Fronthaul Compression and Precoding Design for C-RANs over Ergodic Fading Channel
Jinkyu Kang, Osvaldo Simeone, Joonhyuk Kang +1
This work investigates the joint design of fronthaul compression and precoding for the downlink of Cloud Radio Access Networks (C-RANs). In a C-RAN, a central unit (CU) performs th…
Quantum knots and the number of knot mosaics
Seungsang Oh, Kyungpyo Hong, Ho Lee +1
Lomonaco and Kauffman developed a knot mosaic system to introduce a precise and workable definition of a quantum knot system. This definition is intended to represent an actual phy…
Immersed Finite Element Method for Eigenvalue Problem
Seungwoo Lee, Do Y. Kwak, Imbo Sim
We consider the approximation of elliptic eigenvalue problem with an immersed interface. The main aim of this paper is to prove the stability and convergence of an immersed finite…
The asymmetry and the diurnal variation in axionic dark matter searches
Y. Semertzidis, J. D. Vergados
In the present work we study possible time dependent effects in Axion Dark Matter searches employing resonant cavities. We find that the width of the resonance, which depends on th…
Max-Product Belief Propagation for Linear Programming: Applications to Combinatorial Optimization
Sejun Park, Jinwoo Shin
The max-product {belief propagation} (BP) is a popular message-passing heuristic for approximating a maximum-a-posteriori (MAP) assignment in a joint distribution represented by a…
Characterization of timing jitter spectra in free-running mode-locked lasers with 340 dB dynamic range over 10 decades of Fourier frequency
Kwangyun Jung, Jungwon Kim
We demonstrate a method that enables accurate timing jitter spectral density characterization of free-running mode-locked laser oscillators over more than 10-decade of Fourier freq…
Two-Stage Beamformer Design for Massive MIMO Downlink By Trace Quotient Formulation
Donggun Kim, Gilwon Lee, Youngchul Sung
In this paper, the problem of outer beamformer design based only on channel statistic information is considered for two-stage beamforming for multi-user massive MIMO downlink, and…
Redundant blow-ups of rational surfaces with big anticanonical divisor
DongSeon Hwang, Jinhyung Park
We completely classify redundant blow-ups appearing in the theory of rational surfaces with big anticanonical divisor due to Sakai. In particular, we construct a rational surface w…
Recent progress in atomistic simulation of electrical current DNA sequencing
Han Seul Kim, Yong-Hoon Kim
We review recent advances in the DNA sequencing based on the measurement of transverse electrical currents. Device configurations proposed in the literature are classified accordin…
Genuine non-congruence subgroups of Drinfeld modular groups
A. W. Mason, Andreas Schweizer
Let be the ring of elements in an algebraic function field over a finite field which are integral outside a fixed place . In an earlier paper we have shown th…
On laminar groups, Tits alternatives, and convergence group actions on
Juan Alonso, Hyungryul Baik, Eric Samperton
Following previous work of the second author, we establish more properties of groups of circle homeomorphisms which admit invariant laminations. In this paper, we focus on a certai…
A non-iterative method for the electrical impedance tomography based on joint sparse recovery
Ok Kyun Lee, Hyeonbae Kang, Jong Chul Ye +1
The purpose of this paper is to propose a non-iterative method for the inverse conductivity problem of recovering multiple small anomalies from the boundary measurements. When smal…
Detecting solar chameleons through radiation pressure
S. Baum, G. Cantatore, D. H. H. Hoffmann +4
Light scalar fields can drive the accelerated expansion of the universe. Hence, they are obvious dark energy candidates. To make such models compatible with tests of General Relati…
Training Beam Sequence Design for Millimeter-Wave MIMO Systems: A POMDP Framework

In this paper, adaptive training beam sequence design for efficient channel estimation in large millimeter-wave(mmWave) multiple-input multiple-output (MIMO) channels is considered…
Atomistic Mechanisms of Codoping-Induced p- to n-Type Conversion in Nitrogen-Doped Graphene
Hyo Seok Kim, Han Seul Kim, Seong Sik Kim +1
It was recently shown that nitrogen-doped graphene (NG) can exhibit both p- and n-type characters depending on the C-N bonding nature, which represents a significant bottleneck for…
Stability of hypersurface sections of quadric threefolds
Sangho Byun, Yongnam Lee
Let be a complete intersection of a smooth quadric 3-fold and a hypersurface of degree in . In this paper we analyze GIT stability of with respect to…
Normal versus anomalous self-diffusion in two-dimensional fluids: Memory function approach and generalized asymptotic Einstein relation
Hyun Kyung Shin, Bongsik Choi, Peter Talkner +1
Based on the generalized Langevin equation for the momentum of a Brownian particle a generalized asymptotic Einstein relation is derived. It agrees with the well-known Einstein rel…
Boosted Event Topologies from TeV Scale Light Quark Composite Partners
Mihailo Backović, Thomas Flacke, Jeong Han Kim +1
We propose a new search strategy for quark partners which decay into a boosted Higgs and a light quark. As an example, we consider phenomenologically viable right handed up-type qu…
