https://en.wikipedia.org/wiki/Gummel%E2%80%93Poon%20model | The Gummel–Poon model is a model of the bipolar junction transistor. It was first described in an article published by Hermann Gummel and H. C. Poon at Bell Labs in 1970.
The Gummel–Poon model and modern variants of it are widely used in popular circuit simulators such as SPICE. A significant effect that the Gummel–P... |
https://en.wikipedia.org/wiki/Global%20Sea%20Level%20Observing%20System | Established in 1985, The Global Sea Level Observing System (GLOSS) is an Intergovernmental Oceanographic Commission (IOC) program whose purpose is to measure sea level globally for long-term climate change studies. The program's purpose has changed since the 2004 Indian Ocean earthquake and the program now collects rea... |
https://en.wikipedia.org/wiki/Transistor%20model | Transistors are simple devices with complicated behavior. In order to ensure the reliable operation of circuits employing transistors, it is necessary to scientifically model the physical phenomena observed in their operation using transistor models. There exists a variety of different models that range in complexity a... |
https://en.wikipedia.org/wiki/Lucas%20cell | A Lucas cell is a type of scintillation counter. It is used to acquire a gas sample, filter out the radioactive particulates through a special filter and then count the radioactive decay. The inside of the gas chamber is coated with ZnS(Ag) - a chemical that emits light when struck by alpha particles. A photomultipli... |
https://en.wikipedia.org/wiki/Dogs%20%28Fouling%20of%20Land%29%20Act%201996 | The Dogs (Fouling of Land) Act 1996 is an Act of the Parliament of the United Kingdom. The purpose of the Act was to create a criminal offence if a dog defecates at any time on designated land and a person who is in charge of the dog at that time fails to remove the faeces from the land forthwith.
It was repealed by C... |
https://en.wikipedia.org/wiki/Stress%20migration | Stress migration is a failure mechanism that often occurs in integrated circuit metallization (aluminum, copper). Voids form as result of vacancy migration driven by the hydrostatic stress gradient. Large voids may lead to open circuit or unacceptable resistance increase that impedes the IC performance. 'Stress migrati... |
https://en.wikipedia.org/wiki/Clue%20cell | Clue cells are epithelial cells of the vagina that get their distinctive stippled appearance by being covered with bacteria. The etymology behind the term "clue" cell derives from the original research article from Gardner and Dukes describing the characteristic cells. The name was chosen for its brevity in describing ... |
https://en.wikipedia.org/wiki/Pharyngeal%20groove | A pharyngeal groove (or branchial groove, or pharyngeal cleft) is made up of ectoderm unlike its counterpart the pharyngeal pouch on the endodermal side.
The first pharyngeal groove produces the external auditory meatus (ear canal). The rest (2, 3, and 4) are overlapped by the growing 2nd pharyngeal arch, and form the... |
https://en.wikipedia.org/wiki/Pharyngeal%20pouch%20%28embryology%29 | In the embryonic development of vertebrates, pharyngeal pouches form on the endodermal side between the pharyngeal arches. The pharyngeal grooves (or clefts) form the lateral ectodermal surface of the neck region to separate the arches.
Specific pouches
First pouch
The endoderm lines the future auditory tube (Pharyng... |
https://en.wikipedia.org/wiki/Posterior%20inferior%20cerebellar%20artery | The posterior inferior cerebellar artery (PICA) is the largest branch of the vertebral artery. It is one of the three main arteries that supply blood to the cerebellum, a part of the brain. Blockage of the posterior inferior cerebellar artery can result in a type of stroke called lateral medullary syndrome.
