several characterizations of marshall-olkin generalized distributions, introduced by gui (2013) and by al-saiari et al. (2014) are presented. these characterizations are based on: (i) a simple relationship between two truncated moments ; (ii) the hazard function.

FMEA has been used for several years and proved its efficiency for system’s risk analysis due to failures. Risk priority number found in FMEA is used to rank failure modes that may occur in a system. There are some guidelines in the literature to assign the values of FMEA components known as Severity, Occurrence and Detection. This paper propose a method to assign the value for occurrence in mo...

Impact from natural hazards is a shared global problem that causes tremendous loss of life and property, economic cost, and damage to the environment. Increasingly, many natural processes show evidence of nonstationary behavior including wind speeds, landslides, wildfires, precipitation, streamflow, sea levels, and earthquakes. Traditional probabilistic analysis of natural hazards based on peak...

BACKGROUND Patients with aortic stenosis (AS) often have concomitant hypertension. Antihypertensive treatment with a β-blocker (Bbl) is frequently avoided because of fear of depression of left ventricular function. However, it remains unclear whether antihypertensive treatment with a Bbl is associated with increased risk of cardiovascular events in patients with asymptomatic mild to moderate AS...

OBJECTIVES This study investigated the influence of baseline and worsening renal function (WRF) on the efficacy of spironolactone in patients with severe heart failure (HF). BACKGROUND Renal dysfunction or decline in renal function is a known predictor of adverse outcome in patients with HF, and treatment decisions are often on the basis of measures of renal function. METHODS We used data f...

AIMS Renal dysfunction is associated with poor cardiovascular outcome. We investigated the relationship of kidney function and long-term cardiovascular outcomes in patients with high risk myocardial infarction. METHODS AND RESULTS We studied 27 610 patients from four randomized trials of acute myocardial infarction complicated by heart failure and/or LV dysfunction (LVEF ≤40%). Two trials exc...

Temperature implies contrasting biological causes of demographic aging in poikilotherms. In this work, we used the reliability theory to describe the consistency of mortality with age in moth populations and to show that differentiation in hazard rates is related to extrinsic environmental causes such as temperature. Moreover, experiments that manipulate extrinsic mortality were used to disting...

INTRODUCTION Current risk assessment concepts in ST-elevation myocardial infarction (STEMI) are suboptimal for guiding clinical management. AIM To elaborate a composite risk management concept for STEMI, enhancing clinical decision making. MATERIAL AND METHODS 1995 unselected, registry patients with STEMI treated with primary percutaneous coronary intervention (pPCI) (mean age 60.1 years, 7...
