An evaluative methodology and five accompanying performance measures were developed to quantitatively assess the performance of the skeleton projection algorithm constituting the heart of tract-based spatial statistics (TBSS). The performance measures were designed to quantify the accuracy of skeleton projection in its indented task of alleviating any residual misalignment that may remain after...

Zeolites/molecular sieves with uniform, molecular-sized pores are important for many adsorption-based separation processes. Pore size gaps, however, exist in the current zeolite family. This leads to a great challenge of separating molecules with size differences at ~0.01 nm level. Here, we report a novel concept, pore misalignment, to form a continuously adjustable, molecular-sieving "gate" at...

Recent work showed that the single-subunit T7 RNA polymerase (RNAP) can generate misincorporation errors by a mechanism that involves misalignment of the DNA template strand. Here, we show that the same mechanism can produce errors during transcription by the multisubunit yeast RNAP II and bacterial RNAPs. Fluorescence spectroscopy reveals a reorganization of the template strand during this pro...

PURPOSE To measure quantitatively the change in the coaxial fundus reflex with varying degrees of ocular misalignment. METHODS The coaxial fundus reflex was imaged with a charge coupled device camera under conditions of simulated ocular misalignment ranging from 0 degrees to 7 degrees of fixation eccentricity. The effects of refractive error and pupil size were controlled. Average gray scale ...

This paper deals with a generic methodology to evaluate the magnetic parameters of contactless power transfer systems. Neumann’s integral has been used to create a matrix method that can model the magnetics of single coils (circle, square, rectangle). The principle of superposition has been utilised to extend the theory to multi-coil geometries such as double circular, double rectangle and doub...

We study supersymmetric models without R parity and with universal soft supersymmetry breaking terms. We show that as a result of the renormalization group flow of the parameters, a misalignment between the directions in field space of the down-type Higgs vacuum expectation value vd and of the μ term is always generated. This misalignment induces a mixing between the neutrinos and the neutralin...

The purpose of this work is to understand, quantify and minimize the impact of the emission-transmission misalignment which has been reported as a source of artefacts in cardiac PET/CT. A new and fully automatic correction algorithm is proposed to realign the μ-map contour of the left ventricle to the measured PET. PET/CT NH3 rest/stress scans were acquired for 16 patients in order to evaluate ...

The nanowire crossbar is a promising nanotechnology for assembling memories and circuits. In both, a small number of lithographically produced mesoscale wires (MWs) must control a large number of nanoscale wires (NWs). Previous strategies for achieving this have been vunerable to misalignment. In this paper, we introduce core-shell NWs, which eliminate misalignment errors. We also give a two-st...
