| 1 | Emergency material scheduling optimization model and algorithms:A review显示文摘In the emergency management of disruptions,efficient emergency material scheduling(EMS) is a key factor to save people’s lives and reduce loss.Based on the literature of EMS and related areas in recent years,the research was summarized from two aspects of EMS optimization model and algorithms.It is concluded that the EMS optimization models mainly aim at the shortest time,shortest distance,minimum cost,maximum satisfaction and fairness,etc.The constraints usually include the quantity of supply depots,relief supply and vehicles,the types of commodities,the road network conditions,the budgets and the demand forecast of emergency materials.Multi-objective model is more complex and it usually considers more than one objective.To find the optimized solution,the multiobjective model with complex constraints needs more efficient algorithms.The existing algorithms,including mathematic algorithm and heuristic algorithm,have been categorized.For NP-hard(non-deterministic polynomial hard) problems,heuristic algorithms should be designed,which mainly include genetic algorithm(GA),ant colony optimization(ACO),particle swarm optimization(PSO),etc.Based on the characteristics of the optimization model and various algorithms,appropriate algorithm or tools should be chosen and designed to obtain the optimized solution of EMS model.Finally,the development trends of EMS optimization model and algorithm in the future are proposed. | Hui Hu Jing He Xiongfei He Wanli Yang Jing Nie Bin Ran | 2019 | Journal of Traffic and Transportation Engineering(English Edition)2019，6，5： | 11 |
| 2 | Carbon and oxygen isotopes analyses for the Sinian carbonates in the Helan Mountain, North China显示文摘We conducted detailed studies of the Sinian carbonates from the Helan Mountain,Ningxia by both field investigation and laboratory analyses of carbon and oxygen isotopes.The carbon isotopic compositions of the Sinian Zhengmuguan Formation shows variations with regularity in the five studied sections,theδ13C values all gradually decrease from bottom to top,with a total range from 4.51‰to 0.11‰,and the biggest negative excursion reaches up to 6.88‰.In addition,abundant macro-body fossils were also found from the Tuerkeng Formation in this study,similar to those found from the Dengying Formation in the South China Block.This observation firmly constrained the age for the Zhengmuguan and Tuerkeng formations to the Sinian period.Here we interpreted that the Zhengmuguan Formation formed during a glacial period when the extremely cold climate substantially decreased the amount of burial of organic matter in the ocean and thus led to the general negativeδ13C excursion.The increasingδ13C values in the Tuerkeng Formation dolomites imply the ending of the glacial period in the Zhengmuguan epoch,biological recovery and increase of organic matter burial in the ocean occurred during this period.Comparing our obtained carbon and oxygen isotopes of the Zhengmuguan and Tuerkeng formations with those of coeval carbonate successions from other places all over the world,the Zhengmuguang-aged glacial deposits might be deposited after the Gaskiers glaciation.This study provides important information for paleo-ocean,paleogeographic and biological evolution in the North China Block during the Ediacaran period and adds new carbon and oxygen isotopes data for the global Sinian carbon-oxygen isotopes dataset. | YANG Jie ZENG ZuoXun CAI XiongFei LI ZhiYong LI TianBin MENG Fang HE WenJian | 2013 | Chinese Science Bulletin2013，58，32： | 8 |
| 3 | Laminar Distribution of Neurochemically-Identified Interneurons and Cellular Co-expression of Molecular Markers in Epileptic Human Cortex显示文摘Inhibitory GABAergic interneurons are fundamental elements of cortical circuits and play critical roles in shaping network activity. Dysfunction of interneurons can lead to various brain disorders, including epilepsy,schizophrenia, and anxiety. Based on the electrophysiological properties, cell morphology, and molecular identity,interneurons could be classified into various subgroups. In this study, we investigated the density and laminar distribution of different interneuron types and the coexpression of molecular markers in epileptic human cortex.We found that parvalbumin(PV) and somatostatin(SST)neurons were distributed in all cortical layers except layer I, while tyrosine hydroxylase(TH) and neuropeptide Y(NPY) were abundant in the deep layers and white matter.Cholecystokinin(CCK) neurons showed a high density in layers IV and VI. Neurons with these markers constituted*7.2%(PV), 2.6%(SST), 0.5%(TH), 0.5%(NPY), and4.4%(CCK) of the gray-matter neuron population. Doubleand triple-labeling revealed that NPY neurons were also SST-immunoreactive(97.7%), and TH neurons were more likely to express SST(34.2%) than PV(14.6%). A subpopulation of CCK neurons(28.0%) also expressed PV, but none contained SST. Together, these results revealed the density and distribution patterns of different interneuron populations and the overlap between molecular markers in epileptic human cortex. | Qiyu Zhu Wei Ke Quansheng He Xiongfei Wang Rui Zheng Tianfu Li Guoming Luan Yue-Sheng Long Wei-Ping Lia Yousheng Shu | 2018 | Neuroscience Bulletin2018，34，6： | 3 |
| 4 | Characterization of an extreme alkaline-stable keratinase from the draft genome of feather-degrading Bacillus sp.JM7 from deep-sea显示文摘Bacillus sp. JM7, a strain isolated from the deep-sea of the South China Sea, was found to efficiently degrade 79.4% native chicken feather within 30 h. Scanning electron microscopy analysis showed that JM7 strain could gradually degrade feather by modifying the microstructure of feather keratin. A total of 25 protease genes were predicted from the draft genome of JM7 strain, among which a predicted subtilisin-like serine protease(designated as Ker02562) was further characterized for its keratinolytic activity. The recombinant Ker02562 functioned at a wide range of temperatures from 30℃ to 60℃, with an optimum at 40–50℃. Ker02562 was highly active at various pHs ranging from 5.0 to 13.0, with a maximum activity observed at pH 7.0–9.0. Remarkably, recombinant Ker02562 was stable in extreme alkaline environments(pH 10–13), which was much better than most other reported keratinases. Collectively, these favorable properties could make Bacillus sp. JM7 and Ker02562 attractive to be applied in the detergent formulation and feather bioconversion. | Min Jin Chen Chen Xiongfei He Runying Zeng | 2019 | Acta Oceanologica Sinica2019，38，2： | 2 |

| 6 | Emission-Tunable Nanofluorophores through Self-assembly of Amphiphilic Block Copolymers:toward Application in Cell Imaging显示文摘Comprehensive Summary Nanofluorophores based on aggregation-induced emission(AIE)dyes have recently received considerable attention because of their unique optical properties and biocompatibility.In this work,we report an emission-tunable nanofluorophore constructed by the self-assembly of an amphiphilic block copolymer(denoted by PTN).The diblock copolymer was synthesized by RAFT polymerization.A polyethylene glycol-based trithiocarbonate was employed as the macromolecular chain transfer agent,and a near-infrared emitting tetraphenylethylene derivative with a vinyl terminal group was designed as the monomer.The block copolymers self-assembled in an aqueous solution to form nanospheres,which showed near-infrared emission at approximately 720 nm with a significant Stokes shift of approximately 260 nm.Furthermore,nanofluorophores have excellent biocompatibility,photostability,and pH-independent emission-tunable properties,and were successfully applied to label HeLa cells for fluorescence imaging. | Shensong Zhang Shuang Qi Xiongfei He Pan Xu Bo Song | 2023 | Chinese Journal of Chemistry2023，41，8： | 0 |
