Event detection is used to classify recorded gaze points into periods of fixation, saccade, smooth pursuit, blink, and noise. Although there is an overall consensus that current algorithms for event detection have serious flaws and that a de facto standard for event detection does not exist, surprisingly little work has been done to remedy this problem. We suggest a new velocity-based algorithm th
We consider a distribution system consisting of a central warehouse and a group of retailers facing independent stochastic demand. The retailers replenish from the warehouse, and the warehouse from an outside supplier with ample supply. Time is continuous. Most previous studies on inventory control policies for this system have considered stock-based batch-ordering policies. We develop a time-base
We purified a laccase isoenzyme, Lad 1 from Galerina sp. HC1 using a combination of anion exchange- and hydrophobic interaction chromatography. Lad l has a molecular mass of 64 kDa, an isoelectric point of 4, and 3.35 copper atoms/enzyme molecule. The enzyme has features typical of fungal blue laccases. The sequences of two internal peptides were highly similar to reported laccase sequences from o
We present rapidly convergent expressions for the Green's function of the Poisson equation for spherically symmetric systems where the dielectric constant varies discontinuously in the radial direction. These expressions are used in Monte Carlo simulations of various electrolyte systems, and their efficiency is assessed. With only the leading term of the expansion included, a precision of the pola
We report a method using in situ etching to decouple the axial from the radial nanowire growth pathway, independent of other growth parameters. Thereby a wide range of growth parameters can be explored to improve the nanowire properties without concern of tapering or excess structural defects formed during radial growth. We demonstrate the method using etching by HCl during InP nanowire growth. Th
The objective of the Outcome Measures in Rheumatology (OMERACT) Worker Productivity working group is to identify worker productivity outcome measures that meet the requirements of the OMERACT filter. At the OMERACT I I Workshop, we focused on the at-work limitations/productivity component of worker productivity (i.e., presenteeism) an area with diverse conceptualization and instrumentation approac
Evaporative resistance is an important parameter to characterise clothing thermal comfort. However, previous work has focused mainly on either total static or dynamic evaporative resistance. There is a lack of investigation of localised clothing evaporative resistance. The objective of this study was to study localised evaporative resistance using sweating thermal manikins. The individual and inte
OBJECTIVE: To increase the understanding of how definitions of standards for housing design influence the proportion of dwellings not meeting the standards and the proportion of individuals defined as having accessibility problems. METHODS: The sample included old people and their dwellings in three European countries (N = 1,150). Frequencies and percentages were reported and empirical distributio
A modified heat-moisture exchanger that incorporates a reflecting filter for use with partial rebreathing of exhaled volatile anaesthetics has been commercially available since the 1990s. The main advantages of the device are efficient delivery of inhaled sedation to intensive care patients and reduced anaesthetic consumption during anaesthesia. However, elevated arterial CO2 values have been obse
Despite the widespread dissemination of clinical practice guidelines on the prevention and treatment of cardiovascular disease (CVD), CVD causes one third of deaths worldwide and almost half of all deaths in the developed world. It is therefore likely that, although some aspects of CVD management have improved, there is still a significant shortfall between what is known about CVD prevention and w
This thesis describes six empirical investigations of two techniques applied to software inspections, namely reading techniques and fault content estimation techniques. The first part of the thesis presents a series of experiments of a novel reading technique called usage-based reading. The second part investigates fault content estimation applied to the software inspection process. The estimation
Barley is an abundant crop in Europe, which makes its straw residues an interesting cellulose source for ethanol production. Steam pretreatment of the straw followed by enzymatic hydrolysis converts the cellulose to fermentable sugars. Prior to pretreatment the material is impregnated with a catalyst, for example, H2SO4, to enhance enzymatic digestibility of the pretreated straw. Different impregn
PURPOSE: The design concept and the dosimetric characteristics of an applicator system for intraoperative radiation therapy (IORT) with special emphasis on alignment methods, the effect of a plastic scatterer in the beam, radiation leakage, and misalignment dosimetry, are presented in this paper. MATERIALS AND METHODS: A soft-docking system for a linear accelerator, which enables collimation of el
Background: Collagenous colitis is a chronic inflammatory bowel disease accompanied mainly by nonbloody diarrhea. The objectives of treatment are to alleviate the symptoms and minimize the deleterious effects on health-related quality of life (HRQOL). There is still no generally accepted clinical definition of remission or relapse. The purpose of this study was to analyze the impact of bowel sympt
Lumican and fibromodulin compete for collagen type I binding in vitro and fibromodulin-deficient mice have four-fold more lumican in tendons. These observations indicate that homologous sequences in lumican and fibromodulin bind to collagen type I. Here, we demonstrate that lumican binding to collagen type I is mediated mainly by Asp-213 in LRR 7. The mutation D213N in lumican impairs interaction
This study investigates utilization of the Internet in the rehabilitation of people on long-term sick leave with chronic pain and/or burnout. Fifty-five people were randomly assigned to two groups: a treatment group (n = 27) that participated in a rehabilitation course over the Internet and a waiting list group (n = 28). The goals were to improve participants' health and increase quality of life,
Paramagnetic versions of the CLEAR supports were prepared by entrapment of magnetite particles during suspension polymerization of allylamine, trimethylolpropane ethoxylate (14/3 EO/OH) triacrylate, and trimethylolpropane trimethacrylate. Swelling studies in a broad range of solvents showed comparable swelling of magnetic beads and regular CLEAR beads. The application of the magnetic beads as the
This study was aimed at increasing our understanding of environmental and parental factors influencing mode choice for children's journeys to organized leisure activities. Three hundred and fifty-seven Swedish parents of 8-11-year-old children completed a questionnaire and kept a travel diary. The design of urban environment, in which the families lived, was assessed by a group of five experts. By
A spin-echo-modulated small-angle neutron scattering (SEMSANS) instrument in a time-of-flight (TOF) mode will be able to excel at pulsed neutron sources such as the European Spallation Source (ESS), currently under construction. This work compares experimental data from a TOF SEMSANS setup, where a spatial beam modulation of a white beam is obtained using triangular field coils, with Monte Carlo r
