National Kidney Registry
The National Kidney Registry (NKR) is a national registry in the United States listing kidney donors and recipients in need of a kidney transplant. NKR facilitates over 450 " Kidney Paired Donation" (KPD) or "Paired Exchange" transplants annually. More than one-third of potential living kidney donors who want to donate their kidney to a friend or family member cannot because of blood type or antibody incompatibility. Historically, these donors would be turned away and the patient would lose the opportunity to receive a life-saving kidney transplant. KPD overcomes donor-recipient incompatibility by swapping kidneys between multiple donor-recipient pairs, and connecting them in longer chains, as well as taking an altruistic non-directed donor, and start chains of kidney transplants. What the NKR does is consolidate the incompatible pairs of donors and recipients from transplant centers all over the United States, into a single registry, and facilitate the transplant process.

Nonprofit
A nonprofit organization (NPO) or non-profit organisation, also known as a non-business entity, not-for-profit organization, or nonprofit institution, is a legal entity organized and operated for a collective, public or social benefit, in contrast with an entity that operates as a business aiming to generate a profit for its owners. A nonprofit is subject to the non-distribution constraint: any revenues that exceed expenses must be committed to the organization's purpose, not taken by private parties. An array of organizations are nonprofit, including some political organizations, schools, business associations, churches, social clubs, and consumer cooperatives. Nonprofit entities may seek approval from governments to be tax-exempt, and some may also qualify to receive tax-deductible contributions, but an entity may incorporate as a nonprofit entity without securing tax-exempt status. Key aspects of nonprofits are accountability, trustworthiness, honesty, and openness to eve ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Red-eye Flight
In commercial aviation, a red-eye flight is a flight scheduled to depart at night and arrive the next morning. Another definition of a red-eye flight is one that takes place overnight but does not provide enough time for passengers to get a full night's sleep. The term "red-eye" derives from the symptom of having red eyes, which can be caused by fatigue. Causes and utilities For the airline, overnight flights will enable more use of aircraft that would otherwise be idle at night. For airports, it may be rational to divert the stream of passengers away from peak hours. In major airports, the capacity for flight operations during daytime may be fully exhausted, and the price of airport slots may be higher at peak hours. For passengers, the benefits and disadvantages are more subjective. Many will perceive it difficult to arrive well-rested after a night flight, especially if it is at odd hours or too short to fit into a full night's sleep. However, the traffic to and from the ai ...

Cryopreservation
Cryo-preservation or cryo-conservation is a process where Organism, organisms, organelles, cell (biology), cells, Biological tissue, tissues, extracellular matrix, Organ (anatomy), organs, or any other biological constructs susceptible to damage caused by unregulated chemical kinetics are preserved by cooling to very low temperatures (typically using solid carbon dioxide or using liquid nitrogen). At low enough temperatures, any Enzyme, enzymatic or chemical activity which might cause damage to the biological material in question is effectively stopped. Cryopreservation methods seek to reach low temperatures without causing additional damage caused by the formation of ice crystals during freezing. Traditional cryopreservation has relied on coating the material to be frozen with a class of molecules termed cryoprotectants. New methods are being investigated due to the inherent toxicity of many cryoprotectants. Cryoconservation of animal genetic resources is done with the intentio ...

Order (exchange)
An order is an instruction to buy or sell on a trading venue such as a stock market, bond market, commodity market, financial derivative market or cryptocurrency exchange. These instructions can be simple or complicated, and can be sent to either a broker or directly to a trading venue via direct market access. There are some standard instructions for such orders. Market order A market order is a buy or sell order to be executed immediately at the ''current'' ''market'' prices. As long as there are willing sellers and buyers, market orders are filled. Market orders are used when certainty of execution is a priority over the price of execution. A market order is the simplest of the order types. This order type does not allow any control over the price received. The order is filled at the best price available at the relevant time. In fast-moving markets, the price paid or received may be quite different from the last price quoted before the order was entered. A market order may be ...

Expert System
In artificial intelligence, an expert system is a computer system emulating the decision-making ability of a human expert. Expert systems are designed to solve complex problems by reasoning through bodies of knowledge, represented mainly as if–then rules rather than through conventional procedural code. The first expert systems were created in the 1970s and then proliferated in the 1980s. Expert systems were among the first truly successful forms of artificial intelligence (AI) software. An expert system is divided into two subsystems: the inference engine and the knowledge base. The knowledge base represents facts and rules. The inference engine applies the rules to the known facts to deduce new facts. Inference engines can also include explanation and debugging abilities. History Early development Soon after the dawn of modern computers in the late 1940s and early 1950s, researchers started realizing the immense potential these machines had for modern society.

Algorithm
In mathematics and computer science, an algorithm () is a finite sequence of rigorous instructions, typically used to solve a class of specific Computational problem, problems or to perform a computation. Algorithms are used as specifications for performing calculations and data processing. More advanced algorithms can perform automated deductions (referred to as automated reasoning) and use mathematical and logical tests to divert the code execution through various routes (referred to as automated decision-making). Using human characteristics as descriptors of machines in metaphorical ways was already practiced by Alan Turing with terms such as "memory", "search" and "stimulus". In contrast, a Heuristic (computer science), heuristic is an approach to problem solving that may not be fully specified or may not guarantee correct or optimal results, especially in problem domains where there is no well-defined correct or optimal result. As an effective method, an algorithm ca ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
