Microbiome−host proteostasis crosstalk—An emerging perspective on mechanisms and interventions toward healthy longevity

FEBS Letters, EarlyView.
Proteostasis and the gut microbiota play a key role in shaping host physiology. Microbiota‐derived metabolites, vitamins, and RNA modulate host proteostasis. Findings from model systems, including C. elegans, indicate microbes can either stabilize or disrupt host proteostasis.

Numerical Solution of Duffing Equation by Using an Improved Taylor Matrix Method

Journal of Applied Mathematics, 2013
We have suggested a numerical approach, which is based on an improved Taylor matrix method, for solving Duffing differential equations. The method is based on the approximation by the truncated Taylor series about center zero.

Some Properties of the Solution to a System of Quaternion Matrix Equations

Axioms, 2022
This paper investigates the properties of the ϕ-skew-Hermitian solution to the system of quaternion matrix equations involving ϕ-skew-Hermicity with four unknowns AiXi(Ai)ϕ+BiXi+1(Bi)ϕ=Ci,(i=1,2,3),A4X4(A4)ϕ=C4. We present the general ϕ-skew-Hermitian solution to this system.

Modelling stem cell differentiation related processes—A practical overview for biologists

FEBS Letters, EarlyView.
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Alternative methods for representing the inverse of linear programming basis matrices [PDF]

, 1988
Methods for representing the inverse of Linear Programming (LP) basis matrices are closely related to techniques for solving a system of sparse unsymmetric linear equations by direct methods.

Solving the solution of Goursat problem using the Riemann method for a system of fourth order hyperbolic differential equations

Вестник Самарского университета: Естественнонаучная серия
Boundary value problems for certain systems of hyperbolic-type differential equations can be effectively solved using the Riemann method. In this paper, we consider an approach for constructing the Riemann matrix for a system of fourth order hyperbolic ...

On a boundary value problem for a system of hyperbolic equations with the wave operator and a singular coefficient of lower derivatives

Vestnik Samarskogo Gosudarstvennogo Tehničeskogo Universiteta. Seriâ: Fiziko-Matematičeskie Nauki, 2013
The boundary value problem with data given on the parallel characteristics for the system of hyperbolic equations with the wave operator and the singular matrix coefficient at the lower derivative is considered in the characteristic square.

Tumour–host interactions in Drosophila: mechanisms in the tumour micro‐ and macroenvironment

Molecular Oncology, EarlyView.
This review examines how tumour–host crosstalk takes place at multiple levels of biological organisation, from local cell competition and immune crosstalk to organism‐wide metabolic and physiological collapse. Here, we integrate findings from Drosophila melanogaster studies that reveal conserved mechanisms through which tumours hijack host systems to ...

Matrix Algebra and System of Linear Equations [PDF]

, 2020
U ovome ćemo se radu baviti svojstvima matrica i sustavom linearnih jednadžbi. Najprije ćemo definirati što je matrica, kako ih zovemo prema njihovom obliku, te koje sve operacije možemo raditi s njima.
