Dynamics of a Predator-Prey System with Beddington-DeAngelis Functional Response and Delays
Abstract and Applied Analysis, 2014 We consider a predator-prey system with Beddington-DeAngelis functional response and delays, in which not only the stage structure on prey but also the delay due to digestion is considered.

Dynamics of a host-pathogen model with constant mortality rate
Nonlinear Analysis, 2017 In this paper, we propose a discrete-time host-pathogen model and study its qualitative behavior. The model is for the spread of an infectious disease with constant mortality rate of hosts.

FEBS Letters, EarlyView.Ascidian Ciona larvae initially show strong clockwise tail twisting, which is largely corrected during development. However, a small residual twist remains. This study shows that organized helical myofibrils in tail muscles mechanically stabilize this residual asymmetry, preventing complete restoration of bilateral symmetry and revealing how embryos ...

Degradation mechanism of the von Willebrand factor A2 domain by nattokinase
FEBS Letters, EarlyView.Nattokinase, a natto‐derived protease, exhibits potent antithrombotic effects. This study demonstrates that nattokinase directly cleaves the von Willebrand factor (vWF) A2 domain in vitro. Unlike the native regulator ADAMTS13, nattokinase degrades folded vWF independently of shear stress.

Stability Analysis of a Population Model with Maturation Delay and Ricker Birth Function
Abstract and Applied Analysis, 2014 A single species population model is investigated, where the discrete maturation delay and the Ricker birth function are incorporated. The threshold determining the global stability of the trivial equilibrium and the existence of the positive equilibrium

Global stability of the positive equilibrium for a non-cooperative model of nuclear reactors
Electronic Journal of Qualitative Theory of Differential Equations, 2012 In this paper, we investigate the non-cooperative reaction-diffusion model of nuclear reactors subject to the homogeneous Neumann boundary condition. By establishing appropriate Lyapunov functions, we prove the global stability of the unique positive ...

Modulation of Homer1 EVH1 domain internal dynamics by putative autism‐associated mutations
FEBS Letters, EarlyView.The putative autism‐associated M65I and S97L variants of the EVH1 domain of the postsynaptic scaffold protein Homer1 do not exhibit substantial changes in their overall structure or partner binding. Both of them, but especially the M65I variant, show altered internal dynamics relative to the wild‐type domain on the μs‐ms timescale, indicated by the ...

Advances in Difference Equations, 2018 In this paper, a May cooperative system with strong and weak cooperative partners is proposed. First, by using differential inequality theory, we obtain the permanence and non-permanence of the system.

Journal of Biological Dynamics, 2021 We develop two discrete models to study how supplemental releases affect the Wolbachia spreading dynamics in cage mosquito populations. The first model focuses on the case when only infected males are released at each generation.

Equilibrium positions of acoustically levitated spheres [PDF]
The Journal of the Acoustical Society of America, 1980 Measurements of the equilibrium position of levitated, low-density spheres in air were made in a rectangular resonant system as a function of acoustic pressure. Vertical acoustic forces were generated by two opposing JBL compression drivers exciting the fundamental plane-wave mode at 1.2 kHz.
