Effects of landscape fragmentation on floodplain fishes as revealed by species–habitat networks
Conservation Biology, Volume 40, Issue 1, February 2026.Abstract How species interact with habitat patches is influenced primarily by habitat configuration (e.g., connectivity) and species’ functional traits. As levels of fragmentation increase, identifying the intricate connections between these components is crucial for biodiversity conservation.

Average Continuous Control of Piecewise Deterministic Markov Processes
, 2008 This paper deals with the long run average continuous control problem of piecewise deterministic Markov processes (PDMP's) taking values in a general Borel space and with compact action space depending on the state variable.

Efficient auxiliary-mode approach for time-dependent nanoelectronics
New Journal of Physics, 2016 A new scheme for numerically solving the equations arising in the time-dependent non-equilibrium Green's function formalism is developed. It is based on an auxiliary-mode expansion of the self-energies which convert the complicated set of integro ...

Hopf bifurcation of integro-differential equations
Electronic Journal of Qualitative Theory of Differential Equations, 2000 A method reducing integro-differential equations (IDEs) to system of ordinary ones is proposed. On this base stability and bifurcation phenomena in critical cases are studied.

Asymptotic solutions of forced nonlinear second order differential equations and their extensions
, 2007 Using a modified version of Schauder's fixed point theorem, measures of non-compactness and classical techniques, we provide new general results on the asymptotic behavior and the non-oscillation of second order scalar nonlinear differential equations on

Linear Analysis of an Integro-Differential Delay Equation Model
International Journal of Differential Equations, 2018 This paper presents a computational study of the stability of the steady state solutions of a biological model with negative feedback and time delay. The motivation behind the construction of our system comes from biological gene networks and the model ...

Periodic solutions of integro-differential equations in Banach space having Fourier type
, 2017 The aim of this work is to study the existence of a periodic solutions of integro-differential equations d dt [x(t)-- L(x t)] = A[x(t)-- L(x t)]+ G(x t)+ t --$\infty$ a(t-- s)x(s)ds+ f (t), (0 $\le$ t $\le$ 2$\pi$) with the periodic condition x(0) = x(2$\
