Blood oxygenation level dependent (BOLD) functional magnetic resonance imaging (fMRI) is a powerful technique, typically based on the statistical analysis of the magnitude component of the complex time-series. Here, we additionally interrogated the phase data of the fMRI time-series and used quantitative susceptibility mapping (QSM) in order to investigate the potential of functional QSM (fQSM)...

Accuracy Assessment of GLM and FDA Models for Land Subsidence Susceptibility Mapping in Semnan Plain
The mechanism of land subsidence and soil deformation is the dissipation of the excess pore water pressure and the compaction of the soil skeleton under the effect of natural or man-made factors. Land subsidence has occurred in more of 300 plains of Iran, and Semnan Plain is one of the most important areas that face to this phenomenon. The aim of current research was land subsidence susceptibil...
Landslide mapping is one of the approaches (which can be) used to define the slope stable critical areas and the maps prepared based on this demarcating are used in desining sustainable development. The purpose of this study is to compare the landslide susceptibility mapping models based on Fuzzy logic, Information value and area Density applied in the Chamsangar watershed. According to the tec...
مقایسۀ نقشه های حساسیت زمین لغزش با استفاده از مدل رگرسیون لجستیک (LR) و مدل عمومی تجمیع یافته (GAM)
Landslide is one of the most common natural disasters that endanger the lives and properties of people in mountainous areas. Therefore, identification of risk exposure areas of landslide is essential to prevent and reduce damages by landslides. The purpose of this study is compared to logistic regression (LR) and generalized additive models (GAM) and the evaluation of their performance for land...
Background Iron deficiency can be related to patients with chronic heart failure. Although T2* mapping by MRI could be used as a non-invasive interrogator for the assessment of the iron loading, unfortunately the result is only with limited success. Quantitative susceptibility mapping is a further development using susceptibility weighted image. Previous studies suggested a strong linear co-rel...
In this paper we derive a simple parametrization of the cycling method developed by us in our earlier work. The new method, called renormalization group (RG) mapping, consists of a series of carefully tuned APEsmearing steps. We study the relation between cycling and RG mapping. We also investigate in detail how smooth instantons and instanton-antiinstanton pairs behave under the RG mapping tra...
