In this paper, we discuss dierent predictors of times to failure of units censored in multiple stages in a progressively censored  sample from proportional hazard rate models. The maximum likelihood predictors, best unbiased predictors and conditional median predictors are considered. We also consider Bayesian point predictors for the times to failure of units. A numerical example and a Monte C...

conclusions cmm in yazd is a low-incidence skin tumor that shows a relatively fixed incidence between 1988 and 2008, higher incidences of cmm were found in sun-exposed areas (especially head and neck areas), with more incidence in men. skin cancers and cmm incidence in iran is lower than western countries, most probably due to geographical zone, genetic factors, skin type, society-related custo...

the effects of four corn hybrids, keynes540, keynes410, ksc260 and ksc400, were investigated on life table parameters of the beet armyworm in a growth chamber that was set at 25 ± 1 ºc, 65 ± 5% rh and 16:8 (l: d) photoperiod. the highest survivorship (lx) of adults were 0.77, 0.70, 0.62 and 0.58 on ksc260, keynes410, keynes540 and ksc400, respectively. the highest age-specific fecundity (mx) of...

conclusions the survival rate after in-hospital cpr was very low. the duration of cpr and the time of initiating cpr effects patients’ outcomes. these findings highlight the crucial role of an organized, skilled, well-established and timely cpr team. background despite several studies, there is no agreement on factors that affect survival after in-hospital cardiopulmonary resuscitation (cpr). o...

background: esophageal cancer is one of the prevalent cancers in east azerbaijan province. the aims of this study are to estimate the survival rate of patients with esophageal cancer by treatment modalities and tumor location, as well as risk factors such as cigarette smoking, family history, age at diagnosis, and gender. materials and methods: in a cross-sectional study we evaluated 142 patien...

the main vector of malaria in europe and palearctic region is anopheles maculipennis complex. in order to determine the survival rate of an. maculipennis s.l. this study was carried out in garaboteh (zanjan province, iran) in july 2003. in this study anophelines were sampled for 31 consecutive days from five fixed animal shelters and five light traps. out of 24481 collected an. maculipennis s.l...

A recurrent question within oncology drug development is predicting phase III outcome for a new treatment using early clinical data. One approach to tackle this problem has been to derive metrics from mathematical models that describe tumour size dynamics termed re-growth rate and time to tumour re-growth. They have shown to be strong predictors of overall survival in numerous studies but there...

predation rate is basic to any investigation of prey-predator interaction and a major component in the selection of predators for biological control. the predation rate of variegated lady beetle, hippodamia variegata (goze), fed on different densities (20, 40, 60, 80 and 100) of third instar nymphs of cotton aphid, aphis gossypii glover, was studied under laboratory conditions (25 ± 1 °c, 65 ± ...
