Tidal disruption events (TDEs) offer a unique way to study dormant black holes.While the number of gewehr 91 observed TDEs has grown thanks to the emergence of wide-field surveys in the past few decades, questions regarding the nature of the observed optical, UV, and X-ray emission remain.We present a uniformly selected sample of 30 spectroscopical
Interactions between Weeds, Pathogen Symptoms and Winter Rapeseed Stand Structure
Rapeseed, weeds, and pathogens interact with each other.However, these interactions are not well understood.The aim of our work was to describe the relationships between weed vegetation and pathogen manifestations in rapeseed stands.Results from the four seasons show that different rapeseed stand structures produce different weed and pathogen respo
Urban Atmospheric Boundary-Layer Structure in Complex Topography: An Empirical 3D Case Study for Stuttgart, Germany
Investigation of the atmospheric boundary-layer structure in urban areas can be challenged by landscape complexity and the heterogenous conditions this instills.Stuttgart, Germany, is a city situated in a bowl-shaped basin and troubled by the accumulation of pollutants during weak-wind conditions.The center of Stuttgart is surrounded by steep slope
Estimating ventilation rates in rooms with varying occupancy levels: Relevance for reducing transmission risk of airborne pathogens.
BackgroundIn light of the role that airborne transmission plays in the spread of SARS-CoV-2, as well as the ongoing high global mortality from well-known airborne diseases such as tuberculosis and measles, there is an urgent need for practical ways of identifying congregate spaces vista 5 vl5 where low ventilation levels contribute to high transmis
