On the remainder of the clear channels, the dominant ( class 1 ) -- B stations are protected as described above, and the relatively small number of secondary ( class 2 ) ) stations permitted to operate on these channels at night are required to operate directionally and/or with reduced power so as to protect the class 1, stations.

The formula provides the GoS ( grade of service ) which is the probability P < sub > b </ sub > that a new call arriving at the circuit group is rejected because all servers ( circuits ) are busy: B ( E, m ) when E Erlang of traffic are offered to m trunks ( communication channels ).

The 144 kbit / s payload rate is broken down into two 64 kbit / s bearer channels (' B ' channels ) and one 16 kbit / s signaling channel (' D ' channel or delta channel ).

An E1 is 30 ' B ' channels of 64 kbit / s, one ' D ' channel of 64 kbit / s and a timing and alarm channel of 64 kbit / s.

A PRI has 23 ' B ' channels and 1 ' D ' channel for signalling ( Japan uses a circuit called a J1, which is similar to a T1 ).

PRI uses out of band signaling which provides the 23 B channels with clear 64 kb for voice and data and one 64 kb ' D ' channel for signaling and messaging.

Most B channels can carry a 64 kbit / s signal, but some were limited to 56K because they traveled over RBS lines.

X. 25 can be carried over the B or D channels of a BRI line, and over the B channels of a PRI line.

This allowed a user to have a constant multi-link PPP connection to the internet over X. 25 on the D channel, and brought up one or two B channels as needed.

In ISDN, there are two types of channels, B ( for " bearer ") and D ( for " data ").

B channels are used for data ( which may include voice ), and D channels are intended for signaling and control ( but can also be used for data ).

Basic Rate Interface ( BRI ), also called basic rate access ( BRA ) — consists of two B channels, each with bandwidth of 64 kbit / s, and one D channel with a bandwidth of 16 kbit / s.

Primary Rate Interface ( PRI ), also called primary rate access ( PRA ) in Europe — contains a greater number of B channels and a D channel with a bandwidth of 64 kbit / s.

The number of B channels for PRI varies according to the nation: in North America and Japan it is 23B + 1D, with an aggregate bit rate of 1. 544 Mbit / s ( T1 ); in Europe, India and Australia it is 30B + 1D, with an aggregate bit rate of 2. 048 Mbit / s ( E1 ).

Another alternative ISDN configuration can be used in which the B channels of an ISDN BRI line are bonded to provide a total duplex bandwidth of 128 kbit / s.

Using bipolar with eight-zero substitution encoding technique, call data is transmitted over the data ( B ) channels, with the signaling ( D ) channels used for call setup and management.

Bearer channels may also be multiplexed into what may be considered single, higher-bandwidth channels via a process called B channel BONDING, or via use of Multi-Link PPP " bundling " or by using an H0, H11, or H12 channel on a PRI.

Vitamin B < sub > 12 </ sub > deficiency may cause, among several neurological abnormalities, overlapping cerebellar and sensory ataxia.

In humans, the cell surface is bare around the B cell receptors for several hundred nanometers, which further isolates the BCRs from competing influences.

The Phoenix has several guidance modes and achieves its longest range by using mid-course updates from the F-14A / B AWG-9 radar ( APG-71 radar in the F-14D ) as it climbs to cruise between and at close to Mach 5.

Modern guitarists such as Ramón Montoya, have introduced other positions: Montoya himself started to use other chords for the tonic in the modern Dorian sections of several palos ; F sharp for tarantas, B for granaínas and A flat for the minera.

Hierax tried to defeat king Attalus I of Pergamum ( 241 – 197 BC ), but instead, the Hellenized cities united under Attalus's banner, and his armies inflicted several severe defeats upon them in about 232 B. C., forcing them to settle permanently and to confine themselves to the region to which they had already given their name.

In 1991 the team folded and was reborn as Verona FC, regularly moving to and fro between Serie A and Serie B for several seasons.

The album peaked at # 9 on Billboard magazine's Top R & B / Hip-Hop Albums and at # 14 on the Billboard 200, spawning several singles including " Gotta Lotta Love ", " I Ain't New To This " and " 99 Problems " – which would later inspire Jay-Z to record a version with new lyrics in 2003.

Brown and his fellow Famous Flame, Bobby Byrd, recruited several members of the Cincinnati band, The Pacemakers, which included Bootsy Collins and his brother Phelps " Catfish " Collins, and, using some remaining members of Brown's 1960s road band and other newer musicians, dubbed the band simply as The J. B .' s.

By the end of his contract with producer Hal B. Wallis, Lewis had several productions of his own under his belt.

Progestin-only EC is available as a dedicated emergency contraceptive product under many names worldwide, including: in the U. S., Canada and Honduras as Plan B ; in Great Britain, Ireland, Australia, New Zealand, Portugal and Italy as Levonelle ; in South Africa as Escapelle ; in 44 nations including France, most of Western Europe, India, and several countries in Africa, Asia and Latin America as NorLevo ; and in 44 nations including most of Eastern Europe, Mexico and many other Latin American countries, Portugal, Australia and New Zealand, Israel, China, Hong Kong, Taiwan and Singapore as Postinor-2.

The bulk were of more recent vintage, and were dubbed Linear B. Evans spent the next several decades trying to decipher both, to no avail.

Besides folic acid ( Vitamin B < sub > 9 </ sub >) Marmite has useful quantities of several other vitamins, even in small servings.

On the other hand, several of the sources James B. Stewart used for Den of Thieves told him that Milken often tried to get a higher markup on trades than was permitted at the time.

The 356, however, had several evolutionary stages, A, B, and C, while in production, and many Volkswagen parts were replaced by Porsche-made parts.

The lyrics quote from several of the poem's verses, and the tracks ' highly stylized and heavily reverberated production values and pop mysticism have made it a favorite of samplers, beat-diggers, and fans of psychedelic jazz and R & B.

In 1935 the company introduced several new models including the Model " B " Electric Spanish guitar which is considered the first solid body electric guitar.

In mid-1968 Askin famously became embroiled in a media controversy over the reporting of several words spoken to the United States Chamber of Commerce lunch in Sydney on 32 July 1968 ( also the day Opposition Leader Renshaw resigned, to be replaced by Pat Hills ), in which he spoke of the October 1966 state visit by United States President Lyndon B. Johnson.

Each ballot can therefore be viewed as a small " delta " which separates two groups of candidates, or a single-pair of ranks ( e. g. if a ballot indicates that A & C are approved and B & D are not, the ballot can be considered to convey the ranking >).

Cytokines are substances that can activate cytotoxic T lymphocytes ( CTL ), antibody-secreting B cells, macrophages, and other particles.

Tumor antigens can also be on the surface of the tumor in the form of, for example, a mutated receptor, in which case they will be recognized by B cells.

T cells cannot bind native antigens, but require that they be processed by APCs, whereas B cells can be activated by native ones.

This can be expressed as A over B.

However, one can choose the index of the first element by an appropriate choice of the base address B.

It has been reported that some effects can be had from consuming the caapi vine alone, but that DMT-containing plants ( such as Psychotria ) remain inactive when drunk as a brew without a source of monoamine oxidase inhibitor ( MAOI ) such as B. caapi.

Antibodies can occur in two physical forms, a soluble form that is secreted from the cell, and a membrane-bound form that is attached to the surface of a B cell and is referred to as the B cell receptor ( BCR ).

The BCR is only found on the surface of B cells and facilitates the activation of these cells and their subsequent differentiation into either antibody factories called plasma cells, or memory B cells that will survive in the body and remember that same antigen so the B cells can respond faster upon future exposure.

Surface immunoglobulin ( Ig ) is attached to the membrane of the effector B cells by its transmembrane region, while antibodies are the secreted form of Ig and lack the trans membrane region so that antibodies can be secreted into the bloodstream and body cavities.

The adenovirus E1B-55K protein and the hepatitis B virus HBx protein are examples of viral proteins that can perform such a function.

Where A has a greater priority than B according to the Cahn-Ingold-Prelog priority rule, the configuration of the axial chirality can be determined by considering the top, then the bottom.

Antares B can be observed with a small telescope for a few seconds during lunar occultations while Antares itself is hidden by the Moon ; it was discovered by Johann Tobias Bürg during one such occultation on April 13, 1819.

It exists in four major polymorphs: α, β, γ and T. Whereas α, β and T phases are based on B < sub > 12 </ sub > icosahedra, the γ-phase can be described as a rocksalt-type arrangement of the icosahedra and B < sub > 2 </ sub > atomic pairs.

Thus, the vector space B ( X, Y ) can be given the operator norm

If X is a Banach space and K is the underlying field ( either the real or the complex numbers ), then K is itself a Banach space ( using the absolute value as norm ) and we can define the continuous dual space as X ′ = B ( X, K ), the space of continuous linear maps into K.

Toxins that can be used as weapons include ricin, staphylococcal enterotoxin B, botulinum toxin, saxitoxin, and many mycotoxins.

Bézier curves are also used in the time domain, particularly in animation and interface design, e. g., a Bézier curve can be used to specify the velocity over time of an object such as an icon moving from A to B, rather than simply moving at a fixed number of pixels per step.

Writing B < sub > P < sub > i </ sub >, P < sub > j </ sub >, P < sub > k </ sub ></ sub >( t ) for the quadratic Bézier curve defined by points P < sub > i </ sub >, P < sub > j </ sub >, and P < sub > k </ sub >, the cubic Bézier curve can be defined as a linear combination of two quadratic Bézier curves:

Behaviorism insisted on working only with what can be seen or manipulated and in the early views of John B. Watson, a founder of the field, nothing was inferred as to the nature of the entity that produced the behavior.
