为进一步发展节水农业,提高水分利用效率,建立作物产量与耗水量的响应关系,确定区域农业节水潜力,为水资源合理配置提供依据。以AquaCrop为研究模型,对模型产量模块参数标准化的水分生产效率(WP)和参考收获指数(HI0)进行多年率定与验证,以2.1.年作为现状水平年,通过设置4月1.日和4月2.日两个春小麦(‘新春6号’)播种日期,每个播种日期下设置400 mm、350 mm、300 mm、2.0 mm、2.0 mm的灌溉定额和7 d和1. d的灌溉周期,共2.个情景,对新疆阿勒泰地区春小麦产量进行模拟,对比不同情景下的春小麦产量和灌溉水利用效率受灌溉定额和灌水次数的影响,以产量和水分利用效率均较高为目标,择优选择最佳灌溉策略。利用现状年春小麦种植面积作为参考值,对比现状水平年和未来水平年在不同情景下的小麦产量及总节水量差异,分析小麦的节水潜力。结果表明:1.推荐WP=1. g∙m^(−2.和HI0=48%作为阿勒泰地区2.05—2.1.多年率定及2.1.—2.1.年验证后的产量模块参数,率定产量误差范围为−3.44%~5.67%,适用性评价指标均方根误差(RMSE)、相对均方根误差(RRMSE)、残差系数(CRM)、Willmott一致度(d)和纳什效率系数(ENS)值分别为0.1.0、0.02.、0.002.0.956、0.935,适用性好;2.1.—2.1.年验证产量误差分别为−0.41.、−3.02.、3.34%,模拟误差较小。2.不同情景下的模拟结果显示,情景S1.(4月2.日播种、灌溉定额为300 mm、灌溉周期为7 d)可以作为推荐灌溉策略,该模拟情景下,作物产量和灌溉水分利用效率分别为5.61. t∙hm^(−2.和1.870 kg∙m^(−3)。3)对于阿勒泰地区的春小麦种植,情景S1.作为推荐的灌溉策略,现状水平年可以实现节水2.335亿m^(3),节水潜力是可观的,未来水平年可以分别实现节水2.407亿m^(3)、2.431.m^(3)、2.476亿m^(3)。

目的:考察工作场所排斥对员工组织公民行为的负向影响,并探究物品线索在其中的调节作用。方法:研究1.1.8名职场人士进行问卷调查,研究2.过实验室研究探究物品线索在其中的调节作用,启动被排斥感后,被试被随机分为实验组和控制组分别观看奢侈品图片和无关图片,之后测量组织公民行为。结果:员工遭受的工作场所排斥水平越高,表现出的组织公民行为越少;当被排斥后,观看奢侈品图片能够显著提高个体的组织公民行为。结论:工作场所排斥对员工的组织公民行为有消极影响,物品线索能够调节工作场所排斥与组织公民行为的关系。

Detailed characterizations of genomic alterations have not identified subtype-specific vulnerabilities in adult gliomas. Mapping gliomas into developmental programs may uncover new vulnerabilities that are not strictly related to genomic alterations. After identifying conserved gene modules co-expressed with EGFR or PDGFRA (EM or PM), we recently proposed an EM/PM classification scheme for adult gliomas in a histological subtype- and grade-independent manner. By using cohorts of bulk samples, paired primary and recurrent samples, multi-region samples from the same glioma, single-cell RNA-seq samples, and clinical samples, we here demonstrate the temporal and spatial stability of the EM and PM subtypes. The EM and PM subtypes, which progress in a subtype-specific mode, are robustly maintained in paired longitudinal samples. Elevated activities of cell proliferation, genomic instability and microenvironment, rather than subtype switching, mark recurrent gliomas. Within individual gliomas, the EM/PM subtype was preserved across regions and single cells. Malignant cells in the EM and PM gliomas were correlated to neural stem cell and oligodendrocyte progenitor cell compartment, respectively. Thus, while genetic makeup may change during progression and/or within different tumor areas, adult gliomas evolve within a neurodevelopmental framework of the EM and PM molecular subtypes. The dysregulated developmental pathways embedded in these molecular subtypes may contain subtype-specific vulnerabilities.

课程改革是教育改革与发展的重要组成部分。国际课程改革的发展趋势与特点显示,当前世界各国注重促进学科融合,发展学生综合能力,以学生核心素养模型来推动和促进课程改革的发展成为重要方式。主要国家核心素养与课程体系相互关系呈现三种模式:核心素养独立于课程体系之外的美国模式,在课程体系中设置核心素养的芬兰模式以及通过课程标准内容设置体现核心素养的日本模式。基于此,构建基于核心素养的课程体系应至少包含具体化的教学目标、内容标准、教学建议和质量标准四部分;其中,具体化的教学目标和质量标准要体现学生核心素养;内容标准和教学建议要促进学生形成核心素养。

Background Resent advances on functional mapping have enabled us to conduct surgery on gliomas within the eloquent area. The objective of the article is to discuss the feasibility of a planned fractionated strategy of resection on low-grade gliomas （LGGs） involving Broca＇s area. We report the first surgical series of planned fractionated resections on LGGs within Broca＇s area, focusing on language functional reshaping. Methods Four patients were treated with fractionated operations for LGGs involving Broca＇s area. All cases underwent conventional magnetic resonance （MR） scanning, language functional MR and diffusion tensor imaging （DTI） before operation. The resections were then performed on patients under awake anesthesia using intraoperative electrical stimulation （IES） for functional mapping. Pre- and post-operative neuro-psychological examinations were evaluated.Results Total resections were achieved in all cases as confirmed by the postoperative control MR. After transient language worsening, all patients recovered to normal 3-6 months later. Language functional MR scannings have shown language functional cortical and subcortical pathway reorganization （in the perilesion or contra-lateral hemisphere） after the operation. All patients returned to a normal socioprofessional life. Conclusions By utilizing the dynamic interaction between brain plasticity and fractionated resections, we can totally remove the tumor involving Broca＇s structure without inducing permanent postoperative deficits and even improve the quality of life.

为进一步探究桥梁雍水计算中各经验公式的适用性,以山区河流梅溪的六座桥梁为例,借助FLOW3D三维水动力模型构建了精细化河道与桥梁三维模型,计算了不同重现期下的桥前雍水值。模型经验证后,FLOW3D模拟值的绝对误差小于0.07 m,Nash系数均大于0.8,表明模型模拟效果较好。对比分析了FLOW3D模拟值与四种不同桥梁雍水经验公式的雍水计算值,结果表明:从整体来看,铁科院曹瑞章公式的计算结果都相对较大。对于下游的三座桥梁,铁科院陆浩公式的计算结果偏大,道布松公式与Henderson公式的计算结果偏小,其中Henderson公式最接近于模拟值。此外,相对较上游的两座桥梁,陆浩公式的适用性更好。研究成果可以为桥梁雍水计算与研究区防洪评价提供参考。
