| 2 | Geochemical characteristics of the metapelites from the Xingxingxia group in the Eastern Segment of the Central Tianshan:Implications for the provenance and paleoweathering显示文摘Metapelites from the Mesoproterozoic Xingxingxia group in the Eastern Segment of the Central Tianshan, Northwestern China, were analyzed for major and trace elements, includ-ing rare earth elements. Compared with post-Archean shales, the metapelites are enriched in Sr, Hf and Zr. The other elements are similar to the compositions of the Phanerozoic North American Shale Composite and the Post-Archean Australian average Shale (PAAS). The characteristics of Al2O3/TiO2, Cr/Zr, Cr/Th, Th/Sc and high Zr concentration suggest that these pelites could be derived from a significant proportion of felsic and a few proportion of participation of mafic mate-rials in nature. These rocks display highly fractionated REE patterns, and average (La/Yb)n = 18.6. Several samples have slightly negative Eu anomalies (Eu/Eu* = 0.7―0.84) in comparison with PAAS (Eu/Eu* = 0.65), indicating contribution from young immature materials. The low K2O/Al2O3 values of these metapelites suggest that their source materials could contain minimal alkali feldspar. In the A-CN-K triangular diagram, the sample data array intersects the feldspar join, indicating that the source had a plagioclase: K-feldspar ratio of approximately 5:1, repre-senting weathered products from components that could approximately correspond to granodio-rites and tonalites. The low Chemical Index of Alteration (CIA) and high Index of Compositional Variability (ICV) values suggest low degrees of weathering of the source and low compositional maturity of the sediments, respectively. The geochemical characteristics of the metapelites from the Xingxingxia group also demonstrate that these sediments were deposited in a back-arc background within a continental-arc system. | LI Qiugen LIU Shuwen HAN Baofu WANG Yueran DANG Qingning | 2005 | Science China Earth Sciences2005，48，10： | 4 |

| 8 | Dual-Ion Co-Regulation System Enabling High-Performance Electrochemical Artificial Yarn Muscles with Energy-Free Catch States显示文摘Artificial yarn muscles show great potential in applications requiring low-energy consumption while maintaining high performance. However, conventional designs have been limited by weak ion-yarn muscle interactions and inefficient “rocking-chair” ion migration. To address these limitations, we present an electrochemical artificial yarn muscle design driven by a dual-ion co-regulation system. By utilizing two reaction channels, this system shortens ion migration pathways, leading to faster and more efficient actuation. During the charging/discharging process, PF_6~- ions react with carbon nanotube yarn, while Li~+ ions react with an Al foil. The intercalation reaction between PF_6~- and collapsed carbon nanotubes allows the yarn muscle to achieve an energy-free high-tension catch state. The dual-ion coordinated yarn muscles exhibit superior contractile stroke, maximum contractile rate, and maximum power densities, exceeding those of “rocking-chair” type ion migration yarn muscles. The dual-ion co-regulation system enhances the ion migration rate during actuation, resulting in improved performance. Moreover, the yarn muscles can withstand high levels of isometric stress, displaying a stress of 61 times that of skeletal muscles and 8 times that of “rocking-chair” type yarn muscles at higher frequencies. This technology holds significant potential for various applications, including prosthetics and robotics. | Ming Ren Lizhong Dong Xiaobo Wang Yuxin Li Yueran Zhao Bo Cui Guang Yang Wei Li Xiaojie Yuan Tao Zhou Panpan Xu Xiaona Wang Jiangtao Di Qingwen Li | 2023 | Nano-Micro Letters2023，15，10： | 1 |
| 9 | RBM46 is essential for gametogenesis and functions in post-transcriptional roles affecting meiotic cohesin subunits显示文摘RBM46 is a germ cell-specific RNA-binding protein required for gametogenesis,but the targets and molecular functions of RBM46 remain unknown.Here,we demonstrate that RBM46 binds at specific motifs in the 3'UTRs of mRNAs encoding multiple meiotic cohesin subunits and show that RBM46 is required for normal synaptonemal complex formation during meiosis initiation.Using a recently reported,high-resolution technique known as LACE-seq and working with low-input cells,we profiled the targets of RBM46 at single-nucleotide resolution in leptotene and zygotene stage gametes.We found that RBM46 preferentially binds target mRNAs containing GCCUAU/GUUCGA motifs in their 3'UTRs regions.In Rbm46 knockout mice,the RBM46-target cohesin subunits displayed unaltered mRNA levels but had reduced translation,resulting in the failed assembly of axial elements,synapsis disruption,and meiotic arrest.Our study thus provides mechanistic insights into the molecular functions of RBM46 in gametogenesis and illustrates the power of LACE-seq for investigations of RNA-binding protein functions when working with low-abundance input materials. | Yue Lv Gang Lu Yuling Cai Ruibao Su Liang Liang Xin Wang Wenyu Mu Xiuqing He Tao Huang Jinlong Ma Yueran Zhao Zi-Jiang Chen Yuanchao Xue Hongbin Liu Wai-Yee Chan | 2023 | Protein & Cell2023，14，1： | 0 |
| 10 | Optimized operation scheme of flash-memory-based neural network online training with ultra-high endurance显示文摘With the rapid development of machine learning,the demand for high-efficient computing becomes more and more urgent.To break the bottleneck of the traditional Von Neumann architecture,computing-in-memory(CIM)has attracted increasing attention in recent years.In this work,to provide a feasible CIM solution for the large-scale neural networks(NN)requiring continuous weight updating in online training,a flash-based computing-in-memory with high endurance(10^(9) cycles)and ultrafast programming speed is investigated.On the one hand,the proposed programming scheme of channel hot electron injection(CHEI)and hot hole injection(HHI)demonstrate high linearity,symmetric potentiation,and a depression process,which help to improve the training speed and accuracy.On the other hand,the low-damage programming scheme and memory window(MW)optimizations can suppress cell degradation effectively with improved computing accuracy.Even after 109 cycles,the leakage current(I_(off))of cells remains sub-10pA,ensuring the large-scale computing ability of memory.Further characterizations are done on read disturb to demonstrate its robust reliabilities.By processing CIFAR-10 tasks,it is evident that~90%accuracy can be achieved after 109 cycles in both ResNet50 and VGG16 NN.Our results suggest that flash-based CIM has great potential to overcome the limitations of traditional Von Neumann architectures and enable high-performance NN online training,which pave the way for further development of artificial intelligence(AI)accelerators. | Yang Feng Zhaohui Sun Yueran Qi Xuepeng Zhan Junyu Zhang Jing Liu Masaharu Kobayashi Jixuan Wu Jiezhi Chen | 2024 | Journal of Semiconductors2024，45，1： | 0 |
| 11 | Near-threshold-voltage operation in flash-based high-precision computing-in-memory to implement Poisson image editing显示文摘We propose a NOR flash-based computing-in-memory(CIM)to implement high-precision(32-bit)Poisson image editing,including the gradient operations and Laplace operation.To meet the requirements of image processing,CIM operation schemes and reliabilities are carefully studied and optimized,showing that the power consumption at the near-threshold-voltage(NTV)region can be as low as 40 fJ/bit,which is two orders lower than working at the saturation region.High-temperature retention,as well as various disturbs,are also analyzed.The proposed CIM scheme can be applied as an energy-efficient approach to construct the high-precision image processing accelerator. | Yang FENG Bing CHEN Mingfeng TANG Yueran QI Maoying BAI Chengcheng WANG Hai WANG Xuepeng ZHAN Junyu ZHANG Jing LIU Jixuan WU Jiezhi CHEN | 2023 | Science China(Information Sciences)2023，66，12： | 0 |
| 12 | Revealing the interlaminar shear failure behavior of unidirectional laminate under combined compression-shear loads显示文摘Due to the coupling effects between stresses in different directions,the mechanical behavior of an ad-vanced composite material under multiaxial loading is extremely complex.In this study,the influence of through-thickness compressive stress on the interlaminar shear performance of a carbon fiber-reinforced composite was experimentally investigated.Hollow cylindrical unidirectional laminate specimens were fabricated to conduct combined compression-shear tests,and the fracture morphologies of the specimens were characterized to reveal their failure behavior.The results indicate that a moderate compression load significantly enhanced the shear properties of the laminate by inhibiting crack propagation and improv-ing the friction effect.The shear strength and modulus of a laminate specimen subjected to combined stresses improved up to a maximum of 76%and 231%,respectively,over those of an equivalent specimen subjected to pure shear.However,as the applied through-thickness load approached the compressive strength of the laminate,the specimen shear capacity began to decline owing to the transition of frac-ture mechanisms.Indeed,the specimens exhibited mixed failure modes corresponding to the different stress states,which were induced by the combined effects of through-thickness compressive and shear stresses.As the applied through-thickness compressive stress increased,the dominant failure mode of the laminate specimen changed from fiber-matrix debonding to fiber shearing and then to fiber break-age,resulting in various shear performances. | Yueran Zhao Jian Zang Ben Jia Junchao Yang Xiaopeng Wan Wenzhi Wang Xiangming Chen | 2023 | Journal of Materials Science & Technology2023，，26： | 0 |
| 13 | bZIP Transcription Factor UvATF21 Mediates Vegetative Growth,Conidiation,Stress Tolerance and Is Required for Full Virulence of Rice False Smut Fungus Ustilaginoidea virens显示文摘bZIP proteins are widely distributed in eukaryotic organisms and regulate a diverse range of physiological processes.Several bZIP proteins have previously been identified in Ustilaginoidea virens.However,the biological roles of these bZIP proteins in this pathogen are still unknown.Here,one of these bZIP protein coding genes,UvATF21,was functionally characterized.Targeted deletion of UvATF21resulted in reduced conidiation and pathogenicity despite of the increased vegetative growth.The deletion mutants also significantly decreased the sensitivity to osmotic and oxidative stresses.Interestingly,deletion of UvATF21 exhibited different performances to cell wall integrity stress.These results indicated that UvATF21 played crucial roles in vegetative growth,conidiation,stress response,and full virulence in U.virens. | LIU Yueran QU Jinsong WANG Yufu YIN Weixiao LUO Chaoxi | 2023 | Rice science2023，30，1： | 0 |
| 14 | Design,Preparation and Properties of Bio-inspired Hierarchical Structure Yarns with Enhanced Thermal Insulation and Water Transfer Ability显示文摘Encouraged by the porous and stable structure of cold-resist animals’hair or feather,bio-inspired hierarchical structure yarns combining polyacrylonitrile(PAN)nanofibers and polypropylene(PP)hollow microfibers have been developed by a modified conjugate electrospinning technology.Physical cross-linking has been built to increase fibers adhesion and construct interlayer support for nanofibrous assembly.The nanofibers and hollow microfibers construct a stable porous structure with porosity of 62%,providing excellent thermal insulating ability[temperature difference(|ΔT|)between skin and yarn surface is 4.9℃]as well as good mechanical property.More interestingly,the water transfer ability(infiltrate the yarn in 10 s)of synthetic fibers has been improved greatly by the combination of thin diameter nanofibers to the yarn.It is believed that the research lays the foundation for bio-inspired engineering technology in the manufacture of thermal comfort. | JIA Yueran GONG Shun ZHANG Shu ZHAO Shikun QIN Zhen PAN Kai | 2021 | Chemical Research in Chinese Universities2021，37，3： | 0 |
| 15 | Geometrical Characterizations of Non-Radiating Sources at Polyhedral and Conical Corners with Applications显示文摘Considering the acoustic source scattering problems,when the sour-ce is non-radiating/invisible,we investigate the geometrical characterization for the underlying sources at polyhedral and conical corner.It is revealed that the non-radiating source with Holder continuous regularity must vanish at the corner.Using this kind of geometrical characterization of non-radiating sources,we establish local and global unique determination for a source with the polyhedral or corona shape support by a single far field measurement.Uniqueness by a single far field measurement constitutes of a long standing problem in inverse scattering problems. | Huaian Diao Yueran Geng Hongyu Liu Qinghua Yu | 2023 | Communications in Mathematical Research2023，39，4： | 0 |
| 16 | High‑Temperature‑Tolerant Artificial Muscles Using Poly(p‑phenylene benzobisoxazole)Composite Yarns显示文摘Today the developed yarn muscles or actuators still cannot satisfy the requirements of working in high-temperature environ-ments.Thermal resistivity is highly needed in aerospace and industrial protection applications.Herein,an artificial muscle with high-temperature tolerance is prepared using carbon nanotube(CNT)wrapped poly(p-phenylene benzobisoxazole)(PBO)composite yarns.A thermal twisting method was utilized to reorientate the stiff PBO molecular chains into a uniform and twist-stable coiled structure.The CNT/PBO composite yarn muscle generates reversible contractile strokes up to 18.9%under 5.4 MPa tension and outputs 1.3 kJ kg^(-1) energy density.In contrast to previous actuators,which are normally oper-ated at room temperatures,the CNT/PBO composite yarn muscles can work at ambient temperatures up to 300℃ with high contractile stroke and long-term stability.A bionic inchworm robot,a deployable structure,and smart textiles driven by the high-temperature-tolerant yarn muscles were demonstrated,showing the promise as a soft actuator towards high-temperature environment applications. | Jianfeng He Ming Ren Lizhong Dong Yulian Wang Xulin Wei Bo Cui Yulong Wu Yueran Zhao Jiangtao Di Qingwen Li | 2022 | Advanced Fiber Materials2022，4，5： | 0 |
| 17 | Foliar application of chelated sugar alcohol calcium fertilizer for regulating the growth and quality of wine grapes显示文摘The eastern foothills of Helan Mountain are a production area of high-quality wine grapes,but the low content of water-soluble calcium in the alkaline soil in this area has become an important limiting factor for the production of high-end wines.In this study,7-year-old Cabernet Sauvignon grapes grown at Lilan Winery,which is located at the eastern foot of Helan Mountain in Ningxia,China,were used to examine the effect of exogenous calcium supplementation on fruit growth and berry quality.Calcium sugar alcohol was applied as a foliar spray at 1.2 L/hm^(2)(T1),2.4 L/hm^(2)(T2),3.6 L/hm^(2)(T3),4.8 L/hm^(2)(T4),and 6.0 L/hm^(2)(T5)concentrations at the fruit expansion stage,the early stage of grape veraison,the middle stage of grape veraison,and the later stage of grape veraison.Water control was used for comparison.The results showed that foliar calcium supplementation can significantly enhance the photosynthetic characteristics of wine grape leaves,increase the chlorophyll content of leaves,and improve the quality of grape berries.Under the T3(3.6 L/hm^(2))concentration of exogenous calcium,the transverse diameter,the longitudinal diameter,and fruit shape index of grapes were the highest,which were increased by 1.71%,5.33%,and 3.92%compared to the control,respectively.The application of high calcium concentrations(T4 and T5)inhibited the physiological development of grapes.The spike length,hundred-grain weight,yield of wine grapes,sugar-acid ratio,tannin,and total phenols were the highest in the T2(2.4 L/hm^(2))treatment.The results of principal component analysis based on multiple indicators showed that foliar application of 2.4-3.6 L/hm^(2)chelated sugar alcohol calcium on the leaf surfaces of grape leaves was the most suitable for improving the physiological characteristics and berry quality of wine grapes. | Tinghui Ma Yueran Hui Li Zhang Baofeng Su Rui Wang | 2022 | International Journal of Agricultural and Biological Engineering2022，15，3： | 0 |
