| 1 | SPECIAL ISSUE: MIGRANT WORKERS IN THE COURSE OF URBANIZATON Wages for migrant workers in the Pearl River Delta: determining factors显示文摘本文通过对珠江三角洲农民工问卷调查资料的回归分析,试图检验在市场转型下的企业制度和社会环境对农民工工资的影响。研究发现,人力资本中的教育年限、本企业工龄等变量对农民工工资有显著的正向影响,年龄和性别也有显著影响;企业制度中的工种对工资有显著影响,表现出明显的等级性。企业所属行业、规模和企业性质对工资没有显著影响,是否签订劳动合同和缺工情况同样如此。社会资本变量和社会环境变量对农民工工资水平没有显著影响。文章由此认为,农民工的工资是处于分割的二元劳动力市场一端,是高度市场化的,缺乏企业内部劳动力市场或晋升机制,也少受劳动力市场用工情况变化影响,没有地区性差异,是一个实实在在的、刚性的低工资。 | Liu Linping Zhang Chunni | 2008 | Social Sciences in China2008，29，3： | 6 |
| 2 | Stereotactic body radiation therapy versus radiofrequency ablation in patients with small hepatocellular carcinoma:a systematic review and meta-analysis显示文摘Background:This study aimed to compare the clinical outcomes and toxicity between small hepatocellular carcinoma(HCC)patients treated with stereotactic body radiation therapy(SBRT)and those treated with radiofrequency ablation(RFA).Methods:We searched databases for relevant clinical studies.The primary outcomes of interest were overall survival(OS)at 1 and 2 years,freedom from local progression(FFLP)rate at 2 years,and complications.Results:Five cohorts from 5 retrospective studies and 4,814 patients with HCC were included.Pooled OS at 2 years was significantly lower for SBRT than for RFA[odds ratio(OR):0.63;95%confidence interval(CI):0.51-0.79;P<0.0001],but the pooled FFLP rate at 2 years was higher for SBRT than for RFA(OR:1.66;95%CI:1.05-2.61;P=0.03).In addition,there was no significant difference in the local and liver toxicities of the two treatments.The contradictory conclusion between the OS and FFLP outcome may be attributed to the difference in radiological dose and location,but there were no uniform criteria to illustrate the radiological dose and location in the included studies.Conclusions:SBRT had a higher local control ratio but poorer prognosis than RFA in patients with small HCC.The local toxicity was comparable in both treatments.Further trials should be designed with uniform standards for SBRT and RFA treatments. | Jiawei Hong Linping Cao Haiyang Xie Yuanxing Liu Jun Yu Shusen Zheng | 2021 | Hepatobiliary Surgery and Nutrition2021，10，5： | 5 |
| 3 | Benzene containing polyhydroxyalkanoates homo-and copolymers synthesized by genome edited Pseudomonas entomophila显示文摘Microbial synthesis of functional polymers has become increasingly important for industrial biotechnology.For the first time,it became possible to synthesize controllable composition of poly(3-hydroxyalkanoate)(P3HA)consisting of 3-hydroxydodecanoate(3HDD)and phenyl group on the side-chain when chromosome of Pseudomonas entomophila was edited to weaken itsβ-oxidation.Cultured in the presence of 5-phenylvaleric acid(PVA),the edited P.entomophila produced only homopolymer poly(3-hydroxy-5-phenylvalerate)or P(3HPhV).While copolyesters P(3HPhV-co-3HDD)of 3-hydroxy-5-phenylvalerate(3HPhV)and 3-hydroxydodecanoate(3HDD)were synthesized when the strain was grown on mixtures of PVA and dodecanoic acid(DDA).Compositions of 3HPhV in P(3HPhV-co-3HDD)were controllable ranging from 3%to 32%depending on DDDA/PVA ratios.Nuclear magnetic resonance(NMR)spectra clearly indicated that the polymers were homopolymer of P(3HPhV)and random copolymers of 3HPhV and 3HDD.Their mechanical and thermal properties varied dramatically depending on the monomer ratios.Our results demonstrated the possibility to produce tailor-made,novel functional PHA using the chromosome edited P.entomophila. | SHEN Rui CAI LongWei MENG DeChuan WU LinPing GUO Kai DONG GuoXing LIU Lei CHEN JinChun WU Qiong CHEN GuoQiang | 2014 | Science China(Life Sciences)2014，57，1： | 4 |
| 4 | Single-cell transcriptomic landscape of human blood cells显示文摘High throughput single-cell RNA-seq has been successfully implemented to dissect the cellular and molecular features underlying hematopoiesis.However,an elaborate and comprehensive transcriptome reference of the whole blood system is lacking.Here,we profiled the transcriptomes of 7551 human blood cells representing 32 immunophenotypic cell types,including hematopoietic stem cells,progenitors and mature blood cells derived from 21 healthy donors.With high sequencing depth and coverage,we constructed a single-cell transcriptional atlas of blood cells(ABC) on the basis of both protein-coding genes and long noncoding RNAs(lncRNAs),and showed a high consistence between them.Notably,putative lncRNAs and transcription factors regulating hematopoietic cell differentiation were identified.While common transcription factor regulatory networks were activated in neutrophils and monocytes,lymphoid cells dramatically changed their regulatory networks during differentiation.Furthermore,we showed a subset of nucleated erythrocytes actively expressing immune signals,suggesting the existence of erythroid precursors with immune functions.Finally,a web portal offering transcriptome browsing and blood cell type prediction has been established.Thus,our work provides a transcriptional map of human blood cells at single-cell resolution,thereby offering a comprehensive reference for the exploration of physiological and pathological hematopoiesis. | Xiaowei Xie Mengyao Liu Yawen Zhang Bingrui Wang Caiying Zhu Chenchen Wang Qing Li Yingying Huo Jiaojiao Guo Changlu Xu Linping Hu Aiming Pang Shihui Ma Una Wang Wenbin Cao Shulian Chen Qiuling Li Sudong Zhang Xueying Zhao Wen Zhou Hongbo Luo Guoguang Zheng Erlie Jiang Sizhou Feng Lixiang Chen Lihong Shi Hui Cheng Sha Hao Ping Zhu Tao Cheng | 2021 | National Science Review2021，8，3： | 3 |
| 5 | Cation-vacancy induced Li+ intercalation pseudocapacitance at atomically thin heterointerface for high capacity and high power lithium-ion batteries显示文摘It is challenging to create cation vacancies in electrode materials for enhancing the performance of rechargeable lithium ion batteries (LIBs). Herein, we utilized a strong alkaline etching method to successfully create Co vacancies at the interface of atomically thin Co_(3−x)O_(4)/graphene@CNT heterostructure for high-energy/power lithium storage. The creation of Co-vacancies in the sample was confirmed by high-resolution scanning transmission electron microscope (HRSTEM), X-ray photoelectron spectroscopy (XPS) and electron energy loss near-edge structures (ELNES). The obtained Co_(3−x)O_(4)/graphene@CNT delivers an ultra-high capacity of 1688.2 mAh g^(−1) at 0.2 C, excellent rate capability of 83.7% capacity retention at 1 C, and an ultralong life up to 1500 cycles with a reversible capacity of 1066.3 mAh g^(−1). Reaction kinetic study suggests a significant contribution from pseudocapacitive storage induced by the Co-vacancies at the Co_(3−x)O_(4)/graphene@CNT interface. Density functional theory confirms that the Co-vacancies could dramatically enhance the Li adsorption and provide an additional pathway with a lower energy barrier for Li diffusion, which results in an intercalation pseudocapacitive behavior and high-capacity/rate energy storage. | Ding Yuan David Adekoya Yuhai Dou Yuhui Tian Hao Chen Zhenzhen Wu Jiadong Qin Linping Yu Jian Zhang Xianhu Liu Shi Xue Dou Shanqing Zhang | 2021 | Journal of Energy Chemistry2021，30，11： | 2 |
| 6 | Effects of initial particle gradation and rock content on crushing behaviors of weathered phyllite fills——A case of eastern Ankang section of Shiyan—Tianshui highway,China显示文摘The objective of this paper is to investigate the effects of initial particle gradation and rock content on the crushing behavior(i.e.grain size before and after crushing) of weathered phyllite fills.Compaction tests were conducted on weathered phyllite fills with rock contents of 35%,45%,55%,65% and 75%(by weight).First,the particle size distributions(PSDs) were observed before and after compaction,and then the particle breakage of weathered phyllite fills was analyzed by fractal dimension.Relative fractal dimension was proposed to evaluate the effects of initial rock content and initial gradation on the particle breakage.It was found that the fractal dimension method can well characterize the crushing behaviors of the weathered phyllite fills.The finer the fills were,the more they were compacted.That is,after the first compaction,the relative fractal dimension of the weathered phyllite fills increased as the rock content increased,reaching the values of 0.013,0.016,0.024,0.037 and 0.08,respectively.After the second compaction,these relative fractal dimension values,dominated by the initial particle gradation,became 0.059,0.072,0.052,0.095 and 0.118,respectively.In conclusion,the weathered phyllite fills with 55% rock content exhibited the least breakage and were most suitable for filling the subgrade.Findings in this paper will provide significant guidance for the construction of weathered phyllite filling subgrade in future projects. | Feifei Liu Xuesong Mao Yushuo Fan Linping Wu Wei Victor Liu | 2020 | Journal of Rock Mechanics and Geotechnical Engineering2020，12，2： | 2 |

| 15 | Spatial Distribution and Seasonal Variation of Hypoxic Zone in the Eastern Equatorial Indian Ocean显示文摘The spatial distribution and seasonal variations of the hypoxic zone in the eastern equatorial Indian Ocean were investigated using survey data collected from four cruises from 2013 to 2018.Results showed that hypoxic zone occurred all year round in the eastern equatorial Indian Ocean,and it spread southward in the shape of a double tongue at two depths with one at subsurface centered at a depth of 150 m and the other in intermediate water centered at a depth of 800 m.The southward expansion and maximum thickness of the hypoxic zone were greatest in the spring inter-monsoon and least in the summer monsoon.The hypoxic zone originated from the southward expansion of the hypoxic water in the Bay of Bengal and its spatial distribution was driven by southward output flux of mid-deep(100–1000 m)hypoxic water from the Bay of Bengal.The hypoxia southward expansion was blocked near the equator in the subsurface layer,because of mixing with multiple zonal circulations(e.g.,Wyrtki Jets and the equatorial undercurrent),which meant that the hypoxic zone extended over a smaller area than in the intermediate water.These new findings will contribute to an improved understanding of the hypoxic zone and will contribute to circulation research,particularly about intermediate circulation in the eastern equatorial Indian Ocean. | XIE Linping WANG Baodong XIN Ming WANG Ying SUN Xia WEI Qinsheng LIU Lin YUAN Chao | 2023 | Journal of Ocean University of China2023，22，4： | 0 |
| 16 | Factors associated with dysglycemia and its post-surgical resolution in patients with pheochromocytomas显示文摘Dear Editor,Pheochromocytomas are rare neuroendocrine tumors originating from chromaffin cells in the adrenal medulla(Neumann et al., 2019). A number of case reports and small cohorts have reported the association between dysglycemia and pheochromocytomas(Elenkova et al., 2020;Khatiwada et al., 2020;Krumeich et al., 2021). However, there are few large sample studies reporting the outcomes of dysglycemia in patients with pheochromocytomas after resection. | Lin Zhao Xu Meng Qiongyu Zhang Yi Zhou Ting Zhang Tao Tian Hua Fan Huadong Zhu Yecheng Liu Fang Luo Linping Wang Weixian Yang Xianliang Zhou | 2023 | Science China(Life Sciences)2023，66，2： | 0 |
| 17 | Geological Characteristics and Manifestations of Geological Processes of Sequence Boundaries and Their Vicinities显示文摘This paper discusses the geological characteristics and architectures of sequence boundaries and their vicinities and has proposed a classification scheme for the sequence boundaries, which can thus be grouped into three types and eight categories: type I includes exposed truncated surface, palaeosol surface, palaeokarst surface and exposed surface; type Ⅱ boundaries include structural transitional surface during sea-level fall and transgressive onlap surface; and type Ⅲ includes submarine erosional diagenetic diastem and event surface. A study has been made for the three major boundaries lying between the Permian and pre-Permian, the Permian and Triassic, and the Middle and Lower Triassic respectively in terms of multiple disciplines such as lithostratigraphy, biostratigraphy, magnetostratigraphy and carbon and oxygen isotopic geology. These three boundaries are ascribed to type I , typeⅡ and typeⅢ, respectively. | Xiao Linping Testing Centre of Geotechnical Engineering, Southwest Jiaotong Universityand Zhao YuguangChengdu Institute of Mineral Resources, Chinese Academy of Geological Sciences, Chengdu, Sichuan, 610082 Liu Xinzhu | 1997 | Acta Geologica Sinica(English Edition)1997，71，4： | 0 |
