Aberrant Brain Regional Homogeneity and Functional Connectivity in Middle-Aged T2DM Patients: A Resting-State Functional MRI Study.

Frontiers in human neuroscience

Liu D, Duan S, Zhang J, Zhou C, Liang M, Yin X, Wei P, Wang J.
PMID: 27729856
Front Hum Neurosci. 2016 Sep 27;10:490. doi: 10.3389/fnhum.2016.00490. eCollection 2016.

Type 2 diabetes mellitus (T2DM) has been associated with cognitive impairment. However, its neurological mechanism remains elusive. Combining regional homogeneity (ReHo) and functional connectivity (FC) analyses, the present study aimed to investigate brain functional alterations in middle-aged T2DM patients,...

PMID: 29085512
Oncol Lett. 2017 Oct;14(4):4989-4994. doi: 10.3892/ol.2017.6824. Epub 2017 Aug 25.

Aberrant DNA methylation is associated with non-small cell lung cancer (NSCLC), suggesting that gene promoter methylation may be a potential biomarker for the detection or risk prediction of NSCLC. The present study aimed to evaluate the potential usage of...

Significant Contributions of the Albrecht's A Term to Nonresonant Raman Scattering Processes.

Journal of chemical theory and computation

Gong ZY, Tian G, Duan S, Luo Y.

The Raman intensity can be well described by the famous Albrecht's Raman theory that consists of A and B terms. It is well-known that the contribution from Albrecht's A term can be neglected without any loss of accuracy for...

Diffusion-Controlled Rotation of Triptycene in a Metal-Organic Framework (MOF) Sheds Light on the Viscosity of MOF-Confined Solvent.

ACS central science

PMID: 27725958
ACS Cent Sci. 2016 Sep 28;2(9):608-613. doi: 10.1021/acscentsci.6b00168. Epub 2016 Aug 23.

Artificial molecular machines are expected to operate under conditions of very low Reynolds numbers with inertial forces orders of magnitude smaller than viscous forces. While these conditions are relatively well understood in bulk fluids, opportunities to assess the role...

Lighting up long-range charge-transfer states by a localized plasmonic field.

Nanoscale

Xie Z, Duan S, Wang CK, Luo Y.
PMID: 29149233
Nanoscale. 2017 Nov 30;9(46):18189-18193. doi: 10.1039/c7nr06322a.

The long-range charge-transfer states in a donor-acceptor system exhibit well separated electron-hole pairs, but are often difficult to achieve by optical means owing to a very small overlap between the wave functions of the donor and acceptor. We have...

Visualization of Vibrational Modes in Real Space by Tip-Enhanced Non-Resonant Raman Spectroscopy.

Angewandte Chemie (International ed. in English)

Duan S, Tian G, Luo Y.
PMID: 26563759
Angew Chem Int Ed Engl. 2016 Jan 18;55(3):1041-5. doi: 10.1002/anie.201508218. Epub 2015 Nov 13.

We present a general theory to model the spatially resolved non-resonant Raman images of molecules. It is predicted that the vibrational motions of different Raman modes can be fully visualized in real space by tip-enhanced non-resonant Raman scattering. As...

Route searching based on neural networks and heuristic reinforcement learning.

Cognitive neurodynamics

Zhang F, Duan S, Wang L.
PMID: 28559954
Cogn Neurodyn. 2017 Jun;11(3):245-258. doi: 10.1007/s11571-017-9423-7. Epub 2017 Feb 09.

In this paper, an improved and much stronger RNH-QL method based on RBF network and heuristic Q-learning was put forward for route searching in a larger state space. Firstly, it solves the problem of inefficiency of reinforcement learning if...

Controllable two-scale network architecture and enhanced mechanical properties of (Ti5Si3+TiBw)/Ti6Al4V composites.

Scientific reports

Jiao Y, Huang LJ, Duan TB, Wei SL, Kaveendran B, Geng L.
PMID: 27622992
Sci Rep. 2016 Sep 13;6:32991. doi: 10.1038/srep32991.

Novel Ti6Al4V alloy matrix composites with a controllable two-scale network architecture were successfully fabricated by reaction hot pressing (RHP). TiB whiskers (TiBw) were in-situ synthesized around the Ti6Al4V matrix particles, and formed the first-scale network structure (FSNS). Ti5Si3 needles...
