A 73‐Year‐Old Man With Several Years of Difficulty Climbing Stairs and Frequent Tripping

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT A 73‐year‐old man presented with progressive weakness and atrophy predominantly affecting the distal finger flexors and quadriceps muscles. Electrophysiological studies demonstrated mixed myogenic and neurogenic features. Muscle MRI showed inflammatory changes, and muscle biopsy revealed granulomatous myositis with histologic features ...

Amplitudes of solar-like oscillations in red giants: Departures from the quasi-adiabatic approximation

open access: yesEPJ Web of Conferences, 2013
CoRoT and Kepler measurements reveal us that the amplitudes of solar-like oscillations detected in red giant stars scale from stars to stars in a characteristic way. This observed scaling relation is not yet fully understood but constitutes potentially a

Dynamical Substructures of Galactic Globular Clusters I. M5 [PDF]

open access: yesJournal of Astronomy and Space Sciences, 2004
CCD images to study the dynamical substructure of the globular cluster M5. We investigate the radial variation of ellipticities and position angles using the stellar photometry and the IRAF ellipse task.

Multiple stellar populations in the Galactic globular cluster NGC 6752

open access: yes, 2009
We have carried out high-precision photometry on a large number of archival HST images of the Galactic globular cluster NGC 6752, to search for signs of multiple stellar populations. We find a broadened main sequence, and demonstrate that this broadening

Asteroseismology of red-clump stars with CoRoT and Kepler [PDF]

open access: yes, 2009
The availability of asteroseismic constraints for a large number of red giants with CoRoT and in the near future with Kepler, paves the way for detailed studies of populations of galactic-disk red giants.

Performance Characteristics of Anti‐Collagen II Antibodies in Relapsing Polychondritis and Related Diseases: Prospective Analysis, Systematic Review, and Meta‐Analysis

open access: yesArthritis Care &Research, Accepted Article.
Background Relapsing polychondritis (RP) is a rare disease defined by recurrent cartilaginous inflammation. Anti‐collagen II (anti‐Col2) antibodies have been proposed as a diagnostic biomarker for RP, but their performance characteristics are not well defined.

Symbiotic Stars (Including T Corona Borealis) Are Not Immediate Progenitors of Normal Type Ia Supernovae

open access: yesThe Astrophysical Journal
A popular solution to the Type Ia supernova (SN Ia) progenitor problem is that the immediate progenitors are symbiotic star systems. This solution requires that the companion star of the exploding white dwarf must be a red giant star with a heavy stellar

Recent Advancements in Bulk Processing of Rare‐Earth‐Free Hard Magnetic Materials and Related Multiscale Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
This article provides an overview of recent advancements in bulk processing of rare‐earth‐free hard magnetic materials. It also addresses related simulation approaches at different scales. The research on rare‐earth‐free magnetic materials has increased significantly in recent years, driven by supply chain issues, environmental and social concerns, and
