| 1 | Towards reliable Arctic sea ice prediction using multivariate data assimilation显示文摘Rapid declines in Arctic sea ice have captured attention and pose significant challenges to a variety of stakeholders. There is a rising demand for Arctic sea ice prediction at daily to seasonal time scales, which is partly a sea ice initial condition problem. Thus, a multivariate data assimilation that integrates sea ice observations to generate realistic and skillful model initialization is needed to improve predictive skill of Arctic sea ice. Sea ice data assimilation is a relatively new research area. In this review paper, we focus on two challenges for implementing multivariate data assimilation systems for sea ice forecast. First, to address the challenge of limited spatiotemporal coverage and large uncertainties of observations, we discuss sea ice parameters derived from satellite remote sensing that(1) have been utilized for improved model initialization, including concentration, thickness and drift, and(2) are currently under development with the potential for enhancing the predictability of Arctic sea ice, including melt ponds and sea ice leads. Second, to strive to generate the ‘‘best' estimate of sea ice initial conditions by combining model simulations/forecasts and observations, we review capabilities and limitations of different data assimilation techniques that have been developed and used to assimilate observed sea ice parameters in dynamical models. | Jiping Liu Zhiqiang Chen Yongyun Hu Yuanyuan Zhang Yifan Ding Xiao Cheng Qinghua Yang Lars Nerger Gunnar Spreen Radley Horton Jun Inoue Chaoyuan Yang Ming Li Mirong Song | 2019 | Science Bulletin2019,64,1: | 10 |
| 2 | A study on in vitro and in vivo bioactivity of nano hydroxyapatite/polymer biocomposite显示文摘When bioactive materials are implanted in vivo, a bone-like apatite layer can be found on their surfaces, which is critical to the establishment of bone-bonding between materials and living tissues. In this study, bone-like apatite formation in vitro and in vivo on surface of nano apatite/polyamide (n-HA/PA66) composite was investigated, and the interface between the implanted composite and surrounding bone tissue of rabbit were also examined. The results revealed that in both simulated body fluids (SBF) and dorsal muscles of rabbit, bone-like apatite could form on the biocomposite surface. When the samples were implanted in cortical bone, they combined directly with the natural bone without fibrous tissue in-between. The results showed that the n-HA/PA66 biocomposite had excellent bioactivity, which might be a good candidate for bone defect replacement. | YANG Kong WEI Jie WANG ChaoYuan LI YuBao | 2007 | Chinese Science Bulletin2007,52,2: | 8 |
| 3 | Approach to stochastic multi-attribute decision problems using rough sets theory显示文摘Multi-attribute decision problems where the performances of the alternatives are random variables are considered. The suggested approach grades the probabilities of preference of one alternative over another with respect to the same attribute. Based on the graded probabilistic dominance relation, the pairwise comparison information table is defined. The global preferences of the decision maker can be seen as a rough binary relation. The present paper proposes to approximate this preference relation by means of the graded probabilistic dominance relation with respect to the subsets of attributes. At last, the method is illustrated by an example. | Yao Shengbao Yue Chaoyuan | 2006 | Journal of Systems Engineering and Electronics2006,17,1: | 8 |
| 4 | DMP1 prevents osteocyte alterations,FGF23 elevation and left ventricular hypertrophy in mice with chronic kidney disease显示文摘During chronic kidney disease (CKD),alterations in bone and mineral metabolism include increased production of the hormone fibroblast growth factor 23 (FGF23) that may contribute to cardiovascular mortality.The osteocyte protein dentin matrix protein 1 (DMP1) reduces FGF23 and enhances bone mineralization,but its effects in CKD are unknown.We tested the hypothesis that DMP1 supplementation in CKD would improve bone health,prevent FGF23 elevations and minimize consequent adverse cardiovascular outcomes.We investigated DMP1 regulation and effects in wild-type (WT) mice and the Col4a3^-/- mouse model of CKD.Col4a3^-/- mice demonstrated impaired kidney function,reduced bone DMP1 expression,reduced bone mass,altered osteocyte morphology and connectivity,increased osteocyte apoptosis,increased serum FGF23,hyperphosphatemia,left ventricular hypertrophy (LVH),and reduced survival.Genetic or pharmacological supplementation of DMP1 in Col4a3^-/- mice prevented osteocyte apoptosis,preserved osteocyte networks,corrected bone mass,partially lowered FGF23 levels by attenuating NFAT-induced FGF23 transcription,and further increased serum phosphate.Despite impaired kidney function and worsened hyperphosphatemia,DMP1 prevented development of LVH and improved Col4a3^-/- survival.Our data suggest that CKD reduces DMP1 expression,whereas its restoration represents a potential therapeutic approach to lower FGF23 and improve bone and cardiac health in CKD. | Corey Dussold Claire Gerber Samantha White Xueyan Wang Lixin Qi Connor Francis Maralee Capella Guillaume Courbon Jingya Wang Chaoyuan Li Jian Q.

| 5 | Dynamic programming methodology for multi-criteria group decision-making under ordinal preferences显示文摘A method of minimizing rankings inconsistency is proposed for a decision-making problem with rankings of alternatives given by multiple decision makers according to multiple criteria. For each criteria, at first, the total inconsistency between the rankings of all alternatives for the group and the ones for every decision maker is defined after the decision maker weights in respect to the criteria are considered. Similarly, the total inconsistency between their final rankings for the group and the ones under every criteria is determined after the criteria weights are taken into account. Then two nonlinear integer programming models minimizing respectively the two total inconsistencies above are developed and then transformed to two dynamic programming models to obtain separately the rankings of all alternatives for the group with respect to each criteria and their final rankings. A supplier selection case illustrated the proposed method, and some discussions on the results verified its effectiveness. This work develops a new measurement of ordinal preferences’ inconsistency in multi-criteria group decision-making (MCGDM) and extends the cook-seiford social selection function to MCGDM considering weights of criteria and decision makers and can obtain unique ranking result. | Wu Li Guanqi Guo Chaoyuan Yue Yong Zhao | 2010 | Journal of Systems Engineering and Electronics2010,21,6: | 3 |
| 6 | Carbonaceous Nanofibers-titanium Dioxide Nanocomposites: Synthesis and Use as a Platform for Removal of Dye Pollutants显示文摘A mild chemistry route was developed to prepare carbonaceous nanofibers-titanium dioxide(CNF-TiO_2) nanocomposites for removal of dye pollutants. In the process of the template-directed hydrothermal carbonization(HTC), ultrathin Te nanowires were adopted as templates and glucose as the carbon source, and TiO_2 was decorated on CNF via the hydrolysis of tetrabutyltitanate in the presence of CNF in ethanol. The as-prepared materials were characterized by scanning electron microscopy(SEM), transmission electron microscopy(TEM), energy-dispersive X-ray(EDX) and X-ray diffraction(XRD). SEM and TEM observations displayed that TiO_2 nanoparticles were anchored on the CNF. EDX and XRD data confirmed that the assynthesized samples were CNF-TiO_2, and TiO_2 belonged to anatase titania. Taking advantage of combined benefits of carbonaceous nanofibers and titanium dioxide, these CNF-TiO_2 nanocomposites exhibited higher removal efficiency in a short time and showed good reusability. It was showed that over 97% of Rhodamine B could be removed in 15 min without generating the solid and liquid wastes. The removal efficiency of dyes was still over 80% after reuse in five cycles. All the results demonstrate that the as-prepared CNF-TiO_2 composites are effective materials for fast and effective removal of dye pollutants and thus can provide a new platform for dye decontamination. | 郭洪影 JIANG Shan WANG Chaoyuan LI Shenwan FENG Jianjian 孙红梅 ZHU Hongda GUO Huiling LIU Mingxing SUN Honghao | 2019 | Journal of Wuhan University of Technology(Materials Science)2019,34,2: | 3 |
| 7 | Improving utilization of nests and decreasing mislaid eggs with narrow width of group nests显示文摘Provision of nest boxes is necessary for laying hens,especially in non-cage systems.This study investigated the effects of nest width on nest utilization and mislaid eggs.Hy-Line Browns hens were transferred from conventional cages to perchery pens at 12 weeks of age.Two experiments were conducted to mutually verify the hypothesis that narrowing group nests would improve nest utilization and reduce mislaid eggs.In experiment 1,group nests of 150 cm wide in two pens were partitioned at intervals of 50 cm and 37 cm,respectively.In experiment 2,partition panels were removed after acclimation.The number of mislaid eggs and nest eggs in each pre-set section were compared.Results indicated that narrowing group nests had positive effects on improving usage uniformity and efficiency of group nests.Nest eggs were more evenly distributed on the egg belt in both narrowed group nests,which was indicated by the significant decrease of variance among different sections(p<0.001).The proportion of mislaid eggs decreased by 3.5%in 37 cm treatment(p<0.05)and 4.7% in 50 cm treatment(p<0.001),respectively.As expected,reuse of the 150 cm group nests after removal of partition panels lowered the usage uniformity of group nests.A growth of three percentage points was found for the proportion of mislaid eggs after removing the partition panels in 50 cm treatment.The present results indicated that it is the width of the nest box that works for a better use of group nests.In conclusion,adding partition panels at intervals of 50 cm and 37 cm in group nests both are effective on nest usage and decreasing the occurrence of mislaid eggs. | Hongya Zheng Baoming Li Gang Chen Chaoyuan Wang | 2018 | International Journal of Agricultural and Biological Engineering2018,11,1: | 2 |

| 11 | A Knowledge Base System for Operation Optimization: Design and Implementation Practice for the Polyethylene Process显示文摘Setting up a knowledge base is a helpful way to optimize the operation of the polyethylene process by improving the performance and the ef ciency of reuse of information and knowledge two critical ele- ments in polyethylene smart manufacturing. In this paper, we propose an overall structure for a knowl- edge base based on practical customer demand and the mechanism of the polyethylene process. First, an ontology of the polyethylene process constructed using the seven-step method is introduced as a carrier for knowledge representation and sharing. Next, a prediction method is presented for the molecular weight distribution (MWD) based on a back propagation (BP) neural network model, by analyzing the relationships between the operating conditions and the parameters of the MWD. Based on this network, a differential evolution algorithm is introduced to optimize the operating conditions by tuning the MWD. Finally, utilizing a MySQL database and the Java programming language, a knowledge base system for the operation optimization of the polyethylene process based on a browser/server framework is realized. | Weimin Zhong Chaoyuan Li Xin Peng Feng Wan Xufeng An Zhou Tian | 2019 | Engineering2019,5,6: | 1 |
