The Effect of Metric Selection on Averaging Diffusion Tensors – When and Why do Tensors Swell?
Introduction In many diffusion tensor imaging (DTI) analysis methods, including registration, realignment and re-slicing, averaging or interpolating tensors is required. Defining how distance is measured between tensors, through a metric, determines the interpolation results. It was demonstrated that when using a conventional Euclidean metric, the resulted tensor might have a larger volume (det...
متن کاملOn Clays
Base-exchange determinations were made on selected clays of the montmorill0niteillite group to test this method as an analytical tool for the analysis of mixed-layer aggregates. The relatively rapid manganese method developed by Bower and Truog was used and its precision determined oll monodisperse, monomineralic fractions and monodisperse fractions of prepared mixtures of illite and montmorill...
متن کاملNeurons that swell
ells that passively swell and contract with changes in osmolarity are the key to detecting those changes, say Most cells have at least two mechanisms for maintaining homeostasis in response to changes in salt concentrations. Without these mechanisms, osmotic forces take over: more water and thus less salt outside cells leads water to flood into a cell. But this swelling doesn't occur in most ce...
متن کاملMitosis is swell
Cell volume and dry mass are typically correlated. However, in this issue, Zlotek-Zlotkiewicz et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505056) and Son et al. (2015. J. Cell Biol. http://dx.doi.org/10.1083/jcb.201505058) use new live-cell techniques to show that entry to mitosis coincides with rapid cell swelling, which is reversed before division.
متن کاملESR of clays
Electron spin resonance (ESR) spectroscopy has contributed significantly to the identification and characterization pf paramagnetic impurities associated with clays, Following a brief discussion of the general principles of the technique, a review is given of the application of ESR to the study of those paramagnetic species (chiefly iron and radiation-induced lattice defects) located either wit...
