Multi-UAV Obstacle Avoidance and Formation Control in Unknown Environments
DronesTo address the issues of local minima, target unreachability, and significant formation disruption during obstacle avoidance in the conventional artificial potential field (APF), a control approach that integrates APF with optimal consensus control which

Accelerated synthesis of energetic precursor cage compounds using confined volume systems
Scientific Reports, 2021 Confined volume systems, such as microdroplets, Leidenfrost droplets, or thin films, can accelerate chemical reactions. Acceleration occurs due to the evaporation of solvent, the increase in reactant concentration, and the higher surface-to-volume ratios

Journal of Military Ethics, 2021 Neither non-lethal violence nor psychochemical weapons are new concepts. History provides examples of attempts to use these both to limit the scope of war and to turn mind-altering compounds into weapons. One of these substances has been marijuana. Although previous efforts to find its military applications failed, the idea persists - as indicated by a

American Journal of Community Psychology, EarlyView.Abstract In the U.S., crime and violence are concentrated in cities that have lost industry and population due to economic disinvestment and structurally racist policies. Researchers, practitioners, and policymakers have called for community‐level approaches that reduce violence in these cities by improving unsafe physical environments, increasing ...

Geoarchaeology, Volume 38, Issue 1, Page 57-75, January/February 2023., 2023 Abstract Geomorphology generally aims to describe and investigate the processes that lead to the formation of landscapes, while geochronology is needed to detect their timing and duration. Due to restrictions on exporting geological samples from Egypt, modern geoscientific studies in the Nile Delta lack the possibility of dating the investigated ...

Insect‐specific viruses used in biocontrol of mosquito‐borne diseases
Interdisciplinary Medicine, Volume 1, Issue 1, January 2023., 2023 Insect‐specific RNA viruses (ISRVs) are involved in a wide range of families including Flaviviridae, Bunyaviridae, Negeviruses, Togaviridae, Reoviridae, Mesoniviridae, and Rhabdoviridae, which cannot infect vertebrates, including humans. However, ISRVs can infect and replicate in mosquitoes, interfering with the replication of mosquito‐borne viruses ...
