibb in the United States in the late 1960s due to concerns of toxicological findings in animals, including mammary gland tumors in beagle dogs and pituitary hyperplasia in rats, as well as possible accumulation of estradiol enantate in the body with continued use. Subsequent research has shed doubt that these animal findings are applicable to humans and that the dosages required for contraception would pose any risks. Although the medication was not marketed in the United States, its development was continued elsewhere and it went on to be introduced and widely used in Latin America and Spain. A standalone version of DHPA was introduced in Italy in 1982 under the brand names Neolutin Depo and Neolutin Depositum. This single-drug formulation has since been discontinued. DHPA remains available in Latin America, but is no longer marketed in Europe.

The third root of group theory was number theory. Leonhard Euler considered algebraic operations on numbers modulo an integer—modular arithmetic—in his generalization of Fermat's little theorem. These investigations were taken much further by Carl Friedrich Gauss, who considered the structure of multiplicative groups of residues mod n and established many properties of cyclic and more general abelian groups that arise in this way. In his investigations of composition of binary quadratic forms, Gauss explicitly stated the associative law for the composition of forms. In 1870, Leopold Kronecker gave a definition of an abelian group in the context of ideal class groups of a number field, generalizing Gauss's work. Ernst Kummer's attempts to prove Fermat's Last Theorem resulted in work introducing groups describing factorization into prime numbers. In 1882, Heinrich M. Weber realized the connection between permutation groups and abelian groups and gave a definition that included a two-sided cancellation property but omitted the existence of the inverse element, which was sufficient in his context (finite groups).

By early 1926, Pedersen had designed and built a prototype rifle. He had researched Army tactics and operational concepts, and had engineered the tooling for parts manufacture as an integral part of engineering the gun parts themselves. Such an application of sound research and development made a very strong impression on Army personnel when the rifle was presented for inspection and testing. The rifle was a solid, well-finished weapon, 44 inches (112 cm) long, weighing slightly over 8 pounds (3.6 kg). It utilized a disposable ten-round "en bloc" clip, a system favored at the time. Pedersen's rifle utilized a sophisticated up-breaking toggle-joint system like the Parabellum P.08 but improved by utilizing delayed blowback. This system was simple and free of both the fragility and severe kick of recoil operation, and the weight and complexity of gas operation (as in the Browning Automatic Rifle). To ease extraction, cartridge cases were coated in mineral wax. This left a thin film that was “hard, and durable, and was not sticky,”. The waxed cases solved the issue of difficult extraction, but hindered acceptance of the Pedersen rifle because officials feared that the wax would attract dirt and cause operating failures.

Eustrongylidosis is a parasitic disease that mainly affects wading birds worldwide; however, the parasite's complex, indirect lifecycle involves other species, such as aquatic worms and fish. Moreover, this disease is zoonotic, which means the parasite can transmit disease from animals to humans. Eustrongylidosis is named after the causative agent "Eustrongylides", and typically occurs in eutrophicated waters where concentrations of nutrients and minerals are high enough to provide ideal conditions for the parasite to thrive and persist. Because eutrophication has become a common issue due to agricultural runoff and urban development, cases of eustrongylidosis are becoming prevalent and hard to control. Eustrongylidosis can be diagnosed before or after death by observing behavior and clinical signs, and performing fecal flotations and necropsies. Methods to control it include preventing eutrophication and providing hosts with uninfected food sources in aquaculture farms. Parasites are known to be indicators of environmental health and stability, so should be studied further to better understand the parasite's lifecycle and how it affects predator-prey interactions and improve conservation efforts.

The economics syllabus at the University of Sydney during the 1960s had been dominated by a mix of microeconomics, macroeconomics (influenced by John Maynard Keynes), and the study of Australian and international economic institutions. Colin Simkin and Warren Hogan were appointed as professors to the Sydney University economics department in 1968–1969 to 'modernise' the program, making the courses more neoclassical theory-heavy, and mathematical. Both academics had been chosen by the Vice-Chancellor Professor Bruce Williams who had previously been Professor of Economics in the UK at Manchester University. They would become the core figures pushing for a mathematical/neoclassical theory-dominated reform. Resistance came from many students and some of the academic staff. Associate Professor Ted Wheelwright wrote to the Vice-Chancellor in 1970, calling for an official enquiry into the department. Several of the academics hired by Hogan and Simkin subsequently aligned themselves with Wheelwright, including: Debesh Bhattacharya, Gavan Butler, Frank Stilwell and Evan Jones. Students complained that their Economics courses were overly abstract and poorly taught. Their animosity was compounded when Paul Samuelson, arguably the most influential economist of the period, came to Sydney: his public lecture at the university was on a topic in mathematical economics that was met with dismay by most of the students and the lecture theatre was nearly empty by the time he had finished. A Radical Economics conference was organized in 1973 by three students — Steve Keen, Richard Fields and Greg Cough.

Since the United Nations-backed and NATO-led overthrow of Libyan leader Muammar Gaddafi's regime in 2011, Libya has been plagued by disorder and migrants with little cash and no papers have become vulnerable. Libya is a major exit point for African migrants heading to Europe. The International Organization for Migration (IOM) published a report in April 2017 showing that many of the migrants from West-Africa heading to Europe are sold as slaves after being detained by people smugglers or militia groups. African countries south of Libya were targeted for slave trading and transferred to Libyan slave markets instead. According to the victims, the price is higher for migrants with skills like painting and tiling. Slaves are often ransomed to their families and in the meantime until ransom can be tortured, forced to work, sometimes to death and eventually executed or left to starve if they can't pay for too long. Women are often raped and used as sex slaves and sold to brothels and private Libyan clients. Many child migrants also suffer from abuse and child rape in Libya.

For the past years, researchers have been trying to reduce the price of solar cells while maximizing efficiency. Thin-film solar cell is a cost-effective second generation solar cell with much reduced thickness at the expense of light absorption efficiency. Efforts to maximize light absorption efficiency with reduced thickness have been made. Surface texturing is one of techniques used to reduce optical losses to maximize light absorbed. Currently, surface texturing techniques on silicon photovoltaics are drawing much attention. Surface texturing could be done in multiple ways. Etching single crystalline silicon substrate can produce randomly distributed square based pyramids on the surface using anisotropic etchants. Recent studies show that c-Si wafers could be etched down to form nano-scale inverted pyramids. Multicrystalline silicon solar cells, due to poorer crystallographic quality, are less effective than single crystal solar cells, but mc-Si solar cells are still being used widely due to less manufacturing difficulties. It is reported that multicrystalline solar cells can be surface-textured to yield solar energy conversion efficiency comparable to that of monocrystalline silicon cells, through isotropic etching or photolithography techniques. Incident light rays onto a textured surface do not reflect back out to the air as opposed to rays onto a flat surface. Rather some light rays are bounced back onto the other surface again due to the geometry of the surface. This process significantly improves light to electricity conversion efficiency, due to increased light absorption. This texture effect as well as the interaction with other interfaces in the PV module is a challenging optical simulation task. A particularly efficient method for modeling and optimization is the OPTOS formalism. In 2012, researchers at MIT reported that c-Si films textured with nanoscale inverted pyramids could achieve light absorption comparable to 30 times thicker planar c-Si. In combination with anti-reflective coating, surface texturing technique can effectively trap light rays within a thin film silicon solar cell. Consequently, required thickness for solar cells decreases with the increased absorption of light rays.

In 1937 the Academy was divided, with the Senior Course Academy being relocated to Sagamihara in Kanagawa prefecture, and the Junior Course School moved to Asaka, Saitama. The 50th graduation ceremony was held in the new Academy buildings in Sagamihara on 20 December 1937, and was attended by the Shōwa Emperor (Emperor Hirohito) himself. In 1938, a separate school was established for military aviation officers. During World War II, the school was highly respected and faculty consisted of many Tokyo Imperial University alumni. It also accepted a large number of students from China, and many of those cadets later had prominent ranks in the Republic of China Armed Forces. In June 1945, as a precautionary measure due to Allied bombings, the Academy sent its entire staff and 3,000 students on a long-term bivouac in Nagano Prefecture, leaving the installation under a light guard as caretakers. In September 1945, after the surrender of Japan, a battalion of the U.S. Army’s 1st Cavalry Division took control of the Academy from the soldiers guarding it. The Academy was abolished along with the Imperial Japanese Army at the end of 1945, and its Sagamihara grounds are now part of the United States Army base of Camp Zama.

The Eisenhower Administration wanted to see regime change in Cuba after its communist revolution in 1959. In the summer of 1960, the CIA obtained fifteen World War II B-26 Invader medium bombers from storage at Davis-Monthan AFB, Arizona and had them refurbished. To fly these aircraft, Cuban exile pilots needed to be trained in their operations. Searching for B-26 instructors and maintenance personnel, the CIA became aware of an organization that had exactly the people it needed: The Alabama Air National Guard. Specifically, the 106th Tactical Reconnaissance Squadron at Birmingham was the last Air National Guard organization to fly the B-26, having retired its old bombers just three years earlier in 1957. Working discreetly through the Alabama Adjutant General's office, the Air Commando Major attached to the CIA (who was born and raised in Alabama) made arrangements for some Alabama ANG pilots and maintenance crews to train the Cubans in the B-26. In less than two months, eighty American instructors were transported to a secret CIA air base at Puerto Cabezas Airport, Nicaragua, to begin training the Cuban exiles. Both B-26 ground attack missions along with C-46 paratrooper training for the exile's airborne forces were emphasized. The Alabama ANG instructor pilots were told prior to volunteering that their primary mission was to train Cuban exile aircrews; they were not going to fly in combat unless it was a last resort.

Wood is also composed of nanotubes or “nanofibrils”; namely, lignocellulosic (woody tissue) elements which are twice as strong as steel. Harvesting these nanofibrils would lead to a new paradigm in sustainable construction as both the production and use would be part of a renewable cycle. Some developers have speculated that building functionality onto lignocellulosic surfaces at the nanoscale could open new opportunities for such things as self-sterilizing surfaces, internal self-repair, and electronic lignocellulosic devices. These non-obtrusive active or passive nanoscale sensors would provide feedback on product performance and environmental conditions during service by monitoring structural loads, temperatures, moisture content, decay fungi, heat losses or gains, and loss of conditioned air. Currently, however, research in these areas appears limited.

Starting in September 1940, IFF equipment was installed. This weighed about 40 lb (18 kg) and could be identified by wire aerials strung between the tailplane tips and rear fuselage. Although the added weight and the aerials reduced maximum speed by about two mph (three km/h), it allowed the aircraft to be identified as "friendly" on radar: lack of such equipment was a factor leading to the Battle of Barking Creek. At about the same time new VHF T/R Type 1133 radios started replacing the HF TR9 sets. These had first been fitted to Spitfires of 54 and 66 Squadrons in May 1940, but ensuing production delays meant the bulk of Spitfires and Hurricanes were not fitted for another five months. The pilots enjoyed a much clearer reception which was a big advantage with the adoption of Wing formations throughout the RAF in 1941. The new installation meant that the wire running between the aerial mast and rudder could be removed, as could the triangular "prong" on the mast.

In May 2013, GlassPoint Solar and Petroleum Development Oman (PDO) commissioned the Middle East's first solar EOR project. PDO is a joint venture between the Sultanate of Oman, Shell and Total. The 7 MW solar EOR facility produces a daily average of 50 tons of emissions-free steam that feeds directly into existing thermal EOR operations at PDO's Amal West field in Southern Oman. The system in 27 times larger than GlassPoint's first installation at Berry Petroleum's 21Z oil field. Reports by Petroleum Development Oman indicate that the pilot was delivered on-time, under-budget, and above contract output specifications, with zero lost time injuries. In the first year of operations, the fully automated system successfully exceeded all performance tests and production targets. The system recorded a 98.6% uptime, significantly exceeding PDO's expectations. Even during severe dust and sandstorms, the system has proven to maintain regular operations.

The MIL-STD-810 test series originally addressed generic laboratory environmental testing. The first edition of MIL-STD-810 in 1962 included only a single sentence allowing users to modify tests to reflect environmental conditions. Subsequent editions contained essentially the same phrase, but did not elaborate on the subject until MIL-STD-810D was issued marking one of the more significant revisions of the standard with its focus more on shock and vibration tests that closely mirrored real-world operating environments. MIL-STD-810F further defined test methods while continuing the concept of creating test chambers that simulate conditions likely to be encountered during a product's useful life rather than simply replicating the actual environments. More recently, MIL-STD-810G implements Test Method 527 calling for the use of multiple vibration exciters to perform multi-axis shaking that simultaneously excites all test article resonances and simulates real-world vibrations. This approach replaces the legacy approach of three distinct tests, that is, shaking a load first in its "x" axis, then its "y" axis, and finally in its "z" axis.

In 2018, a new version was described by most of the same authors in the "Journal of the American Chemical Society", in which the cathode is coated with a special plasticiser solution to avoid interface cracking as different materials expand at different rates. Braga says the new battery has twice the energy density of conventional lithium ion batteries, and can be recharged 23,000 times. Critics pointed out several extraordinary claims in the paper, such as a record-high relative dielectric constant; perhaps higher than any material recorded, and a raise in the capacitance of the battery over many charge cycles, rather than a decrease as is usually the case with all other battery technologies. The paper was also not clear if the battery could hold its charge after it is unplugged, which would clarify whether it is really a new battery technology, or simply a capacitor. Braga responded to critics, saying "Data is data, and we have similar data from many different cells, in four different instruments, different labs, glove box. And at the end of the day, the LEDs are lit for days with a very small amount of active material after having cycled for more than 23,000 times".

With the introduction of XstreamCORE ATTO launched two new technologies to help their products stand out against competing architectures. xCORE IO Acceleration features multiple parallel IO acceleration engines with end to end IO processing, hardware buffer allocation management and real-time performance and latency analytics. These features combine to provide very high, reliable throughput and IOPS with deterministic latency of under 4 microseconds. Unlike general purpose processor based architectures xCORE maintains performance and latency as services and features are added. This is accomplished with the help of ATTO's other new technology the eCORE Control Engine. eCORE offloads non-data related commands from xCORE and adds common, open storage services, integrates with industry standard APIs, manages reservations, storage routing and host and mapping functions. The eCORE Control Engine also manages traffic for data mover offload with added error handling and diagnostic tools. These features add value to JBOD, JBOF or RAID storage while providing tight integration with server based software.

The first indications of changes in the structure of some sources were obtained by an American-Australian team in a series of transpacific VLBI observations between 1968 and 1970 (Gubbay et al. 1969). Following the early experiments, they had realised the potential of the NASA tracking antennas for VLBI measurements and set up an interferometer operating between California and Australia. The change in the source visibility that they measured for 3C 279, combined with changes in total flux density, indicated that a component first seen in 1969 had reached a diameter of about 1 milliarcsecond, implying expansion at an apparent velocity of at least twice the speed of light. Aware of Rees's model, (Moffet et al. 1972) concluded that their measurement presented evidence for relativistic expansion of this component. This interpretation, although by no means unique, was later confirmed, and in hindsight it seems fair to say that their experiment was the first interferometric measurement of superluminal expansion.

Following his doctoral research, Wallraff continued to work as a research scientist and later as an assistant professor at the University of Erlangen-Nuremberg. In 2002, he left Europe to work as a postdoctoral researcher with Robert J. Schoelkopf within the Department of Applied Physics at Yale University in New Haven, Connecticut. During this time, he was an author on papers regarding the coupling of superconducting qubits via a cavity bus and the coherent interaction of a single photon to a Cooper-pair box, among others. In 2004 he was appointed as an associate research scientist in the Department of Applied Physics at Yale and in June 2005 he was elected as a tenure-track assistant professor at ETH Zürich. Following the professorship appointment, he departed from Yale and started the Quantum Device Lab at ETH Zürich in January 2006. In 2011, he was chosen from among 380 ETH Zürich professors to be awarded the Prize for his research activities. In 2012, he worked as a visiting professor at the Kastler-Brossel Laboratory within the École Normale Supérieure in Paris, France.

This issue has caused a well known problem in the analysis of DNA, for example in bioinformatics. As first reported in 2004, genetic scientists found that Excel automatically and incorrectly converts certain gene names into dates. A follow-up study in 2016 found many peer reviewed scientific journal papers had been affected and that "Of the selected journals, the proportion of published articles with Excel files containing gene lists that are affected by gene name errors is 19.6 %." Excel parses the copied and pasted data and sometimes changes them depending on what it thinks they are. For example, MARCH1 (Membrane Associated Ring-CH-type finger 1) gets converted to the date March 1 (1-Mar) and SEPT2 (Septin 2) is converted into September 2 (2-Sep) etc. While some secondary news sources reported this as a fault with Excel, the original authors of the 2016 paper placed the blame with the researchers misusing Excel.

Risk factors include catheter use and chronic urinary tract infections, being female, diabetes mellitus, neurogenic bladder, and being in an immunocompromised state. In 50% of cases, patients are elderly and diabetic. Obstruction of the urinary tract as well as urinary stasis, often brought on by paralysis of the urinary tract, are also major risk factors in addition to diabetes. Transplant recipients have also been found to be at risk. Introduction of infection from external means was discovered in one case study where a male with no history of diabetes or abnormalities to his immune system had recently undergone a transrectal ultrasound needle-guided prostate biopsy contracted a severe case of sepsis, which led to a case of Emphysematous cystitis. The patient went on to develop disseminated intravascular coagulopathy and acute respiratory distress syndrome. After a stay in Intensive Care undergoing broad-spectrum antibiotic therapy, the patient was eventually discharged in stable condition. Patients diagnosed with Emphysematous Cystitis are also commonly diagnosed with urinary tract infections and sepsis. Cases of Emphysematous Cystitis in a clinical study have shown to progress quickly and are life-threatening and sometimes fatal due to inflammation caused by gas forming organisms.

Kao, together with his new team (members including T. W. Davies, M. W. Jones, and C. R. Wright), pursued this goal by testing various materials. They precisely measured the attenuation of light with different wavelengths in glasses and other materials. During this period, Kao pointed out that the high purity of fused silica (SiO) made it an ideal candidate for optical communication. Kao also stated that the impurity of glass material is the main cause for the dramatic decay of light transmission inside glass fiber, rather than fundamental physical effects such as scattering as many physicists thought at that time, and such impurity could be removed. This led to a worldwide study and production of high-purity glass fibers. When Kao first proposed that such glass fiber could be used for long-distance information transfer and could replace copper wires which were used for telecommunication during that era, his ideas were widely disbelieved; later people realized that Kao's ideas revolutionized the whole communication technology and industry.

In 2013, Captain Kenneth Coleman, the U.S. Navy's requirements officer for the program, identified the LCS as being especially vulnerable to tactical aircraft armed with standoff anti-ship missiles. Vice Admiral Thomas H. Copeman III is reported to be considering an upsized "Super" LCS, with space to install needed firepower, because he noted that the 57 mm main gun was more suitable to a patrol boat than a frigate. Austal's vice president for sales, Craig Hooper, suggested that the ships should instead be used for UAV operations. Navy Secretary Ray Mabus has called the lack of identified missions for the LCS "one of its greatest strengths". The various modules all use the same Internet Protocol formats. In 2013 Congressional auditors found that the ships lacked robust communications systems and a USN review "uncovered classified deficiencies" in the ship's cyberdefenses.

When Feynman was 15, he taught himself trigonometry, advanced algebra, infinite series, analytic geometry, and both differential and integral calculus. Before entering college, he was experimenting with mathematical topics such as the half-derivative using his own notation. He created special symbols for logarithm, sine, cosine and tangent functions so they did not look like three variables multiplied together, and for the derivative, to remove the temptation of canceling out the formula_1's in formula_2. A member of the Arista Honor Society, in his last year in high school he won the New York University Math Championship. His habit of direct characterization sometimes rattled more conventional thinkers; for example, one of his questions, when learning feline anatomy, was "Do you have a map of the cat?" (referring to an anatomical chart).

Most of the difficulty in the design of a superscalar CPU architecture lies in creating an effective dispatcher. The dispatcher needs to be able to quickly determine whether instructions can be executed in parallel, as well as dispatch them in such a way as to keep as many execution units busy as possible. This requires that the instruction pipeline is filled as often as possible and requires significant amounts of CPU cache. It also makes hazard-avoiding techniques like branch prediction, speculative execution, register renaming, out-of-order execution and transactional memory crucial to maintaining high levels of performance. By attempting to predict which branch (or path) a conditional instruction will take, the CPU can minimize the number of times that the entire pipeline must wait until a conditional instruction is completed. Speculative execution often provides modest performance increases by executing portions of code that may not be needed after a conditional operation completes. Out-of-order execution somewhat rearranges the order in which instructions are executed to reduce delays due to data dependencies. Also in case of single instruction stream, multiple data stream—a case when a lot of data from the same type has to be processed—, modern processors can disable parts of the pipeline so that when a single instruction is executed many times, the CPU skips the fetch and decode phases and thus greatly increases performance on certain occasions, especially in highly monotonous program engines such as video creation software and photo processing.

Spiradenoma tumors occur in individuals of various ages but tend to develop in middle-aged and elder adults (e.g. in a study of 27 patients, the median age at diagnosis was 62 years). However, cases have been reported in children as young as 2 years. These tumors usually present as a solitary, sometimes painful, slowly growing, 1–2 cm (i.e. centimeters), gray-to-pink nodules that lie underneath the skin's epidermis in the head, neck, trunk, arms, or legs. However, these nodules have been reported to be as large as 6 cm and to occur in other hair follicle-containing cutaneious sites such as the vulva, breast, and breast nipple. Areas of the skin that do not have hair follicles (e.g. palms of the hands and soles of feet) do not develop these nodules. Less than 2% of cases present with more than one nodule; the multiple nodules in SA tend to array in a linear, blaschkoid (i.e. V-, U-, or inverted U-shaped), or zosteriform (i.e. belt- or girdle-shape tracking an area of skin served by a sensory nerve) patterns. Giant vascular eccrine spiradenomas are larger (> 2 cm) and more highly vascular variants of SA that usually develop at the same cutaneous sites as SA but have also been reported to occur in the abdomen and scrotum. No malignant giant vascular SA has been described in the literature to date (2021).

Australian biologist and Professor of Genetics David Andrew Sinclair notes that "the new technologies with genome editing will allow it to be used on individuals (...) to have (...) healthier children"designer babies. According to a September 2016 report by the Nuffield Council on Bioethics in the future it may be possible to enhance people with genes from other organisms or wholly synthetic genes to for example improve night vision and sense of smell. George Church has compiled a list of potential genetic modifications for possibly advantageous traits such as less need for sleep, cognition-related changes that protect against Alzheimer's disease, disease resistances and enhanced learning abilities along with some of the associated studies and potential negative effects.

Money and the Hopkins family team persuaded the baby's parents that sex reassignment surgery would be in Reimer's best interest. At the age of 22 months, David underwent a bilateral orchidectomy, in which his testes were surgically removed and a rudimentary vulva was fashioned. David was reassigned to be raised as female and given the name Brenda (similar to his birth name, "Bruce"). Psychological support for the reassignment and surgery was provided by John Money, who continued to see Reimer annually for consultations and to assess the outcome. This reassignment was considered an especially important test case of the social learning concept of gender identity for two reasons: first, Reimer's identical twin brother, Brian, made an ideal control because the brothers shared genes, family environments, and the intrauterine environment; second, this was reputed to be the first reassignment and reconstruction performed on a male infant who had no abnormality of prenatal or early postnatal sexual differentiation.

It is difficult to set up a comprehensive surveillance system for measuring rates of change in antibiotic resistance. The US Government Accountability Office published a report in 2011 stating that government and commercial agencies had not been collecting sufficient data to make a decision about best practices. There is also no regulatory agency in the United States that systematically collects detailed data on antibiotic use in humans and animals, which means it is not clear which antibiotics are prescribed for which purpose and at what time. While this may be lacking at a regulatory level, the US poultry meat sector has been working on the issue of data collection itself, and has now reported comparative data showing significant reductions in antibiotic use. Among the highlights in the report was a 95% decrease in in-feed tetracycline use in broiler chicks from 2013 to 2017, a 67% reduction in in-feed use of tetracycline in turkeys, and a 42% drop in hatchery use of gentamicin in turkey poults. This is an encouraging sign; the 53% overall reduction in antibiotic use seen in the UK between 2013 and 2018 was initiated from a voluntary stewardship programme developed by the UK poultry meat sector.

Speculations that the Roman dictator Julius Caesar was born by the method now known as C-section are false. Although caesarean sections were performed in Roman times, no classical source records a mother surviving such a delivery. As late as the 12th century, scholar and physician Maimonides expresses doubt over the possibility of a woman's surviving this procedure and again becoming pregnant. The term has also been explained as deriving from the verb "caedere", "to cut", with children delivered this way referred to as "caesones". Pliny the Elder refers to a certain Julius Caesar (an ancestor of the famous Roman statesman) as "ab utero caeso", "cut from the womb" giving this as an explanation for the cognomen "Caesar" which was then carried by his descendants. Nonetheless, the false etymology has been widely repeated until recently. For example, the first (1888) and second (1989) editions of the "Oxford English Dictionary" say that caesarean birth "was done in the case of Julius Cæsar". More recent dictionaries are more diffident: the online edition of the OED (2021) mentions "the traditional belief that Julius Cæsar was delivered this way", and "Merriam-Webster's Collegiate Dictionary" (2003) says "from the legendary association of such a delivery with the Roman cognomen "Caesar"".

The assay of superoxide generated in biological systems is a difficult task because of its high reactivity and short half-life. One approach that has been used in quantitative assays converts superoxide to hydrogen peroxide, which is relatively stable. Hydrogen peroxide is then assayed by a fluorimetric method. As a free radical, superoxide has a strong EPR signal, and it is possible to detect superoxide directly using this method when it is abundant enough. For practical purposes, this can be achieved only in vitro under non-physiological conditions, such as high pH (which slows the spontaneous dismutation) with the enzyme xanthine oxidase. Researchers have developed a series of tool compounds termed "spin traps" that can react with superoxide, forming a meta-stable radical (half-life 1–15 minutes), which can be more readily detected by EPR. Superoxide spin-trapping was initially carried out with DMPO, but phosphorus derivatives with improved half-lives, such as DEPPMPO and DIPPMPO, have become more widely used.

The production of phytoplankton under artificial conditions is itself a form of aquaculture. Phytoplankton is cultured for a variety of purposes, including foodstock for other aquacultured organisms, a nutritional supplement for captive invertebrates in aquaria. Culture sizes range from small-scale laboratory cultures of less than 1L to several tens of thousands of litres for commercial aquaculture. Regardless of the size of the culture, certain conditions must be provided for efficient growth of plankton. The majority of cultured plankton is marine, and seawater of a specific gravity of 1.010 to 1.026 may be used as a culture medium. This water must be sterilized, usually by either high temperatures in an autoclave or by exposure to ultraviolet radiation, to prevent biological contamination of the culture. Various fertilizers are added to the culture medium to facilitate the growth of plankton. A culture must be aerated or agitated in some way to keep plankton suspended, as well as to provide dissolved carbon dioxide for photosynthesis. In addition to constant aeration, most cultures are manually mixed or stirred on a regular basis. Light must be provided for the growth of phytoplankton. The colour temperature of illumination should be approximately 6,500 K, but values from 4,000 K to upwards of 20,000 K have been used successfully. The duration of light exposure should be approximately 16 hours daily; this is the most efficient artificial day length.

Differences of bureaucracy procedures and technical aspects related to the official national norm “Planeación, Operación y Acceso al Sistema Eléctrico Nacional” (POASEN, in Spanish) on introducing distributed generation have been occurring and causing delays in its implementation through the last years among the main actors of the solar sector: the Ministry of Environment and Energy (MINAE), the Autoridad Reguladora de Servicios Públicos (ARESEP, in Spanish, a public entity that fixes prices and standards on public services), the electricity agencies of the country and the private companies that supply solar panels. One of the main discrepancies between MINAE and ARESEP was the legal nature of net metering, being solved by the Attorney General of the Republic (Procuraduría General de la República, in Spanish) in June 2015. The final resolution stated that distributed generation for self-consumption is not considered a public service in Costa Rica. In October 2015, the government finally published the required regulatory framework that entered into operation in April 2016.

In her 2001 book, "The Ghosts of Evolution", Connie Barlow suggested that "T. taxifolia" may be an evolutionary anachronism similar to the Osage orange ("Maclura pomifera") and Kentucky coffeetree ("Gymnocladus dioicus"), which are thought to have been dispersed by now-extinct megafauna, such as the mastodon. Barlow suggested that the original seed disperser of Torreya might have been a now-extinct large tortoise. In the Winter 2004/2005 issue of "Wild Earth" magazine, an article by Barlow and Paul S. Martin titled "Bring "Torreya taxifolia" North — Now" offered another possible cause of dispersal problems as the glaciers retreated: extirpation of local squirrels by newly arrived Paleo-Indians inhabiting the riverside habitat and possibly also setting fires destructive of the species. Barlow's hypothesis later shifted to an intrinsic topographical barrier: perhaps "the large-seed of Torreya (which is sometimes capable of floating for several days) easily caught a fast and obstacle-free river ride southward from the Appalachian Mountains by way of the Chattahoochee River at the onset of cooling during the Pliocene or Pleistocene. But there was no river-flow way to return north during any of the interglacial warmings."

A new type of magnetic storage, called magnetoresistive random-access memory or MRAM, is being produced that stores data in magnetic bits based on the tunnel magnetoresistance (TMR) effect. Its advantage is non-volatility, low power usage, and good shock robustness. The 1st generation that was developed was produced by Everspin Technologies, and utilized field induced writing. The 2nd generation is being developed through two approaches: thermal-assisted switching (TAS) which is currently being developed by Crocus Technology, and spin-transfer torque (STT) on which Crocus, Hynix, IBM, and several other companies are working. However, with storage density and capacity orders of magnitude smaller than an HDD, MRAM is useful in applications where moderate amounts of storage with a need for very frequent updates are required, which flash memory cannot support due to its limited write endurance. Six state MRAM is also being developed, echoing four bit multi level flash memory cells, that have six different bits, as opposed to two.

The ocean can be described as the world's largest ecosystem and it's home for many species of marine life. Different activities done and caused by human beings as mentioned before such as global warming, ocean acidification, and pollution affects marine life and its habitats. For the past 50 years, more than 90 percent of global warming brung on by humans has been consumed into the ocean. This results in the rise of ocean temperatures and ocean acidification which is harmful to many fish species and causes damage to habitats such as coral. With coral producing materials such as carbonate rock and calcareous sediment, this creates a very unique and valuable ecosystem not only providing food/homes for marine creatures but also having many benefits for humans too. Ocean acidification caused by rising levels of Carbon dioxide leads to coral bleaching where the rates of calcification is lowered affecting coral growth. Additionally, another issue caused by humans which impacts marine life is pollution and the use of plastics. The process by which humans use and get rid of plastic can officially be marked as an Anthropocene which can be described as a time period where humans directly have an influence on what goes on in the world's environment.According to the IPCC (2019), since 1950 "many marine species across various groups have undergone shifts in geographical range and seasonal activities in response to ocean warming, sea ice change and biogeochemical changes, such as oxygen loss, to their habitats."

Magnum Bonum indeed proved to be a commercial success and soon became the best-selling variety grown in Great Britain. Its ability to survive hard frosts recommended it to Scottish growers in particular. It was a white, kidney-shaped late maincrop with a floury texture and a blandly sweet flavour that grew vigorously, withstood disease, and gave good yields. In 1880, reporting on the 7th annual Potato Show held at the Crystal Palace, "The Times" said: "To ascertain and announce which is the most serviceable potato would be a great national service. There is a very considerable consensus of opinion that in a great number of soils Messrs. Sutton's 'Magnum Bonum' has survived in bad years, and yielded abundantly in good. It is a recent introduction, and the breeder who first raised it in 1871, Mr. Clark, of Christchurch, was present yesterday at the show. It has been supplied to the Marquis of Lansdowne and other landed proprietors in Ireland, and to one of the Dublin relief funds, and is stated to have answered admirably in the humid soil of Ireland."

However, all Equidae in North America ultimately became extinct. The causes of this extinction (simultaneous with the extinctions of a variety of other American megafauna) have been a matter of debate. Given the suddenness of the event and because these mammals had been flourishing for millions of years previously, something quite unusual must have happened. The first main hypothesis attributes extinction to climate change. For example, in Alaska, beginning approximately 12,500 years ago, the grasses characteristic of a steppe ecosystem gave way to shrub tundra, which was covered with unpalatable plants. The other hypothesis suggests extinction was linked to overexploitation by newly arrived humans of naive prey that were not habituated to their hunting methods. The extinctions were roughly simultaneous with the end of the most recent glacial advance and the appearance of the big game-hunting Clovis culture. Several studies have indicated humans probably arrived in Alaska at the same time or shortly before the local extinction of horses. However, a 2021 study describing archaeological evidence suggesting humans arrived much earlier raises new questions about this theory. Additionally, it has been proposed that the steppe-tundra vegetation transition in Beringia may have been a consequence, rather than a cause, of the extinction of megafaunal grazers.

Despite all this research, there were relatively few recordings available to the general public. This changed in 1998, when Hermann Max conducted a CD of Graupner works on the CPO label. Montreal harpsichordist Geneviève Soly came across a Graupner manuscript in the Beinecke Library at Yale University in the year 2000 and started performing and recording his works. Graupner was "always on the cutting edge for his time and very innovative in his ideas for harmony, notation, and the use of instruments," as Soly has noted. "You have to take into consideration his various styles in relation to the actual period and the ideas he was interested in developing at that moment. The size of the catalogue imposes added difficulties in this respect, because another composer might have written for just as long, but in one style only. Mozart comes to mind: although he composed over a shorter period, his style was always well defined."

In the cooperative campaign, a separate story involves two robotic characters and GLaDOS. The designers initially planned to use Chell and a new human character called "Mel". GLaDOS' dialogue would play off the humans' "image issues", and this aspect was retained after the designers switched to using robots. GLaDOS seems troubled by the robots' cooperation, and tries to aggravate their relationship through psychological tactics, such as praising one robot over the other. Valve initially considered having GLaDOS deliver separate lines to each player, but they found this to be a significant effort for minimal benefit. The writers also tried adding lines for GLaDOS that would encourage the players to compete against each other for rewards, such as meaningless points, but playtesters did not respond well. Faliszek said that in cooperative games, it can be difficult to deliver key dialogue or in-game events to players, who may not be looking in the right direction at the right time. Instead, using their experience from previous games, Faliszek and Wolpaw kept the story and key comedic lines short, and repeated them frequently.

Due to its radioactivity, curium and its compounds must be handled in appropriate labs under special arrangements. While curium itself mostly emits α-particles which are absorbed by thin layers of common materials, some of its decay products emit significant fractions of beta and gamma rays, which require a more elaborate protection. If consumed, curium is excreted within a few days and only 0.05% is absorbed in the blood. From there, ~45% goes to the liver, 45% to the bones, and the remaining 10% is excreted. In bone, curium accumulates on the inside of the interfaces to the bone marrow and does not significantly redistribute with time; its radiation destroys bone marrow and thus stops red blood cell creation. The biological half-life of curium is about 20 years in the liver and 50 years in the bones. Curium is absorbed in the body much more strongly via inhalation, and the allowed total dose of Cm in soluble form is 0.3 μCi. Intravenous injection of Cm- and Cm-containing solutions to rats increased the incidence of bone tumor, and inhalation promoted lung and liver cancer.

United States government agencies, at both Federal and State levels, have initiated a number of programs which include encouraging workers to bike to work rather than to drive. The Fitness Portal provides a range of tools, examples, and case studies of organization ideas. A few examples given by the Fitness Portal include: using the push mower, going for a walk, taking the stairs instead of an elevator, biking, running errands, visiting friends, cleaning out the garage or the attic, volunteering to become a coach or referee, signing up for a group exercise class, joining a softball league, or parking at the farthest end of the parking lot. For children they suggest: taking a dog for a walk, starting up a kickball game, joining a sports team, going to the park, helping their parents with yard work, playing tag, riding their bike to school, walking to the store, seeing how many jumping jacks they can do, or racing a friend to the end of the block.

In addition to regular campus courses, the university offers 22 semester-long off-campus study groups each year, including programs in Australia, China, Japan, India, several Western European countries, Washington, D.C., and the National Institutes of Health. Approximately two-thirds of Colgate undergraduates study abroad, which is a high proportion compared to other colleges and universities in the United States. About 95% of seniors graduate and most alumni proceed to graduate schools in law, administration, engineering, medicine, the arts, and the sciences, as well as to financial, administrative or scientific occupations. In partnership similar to that of Haverford and Swarthmore, Colgate students are also able to enroll in classes at Hamilton College, another nearby selective liberal arts school.

There is a considerable overlap between geomorphology and other fields. Deposition of material is extremely important in sedimentology. Weathering is the chemical and physical disruption of earth materials in place on exposure to atmospheric or near surface agents, and is typically studied by soil scientists and environmental chemists, but is an essential component of geomorphology because it is what provides the material that can be moved in the first place. Civil and environmental engineers are concerned with erosion and sediment transport, especially related to canals, slope stability (and natural hazards), water quality, coastal environmental management, transport of contaminants, and stream restoration. Glaciers can cause extensive erosion and deposition in a short period of time, making them extremely important entities in the high latitudes and meaning that they set the conditions in the headwaters of mountain-born streams; glaciology therefore is important in geomorphology.

Whilst working at the National Hospital for Neurology and Neurosurgery, Queen Square, as a medical research fellow to Clare Fowler, they developed a technique of injecting botox into the bladder wall to target bladder nerves for treating urinary incontinence due to an overactive bladder that did not respond to traditional measures and usual medications. They were the first in the UK to use this method using a flexible cystoscope. The procedure does not require an operating room or general anaesthetic. In 2002 he was appointed consultant urologist to Guy's Hospital. Three years later, his Botox technique was presented at the 2005 BAUS Annual Scientific Meeting in Glasgow and became known as the 'Dasgupta technique'. He was a co-principal investigator in the first randomized, double-blind, placebo-controlled study pertaining to the procedure, conducted at Guy's Hospital, and it was included as a second-line treatment for refractory overactive bladder by the UK's National Institute for Health and Care Excellence (NICE) in 2006. It was endorsed by the Royal College of Obstetricians and Gynaecologists in 2014, as a second-line option following failure of other treatments. Others have since used and modified the procedure.

Kakalios earned his B.S. degree from City College of New York in 1979 and his M.S. and PhD degrees from the University of Chicago in 1982 and 1985. He began his comic book collection as a graduate student as a way to relieve stress. At Minnesota, he taught a freshman seminar that focused on the physics of superheroes as a way to motivate students to think about physics. This course gained great popularity as an enticing alternative to the typical inclined planes and pulleys of physics.The seminar was a great success, leading to articles in popular magazines including "People", lectures on the subject, and publication of "The Physics of Superheroes". In his talks, favorite examples are the death of Gwen Stacy (Spider-Man's girlfriend), "can Superman jump over tall buildings and what does this tell us about Krypton?", the high-velocity actions of The Flash, and the shrinking problem of the Atom. His analysis of Gwen Stacy's death eventually became integral to the plot of a new Spider-Man comic.

Though the two aircraft were competing for the same role, they were fairly different in design approach. The twin-engine F-15E Strike Eagle is basically an F-15D two-seat trainer with the back-seat station modified to support ground-attack instruments. The single-engine F-16XL has major structural and aerodynamic differences from the original F-16 Fighting Falcon, resulting in a promising design which, with its radically redesigned cranked-delta wing, greatly boosted performance; if selected, the single- and two-seat versions were to be designated F-16E and F-16F, respectively. As such, the XL would have required much more effort, time and money to put into full production. Additionally, the Strike Eagle has two engines, which gives it more thrust and capacity to carry more weapons and/or armor. Furthermore, engine redundancy can be very useful for an aircraft whose mission involves operating within the reach of anti-aircraft artillery and surface-to-air missiles, in addition to the standard threats of fighter aircraft and interceptors.

The United Kingdom has at least 33 tornadoes per year, more than any other country in the world relative to its land area. Though these tornadoes are much weaker than in areas of the United States, there is a significant number of these tornadoes annually. Dr. Ted Fujita (inventor of the Fujita scale), an American meteorologist, was the first to recognise the UK as the top site for tornadoes in 1973. Although most tornadoes are weak, there are occasional destructive events, for example, the Birmingham tornado of 2005 and the London tornado of 2006. Both registered F2 on the Fujita scale and both caused significant damage and injury. The largest ever recorded was thought to have been an F4, again in London in 1091. The most deadly occurred on 28 December 1879. All 74 lives were lost when a passenger train plunged from the Tay Bridge (Tayside) into the Tay Estuary, when the middle section of the bridge collapsed. Although the bridge was poorly constructed and had already been weakened in earlier gales (including the pre-existing winds at the time of the tragedy), the ultimate failure is believed to have been caused by two or three waterspouts which were sighted close to the bridge immediately before the accident. A tornado also developed in London on 3 July 2007.

Eaton has spent his entire career at the NIH after arriving as a medical officer in the Public Health Service in January 1968, leaving only once for a significant period of time to teach physical chemistry as a Visiting Professor at Harvard for the Spring semester of 1976. In 1972, he was tenured in the then-new Laboratory of Chemical Physics and became its chief in 1986. Eaton's early work at NIH built on his work on heme proteins, focusing mainly on hemoglobin and the abnormal aggregation of the mutant form of the protein found in sickle-cell anemia. In the early 1990s, Eaton began to focus on theoretical and experimental studies of protein folding and has been particularly influential in the study of fast-folding proteins and applications of single molecule fluorescence spectroscopy.

Because of the high mineralization, several mines have opened in the belt. Sherman Mine, northwest of the town of Temagami, was a major producer of iron ore. Mining operations began in 1968, and workings consisted of seven open pits: North Pit, East Pit, South Pit, West Pit and three relatively small open pits known as the Turtle Pits. A railroad was built from the Ontario Northland Railway to Sherman Mine in the 1960s to make transportation and shipping of iron ore easier and faster across Ontario. To the north, Temagami North was constructed as a resource town in the 1960s to supply Sherman Mine. With an average overall grade of 25% iron, the mine produced approximately 10,700 tons of crude ore per day and its mill capacity was of iron ore pellets per year. Operations at Sherman Mine ceased in 1990 after its owner Dofasco announced that they would be closing the mine. The municipality of Temagami made several approaches to Dofasco before the closer of Sherman Mine, offering a partnership in the community's future in terms of shared funding for a Sherman Park. However, it was informed during discussions with Dofasco's media executives that in the future they could not be counted on for maintenance funds for parks or anything else that was being done in partnership with the community. This caused a large attitudinal change from a few months earlier when the mine was associated with much of Temagami. The closure also had a significant impact on the economy of Temagami. There is still iron ore at Sherman Mine, but Dofasco were able to obtain it more cheaply elsewhere.

The severe climatic changes during the Ice Age had major impacts on the fauna and flora. With each advance of the ice, large areas of the continents became totally depopulated, and plants and animals retreating southwards in front of the advancing glacier faced tremendous stress. The most severe stress resulted from drastic climatic changes, reduced living space, and curtailed food supply. A major extinction event of large mammals (megafauna), which included mammoths, mastodons, saber-toothed cats, "glyptodons", the woolly rhinoceros, various giraffids, such as the Sivatherium; ground sloths, Irish elk, cave bears, Gomphotheres, dire wolves, and short-faced bears, began late in the Pleistocene and continued into the Holocene. Neanderthals also became extinct during this period. At the end of the last ice age, cold-blooded animals, smaller mammals like wood mice, migratory birds, and swifter animals like whitetail deer had replaced the megafauna and migrated north. Late Pleistocene bighorn sheep were more slender and had longer legs than their descendants today. Scientists believe that the change in predator fauna after the late Pleistocene extinctions resulted in a change of body shape as the species adapted for increased power rather than speed.

The next stop, Station 6, was a blocky crater, where the astronauts believed they could sample the Cayley Formation as evidenced by the firmer soil found there. Bypassing station seven to save time, they arrived at Station 8 on the lower flank of Stone Mountain, where they sampled material on a ray from South Ray crater for about an hour. There, they collected black and white breccias and smaller, crystalline rocks rich in plagioclase. At Station 9, an area known as the "Vacant Lot", which was believed to be free of ejecta from South Ray, they spent about 40 minutes gathering samples. Twenty-five minutes after departing the Vacant Lot, they arrived at the final stop of the day, halfway between the ALSEP site and the LM. There, they dug a double core and conducted several penetrometer tests along a line stretching east of the ALSEP. At the request of Young and Duke, the moonwalk was extended by ten minutes. After returning to the LM to wrap up the second lunar excursion, they climbed back inside the landing craft's cabin, sealing and pressurizing the interior after 7hours, 23 minutes, and 26 seconds of EVA time, breaking a record that had been set on Apollo 15. After eating a meal and proceeding with a debriefing on the day's activities with Mission Control, they reconfigured the LM cabin and prepared for the sleep period.

Weightless-N is designed around a differential binary phase shift keying (DBPSK) digital modulation scheme to transmit within narrow frequency bands using a frequency hopping algorithm for interference mitigation and enhanced security. It provides for encryption and implicit authentication using a shared secret key regime to encode transmitted information via a 128-bit AES algorithm. The technology supports mobility with the network automatically routing terminal messages to the correct destination. Multiple networks, typically operated by different companies, are enabled and can be co-located. Each base station queries a central database to determine which network the terminal is registered to in order to decode and route data accordingly.

Hayek (1935, 1937, 1940, 1945) stressed the knowledge problem of central planning, partly because decentralized socialism seemed indefensible. Part of the reason that Hayek stressed the knowledge problem was also because he was mainly concerned with debating the proposal for market socialism and the Lange model by Oskar R. Lange (1938) and Hayek's student Abba Lerner (1934, 1937, 1938) which was developed in response to the calculation argument. Lange and Lerner conceded that prices were necessary in socialism. Lange and Lerner thought that socialist officials could simulate some markets (mainly spot markets) and the simulation of spot markets was enough to make socialism reasonably efficient. Lange argued that prices can be seen merely as an accounting practice. In principle, claim market socialists, socialist managers of state enterprises could use a price system, as an accounting system, in order to minimize costs and convey information to other managers. However, while this can deal with existing stocks of goods, providing a basis for values can be ascertained, it does not deal with the investment in new capital stocks. Hayek responded by arguing that the simulation of markets in socialism would fail due to a lack of genuine competition and entrepreneurship. Central planners would still have to plan production without the aid of economically meaningful prices. Lange and Lerner also admitted that socialism would lack any simulation of financial markets, and that this would cause problems in planning capital investment.

A semiconductor is a material, which has an electrical conductivity value falling between that of a conductor, such as copper, and an insulator, such as glass. Its resistivity falls as its temperature rises; metals behave in the opposite way. Its conducting properties may be altered in useful ways by introducing impurities ("doping") into the crystal structure. When two differently doped regions exist in the same crystal, a semiconductor junction is created. The behavior of charge carriers, which include electrons, ions, and electron holes, at these junctions is the basis of diodes, transistors, and most modern electronics. Some examples of semiconductors are silicon, germanium, gallium arsenide, and elements near the so-called "metalloid staircase" on the periodic table. After silicon, gallium arsenide is the second-most common semiconductor and is used in laser diodes, solar cells, microwave-frequency integrated circuits, and others. Silicon is a critical element for fabricating most electronic circuits.

Single nucleotide polymorphisms (SNPs) in GABRB2 were first associated with schizophrenia (SCZ) in Han Chinese, and confirmed subsequently for German, Portuguese, and Japanese SCZ patients. Furthermore, their significant associations have been extended to cognitive function, psychosis, and neuroleptic-induced tardive dyskinesia in schizophrenics. Recurrent copy number variations (CNVs) in GABRB2 were likewise associated with schizophrenia. GABRB2 expression was decreased in genotype and age-dependent manners, with reduced β2L/β2S ratios in schizophrenics serving as a key determinant of the response of receptor function to the energy status. The regulation of its expression by methylation and imprinting, as well as its N-glycosylation of the β2-subunit, were altered in SCZ. That GABRB2 is both a recombination hotspot and subject to positive selection could be an important factor in the widespread occurrence of SCZ. Gabrb2-knockout mice displayed schizophrenia-like behavior including prepulse inhibition deficit and antisocial behavior that were ameliorated by the antipsychotic risperidone, strongly supporting the proposal based on postmortem SCZ brains that GABRB2 represents the key genetic factor in SCZ etiology.

SAI filed for protection from creditors under the Canadian "Companies' Creditors Arrangement Act" in June 2006. At that time the company stated that it needed an investment of US$5.5M to continue production. The company was not able to secure the capital in Canada and indicated at that time that it might have to relocate production to attract financing from other sources. CEO Paul Costanzo indicated that factors involved in this situation included the dramatic fall in value of the US dollar against the Canadian dollar between 2003–2006, start-up and product improvement costs that were greater than expected and especially a venture capital environment in the Province of Quebec that Costanzo described as "dismal". He stated at the time, "We have simply been unable to attract sufficient capital to allow us to effectively exploit the obvious opportunity that we have with the SA-160, let alone fund our planned development of a diesel two-place and a four-place product." He indicated then that the company was focusing on certification of the SA-160's glass cockpit installation along with product cost reduction measures.

The lab focused on innovation in digital technology and human-machine interaction. MLE was said to have managed to recreate the creative play research atmosphere of the MIT Media Lab. By 2004 MLE was in full swing, and in the lab's short lifespan the researchers produced 21 refereed journal articles, 59 refereed full papers for conferences, and 62 refereed shorter papers for conferences, for a total of 142 refereed works. The facility achieved international recognition for a range of its work including EEG based mind-computer interfaces; the BumpList and Iso-phone. The latter two projects received honorary mention at the 2004 Prix Ars Electronica. Furthermore, MLE researchers regularly contributed to international research forums of the European Commission, the Association for Computing Machinery, and others concerned with advancing technologies and their constructive uses.

Archer trained a generation of design researchers, showing them how the procedures of scholarly research based on well-founded evidence and systematic analysis were as applicable in design as in the more traditional academic subjects. For design practice he argued there was a need for method and rigour, and for decisions to be recorded and explained so they could, if necessary, be defended. In the modern day, practitioners are familiar with these issues through the requirements of quality assurance, while in academia the Research Assessment Exercise has pushed even the art and design community into taking research seriously. Archer's ideas were radical and pioneering, and the very existence of his research department – in an art college – controversial. It was his own force of character and his persuasive ability to argue his case with absolute clarity and conviction that ensured the department's survival, and provided him with the opportunity to demonstrate that design is not just a craft skill but a knowledge-based discipline in its own right.

In the late 1970s, Teledyne Vehicle Systems carried out several studies on a highly mobile light tracked vehicle, which could be used for a variety of tasks. The in-house trials lasted from 1980 to 1981. In 1982, a detailed design had been decided on. This vehicle competed in the Armored Gun System (AGS) competition. The first prototype hull was completed in December 1983, and the turret was completed mid-1984. In October, testing took place in the Nevada test center on mobility and reliability, and in April 1985, the chassis and turret were united. A month later, the vehicle was presented for the first time at the U.S. Army Armor Conference at Fort Knox. In 1986 test firing took place. In 1992, the Expeditionary tank lost out in the AGS competition to United Defense's CCV-L, which was type classified as the M8 Armored Gun System. The Expeditionary tank was later offered to other nations by Teledyne and later General Dynamics, but was never bought.
