Ultra diffuse galaxies in the Hydra I cluster from the LEWIS Project: Phase-Space distribution and globular cluster richness [PDF]
arXiv, 2023 Although ultra diffuse galaxies (UDGs) are found in large numbers in clusters of galaxies, the role of the cluster environment in shaping their low surface brightness and large sizes is still uncertain. Here we examine a sample of UDGs in the Hydra I cluster (D = 51 Mpc) with new radial velocities obtained as part of the LEWIS (Looking into the ...

Hydrogen Drives Part of the Reverse Krebs Cycle under Metal or Meteorite Catalysis
Angewandte Chemie International Edition, Volume 61, Issue 51, December 19, 2022., 2022 Hydrogen is a geological reducing agent that powers the metabolisms of modern organisms and potentially also powered the metabolism of the last universal common ancestor to all extant life. It is shown that catalytic amounts of transition metals or small amounts of powdered meteorites allow hydrogen to drive a key sequence of the reverse Krebs cycle ...

Advanced Materials, Volume 37, Issue 13, April 2, 2025.Metal‐covalent organic frameworks (MCOFs) are novel porous materials that exhibit the advantages of covalent and metal‐organic frameworks. However, it is extremely difficult to resolve their atomic structure and better understand their structure‐properties relation. This work utilizes a synergistic combination of advanced microscopy, spectroscopic, and

Top quark mass measurement in radiative events at electron-positron colliders [PDF]
, 2019 In this letter, we evaluate potential of linear $e^+e^-$ colliders to measure the top quark mass in radiative events and in a suitable short-distance scheme. We present a calculation of the differential cross section for production of a top quark pair in association with an energetic photon from initial state radiation, as a function of the invariant ...

A Data-Driven Approach for Rathke’s Cleft Cysts Management
DiagnosticsBackground: Rathke’s cleft cysts (RCCs) are non-neoplastic and rare sellar lesions derived from remnants of Rathke’s pouch. While asymptomatic RCCs often require only conservative management, symptomatic cases may necessitate surgical intervention.
