Philosophers, physicists, and cognitive psychologists, as well as many other scientists in their areas of research, have been dealing with the question of how the world is constructed or in a human-centered view its structure is perceived by us. This central question and related ones have occupied thinkers for thousands of years, going back at least to Aristotle. In the meantime, descriptions o...

Today Congratulations today to Camilla Schwind for the acceptance of her article \Causality in Action Theories" for publication in the ETAI. Both referees recommended acceptance; one of them suggested minor changes to the article. The relationship between Actions and Change research on one hand, and Planning and Scheduling research on the other may be much closer in the future than it has been ...

Developing simple, sensitive and selective sensing systems for dopamine is important due to its biological significance. In this work, a silver nanoparticles-modified carbon paste electrode (AgNPs-CPE) has been constructed and used to detect of dopamine (DA) in the simultaneous presence of ascorbic acid (AA) and uric acid (UA) at neutral pH 7.0 by cyclic voltammetry. The modified electrode show...

We focus on learning representations of dynamical systems that can be characterized by logic-based formalisms for reasoning about actions and change, where system’s behaviors are naturally viewed as appropriate logical consequences of the domain’s description. To this end, logic-based induction methods are adapted to identify the input/output behavior of a dynamical system corresponding to an e...

In 2] C. Baral and M. Gelfond present the language A C for representing concurrent actions in dynamic systems, and give a sound but incomplete encoding of this language in terms of extended logic programming. Using their program, the time the computation of the transition from one situation to another takes increases quadraticly with the size of the considered domain. In this paper, we present ...

In the fields of psychiatry and neurology, the dopaminergic system is one of the most important neurotransmitter systems in the brain. Whereas pharmacological and biochemical studies had initially indicated two subclasses of dopamine receptors (DA-R), recent progress in molecular biology techniques has led to the identification of five distinct genes of DA-Rs (D1-R-D5-R) and splice variants. Th...
