Abstract Background The ongoing global COVID-19 pandemic is caused by SARS-CoV-2, a novel coronavirus first discovered at the end of 2019.It has led to more than 50 million confirmed cases and more than 1 million deaths across 219 countries as of 11 November 2020, according to WHO statistics.SARS-CoV-2, SARS-CoV, and MERS-CoV are similar.They are h
Motion planning for mobile robots considering occluded obstacles is a navigation challenge in dynamic Desk Fan environments.If an obstacle suddenly appears from the occluded area, a robot might collide with the obstacle.This is the occlusion problem.Therefore, this paper proposes a novel motion planner, Velocity Obstacle for Occlusion, VOO.The VOO
Abstract Background Betaine, an osmoprotective compatible solute, has been used to improve l-threonine production in engineered Escherichia coli l-threonine producer.Betaine supplementation upregulates the expression of zwf encoding glucose-6-phosphate dehydrogenase, leading to the increase of NADPH, which is beneficial for l-threonine production.I
ABSTRACT Nursery trees of stone fruits (Prunus spp.) are traditionally produced by union of two distinct genotypes - the rootstock and the scion - which, by grafting, form a composite plant that will be maintained throughout of all plant Collections life.In Brazil, the rootstocks are predominantly seed propagated and therefore usually results in he
Abstract Background Tsetse flies, the biological vectors of African trypanosomes, have established symbiotic associations with different bacteria.Their vector competence is suggested to be affected by bacterial endosymbionts.The current study provided the prevalence of three tsetse symbiotic bacteria and trypanosomes in Glossina species from Burkin
