Acute imaging does not improve ASTRAL score's accuracy despite having a prognostic value
(2014)Background The ASTRAL score was recently shown to reliably predict three-month functional outcome in patients with acute ischemic stroke. Aim The study aims to investigate whether information from multimodal imaging increases ... -
Association of ischaemic stroke subtype with long-term cardiovascular events
(2014)Background and purpose: There is no strong evidence that all ischaemic stroke types are associated with high cardiovascular risk. Our aim was to investigate whether all ischaemic stroke types are associated with high ... -
Bayesian uncertainty quantification and propagation for discrete element simulations of granular materials
(2014)Predictions in the behavior of granular materials using Discrete Element Methods (DEM) hinge on the employed interaction potentials. Here we introduce a data driven, Bayesian framework to quantify DEM predictions. Our ... -
Causal ordering of physical self-concept and exercise behavior: Reciprocal effects model and the influence of physical education teachers
(2006)Does prior physical self-concept influence subsequent exercise behavior? On the basis of a large sample of physical education classes (2,786 students, 200 classes, 67 teachers) collected early (Time 1) and late (Time 2) ... -
CHLfuzzy: a spreadsheet tool for the fuzzy modeling of chlorophyll concentrations in coastal lagoons
(2008)CHLFuzzy is a user-friendly, flexible, multiple-input single-output Takagi-Sugeno fuzzy rule based model developed in a MS-Excel (R) spreadsheet environment. The model receives a raw dataset consisting of four predictor ... -
Common femoral artery intima-media thickness as marker for cardiovascular disease in asymptomatic adults
(2009)Background: The common carotid intima-media thickness (IMT) is considered as a marker of cardiovascular disease, while the value of the common femoral IMT is not well defined. The aim of the present study was to investigate ... -
Diagnostic value of anti-cyclic citrullinated peptide antibodies in Greek patients with rheumatoid arthritis
(2007)Background: Anti-cyclic citrullinated peptide (anti-CCP) antibodies have been of diagnostic value in Northern European Caucasian patients with rheumatoid arthritis ( RA). In these populations, anti-CCP antibodies are ... -
Differences in smoking attitudes of adolescents and young adults
(2007)This study employed the Theory of Planned Behavior to examine the differences between adolescent (n = 182) and young adults (n = 209) in their intention to smoke and examined possible differences. Analysis showed that young ... -
Effect of vent arrangement on windward ventilation of a tunnel greenhouse
(2004)The effect of ventilation configuration of a tunnel greenhouse with crop on airflow and temperature patterns was numerically investigated using a commercial computational fluid dynamics (CFD) code. The numerical model was ... -
Estimation of fatigue crack growth retardation due to crack branching
(2004)Quantitative analysis is provided to estimate the reduction of fatigue crack growth rate due to overload crack branching. A recent mixed-mode fatigue crack growth model based on the dilatational component of the accumulated ... -
Femoral head osteonecrosis: Volumetric MRI assessment and outcome
(2007)Effective treatment of femoral head osteonecrosis (FHON) requires early diagnosis and accurate assessment of the disease severity. The ability to predict in the early stages the risk of collapse is important for selecting ... -
Forest classification trees and forest support vector machines algorithms: Demonstration using microarray data
(2010)Classification into multiple classes when the measured variables are outnumbered is a major methodological challenge in -omics studies. Two algorithms that overcome the dimensionality problem are presented: the forest ... -
Greek students' attitudes toward physical activity and health-related behavior
(2003)A three-wave study over one year with 882 adolescents, aged 10 to 16 years at the initial testing, examined psychosocial variables regarding four health-related behaviors: exercise, eating fruit, smoking, and drug use. ... -
Implementation of chemometrics for quality control and authentication of meat and meat products
(2003)Multivariate analysis has been established as a very powerful and effective tool in classifying and grouping individual products. Principal Component Analysis, Canonical analysis, Cluster and Partial Least Squares were ... -
Interfacial shear stress in wavy stratified gas-liquid flow in horizontal pipes
(2013)The scope of this study was to improve the Andritsos-Hanratty model for estimating interfacial friction factor and pressure drop in horizontal stratified gas-liquid two-phase flow. New experimental results (focusing on the ... -
Large-scale meta-analysis of genome-wide association data identifies six new risk loci for Parkinson's disease
(2014)We conducted a meta-analysis of Parkinson's disease genome-wide association studies using a common set of 7,893,274 variants across 13,708 cases and 95,282 controls. Twenty-six loci were identified as having genome-wide ... -
Meta-analysis for ranked discovery datasets: Theoretical framework and empirical demonstration for microarrays
(2008)The combination of results from different large-scale datasets of multidimensional biological signals (such as gene expression profiling) presents a major challenge. Methodologies are needed that can efficiently combine ... -
Modelling the Environmental Effects of Railway Vibrations from Different Types of Rolling Stock: A Numerical Study
(2015)This paper analyses the influence of rolling stock dynamics on ground-borne vibration levels. Four vehicle types (Thalys, German ICE, Eurostar, and Belgian freight trains) are investigated using a multibody approach. First, ... -
A multilevel approach to motivational climate in physical education and sport settings: An individual or a group level construct?
(2004)Motivational climate is inherently a group-level construct so that longitudinal, multilevel designs are needed to evaluate its effects on subsequent outcomes. Based on a large sample of physical education classes (2,786 ...
