摘要：Our society faces multiple daunting challenges including finding sustainable solutions towards climate change mitigation;efficient production of food,biofuels,and biomaterials;maximizing land-use efficiency;and enabling a sustainable *** can provide environmentally and economically sustainable solutions to these challenges due to their inherent capabilities for photosynthetic capture of atmospheric CO2,allocation of carbon to various organs and partitioning into various chemical forms,including contributions to total soil *** order to enhance crop productivity and optimize chemistry simultaneously in the above-and belowground plant tissues,transformative biosystems design strategies are *** research efforts will be required for accelerating the development of plant cultivars,genotypes,or varieties that are cooptimized in the contexts of biomass-derived fuels and/or materials aboveground and enhanced carbon sequestration ***,we briefly discuss significant knowledge gaps in our process understanding and the potential of synthetic biology in enabling advancements along the fundamental to applied research ***,a convergence of perspectives from academic,industrial,government,and consumer sectors will be needed to realize the potential merits of plant biosystems design for a carbon neutral bioeconomy.

摘要：The climate crisis associated with rapid accumulation of carbon dioxide in atmosphere has posed increasing threat to human wellbeings[1].It is of great significance to capture and convert CO2 to realize sustainable utilization of carbon resources[1].The electrocatalytic CO2 reduction reaction(CO2RR)provides a sustainable,carbon-neutral method for solving this *** the difficulty of finding an efficient catalysts slows down the realization of the ambitious *** is mainly because it requires simultaneous optimization of selectivity for a specific product,energy conversion efficiency,current density and stability of the reaction system.

摘要：Due to the popularity of English, English language teaching has taken up an important position in China＇s education. Teachers of English may seldom consider the power behind this widely-used language during the teaching process. This article starts with revealing the power behind language so as to let teachers be aware of the hidden power behind English language and be conscious that English language is not neutral. At the same time, it reminds teachers of English to have a critical attitude on their teaching practice and help students to balance the study of Chinese and English.

摘要：Governance is a process of establishing policies or laws and continuously monitoring their implementation in the public. Citizens are the main stakeholders in this process. To make the governance process cost effective, easy and convenient to the citizens, information and communication technologies (ICTs) are playing a vital role. Using ICTs in governance domain can be referred as e-governance. It helps citizen to participate not only in policy making but also in service quality improvements and getting government services over network. Web technology is one of the major technologies that have been used in e-governance as a major contributor. Before invention of web, citizens used to write their opinions and send to concerned body via post mail or local suggestion box for improvements of services. After the invention of the web, it became possible to post or send the opinions/comments over organization’s web sites or portals. As the number of comments increases over the web, it is very difficult to have relevant information for furthering the decision making processes. In these study, text processing and data mining techniques have been used. The prototype system classifies citizen’s opinions in one of six service categories with the precision of 87.3% and recall of 85.8%. Further, the system determines opinions as appreciation with the precision of 100% for both depression and appreciation, and average recall of 90.85% for both depression and appreciation. The results obtained from the prototype system indicate that the techniques that have been applied are promising for real world application in e-governance.

摘要：Genetic variations such as mutations and recombinations arise spontaneously in all cultured *** it is possible to identify nonneutral mutations by selection or counterselection,the identification of neutral mutations in a heterogeneous population usually requires expensive and time-consuming methods such as quantitative or droplet polymerase chain reaction and high-throughput *** mutations could even become dominant under changing environmental conditions enforcing transitory selection or *** propose a novel method,which we called qSanger,to quantify DNA using amplitude ratios of aligned electropherogram peaks from mixed Sanger sequencing *** expressing enhanced green fluorescent protein and mCherry fluorescent markers were used to validate qSanger both in vitro and in cotransformed Escherichia coli via quantitative polymerase chain reaction and fluorescence *** show that qSanger allows the quantification of genetic variants,including single-base natural polymorphisms or de novo mutations,from mixed Sanger sequencing reads,with substantial reduction of labor and costs compared to canonical approaches.
