Impact of N-Doping on MoSe Monolayer for PH, CN and HN Gas Sensing: A DFT Study.

In this research, the different characteristics of MoSe and N-doped MoSe monolayers were studied using density functional theory calculations. The negative cohesive energy (-5.216 eV for MoSe and -5.

COVID-19 responses restricted abilities and aspirations for mobility and migration: insights from diverse cities in four continents.

Research on the impacts of COVID-19 on mobility has focused primarily on the increased health vulnerabilities of involuntary migrant and displaced populations. But virtually all migration flows have been truncated and altered because of reduced economic and mobility opportunities of migrants. Here we use a well-established framework of migration decision-making, whereby individual decisions combine the aspiration and ability to migrate, to explain how public responses to the COVID-19 pandemic alter migration patterns among urban populations across the world.

Investigating the implications of COVID-19 outbreak on systems of care and outcomes of STEMI patients: A systematic review and meta-analysis.

Introduction: There has been a concern whether the decrease in ST-segment elevation myocardial infarction (STEMI) cases during the COVID-19 pandemic era is related to unsatisfactory performance of STEMI systems of care as well as worsening of the clinical outcomes in STEMI patients. Thus, our meta-analysis was conducted to evaluate this matter.

Methods: We compared the predetermined variables in this meta-analysis during the early and late pandemic.

Analysis of the CRISPR-Cas system in bacteriophages active on epidemic strains of Vibrio cholerae in Bangladesh.

CRISPR-Cas (clustered regularly interspersed short palindromic repeats-CRISPR-associated proteins) are microbial nuclease systems involved in defense against phages. Bacteria also resist phages by hosting phage-inducible chromosomal islands (PICI) which prevent phage reproduction. Vibrio cholerae which causes cholera epidemics, interacts with numerous phages in the environment and in cholera patients.
