Independently folded domains in RNAs frequently adopt identical tertiary structures regardless of whether they are in isolation or are part of larger RNA molecules. This is exemplified by the P15 domain in the RNA subunit (RPR) of the universally conserved endoribonuclease P, which is involved in the processing of tRNA precursors. One of its domains, encompassing the P15 loop, binds to the 3'-e...

Recent two dimensional nuclear magnetic resonance (NMR) techniques access exchange in pore structures through surface relaxation and diffusion based relaxation [1-4]. This research applies these techniques to measure pore changes due to biofilm growth and the impact this growth has on diffusion transport. The porous media used in this study are model beadpacks constructed from borosilicate glas...

This paper proposes a method for local deformation analysis of the heart's left ventricle (LV) which is of an utmost interest in characterizing the myocardium disease extent and severity. Our method is based on regional curvature variation calculation using the Hotelling T2 two samples difference metric. Our approach is validated on real data obtained from myocardial scintigraphy imaging techni...
