Revisiting and expanding the meta-analysis of variation: The log coefficient of variation ratio KU Leuven
Meta-analyses are often used to estimate the relative average values of a quantitative outcome in two groups (eg, control and experimental groups). However, they may also examine the relative variability (variance) of those groups. For such comparisons, two relatively new effect size statistics, the log-transformed "variability ratio" (the ratio of two standard deviations; lnVR) and the log-transformed "coefficients of variation ratio" (the ...
Hidden genetic variation in Stargardt disease : novel copy number variations, cis-regulatory and deep-intronic splice variants within the ABCA4 locus Ghent University
Hidden genetic variation in retinal dystrophies : exploring the contribution of copy number variations Ghent University
Hidden genetic variation in LCA9-associated congenital blindness explained by 5U+2032UTR mutations and copy-number variations of NMNAT1 Ghent University
Mobile monitoring for mapping spatial variation in urban air quality: development and validation of a methodology based on an extensive dataset Ghent University
A Log-Euclidean and Total Variation based Variational Framework for Computational Sonography KU Leuven
© COPYRIGHT SPIE. Downloading of the abstract is permitted for personal use only. We propose a spatial compounding technique and variational framework to improve 3D ultrasound image quality by compositing multiple ultrasound volumes acquired from different probe orientations. In the composite volume, instead of intensity values, we estimate a tensor at every voxel. The resultant tensor image encapsulates the directional information of the ...
Genomic variation at the tips of the adaptive radiation of Darwin's finches KU Leuven
Adaptive radiation unfolds as selection acts on the genetic variation underlying functional traits. The nature of this variation can be revealed by studying the tips of an ongoing adaptive radiation. We studied genomic variation at the tips of the Darwin's finch radiation; specifically focusing on polymorphism within, and variation among, three sympatric species of the genus Geospiza. Using restriction site-associated DNA (RAD-seq), we ...
DC/DC Converter Dead-Time Variation Analysis and Far-Field Radiation Estimation KU Leuven
© 2015 IEEE. This paper presents the dead-time variation analysis and far-field radiation estimation of a DC/DC converter. The critical factors influencing the dead-time variation are identified and their statistical distributions are defined. The statistical distribution of the MOSFET parasitic capacitances is optimized to match the values obtained by measurements. The packaging process variation together with the variation of the printed ...
