Status quo and outlook of reconfigurable research

Li Yufeng,Qiu Han,Lan Julong

Strategic Study of CAE 2008, Volume 10, Issue 7,   Pages 82-89

Abstract:

Today, with new services and applications blooming on the internet, to enable traditional routers to offer enough capability and speed of upgrade along with these services and applications in time would become even harder than ever. Run-time reconfiguration (RTR), based on the Field Programmable Gate Array (FPGA), is a new promising technology that can configure the partial or total hardware logic resources of a system at run time. Based on the technology, reconfigurable routers can support dynamic reconfiguration of new hardware logic for the new service, while keeping the other services still run properly, hence can provide a new possible solution to the update problem of the traditional routers. After introducing the basic concepts of RTR and the current development of the FPGA, this paper summarizes the past major research efforts with respect to the reconfigurable router, as well as the current work on it. Research directions and open problems are also discussed from the point of view of reconfigurable network.

Chen Yuanhua,Yang Yanping,Hu Shuhan,Xie Linming,Yang Yang,Huang Wei and Chen Zhilin

Strategic Study of CAE 2018, Volume 20, Issue 1,   Pages 113-119 doi: 10.15302/J-SSCAE-2018.01.016

Abstract:

This work discusses the importance of improving the recycling and utilization of end-of-life vehicles through three perspectives that include resource saving, environmental protection, and transportation safety. It then analyzes the situation of recycling and utilizing end-of-life vehicles by using the recycle rate of end-of-life vehicles and their dismantling ability, as well as the administrative regulations and supervising system. Based on this analysis, we propose an ecologically beneficial evaluation model for the recycling and utilization of end-of-life vehicles to solve the existing problem.

Status Quo of International Cooperation in Competitive Industries and Manufacturing in the Six Economic

Tang Yongchuan,Pan Yunhe, Zhang Xue, Hang Jiangjie

Strategic Study of CAE 2019, Volume 21, Issue 4,   Pages 60-68 doi: 10.15302/J-SSCAE-2019.04.003

Abstract:

The construction of the Belt and Road is shifting from overall planning to concrete implementation, which sets higher demands for international cooperation of China’s manufacturing industry. Based on 2016 statistics of the UN Comtrade Database, this paper focuses on the six economic corridors of the Belt and Road, and uses the revealed comparative advantage index to comprehensively analyze the comparative industries in these countries. Meanwhile, the multidimensional scaling method is adopted to explore the overall trade and manufacturing cooperation between China and these countries. Finally, based on the competitive industries and factor endowments of the countries in the six economic corridors, the development direction for high-quality cooperation between China and the countries along the Belt and Road is proposed.

Current status and prospects of reliability systems engineering in China

Frontiers of Engineering Management 2021, Volume 8, Issue 4,   Pages 492-502 doi: 10.1007/s42524-021-0172-2

Abstract: This study provides a systematic overview of the advent and evolution of reliability systems engineering (RSE) in China, and the latest RSE development, that is, model-based RSE (MBRSE), is emphatically introduced. The establishment of the system architecture and conceptual models of MBRSE is first described. The fundamental theory and methodology of MBRSE are then elaborated, with a V-model as the core of this approach. The development of various MBRSE platforms and the effectiveness of their implementation over the past 30 years are presented. The prospective trends in the development of RSE in China are outlined.

Present status and progress of neoadjuvant chemoradiotherapy for esophageal cancer

Jing Liu, Jinbo Yue, Ligang Xing, Jinming Yu

Frontiers of Medicine 2013, Volume 7, Issue 2,   Pages 172-179 doi: 10.1007/s11684-013-0268-0

Abstract:

Trimodality based on neoadjuvant chemoradiotherapy (nCRT) followed by surgery is gaining popularity as a treatment strategy for locally advanced esophageal cancer. In this review, we summarize the role of nCRT and the recommended nCRT regimens based on clinical trials and meta-analyses. We analyze the relationship of nCRT with pathologic complete response (pCR) and then identify potential predictive markers of response. Compared with surgery alone and neoadjuvant chemotherapy followed by surgery, trimodality provides longer survival and has the advantage of local control compared with definitive chemoradiotherapy. The standard regimen is a platinum-based regimen with a radiation dose range of 41.4–50.4βGy by conventional fractionation. Evidence shows that patients with pCR tend to live longer than non-responders, indicating that pCR is a significant prognostic factor for patients with esophageal cancer. Individualized medicine requires predictive markers of individual patients based on their own genes. Currently, no definite marker is proved to be sufficiently sensitive and specific for use in clinical practice, although 18-fluorodeoxyglucose positron emission tomography shows promise in predicting response to nCRT.

EGG PRODUCTION IN CHINA: CURRENT STATUS AND OUTLOOK

Frontiers of Agricultural Science and Engineering 2021, Volume 8, Issue 1,   Pages 25-34

Abstract:

• China is now the largest egg production country worldwide

• Egg production in China is characterized by diversity in several aspects

• China is now capable of breeding new varieties, with more than 50% of the market share

• Policies have been implemented to ensure sustainable development of egg production

• Integrating crop-chicken-vegetable production system is established

 

Eggs are one of the most nutritious and affordable animal products worldwide. From 1985, egg production in China has retained the leading place in the world. A total of 33 Mt of eggs were produced in 2019 representing ˃ 40% of the world total production. Egg production in China is characterized by diversity in several aspects, including layer breeds, products and production systems. New breeds and synthetic lines are developed to improve the genetic potentials of egg production and feed efficiency of layers. In the past, layer farms were run mostly by small households with 100 to 1000 layers per farm. Over the past decades, egg production in China has developed toward standardization and expansion of production systems, and many of these modern intensive farms raise millions of layers. Although the Chinese egg products maintain strong competitiveness over other animal products and imported egg products, the egg industry will grow at a slower pace compared to the past. Chinese consumers are more concerned about the quality and safety of eggs and egg products, as well as the environmental issues related to animal production, which presents challenges for the Chinese egg industry.

Catalytic conversion of biomass-derived compounds to various amino acids: status and perspectives

Frontiers of Chemical Science and Engineering 2023, Volume 17, Issue 7,   Pages 817-829 doi: 10.1007/s11705-022-2254-z

Abstract: Amino acids are important nitrogen-containing chemicals that have a variety of applications. Currently, fermentation is the widely employed method to produce amino acids; however, the products are mostly limited to natural amino acids in the L-configuration. Catalytic synthesis is an alternative approach for the synthesis of amino acids with different types and configurations, where the use of renewable biomass-based feedstocks is highly attractive. To date, several lignocellulose and triacylglycerol-derived intermediates, typically α-keto acids and α-hydroxyl acids, have been transformed into amino acids via the amination reaction in the presence of additional nitrogen sources (i.e., NH3·H2O). Making full use of inherent nitrogen in biomass (i.e., chitin and protein) to produce amino acids avoids the use of extra nitrogen sources and meets the requirements of green chemistry, which is attracting increasing attention. In this review, we summarize different chemical-catalytic systems for the transformation of biomass to amino acids. An outlook on the challenges and opportunities for more effective production of amino acids from biomass by catalytic methods is provided.

Keywords： biomass     amino acids     chitin     nitrogen-containing compounds     lignocellulose
