Astronomers found a star that appeared to be orbiting nothing at all – but it’s actually the closest black hole ever at just 1000 light years away

Aerosol–radiation interaction (ARI) plays a significant role in the accumulation of fine particulate matter (PM2.5) by stabilizing the planetary boundary layer and thus deteriorating air quality during haze events. However, modification of photolysis by aerosol scattering or absorbing solar radiation (aerosol–photolysis interaction or API) alters the atmospheric oxidizing capacity, decreases...

Sub-Neptunes are common among the discovered exoplanets. However, lack of knowledge on the state of matter in H2O-rich setting at high pressures and temperatures (P−T) places important limitations on our understanding of this planet type. We have conducted experiments for reactions between SiO2 and H2O as archetypal materials for rock...

Transportation infrastructure owners manage an array of different asset types such as bridges, road pavements, earthworks and drainage. Currently, most organization management procedures are siloed by asset type; however, there are important interactions between these asset groups that need to be managed in a cross-asset way. Although these interactions are known, there is little or no quantification of these interactions. For the first time, this paper quantifies that 74% of Highways England's earthwork failures are a result of drainage-related problems, either the lack of drainage infrastructure or the poor performance of it. The analysis undertaken is an important first step not only in moving towards more connected asset management planning for earthworks and drainage, but to also provide guidance for other owners of earthwork infrastructure assets to improve their strategic asset management procedures.

This paper uses a 3D model for stability assessment of Zhujiabaobao waste dump with ground cracks. The study data were gathered via reconnaissance, geomorphological analysis and laboratory experiment. A 3D finite extended element method model that can consider cracks was then used to calculate the factor of safety (FOS) of the waste dump via the strength reduction technique. The simulation shows the dump to have an FOS of 1.22 and both the position and depth of penetration of cracks in the waste dump have a crucial impact on the stability of the slope. Because the study area is located in a seismically active area, simulation and analysis of the dynamic response of the waste dump under different magnitudes of seismic waves (peak acceleration is 0.05, 0.15, 0.25 and 0.45g) were performed via an explicit dynamic model. The simulation shows that high steps in the slope are particularly responsive to earthquakes. The approach used here for analysing stability under static and dynamic loads is useful for hazard prevention and mitigation.
