1Thirty million year deep-sea records in the South China Sea显示文摘In the spring of 1999 the Ocean Drilling Pro-gram (ODP) Leg 184 Shipboard Party cored 17 holes at 6 deep water sites in the northern and southern parts of the South China Sea (SCS). Chinese scientists actively partici-pated in the entire process of this first deep-sea drilling leg off China, from proposal to post-cruise studies. More than 30 categories of analyses have been conducted post-cruise in various Chinese laboratories on a large number of core sam-ples, and the total number of analyses exceeded 60 thousand. The major scientific achievements of the Leg 184 studies are briefly reported in three successive papers, with the first one presented here dealing with deep-sea stratigraphy and evolu-tion of climate cycles. This ODP leg has established the best deep-sea stratigraphic sequences in the Western Pacific: the 23-Ma isotope sequence from the Dong-Sha area is unique worldwide because of its continuity; the last 5-Ma sequence from the Nansha area represents one of the best 4 ODP sites worldwide with the highest time-resolution for that time in-terval, and the sequences of physical properties enable a de-cadal-scale time resolution. All these together have provided for the first time high-quality marine records for paleoenvi-ronmental studies in the Asian-Pacific region. This new set of stratigraphic records has revealed changes in climate cyclic-ity over the last 20 Ma with the fluctuating power of the 100 ka, 400 ka, 2000 ka eccentricity cycles, indicating the evolv-ing response of the climate system to orbital forcing along with the growth of the Antarctic and Northern Hemisphere ice sheets.WANGPinxian ZHAOQuanhong JIANZhimin CHENGXinrong HUANGWei TIANJun WANGJiliang LIQianyu LIBaohua SUXin 2003Chinese Science Bulletin2003,48,23:41
2Evolution of the South China Sea and monsoon history revealed in deep-sea records显示文摘As the third summary report of ODP Leg 184 to the South China Sea (SCS), this paper discusses the evolution of the East Asian monsoon and the SCS basin. A multi-proxy approach, involving geochemistry, micropaleontology, pollen and other analyses, was adopted for reconstructing the evolutionary history of the East Asian monsoon, which was characterized by a series of paleo-climate events especially at 8, 3.2, 2.2 and 0.4 Ma. The new record indicates similar stages in the development of the East and South Asian monsoons, with an enhanced winter monsoon over East Asia being the major difference. The rich spectrums of monsoon variability from the southern SCS also reveal other characteristic features of the low latitude ocean. Evidence for the evolution of the SCS includes the hemipelagic Oligocene sediments, implying the existence of deep water environments during the early seafloor spreading stage of the SCS basin. The four major unconformities and some remarkable diagenetic features in upper Oligocene deposits indicate the strongest tectonic events in the region. From a careful comparison of lithologies and sedimentation rates, we conclude that the prominent differences in sedimentary environments between the southern and northern SCS were established only by ~3 Ma.WANGPinxian JIANZhimin ZHAOQuanhong LIQianyu WANGRujian LIUZhifei WUGuoxuan SHAOLei WANGJiliang HUANGBaoqi FANGDianyong TIANJun LIJianru LIXianhua WEIGangjian SUNXiangjun LUOYunli SUXin MAOShaozhi CHENMuhong 2003Chinese Science Bulletin2003,48,23:34
3Volcanism at the Permian-Triassic Boundary in South China and Its Effects on Mass Extinction显示文摘This paper discusses the clayrocks widespread at the Permian-Triassic boundary, which are mostly of volcanic origin. Volcanogenetic textures, structures and minerals such as high-temperature quartz are found in clayrocks at the Permian-Triassic boundary in many places. Thousands of microspherules have been collected from the Boundary clayrocks, many of which exhibit the typical features of the process from melting to cooling and solidification. indicating that they were formed by volcanic eruption or extraterrestrial impact. Volcanic effects on the Permian-Triassic mass extinction may be reflected in conodonts, algae and ammonoids. The Boundary clayrocks are found in many Permian-Triassic sections along the coast of Tethys. Their orighin remains to be studied.Yin Hongfu, Huang Siji, Zhang Kexin, Yang Fengqing, Ding Meihua, Bi Xianmei and Zhang Suxin China University of Geosciences, Wuhan, Hubei 1989Acta Geologica Sinica(English Edition)1989,63,4:22

5Preparation of Mullite Whiskers and Their Enhancement Effect on Ceramic Matrix Composites显示文摘Mullite whiskers were facilely prepared by sintering kyanite at high temperature, with the addition of AlF3·3H2O. The as-prepared whiskers have been characterized systematically in terms of phase composition, morphology, and structure. Results showed that the morphology and size of mullite whiskers were strongly depended on the content of AlF3·3H2O and sintering temperature. At temperatures in the range of 1 100 to 1 500 ℃ with 4 wt% addition of AlF3·3H2O, the well-shaped mullite whiskers were obtained. For an instance, the mullite whiskers with 5-10 μm in length and 0.1-0.2 μm in cross-section could be formed at 1 400 ℃, with 4 wt% addition of AlF3·3H2O. Moreover, results showed that the addition of mullite whiskers into ceramic matrix enhanced its fracture toughness significantly.张锦化 WU Hongdan ZHANG Suxin Yu Jishun 侯书恩 2013Journal of Wuhan University of Technology(Materials Science)2013,28,3:9
6A simplified decoding algorithm for multi-CRC polar codes显示文摘Polar codes represent one of the major breakthroughs in 5G standard,and have been proven to be able to achieve the symmetric capacity of binary-input discrete memoryless channels using the successive cancellation list(SCL)decoding algorithm.However,the SCL algorithm suffers from a large amount of memory overhead.This paper proposes an adaptive simplified decoding algorithm for multiple cyclic redundancy check(CRC)polar codes.Simulation results show that the proposed method can reduce the decoding complexity and memory space.It can also acquire the performance gain in the low signal to noise ratio region.YANG Haifen YAN Suxin ZHANG Hao REN Yan HU Xiangdong LIN Shuisheng 2020Journal of Systems Engineering and Electronics2020,31,1:5
7Generation of male-sterile soybean lines with the CRISPR/Cas9 system显示文摘Soybean [Glycine max(L.) Merr.] provides a rich source of plant protein and oil worldwide. The commercial use of transgenic technology in soybean has become a classical example of the application of biotechnology to crop improvement. Although genetically modified soybeans have achieved commercial success,hybrid soybean breeding is also a potential way to increase soybean yield. Soybean cytoplasmic malesterile(CMS) lines have been used in three-line hybrid breeding systems, but their application to exploiting soybean heterosis has been limited by rare germplasm resource of sterile lines. The generation of various genetic diversity male-sterile soybean lines will help to overcome the shortcoming. In this study,we used targeted editing of AMS homologs in soybean by CRISPR/Cas9 technology for the first time to generate stable male-sterile lines. Targeted editing of GmAMS1 resulted in a male-sterile phenotype,while editing of GmAMS2 failed to produce male-sterile lines. GmAMS1 functions not only in the formation of the pollen wall but also in the controlling the degradation of the soybean tapetum.CRISPR/Cas9 technology could be used to rapidly produce stable male-sterile lines, providing new sterile-line materials for soybean hybrid breeding systems.Xiao Chen Suxin Yang Yaohua Zhang Xiaobin Zhu Xinjing Yang Chunbao Zhang Haiyan Li Xianzhong Feng 2021The Crop Journal2021,9,6:3
8Timing of the terrestrial Permian-Triassic boundary biotic crisis:Implications from U-Pb dating of authigenic zircons显示文摘The Late Permian to Early Triassic transition represents one of the most important Phanerozoic mass extinction episodes. The cause of this event is still in debate between catastrophic and gradual mechanisms. This study uses the U-Pb method on zircons from the uppermost Permian/lowermost Triassic clay deposits at Chahe (Guizhou Province, SW China) to examine time constraints for this event. The results of both this and previous studies show that the ages of Bed 68a and 68c (the upper clay bed of the terrestrial Permian-Triassic boundary (PTB)) respectively are 252.6±2.8 and 247.5±2.8 Ma. This age (within the margin of error) almost accords with the upper clay bed (Bed 28) age of Meishan and the eruption age of Tunguss Basalt, and is so far the most accurate age obtained from terrestrial PTB. The claystone of Bed 68 was formed in the earliest Triassic. The biotic crisis occurred at nearly the same time in terrestrial and marine environments during Permian-Triassic interval; however the extinction patterns and processes are different. The extinction pattern of the terrestrial plants shows a major decline at the PTB after long-term evolution, followed by a retarded extinction of the relicts in the earliest Triassic.YU JianXin LI HuiMin ZHANG SuXin YANG FengQing FENG QingLai 2008Science China Earth Sciences2008,51,11:2

10The miR166 mediated regulatory module controls plant height by regulating gibberellic acid biosynthesis and catabolism in soybean显示文摘MicroRNAs(miRNAs)are endogenous small noncoding RNAs that play critical roles in regulating plant growth and development.Here,we used Short Tandem Target Mimic(STTM)technology to generate soybean(Glycine max(L.)Merr.)miRNA knockdown lines and identify miRNAs that regulate plant height,a key agronomic trait that affects yield.STTM166 successfully silenced miR166 in soybean and upregulated the expression of miR166 target genes,such as ATHB14-LIKE.The miR166 knockdown lines(GmSTTM166)displayed a reduced plant height phenotype.Moreover,GmSTTM166 plants contained lower levels of bioactive gibberellic acid(GA3)than wild-type plants,and application of exogenous GA partially rescued the dwarf phenotype of GmSTTM166.Knockdown of miR166 altered the expression of genes involved in GA biosynthesis and catabolism.Further analysis revealed that ATHB14-LIKE directly represses transcription of the GA biosynthesis genes Gm GA1 and Gm GA2,while activating transcription of the GA catabolic gene GIBBERLLIN 2 OXIDASE2(GmGA2ox2).Collectively,these results reveal a pivotal role for miR166 in the genetic control of plant height in soybean,thereby providing invaluable insights for molecular breeding to improve soybean yield.Chen Zhao Jingjing Ma Yaohua Zhang Suxin Yang Xianzhong Feng Jun Yan 2022Journal of Integrative Plant Biology2022,64,5:1

20Combining magnetocaloric and elastocaloric effects in a Ni45Co5Mn37In13 alloy显示文摘1.Introduction Refrigeration plays an essential role in nowadays society.However,conventional refrigeration based on vapor compression cooling shows high energy consumption,complicated structure and even environmental pollution.Searching for an environmentalfriendly and energy-saving refrigeration technology has become a matter of concern[1,2].In the past few decades,the solid-state refrigeration technologies mainly represented by magnetocaloric effect(MCE),electrocaloric effect(ECE)and elastocaloric effect(e CE)have been regarded as promising candidate to replace traditional vapor compression refrigeration technology owing to environmental friendliness and high efficiency[1-9].Pengtao Cheng Zhenjia Zhou Jiaxing Chen Zongbin Li Bo Yang Kun Xu Zhe Li Jun Li Zhengming Zhang Dunhui Wang Suxin Qian Youwei Du 2021Journal of Materials Science & Technology2021,,35:0
