1Spinal cord biological safety of image-guided radiation therapy versus conventional radiation therapy显示文摘Tumor models were simulated in purebred Beagles at the T9-10 levels of the spinal cord and treated with spinal image-guided radiation therapy or conventional radiation therapy with 50 or 70 Gy total radiation. Three months after radiation, neuronal injury at the T9-10 levels was observed, including reversible injury induced by spinal image-guided radiation therapy and apoptosis induced by conventional radiation therapy. The number of apoptotic cells and expression of the proapoptotic protein Fas were significantly reduced, but expression of the anti-apoptotic protein heat shock protein 70 was significantly increased after image-guided radiation therapy compared with the conventional method of the same radiation dose. Moreover, the spinal cord cell apoptotic index positively correlated with the ratio of Fas/heat shock protein 70. These findings indicate that 3 months of radiation therapy can induce a late response in the spinal cord to radiation therapy; image-guided radiation therapy is safer and results in less neuronal injury compared with conventional radiation therapy.Wanlong Xu Xilinbaoleri Hao Liu Ruozheng Wang Jingping Bai 2012Neural Regeneration Research2012,7,35:23
2Review on carbon storage estimation of forest ecosystem and applications in China显示文摘Background:The accuracy in estimating forest ecosystem carbon storage has drawn extensive attention of researchers in the field of global climate change.However,incomparable data sources and various estimation methods have led to significant differences in the estimation of forest carbon storage at large scales.Methods:In this study,we reviewed fundamental types of forest carbon storage estimation methods and their applications in China.Results:Results showed that the major forest carbon storage estimation methods were classified into 3 major categories and 15 subcategories focusing on vegetation carbon storage estimation,soil carbon storage estimation,and litter carbon storage estimation,respectively.The application in China showed that there have been 3 development stages of research in China since the 1990s.Studies of forest carbon storage estimation in province scales were conducted more frequently in the northeastern,eastern and southwestern provinces such as Zhejiang,Heilongjiang and Sichuan with high forest coverage or large forest area.Inventory-based methods,soil type method,and biomass model were the main forest estimation methods used in China,focusing on vegetation,soil and litter carbon storage estimation respectively.Total forest carbon storage of China was approximate 28.90 Pg C,and the average vegetation carbon density(42.04±5.39 Mg·ha?1)was much lower than that of the whole world(71.60 Mg·ha?1).Vegetation carbon density from average biomass method was the highest(57.07 Mg·ha?1)through comparing nine types of vegetation carbon storage estimation methods applied during 1989 to 1993.Conclusions:Many studies on forest carbon storages have been carried out in China at patch scales or regional scales.These efforts enabled the research of forest carbon storage to reach a relatively advanced stage.Meanwhile,the accumulation of massive research data provides the basis for subsequent research work.Some challenges are also existing.This review could provide a reference for more accurate estimation of forest carbon storage in the future.Wanlong Sun Xuehua Liu 2020Forest Ecosystems2020,7,1:12

4Nitrogen Biological Cycle Characteristics of Seepweed(Suaeda salsa) Wetland in Intertidal Zone of Huanghe(Yellow) River Estuary显示文摘From April 2008 to November 2009,the nitrogen(N) cycle of plantsoil system in seepweed(Suaeda salsa) wetland in the intertidal zone of the Huanghe(Yellow) River estuary was studied.Results showed that soil N had sig-nificant seasonal fluctuations and vertical distribution,and the net N mineralization rates in topsoil were significantly different in growing season(p < 0.01).The N/P ratio(9.87 ± 1.23) of S.salsa was less than 14,indicating that plant growth was limited by N.The N accumulated in S.salsa litter at all times during decomposition,which was ascribed to the N immobilization by microbes from the environment.Soil organic N was the main N stock of plant-soil system,accounting for 97.35% of the total N stock.The N absorption and utilization coefficients of S.salsa were very low(0.0145 and 0.3844,respectively),while the N cycle coefficient was high(0.7108).The results of the N turnovers among compartments of S.salsa wetland showed that the N uptake amount of aboveground part and root were 7.764 g/m2and 4.332 g/m2,respectively.The N translocation amounts from aboveground part to root and from root to soil were 3.881 g/m2 and 0.626 g/m2,respectively.The N translocation amount from aboveground living body to litter was 3.883 g/m2,the annual N return amount from litter to soil was more than 0.125(-) g/m2(minus represented immobilization),and the net N mineralization amount in topsoil(0-15 cm) in growing season was 1.190 g/m2.The assessment of N biological cycle status of S.salsa wetland indicated that N was a very important limiting factor and the ecosystem was situated in unstable and vulnerable status.The S.salsa was seemingly well adapted to the low-nutrient status and vulnerable habitat,and the N quantitative relationships determined in the compartment model might provide scientific base for us to reveal the special adaptive strategy of S.salsa to the vulnerable habitat in the following studies.SUN Zhigao MOU Xiaojie SUN Jingkuan SONG Hongli YU Xiang WANG Lingling JIANG Huanhuan SUN Wanlong SUN Wenguang 2012Chinese Geographical Science2012,22,1:9
5CAD Model-Based Intelligent Inspection Planning for Coordinate Measuring Machines显示文摘As the market competition among enterprises grows intensively and the demand for high quality products increases rapidly, product quality inspection and control has become one of the most important issues of manufacturing, and improving the efficiency and accuracy of inspection is also one of problems which enterprises must solve. It is particularly important to establish rational inspection planning for parts before inspecting product quality correctly. The traditional inspection methods have been difficult to satisfy the requirements on the speed and accuracy of modern manufacturing, so CAD-based computer-aided inspection planning (CAIP) system with the coordinate measuring machines (CMM) came into being. In this paper, an algorithm for adaptive sampling and collision-free inspection path generation is proposed, aiming at the CAD model-based inspection planning for coordinate measuring machines (CMM). Firstly, using the method of step adaptive subdivision and iteration , the sampling points for the specified number with even distribution will be generated automatically. Then, it generates the initial path by planning the inspection sequence of measurement points according to the values of each point's weight sum of parameters, and detects collision by constructing section lines between the probe swept-volume surfaces and the part surfaces, with axis-aligned bounding box (AABB) filtering to improve the detection efficiency. For collided path segments, it implements collision avoidance firstly aiming at the possible outer-circle features, and then at other collisions, for which the obstacle-avoiding movements are planned with the heuristic rules, and combined with a designed expanded AABB to set the obstacle-avoiding points. The computer experimental results show that the presented algorithm can plan sampling points' locations with strong adaptability for different complexity of general surfaces, and generate efficient optimum path in a short time and avoid collision effectively.DONG Yude LIU Daxin ZHAO Han WANG Wanlong WU Juan 2011Chinese Journal of Mechanical Engineering2011,24,4:8

8Three-dimensional conformal intensity-modulated radiation therapy of left femur foci does not damage the sciatic nerve显示文摘During radiotherapy to kill femoral hydatid tapeworms,the sciatic nerve surrounding the focus can be easily damaged by the treatment.Thus,it is very important to evaluate the effects of radiotherapy on the surrounding nervous tissue.In the present study,we used three-dimensional,conformal,intensity-modulated radiation therapy to treat bilateral femoral hydatid disease in Meriones meridiani.The focus of the hydatid disease on the left femur was subjected to radiotherapy(40 Gy) for 14 days,and the right femur received sham irradiation.Hematoxylin-eosin staining,electron microscopy,and terminal deoxynucleotidyl transferase-d UTP nick end labeling assays on the left femurs showed that the left sciatic nerve cell structure was normal,with no obvious apoptosis after radiation.Trypan blue staining demonstrated that the overall protoscolex structure in bone parasitized with Echinococcus granulosus disappeared in the left femur of the animals after treatment.The mortality of the protoscolex was higher in the left side than in the right side.The succinate dehydrogenase activity in the protoscolex in bone parasitized with Echinococcus granulosus was lower in the left femur than in the right femur.These results suggest that three-dimensional conformal intensity-modulated radiation therapy achieves good therapeutic effects on the secondary bone in hydatid disease in Meriones meridiani without damaging the morphology or function of the sciatic nerve.Wanlong Xu Xibin Zhao Qing Wang Jungang Sun Jiangbo Xu Wenzheng Zhou Hao Wang Shigui Yan Hong Yuan 2014Neural Regeneration Research2014,9,20:6
9SOME NEW RESULTS ON THE CONFIDENCELIMITS FOR RELIABILITY PARAMETERS IN THECASE OF NO FAILURES显示文摘In reliability tests, Type I censored data are common. For products of high quality, real life length is much longer than the censoring time. A group of items of some kind of product are put into reliability experiment. In case every item is censored,there is no failure. We refer to such data as No Failures. We construct lower confidence limits for life characteristics (such as average life, reliability, reliable span). This is done under the assumption of Weibull distribution, Lognormal distribution and nonparametric distribution family in the case of no failures.SUN Wanlong CHEN Jiading (Department of Probability and Statistics, Peking University, Beijing 100871, China) 1999Systems Science and Mathematical Sciences1999,12,1:5
10Improving the Local Sheep in Gansu via Crossing with Introduced Sheep Breeds Dorset and Borderdale显示文摘In order to improve the meat performance of local sheep in Gansu Province,Dorset and Borderdale were introduced to crossbreed with local sheep which were Tan sheep,Small-tail Han sheep and Mongolia sheep. The offspring under different crossbreeding combinations were sampled randomly at the different growing stage to measure their growth traits so as to select optimize the crossbreeding mode. The results indicated that,for the same crossbreeding mode,the growth rate of progeny was in order F3> F2> F1; for the F3 progeny,the combinations Dorset- Borderdale- Small tail Han sheep and Dorset- Borderdale- Mongolia sheep gave a higher growth rate,with a body weight of 1. 57%,3. 17%,8. 23%,1. 15% higher in male and female individuals than the counterparts of Dorset and Tan sheep and Small tail Han sheep; for the F2 progeny,the combinations Dorset- Borderdale- Small tail Han sheep and Dorset- Borderdale- Mongolia sheep also gave a higher growth rate,with a body weight of 2. 15%,4. 53%,9. 21% and 2. 75% higher in male and female individuals than the counterparts of Dorset and Tan sheep and Small tail Han sheep; for the F1 progeny,the combination Borderdale and Small tail Han sheep assumed a higher growth rate,with a body weight of 3. 23%,6. 07%,7. 42% and 8. 66% higher in male and female individuals than the counterparts of Borderdale- Mongolia sheep and Tan sheep- Small tail Han sheep,respectively. Therefore,in the Small-tail Han sheep and Mongolia sheep producing regions,the F2 or F3progeny bred by using Dorset or Borderdale sheep as male parent to cross with local breeds,or the hybrid lambs of Small-tail Han sheep and Borderdale sheep as highly qualified commodity,would produce significant economic benefit. Moreover,the novel breeds obtained by crossing were the valuable genetic resource for breeding meat sheep.Sun Xiaoping Liu Jianbin Zhang Wanlong Lang Xia Yang Bohui Guo Jian Feng Ruilin 2014Animal Husbandry and Feed Science2014,6,5:3
11Hybrid Dirac semimetal-based photodetector with efficient low-energy photon harvesting显示文摘Despite the considerable effort,fast and highly sensitive photodetection is not widely available at the low-photon-energy range(~meV)of the electromagnetic spectrum,owing to the challenging light funneling into small active areas with efficient conversion into an electrical signal.Here,we provide an alternative strategy by efficiently integrating and manipulating at the nanoscale the optoelectronic properties of topological Dirac semimetal PtSe_(2)and its van der Waals heterostructures.Explicitly,we realize strong plasmonic antenna coupling to semimetal states near the skin-depth regime(λ/10^(4)),featuring colossal photoresponse by in-plane symmetry breaking.The observed spontaneous and polarization-sensitive photocurrent are correlated to strong coupling with the nonequilibrium states in PtSe_(2)Dirac semimetal,yielding efficient light absorption in the photon range below 1.24 meV with responsivity exceeding∼0.2 A/W and noise-equivalent power(NEP)less than~38 pW/Hz^(0.5),as well as superb ambient stability.Present results pave the way to efficient engineering of a topological semimetal for high-speed and low-energy photon harvesting in areas such as biomedical imaging,remote sensing or security applications.Lin Wang Li Han Wanlong Guo Libo Zhang Chenyu Yao Zhiqingzi Chen Yulu Chen Cheng Guo Kaixuan Zhang Chia-Nung Kuo Chin Shan Lue Antonio Politano Huaizhong Xing Mengjie Jiang Xianbin Yu Xiaoshuang Chen Wei Lu 2022Light(Science & Applications)2022,11,3:2
12Does diffusion tensor data reflect pathological changes in the spinal cord with chronic injury?显示文摘Magnetic resonance diffusion tensor imaging has been shown to quantitatively measure the early pathological changes in chronic cervical spondylotic myelopathy.In this study,a novel spongy polyurethane material was implanted in the rat C3–5epidural space to establish a rat model of chronic cervical spondylotic myelopathy.Diffusion tensor data were used to predict pathological changes.Results revealed that the fractional anisotropy value gradually decreased at 4,24,and 72 hours and1 week after injury in rat spinal cord,showing a time-dependent manner.Average diffusion coefficient increased at 72 hours and 1 week after implantation.Hematoxylin-eosin staining and Luxol-fast-blue staining exhibited that the number of neurons in the anterior horn of the spinal cord gray matter and the nerve fiber density of the white matter gradually reduced with prolonged compression time.Neuronal loss was most significant at 1 week after injury.Results verified that the fractional anisotropy value and average diffusion coefficient reflected the degree of pathological change in the site of compression in rat models at various time points after chronic spinal cord compression injury,which potentially has a reference value in the early diagnosis of chronic cervical spondylotic myelopathy.Erjian Lin Houqing Long Guangsheng Li Wanlong Lei 2013Neural Regeneration Research2013,8,36:2

14Study on Flow Characteristics of a Turbulent Boundary Layer and Vortex Structure of High Pressure Guide Vanes in SCO_2 Turbines显示文摘In order to further understand the aerothermodynamic performance and flow loss mechanism of SCO_2 turbines, RANS equations and an SST Turbulence Model were chosen for a numerical study on the secondary flow and vortex structure of cascades using the commercial software CFX. The dimensionless vorticity analysis method was used to study the flow characteristics of the logarithmic layer and viscous sublayer in high pressure guide vane cascades. The new vortex structure and formation mechanism of the vortices were given and analyzed. Simulation results indicated that during the motion of the boundary layer in the cascades, the logarithmic layer and viscous sublayer obtain the different rotational direction vorticity, respectively. The endwall logarithmic layer and pressure side leg of the horseshoe votex gradually develop into the passage vortex, with the endwall viscous sublayer gradually developing into the corner viscous sublayer vortex II and the endwall viscous sublayer vortex I. The endwall viscous sublayer that rolled by the passage vortex is encountered with the upstream-side and radial boundary layer of the vane at the suction separation line, forming the suction separation line vortex beside the passage vortex. A pair of radial transition vortices are formed between the wake and the main stream.HAN Wanlong WANG Yueming FENG Zhenping LI Hongzhi YAO Mingyu ZHANG Yifan 2019Journal of Thermal Science2019,28,3:1
