Dynamics of logistic systems driven by Levy noise under regime switching

Electronic Journal of Differential Equations, 2014
This article concerns the stochastic logistic models under regime switching with Levy noise. In the model, the color noise and Levy noise are taken into account at the same time. This model is new and more feasible and more accordance with the actual.

Asymptotic behavior of stochastic three-species predator-prey systems with white and Levy noise

Electronic Journal of Differential Equations, 2020
In this article, we propose a three-species prey-predator system with Holling II functional response and stochastic perturbations involving white noise and Levy noise.

A stochastic three-species food web model with Lévy jumps

Journal of Hebei University of Science and Technology, 2019
For a stochastic three-species food web model with double parameters perturbation and Lévy jumps, we give the existence and uniqueness of global positive solution,which is beneficial to further study its dynamic properties. Then, by constructing Lyapunov

On the origin and characteristics of noise-induced Lévy walks of E. coli. [PDF]

PLoS ONE, 2011
Lévy walks as a random search strategy have recently attracted a lot of attention, and have been described in many animal species. However, very little is known about one of the most important issues, namely how Lévy walks are generated by biological ...

Body weight in autism spectrum disorder: A systematic review and meta‐analysis

JCPP Advances, EarlyView.
Abstract Background Evidence on the relationship of autism spectrum disorder (ASD) to overweight/obesity and underweight is mixed. Moreover, it is unclear how this relationship changes with age. Methods We carried out a systematic review (SR) with meta‐analysis on the association between ASD and obesity, overweight and underweight across the life span.

Noncanonical Nucleotides in the Genome Around the Maternal‐Zygotic Transition

Journal of Experimental Zoology Part B: Molecular and Developmental Evolution, EarlyView.
In this paper, Kazzazi et al. provide a comprehensive review of the dynamics of nonconventional nucleotides in the genome during early developmental stages, hypothesizing a potential role for these nucleotides in the activation of the zygotic genome. ABSTRACT From the very moment of fertilization and throughout development, the cells of animal embryos ...

Addressing limitations in current measurement practices of trauma assessment in minoritized populations

Journal of Traumatic Stress, EarlyView.
Abstract Standardized trauma assessment frameworks often fail to account for the unique experiences and symptom presentations of minoritized populations, including Black, Indigenous, and people of color (BIPOC) and sexual and gender minority (SGM) individuals, leading to methodological inequity.

Existence and stability of mild solutions to parabolic stochastic partial differential equations driven by Lévy space-time noise

Electronic Journal of Qualitative Theory of Differential Equations, 2016
This paper is concerned with well-posedness and stability of parabolic stochastic partial differential equations. Firstly, we obtain some sufficient conditions ensuring the existence and uniqueness of mild solutions, and some $\mathcal{H}$-stability ...

Speech and Deep Brain Stimulation in Parkinson's Disease, Essential Tremor, and Dystonia: A Systematic Review and Meta‐analysis

Movement Disorders, EarlyView.
Abstract Deep brain stimulation (DBS) effectively treats motor symptoms in movement disorders but often compromises speech through incompletely defined mechanisms. We conducted a PROSPERO‐registered systematic review and meta‐analysis of publications through August 2024 (CRD42024527738).

Unveiling New Perspectives on the Hirota–Maccari System With Multiplicative White Noise

Mathematical Methods in the Applied Sciences, EarlyView.
ABSTRACT In this study, we delve into the stochastic Hirota–Maccari system, which is subjected to multiplicative noise according to the Itô sense. The stochastic Hirota–Maccari system is significant for its ability to accurately model how stochastic affects nonlinear wave propagation, providing valuable insights into complex systems like fluid dynamics
