Introduction The overall aim of this study is to compare daytime driving with night-time driving looking at line crossings during self-reported sleepiness and long blinks. The hypothesis is that high levels of self-reported sleepiness (KSS 9) and long blink duration (>0.15 s) will be less associated with critical events during the day-time compared to night-time. Method The study is based on da...

Ever since its introduction by Kane Yee over forty years ago, the finitedifference time-domain (FDTD) method has been a widely-used technique for solving the time-dependent Maxwell’s equations that has also inspired many other methods. This paper presents an alternative approach to these equations in the case of spatially-varying electric permittivity and/or magnetic permeability, based on Kryl...

T he clinical manifestations of patients with mitochondrial DNA (mtDNA) deletions are quite variable. Kearns-Sayre syndrome (KSS; OMIM #530000), the most commonly recognised phenotype, is characterised by the diagnostic triad of progressive external ophthalmoplegia (PEO, OMIM #555000), onset before 20 years of age, pigmentary retinopathy, and one or more of the following: cerebellar ataxia, car...

This paper presents a modification of Krylov Subspace Spectral (KSS) Methods, which build on the work of Golub, Meurant and others pertaining to moments and Gaussian quadrature to produce high-order accurate approximate solutions to the variable-coefficient second-order wave equation. Whereas KSS methods currently use Lanczos iteration to compute the needed quadrature rules, the modification us...

Production of ent-kaurene as a precursor for important signaling molecules such as the gibberellins seems to have arisen early in plant evolution, with corresponding cyclase(s) present in all land plants (i.e., embryophyta). The relevant enzymes seem to represent fusion of the class II diterpene cyclase that produces the intermediate ent-copalyl diphosphate (ent-CPP) and the subsequently acting...

BACKGROUND AND PURPOSE The long-term outcome of patellofemoral arthroplasty is related to progression of femorotibial osteoarthritis with need for conversion to total knee arthroplasty. We investigated whether prior patellofemoral arthroplasty compromises the results of total knee arthroplasty. METHODS 13 patients who had had 14 Richards type II patellofemoral arthroplasties converted to tota...
