Resource constraint,sustainable economic growth pattern and transformation of economic system in China

Over the past 20 years, China has made spectacular achievements in economic growth as well as in thetransformation of economic growth pattern. Industrial structure is being updated, and technology is playing a more andmore important role in economic development. The energy and resource consumption in many industries and enterprisesare reducing. However, we should realize that there are still many problems in changing the economic growth pattern,such as high input, high consumption, high discharge, inharmony, recycling difficulty, and low efficiency, which havegreatly impaired and restrict Chinese economic development. Therefore, the fundamental change of the economic growthpattern is inevitable. Based on the analysis on the status quo and the exploit of resources, this paper suggests that thetransformation from unsustainable to sustainable growth is the only choice in changing the economic growth pattern. Inaddition, the transformation should not completely rely on the fundamental effects of market mechanism. We should makefull use of the power of governments to speed up the transformation of economic system.

基于自适应快速S变换和XGBoost的心电信号精确快速分类方法

针对心电信号(ECG)传统分类方法效率较低的问题,该文提出一种基于自适应快速S变换(AFST)和XGBoost的心电信号精确快速分类方法。该方法首先通过快速定位算法确定心电信号特征频率点,再根据特征频率点自适应调节S变换窗宽因子,增强S变换的时频分辨率的同时避免迭代计算,大大减少运行时间。其次,基于自适应快速S变换的时频矩阵提取12个特征量来表征5种心电信号的特征信息,特征向量维数低,识别能力强。最后,利用XGBoost算法对特征向量进行识别。MIT-BIH心律失常数据库和患者实测数据验证表明,该方法显著地缩短了分类时间,对5种心电信号的分类准确率分别为99.59%和97.32%,适用于实际检测系统中心律失常疾病的快速诊断。

Urban environmental problems transition and environmental education towards sustainable cities in China

With the rapid economic development and the speeding up of urbanization, the urban environmental problems in China are experiencing a progressive transition, which is characterized by steady transferring to the living (or consumption) oriented pollution pattern from the production oriented pollution pattern. Regarding this transition, the environmental education recognized as an important measure for approaching the objective of sustainable development, should transfer its focus correspondingly in urban area, which is to transfer to the habit cultivating pattern on the basis of the traditional knowledge inputting environmental education pattern. In practice, the urban environmental education should emphasize more on developing or cultivating the sustainable living mode of the urban residents, especially the students in elementary and primary schools and women. By this transform, the environmental education may be guided further towards sustainable development, and to serve the achievement of sustainable cities better in China.

Five trends of education and technology in a sustainable future

Quality education is one of the pillars in the United Nations 2030 Agenda for Sustainable Development,which aims to ensure inclusive and equitable quality education and promote lifelong learning opportunities for all.This overall goal can be connected to some general trends affecting education in the information age.We argue that education is key to the future quality of human life and the sustainability of the world.Generally,education is being transformed in both formal and informal learning contexts by new digital technologies.Overall,some of these major innovations and how they are changing education can be summarized into the following aspects:1)our educational aims and objectives;2)educational ecologies and contexts of learning;3)the processes of learning;4)the processes of teaching;and 5)educational governance and policy.Meanwhile,we note some of the potential risks and downsides of these technology trends.From the sustainable perspective,our review points to a great potential for educational reform,but it can only be achieved if we are willing to rethink and even abandon some of our traditional ways of doing things in education.

Prediction-Adaptation-Resilience(PAR)approach-A new pathway towards future resilience and sustainable development of urban landscape

Urban land-use planning,especially in the peripheral region,has become an issue in contemporary urban stud-ies.Simultaneously,urban resilience is very indispensable for future urban land use planning and management.Therefore,consistent urban proliferation can be coped through Prediction-Adaptation-Resilience(PAR),to accom-plish future urban land use and sustainable development of any growing up urban areas worldwide.Therefore,different dynamic simulation models,e.g.Cellular automata-Markov model,artificial neural network,are used to project and predict any urban areas’spatial growth.Then,the adaptation strategies are taken to assess the urban land use transformation in the past and present context.Those strategies help to strengthen urban land use planning using an integrated supply and demand chain.Finally,this study checks the resilience of how much it will be threatened or saved for future sustainable urban developmental goals and urban resilience.Therefore,it is important to establish a conceptual framework to achieve Sustainable Development Goals(SDGs)based on principles of the PAR approach.Advocating the on-going adaptation of sustainability,resilience,and rapid urban transformation in the developing cities requires clear and explicit definitions that are embedded with the recent and particular context.Thus,government and policy makers should draw their attention to make proper urban landscape planning and adaptation strategies for the future urban expansion in a holistic way by maintaining appropriate urban resilience.

SUSTAINABLE DEVELOPMENT FACING CHALLENGESIN 21ST CENTURY

ABSTRACT: The 21st Century is the time for human seeking harmonizing with environment and carrying out sustainable development strategy. But sustainable development is facing many challenges. They may mainly include the follows: challenge comes from the contradiction between human and the earth, challenge of local benefit conflict to human common goal, challenge of competition to fairness, challenge of unbalanced development in regions and countries, challenge of diversity and challenge of calamity. Challenges are not only pressure, but also the motive force. Challenge exists, the motive force would never stop. Sustainable development was born in challenges, is developing in contradiction and will sustain in conflict.

High impedance fault detection in distribution network based on S-transform and average singular entropy

When a high impedance fault(HIF)occurs in a distribution network,the detection efficiency of traditional protection devices is strongly limited by the weak fault information.In this study,a method based on S-transform(ST)and average singular entropy(ASE)is proposed to identify HIFs.First,a wavelet packet transform(WPT)was applied to extract the feature frequency band.Thereafter,the ST was investigated in each half cycle.Afterwards,the obtained time-frequency matrix was denoised by singular value decomposition(SVD),followed by the calculation of the ASE index.Finally,an appropriate threshold was selected to detect the HIFs.The advantages of this method are the ability of fine band division,adaptive time-frequency transformation,and quantitative expression of signal complexity.The performance of the proposed method was verified by simulated and field data,and further analysis revealed that it could still achieve good results under different conditions.

A discussion on cotton transformation during the last decade (2010–2021);an update on present trends and future prospects

The introduction of genetically modified(GM)cotton in 1996 in the US and its worldwide spread later rejuvenated cotton production in many parts of the world.The evolution is continued since then and currently,the 3rd and fourth generation of same GM cotton is grown in many parts of the world.The GM cotton introduced in 1996 was simple Bt cotton that expressed a single Cry1Ac gene,the later generation carried multiple Cry genes along with the genes controlling herbicide tolerance.Current day GM cotton does not only give stable resistance against lepidopteran insects but also facilitates the farmers to spray broad-spectrum herbicides without harming the crop.The evolution of GM cotton is continued both on the basic and applied side and interventions have been introduced during the last decade.Earlier the cotton transformation was limited to Cocker strains which are getting possible in many other varieties,too.It is successful with both gene gun,and Agrobacterium and inplanta transformation has made it a routine activity.Apart from overexpression studies for various purposes including biotic,abiotic,and quality traits,RNAi and genome editing are explored vigorously.Through this review,we have tried to explore and discuss various interventions for improving transformation protocols,the applications of cotton transformation,and future strategies being developed to get maximum benefits from this technology during the last decade.

Mass Customization and Design for High Density Indemnificatory Housing in China

The use of computer in architectural design shouldn’t sacrifice the pursuit of a human-oriented built environment.The technological applications should be legitimated by the objectives and motivations in multiple dimensions,but not abuse its generative power against the social and cultural interests.This article is based upon our synthetic computational design research for high density indemnificatory housing in China(Fig.1),which challenges the conventional standard design for large scale social housing in the Industrial Era,and reflects our exploration for innovative,multi-disciplinary,systematic and synthetic design in the new design paradigm of computation.It also promotes to shift the privilege of cutting-edge design techniques and avant-garde concepts from the“High(end)Architecture”to the ordinary architecture during the unprecedented built-environment development in China.Architectural design should have no discrimination between the Olympic stadiums in the capital and the social housing in the subordinate developed cities,as they both need to be innovative and meaningful.The final design research outputs address sustainable transformation initiated by the residents during the whole life span of the housing.We believe that the human factor(including stakeholders,users,designers and builders)is even more important in architectural design,city planning,urban design,landscape and interior design while technology development is accelerating.Conceptualization,imagination and systemization would become significant pacemakers which perpetuate design innovation.
