Periodic measures are the time-periodic counterpart to invariant measures for dynamical systems and can be used to characterise the long-term periodic behaviour of stochastic systems. This paper gives sufficient conditions for the existence, uniquene

In this article, we establish the probability foundation of the periodic measure approach in analysing periodicity of a dataset. It is based on recent work of random periodic processes. While random periodic paths provide a pathwise model for time se

Hypericin has shown promising potential for the prevention and treatment of cancer. Here we report facile strategy for the separation and purification of natural products from the extracts by demonstrating hypericin isolation from Hypericum perforatu

Ergodicity of random dynamical systems with a periodic measure is obtained on a Polish space. In the Markovian case, the idea of Poincar\'e sections is introduced. It is proved that if the periodic measure is PS-ergodic, then it is ergodic. Moreover,

Hypericin is considered to be the most biologically active substance in the crude extract of Hypericum perforatum L. (also known as St. John’s wort) and has a wide range of pharmacological effects. In this study, a high resolution high performance

Glucosinolates can be hydrolyzed by the enzyme commonly known as myrosinase (E.C. 3.2.1.147) to a variety of biological compounds. Myrosinase (MYR) has been immobilized through the flexible spacers of different length on cross-linked chitosan resin (

Saint Raymond asked whether continuously differentiable maps with isolated critical points are necessarily open in infinite dimensional (Hilbert) spaces. We answer this question negatively by constructing counterexamples in various settings including

In this paper, we consider numerical approximation to periodic measure of a time periodic stochastic differential equations (SDEs) under weakly dissipative condition. For this we first study the existence of the periodic measure ρ t and the large ti

In this paper, we study the existence, uniqueness and the probabilistic representation of the weak solutions of quasi-linear parabolic and elliptic partial differential equations (PDEs) in the Sobolev space H ρ 1 ( R d ) . For this, we study first t
