An auto-B?cklund transformation for the quad equation Q1_(1) is considered as a discrete equation,called h2^(a),which is a so called torqued version of *** equations h2^(a) and Q1_(1) compose a consistent cube,from which an auto-B?cklund transformation and a Lax pair for h2^(a) are *** generally it is shown that auto-B?cklund transformations admit auto-Backlund *** the auto-Backlund transformation for h2^(a)we derive a seed solution and a one-soliton *** this solution it is seen that h2^(a) is a semi-autonomous lattice equation,as the spacing parameter q depends on m but it disappears from the plane wave factor.

一、前言正反反复选择(RRS)程序首先由Comstock等(1949)为植物特殊配合力育种而提出。后由Bell等(1950)伸展到动物育种中。此后试验的主要目的是确定RRS对杂种性能和纯系选择(PLS)及对纯种性能选择的有效性。在当前,几乎所有商品育种畜都经受了PLS的高度选择,表明杂交育种对开发非加性变异是重要的。Legetes(1988)指出,杂种优势的利用已成为应用育种纲要的一个主要部分。在现代育种体系中,为了提高杂交性能,多采用RRS及其改进的RRS方法。本综述将从理论和实践上集中于RRS和PLS两体系的比较,并讨论各自的长处和改进的可能性。

A curved image sensor on plastic foil has been developed for cone beam computed tomography(CBCT)X-ray *** image sensor of about 6×8 cm^(2) size has been built on a thin polyimide foil with an indium gallium zinc oxide(IGZO)backplane and an organic photodetectors(OPD)frontplane.A flexible cesium iodide(CsI)scintillator has been attached to the optical sensor with 480×640 pixels of 126µm *** current density of the OPD was low with less than 10^(−7) mA/cm^(2) at−2 V,while an external quantum efficiency(EQE)of about 50%was reached in the visible wavelength range matched to the scintillator *** image quality of the digital X-ray detector allowed for 3D reconstruction images of a bone phantom on a rotating stage with a lab *** curved detector with 32 cm curvature radius opens up the path for very compact CBCT gantries with largely reduced footprint.

We report a comprehensive Raman scattering study on layered mPS_3(m = mn, Fe, Ni), a two-dimensional magnetic compound with weak van der Waals interlayer coupling. The observed Raman phonon modes have been well assigned by the combination of first-principles calculations and the polarization-resolved spectra. Careful symmetry analysis on the angle-dependent spectra demonstrates that the crystal symmetry is strictly described by C_(2h)but can be simplified to D_(3d) with good accuracy. Interestingly, the three compounds share exactly the same lattice structure but show distinct magnetic structures. This provides us with a unique opportunity to study the effect of different magnetic orders on lattice dynamics in mPS_3. Our results reveal that the in-plane Nel antiferromagnetic(AF) order in mnPS_3 favors a spin–phonon coupling compared to the in-plane zig-zag AF in NiPS_3 and FePS_3. We have discussed the mechanism in terms of the folding of magnetic Brillouin zones. Our results provide insights into the relation between lattice dynamics and magnetism in the layered mPX_3(m = transition metal, X = S, Se) family and shed light on the magnetism of monolayer mPX_3 materials.
