The R Stars: Carbon Stars of a Different Kind [PDF]

open access: yesPublications of the Astronomical Society of the Pacific, 1997
After 16 years of radial-velocity observations of a sample of 22 R-type carbon stars, no evidence for binary motion has been detected in any of them. This is surprising considering that approximately 20% of normal late-type giants are spectroscopic binaries, and the fraction is close to 100% in barium, CH, and subgiant/dwarf CH and barium stars.

Diagnostic Utility of Testing for Novel Murine Autoantibodies for Sjögren's Disease in the Rheumatology Outpatient Setting

open access: yesArthritis Care &Research, Accepted Article.
Objective The goal was to assess the diagnostic performance of three novel autoantibodies (NA) for Sjögren's disease (SjD) by comparing NA prevalence in patients with SjD, other autoimmune rheumatic diseases (ARDs), nonspecific chronic sialadenitis (CS), and controls.

MYCOPHENOLATE MOFETIL TREATMENT REDUCES THE RISK OF TREATMENT ESCALATION DUE TO VASCULAR COMPLICATIONS IN LIMITED CUTANEOUS SYSTEMIC SCLEROSIS: EMULATION OF A TARGET TRIAL FROM ITALIAN RHEUMATOLOGY SOCIETY SPRING REGISTRY

open access: yesArthritis Care &Research, Accepted Article.
Objective Mycophenolate Mofetil (MMF) use in limited cutaneous systemic sclerosis (lcSSc) is relatively uncommon due to the lower fibrotic burden and the predominance of the vascular complications. In vitro observations and clinical data from transplanted patients suggest a protective effect of MMF on endothelial function.

MODEL ATMOSPHERES OF PECULAR CARBON GIANTS

open access: yesOdessa Astronomical Publications, 2008
We calculated 240 model atmospheres of carbon giants of high carbon abundances (2800 ≤ Teff ≤ 3400 K, 0.06 ≤ log(C/O) ≤ 2.7). The set of models was calculated in process of analysis by spectral synthesis of spectral energy distribution of the evolved ...

Marked Long‐term Improvement in Lung Function in Melanoma Differentiation‐associated Protein 5 (MDA5) Antibody Positive Dermatomyositis Patients: Experience of a Single Center Longitudinal Cohort in North America

open access: yesArthritis Care &Research, Accepted Article.
Objective The objective of this study was to describe the longitudinal disease course and pulmonary outcomes of North American patients with melanoma differentiation‐associated gene 5 antibody (MDA5 ab) associated dermatomyositis (DM). Methods Thirty patients with MDA5 ab DM were identified in a single center longitudinal cohort of 352 patients with ...

Mechanochemical Synthesis and Characterization of Nanostructured ErB4 and NdB4 Rare‐Earth Tetraborides

open access: yesAdvanced Engineering Materials, Volume 27, Issue 6, March 2025.
ErB4 and NdB4 nanostructured powders are produced by mechanochemical synthesis. 5 h mechanical alloying and 4 M HCl acid leaching are used in the production. ErB4 and NdB4 powders exhibit maximum magnetization of 0.4726 emu g−1 accompanied with an antiferromagnetic‐to‐paramagnetic phase transition at about TN = 18 K and 0.132 emu g−1 with a maximum at ...

Do ESG-superstar firms inhibit the ESG performance of their industry peers?

open access: yesInternational Review of Economics & Finance
Corporate ESG (Environmental, Social, and Governance) practices play a vital role in sustainable development. As industry leaders, ESG star companies set an example that promotes overall progress but may also cause inefficient ESG escalation among ...
