Coupled fluid-structure interactions of natural convection in a ferrofluid using ISPH method

Alexandria Engineering Journal, 2019
This study aims to use incompressible version of smoothed particle hydrodynamics (ISPH) method for simulating natural convection flow of hot sloshing baffle inside a ferrofluid-filled cavity including the motion of cold circular cylinder.

Structure and Function of Four Classes of the 4Fe–4S Protein, IspH [PDF]

Biochemistry, 2016
IspH, (E)-1-hydroxy-2-methyl-but-2-enyl 4-diphosphate reductase, is an essential enzyme in isoprenoid biosynthesis and an important drug/herbicide target. Using X-ray crystallographic, bioinformatics, mutagenesis/kinetics/stability, and electron paramagnetic resonance (EPR) results, we show that organisms from different environments ultilize one of ...

HIV Care Coordination promotes care re-engagement and viral suppression among people who have been out of HIV medical care: an observational effectiveness study using a surveillance-based contemporaneous comparison group

AIDS Research and Therapy, 2021
Background Medical care re-engagement is critical to suppressing viral load and preventing HIV transmission, morbidity and mortality, yet few rigorous intervention studies address this outcome.

Optimal Dose and Safety of Intravenous Favipiravir in Hospitalized Patients With COVID‐19: A Dose‐Escalating, Randomized Controlled Phase Ib Study

Clinical Pharmacology &Therapeutics, Volume 119, Issue 6, Page 1650-1661, June 2026.
AGILE (NCT04746183) is a Phase Ib/IIa platform, evaluating candidates to treat COVID‐19. Candidate Specific Trial 6 evaluated the safety and optimal dose of a novel intravenous formulation of favipiravir in a dose‐escalating, open‐label, randomized, controlled, Bayesian adaptive Phase Ib trial.

Hepatitis C virus risk among young people who inject drugs

Frontiers in Public Health, 2022
BackgroundInjection drug use (IDU) is the leading risk factor for hepatitis C virus (HCV) transmission in the U.S. While the general risk factors for HCV transmission are known, there is limited work on how these factors interact and impact young people ...

Vector bundles on bielliptic surfaces: Ulrich bundles and degree of irrationality

Mathematische Nachrichten, Volume 299, Issue 3, Page 514-528, March 2026.
Abstract This paper deals with two problems about vector bundles on bielliptic surfaces. The first is to give a classification of Ulrich bundles on such surfaces S$S$, which depends on the topological type of S$S$. In doing so, we study the weak Brill–Noether property for moduli spaces of sheaves with isotropic Mukai vector. Adapting an idea of Moretti
