Chemotactic predator-prey dynamics

, 2010
A discrete chemotactic predator-prey model is proposed in which the prey secrets a diffusing chemical which is sensed by the predator and vice versa. Two dynamical states corresponding to catching and escaping are identified and it is shown that steady ...

Threat-sensitive anti-predator defence in precocial wader, the northern lapwing Vanellus vanellus [PDF]

, 2016
Birds exhibit various forms of anti-predator behaviours to avoid reproductive failure, with mobbing—observation, approach and usually harassment of a predator—being one of the most commonly observed. Here, we investigate patterns of temporal variation in

OCTOID: A Soft Robotic System Featuring Programmable Shape Morphing and Dynamic Structural Coloration

Advanced Functional Materials, EarlyView.
Inspired by octopuses, actuating legs based on soft materials are fabricated with programmed chiroptical properties and mechanical behaviors to achieve dynamic color modulation and reversible shape morphing, and these legs are developed into a modular OCTOID system.

The complete mitogenome sequence of the agricultural pest, clover root weevil: the key to its own demise?

Mitochondrial DNA. Part B. Resources, 2019
We report the complete mitogenome of Sitona obsoletus, an agricultural pest in New Zealand and some European countries. Like other Sitona mitogenomes, the 6 tRNA gene box is ordered RNSAEF, supporting the hypothesis that this signature is common to, and ...

Switching model with two habitats and a predator involving group defence

, 1998
Switching model with one predator and two prey species is considered. The prey species have the ability of group defence. Therefore, the predator will be attracted towards that habitat where prey are less in number.

Dual‐Interface Engineering of the Source Electrode to Overcome the Intrinsic Injection‐Leakage Trade‐Off in Organic Schottky Barrier Transistors

Advanced Functional Materials, EarlyView.
A charge injection layer is introduced via RIE to decouple the dual functions of the source electrode: lowering contact resistance through doping to enhance charge injection, while SAM modification on the top surface minimizes leakage current. This strategy enables OSBTs to achieve a high on/off ratio with improved stability and performance.

Modifying M‐44s to reduce risk of activation by swift fox

Wildlife Society Bulletin, 2016
M‐44s are spring‐powered sodium cyanide ejectors commonly used in the United States to manage livestock depredation by coyotes (Canis latrans). While highly selective for canids, improvements could reduce risk to nontarget canids, especially State ...

Toward Smart Moving Target Defense for Linux Container Resiliency

, 2016
This paper presents ESCAPE, an informed moving target defense mechanism for cloud containers. ESCAPE models the interaction between attackers and their target containers as a "predator searching for a prey" search game. Live migration of Linux-containers

Intraguild predation among aphidophagous predators [PDF]

European Journal of Entomology, 2005
Since the publication of papers by Polis et al. (1989, 1992), intraguild predation (IGP) has been considered in numerous systems and a growing number of papers have been published, demonstrating the ubiquity and the importance of this interaction. It appears that aphidophagous guilds constitute especially favourable systems for IGP.

Laser‐Microscribed Glass Enables Surface‐Microfluidics‐Facilitated, Affordable, Rapid Cancer Diagnosis

Advanced Functional Materials, EarlyView.
A transparent, laser‐microscribed glass platform enables cancer diagnosis within 1 h—much faster than histology, which takes days, and free from the chemical or contrast risks of MRI or CT scans. The antibody‐functionalized rough glass surface captures viable cancer cells directly from suspension, allowing instant optical readout and offering a rapid ...
