In this paper, we will use a quantum operator which performs the inversion about the mean operation only on a subspace of the system (Partial Diffusion Operator) to propose a quantum search algorithm runs in O( √ N/M ) for searching unstructured list of size N with M matches such that, 1 ≤ M ≤ N . We will show that the performance of the algorithm is more(More)
In this paper we critically survey the AI programs that have been developed to exhibit some aspect of creative behaviour. We describe five necessary characteristics of models of creativity, and we apply these characteristics to help assess the programs surveyed. These characteristic features also provide a basis for a new theory of creative behavior: an(More)
The bacterium Escherichia coli has the capacity to respond to a wide range of environmental inputs, which have the potential to change suddenly and rapidly. Although the functions of many of its signal transduction and gene regulation networks have been identified, E.Coli’s capacity for perceptual categorization, especially for discrimination between(More)
The smooth muscle of the in vitro guinea-pig vas deferens was shown to contract upon addition of adenosine triphosphate (ATP), adenosine diphosphate (ADP), and adenosine monophosphate (AMP), the order of potency being ATP greater than ADP greater than AMP. Adenosine did not produce contraction. Pretreatment of animals with reserpine or treatment of tissues(More)

Reliable assessments of the relative contributions of diet (food, beverages, and orally administered drugs) and air (inhaled fibers) to total ingested asbestos exposure are not feasible due to the paucity of quantitative data on the subject. Instead, scenarios for both modes of exposure were developed from the limited information available to give crude(More)
Using the most comprehensive inhalation study available, (Wagner, et al., 1974), the dose-response effects of the four major types of asbestos fibers (amosite, anthophyllite, crocidolite, and chrysotile: Canadian, Rhodesian) for lung cancer have been determined. From linear regression analysis of the animal data and five human epidemiology studies giving a(More)
Using a simple simulation model of evolution and learning, this paper provides an evolutionary argument why Lamarckian inheritance the direct transfer of lifetime learning from parent to offspring may be so rare in nature. Lamarckian inheritance allows quicker genetic adaptation to new environmental conditions than non-lamarckian inheritance. While this may(More)
