Soliton Solutions on Noncommutative Orbifold $ T^2/Z_4May 26 2003May 29 2003In this paper, we explicitly construct a series of projectors on integral noncommutative orbifold $T^2/Z_4$ by extended $GHS$ constrution. They include integration of two arbitary functions with $Z_4$ symmetry. Our expressions possess manifest $Z_{4}$ ... More
Algebraic Bethe ansatz for eight vertex model with general open-boundary conditionsApr 03 1996By using the intertwiner and face-vertex correpondence relation, we obtain the Bethe ansatz equation of eight vertex model with open boundary condtitions in the framework of algebraic Bethe ansatz method. The open boundary condition under consideration ... More
Topic Aware Neural Response GenerationJun 21 2016Sep 19 2016We consider incorporating topic information into the sequence-to-sequence framework to generate informative and interesting responses for chatbots. To this end, we propose a topic aware sequence-to-sequence (TA-Seq2Seq) model. The model utilizes topics ... More
Constraints on smoothness parameter and dark energy using observational $H(z)$ dataAug 11 2010The universe, with large-scale homogeneity, is locally inhomogeneous, clustering into stars, galaxies and larger structures. Such property is described by the smoothness parameter $\alpha$ which is defined as the proportion of matter in the form of intergalactic ... More
In Situ Electron Energy-Loss Spectroscopy in LiquidsDec 06 2012Jan 24 2013In situ scanning transmission electron microscopy (STEM) through liquids is a promising approach for exploring biological and materials processes. However, options for in situ chemical identification are limited: X-ray analysis is precluded because the ... More
Room temperature observation of electron resonant tunneling through InAs/AlAs quantum dotsDec 06 2007Molecular beam epitaxy is employed to manufacture self-assembled InAs/AlAs quantum-dot resonant tunneling diodes. Resonant tunneling current is superimposed on the thermal current, and they make up the total electron transport in devices. Steps in current-voltage ... More
Cheating-Resilient Incentive Scheme for Mobile Crowdsensing SystemsJan 08 2017Mobile Crowdsensing is a promising paradigm for ubiquitous sensing, which explores the tremendous data collected by mobile smart devices with prominent spatial-temporal coverage. As a fundamental property of Mobile Crowdsensing Systems, temporally recruited ... More
Z2 invariant protected bound states in topological insulatorsOct 04 2010Oct 08 2010We present an exact solution of a modifed Dirac equation for topological insulator in the presence of a hole or vacancy to demonstrate that vacancies may induce bound states in the band gap of topological insulators. They arise due to the Z_2 classification ... More
