Complement Receptor
A complement receptor is a membrane-bound receptor belonging to the complement system, which is part of the innate immune system. Complement receptors bind effector protein fragments that are produced in response to antigen-antibody complexes or damage-associated molecules. Complement receptor activation contributes to the regulation of inflammation, leukocyte extravasation, and phagocytosis; it also contributes to the adaptive immune response. Different complement receptors can participate in either the classical complement pathway, the alternative complement pathway, or both. Expression and function White blood cells, particularly monocytes and macrophages, express complement receptors on their surface. All four complement receptors can bind to fragments of complement component 3 or complement component 4 coated on pathogen surface, but the receptors trigger different downstream activities. Complement receptor (CR) 1, 3, and 4 function as opsonins which stimulate phagocytos ...

Control Register
A control register is a processor register which changes or controls the general behavior of a CPU or other digital device. Common tasks performed by control registers include interrupt control, switching the addressing mode, paging control, and coprocessor control. Control registers in x86 series CR0 The CR0 register is 32 bits long on the 386 and higher processors. On x64 processors in long mode, it (and the other control registers) is 64 bits long. CR0 has various control flags that modify the basic operation of the processor. Register CR0 is the 32 Bit version of the old Machine Status Word (MSW) register. The MSW register was expanded to the Control Register with the appearance of the i386 processor. CR1 Reserved, the CPU will throw a # UD exception when trying to access it. CR2 Contains a value called Page Fault Linear Address (PFLA). When a page fault occurs, the address the program attempted to access is stored in the CR2 register. CR3 Used when virtual addr ...

100 Gigabit Ethernet
40 Gigabit Ethernet (40GbE) and 100 Gigabit Ethernet (100GbE) are groups of computer networking technologies for transmitting Ethernet frames at rates of 40 and 100 gigabits per second (Gbit/s), respectively. These technologies offer significantly higher speeds than 10 Gigabit Ethernet. The technology was first defined by the IEEE 802.3ba-2010 standard and later by the 802.3bg-2011, 802.3bj-2014, 802.3bm-2015, and 802.3cd-2018 standards. The standards define numerous port types with different optical and electrical interfaces and different numbers of optical fiber strands per port. Short distances (e.g. 7 m) over twinaxial cable are supported while standards for fiber reach up to 80 km. Standards development On July 18, 2006, a call for interest for a High Speed Study Group (HSSG) to investigate new standards for high speed Ethernet was held at the IEEE 802.3 plenary meeting in San Diego. The first 802.3 HSSG study group meeting was held in September 2006. In June 2 ...

Concentration Ratio
In economics, concentration ratios are used to quantify market concentration and are based on companies' market shares in a given industry. Market share can be defined as a firm's proportion of total sales in an industry, a firm's market capitalisation as a percentage of total industry market capitalisation or any other metric which conveys the size and dominance of a company relative to its competitors. A concentration ratio (CR) is the sum of the percentage market shares of (a pre-specified number of) the largest firms in an industry. An n-firm concentration ratio is a common measure of market structure and shows the combined market share of the n largest firms in the market. For example, where n = 5, CR5 defines the combined market share of the five largest firms in an industry. Competition economists and competition authorities typically employ concentration ratios (CRn) and the Herfindahl-Hirschman Index (HHI) as measures of market concentration.

CR Postcode Area
The CR postcode area, also known as the Croydon postcode area, is a group of eight postcode districts in England, within ten post towns. These cover parts of southern Greater London and north-east Surrey. The main sorting office is in Croydon, and the area served includes most of the London Borough of Croydon, the southeastern part of the London Borough of Merton and small parts of the London Boroughs of Sutton and Bromley. Most of CR3 and CR6 cover the northern part of the Tandridge district of Surrey, and the southern part of CR5 covers a small part of the borough of Reigate and Banstead. Croydon was the second town, after Norwich, to have experimental postcodes, introduced in 1966. This trialled the postcode area CRO (letter 'O'), while Norwich used NOR for its equivalent. It was decided that the outward (first) part of a postcode should be alphanumerical, so CRO became CR0 (with a zero) and NOR became NR1. The CR1 postcode has not been introduced, making CR the only postco ...
