TL;DR: In this paper, the authors analyzed a coronavirus disease 2019 (COVID-19) outbreak involving three families in a restaurant in Guangzhou, China, assessed the possibility of airborne transmission, and characterized the associated environmental conditions.

TL;DR: Wang et al. as mentioned in this paper analyzed a COVID-19 outbreak in January 2020 in Hunan Province, China, involving an infected 24-year-old man, Mr. X, taking two subsequent buses, B1 and B2, in the same afternoon.

TL;DR: This study quantifies the influence of tree planting and aspect ratios on the thermal environment, which can provide meaningful references for urban tree plantings and produce high-quality validation data for numerical modeling.

TL;DR: In this article, an optimized ratio of relative changes (RRCs) was introduced to evaluate the flow regimes' similarity and showed that the fully Re-independent flow regimes in deep canyons have fewer vortices than the literature value with down-scale experiments and simulations.

TL;DR: In this paper, the effect of wind-driven and solar-heating conditions on urban air quality and thermal environment in typical reduced-canyon models with aspect ratios (AR) of 1.1, 2.4, 4 and 5.67 were investigated by CFD simulations using periodic boundary condition.
