Developing a Typology of Korean Women Leaders' Resistance to Their Token Status in the Workplace

Human Resource Development Quarterly, EarlyView.
ABSTRACT Despite remarkable economic development in South Korea (Korea), there are only a few women leaders, and they face challenges in the gendered workplace where organizational constraints and traditional values coexist. In a reanalysis of narratives of Korean women leaders (KWLs), using an ideal‐type analysis as a novel qualitative research method,

Gap Symmetry, Electronic Structure and Interplay Between Superconductivity and Spin Density Wave in Sr1−xKxFe2As2 Superconductor

Nano Select, EarlyView.
In moderately hole‐doped Sr1−xKxFe2As2${\rm Sr}_{1-x}{\rm K}_x{\rm Fe}_2{\rm As}_2$ system the pairing state is s+−${\rm s}^{+-}$ wave pairing state mediated by spin fluctuations. As the SDW order parameter increases, TC${\rm T}_C$ decreases and TM${\rm T}_M$ increases. As temperature increases, the SDW order parameter decreases and vanishes at TM${\rm

Tunable Josephson Generator for Qubit Excitation and Two‐Tone Spectroscopy

Advanced Quantum Technologies, EarlyView.
A tunable on‐chip Josephson generator that enables direct qubit excitation has been presented. The device consists of a current‐biased Josephson junction and a superconducting resonator, forming a microwave source that operates at 4 K. Excitation of the qubit at 20 mK was done via a short coaxial line between the 4 K and 20 mK stages.

Digital Twin Simulations Toolbox of the Nitrogen‐Vacancy Center in Diamond

Advanced Quantum Technologies, EarlyView.
The Nitrogen‐vacancy (NV) center in diamond is a key platform within quantum technologies. This work introduces a Python based digital‐twin of the NV, where the spin dynamics of the system is simulated without relying on commonly used approximations, such as the adoption of rotating frame. The digital‐twin is validated through three different examples,

Composite‐Field Annealing Enables Superior High‐Temperature Noise Stability in Fluxgate Sensors With Co‐Rich Amorphous Microwires

Rare Metals, EarlyView.
ABSTRACT Fluxgate sensors with Co‐rich amorphous microwires, widely used for their low noise in magnetic field measurements, encounter significant challenges in high‐temperature environments such as well drilling and geological exploration. Prolonged thermal aging degrades the performance of Co‐rich amorphous microwires, resulting in increased noise ...

Subterranean Mine Inspection Using the Prometheus Re‐Configurable Drone

Journal of Field Robotics, EarlyView.
ABSTRACT This paper describes the design, development, and real‐world testing of an autonomous drone for subterranean exploration, known as “Prometheus.” Driven by requirements from industry that the drone be able to be deployed through areas of restricted access, Prometheus was designed to be directly deployed through a 150 mm aperture.

Ligand‐Driven Optimization of Iron Oxide Nanoprobes for In Vivo MRI Enhancement at Ultra‐High Field

Small, EarlyView.
Ligand‐tailored iron oxide nanoparticles reveal how surface chemistry controls T2 relaxivity and in vivo performance in ultra‐high‐field MRI. Systematic variation of hydrophilicity and charge across five coatings modulated r2 by up to 333 mm−1 s−1, with chemical properties, rather than shell thickness, dictating magnetic dephasing and enabling reliable

Modular Donor‐Acceptor Diradicaloids Based on an Electron Deficient N‐Heteroacene Acceptor

Small, EarlyView.
This work presents a modular approach to donor‐acceptor‐donor (D‐A‐D) diradicaloids that show systematic evolution of their energy gaps, singlet‐triplet splittings, and diradical character (y). The correlation of (opto)electronic, spin, and magnetic properties with high‐fidelity theoretical investigations provides clear connections between the degree ...

Synthesis of Large‐Area 2D Prussian Blue as Ion‐Transport Channels for Non‐Volatile Memristors

Small, EarlyView.
A robust liquid‐liquid interfacial synthesis enables continuous, large‐area 2D Prussian blue films with tunable thickness from ∼2 nm to hundreds of nanometers. Controlled reduction guides slow, directional layer growth, yielding high‐quality flakes. These films show exceptional ion transport and device integration, demonstrated in memristors with long ...

Engineering Grain Architecture in Epitaxial Aluminum on Miscut Substrates Toward Various Clean Limits and Giant Superconductivity Modulation

Small, EarlyView.
The miscut substrate strategy offers a novel means to engineer aluminum surface roughness, grain architecture, crystallinity, and both normal and superconducting transport properties toward their clean limits by precisely tuning the miscut angle without altering growth conditions.
