Nowadays, data handled by an institution or company is spread out by more than one database and lots of documents of different types. To extract the information implicit in that data, it is necessary to pick parts from those various archives. To obtain a general overview, those information slices should be gather. Different approaches can be followed to achieve that integration, ranging from th...

The most general evolution of the density matrix of a quantum system with a finite-dimensional state space is by stochastic maps which take a density matrix linearly into the set of density matrices. These dynamical stochastic maps form a linear convex set that may be viewed as supermatrices. The property of hermiticity of density matrices renders an associated supermatrix hermitian and hence d...

background: accidents are the second reason for mortality and morbidity in iran. among them, brain injuries are the most important damage. clarification of the effects of brain injuries on different body systems will help physicians to prioritize their treatment strategies. in this study, the effect of pure brain trauma on the cardiovascular system and lungs 24 hours post trauma was assessed. m...

This study is an attempt to gain insight into the malleability of representational maps in the primary somatosensory cortex in relation to the expression of proteins involved in inhibitory and excitatory neurotransmitter systems that contribute to maintain these maps in a dynamic state. Malleability of somatosensory maps is characterized by changes in the sizes of neuron receptive fields (RFs) ...

This paper describes the digitization and utilization of Complete Map of Peking, Qianlong Period, which is the oldest measured map of Beijing made about 250 years ago. We first proposed the geometric correction method called “linepreserving distance weighting method” to preserve linear features relevant in the old map of cities. Next we improved the reliability of the old map as information inf...

In E-Learning, the selection of the pedagogical contents to teach and the organization of this content are two principal operations during the design of a course. The growth and the diversity of the informational resources used generate problems of diffusion, access, of classification and management. With the MEMORAe project, we deal with these problems and propose to answer them by using an on...

This paper explores the idea of using contexts to support more efficient information search in Topic Maps-based digital libraries. The notion of context is perceived as abstraction of grouping of domain concepts and resources based on the existing semantic relationships between them. The proposed model of context is used for context representation in the TM4L environment.

Demands to make education flexible and active call for a comprehensive restructuring of the traditional university course format. We show how such restructuring can be done in a natural and coherent way by combining e-learning with Polyscopic Topic Maps, an information structuring method which is being developed by the authors. We describe a university course model called Flexplearn which is ba...

background: there is much debate about effects of medicinal plants such as saffron (crocus sativus) on human health. women are highly involved in farming and processing of this plant. this study is aimed at evaluating the saffron impacts on miscarriage rate of female farmers working in saffron fields. methods: this was a prospective case-control study on pregnant female farmers during harvestin...
