Numerical dynamics of integrodifference equations

Numerische Mathematik, 2023
AbstractIntegrodifference equations are versatile models in theoretical ecology for the spatial dispersal of species evolving in non-overlapping generations. The dynamics of these infinite-dimensional discrete dynamical systems is often illustrated using computational simulations.

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.

Delay differential equation models for real-time dynamic substructuring [PDF]

, 2005
Real-time dynamic substructuring is a testing technique that models an entire system through the combination of an experimental test piece, representing part of the system, with a numerical model of the rest of the system.

Oscillatory and non-oscillatory solutions of dynamic equations with bounded coefficients

Electronic Journal of Differential Equations, 2018
We analyze second-order half-linear dynamic equations on time scales. We prove oscillation and non-oscillation criteria which are sharp in the sense that the considered equations remain uncovered only for one setting of their coefficients.

A Lyapunov Function For Logistic Equation On Time Scales

Sakarya Üniversitesi Fen Bilimleri Enstitüsü Dergisi, 2018
In this study we focus on the stability of dynamic logistic equation which is used in single species population dynamics. Here we have introduced a quadratic Lyapunov function for generalized dynamic logistic equation on time scales.

ABL kinase‐dependent phosphorylation of SH proteins promotes their direct interaction with CRK family SH2 domains

FEBS Letters, EarlyView.
CT10 regulator of kinase (CRK) and CRK‐Like (CRKL) are signaling adaptors driving cell adhesion, motility, differentiation, and proliferation. SH2‐domain containing (SH) proteins are enriched in YXXP motifs which when phosphorylated create preferred binding sites for CRK family SH2 domains.

Oscillations of First Order Delay Dynamic Equations

, 2006
Stavroulakis, Ioannis/0000-0002-4810-0540Consider the first order linear delay dynamic equation of the forms x(Delta)(t) + p(t)x(tau(t)) = 0. (E) New oscillation criteria are established which contain well-known criteria for delay differential and ...

Dynamics of the Schrödinger–Langevin equation [PDF]

Nonlinearity, 2021
Abstract We consider the nonlinear Schrödinger–Langevin equation for both signs of the logarithmic nonlinearity. We explicitly compute the dynamics of Gaussian solutions for large times, which is obtained through the study of a particular nonlinear differential equation of order 2.

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

FEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.
