Contact tracing is a non-pharmaceutical intervention (NPI) widely used in the control of the
COVID-19 pandemic. Its effectiveness may depend on a number of factors including the …

This study systematically reviews applications of three simulation approaches, that is,
system dynamics model (SDM), agent‐based model (ABM) and discrete event simulation …

Two years after the emergence of SARS-CoV-2, there is still a need for better ways to assess
the risk of transmission in congregate spaces. We deployed active air samplers to monitor …

The instability toward a magnetic skyrmion crystal in centrosymmetric trilayer magnets is
investigated based on a spin model with layer-dependent Dzayloshinskii-Moriya interaction …

The new coronavirus, SARS-CoV-2, caused the COVID-19 pandemic, characterized by its
high rate of contamination, propagation capacity, and lethality rate. In this work, we …

Background The continuous mutation of severe acute respiratory syndrome coronavirus 2
has made the coronavirus disease 2019 (COVID-19) pandemic complicated to predict and …

Contagious respiratory diseases, such as COVID-19, depend on sufficiently prolonged
exposures for the successful transmission of the underlying pathogen. It is important that …

“The current study measures the influence of multitasking behavior and self-efficacy for self-
regulated learning (SESRL) on perceptions of academic performance and views in …

We identify a mechanism to convert skyrmions and antiskyrmions into their antiferromagnetic
(AFM) counterparts via interface engineering. The key idea is to combine properties of an …

Magnetic skyrmions are spin topological textures of potential interest in spintronics-related
data storage and processing devices. Here, we show the emergence of unconventional …
