The origin of the stabilized simple-cubic structure in Po
B. I. Min, J. H. Shim, Min Sik Park +3
The origin of the stabilized simple-cubic (SC) structure in Po is explored by using the first principle band calculations. We have found that the prime origin is the inherent stron…
QCD sum rules for the anti-charmed pentaquark
Yasemin Sarac, Hungchong Kim, Su Houng Lee
We present a QCD sum rule analysis for the anti-charmed pentaquark state with and without strangeness. While the sum rules for most of the currents are either non-convergent or dom…
A QCD sum rule study of the light scalar mesons
Hee-Jung Lee
We examine the interpretation of the light scalar meson nonet as bound states of the scalar diquark and the scalar antidiquark using the QCD sum rule approach. Our results are obta…
Directed polymers in random media under confining force
Hyeong-Chai Jeong
The scaling behavior of a directed polymer in a two-dimensional (2D) random potential under confining force is investigated. The energy of a polymer with configuration i…
Deformed Type 0A Matrix Model and Super-Liouville Theory for Fermionic Black Holes
Changrim Ahn, Chanju Kim, Jaemo Park +2
We consider a model in the fermionic black hole background. For this purpose we consider a model which contains both the N=1 and the N=2 super-Liouville interactions.…
Torque magnetometry studies of metamagnetic transitions in single-crystal HoNi_{2}B_{2}C and ErNi_{2}B_{2}C at T\approx 1.9 K
D. G. Naugle, B. I. Belevtsev, K. D. D. Rathnayaka +3
The metamagnetic transitions in single-crystal rare-earth nickel borocarbide HoNi_{2}B_{2}C and ErNi_{2}B_{2}C have been studied at 1.9 K with a Quantum Design torque magnetometer.…
Instability of defensive alliances in the predator-prey model on complex networks
Beom Jun Kim, Jianbin Liu, Jaegon Um +1
A model of six-species food web is studied in the viewpoint of spatial interaction structures. Each species has two predators and two preys, and it was previously known that the de…
Study of Strangeness Condensation by Expanding About the Fixed Point of the Harada-Yamawaki Vector Manifestation
G. E. Brown, C. -H. Lee, H. -J. Park +1
Building on, and extending, the result of a higher-order in-medium chiral perturbation theory combined with renormalization group arguments and a variety of observations of the vec…
D_s (2317) as a four-quark state in QCD sum rules
Hungchong Kim, Yongseok Oh
We perform a QCD sum rule study of the open-charmed as a four-quark state. Using the diquark-antidiquark picture for the four-quark state, we consider four possible in…

H. Kang, J. Jo, H. J. Kim +3
A variety of oscillations are observed in pancreatic islets.We establish a model, incorporating two oscillatory systems of different time scales: One is the well-known bursting mod…
Variational approach to nonlinear gravity-driven instabilities in a MHD setting
Hyung Ju Hwang
We establish a variational framework for nonlinear instabilities in a setting of the ideal magnetohydrodynamic (MHD) equations. We apply a variational method to various kind of smo…
Pattern formation (I): The Keller-Segel Model
Yan Guo, Hyung Ju Hwang
We investigate nonlinear dynamics near an unstable constant equilibrium in the classical Keller-Segel model. Given any general perturbation of magnitude , we prove that its nonl…
How Noise and Coupling Induce Bursting Action Potentials in Pancreatic beta-cells
J. Jo, H. Kang, M. Y. Choi +1
Unlike isolated beta-cells, which usually produce continuous spikes or fast and irregular bursts, electrically coupled beta-cells are apt to exhibit robust bursting action potentia…
