Electromagnetic draping of merging neutron stars.

Published: February 2023

We first derive a set of equations describing general stationary configurations of relativistic force-free plasma, without assuming any geometric symmetries. We then demonstrate that electromagnetic interaction of merging neutron stars is necessarily dissipative due to the effect of electromagnetic draping-creation of dissipative regions near the star (in the single magnetized case) or at the magnetospheric boundary (in the double magnetized case). Our results indicate that even in the single magnetized case we expect that relativistic jets (or "tongues") are produced, with correspondingly beamed emission pattern.

Importance: In the Atrial Cardiopathy and Antithrombotic Drugs in Prevention After Cryptogenic Stroke (ARCADIA) randomized clinical trial, anticoagulation did not prevent recurrent stroke among patients with a recent cryptogenic stroke and atrial cardiopathy. It is unknown whether anticoagulation prevents covert infarcts in this population.

Objective: To test the use of apixaban vs aspirin for prevention of nonlacunar covert infarcts after cryptogenic stroke in patients with atrial cardiopathy.

Solvent influence on the optical absorption, frontier molecular orbitals, and electronic structure of 1-bromo adamantane.

J Mol Model

January 2025

Applied Nuclear Technology in Geosciences Key Laboratory of Sichuan Province, Chengdu University of Technology, Chengdu, People's Republic of China.

Context: The study of the influence of solvent on 1-bromo adamantane (BAD) exposes prominent solvatochromatic shifts in the optical absorbance and substantial solvent effects on the electronic structure. This facilitates the molecular probe abilities for the BAD with respect to the surrounding environments such as dielectric constant and polarity. BAD exhibits positive solvatochromism for nonpolar solvents and negative solvatochromatic shifts for polar and aromatic solvents.

Arrhythmogenic Right Ventricular Cardiomyopathy in Monozygotic Twins-A Case Report.

J Clin Ultrasound

January 2025

Department of Gastroenterology, The Second Hospital, Cheeloo College of Medicine, Shandong University, Jinan, China.

Arrhythmogenic right ventricular cardiomyopathy (ARVC) is the classic phenotype of arrhythmogenic cardiomyopathy. ARVC in twins have been reported rarely. Herein, we report an unusual case of young monozygotic twins with early disease onset presenting different course of disease progression and clinical manifestations.

Summary: Hypophosphatasia (HPP) is a genetic disorder due to pathological variants in ALPL, the gene encoding tissue-nonspecific alkaline phosphatase (ALP). HPP is typically associated with bone-related symptoms, such as bone deformity, fractures and bone pain in children, but can appear in adults with symptoms resembling arthritis. A 22-year-old male experienced repeated and severe sudden attacks of joint pain in the elbows and knees.

Laparoscopic surgery for giant retroperitoneal lymphangioma: a case report.

J Surg Case Rep

January 2025

Department of Hepatobiliary Surgery, YiChun City People's Hospital, 1061 Jinxiu Avenue, Yichun 336000, Jiangxi, China.

This case report describes a 66-year-old male diagnosed with a giant retroperitoneal lymphangioma, presenting with an abdominal mass confirmed via magnetic resonance imaging (MRI). Laparoscopic surgery was successfully performed to excise the mass, with histopathological examination confirming the diagnosis. The patient's postoperative recovery was uneventful, with no signs of recurrence or metastasis observed at the three-month follow-up.
