The question of whether there are biological differences between male and female brains is a fraught one, and political positions and prior expectations seem to have a strong influence on the interpretation of scientific data in this field. This question is relevant to issues of gender differences in the prevalence of psychiatric conditions, including autism, attention deficit hyperactivity dis...

Radiation therapy is widely used for the treatment of brain tumors and may result in cellular, vascular and axonal injury and further behavioral deficits. The non-invasive longitudinal imaging assessment of brain injury caused by radiation therapy is important for determining patient prognoses. Several rodent studies have been performed using magnetic resonance imaging (MRI), but further studie...

We propose a novel q-space imaging method called generalized q-space imaging (GQI), which is derived from the Fourier transform relationship between the MR signals and underlying diffusion displacement [1]. The method is characterized by being independent of the q-space sampling schemes, enabling us to use either q-ball imaging (QBI) [2] or diffusion spectrum imaging (DSI) dataset [3]. The accu...

The study of groundwater quality is typically conducted using water indices such as the Groundwater Quality Index (GQI) or GroundWater (GWQI). are calculated field data and a scoring system that uses ratios constituents to prescribed standards weights based on each constituent’s relative importance. results obtained by this procedure suffer from inherent subjectivity, consequently may have some...

Abstract The objective of this work was to propose a new stopping criterion shorten the computing time PampaPlus genetic improvement software, while maximizing qualification index (GQI) progeny, controlling inbreeding, and avoiding unintended culling. Data from two beef-cattle herds integrating were used. Five mating scenarios built using different numbers sires (9 37) dams (142 568). analyzed ...

BACKGROUND The geometric organization of myocytes in the ventricular wall comprises the structural underpinnings of cardiac mechanical function. Cardiac myosin binding protein-C (MYBPC3) is a sarcomeric protein, for which phosphorylation modulates myofilament binding, sarcomere morphology, and myocyte alignment in the ventricular wall. To elucidate the mechanisms by which MYBPC3 phospho-regulat...

A diffusion deconvolution method is proposed to apply deconvolution to the diffusion orientation distribution function (dODF) and calculate the fiber orientation distribution function (fODF), which is defined as the orientation distribution of the fiber spin density. The dODF can be obtained from q-space imaging methods such as q-ball imaging (QBI), diffusion spectrum imaging (DSI), and general...

Fiber orientation is the key information in diffusion tractography. Several deconvolution methods have been proposed to obtain fiber orientations by estimating a fiber orientation distribution function (ODF). However, the L 2 regularization used in deconvolution often leads to false fibers that compromise the specificity of the results. To address this problem, we propose a method called diffus...
