We present a catalogue of 362 million stellar parameters, distances, and extinctions derived from Gaia’s Early Data Release (EDR3) cross-matched with the photometric catalogues of Pan-STARRS1, SkyMapper, 2MASS, and AllWISE. The higher precision of the Gaia EDR3 data, combined with the broad wavelength coverage of the additional photometric surveys and the new stellar-density priors of the StarHorse code, allows us to substantially improve the accuracy and precision over previous photo-astrometric stellar-parameter estimates. At magnitude G = 14 (17), our typical precisions amount to 3% (15%) in distance, 0.13 mag (0.15 mag) in V-band extinction, and 140 K (180 K) in effective temperature. Our results are validated by comparisons with open clusters, as well as with asteroseismic and spectroscopic measurements, indicating systematic errors smaller than the nominal uncertainties for the vast majority of objects. We also provide distance- and extinction-corrected colour-magnitude diagrams, extinction maps, and extensive stellar density maps that reveal detailed substructures in the Milky Way and beyond. The new density maps now probe a much greater volume, extending to regions beyond the Galactic bar and to Local Group galaxies, with a larger total number density. We publish our results through an ADQL query interface (gaia.aip.de) as well as via tables containing approximations of the full posterior distributions. Our multi-wavelength approach and the deep magnitude limit render our results useful also beyond the next Gaia release, DR3.

Due to the novelty of coronavirus disease 2019 and the lack of measurable data, no enough research studies have been conducted to provide guidelines for responding to the coronavirus pandemic. This paper addresses this critical knowledge gap through a methodology comprising two main steps. The first step involved reviewing the updated industry best practices developed by various organizations and government entities. The second step involved investigating the impacts of the coronavirus based on the available resources and expert opinions, which also were used to develop a synopsis of emerging research topics. This paper provided various beneficial outcomes and findings. First, the paper presents a concise and integrated resource of COVID-19-related best practices for the construction industry. Second, the paper determined that the pandemic is perceived to have short-and long-term impacts-including negative and positive consequences-on four main facets: (1) workforce-related issues; (2) project and workplace considerations; (3) procurement and supply chain implications; and (4) contractual, legal, and insurance aspects. Third, the paper provides future research streams and directions that could be examined by future studies to help in the transition toward the new normal. Ultimately, this paper adds to the body of knowledge by offering practitioners and researchers guidelines for responding to the COVID-19 pandemic in the construction sector.
