Detection of Low Mass-ratio Stellar Binary Systems

open access: yes, 2012
O- and B-type stars are often found in binary systems, but the low binary mass-ratio regime is relatively unexplored due to observational difficulties.

Analysis of Soluble Interleukin‐2 Receptor as a Prognostic Biomarker in NMOSD and MOGAD

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Soluble interleukin‐2 receptor (sIL‐2R) is a biomarker for T cell activity. T cells are involved in neuromyelitis optica spectrum disorders (NMOSD) and myelin oligodendrocyte glycoprotein antibody‐associated disease (MOGAD) pathogenesis. However, sIL‐2R has so far not been evaluated in these conditions.

Detecting New Visual Binaries in Gaia DR3 with Gaia and Two Micron All Sky Survey (2MASS) Photometry. I. New Candidate Binaries within 200 pc of the Sun

open access: yesThe Astronomical Journal, 2023
We present a method to identify likely visual binaries in Gaia eDR3 that does not rely on parallax or proper motion. This method utilizes the various point-spread function sizes of Two Micron All Sky Survey (2MASS)/Gaia, where at

Multi-messenger Observations of a Binary Neutron Star Merger

open access: yesProceedings of Multifrequency Behaviour of High Energy Cosmic Sources - XIII — PoS(MULTIF2019), 2019
On 2017 August 17 a binary neutron star coalescence candidate (later designated GW170817) with merger time 12:41:04 UTC was observed through gravitational waves by the Advanced LIGO and Advanced Virgo detectors.

Lesion Location and Functional Connections Reveal Cognitive Impairment Networks in Multiple Sclerosis

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Objective Cognitive impairment, fatigue, and depression are common in multiple sclerosis (MS), potentially due to disruption of regional functional connectivity caused by white matter (WM) lesions. We explored whether WM lesions functionally connected to specific brain regions contribute to these MS‐related manifestations.

Characterization of Low-mass Companions to Kepler Objects of Interest Observed with APOGEE-N

open access: yesThe Astrophysical Journal Supplement Series, 2023
We report the characterization of 28 low-mass (0.02 M _⊙ ≤ M _2 ≤ 0.25 M _⊙ ) companions to Kepler objects of interest (KOIs), eight of which were previously designated confirmed planets.

Stellar activity and planetary atmosphere evolution in tight binary star systems

open access: yes, 2019
Context. In tight binary star systems, tidal interactions can significantly influence the rotational and orbital evolution of both stars, and therefore their activity evolution.

The Impact of Tilburg Frailty on Poststroke Fatigue in First‐Ever Stroke Patients: A Cross‐Sectional Study With Unified Measurement Tools and Improved Statistics

open access: yesAnnals of Clinical and Translational Neurology, EarlyView.
ABSTRACT Background Poststroke fatigue (PSF) and frailty share substantial overlap in their manifestations, yet previous research has yielded conflicting results due to the use of heterogeneous frailty assessment tools. Objective To evaluate the independent impact of frailty on PSF using a unified measurement system (Tilburg Frailty Indicator, TFI ...

Color-Induced Displacement double stars in SDSS

open access: yes, 2004
We report the first successful application of the astrometric color-induced displacement technique (CID, the displacement of the photocenter between different bandpasses due to a varying contribution of differently colored components to the total light),
