Serum concentrations of IL‐31 in dogs with nonpruritic mast cell tumours or lymphoma
Veterinary Dermatology, Volume 31, Issue 6, Page 466-e124, December 2020., 2020 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.

A stabilization theorem for dynamics of continuous opinions [PDF]
, 2005 A stabilization theorem for processes of opinion dynamics is presented. The theorem is applicable to a wide class of models of continuous opinion dynamics based on averaging (like the models of Hegselmann-Krause and Weisbuch-Deffuant).

Veterinary Dermatology, Volume 27, Issue 5, Page 391-e98, October 2016., 2016 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
International Journal of Mathematics and Mathematical Sciences, Volume 2003, Issue 2, Page 75-85, 2003., 2003 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
International Journal of Mathematics and Mathematical Sciences, Volume 13, Issue 4, Page 709-716, 1990., 1990 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

Interior points of the completely positive cone. [PDF]
, 2008 A matrix A is called completely positive if it can be decomposed as A = BB^T with an entrywise nonnegative matrix B. The set of all such matrices is a convex cone.

Lattice-like operations and isotone projection sets [PDF]
, 2013 By using some lattice-like operations which constitute extensions of ones introduced by M. S. Gowda, R. Sznajder and J. Tao for self-dual cones, a new perspective is gained on the subject of isotonicity of the metric projection onto the closed convex ...

Extremal copositive matrices with minimal zero supports of cardinality two
, 2017 Let $A \in {\cal C}^n$ be an extremal copositive matrix with unit diagonal. Then the minimal zeros of $A$ all have supports of cardinality two if and only if the elements of $A$ are all from the set $\{-1,0,1\}$.

Constructing matrix geometric means [PDF]
, 2010 In this paper, we analyze the process of "assembling" new matrix geometric means from existing ones, through function composition or limit processes.
