Background: More than 20% of deaths from traffic crashes are related to pedestrians. This figure in Tehran, the capital of Iran, reaches to 40%. This study aimed to determine the high-risk areas and spatially analyze the traffic crashes, causing death to pedestrians in Tehran.   Methods: Mapping was used to display the distribution of the crashes. Determining the distribution pattern of...

Languages such as High Performance Fortran implement parallel algorithms by distributing large data structures across a multicomputer system. To enhance parallelism and reduce communication, it is sometimes bene cial for a programmer to change the distribution between phases of the algorithm. We introduce a new mapping strategy, called the spiral mapping, that reduces the communication overhead...

Background Cardiovascular magnetic resonance (CMR) T1 mapping has recently been shown to be highly sensitive for detecting myocardial iron overload. Furthermore, T1-mapping can be used to quantify relative concentrations of contrast agents that shorten T1. We hypothesized that T1 mapping can detect and quantify the myocardial distribution of a clinically available intravenous iron substitution ...

Objective(s): Multifunctional nanomedicine is the new generation of medicine, which is remarkably promising and associated with the minimum toxicity of targeted therapy. Distribution and transport of nanoparticles (NPs) in the blood flow are essential to the evaluation of delivery efficacy. Materials and Methods: In the present study, we initially designed a phantom based on Murray’s mini...

In this paper we consider a cutting process for random mappings. Specifically, for 0 < m < n, we consider the initial (uniform) random mapping digraph Gn on n labelled vertices, and we delete (if possible), uniformly and at random, m non-cyclic directed edges from Gn. The maximal random digraph consisting of the uni-cyclic components obtained after cutting the m edges is called the trimmed rand...

This paper presents an extension to a measurement system to capture bidirectional refEectance distribution function (BRDF) values and texture maps out of images. The extension will enable the measurement of reflection effects due to surface roughness and additionally extracts a map representing local surface displacements. Different lighting conditions where used to discriminate between surface...

Background & Aims: Despite improvements in public health in Iran, cutaneous leishmaniasis has become a growing health issue. About 90% of cutaneous leishmaniasis cases occur in 8 countries including Iran. Kala-azar or visceral leishmaniasis, as an important parasitic disease, is endemic in some areas of Iran. Mapping the distribution of parasitic diseases and determining their relations to geog...

Background and Aim: Brain mapping is a study of the anatomy and function of the CNS (central nervous system). Brain mapping has many techniques and these techniques are permanently changing and updating. From the beginning, brain mapping was invasive and for brain mapping, electrical stimulation of the exposed brain was needed. However, nowadays brain mapping does not require electrical stimula...
