HDF5
Hierarchical Data Format (HDF) is a set of file formats (HDF4, HDF5) designed to store and organize large amounts of data. Originally developed at the U.S. National Center for Supercomputing Applications, it is supported by The HDF Group, a non-profit corporation whose mission is to ensure continued development of HDF5 technologies and the continued accessibility of data stored in HDF. In keeping with this goal, the HDF libraries and associated tools are available under a liberal, BSD-like license for general use. HDF is supported by many commercial and non-commercial software platforms and programming languages. The freely available HDF distribution consists of the library, command-line utilities, test suite source, Java interface, and the Java-based HDF Viewer (HDFView). The current version, HDF5, differs significantly in design and API from the major legacy version HDF4. Early history The quest for a portable scientific data format, originally dubbed AEHOO (All Encompassing ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Subwavelength-diameter Optical Fibre
A subwavelength-diameter optical fibre (SDF or SDOF) is an optical fibre whose diameter is less than the wavelength of the light being propagated through it. An SDF usually consists of long thick parts (same as conventional optical fibres) at both ends, transition regions (tapers) where the fibre diameter gradually decreases down to the subwavelength value, and a subwavelength-diameter waist, which is the main acting part. Due to such a strong geometrical confinement, the guided electromagnetic field in an SDF is restricted to a single mode called ''fundamental''. Name There is no general agreement on how these optical elements are to be named; different groups prefer to emphasize different properties of such fibres, sometimes even using different terms. The names in use include subwavelength waveguide, subwavelength optical wire, subwavelength-diameter silica wire, subwavelength diameter fibre taper, (photonic) wire waveguide, photonic wire, photonic nanowire, optical nanowires ...

Silver Diammine Fluoride
Silver diammine fluoride (SDF), also known as silver diamine fluoride in most of the dental literature, (although this is a chemical misnomer) is a topical medication used to treat and prevent dental caries (tooth decay) and relieve dentinal hypersensitivity. It is a colorless (most products) or blue-tinted (Advantage Arrest), odourless liquid composed of silver, ammonium and fluoride ions at a pH of 10.4 (most products) or 13 (Riva Star). Ammonia compounds reduce the oxidative potential of SDF, increase its stability and helps to maintain a constant concentration over a period of time, rendering it safe for use in the mouth. Silver and fluoride ions possess antimicrobial properties and are used in the remineralization of enamel and dentin on teeth for preventing and arresting dental caries. SDF is also known as diammine silver fluoride, silver fluoride, and silver ammonium fluoride. It is frequently spelled "silver diamine fluoride" (with one ''m''); however, this is a misnom ...

Soquel Demonstration State Forest
Soquel Demonstration State Forest (SDSF or SDF) is one of eight Cal Fire operated Demonstration State Forests totaling 71,000 acres. Collectively, the forests represent the most common forest types in the state. The State Forests grow approximately 75 million board feet yearly and harvest an average of 30 million board feet of timber each year, enough to build 3,000 single-family homes. Revenue from these harvests fund a variety of the Department's Resource Management Programs. In addition, the forests provide research and demonstration projects on forest management, while providing public recreation opportunities, fish and wildlife habitat, and watershed protection. The Board of Forestry and Fire Protection (Board) policy provides that the State Forests shall be used for experimentation to determine the economic feasibility of artificial reforestation, and to demonstrate the productive and economic possibilities of good forest practices toward maintaining forest crop land in a ...

Louisville International Airport
Louisville Muhammad Ali International Airport , formerly known as simply Louisville International Airport, is a civil-military airport in Louisville in Jefferson County, Kentucky. The airport covers and has three runways. Its IATA airport code, SDF, is based on the airport's former name, Standiford Field. It has no regularly-scheduled international passenger flights, but it is a port of entry, as it handles numerous international cargo flights through the United Parcel Service's worldwide air hub through its airline, often referred to as UPS Worldport. Over 4.2 million passengers and over 5.7 billion pounds (2.89 million tons) of cargo passed through the airport in 2019. It is also the second-busiest in the United States in terms of cargo traffic, and fourth-busiest for such in the world. The National Plan of Integrated Airport Systems for 2011–2015 categorized it as a "primary commercial service" airport since it has over 10,000 passenger boardings (enplanements) per year. ...

Socialist Democratic Federation (Japan)
The (SDF), also referred to in Japanese by the shortened , was a Japanese political party that existed from 1978 to 1994. It was formed from the merger of the and the . History The Socialist Democratic Federation was a splinter party of the Japan Socialist Party (JSP). Its emergence followed a series of upheavals involving this left-wing, opposition political party, which began with the establishment of the Democratic Socialist Party in January 1960 and the later reemergence of the Japan Communist Party (JCP). The exodus of its membership is partly attributed to the perceived pro-Communist tendencies on the part of the JSP leadership during the political crisis involving the revision of Japan's Mutual Security Treaty with the United States. Experts also blame a diminished public support for the socialist party, particularly in big cities. The process continued until the next decade when the Shaminren finally split off from JSP. By this time, JSP was already in severe disarr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Social Democratic Forum
The Social Democratic Forum (, SDF) was a short-lived political group in Hong Kong formed by the radical faction of the Democratic Party. It consisted mostly the "Young Turks" faction of the Democratic Party which took a more pro-grassroots and street action approaches. It ceased to exist in April 2002 when most members joined The Frontier. History It was formed in the background of the intra-party struggles in the Democratic Party in 2000. The factional struggle began in the 1998 Democratic Party leadership election where the Young Turks who believed in more pro-grassroots and radical approaches launched a "coup d'etat", supporting trade unionist Lau Chin-shek to run against incumbent Vice-Chairman Anthony Cheung who was leader of the Meeting Point faction who believed in pro-middle class and moderate methods. The intra-party struggle intensified when Andrew To proposed to put the minimum wage legislation on the 2000 Legislative Council election platform but was defeated by the ...
