Quantum critical scaling for finite temperature Mott-like metal-insulator crossover in a few layered-MoS
Byoung Hee Moon, Gang Hee Han, Miloš M. Radonjić +2
The possibility of the strong electron-electron interaction driven insulating phase from the metallic phase in two-dimensions has been suggested for clean systems without intention…
NuSTAR Discovery of Dead Quasar Engine in Arp 187
Kohei Ichikawa, Taiki Kawamuro, Megumi Shidatsu +7
Recent active galactic nucleus (AGN) and quasar surveys have revealed a population showing rapid AGN luminosity variability by a factor of . Here we present the most drasti…
Unsupervised Deformable Image Registration Using Cycle-Consistent CNN
Boah Kim, Jieun Kim, June-Goo Lee +3
Medical image registration is one of the key processing steps for biomedical image analysis such as cancer diagnosis. Recently, deep learning based supervised and unsupervised imag…
Effects of Janus Oscillators in the Kuramoto Model with Positive and Negative Couplings
Jungzae Choi, MooYoung Choi, Byung-Gook Yoon
We study the effects of Janus oscillators in a system of phase oscillators in which the coupling constants take both positive and negative values. Janus oscillators may also form a…
Néel-type skyrmions and their current-induced motion in van der Waals ferromagnet-based heterostructures
Tae-Eon Park, Licong Peng, Jinghua Liang +23
Since the discovery of ferromagnetic two-dimensional (2D) van der Waals (vdW) crystals, significant interest on such 2D magnets has emerged, inspired by their appealing properties…
Positive and negative feedback of AGN outflows in NGC 5728
Jaejin Shin, Jong-Hak Woo, Aeree Chung +4
We present a spatially-resolved analysis of ionized and molecular gas in a nearby Seyfert 2 galaxy NGC 5728, using the VLT/MUSE and ALMA data. We find ionized gas outflows out to ~…
