Dynamical behavior of a general non-autonomous dynamical system
Applied General TopologyIn this work, we investigate dynamical notions such as minimality, almost periodicity, equicontinuity, transitivity, proximality and periodicity for a general non-autonomous dynamical system.

FEBS Open Bio, EarlyView.The MRP4 transporter exports several drugs and signaling molecules. Here, we identified key promoter elements regulating basal MRP4 expression. Using reporter assays, we defined a conserved region with essential Sp1 and contributory Ets sites, which controlled basal MRP4 expression.

Modeling Periodicity or Almost Periodicity in an Inhomogeneous Gamma Point Process [PDF]
, 2017 We propose a model for the analysis of an inhomogeneous Gamma processes (IGP) with a periodic or almost periodic baseline intensity function and shape parameter greater than zero. The IGP is a generalization of both the nonhomogeneous Poisson process and

Fixed-Time Multi-Almost-Periodicity in Switched Fuzzy Neural Networks with Multi-Controller Strategies [PDF]
This paper provides theoretical analysis of the fixed-time multi-almost-periodicity in switched fuzzy neural networks, employing multi-controller strategies and a state-dependent switching mechanism. Utilizing the Ascoli-Arzela theorem, the properties of

Discontinuous generalized double-almost-periodic functions on almost-complete-closed time scales
Boundary Value Problems, 2019 In this paper, we introduce the concept of almost-complete-closed time scales (ACCTS) that allows independent variables of functions to possess almost-periodicity under translations.

Acute caffeine treatment protects the developing retina from ischemia‐induced cell death
FEBS Open Bio, EarlyView.Caffeine reduces cell death in the developing retina under ischemia (OGD). This effect does not involve BDNF upregulation or antioxidant pathways (NRF2/VEGF). Neuroprotection occurs mainly through adenosine A2A receptor antagonism, decreasing glutamate release and excitotoxicity, highlighting caffeine's potential as an acute neuroprotective agent in ...

Bounded solutions of KdV: Uniqueness and the loss of almost periodicity [PDF]
International audienceWe address two pressing questions in the theory of the Korteweg–de Vries (KdV) equation. First, we show the uniqueness of solutions to KdV that are merely bounded, without any further decay, regularity, periodicity, or almost ...

Existence and Stability of Almost Periodic Solutions in Almost Periodic Systems
Publications of the Research Institute for Mathematical Sciences, 1976 where x$ are real, k is a positive integer and a^(f) are almost periodic functions of t. Under some conditions on ##(£), Theorem 1 shows that the trivial solution of the first approximation of system (1-1) is uniformly asymptotically stable in a subspace IT of R (see Definition 2) .

Almost periodicity of solutions for almost periodic evolution equations
Differential and Integral Equations, 2005 In this paper, we discuss almost periodicity of solutions for evolution equations in Banach space. We introduce the concept of difference-variation equation. For a special Hilbert space, we establish some results on almost periodicity of all solutions for evolution equations. In particular, we extend Haraux's result on $R^2$ to $R^n.$

Weakly almost periodic flows [PDF]
Transactions of the American Mathematical Society, 1989 The notion of the enveloping semigroup of a flow is applied to some situations in ergodic theory. In particular, weakly almost periodic functions on groups are studied and Moore’s ergodic theorem is proved.
