Recovering higher dimensional image data using multiplexed structured illumination.

Optics express

Dong S, Guo K, Jiang S, Zheng G.
PMID: 26698518
Opt Express. 2015 Nov 16;23(23):30393-8. doi: 10.1364/OE.23.030393.

Structured illumination (SI) using non-uniform intensity patterns is well-known for improving lateral resolution in microscopy. Here, we propose a multiplexed SI technique for recovering images with higher lateral resolution and with higher dimensional information at the same time. In...

The energy-level crossing behavior and quantum Fisher information in a quantum well with spin-orbit coupling.

Scientific reports

Wang ZH, Zheng Q, Wang X, Li Y.
PMID: 26931762
Sci Rep. 2016 Mar 02;6:22347. doi: 10.1038/srep22347.

We study the energy-level crossing behavior in a two-dimensional quantum well with the Rashba and Dresselhaus spin-orbit couplings (SOCs). By mapping the SOC Hamiltonian onto an anisotropic Rabi model, we obtain the approximate ground state and its quantum Fisher...

First-principles studies on the structural and spectral properties of C72 isomers and the chlorinated derivative C72Cl4.

PMID: 26922973
Phys Chem Chem Phys. 2016 Mar 21;18(11):8049-58. doi: 10.1039/c6cp00149a.

X-ray photoelectron (XPS) and near-edge X-ray absorption fine structure (NEXAFS) spectra, as well as the ground-state electronic/geometrical structures of two important isomers of the elusive C72 fullerene family (C2v- and D6d-symmetry, respectively) and the corresponding chlorinated derivative C72Cl4, which...

Magnetic anisotropy of iron-based metallic glassy fibers.

Chemical communications (Cambridge, England)

Liao W, Meng Y, Xu M, Zheng J, Gao S, Pan F.
PMID: 26390070
Chem Commun (Camb). 2015 Nov 18;51(89):16072-5. doi: 10.1039/c5cc05546f.

Flexible, uniform and surface smooth iron-based metallic glassy fibers (MGFs) were fabricated by a melt-extraction method. There was large magnetic anisotropy in the MGF. Our experimental results indicated that this large magnetic anisotropy was related to the unique magnetic...

Compositional grading within a mixture has a strong impact on the evaluation of the pre-exploitation distribution of hydrocarbons in underground layers and sediments. Thermodiffusion, which leads to a partial diffusive separation of species in a mixture due to the...

Machine Learning Estimation of Atom Condensed Fukui Functions.

Molecular informatics

Zhang Q, Zheng F, Zhao T, Qu X, Aires-de-Sousa J.
PMID: 27491791
Mol Inform. 2016 Feb;35(2):62-9. doi: 10.1002/minf.201500113. Epub 2015 Nov 24.

To enable the fast estimation of atom condensed Fukui functions, machine learning algorithms were trained with databases of DFT pre-calculated values for ca. 23,000 atoms in organic molecules. The problem was approached as the ranking of atom types with...

User roles and contributions during the new product development process in collaborative innovation communities.

Applied ergonomics

PMID: 28502399
Appl Ergon. 2017 Sep;63:106-114. doi: 10.1016/j.apergo.2017.04.013. Epub 2017 Apr 22.

Collaborative innovation (co-innovation) community emerges as a new product design platform where companies involve users in the new product development (NPD) process. Large numbers of users participate and contribute to the process voluntarily. This exploratory study investigates the heterogeneous...

Roles of Rap1 signaling in tumor cell migration and invasion.

Cancer biology & medicine

Zhang YL, Wang RC, Cheng K, Ring BZ, Su L.
PMID: 28443208
Cancer Biol Med. 2017 Feb;14(1):90-99. doi: 10.20892/j.issn.2095-3941.2016.0086.

Ras-associated protein-1 (Rap1), a small GTPase in the Ras-related protein family, is an important regulator of basic cellular functions (e.g., formation and control of cell adhesions and junctions), cellular migration, and polarization. Through its interaction with other proteins, Rap1...

A small-molecule material, 7,7-(4,4-bis(2-ethylhexyl)-4H-silolo[3,2-b:4,5-b']dithiophene-2,6-diyl)bis(6-fluoro-4-(5'-hexyl-[2,2'-bithiophen]-5-yl)benzo-[c] [1,2,5]thiadiazole) (p-DTS(FBTTH2)2), was used to modify the morphology and electron-transport properties of the polymer blend of poly(3-hexythiophene) (P3HT) and [6,6]-phenyl-C71-butyric acid methyl ester (PC71BM) bulk heterojunctions. As a result, a 24% increase in the power-conversion...
