Serum concentrations of IL‐31 in dogs with nonpruritic mast cell tumours or lymphoma
Background The aim of this study was to compare serum interleukin (IL)‐31 concentrations in dogs with lymphoma and mast cell tumours (MCT) without pruritus to those of healthy dogs. Hypothesis/Objectives To determine if IL‐31 plays a role in tumour pathogenesis and if IL‐31 could be a biological marker for disease progression.

Background– Pseudomonas aeruginosa (PA) may cause suppurative otitis externa with severe inflammation and ulceration in dogs. Multidrug resistance is commonly reported for this organism, creating a difficult therapeutic challenge. Objective– The aim of this study was to evaluate the in vitro antimicrobial activity of a gel containing 0.5 µg/mL of ...

Matrix measure and application to stability of matrices and interval dynamical systems
Using some properties of the matrix measure, we obtain a general condition for the stability of a convex hull of matrices that will be applied to study the stability of interval dynamical systems. Some classical results from stability theory are reproduced and extended.

The Dittert′s function on a set of nonnegative matrices
Let Kn denote the set of all n × n nonnegative matrices with entry sum n. For X ∈ Kn with row sum vector (r1, …, rn), column sum vector (c1, …, cn), Let ϕ(X)=∏iri+∏jcj−perX. Dittert′s conjecture asserts that ϕ(X) ≤ 2 − n!/nn for all X ∈ Kn with equality iff X = [1/n]n×n. This paper investigates some properties of a certain subclass of Kn related to the

Means of positive matrices [PDF]
Means of positive numbers are well-know but the theory of matrix means due to Kubo and Ando is less known. The lecture gives a short introduction to means, the emphasis is on matrices.

A sign pattern matrix is a matrix whose entries are from the set {+, −, 0}. The minimum rank of a sign pattern matrix A is the minimum of the ranks of the real matrices whose entries have signs equal to the corresponding entries of A.

Solving Euclidean Distance Matrix Completion Problems Via Semidefinite Programming
. Given a partial symmetric matrix A with only certain elements specified, the Euclidean distance matrix completion problem (EDMCP) is to find the unspecified elements of A that make A a Euclidean distance matrix (EDM).

ESTIMATING THE CONSUMPTION MATRIX FROM INEXACT DATA IN THE LEONTIEF MODEL
. The Leontief model, originally developed for describing an economic system in terms of mutually interrelated and structurally conditioned simultaneous flows of commodities and services, has important applications to wide ranging disciplines.
