https://en.wikipedia.org/wiki/Robert%20S.%20Boyer | Robert Stephen Boyer is an American retired professor of computer science, mathematics, and philosophy at The University of Texas at Austin. He and J Strother Moore invented the Boyer–Moore string-search algorithm, a particularly efficient string searching algorithm, in 1977. He and Moore also collaborated on the Boy... |
https://en.wikipedia.org/wiki/Speaker%20terminal | A speaker terminal is a type of electrical connector often used for interconnecting speakers and audio power amplifiers.
The terminals are used in pairs with each of the speaker cable's two wires being connected to one terminal in the pair. Since speaker connections are polarized, the terminals are typically color-co... |
https://en.wikipedia.org/wiki/Site-specific%20recombinase%20technology | Site-specific recombinase technologies are genome engineering tools that depend on recombinase enzymes to replace targeted sections of DNA.
History
In the late 1980s gene targeting in murine embryonic stem cells (ESCs) enabled the transmission of mutations into the mouse germ line, and emerged as a novel option to st... |
https://en.wikipedia.org/wiki/Wi-Fi%20calling | Wi-Fi calling refers to mobile phone voice calls and data that are made over IP networks using Wi-Fi, instead of the cell towers provided by cellular networks. Using this feature, compatible handsets are able to route regular cellular calls through a wireless LAN (Wi-Fi) network with broadband Internet, while seamlessl... |
https://en.wikipedia.org/wiki/EncFS | EncFS is a Free (LGPL) FUSE-based cryptographic filesystem. It transparently encrypts files, using an arbitrary directory as storage for the encrypted files.
Two directories are involved in mounting an EncFS filesystem: the source directory, and the mountpoint. Each file in the mountpoint has a specific file in the so... |
https://en.wikipedia.org/wiki/Gravity%20of%20Earth | The gravity of Earth, denoted by , is the net acceleration that is imparted to objects due to the combined effect of gravitation (from mass distribution within Earth) and the centrifugal force (from the Earth's rotation).
It is a vector quantity, whose direction coincides with a plumb bob and strength or magnitude is g... |
https://en.wikipedia.org/wiki/Optical%20mineralogy | Optical mineralogy is the study of minerals and rocks by measuring their optical properties. Most commonly, rock and mineral samples are prepared as thin sections or grain mounts for study in the laboratory with a petrographic microscope. Optical mineralogy is used to identify the mineralogical composition of geologica... |
https://en.wikipedia.org/wiki/Equations%20for%20a%20falling%20body | A set of equations describing the trajectories of objects subject to a constant gravitational force under normal Earth-bound conditions. Assuming constant acceleration g due to Earth’s gravity, Newton's law of universal gravitation simplifies to F = mg, where F is the force exerted on a mass m by the Earth’s gravitatio... |
https://en.wikipedia.org/wiki/Grapefruit%E2%80%93drug%20interactions | Some fruit juices and fruits can interact with numerous drugs, in many cases causing adverse effects. The effect is most studied with grapefruit and grapefruit juice, but similar effects have been observed with certain other citrus fruits.
The effect was first discovered accidentally in 1991, when a test of drug inte... |
https://en.wikipedia.org/wiki/TreeDL | Tree Description Language (TreeDL) is a computer language for description of strictly-typed tree data structures and operations on them. The main use of TreeDL is in the development of language-oriented tools (compilers, translators, etc.) for the description of a structure of abstract syntax trees.
Tree description c... |
