Establishment of the integrated applied core collection and its comparison with mini core collection in soybean(Glycine max)

The concept of core collection(CC) provides a new way of management and utilization of plant germplasm resources. In this study, an integrated applied core collection(IACC) of soybean was developed based on evaluation data for desirable agronomic and nutritional traits of available soybean germplasm resources including accessions with cold tolerance, drought tolerance, salt tolerance, soybean cyst nematode resistance, soybean mosaic virus resistance, high protein content, and high fat content. The newly formed collection encompasses accessions with high genetic diversity and desirable agronomic traits. The genetic diversity of the newly formed IACC was compared with that of the established mini core collection(MCC) of soybean with the aid of simple sequence repeat(SSR) markers and phenotypic traits. The results showed that at the molecular level, soybean IACC harbored a similar level of genetic diversity as the established MCC, and that at the phenotypic level the IACC encompasses more accessions with desirable traits than does the established MCC. The development of soybean IACC lays a foundation for breeding projects to meet different objectives in different eco-regions.

Strategies on Sample Size Determination and Qualitative and Quantitative Traits Integration to Construct Core Collection of Rice (Oryza sativa)

The development of a core collection could enhance the utilization of germplasm collections in crop improvement programs and simplify their management. Selection of an appropriate sampling strategy is an important prerequisite to construct a core collection with appropriate size in order to adequately represent the genetic spectrum and maximally capture the genetic diversity in available crop collections. The present study was initiated to construct nested core collections to determine the appropriate sample size to represent the genetic diversity of rice landrace collection based on 15 quantitative traits and 34 qualitative traits of 2 262 rice accessions. The results showed that 50-225 nested core collections, whose sampling rate was 2.2%-9.9%, were sufficient to maintain the maximum genetic diversity of the initial collections. Of these, 150 accessions （6.6%） could capture the maximal genetic diversity of the initial collection. Three data types, i.e. qualitative traits （QT1）, quantitative traits （QT2） and integrated qualitative and quantitative traits （QTT）, were compared for their efficiency in constructing core collections based on the weighted pair-group average method combined with stepwise clustering and preferred sampling on adjusted Euclidean distances. Every combining scheme constructed eight rice core collections （225, 200, 175, 150, 125, 100, 75 and 50）. The results showed that the QTT data was the best in constructing a core collection as indicated by the genetic diversity of core collections. A core collection constructed only on the information of QT1 could not represent the initial collection effectively. QTT should be used together to construct a productive core collection.

Understanding the Traditional Saudi Built Environment: The Phenomenon of Dynamic Core Concept and Forms

This study examines the traditional Saudi built environment and culture to uncover its rich architecture and to propose a new way of thinking about how to comprehend and value the past while also rebalancing the Kingdom’s future architectural identity. In that sense, the primary objective of this study is to examine the Core Concepts and Forms of traditional architecture, as well as their cultural connotations, in three regions of Saudi Arabia: the central, eastern, and western regions. Non-participant observation, ethnographic, and descriptive approaches were used in the study, which was based on a multi-dimensional comparative observational model. It was determined that the traditional Saudi built environment relied on forty Core Concepts and Forms that were divided into four categories: constant, semi-constant, semi-flexible, and flexible core forms to regulate the production process and maintain its continuity over centuries.

Integration and verification case of IP-core based system on chip design

In this paper, the design and verification process of an automobile-engine-fan control system on chip （SoC） are introduced. The SoC system, SHU-MV08, reuses four new intellectual property （IP） cores and the design flow is accomplished with 0.35 btm chartered CMOS technology. Some special functions of IP cores, the detailed integration scheme of four IP cores, and the verification method of the entire SoC are presented. To settle the verification problems brought by analog IP cores, NanoSim based chip-level mixed-signal verification method is introduced. The verification time is greatly reduced and the first tape-out achieves success which proves the validity of our design.

A Study on the Integration of the Confucian Culture and the Core Values of China

Core value is an important guarantee for building a harmonious socialist society and the ideological and moral basis of the unity of the people of all ethnic groups in our country.In recent years,the cultivation and practice of core values have become more and more popular;the main thoughts of core values derive fromtraditional culture.In retrospect of our traditional culture,Confucian culture is not allowed to be ignored.Therefore,in the process of fostering and practicing the core values,we need to analyze the combination between Confucian culture and core values,and ingeniously fuse the Confucian culture into the core values,so that the connotation of the core values would more abundant.

职业教育专业核心课教材编写:理论与策略

职业教育专业核心课是由工作任务转化而来的、体现岗位(群)核心内容和行动逻辑的课程。专业核心课的“核心”体现在它是其他类型课程的内容源泉,是内容体系化和课程化的核心。专业核心课教材的编写要解决三个关键问题:如何在教材中实现理实一体化、教材中的理论知识如何选择和呈现、实践要素在教材中如何表达。基于知识论和学习论的视角分析发现,专业核心课教材主要承载的是技术理论知识和技术实践知识,教材要为任务学习和能力形成提供有意义的情境,根据知识特点选择教材中理实一体化的模式,基于学习规律优化技术理论知识与技术实践知识的呈现方式,同时要为教师和学生提供有效的评价工具。因此在教材内容的开发上,应组建校企编写团队并选择合适的开发策略;在内容的组织上,应确保教材最小构成单元的独立性;在教材的内容的呈现上,应基于知识特点优化内容的排布、表达和信息模态。

论中国文艺“走出去”的路径选择与策略应用

相比于三大产业“硬实力”的提升,中国文化产业的发展还有所差距,于是党中央明确提出了增强国家“软实力”,实施中国文化“走出去”的号召。文艺是文化的重要组成部分,也是传播文化的重要载体,自然必须增强“走出去”的意识,积极承担起讲好中国故事、传播好中国声音的时代使命,使海外受众能够通过文艺作品深化对中国文化的认识,增进对中国的了解。为了实现这种跨文化传播的目标,中国文艺创作必须进一步增强讲故事的能力,坚持传递中国核心价值,展示其广泛的人类价值;在历史和现实两种题材的创作中,分别深化时代的书写,呈现出传统与现代两种文化的神韵;确立鲜明的艺术风格,在民族性与世界性的融合中展现独特魅力;积极推进作品的翻译和推介体系构建,为世界奉献更多优秀的中国文艺作品,在跨文化传播中获得进一步的成功。

基于WOA-SVR的关键核心技术创新生态系统脆弱性预警研究——以集成电路技术为例

双循环格局下,创新生态系统脆弱性成为制约关键核心技术攻关的瓶颈,对其有效预警是实现技术突破、解决“卡脖子”问题的关键环节之一。结合集成电路技术发展现状,构建包含群落、资源、经济、环境4个子系统的关键核心技术创新生态系统,同时建立改进WOA-SVR的脆弱性预警模型,对系统脆弱性进行分级。结果表明,集成电路技术创新生态系统综合脆弱指数由2005年的4.28下降到2020年的2.66,警度从较重警情降至中警;经济子系统作为创新生态系统最活跃的子系统,其脆弱性指数下降缓慢,仍处于较高脆弱度水平。对4个子系统指标间耦合关系进行剖析发现,适应能力指标对降低系统脆弱性指数具有较大影响,政府和企业可据此建立防范机制。

高考跨学科命题透视:特点、问题与改进建议——基于对2016-2023年210份全国卷的分析

高考作为衡量学生学业水平的权威性高利害考试,是我国人才培养的重要指挥棒和风向标。新课标和新高考改革明确强调问题导向、学科融合的基本取向,对跨学科命题提出了新要求。为了把握高考跨学科命题的总体概况,有必要基于高考全国试卷对其跨学科命题进行深入分析。通过对2016—2023年共210份高考全国卷中的跨学科试题所考查的学科知识内容、核心素养水平、问题情境等进行编码分析发现:当前我国高考跨学科试题数量约占总题量的10%,与新课标所要求的课时比例相匹配;跨学科命题整体呈现出能力本位、问题开放、形式多样的特点,但仍然存在文理内部组合远多于文理交叉组合,学科融合程度不够高,学科核心素养的组合方式相对固定且频次分布不均衡,学科核心素养考查水平不高等问题。未来高考跨学科命题应从学科知识锚定、学科融合水平提升和核心素养考查三个方面进行综合考量,并不断提升命题质量。具体而言,可通过增强试题的情境化创设,突出不同学科之间的交叉关联点,以命制文理交叉的跨学科试题;可通过提炼跨学科大概念,并提供相应的引导和提示,以命制超学科融合水平的试题;还可通过构建核心素养所对应的学科知识体系,并与相关学科建立情境关联,以命制素养导向的跨学科试题。

马克思主义视角下乡村振兴的理论内核与实现路径

马克思主义为乡村振兴战略提供丰富的学理依据,是地域分工理论、城乡关系理论和生态文明理论在新时代中国特色社会主义建设中的又一生动实践。从现实来看,实施乡村振兴战略是中国特色社会主义的本质要求,是化解我国不平衡不充分矛盾的必然选择,也是实现我国可持续发展的有效路径。从马克思主义理论来看,乡村振兴是量变与质变的辩证统一,也是生产力水平的发展和社会分工的高级化的必然结果。其中,人的全面发展是乡村振兴的主体条件,人与自然的辩证统一是乡村振兴的重要组成部分。在此基础上,提出包括缩小城乡生产力水平差距、建设城乡要素双向流动的体制机制、推动城乡合作迈向新阶段和促进基本公共服务均等化等实现路径,为乡村振兴战略的实施提供政策支持。
