| 1 | Trabecular Plate Loss and Deteriorating Elastic Modulus of Femoral Trabecular Bone in Intertrochanteric Hip Fractures显示文摘Osteoporotic hip fracture is associated with significant trabecular bone loss,which is typically characterized as low bone density by dual-energy X-ray absorptiometry(DXA)and altered microstructure by micro-computed tomography(μCT).Emerging morphological analysis techniques,e.g.individual trabecula segmentation(ITS),can provide additional insights into changes in plate-like and rod-like trabeculae,two major micro-structural types serving different roles in determining bone strength.Using ITS,we evaluated trabecular microstructure of intertrochanteric bone cores obtained from 23 patients undergoing hip replacement surgery for intertrochanteric fracture and 22 cadaveric controls.Micro-finite element(μFE)analyses were performed to further understand how the abnormalities seen by ITS might translate into effects on bone strength.ITS analyses revealed that,near fracture site,plate-like trabeculae were seriously depleted in fracture patients,but trabecular rod volume was maintained.Besides,decreased plate area and rod length were observed in fracture patients.Fracture patients also showed decreased elastic moduli and shear moduli of trabecular bone.These results provided evidence that in intertrochanteric hip fracture,preferential loss of plate-like trabeculae led to more rod-like microstructure and deteriorated mechanical competence adjacent to the fracture site,which increased our understanding of the biomechanical pathogenesis of hip fracture in osteoporosis. | Ji Wang Bin Zhou Ian Parkinson C.David L.Thomas John G.Clement Nick Fazzalari X.Edward Guo | 2013 | Bone Research2013，1，4： | 4 |

| 6 | 卷云冰晶水平取向的光雷达观测显示文摘在Aberystwyth(52.4°N,4.1°W)利用一个扫描激光雷达系统测量卷云中的后向散射及退偏比。测量表明:卷云最多出现高度接近9km,约50%的云都表明在某些高度存在一些近于水平取向的冰晶。围绕垂直方向的后向散射与角度的关系表明:这些冰晶对水平面的最大倾斜角约为0.3°。 | L.Thomas J.C.Cartwright D.P.Wareing 章育仲 | 1991 | 气象科技1991，19，3： | 0 |
| 7 | 脾血管浸润是胰体尾癌切除术后的不良预后因素显示文摘背景:由于较高的远处转移率,胰体尾癌是致死率最高的肿瘤之一。本研究旨在评估脾血管浸润对于胰体尾癌切除术患者的预后价值。方法:在这项回顾性研究中,我们收集了454例胰体尾癌患者的临床病理资料,通过单因素和多因素分析明确本组患者无进展生存(PFS)和总体生存(OS)的预后影响因素,重点关注脾动/静脉浸润的预后价值。结果:单因素分析结果显示,肿瘤较大、非导管内乳头状黏液瘤(non-IPMN)相关的腺癌、低分化、pT3期、淋巴结转移、脉管浸润、神经浸润、病理学脾静脉浸润、影像学脾静脉浸润者PFS和OS均显著缩短(均P<0.05)。多因素分析证实,non-IPMN相关腺瘤、pT3期、pN1-2期及术后辅助化疗是PFS和OS的独立危险因素;此外,肿瘤较大和影像学脾静脉浸润同时也是PFS的独立预后因素。结论:应当就如何检测和报告胰体尾癌手术标本的脾血管状态,形成一个统一的规范。 | Feng Yin Mohammed Saad Jingmei Lin Christopher R.Jackson Bing Ren Cynthia Lawson Dipti M.Karamchandani Belen Quereda Bernabeu Wei Jiang Teena Dhir Richard Zheng Christopher W.Schultz Dongwei Zhang Courtney L.Thomas Xuchen Zhang Jinping Lai Michael Schild Xuefeng Zhang Hao Xie Xiuli Liu | 2021 | Gastroenterology Report2021，9，2： | 0 |
| 8 | Effect of particle size distribution on particle based composite anode models显示文摘Particle based models of composite anodes are useful tools for exploring the behavior of SOFC systems. As part of our efforts to develop models for understanding fuel cells, we have been building models of Ni-YSZ composite anodes using experimentally measured particle size distributions. The objectives of this study were to characterize the percolation threshold and conductivity of these models in comparison to simpler mono dispersed and biphasic particle size distributions from the literature. We found that the average values for the onset of percolation and the measured conductivity of the models with experimentally measured particle size distributions are similar to those for the simple distributions and the experimentally measured distributions. For all of the configurations evaluated, the onset of percolation in the Nickel phase occurred at a solid fraction of Nickel between 20% and 25%. This corresponded almost exactly to the point at which the coordination number between Nickel phase particles reached 2.2. The significant finding was that the variation in the value for the conductivity, as measured by the standard deviation of the results, was several orders of magnitude higher than for the simpler systems. We explored the validity of our assumptions, specifically the assumption of random particle placement, by building a particle model directly from FIB-SEM data. In this reconstruction, it was clear that the location of particles was not random. Particles of the same type and size had much likelihood of contact higher than would indicated by random location. | Vaughan L.Thomas | 2013 | Acta Mechanica Sinica2013，29，3： | 0 |
