Random Checkpoint
A random checkpoint is a military and police tactic. In a military context, checkpoints involve the setup of a hasty roadblock by mobile truck- or armored vehicle-mounted infantry to disrupt unauthorized or unwanted movement or military activity and to check for valid identification and search for contraband, fugitives, or weapons that are not permitted in civilian hands. Random checkpoints are set up to achieve surprise, as opposed to known permanently located checkpoints, which suspects could circumvent. They are often established in locations where they cannot be observed by approaching traffic until it is too late to withdraw and escape without being observed. Patrol car-equipped police units regularly use random checkpoints to detect drivers who are suspected of impaired driving. Police also use hastily set up roadblocks to check cars and car trunks when they are pursuing an armed and dangerous fugitive. As with military checkpoints, sobriety checkpoints and fugitive roadb ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Checkpoint (rapid HIV Testing Facility)
Checkpoint was the name of the first rapid HIV testing facility in the Netherlands. This project, run on a voluntary basis, was based in Amsterdam. From 21 June 2002 until its closure on 27 June 2008 almost 5000 people opted for a Checkpoint HIV test. The rapid HIV testing employed by Checkpoint was for the whole of its existence unique in the Netherlands, because it was at that time not used by the various local health authorities. Such authorities and physicians employed the regular HIV antibody test and clients had to wait 1 or 2 weeks for the result. When an increasing number of local health authorities began using the rapid HIV test, Checkpoint had served its purpose and could be closed down. The rapid HIV test enabled a reliable outcome to be generated within 15 to 20 minutes, which in practice lowered the threshold for such testing. Because in this way more people opted for testing, more HIV-positive people could be reached. A clear advantage is that the diagnosis is ma ...

Checkpoint (video Gaming)
A saved game (also called a game save, savegame, savefile, save point, or simply save) is a piece of digitally stored information about the progress of a player in a video game. From the earliest games in the 1970s onward, game platform hardware and memory improved, which led to bigger and more complex computer games, which, in turn, tended to take more and more time to play them from start to finish. This naturally led to the need to store in some way the progress, and how to handle the case where the player received a " game over". More modern games with a heavier emphasis on storytelling are designed to allow the player many choices that impact the story in a profound way later on, and some game designers do not want to allow more than one save game so that the experience will always be "fresh". Game designers allow players to prevent the loss of progress in the game (as might happen after a game over). Games designed this way encourage players to 'try things out', and on r ...

Security Checkpoint
Civilian checkpoints or security checkpoints are distinguishable from border or frontier checkpoints in that they are erected and enforced within contiguous areas under military or paramilitary control. Civilian checkpoints have been employed within conflict-ridden areas all over the world to monitor and control the movement of people and materials in order to prevent violence. They have also been used by police during peacetime to help counter terrorism. Contemporary examples Though practices and enforcement vary, checkpoints have been used in: * Airports and other transportation hubs across the world, including those managed by the TSA in the United States. * Post World War II checkpoints in Germany * The former Yugoslavia during the Yugoslav Wars. * Northern Ireland by the Official IRA, Provisional IRA, Irish National Liberation Army, and Real IRA as well as by the British Army, Royal Ulster Constabulary, Police Service of Northern Ireland and also by the Ulster Defense ...

Border Checkpoint
A border checkpoint is a location on an international border where travelers or goods are inspected and allowed (or denied) passage through. Authorization often is required to enter a country through its borders. Access-controlled borders often have a limited number of checkpoints where they can be crossed without legal sanctions. Arrangements or treaties may be formed to allow or mandate less restrained crossings (e.g. the Schengen Agreement). Land border checkpoints (land ports of entry) can be contrasted with the customs and immigration facilities at seaports, international airports, and other ports of entry. Checkpoints generally serve two purposes: * To prevent entrance of individuals who are either undesirable (e.g. criminals or others who pose threats) or simply unauthorized to enter. * To prevent entrance of goods that are illegal or subject to restriction, or to collect tariffs. Checkpoints are usually staffed by a uniformed service (sometimes referred to as customs ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Cell Cycle Checkpoint
Cell cycle checkpoints are control mechanisms in the eukaryotic cell cycle which ensure its proper progression. Each checkpoint serves as a potential termination point along the cell cycle, during which the conditions of the cell are assessed, with progression through the various phases of the cell cycle occurring only when favorable conditions are met. There are many checkpoints in the cell cycle, but the three major ones are: the G1 checkpoint, also known as the Start or restriction checkpoint or Major Checkpoint; the G2/M checkpoint; and the metaphase-to-anaphase transition, also known as the spindle checkpoint. Progression through these checkpoints is largely determined by the activation of cyclin-dependent kinases by regulatory protein subunits called cyclins, different forms of which are produced at each stage of the cell cycle to control the specific events that occur therein. Background All living organisms are the products of repeated rounds of cell growth and division ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Restriction Point
The restriction point (R), also known as the Start or G1/S checkpoint, is a cell cycle checkpoint in the G1 phase of the animal cell cycle at which the cell becomes "committed" to the cell cycle, and after which extracellular signals are no longer required to stimulate proliferation. The defining biochemical feature of the restriction point is the activation of G1/S- and S-phase cyclin-CDK complexes, which in turn phosphorylate proteins that initiate DNA replication, centrosome duplication, and other early cell cycle events. It is one of three main cell cycle checkpoints, the other two being the G2-M DNA damage checkpoint and the spindle checkpoint. History Originally, Howard Martin Temin showed that chicken cells reach a point at which they are committed to replicate their DNA and are not dependent on extracellular signals. About 20 years later, in 1973, Arthur Pardee demonstrated that a single restriction point exists in G1. Previously, G1 had been defined simply as the tim ...

In 1959, he bought the Kemsley Group, a purchase that eventually gave him control of the '' Sunday Times''. He separately acquired the ''Times'' in 1967. He moved into the airline business in 1965, when he acquired Britanni ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Transaction Checkpoint
Transaction processing is a way of computing that divides work into individual, indivisible operations, called transactions. A transaction processing system (TPS) is a software system, or software/ hardware combination, that supports transaction processing. History The first transaction processing system was SABRE, made by IBM for American Airlines, which became operational in 1964. Designed to process up to 83,000 transactions a day, the system ran on two IBM 7090 computers. SABRE was migrated to IBM System/360 computers in 1972, and became an IBM product first as '' Airline control Program (ACP)'' and later as '' Transaction Processing Facility (TPF)''. In addition to airlines TPF is used by large banks, credit card companies, and hotel chains. The Hewlett-Packard NonStop system (formerly Tandem NonStop) was a hardware and software system designed for ''Online Transaction Processing (OLTP)'' introduced in 1976. The systems were designed for transaction processing and prov ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Application Checkpointing
Checkpointing is a technique that provides fault tolerance for computing systems. It basically consists of saving a snapshot of the application's state, so that applications can restart from that point in case of failure. This is particularly important for long running applications that are executed in failure-prone computing systems. Checkpointing in distributed systems In the distributed computing environment, checkpointing is a technique that helps tolerate failures that otherwise would force long-running application to restart from the beginning. The most basic way to implement checkpointing, is to stop the application, copy all the required data from the memory to reliable storage (e.g., parallel file system) and then continue with the execution. In case of failure, when the application restarts, it does not need to start from scratch. Rather, it will read the latest state ("the checkpoint") from the stable storage and execute from that. While there is ongoing debate on wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
