Fasting
Fasting is the abstention from eating and sometimes drinking. From a purely physiological context, "fasting" may refer to the metabolic status of a person who has not eaten overnight (see " Breakfast"), or to the metabolic state achieved after complete digestion and absorption of a meal. Metabolic changes in the fasting state begin after absorption of a meal (typically 3–5 hours after eating). A diagnostic fast refers to prolonged fasting from 1 to 100 hours (depending on age) conducted under observation to facilitate the investigation of a health complication, usually hypoglycemia. Many people may also fast as part of a medical procedure or a check-up, such as preceding a colonoscopy or surgery, or before certain medical tests. Intermittent fasting is a technique sometimes used for weight loss that incorporates regular fasting into a person's dietary schedule. Fasting may also be part of a religious ritual, often associated with specifically scheduled fast days, as determ ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

FAST TCP
FAST TCP (also written FastTCP) is a TCP congestion avoidance algorithm especially targeted at long-distance, high latency links, developed at the Netlab, California Institute of Technology and now being commercialized by FastSoft. FastSoft was acquired by Akamai Technologies in 2012. FastTCP is compatible with existing TCP algorithms, requiring modification only to the computer which is sending data. Name The name FAST is a recursive acronym for FAST AQM Scalable TCP, where AQM stands for Active Queue Management, and TCP stands for Transmission Control Protocol. Principles of operation The role of congestion control is to moderate the rate at which data is transmitted, "congestion", according to the capacity of the network and the rate at which other users are transmitting. Like TCP Vegas, FAST TCP uses queueing delay instead of loss probability as a congestion signal. Most current congestion control algorithms detect congestion and slow down when they discover that packe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Speed
In everyday use and in kinematics, the speed (commonly referred to as ''v'') of an object is the magnitude of the change of its position over time or the magnitude of the change of its position per unit of time; it is thus a scalar quantity. The average speed of an object in an interval of time is the distance travelled by the object divided by the duration of the interval; the instantaneous speed is the limit of the average speed as the duration of the time interval approaches zero. Speed is not the same as velocity. Speed has the dimensions of distance divided by time. The SI unit of speed is the metre per second (m/s), but the most common unit of speed in everyday usage is the kilometre per hour (km/h) or, in the US and the UK, miles per hour (mph). For air and marine travel, the knot is commonly used. The fastest possible speed at which energy or information can travel, according to special relativity, is the speed of light in a vacuum ''c'' = metres per second ...

Five-hundred-meter Aperture Spherical Telescope
The Five-hundred-meter Aperture Spherical radio Telescope (FAST; ), nicknamed Tianyan (, lit. "Sky's/Heaven's Eye"), is a radio telescope located in the Dawodang depression (), a natural basin in Pingtang County, Guizhou, southwest China. FAST has a diameter dish constructed in a natural depression in the landscape. It is the world's largest filled-aperture radio telescope and the second-largest single-dish aperture, after the sparsely-filled RATAN-600 in Russia. It has a novel design, using an active surface made of 4,500 metal panels which form a moving parabola shape in real time. The cabin containing the feed antenna, suspended on cables above the dish, can move automatically by using winches to steer the instrument to receive signals from different directions. It observes at wavelengths of 10 cm to 4.3 m. Construction of FAST began in 2011. It observed first light in September 2016. After three years of testing and commissioning, it was declared fully operatio ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Feedback Arc Set
In graph theory and graph algorithms, a feedback arc set or feedback edge set in a directed graph is a subset of the edges of the graph that contains at least one edge out of every cycle in the graph. Removing these edges from the graph breaks all of the cycles, producing a directed acyclic graph, an acyclic subgraph of the given graph. The feedback arc set with the fewest possible edges is the minimum feedback arc set and its removal leaves the maximum acyclic subgraph; weighted versions of these optimization problems are also used. If a feedback arc set is minimal, meaning that removing any edge from it produces a subset that is not a feedback arc set, then it has an additional property: reversing all of its edges, rather than removing them, produces a directed acyclic graph. Feedback arc sets have applications in circuit analysis, chemical engineering, deadlock resolution, ranked voting, ranking competitors in sporting events, mathematical psychology, ethology, and graph drawin ...

Fixing America's Surface Transportation Act
The Fixing America's Surface Transportation Act or the FAST Act is a funding and authorization bill to govern United States federal surface transportation spending. It was passed by Congress on December 3, 2015, and President Barack Obama signed it on the following day. The vote was 359–65 in the House of Representatives and 83–16 in the United States Senate. History The bill was introduced to the House by Rodney Davis () as the "Hire More Heroes Act of 2015" on January 6, 2015. The $305 billion, five-year bill is funded without increasing transportation user fees. (The federal gas tax was last raised in 1993.) Instead, funds were generated through changes to passport rules, Federal Reserve Bank dividends, and privatized tax collection. In Section 6021, Congress asked the Transportation Research Board (TRB) to conduct a study of the actions needed to upgrade and restore the Interstate Highway System to fulfill its role as a crucial national asset, serving the needs of ...

Fluorescence-activating And Absorption-shifting Tag
FAST (''Fluorescence-Activating and absorption-Shifting Tag'') is a small, genetically-encoded, protein tag which allows for fluorescence reporting of proteins of interest. Unlike natural fluorescent proteins and derivates such as GFP or mCherry, FAST is not fluorescent by itself. It can bind selectively a fluorogenic chromophore derived from 4-hydroxybenzylidene rhodanine (HBR), which is itself non fluorescent unless bound. Once bound, the pair of molecules goes through a unique fluorogen activation mechanism based on two spectroscopic changes, increase of fluorescence quantum yield and absorption red shift, hence providing high labeling selectivity. The FAST-fluorogen reporting system can be used in fluorescence microscopy, flow cytometry and any other fluorometric method to explore the living world: biosensors, protein trafficking. FAST, a small 14 kDa protein, was engineered from the photoactive yellow protein (PYP) by directed evolution. It was reported for the first time ...

Federation Against Software Theft
The Federation Against Software Theft (FAST) is a not-for-profit organisation, formed in 1984 with the aim of eliminating copyright infringement of software in the UK. FAST was the world's first Anti-piracy organisation to work on protecting the copyrights of software publishers. Initially concentrating on lobbying parliament to revise Copyright law, FAST also prosecutes organisations and individuals for copyright infringement on behalf of its members and publicises the legal penalties and security risks. Prior to the agreement with FAST, Investors in Software were a not-for-profit organisation limited by guarantee with a mission to support and advance professionalism in Software Asset Management and related IT asset management, to enable individuals and organisations to improve effectiveness and efficiency. As a direct result of their work the ISO SAM ISO 19770 standard was successfully launched in May 2006. History In September 2008 FAST and Investors in Software signed an ex ...

Faceted Application Of Subject Terminology
Faceted Application of Subject Terminology (FAST) is a general use controlled vocabulary based on the Library of Congress Subject Headings (LCSH). FAST is developed as a part of WorldCat by OCLC, Inc., with the goal of making subject cataloging less costly and easier to implement in online contexts. FAST headings separate topical data from non-topical data, such as information about a document's form, chronological coverage, or geographical coverage. Unlike LCSH headings, which are pre-coordinated (multiple terms are linked together by the cataloger in a specific order, e.g. "United States -- History"), FAST headings are post-coordinated (terms are singly assigned, so the user can mix and match, e.g. "United States" and "History"). Use OCLC has been developing FAST since 1998, and originally intended the system to describe Web resources in simple metadata schemata, particularly Dublin Core. FAST separates headings into eight distinct facets: topical, geographic, personal name, corp ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Focused Assessment With Sonography For Trauma
Focused assessment with sonography in trauma (commonly abbreviated as FAST) is a rapid bedside ultrasound examination performed by surgeons, emergency physicians, and paramedics as a screening test for blood around the heart (pericardial effusion) or abdominal organs (hemoperitoneum) after trauma. There is also the extended FAST (eFAST) which includes some additional ultrasound views to assess for pneumothorax. The four classic areas that are examined for free fluid are the perihepatic space (including Morison's pouch or the hepatorenal recess), perisplenic space, pericardium, and the pelvis. With this technique it is possible to identify the presence of intraperitoneal or pericardial free fluid. In the context of traumatic injury, this fluid will usually be due to bleeding. Indications Reasons a FAST or eFAST would be performed would be: #Blunt abdominal trauma #Penetrating abdominal trauma #Blunt thoracic trauma #Penetrating thoracic trauma #Undifferentiated shock (low blo ...
