| 1 | Terrestrial carbon sinks in China and around the world and their contribution to carbon neutrality显示文摘Enhancing the terrestrial ecosystem carbon sink(referred to as terrestrial C sink) is an important way to slow down the continuous increase in atmospheric carbon dioxide(CO_(2)) concentration and to achieve carbon neutrality target.To better understand the characteristics of terrestrial C sinks and their contribution to carbon neutrality,this review summarizes major progress in terrestrial C budget researches during the past decades,clarifies spatial patterns and drivers of terrestrial C sources and sinks in China and around the world,and examines the role of terrestrial C sinks in achieving carbon neutrality target.According to recent studies,the global terrestrial C sink has been increasing from a source of (-0.2±0.9) Pg C yr^(-1)(1 Pg=1015g)in the 1960s to a sink of (1.9±1.1) Pg C yr^(-1) in the 2010s.By synthesizing the published data,we estimate terrestrial C sink of 0.20–0.25 Pg C yr^(-1) in China during the past decades,and predict it to be 0.15–0.52 Pg C yr^(-1) by 2060.The terrestrial C sinks are mainly located in the mid-and high latitudes of the Northern Hemisphere,while tropical regions act as a weak C sink or source.The C balance differs much among ecosystem types:forest is the major C sink;shrubland,wetland and farmland soil act as C sinks;and whether the grassland functions as C sink or source remains unclear.Desert might be a C sink,but the magnitude and the associated mechanisms are still controversial.Elevated atmospheric CO_(2) concentration,nitrogen deposition,climate change,and land cover change are the main drivers of terrestrial C sinks,while other factors such as fires and aerosols would also affect ecosystem C balance.The driving factors of terrestrial C sink differ among regions.Elevated CO_(2) concentration and climate change are major drivers of the C sinks in North America and Europe,while afforestation and ecological restoration are additionally important forcing factors of terrestrial C sinks in China.For future studies,we recommend the necessity for intensive and long-term ecosystem C monitoring over broad geographic scale to improve terrestrial biosphere models for accurately evaluating terrestrial C budget and its dynamics under various climate change and policy scenarios. | Yuanhe Yang Yue Shi Wenjuan Sun Jinfeng Chang Jianxiao Zhu Leiyi Chen Xin Wang Yanpei Guo Hongtu Zhang Lingfei Yu Shuqing Zhao Kang Xu Jiangling Zhu Haihua Shen Yuanyuan Wang Yunfeng Peng Xia Zhao Xiangping Wang Huifeng Hu Shiping Chen Mei Huang Xuefa Wen Shaopeng Wang Biao Zhu Shuli Niu Zhiyao Tang Lingli Liu Jingyun Fang | 2022 | Science China(Life Sciences)2022，65，5： | 32 |
| 2 | Clay mineral composition and their sources for the fluvial sediments of Taiwan Residents rivers显示文摘Located at the collision boundary between the Philippine Sea Plate and the Eurasian Continental Plate,the island of Taiwan is generally recognized as an important example in the MARGINS Program Science Plan and 'source-to-sink' research because of its high tectonic activity,heavy rainfall and unique geography.Large suspended sediment loads are transported to the adjacent ocean by Taiwan Residents rivers every year,making Taiwan an important source of sediments into the adjacent seas and a natural laboratory for studying the systemic movement of fluvial sediments from source to sink.A detailed study on the clay mineral composition of surface sediments collected from the drainage basins of 12 Taiwan Residents rivers using X-ray diffraction methods was conducted.Our results indicated that the clay mineral assemblages consisted dominantly of illite(approximately 73%) and chlorite(approximately 24%),with lesser abundances of kaolinite(approximately 3%) and even lower levels of smectite from the Danshuei River sediments in northwestern Taiwan.The Jhuoshuei River sediments from western Taiwan contained clay mineral assemblages that consisted of illite(approximately 75%) and chlorite(approximately 25%),but they lacked kaolinite and smectite.In southwestern Taiwan,the clay mineral assemblages were dominated by illite(approximately 75%) and chlorite(approximately 23%),but had a low abundance of kaolinite(generally < 2%) and no smectite.The clay mineral assemblages in eastern Taiwan are obviously different from those in western parts of the island.The most noticeable difference is that the average abundance of chlorite in the Hualien River from eastern Taiwan was the highest(approximately 48%) of all the Taiwan Residents rivers.We concluded that,in general,the clay mineral assemblages in Taiwan Residents rivers were mainly composed of illite and chlorite with kaolinite and smectite being scarce,and these trends are different from those in China's mainland rivers.The clay mineral composition shown in this study was primarily determined by the properties of the bedrock,and the differential weathering intensities of the drainage area.The surface sediments in Taiwan's rivers showed a greater abundance of illite and chlorite because the outcropped rocks were mainly composed of Tertiary sedimentary rocks,especially sandstone,shale and slate,and show strong physical weathering.The relatively high relief and more abundant rainfall also caused the clay minerals in the fluvial sediments to be transported to the estuaries down rivers from the mountains and then delivered to the adjacent seas by currents and waves over a shorter time scale. | LI ChuanShun SHI XueFa KAO ShuhJi CHEN MinTe LIU YanGuang FANG XiSheng LUE HuaHua ZOU JianJun LIU ShengFa QIAO ShuQing | 2012 | Chinese Science Bulletin2012，57，6： | 23 |
| 3 | Effects of modified Lingguizhugan decoction combined with weekend fasting on metabolic syndrome显示文摘OBJECTIVE:To assess the therapeutic effect of weekend fasting and administration of a modified Lingguizhugan decoction on metabolic syndrome(MetS).METHODS:Twenty-one patients with MetS were recruited from the First Affiliated Hospital of Sun Yat-Sen University.Fasting plasma glucose(FPG),30-min and 2-h post-prandial blood glucose(PG),fasting serum insulin(FINS),blood pressure(BP),body mass index(BMI),waist circumference(WC),homeostasis model assessment for insulin resistance index(HOMA-IR),and levels of triglyceride(TG),total cholesterol(TC),low-density lipoprotein-cholesterol(LDL-C),and high-density lipoprotein cholesterol(HDL-C)were tested.Patients were allowed to drink only water and a Chinese herbal decoction during weekends.All samples were tested again after 12 weeks of treatment.RESULTS:FPG,30-min PG,2-h PG,FINS,LDL-C,systolic BP,diastolic BP,BMI,WC,and HOMA-IR de-creased significantly(P<0.05)compared with before treatment.Levels of TG,TC,and HDL-C did not change significantly.CONCLUSION:Weekend fasting improved glucose metabolism,lowered BP,reduced LDL-C levels,BMI,and WC.These data suggest that weekend fasting may be an effective therapy for MetS by protection against coronary atherosclerosis. | Yubin Yang Qiong Li Shuqing Chen Bin Ke Yinjuan Huang Jian Qin | 2014 | Journal of Traditional Chinese Medicine2014，34，1： | 8 |
| 4 | Enhanced ozonation of dichloroacetic acid in aqueous solution using nanometer ZnO powders显示文摘Nanometer zinc oxide(ZnO) powders were used as a catalyst to enhance the ozonation for the degradation of dichloroacetic acid(DCAA) in aqueous solution.The batch experiments were carried out to investigate the eflects of key factors such as catalyst dosage,ozone dosage,solution pH and tert-butyl alcohol(t-BuOH) on the degradation eflciency of DCAA.Density functional theory(DFT) was adopted to explore the mechanism of generating hydroxyl radical(.OH) on the ZnO surface.The results showed that adsorption and ozonation processes were not eflective for DCAA removal,and the addition of ZnO catalyst improved the degradation eflciency of DCAA during ozonation,which caused an increase of 22.8%for DCAA decomposition compared to the case of ozonation alone after 25 min.Under the same experimental conditions,the DCAA decomposition was enhanced by increasing catalyst dosage from 100 to 500 mg/L and ozone dosage from 0.83 to 3.2 mg/L.The catalytic ozonation process is more pronounced than the ozonation process alone at pH 3.93,6.88,and 10.With increasing the concentration of t-BuOH from 10 to 200 mg/L,the degradation of DCAA was significantly inhibited in the process of catalytic ozonation,indicating that ZnO catalytic ozonation followed.OH reaction mechanism.Based on the experimental results and DFT analysis,it is deduced that the generation of.OH on the ZnO surface is ascribed to the adsorption of molecule ozone followed by the interaction of adsorbed ozone with active sites of the catalyst surface.It is also concluded that ZnO may be an eflective catalyst for DCAA removal,which could promote the formation of.OH derived from the catalytic decomposition of ozone. | Xu Zhai Zhonglin Chen Shuqing Zhao He Wang Lei Yang | 2010 | Journal of Environmental Sciences2010，22，10： | 7 |
| 5 | Cylindrical vector beam multiplexer/demultiplexer using off-axis polarization control显示文摘The emergence of cylindrical vector beam(CVB)multiplexing has opened new avenues for high-capacity optical communication.Although several configurations have been developed to couple/separate CVBs,the CVB multiplexer/demultiplexer remains elusive due to lack of effective off-axis polarization control technologies.Here we report a straightforward approach to realize off-axis polarization control for CVB multiplexing/demultiplexing based on a metal–dielectric–metal metasurface.We show that the left-and right-handed circularly polarized(LHCP/RHCP)components of CVBs are independently modulated via spin-to-orbit interactions by the properly designed metasurface,and then simultaneously multiplexed and demultiplexed due to the reversibility of light path and the conservation of vector mode.We also show that the proposed multiplexers/demultiplexers are broadband(from 1310 to 1625 nm)and compatible with wavelength-division-multiplexing.As a proof of concept,we successfully demonstrate a four-channel CVB multiplexing communication,combining wavelength-division-multiplexing and polarization-division-multiplexing with a transmission rate of 1.56 Tbit/s and a bit-error-rate of 10^(−6) at the receive power of−21.6 dBm.This study paves the way for CVB multiplexing/demultiplexing and may benefit high-capacity CVB communication. | Shuqing Chen Zhiqiang Xie Huapeng Ye Xinrou Wang Zhenghao Guo Yanliang He Ying Li Xiaocong Yuan Dianyuan Fan | 2021 | Light(Science & Applications)2021，10，12： | 6 |
| 6 | Exogenous Melatonin Improves Physiological Characteristics and Promotes Growth of Strawberry Seedlings Under Cadmium Stress显示文摘Melatonin,as a plant growth regulator,is involved in plant stress resistance.We studied the effects of different concentrations(0,10,50,100,150,and 200μmol·L−1)of melatonin on the growth and physiological characteristics of strawberry under cadmium(Cd)stress.The results represented that the growth of strawberry seedlings was inhibited under Cd stress,and the seedling biomass,chlorophyll content and the activities of antioxidant enzymes such as superoxide dismutase(SOD),peroxidase(POD),catalase(CAT),and ascorbate peroxidase(APX)decreased.These toxic effects were,however,effectively remediated by exogenous melatonin pretreatment.Melatonin treatment slowed the inhibitory effect of seedling growth and significantly increased seedling biomass,chlorophyll content,antioxidant enzyme activities,and soluble protein levels in leaves and roots compared with the control.Melatonin treatment also reduced the malondialdehyde(MDA)content and the oxidative stress reactions,increased the anthocyanin content,and slowed the senescence rate,thereby reducing the toxic effects of Cd on strawberries.This indicates that foliar application of melatonin can effectively remediate the adverse effects of Cd on strawberry seedlings;the greatest effect was obtained with melatonin concentration of 100μmol·L−1. | Shuqing Wu Yao Wang Junkang Zhang Xiaojun Gong Zhen Zhang Jingjing Sun Xuesen Chen Yanling Wang | 2021 | Horticultural Plant Journal2021，7，1： | 6 |

| 8 | Orbital angular momentum mode logical operation using optical diffractive neural network显示文摘Optical logical operations demonstrate the key role of optical digital computing,which can perform general-purpose calculations and possess fast processing speed,low crosstalk,and high throughput.The logic states usually refer to linear momentums that are distinguished by intensity distributions,which blur the discrimination boundary and limit its sustainable applications.Here,we introduce orbital angular momentum(OAM)mode logical operations performed by optical diffractive neural networks(ODNNs).Using the OAM mode as a logic state not only can improve the parallel processing ability but also enhance the logic distinction and robustness of logical gates owing to the mode infinity and orthogonality.ODNN combining scalar diffraction theory and deep learning technology is designed to independently manipulate the mode and spatial position of multiple OAM modes,which allows for complex multilight modulation functions to respond to logic inputs.We show that few-layer ODNNs successfully implement the logical operations of AND,OR,NOT,NAND,and NOR in simulations.The logic units of XNOR and XOR are obtained by cascading the basic logical gates of AND,OR,and NOT,which can further constitute logical half-adder gates.Our demonstrations may provide a new avenue for optical logical operations and are expected to promote the practical application of optical digital computing. | PEIPEI WANG WENJIE XIONG ZEBIN HUANG YANLIANG HE ZHIQIANG XIE JUNMIN LIU HUAPENG YE YING LI DIANYUAN FAN SHUQING CHEN | 2021 | Photonics Research2021，9，10： | 5 |

| 10 | Far-field coseismic gravity changes related to the 2015 MW7.8 Nepal(Gorkha)earthquake observed by superconducting gravimeters in Chinese mainland显示文摘Using data from five SGs at four stations in Chinese mainland,obvious permanent gravity changes caused by the 2015 MW7.8 Nepal(Gorkha)earthquake were detected.We analyzed the gravity effects from ground vertical deformation(VD)using co-site continuous GPS(cGPS)data collocated at the Lijiang and the Wuhan station,and hydrological effects using GLDAS models and groundwater level records.After removing these effects,SG observations before and after the earthquake revealed obvious permanent gravity changes:−3.0μGal,7.3μGal and 8.0μGal at Lhasa,Lijiang and Wuhan station,respectively.We found that the gravity changes cannot be explained by the results of dislocation theory. | LeLin Xing ZiWei Liu JianGang Jia ShuQing Wu ZhengSong Chen XiaoWei Niu | 2021 | Earth and Planetary Physics2021，5，2： | 4 |
| 11 | High-resolution azimuth estimation algorithm based on data fusion method for the vector hydrophone vertical array显示文摘To aim at the problem that the horizontal directivity index of the vector hydrophone vertical array is not higher than that of a vector hydrophone,the high-resolution azimuth estimation algorithm based on the data fusion method was presented.The proposed algorithm first employs MUSIC algorithm to estimate the azimuth of each divided sub-band signal,and then the estimated azimuths of multiple hydrophones are processed by using the data fusion technique.The high-resolution estimated result is achieved finally by adopting the weighted histogram statistics method.The results of the simulation and sea trials indicated that the proposed algorithm has better azimuth estimation performance than MUSIC algorithm of a single vector hydrophone and the data fusion technique based on the acoustic energy flux method.The better performance is reflected in the aspects of the estimation precision,the probability of correct estimation,the capability to distinguish multi-objects and the inhibition of the noise sub-bands. | CHEN Yu MENG Zhou MA Shuqing BAO Changchun | 2015 | Chinese Journal of Acoustics2015，34，3： | 3 |
| 12 | Controllable photonic spin Hall effect with phase function construction显示文摘Photonic spin Hall efect(SHE)provides new opportunities for achieving spin-based photonics applications.However,flexibly manipulating the spin-dependent sltting(SDS)of photonic SHE and imposing extra phase modulation on the two spin components are always a challenge.Here,a controllable SHE mechanism based on phase function construction is reported.It is conduded that the phases with specific functional structures performing a coordinate translation are equivalent to integrating a gradient phase to the original phases.Hence,the original phase can be used for independent phase modulation,and the gradient phase originating from the co-ordinate translation is capable of manipulating the SDS.A metasurface with Pancharatnam-Berry phase that can impose conjugate phases to the two spin components of light is fabricated to verify this mechanism.By shifing the light position,the SDS is continuously manipulated in the visible region,which is successfully used for detecting the polarization llipticity.The extra phase modulation is also performed with the original phase and thus enables measuring singular beams.It is anticipated that the controllable SHE manipulation method may open new avenues in the fields of spin photonics,optical sensing,optical communications,etc. | YANLIANG HE ZHIQIANG XIE BO YANG XUEYU CHEN JUNMIN LIU HUAPENG YE XINXING ZHOU YING LI SHUQING CHEN DIANYUAN FAN | 2020 | Photonics Research2020，8，6： | 3 |
| 13 | IAP's Solar-Powered Unmanned Surface Vehicle Actively Passes through the Center of typhoon Sinlaku(2020)显示文摘The solar-powered marine unmanned surface vehicle(USV) developed by the USV team of the Institute of Atmospheric Physics is a rugged, long-duration, and autonomous navigation vessel designed for the collection of longrange, continuous, real-time, meteorological and oceanographic measurements, especially under extreme sea conditions(sea state 6–7). These solar-powered USVs completed a long-term continuous navigation observation test over 26 days.During this time, they coordinated double-USV observations and actively navigated into the path of Typhoon Sinlaku(2020) before collecting data very close to its center during the 2020 USV South China Sea Typhoon Observation Experiment. Detailed high temporal resolution(1 min) real-time observations collected by the USV on the typhoon were used for operational typhoon forecasting and warning for the first time. As a mobile meteorological and oceanographic observation station capable of reliable, automated deployment, data collection, and transmission, such solar-powered USVs can replace traditional observation platforms to provide valuable real-time data for research, forecasting, and early warnings for potential marine meteorological disasters. | Hongbin CHEN Jun LI Wenying HE Shuqing MA Yingzhi WEI Jidong PAN Yu ZHAO Xuefen ZHANG Shuzhen HU | 2021 | Advances in Atmospheric Sciences2021，38，4： | 2 |
| 14 | Methylesterification of cell-wall pectin controls the diurnal flower-opening times in rice显示文摘Flowers are the core reproductive organ of plants, and flowering is essential for cross-pollination. Diurnal flower-opening time is thus a key trait influencing reproductive isolation, hybrid breeding, and thermostability in plants. However, the molecular mechanisms controlling this trait remain unknown. Here, we report that rice Diurnal Flower Opening Time 1 (DFOT1) modulates pectin methylesterase (PME) activity to regulate pectin methylesterification levels of the lodicule cell walls, which affect lodicule swelling to control diurnal flower-opening time. DFOT1 is specifically expressed in the lodicules, and its expression gradually increases with the approach to flowering but decreases with flowering. Importantly, a knockout of DFOT1 showed earlier diurnal flower opening. We demonstrate that DFOT1 interacts directly with multiple PMEs to promote their activity. Knockout of PME40 also resulted in early diurnal flower opening, whereas overexpression of PME42 delayed diurnal flower opening. Lower PME activity was observed to be associated with higher levels of pectin methylesterification and the softening of cell walls in lodicules, which contribute to the absorption of water by lodicules and cause them to swell, thus promoting early diurnal flower opening. Higher PME activity had the opposite effect. Collectively, our work uncovers a molecular mechanism underlying the regulation of diurnal flower-opening time in rice, which would help reduce the costs of hybrid breeding and improve the heat tolerance of flowering plants by avoiding higher temperatures at anthesis. | Mumei Wang Xiaopei Zhu Guoqing Peng Minglong Liu Shuqing Zhang Minghao Chen Shitang Liao Xiaoying Wei Peng Xu Xiyu Tan Fangping Li Zhichuan Li Li Deng Ziliang Luo Liya Zhu Shuai Zhao Dagang Jiang Jing Li Zhenlan Liu Xianrong Xie Shaokui Wang Aimin Wu Chuxiong Zhuang Hai Zhou | 2022 | Molecular Plant2022，15，6： | 2 |
| 15 | A ubiquitous knowledgeable data representation model(UKRM) for three-dimensional geographic information systems(3D GIS)显示文摘In the face of complicated, diversified three-dimensional world, the existing 3D GIS data models suffer from certain issues such as data incompatibility, insufficiency in data representation and representation types, among others. It is often hard to meet the requirements of multiple application purposes(users) related to GIS spatial data management and data query and analysis, especially in the case of massive spatial objects. In this study, according to the habits of human thinking and recognition, discrete expressions(such as discrete curved surface(DCS), and discrete body(DB)) were integrated and two novel representation types(including function structure and mapping structure) were put forward. A flexible and extensible ubiquitous knowledgeable data representation model(UKRM) was then constructed, in which structurally heterogeneous multiple expressions(including boundary representation(B-rep), constructive solid geometry(CSG), functional/parameter representation, etc.) were normalized. GIS's ability in representing the massive, complicated and diversified 3D world was thus greatly enhanced. In addition, data reuse was realized, and the bridge linking static GIS to dynamic GIS was built up. Primary experimental results illustrated that UKRM was overwhelmingly superior to the current data models(e.g. IFC, City GML) in describing both regular and irregular spatial objects. | ZHANG ShuQing ZHOU ChengHu ZHANG JunYan CHEN XiangCong | 2016 | Science China Earth Sciences2016，59，4： | 2 |

| 17 | Comparative Osteology and Phylogenetic Relationship of Edmontosaurus and Shantungosaurus (Dinosauria:Hadrosauridae) from the Upper Cretaceous of North America and East Asia显示文摘The close affinity between Edmontosaurus and Shantungosaurus is corroborated on the basis of the following shared features:an occipital condyle deflected strongly posteroventrally; a posterodorsally reflected, lip-shaped oral margin of the premaxilla, with a deep, oval concavity at the anteromedial corner of the bone; a well-demarcated posterodorsal margin of the deeply excavated circumnarial fossa formed by a prominent arched ridge along the entire posterior half of the lateroventral border of the nasal; an anteroposteriorly broad jugal process of the postorbital; a strongly concave dorsal surface of the paired frontals; seven teeth per alveolus in the middle of the dentary tooth row; and a circular distal blade of the pubis that is much more expanded ventrally than dorsally. A revised phylogenetic analysis of Hadrosauroidea recovers a sister taxon relationship between Edmontosaurus and Shantungosaurus. Kerberosaurus is recovered as the sister taxon to the clade formed exclusively by these two genera. The clade Edmontosaurini could be defined as the least inclusive clade containing Kerberosaurus and Edmontosaurus, which is currently composed of the genera Kerberosaurus, Edmontosaurus, and Shantungosaurus. Zhuchengosaurus and Huaxiaosaurus,both from the Upper Cretaceous Wangshi Group in Zhucheng, are interpreted as junior synonyms of Shantungosaurus. Kundurosaurus is likewise considered a junior synonym of Kerberosaurus. The strict consensus tree together with biogeographic information indicates that the clade Edmontosaurini originated in Asia and subsequently dispersed into North America. | XING Hai ZHAO Xijin WANG Kebai LI Dunjing CHEN Shuqing Jordan C.MALLON ZHANG Yanxia XU Xing | 2014 | Acta Geologica Sinica(English Edition)2014，88，6： | 2 |
| 18 | TSNAdb: A Database for Tumor-specific Neoantigens from Immunogenomics Data Analysis显示文摘Tumor-specific neoantigens have attracted much attention since they can be used as biomarkers to predict therapeutic effects of immune checkpoint blockade therapy and as potential targets for cancer immunotherapy. In this study, we developed a comprehensive tumor-specific neoantigen database(TSNAdb v1.0), based on pan-cancer immunogenomic analyses of somatic mutation data and human leukocyte antigen(HLA) allele information for 16 tumor types with 7748 tumor samples from The Cancer Genome Atlas(TCGA) and The Cancer Immunome Atlas(TCIA). We predicted binding affinities between mutant/wild-type peptides and HLA class I molecules by NetMHCpan v2.8/v4.0, and presented detailed information of 3,707,562/1,146,961 potential neoantigens generated by somatic mutations of all tumor samples. Moreover, we employed recurrent mutations in combination with highly frequent HLA alleles to predict potential shared neoantigens across tumor patients,which would facilitate the discovery of putative targets for neoantigen-based cancer immunotherapy.TSNAdb is freely available at http://biopharm.zju.edu.cn/tsnadb. | Jingcheng Wu Wenyi Zhao Binbin Zhou Zhixi Su Xun Gu Zhan Zhou Shuqing Chen | 2018 | Genomics, Proteomics & Bioinformatics2018，16，4： | 2 |
| 19 | 1-Pbps orbital angular momentum fibre-optic transmission显示文摘Space-division multiplexing(SDM),as a main candidate for future ultra-high capacity fibre-optic communications,needs to address limitations to its scalability imposed by computation-intensive multi-input multi-output(MIMO)digital signal processing(DSP)required to eliminate the crosstalk caused by optical coupling between multiplexed spatial channels.By exploiting the unique propagation characteristics of orbital angular momentum(OAM)modes in ring core fibres(RCFs),a system that combines SDM and C+L band dense wavelength-division multiplexing(DWDM)in a 34 km 7-core RCF is demonstrated to transport a total of 24960 channels with a raw(net)capacity of 1.223(1.02)Peta-bit s−1(Pbps)and a spectral efficiency of 156.8(130.7)bit s−1 Hz−1.Remarkably for such a high channel count,the system only uses fixed-size 4×4 MIMO DSP modules with no more than 25 time-domain taps.Such ultra-low MIMO complexity is enabled by the simultaneous weak coupling among fibre cores and amongst non-degenerate OAM mode groups within each core that have a fixed number of 4 modes.These results take the capacity of OAM-based fibre-optic communications links over the 1 Pbps milestone for the first time.They also simultaneously represent the lowest MIMO complexity and the 2nd smallest fibre cladding diameter amongst reported few-mode multicore-fibre(FM-MCF)SDM systems of>1 Pbps capacity.We believe these results represent a major step forward in SDM transmission,as they manifest the significant potentials for further up-scaling the capacity per optical fibre whilst keeping MIMO processing to an ultra-low complexity level and in a modularly expandable fashion. | Junyi Liu Jingxing Zhang Jie Liu Zhenrui Lin Zhenhua Li Zhongzheng Lin Junwei Zhang Cong Huang Shuqi Mo Lei Shen Shuqing Lin Yujie Chen Ran Gao Lei Zhang Xiaobo Lan Xinlun Cai Zhaohui Li Siyuan Yu | 2022 | Light(Science & Applications)2022，11，8： | 1 |
| 20 | Experimental investigation of Z-pinch radiation source for indirect drive inertial confinement fusion显示文摘Z-pinch dynamic hohlraums(ZPDHs)could potentially be used to drive inertial confinement fusion targets.Double-or multishell capsules using the technique of volume ignition could exploit the advantages of ZPDHs while tolerating their radiation asymmetry,which would be unacceptable for a central ignition target.In this paper,we review research on Z-pinch implosions and ZPDHs for indirect drive targets at the Institute of Nuclear Physics and Chemistry,China Academy of Engineering Physics.The characteristics of double-shell targets and the associated technical requirements are analyzed through a one-dimensional computer code developed from MULTI-IFE.Some key issues regarding the establishment of suitable sources for dynamic hohlraums are introduced,such as soft X-ray power optimization,novel methods for plasma profile modulation,and the use of thin-shell liner implosions to inhibit the generation of prior-stagnated plasma.Finally,shock propagation and radiation characteristics in a ZPDH are presented and discussed,together with some plans for future work. | Zhenghong Li Zhen Wang Rongkun Xu Jianlun Yang Fan Ye Yanyun Chu Zeping Xu Faxin Chen Shijian Meng Jianmin Qi Qinyuan Hu Yi Qin Jiaming Ning Zhanchang Huang Linbo Li Shuqing Jiang | 2019 | Matter and Radiation at Extremes2019，4，4： | 1 |
