The Kumaraswamy distribution is a two-parameter distribution on the interval (0,1) that is very similar to beta distribution. This distribution is applicable to many natural phenomena whose outcomes have lower and upper bounds, such as the proportion of people from society who consume certain products in a given interval. In this paper, we introduce the family of Kumaraswamy-G distribution, an...
Associations of C-reactive protein (CRP) and fibrinogen with death may weaken over time. Combining both markers may improve prediction of death in older adults. In 5,828 Cardiovascular Health Study participants (United States, 1989-2000), 383 deaths (183 cardiovascular disease (CVD)) in years 1-3 (early) and 914 deaths (396 CVD) in years 4-8 (late) occurred. For men, when comparing highest to l...
Cardiovascular diseases are associated with chronic activation of Rho-associated kinase. Rho-associated kinase activity is significantly correlated with endothelial function and Framingham risk score. However, there is no information on the prognostic value of Rho-associated kinase activity. We evaluated Rho-associated kinase activity in peripheral leukocytes by Western blot analysis in 633 sub...
Background and purpose: Mortality in HIV-positive patients is due to various reasons such as progression to AIDS or co-infection with AIDS and TB or other causes. In survival analysis, competing risk methods are used if there are different reasons for death. The purpose of this article was to identify the factors affecting various causes of death using competing risk methods. Materials and met...
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
Several characterizations of a New Modified Weibull distribution, introduced by Doostmoradi et al. (2014), are presented. These characterizations are based on: (i) truncated moment of a function of the random variable (ii) the hazard function (iii) a single function of the random variable (iv) truncated moment of certain function of the 1st order statistic.
OBJECTIVE To evaluate the association of kidney function with cardiovascular disease and mortality among apparently healthy women. DESIGN Prospective cohort study. SETTING Women's Health Study, United States. PARTICIPANTS 27 939 female health professionals aged >or=45 who were free of cardiovascular disease and other major disease and who provided a blood sample at study entry. MAIN OUT...
A study was undertaken to determine the early and long-term outcomes dictated by the Fontan state per se (a state in which the force driving pulmonary blood flow is solely or largely a residue, in the systemic venous pressure, of the main ventricular chamber's contractile force) and the transition (by surgery) to it from the state of congenital heart disease under optimal conditions (after a "p...
BACKGROUND Left ventricular noncompaction is a cardiomyopathy characterized by excessive trabeculation of the left ventricle, progressive myocardial dysfunction, and early mortality. Left ventricular noncompaction has a heterogeneous clinical presentation that includes arrhythmia and sudden cardiac death. METHODS AND RESULTS We retrospectively reviewed all children diagnosed with left ventric...
Background and Aim: In many diagnostic studies, including surveying the survival of patients with gastric cancer where each individual after surgery can experience more than one type of event, and the occurrence of one type of event hinders the occurrence of other types of events, the question of competing risk is raised. For checking the effect of each covariate on the occurrence of any even...
