Effect of Trimethylamine‐N‐Oxide (TMAO) and Sorbitol on the Catalytic Activity of Candida boidinii Formate Dehydrogenase

open access: yesChemCatChem, EarlyView.
The effects of the osmolytes TMAO and sorbitol on the catalytic activity of Candida boidinii formate dehydrogenase are investigated using computational and experimental studies. The osmolytes exert different effects on the inter‐domain fluctuations, solvation, and active site dynamics of the enzyme as well as on the substrate residence times.

Oxygen Concentration Plays a Critical Role in Fibrinogen-Mediated Platelet Activation via Inactivation of αIIbβ3 and Modulation of Fibrinogen

open access: yesBiomolecules
In the vascular system, pathological conditions that cause hypoxia are associated with increased platelet activity and thrombosis. Using a platelet spreading assay, we show that severe hypoxia (i.e., 1%), venous (i.e., 5%), and, surprisingly, arterial (i.

A Case Study Exploration of Adolescents’ Experiences in a Paid Summer Internship Program

open access: yesThe Career Development Quarterly, EarlyView.
ABSTRACT Adolescence is a critical time for career exploration, and internships are a common tool to promote career development. Yet, few researchers have examined their impact on participants. In this study, we conducted a qualitative case study with adolescent participants (N = 19) in the City of Charlotte's Mayor's Youth Employment Program (MYEP), a

Analysis of density matrix embedding theory around the non‐interacting limit

open access: yesCommunications on Pure and Applied Mathematics, EarlyView.
Abstract This article provides the first mathematical analysis of the Density Matrix Embedding Theory (DMET) method. We prove that, under certain assumptions, (i) the exact ground‐state density matrix is a fixed‐point of the DMET map for non‐interacting systems, (ii) there exists a unique physical solution in the weakly‐interacting regime, and (iii ...

High‐Pressure Stability and Electronic Properties of Sodium‐Rich Nitrides: Insights from First‐Principles Calculations

open access: yesChemPhysChem, EarlyView.
This work highlights how pressure‐induced IAEs rearrangements influence the thermodynamic stability and electronic behavior of these compounds, including metal‐to‐semiconductor transitions in P63/mmc Na5N and superconductivity in C2/m Na8N. Abstract Using first‐principles structure search calculations, we investigated the phase stability of sodium ...
