Veterinary Dermatology, Volume 37, Issue 2, Page 293-305, April 2026.Background: Canine atopic dermatitis (cAD) is a common, chronic skin condition characterised by epidermal barrier dysfunction, immune dysregulation and cutaneous dysbiosis. While “emollient plus” formulations are widely used in human atopic dermatitis, their role in cAD remains underexplored. Hypothesis/Objectives: To evaluate the clinical efficacy and

Exact Resolving Domination Numbers of Wheel‐Derived Graphs With an ILP Formulation
International Journal of Mathematics and Mathematical Sciences, Volume 2026, Issue 1, 2026.Let G = (V, E) be a simple, connected graph, and let d(a, g) denote the shortest distance between vertices a and g. An ordered subset R of V, with |R| = k and k∈N, is known as a resolving set if, for m ≠ c, ∃t ∈ R such that d(m, t) ≠ d(c, t), ∀m, c ∈ V–R. The distance code representation for b ∈ V − R w.r.t.

A branch-and-cut algorithm for the target visitation problem
EURO Journal on Computational Optimization, 2019 In this paper, we consider the target visitation problem (TVP) which arises in the context of disaster treatment. Mathematically speaking, the problem is concerned with finding a route to visit a set of targets starting from and returning to some base ...

Veterinary Dermatology, Volume 36, Issue 3, Page 302-313, June 2025.Background – Malassezia pachydermatis (MP) is implicated in severe dermatitis and otitis externa (OE) of companion animals and recently gained attention for its increasing resistance to azole compounds. For this reason, developing novel therapeutic strategies is of great interest. In a previous work, we used reference yeast isolates to evaluate several

Hair fragility (trichorrhexis nodosa) in alopecic Pomeranian dogs
Veterinary Dermatology, Volume 36, Issue 1, Page 64-73, February 2025.Background – Alopecia associated with hair cycle arrest (HCA, Alopecia X) is well‐recognised in Pomeranian dogs. The authors are unaware of reports of hair fragility in affected dogs. Hypothesis/Objectives – Following the observation of frequent hair shaft abnormalities in alopecic Pomeranians, we hypothesised that hair fragility events would be more ...

Improving strong branching by domain propagation
EURO Journal on Computational Optimization, 2014 One of the essential components of a branch-and-bound based mixed-integer linear programming (MIP) solver is the branching rule. Strong branching is a method used by many state-of-the-art branching rules to select the variable to branch on.

Integer decomposition for polyhedra defined by nearly totally unimodular matrices [PDF]
, 2005 . We call a matrix $A$ nearly totally unimodular if it can be obtained from a totally unimodular matrix $\tilde{A}$ by adding to each row of $\tilde{A}$ an integer multiple of some fixed row $a^{\transp}$ of $\tilde{A}$.
