time-dependent schrödinger equation for a 1-d model of hydrogen molecular ion h2+ in intenselaser field linearly polarized along the molecular axis is solved. ionization rates are calculated for differentinitial states. the evolution of electronic wavefunction at fixed inter-nuclear separations are simulated andanalyzed. the results obtained for the ground state of this 1-d model of h2+ show ap...

Organic Computing (OC) has become a challenging vision for the design of future information processing systems: As they become increasingly powerful, cheaper and smaller, our environment will be lled with collections of autonomous systems equipped with sensors and actuators to be aware of their environment, to communicate, and to organize themselves in order to perform the actions and servic-es...

Autonomous motion planning addresses the problem of nding collision-free paths for moving objects robots among obstacles. In this report we consider robots operating in workspaces occupied by stationary, completely known obstacles. We describe a new approach to probabilistic roadmap planners (PRMs). The overall theme of the algorithm, called Lazy PRM, is to minimise the number of collision chec...

Invariant Pictorial Recognition Zhiqian Wang and Jezekiel Ben-Arie EECS Department, University of Illinois at Chicago, Chicago, IL 60607 Abstract This paper presents an e cient scheme for a neinvariant object recognition. A ne invariance is obtained by a representation which is based on a new sampling con guration in the frequency domain. We discuss the decomposition of a ne transform into slan...

Introduction: Nuclear moisture density gauges are widely used in construction industry in different countries across the world, including Ghana, on a large scale. Like all irradiating devices, the nuclear gauges should be subjected to radiation safety assessment based on radiation protection and safety principles. Regarding this, the objective of this research was to i...

Introduction: The aim of present study was to estimate effective dose from most common procedures performed in nuclear medicine departments of Golestan province. Methods: Data of nuclear medicine procedures performed in 2 nuclear medicine departments in Golestan province were collected during 4 years. Effective dose, collective effective dose and effective dose per examination were calculated ...

Introduction: Ionizing radiation in medical imaging is one of the dominant sources of exposure, and correct knowledge of radiation protection, affects staff safety behaviors during procedures. This study aimed to assess the radiation protection Knowledge, Attitude and Practice (KAP) amongst nuclear medicine centers' staff in Iran. Methods: To evaluate the...

Background: Androgen receptor (AR) plays a critical role in prostate cancer and male sexual differentiation.Mechanisms by which AR acts and regulations of AR nucleocytoplasmic shuttling are not understood well. Materials and Methods: Degenerate PCR and RACE Cloning of AR Gene; Phylogenetic Analysis and Molecular Modeling;Real-time Fluorescent Quantitative RT-PCR; Northern Blot Hybridization;In ...
