as the organizational relationships are effective in geographic environment of human settlements for development quality and its infrastructures, also it is influenced from space- place trends and development approaches definition and set to dialogue, not a different definition and set differently and they are effective in their spatial extent . on this basis, in this paper is trying to help so...

the present study aimed to investigate the generic organization of research article introductions in local iranian and international journals in english for specific purposes, english for general purposes, and discourse analysis. overall, 120 published articles were selected from the established journals representing the above subdisciplines. each subdiscipline was represented by 20 local and 2...

A discrete alternative to scale space filtering is presented. The new method provides for fast solutions to problems of spatial containment, filtering and matching, without using arbitrary parameters and smoothing of the input. The discrete space-scale representation is a hierarchical perceptual organization that has concrete applications in computer vision research. Examples of actual implemen...

In search for global principles that may explain the organization of the space of all possible proteins, we study all known protein sequences and structures. In this paper we present a global map of the protein space based on our analysis. Our protein space contains all protein sequences in a non-redundant (NR) database, which includes all major sequence databases. Using the PSI-BLAST procedure...

stimuli. We found that the space-time slant of the receptive field of directional simple cells differed for high and low contrast stimuli, with the space-time slant predicting higher optimum speeds for the higher contrast stimuli; i.e. there was a larger spatial shift of the receptive-field organization per unit time. Not only did the space-time maps of directional simple cells show different s...

The e€ects of mesoscale circulations induced by soil moisture heterogeneities are studied to assess the impact that the coupling of the land surface and the planetary boundary layer has on the rainfall and soil moisture dynamics at di€erent scales. Our goal is to single out the most important physical mechanisms which a€ect the behaviour of the land-atmosphere system at the mesoscale leading to...

In this paper, we develop a spatio-temporal memory that blends properties from long and short-term memory and is motivated by reaction diffusion mechanisms. The winning processing element of a self-organizing network creates traveling waves on the output space that gradually attenuate over time and space to diffuse temporal information and create localized spatio-temporal neighborhoods for clus...

Wheat and maize genes were hypothesized to be clustered into islands but the hypothesis was not statistically tested. The hypothesis is statistically tested here in four grass species differing in genome size, Brachypodium distachyon, Oryza sativa, Sorghum bicolor, and Aegilops tauschii. Density functions obtained under a model where gene locations follow a homogeneous Poisson process and thus ...
