本文讨论如何处理好控制混合电动车辆的动力系,基于多目标优化推荐了一个功率分流混合电动车辆的优化工作。开发了一个准静态动力系模型,探索了整个工作选择的空间,以便找到一个可达到的最佳工作可选择的组合。采用这种概念,开发了二种模拟:模拟一是基于等量燃油消耗量最小,其二是采用动态优化。按结果的分析和比较,按最小的等量燃油消耗找出几乎最高的效率,作为按优化控制模拟求得理论上最大的性能。结果除了在高动力负荷工况外不表示显著的差异。根据这个分析,同时为车辆在纯电动车辆工作模式推荐了一个临界值。

Exercise-induced rhabdomyolysis mechanisms and prevention:A literature review

引用

Journal of Sport and Health Science 2016年第3期5卷 324-333页

作者： Jooyoung Kim Joohyung Lee Sojung Kim Ho Young Ryu Kwang suk cha Dong Jun Sung Health and Rehabilitation Major College of Physical Education Kookmin University Department of Physical Education Global Campus Kyung Hee University Department of Physical Therapy College of Health Science University of Massachusetts Division of Sport Science College of Science and Technology Konkuk University

Exercise-induced rhabdomyolysis(exRML), a pathophysiological condition of skeletal muscle cell damage that may cause acute renal failure and in some cases death. Increased Ca^(2+) level in cells along with functional degradation of cell signaling system and cell matrix have been suggested as the major pathological mechanisms associated with exRML. The onset of exRML may be exhibited in athletes as well as in general population. Previous studies have reported that possible causes of exRML were associated with excessive eccentric contractions in high temperature, abnormal electrolytes balance, and nutritional deficiencies possible genetic defects. However, the underlying mechanisms of exRML have not been clearly established among health professionals or sports medicine personnel. Therefore, we reviewed the possible mechanisms and correlated prevention of exRML, while providing useful and practical information for the athlete and general exercising population.

Comparison of CT and MRI for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma

AIM:To determine the accuracy of computed tomography (CT) and magnetic resonance (MR) for presurgical characterization of paraaortic lymph nodes in patients with pancreatico-biliary carcinoma. METHODS:Two radiologists independently evaluated CT and MR imaging of 31 patients who had undergone lymphadenectomy (9 metastatic and 22 non-metastatic paraaortic nodes). Receiver operating characteristic (ROC) curve analysis was performed using a five point scale to compare CT with MRI. To re-define the morphologic features of metastatic nodes, we evaluated CT scans from 70 patients with 23 metastatic paraaortic nodes and 47 non-metastatic ones. The short axis diameter, ratio of the short to long axis, shape, and presence of necrosis were compared between metastatic and non-metastatic nodes by independent samples t-test and Fisher's exact test. P characterization of paraaortic nodes is not different from that of MRI. A short axis-diameter (> 5.3 mm), irregular margin, and presence of central necrosis are the suggestive morphologic features of metastatic paraaortic nodes.

Prediction of liver cirrhosis, using diagnostic imaging tools

引用

World Journal of Hepatology 2015年第17期7卷 2069-2079页

作者： suk Keu Yeom chang Hee Lee Sang Hoon cha Cheol Min Park Department of Radiology Korea University Ansan Hospital Korea University College of Medicine Department of Radiology Korea University Guro Hospital

Early diagnosis of liver cirrhosis is important. Ultrasoundguided liver biopsy is the gold standard for diagnosis of liver cirrhosis. However, its invasiveness and sampling bias limit the applicability of the method. Basic imaging for the diagnosis of liver cirrhosis has developed over the last few decades, enabling early detection of morphological changes of the liver by ultrasonography(US), computed tomography, and magnetic resonance imaging(MRI). They are also accurate diagnostic methods for advanced liver cirrhosis, for which early diagnosis is difficult. There are a number of ways to compensate for this difficulty, including texture analysis to more closely identify the homogeneity of hepatic parenchyma, elastography to measure the stiffness and elasticity of the liver, and perfusion studies to determine the blood flow volume, transit time, and velocity. Amongst these methods, elastography using US and MRI was found to be slightly easier, faster, and able to provide an accurate diagnosis. Early diagnosis of liver cirrhosis using MRI or US elastography is therefore a realistic alternative, but further research is still needed.

AIM： To compare the diagnostic accuracy of computed tomography （CT） and positron emission tomography （PET） for the preoperative detection of paraaortic lymph node （PAN） metastasis in patients with intra- abdominal malignancies. METHODS： Sixty-six patients with intra-abdominal malignancies who underwent both CT and PET before lymphadenectomy were included in this study. Histopathologicaliy, 13 patients had metastatic PAN, while 53 had non-metastatic PAN. The CT criteria for metastasis were： short diameter ：）f 〉 8 mm, Iobular or irregular shape, and/or combined ancillary findings, including necrosis, conglomeration, vessel encasement, and infiltration. The PET criterion was positive fluorodeoxyglucose （FDG） uptake. The sensitivity, specificity, positive predictive value （PPV）, negative predictive value （NPV）, and accuracy of both modalities were compared with the pathologic findings, and the false positive and false negative cases with both CT and PET were ***： The sensitivity, specificity, PPV, NPV, and accuracy of CT were 61.5%, 84.9%, 50%, 90% and 80.3%, respectively. For PET, the percentages were 46.2%, 100%, 100%, 88.3%, and 89.4%. Additionally, there were 8 false positive CT cases （8/53, 15.1%） and zero false positive PET cases. Of the 13 metastatic PANs, there were 5 false negative CT scans （38.5%） and 7 （53.9%） false negative PET ***： For detecting PAN metastasis, CT is more sensitive than PET, while PET is more specific.
