In 1955 Kalecki returned to Poland, never to work abroad for any extended period again. Hopeful for an opportunity to participate there in reforms that were socially advantageous, he believed that socialism would avoid the miseries brought by capitalist policies. He became economic advisor to the Office of the Council of Ministers. In 1957, he was appointed chairman of the Central Commission for Perspective Planning. The perspective plan had a time horizon of 1961 to 1975 and basically meant a practical implementation of Kalecki's theories of growth in socialist economies. However, the final plan developed by Kalecki was dismissed by board members as defeatist. Then things got worse, as related by Feiwel:

This system will increase lethality, mobility, survivability, command and control and overall protection of the troops. This environmental chamber study compared physiological responses of volunteers exercising in MOPP 0, MOPP 1, and MOPP 4 with equivalent SIPE configurations, including SIPE 4 with and without ambient air microclimate cooling (MCC). Responses to all uniforms were compared over 100 minutes of continuous treadmill walking at 30.0 deg C, 50% rh. Responses to MOPP 4 and SIPE 4 with no cooling were also compared over 100 minutes at 18.5 deg C, 50% rh. Responses to MOPP 4 and SIPE 4 MCC were compared over four hours of intermittent work-rest cycles at 30.0 deg C, .50% rh. There were no differences between MOPP 0 and SIPE 0, MOPP 1 and SIPE 1, and MOPP 4 and SIPE 4 with no cooling (in both environments) . Core temperature, skin temperature, heat storage, and heart rate were lower in SIPE 4 MCC than in MOPP 4; while evaporative cooling was greater in SIPE 4 MCC than in MOPP 4. Three volunteers completed the 4-hour tests in SIPE 4 MCC with similar advantageous trends apparent from the cooling. It is concluded that the SIPE clothing did not increase thermal strain compared to equivalent MOPP levels, and MCC, (although increasing uniform weight by approximately 10 kg) reduced thermal strain at 30.0 deg Celsius.

The "Seiran" was specifically designed for use aboard the submarines and could carry an bomb at . To fit inside the narrow confines of the hangar, the floats were removed and stowed, the wings rotated 90 degrees and folded backward hydraulically against the fuselage, the horizontal stabilizers folded down and the top of the vertical stabilizer folded over so the overall forward profile of the aircraft was within the diameter of its propeller. When deployed for flight, the aircraft had a wingspan of and a length of . A crew of four could prepare and launch all three in 30 minutes (or 15 minutes if the planes' pontoons were not first attached, which would make recovery impossible). As the "Seiran" would normally be launched at night, parts and areas of the plane were coated with luminescent paint to ease assembly in the dark.

The silent 16 mm format was initially aimed at the home enthusiast, but by the 1930s it had begun to make inroads into the educational market. The addition of optical sound tracks and, most notably, Kodachrome in 1935, gave an enormous boost to its popularity. The format was used extensively during World War II, and there was a huge expansion of 16 mm professional filmmaking in the post-war years. Films for government, business, medical and industrial clients created a large network of 16 mm professional filmmakers and related service industries in the 1950s and 1960s. The advent of television production also enhanced the use of 16 mm film, initially for its advantage of cost and portability over 35 mm. At first used as a news-gathering format, the 16 mm format was also used to create television programming shot outside the confines of the more rigid television studio production sets. The home movie market gradually switched to the even less expensive 8 mm and Super 8 mm film formats.

Ion-beam sputtering (IBS) is a method in which the target is external to the ion source. A source can work without any magnetic field like in a hot filament ionization gauge. In a Kaufman source ions are generated by collisions with electrons that are confined by a magnetic field as in a magnetron. They are then accelerated by the electric field emanating from a grid toward a target. As the ions leave the source they are neutralized by electrons from a second external filament. IBS has an advantage in that the energy and flux of ions can be controlled independently. Since the flux that strikes the target is composed of neutral atoms, either insulating or conducting targets can be sputtered. IBS has found application in the manufacture of thin-film heads for disk drives. A pressure gradient between the ion source and the sample chamber is generated by placing the gas inlet at the source and shooting through a tube into the sample chamber. This saves gas and reduces contamination in UHV applications. The principal drawback of IBS is the large amount of maintenance required to keep the ion source operating.

Since 1994 Larhammar has been a professor of molecular biology at Uppsala University where he has supervised 22 students to a PhD degree. His research focuses on three lines of research: clarifying the evolution of the mechanisms for long-term memory, resolving the evolution important gene families in vertebrates, and investigating G protein-coupled receptors which make them bind to and respond to, or reject, certain ligands. Using zebrafish, Larhammar explores the localization and functions of the memory proteins. His team works on discovering at what point new functions rose and how they have changed over the course of evolution, especially in gene families that include neuropeptides, G-protein-coupled receptors, ion channels, and genes involved in vision.

In the United States, radiation oncologists undergo four years of residency (in addition to an internship), which is more dedicated to oncology training than any other medical specialty. During the four years of post-graduate training, residents learn about clinical oncology, the physics and biology of ionizing radiation, and the treatment of cancer patients with radiation. After completion of this training, a radiation oncologist may undergo certification by the American Board of Radiology (ABR). Board certification includes three written tests and an oral examination which is given only once per year. The written tests include separate exams in radiation physics, and radiobiology, clinical oncology, which is followed by an eight-part oral examination given in the late spring one year into practice. Successfully passing these tests leads to the granting of a time-limited board certification. Recertification is obtained via a series of continuing medical education and practice qualifications including a written exam, clinical practice parameter evaluation, continuing medical education credits, and meeting community practice standards.

In 1923, the French physicist Louis de Broglie put forward his theory of matter waves by stating that particles can exhibit wave characteristics and vice versa. This theory was for a single particle and derived from special relativity theory. Building on de Broglie's approach, modern quantum mechanics was born in 1925, when the German physicists Werner Heisenberg, Max Born, and Pascual Jordan developed matrix mechanics and the Austrian physicist Erwin Schrödinger invented wave mechanics and the non-relativistic Schrödinger equation as an approximation of the generalised case of de Broglie's theory. Schrödinger subsequently showed that the two approaches were equivalent. The first applications of quantum mechanics to physical systems were the algebraic determination of the hydrogen spectrum by Wolfgang Pauli and the treatment of diatomic molecules by Lucy Mensing.

The main driver of Jupiter's magnetosphere is the planet's rotation. In this respect Jupiter is similar to a device called a Unipolar generator. When Jupiter rotates, its ionosphere moves relatively to the dipole magnetic field of the planet. Because the dipole magnetic moment points in the direction of the rotation, the Lorentz force, which appears as a result of this motion, drives negatively charged electrons to the poles, while positively charged ions are pushed towards the equator. As a result, the poles become negatively charged and the regions closer to the equator become positively charged. Since the magnetosphere of Jupiter is filled with highly conductive plasma, the electrical circuit is closed through it. A current called the direct current flows along the magnetic field lines from the ionosphere to the equatorial plasma sheet. This current then flows radially away from the planet within the equatorial plasma sheet and finally returns to the planetary ionosphere from the outer reaches of the magnetosphere along the field lines connected to the poles. The currents that flow along the magnetic field lines are generally called field-aligned or Birkeland currents. The radial current interacts with the planetary magnetic field, and the resulting Lorentz force accelerates the magnetospheric plasma in the direction of planetary rotation. This is the main mechanism that maintains co-rotation of the plasma in Jupiter's magnetosphere.

He moved to the United States in 1946 and taught at the University of Notre Dame from 1948. In 1972 he moved to be the W.R. Kenan, Jr. Professor of Chemistry at the University of North Carolina at Chapel Hill until his retirement in 1993. Eliel was elected a Fellow of the American Academy of Arts and Sciences in 1980. In 1981, Eliel became a founding member of the World Cultural Council. He served as president of the American Chemical Society in 1992. In 1995 he received the George C. Pimentel Award in Chemical Education, and in 1996 he was awarded the Priestley Medal of the American Chemical Society. He died in Chapel Hill, North Carolina.

The Urban Aeronautics X-Hawk is a proposed flying car designed by Rafi Yoeli in Yavne, Israel, being built by Metro Skyways Ltd., a subsidiary of Yoeli's privately held company, Urban Aeronautics. The firm claims to have flown the car to a height of , and that greater heights are possible. The X-Hawk and its smaller unmanned version, the Tactical Robotics Cormorant, would be used in search and rescue operations where a helicopter would be useless, or at least very dangerous, such as evacuating people from the upper stories of burning buildings, or delivering and extracting police and soldiers while very close to structures, narrow streets, and confined spaces, with a projected size similar to that of a large van.

Evidence rapidly accumulated to show that natural selection was responsible. Using a method invented by L'Héritier and Teissier, Dobzhansky bred populations in "population cages", which enabled feeding, breeding and sampling whilst preventing escape. This had the benefit of eliminating migration as a possible explanation of the results. Stocks containing inversions at a known initial frequency can be maintained in controlled conditions. It was found that the various chromosome types do not fluctuate at random, as they would if selectively neutral, but adjust to certain frequencies at which they become stabilised. By the time Dobzhansky published the third edition of his book in 1951 he was persuaded that the chromosome morphs were being maintained in the population by the selective advantage of the heterozygotes, as with most polymorphisms.

The rise of the personal computer industry in the early 1980s created a new common practice among both consumers and businesses of adopting "bleeding edge" communications technology even if it was not yet standardized. Thus, standards organizations had to put forth standards much faster, or find themselves ratifying de facto standards after the fact. One of the most prominent examples of this was the Open Document Architecture project, which began in 1985 when a profusion of software firms around the world were still furiously competing to shape the future of the electronic office, and was completed in 1999 long after Microsoft Office's then-secret binary file formats had become established as the global de facto standard.

Structure mapping, originally proposed by Dedre Gentner, is a theory in psychology that describes the psychological processes involved in reasoning through and learning from analogies. More specifically, this theory aims to describe how familiar knowledge, or knowledge about a base domain, can be used to inform an individual's understanding of a less familiar idea, or a target domain. According to this theory, individuals view their knowledge of domains as interconnected structures. In other words, a domain is viewed as consisting of objects, the object's properties, and the relationships that characterize how objects and their properties interact. The process of analogy then involves recognizing similar structures between the two domains, inferring further similarity in structure by mapping additional relationships of a base domain to the target domain, and then checking those inferences against existing knowledge of the target domain. In general, it has been found that people prefer analogies where the two systems have a deep degree of correspondence (e.g. relationships across the domains correspond as opposed to just the objects across domains corresponding) when attempting to draw inferences between the systems. This is also known as the systematicity principle.

Throughout its operation, Davis–Besse has been the site of several safety incidents that affected the plant's operation. According to the Nuclear Regulatory Commission (NRC), Davis–Besse has been the source of two of the top five most dangerous nuclear incidents in the United States since 1979. The most severe occurring in March 2002, when maintenance workers discovered corrosion had eaten a football-sized hole into the reactor vessel head. The NRC kept Davis–Besse shut down until March 2004, so that FirstEnergy was able to perform all the necessary maintenance for safe operations. The NRC imposed an over $5 million fine, its largest fine ever to a nuclear power plant, against FirstEnergy for the actions that led to the corrosion. The company paid an additional $28 million in fines under a settlement with the United States Department of Justice (DOJ).

Mortimer qualified for six women's SM10 events at the 2012 London Paralympics—the 200-metre individual medley, 4 × 100 m freestyle relay 34pts, 4 × 100 m medley relay, 50- and 100-metre freestyle and 100-metre backstroke—and expectations for her were high. On August 30, the first day of the competition, Sophie Pascoe of New Zealand won the SM10 200-metre individual medley; Mortimer took the silver medal. For a half-hour before the competition, Mortimer was "bawling her eyes out"; she told The Canadian Press, "[Being] here and meeting all these people made me realize I am so incredibly grateful for the experience I’ve had as a result of my accident. I don’t know if this was part of the journey I was supposed to walk in life but I wouldn’t take it back for the world". The next day, she won the S10 50-metre freestyle gold medal in a record time of 28.10 seconds. Mortimer's time was .07 second faster than her April Trials record, and .14 second faster than Pascoe's time; she went into the race "a bit annoyed" and "mad at anyone who was going to take it from me".

In December 2014, following a request for information, the bulk of the MMF member states entered negotiations with Airbus to procure an A330 MRTT fleet to be owned by NATO while the Organisation for Joint Armament Cooperation (OCCAR) and the NATO Support and Procurement Agency would support the procurement process. This was accompanied by a request for proposals sent by OCCAR to Airbus for two MRTTs with options for six more; only the Netherlands and Luxembourg were full MMF members at this point. It was decided to base these MRTTs at Eindhoven Air Base, which has noise clearance to operate up to eight MRTTs. In July 2016, the Netherlands and Luxembourg jointly ordered the first two MRTTs under the MMF programme, the first scheduled for delivery by 2020. In June 2017, Germany and Norway became MMF members, pledging to order five more MRTTs plus options for a further four. On 26 September 2017, Airbus announced receipt of OCCAR's firm order for five additional tankers.

Since their discovery in 1873 there has been considerable debate about their origin. Three theories were dominant: from 1949 to 1970 the connective tissue origin was popular, which stated that osteoclasts and osteoblasts are of the same lineage, and osteoblasts fuse together to form osteoclasts. After years of controversy it is now clear that these cells develop from the self fusion of macrophages. It was in the beginning of 1980 that the monocyte phagocytic system was recognized as precursor of osteoclasts. Osteoclast formation requires the presence of RANKL (receptor activator of nuclear factor κβ ligand) and M-CSF (Macrophage colony-stimulating factor). These membrane-bound proteins are produced by neighbouring stromal cells and osteoblasts, thus requiring direct contact between these cells and osteoclast precursors.

Neurexins (NRXN) are a family of presynaptic cell adhesion proteins that have roles in connecting neurons at the synapse. They are located mostly on the presynaptic membrane and contain a single transmembrane domain. The extracellular domain interacts with proteins in the synaptic cleft, most notably neuroligin, while the intracellular cytoplasmic portion interacts with proteins associated with exocytosis. Neurexin and neuroligin "shake hands," resulting in the connection between the two neurons and the production of a synapse. Neurexins mediate signaling across the synapse, and influence the properties of neural networks by synapse specificity. Neurexins were discovered as receptors for α-latrotoxin, a vertebrate-specific toxin in black widow spider venom that binds to presynaptic receptors and induces massive neurotransmitter release. In humans, alterations in genes encoding neurexins are implicated in autism and other cognitive diseases, such as Tourette syndrome and schizophrenia.

Studies suggest that Rb repression of the E2F family of transcription factors regulates the G to G transition just as it does the G to S transition. Activating E2F complexes are associated with the recruitment of histone acetyltransferases, which activate gene expression necessary for G entry, while E2F4 complexes recruit histone deacetylases, which repress gene expression. Phosphorylation of Rb by Cdk complexes allows its dissociation from E2F transcription factors and the subsequent expression of genes necessary for G exit. Other members of the Rb pocket protein family, such as p107 and p130, have also been found to be involved in G arrest. p130 levels are elevated in G and have been found to associate with E2F-4 complexes to repress transcription of E2F target genes. Meanwhile, p107 has been found to rescue the cell arrest phenotype after loss of Rb even though p107 is expressed at comparatively low levels in G cells. Taken together, these findings suggest that Rb repression of E2F transcription factors promotes cell arrest while phosphorylation of Rb leads to G exit via derepression of E2F target genes. In addition to its regulation of E2F, Rb has also been shown to suppress RNA polymerase I and RNA polymerase III, which are involved in rRNA synthesis. Thus, phosphorylation of Rb also allows activation of rRNA synthesis, which is crucial for protein synthesis upon entry into G.

Johns, Schmader, and Martens (2005) conducted a study in which they examined the effect of teaching stereotype threat as a means of improving women's math performance. The researchers concluded that women tended to perform worse than men when problems were described as math equations. However, women did not differ from men when the test sequence was described as problem solving or in a condition in which they learned about stereotype threats. This research has practical implications. The results suggested that teaching students about stereotype threat could offer a practical means of reducing its detrimental effects and lead to an improvement in a girl's performance and mathematical ability, leading the researchers to conclude that educating female teachers about stereotype threat can reduce its negative effects in the classroom.

European sources find it more certain that dental infections drive systemic diseases, at least by driving systemic inflammation, and probably, among other immunologic mechanisms, by molecular mimicry resulting in antigenic crossreaction with host biomolecules, while some seemingly find progressive invasion of local tissues compatible with focal infection theory. Acknowledging that beyond epidemiological associations, successful intervention is needed to establish causality, they emphasize that biological explanation is needed atop both, and the biological aspect is thoroughly established already, such that general healthcare, as for cardiovascular disease, must address prevalent periodontal disease, a stance matched in Indian literature. Thus, there has emerged the concept "periodontal medicine".

A key problem was that the customer might only have a single twisted pair line to the location of the handset, so the solution used in T1 with separate upstream and downstream connections was not universally available. With analog connections, the solution was to use echo cancellation, but at the much higher bandwidth of the new concept, this would not be so simple. A debate broke out between teams worldwide about the best solution to this problem; some promoted newer versions of echo cancellation, while others preferred the "ping pong" concept where the direction of data would rapidly switch the line from send to receive at such a high rate it would not be noticeable to the user. John Cioffi had recently demonstrated echo cancellation would work at these speeds, and further suggested that they should consider moving directly to 1.5 Mbit/s performance using this concept. The suggestion was literally laughed off the table (His boss told him to "sit down and shut up") but the echo cancellation concept was taken up by Joe Lechleider eventually came to win the debate.

Hahn was fascinated by chemistry and spent years conducting amateur chemistry experiments, which sometimes caused small explosions and other mishaps. He was inspired in part by reading "The Golden Book of Chemistry Experiments" and tried to collect samples of every element in the periodic table, including the radioactive ones. He later received a merit badge in Atomic Energy and became fascinated with the idea of creating a breeder reactor in his home. Hahn diligently amassed radioactive material by collecting small amounts from household products, such as americium from smoke detectors, thorium from camping lantern mantles, radium from clocks, and tritium from gunsights. His "reactor" was a bored-out block of lead, and he used lithium from $1,000 worth of purchased batteries to purify the thorium ash using a Bunsen burner.

Additional medications that are being considered for prevention but require further research to determine efficacy and treatment guidelines include acetazolamide, salmeterol, tadalafil (and other PDE5 inhibitors), and dexamethasone. Acetazolamide has proven to be clinically effective, but formal studies are lacking. Salmeterol is considered an adjunctive therapy to nifedipine, though only in highly susceptible climbers with clearly demonstrated recurrence of HAPE. Tadalafil was found to be effective at preventing HAPE in HAPE-s individuals during rapid ascent, but optimal dosing and frequency has yet to be established. Use of dexamethasone is currently indicated for the treatment of moderate-to-severe acute mountain sickness, as well as high-altitude cerebral edema. It has also been found to prevent HAPE, but its routine use is not yet recommended.

Through the whole Siberian prehistoric period from the Neolithic until the Iron Age, there are a very limited range of ceramic types. The vast majority of ceramic finds are round bulbous vessels, often with folded edges. In the Neolithic they mostly had concave bases, while later flat bases became more common. In the eastern part of the west Siberian forest steppe, on the Ob, Irtysh and Yenissei, decoration consisted of comb patterns, puncture rows and dimples, arranged in long series or fields (right image). In the course of the dramatic growth of the Andronovo culture in the middle Bronze Age, another type spread through the region. Examples of it are decorated with meander bands, herringbone patterns and triangles (left image). These ceramic types endured even into the Iron Age in west Siberia, yet a stark decline in decoration is observable, contemporary with the entrance of the Scythian and Hunnic Sarmatian nomads. This applies even to the nomadic cultures themselves.

The genus "Mycobacterium" is a slow growing bacteria, made up of small rods that are slightly curved or straight, and are considered to be gram positive. Some mycobacteria are free-living saprophytes, but many are pathogens that cause disease in animals and humans. "Mycobacterium bovis" causes tuberculosis in cattle. Since tuberculosis can be spread to humans, milk is pasteurized to kill any of the bacteria. The Mycobacteria species that causes tuberculosis (TB) in humans is "Mycobacterium tuberculosis", which is an airborne bacterium that typically infects the human lungs. Testing for TB includes blood testing, skin tests, and chest X-rays. When looking at the smears for TB, it is stained using an acid-fast stain. These acid-fast organisms like "Mycobacterium" contain large amounts of lipid substances within their cell walls called mycolic acids. These acids resist staining by ordinary methods such as a Gram stain. It can also be used to stain a few other bacteria, such as "Nocardia". The reagents used for Ziehl–Neelsen staining are carbol fuchsin, acid alcohol, and methylene blue. Acid-fast bacilli are bright red after staining.

They proposed a large engine to provide 2,500 hp initially, with room for growth upwards. Instead of using advanced features such as sleeve valves for improved RPM, they instead decided to use a larger number of "normal sized" cylinders in a V-16 arrangement. The Army was interested, and sent them a development contract tender on June 22, 1940, to which Chrysler responded on July 2.

A quantitative imaging biomarkers (QIB) is "an objective characteristic derived from an in vivo image measured on a ratio or interval scale as indicators of normal biological processes, pathogenic processes or a response to a therapeutic intervention". advantage of QIB's over qualitative imaging biomarkers is that they are better suited to be used for follow-up of patients or in clinical trials. Examples of a frequently used QIB are the RECIST criteria, measuring the evolution in tumor size to assess treatment response for patients with cancer, the Nuchal scan used for prenatal screening, or the assessment of lesion load and brain atrophy for patients with multiple sclerosis.

Periglaciation became a distinct subject within the study of geology after Walery Łoziński, a Polish geologist, introduced the term in 1909. Łoziński drew upon the early work of Johan Gunnar Andersson. According to Alfred Jahn, his introduction of his work at the 1910 International Geological Congress held in Stockholm caused significant discussion. In the field trip to Svalbard that followed the congress participants were able to observe the phenomena reported by Łoziński, directly. Łoziński published his contribution to the congress in 1912. From 1950 to 1970, periglacial geomorphology developed chiefly as a subdiscipline of climatic geomorphology that was current in Europe at the time. The journal "Biuletyn Peryglacjalny", established in 1954 by Jan Dylik, was important for the consolidation of the discipline.

Educators have shown some interest and described projects and experiences with transformation geometry for children from kindergarten to high school. In the case of very young age children, in order to avoid introducing new terminology and to make links with students' everyday experience with concrete objects, it was sometimes recommended to use words they are familiar with, like "flips" for line reflections, "slides" for translations, and "turns" for rotations, although these are not precise mathematical language. In some proposals, students start by performing with concrete objects before they perform the abstract transformations via their definitions of a mapping of each point of the figure.

An All-American team is an honorary sports team composed of the best amateur players of a specific season for each team position—who in turn are given the honorific "All-America" and typically referred to as "All-American athletes", or simply "All-Americans". Although the honorees generally do not compete together as a unit, the term is used in U.S. team sports to refer to players who are selected by members of the national media. Walter Camp selected the first All-America team in the early days of American football in 1889. The 2010 NCAA Men's Basketball All-Americans are honorary lists that include All-American selections from the Associated Press (AP), the United States Basketball Writers Association (USBWA), the "Sporting News" (TSN), and the National Association of Basketball Coaches (NABC) for the 2009–10 NCAA Division I men's basketball season. All selectors choose at least a first and second 5-man team. The NABC and AP choose third teams, and TSN chooses third, fourth and fifth teams, while AP also lists honorable mention selections.

"Semantic" retrieval starts with a user making a request like "find pictures of Abraham Lincoln". This type of open-ended task is very difficult for computers to perform - Lincoln may not always be facing the camera or in the same pose. Many CBIR systems therefore generally make use of lower-level features like texture, color, and shape. These features are either used in combination with interfaces that allow easier input of the criteria or with databases that have already been trained to match features (such as faces, fingerprints, or shape matching). However, in general, image retrieval requires human feedback in order to identify higher-level concepts.

Petrochemicals are predominantly made in a few manufacturing locations around the world, for example in Jubail & Yanbu Industrial Cities in Saudi Arabia, Texas & Louisiana in the US, in Teesside in the Northeast of England in the United Kingdom, in Rotterdam in the Netherlands, in Jamnagar, Dahej in Gujarat, India and in Singapore. Not all of the petrochemical or commodity chemical materials produced by the chemical industry are made in one single location but groups of related materials are often made in adjacent manufacturing plants to induce industrial symbiosis as well as material and utility efficiency and other economies of scale. This is known in chemical engineering terminology as integrated manufacturing. Specialty and fine chemical companies are sometimes found in similar manufacturing locations as petrochemicals but, in most cases, they do not need the same level of large-scale infrastructure (e.g., pipelines, storage, ports, and power, etc.) and therefore can be found in multi-sector business parks.

OTDR was developed more than 20 years ago and has become the industry standard for telecom loss measurements which detects the—compared to Raman signal very dominant—Rayleigh backscattering signals. The principle for OTDR is quite simple and is very similar to the time of flight measurement used for radar. Essentially a narrow laser pulse generated either by semiconductor or solid state lasers is sent into the fibre and the backscattered light is analysed. From the time it takes the backscattered light to return to the detection unit it is possible to locate the location of the temperature event.

Swamidass published "The Genealogical Adam and Eve: The Surprising Science of Universal Ancestry" in 2019 based on implications of recent universal genealogical ancestry regarding the theology of the image of God, the fall, and people outside the garden. The appendix includes Swamidass' work "The Resurrection, Evidence, and The Scientist", which discusses his reasons for belief in the resurrection of Jesus. In his interview with “BibleProject Podcast”, he discussed the differences between genealogical ancestry and genetic ancestry, and explored the conflict that exists between evolutionary science and creationism. Furthermore, he stated "The genealogical account does not prove [Adam and Eve’s existence], but it’s impossible to disprove the existence of such a couple 6,000 years ago." Anjeanette Roberts praised Swamidass’ work and stated that in his book the emphasis on "genealogical ancestry is so clearly biblical that its long-term absence in evangelical conversations about human origins is shocking" and the work also helps to remove "the enmity and barriers that divide scientists, theologians, exegetes, evolutionists, and creationists." Nathan H. Lents thought the book's "bold attempt" to find a place for Adam and Eve within the scientific understanding of human ancestry might help reconcile evangelicals to evolutionary science, and science in general, but thought it unlikely to persuade scientists of a role for the "Genesis" narrative in human origins.

The 18-month-long trial tested a total of 28 designs and finally solved all of the existing problems. However, the Chinese microelectronics industry was not capable to produce the passive acoustic homing guidance according to the original plan, but due to the urgent need, the original plan changed one last time with unguided version was pressed into service as Yu (鱼) -1 (in September 1971), while the passive acoustic homing guided version was named Yu-1 Jia (鱼-1甲), sometimes also known as Yu-1G, which would take years to complete.

Any inherent errors in early pendulum clocks were smaller than other errors caused by factors such as temperature variation. In 1729 the Yorkshire carpenter and self-taught clockmaker John Harrison invented the gridiron pendulum, which used at least three metals of different lengths and expansion properties, connected so as to maintain the overall length of the pendulum when it is heated or cooled by its surroundings. In 1781 the clockmaker George Graham compensated for temperature variation in an iron pendulum by using a bob made from a glass jar of mercury—a liquid metal at room temperature that expands faster than glass. More accurate versions of this innovation contained the mercury in thinner iron jars to make them more responsive. This type of temperature compensating pendulum was improved still further when the mercury was contained within the rod itself, which allowed the two metals to be thermally coupled more tightly. In 1895, the invention of invar, an alloy made from iron and nickel that expands very little, largely eliminated the need for earlier inventions designed to compensate for the variation in temperature.

Similar to text-based sentiment analysis, multimodal sentiment analysis can be applied in the development of different forms of recommender systems such as in the analysis of user-generated videos of movie reviews and general product reviews, to predict the sentiments of customers, and subsequently create product or service recommendations. Multimodal sentiment analysis also plays an important role in the advancement of virtual assistants through the application of natural language processing (NLP) and machine learning techniques. In the healthcare domain, multimodal sentiment analysis can be utilized to detect certain medical conditions such as stress, anxiety, or depression. Multimodal sentiment analysis can also be applied in understanding the sentiments contained in video news programs, which is considered as a complicated and challenging domain, as sentiments expressed by reporters tend to be less obvious or neutral.

It is not possible to completely avoid all discrepant messages. When exposure to a dissonant message has occurred, the phenomenon of selective perception often follows. This process simply means that people skew their perceptions to coincide with what they desire (Johnson-Cartee & Copeland, 1997). Perception is subjective and dependent on several factors; one factor, for example, is media type. Prior research indicates that people who actively process television news tend to engage in more individualized explanations of an event as opposed to those active processors of newspapers (McLeod, Kosicki, & McLeod, 2002). The selective perception discussed here, however, is done in order to reduce dissonance with previously held beliefs (Wheeless, 1974). Several communication theories use this assumption of skewed perception as their basis (i.e., hostile media phenomenon, third-person effect).

Scintillation, meaning rapid modification, in radio waves due to the small scale structures in the ionosphere, known as ionospheric scintillation, was observed as early as 1951 by Antony Hewish, and he then reported irregularities in radiation received during an observation of a bright radio source in Taurus in 1954. Hewish considered various possibilities, and suggested that irregularities in the solar corona would cause scattering by refraction and could produce the irregularities he observed. A decade later, while making astrometric observations of several bright sources of celestial radio waves using a radio interferometer, Hewish and two collaborators reported "unusual fluctuations of intensity" in a few of the sources. The data strongly supported the notion that the fluctuations resulted from irregularities in the density of the plasma associated with the solar wind, which the authors called interplanetary scintillation, and is recognized as the "discovery of the interplanetary scintillation phenomenon."

One of the earliest electronic photocomposition systems was introduced by Fairchild Semiconductor. The typesetter typed a line of text on a Fairchild keyboard that had no display. To verify correct content of the line it was typed a second time. If the two lines were identical a bell rang and the machine produced a punched paper tape corresponding to the text. With the completion of a block of lines the typesetter fed the corresponding paper tapes into a phototypesetting device that mechanically set type outlines printed on glass sheets into place for exposure onto a negative film. Photosensitive paper was exposed to light through the negative film, resulting in a column of black type on white paper, or a galley. The galley was then cut up and used to create a mechanical drawing or paste up of a whole page. A large film negative of the page is shot and used to make plates for offset printing.

Product service systems (PSS) are sets of marketable products and services that work together to fulfill a user's needs. This approach is a result of firms realizing that services in combination with products can provide higher profits and customer satisfaction then simply selling products alone. Firms that use PSS work to find ways to maximize the use of their product throughout its lifetime, using services to supplement its usage. PSS has been seen to have smaller environmental impact than traditional business models, as the focus on services has led to a decrease in material production and consumption. This applies to life cycle thinking because it involves looking at the life-cycle cost of a product (i.e. maintenance and storage costs) for a consumer and reducing that cost by providing services with the purchased good.

From several studies involving cases of "P. oryzihabitans", research reveals that there is a close relationship between infection, underlying disease, and the presence of catheters in patients. This means that infections occur most in people that have debilitating disease and have artificial material located in their bodies. Along with catheters, "P. oryzihabitans" are most commonly found at sites involved with respiratory equipment and devices for continuous ambulatory dialysis, and these bacteria can spread through contaminated fluids and unsterilized or defiled medical tools. If this is the case, it is important for hygiene to be maintained internally and externally to help stop the spread of the bacteria and prevent infectious disease. Infections can be either nosocomially acquired, which means that the bacteria originated during a patient's duration in the hospital forty-eight hours after admittance, or they are community-acquired, which means that the patient had evidence of infection before admission or during the first forty-eight hours in the hospital.

While some sources say that an individual's style of throwing or the type of pitches that they throw are the most important determinant of their likelihood to sustain an injury, the results of a 2002 study suggest that the total number of pitches thrown is the greatest determinant. A 2002 study examined the throwing volume, pitch type and throwing mechanics of 426 pitchers aged 9 to 14 for one year. Compared to pitchers who threw 200 or fewer pitches in a season, those who threw 201–400, 401–600, 601–800 and 800+ pitches faced an increased risk of 63%, 181%, 234% and 161% respectively. The types of pitches thrown showed a smaller effect; throwing a slider was associated with an 86% increased chance of elbow injury while throwing a curveball was associated with an increase in pain. There was only a weak correlation between throwing mechanics perceived as bad and injury-prone.

Despite the potential retirement of the Block 30 fleet due to low reliability, low mission readiness, and high costs, the USAF released a pre-solicitation notice in September 2013 for Lot 12 aircraft. In planning the USAF's FY 2015 budget, the Pentagon reversed its previous decision, shifting $3 billion from the U-2 to the RQ-4 Block 30, which had become more competitive with the U-2 due to increased flying hours. Factors such as cost per flight hour (CPFH), information gathering rates, mission readiness, adverse weather operational capability, distance to targets, and onboard power still favored the U-2.

What sets connectivism apart from theories such as constructivism is the view that "learning (defined as actionable knowledge) can reside outside of ourselves (within an organization or a database), is focused on connecting specialized information sets, and the connections that enable us to learn more are more important than our current state of knowing". Connectivism sees knowledge as a network and learning as a process of pattern recognition. Connectivism has similarities with Vygotsky's zone of proximal development (ZPD) and Engeström's activity theory. The phrase "a learning theory for the digital age" indicates the emphasis that connectivism gives to technology's effect on how people live, communicate, and learn. Connectivism is an integration of principles related to chaos, network, complexity, and self-organization theories.

Where the Model 700 differs from classical delta-sigma modulation is in its replacement of the single integrator with a complex system of comparators and high-order linear prediction filters. This was done in order to reduce the quantization error, and is accomplished in part by changing the effective "step size" of the encoder based on previously recorded information. (Thereby increasing or decreasing the slew rate.) The system also has two analog pre-processing steps which compress the input signal in both the amplitude and frequency domain, in order to more closely match the abilities of the encoder. This compression is done adaptively based on previously encoded signal, and is reversed on the decoding end.

In 1928, Medawar went to Marlborough College in Marlborough, Wiltshire. He hated the college because "they were critical and querulous at the same time, wondering what kind of person a Lebanese was—something foreign you can be sure". And also because of its preference on sports, in which he was weak. An experience of bullying and racism made him feel the rest of his life "resentful and disgusted at the manners and mores of [Marlborough's] essentially tribal institution," and likened it to the training schools for the Nazi SS as all "founded upon the twin pillars of sex and sadism." His proudest moments at the college were with his teacher Ashley Gordon Lowndes, to whom he credited the beginning of his career in biology. He recognised Lowndes as barely literate but "a very, very good biology teacher". Lowndes had taught eminent biologists including John Z. Young and Richard Julius Pumphrey. Yet Medawar was inherently weak in dissection and was constantly irked by their dictum: "Bloody foolish is the boy whose drawing of his dissection differs in any way whatsoever from the diagram in the textbook."

The concerto had a disastrous premiere, at the opening concert of the London Symphony Orchestra's 1919–20 season on 27 October 1919. Apart from the concerto, which the composer conducted, the rest of the programme was conducted by Albert Coates, who overran his rehearsal time at the expense of Elgar's. Lady Elgar wrote, "that brutal selfish ill-mannered bounder ... that brute Coates went on rehearsing." The critic of "The Observer", Ernest Newman, wrote, "There have been rumours about during the week of inadequate rehearsal. Whatever the explanation, the sad fact remains that never, in all probability, has so great an orchestra made so lamentable an exhibition of itself. ... The work itself is lovely stuff, very simple – that pregnant simplicity that has come upon Elgar's music in the last couple of years – but with a profound wisdom and beauty underlying its simplicity." Elgar attached no blame to his soloist, Felix Salmond, who played for him again later. Elgar said that if it had not been for Salmond's diligent work in preparing the piece, he would have withdrawn it from the concert entirely.

Numerous proteins are utilized in PNP synthesis. They are often sourced naturally from animal and plant sources. Accordingly, generally shared advantages of animal proteins include high biocompatibility, biodegradability, non-immunogenicity, drug loading efficiency, cell uptake, and easy and cost-effective production. Tables 2–4 below compile the common proteins used in PNP synthesis. The types of PNPs share similar physical properties such as high biocompatibility, non-immunogenicity, high drug efficiency, high biodegradability, and high cell uptake. Due to the abundance of proteins necessary for proper bodily function, the body has developed processes to update proteins into tissues and cells. PNPs take advantage of these natural processes to enhance their cellular uptake. This abundance and the natural sourcing subsequent purification of the proteins also reduce the immunogenic responses and produce low toxicity levels in the body. As the PNPs are degraded, the tissues assimilate the amino acids into energy or protein production.

In "The Orrery", all the subjects have been identified apart from the philosopher, who has physical similarities to Isaac Newton but differs enough to make positive identification impossible. Nicolson detects the strong influence of Frye throughout the picture. Particularly striking is the similarity between Frye's mezzotint "Portrait of a Young Man" of 1760–1761 and the figure of the boy with his head cocked staring intently at the bird. In 1977, Michael Wynne published one of Frye's chalk drawings from around 1760, "An old man leaning on a staff", which is so similar to the observer in the right foreground in Wright's picture to make it impossible that Wright had not seen it. There are other hints of Frye's style in the painting: even the figure of the natural philosopher has touches of Frye's "Figure with Candle". Though Henry Fuseli would later also develop on the style of Frye's work there is no evidence of him having painted anything similar until the early 1780s. So, although he had already been in England at the time the "Air Pump" was produced, it is unlikely that he was an influence on Wright.

One proposal to improve research for treatment in aggressive lymphoma is to use canines as model animals. Canine lymphoma prevalence has been increasing over the years similar to the incidence of human lymphoma cases. Lymphoma represents the most frequent hematopoietic cancer in dogs with canine non-Hodgkin lymphoma (cNHL) having the highest incidence at 83% of all hematopoietic cancers. In addition to this diffuse large B-cell lymphoma is the most commonly seen subtype of NHL in both species. The advantages of using canines as model animals include spontaneous disease occurring without an isogenic background or genetic engineering; chronology of disease adapted to lifespan; shared environmental and societal status that allows dogs to be treated as "patients", while at the same time being able to ethically explore translational innovations that are not possible in human subjects; and organization of dogs into breeds with relatively homogeneous genetic backgrounds and distinct predisposition for lymphomas. In addition to this, there have also been studies that suggest that breed type might influence disease progression and response to therapy which is very promising for human therapeutic research.

Critical responses to relativity were also expressed by proponents of neo-Kantianism (Paul Natorp, Bruno Bauch etc.), and phenomenology (Oskar Becker, Moritz Geiger etc.). While some of them only rejected the philosophical consequences, others rejected also the physical consequences of the theory. Einstein was criticized for violating Immanuel Kant's categoric scheme, "i.e.", it was claimed that space-time curvature caused by matter and energy is impossible, since matter and energy already require the concepts of space and time. Also the three-dimensionality of space, Euclidean geometry, and the existence of absolute simultaneity were claimed to be necessary for the understanding of the world; none of them can possibly be altered by empirical findings. By moving all those concepts into a metaphysical area, any form of criticism of Kantianism would be prevented. Other pseudo-Kantians like Ernst Cassirer or Hans Reichenbach (1920), tried to modify Kant's philosophy. Subsequently, Reichenbach rejected Kantianism at all and became a proponent of logical positivism.

Ephs can be divided into two subclasses, EphAs and EphBs (encoded by the genetic loci designated "EPHA" and "EPHB" respectively), based on sequence similarity and on their binding affinity for either the glycosylphosphatidylinositol-linked ephrin-A ligands or the transmembrane-bound ephrin-B ligands. Of the 16 Eph receptors (see above) that have been identified in animals, humans are known to express nine EphAs (EphA1-8 and EphA10) and five EphBs (EphB1-4 and EphB6). In general, Ephs of a particular subclass bind preferentially to all ephrins of the corresponding subclass, but have little to no cross-binding to ephrins of the opposing subclass. It has recently been proposed that the intrasubclass specificity of Eph/ephrin binding could be partially attributed to the different binding mechanisms used by EphAs and EphBs. There are exceptions to the intrasubclass binding specificity observed in Ephs, however, as it has recently been shown that ephrin-B3 can bind to and activate EphA4 and that ephrin-A5 can bind to and activate EphB2. EphA/ephrinA interaction typically occur with higher affinity than EphB/ephrin-B interactions which can partially be attributed to the fact that ephrin-As bind via a "lock-and-key" mechanism that requires little conformational change of the EphAs in contrast to EphBs which utilize an "induced fit" mechanism that requires a greater amount of energy to alter the conformation of EphBs to bind to ephrin-Bs.

Following the HLH program cancellation, Allison decided in early 1976 to apply the XT701 engine technology into a new industrial gas turbine product, the 570-K. The industrial engine, which entered production in the late 1970s, was derated to and adapted for marine, gas compressor, and electrical power generation variants. The only major changes made for the 570-K were the elimination of compressor bleed air and replacing the XT701's titanium compressor case with a steel case. The 570-K was then adapted to the 501-M78B demonstration engine, which Lockheed flew on a Grumman Gulfstream II as part of the NASA Propfan Test Assessment Program in the late 1980s. The 501-M78B had the same 13-stage compressor, combustor, 2-stage gas producer turbine, and 2-stage free power turbine used on the XT701 and 570-K, but it was connected through a 6.797 reduction ratio gearbox to a Hamilton Standard single-rotation propfan, containing propfan blades that were swept back 45 degrees at the tips.

In this approach, the second law of thermodynamics is introduced as "Energy spontaneously disperses from being localized to becoming spread out if it is not hindered from doing so," often in the context of common experiences such as a rock falling, a hot frying pan cooling down, iron rusting, air leaving a punctured tyre and ice melting in a warm room. Entropy is then depicted as a sophisticated kind of "before and after" yardstick — measuring how much energy is spread out over time as a result of a process such as heating a system, or how widely spread out the energy is after something happens in comparison with its previous state, in a process such as gas expansion or fluids mixing (at a constant temperature). The equations are explored with reference to the common experiences, with emphasis that in chemistry the energy that entropy measures as dispersing is the internal energy of molecules.

Under UMTRCA, the DOE created UMTRA to decommission 24 uranium mills and dispose of their residual mill tailings. These are typically stored in an engineered disposal cell, described in the 1995 (). designed to reduce groundwater contamination, as well as withstanding precipitation and flood events, withstanding "maximum credible earthquakes", and preferably having a design lifespan of 1000 years. The covers are also designed to substantially reduce radon gas emission. The disposal cells are located at the mill site or within 5 miles, if possible.

Caddisfly larvae can be found in all feeding guilds in freshwater habitats. Most early stage larvae and some late stage ones are collector-gatherers, picking up fragments of organic matter from the benthos. Other species are collector-filterers, sieving organic particles from the water using silken nets, or hairs on their legs. Some species are scrapers, feeding on the film of algae and other periphyton that grows on underwater objects in sunlight. Others are shredder-herbivores, chewing fragments off living plant material while others are shredder-detritivores, gnawing at rotting wood or chewing dead leaves that have been pre-processed by bacteria and fungi; most of the nutrients of the latter group come from consumption of the bacteria and fungi. The predatory species either actively hunt their prey, typically other insects, tiny crustaceans and worms, or lie in wait for unwary invertebrates to come too close. A few species feed opportunistically on dead animals or fish, and some Leptoceridae larvae feed on freshwater sponges.

The Solinst Waterloo Multilevel groundwater monitoring system is a modular MLS designed to collect groundwater data from multiple depths within a single borehole via a series of monitoring ports positioned at specific intervals along 2-inch ID Schedule 80 PVC casing. The various monitoring ports can be connected to a combination of: sampling pumps, transducers, or polyethylene tubes that extend from the ports to the ground surface inside of the PVC casing. The smooth exterior wall of the PVC casing facilitates construction of annular seals between the monitored zones in the borehole via backfilling with alternating layers of sand and bentonite, or using expandable packers manufactured by Solinst. The sections of PVC casing have water-tight joints to prevent hydraulic cross-communication within the well. Depending on the diameter and number of monitoring equipment, the system can have up to 24 ports. The system is described in more detail by Einarson (2006), with additional information provided by Solinst.

Several competing designs were offered, and even more were drawn up prior to reaching prototype stage. All had heavy armour, torsion-bar suspension, wide tracks, and were of welded and cast construction. One of the main competing designs was the SMK, which in its final form had two turrets, mounting one 76.2 mm and one 45 mm weapon. The designers of the SMK independently drew up a single-turreted variant and this received approval at the highest level. Two of these, named after the People's Commissar for Defence, were ordered alongside a single SMK. The smaller hull and single turret enabled the designer to install heavy frontal and turret armour while keeping the weight within manageable limits.

The University of Illinois, originally named "Illinois Industrial University", was one of the 37 universities created under the first Morrill Land-Grant Act, which provided public land for the creation of agricultural and industrial colleges and universities across the United States. Among several cities, Urbana was selected in 1867 as the site for the new school. From the beginning, President John Milton Gregory's desire to establish an institution firmly grounded in the liberal arts tradition was at odds with many state residents and lawmakers who wanted the university to offer classes based solely around "industrial education". The university opened for classes on March 2, 1868, and had two faculty members and 77 students.

Legendre (1786) laid down a method, not entirely satisfactory, for the discrimination of maxima and minima. Isaac Newton and Gottfried Leibniz also gave some early attention to the subject. To this discrimination Vincenzo Brunacci (1810), Carl Friedrich Gauss (1829), Siméon Poisson (1831), Mikhail Ostrogradsky (1834), and Carl Jacobi (1837) have been among the contributors. An important general work is that of Sarrus (1842) which was condensed and improved by Cauchy (1844). Other valuable treatises and memoirs have been written by Strauch (1849), Jellett (1850), Otto Hesse (1857), Alfred Clebsch (1858), and Lewis Buffett Carll (1885), but perhaps the most important work of the century is that of Weierstrass. His celebrated course on the theory is epoch-making, and it may be asserted that he was the first to place it on a firm and unquestionable foundation. The 20th and the 23rd Hilbert problem published in 1900 encouraged further development.

"A Theory of Justice" received criticism from several philosophers. Robert Nozick criticized Rawls' account of distributive justice in his defense of libertarianism, "Anarchy, State, and Utopia" (1974). Allan Bloom, writing in "American Political Science Review" in 1975, noted that "A Theory of Justice" had "attracted more attention in the Anglo-Saxon world than any work of its kind in a generation", attributing its popularity to its being "the most ambitious political project undertaken by a member of the school currently dominant in academic philosophy" and to Rawls' "radical egalitarian interpretation of liberal democracy." Bloom criticized Rawls for failing to account for the existence of natural right in his theory of justice and wrote that Rawls absolutizes social union as the ultimate goal which would conventionalize everything into artifice. Robert Paul Wolff criticized Rawls from a Marxist perspective in "Understanding Rawls: A Critique and Reconstruction of A Theory of Justice" (1977), arguing Rawls offers an apology for the status quo insofar as he constructs justice from existing practice and forecloses the possibility that there may be problems of injustice embedded in capitalist social relations, private property or the market economy.

Australopithecus garhi is a species of australopithecine from the Bouri Formation in the Afar Region of Ethiopia 2.6–2.5 million years ago (mya) during the Early Pleistocene. The first remains were described in 1999 based on several skeletal elements uncovered in the three years preceding. "A. garhi" was originally considered to have been a direct ancestor to "Homo" and the human line, but is now thought to have been an offshoot. Like other australopithecines, "A. garhi" had a brain volume of ; a jaw which jutted out (prognathism); relatively large molars and premolars; adaptations for both walking on two legs (bipedalism) and grasping while climbing (arboreality); and it is possible that, though unclear if, males were larger than females (exhibited sexual dimorphism). One individual, presumed female based on size, may have been tall.

Model-based systems engineering (MBSE), according to the International Council on Systems Engineering (INCOSE), is the "formalized application of modeling to support system requirements, design, analysis, verification and validation activities beginning in the conceptual design phase and continuing throughout development and later life cycle phases." MBSE is a technical approach to systems engineering that focuses on creating and exploiting domain models (aka Chocolate Factory Diagrams) as the primary means of information exchange, rather than on document-based information exchange. MBSE technical approaches are commonly applied to a wide range of industries with complex systems, such as aerospace, defense, rail, automotive, manufacturing, etc.

The spectrometer consists of a suitable scintillator crystal, a photomultiplier tube, and a circuit for measuring the height of the pulses produced by the photomultiplier. The pulses are counted and sorted by their height, producing a x-y plot of scintillator flash brightness vs number of the flashes, which approximates the energy spectrum of the incident radiation, with some additional artifacts. A monochromatic gamma radiation produces a photopeak at its energy. The detector also shows response at the lower energies, caused by Compton scattering, two smaller escape peaks at energies 0.511 and 1.022 MeV below the photopeak for the creation of electron-positron pairs when one or both annihilation photons escape, and a backscatter peak. Higher energies can be measured when two or more photons strike the detector almost simultaneously (pile-up, within the time resolution of the data acquisition chain), appearing as sum peaks with energies up to the value of two or more photopeaks added

In response to the complaints about the definition of the word "function" some have noted that ENCODE did define what it meant and since the scope of ENCODE was seeking biomedically relevant functional elements in the genome, then the conclusion of the project should be interpreted ""as saying that 80 % of the genome is engaging in relevant biochemical activities that are very likely to have causal roles in phenomena deemed relevant to biomedical research."" Ewan Birney, one of the ENCODE researchers, commented that "function" was used pragmatically to mean "specific biochemical activity" which included different classes of assays: RNA, "broad" histone modifications, "narrow" histone modifications, DNaseI hypersensitive sites, Transcription Factor ChIP-seq peaks, DNaseI Footprints, Transcription Factor bound motifs, and Exons.

All compressors have an optimum point relating rotational speed and pressure, with higher compressions requiring higher speeds. Early engines were designed for simplicity, and used a single large compressor spinning at a single speed. Later designs added a second turbine and divided the compressor into low-pressure and high-pressure sections, the latter spinning faster. This "two-spool" design, pioneered on the Bristol Olympus, resulted in increased efficiency. Further increases in efficiency may be realised by adding a third spool, but in practice the added complexity increases maintenance costs to the point of negating any economic benefit. That said, there are several three-spool engines in use, perhaps the most famous being the Rolls-Royce RB211, used on a wide variety of commercial aircraft.

The N-end rule may partially determine the half-life of a protein, and proteins with segments rich in proline, glutamic acid, serine, and threonine (the so-called PEST proteins) have short half-life. Other factors suspected to affect degradation rate include the rate deamination of glutamine and asparagine and oxidation of cystein, histidine, and methionine, the absence of stabilizing ligands, the presence of attached carbohydrate or phosphate groups, the presence of free α-amino group, the negative charge of protein, and the flexibility and stability of the protein. Proteins with larger degrees of intrinsic disorder also tend to have short cellular half-life, with disordered segments having been proposed to facilitate efficient initiation of degradation by the proteasome.

After his time at Clark University, Turner had his first career experience at a high school in 1906 when he obtained a position as the principal of College Hill High School in Cleveland, Tennessee. He then resigned the position in order to pursue a professorship in biology and chemistry at Haines Normal and Industrial Institute in Augusta, Georgia in 1907. While he was teaching, he continued to study insect behavior, and also pursued a PhD in zoology at the University of Chicago. He spent the 1906–1907 academic year and the summer of 1906 working on his degree before graduating magna cum laude in 1907. He was the third African American person to receive an advanced degree from the University of Chicago, and possibly the first to receive a doctorate. He was advised by zoologists Charles M. Child, Frank R. Lillie, and Charles O. Whitman.

After the end of the Gemini program, the Soviet Union began flying their second-generation Zond crewed spacecraft in 1967 with the ultimate goal of looping a cosmonaut around the Moon and returning him or her immediately to Earth. The Zond spacecraft was launched with the simpler and already operational Proton launch rocket, unlike the parallel Soviet human Moon landing effort also underway at the time based on third-generation Soyuz spacecraft requiring development of the advanced N-1 booster. The Soviets thus believed they could achieve a crewed Zond circumlunar flight years before a U.S. human lunar landing and so score a propaganda victory. However, significant development problems delayed the Zond program and the success of the U.S. Apollo lunar landing program led to the eventual termination of the Zond effort.

Pisanski’s research interests span several areas of discrete and computational mathematics, including combinatorial configurations, abstract polytopes, maps on surfaces, chemical graph theory, and the history of mathematics and science. In 1980 he calculated the genus of the Cartesian product of any pair of connected, bipartite, "d"-valent graphs using a method that was later called the "White–Pisanski method". In 1982 Vladimir Batagelj and Pisanski proved that the Cartesian product of a tree and a cycle is Hamiltonian if and only if no degree of the tree exceeds the length of the cycle. They also proposed a conjecture concerning "cyclic Hamiltonicity" of graphs. Their conjecture was proved in 2005. With Brigitte Servatius he is the co-author of the book "Configurations from a Graphical Viewpoint" (2013).

Neuroethologists performed several experiments under "Eigenmannia"s natural conditions to study how it determined the sign of the frequency difference. They manipulated the fish's discharge by injecting it with curare which prevented its natural electric organ from discharging. Then, an electrode was placed in its mouth and another was placed at the tip of its tail. Likewise, the neighboring fish's electric field was mimicked using another set of electrodes. This experiment allowed neuroethologists to manipulate different discharge frequencies and observe the fish's behavior. From the results, they were able to conclude that the electric field frequency, rather than an internal frequency measure, was used as a reference. This experiment is significant in that not only does it reveal a crucial neural mechanism underlying the behavior but also demonstrates the value neuroethologists place on studying animals in their natural habitats.

At the time Croatia gained independence, its economy (and the whole Yugoslavian economy) was in the middle of recession. Privatization under the new government had barely begun when war broke out in 1991. As a result of the Croatian War of Independence, infrastructure sustained massive damage in the period 1991–92, especially the revenue-rich tourism industry. Privatization in Croatia and transformation from a planned economy to a market economy was thus slow and unsteady, largely as a result of public mistrust when many state-owned companies were sold to politically well-connected at below-market prices. With the end of the war, Croatia's economy recovered moderately, but corruption, cronyism, and a general lack of transparency stymied economic reforms and foreign investment. The privatization of large government-owned companies was practically halted during the war and in the years immediately following the conclusion of peace. As of 2000, roughly 70% of Croatia's major companies were still state-owned, including water, electricity, oil, transportation, telecommunications, and tourism.

Sleep disturbances such as insomnia, night terrors, and inconsistent REM sleep impact the lives of many with PTSD. Occupational therapists are equipped to address this meaningful area through sleep hygiene. Some examples of this technique are reducing screen time, developing nighttime routines, and creating a safe and quiet environment within the bedroom. Another meaningful area of occupational therapy is self-care. Occupational therapists provide education and adaptation/modification in self-care to maintain independence and prevent triggers that may cause flashbacks. Occupational therapists help clients with PTSD engage in meaningful life roles in daily lives, leisure, and work activities through healthy habit formation and stable daily routines while managing PTSD triggers. Social engagement can be challenging for those with PTSD, and as such, occupational therapists work with their clients to help build a supportive social network of family and friends who can assist in reducing this stress. Occupational therapy interventions also include stress management and relaxation techniques such as deep breathing, mindfulness, meditation, progressive muscle relaxation, and biofeedback. The goal is to help clients adjust to the demands of daily life.

For the first two decades of its existence, UCLA was oriented towards training educators and toward the liberal arts. With the establishment of graduate studies and professional schools, the school gradually became more oriented toward scientific research. The School of Medicine was developed primarily as a research institution, the first of its kind on the West Coast. SWAC, one of the nation's first large computers, powered by vacuum tubes, was built at UCLA in 1950. IBM established the Western Data Processing Center at UCLA in 1956, an early support and regional training center for the use of computers for quantitative research. Other primitive computers obtained by the Center for Health Sciences and Department of Engineering were linked with SWAC to form an early Campus Computing Network.

The single-strand RNA is tightly bound to p7 nucleocapsid proteins, late assembly protein p6, and enzymes essential to the development of the virion, such as reverse transcriptase and integrase. Lysine tRNA is the primer of the magnesium-dependent reverse transcriptase. The nucleocapsid associates with the genomic RNA (one molecule per hexamer) and protects the RNA from digestion by nucleases. Also enclosed within the virion particle are Vif, Vpr, Nef, and viral protease. The envelope of the virion is formed by a plasma membrane of host cell origin, which is supported by a matrix composed of the viral p17 protein, ensuring the integrity of the virion particle. At the surface of the virion can be found a limited number of the envelope glycoprotein (Env) of HIV, a trimer formed by heterodimers of gp120 and gp41. Env is responsible for binding to its primary host receptor, CD4, and its co-receptor (mainly CCR5 or CXCR4), leading to viral entry into its target cell.

The imagination ethic allows a person to step away from the impetuous emotional responses of the older parts of the brain and consider alternative actions based on logic and reason. It is centered in the neocortex and related thalamic structures, including the frontal lobes used for reasoning and judgement skills. It is focused on the outside world and allows for the integration and coordination of the other parts of the brain to allow for imaginative thinking and strategic problem solving. The ethic of imagination involves integrating internal information with external information, allowing an adult to acknowledge and possibly reject more emotional responses from the security or engagement ethics. The imagination ethic can build on the self-protective states of the security ethic (vicious or detached imagination) or of the prosocial engagement ethic (communal imagination).

Many computer installations used cards with the opposite corner cut (sometimes no corner cut) as "job separators", so that an operator could stack several job decks in the card reader at the same time and be able to quickly separate the decks manually when they removed them from the stacker. These cards (e.g., a JCL "JOB" card to start a new job) were often pre-punched in large quantities in advance. This was especially useful when the main computer did not read the cards directly, but instead read their images from magnetic tape that was prepared offline by smaller computers such as the IBM 1401. After reading the cards in, the computer operator would return the card deck – typically to one of a set of alphabetically labelled cubby holes, based on the programmer's last initial. Because programs were run in batch-mode processing it might be a considerable time before any hardcopy printed or punched output was produced, and put into these same cubby holes – however, on a lightly-used system, it was possible to make alterations and rerun a program in less than an hour.

Although the patent office promoted Einstein to Technical Examiner Second Class in 1906, he had not given up on academia. In 1908, he became a "Privatdozent" at the University of Bern. In ""Über die Entwicklung unserer Anschauungen über das Wesen und die Konstitution der Strahlung"" (""), on the quantization of light, and in an earlier 1909 paper, Einstein showed that Max Planck's energy quanta must have well-defined momenta and act in some respects as independent, point-like particles. This paper introduced the "photon" concept (although the name "photon" was introduced later by Gilbert N. Lewis in 1926) and inspired the notion of wave–particle duality in quantum mechanics. Einstein saw this wave–particle duality in radiation as concrete evidence for his conviction that physics needed a new, unified foundation.

The person is usually placed on their side (left more commonly than right). The patient bends the neck so the chin is close to the chest, hunches the back, and brings knees toward the chest. This approximates a fetal position as much as possible. Patients may also sit on a stool and bend their head and shoulders forward. The area around the lower back is prepared using aseptic technique. Once the appropriate location is palpated, local anaesthetic is infiltrated under the skin and then injected along the intended path of the spinal needle. A spinal needle is inserted between the lumbar vertebrae L3/L4, L4/L5 or L5/S1 and pushed in until there is a "give" as it enters the lumbar cistern wherein the ligamentum flavum is housed. The needle is again pushed until there is a second 'give' that indicates the needle is now past the dura mater. The arachnoid membrane and the dura mater exist in flush contact with one another in the living person's spine due to fluid pressure from CSF in the subarachnoid space pushing the arachnoid membrane out towards the dura. Therefore, once the needle has pierced the dura mater it has also traversed the thinner arachnoid membrane. The needle is then in the subarachnoid space. The stylet from the spinal needle is then withdrawn and drops of cerebrospinal fluid are collected. The opening pressure of the cerebrospinal fluid may be taken during this collection by using a simple column manometer. The procedure is ended by withdrawing the needle while placing pressure on the puncture site. The spinal level is so selected to avoid spinal injuries. In the past, the patient would lie on their back for at least six hours and be monitored for signs of neurological problems. There is no scientific evidence that this provides any benefit. The technique described is almost identical to that used in spinal anesthesia, except that spinal anesthesia is more often done with the patient in a seated position.

Social-ecological resilience, also known as adaptive resilience, is a new concept that shifts the focus to combining the social, ecological and technical domains of resilience. The adaptive model focuses on the transformable quality of the stable state of a system. In adaptive buildings, both short term and long term resilience are addressed to ensure that the system can withstand disturbances with social and physical capacities. Buildings operate at multiple scale and conditions, therefore it is important to recognize that constant changes in architecture are expected. Laboy and Fannon recognize that the resilience model is shifting, and have applied the MCEER four properties of resilience to the planning, designing and operating phases of architecture. Rather than using four properties to describe resilience, Laboy and Fannon suggest a 6R model that adds Recovery for the operation phase of a building and Risk Avoidance for the planning phase of the building. In the planning phase of a building, site selection, building placement and site conditions are crucial for the risk avoidance. Early planning can help prepare and design for the built environment based on forces that we understand and perceive. In the operation phase of the building, a disturbance does not mark the end of resilience, but should propose a recovery plan for future adaptations. Disturbances should be used as a learning opportunity to assess mistakes and outcomes, and reconfigure for future needs.

Magendie was also a notorious vivisector, shocking even many of his contemporaries with the live dissections that he performed at public lectures in physiology. Richard Martin, an Irish MP, in introducing his famous bill banning animal cruelty in the United Kingdom, described Magendie's public dissection of a greyhound, in which the beast was nailed down ear and paw, half the nerves of its face dissected then left overnight for further dissection, calling Magendie a "disgrace to Society." There was a belief among British physicians, even those who defended animal experimentation, that Magendie purposely subjected his experimental animals to needless torture. A Quaker once visited him, questioning him about vivisection; according to Anne Fagot-Largeau's inaugural lesson at the College of France, he responded with much patience, argumenting the reasons of animal experimentation. Besides drawing sharp criticism from contemporaries in both Britain and France, Magendie's methods were later criticized by, among others, Charles Darwin and Thomas Henry Huxley.

Richard Osborne reviewed the album on LP in "Gramophone" in June 1978, comparing it with alternative versions of the "symphony of heavenly life" conducted by Otto Klemperer, Rafael Kubelik, James Levine and George Szell. Claudio Abbado's reading of the first movement, he wrote, was straightforward, colourful and likeable. Like Szell, Abbado opened with a tempo that was animated without being flustered, and he was meticulous in his obedience to Mahler's accents and dynamics. After a few minutes, though, the "apparently episodic" character of the movement caused him to lose sight of the wood for the trees. Where Szell had acknowledged the movement's "unity in diversity" with a "steady, treading pulse" that "[refused] to ignore the thrust of the downbeat", Abbado paced the score erratically. Figure 7 exemplified Abbado's "losing his way" at a point where Szell had managed to allow himself a liberal rubato without disrupting the music's fundamental rhythm.

Widespread inappropriate use of the procedure later led to it falling out of use. However, it was reintroduced by Hermann Schwartze in the 19th century. An inherent problem became recognized, namely the tendency of the tympanic membrane to heal spontaneously and rapidly, reversing the beneficial effects of the perforation. In order to prevent this, a tympanostomy tube, initially made of gold foil, was placed through the incision to prevent it from closing. In 1819 the French physician Antoine Saissy (1756-1822) tried to keep the myringotomy unsuccessfully open with Catgut. Ádám Politzer, a Hungarian-born otologist practicing in Vienna, experimented with rubber in 1886. The German otologist Rudolf Voltolini (1819-1889) created in 1874 a grommet made of gold and later on one made of aluminium. The vinyl tube used today was introduced by Beverly Armstrong in 1954.

The final style of Chinchorro mummification was the mud-coat (3000-1300 BCE). Ecologically speaking, at the time of the Chinchorro culture the region was relatively stable. It has been suggested by environmentalists that the incredible preservation of these mummies is also influenced by the pedogenic (the evolution of soil) creation of clays and gypsum, which act as cementing agents, and the latter as a natural desiccant. The malleable clay allowed for the morticians to mold and create the colorful appearances of mummies, with the added bonus of the fact that the foul smell of the desiccating mummy would be covered. Artisans no longer removed the organs of the dead; instead a thick coat of mud, sand and a binder like egg or fish glue was used to cover the bodies. Once completed the mummies were cemented into their graves. The change in style may have come from exposure to outsiders and their different cultures, or from the association of disease with the rotting corpses.

If light is then applied to the capacitor it will change capacitance to a new value: formula_8. The charge that the plates can accommodate will therefore change to formula_9, leaving a surplus / deficit of charge on each plate. The excess charge will be forced to leave the plates, flowing either to ground or the input voltage terminal. The rate of charge flow is determined by the resistance of the resistor formula_10, and the capacitance of the capacitor. This charge flow will lead to a non-zero voltage being dropped across the resistor and hence a non-zero formula_1. After the charge stops flowing the system returns to steady-state, all the voltage is once again dropped across the capacitor, and formula_3 again.For a capacitor to change its capacitance under illumination, the dielectric constant of the insulator between the plates, or the effective dimensions of the capacitor, must be illumination-dependent. The effective dimensions can be changed by using a bilayer material between the plates, consisting of an insulator and a semiconductor. Under appropriate illumination conditions the semiconductor will increase its conductivity when exposed to light, emulating the process of moving the plates of the capacitor closer together, and therefore increasing capacitance. For this to be possible, the semiconductor must have a low electrical conductivity in the dark, and have an appropriate band gap to enable charge generation under illumination. The device must also allow optical access to the semiconductor, through a transparent plate (e.g. using a transparent conducting oxide).

Individual organisms participating in a biological life cycle ordinarily age and die, while cells from these organisms that connect successive life cycle generations (germ line cells and their descendants) are potentially immortal. The basis for this difference is a fundamental problem in biology. The Russian biologist and historian Zhores A. Medvedev considered that the accuracy of genome replicative and other synthetic systems alone cannot explain the immortality of germ lines. Rather Medvedev thought that known features of the biochemistry and genetics of sexual reproduction indicate the presence of unique information maintenance and restoration processes at the gametogenesis stage of the biological life cycle. In particular, Medvedev considered that the most important opportunities for information maintenance of germ cells are created by recombination during meiosis and DNA repair; he saw these as processes within the germ line cells that were capable of restoring the integrity of DNA and chromosomes from the types of damage that cause irreversible ageing in non-germ line cells, e.g. somatic cells.

Barnes Wallis, deputy chief aircraft designer at Vickers, spent much time thinking about weapons that might shorten the war. He conceived his “Spherical Bomb, Surface Torpedo” after watching his daughter flip pebbles over water. Two versions of the 'bouncing bomb' were developed: the smaller Highball was to be used against ships and attracted essential British Admiralty funding for his project. A flying torpedo, of which half was Torpex torpedo explosive, it was developed specifically to sink the Tirpitz which was moored in Trondheim fjord behind torpedo nets. Development delays in the 'bouncing bomb' meant that another Barnes Wallis invention, the 5-ton Tallboy was deployed instead; two Tallboys dropped by Avro Lancasters from altitude hit at near-supersonic speed and capsized the Tirpitz on November 12, 1944. Upkeep, the larger version of the bouncing bomb, was used to destroy the Mohne and Eder dams by Lancasters from the specially recruited and trained No. 617 Squadron RAF, often known as "the Dam Busters", under Wing Commander Guy Gibson.

Because of the range of Japanese Kaidai-type submarines – sometimes more than 10,000 miles (16,000 km) -- Japanese forward bases on Madagascar could have threatened Allied merchant shipping and the supply route of the British Eighth Army and the Eastern Fleet, and affected Allied lines of communication from Australia and the Pacific to the Middle East and as far away as the South Atlantic.

The facility was founded by the United States Army during World War I arising from the need to treat the large number of casualties from chemical weapons in Europe. Denver's reputation as a prime location for the treatment of tuberculosis led local citizens to lobby the Army on behalf of Denver as the site for the new hospital. Army Hospital 21, as it was first called, was formally dedicated in the autumn of 1918 in Aurora, which at the time had a population of less than 1,000. In July 1920, the facility was formally renamed the Fitzsimons Army Hospital after Lt. William T. Fitzsimons, the first American medical officer killed in World War I. A new main building, known as Building 500, was built in 1941. At the time, it was the largest structure in Colorado.

The last generation of Pentium D branded processors was Presler released on January 16, 2006, identified by the product code 80553, and made of two 65 nm-process cores found also in Pentium 4 branded Cedar Mill CPUs. "Presler" introduced the 'multi-chip module, or MCM, which consisted of two single-core dies placed next to each other on the same substrate package. This allowed Intel to produce these processors at a reduced production cost as a result of higher yields. "Presler" was supported by the same chipsets as "Smithfield". It was produced using 65 nm technology similar to Yonah. "Presler" communicated with the system using an 800 MT/s FSB, and its two cores communicated also using the FSB, just as in "Smithfield". "Presler" also included Intel VT-x (formerly Vanderpool) – although this was limited to the 9x0 models, and not in the 9x5 models– Intel 64, XD bit, and EIST (Enhanced Intel SpeedStep Technology). "Presler" was released in the first quarter of 2006 with a 2x2 MB Level 2 cache. Its models included 915, 920, 925, 930, 935, 940, 945, 950 and 960 (with a respective 2.8, 2.8, 3.0, 3,0, 3.2, 3.2, 3.4, 3.4, and 3.6 GHz clock frequency).

NASA scientists studying pictures from the "Odyssey" spacecraft have spotted what might be seven caves on the flanks of the Arsia Mons volcano on Mars. The pit entrances measure from wide and they are thought to be at least deep. See image below: the pits have been informally named (A) Dena, (B) Chloe, (C) Wendy, (D) Annie, (E) Abby (left) and Nikki, and (F) Jeanne. Dena's floor was observed and found to be 130 m deep. Further investigation suggested that these were not necessarily lava tube "skylights". Review of the images has resulted in yet more discoveries of deep pits. Recently, a global database (MG) of over 1,000 Martian cave candidates at Tharsis Montes has been developed by the USGS Astrogeology Science Center. In 2021, scientists are applying machine-learning algorithms to extend the MG database across the entire surface of Mars.
