The Shaping of the Multipolar Pre-Planetary Nebula CRL 618 by Multi-directional BulletsMar 01 2016In order to understand the formation of the multipolar structures of the pre-planetary nebula (PPN) CRL 618, we perform 3D simulations using a multi-directional bullet model. The optical lobes of CRL 618 and fast molecular outflows at the tips of the ... More

Towards Realistic Face Photo-Sketch Synthesis via Composition-Aided GANsDec 04 2017Dec 21 2018Face photo-sketch synthesis aims at generating a facial sketch/photo conditioned on a given photo/sketch. It is of wide applications including digital entertainment and law enforcement. Precisely depicting face photos/sketches remains challenging due ... More

Higgs-like Excitations of Cold Atom System with Spin-orbit CouplingJul 16 2012Jul 30 2013The Higgs-like excitations, which distinguish from the Higgs amplitude mode in many-body system, are single-particle excitations in system with non-Abelian gauge potential. We investigate the Higgs-like excitations of cold atom system in artificial non-Abelian ... More
