Generalized matrix functions, determinant and permanent

open access: yesپژوهش‌های ریاضی, 2022
Introduction Since linear and multilinear algebra has many applications in different branches of sciences, the attention of many mathematicians has been attracted to it in recent decades. The determinant and the permanent are the most important functions

The enamel organic matrix: structure and function

open access: yesBrazilian Journal of Oral Sciences, 2015
Dental enamel is the most mineralized tissue in the vertebrate body and contains the largest known biologically formed hydroxyapatite crystals. Its formation occurs extracellularly through the collaboration of a proteic transient framework (the enamel ...

A Perspective Approach for Characterization of Lieb Concavity Theorem

open access: yesDemonstratio Mathematica, 2016
Lieb’s extension theorem holds for generalized p + q ∈ [0; 1] and Ando convexity theorem holds for q - r > 1. In this paper, we give a complete characterization for concavity or convexity of Lieb well known theorem in the case where p + q ≥ 1 or p+q ≤ 0.

THE GENERALIZED Q-BESSEL MATRIX FUNCTION OF TWO VARIABLES

open access: yesمجلّة جامعة عدن للعلوم الأساسيّة والتّطبيقيّة, 2020
The Bessel function is probably the best known special function, within pure and applied mathematics. In this paper, we introduce the generalized q-analogue Bessel matrix function of two variables.

MATRIX METALLOPROTEINASES AND THEIR FUNCTION IN MYOCARDIUM [PDF]

open access: yesBiomedical Papers, 2005
A significant number of myocardial diseases are accompanied by increased synthesis and degradation of the extracellular matrix (ECM) as well as by changed maturation and incorporation of ECM components. Important groups of enzymes responsible for both normal and pathological processes in ECM remodeling are matrix metaloproteinases (MMPs). These enzymes

Collagen VI microfibril structure reveals mechanism for molecular assembly and clustering of inherited pathogenic mutations

open access: yesNature Communications
Collagen VI links the cell surface to the extracellular matrix to provide mechanical strength to most mammalian tissues, and is linked to human diseases including muscular dystrophy, fibrosis, cardiovascular disease and osteoarthritis.

Exact Expressions for Kullback–Leibler Divergence for Multivariate and Matrix-Variate Distributions

open access: yesEntropy
The Kullback–Leibler divergence is a measure of the divergence between two probability distributions, often used in statistics and information theory. However, exact expressions for it are not known for multivariate or matrix-variate distributions apart ...
