Estimates for lower bounds of eigenvalues of the poly-Laplacian and quadratic polynomial operator of the LaplacianDec 13 2011In this paper, we investigate the Dirchlet eigenvalue problems of poly-Laplacian with any order and quadratic polynomial operator of the Laplacian. We give some estimates for lower bounds of the sums of their first $k$ eigenvalues which improve the previous ... More
A Collaborative Framework for In-network Video Caching in Mobile NetworksApr 03 2014Due to explosive growth of online video content in mobile wireless networks, in-network caching is becoming increasingly important to improve the end-user experience and reduce the Internet access cost for mobile network operators. However, caching is ... More
Fault Location in Power Distribution Systems via Deep Graph Convolutional NetworksDec 22 2018This paper develops a novel graph convolutional network (GCN) framework for fault location in power distribution networks. The proposed approach integrates multiple measurements at different buses while takes system topology into account. The effectiveness ... More
Possibility to study pentaquark states $P_{c}(4312), P_{c}(4440)$, and $P_{c}(4457)$ in $γp\rightarrow J/ψp$ reactionApr 26 2019May 31 2019Inspired by the observation of the pentaquark states $P_{c}(4312),P_{c}(4440)$ and $P_{c}(4457)$ at LHCb, photoproduction of these three $P_{c}$ states via the interaction $\gamma p\rightarrow J/\psi p$ is investigated in an effective Lagrangian approach. ...

Hidden-strange molecular states and the $Nφ$ bound state via a QCD van der Waals forceApr 25 2018Nov 14 2018In this work, we study the hidden-strange molecular states composed of a baryon and a vector meson in a coupled-channel $N\rho-N\omega-N\phi-\Lambda K^*-\Sigma K^*$ interaction. With the help of the effective Lagrangians which coupling constants are determined ... More
Exponential Moving Average Model in Parallel Speech Recognition TrainingMar 03 2017As training data rapid growth, large-scale parallel training with multi-GPUs cluster is widely applied in the neural network model learning currently.We present a new approach that applies exponential moving average method in large-scale parallel training ...

Testing Einstein's Equivalence Principle with Fast Radio BurstsDec 24 2015The accuracy of Einstein's Equivalence Principle (EEP) can be tested with the observed time delays between correlated particles or photons that are emitted from astronomical sources. Assuming as a lower limit that the time delays are caused mainly by ... More
Constraining the Evolution of the Baryon Fraction in the IGM with FRB and $H(z)$ dataJul 23 2019Extragalactic dispersion measures (DMs) obtained from observations of fast radio bursts (FRBs) are an excellent tool for probing intergalactic medium (IGM) and for conducting cosmography. However, the DM contribution from the IGM (${\rm DM_{IGM}}$) depends ... More
Electroweak properties of the $π$, $K$ and $K^*(892)$ in the three forms of relativistic kinematicsMar 31 2005The electromagnetic form factors, charge radii and decay constants of pion, K and K*(892) are calculated using the three forms of relativistic kinematics: instant form, point form and (light) front form. Simple representations of the mass operator together ... More
Investigation of two-color magneto-optical trap with cesium 6S1/2-6P3/2-7S1/2 ladder-type systemJan 12 2016A novel cesium (Cs) two-color magneto-optical trap (TC-MOT), which partially employs the optical radiation forces due to photon scattering of the 6P3/2 (F'=5) - 7S1/2 (F"=4) excited-state transition in the Cs 6S1/2 - 6P3/2 - 7S1/2 (852 + 1470 nm) ladder-type ...
