Longitudinal evaluation of the cutaneous and rectal microbiota of German shepherd dogs with perianal fistulas undergoing therapy with ciclosporin and ketoconazole

open access: yesVeterinary Dermatology, Volume 35, Issue 4, Page 375-385, August 2024.
Background – Perianal fistulas are painful ulcers or sinus tracts that disproportionately affect German shepherd dogs and are proposed as a spontaneous animal model of fistulising Crohn's disease. Objectives – To characterise the rectal and cutaneous microbiota in German shepherd dogs with perianal fistulas and to investigate longitudinal shifts with ...

Unconditional correctness of recent quantum algorithms for factoring and computing discrete logarithms

open access: yesForum of Mathematics, Pi
In 1994, Shor introduced his famous quantum algorithm to factor integers and compute discrete logarithms in polynomial time. In 2023, Regev proposed a multidimensional version of Shor’s algorithm that requires far fewer quantum gates.

Some Lattice Attacks on DSA and ECDSA

open access: yes, 2010
In this paper, using the LLL reduction method and computing the integral points of two classes of conics, we develop attacks on DSA and ECDSA in case where the secret and the ephemeral key and their modular inverse are quite small or quite large.

An Efficient Algorithm for the Riemann Zeta Function

open access: yes, 1995
. A very simple class of algorithms for the computation of the Riemann-zeta function to arbitrary precision in arbitrary domains is proposed. These algorithms out perform the standard methods based on EulerMaclaurin summation, are easier to implement and

Computing Discrete Logarithms in Real Quadratic Congruence Function Fields of Large Genus

open access: yes, 1997
The discrete logarithm problem in various finite abelian groups is the basis for some well known public key cryptosystems. Recently, real quadratic congruence function fields were used to construct a public key distribution system.

On Computing Factors of Cyclotomic Polynomials

open access: yes, 1992
For odd square-free n ? 1 the cyclotomic polynomial \Phi n (x) satisfies the identity of Gauss 4\Phi n (x) = A 2 n \Gamma (\Gamma1) (n\Gamma1)=2 nB 2 n : A similar identity of Aurifeuille, Le Lasseur and Lucas is \Phi n ((\Gamma1) (n\Gamma1)=2 x)

Probabilistic Construction of Normal Basis.

open access: yes, 1998
Let Fq be the finite field with q elements. A normal basis polynomial f # Fq [x] of degree n is an irreducible polynomial, whose roots form a (normal) basis for the field extension Fq n : Fq . We show that a normal basis polynomial of degree n can be

On Some Computational Problems in Finite Abelian Groups

open access: yes
We present new algorithms for computing orders of elements, discrete logarithms, and structures of finite abelian groups. We estimate the computational complexity and storage requirements, and we explicitly determine the O-constants and\Omega\Gammad ...
