The object of the present invention is to provide a method and an apparatus for the exponentiation of large binary numbers in a residue class modulo N which is particularly suited for encoding and decoding digitally-represented messages and in which the exponentiation comprises repeated squaring/multiplication cycles with a residue formation.
Residue Formation C (mod N) An algorithm which approximately calculates the residue C mod N is employed for the further processing of the results of the multiplication.
The residue formation is then a multiplication of a known vector and that part of the modified inverse of the matrix which is determined for the residue formation.

Anchor residue motifs of HLA class-I-binding peptides analyzed by the direct binding of synthetic peptides to HLA class I alpha chains.With B27 anchor motifs, an interlocus cross-reactivity with A3 and A31 was seen.
Several peptides, even though they carried A2 or B27 major anchor residue motifs, failed to bind to the relevant alpha chains, suggesting that the presence of a primary anchor residue motif is necessary for HLA class-I-peptide binding but is not by itself sufficient to guarantee binding.
The binding characteristics of the primary anchor residue motifs reported for HLA-A2 (A*0201, A*0205) and HLA-B27 (B*2705) alleles were investigated by a direct binding assay of the pertinent synthetic peptides to HLA class I alpha chains derived from a panel of HLA homozygous B- cell lines of various HLA phenotypes, including four A2 subtypes.

 Ribbon Style Editor
A ribbon residue class is defined by which atoms control the path of the ribbon and which atoms are considered part of the backbone (mainchain atoms).
The path of the ribbon is controlled by two atoms per residue: the guide atom sets ribbon location (the path is smoothed over five successive residues), and the orientation atom sets the plane of the ribbon.
There is also a nucleic acid rotated class, which differs from the nucleic acid class only in that the option to rotate the ribbon is on.

 GAP (RCWA) - Chapter 2: Residue Class-Wise Affine Mappings
Apart from the restrictions imposed by the condition that the image of any residue class r(m) under f must be a subset of R and that one cannot divide by 0, the coefficients a_r(m), b_r(m) and c_r(m) can be any ring elements.
The class shift nu_r(m) is the rcwa mapping of Z which maps n in r(m) to n + m and fixes Z \ r(m) pointwise.
The class transposition tau_r_1(m_1),r_2(m_2) is an rcwa mapping of Z of order 2 which interchanges the disjoint residue classes r_1(m_1) and r_2(m_2) of Z and fixes the complement of their union pointwise.

 [prg] 4 An Example -- Residue Class Rings   (Site not responding. Last check: 2007-09-17)
Section A Second Attempt to Implement Elements of Residue Class Rings shows how this can be done in our example, and Section Compatibility of Residue Class Rings with Prime Fields, the question of further compatibility of the new objects with known GAP objects is discussed.
Note that the functions there assumed that their arguments were residue classes, and the user was responsible not to call them with other arguments.
Probably it is not necessary to emphasize that with the approach of Section A First Attempt to Implement Elements of Residue Class Rings, installing methods for existing operations is usually not possible or at least not recommended.

 Residue frequency profile   (Site not responding. Last check: 2007-09-17)
This tool determines which residues in a given kinase are rare and restricted to only a few sequences.
In other words, you can get a measure of how "weird" the kinase is and which points in the sequence distinguish it from the proteins in the rest of the database or in a specified subset.
The output is a graphical representation of the sequences along with the frequency coefficients on the scale from 0 to 100, where 0 means that the residue at this position is 100% conserved in all kinases, and 100 meaning that only this kinase has this residue at the current position.

For disordered residues (that have no alpha atom) it may be set to an alternate index so that applicatons may still draw backbone traces through the residue.

 [prg] 5 An Example -- Residue Class Rings
And when we have implemented the arithmetic operations for matrices of residue classes, we might be interested in domain operations such as computing the order of a matrix group over Z/4Z, a Sylow 2 subgroup, and so on.
So the only interesting relation between the families of two residue classes is equality; binary arithmetic operations with two residue classes will be admissible only if their families are equal.
By the way, also groups of (invertible) residue classes can be formed, but this may be of minor interest.

A cohomological approach to properties of the norm residue symbol in higher dimensional class field theory, by Robert A. Bell
In earlier work the author proved that the Vostokov symbol of an n dimensional mixed characteristic local field commutes with the Vostokov symbol of an n-1 dimensional mixed characteristic local field.Here the author generalizes this theorem to the case of a regular local ring A subject to certain conditions.
This is done by using Kato's reformulation of the Vostokov symbol as a map from Milnor K-theory to Fontaine-Messing cohomology.

Create the residue class ring Z/mZ, where m is the integer corresponding to the factorization sequence Q. This is more efficient than creating the ring by m alone, since the factorization Q will be stored so it can be reused later.
Given the ring of integers Z, and an integer m>1, create the residue class ring Z/mZ.
Create the residue class containing k in the residue class ring R. Here k is allowed to be either an integer, or an element of the finite field F_p in the case R = Z/pZ, or an element of S = Z/nZ for a multiple or divisor n of m (with R = Z/mZ).
