The extinction profiles in gamma-ray burst (GRB) afterglow spectral energy distributions (SEDs) are usually described by the small magellanic cloud (SMC)-type extinction curve. In different empirical extinction laws, the...
The Effects of Spatial Planning, Well-Being, and Behavioural Changes During and After the COVID-19 Pandemic
COVID-19 poses a massive challenge to urban public-health emergency and governance systems. Urban planners and policymakers engaged in spatial planning and management should carefully consider how a “people-oriented”...

Mechanisms of Choice in X-Chromosome Inactivation.
Early in development, placental and marsupial mammals harbouring at least two X chromosomes per nucleus are faced with a choice that affects the rest of their lives: which of those X chromosomes to transcriptionally inactivate....
Applications of nanoparticles in topical drug delivery and in cosmetics
The delivery of drugs and active agents to the skin by formulations containing nanoparticles is a topic of considerable current interest. A number of studies have shown important advantages of these nanostructure-based delivery...
