The Journal of Biomedical Research 2013年第5期27卷 372-379页

作者： Ankit Mahajan Swarkar Sharma Manoj k.Dhar Rameshwar N.k.Bamezai School of Biotechnology University of Jammu National Centre of Applied Human Genetics School of Life Sciences Jawaharlal Nehru University School of Biology and Chemistry Shri Mata Vaishno Devi University

We sought to identify risk factors for type 2 diabetes （T2D） in Jammu and kashmir populations, India. A total of 424 diabetic and 226 non-diabetic subjects from Jammu, and 161 diabetic and 100 non-diabetic subjects from kashmir were screened for various parameters including fasting blood glucose level, 2 hour glucose level, urea, creatinine, triglycerides, total cholesterol, high-density lipoprotein cholesterol （HDL-C）, low-density lipoprotein cholesterol （LDL-C）, very low-density lipoprotein （VLDL-C）, uric acid, systolic and diastolic blood pressure lev- el. We found that subjects aged 40-49 years had the highest rate of diabetes, with family income playing not much of a role. kashmiri migrants or populations with rapid cultural, environmental, social or lifestyle change along with reduced physical activity, obesity and unhealthy lifestyle （smoking and alcohol consumption） were found to have higher rates of diabetes. High blood glucose, triglycerides and low HDL-C levels were found to be con- tributing to disease outcome. High blood pressure also contributed to a higher risk of developing T2D. Our study supports earlier reports confirming the contribution of comfortable life style, Western dietary habits and rapid life style change along with many other factors to the prevalence of diabetes. This may contribute to the epidemic proportion of diabetes in Jammu and kashmir. Early diagnosis and routine screening for undiagnosed diabetes in obese subjects and subjects with parental diabetes history is expected to decrease the burden of chronic diabetic complications worldwide.

Photonic Sensors 2016年第2期6卷 181-186页

作者： Rajneesh k. VERMA Akhilesh k. MISHRA Department of Physics Central University of Rajasthan (India) BandarSindri Ajmer 305817 India Department of Electrical Engineering Technion - Israel Institute of Technology Haifa 32000 Israel

In the present study, we have theoretically modelled a surface plasmon resonance （SPR） based sensing chip utilizing a prism made up of gallium phosphidee. It has been found in the study that a large range of refractive index starting from the gaseous medium to highly concentrated liquids can be sensed by using a single chip in the visible region of the spectrum. The variation of the sensitivity as well as detection accuracy with sensing region refractive index has been analyzed in detail. The large value of the sensitivity along with the large dynamic range is the advantageous feature of the present sensing probe.

旨在提出一种运动学冗余空间机器人抓捕自旋卫星后的消旋策略和协调控制方法。首先,给出运动学冗余空间机器人捕获目标后的动力学模型,作为协调控制器设计基础。然后,基于四阶Bézier曲线和满足特定约束的自适应微分进化(Differential Evolution,DE)算法提出抓捕后的最优消旋与路径规划策略,最优消旋策略中同时考虑对消旋时间和控制力矩进行优化。提出一种跟踪所设计参考轨迹的协调控制方法,调整基座的姿态达到期望值。所提方法有效地衰减了自旋卫星的初始角速度,同时实现对基座姿态的控制。文末给出利用7 DOF冗余空间机械臂消除目标自旋运动的仿真结果,表明所提方法的有效性。
