Trusted frequency region of convergence for the enclosure method in an inverse heat equation
Masaru Ikehata, Kiwoon Kwon
This paper is concerned with the numerical implementation of a formula in the enclosure method as applied to a prototype inverse initial boundary value problem for thermal imaging…
Distinct Reconstruction Patterns and Spin-Resolved Electronic States along the Zigzag Edges of Transition Metal Dichalcogenides
Ping Cui, Jin-Ho Choi, Wei Chen +5
Two-dimensional transition metal dichalcogenides represent an emerging class of materials exhibiting various intriguing properties, and integration of such materials for potential…
Gate-Tunable Spin Transport and Giant Electroresistance in Ferromagnetic Graphene Vertical Heterostructures
Nojoon Myoung, Hee Chul Park, Seung Joo Lee
We investigate spin transport through ferromagnetic graphene vertical heterostructures where a sandwiched tunneling layer is either a normal or ferroelectric insulator. We show tha…
Characteristics of neutrons and proton beams arising from two different Beam Nozzles
Yeon-Gyeong Choi, Yu-Seok Kim
Tandem or Van de Graaff accelerator with an energy of 3-MeV is typically used for PIXE analysis. In this study, the beam line design used in PIXE analysis was used to increase the…
High-Voltage Terminal Test of Test Stand for 1-MV Electrostatic Accelerator
Sae-Hoon Park, Yu-Seok Kim
The Korea Multipurpose Accelerator Complex (KOMAC) has been developing a 300-kV test stand for a 1-MV electrostatic accelerator ion source. The ion source and accelerating tube wil…
On Kurzweil's 0-1 Law in Inhomogeneous Diophantine Approximation
Michael Fuchs, Dong Han Kim
We give a sufficient and necessary condition such that for almost all \[ \|nθ-s\|<ψ(n)\qquad\text{for infinitely many}\ n\in{\mathbb N}, \] where is fixed and…
