Exceptionally large second-order nonlinear optical response in donor-graphene nanoribbon-acceptor systems.

Chemistry (Weinheim an der Bergstrasse, Germany)

Zhou ZJ, Li XP, Ma F, Liu ZB, Li ZR, Huang XR, Sun CC.
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))...

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

IEEE transactions on pattern analysis and machine intelligence

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...

BACKGROUND: Depside salts from Salvia miltiorrhiza, with active components of lithospermic acid B (LSB), rosmarinic acid (RA), and lithospermic acid (LA), are a multicomponent drug marketed in China for the treatment of coronary heart disease.OBJECTIVES: The aims of this...

Pd-catalyzed allylic alkylation of dienyl carbonates with nitromethane with high C-5 regioselectivity.

Chemical communications (Cambridge, England)

Yang XF, Li XH, Ding CH, Xu CF, Dai LX, Hou XL.
PMID: 24266021
Chem Commun (Camb). 2014 Jan 14;50(4):484-6. doi: 10.1039/c3cc46574h.

A highly regioselective palladium-catalyzed allylic alkylation of dienyl esters with nitromethane has been developed, providing selective access to the C-5 attacked products. The structures of the ligands as well as the steric effect of the substrates are important factors...

PMID: 26199610
Neural Regen Res. 2015 Jun;10(6):932-7. doi: 10.4103/1673-5374.158353.

The present study aimed to explore the mechanism underlying the protective effects of hydrogen sulfide against neuronal damage caused by cerebral ischemia/reperfusion. We established the middle cerebral artery occlusion model in rats via the suture method. Ten minutes after...

Online Metric-Weighted Linear Representations for Robust Visual Tracking.

IEEE transactions on pattern analysis and machine intelligence

Li X, Shen C, Dick A, Zhang ZM, Zhuang Y.
PMID: 26390446
IEEE Trans Pattern Anal Mach Intell. 2016 May;38(5):931-50. doi: 10.1109/TPAMI.2015.2469276. Epub 2015 Aug 17.

In this paper, we propose a visual tracker based on a metric-weighted linear representation of appearance. In order to capture the interdependence of different feature dimensions, we develop two online distance metric learning methods using proximity comparison information and...
