Gas flow in close binary star systems [PDF]
arXiv, 2004 We first present a summary of our numerical work on accretion discs in close binary systems. Our recent studies on numerical simulations of the surface flow on the mass-losing star in a close binary star is then reviewed.
arxiv
Odessa Astronomical Publications, 2014 As is shown in the present computations performed using three-dimensional numerical astrophysical methods, in microquasars in the course of precession of the accretion disc blown by the donor’s wind the on- and off-states start being generated in the ...

Diagnostic Challenge in Frontal Variant Alzheimer's Disease With Low Amyloid‐β PET Retention
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Diagnosing frontal variant Alzheimer's disease (fvAD) is difficult and could be even more difficult when amyloid‐beta (Aβ) PET retention is low. A 63‐year‐old woman presenting with a 3‐year history of apathy and memory impairment showed executive dysfunction, memory impairment, and severe bilateral frontotemporal atrophy on MRI.

A Possible Explanation of W-type Phenomena in V694 Peg
The Astrophysical JournalThree sets of complete multicolor light curves of V694 Peg observed in 2013, 2015, and 2019 were presented and analyzed. Our photometric solutions show that this system was an A-type shallow contact binary in 2013 and 2015 while it converted to a W-type ...

Abnormal Synchronization Between Cortical Delta Power and Ripples in Hippocampal Sclerosis
Annals of Clinical and Translational Neurology, EarlyView.ABSTRACT Objective Discriminating between epileptogenic and physiological ripples in the hippocampus is important for identifying epileptogenic (EP) zones; however, distinguishing these ripples on the basis of their waveforms is difficult. We hypothesized that the nocturnal synchronization of hippocampal ripples and cortical delta power could be used ...

Carbon Stars from Gaia Data Release 3 and the Space Density of Dwarf Carbon Stars
The Astrophysical JournalCarbon stars (with atmospheric C/O > 1) range widely in temperature and luminosity, from low-mass dwarfs to asymptotic giant branch (AGB) stars. The main-sequence dwarf carbon (dC) stars have inherited carbon-rich material from an AGB companion, which ...

Arthritis Care &Research, EarlyView.Objective Osteoporosis, a known complication of rheumatoid arthritis (RA), increases the risk of hip fracture, which is associated with high morbidity and mortality. Fracture risk estimates in patients with RA treated with contemporary treatment strategies are lacking.

Arthritis Care &Research, Accepted Article.As many patients with inflammatory arthritis (IA) have chronic pain, understanding how to best assess and manage pain in IA is a priority. Co‐morbid depression is prevalent in adults with IA, affecting 15 to 39% of people. Whilst pain and depression are thought to be associated in IA, this concept is largely based on cross‐sectional data.

A Novel Digitalization Approach for Smart Materials – Ontology‐Based Access to Data and Models
Advanced Engineering Materials, EarlyView.In order to access heterogeneous material data and model‐based knowledge, the established ontology‐based data access (OBDA) is extended to include material models. This novel ontology‐based data and model access (OBDMA) enables the computation of new responses beyond stored data.

A Brown Dwarf Orbiting around the Planetary-nebula Central Binary KV Vel
The Astrophysical JournalKV Vel is a noneclipsing short-period ( P = 0.3571 days) close binary containing a very hot subdwarf primary (77,000 K) and a cool low-mass secondary star (3400 K) that is located at the center of the planetary nebula DS 1.
