A neuro‐behavioural model of neophobia

open access: yesBiological Reviews, EarlyView.
ABSTRACT Fear can be defined as the internal neurological state that releases a repertoire of behaviours an animal performs to reduce the effect of an aversive factor. Neophobia, the fear of novelty, is a fundamental behavioural trait observed across a wide range of species from arthropods to humans.

Neuroactive venom compounds obtained from Phlogiellus bundokalbo as potential leads for neurodegenerative diseases: insights on their acetylcholinesterase and beta-secretase inhibitory activities in vitro

open access: yesJournal of Venomous Animals and Toxins including Tropical Diseases, 2021
Background Spider venom is a rich cocktail of neuroactive compounds designed to prey capture and defense against predators that act on neuronal membrane proteins, in particular, acetylcholinesterases (AChE) that regulate synaptic transmission through ...

Data‐Based Detection of Antagonistic Agents in a Robot Swarm Solving a Dynamic Coverage Task

open access: yesInternational Journal of Mechanical System Dynamics, EarlyView.
ABSTRACT Robot swarms can be deployed as moving surveillance systems, for instance, as mobile anti‐poaching systems for monitoring wildlife and detecting poaching activities. Since poachers have an interest in evading detection, robots are at risk of being hijacked and manipulated to behave antagonistically, for example, to prevent the correct ...

Lecanicillium aphanocladii: a biocontrol agent against insect pests and phytopathogens

open access: yesPest Management Science, EarlyView.
Recent research findings on the biocontrol potential of Lecanicillium aphanocladii fungus against insect‐pests and plant diseases were highlighted. This review indicates that several L. aphanocladii strains show great potential to be developed as multipurpose biocontrol agents active against several insect‐pests, plant diseases and plant parasitic ...

Diversification of a single ancestral gene into a successful toxin superfamily in highly venomous Australian funnel-web spiders [PDF]

open access: yes, 2014
Background: Spiders have evolved pharmacologically complex venoms that serve to rapidly subdue prey and deter predators. The major toxic factors in most spider venoms are small, disulfide-rich peptides.

Peptide Toxins in Solitary Wasp Venoms

open access: yesToxins, 2016
Solitary wasps paralyze insects or spiders with stinging venom and feed the paralyzed preys to their larva. Accordingly, the venoms should contain a variety of constituents acting on nervous systems.

Why Autonomous Vehicles Are Not Ready Yet: A Multi‐Disciplinary Review of Problems, Attempted Solutions, and Future Directions

open access: yesJournal of Field Robotics, EarlyView.
ABSTRACT Personal autonomous vehicles can sense their surrounding environment, plan their route, and drive with little or no involvement of human drivers. Despite the latest technological advancements and the hopeful announcements made by leading entrepreneurs, to date no personal vehicle is approved for road circulation in a “fully” or “semi ...
