Wild soybean is a typical short-day plant that begins flowering when the days are shorter than its critical photoperiod, Soybean was domesticated in the temperate region of East Asia at the relatively high latitude, and the breeding and release of soybean varieties have historically centered on mid- and high-latitude temperate regions. Low-latitude areas with tropical and sub- tropical climates were previously considered unsuitable for soy- bean production because most temperate soybean varieties ex- hibited precocious flowering and early maturity and suffered from low yields.

磁斯格明子是一种拓扑自旋结构,凭借其尺寸小、结构稳定和驱动电流密度低等特性,有望成为新一代赛道磁存储器件的信息存储单元。在存有磁斯格明子的材料体系中,具有界面Dzyaloshinskii-Moriya Interaction(DMI)的铁磁多层膜可与现代纳米制造工艺兼容,并且这种铁磁多层膜产生的磁斯格明子在室温下可稳定存在,这为基于磁斯格明子研发的电子器件提供了材料基础。然而磁性多层膜中界面DM相互作用、交换相互作用和偶极相互作用等各种作用之间的竞争,导致了磁斯格明子密度的随机变化,降低了磁斯格明子器件的可控性。因此,系统的研究材料参数对磁斯格明子密度的调控具有重要的意义。本文通过改变磁性层Co层的厚度调控了磁性多层膜中磁斯格明子的密度。实验结果表明,随着Co层厚度的增加,磁斯格明子的密度先增加后减少,其中Co层为2.1 nm时磁斯格明子密度最大。理论计算表明,磁性层厚度的变化会引起磁各向异性的转变和内禀属性DM相互作用的改变,进而影响磁斯格明子密度的变化。

Assessing spatial variability and mapping of soil properties constitute important prerequisites for soil and crop management in agricultural areas. To explore the relationship between soil spatial variability and land management, 256 samples were randomly collected at two depths (surface layer 0–20 cm and subsurface layer 20–40 cm) under different land use types and soil parent materials in Yujiang County, jiangxi Province, a red soil region of China. The pH, soil organic matter (SOM), total nitrogen (TN), cation exchange capacity (CEC), and base saturation (BS) of the soil samples were examined and mapped. The results indicated that soils in Yujiang were acidified, with an average pH of 4.87 (4.03–6.46) in the surface layer and 4.99 (4.03–6.24) in the subsurface layer. SOM and TN were significantly higher in the surface layer (27.6 and 1.50 g kg–1, respectively) than in the subsurface layer (12.1 and 0.70 g kg–1, respectively), while both CEC and BS were low (9.0 and 8.0 cmol kg–1, 29 and 38% for surface and subsurface layers, respectively). Paddy soil had higher pH (mean 4.99) than upland and forest soils, while soil derived from river alluvial deposits (RAD) had higher pH (mean 5.05) than the other three parent materials in both layers. Geostatistical analysis revealed that the best fit models were exponential for pH and TN, and spherical for BS in both layers, while spherical and Gaussian were the best fitted for SOM and CEC in the surface and subsurface layers. Spatial dependency varied from weak to strong for the different soil properties in both soil layers. The maps produced by selecting the best predictive variables showed that SOM, TN, and CEC had moderate levels in most parts of the study area. This study highlights the importance of site-specific agricultural management and suggests guidelines for appropriate land management decisions.

We have studied the luminosity-timescales relation 0f29 γ-ray-loud blazars with observed minimum variation timescales. Following the acceleration model of Ghisellini and Maraschi (1989 Astrophys. J. 340 189), a relation between the variation of the timescale in γ-rays and that in other wavebands has been derived. Both the observed and Doppler-corrected γ-ray luminosity-time scales relations have been calculated. The observed luminosity of the majority of sources is above the Eddington limit. The intrinsic luminosity of all sources is below the Eddington limit, suggesting that the γ-ray emission of the γ-ray-loud blazar originates from relativistic jets.

Basic magnesium carbonate(4 MgCO3·Mg(OH)2·4 H2 O) with spherical-like structure was synthesized through precursors thermal decomposition. The precursor of magnesium carbonate trihydrates(MgCO3·3 H2 O) was synthesized by brine and ammonium bicarbonate, and the thermal decomposition conditions were investigated in detail. The obtained particulate was characterized using SEM, XRD and laser particle analyzer. The result showed that it was easy to obtain spherical-like 4 MgCO3·Mg(OH)2·4 H2 O by precursor thermal decomposition at 80~100 ℃ with thermal decomposition time 90 min, stirring time 15 min and the liquid initial concentration 0.1 mol/L, while rod-like 4 MgCO3·Mg(OH)2·4 H2 O with a surface of "house of card" structure was more likely to be obtained at low temperature(55 ℃), and rosette-like products were obtained at a little higher temperature(80 ℃) by direct synthesis.
