Earthquake Precursor
Earthquake prediction is a branch of the science of seismology concerned with the specification of the time, location, and magnitude of future earthquakes within stated limits, and particularly "the determination of parameters for the ''next'' strong earthquake to occur in a region". Earthquake prediction is sometimes distinguished from '' earthquake forecasting'', which can be defined as the probabilistic assessment of ''general'' earthquake hazard, including the frequency and magnitude of damaging earthquakes in a given area over years or decades. Not all scientists distinguish "prediction" and "forecast", but the distinction is useful. Prediction can be further distinguished from earthquake warning systems, which upon detection of an earthquake, provide a real-time warning of seconds to neighboring regions that might be affected. In the 1970s, scientists were optimistic that a practical method for predicting earthquakes would soon be found, but by the 1990s continuing failure ...

Gehrlein Precursor
The Gehrlein Precursor is an American, high-wing, single seat glider designed by Larry Gehrlein in 1965 and assembled from Schweizer Aircraft parts.Said, Bob: ''1983 Sailplane Directory, Soaring Magazine'', page 28 and 43. Soaring Society of America November 1983. USPS 499-920 Design and development There was just one Schweizer 1-23C built and it was owned and modified by Gehrlein. The aircraft was crashed and rebuilt with new 1-23D wings. The 1-23C's damaged wings were rebuilt and formed the basis for the Precursor. The fuselage for the Precursor started life as a 1963 model Schweizer 1-26A. The two components were reworked by Gehrlein and his two sons, Rod and Jay, in 1965. They took the 1-26A fuselage and mounted the wings from the Schweizer 1-23C, modifying the fuselage, which had mounted the original 1-26 wings in the mid position to accept the 1-23C wings in the high position. The resulting aircraft is registered with the Federal Aviation Administration in the ''Expe ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precursor (bird)
''"Precursor"'' is a controversial prehistoric bird genus from the Early Eocene. It was established based on fossils found in England, including in the famous London Clay deposits. Three species are included in the genus: ''"P." parvus'', the type species, ''"P." magnus'', and ''"P." litorum,'' all named by Colin Harrison and Cyril Walker in 1977. These remains were originally considered to be members of the Charadriiformes, more specifically the earliest representatives of the Glareolidae (pratincoles and coursers). However, several authors have since found this interpretation to be dubious, with the lack of measurements and contradictory wording making the original description's conclusions difficult to verify. At least some of the material, namely the paratype humerus of ''"P." parvus'', has been re-interpreted as belonging to the Pseudasturidae (or Halcyornithidae), a group of stem-parrot Parrots, also known as psittacines (), are birds of the roughly 398 species in 92 ...

Precursor Cell
In cell biology, a precursor cell, also called a blast cell or simply blast, is a partially differentiated cell, usually referred to as a unipotent cell that has lost most of its stem cell properties. A precursor cell is also known as a progenitor cell but progenitor cells are multipotent. Precursor cells are known as the intermediate cell before they become differentiated after being a stem cell. Usually, a precursor cell is a stem cell with the capacity to differentiate into only one cell type. Sometimes, ''precursor cell'' is used as an alternative term for unipotent stem cells. In embryology, precursor cells are a group of cells that later differentiate into one organ. A blastoma is any cancer created by malignancies of precursor cells. Precursor cells, and progenitor cells, have many potential uses in medicine. , there is research being done to use these cells to build heart valves, blood vessels and other tissues, by using blood and muscle precursor, or progenitor c ...

Halo (series)
''Halo'' is a military science fiction media franchise, originally developed by Bungie and currently managed and developed by 343 Industries, part of Microsoft's Xbox Game Studios.

The latest main game, ''Halo Infinite'', was released in 2021. ''Combat Evolved'' started life as a real-time strategy game, before morphing into a first-person shooter and releasing as an exclusive on Microsoft's new Xbox (console), Xbox video game console after Bungie was acquired by the company. Bungie regained its independence in 2007, releasing additional ''Halo'' games through 2010. Microsoft established 343 Industries to direct the franchise going forward, and has produced games itself and in partnership with other studios. ''Combat Evolved'' was a critical and commercial success, serving as the Xbox's "killer app" and cementing Mic ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precursors Of Film
Precursors of film are concepts and devices that have much in common with the later art and techniques of cinema. Precursors of film are often referred to as precinema, or 'pre-cinema'. Terms like these are disliked by several historians, partly because they seem to devalue the individual qualities of these media by presenting them as a small step in the development of a later invention. For instance: the flip book, zoetrope and phenakistiscope are very tactile devices that allow study and play by manipulating the motion by hand, while the projected image in cinema is intangible. Such devices as the zoetrope were not replaced by cinema: they were still used after the breakthrough of film. Furthermore, many early media examples are also part of a tradition that not only shaped cinema, but also home video, video games, computer-generated imagery, virtual reality and much more. The study of early media devices is also part of a wider and less teleological approach called media archaeo ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Precursor (physics)
Precursors are characteristic wave patterns caused by dispersion of an impulse's frequency components as it propagates through a medium. Classically, precursors precede the main signal, although in certain situations they may also follow it. Precursor phenomena exist for all types of waves, as their appearance is only predicated on the prominence of dispersion effects in a given mode of wave propagation. This non-specificity has been confirmed by the observation of precursor patterns in different types of electromagnetic radiation (microwaves, visible light, and terahertz radiation) as well as in fluid surface waves and seismic waves. History Precursors were first theoretically predicted in 1914 by Arnold Sommerfeld for the case of electromagnetic radiation propagating through a neutral dielectric in a region of normal dispersion.See L. Brillouin, ''Wave Propagation and Group Velocity'' (Academic Press, New York, NY, 1960), Ch. 1. Sommerfeld's work was expanded in the following ye ...
