Existence of almost periodic solution for neutral Nicholson blowflies model
Advances in Difference Equations, 2017 This paper is concerned with a class of neutral Nicholson blowflies models with leakage delays and linear harvesting terms. Under appropriate conditions, some criteria are established for the existence and global exponential stability of almost periodic ...

Admissible perturbations of exponential dichotomy roughness
Nonlinear Analysis: Theory, Methods & Applications, 1998 Consider the linear system \((*)\) \(dx/dt = A(t)x\) and the perturbed system \((**)\) \(dy/dt = (A(t)+ B(t))y\). It is assumed that \((*)\) has an exponential dichotomy. The authors derive conditions on the dichotomy constants and the norm \(| | B| | _\infty\) of the perturbation such that the exponential dichotomy of \((*)\) implies an ordinary or ...

Stabilizability of systems with exponential dichotomy [PDF]
Systems & Control Letters, 1987 Linear time-varying finite dimensional systems of the form \(\dot x(t)=A(t)x(t)+B(t)u(t)\), B, C are continuous real valued matrices, are considered. If \({\mathcal V}\) denotes a linear subspace of the function space of free motions \(\{\) x(\(\cdot)| \dot x=Ax\}\) the concept of controllability of the free trajectories into \({\mathcal V}\) is ...

Advanced Functional Materials, EarlyView.We have developed DEX/GM, an all‐natural, personalizable hybrid vaccine designed by coating dendritic cell‐derived exosomes (DEX) onto tumor cell membranes (GM) for sustained prophylaxis against glioblastoma (GBM). ABSTRACT Glioblastoma (GBM), one of the most aggressive and lethal brain tumors, remains incurable with a poor clinical prognosis.

Exponential Dichotomies for Elliptic PDE on Radial Domains [PDF]
, 2020 It was recently shown by the authors that a semilinear elliptic equation can be represented as an infinite-dimensional dynamical system in terms of boundary data on a shrinking one-parameter family of domains. The resulting system is ill-posed, in the sense that solutions do not typically exist forward or backward in time.

Advanced Functional Materials, EarlyView.A dual‐layer living hydrogel, ProΦGel, integrates bacteriophages and probiotics for synergistic wound infection therapy. The outer gelatin‐based matrix releases phages on demand in response to P. aeruginosa infections, while inner alginate beads sustain probiotic delivery.

On (h; k)-Dichotomy and (h; k)-Trichotomy of Noninvertible Evolution Operators in Banach Spaces
Annals of the West University of Timisoara: Mathematics and Computer Science, 2014 The paper considers some concepts of (h, k)-dichotomy and (h, k)-trichotomy for noninvertible evolution operators in Ba- nach spaces. A characterization of the (h, k)-trichotomy of an evolution operator in terms of (h, k)-dichotomy for two associated ...
