this article examines statistical inference for  where and are independent but not identically distributed pareto of the first kind (pareto (i)) random variables with same scale parameter but different shape parameters. the maximum likelihood, uniformly minimum variance unbiased and bayes estimators with gamma prior are used for this purpose. simulation studies which compare the estimators are ...

Inverse sampling design is generally considered to be appropriate technique when the population is divided into two subpopulations, one of which contains only few units. In this paper, we derive the Horvitz-Thompson estimator for the population mean under inverse sampling designs, where subpopulation sizes are known. We then introduce an alternative unbiased estimator, corresponding to post-st...

The objective of this study was to evaluate the therapeutic safety and efficacy of percutaneous radiofrequency ablation (RFA) with Internally Cooled Electrode for malignant hepatic tumors; which were in contact with blood vessels. A total of 297 patients with malignant hepatic tumors (358 nodules) who underwent RFA, by means of straight Internally Cooled Electrodes, were enrolled in this study....

To provide health services to its population of 1.2 billion, China has 200 000 health establishments including 62 000 public hospitals (Ministry of Health 1996). China has some 3 million hospital beds in operation, averaging 2.4 beds per thousand people. This is a higher per capita ratio than is found in other low-income regions of the world. Three-quarters of China’s total health spending goes...

The systemic pharmacological treatment of disease is limited by severe toxicity to normal organs/tissue. Therefore, various delivery vehicles have been designed to carry therapeutic drugs to their target tissues. We designed a novel vehicle formed by the interaction of biotins in a DNA (polymer) with avidins (crosslink), resulting in a porous particle. This self-assembled (HSAM) nanoparticle ve...
