The closer to 1, the more concentrated power is. There is a general but not strict correlation between concentration and polarity. It is rare to find a result over 0.5, but a result between 0.4 and 0.5 usually indicates a unipolar system, while a result between 0.2 and 0.4 usually indicated a bipolar or multipolar system.
At the North American T2 rate (6.312 Mbit/s), bipolar violations are inserted if 6 or more consecutive zeros occur. This line code is called bipolar with six-zero substitution (B6ZS), and replaces 6 consecutive zeros with the pattern "0VB0VB". Depending on the polarity of the preceding mark, that could be 0+−0−+ or 0−+0+−.
A bipolar signal may have a two-state non-return-to-zero (NRZ) or a three-state return-to-zero (RZ) binary coding scheme. A bipolar signal is usually symmetrical with respect to zero amplitude, i.e. the absolute values of the positive and negative signal states are nominally equal. Contrast with unipolar encoding where one state is zero ...
The cell bodies of invertebrate unipolar neurons are often located around the edges of the neuropil, in the so-called cell-body rind. [3] Most neurons in the central nervous systems of vertebrates, including mammals, are multipolar. [4] In multipolar neurons, multiple processes extend from the cell body including dendrites and axons.
The general structure of the dendrite is used to classify neurons into multipolar, bipolar and unipolar types. Multipolar neurons are composed of one axon and many dendritic trees. Pyramidal cells are multipolar cortical neurons with pyramid-shaped cell bodies and large dendrites that extend towards the surface of the cortex (apical dendrite ...
(1) Soma, (2) Basal dendrite, (3) Apical dendrite, (4) Axon, (5) Collateral axon. One of the main structural features of the pyramidal neuron is the conic shaped soma , or cell body, after which the neuron is named.
If those multipoles are coupled by some exchange mechanisms, those multipoles could tend to have some ordering as conventional spin 1/2 Heisenberg problem. Except the multipolar ordering, many hidden order phenomena are believed closely related to the multipolar interactions [11] [14] [15]
[1] [2] [3] Kleist coined the terms unipolar (‘einpolig’) and bipolar (‘zweipolig’) that are now used in the concepts of unipolar depression and bipolar disorder. [4] His main publications were in the field of neurology, and he is particularly known for his work on the localisation of function in the cerebral cortex of man including ...
