PMID: 21319235
Chemistry. 2011 Feb 18;17(8):2414-9. doi: 10.1002/chem.201001727. Epub 2011 Jan 07.

Graphene nanoribbon (GNR) has been used, for the first time, as an excellent conjugated bridge in a donor-conjugated bridge-acceptor (D-B-A) framework to design high-performance second-order nonlinear optical materials. Owing to the unique diradical planar conjugated bridge of GNR, D(NH(2))-GNR-A(NO(2))...

Morphology of nematic and smectic vesicles.

Proceedings of the National Academy of Sciences of the United States of America

Xing X, Shin H, Bowick MJ, Yao Z, Jia L, Li MH.
PMID: 22431595
Proc Natl Acad Sci U S A. 2012 Apr 03;109(14):5202-6. doi: 10.1073/pnas.1115684109. Epub 2012 Mar 19.

Recent experiments on vesicles formed from block copolymers with liquid-crystalline side chains reveal a rich variety of vesicle morphologies. The additional internal order ("structure") developed by these self-assembled block copolymer vesicles can lead to significantly deformed vesicles as a...

An incremental DPMM-based method for trajectory clustering, modeling, and retrieval.

IEEE transactions on pattern analysis and machine intelligence

Hu W, Li X, Tian G, Maybank S, Zhang Z.
PMID: 23520251
IEEE Trans Pattern Anal Mach Intell. 2013 May;35(5):1051-65. doi: 10.1109/TPAMI.2012.188.

Trajectory analysis is the basis for many applications, such as indexing of motion events in videos, activity recognition, and surveillance. In this paper, the Dirichlet process mixture model (DPMM) is applied to trajectory clustering, modeling, and retrieval. We propose...

Structures of Pb(n) (n = 21-30) clusters from first-principles calculations.

Journal of physics. Condensed matter : an Institute of Physics journal

Li XP, Lu WC, Wang CZ, Ho KM.
PMID: 21403370
J Phys Condens Matter. 2010 Nov 24;22(46):465501. doi: 10.1088/0953-8984/22/46/465501. Epub 2010 Oct 29.

Neutral lead clusters Pb(n) (n = 21-30) were studied using a genetic algorithm (GA)/tight-binding (TB) search combined with density functional theory (DFT)-Perdew-Burke-Ernzerhof (PBE) calculations. The calculated results show that the Pb(n) (22 ≤ n ≤ 30) clusters favor endohedral...

Quantitative imaging in medicine and surgery

Huang H, Le XH, Zhou BP, Lu PX.
PMID: 25202665
Quant Imaging Med Surg. 2014 Aug;4(4):291-3. doi: 10.3978/j.issn.2223-4292.2014.04.13.

Hepatic angiosarcoma, also called Kupffer's sarcoma, is a malignant mesenchymal neoplasm of endothelial cells, represents less than two percent of all primary liver neoplasm. Hepatic angiosarcoma is an infrequent and difficult-to-diagnose disease, mostly discovered by chance. Because of its...
