Multiparametric segmentation techniques, which require integration of 2 or more MRI sequences, are the newest method.13 In one study,56 for example, proton-density and T2-weighted sequences and T1- and T2-weighted images were combined and used to calculate lesion area.47 These approaches provide...
In fact, SE is the standard deviation of the fitted parameter obtained from the nonlinear regression. There is no difference between SE and SD when we talk about fitted parameters in the curve fitting. Keywords:SE, SD, parameter, nonlinear curve fit, standard error, standard deviation...
In addition to the development of novel MR methods and contrast mechanisms, the integration of MRI with other imaging modalities that interrogate different aspects of plaque physiology is quickly becoming a reality. As a notable example, the introduction of simultaneous PET/MRI systems allows for the...
Concrete phrase-specific, rapid high-gamma augmentation in the left posterior prefrontal regions may reflect the neuronal activation facilitating prediction and integration of the lexical items, in atop-downmanner, based on their past experience of phrase usage4. Such a cognitive process is expected to...
A study on teachers’ diagnostic competence in text-picture integration showed that teachers tend to overestimate material and tasks with texts and pictures in terms of difficulty, while they tend to underestimate learners’ abilities in this area (McElvany et al., 2012). One consequence of such...
Furthermore, the value of image parameters (also called “biomarkers”) is often sub-optimal due to physical and methodological limitations of the diagnostic methods employed: anatomical imaging, for example, may not detect or characterize a lesion because it is not manifested as a morphological alt...
More recently, a computational technique is being employed utilizing. Nuclear Magnetic Resonance (NMR) or mass spectral analyses of the 13C isotopomer distribution of metabolites, following administration of labeled precursors. These precursors may be uniformly labeled compounds or labeled at specific ...

Foodomics Databases Foodomics is defined as “a discipline that studies the Food and Nutrition domains through the application and integration of advanced -omics technologies to improve consumers’ well-being...
The mathematical details of the treatment and the various techniques, such as numerical integration, along with the analytical treatments have been reported and reviewed elsewhere [241,242]. Indeed, it has been found for Aβ42 that in the absence or low concentration of fibrils, fibril elongation...
