Circadian rhythms are daily oscillations in behaviors that persist in constant light/dark conditions with periods close to 24 h. A striking feature of these rhythms is that their periods remain fairly constant over a wide range of physiological temperatures, a feature called temperature compensation. Although circadian rhythms have been associated with periodic oscillations in mRNA and protein ...

We present a compensated Horner scheme, that is an accurate and fast algorithm to evaluate univariate polynomials in floating point arithmetic. The accuracy of the computed result is similar to the one given by the Horner scheme computed in twice the working precision. This compensated Horner scheme runs at least as fast as existing implementations producing the same output accuracy. We also pr...

Motion Compensated Noise Reduction

In this paper we present a novel motion compensated deinterlacing scheme based on a joint variational framework of motion estimation and creation of new pixel values. We propose a specific energy formulation for that purpose, optimized by solving corresponding EulerLagrange equations. The difficult issue of calculating motion on interlaced image sequences is addressed and the presented algorith...

Introduction: Motion during data acquisition can seriously degrade image quality. Motion compensated reconstruction can restore image quality if the motion is measured with suitable navigator signals. We present a new scheme for motion compensated reconstruction which can be applied to segmented Cartesian acquisitions (e.g. TSE, TFE). It can be combined with parallel imaging and is fast because...

To the Editor: which in the absence of anemia increases th rate of red blood cell In a recent excellent review on iron balance in humans,' Dr ClemProduction.'" ent Finch briefly discussed compensated hemolytic anemia in pa. Dr Finch states in his review without a specific reference that the tients with hereditary spherocytosis. For years I have been interested erythropoietin titer in this c...

Deleterious or 'disease-associated' mutations are mutations that lead to disease with high phenotype penetrance: they are inherited in a simple Mendelian manner, or, in the case of cancer, accumulate in somatic cells leading directly to disease. However, in some cases, the amino acid that is substituted resulting in disease is the wild-type native residue in the functionally equivalent protein ...
