Correlations of Interference and Link Successes in Heterogeneous Cellular NetworksNov 18 2014Nov 25 2014In heterogeneous cellular networks (HCNs), the interference received at a user is correlated over time slots since it comes from the same set of randomly located BSs. This results in the correlations of link successes, thus affecting network performance. ... More

Spin symmetry in Dirac negative energy spectrum in density-dependent relativistic Hartree-Fock theoryFeb 17 2010The spin symmetry in the Dirac negative energy spectrum and its origin are investigated for the first time within the density-dependent relativistic Hartree-Fock (DDRHF) theory. Taking the nucleus $^{16}$O as an example, the spin symmetry in the negative ... More

Heavy Quark Expansion in 1/\hat{m}_Q and |V_{cb}| ExtractionApr 30 2010The dressed heavy quark mass \hat{m}_Q=m_Q+\bar{{\Lambda}} with \bar{{\Lambda}} being the binding energy is introduced to characterize the heavy hadrons containing a single heavy quark. A heavy quark expansion in terms of the inverse of the dressed heavy ... More

Top quark pair production via polarized and unpolarized photons in Supersymmetric QCDApr 02 1997QCD corrections to top quark pair production via fusion of both polarized and unpolarized photons are calculated in Supersymmetric Model. The corrections are found to be sizable. The dependence of the corrections on the masses of the supersymmetric particles ... More

Charged Higgs boson pair production via gluon-gluon collisions in MSSM with CP violationDec 07 2000Dec 15 2000The CP-violating effects to the subprocess $gg\to H^+H^-$ is studied in the mSUGRA scenario at the CERN LHC, by taking into account the experimental bounds of electron and neutron EDM's. The CP violation effects in this process are related to the complex ... More

Magnetoelectric surface acoustic wave resonator with ultrahigh magnetic field sensitivityMay 16 2014May 19 2014A magnetoelectric surface acoustic wave (MESAW) type device based on piezoelectric/magnetostrictive heterostructure was proposed to use as weak magnetic field sensor. Unlike conventional magnetoelectric bulk laminates or film stacks collecting magnetic ... More

Supply-demand diagrams and a new framework for analyzing the inhomogeneous Lighthill-Whitham-Richards modelMay 25 2010Traditionally, the Lighthill-Whitham-Richards (LWR) models for homogeneous and inhomogeneous roads have been analyzed in flux-density space with the fundamental diagram of the flux-density relation. In this paper, we present a new framework for analyzing ... More
