| 1 | Identification and gene mapping of a narrow and upper-albino leaf mutant in rice(Oryza sativa L.)显示文摘The leaf blade consists of color and shape traits.Studies of leaf-blade development are important for improvement of rice yield and quality because it is an essential organ for photosynthesis.A narrow and upper-albino leaf mutant(nul1) was identified from among progeny of the indica restorer line Jinhui10 raised from seeds treated with ethyl methane sulfonate.Under field conditions,the mutant displayed narrow and upper-albino leaf blades with significantly decreased photosynthetic pigment contents throughout their development.The narrow-leaf trait is caused by a decreased number of small veins.In contrast to the wild type,the growth period was extended by approximately 8 d and agronomic traits,such as effective panicle number,percentage seed set and 1000-grain weight,declined significantly in the nul1 mutant.Genetic analysis suggested that the narrow and upper-albino leaf characteristics showed coseparation and were controlled by one recessive gene.The Nul1 gene was mapped onto chromosome 7 between the Indel marker Ind07-1 and the Simple Sequence Repeat marker RM21637.The physical distance between the markers was 75 kb and eight genes were annotated in this region based on the rice Nipponbare genome sequence.These results provide a foundation for cloning and function analysis of Nul1. | WANG Feng TANG YanQiang MIAO RunLong XU FangFang LIN TingTing HE GuangHua SANG XianChun | 2012 | Chinese Science Bulletin2012，57，28： | 4 |
| 2 | Assessment of strong earthquake risk in the Chinese mainland from 2021 to 2030显示文摘The long-term earthquake prediction from 2021 to 2030 is carried out by researching the active tectonic block boundary zones in the Chinese mainland.Based on the strong earthquake recurrence model,the cumulative probability of each target fault in the next 10 years is given by the recurrence period and elapsed time of each fault,which are adopted from relevant studies such as seismological geology,geodesy,and historical earthquake records.Based on the long-term predictions of large earthquakes throughout the world,this paper proposes a comprehensive judgment scheme based on the fault segments with the seismic gap,motion strongly locked,sparse small-moderate earthquakes,and apparent Coulomb stress increase.This paper presents a comprehensive analysis of the relative risk for strong earthquakes that may occur in the coming 10 years on the major faults in the active tectonic block boundary zones in the Chinese mainland.The present loading rate of each fault is first constrained by geodetic observations;the cumulative displacement of each fault is then estimated by the elapsed time since the most recent strong earthquake. | Zhigang Shao Yanqiang Wu Lingyun Ji Faqi Diao Fuqiang Shi Yujiang Li Feng Long Hui Zhang Wuxing Wang Wenxin Wei Peng Wang Xiaoxia Liu Qi Liu Zhengyang Pan Xiaofei Yin Yue Liu Wei Feng Zhenyu Zou Jia Cheng Renqi Lu Yueren Xu Xi Li | 2023 | Earthquake Research Advances2023，3，1： | 2 |

| 5 | Inverted duplication including Endothelin 3 closely related to dermal hyperpigmentation in Silkie chickens显示文摘The dermal hyperpigmentation phenotype in chickens is controlled by the dominant fibromelanosis allele.One of the ten unique characteristics of Silkie chickens is the fibromelanosis phenotype,which is pigmentation in the dermal layer of the skin and connective tissue.In this study,we found a mutation of fibromelanosis,a genomic rearrangement that included an inverted duplication of endothelin3(EDN3),is responsible.We show that,as a stimulator of melanoblast proliferation,EDN3 expression was increased in silkie embryos and in both skin and muscle throughout adulthood.EDN3 expression led to an increase in expression of the downstream genes EDNRB2 and TYRP2,and was closely relate with the hyperpigmentation phenotype.We examined eight different Chinese chicken breeds showing hyperpigmentation and conclude that this structural genetic variant exists in all fibromelanosis chicken breeds. | Ming TIAN Suyun FANG Yanqiang WANG Xiaorong GU Chungang FENG Rui HAO Xiaoxiang HU Ning LI | 2014 | Frontiers of Agricultural Science and Engineering2014，1，2： | 1 |
| 6 | Incorporation ofγ-aminobutyric acid and cesium cations to formamidinium lead halide perovskites for highly efficient solar cells显示文摘The stability issue has become one of the main challenges for the commercialization of perovskite solar cells(PSCs).Formamidinium(FA)-based perovskites have shown great promise owing to their improved thermal and moisture stability.However,these perovskites are suffering from phase transition and separation.Here,a method of incorporating of γ-aminobutyric acid(GABA) and cesium cations into FAPbl_(3) is developed to improve the phase stability.It is demonstrated that the crystallinity of α-FAPbl_(3) phase is greatly improved and the phase transition temperature is significantly dropped.The resultant solar cell therefore obtains a champion power conversion efficiency(PCE) of 23.71%,which is one of the highest efficiencies for methylammonium-free PSCs.Furthermore,it shows an impressively enhanced stability under illumination,exhibiting the great potential of FA-based perovskites for efficient and stable solar cells. | Yanqiang Hu Yansu Shan Zhaolei Yu Haojie Sui Ting Qiu Shufang Zhang Wei Ruan Qinfeng Xu Mengmeng Jiao Dehua Wang Yunyi Wu Chuanlu Yang Feng Xu | 2022 | Journal of Energy Chemistry2022，31，1： | 1 |
| 7 | Discrepancy of the magnetic behaviors and crystalline structure on the Co/FeMn and FeMn/Co interfaces with ultrathin Pt spacer显示文摘The exchange coupling at the ferromagnetic/antiferromagnetic(FM/AFM) interface is influenced by both the magnetic structure and the crystalline micro-structure.Co/FeMn/Co thin films with 0.4 nm Pt spacer layer inserted into the Co/FeMn and FeMn/Co interface respectively were deposited by means of magnetron sputtering.The two interfaces upon and beneath the FeMn layer show distinct behaviors before and after the Pt spacer inserted.There is a remarkable shrink of the interfacial uncompensated spins within the FeMn bottom interfacial monolayers,whereas a relaxation of the pinning strength of the FeMn interfacial spins along the out-of-plane direction occurs at the top interface.XRD analysis indicates the Pt layer upon the FeMn layer forms an fcc(002) texture,implying the magnetic discrepancy between the top and bottom FeMn interfaces has crystalline structural origins. | LIU Yang,FU Yanqiang,JIN Chuan,and FENG Chun Department of Materials Physics and Chemistry,University of Science and Technology Beijing,Beijing 100083,China | 2010 | Rare Metals2010，29，5： | 1 |

| 10 | Human motion prediction using optimized sliding window polynomial fitting and recursive least squares显示文摘Human motion prediction is a critical issue in human-robot collaboration(HRC)tasks.In order to reduce the local error caused by the limitation of the capture range and sampling frequency of the depth sensor,a hybrid human motion prediction algorithm,optimized sliding window polynomial fitting and recursive least squares(OSWPF-RLS)was proposed.The OSWPF-RLS algorithm uses the human body joint data obtained under the HRC task as input,and uses recursive least squares(RLS)to predict the human movement trajectories within the time window.Then,the optimized sliding window polynomial fitting(OSWPF)is used to calculate the multi-step prediction value,and the increment of multi-step prediction value was appropriately constrained.Experimental results show that compared with the existing benchmark algorithms,the OSWPF-RLS algorithm improved the multi-step prediction accuracy of human motion and enhanced the ability to respond to different human movements. | Li Qinghua Zhang Zhao Feng Chao Mu Yaqi You Yue Li Yanqiang | 2021 | The Journal of China Universities of Posts and Telecommunications2021，28，3： | 1 |
| 11 | Optimization of virtual machine placement based on constrained immune memory and immunodominance clone in IaaS cloud mode equipment training显示文摘In infrastructure as a service(IaaS)cloud mode equipment simulated training,to keep the resource utilization ratio in a rational high level,improve the training effect and reduce the system running cost,the problem of training virtual machine(TVM)placement needs to be resolved first.We make analysis to the problem and give the mathematical formulation to the problem.Then,we figure out the principle and target of the TVM placement.Based on above analysis,we propose a constrained immune memory and immunodominance clone(CIMIC)TVM placement optimization algorithm.By reverse optimization of the initial antibody population,the searching range is reduced.The common antibody population and the immunodominance antibody population evolve simultaneously,which realizes the simultaneous progressing of global searching and local searching of solutions.Further,local optimal is avoided by this means.Memory antibody makes ful use of the unfeasible solutions and the diversity of antibody population is maintained.The constraint information of the problem is utilized to improve the optimization effect.Experiment results show that the CIMIC algorithm improves the overall optimization effect of TVM placement,reduces the server number and improves the resource utilization and system stability. | Zhijia Chen Yuanchang Zhu Yanqiang Di Shaochong Feng | 2017 | International Journal of Modeling, Simulation, and Scientific Computing2017，8，1： | 0 |
| 12 | Genomic regions associated with the sex-linked inhibitor of dermal melanin in Silkie chicken显示文摘A unique characteristic of the Silkie chicken is its fibromelanosis phenotype.The dermal layer of its skin,its connective tissue and shank dermis are hyperpigmented.This dermal hyperpigmentation phenotype is controlled by the sex-linked inhibitor of dermal melanin gene(ID)and the dominant fibromelanosis allele.This study attempted to confirm the genomic region associated with ID.By genotyping,ID was found to be closely linked to the region between GGA_rs16127903 and GGA_rs14685542(8406919 bp)on chromosome Z,which contains ten functional genes.The expression of these genes was characterized in the embryo and 4 days after hatching and it was concluded that MTAP,encoding methylthioadenosinephosphorylase,would be the most likely candidate gene.Finally,target DNA capture and sequence analysis was performed,but no specific SNP(s)was found in the targeted region of the Silkie genome.Further work is necessary to identify the causal ID mutation located on chromosome Z. | Ming TIAN Rui HAO Suyun FANG Yanqiang WANG Xiaorong GU Chungang FENG Xiaoxiang HU Ning LI | 2014 | Frontiers of Agricultural Science and Engineering2014，1，3： | 0 |
| 13 | Attention-Based Residual Dense Shrinkage Network for ECG Denoising显示文摘Electrocardiogram(ECG)signal is one of the noninvasive physiological measurement techniques commonly usedin cardiac diagnosis.However,in real scenarios,the ECGsignal is susceptible to various noise erosion,which affectsthe subsequent pathological analysis.Therefore,the effective removal of the noise from ECG signals has becomea top priority in cardiac diagnostic research.Aiming at the problem of incomplete signal shape retention andlow signal-to-noise ratio(SNR)after denoising,a novel ECG denoising network,named attention-based residualdense shrinkage network(ARDSN),is proposed in this paper.Firstly,the shallow ECG characteristics are extractedby a shallow feature extraction network(SFEN).Then,the residual dense shrinkage attention block(RDSAB)isused for adaptive noise suppression.Finally,feature fusion representation(FFR)is performed on the hierarchicalfeatures extracted by a series of RDSABs to reconstruct the de-noised ECG signal.Experiments on the MIT-BIHarrhythmia database and MIT-BIH noise stress test database indicate that the proposed scheme can effectively resistthe interference of different sources of noise on the ECG signal. | Dengyong Zhang Minzhi Yuan Feng Li Lebing Zhang Yanqiang Sun Yiming Ling | 2024 | Computer Modeling in Engineering & Sciences2024，138，3： | 0 |
| 14 | A Bionic Starfish Adsorption Crawling Soft Robot显示文摘A variety of soft wall-climbing robots have been developed that can move in certain patterns.Most of these soft robots can only move on conventional surfaces and lack adaptability to complex surfaces.Improving the adaptability of soft robots on complex surfaces is still a challenging problem.To this end,we study the layered structure of the starfish tube foot and the valve flap structure in the water vascular system,and use an ultrasonic stress detector to study the stiffness distribution of the arm structure.Inspired by the motion of the starfish,we present a bionic soft wall-climbing robot,which is driven by two groups of pneumatic feet and achieves body bending through active adaptation layers.We design the structure of the foot to flex to provide driving force,and there are suction cups at the end of the foot to provide suction.The soft foot has a simple structure design,adapts to a variety of surfaces,and does not damage the surface of the substrate.Variable stiffness layers achieve stiffness changes by the principle of line blocking.The Central Pattern Generator theory is introduced to coordinately control the multiple feet of the robot.After experiments,we verify the adaptability of the soft robot to curved surfaces.The research may provide a reference for the design and development of crawling soft robots on complex surfaces. | Xiangang Huang Chenghao Zhang Wenqi Feng Xiangye Zhang Deyuan Zhang Yanqiang Liu | 2024 | Journal of Bionic Engineering2024，21，1： | 0 |
