White matter structures composed of myelinated axons in the living human brain are primarily studied by diffusion-weighted MRI (dMRI). These long-range projections are typically characterized in a two-step process: dMRI signal is used to estimate the orientation of axon segments within each voxel, then these local orientations are linked together to estimate the spatial extent of putative white...

For the purpose of the ISBI HARDI reconstruction challenge 2013 and for the categories DTI and HARDI acquisitions, we reconstructed the diffusion datasets using two well established methods: a) Spherical Deconvolution Transform (SDT) [1], [2] and b) Constrained Spherical Deconvolution (CSD) [3]. The SDT is a sharpening operation which transforms the smooth diffusion ODF into a sharper fiber ODF...

An oviduct-specific, estrus-associated glycoprotein (EAP) of 85-95 kDa is detectable in both conditioned medium (CM) from oviductal explants and cannula-derived oviductal fluid (ODF). The objectives of this study were to purify EAP from both ODF and CM, to characterize the glycosylation of EAP, and to localize binding of EAP on sperm. EAP was purified from ODF by ammonium sulfate precipitation ...

For the purpose of applying a modified 5083 alloy (New 5083M alloy) with high Mg content in various automotive sheet parts, stretch forming behavior was studied tensile mode at wide range processing conditions. The tests were conducted by using test machine under temperature ranges 100–400 °C and strain rate 0.001–1 s?1. results showed that has superior mechanical properties to commercial eleva...

High angular resolution diffusion imaging (HARDI) is a powerful variant of diffusion MRI, which images the 3D profile of diffusion at each imaged location in the brain. At each voxel, this leads to an orientation density function (ODF) expressing the probability density of water diffusion in each direction on the unit sphere. As diffusion is greatest along the brain’s axons, these functions are...

Introduction Several deconvolution methods have been proposed to increase the angular resolution of HARDI or QBI [1][2]. However, there is no deconvolution method directly applied to diffusion ODF without resorting to spherical decomposition. In this study, we developed a deconvolution method that could be directly applied to diffusion ODF, thus extending its applicability to other q-space meth...
