| 1 | Laparoscopic Partial Nephrectomy With Segmental Renal Artery Clamping:Technique and Clinical Outcomes显示文摘Background:Warm ischemic injury is one of the most important factors affecting renal function in partial nephrectomy(PN).The technique of segmental renal artery clamping emerges as an alternative to conventional renal artery clamping for renal hilar control.Objective:To evaluate the feasibility and efficiency of laparoscopic PN(LPN) with segmental renal artery clamping in comparison with the conventional technique.Design,setting,and participants:A total of 75 patients underwent LPN from June 2007 to November 2009.All patients had T1a or T1b tumor in one kidney and a normal contralateral kidney.Thirty-seven patients underwent surgeries with main renal artery clamping,and 38 underwent surgeries with segmental artery clamping.Intervention:All procedures were performed by the same laparoscopic surgeon.Measurements:Blood loss,operation time,warm ischemia(WI) time,and complications affected renal function before and after operation were recorded.Results and limitations:All LPNs were completed without conversion to open surgery or nephrectomy.The novel technique slightly increased WI time(p < 0.001) and intraoperative blood loss(p = 0.006),while it provided better postoperative affected renal function(p < 0.001) compared with the conventional technique.The total complication rate was 12%.Among the 38 cases where segmental renal artery clamping was performed,7 had to convert to the conventional method.Tumor size and location influenced the number of clamped segmental arteries.Long-term postoperative renal function is still awaited.Conclusions:LPN with segmental artery clamping is safe and feasible in clinical practice.It minimizes the intraoperative WI injury and improves early postoperative affected renal function compared with main renal artery clamping.(C) 2010 European Association of Urology.Published by Elsevier B.V.All rights reserved. | Shao,P.F.

| 3 | Massive individual orbital angular momentum channels for multiplexing enabled by Dammann gratings显示文摘Data transmission rates in optical communication systems are approaching the limits of conventional multiplexing methods.Orbital angular momentum(OAM)in optical vortex beams offers a new degree of freedom and the potential to increase the capacity of free-space optical communication systems,with OAM beams acting as information carriers for OAM division multiplexing(OAM-DM).We demonstrate independent collinear OAM channel generation,transmission and simultaneous detection using Dammann optical vortex gratings(DOVGs).We achieve 80/160 Tbit s^(-1) capacity with uniform power distributions along all channels,with 1600 individually modulated quadrature phase-shift keying(QPSK)/16-QAM data channels multiplexed by 10 OAM states,80 wavelengths and two polarizations.DOVG-enabled OAM multiplexing technology removes the bottleneck of massive OAM state parallel detection and offers an opportunity to raise optical communication systems capacity to Pbit s^(-1) level. | Ting Lei Meng Zhang Yuru Li Ping Jia Gordon Ning Liu Xiaogeng Xu Zhaohui Li Changjun Min Jiao Lin Changyuan Yu Hanben Niu Xiaocong Yuan | 2015 | Light(Science & Applications)2015,4,1: | 47 |

| 5 | Formation and destruction processes of upper Sinian oil-gas pools in the Dingshan-Lintanchang structural belt, southeast Sichuan Basin, China显示文摘The lower Cambrian Niutitang Formation hydrocarbon source rocks at the Dingshan-Lintanchang structure in the southeast Sichuan Basin were of medium-good quality with two excellent hydrocarbon-generating centers developed in the periphery areas, with a possibility of forming a medium to large-sized oil-gas field. Good reservoir rocks were the upper Sinian (Dengying Formation) dolomites. The mudstone in the lower Cambrian Niutitang Formation with a good sealing capacity was the cap rock. The widely occurring bitumen in the Dengying Formation indicates that a paleo oil pool was once formed in the study area. The first stage of paleo oil pool formation was maturation of the lower Cambrian source rocks during the late Ordovician. Hydrocarbon generation from the lower Cambrian source rocks stopped due to the Devonian-Carboniferous uplifting. The lower Cambrian source rocks then restarted generation of large quantities of hydrocarbons after deposition of the middle Permian sediments. This was the second stage of the paleo oil pool formation. The oil in the paleo oil pool began to crack during the late Triassic and a paleo gas pool was formed. This paleo gas pool was destroyed during the Yanshan-Himalayan folding, uplifting and denudation. Bitumen can be widely seen in the Dengying Formation in wells and outcrops in the Sichuan Basin and its periphery areas. This provides strong evidence that the Dengying Formation in the Sichuan Basin and its periphery areas was once an ultra-large structural-lithologic oil-gas field, which was damaged during the Yanshan-Himalayan period. | Liu Shugen Zhang Zhijing Huang Wenming Wang Guozhi Sun Wei Xu Guosheng Yuan Haifeng Zhang Changjun Deng Bin | 2010 | Petroleum Science2010,7,3: | 20 |
| 6 | Hydrothermal Dolomite in the Upper Sinian (Upper Proterozoic) Dengying Formation, East Sichuan Basin, China显示文摘Hydrothermal Dolomite(HTD) is present in the Upper Sinian(Upper Proterozoic) Dengying Formation, east Sichuan Basin, China. The strata are comprised by primary dolomite. The HTD has various textures, including zebra dolomite, subhorizontal sheet-like cavities filled by saddle dolomite and breccias cemented by saddle dolomites as well occur as a fill of veins and fractures. Also co-occur MVT type lead-zinc ores in the study area. The δ13C and δ18O isotopes of HTD in the Upper Sinian Dengying Formation are lighter than those of the host rocks, while 87Sr/86 Sr is higher. The apparent difference in carbon, oxygen and strontium isotopes, especially the large difference in 87Sr/86 Sr isotopes ratio indicate crystallization from hot basinal and/or hydrothermal fluids. Saddle dolomite was precipitated at temperatures of 270-320°C. The diagenetic parasequences of mineral assemblage deposited in the Dengying Formation are:(1) dolomite host rock →sphalerite-galena-barite-fluorite;(2) dolomite host rock →saddle dolomite →quartz;(3) dolomite host rock → saddle dolomite→bitumen;(4) dolomite host rock → saddle dolomite → barite. The mean chemical composition of the host dolomite matrix and HTD didn't change much during hydrothermal process. The fluids forming the HTDs in the Dengying Formation were mixtures of freshwater from the unconformity at the top of Sinian, fluids from diagenetic compaction and hydrocarbon generation & expulsion from the Lower Cambrian Niutitang Formation mudstones or the Doushantuo Formation silty mudstones, and hydrothermal fluids from the basement. The hydrocarbon reservoirs associated with the HTD were mostly controlled by the basement faults and fractures and karsting processes at the unconformity separating Sinian and Cambrian strata. The hydrocarbon storage spaces of HTD included dissolved cavities and intercrystalline pores. Dissolution cavities are extensive at the top of Dengying Formation, up to about 46 m below the unconformity between Sinian and Cambrian and were generated mainly during karstification. Hydrothermal alteration enhanced the reservoir property of the Dengying Formation dolomites with 3%-5% increase in porosity. No agreement has been reached why zebra dolomite occurs only in the Upper Sinian strata, which would indicate that HTD mineralization occurred during two different periods, each of them related to major extensional tectonic event. The early one related to the Xingkai taphrogenesis(Z2-?1)and the later one to the Emei taphrogenesis(D2-T2). But, all the data from saddle dolomite suggest that the predominant crystallization occurred during the latter event. | LIU Shugen HUANG Wenming JANSA Luba F.

| 8 | Effect of Laser Welding Process Parameters on Microstructure and Mechanical Properties on Butt Joint of New Hot-Rolled Nano-scale Precipitation-Strengthened Steel显示文摘A 4 kW fiber laser was chosen to weld the new hot-rolled nano-scale precipitation-strengthened steel with a thickness of 4.5 mm. The effect of laser power, defocusing distance, and welding speed on the welded joint appearance was examined, and the microstructure and mechanical properties on the typical butt joints were investigated. Results showed that increasing laser welding power may cause faster downward flow of molten metal to produce greater root humping. With the welding speed increasing, the average welding seam(WS) width decreased, and the average WS and heat-affected zone(HAZ) hardness increased. The microstructures of WS, fusion line, and coarse grain heat-affected zone were lath martensite, but the growth direction of the original austenite grain boundaries was significantly different. The microstructures of fine grain heat-affected zone were ferrite and martensite, and the microstructure of mixed grain heataffected zone contained ferrite, massive M/A island, and a small amount of martensite. The micro-hardness values of WS,HAZ, and base metal(BM) were 358, 302, and 265 HV, respectively. The butt joint fracture at the BM far from the WS and the welded joint tensile strength are observed to follow proportional relationship with hardness. | Min Zhang Xiaonan Wang Guangjiang Zhu Changjun Chen Jixin Hou Shunhu Zhang Hemin Jing | 2014 | Acta Metallurgica Sinica(English Letters)2014,27,3: | 10 |
| 9 | Effect of total aluminum concentration on the formation and transformation of nanosized Al_(13) and Al_(30) in hydrolytic polymeric aluminum aqueous solutions显示文摘Influence of total aluminum concentration (CAlT) on the generation and transformation of nanosized Al13 and Al30 in hydrolytic polyaluminum aqueous solutions was in-vestigated using high field 27Al NMR and time-developed Al-Ferron complex colorimetry. When prepared at the opti-mal basicity (B) of Al13 generation and 80℃, the Al13 species in polyaluminum solution tends to further polymerize and convert to Al30 and higher polymers when CAlT >0.2 mol·L?1, but Al13 does not convert to Al30 quantificationally, as the formation of Alu from Al13 and Al30 is accelerated in the same way. The conversion rate of Al13 is accelerated by the in-crease in CAlT. When CAlT >0.75 mol·L?1, Al13 content de-creases rapidly, and Al30 content increases continuously and becomes the dominant nanometer polynuclear aluminum species. Alm is one of prerequisites of Al13 conversion to Al30. When CAlT increases and B reduces, the polymerization rate between Al13 and Alm increases, and at the same time, the dissociation reaction rate of Al13 and Al30 by H+ also increases. The latter becomes the dominant reaction in polyaluminum solution with low B value, so Al30 decreases with the increas-ing CAlT. The hydrolytic polyaluminum solution with Al13 content beyond 80% can only be prepared under the condi-tion of CAlT<0.5 mol·L?1 and optimal B value. | CHEN Zhaoyang LIU Changjun LUAN Zhaokun ZHANG Zhongguo LI Yanzhong JIA Zhiping | 2005 | Chinese Science Bulletin2005,50,18: | 8 |
| 10 | Ultra-broadband on-chip twisted light emitter for optical communications显示文摘On-chip twisted light emitters are essential components of orbital angular momentum(OAM)communication devices1,2.These devices address the growing demand for high-capacity communication systems by providing an additional degree of freedom for wavelength/frequency division multiplexing(WDM/FDM).Although whispering-gallery-mode-enabled OAM emitters have been shown to possess some advantages3–5,such as compactness and phase accuracy,their inherent narrow bandwidths prevent them from being compatible with WDM/FDM techniques.Here,we demonstrate an ultra-broadband multiplexed OAM emitter that utilizes a novel joint path-resonance phase control concept.The emitter has a micron-sized radius and nanometer-sized features.Coaxial OAM beams are emitted across the entire telecommunication band from 1,450 to 1,650 nm.We applied the emitter to an OAM communication with a data rate of 1.2 Tbit/s assisted by 30-channel optical frequency combs(OFCs).The emitter provides a new solution to further increase capacity in the OFC communication scenario. | Zhenwei Xie Ting Lei Fan Li Haodong Qiu Zecen Zhang Hong Wang Changjun Min Luping Du Zhaohui Li Xiaocong Yuan | 2018 | Light(Science & Applications)2018,7,1: | 7 |
| 11 | New innovations in pavement materials and engineering:A review on pavement engineering research 2021显示文摘Sustainable and resilient pavement infrastructure is critical for current economic and environmental challenges.In the past 10 years,the pavement infrastructure strongly supports the rapid development of the global social economy.New theories,new methods,new technologies and new materials related to pavement engineering are emerging.Deterioration of pavement infrastructure is a typical multi-physics problem.Because of actual coupled behaviors of traffic and environmental conditions,predictions of pavement service life become more and more complicated and require a deep knowledge of pavement material analysis.In order to summarize the current and determine the future research of pavement engineering,Journal of Traffic and Transportation Engineering(English Edition)has launched a review paper on the topic of'New innovations in pavement materials and engineering:A review on pavement engineering research 2021'.Based on the joint-effort of 43 scholars from 24 well-known universities in highway engineering,this review paper systematically analyzes the research status and future development direction of 5 major fields of pavement engineering in the world.The content includes asphalt binder performance and modeling,mixture performance and modeling of pavement materials,multi-scale mechanics,green and sustainable pavement,and intelligent pavement.Overall,this review paper is able to provide references and insights for researchers and engineers in the field of pavement engineering. | JTTE Editorial Office Jiaqi Chen Hancheng Dan Yongjie Ding Yangming Gao Meng Guo Shuaicheng Guo Bingye Han Bin Hong Yue Hou Chichun Hu Jing Hu Ju Huyan Jiwang Jiang Wei Jiang Cheng Li Pengfei Liu Yu Liu Zhuangzhuang Liu Guoyang Lu Jian Ouyang Xin Qu Dongya Ren Chao Wang Chaohui Wang Dawei Wang Di Wang Hainian Wang Haopeng Wang Yue Xiao Chao Xing Huining Xu Yu Yan Xu Yang Lingyun You Zhanping You Bin Yu Huayang Yu Huanan Yu Henglong Zhang Jizhe Zhang Changhong Zhou Changjun Zhou Xingyi Zhu | 2021 | Journal of Traffic and Transportation Engineering(English Edition)2021,8,6: | 7 |

| 13 | All-optical manipulation of micrometer-sized metallic particles显示文摘Optical traps use focused laser beams to generate forces on targeted objects ranging in size from nanometers to micrometers. However, for their high coefficients of scattering and absorption, micrometer-sized metallic particles were deemed non-trappable in three dimensions using a single beam. This barrier is now removed. We demonstrate, both in theory and experiment, three-dimensional(3D) dynamic all-optical manipulations of micrometersized gold particles under high focusing conditions. The force of gravity is found to balance the positive axial optical force exerted on particles in an inverted optical tweezers system to form two trapping positions along the vertical direction. Both theoretical and experimental results confirm that stable 3D manipulations are achievable for these particles regardless of beam polarization and wavelength. The present work opens up new opportunities for a variety of in-depth research requiring metallic particles. | YUQUAN ZHANG XIUJIE Dou YANMENG DAI XIANYOU WANG CHANGJUN MIN AND XIAOCONG YUAN | 2018 | Photonics Research2018,6,2: | 6 |
| 14 | Variation and selection analysis of Pinus koraiensis clones in northeast China显示文摘Understanding genetic variation is important for efficiently selecting excellent clones and utilizing genetic resources during tree breeding. We investigated 16 growth traits of 50 32-year-old Pinus koraiensis clones. Analyses of variance showed that all the test traits differed significantly among clones. Average height, diameter at breast height(DBH), and volume of all clones were 10.41 m, 21.30 cm,and 0.148 m3, respectively. Phenotypic coefficients of variation and repeatabilities of traits ranged from 4.37 to48.03% and from 0.013 to 0.900, respectively. There exists significant positive correlations among heights, diameter at different heights(1.3, 3.0, 5.0 m), and volumes; genetic correlation was close to phenotype correlation. Using four growth traits(height, DBH, volume, average crown width)as indices for a comprehensive evaluation, five clones(PK11, PK 19, PK 04, PK 14, and PK 28), whose traits scored in the top 10%, were selected as elite clones. For these clones,genetic gains in height, DBH, volume and crown height were 8.58, 13.02, 32.72 and 3.83%, respectively. These results provide important information for improving P.koraiensis breeding programs. | Deyang Liang Changjun Ding Guanghao Zhao Weiwei Leng Min Zhang Xiyang Zhao Guanzheng Qu | 2018 | Journal of Forestry Research2018,29,3: | 6 |
| 15 | Reservoir Characteristics and Preservation Conditions of Longmaxi Shale in the Upper Yangtze Block, South China显示文摘The Upper Ordovician-Lower Silurian Longmaxi Shale in the Upper Yangtze block represents one of the most important shale gas plays in China. The shale composition,porosity,organic thermal maturity,and methane sorption were investigated at the Qilongcun section in the Dingshan area,southeastern Sichuan Basin. The results show that the Upper Ordovician-Lower Silurian Longmaxi Shale contains:(1) sapropelic I organic matter;(2) a 40-m thick bedded sequence where total organic carbon(TOC) content is > 2%;(3) a 30-m thick layer at the base of the Longmaxi Shale with a brittle mineral content higher than 50%; and(4) a mean methane adsorption capacity of 1.80 cm^3/g(7 MPa pressure). A positive correlation between TOC and sorbed gas indicates that organic matter content exerts an important control on methane storage capacity. Based on the analysis of the shale reservoir characteristics,the lower member of the Longmaxi Shale can thus be considered a favorable stratum for shale gas exploration and exploitation. It has similar reservoir characteristics with the Longmaxi Shale in the Jiaoshiba area tested with a high-yield industrial gas flow. However,based on tectonic analysis,differences in the level of industrial gas flow between the low-yield study area and the high-yield Jiaoshiba area may result from different tectonic preservation conditions. Evidence from these studies indicates the shale gas potential of the Longmaxi Shale is constrained by the reservoir and preservation conditions. | RAN Bo LIU Shugen Luba JANSA SUN Wei YANG Di WANG Shiyu YE Yuehao Christopher XIAO ZHANHG Jian ZHAI Cangbo LUO Chao ZHANG Changjun | 2016 | Acta Geologica Sinica(English Edition)2016,90,6: | 6 |

| 17 | Enhancing plasmonic trapping with a perfect radially polarized beam显示文摘Strong plasmonic focal spots, excited by radially polarized light on a smooth thin metallic film, have been widely applied to trap various micro-and nano-sized objects. However, the direct transmission part of the incident light leads to the scattering force exerted on trapped particles, which seriously affects the stability of the plasmonic trap.Here we employ a novel perfect radially polarized beam to solve this problem. Both theoretical and experimental results verify that such a beam could strongly suppress the directly transmitted light to reduce the piconewton scattering force, and an enhanced plasmonic trapping stiffness that is 2.6 times higher is achieved in experiments.The present work opens up new opportunities for a variety of research requiring the stable manipulations of particles. | xianyou wang yuquan zhang yanmeng dai changjun min xiaocong yuan | 2018 | Photonics Research2018,6,9: | 5 |

| 20 | A Streptococcus suis serotype 2 caused streptococcal toxic shock syndrome(STSS) in a patient显示文摘Streptococcus suis(S.suis)is a Gram-positive,facultatively anaerobic coccus that has been implicated as the cause of a wide range of clinical disease syndromes in swine and other domestic animals.S.suis has also been implicated in disease in humans,especially among abattoir workers,swine and pork handlers.Here we report a case of streptococcal toxic shock syndrome(STSS)caused by S.suis in a 59-year-old man.Despite of intensive treatment,the patient died of shock with multiple organ failure 14 h after admission.One bacterial isolate obtained from blood culture was identified to the species level by biochemical tests and serological tests as S.suis serotype 2.Identification was confirmed by PCR amplification of genes encoding 16sRNA of S.suis and the capsule of S.suis serotype 2(cps 2J).Genes encoding virulence factors were also detected.An investigation to identify the source of S.suis revealed that several days before admission the affected man had been handling sick pigs or their meat.Transmission may occur through breaks in the skin of feet with tinea due to that no measures for personal protection was taken.This case should highten awareness of the potential for occupational exposure and human infection with S.suis. | Yefei Zhu Zhongmin Tan Lingyang Zhu Hongxing Pan Xuejun Zhang Lei Xu Huimin Qian Ling Gu Xun Ye Chen Dong Changjun Bao Rongqiang Zhu Fengcai Zhu Hua Wang | 2008 | Journal of Nanjing Medical University2008,22,5: | 3 |
