the purpose of this study is finding the sensitivity of central bank independence measurements on its impact on inflation in iran. to this aim different measurements of the central bank independence were calculated using the indices of grilli et al. (1991), cukierman et al. (1992), mathew (2006) and dumiter (2009) for the period 1961-2012 . although results of correlation between cbi index and ...

BACKGROUND The health, economic and societal burden of asthma is considerable, and is greatest in patients with severe asthma, particularly when inadequately controlled. Real-life studies that assess the effectiveness of treatment are of particular interest. METHODS We determined the incremental cost-effectiveness ratio (ICER) of adding omalizumab to standard therapy using data from the real-...

In clinical decision making, it is common to ask whether, and how much, a diagnostic procedure is contributing to subsequent treatment decisions. Statistically, quantification of the value of the information provided by a diagnostic procedure can be carried out using decision trees with multiple decision points, representing both the diagnostic test and the subsequent treatments that may depend...

We provide a probabilistic analysis of the output of Quicksort when comparisons can err.

Infinite groups have been used for cryptography since about twenty years ago. However, it has not been so fruitful as using finite groups. An important reason seems the lack of research on building a solid mathematical foundation for the use of infinite groups in cryptography. As a first step for this line of research, this paper pays attention to a property, the so-called right-invariance, whi...

the behavior of earth dams has particular complexities against dynamic forces and its assessment requiresdetailed and scientific analysis. the farrokhi earth dam is a heterogeneous type with vertical clay core, built 150 km away from birjand and 41 km away from qaen on the farrokhi river. there are concernsregarding the stability of this dam in the event of a future severe earthquake especially...

A discrete model, inspired by publication activity, is introduced. It includes an increasing number of objects equipped with positive weights, which also increase with time. The random evolution of the model is driven by a weight dependent dynamics in such a way that the empirical weight distribution converges weakly with probability 1, and the limit law has a regularly varying tail. The probab...

In the planning and design of new clinical trials, calculation of the required sample size and power is a critical part of the process. Power calculations are usually based on quantities estimated from analysis of historical data and are therefore subject to uncertainty. In many cases this is addressed by sensitivity analysis, but simple sensitivity analysis gives an incomplete picture of the u...
