Frequency comb-based microwave transfer over fiber with instability using fiber-loop optical-microwave phase detectors
Kwangyun Jung, Junho Shin, Jinho Kang +3
We demonstrate a remote microwave/radio-frequency (RF) transfer technique based on the stabilization of a fiber link using a fiber-loop optical-microwave phase detector (FLOM-PD).…
A Novel High-Pressure Monoclinic Metallic Phase of V2O3
Yang Ding, Cheng-Chien Chen, Qiaoshi Zeng +11
Vanadium sesquioxide, V2O3, is a prototypical metal-to-insulator system where, in temperature-dependent studies, the transition always coincides with a corundum-to-monoclinic struc…
Concatenated Raptor Codes in NAND Flash Memory
Geunyeong Yu, Jaekyun Moon
Two concatenated coding schemes based on fixed-rate Raptor codes are proposed for error control in NAND flash memory. One is geared for off-line recovery of uncorrectable pages and…
Characterization of the gradient blow-up of the solution to the conductivity equation in the presence of adjacent circular inclusions
Mikyoung Lim, Sanghyeon Yu
We consider the conductivity problem in the presence of adjacent circular inclusions having arbitrary constant conductivity. When two inclusions get closer and their conductivities…
Opportunistic Downlink Interference Alignment
Hyun Jong Yang, Won-Yong Shin, Bang Chul Jung +2
In this paper, we propose an opportunistic downlink interference alignment (ODIA) for interference-limited cellular downlink, which intelligently combines user scheduling and downl…
Constraints on composite quark partners from Higgs searches
Thomas Flacke, Jeong Han Kim, Seung J. Lee +1
In composite Higgs models, the generation of quark masses requires the standard model-like quarks to be partially or fully composite states which are accompanied by composite quark…
Small knot mosaics and partition matrices
Kyungpyo Hong, Ho Lee, Hwa Jeong Lee +1
Lomonaco and Kauffman introduced knot mosaic system to give a definition of quantum knot system. This definition is intended to represent an actual physical quantum system. A knot…
Generalized epidemic process on modular networks
Kihong Chung, Yongjoo Baek, Daniel Kim +2
Social reinforcement and modular structure are two salient features observed in the spreading of behavior through social contacts. In order to investigate the interplay between the…
Structure, strain, and control of ground state property in LaTiO/LaAlO superlattice
Alex Taekyung Lee, Myung Joon Han
Using first-principles density functional theory calculations, we examined the ground state property of LaTiO/LaAlO superlattice. Total energy calculations, taking account…
Gigahertz repetition rate, sub-femtosecond timing jitter optical pulse train directly generated from a mode-locked Yb:KYW laser
Heewon Yang, Hyoji Kim, Junho Shin +5
We show that a 1.13-GHz repetition rate optical pulse train with 0.70 fs high-frequency timing jitter (integration bandwidth of 17.5 kHz - 10 MHz, where the measurement instrument-…
Conditional correlation in asset return and GARCH intensity model
Geon Ho Choe, Kyungsub Lee
In an asset return series there is a conditional asymmetric dependence between current return and past volatility depending on the current return's sign. To take into account the c…
High moment variations and their application
Geon Ho Choe, Kyungsub Lee
We propose a new method of measuring the third and fourth moments of return distribution based on quadratic variation method when the return process is assumed to have zero drift.…
Recursive formula for arithmetic Asian option prices
Kyungsub Lee
We derive a recursive formula for arithmetic Asian option prices with finite observation times in semimartingale models. The method is based on the relationship between the risk-ne…
Light Non-degenerate Composite Partners at the LHC
Cédric Delaunay, Thomas Flacke, J. Gonzalez-Fraile +3
We study the implications of a large degree of compositeness for the light generation quarks in composite pseudo-Nambu-Goldstone-boson Higgs models. We focus in particular on viabl…
On the Number of Edges of Fan-Crossing Free Graphs
Otfried Cheong, Sariel Har-Peled, Heuna Kim +1
A graph drawn in the plane with n vertices is k-fan-crossing free for k > 1 if there are no k+1 edges , such that have a common endpoint and cros…
The Gaussian-Smoothed Wigner Function and Its Application to Precision Analysis
Hai-Woong Lee
We study a class of phase-space distribution functions that is generated from a Gaussian convolution of the Wigner distribution function. This class of functions represents the joi…
Study of the 125 GeV Standard Model Higgs Boson Partial Widths and Branching Fractions
Leandro G. Almeida, Seung J. Lee, Stefan Pokorski +1
The discovery of the Higgs boson, with mass known to better than the percent level, enables for the first time precision Higgs boson analyses. Toward this goal, we define an expans…
Cylinders in singular del Pezzo surfaces
Ivan Cheltsov, Jihun Park, Joonyeong Won
For each del Pezzo surface with du Val singularities, we determine whether it admits a -polar cylinder or not. If it allows one, then we present an effective $\mathbb{Q…
Excluded vertex-minors for graphs of linear rank-width at most k
Jisu Jeong, O-joung Kwon, Sang-il Oum
Linear rank-width is a graph width parameter, which is a variation of rank-width by restricting its tree to a caterpillar. As a corollary of known theorems, for each , there is…
Beamforming Design for Joint Localization and Data Transmission in Distributed Antenna System
Seongah Jeong, Osvaldo Simeone, Alexander Haimovich +1
A distributed antenna system is studied whose goal is to provide data communication and positioning functionalities to Mobile Stations (MSs). Each MS receives data from a number of…
Faster Algorithms For Vertex Partitioning Problems Parameterized by Clique-width
Sang-il Oum, Sigve Hortemo Sæther, Martin Vatshelle
Many NP-hard problems, such as Dominating Set, are FPT parameterized by clique-width. For graphs of clique-width given with a -expression, Dominating Set can be solved in $4…
