Permanence, stability, and coexistence of a diffusive predator–prey model with modified Leslie–Gower and B–D functional response

This paper investigates a diffusive predator–prey system with modified Leslie–Gower and B–D (Beddington–DeAngelis) schemes. Firstly, we discuss stability analysis of the equilibrium for a corresponding ODE system. Secondly, we prove that the system is permanent by the comparison argument of parabolic equations. Thirdly, sufficient conditions for the global asymptotic stability of...

Passive Cushiony Biomechanics of Head Protection in Falling Geckos

Gekko geckos are capable to crawl on the steep even on upside-down surfaces. Such movement, especially at great altitude, puts them at high risks of incidentally dropping down and inevitable body or head impactions, though they may trigger air-righting reaction (ARR) to attenuate the landing shocks. However, the air-righting ability (ARA) in Gekko geckos is not fully developed...

Dynamical Analysis of a Class of Prey-Predator Model with Beddington-DeAngelis Functional Response, Stochastic Perturbation, and Impulsive Toxicant Input

A stochastic prey-predator system in a polluted environment with Beddington-DeAngelis functional response is proposed and analyzed. Firstly, for the system with white noise perturbation, by analyzing the limit system, the existence of boundary periodic solutions and positive periodic solutions is proved and the sufficient conditions for the existence of boundary periodic...

Statin Use and the Risk of Parkinson's Disease: An Updated Meta-Analysis

Introduction In response to the ongoing debate over the relationship between the use of statins and the risk of Parkinson's disease (PD), we performed a systematic review and meta-analysis of observational studies to examine their association. Methods We conducted a review of the literature using electronic databases supplemented by a manual search to identify potentially...

Does local ambient temperature impact children’s blood pressure? A Chinese National Survey

Background Several studies demonstrated a short-term association between ambient temperature and blood pressure. However, few studies have assessed the long-term effect of ambient temperature on children’s blood pressure. The present study aimed to investigate the association between long-term exposure to local ambient temperature and children’s blood pressure in China. Methods...

Angiotensin-converting enzyme insertion/deletion gene polymorphisms associated with risk of atrial fibrillation: A meta-analysis of 23 case-control studies

Aims: The renin-angiotensin-aldosterone system is important to the development of atrial fibrillation (AF). A lot of research has focused on the relationship between angiotensin-converting enzyme (ACE) insertion (I) /deletion (D) gene polymorphisms and AF, with inconsistent results. A meta-analysis was carried out to find the correlation between ACE I/D gene polymorphisms and AF.

Analytical Methods for Temperature Field and Temperature Stress of Column Pier under Solar Radiation

Based on the previous research work, a new idea is proposed for analyzing the impact of solar radiation on the substructure of bridges. Investigation is conducted in the thermodynamic phenomena and temperature stress of a dual-column pier. Research is led to the thermal conductivity of concrete structure and the values of the environmental parameters under solar radiation. An...

Use of opposite frictional forces by animals to increase their attachment reliability during movement

Many animals have the natural ability to move on various surfaces, such as those having different roughness and slope substrates, or even vertical walls and ceilings. Legged animals primarily attach to surfaces using claws, soft and hairy pads, or combinations of them. Recent studies have indicated that the frictional forces generated by these structures not only control the...
