Synthesis and antiviral bioactivity of chiral thioureas ...

A series of novel chiral thioureas 3a-n bearing leucine and phosphonate moieties were synthesized in excellent yields. The structures of the compounds were completely characterized by elemental analysis, IR, 1H-, 13C-, 31P- and 19F-NMR spectral data. A half-leaf method was used to determine the in v …

The amplified spontaneous emission in EDF with small pulse pump

The amplified Spontaneous Emission (ASE) is the important noise source for EDFA, affecting the EDFA based fiber laser seriously. The theory and practice have shown that the ASE is closely related with pump methods, so the study on the ASE of EDF under the condition of the pulse pumping has important academic significations.

Experimental investigation of the influence of laser ...

Using spontaneous parametric down conversion, polarization post selection and coincidence counting technique, the polarization Einstein-Podolsky-Rosen (EPR) entangled states are prepared. Experimental studies on the efficiency, contrast and fidelity with different pump laser intensities are performed systematically. The results show that the pump laser intensity distinctly influences the ...

Steering population transfer of a five-level polar NaK ...

The pump laser (or both the pump and Stokes laser) frequency are to be swept in such a way that the frequency difference sweeping allows molecular anharmonicities of the final states to be matched.

Monolithic integration of nanorod arrays on microfluidic ...

The capillary pump consists of small parallel microchannels, which determine the main capillary pressure on the liquid and therefore define the average flow rate.

Recurrent de novo single point mutation on the gene encoding ...

The etiology of epilepsy remains undefined in two-thirds of patients. Here, we identified a de novo mutation of ATP1A2 (c.2426 T>G, p.Leu809Arg), which encodes the α2 subunit of Na+/K+-ATPase, from a family with idiopathic epilepsy. This mutation caused seizures in the study patients. We generated the point mutation mouse model Atp1a2L809R , which recapitulated the epilepsy observed in the ...
