A risk model of a joint business (insurer/re-insurer) is studied in the Large Deviations (LD) regime. In the model considered, the premium paid by the insurer to the re-insurer changes if the insurer’s capital falls below a certain level P . An optimal premium arrangement for the both business participants is investigated. By a proper choice of parameters involved, it is possible to increase th...

The premise of this work was to understand the role ‘cost’ or total cost of ownership of software plays in government procurement decisions. We found, however, that this was more a rhetoric to gain acceptance for ope...

The management of this problem considerably increases the length and the cost of hospitalization.  The aim of this study is to analyze the incidence, predisposing factors, and outcome of PCF in patients undergoing total...
