Hyperon Puzzle of Neutron Stars with Skyrme Force Models
Yeunhwan Lim, Chang Ho Hyun, Kyujin Kwak +1
We consider the so called hyperon puzzle of neutron star (NS). We employ Skyrme force models for the description of in-medium nucleon-nucleon, nucleon-Lambda hyperon (), and La…
Designed Three-Dimensional Freestanding Single-Crystal Carbon Architectures
Ji-Hoon Park, Dae-Hyun Cho, Youngkwon Moon +6
Single-crystal carbon nanomaterials have led to great advances in nanotechnology. The first single-crystal carbon nanomaterial, fullerene, was fabricated in a zero-dimensional form…
Mixing between High Velocity Clouds and the Galactic Halo
Jeffrey A. Gritton, Robin L. Shelton, Kyujin Kwak
In the Galactic halo, metal-bearing Galactic halo material mixes into high velocity clouds (HVCs) as they hydrodynamically interact. This interaction begins long before the clouds…
Experimental Proof of Adjustable Single-Knob Ion Beam Emittance Partitioning
L. Groening, M. Maier, C. Xiao +7
The performance of accelerators profits from phase space tailoring by coupling of planes. The previously applied techniques swap the emittances among the three planes but the set o…
Selective metal deposition at graphene line defects by atomic layer deposition
Kwanpyo Kim, Han-Bo-Ram Lee, Richard W. Johnson +7
One-dimensional defects in graphene have strong influence on its physical properties, such as electrical charge transport and mechanical strength. With enhanced chemical reactivity…
Persistent Topological Surface State at the Interface of Bi2Se3 Film Grown on Patterned Graphene
Namdong Kim, Paengro Lee, Youngwook Kim +6
We employed graphene as a patternable template to protect the intrinsic surface states of thin films of topological insulators (TIs) from environment. Here we find that the graphen…
Global existence for some transport equations with nonlocal velocity
Hantaek Bae, Rafael Granero-Belinchón
In this paper, we study transport equations with nonlocal velocity fields with rough initial data. We address the global existence of weak solutions of an one dimensional model of…
Mesoscale Imperfections in MoS2 Atomic Layers Grown by Vapor Transport Technique
Yingnan Liu, Rudresh Ghosh, Di Wu +3
The success of isolating small flakes of atomically thin layers through mechanical exfoliation has triggered enormous research interest in graphene and other two-dimensional materi…
A Northern Sky Survey for Point-Like Sources of EeV Neutral Particles with the Telescope Array Experiment
R. U. Abbasi, M. Abe, T. Abu-Zayyad +122
We report on the search for steady point-like sources of neutral particles around 10 eV between 2008 May and 2013 May with the scintillator surface detector of the Telescope…
Faraday dispersion functions of galaxies
Shinsuke Ideguchi, Yuichi Tashiro, Takuya Akahori +2
The Faraday dispersion function (FDF), which can be derived from an observed polarization spec- trum by Faraday rotation measure synthesis, is a profile of polarized emissions as a…
Magnetic Structure of Hexagonal Mn-doped LuFeO
Steven M. Disseler, Xuan Luo, Yoon Seok Oh +6
Neutron scattering techniques are used to investigate the crystalline and magnetic structure of LuFeMnO in bulk polycrystalline form. We find that the cryst…
The Origin of the X-ray Emission from the High-velocity Cloud MS30.7-81.4-118
David B. Henley, Robin L. Shelton, Kyujin Kwak
A soft X-ray enhancement has recently been reported toward the high-velocity cloud MS30.7-81.4-118 (MS30.7), a constituent of the Magellanic Stream. In order to investigate the ori…
Statistical Techniques for Detecting the Intergalactic Magnetic Field from Large Samples of Extragalactic Faraday Rotation Data
Takuya Akahori, B. M. Gaensler, Dongsu Ryu
Rotation measure (RM) grids of extragalactic radio sources have been widely used for studying cosmic magnetism. But their potential for exploring the intergalactic magnetic field (…

Kiwan Park
We investigated the influence of small scale magnetic energy () and magnetic helicity () on the growth rate () of large scale magnetic field (). $H_M…
Load Balancing in Two-Tier Cellular Networks with Open and Hybrid Access Femtocells
Dongmyoung Kim, Taejun Park, Hyoil Kim +1
Femtocell base station (BS) is a low-power, low-price BS based on cellular communication technology. It is expected to become a cost-effective solution for improving the communicat…
Twisted Skyrmion String
Miftachul Hadi, Malcolm Anderson, Andri Husein
We study nonlinear sigma model, especially Skyrme model without twist and Skyrme model with twist: twisted Skyrmion string. Twist term, , is indicated in vortex solution. Nece…
Injection of -like Suprathermal Particles into Diffusive Shock Acceleration
Hyesung Kang, Vahe Petrosian, Dongsu Ryu +1
We consider a phenomenological model for the thermal leakage injection in the diffusive shock acceleration (DSA) process, in which suprathermal protons and electrons near the shock…
Breaking of symmetry in graphene growth on metal substrates
Vasilii I. Artyukhov, Yufeng Hao, Rodney S. Ruoff +1
In graphene growth, island symmetry can become lower than the intrinsic symmetries of both graphene and the substrate. First-principles calculations and Monte Carlo modeling explai…
