| 1 | Genetic basis and breeding application of clonal diversity and dual reproduction modes in polyploid Carassius auratus gibelio显示文摘A unisexual species is generally associated with polyploidy, and reproduced by a unisexual reproduction mode, such as gyno- genesis, hybridogenesis or parthenogenesis. Compared with other unisexual and polyploid species, gibel carp (Carassius au- ratus gibelio) has a higher ploidy level of hexaploid. It has undergone several successive rounds of genome polyploidy, and experienced an additional, more recent genome duplication event. More significantly, the dual reproduction modes, including gynogenesis and sexual reproduction, have been demonstrated to coexist in the polyploid gibel carp. This article reviews the genetic basis concerning polyploidy origin, clonal diversity and dual reproduction modes, and outlines the progress in new va- riety breeding and gene identification involved in the reproduction and early development. The data suggests that gibel carp are under an evolutionary trajectory of diploidization. As a novel evolutionary developmental (Evo-Devo) biology model, this work highlights future perspectives about the functional divergence of duplicated genes and the sexual origin of vertebrate animals. | GUI JianFang* & ZHOU Li State Key Laboratory of Freshwater Ecology and Biotechnology, Institute of Hydrobiology, Chinese Academy of Sciences, Wuhan 430072, China | 2010 | Science China(Life Sciences)2010，53，4： | 62 |

| 3 | Impact of personality and coping mechanisms on health-related quality of life in liver transplantation recipients显示文摘With the great development of liver transplantation in China, long survival and quality of life after liver transplantation have been matters of growing interest. This study was designed to investigate the impact of personality and coping skills on the quality of life after liver transplantation. METHODS:Fifty-five outpatients who had been followed up after liver transplantation at our center were assessed by general quality of life inventory (GQOLI-74 ), a medical coping modes questionnaire (MCMQ), an eysenck personality questionnaire (EPQ), and a general condition questionnaire (GCQ). RESULTS: The score for material well-being was the lowest (63.22±12.67) and for psychological well-being the highest (73.43±12.60) in 4 dimensions of the GQOLI in post transplantation patients. Their main coping method was confrontation (21.40±3.70). The main characteristics of their personality were extraversation (E score 12.96±4.13) and neuroticism (N score 8.20±4.90) . The total score of the GQOLI was positively correlated with confrontation and E score, and it was negatively correlated with acceptance and N score. The physical well-being positively associated with the E score. The psychological well-being was positively correlated with confrontation and L score, and was negatively correlated with acceptance, P and N score. Social well-being was positively correlated with confrontation and E score, and was negatively correlated with acceptance and N score. Material well-being was not correlated with coping methods and personality. CONCLUSION:The quality of life in post liver transplantation patients is associated with their psychological characteristics. | Sai-Jun Zhang, Li-Hua Huang, Yan-Ling Wen, Zhen-Hua Hu, Jing Jin, Li-Hua Shen and Li-Xia Cai Liver Transplantation Center, First Affiliated Hospital, Zhejiang University School of Medicine, Hangzhou 310003, China | 2005 | Hepatobiliary & Pancreatic Diseases International2005，4，3： | 13 |
| 4 | Mechanical properties and failure modes of stratified backfill under triaxial cyclic loading and unloading显示文摘Multiple filling of gobs will lead to a layered structure of the backfill.To explore the influence of layering structure on the mechanical properties and failure modes of backfill,different backfill specimens were prepared with a cement/sand ratio of 1:4,a slurry concentration of 75%,and backfilling times of 1,2,3 and 4,separately.Triaxial cyclic loading and unloading experiments were carried out.The results show that with an increase in backfilling time,the peak strength of backfill decreases as a polynomial function and the peak strain increases as an exponential function.The cyclic load enhances the linear characteristic of backfill deformation.The loading and unloading deformation moduli have a linear negative correlation with the backfilling time.The unloading deformation modulus is always slightly higher than the loading deformation modulus.The failure modes of stratified backfill are mainly characterized by conjugate shear failure at the upper layer and tensile failure across the layer plane,and there is usually no damage in the lower layer away from the loading area. | Wang Jie Song Weidong Cao Shuai Tan Yuye | 2019 | International Journal of Mining Science and Technology2019，29，5： | 11 |
| 5 | Hierarchical ZSM-11 with intergrowth structures:Synthesis,characterization and catalytic properties显示文摘Hierarchical ZSM-11 microspheres with intercrystalline mesoporous properties and rod-like crystals intergrowth morphology have been synthesized using a spot of tetrabutylammonium as a single template.XRD,FTIR,SEM,TEM and N2 adsorption analysis revealed that each individual particle was composed of nanosized rod crystals inserting each other and the intercrystalline voids existing among rods gave a significant mesopore size distribution.Steam treatment result demonstrated the excellent hydrothermal stability of samples.Various crystallization modes including constant temperature crystallization (one-stage crystallization) and two-stage temperature-varying crystallization with different 1st stage durations were investigated.The results suggested that the crystallization modes were mainly responsible for the adjustable particle size and textural properties of samples while the small amount of tetrabutylammonium bromide was mainly used to direct the formation of both ZSM-11 framework and its intergrowth morphology.Furthermore,the performance of optimal ZSM-11 as an active component for the catalytic pyrolysis of heavy oil was also investigated.Compared with the commercial pyrolysis catalyst,the hierarchical ZSM-11 catalyst exhibited a high selectivity to desired products(LPG+gasoline+diesel),as well as a much lower dry gas and coke yield,plus a high selectivity and yield of light olefins(C=3 C=4)and very poor selectivity to benzene.Therefore,fully open micropore-mesopore connectivity would make such hierarchically porous ZSM-11 zeolites very attractive for applications in clean petrochemical catalysis field. | Qingjun Yu Chaoyue Cui Qiang Zhang Jing Chen Yang Li Jinpeng Sun Chunyi Li Qiukai Cui Chaohe Yang Honghong Shan | 2013 | Journal of Energy Chemistry2013，22，5： | 10 |
| 6 | Determinants of prognosis in Talaromyces marneffei infections with respiratory system lesions显示文摘Background: Little study has investigated the differences between Talatomyces marneffei (T. marneffei) respiratory infection and tuberculosis and the prognostic factors of such infection. This study investigated the characteristics and prognostic factors of T. marneffei infections with respiratory lesions and the causes of misdiagnosis. Methods: Clinical characteristics and prognoses of patients with T. marneffei infections with respiratory system lesion were investigated. T. marneffei diagnosis followed isolation from clinical specimens using standard culture, cytology, and histopathology. Survival curves were estimated by using Kaplan-Meier analysis, with log-rank test to compare differences in survival rates between groups. Univariate and multivariate Cox regression analyses were also performed to assess significant differences in clinical characteristics of overall survival. Results: Of 126 patients diagnosed with T. marneffei infections, 63 (50.0%) had T. marneffei respiratory system infections;38.1%(24/63) were misdiagnosed as having tuberculosis. Human immunodeficiency virus (HIV) infection, CD4/CD8 < 0.5, percentage of CD4+ T cells <42.8%, and length of time from onset to confirmation of diagnosis >105 days were potential risk factors for poor prognoses. Length of time from onset to confirmation of diagnosis persisted as an independent predictor of all-cause mortality in multivariate analysis (odds ratio: 0.083, 95.0% confidence interval: 0.021–0.326, P < 0.001). However, the size of the lung lesions, dyspnea, thoracalgia, mediastinal lymphadenopathy, and pleural effusion did not significantly predict overall survival. There was no significant difference in prognosis according to the type of treatment. Conclusions: T. marneffei infections involving the respiratory system are common. The critical determinants of prognosis are HIV infection, CD4/CD8, percentage of CD4+ T cells, type of treatment, and the time range from onset to confirmation of diagnosis. Rapid and accurate diagnosis is crucial for improving prognosis. | Jian-Quan Zhang Mian-Luan Pan Wen Zeng Shu-Dan Tang Cai-Mei Tan | 2019 | Chinese Medical Journal2019，，16： | 10 |
| 7 | Preliminary study on the mode of occurrence of arsenic in high arsenic coals from southwest Guizhou Province显示文摘Coal samples from high arsenic coal areas have been analyzed by electron microprobe analyzer ( EMPA) , scanning electron microscopy with an energy dispersive X-ray analyzer (SEM-EDX) , X-ray diffraction analysis (XRD) , low temperature ashing (LTA) , transmission electron microscopy (TEM) , X-ray absorption fine structure (XAFS) , instrument neutron activation analysis (INAA) and wet chemical analysis. Although some As-bearing minerals such as pyrite, arsenopyrite, realgar (?), As-bearing sulfate, and As-bearing clays are found in the high arsenic coals, their contents do not account for the abundance of arsenic in the some coals. Analysis of the coal indicates that arsenic exists mainly in the form of As5+ and As3+ , combined with compounds in the organic matrix. The occurrence of such exceptionally high arsenic contents in coal and the fact that the arsenic is dominantly organically associated are unique observations. The modes of occurrence of arsenic in high As-coals are discussed. | 丁振华 郑宝山 张杰 H. E. Belkin R. B. Finkelman 赵峰华 周代兴 周运书 陈朝刚 | 1999 | Science China Earth Sciences1999，42，6： | 8 |
| 8 | Energy dependence on modes of electric activities of neuron driven by different external mixed signals under electromagnetic induction显示文摘Energy supply and release play an important role in individual neuron and neural network. In this paper, the electrical activities and Hamilton energy of neuron are investigated when external mixed signals(i.e., the periodic stimulus current and the periodic electromagnetic field) are imposed on the neuron under the electromagnetic induction. As a result, the Hamilton energy is much dependent on the mode transition, the multiple electric activity modes and the numerical analysis of Hamilton energy are more complicated under various parameters. When the periodic high-low frequency electromagnetic radiation is imposed in neuron, it is found that the electrical activities are more complex, and the changing of energy is obvious. In addition, the response of electrical activity and Hamilton energy is much dependent on the changing of amplitude A, B when the external high-low frequency signal is imposed on the neuron, meanwhile, the energy of bursting state is lower than the one of spiking state. It can be used for investigation about the energy coding in the neuron even the neuron networks. | LU LuLu JIA Ya XU Ying GE MengYan YANG LiJian ZHAN Xuan | 2019 | Science China(Technological Sciences)2019，62，3： | 8 |
| 9 | Investigation on nonlinear lateral-torsional coupled vibration of a rotor system with substantial unbalance显示文摘Substantial unbalance may be caused by fan blade off during the operation period of gas turbine engines,and related dynamic problems are very critical to the safety design of rotor system in aero-engine.This article aims to understand lateral-torsional coupled vibration of the rotor system with substantial unbalance.The governing equation of a modified unbalanced rotor system is established based on Lagrangian approach.Then,a mathematical analytical method is proposed in which a linear approximation is derived and the Floquet theory and Hill’s method are incorporated,from which the modal characteristics of the unbalanced rotor are obtained.The modal characteristics of the unbalanced rotor system are revealed comprehensively for the first time.Furthermore,the relation between the modes and responses of the unbalanced rotor is discussed in detail.The results show that the lateral vibration and torsional vibration of the unbalanced rotor are coupled through the inertial terms in the governing equations.Due to the coupling,veering and lock-in phenomena occur between the frequencies of the forward whirl mode and the torsional mode.Furthermore,lock-in can lead to a kind of principal instability.With regard to the response of the unbalanced rotor,both natural vibration components and enforced vibration components appear in the lateral response,while only natural vibration components appear during torsional vibration.Moreover,natural vibration components play a crucial role in the response within the principal instability region and cause divergence of the vibration amplitudes in the lateral and torsional directions. | Jie HONG Pingchao YU Yanhong MA Dayi ZHANG | 2020 | Chinese Journal of Aeronautics2020，33，6： | 8 |
| 10 | Reconfigurable directional coupler in lithium niobate crystal fabricated by three-dimensional femtosecond laser focal field engineering显示文摘For crystals, depressed cladding waveguides have advantages such as preservation of the spectroscopic as well as non-linear properties and the capability to guide both horizontal and vertical polarization modes, but fabrication is always quite time consuming. In addition, it is usually difficult to couple modes propagating in different depressed cladding waveguides through evanescent field overlap, so it is often required to dynamically reconfigure photonic waveguide devices using external fields for classical or quantum applications. Here, we experimentally demonstrate the single-scan femtosecond laser transverse writing of depressed cladding waveguides to form a 2 × 2 directional coupler inside lithium niobate crystal, which is integrated with two deeply embedded microelectrodes on both sides of the interaction region to reconfigure the coupling. By focal field engineering of the femtosecond laser, we specially generate a three-dimensional longitudinally oriented ring-shaped focal intensity profile composed of 16 discrete spots to simultaneously write the entire cladding region. The fabricated waveguides exhibit good single guided modes in two orthogonal polarizations at 1550 nm. By applying voltage to the deeply embedded microelectrodes fabricated with the femtosecond laser ablation followed by selective electroless plating, we successfully facilitate the light coupling from the input arm to the cross arm and thus actively tune the splitting ratio. These results open new important perspectives in the efficient fabrication of reconfigurable complex three-dimensional devices in crystals based on depressed cladding waveguides. | Qian Zhang Meng Li Jian Xu Zijie Lin Haofeng Yu Min Wang Zhiwei Fang Ya Cheng Qihuang Gong Yan Li | 2019 | Photonics Research2019，7，5： | 7 |
| 11 | Modes of occurrence of arsenic in high-arsenic coal by extended X-ray absorption fine structure spectroscopy显示文摘The concentration ranges of As and Sb in six Late Permian high-arsenic coals collected from Xingren and Xingyi, Guizhou Province are 94.1 μg·g -1-3 2 and 8 1 μg·g -1-120 μg·g -1, respectively. Based on the mineralogical analysis, no arsenic and arsenic-bearing minerals are detected in these samples and arsenic occurs in coal macerals. By extended X-ray absorption fine structure(EXAFS) spectroscopy, we have found that arsenic in these high-arsenic coal samples coordinates with oxygen; the coordination number of As with oxygen for these samples is 4 except one sample(H-9) for which the coordination number of As is 3. Therefore, arsenic in these high-arsenic coals does not occur in sulfide minerals, but occurs in arsenate or arsenite phase, and the preponderance of As is in arsenate of As 5+. | Fenghua Zhao Deyi Ren Baoshan Zheng Tiandou Hu Tao Liu | 1998 | Chinese Science Bulletin1998，43，19： | 7 |
| 12 | On the placement of actuators and sensors for flexible structures with closely spaced modes显示文摘This paper analyzed the fundamental limitations of previous work and developed a new method to optimally locate actuators and sensors for structures with close modes. Optimization criteria were defined based on the distinguishing modal controllability and observability measures of close modes. An appropriate genetic algorism was adopted as the optimization algorism. Solving the high order Lyapunov functions was avoided by means of the closed-form expressions for controllability and observability Grammians. Since structure with widely separated natural frequencies is approximately balanced, computational efficiency was improved by grouping close modes together and dealing with the resulting subsystems independently. Finally, the effectiveness and optimality of the novel placement scheme were verified on a model structure with close modes. | LIU XiaoXiang1,2 & HU Jun1,2 1 Beijing Institute of Control Engineering, Beijing 100190, China 2 State Key Laboratory of Science and Technology on Space Intelligent Control, Beijing 100190, China | 2010 | Science China(Technological Sciences)2010，53，7： | 7 |

| 14 | Preliminary survivability analysis of manned spacecraft following orbital debris penetration显示文摘Meteoroid and orbital debris(M/OD) may cause severe damages or even catastrophic failures for long-term manned spacecrafts in orbit due to the hypervelocity impact(HVI) destruction.It is essential to quantitatively assess the M/OD risk of manned spacecraft.In this paper,the catastrophic failure as-sessment function is successfully integrated into the Meteoroid & Orbital Debris Assessment and Op-timization System Tools(MODAOST),which is the M/OD risk assessment system developed by China Academy of Space Technology.The survivability assessment for the US Lab by MODAOST was con-sistent with that of the Manned Spacecraft Crew Survivability computer code(MSCSurv).Meanwhile,the simulation process showed that this function was more effective than MSCSurv for the application of the standard methodology of M/OD risk assessment instead of the Monte Carlo model.This function expands the ability of MODAOST in predicting the survivability of the typical catastrophic failure modes such as crew hypoxia and the critical cracking. | ZHANG Yong HAN ZengYao LI Ming ZHENG ShiGui | 2009 | Science China(Technological Sciences)2009，52，5： | 6 |
| 15 | Study on integrated development and hybrid operation mode of nuclear power plant and pumped-storage power station显示文摘The nuclear power plant is suitable for base-load operation, while the pumped-storage unit mainly gives play to capacity benefit in the electric power system;hence, the integrated development and hybrid operation mode of the two can better meet the needs of the electric power system.

| 18 | Employing incomplete complex modes for model updating and damage detection of damped structures显示文摘In the study of finite element model updating or damage detection,most papers are devoted to undamped systems.Thus,their objective has been exclusively restricted to the correction of the mass and stiffness matrices.In contrast,this paper performs the model updating and damage detection for damped structures.A theoretical contribution of this paper is to extend the cross-model cross-mode(CMCM) method to simultaneously update the mass,damping and stiffness matrices of a finite element model when only few spatially incomplete,complex-valued modes are available.Numerical studies are conducted for a 30-DOF(degree-of-freedom) cantilever beam with multiple damaged elements,as the measured modes are synthesized from finite element models.The numerical results reveal that applying the CMCM method,together with an iterative Guyan reduction scheme,can yield good damage detection in general.When the measured modes utilized in the CMCM method are corrupted with irregular errors,assessing damage at the location that possesses larger modal strain energy is less sensitive to the corrupted modes. | HU Sau-Lon James | 2008 | Science China(Technological Sciences)2008，51，12： | 4 |
| 19 | Influences of personality characteristics and coping modes on anxiety in primary glaucoma patients显示文摘AIM: To examine the influences of personality characteristics and coping modes on the anxiety of primary glaucoma patients.METHODS: A total of 200 individuals, including 50 with primary angle-closure glaucoma, 60 with primary open angle glaucoma and 90 control participants, filled out the State-Trait Anxiety Inventory, NEO Five-Factor Inventory, and Medical Coping Modes Questionnaire. Sociodemographic information was also collected. Data were analyzed via the Spearman rank correlation test and stepwise regression.RESULTS: The personality and coping variables are predictive and jointly account for a significant amount (45.3%-54.2%) of variance across the two subscales of anxiety measures. Notably, neuroticism seems to be most closely related to anxiety disturbances in glaucoma patients. The level of resignation is positively linked to anxiety scores.CONCLUSION: Some personality factors and coping modes help to predict the process of anxiety disorders in primary glaucoma patients. Recognizing the predictive role of these variables in the patients may further enrich clinical research in glaucoma and help to design more effective interventions involving both ophthalmology and psychiatry. | Jie Chen Ze-Nan Lin Yan-Ting Tao Qing-Ning Zhao Qian Li Hai Yang Ping Xu Jian-Mei Chen Xi-Quan Ma Hong-Ping Cui | 2019 | International Journal of Ophthalmology(English edition)2019，12，7： | 4 |
| 20 | Improved method for zero-energy mode suppression in peridynamic correspondence model显示文摘The peridynamic correspondence model provides a general formulation to incorporate the classical local model and,therefore,helps to solve mechanical problems with discontinuities easily.But it suffers from zero-energy mode instability in numerical implementation due to the approximation of deformation gradient tensor.To suppress zero-energy modes,previous stabilized methods were generally more based on adding a supplemental force state derived from bond-based peridynamic theory,which requires a bond-based peridynamic micro-modulus.In this work,we present an improved stabilized method where the stabilization force state is derived directly from the peridynamic correspondence model.Hence,the bond-based peridynamic micro-modulus is abandoned.This improved method needs no extra constant to control the magnitude of stabilization force state and it is suitable for either isotropic or anisotropic materials.Several examples are presented to demonstrate its performance in simulating crack propagation,and numerical results show its efficiency and effectiveness. | Ji Wan Zhuang Chen Xihua Chu Hui Liu | 2019 | Acta Mechanica Sinica2019，35，5： | 3 |
