Received (to be inserted Revised by Publisher) We investigate the consequences of maximizing information transfer in a simple neural network, with bounded and invertible transfer functions. In the case of a vanishing additive output noise, and an even smaller input noise, the main result is that maximization of information (over receptive elds and transfer functions) leads to a factorial code-h...

How does learning to categorize objects affect how people visually perceive them? Behavioral, neurophysiological, and neuroimaging studies have tested the degree to which category learning influences object representations, with conflicting results. Some studies have found that objects become more visually discriminable along dimensions relevant to previously learned categories, while others ha...

the first experimental sam for iran was constructed more than three decades ago under the supervision of prof. pyatt. based on this work prof pyatt had observed that the way in which iran was spending oil revenues was likely to exacerbate urban—rural income differentials in iran. in his approach to sam he did not distinguish between factorial and institutional income distributions preferring to...

The Humor Styles Questionnaire (HSQ; Martin et al., 2003) is one of the most frequently used questionnaires in humor research and has been adapted to several languages. The HSQ measures four humor styles (affiliative, self-enhancing, aggressive, and self-defeating), which should be adaptive or potentially maladaptive to psychosocial well-being. The present study analyzes the internal consistenc...

Background: The transtheoretical model (TTM) is used as a framework to implement smoking cessation programs. This model has some subscales based on which the smoking temptation scale is proposed as stages movement factor. This study aimed to translate and validate the temptation subscales of the TTM questionnaire in the Iranian population. Methods...

In these notes we investigate the cone of nef curves of projective varieties, which is the dual cone to the cone of pseudo-effective divisors. We prove a structure theorem for the cone of nef curves of projective Q-factorial klt pairs of arbitrary dimension from the point of view of the Minimal Model Program. This is a generalization of Batyrev’s structure theorem for the cone of nef curves of ...
