The forest also decreased gradually northwards in Europe, but in the Nordic countries it has survived. The clans in pre-Roman Italy seemed to be living in temporary locations rather than established cities. They cultivated small patches of land, guarded their sheep and their cattle, traded with foreign merchants, and at times fought with one another: etruscans, umbriere, ligurianere, sabinere, Latinos, campaniere, apulianere, faliscanere, and samniter, just to mention a few. These Italic ethnic groups developed identities as settlers and warriors c. 900 BC. They built forts in the mountains, today a subject of much investigation. The forest has hidden them for a long time, but eventually, they will provide information about the people who built and used these buildings. The ruin of a large samnittisk temple and theater at Pietrabbondante is under investigation. These cultural relics have slumbered in the shadow of the glorious history of the Roman Empire.

The Flyers had many bright spots on their roster in 1955-56, with the brightest light the play of their sensational young rookie, Art "the dart" Jones. He not only won the rookie award by a wide margin, but also paced the league in the goal department with 44 goals, five more than his teammate Lorne Nadeau. Jack Lancien, Spokane's star defenceman, was unanimously chosen the winner of the Paul Kozak Memorial Trophy, as the league's best rearguard. Lancien, a 33-year-old former pro, was a tower of strength on the Flyers blueline, and proved one point, that a defenceman doesn't have to be crude to win the respect of fans and players. He was a real leader, picking up only 13 minutes in penalties, and gathered 39 points, made up of seven goals and 32 assists.

Security analysis is the analysis of tradeable financial instruments called securities. It deals with finding the proper value of individual securities (i.e., stocks and bonds). These are usually classified into debt securities, equities, or some hybrid of the two. Tradeable credit derivatives are also securities. Commodities or futures contracts are not securities. They are distinguished from securities by the fact that their performance is not dependent on the management or activities of an outside or third party. Options on these contracts are however considered securities, since performance is now dependent on the activities of a third party. The definition of what is and what is not a security comes directly from the language of a United States Supreme Court decision in the case of SEC v. W. J. Howey Co. Security analysis for the purpose to state the effective value of an enterprise is typically based on the examination of fundamental business factors such as financial statements, going concern, business strategy and forecasts.

A point O (fig. 2) at a finite distance from the axis (or with an infinitely distant object, a point which subtends a finite angle at the system) is, in general, even then not sharply reproduced if the pencil of rays issuing from it and traversing the system is made infinitely narrow by reducing the aperture stop; such a pencil consists of the rays which can pass from the object point through the now infinitely small entrance pupil. It is seen (ignoring exceptional cases) that the pencil does not meet the refracting or reflecting surface at right angles; therefore it is astigmatic (Gr. a-, privative, stigmia, a point). Naming the central ray passing through the entrance pupil the "axis of the pencil" or "principal ray," it can be said: the rays of the pencil intersect, not in one point, but in two focal lines, which can be assumed to be at right angles to the principal ray; of these, one lies in the plane containing the principal ray and the axis of the system, i.e. in the "first principal section" or "meridional section", and the other at right angles to it, i.e. in the second principal section or sagittal section. We receive, therefore, in no single intercepting plane behind the system, as, for example, a focusing screen, an image of the object point; on the other hand, in each of two planes lines O' and O" are separately formed (in neighboring planes ellipses are formed), and in a plane between O' and O" a circle of least confusion. The interval O'O", termed the astigmatic difference, increases, in general, with the angle W made by the principal ray OP with the axis of the system, i.e. with the field of view. Two "astigmatic image surfaces" correspond to one object plane; and these are in contact at the axis point; on the one lie the focal lines of the first kind, on the other those of the second. Systems in which the two astigmatic surfaces coincide are termed anastigmatic or stigmatic.

In addition to gender (male predominance) and race (mainly a disease of Caucasian individuals), established risk factors for EoE include atopy and other allergic conditions. Other recognized genetic and environmental risk factors for EoE include alterations in gut barrier function (e.g. GERD), variation in the nature and timing of oral antigen exposure, lack of early exposure to microbes, and an altered microbiome. A study comparing active EoE children to non EoE children found an altered microbiome due to a positive correlation between a relatively high abundance of Haemophilus and disease activity seen through an increasing Eosinophilic Esophagitis Endoscopic Reference Score and Eosinophilic Esophagitis Histologic Scoring System (q value = 5e-10). Measuring the relative abundance of specific taxa in children’s salivary microbiome could serve as a noninvasive marker for eosinophilic esophagitis.

There is a strong tradition of student media at St Andrews. The university's two newspapers are "The Saint", a fortnightly publication and "The Stand", an online publication founded in 2011. There is also the "Foreign Affairs Review" ran by the Foreign Affairs Society and the first legal publication in town – the "St Andrews Law Review -" was launched in 2020. There are also a number of smaller student publications including "The Wynd", a student-run magazine and "The Regulus", a student magazine focusing on politics and current affairs. In addition to this there are several student-led academic journals, most notably, "Stereoscope Magazine" which is focused on student photography and raising awareness of the university's historic photographic collection, "Ha@sta", an annual journal for those interested in art history, "Aporia", the journal of the Philosophy Society, and the "Postgraduate Journal of Art History and Museum Studies". The university's radio station is "STAR: St Andrews Radio", an online station that broadcasts 24/7 during term time. "Scoot Around" is a literary-cultural magazine based in St Andrews with contributors from universities around the world."The Sinner" is an independent website and discussion forum set up by students of the university.

The closest objects in extragalactic astronomy include the galaxies of the Local Group, which are close enough to allow very detailed analyses of their contents (e.g. supernova remnants, stellar associations). As instrumentation has improved, distant objects can now be examined in more detail and so extragalactic astronomy includes objects at nearly the edge of the observable universe. Research into distant galaxies (outside of our local group) is valuable for studying aspects of the universe such as galaxy evolution and Active Galactic Nuclei (AGN) which give insight into physical phenomena (e.g. super massive black hole accretion and the presence of dark matter). It is through extragalactic astronomy that astronomers and physicists are able to study the effects of General Relativity such as gravitational lensing and gravitational waves, that are otherwise impossible (or nearly impossible) to study on a galactic scale.

Publicly available information from biomedical documents is readily accessible through the internet and is becoming a powerful resource for collecting known protein-protein interactions (PPIs), PPI prediction and protein docking. Text mining is much less costly and time-consuming compared to other high-throughput techniques. Currently, text mining methods generally detect binary relations between interacting proteins from individual sentences using rule/pattern-based information extraction and machine learning approaches. A wide variety of text mining applications for PPI extraction and/or prediction are available for public use, as well as repositories which often store manually validated and/or computationally predicted PPIs. Text mining can be implemented in two stages: "information retrieval", where texts containing names of either or both interacting proteins are retrieved and "information extraction," where targeted information (interacting proteins, implicated residues, interaction types, etc.) is extracted.

3x3 basketball (pronounced "three-ex-three") is a variation of basketball played three-a-side, with one backboard and in a half-court setup. According to an ESSEC Business School study commissioned by the International Olympic Committee, 3x3 is the largest urban team sport in the world. This basketball game format is currently being promoted and structured by FIBA, the sport's governing body. Its primary competition is an annual FIBA 3X3 World Tour, comprising a series of Masters and one Final tournament, and awarding six-figure prize money in US dollars. The FIBA 3x3 World Cups for men and women are the highest tournaments for national 3x3 teams. The 3x3 format has been adopted for both the 2020 Summer Olympics and 2022 Commonwealth Games.

The linear search problem was solved by Anatole Beck and Donald J. Newman (1970) as a two-person zero-sum game. Their minimax trajectory is to double the distance on each step and the optimal strategy is a mixture of trajectories that increase the distance by some fixed constant. This solution gives search strategies that are not sensitive to assumptions concerning the distribution of the target. Thus, it also presents an upper bound for a worst-case scenario. This solution was obtained in the framework of an online algorithm by Shmuel Gal, who also generalized this result to a set of concurrent rays. The best online competitive ratio for the search on the line is 9 but it can be reduced to 4.6 by using a randomized strategy. Demaine et al. gave an online solution with a turn cost.

In 2017 Orbital ATK filed suit via the U.S. District court in the district of Minnesota against Heckler and Koch for damages of over US$27 million, claiming failure to deliver 20 XM25 prototype units. The filing also requested Transfer of Intellectual Property to allow Orbital ATK to contract another vendor for production of the system. The complaint stated that Heckler and Koch had wished legal clarification regarding potential violations of the Saint Petersburg Declaration of 1868, which bans "any projectile of a weight below 400 grams" containing explosives. After consultation Heckler and Koch had stipulated that the US Government issue a special certification regarding use of the weapons system. The US Government did not issue such and negotiations broke down. In April 2017, the Army cancelled its contract with Orbital ATK after they failed to deliver 20 weapons as specified by the terms, putting the operational future of the XM25 in jeopardy.

Key points in the Colorado Plan include reducing emission levels and solutions by sector. Agriculture, transportation, green electricity, and renewable energy research are the main concepts and goals in this plan. Political programs such as mandatory vehicle emissions testing and the prohibition of smoking indoors are actions taken by local government to create public awareness and participation in cleaner air. The location of Denver next to the Rocky Mountains and wide expanse of plains makes the metro area of Colorado's capital city a likely place for smog and visible air pollution.

The post-antibiotic effect (PAE) is defined as persistent suppression of bacterial growth after a brief exposure (1 or 2 hours) of bacteria to an antibiotic even in the absence of host defense mechanisms. Factors that affect the duration of the post-antibiotic effect include duration of antibiotic exposure, bacterial species, culture medium and class of antibiotic. It has been suggested that an alteration of DNA function is possibly responsible for the post-antibiotic effect following the observation that most inhibitors of protein and nucleic acid synthesis (aminoglycosides, fluoroquinolones, tetracyclines, clindamycin, certain newer macrolides/ketolides, and rifampicin and rifabutin) induce long-term PAE against susceptible bacteria. Theoretically, the ability of an antibiotic to induce a PAE is an attractive property since antibiotic concentrations could fall below the MIC for the bacterium yet retain their effectiveness in their ability to suppress the growth. Therefore, an antibiotic with PAE would require less frequent administration and it could improve patient adherence with regard to pharmacotherapy. Proposed mechanisms include (1) slow recovery after reversible nonlethal damage to cell structures; (2) persistence of the drug at a binding site or within the periplasmic space; and (3) the need to synthesize new enzymes before growth can resume. Most antimicrobials possess significant in vitro PAEs (≥ 1.5 hours) against susceptible gram-positive cocci. Antimicrobials with significant PAEs against susceptible gram-negative bacilli are limited to carbapenems and agents that inhibit protein or DNA synthesis.

George Laurer was born on September 23, 1925, in New York City. His family moved to Baltimore, Maryland, so his father, an electrical engineer, could work for the United States Navy. Laurer recovered from polio which he contracted as a teenager, nonetheless, while in 11th grade, he was drafted into the U.S. Army during World War II. After being discharged from the military, he attended technical school where he studied radio and television repair. Upon completion of his first year at the technical school, his instructor convinced him that he should not continue that course of study, but that he should go to college. Laurer graduated from the A. James Clark School of Engineering at the University of Maryland in 1951. He was still interested in radio and kept up his amateur radio licence.

The egg parasite "Trichogramma" is frequently released inundatively to control harmful moths. New way for inundative releases are now introduced i.e. use of drones. Egg parasitoids are able to find the eggs of the target host by means of several cues. Kairomones were found on moth scales. Similarly, "Bacillus thuringiensis" and other microbial insecticides are used in large enough quantities for a rapid effect. Recommended release rates for "Trichogramma" in vegetable or field crops range from 5,000 to 200,000 per acre (1 to 50 per square metre) per week according to the level of pest infestation. Similarly, nematodes that kill insects (that are entomopathogenic) are released at rates of millions and even billions per acre for control of certain soil-dwelling insect pests.

Affinity tags have been widely used to purify recombinant proteins, as they allow the accumulation of recombinant protein with little impurities. However, the affinity tag must be removed by proteases in the final purification step. The extra proteolysis step raises the problems of protease specificity in removing affinity tags from recombinant protein, and the removal of the digestion product. This problem can be avoided by fusing an affinity tag to self-cleavable inteins in a controlled environment. The first generation of expression vectors of this kind used modified "Saccharomyces cerevisiae" VMA (Sce VMA) intein. Chong et al. used a chitin binding domain (CBD) from "Bacillus circulans" as an affinity tag, and fused this tag with a modified Sce VMA intein. The modified intein undergoes a self-cleavage reaction at its N-terminal peptide linkage with 1,4-dithiothreitol (DTT), β-mercaptoethanol (β-ME), or cystine at low temperatures over a broad pH range. After expressing the recombinant protein, the cell homogenate is passed through the column containing chitin. This allows the CBD of the chimeric protein to bind to the column. Furthermore, when the temperature is lowered and the molecules described above pass through the column, the chimeric protein undergoes self-splicing and only the target protein is eluted. This novel technique eliminates the need for a proteolysis step, and modified Sce VMA stays in column attached to chitin through CBD.

Differential signalling is often used in computers to reduce electromagnetic interference, because complete screening is not possible with microstrips and chips in computers, due to geometric constraints and the fact that screening does not work at DC. If a DC power supply line and a low-voltage signal line share the same ground, the power current returning through the ground can induce a significant voltage in it. A low-resistance ground reduces this problem to some extent. A balanced pair of microstrip lines is a convenient solution because it does not need an additional PCB layer, as a stripline does. Because each line causes a matching image current in the ground plane, which is required anyway for supplying power, the pair looks like four lines and therefore has a shorter crosstalk distance than a simple isolated pair. In fact, it behaves as well as a twisted pair. Low crosstalk is important when many lines are packed into a small space, as on a typical PCB.

The origins of the Institute date back to 1973 when the Royal Family of Travancore gifted a multi-storey building, for the people of the region, and the Government of Kerala resolved to develop the gift as the Sree Chitra Tirunal Medical Centre for medical specialties. Sri P N Haksar, the then Deputy Chairman of the Planning Commission, inaugurated the Sree Chitra Tirunal Medical Centre in 1976, and patient services got under way. The Biomedical Technology Wing followed soon at the Satelmond Palace, an exquisite gift of the Royal family, located 11 km away from the Hospital Wing. The Vision of the first Director, Professor M S Valiathan, transformed the Centre into a unique institution that blends the practice of Department of Cardiology modern medicine with relevant research and technology within the same institutional framework.

As of 2018, the exact mechanism of action of artemisinins has not been fully elucidated. Artemisinin itself is a prodrug of the biologically active dihydroartemisinin. This metabolite undergoes cleavage of its endoperoxide ring inside the erythrocytes. As the drug molecules come in contact with the haem (associated with the hemoglobin of the red blood cells), the iron(II) oxide breaks the endoperoxide ring. This process produces free radicals that in turn damage susceptible proteins, resulting in the death of the parasite. In 2016 artemisinin was shown to bind to a large number of targets suggesting that it acts in a promiscuous manner. Artemisinin's endoperoxide moiety is however less sensitive to free iron(II) oxide, and therefore more active in the intraerythrocytic stages of "P. falciparum". In contrast, clinical practice shows that unlike other antimalarials, artemisinin is active during all life cycle stages of the parasite.

Once Typhoons started operating from forward landing grounds in Normandy, it was found that the dust clouds stirred up by propeller wash consisted of over 80 percent of hard, abrasive material which was damaging the Sabre engines. The sleeve valves in particular were subject to excessive wear and it was calculated that engines would last for three take-offs. As a result, a "dome deflector" was designed and manufactured at great speed by Napier, and within a week most Typhoons had been fitted with it. In operational service these mushroom-shaped air filters, which became red hot, had a propensity for being blown off the air intake at high speed whenever a Sabre engine backfired. They were soon replaced by drum-shaped filters designed by the RAE and Vokes. These had "cuckoo clock" doors in front, which swung open with the pressure changes caused by engine backfires. This standardised filter became Typhoon Mod.420.

In the early 20th century, forecasting the track of cyclones was still confined to areas of the greatest surface pressure falls, based upon surface weather observations, and climatology. These methods proved to be the cutting edge of tropical cyclone forecasting through the mid 20th century. Land-based surface observations remain invaluable as a source of real-time information at locations near the coastline and inland. Combined with ship observations and newspapers, they formed the total information network for hurricane detection until radiosondes were introduced in 1941 and reconnaissance aircraft began in 1944. Land-based observations of pressure and wind can show how quickly a tropical cyclone is decaying as it moves inland. Their rainfall reports show where significant rainfall is occurring, and can be an alert for possible flooding. With the establishment of the ASOS network in the United States during the 1990s, more locations are reporting around the clock than ever before.

Genetic screens can be carried out to determine potential genes followed by other tests that identify the best candidates. A simple screen involves randomly mutating DNA with chemicals or radiation and then selecting those that display the desired trait. For organisms where mutation is not practical, scientists instead look for individuals among the population who present the characteristic through naturally-occurring mutations. Processes that look at a phenotype and then try and identify the gene responsible are called forward genetics. The gene then needs to be mapped by comparing the inheritance of the phenotype with known genetic markers. Genes that are close together are likely to be inherited together.

Theiss designed a shield-shaped badge in 1964 which he called the "arrowhead", with input from Roddenberry. This came to be known as the "Star Trek delta insignia", and has since become iconic of the Starship "Enterprise" and the entire Star Trek franchise. Roddenberry's intent was that personnel of all starfleet starships would wear this, but in production of the first season episode "The Omega Glory”, Theiss mistakenly got the idea that each starship would have a unique insignia, from the fact that some starship officers in an earlier episode "Charlie X" wore a different insignia (see "Civilian starship duty"). He therefore designed a rectangular insignia worn by the captain and the chief medical officer of the USS "Exeter". Shortly before October 7, 2018, a December 18 1967 memo to Theiss from producer Bob Justman was discovered. Justman noticed the error while reviewing footage and consulted with Roddenberry, who clarified that this indeed was a mistake: all Starfleet starship personnel are to wear the delta insignia as seen on the Enterprise crew uniform. Footage was not reshot to correct the error, but Justman made it clear it was not to be repeated. Going forward, the delta symbol remained consistent for all starship personnel, as seen in “” and “The Tholian Web”.

"Dependoparvovirus" is not infectious enough to trigger an immune response; this makes it a good virus to use as a gene therapy tool. Gene therapy is a possible treatment for a variety of disorders and diseases that are genetic in origin. Viral vectors are currently being developed to transport genes into human cells. Since this virus does not stimulate an immune response it can be used multiple times effectively without being neutralized before infection . Another reason these viruses are reliable vectors is the known insertion point for the genome. This virus always inserts its contents into the same place on chromosome 19. This predictability can cut down on the chances of inserting into an important area that might disrupt normal gene function or increase the risk of developing cancer.

In 1971, he wrote a short and provocative note for Page, the Bulletin of the Computer Arts Society (whose member he was and still is), under the title „There Should Be No Computer-Art“ (Page No. 18, Oct. 1971, p. 1-2. Reprinted in Arie Altena, Lucas van der Velden (eds.): The anthology of computer art. Amsterdam: Sonic Acts 2006, p. 59-60). The note sparked a lively controversial debate among those who had meanwhile started to build an active community of artists, writers, musicians, and designers in the digital domain. His statement was rooted in a moral position. The involvement of computer technology in the Vietnam War and in massive attempts by capital to automate productive processes and, thereby, generate unemployment, should not allow artists to close their eyes and become silent servants of the ruling classes by reconciling high technology with the masses of the poor and suppressed.

Modifications of this early work have been implemented to perform AFM analysis on both conducting and non-conducting materials. Conductive atomic force microscopy (c-AFM) is one such modification technique. The c-AFM technique operates by measuring fluctuations in current from the biased tip and sample while simultaneously measuring changes in the topographical features. In all techniques of AFM, two modes of operation can be used: contact mode and non-contact mode. In c-AFM resonant contact mode is used to obtain topographical from current that is measured between the biased AFM tip and the sample surface. In this type of operation, the current is measured in the small space between the tip and the sample surface. This quantification is based on the relationship between the current traveling through the sample and layer thickness. In the previous equation, A is the effective emission area at the injecting electrode, q is the electron charge, h is planck's constant, "m" / "m" =0.5, which is the effective mass of an electron in the conduction band of a sample, "d" is the sample thickness and "Φ" is the barrier height. The symbol, "β", the field enhancement factor, accounts for the non-planar, geometry of the tip used.

In 1944, the US Army contracted for an electronic "computer with guns, a tracking radar, plotting boards and communications equipment" (M33C & M33D models used different subassemblies for 90 & 120 mm gun/ammunition ballistics.) The "trial model predecessor" (T-33) was used as late as 1953, and the production M33 (each $383,000 in 1954 dollars) had been deployed in 1950. The 34th AAA Brigade's 90mm guns were converted to the M-33 by December 3, 1954, after the 95th AAA Brigade had been upgraded. Aberdeen Proving Ground and Fort Bliss were training posts for M-33 personnel, and by 1957 there were 3 Ordnance Detachments in Germany for M33 Integrated Fire Control Repair—150th (Wiesbaden), 151st (Mannheim), & 152nd (Kaiserslautern) Ord Det (IFCR); and functional test sites included the White Sands Proving Ground ranges (e.g., "Hueco Range No. 3). The M33 was also used for satellite tracking in 1961.

San Francisco area artist Julie Newdoll, who holds a degree in Microbiology with a minor in art, has specialized in paintings inspired by microscopic images and molecules since 1990. Her painting "Rise of the Alpha Helix" (2003) features human figures arranged in an α helical arrangement. According to the artist, "the flowers reflect the various types of sidechains that each amino acid holds out to the world". This same metaphor is also echoed from the scientist's side: "β sheets do not show a stiff repetitious regularity but flow in graceful, twisting curves, and even the α-helix is regular more in the manner of a flower stem, whose branching nodes show the influence of environment, developmental history, and the evolution of each part to match its own idiosyncratic function."

These issues can be somewhat mitigated by using smaller districts, because they show finer variations in the mapped variable, and their smaller visual size and increased number reduces the likelihood that the map user makes judgments about the variation within a single district. However, they can make the map overly complex, especially if there is not a meaningful geographic pattern in the variable (i.e., the map looks like randomly scattered colors). Although representing specific data in large regions can be misleading, the familiar district shapes can make the map clearer and easier to interpret and remember. The choice of regions will ultimately depend on the map's intended audience and purpose. Alternatively, the dasymetric technique can sometimes be employed to refine the region boundaries to more closely match actual changes in the subject phenomenon.

RNC is the home of the first football academy for visually impaired players. The Football Academy was officially opened in August 2008 by former England footballer Sir Trevor Brooking and offers visually impaired students the opportunity to include football as part of their study programme with a view to playing the game at a national level. The college is the home of the England blind football team, which is supported by the Football Association and coached by former professional footballer Tony Larkin. The game is played as a five-a-side match using a ball filled with ballbearings to enable players to hear its position. Teams consist of four blind players and a sighted goalkeeper who offers directions along with the coach and a sighted guide behind the opposition goalpost. RNC is helping to develop a national blind football league. In 2010 RNC hosted the World Blind Football Championship at its campus. The tournament got under way on Saturday 14 August with the opening match between England and Spain, and was won by Brazil following a 2–0 win against Spain in the final on 22 August. Members of England's blind football team travelled to Los Angeles in November 2011 to promote the sport in the United States, and took part in a day's training with former England captain David Beckham. The trip was organised by supermarket chain Sainsbury's as part of their sponsorship deal with the footballer.

Most patients with severe TBI who recover consciousness experience cognitive disabilities, including the loss of many higher-level mental skills. Cognitive deficits that can follow TBI include impaired attention; disrupted insight, judgement, and thought; reduced processing speed; distractibility; and deficits in executive functions such as abstract reasoning, planning, problem-solving, and multitasking. Memory loss, the most common cognitive impairment among head-injured people, occurs in 20–79% of people with closed head trauma, depending on severity. Post-traumatic amnesia (PTA), a confusional state with impaired memory, is characterized by loss of specific memories or the partial inability to form or store new ones.

In 1950, The Catholic Archdiocese of Louisville founded Bellarmine College with a pioneer class of 115 freshmen. The only building, Pasteur Hall, was still without its front door on the first day of classes. Archbishop John A. Floersh called the school into existence at its first Convocation, saying, "We are looking forward to the day when the college ranks with the great colleges of our country." From its opening day under founding President Horrigan, Bellarmine welcomed people of all faiths and races. In 1953 the college added the Administration Building (now Horrigan Hall). At its first commencement in 1954, Bellarmine graduated 42 students. The Korean War interrupted or ended the educations of many in the pioneer class, but the school persevered despite rumors of closure. In December 1956, the Southern Association of Colleges and Schools formally announced Bellarmine's accreditation. Enrollment rose from the initial 115 in 1950 to 1,033 in 1959.

The release of unique VOCs and extrafloral nectar (EFN) allow plants to protect themselves against herbivores by attracting animals from the third trophic level. For example, caterpillar-damaged plants guide a parasitic wasp to prey on its victims through the release of chemical signals.The sources of these compounds are most likely from glands in the leaves which are ruptured upon the chewing of an herbivore. The injury by herbivores induces the release of linolenic acid and other enzymatic reactions in an octadecanoid cascade, leading to the synthesis of jasmonic acid, a hormone which plays a central role in regulating immune responses. Jasmonic acid induces the release of VOCs and EFN which attract parasitic wasps and predatory mites to detect and feed on herbivores. These volatile organic compounds can also be released to other nearby plants to be prepared for the potential threats. Studies have shown that the volatile compounds emitted by plants are easy to be detected by third trophic level organisms as these signals are unique to herbivore damage. An experiment conducted to measure the VOCs from growing plants shows that signals are released instantaneously upon the herbivory damage and slowly dropped after the damage stopped. It was also observed that plants release the strongest signals during the time of day which animals tend to forage.

Most of the examples for tactical applications of notation could appear in the other sections of direct applications of notational analysis, but their initial aims were linked with analysis of tactics. The interesting theme that is emerging, from some of the recent research, is that the tactical models that are defined are changing with time, as players become fitter, stronger, faster, bigger (think of the changes in rugby union since professionalisation in 1996), and the equipment changes – for example, the rackets in all the sports have become lighter and more powerful. Over a period of less than 15 years the length of rallies in squash, for elite players, has decreased from about 20 shots, to about 12 shots per rally. An excellent review (Croucher, 1996) of the application of strategies using notational analysis of different sports outlines the problems, advantages and disadvantages associated with this function.

Unlike many other brain disorders, such as Parkinson's, autism does not have a clear unifying mechanism at either the molecular, cellular, or systems level; it is not known whether autism is a few disorders caused by mutations converging on a few common molecular pathways, or is (like intellectual disability) a large set of disorders with diverse mechanisms. Autism appears to result from developmental factors that affect many or all functional brain systems, and to disturb the timing of brain development more than the final product. Neuroanatomical studies and the associations with teratogens strongly suggest that autism's mechanism includes alteration of brain development soon after conception. This anomaly appears to start a cascade of pathological events in the brain that are significantly influenced by environmental factors. Just after birth, the brains of children with autism tend to grow faster than usual, followed by normal or relatively slower growth in childhood. It is not known whether early overgrowth occurs in all children with autism. It seems to be most prominent in brain areas underlying the development of higher cognitive specialization. Hypotheses for the cellular and molecular bases of pathological early overgrowth include the following:

The Graphene Flagship is a European Union scientific research initiative. With a budget of €1 billion, it is one of the large scale initiatives organized by the Future and Emerging Technologies program, along with the Human Brain Project and the Quantum Technologies Flagship. Through a combined academic-industrial consortium, the research effort attempts to develop technologies which range from basic research to production and system integration, using the unique properties of graphene. There are some critics of this and similar initiatives, arguing that the funding of graphene-related research and innovation is disproportional to estimates of industrial potential. However, advocates for the Graphene Flagship note the merits of the initiative’s wide-ranging, applications-focused research, and the potential for graphene to catalyze innovation and economic growth across sectors and interest areas including biomedical research and health, transport, water safety, energy efficiency, battery and semiconductor development, wearable electronics, digital communications, sustainability and the environment, and space exploration.

A specialized type of CE, affinity capillary electrophoresis (ACE), utilizes intermolecular binding interactions to understand protein-ligand interactions. Pharmaceutical companies use ACE for a multitude of reasons, with one of the main ones being the association/binding constants for drugs and ligands or drugs and certain vehicle systems like micelles. It is a widely used technique because of its simplicity, rapid results, and low analyte usage. The use of ACE can provide specific details in binding, separation, and detection of analytes and is proven to be highly practical for studies in life sciences. Aptamer-based affinity capillary electrophoresis is utilized for the analysis and modifications of specific affinity reagents. Modified aptamers ideally exhibit and high binding affinity, specificity, and nuclease resistance. Ren et al. incorporated modified nucleotides in aptamers to introduce new confrontational features and high affinity interactions from the hydrophobic and polar interactions between IL-1α and the aptamer. Huang et al. uses ACE to investigate protein-protein interactions using aptamers. A α-thrombin binding aptamer was labeled with 6-carboxyfluorescein for use as a selective fluorescent probe and was studied to elucidate information on binding sites for protein-protein and protein-DNA interactions.

Three G states exist and can be categorized as either reversible (quiescent) or irreversible (senescent and differentiated). Each of these three states can be entered from the G phase before the cell commits to the next round of the cell cycle. Quiescence refers to a reversible G state where subpopulations of cells reside in a 'quiescent' state before entering the cell cycle after activation in response to extrinsic signals. Quiescent cells are often identified by low RNA content, lack of cell proliferation markers, and increased label retention indicating low cell turnover. Senescence is distinct from quiescence because senescence is an irreversible state that cells enter in response to DNA damage or degradation that would make a cell's progeny nonviable. Such DNA damage can occur from telomere shortening over many cell divisions as well as reactive oxygen species (ROS) exposure, oncogene activation, and cell-cell fusion. While senescent cells can no longer replicate, they remain able to perform many normal cellular functions. Senescence is often a biochemical alternative to the self-destruction of such a damaged cell by apoptosis. In contrast to cellular senescence, quiescence is not a reactive event but part of the core programming of several different cell types. Finally, differentiated cells are stem cells that have progressed through a differentiation program to reach a mature – terminally differentiated – state. Differentiated cells continue to stay in G and perform their main functions indefinitely.

As the Earth entered a new era, the continents started to move into their modern positions. Australia and South America finally separated from Antarctica while the Indian subplate began its collision into Asia, creating the world's largest mountain range the Himalayas. At the same time, the global average temperature cooled down since Late Cretaceous with a Thermal Maximum at Paleocene-Eocene boundary and Middle Miocene Climatic Optimum. Between these warm episodes were periods of cooling (Oligocene global cooling), where seawater level fell and land bridges between Africa and Eurasia (i.e. Gomphotherium landbridge), and Eurasia and North America (i.e. Bering Land Bridge) were formed.

The supercharger was rather basic in the early models, using a single-stage two-speed design directly geared to the engine (unlike the DB 601's hydraulically clutched version) which led to rather limited altitude performance, in keeping with its intended medium-altitude usage. One key advancement for the 801 was the "Kommandogerät" (command-device), a mechanical-hydraulic unit that automatically adjusted engine fuel flow, propeller pitch, supercharger setting, mixture and ignition timing in response to a single throttle lever, dramatically simplifying engine control. The "Kommandogerät" could be considered to be a precursor to the engine control units used for many vehicles' internal combustion engines of the late 20th and early 21st centuries.

Trade with the Near East and Europe led to strong mercantile empires growing such as the Ethiopian kingdom of Axum and Harla Kingdom. Various states and polities also developed in West Africa including Ife, the Kingdom of Benin, Igbo Ukwu, Djenné-Djenno, Ghana Empire, Bono State and the Ashanti Empire. Bantu peoples in southern Africa built the impressive site of Great Zimbabwe between the 10th and 15th centuries CE. The north of the continent had close cultural and economic ties with the Classical and medieval Mediterranean. Cattle herding became important in the Horn of Africa and huge earthwork enclosures were built to corral the animals. The people of Christian Ethiopia produced impressive rock-cut monolithic churches such as that of St George at Lalibela during the 13th century and the first Portuguese forts appeared soon after this, penetrating as far south as Zambia.

Since 2001, medical personnel working for the Iraqi state health service controlled by Saddam Hussein at the Basra hospital in southern Iraq have reported a sharp increase in the incidence of child leukemia and genetic malformation among babies born in the decade following the Gulf War. Iraqi doctors attributed these malformations to possible long-term effects of DU, an opinion that was echoed by several newspapers. In 2004, Iraq had the highest mortality rate due to leukemia of any country. In 2003, the Royal Society called for Western militaries to disclose where and how much DU they had used in Iraq so that rigorous, and hopefully conclusive, studies could be undertaken out in affected areas. The International Coalition to Ban Uranium Weapons (ICBUW) likewise urged that an epidemiological study be made in the Basra region, as asked for by Iraqi doctors, but no peer-reviewed study has yet been undertaken in Basra.

A sixth nerve palsy, also known as abducens nerve palsy, is a neurological defect that results from a damaged or impaired abducens nerve. This damage can stem from stroke, trauma, tumor, inflammation, and infection. Damage to the abducens nerve by trauma can be caused by any type of trauma that causes elevated intracranial pressure; including hydrocephalus, traumatic brain injury with intracranial bleeding, tumors, and lesions along the nerve at any point between the pons and lateral rectus muscle in orbit. This defect can result in horizontal double vision and reduced lateral movement. The lateral rectus muscle will be denervated and paralyzed and the patient will be unable to abduct the eye. For example, if the left abducens nerve is damaged, the left eye will not abduct fully. While attempting to look straight ahead, the left eye will be deviated medially towards the nose due to the unopposed action of the medial rectus of the eye. Proper function of the lateral rectus is tested clinically by asking the patient to look laterally. Depending on the underlying cause of the lateral rectus palsy, some improvement may occur naturally over time. While the prognosis for a lateral rectus palsy onset by a viral illness is generally positive, the prognosis for an onset of trauma or tumor is quite poor. Ultimately, nerves are not very good at regenerating or healing themselves, so if the damage is severe there will be permanent damage.

Program text, variables, disk buffers and the CP/M operating system itself all had to share the 64 kilobyte address space of the 8080 processor. Typically when first starting MBASIC there would be less than 32 kB memory available for programs and data, even on a machine equipped with a full 64 kilobytes of RAM. Comment lines, prefixed with the codice_1 keyword or an apostrophe, could be placed in the program text but took up valuable memory space, which discouraged BASIC users from fully documenting their code. To allow larger and more complex programs to be run, later versions of MBASIC supported functions that allowed portions of program text to be read in and executed under program control (the "codice_2" and codice_3 statements). No support for "shell" command execution was provided, though this functionality could be duplicated by a determined programmer.

The need for even lighter weight than the T-92 presented the design with a particularly difficult problem; guns capable of defeating modern tanks at reasonable ranges were so large that they demanded a large vehicle to carry them, so large that they couldn't be used as a "light" tank. The use of HEAT rounds instead of conventional penetrating ammunition could address this, but HEAT rounds work better at larger calibers. Gun weight is typically the product of caliber and muzzle velocity, so in the case of the XM551 they sacrificed the muzzle velocity, producing the low-velocity but relatively large-caliber 152 mm M81. HEAT rounds fired by the M81 could defeat any contemporary tank at shorter ranges, but its low velocity made it difficult to use at longer ranges, especially against moving targets. The large low-velocity gun was also ideal for infantry support, where higher performance anti-tank guns would often fire right through soft targets and their small-caliber guns left little room for explosive filler. The M81 would thus be ideal for both direct fire support as well as short-distance anti-tank engagements.

Prediction and validation of the immunodominant epitope/s of HSP90 beta protein has been demonstrated using sera from infertile women having anti-HSP90 autoantibodies. The decapeptide EP6 (380-389)is a major immunogenic epitope of HSP90 followed by EP1 (1-12) and EP8 (488-498). Knowledge of binding epitopes on the autoantigen is necessary to understand the subsequent pathologic events. Predicted 3D structures of these peptides demonstrated that they exist in the loop conformation, which is the most mobile part of the protein. Also, analysis of the sequences of HSP90 beta across several species reveals that EP6 peptide forms a part of a well-conserved motif. A polyclonal antibody generated to the immunodominant epitope- EP6 confirms similar biochemical and cellular immunoreactivity as seen with the patients' sera with anti-HSP90 autoantibodies. The study might generate new tools for the detection of disease-inducing epitopes and a possible therapeutic intervention.

MIPS, an acronym for Microprocessor without Interlocked Pipeline Stages, was a research project conducted by John L. Hennessy at Stanford University between 1981 and 1984. MIPS investigated a type of instruction set architecture (ISA) now called reduced instruction set computer (RISC), its implementation as a microprocessor with very large scale integration (VLSI) semiconductor technology, and the effective exploitation of RISC architectures with optimizing compilers. MIPS, together with the IBM 801 and Berkeley RISC, were the three research projects that pioneered and popularized RISC technology in the mid-1980s. In recognition of the impact MIPS made on computing, Hennessey was awarded the IEEE John von Neumann Medal in 2000 by the Institute of Electrical and Electronics Engineers (IEEE) (shared with David A. Patterson), the Eckert–Mauchly Award in 2001 by the Association for Computing Machinery, the Seymour Cray Computer Engineering Award in 2001 by the IEEE Computer Society, and, again with David Patterson, the Turing Award in 2017 by the ACM.

HVDC DolWin2 is a high voltage direct current (HVDC) link to transmit offshore wind power to the power grid of the German mainland. The project differs from most HVDC systems in that one of the two converter stations is built on a platform in the sea. Voltage-Sourced Converters with DC ratings of 900 MW, ±320 kV are used and the total cable length is 135 km. The project is similar to the HVDC DolWin1 project but has a slightly higher power rating and uses a different design of offshore platform. The platform was designed by Norwegian company Aibel and built by Drydocks World in Dubai and transported to Europe in the summer of 2014 to be fitted out at the Aibel yard in Haugesund in Norway. The platform, which is of a floating, self-installing design not previously used in an HVDC project, sailed out from Haugesund on 1 August 2015 and was installed in the North Sea ten days later.

Only four TPUs were used for inference. The neural network initially knew nothing about Go beyond the rules. Unlike earlier versions of AlphaGo, Zero only perceived the board's stones, rather than having some rare human-programmed edge cases to help recognize unusual Go board positions. The AI engaged in reinforcement learning, playing against itself until it could anticipate its own moves and how those moves would affect the game's outcome. In the first three days AlphaGo Zero played 4.9 million games against itself in quick succession. It appeared to develop the skills required to beat top humans within just a few days, whereas the earlier AlphaGo took months of training to achieve the same level.

Common bracken is a herbaceous perennial plant, deciduous in winter. The large, roughly triangular fronds are produced singly, arising upwards from an underground rhizome, and grow to 0.3–1 m (1–3 ft) tall; the main stem, or stipe, is up to 1 cm (0.4 in) diameter at the base. It dies back to ground level in autumn.The rhizome grows up to 3.5 m (11.5 ft) deep, about 5cm (2 in) in diameter, and up to 15m (49 ft) long. Because it regrows in the spring from an underground rhizome, "P. aquilinum" tends to be found in dense colonies on genetically identical fronds. In the spring as the plant enters its growing cycle, fiddleheads are first sent up from the rhizome. The density and area covered by a single rhizome maximizes that rhizome’s chance of biological success when sending up new growth. The new growth presents as vertical stalks, coiled and covered in silver-gray hairs, that can be several feet in height before unfurling into fronds.

In 1997, a new version of the format was finalized, as VRML97 (also known as VRML2 or VRML 2.0), and became an ISO/IEC standard. VRML97 was used on the Internet on some personal homepages and sites such as "CyberTown", which offered 3D chat using Blaxxun Software, as well as Sony's SAPARi program, which was pre-installed on Vaio computers from 1997 to 2001. The format was championed by SGI's Cosmo Software; when SGI restructured in 1998, the division was sold to the VREAM Division of Platinum Technology, which was then taken over by Computer Associates, which did not develop or distribute the software. To fill the void a variety of proprietary Web 3D formats emerged over the next few years, including Microsoft Chrome and Adobe Atmosphere, neither of which is supported today. VRML's capabilities remained largely the same while realtime 3D graphics kept improving. The VRML Consortium changed its name to the Web3D Consortium, and began work on the successor to VRML—X3D.

Pournelle in May 1983 reported that JRT Pascal 2.0 was "intentionally a nonportable dialect", criticized its error handling, and advised beginners with the language to "stay away from it". "BYTE" editors in April 1983 and January 1984 reported receiving many complaints from readers on slow delivery of JRT Pascal. Pournelle in January 1984 called version 3.0 "a bargain at $29.95. Qualifications: it's a bargain in comparison to a lot of stuff on the market, and its value depends in good part on what you intend to do with it". He reported that 3.0 "has fixed most—not all, but most—of the bugs that plagued the earlier versions", and that "it's cheap for the compiler alone, and you get a bunch of useful utilities with it". Pournelle warned, however, of its "nonstandard features" and that based on Smith's experience and "lots of letters from readers who ordered JRT Pascal and received nothing ... for months", "you must then be prepared to wait" for delivery. Because of JRT, Borland at first had difficulty in persuading customers that it was shipping Turbo Pascal. Bruce F. Webster in August 1985 described JRT Pascal in the magazine as a "fiasco". Jeff Duntemann stated in "PC Magazine" in 1984 that JRT Pascal "was a terrible compiler. Besides doing great harm to the Pascal language definition, it was a bug farm, locking up my CP/M-80 computer several times an evening. Not surprisingly, JRT Systems went bankrupt late last year".

[...] Local authorities have confirmed that one of the two Scaled Composites pilots died during the accident”. This was in strong contrast to public communications previously released concerning the group's successful flights, which had routinely presented pilots, craft, and projects within the same organizational structures, as being "Virgin Galactic" flights or activities of "the Galactic team". The BBC's David Shukman commented that: “Even as details emerge of what went wrong, this is clearly a massive setback to a company hoping to pioneer a new industry of space tourism. Confidence is everything and this will not encourage the long list of celebrity and millionaire customers waiting for their first flight".

The R.E.5 was designed as a reconnaissance biplane using the experience of earlier R.E. series aircraft. It was a two-bay equal-span biplane with a fixed tailskid landing gear, with the wheels supported on skids and powered by a nose-mounted 120 hp (89 kW) Austro-Daimler engine driving a four-bladed propeller. The aircraft had two open cockpits with the observer/gunner in the forward cockpit under the upper wing and the pilot aft. The larger more capable Royal Aircraft Factory R.E.7 was a further development of the design. Some modified single-seat high altitude aircraft were built with extended-span (57 ft 2⅓ in or 17.43 m) upper wings supported by a pair of outward-leaning struts. Other R.E.5s were used for experimentation with airbrakes and for test flying the Royal Aircraft Factory 4 engine.

For chemical storage and air pollution control, the choice is to make multiple tanks of smaller diameters. For example, one of the largest odor control projects in California, the Orange County Sanitation District will utilize 24 vessels total to treat 188,300 cfm (86,200 L/s) of odorous air, with a design of up to 50 ppm of hydrogen sulfide. For an equivalent single vessel to perform as well as the 13 headworks trickling filters, the single vessel would have to be over 36 feet in diameter. This would be impractical due to the high shipping requirements, internal supports, spray nozzles and other internals. Plus this single vessel would not incorporate redundancy for preventive maintenance.

Stanford Mobile Inquiry-based Learning Environment (SMILE) is a mobile learning management software and pedagogical model that introduces an innovative approach to students' education. It is designed to push higher-order learning skills such as applying, analyzing, evaluating, and creating. Instead of a passive, one-way lecture, SMILE engages students in an active learning process by encouraging them to ask, share, answer and evaluate their own questions. Teachers play more of the role of a “coach,” or “facilitator”. The software generates transparent real-time learning analytics so teachers can better understand each student's learning journey, and students acquire deeper insight regarding their own interests and skills. SMILE is valuable for aiding the learning process in remote, poverty-stricken, underserved countries, particularly for cases where teachers are scarce. SMILE was developed under the leadership of Dr. Paul Kim, Wilson Wang, and Rayan Malik.

Stem cell experts consider it unlikely that such large numbers of human egg donations would occur in a developed country because of the unknown long-term public health effects of treating large numbers of healthy young women with heavy doses of hormones in order to induce hyper-ovulation (ovulating several eggs at once). Although such treatments have been performed for several decades now, the long-term effects have not been studied or declared safe to use on a large scale on otherwise healthy women. Longer-term treatments with much lower doses of hormones are known to increase the rate of cancer decades later. Whether hormone treatments to induce hyper-ovulation could have similar effects is unknown. There are also ethical questions surrounding paying for eggs. In general, marketing body parts is considered unethical and is banned in most countries. Human eggs have been a notable exception to this rule for some time.

With the development of plastic materials by organic chemists during the Second World War, the capacitor industry began to replace paper with thinner polymer films. One very early development in film capacitors was described in British Patent 587,953 in 1944. The introduction of plastics in plastic film capacitors was approximately in the following historic order: polystyrene (PS) in 1949, polyethylene terephthalate (PET/"polyester") and cellulose acetate (CA) in 1951, polycarbonate (PC/Lexan) in 1953, polytetrafluoroethylene (PTFE/Teflon) in 1954, polyparylene in 1954, polypropylene (PP) in 1954, polyethylene (PE) in 1958, and polyphenylene sulphide (PPS) in 1967. By the mid-1960s there was a wide range of different plastic film capacitors offered by many, mostly European and US manufacturers. German manufacturers such as WIMA, Roederstein, Siemens and Philips were trend-setters and leaders in a world market driven by consumer electronics.

A Kingdon trap consists of a thin central wire, an outer cylindrical electrode and isolated end cap electrodes at both ends. A static applied voltage results in a radial logarithmic potential between the electrodes. In a Kingdon trap there is no potential minimum to store the ions; however, they are stored with a finite angular momentum about the central wire and the applied electric field in the device allows for the stability of the ion trajectories. In 1981, Knight introduced a modified outer electrode that included an axial quadrupole term that confines the ions on the trap axis. The dynamic Kingdon trap has an additional AC voltage that uses strong defocusing to permanently store charged particles. The dynamic Kingdon trap does not require the trapped ions to have angular momentum with respect to the filament. An Orbitrap is a modified Kingdon trap that is used for mass spectrometry. Though the idea has been suggested and computer simulations performed neither the Kingdon nor the Knight configurations were reported to produce mass spectra, as the simulations indicated mass resolving power would be problematic.

The Quantock Hills are largely formed by rocks of the Devonian Period, which consist of sediments originally laid down under a shallow sea and slowly compressed into solid rock. In the higher north western areas older Early Devonian rocks, known as Hangman Grits, predominate, and can be seen in the exposed rock at West Quantoxhead quarry, which were worked for road building. Further south there are newer Middle and Late Devonian rocks, known as Ilfracombe beds and Morte Slates. These include sandstone and limestone, which have been quarried near Aisholt. At Great Holwell, south of Aisholt, there is a limestone cave, which is the only one in the Devonian limestone of North Devon and West Somerset. The lower fringes around the hills are composed of younger rocks of the Triassic period, these are known as New Red Sandstone rocks which represent the deposits of large river systems that crossed a desert plain, and often contain irregular masses or veins of gypsum, which was worked on the foreshore at Watchet. The scarp is to the west with a dip slope to the east. The west side is cut by combes with broad valleys on the east. The hill tops are open heathland with woods on the slopes.

Sprint events have shorter courses with an expected winning time of 15 minutes and use either a 1:5000 or 1:4000 map. They use lower powered transmitters on the eighty meter band which transmit in sequence for only 12 seconds with the cycle repeating every minute. The IARU Region 1 Rules require 2 sets of 5 transmitters where each set operates on a different frequency. The Morse code transmitted by the second set of transmitters is slightly faster (PARIS 70) than the first set (PARIS 50) to differentiate the two sets. There is also a "spectator" control and a "beacon" control which both operate on different frequencies to the other ten, so four frequencies are used in total. It is possible to combine the spectator control with the beacon control. Competitors start at 2 min intervals and have to visit between 3 and 5 controls out of the first set (according to their age class) before visiting the compulsory spectator control. They then visit the requisite controls from the second set before punching the compulsory beacon control, prior to finishing.

Galen, the prominent Greek physician, surgeon and philosopher in the Roman empire had written on anatomy among other topics, but his work remained largely unchecked until the time of Vesalius. The "Fabrica" rectified some of Galen's worst errors, including the notion that the great blood vessels originated from the liver. Other errors rectified included the idea that the human mandible was in two parts (it is, in fact, in one part) and that men had fewer ribs than women. Disproving this decreased Vesalius' popularity with the Church as it contradicted the Biblical understanding of Adam and Eve. While examining a human corpse, Vesalius discovered that Galen's observations were inconsistent with those of his, due to Galen's use of animal (dog and monkey) cadavers. Overall, Vesalius's use of human corpses allowed him to rectify approximately 300 of Galen's errors. Even with his improvements, however, Vesalius clung to some of Galen's errors, such as the idea that a different type of blood flowed through veins than through arteries. It was not until William Harvey's work on the circulation of the blood ("De Motu Cordis", 1628) that this misconception of Galen's would be rectified in Europe.

Ahlquist was head of the Department of Pharmacology of the University of Georgia School of Medicine, now Georgia Regents University. In 1948 he saw what had escaped Dale in 1906. “The adrenotropic receptors have been considered to be of two classes, those whose action results in excitation and those whose action results in inhibition of the effector cells. Experiments described in this paper indicate that although there are two kinds of adrenotropic receptors they cannot be classified simply as excitatory or inhibitory since each kind of receptor may have either action depending on where it is found.” Ahlquist chose six agonists, including adrenaline, noradrenaline, α-methylnoradrenaline and isoprenaline, and examined their effects on several organs. He found that the six substances possessed two – and only two – rank orders of potency in these organs. For example, the rank order of potency was ″adrenaline > noradrenaline > α-methylnoradrenaline > isoprenaline″ in promoting contraction of blood vessels, but ″isoprenaline > adrenaline > α-methylnoradrenaline > noradrenaline″ in stimulating the heart. The receptor with the first rank order (for example for blood vessel contraction) he called "alpha adrenotropic receptor" (now "α-adrenoceptor" or "α-adrenergic receptor"), while the receptor with the second rank order (for instance for stimulation of the heart, but also for bronchodilation) he called "beta adrenotropic receptor" (now "β-adrenoceptor" or "β-adrenergic receptor"). ″This concept of two fundamental types of receptors is directly opposed to the concept of two mediator substances ("sympathin E" and "sympathin I") as propounded by Cannon and Rosenblueth and now widely quoted as ‘law’ of physiology. ... There is only one adrenergic neuro-hormone, or "sympathin", and that "sympathin" is identical with epinephrine.”

Other CRREL researchers developed ways to upgrade and maintain the research facilities of the U.S. National Science Foundation in Antarctica, including the design and construction of a new South Pole Station and developing criteria to allow modern aircraft to land on snow runways. CRREL staff explored and helped develop a new overland supply route across the Ross Ice Shelf over the Antarctic Range and the Antarctic ice cap to lower the cost of supplying the South Pole Station. In 2016, CRREL research civil engineers designed, built and tested a new snow runway for the McMurdo Station, called "Phoenix". It is designed to accommodate approximately 60 annual sorties of heavy, wheeled transport aircraft.

ADH is derived from a preprohormone precursor that is synthesized in cells in the hypothalamus and stored in vesicles in the posterior pituitary. "Appropriate" ADH secretion is regulated by osmoreceptors on the hypothalamic cells that synthesize and store ADH: plasma hypertonicity activates these receptors, ADH is released into the blood stream, the kidney increases solute-free water return to the circulation, and the hypertonicity is alleviated. "Inappropriate" (increased) ADH secretion causes an "unrelenting increase" in solute-free water ("free water") absorption by the kidneys, with two consequences. First, in the extracellular fluid (ECF) space, there is a dilution of blood solutes, causing hypoosmolality, including a low sodium concentration - hyponatremia. Then virtually simultaneously, in the intracellular space, cells swell, i.e. intracellular volume increases. Swelling of brain cells causes various neurological abnormalities which in severe or acute cases can result in convulsions, coma, and death.

Nearly four years after the release of "Dark Forces II", LucasArts announced at E3 2001 that "Jedi Knight II: Jedi Outcast" would be released in 2002. Unlike previous games in the series, "Jedi Outcast" was not developed in-house by LucasArts, but by Raven Software. The subsequent success of "Outcast" led LucasArts to continue the partnership with Raven, leading to the development of "Jedi Knight: Jedi Academy" a year later; "With the overwhelming success and critical acclaim of "Star Wars: Jedi Outcast", continuing an alliance with Activision and Raven Software was a clear and very easy decision," said then-president of LucasArts, Simon Jeffery. "Jedi Outcast" and "Jedi Academy" are both powered by the "Quake III: Team Arena" game engine, with modifications for the use of a lightsaber and The Force. "Jedi Academy" is the only game in the "Jedi Knight" series that does not give the player control of Katarn at any point. Instead the focus is on Jaden Korr, a student of the Force under Katarn. The decision to change protagonist was made by the developers for gameplay reasons.

The multitaper method overcomes some of the limitations of non-parametric Fourier analysis. When applying the Fourier transform to extract spectral information from a signal, we assume that each Fourier coefficient is a reliable representation of the amplitude and relative phase of the corresponding component frequency. This assumption, however, is not generally valid for empirical data. For instance, a single trial represents only one noisy realization of the underlying process of interest. A comparable situation arises in statistics when estimating measures of central tendency i.e., it is bad practice to estimate qualities of a population using individuals or very small samples. Likewise, a single sample of a process does not necessarily provide a reliable estimate of its spectral properties. Moreover, the naive power spectral density obtained from the signal's raw Fourier transform is a biased estimate of the true spectral content.

Hantz Woodlands, also known as Hantz Farms, is an urban tree farm located on the east side of Detroit. Hantz Woodlands is a project of the Hantz Group, headed by businessman and Detroit-native John Hantz. The project has cleared more than 2,000 vacant city-owned lots and has demolished blighted homes to make way for the hardwood tree farm. It is currently the largest urban tree farm in the US. So far, Hantz Woodlands has invested over 1 million dollars in the community and has planted 25,000 trees over 140 acres. The initiative has been credited with raising home values by 482% and beautifying the surrounding neighborhood. However, controversy and skepticism still surrounds the Hantz Farms project. Critics argue years after acquiring acres of land from Detroit, Hantz could sell the property for development into high-end and commercial real-estate. This action would generate massive profits for the Hantz Group while hurting community cohesion and leaving no payoff for long-time residents.

In about , Ptolemy, the Alexandrian astronomer, sexagesimally subdivided both the mean solar day and the true solar day to at least six places after the sexagesimal point, and he used simple fractions of both the equinoctial hour and the seasonal hour, none of which resemble the modern second. Muslim scholars, including al-Biruni in 1000, subdivided the mean solar day into 24 equinoctial hours, each of which was subdivided sexagesimally, that is into the units of minute, second, third, fourth and fifth, creating the modern second as of the mean solar day in the process. With this definition, the second was proposed in 1874 as the base unit of time in the CGS system of units. Soon afterwards Simon Newcomb and others discovered that Earth's rotation period varied irregularly, so in 1952, the International Astronomical Union (IAU) defined the second as a fraction of the sidereal year. In 1955, considering the tropical year to be more fundamental than the sidereal year, the IAU redefined the second as the fraction of the 1900.0 mean tropical year. In 1956, a slightly more precise value of was adopted for the definition of the second by the International Committee for Weights and Measures, and in 1960 by the General Conference on Weights and Measures, becoming a part of the International System of Units (SI).

In 1925, the Midshipmen Drum and Bugle Corps was formally reestablished. In 1926, "Navy Blue and Gold", composed by organist and choirmaster J. W. Crosley, was first sung in public. It became a tradition to sing this alma mater song at the end of student and alumni gatherings such as pep rallies and football games, and on graduation day. In 1926, Navy won the national collegiate football championship title. In the fall of 1929, the Secretary of the Navy gave his approval for graduates to compete for Rhodes Scholarships. Six graduates were selected for that honor that same year. The Association of American Universities accredited the Naval Academy curriculum on 30 October 1930.

The nundinae were the market days which formed a kind of weekend in Rome, Italy, and some other parts of Roman territory. By Roman inclusive counting, they were reckoned as "ninth days" although they actually occurred every eighth day. Because the republican and Julian years were not evenly divisible into eight-day periods, Roman calendars included a column giving every day of the year a nundinal letter from A to H marking its place in the cycle of market days. Each year, the letter used for the markets would shift along the cycle. As a day when the city swelled with rural plebeians, they were overseen by the aediles and took on an important role in Roman legislation, which was supposed to be announced for three nundinal weeks (between ) in advance of its coming to a vote. The patricians and their clients sometimes exploited this fact as a kind of filibuster, since the tribunes of the plebs were required to wait another three-week period if their proposals could not receive a vote before dusk on the day they were introduced. Superstitions arose concerning the bad luck that followed a nundinae on the nones of a month or, later, on the first day of January. Intercalation was supposedly used to avoid such coincidences, even after the Julian reform of the calendar.

Wythe was born on December 3, 1726, at Chesterville, the plantation operated by three generations of the Wythe family in what was then Elizabeth City County but is now Hampton, Virginia. His maternal great-grandfather was George Keith, a Quaker minister and early opponent of slavery, who returned to the Church of England but was sent back as a missionary to the East Coast before ultimately returning to England. His mother, Margaret Walker of Kecoughtan, a learned woman probably raised as a Quaker, instilled a love of learning in her son. In his later years, Wythe became known for his outdated Quaker dress, as well as his gentle manner, which could cause even a surly dog to "unbend and wag his tail." After the early death of his father, Wythe probably attended grammar school in Williamsburg before beginning legal training in the office of his uncle, Stephen Dewey, in Prince George County.

The AAES membership and leadership are responsible for the development and governance of all comprehensive endocrine surgery fellowships in North America. Many early members of the AAES had gained additional exposure and experience with endocrine surgery via apprenticeships, international fellowships, or surgical oncology fellowships. Recognizing the importance of advanced post-graduate training in endocrine surgery, prominent members created domestic fellowships, most notably, Norman Thompson at the University of Michigan in 1984. The AAES defined a fellowship curriculum in 2004 and sponsored the first match in 2006, supervised by Allan Siperstein. In 2013, a regular accreditation process was established to ensure that all fellowship programs provide robust case volume, complexity, and diversity. As of 2019, there are twenty-three AAES fellowship training programs in comprehensive endocrine surgery. Many fellowship graduates perform a high-volume of endocrine operations early in their careers, and more than 95% experience high job satisfaction. In recent years, endocrine surgery fellowship graduates have joined both academic and community practices equally, increasing patient-access to specialized care and signifying a growing recognition of the specialty.

Ware has made several notable contributions to the field of Human Computer Interaction. In 1993 he developed the concept of “Fish Tank Virtual Reality” to describe a form of virtual reality which is not “immersive”, but rather bounded and contained within the normal working environment. He argued that this mode of viewing allows for a better interactive experience while not blocking access to the rich affordances of the real world. Fish Tank VR allows for the sensation of touch to be simulated using devices such as the Phantom, something which is not possible in immersion VR, except for a localized experience. He also invented the concept of center of workspace interaction. This is a mode of interaction centered on a point just behind the screen in a 3D fish tank environment. Navigation is done by means of selecting points or objects which are automatically translated to this central point where they can be examined by scaling or rotation, or they can be manipulated.

Current research illuminates a variety of mechanisms than can be used to explain elevational diversity gradients. No one factor can be used to explain the presence of diversity gradients within and among taxa; in many cases, we must consider more than one hypothesis or mechanism to fully understand a pattern in elevational diversity. The emerging macroecological experiments along environmental gradients (for example, mountain elevation gradients) are an important tool in ecological research because they allow for the disentangling the effects of individual environmental drivers on biodiversity, the independent effects of which are not easily separated due to their covariance in nature. For instance, microcosm experimental setups in subtropical and subarctic regions (China and Norway, respectively) showed clear segregation of bacterial species along temperature gradients, and interactive effects of temperature and nutrients on biodiversity along mountain elevation gradients. A more expansive research program for mountain biogeography may be extremely beneficial for conservation biologists seeking to understand factors driving biodiversity in known hot spots. Further research and reviews are also needed to address contradictions in the scientific literature, and to identify the extent of interactions between current explanations and hypotheses.

Complex organizations may need large amounts of technical information, which can be distributed among several independent archives. Existing approaches span from "no integration" to "strong integration", that is based on a common database or product model. The so-called weak information systems (WIS) lie somewhere in the middle. Their basic concept is to add to the pre-existing information a new layer of multiple partial models of products and processes, so that it is possible to reuse existing databases, to reduce the development from scratch, and to provide evolutionary paths relevant for the development of the WIS. Each partial model may include specific knowledge and it acts as a way to structure and access the information according to a specific user view.

In July, DART was previewed to the military by BBN Systems and Technologies and the ISX Corporation (now part of Lockheed Martin Advanced Technology Laboratories) in conjunction with the United States Air Force Rome Laboratory. It was proposed in November 1990, with the military immediately demanding that a prototype be developed for testing. A rapid development cycle allowed for a prototype to be developed in eight weeks, which was introduced in 1991 to the USTRANSCOM at the beginning of Operation Desert Storm during the Gulf War.

One more misfolding theory, published in 2004, proposes that β2 microglobulin-free heavy chains of HLA-B27 undergo a facile conformational change in which the C-terminal end of domain 2 (consisting of a long helix) becomes subject to a helix-coil transition involving residues 169–181 of the heavy chain, owing to the conformational freedom newly experienced by domain 3 of the heavy chain when there is no longer any bound light chain (i.e., β2 microglobulin) and owing to the consequent rotation around the backbone dihedral angles of residues 167/168. The proposed conformational transition is thought to allow the newly-generated coiled region (incorporating residues 'RRYLENGKETLQR' which have also been found to be naturally bound to HLA-B27 as a 9-mer peptide) to bind to either the peptide-binding cleft of the same polypeptide chain (in an act of self-display) or to the cleft of another polypeptide chain (in an act of cross-display). Cross-display is proposed to lead to the formation of large, soluble, high molecular weight (HMW), degradation-resistant, long-surviving aggregates of the HLA-B27 heavy chain. Together with any homodimers formed either by cross-display or by a disulfide-linked homodimerization mechanism, it is proposed that such HMW aggregates survive on the cell surface without undergoing rapid degradation, and stimulate an immune response. Three previously noted features of HLA-B27, which distinguish it from other heavy chains, underlie the hypothesis: (1) HLA-B27 has been found to be bound to peptides longer than 9-mers, suggesting that the cleft can accommodate a longer polypeptide chain; (2) HLA-B27 has been found to itself contain a sequence that has also been actually discovered to be bound to HLA-B27, as an independent peptide; and (3) HLA-B27 heavy chains lacking β2 microglobulin have been seen on cell surfaces.

The earliest known realistic concept of motion picture recording was published by Joseph Plateau in a 1849 article about improvements for his fantascope. He had discussed the possibility of the combination of the fantascope and stereoscopic photographs with the inventor of the stereoscope, Charles Wheatstone. They came up with an early conception of stop motion as the best way to obtain the necessary stereoscopic picture sequence. They did not get around to bringing this plan to fruition. Eventually, the idea was communicated to their French publisher and instrumentmaker Jules Duboscq. On 12 November 1852, he filed the "stéréoscope - fantascope ou bioscope" as an addition to his earlier stéréoscope patent. He shortly marketed the device, with little success. The only known extant disc shows a machine in action.

Iceland had among the lowest GDP per capita in Western Europe at the start of the 20th century. According to one assessment by Central Bank of Iceland economists, Post-World War II economic growth has been both significantly higher and more volatile than in other OECD countries. The average annual growth rate of GDP from 1945 to 2007 was about 4%. Studies have shown that the Icelandic business cycle has been largely independent of the business cycle in other industrialised countries. This can be explained by the natural resource-based export sector and external supply shocks. However, the volatility of growth declined markedly towards the end of the century, which may be attributed to the rising share of the services sector, diversifi cation of exports, more solid economic policies, and increased participation in the global economy.According to Reuters, Iceland has had "over 20 financial crises since 1875".

Megaraptorans are incompletely known, and no complete megaraptoran skeleton has been found. However, they still possessed a number of unique features. Their forelimbs were large and strongly built, and the ulna bone had a unique shape in members of the family Megaraptoridae, a subset of megaraptorans which excludes "Fukuiraptor" and "Phuwiangvenator". The first two fingers were elongated, with massive curved claws, while the third finger was small. Megaraptoran skull material is very incomplete, but a juvenile "Megaraptor" described in 2014 preserved a portion of the snout, which was long and slender. Leg bones referred to megaraptorans were also quite slender and similar to those of coelurosaurs adapted for running. Although megaraptorans were thick-bodied theropods, their bones were heavily pneumatized, or filled with air pockets. The vertebrae, ribs, and the ilium bone of the hip were pneumatized to an extent which was very rare among theropods, only seen elsewhere in taxa such as "Neovenator". Other characteristic features include opisthocoelous neck vertebrae and compsognathid-like teeth.

Point-collimation instruments have pinholes that shape the X-ray beam to a small circular or elliptical spot that illuminates the sample. Thus the scattering is centro-symmetrically distributed around the primary X-ray beam and the scattering pattern in the detection plane consists of circles around the primary beam. Owing to the small illuminated sample volume and the wastefulness of the collimation process—only those photons are allowed to pass that happen to fly in the right direction—the scattered intensity is small and therefore the measurement time is in the order of hours or days in case of very weak scatterers. If focusing optics like bent mirrors or bent monochromator crystals or collimating and monochromating optics like multilayers are used, measurement time can be greatly reduced. Point-collimation allows the orientation of non-isotropic systems (fibres, sheared liquids) to be determined.

The pharaoh was the absolute monarch of the country and, at least in theory, wielded complete control of the land and its resources. The king was the supreme military commander and head of the government, who relied on a bureaucracy of officials to manage his affairs. In charge of the administration was his second in command, the vizier, who acted as the king's representative and coordinated land surveys, the treasury, building projects, the legal system, and the archives. At a regional level, the country was divided into as many as 42 administrative regions called nomes each governed by a nomarch, who was accountable to the vizier for his jurisdiction. The temples formed the backbone of the economy. Not only were they places of worship, but were also responsible for collecting and storing the kingdom's wealth in a system of granaries and treasuries administered by overseers, who redistributed grain and goods.

The first two years are called biomedical or pre-clinical cycle. During this time students are instructed in the basic sciences (anatomy, anthropology, biochemistry, biophysics, cell biology, embryology, histology, physiology, pharmacology, biostatistics, etc.). The next three years are the clinical cycle and consist of medical specialties instruction at the faculty and hospital practice. The last year consists of an internship from 3 months each of surgery, internal medicine, gynecology and pediatrics. To acquire the license from the government to practice medicine, at the end of internship must be done a Honorary Mandatory Socialist Service (SSSRO) in a rural area of the country during at least three months.

Several studies have shown that the interaction of Slit with its receptors is crucial in regulating the processes involved with the formation of organs. As previously discussed, these interactions play a key role in cell migration. Not surprisingly then, this gene has been found expressed during the development of tightly regulated tissues, such as the heart, lungs, gonads, and ovaries. For example, in early development of the heart tube in "Drosophila", Slit and two of its Robo receptors guide migrating cardioblasts and pericardial cells in the dorsal midline. In addition, research on mice has shown that "Slit3" and its interaction with "Robo1" may be crucial to the development and maturation of lung tissue. Similarly, the expression of "Slit3" is upregulated when aligning airway epithelium with endothelium. Due to its regulating function in tissue development, absence or mutations in the expression of these genes can result in abnormalities of these tissues. Several studies in mice and other vertebrates have shown that this deficit results in death almost immediately after birth.

The whole of the Obama plan "envisions stationing existing SM-3 interceptors as part of the Aegis Ballistic Missile Defense on Aegis-equipped ships in the Mediterranean Sea and elsewhere by 2011, and on land in Central Europe by 2015, as part of a European Phased Adaptive Approach (EPAA). A more advanced system would be deployed by 2018, including to Poland as EPAA phase 3, and a more-advanced generation (EPAA phase 4), theoretically capable of shooting down intercontinental missiles, by 2020." Phase 4 was cancelled, however, in March 2013, triggering some speculation that it was a concession promised by Obama to President Medvedev before the 2012 United States presidential election; the allegations of Russian influence over this decision were however denied by the Pentagon.

In 1999 a two-stage modification was reported that allowed the controlled formation of silica particles with small holes. The process is undertaken at low pH in the presence of a surface-active molecule. The hydrolysis step is completed with the formation of a microemulsion before adding sodium fluoride to start the condensation process. The non-ionic surfactant is burned away to produce empty pores, increasing the surface area and altering the surface characteristics of the resulting particles, allowing for much greater control over the physical properties of the material. Development work has also been undertaken for larger pore structures such as macroporous monoliths, shell-core particles based on polystyrene, cyclen, or polyamines, and carbon spheres.

In 2000, another American scientist, Bradley C. Edwards, suggested creating a long paper-thin ribbon using a carbon nanotube composite material. He chose the wide-thin ribbon-like cross-section shape rather than earlier circular cross-section concepts because that shape would stand a greater chance of surviving impacts by meteoroids. The ribbon cross-section shape also provided large surface area for climbers to climb with simple rollers. Supported by the NASA Institute for Advanced Concepts, Edwards' work was expanded to cover the deployment scenario, climber design, power delivery system, orbital debris avoidance, anchor system, surviving atomic oxygen, avoiding lightning and hurricanes by locating the anchor in the western equatorial Pacific, construction costs, construction schedule, and environmental hazards.

His first wife died in October 1923, and in August of the next year Schoenberg married Gertrud Kolisch (1898–1967), sister of his pupil, the violinist Rudolf Kolisch. They had three children: Nuria Dorothea (born 1932), Ronald Rudolf (born 1937), and Lawrence Adam (born 1941). Gertrude Kolisch Schoenberg wrote the libretto for Schoenberg's one-act opera "Von heute auf morgen" under the pseudonym Max Blonda. At her request Schoenberg's (ultimately unfinished) piece, "Die Jakobsleiter" was prepared for performance by Schoenberg's student Winfried Zillig. After her husband's death in 1951 she founded Belmont Music Publishers devoted to the publication of his works. Arnold used the notes G and E (German: Es, i.e., "S") for "Gertrud Schoenberg", in the "Suite", for septet, Op. 29 (1925). (see musical cryptogram).

The academy is both an honorific membership organization and a policy research organization. Its members, elected on the basis of their professional achievement and commitment to service, serve without compensation in the conduct of studies and other activities on matters of significance to health. Election to active membership is both an honor and a commitment to serve in Institute affairs. The bylaws specify that no more than 80 new members shall be elected annually, including 10 from outside the United States. The announcement of newly elected members occurs at the Annual Meeting in October. As of October 20, 2015, the number of regular members plus international and emeritus members is 2,012. An unusual diversity of talent among NAM members is assured by the charter stipulation that at least one-quarter be selected from outside the health professions, from such fields as the natural, social, and behavioral sciences, as well as law, administration, engineering, and the humanities.

The four azide halides FN, ClN, BrN, and IN have all been made, and all contain purely covalent azide-halide bonds making them extremely sensitive. The gas phase reaction between F and HN will produce FN but the F needs to be diluted in an inert gas, and fast mixing needs to be avoided to FN isn’t formed. Chlorine azide is also a gas and can be produced by bubbling dilute chlorine gas through a solution of NaN. However, chlorine azide tends to explode spontaneously even at reduced temperatures. Bromine azide is a liquid but is still equally treacherous. The NaN used must be dry as BrN hydrolyzes in water. Similarly, the iodine azide is moisture sensitive and can be made from ICl and AgN as a solid. However, since AgN can only be handled safely when moist, drying agent is normally added to the reaction mixture to prevent hydrolysis of the final product. Both BrN and IN find use in synthesis a convenient way to make azidiridines and azirines. The chlorine, bromine, and iodine azides have been characterized in the solid state. The chlorine azide has strong Cl-Cl interactions and is comparable to the herringbone arrangement of other halogen structures. In contrast, the bromine and iodine azides prefer intermolecular X-N interactions to give a helical structure for the BrN and flat chains for IN.

The narrowness of the cerebral aqueduct and foramina means that they can become blocked, for example, by blood following a hemorrhagic stroke. As cerebrospinal fluid is continually produced by the choroid plexus within the ventricles, a blockage of outflow leads to increasingly high pressure in the lateral ventricles. As a consequence, this commonly leads in turn to hydrocephalus. Medically one would call this post-haemorrhagic acquired hydrocephalus, but is often referred to colloquially by the layperson as "water on the brain". This is an extremely serious condition regardless of the cause of blockage. An endoscopic third ventriculostomy is a surgical procedure for the treatment of hydrocephalus in which an opening is created in the floor of the third ventricle using an endoscope placed within the ventricular system through a burr hole. This allows the cerebrospinal fluid to flow directly to the basal cisterns, thereby bypassing any obstruction. A surgical procedure to make an entry hole to access any of the ventricles is called a ventriculostomy. This is done to drain accumulated cerebrospinal fluid either through a temporary catheter or a permanent shunt.

Concerns about the repeated small explosions, the atmospheric venting of radioactive gasses, and the possibility of larger explosions led to a -radius evacuation around the plant. During the early days of the accident workers were temporarily evacuated at various times for radiation safety reasons. At the same time, sea water that had been exposed to the melting rods was returned to the sea heated and radioactive in large volumes for several months until recirculating units could be put in place to repeatedly cool and re-use a limited quantity of water for cooling. The earthquake damage and flooding in the wake of the tsunami hindered external assistance. Electrical power was slowly restored for some of the reactors, allowing for automated cooling.
