OBJECTIVE Researchers have advocated replacing the DSM-IV classification of personality disorders with an alternative diagnostic system based on the five-factor model. This study evaluates the clinical comprehensiveness of the five-factor model and addresses the broader question of how many factors, and which factors, are necessary to understand personality pathology. METHOD A national sample...

During binocular rivalry, perception alternates between two different images presented one to each eye. At any moment, one image is visible, dominant, while the other is invisible, suppressed. Alternations in perception during rivalry could involve competition between eyes, eye-rivalry, or between images, image-rivalry, or both. We measured response criteria, sensitivities, and thresholds to br...

When equity default swap (EDS) contracts were first included in a rated collateralized debt obligation (CDO) deal, some critics doubted the originality of the product. In fact, EDSs are equivalent to already existing binary barrier options on equity, except the premium is not paid upfront, but over time, and conditional on the trigger event not having occurred. Therefore, as opposed to existing...

We study specific nonlinear transformations of the Black-Scholes implied volatility to show remarkable properties of the volatility surface. Model-free bounds on the implied volatility skew are given. Pricing formulas for the European options which are written in terms of the implied volatility are given. In particular, we prove elegant formulas for the fair strikes of the variance swap and the...

Most successful heuristics for solving 1||wjTj are based on swap moves. We present an algorithm which improves the complexity of searching the swap neighborhood from O(n3) to O(n2). We show that this result also improves the complexity of the dynasearch heuristics by Congram et al. [1] and Grosso et al. [3].

irrigation scheduling means applying the right amount of water at the right time. in this research, thecurrent irrigation scheduling implemented in the mirza-kuchak-khan sugarcane agro-industry farmslocated in ahwaz was compared with the actual sugarcane crop water requirement using swapmodel. due to lack of field measured data, the swap model was calibrated and evaluated usinglandsat 7 etm+ im...
