F unctional magnetic resonance imaging (fMRI) is a noninvasive, powerful tool that has been utilized in both research and clinical arenas since the early 1990s [1] and has provided valuable insights to the understanding of the human brain function. fMRI has enabled researchers to directly study the temporal and spatial changes in the brain as a function of various stimuli. Because it relies on ...

background and objectives: stress among students of the health sciences can lead to reduced performance of future healthcare human resources. to address this threat there is a need to develop a robust understanding of the nature and intensity of stress in these professionals. to help approaching this goal, the present study assessed stress-induced life change in students of tehran university of...

Suppose that an international group of scientists presents a 15-year, €750 million research programme to unravel the molecular mechanisms of metabolic syndrome, a disorder implicated in obesity, type 2 diabetes, cardiovascular diseases, cancer and other diseases. The results from this project will neither replace obvious preventive measures—such as reducing food intake or increasing exercise—no...

Clustering is the task of organizing a set of objects into meaningful groups. These groups can be disjoint, overlapping, or organized in some hierarchical fashion. The key element of clustering is the notion that the discovered groups are meaningful. This definition is intentionally vague, as what constitutes meaningful is to a large extent, application dependent. In some applications this may ...

In the context of these financing difficulties it does not seem too likely that larger-thanneeded commercially available units will be purchased and operated at low capacity as an alternative to small units. This approach can be economical over the long term and is an immediate way to purchase a commercially available reactor. It does not seem likely, however, since it would exacerbate the prob...

Even the simplest known biological organisms have thousands of genes and millions of DNA base pairs. This makes it necessary to study the distribution and dynamics of genetic variation at many loci (or genetic markers) simultaneously. A particular combination of genes (or genetic markers) for a DNA segment under consideration is referred to as haplotype. In what follows different haplotypes wil...
