1MU-GAN:Facial Attribute Editing Based on Multi-Attention Mechanism显示文摘Facial attribute editing has mainly two objectives:1)translating image from a source domain to a target one,and 2)only changing the facial regions related to a target attribute and preserving the attribute-excluding details.In this work,we propose a multi-attention U-Net-based generative adversarial network(MU-GAN).First,we replace a classic convolutional encoder-decoder with a symmetric U-Net-like structure in a generator,and then apply an additive attention mechanism to build attention-based U-Net connections for adaptively transferring encoder representations to complement a decoder with attribute-excluding detail and enhance attribute editing ability.Second,a self-attention(SA)mechanism is incorporated into convolutional layers for modeling long-range and multi-level dependencies across image regions.Experimental results indicate that our method is capable of balancing attribute editing ability and details preservation ability,and can decouple the correlation among attributes.It outperforms the state-of-the-art methods in terms of attribute manipulation accuracy and image quality.Our code is available at http://gffzz188fe103f8f1460ascnqp6xbuub9v69qw.ffgz.tsg.suse.edu.cn/SuSir1996/MU-GAN.Ke Zhang Yukun Su Xiwang Guo Liang Qi Zhenbing Zhao 2021IEEE/CAA Journal of Automatica Sinica2021,8,9:4
2Progress in octahedral spherical hohlraum study显示文摘In this paper,we give a review of our theoretical and experimental progress in octahedral spherical hohlraum study.From our theoretical study,the octahedral spherical hohlraums with 6 Laser Entrance Holes(LEHs)of octahedral symmetry have robust high symmetry during the capsule implosion at hohlraum-to-capsule radius ratio larger than 3.7.In addition,the octahedral spherical hohlraums also have potential superiority on low backscattering without supplementary technology.We studied the laser arrangement and constraints of the octahedral spherical hohlraums,and gave a design on the laser arrangement for ignition octahedral hohlraums.As a result,the injection angle of laser beams of 50°-60°was proposed as the optimum candidate range for the octahedral spherical hohlraums.We proposed a novel octahedral spherical hohlraum with cylindrical LEHs and LEH shields,in order to increase the laser coupling efficiency and improve the capsule symmetry and to mitigate the influence of the wall blowoff on laser transport.We studied on the sensitivity of the octahedral spherical hohlraums to random errors and compared the sensitivity among the octahedral spherical hohlraums,the rugby hohlraums and the cylindrical hohlraums,and the results show that the octahedral spherical hohlraums are robust to these random errors while the cylindrical hohlraums are the most sensitive.Up till to now,we have carried out three experiments on the spherical hohlraum with 2 LEHs on Shenguang(SG)laser facilities,including demonstration of improving laser transport by using the cylindrical LEHs in the spherical hohlraums,spherical hohlraum energetics on the SGIII prototype laser facility,and comparisons of laser plasma instabilities between the spherical hohlraums and the cylindrical hohlraums on the SGIII laser facility.Ke Lan Jie Liu Zhichao Li Xufei Xie Wenyi Huo Yaohua Chen Guoli Ren Chunyang Zheng Dong Yang Sanwei Li Zhiwen Yang Liang Guo Shu Li Mingyu Zhang Xiaoying Han Chuanlei Zhai Lifei Hou Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Feng Wang Guanghui Yuan Haijun Zhang Bobin Jiang Lizhen Huang Wei Zhang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Xuewei Deng Dongxia Hu Wei Zhou Huaiting Jia Yongkun Ding Wanguo Zheng Xiantu He 2016Matter and Radiation at Extremes2016,1,1:2
3Solution processed low power organic field-effect transistor bio-chemical sensor of high transconductance efficiency显示文摘Developing organic field-effect transistor(OFET)biosensors for customizable detection of biomarkers for many diseases would provide a low-cost and convenient tool for both biological studies and clinical diagnosis.In this work,design principles of the OFET transducer for biosensors were derived to relate the signal-to-noise ratio(SNR)to the device-performance parameters.Steep subthreshold swing(SS),proper threshold voltage(Vth),good-enough bias-stress stability,and mechanical durability are shown to be the key prerequisites for realizing OFET bio-sensors of high transconductance efficiency(gm/ID)for large SNR.Combining a low trap-density channel and a high-k/low-k gate dielectric layer,low-temperature(<100℃)solution-processed flexible OFETs can meet the performance requirements to maximize the gm/ID.An extended gate-structure OFET biosensor was further implemented for label-free detection of miR-21,achieving a detection limit below 10 pM with high selectivity at a low operation voltage(<1 V).Wei Tang Ying Fu Yukun Huang Yuanzhe Li Yawen Song Xin Xi Yude Yu Yuezeng Su Feng Yan Xiaojun Guo 2022npj Flexible Electronics2022,6,1:1
4Corrigendum to“First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole”[Matter Radiation Extremes 1(1)(2016)2-7]显示文摘Corrigendum Text:On page 2 of this letter,there is a misprint in the unit.The unit of the geometrical dimension of the spherical hohlraums on this page should always be“mm”rather than“mm”,i.e.in the second paragraph,“…with 800 J per beam at 0.35 mm…”should be“…with 800 J per beam at 0.35 mm…”,“The slit of 400 mm width is parallel…”should be“The slit of 400 mm width is parallel…”,“The laser focal diameter is about 500 mm…”should be“The laser focal diameter is about 500 mm…”;in the third paragraph,“…we take 850 mm as the radius…”should be“…we take 850 mm as the radius…”,“The LEH radius R_(L) is 400 mm…”should be“The LEH radius R_(L) is 400 mm…”,“…the radius of the cylindrical LEH outer ring is taken as 1.5 R_(L)=600 mm”should be“…the radius of the cylindrical LEH outer ring is taken as 1.5 R_(L)=600 mm”.This mistake does not affect any of the main results of the original letter.Wenyi Huo Zhichao Li Dong Yang Ke Lan Jie Liu Guoli Ren Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Xuefei Xie Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Guanghui Yuan Haijun Zhang Baibin Jiang Lizhen Huang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Yongkun Ding Xiantu He Weiyan Zhang 2016Matter and Radiation at Extremes2016,1,2:1
5Void fraction for random loose packing of the cylindrical particles considering filling rate,material and shape显示文摘Particle packing is widely applied in organic pollutant adsorption,catalytic reaction.biomass combustion,nuclear cooling,and other scenarios.Due to the complexity of the shape,the studies on the void fraction of the cylindrical particles are not as thorough as the spherical particles.This study investigated the influence of the flling rate,material properties and sphericity on the void fraction of cylinders through experiments and simulation.DEM(discrete element method)was validated by the internal structures of the packing obtained by CT(computed tomography).Based on the logarithmic correlation between the void fraction and flling rate,an ingenious framework for predicting the void fraction of cylindrical particles was presented with two intermediate coefficients.By correlating the coefficients with the material property and sphericity,a novel void-fraction prediction model was established with R-squared of 0.996.The mechanism of void fraction under random loose packing for cylinders was eventually found in this study.Chengquan Zhang Jun Gao Yukun Xu Yunfei Xia Xiaobin Wei Xing Su Lingjie Zeng 2022Particuology2022,20,4:1
6Mixed L_1/H-infinity control for uncertain linear singular systems显示文摘The mixed L1/H-infinity control problem for a class of uncertain linear singular systems is considered using a matrix inequality approach.The purpose is to design a state feedback control law such that the resultant closed-loop system is regular,impulse-free,stable and satisfies some given mixed L1/H-infinity performance.A sufficient condition for the existence of such control law is given in terms of a set of matrix inequalities by the introduction of inescapable set and *-norm.When these matrix inequalities are feasible,an explicit expression of the desired state feedback control law is given.A numerical example is used to demonstrate the applicability of the proposed approach.Xiaofu JI Yukun SUN Yonghong HUANG Hongye SU 2009控制理论与应用(英文版)2009,7,2:0
7Antifertility effects of levonorgestrel,quinestrol,and their mixture(EP-1)on plateau zokor in the Qinghai–Tibetan Plateau显示文摘The plateau zokor(Eospalax baileyi)is a key species in the Qinghai-Tibetan Plateau ecosystem,and fertility control could be an ideal approach to manage populations of this subterranean species.In this laboratory study,we explored the effects of the mixture of levonorgestrel and quinestrol(EP-1,1:2),quinestrol(E),and levonorgestrel(P)on the reproductive status of plateau zokors.Groups of 5 animals of each sex were treated with different concentrations of EP-1(1,5,and 10 mg/kg),E(0.33,3.3,and 6.6 mg/kg),and P(0.67,3.35,and 6.7 mg/kg)by oral gavage over 7 successive days and killed on day 15.Body mass reduction was observed in the EP-1 and E groups.EP-1 and E significantly reduced the weight of testis and epididymis at 10 and 3.3 mg/kg,respectively.Sperm count and motility were significantly reduced by 5 mg/kg EP-1 and 0.33 mg/kg E.The levels of serum testosterone,estradiol,luteinizing hormone,and follicle stimulating hormone were significantly reduced by 5 mg/kg EP-1 and 3.3 mg/kg E.EP-1 and E significantly increased the uterine and ovarian weights at 10 and 3.3 mg/kg,respectively.In the plateau zokors,treatment with P had no influence on the reproductive status.These data demonstrate that EP-1 and E have an inhibitory effect on a range of reproductive parameters in the plateau zokors.Further assessment is required to determine the effects on breeding and recruitment in enclosure orfield experiments.Yukun KANG Yuchen TAN Chan WANG Baohui YAO Kang AN Ming LIU Junhu SU 2022Integrative Zoology2022,17,6:0
8A comprehensive construction of the domain ontology for stratigraphy显示文摘Stratigraphic knowledge,the cornerstone of geoscience,needs to be represented by the Knowledge Graph based upon ontology,in order to apply the state-of-the-art big-data techniques.This study aims to comprehensively construct the ontologies for the stratigraphic domain.This has been achieved by a federated,crowd intelligence-based collaboration among domain experts of major stratigraphic subdisciplines.The initial step is to enumerate key terms from authoritative references and incorporate them into the Geoscience Professional Knowledge Graphs(GPKGs)of Deep-time Digital Earth Project.During this process,semantic heterogeneities were meticulously addressed by professional judgement aided by an automatic detection of Homonyms at the GPKGs platform.Afterwards,these terms were further differentiated as either classes or properties and arranged in a hierarchical framework in a top-down process.Consequently,seven ontologies are constructed for major stratigraphic branches,i.e.,Lithostratigraphy,Biostratigraphy,Chronostratigraphy,Chemostratigraphy,Magnetostratigraphy,Cyclostratigraphy and Sequence Stratigraphy.The ontology of Biostratigraphy,among them,is elaborated here,as no biostratigraphic ontology has been attempted before to our knowledge.The constructed biostratigraphic ontology comprises following major root classes:Fossil,Biostratigraphic unit,Biostratigraphic horizon.Altogether,they contribute to the eventual dating and correlating of strata in another root class:Biostratigraphic correlation.In summary,the achievements of this study are probably heretofore the most comprehensive ontologies for the stratigraphic domain.Moreover,a proto model of semantic search engine was conceived to discuss potential application of our work for better querying stratigraphic references,utilizing the semantic liaison of the classes in the constructed ontologies.Huiqing Xu Yingying Zhao Hao Huang Shaochun Dong Yukun Shi Chunju Huang Huaichun Wu Zhiqi Qian Qiang Fang Huaguo Wen Zhongtang Su Shuang Dai Ronghua Wang Chao Li Chao Sun Junxuan Fan 2023Geoscience Frontiers2023,14,5:0
9First demonstration of improving laser propagation inside the spherical hohlraums by using the cylindrical laser entrance hole显示文摘The octahedral spherical hohlraums have natural superiority in maintaining high radiation symmetry during the entire capsule implosion process in indirect drive inertial confinement fusion.While,in contrast to the cylindrical hohlraums,the narrow space between the laser beams and the spherical hohlraum wall is usually commented.In this Letter,we address this crucial issue and report our experimental work conducted on the SGIII-prototype laser facility which unambiguously demonstrates that a simple design of cylindrical laser entrance hole(LEH)can dramatically improve the laser propagation inside the spherical hohlraums.In addition,the laser beam deflection in the hohlraum is observed for the first time in the experiments.Our 2-dimensional simulation results also verify qualitatively the advantages of the spherical hohlraums with cylindrical LEHs.Our results imply the prospect of adopting the cylindrical LEHs in future spherical ignition hohlraum design.Wenyi Huo Zhichao Li Dong Yang Ke Lan Jie Liu Guoli Ren Sanwei Li Zhiwen Yang Liang Guo Lifei Hou Xuefei Xie Yukun Li Keli Deng Zheng Yuan Xiayu Zhan Guanghui Yuan Haijun Zhang Baibin Jiang Lizhen Huang Kai Du Runchang Zhao Ping Li Wei Wang Jingqin Su Yongkun Ding Xiantu He Weiyan Zhang 2016Matter and Radiation at Extremes2016,1,1:0
10Transcriptomic and machine learning analyses identify hub genes of metabolism and host immune response that are associated with the progression of breast capsular contracture显示文摘Capsular contracture is a prevalent and severe complication that affects the post-operative outcomes of patients who receive silicone breast implants.At present,prosthesis replacement is the major treatment for capsular contracture after both breast augmentation procedures and breast reconstruction following breast cancer surgery.However,the mecha-nism(s)underlying breast capsular contracture remains unclear.This study aimed to identify the biological features of breast capsular contracture and reveal the potential underlying mechanism using RNA sequencing.Sample tissues from 12 female patients(15 breast capsules)were divided into low capsular contracture(LCC)and high capsular contracture(HCC)groups based on the Baker grades.Subsequently,41 lipid metabolism-related genes were identified through enrichment analysis,and three of these genes were identified as candidate genes by SVM-RFE and LASSO algorithms.We then compared the proportions of the 22 types of im-mune cells between the LCC and HCC groups using a CIBERSORT analysis and explored the Cor-relation between the candidate hub features and immune cells.Notably,PRKAR2B was positively correlated with the differentially clustered immune cells,which were M1 macro-phages and follicular helper T cells(area under the ROC=0.786).In addition,the expression of PRKAR2B at the mRNA or protein level was lower in the HCC group than in the LCC group.Potential molecular mechanisms were identified based on the expression levels in the high and low PRKAR2B groups.Our findings indicate that PRKAR2B is a novel diagnostic biomarker for breast capsular contracture and might also influence the grade and progression of capsularcontracture.Yukun Mao Xueying Hou Su Fu Jie Luan 2024Genes & Diseases2024,11,3:0
