| 1 | Dynamical classification of topological quantum phases显示文摘Topological phase of matter is now a mainstream of research in condensed matter physics, of which the classification, synthesis, and detection of topological states have brought excitements over the recent decade while remain incomplete with ongoing challenges in both theory and experiment. Here we propose to establish a universal non-equilibrium characterization of the equilibrium topological quantum phases classified by integers, and further propose the high-precision dynamical schemes to detect such states. The framework of the dynamical classification theory consists of basic theorems. First, we uncover that classifying a d-dimensional(dD) gapped topological phase of generic multibands can reduce to a(d-1)D invariant defined on so-called band inversion surfaces(BISs), rendering a bulk-surface duality which simplifies the topological characterization. Further, we show in quenching across phase boundary the(pseudo) spin dynamics to exhibit unique topological patterns on BISs, which are attributed to the post-quench bulk topology and manifest a dynamical bulk-surface correspondence. For this the topological phase is classified by a dynamical topological invariant measured from an emergent dynamical spintexture field on the BISs. Applications to quenching experiments on feasible models are proposed and studied, demonstrating the new experimental strategies to detect topological phases with high feasibility. This work opens a broad new direction to classify and detect topological phases by non-equilibrium quantum dynamics. | Lin Zhang Long Zhang Sen Niu Xiong-Jun Liu | 2018 | Science Bulletin2018，63，21： | 9 |
| 2 | A Novel Green Preparation ofα,α′-Bis(substituted benzylidene)-cycloalkanones Promoted by FeCl3·6H2O in Ionic Liquid显示文摘α, α'-Bis(substituted benzylidene)cycloalkanones were efficiently prepared fromcycloalkanones and benzaldehydes in [bmim][BF4] by using iron(Ⅲ) chloride hexahydrate as acatalyst. It is shown that [bmim][BF4] and iron(Ⅲ) chloride hexahydrate can be quantitativelyrecovered and be reused effectively for many times. Compared with the known methods, thisnovel process has the advantage of being an environmentally benign process together with goodyields and mild reaction conditions. | Xin Ying ZHANG, Xue Sen FAN, Hong Ying NIU, Jian Ji WANGSchool of Chemical and Environmental Sciences, Henan Normal University, Key Laboratory ofEnvironmental Science and Engineering of Henan Education Department,Xinxiang 453002 | 2003 | Chinese Chemical Letters2003，14，10： | 5 |
| 3 | Integrin αvβ6 sustains and promotes tumor invasive growth in colon cancer progression显示文摘AIM: To detect the mechanism by which colon tumor escapes the growth constraints imposed on normal cells by cell crowding and dense pericellular matrices.METHODS: An immunohistochemical study of integrin αvβ6 and matrix metalloproteinase-9(MMP-9) was performed on tissue microarrays of 200 spots, including 100 cases of colon tumors. RESULTS: High immunoreactivity for αvβ6(73.7%; 28/38) and MMP-9(76.5%; 52/68) was observed in invasive tumor portions. Furthermore, the effects of integrin αvβ6 on tumor invasive growth in nude mice were detected. Tumor invasive growth and high expression of both αvβ6 and MMP-9 were only seen in tumors resulting from Wi Dr cells expressing αvβ6 in the tumorigenicity assay. Flow cytometry was applied to analyze αvβ6 expression in colon cancer Wi Dr and SW480 cells. The effects of cell density on αvβ6 expression and MMP-9 secretion were also detected by Biotrak MMP-9 activity assay and gelatin zymography assay. High cell density evidently enhanced αvβ6 expression and promoted MMP-9 secretion compared with low density. CONCLUSION: Integrin αvβ6 sustains and promotes tumor invasive growth in tumor progression via a selfperpetuating mechanism. Integrin ανβ6-mediated MMP-9 secretion facilitates pericellular matrix degradation at high cell density, which provides the basis of invasive growth. | Guang-Yun Yang Sen Guo Cong-Ying Dong Xian-Qiang Wang Bing-Yang Hu Yang-Feng Liu Yong-Wei Chen Jun Niu Jia-Hong Dong | 2015 | World Journal of Gastroenterology2015，21，24： | 3 |
| 4 | An Improved Algorithm of Grounding Grids Corrosion Diagnosis Based on Total Least Square Method显示文摘A new model considering corrosion property for grounding grids diagnosis is proposed,which provides reference solutions of ambiguous branches.The constraint total least square method based on singular value decomposition is adopted to improve the effectiveness of grounding grids' diagnosis algorithm.The improvement can weaken the influence of the model's error,which results from the differences between design paper and actual grid.Its influence on touch and step voltages caused by the interior resistance of conductors is taken into account.Simulation results show the validity of this approach. | ZHANG Ying-jiao NIU Tao WANG Sen | 2011 | 高压电器2011，47，5： | 3 |
| 5 | Microstructural adjustments and mechanical properties of a cold-rolled biomedical near β-Ti alloy sheet显示文摘In this study, microstructural adjustments and mechanical properties of a cold-rolled nearβ-type alloy Ti-25Nb-3Zr-3Mo-2Sn (wt%) sheet were investigated.Microstructures and phase transformation products strongly depended on aging temperatures. Solution treatments within singleβ-phase field removed the stress-inducedα″martensites and produced a few new lath-shaped ones, but metastableβphase still dominated. This is exactly the reason why current alloy exhibits the lowest modulus (54 GPa) and best elongation to fracture (39%),but the worst yield strength of only 340 MPa, at solutiontreated state. A fairly large number of ellipsoidalωphase nanoparticles precipitated throughout parentβphase during aging at 380℃. Theseωnanoparticles possess remarkable strengthening effect, but deteriorate ductility seriously. A novel post-aging process was proposed to remove brittleωphase. By contrast, aging at 450℃resulted in sufficient precipitation of fine needle-like a phase. This brought about the best combination of high yield strength (770 MPa) and moderate elastic modulus(75 GPa) and good elongation (15%) for biomedical implants. | Xi-Qun Ma Hong-Zhi Niu Zhen-Tao Yu Sen Yu Chang Wang | 2018 | Rare Metals2018，37，10： | 3 |
| 6 | Exome sequencing reveals genetic architecture in patients with isolated or syndromic short stature显示文摘Short stature is among the most common endocrinological disease phenotypes of childhood and may occur as an isolated finding or in conjunction with other clinical manifestations.Although the diagnostic utility of clinical genetic testing in short stature has been implicated,the genetic architecture and the utility of genomic studies such as exome sequencing(ES)in a sizable cohort of patients with short stature have not been investigated systematically.In this study,we recruited 561 individuals with short stature from two centers in China during a 4-year period.We performed ES for all patients and available parents.All patients were retrospectively divided into two groups:an isolated short stature group(group I,n=257)and an apparently syndromic short stature group(group II,n=304).Causal variants were identified in 135 of 561(24.1%)patients.In group I,29 of 257(11.3%)of the patients were solved by variants in 24 genes.In group II,106 of 304(34.9%)patients were solved by variants in 57 genes.Genes involved in fundamental cellularprocess played an important role in the genetic architecture of syndromic short stature.Distinct genetic architectures and pathophysiological processes underlie isolated and syndromic short stature. | Xin Fan Sen Zhao Chenxi Yu Di Wu Zihui Yan Lijun Fan Yanning Song Yi Wang Chuan Li Yue Ming Baoheng Gui Yuchen Niu Xiaoxin Li Xinzhuang Yang Shiyu Luo Qiang Zhang Xiuli Zhao Hui Pan Mei Li Weibo Xia Guixing Qiu Pengfei Liu Shuyang Zhang Jianguo Zhang Zhihong Wu James R.Lupski Jennifer E.Posey Shaoke Chen Chunxiu Gong Nan Wu | 2021 | Journal of Genetics and Genomics2021，48，5： | 2 |
| 7 | Unsourced Multiple Access for 6G Massive Machine Type Communications显示文摘Unsourced multiple access(UMA)is a multi-access technology for massive,low-power,uncoordinated,and unsourced Machine Type Communication(MTC)networks.It ensures transmission reliability under the premise of high energy efficiency.Based on the analysis of the 6G MTC key performance indicators(KPIs)and scenario characteristics,this paper summarizes its requirements for radio access networks.Following this,the existing multiple access models are analyzed under these standards to determine UMA's advantages for 6G MTC according to its design characteristics.The critical technology of UMA is the design of its multiple-access coding scheme.Therefore,the existing UMA coding schemes from different coding paradigms are further summarized and compared.In particular,this paper comprehensively considers the energy efficiency and computational complexity of these schemes,studies the changes of the above two indexes with the increase of access scale,and considers the trade-off between the two.It is revealed by the above analysis that some guiding rules of UMA coding design.Finally,the open problems and potentials in this field are given for future research. | Yuanjie Li Jincheng Dai Zhongwei Si Kai Niu Chao Dong Jiaru Lin Sen Wang Yifei Yuan | 2022 | China Communications2022，19，3： | 2 |
| 8 | Joint Source-Channel Coding for 6G Communications显示文摘In order to provide ultra low-latency and high energy-efficient communication for intelligences,the sixth generation(6G)wireless communication networks need to break out of the dilemma of the depleting gain of the separated optimization paradigm.In this context,this paper provides a comprehensive tutorial that overview how joint source-channel coding(JSCC)can be employed for improving overall system performance.For the purpose,we first introduce the communication requirements and performance metrics for 6G.Then,we provide an overview of the source-channel separation theorem and why it may not hold in practical applications.In addition,we focus on two new JSCC schemes called the double low-density parity-check(LDPC)codes and the double polar codes,respectively,giving their detailed coding and decoding processes and corresponding performance simulations.In a nutshell,this paper constitutes a tutorial on the JSCC scheme tailored to the needs of future 6G communications. | Yanfei Dong Jincheng Dai Kai Niu Sen Wang Yifei Yuan | 2022 | China Communications2022，19，3： | 2 |

| 12 | Development of branchless watermelon near isogenic lines by marker assisted selection显示文摘Pruning is time-consuming and laborious in watermelon cultivation,which can not meet the needs for simplified cultivation in the future.The development of branchless lines will provide important germplasms for breeding watermelon varieties and is an important method for genetic improvement.In this study,the watermelon accession,Wu Cha Zao(WCZ)is a branchless inbred line that carries the branchless gene Clbl,which was used as the donor parent to develop branchless near isogenic lines(NILs).To construct the NILs of Clbl,WCZ crossed with the normal branching watermelon inbred line WT20 which was used as the recurrent parent.The co-segregating markers dCAPS10 and Indel1 with Clbl were used for foreground selection,and a total of 108 SSR markers was selected with good polymorphism between two parental lines for background selection which had relatively uniform distribution across 11 chromosomes.Using these markers to select individuals from the BC_(1)F_(1),BC_(2)F_(1),and BC_(2)F_(2) generations,three NILs with a proportion of recurrent parent genome(PRPG)>99%were finally obtained.The lateral branch and plant height phenotypes did not significantly differ between the NILs and WCZ,indicating that the NILs of Clbl under the genetic background of WT20 has been successfully developed.These results provide ideal materials for further in-depth analysis of the genetic mechanisms of lateral branch development and ideal plant architecture breeding in watermelon. | Junling Dou Yinping Wang Huihui Yang Huanhuan Niu Dongming Liu Sen Yang Huayu Zhu Shouru Sun Luming Yang | 2022 | Horticultural Plant Journal2022，8，5： | 1 |

| 14 | HD-Zip Transcription Factor is Responsible for No-Lobed Leaf in Watermelon(Citrullus lanatus L.)显示文摘Leaf is a vital organ of plants that plays an essential role in photosynthesis and respiration.As an important agronomic trait in leaf development,leaf shape is classified into lobed,entire(no-lobed),and serrated in most crops.In this study,two-lobed leaf watermelon inbred lines WT2 and WCZ,and a no-lobed leaf watermelon inbred line WT20 were used to create two F_(2)populations.Segregation analysis suggested that lobed leaves were dominant over the no-lobed leaves,and it was controlled by a signal gene.A locus on watermelon chromosome 4 controlling watermelon lobed/no-lobed leaves was identified through BSA-seq strategy combined with linkage analysis.The candidate gene was fine-mapped to a 61.5 kb region between 21,224,481 and 21,285,957 bp on watermelon chromosome 4 using two F_(2)populations.Four functional genes were annotated in the candidate region,while sequences blast showed that there was a single-base deletion(A/-)only in the exon of Cla018360,which resulted in premature termination of translation in the no-lobed leaf lines.Function prediction showed that Cla018360 encodes an HD-Zip protein that has been reported to regulate the development of leaf shape.The single-base deletion also occurred in the HD-Zip domain.We inferred that the Cla018360 gene is the candidate gene for regulating the development of lobed/no-lobed leaves in watermelon.Gene expression analysis showed that Cla018360 was highly expressed in young leaves.Phylogenetic analysis showed that Cla018360 had a close genetic relationship with AtHB51,which had been reported to regulate the formation of leaf shape in Arabidopsis.Furthermore,transcriptome analysis showed that a total of 333 differentially expressed genes were identified between WT2 and WT20,of which 115 and 218 genes were upregulated and downregulated in no-lobed leaved watermelon WT20.This study not only provides a good entry point for studying leaf development but also provides foundational insights into breeding for special plant architecture in watermelon. | Shixiang Duan Yaomiao Guo Yinping Wang Muhammad Jawad Umer Dongming Liu Sen Yang Huanhuan Niu Shouru Sun Luming Yang Junling Dou Huayu Zhu | 2023 | Phyton-International Journal of Experimental Botany2023，92，5： | 1 |

| 19 | A Novel Evaluation Strategy to Artificial Neural Network Model Based on Bionics显示文摘With the continuous deepening of Artificial Neural Network(ANN)research,ANN model structure and function are improving towards diversification and intelligence.However,the model is more evaluated from the pros and cons of the problem-solving results and the lack of evaluation from the biomimetic aspect of imitating neural networks is not inclusive enough.Hence,a new ANN models evaluation strategy is proposed from the perspective of bionics in response to this problem in the paper.Firstly,four classical neural network models are illustrated:Back Propagation(BP)network,Deep Belief Network(DBN),LeNet5 network,and olfactory bionic model(KIII model),and the neuron transmission mode and equation,network structure,and weight updating principle of the models are analyzed qualitatively.The analysis results show that the KIII model comes closer to the actual biological nervous system compared with other models,and the LeNet5 network simulates the nervous system in depth.Secondly,evaluation indexes of ANN are constructed from the perspective of bionics in this paper:small-world,synchronous,and chaotic characteristics.Finally,the network model is quantitatively analyzed by evaluation indexes from the perspective of bionics.The experimental results show that the DBN network,LeNet5 network,and BP network have synchronous characteristics.And the DBN network and LeNet5 network have certain chaotic characteristics,but there is still a certain distance between the three classical neural networks and actual biological neural networks.The KIII model has certain small-world characteristics in structure,and its network also exhibits synchronization characteristics and chaotic characteristics.Compared with the DBN network,LeNet5 network,and the BP network,the KIII model is closer to the real biological neural network. | Sen Tian Jin Zhang Xuanyu Shu Lingyu Chen Xin Niu You Wang | 2022 | Journal of Bionic Engineering2022，19，1： | 0 |
| 20 | Coverage and capacity optimization in LTE network based on non-cooperative games显示文摘As to provide the optimal coverage and capacity performance,support high-data-rate service and decrease the capital expenditures and operational expenditures(OPEX)(CAPEX) for operator,the coverage and capacity optimization(CCO) is one of the key use cases in long term evolution(LTE) self-organization network(SON).In LTE system,some factors(e.g.load,traffic type,user distribution,uplink power setting,inter-cell interference,etc.) limit the coverage and capacity performance.From the view of single cell,it always pursuits maximize performance of coverage and capacity by optimizing the uplink power setting and intra-cell resource allocation,but it may result in decreasing the performance of its neighbor cells.Therefore,the benefit of every cell conflicts each other.In order to tradeoff the benefit of every cell and maximize the performance of the whole network,this paper proposes a multi-cell uplink power allocation scheme based on non-cooperative games.The scheme aims to make the performance of coverage and capacity balanced by the negotiation of the uplink power parameters among multi-cells.So the performance of every cell can reach the Nash equilibrium,making it feasible to reduce the inter-cell interference by setting an appropriate uplink power parameter.Finally,the simulation result shows the proposed algorithm can effectively enhance the performance of coverage and capacity in LTE network. | XU Sen HOU Meng NIU Kai HE Zhi-qiang WU Wei-ling | 2012 | The Journal of China Universities of Posts and Telecommunications2012，19，4： | 0 |
