In this paper we introduce the hypothetical simulation model (HSM) of physical support. The HSM predicts that people judge physical support by mentally simulating what would happen if the object of interest were removed. Two experiments test the model by asking participants to evaluate the extent to which one brick in a tower is responsible for the rest of the bricks staying on a table. The res...

This paper describes the development of an approximate physical model that can be used for generating diierent types of protein crystallization behaviors or responses in varying physico-chemical environments. The modeling process involves three stages, two of which have been completed. The model developed in Stage I was over-simpliied and was aimed at providing the right computational avor of t...

Schizophrenia is a disorder with a large number of clinical, neurobiological, and cognitive manifestations, none of which is invariably present. However it appears to be a single nosological entity. This article considers the likely characteristics of a pathology capable of such diverse consequences. It is argued that both deficit and psychotic symptoms can be manifestations of a single patholo...

The present article includes the Ultrasound-Assisted Extraction (UAE) of Citrus unsiu Marc. leaves rich in polyphenols. The best possible combinations of solvent, pH of the media, solvent/solid ratio, extraction time, extraction temperature and particle size were obtained for the maximum extraction of Total Phenolic Compounds (TPC) and Total Flavonoid Compounds (TFC) by us...

This paper addresses a limitationof most deductive database systems: they cannot reason hypothetically. Although they reason eeectively about the world as it is, they are poor at tasks such as planning and design, where one must explore the consequences of hypothetical actions and possibilities. To address this limitation, we have developed a logic-programming language in which users can create...

We present a novel method for interleaving planning with execution, called iterative deepening in hypotheticals. The method consists of performing an iterative deepening search in the space of partially ordered hypothetical plans. Hypothetical plans are partial plans in which the achievement of an otherwise unachievable goal may be conditioned on certain outcomes of sensing. This approach has b...

The purpose of this study is to determine the influence on four premolar extractions for upper and lower anterior tooth size discrepancy (for total Bolton index (TBI=Overall ratio) and for Bolton value (BV)) and to find out the differences of four first and second premolar extractions tooth size discrepancies (TSD). 148 pretreatment dental casts have been examined. It has been determined that u...
