An MRI assessment of mechanisms underlying lesion growth and shrinkage in multiple sclerosis
Annals of Clinical and Translational Neurology, EarlyView.By applying the tensor model, we analysed lesion orientation and the directionality of lesion expansion/contraction in multiple sclerosis. Each lesion is summarized as an ellipsoid, and the tensor model is applied to calculate lesion anisotropy. From the top to the bottom white matter atlas, surface‐in gradient segmentation and venous atlas used in the

A model for high-energy emission of the Intrabinary shock in pulsar binaries
EPJ Web of Conferences, 2018 We present our studies of intrabinary shock emission for astrophysical binary systems with a neutron star. We construct a model for the shock emission and compare the model calculation with the light curve and the spectral energy distribution of the ...

Handling rescue therapy in myasthenia gravis clinical trials: why it matters and why you should care
Annals of Clinical and Translational Neurology, EarlyView.Abstract Myasthenia gravis (MG) clinical trials typically allow rescue therapy during follow‐up in the event of marked worsening of MG symptoms. Failure to appropriately address rescue therapy in defining treatment effects and planning statistical analyses may yield biased estimates, increase false positive rates, or decrease statistical power – all of

Symposium - International Astronomical Union, 1992 We assemble and discuss evidence for binarity in S and MS stars - stars that are enriched in s-process elements. A popular view is that Tc-deficient S and MS stars are not thermally pulsing AGB stars but are mass-transfer binaries. We describe several methods used to test this hypothesis through a search for the putative white-dwarf companion: (1 ...

Ejection of Stars with Relativistic Velocities
Open Astronomy, 2016 We present the results of numerical simulations performed in terms of modified Hills' scenario involving two supermassive black holes (SMBHs). In contrast to the classic Hills scenario (Hills 1988), here one component of the ordinary stellar binary ...

Cerebral autoregulation in patients with acute lacunar infarction: a reliable predictor of outcome
Annals of Clinical and Translational Neurology, EarlyView.Abstract Objective To further investigate the association between dynamic cerebral autoregulation (dCA) and the outcomes in patients with acute lacunar infarction. Methods Patients were prospectively and consecutively enrolled at The First Hospital of Jilin University between 2016 and 2023. dCA was monitored at 1–3 and 7–10 days after the stroke.

Nonlinear Dynamics, Lorenz Model and Formation of Binary Stars [PDF]
arXiv, 2008 Based on the Lorenz model derived from the equations of hydrodynamics of nebula, we discuss the formation of binary stars by the qualitative analysis theory of nonlinear equation. Here the two wings in the Lorenz model form just the binary stars, whose Roche surface is result of evolution under certain condition.

Spin–Orbit Alignment in Merging Binary Black Holes Following Collisions with Massive Stars
The Astrophysical Journal LettersMerging binary black holes (BBHs) formed dynamically in dense star clusters are expected to have uncorrelated spin–orbit orientations since they are assembled through many random interactions.

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.
