Introduction: Resection of malignant pelvic tumors has long been considered to be associated with higher postoperative mortality and morbidity than resection of malignant limb tumors. We compared the postoperative adverse events of pelvic tumor surgery and limb tumor surgery using a national inpatient database. Methods: We identified patients who underwent surgery for primary musculoskeletal ma...

In an empirical two-sector model, it is investigated if permanent shocks originating from one sector have an effect on production in the other sector. The VAR contains three variables: employment in the private sector, and value added in industry and in the rest of the private sector. I found that shocks originating from one sector have no effect on production in the other sector, neither in th...

Stock assessment of Otolithes ruber was carried out using Virtual Population Analysis (VPA) method in the coastal waters of Northwest Persian Gulf. Catch and length frequency data during 2002-2012 were converted to age frequency. The maximum of stock number and biomass were observed in age group 1 and 2 respectively. The minimum of stock number and biomass were observed age group 6. The maximum...

A distribution free approach to the estimation of GARCH(1, 1) models is presented. More specifically, the proposed method relies on a Minimum Distance Estimator (MDE) based on the autocovariance function of the squared observations. The asymptotic properties of the estimator are studied giving conditions for its consistency and asymptotic normality while its finite sample efficiency is assessed...
