The Experimental Program for High Pressure Gas Filled Radio Frequency Cavities for Muon Cooling Channels
Ben Freemire, Moses Chung, Pierrick M. Hanlet +4
An intense beam of muons is needed to provide a luminosity on the order of 10 cms for a multi-TeV collider. Because muons produced by colliding a multi-MW prot…
The effect of time-varying flow-shear on the nonlinear stability of the boundary of magnetized toroidal plasmas
Youngmin Oh, Hyung Ju Hwang, Michael Leconte +1
We propose a phenomenological yet very general model in a form of generalized complex Ginzburg-Landau equation to understand the dynamics of the quasi-periodic fluid instabilities…
Cosmic Magnetism in Centimeter and Meter Wavelength Radio Astronomy
Takuya Akahori, Hiroyuki Nakanishi, Yoshiaki Sofue +13
Magnetic field is ubiquitous in the Universe and it plays essential roles in various astrophysical phenomena, yet its real origin and evolution are poorly known. This article revie…
Finite generation of the algebra of type A conformal blocks via birational geometry
Han-Bom Moon, Sang-Bum Yoo
We study birational geometry of the moduli space of parabolic bundles over a projective line, in the framework of Mori's program. We show that the moduli space is a Mori dream spac…
Compressed Sensing MRI Reconstruction using a Generative Adversarial Network with a Cyclic Loss
Tran Minh Quan, Thanh Nguyen-Duc, Won-Ki Jeong
Compressed Sensing MRI (CS-MRI) has provided theoretical foundations upon which the time-consuming MRI acquisition process can be accelerated. However, it primarily relies on itera…
Rapid X-ray variations of the Geminga pulsar wind nebula
C. Y. Hui, Jongsu Lee, A. K. H. Kong +4
A recent study by Posselt et al. (2017) reported the deepest X-ray investigation of the Geminga pulsar wind nebula (PWN) by using \emph{Chandra X-ray Observatory}. In comparison wi…
Hybrid integration of solid-state quantum emitters on a silicon photonic chip
Je-Hyung Kim, Shahriar Aghaeimeibodi, Christopher J. K. Richardson +3
Scalable quantum photonic systems require efficient single photon sources coupled to integrated photonic devices. Solid-state quantum emitters can generate single photons with high…
Growing Surface Tension of Amorphous-Amorphous Interfaces on Approaching the Colloidal Glass Transition
Divya Ganapathi, Hima K Nagamanasa, A. K. Sood +1
There is mounting evidence indicating that relaxation dynamics in liquids approaching their glass transition not only becomes increasingly cooperative (1,2) but the relaxing region…
AWAKE readiness for the study of the seeded self-modulation of a 400\,GeV proton bunch
P. Muggli, E. Adli, R. Apsimon +104
AWAKE is a proton-driven plasma wakefield acceleration experiment. % We show that the experimental setup briefly described here is ready for systematic study of the seeded self-mod…
Extreme Low Resolution Activity Recognition with Multi-Siamese Embedding Learning
Michael S. Ryoo, Kiyoon Kim, Hyun Jong Yang
This paper presents an approach for recognizing human activities from extreme low resolution (e.g., 16x12) videos. Extreme low resolution recognition is not only necessary for anal…
Intrinsic Rippling Enhances Static Non-Reciprocity in Graphene Metamaterials
Duc Tam Ho, Harold Park, Sung Youb Kim
In mechanical systems, Maxwell-Betti reciprocity means that the displacement at point B in response to a force at point A is the same as the displacement at point A in response to…
Acceleration of Cosmic Ray Electrons at Weak Shocks in Galaxy Clusters
Hyesung Kang, Dongsu Ryu, T. W. Jones
According to structure formation simulations, weak shocks with typical Mach number, , are expected to form in merging galaxy clusters. The presence of such sho…
ssEMnet: Serial-section Electron Microscopy Image Registration using a Spatial Transformer Network with Learned Features
Inwan Yoo, David G. C. Hildebrand, Willie F. Tobin +2
The alignment of serial-section electron microscopy (ssEM) images is critical for efforts in neuroscience that seek to reconstruct neuronal circuits. However, each ssEM plane conta…
