Stable radio frequency dissemination by simple hybrid frequency modulation scheme.

Optics letters

Opt Lett. 2014 Sep 15;39(18):5255-8. doi: 10.1364/OL.39.005255.

In this Letter, we propose a fiber-based stable radio frequency transfer system by a hybrid frequency modulation scheme. Creatively, two radio frequency signals are combined and simultaneously transferred by only one laser diode. One frequency component is used to...

Doping-dependent photon scattering resonance in the model high-temperature superconductor HgBa2CuO4+δ revealed by Raman scattering and optical ellipsometry.

Physical review letters

The present study aimed to investigate the effect of laser therapy on the expression of vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) in the plasma of infants diagnosed with cutaneous hemangioma, in order to identify...

Organocatalytic Enantioselective Protonation for Photoreduction of Activated Ketones and Ketimines Induced by Visible Light.

Angewandte Chemie (International ed. in English)

Lin L, Bai X, Ye X, Zhao X, Tan CH, Jiang Z.
PMID: 28925022

The first catalytic asymmetric photoreduction of 1,2-diketones and α-keto ketimines under visible light irradiation is reported. A transition-metal-free synergistic catalysis platform harnessing dicyanopyrazine-derived chromophore (DPZ) as the photoredox catalyst and a non-covalent chiral organocatalyst is effective for these transformations....

The wavevector substar group in reciprocal space and its representation.

PMID: 28862166
Acta Crystallogr A Found Adv. 2017 Sep 01;73:403-413. doi: 10.1107/S205327331700688X. Epub 2017 Aug 15.

A new concept of the wavevector substar group is established which, in the study of translational symmetry breaking of a crystal, only considers the particular arms of the wavevector star taking part in the phase transition; this is in...

Pressure induced superconductivity in the antiferromagnetic Dirac material BaMnBi.

Scientific reports

Chen H, Li L, Zhu Q, Yang J, Chen B, Mao Q, Du J, Wang H, Fang M.
PMID: 28487572
Sci Rep. 2017 May 09;7(1):1634. doi: 10.1038/s41598-017-01967-y.

The so-called Dirac materials such as graphene and topological insulators are a new class of matter different from conventional metals and (doped) semiconductors. Superconductivity induced by doing or applying pressure in these systems may be unconventional, or host mysterious...

Inhibition of endoplasmic reticulum stress is involved in the neuroprotective effect of aFGF in neonatal hypoxic-ischaemic brain injury.

Acidic fibroblast growth factor (aFGF) has been shown to exert neuroprotective effects in experimental models and human patients. In this study, we investigated whether aFGF intranasal-treatment protected against neonatal hypoxic-ischaemic brain injury and evaluated the role of endoplasmic reticulum...
