Fluctuating asymmetry of bilateral morphological traits is the result of prenatal developmental instability and has been shown to be greater in organisms having more homozygous genotypes (aabb vs. AaBb, for example). This expected increase in fluctuating asymmetry has been found among individuals having a high degree of liability for schizophrenia, as this disorder appears to have a polygenic basis.
Indonesia is the largest archipelago in the world, consisting of five main islands and 17,500 smaller islands, spread across three seismic belts that run throughout the country. Indonesia is extremely prone to disasters, both natural and manmade. With a total population of nearly 250 million people, Indonesia's Muslim community exceeds 180 million - the largest Muslim population in the world. On December 26, 2004 an earthquake and tsunami hit Aceh resulting in an estimated 165,00 deaths (mostly Muslims) and half a million people displaced.

We show that image registration using conventional interpolation and summation approximations of continuous integrals can generally fail because of resampling artifacts. These artifacts negatively affect the accuracy of registration by producing local optima, altering the gradient, shifting the global optimum, and making rigid registration asymmetric. In this paper, after an extensive literature review, we demonstrate the causes of the artifacts by comparing inclusion and avoidance of resampling analytically.

OBJECTIVE: An ink pad and paper, pressure-sensitive platforms, and photography have previously been used to collect footprint data used in clinical assessment. Digital scanners have been widely used more recently to collect such data. The purpose of this study was to evaluate the intra- and interrater reliability of a flatbed digital image scanning technology to capture footprint data. METHODS: This study used a repeated-measures design on 32 (16 male 16 female) healthy subjects.
