This study Shields presents features of green roofs in urban areas with a particular emphasis on the filtration of air pollutants, heavy metals removal, reduction of rainwater runoff from roof surfaces and thermal insulation.To carry out field studies on the influence of green roofs on the environment in urban areas, two green roof models on a labo
This article presents an efficient and effective design approach of the phase distribution calculation across metasurface for significant radar cross section (RCS) reduction of a circular polarization (CP) and liner polarization (LP) radar waves.The RCS reduction using the proposed design approach is achieved by imposing a novel cusp phase mask (wh
In this paper, we present an incentivized experiment to Fire Screen investigate the degree of loss aversion when people make decisions for their current selves and future selves under risk.We find that when participants make decisions for their future selves, they are less loss averse compared to when they make decisions for their current selves.Th
Abstract Background Since the development of the coronavirus disease 2019 vaccine, there have been many reports of its adverse effects.While respiratory symptoms are common, many other symptoms in various organs have been reported.Herein, we report a case of optic disc and retinal hemorrhage that developed immediately after coronavirus disease 2019
Abstract Lanthanide-doped nanocrystals are promising for photon frequency upconversion with substantial spectrum tunability.However, the utilization of the upconversion process has been constrained by low luminescence efficiency, which may further attenuate at elevated temperatures due to thermal quenching.Herein, we report a versatile strategy to
