Litchi (Litchi chinensis Sonn.) is a well-known tropical and subtropical woody fruit that originated from southern China (Wei et al.,2017;Hu et al.,2022).Based on the development of the embryo,litchi varieties can be divided into three distinct groups:large-seeded cultivars,small (abortive)-seeded cultivars and partial abortive-seeded cultivars.Seedless or the reduction in seed size due to embryo abortion is a desirable trait in fruit trees as it directly influences the texture and economic value of fleshy fruits,making small (abortive)-seeded litchi cultivars the most preferred.However,in current production practices,there is no efficient method available to induce or promote high seed abortion in litchi fruit.Therefore,understanding the stenospermy mechanisms of litchi seed development is of great significance for improving agricultural practices and managing genetic resources. 展开更多

The developmental origins of health and diseases(DOHaD)is a concept stating that adverse intrauterine environments contribute to the health risks of offspring.Since the theory emerged more than 30 years ago,many epidemiological and animal studies have confirmed that in utero exposure to environmental insults,including hyperglycemia and chemicals,increased the risk of developing noncommunicable diseases(NCDs).These NCDs include metabolic syndrome,type 2 diabetes,and complications such as diabetic cardiomyopathy.Studying the effects of different environmental insults on early embryo development would aid in understanding the underlying mechanisms by which these insults promote NCD development.Embryonic stem cells(ESCs)have also been utilized by researchers to study the DOHaD.ESCs have pluripotent characteristics and can be differentiated into almost every cell lineage;therefore,they are excellent in vitro models for studying early developmental events.More importantly,human ESCs(hESCs)are the best alternative to human embryos for research because of ethical concerns.In this review,we will discuss different maternal conditions associated with DOHaD,focusing on the complications of maternal diabetes.Next,we will review the differentiation protocols developed to generate different cell lineages from hESCs.Additionally,we will review how hESCs are utilized as a model for research into the DOHaD.The effects of environmental insults on hESC differentiation and the possible involvement of epigenetic regulation will be discussed. 展开更多

This paper will Define what is meant by key terms such as legal tradition and endowment, explain the channels through which legal tradition and endowment affect financial development through talking about the relationship between legal origin, initial in endowment and financial development. By comparing different legal traditions or the"Origins"between the The Continental Law System and Common Law System, a comprehensive analysis of the effects of different origin of law on the financial and economic development. 展开更多

China is currently vigorously implementing the“energy conservation and emission reduction”and“dual carbon”strategies.As the most resource-advantaged light metal material in China,Magnesium(Mg)alloy is progressively expanding its application in automobile,rail transportation,aerospace,medical,and electronic products.Chongqing University,Shanghai Jiaotong University,and Australian National University have conducted extensive research on the preparation,properties,and processes of Mg alloys.In the past 20 years,the proportion of Mg alloy in the automotive industry has gradually expanded,whereas currently the design and development of Mg alloy parts for automobiles has rarely been reported.Thus,the application models and typical parts cases of Mg alloy are summarized mainly from the four systems of the whole vehicle(body system,chassis system,powertrain system,interior,and exterior system).Subsequently,two actual original equipment manufacturers(OEM)cases are used to introduce the development logic of reliable die-cast Mg alloy,including forward design,formability analysis,process design analysis,structural redesign,manufacturing,and testing,aiming to share the methods,processes,and focus of attention of automotive OEMs for developing Mg alloy parts to enhance the confidence and motivation of applying Mg alloy in automotive field.Eventually,the multiple challenges faced by Mg alloy materials are sorted out and how to face these challenges are discussed.National policies and regulations,environmental protection and energy saving,and consumer demand will continue to promote the application of Mg. 展开更多

Based on the theory of structural analysis,the characteristics and structural patterns of subtle faults are studied using 3D seismic data of the Bohai Sea to analyze the development process and origin of the subtle faults.A method of identifying subtle faults is proposed,forming a complete system for analyzing origins of subtle faults in the Bohai Sea.The complex strike-slip fault patterns under the strike-slip and extension stress background,diverse formation rocks,and strong neotectonic movement are the reasons for the development of subtle faults.According to the tectonic origin and development location,the subtle faults in Bohai Sea can be divided into 12 types in the three categories of strike slip dominant,extension dominant and strike slip and extension composite,and the different types of subtle faults occur in different regions of the Bohai Sea.Unreasonable variation of sedimentary stratum thickness,inherited distortion or even abrupt change of stratum occurrence,zonation of plane fault combination and the variation of oil-water system in the same structure with no-lithologic change are the important signs for identifying subtle faults in Bohai Sea.The subtle faults greatly enlarge the size of the structural trap groups,and areas with dense subtle faults are often active area of hydrocarbon migration and accumulation and favorable exploration zones,which have strong control on the hydrocarbon accumulation.The identification method for subtle faults has guided the exploration in the mature areas of Bohai Sea effectively,with a number of large and medium oil and gas fields discovered,such as Bozhong 29-6 and Penglai 20-2. 展开更多

It is based on people's ambitions for a better life and carries beautiful wishes. These beautiful roots are ultimately derived from "love", in the dance based on the image of people. Dance art expresses the love between people, the love of human and nature, the love of human and society;in the dance works based on the object, the intrinsic connection between nature and the natural world is also reflected. This paper expounds the cognition of dance in terms of children's dance enlightenment, limb development, aesthetic education, etc., and promotes the continuous development of the dance cause, cultivates more outstanding dancers, and creates more excellent dance works. 展开更多
