Performance Analysis of License Assisted Access LTE with Asymmetric Hidden Terminals
H. R. Lee, H. Kim, H. J. Yang +2
License Assisted Access (LAA) LTE (LTE-LAA) is a new type of LTE that aggregates the licensed LTE bands with the unlicensed bands via carrier aggregation. To operate in unlicensed…
Molecule-Induced Conformational Change in Boron Nitride Nanosheets with Enhanced Surface Adsorption
Qiran Cai, Aijun Du, Guoping Gao +11
Surface interaction is extremely important to both fundamental research and practical application. Physisorption can induce shape and structural distortion (i.e. conformational cha…
Imaging of interlayer coupling in van der Waals heterostructures using a bright-field optical microscope
Evgeny M. Alexeev, Alessandro Catanzaro, Oleksandr V. Skrypka +8
Vertically stacked atomic layers from different layered crystals can be held together by van der Waals forces, which can be used for building novel heterostructures, offering a pla…
The Effective Temperature Concept Tested in an Active Colloid Mixture
Ming Han, Jing Yan, Steve Granick +1
Thermal energy agitates all matter and its competition with ordering tendencies is one of the most fundamental organizing principles in the physical world. Thus, it is natural to e…
An unconstrained framework for eigenvalue problems
Yunho Kim
In this paper, we propose an unconstrained framework for eigenvalue problems in both discrete and continuous settings. We begin our discussion to solve a generalized eigenvalue pro…
Physics Potentials with the Second Hyper-Kamiokande Detector in Korea
Hyper-Kamiokande proto-collaboration, :, K. Abe +353
Hyper-Kamiokande consists of two identical water-Cherenkov detectors of total 520~kt with the first one in Japan at 295~km from the J-PARC neutrino beam with 2.5 Off…
On the Schertz conjecture
Ja Kyung Koo, Dong Sung Yoon
Schertz conjectured that every finite abelian extension of imaginary quadratic fields can be generated by the norm of the Siegel-Ramachandra invariants. We shall present a conditio…
Generalized Kapchinskij-Vladimirskij Distribution and Beam Matrix for Phase-Space Manipulations of High-Intensity Beams
Moses Chung, Hong Qin, Ronald C. Davidson +2
In an uncoupled linear lattice system, the Kapchinskij-Vladimirskij (KV) distribution, formulated on the basis of the single-particle Courant-Snyder (CS) invariants, has served as…
Auxetic Nanomaterials: Recent Progress and Future Development
Jin-Wu Jiang, Sung Youb Kim, Harold S. Park
Auxetic materials (materials with negative Poisson's ratio) and nanomaterials have independently been for many years two of the most active research fields in material science. Rec…
Opportunistic Network Decoupling With Virtual Full-Duplex Operation in Multi-Source Interfering Relay Networks
Won-Yong Shin, Vien V. Mai, Bang Chul Jung +1
We introduce a new achievability scheme, termed opportunistic network decoupling (OND), operating in virtual full-duplex mode. In the scheme, a novel relay scheduling strategy is u…
Transmodal Fabry-Pérot Resonance: Theory and Realization with Elastic Metamaterials
Joshua Minwoo Kweun, Hyung Jin Lee, Joo Hwan Oh +2
We discovered a new transmodal Fabry-Pérot resonance that one elastic-wave mode is maximally transmitted to another when the phase difference of two dissimilar modes through an ani…
Turbulence and Vorticity in Galaxy Clusters Generated by Structure Formation
F. Vazza, T. W. Jones, M. Brüggen +4
Turbulence is a key ingredient for the evolution of the intracluster medium, whose properties can be predicted with high resolution numerical simulations. We present initial result…
Inversion of the attenuated V-line transform for SPECT with Compton cameras
Markus Haltmeier, Sunghwan Moon, Daniela Schiefeneder
The Compton camera is a promising alternative to the Anger camera for imaging gamma radiation, with the potential to significantly increase the sensitivity of SPECT. Two-dimensiona…
Global existence of weak solutions to dissipative transport equations with nonlocal velocity
Hantaek Bae, Rafael Granero-Belinchón, Omar Lazar
We consider 1D dissipative transport equations with nonlocal velocity field: \[ θ_t+uθ_x+δu_{x} θ+Λ^γθ=0, \quad u=\mathcal{N}(θ), \] where is a nonlocal operator give…
Simulations of Viscous Accretion Flow around Black Holes in Two-Dimensional Cylindrical Geometry
Seong-Jae Lee, Indranil Chattopadhyay, Rajiv Kumar +2
We simulate shock-free and shocked viscous accretion flow onto a black hole in a two dimensional cylindrical geometry, where initial conditions were chosen from analytical solution…
Determination of the thickness and orientation of few-layer tungsten ditelluride using polarized Raman spectroscopy
Minjung Kim, Songhee Han, Jung Hwa Kim +3
Orthorhombic tungsten ditelluride (WTe2), with a distorted 1T structure, exhibits a large magnetoresistance that depends on the orientation, and its electrical characteristics chan…
Higher Hickerson formula
Jungyun Lee, Byungheup Jun, Hi-joon Chae
Hickerson made an explicit formula for Dedekind sums in terms of the continued fraction of . We develop analogous formula for generalized Dedekind sums …
Search for EeV Protons of Galactic Origin
R. U. Abbasi, M. Abe, T. Abu-Zayyad +126
Cosmic rays in the energy range - eV are thought to have a light, probably protonic, composition. To study their origin one can search for anisotropy in the…
Physical model of the genotype-to-phenotype map of proteins
Tsvi Tlusty, Albert Libchaber, Jean-Pierre Eckmann
How DNA is mapped to functional proteins is a basic question of living matter. We introduce and study a physical model of protein evolution which suggests a mechanical basis for th…
