Selective Predation of a Stalking Predator on Ungulate Prey

PLOS ONE, 2016
Prey selection is a key factor shaping animal populations and evolutionary dynamics. An optimal forager should target prey that offers the highest benefits in terms of energy content at the lowest costs. Predators are therefore expected to select for prey of optimal size. Stalking predators do not pursue their prey long, which may lead to a more random

Balancing Exploration and Exploitation Through a Sequential Hybrid of Roach Infestation and Mayfly Algorithms for Constrained Engineering Design Optimization

AI &Innovation, EarlyView.
ABSTRACT Maintaining an effective balance between exploration and exploitation is essential during optimization processes, from mathematical functions to more complex problems such as constrained engineering design optimization, particularly when addressing highly nonlinear issues with numerous local optima and strict feasibility requirements.

Shearing Tooth Morphology May Allow Sharks to Access Higher Trophic Levels at Smaller Sizes

Ecology and Evolution
The availability of prey in an environment does not ensure that a predator will consume it: prey must also be detected, captured, and successfully handled. The morphology of the predator and prey imposes limitations on prey selection due to biomechanical

Ecology of predator-prey and predator-predator interactions in a multi-predator context

Ecologie des interactions prédateurs-proies et prédateurs prédateurs dans un contexte multiprédateur La coexistence d’espèces de grands carnivores n’est pas rare, l’objectif de cette thèse est de comprendre comment cela affecte les interactions proie-prédateurs.

Optimizing Electrode Design for Functional Activation of Human Pluripotent Stem Cell‐Derived Cardiomyocytes

Advanced NanoBiomed Research, EarlyView.
Electrical stimulation of human pluripotent stem cell‐derived cardiomyocytes is systematically investigated as a function of electrode material and configuration. Stimulation efficiency is found to be governed predominantly by electrode geometry, with increased electrode area and proximity to cells enabling more effective pacing.

Chronic exposure to a predator or its scent does not inhibit male–male competition in male mice lacking brain serotonin

Frontiers in Behavioral Neuroscience, 2014
Although it is well-known that defective signaling of the 5-HT system in the brain and stressful stimuli can cause psychological disorders, their combined effects on male–male aggression and sexual attractiveness remain unknown.

Stability analysis in generalist predator-prey dynamics with predator harvesting [PDF]

This paper seeks to explore the stability assessment of a generalist predator-prey system with predator harvesting. The study presents a model examining the dynamics between primary prey and predator, considering the existence of a generalist predator ...

Diffusion‐Governed Growth Mechanisms of Epitaxial GaAs Islands on CMOS‐Compatible Si(001) Nanotip Arrays

Advanced Physics Research, EarlyView.
The mechanism and kinetics of selective GaAs growth on Si nanotip wafers via nanoheteroepitaxy were investigated as a function of pitch (center‐to‐center nanotip spacing). The pitch dependence reveals distinct surface‐diffusion‐controlled regimes, demonstrating that lateral Ga adatom transport on the SiO2 mask governs material redistribution and ...
