Further results on permanents of Laplacian matrices of trees
Open MathematicsThe research on the permanents of graph matrices is one of the contemporary research topic in algebraic combinatorics. Brualdi and Goldwasser characterized the upper and lower bounds of permanents of Laplacian matrices of trees.

Jacobi matrices and boundary value problems in distance-regular graphs [PDF]
, 2012 In this work we analyze regular boundary value problems on a distance-regular graph associated with SchrÄodinger operators. These problems include the cases in which the boundary has two or one vertices.

Veterinary Dermatology, Volume 36, Issue 1, Page 74-82, February 2025.Background — Anal sac impaction is common in dogs and manual expression may be effective, yet recurrence remains a problem. To facilitate physiological emptying of the sacs, it is important to maintain a bulky stool consistency. Objectives — The study evaluated if supplementation with ProGlan, a complementary feed containing Bacillus velezensis C‐3102 ...

On an uncertainty principle for small index subgroups of finite fields
Open MathematicsIn this article, we continue the study of the nonvanishing minors property initiated by Garcia, Karaali, and Katz, for the compressed Fourier matrix attached to a subgroup HH of the multiplicative group of a finite field Fq{{\mathbb{F}}}_{q} and a ...

Recent trends on analytic properties of matrix orthonormal polynomials
, 2008 . In this paper we give an overview of recent results on analytic properties of matrix orthonormal polynomials. We focus our attention on the distribution of their zeros as well as on the asymptotic behavior of such polynomials under some restrictions ...

Linear maps preserving the Cullis’ determinant. III
Special MatricesThis paper is the third in the series of papers devoted to the explicit description of linear maps preserving the Cullis’ determinant of rectangular matrices of size n × k with entries belonging to an arbitrary ground field which is large enough. In this

Veterinary 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 ...

Infant Mental Health Journal: Infancy and Early Childhood, Volume 45, Issue 4, Page 397-410, July 2024.Abstract Whether and how remitted clinical depression in postpartum motherhood contributes to poor infant adaptive functioning is inconclusive. The present longitudinal study examines adaptive functioning in infants of mothers diagnosed as clinically depressed at 5 months but remitted at 15 and 24 months. Fifty‐five U. S.
