The first quantitative neural network model of feelings and emotions is proposed on the base of available data on their neuroscience and evolutionary biology nature, and on a neural network human memory model which admits distinct description of conscious and unconscious mental processes in a time dependent manner. As an example, proposed model is applied to quantitative description of the feel...

This article provides an overview of natural phonological processes in the dialect of Sistani Persian spoken in Iranian Sistan, and reviews theoretical implications of these processes. A representative selection of processes in the language is examined in reference to conditioning by surrounding segments and conditioning in reference to syllable structure. While assimilation and dissimilation a...

Fractals have experienced considerable success in quantifying the complex structure exhibited by many natural patterns and have captured the imagination of scientists and artists alike [Mandelbrot]. With ever widening appeal, they have been referred to both as "fingerprints of nature" [Taylor et al 1999] and "the new aesthetics" [Richards]. Recently, we showed that the drip patterns of the Amer...

An intelligent agent uses known facts including statistical knowledge to assign degrees of belief to assertions it is un certain about We investigate three principled techniques for doing this All three are applications of the principle of indi erence because they assign equal degree of belief to all basic situations consistent with the knowledge base They di er because there are competing intu...

Most approaches to generative phonology grant a privileged status to “natural” phonological rules, those that have a clear phonetic motivation. In Optimality Theory, for example, children are typically assumed to begin language learning with markedness constraints ranked above faithfulness constraints (see Smolensky 1996). The implication — often not made explicit — is that phonetically arbitra...

The paper is concerned with supporting natural patterns of scientific collaboration in Access Grid environments. We reveal that no current approach to Access Grid allows dynamic session invocation within on-going Access Grid sessions nor workflow driven session triggering among users involved in that workflow. A model for a lightweight signaling architecture integrated within Access Grid is pro...

In this paper, crystallographic aspects of ancient, medieval and modern Turkish ornaments are dealt with. Crystallographic patterns (CPs) are considerably different from other patterns. The following are characteristic of CPs: the edge of ornament elements draws the edge of the figure; maximal compactness of the ornament elements; lack of background or transformation of background to ornament e...

Under the current scenario of rapid human population increase, achieving efficient and productive agricultural land use while conserving biodiversity is a global challenge. There is an ongoing debate whether land for nature and for production should be segregated (land sparing) or integrated on the same land (land sharing, wildlife-friendly farming). While recent studies argue for agricultural ...

Generalist predators such as spiders and ground beetles provide important ecosystem services by suppressing density of pest insects in agroecosystems, which offers a sustainable solution to trade-off between agricultural production and biodiversity conservation. There is increasing recognition that landscape factors beyond field-plot scale are important determinants for community structure of g...
