Superconducting properties of thin film NbTiN studied via the NMR of implantedLi.

We report measurements of the normal-state and superconducting properties of thin-film NbTiN usingLi-detected nuclear magnetic resonance (-NMR). In these experiments, radioactiveLiprobes were implanted 21 nm below the surface of a NbTiN(91 nm) film in NbTiN/(91 nm)/AlN(4 nm)/Nb and its NMR response recorded (viaLi's-emissions) between 4.6 K and and 270 K in a 4.

Theoretical Insights into Enhanced Electrocatalytic Arsenic Oxidation on Au-Decorated Pt Surfaces in Neutral Medium.

In this study, we present a comprehensive theoretical and experimental investigation of the electrocatalytic oxidation of arsenite on Au immobilized Pt surfaces in a neutral medium. Theoratically, density functional theory (DFT) calculations revealed that thePt-Au bimetallic system exhibits superior adsorption energy (E = -2.045 eV) compared to bare Au (-0.

Exploring resilience as a mediator and moderator in the relationships between stress and depression among undergraduate medical students.

Background: There is evidence that physicians are more likely to experience stress and depression. Nonetheless, little is known about the role of resilience in the connection between stress and depression among undergraduate medical students. The purpose of this study was to investigate how resilience affects the association between stress and depression in undergraduate medical students by acting as a mediator and moderator.

Social and commercial determinants of inappropriate antibiotic use in resource-constrained settings: A social-ecological system framework analysis.

Background: Non-prescription antibiotic use is common in low- and middle-income countries, particularly in community-settings, yet research often overlooks social and commercial drivers beyond formal-healthcare.

Methods: This qualitative study conducted 64 in-depth interviews-16 each with pharmacy drug-sellers, pharmaceutical sales-representatives, registered-physicians, and antibiotic-users-across two urban and two rural areas in Bangladesh. Using a social-ecological systems framework, it examined how social-and-commercial determinants influence perceptions and practices in antibiotic marketing, prescription, dispensing, and use.

Optimizing electroporation via pulse modulation: a molecular dynamics study.

Efficient molecular transport via reversible electroporation requires sustained existence of the pore without causing irreversible cellular damage. In this study, we used molecular dynamics simulations to investigate pore formation during electroporation, and we characterized the transition to hydrophilic pores. Our simulations reveal that during the hydrophilic state, the reapplication of an electric field, even at reduced magnitudes, extends the pore duration while maintaining structural integrity.
