Description of the skull, braincase, and dentition of Moschognathus whaitsi (Dinocephalia, Tapinocephalia), and its palaeobiological and behavioral implications

open access: yesThe Anatomical Record, EarlyView.
Abstract A subadult Moschognathus whaitsi from the Eastern Cape Province, South Africa, was scanned using synchrotron radiation X‐ray computed tomography (SRXCT). Its subadult state allowed the cranial bones and teeth to be identified and individually reconstructed in 3D.

Stellar Flares: Observations and Theory [PDF]

open access: yesInternational Astronomical Union Colloquium, 1989
AbstractPhotometric and spectroscopic observations of a very large flare on AD Leo are presented. A self consistent model of a flare corona, transition region and chromosphere is developed; in particular the chromospheric temperature distributions resulting from X-ray and EUV irradiation by coronae of various temperatures are determined.

New partial skeleton of Homo habilis from the upper Burgi Member, Koobi Fora Formation, Ileret, Kenya

open access: yesThe Anatomical Record, EarlyView.
Abstract KNM‐ER 64061 is a partial skeleton from the upper Burgi Member of the Koobi Fora Formation (2.02–2.06 Ma) associated taphonomically and geochemically with a nearly complete mandibular dentition (KNM‐ER 64060) attributed to Homo habilis.

Starspot Distribution and Flare Events in Two Young Low-mass Stars Using TESS Data

open access: yesThe Astrophysical Journal
Wide-field high-precision photometric observations such as the Transiting Exoplanet Survey Satellite (TESS) allowed the investigation of the stellar magnetic activity of cool stars. M dwarf starspots and stellar flares are the main indicators of magnetic

Stellar magnetic field manifestations: flares

open access: yes, 2023
Understanding stellar magnetic fields is crucial to understanding the structure and evolution of stars. Stellar magnetic fields manifest in many different ways, on many different time scales. In this talk discuss one manifestations of magnetic fields on cool stars: stellar flares.

American College of Rheumatology Guidance Statement for Diagnosis and Management of VEXAS Developed by the International VEXAS Working Group Expert Panel

open access: yesArthritis &Rheumatology, EarlyView.
Objective Vacuoles E1 enzyme X‐linked autoinflammatory somatic syndrome (VEXAS) is a recently identified rare genetic disorder associated with somatic mutations in the UBA1 gene. VEXAS presents with a combination of inflammatory and hematologic manifestations, leading to increased morbidity and mortality.

Case‐Based Immunology: B Cells and Systemic Sclerosis Interstitial Lung Disease

open access: yesArthritis &Rheumatology, EarlyView.
Interstitial lung disease (ILD) is an important complication of systemic sclerosis (SSc), with high mortality and morbidity. Recent clinical studies in SSc‐ILD have led to US Food and Drug Administration–approved therapies in SSc‐ILD. Importantly, evidence from these studies has been extrapolated to guide management of ILDs of other systemic autoimmune
