Coherent electron transmission across twin boundaries in Cu(111)

Jungin Yeo, Gee Hoon Lee, Su Jae Kim, Seong‐Gon Kim et autres

Copper thin films are foundational to modern electronics and nanotechnology, yet their charge transport is limited fundamentally by electron scattering at atomic-scale imperfections. Recent advances in atomic sputtering epitaxy (ASE) have enabled the growth of grain-boundary-free Cu(111) films, but defects such as …

Rule-Based Dynamic Braking Control of Pneumatic Electronic Parking Brake for Commercial Vehicles

Youngok Lee, Solyeon Kwon, Jae Seol Cho, M. Kwon et autres

Because of their substantial weight and high centers of gravity, commercial vehicles require braking systems that ensure maximum performance and safety. Accurate braking control is vital for preserving safe vehicle dynamics by preventing lateral instability due to excessive deceleration or rear-wheel lock-up. …

Flux pinning in superconducting multilayer 2H-NbSe2 nano-step junction

M. Kwon, Min Han Kim, Heeyeon Lee, Young Duck Kim

Abstract Superconductors exhibit dissipationless supercurrents even under finite bias and magnetic field conditions, provided these remain below the critical values. However, type-II superconductors in the flux flow regime display Ohmic dissipation arising from vortex dynamics under finite magnetic fields. The interplay between …

FRIDAY: Mitigating Unintentional Facial Identity in Deepfake Detectors Guided by Facial Recognizers

Y. I. Kim, M. Kwon, Wonjun Lee, Changick Kim

Previous Deepfake detection methods perform well within their training domains, but their effectiveness diminishes significantly with new synthesis techniques. Recent studies have revealed that detection models often create decision boundaries based on facial identity rather than synthetic artifacts, resulting in poor performance …

FRIDAY: Mitigating Unintentional Facial Identity in Deepfake Detectors Guided by Facial Recognizers

Younghun Kim, M. Kwon, Wonjun Lee, Changick Kim

Previous Deepfake detection methods perform well within their training domains, but their effectiveness diminishes significantly with new synthesis techniques. Recent studies have revealed that detection models make decision boundaries based on facial identity instead of synthetic artifacts, leading to poor cross-domain performance. …

Spin-orbit-splitting-driven nonlinear Hall effect in NbIrTe4

Ji‐Eun Lee, Aifeng Wang, Shuzhang Chen, M. Kwon et autres

Abstract The Berry curvature dipole (BCD) serves as a one of the fundamental contributors to emergence of the nonlinear Hall effect (NLHE). Despite intense interest due to its potential for new technologies reaching beyond the quantum efficiency limit, the interplay between BCD …

An overview of KSTAR results

J.G. Kwak, Y.K. Oh, H.L. Yang, K.R. Park et autres

Since the first H-mode discharges in 2010, the duration of the H-mode state has been extended and a significantly wider operational window of plasma parameters has been attained. Using a second neutral beam (NB) source and improved tuning of equilibrium configuration with …
