Implications of New Quantum Spin Perspective In Quantum Gravity
Consequences of new quantum spin perspective in quantum gravity are
far-reaching. Results of this novel perspective in loop quantum gravity, i.e.,
the modification of the equation of geometrical operators such as the area and
the volume operator are known. Using newly proposed formula from this
perspective, the magnitude of fundamental constants such as the reduced Planck
constant , the gravitational constant , the speed of light ,
the Boltzmann constant , the fine structure constant ,
can be validated. With the aid of this perspective, we find new formulas for
the fundamental Planckian quantities and the derived Planckian quantities. We
also propose novel formulas for the Planck star such as the size, the
curvature, the surface area and the size of black hole (for the Planck star)
without modifying its significance. The relation of the quantum spin with the
Planck temperature , the Planck mass
, the Planck length are also proposed using this novel perspectiveComment: 13 page

(E)-N′-{7-Methoxyspiro[chromeno[4,3-d]thiazole-4,1′-cyclohexan]-2-yl}-N,N-dimethylacetimidamide
In the chromenothiazole ring system of the title molecule, C20H25N3O2S, the pyran ring is in a half-chair conformation. The dihedral angle between the thiazole and benzene rings is 14.78 (6)°. The cyclohexane ring is in a chair conformation. The crystal structure is stabilized by weak intermolecular C—H⋯N and C—H⋯O hydrogen bonds
ATHENA detector proposal - a totally hermetic electron nucleus apparatus proposed for IP6 at the Electron-Ion Collider
ATHENA has been designed as a general purpose detector capable of delivering the full scientific scope of the Electron-Ion Collider. Careful technology choices provide fine tracking and momentum resolution, high performance electromagnetic and hadronic calorimetry, hadron identification over a wide kinematic range, and near-complete hermeticity.This article describes the detector design and its expected performance in the most relevant physics channels. It includes an evaluation of detector technology choices, the technical challenges to realizing the detector and the R&D required to meet those challenges
The United States COVID-19 Forecast Hub dataset
Academic researchers, government agencies, industry groups, and individuals have produced forecasts at an unprecedented scale during the COVID-19 pandemic. To leverage these forecasts, the United States Centers for Disease Control and Prevention (CDC) partnered with an academic research lab at the University of Massachusetts Amherst to create the US COVID-19 Forecast Hub. Launched in April 2020, the Forecast Hub is a dataset with point and probabilistic forecasts of incident cases, incident hospitalizations, incident deaths, and cumulative deaths due to COVID-19 at county, state, and national, levels in the United States. Included forecasts represent a variety of modeling approaches, data sources, and assumptions regarding the spread of COVID-19. The goal of this dataset is to establish a standardized and comparable set of short-term forecasts from modeling teams. These data can be used to develop ensemble models, communicate forecasts to the public, create visualizations, compare models, and inform policies regarding COVID-19 mitigation. These open-source data are available via download from GitHub, through an online API, and through R packages
