Metal halide perovskites possess intriguing optoelectronic properties,however,the lack of precise control of on-chip fabrication of the large-scale perovskite single crystal arrays restricts its application in integrated ***,we report a space confinement and antisolvent-assisted crystallization method for the homogeneous perovskite single crystal arrays spanning 100 square centimeter *** method enables precise control over the crystal arrays,including different array shapes and resolutions with less than 10%-pixel position variation,tunable pixel dimensions from 2 to 8 pm as well as the in-plane rotation of each *** crystal pixel could serve as a high-quality whispering gallery mode(WGM)microcavity with a quality factor of 2915 and a threshold of 4.14μJ cm^(-2).Through directly on-chip fabrication on the patterned electrodes,a vertical structured photodetector array is demonstrated with stable photoswitching behavior and the capability to image the input patterns,indicating the potential application in the integrated systems of this method.

It has been long established that the terrestrial vegetation in spring has stronger photosynthetic capability than in ***,this study challenges this consensus by comparing photosynthetic capability of terrestrial vegetation between the spring and autumn seasons based on measurements of 100 in situ eddy covariance towers over global extratropical *** the majority of these sites,photosynthetic capability,indicated by light use efficiency(LUE)and apparent quantum efficiency,is significantly higher in autumn than in spring,due to lower atmosphere vapor pressure deficit(VPD)at the same air *** VPD differences also substantially explain the interannual variability of the differences in photosynthetic capability between spring and *** further reveal that VPD in autumn is significantly lower than in spring over 74.14% of extratropical areas,based on a global climate *** contrast,LUE derived from a data-driven vegetation production dataset is significantly higher in autumn in over 61.02% of extratropical vegetated *** Earth system models consistently projected continuous larger VPD values in spring compared with autumn,which implies that the impacts on vegetation growth will long exist and should be adequately considered when assessing the seasonal responses of terrestrial ecosystems to future climate conditions.

Presently,integrating multi-omics information into a prediction model has become a ameliorate strategy for genomic selection to improve genomic prediction ***,we set the genomic and transcriptomic data as the training population data,using BSLMM,TWAS,and eQTL mapping to prescreen features according to |β_(b)|>0,top 1%of phenotypic variation explained(PVE),expression-associated single nucleotide polymorphisms(eSNPs),and egenes(false discovery rate(FDR)<0.01),where these loci were set as extra fixed effects(named GBLUP-Fix)and random effects(GFBLUP)to improve the prediction accuracy in the validation population,*** results suggested that both GBLUP-Fix and GFBLUP models could improve the accuracy of longissimus dorsi muscle(LDM),water holding capacity(WHC),shear force(SF),and pH in Huaxi cattle on average from 2.14 to 8.69%,especially the improvement of GFBLUP-TWAS over GBLUP was 13.66%for *** methods also captured more genetic variance than *** study confirmed that multi-omics-assisted large-effects loci prescreening could improve the accuracyofgenomic prediction.

现有小电流接地故障选线方法均以辐射状线路为基础,特定情况时将出现同母线环路供电情况,接地故障特征将发生变化,已有选线方法需要重新审视。文中建立了含环路配电网单相接地故障复合网络,推导了环路两端出口稳态与暂态零序电流的分布特征,分析了已有选线方法的适应性。结果表明,环路接地时,随线路参数和故障位置不同,环路两端出口电气量并非始终表现为故障线路特征,已有稳态量和暂态量选线方法将可能出现误选与漏选。可通过增加备选线路条数并利用环路中一条出口线路切除前后其余各线路零序导纳的变化辨识故障线路或将环路两端出口零序电流之和参与选线比较的方法解决该问题。仿真与现场数据验证了故障特征的正确性及所提选线措施的有效性。

利用高光谱成像技术实现对红提总酸和硬度无损检测和分布可视化。首先,利用高光谱采集生长期360个红提样本在波段450~1000 nm的高光谱图像信息后用化学方法测定对应样本的总酸,用质构仪测定硬度。采用KS(Kennard-Stone)算法将总样本按照3∶1的比例划分为训练集(270个样本)和测试集(90个样本)。对红提原始光谱数据分别利用标准正态变量变换(standard normal variate transformation,SNV)、卷积平滑(Savitzky-Golay,SG)处理法、多元散射校正(multivariate scatter correction,MSC)、归一化等光谱预处理方法处理,确定最优光谱预处理方法。然后,分别采用一次降维(竞争性自适应重加权算法(competitive adaptive reweighted sampling,CARS)、连续投影算法(successive projections algorithm,SPA)、遗传算法(genetic algorithm,GA)、无信息变量消除法(uninformative variable elimination,UVE))算法和组合降维算法(CARS-SPA、UVE-SPA)6种降维方法对光谱信息进行特征变量提取;分别建立红提总酸和硬度的偏最小二乘回归(partial least square regression,PLSR)最优预测模型。最后,根据所建最优预测模型计算红提图像每个像素点的总酸和硬度,得到灰度图像并对该灰度图像进行伪彩色变换,实现红提总酸和硬度的分布可视化。结果表明根据提取到的特征波长对生长期内的红提总酸和硬度进行建模分析得到:总酸的最优检测模型为MSC-CARS-SPA-PLSR,其预测集相关系数Rp和均方根误差分别为0.9851、1.3482,残差预测偏差(residual predictive deviation,RPD)为5.6643;硬度的最优检测模型为SG-CARSPLSR,其预测集相关系数Rp和均方根误差分别为0.9291、7.9354,RPD为2.5108。综上利用高光谱成像技术可以实现红提总酸和硬度的检测与可视化分布,为生长期红提总酸和硬度的检测及可视化找到一种新方法。
