Assessment of vulnerable freshwater ecosystems and various aquatic effluents by means of ecotoxicological assays
(2015)A battery of ecotoxicological assays of different trophic chain levels has been performed for water and sediment samples of two Greek vulnerable freshwater ecosystems (Karla Lake in Thessaly Region and Koronia Lake in ... -
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 ... -
Changes in feeding behavior as possible indicators for the automatic monitoring of health disorders in dairy cows
(2008)Changes in short-term feeding behavior of dairy cows that occur with the onset of the health disorders ketosis, acute locomotory problems, and chronic lameness were investigated using data collected during previous ... -
Clinical and pathological responses of pigs from two genetically diverse commercial lines to porcine reproductive and respiratory syndrome virus infection
(2009)The response to infection from porcine reproductive and respiratory syndrome virus (PRRSV) for 2 genetically diverse commercial pig lines was investigated. Seventy-two pigs from each line, aged 6 wk, were challenged with ... -
Data Driven, Predictive Molecular Dynamics for Nanoscale Flow Simulations under Uncertainty
(2013)For over five decades, molecular dynamics (MD) simulations have helped to elucidate critical mechanisms in a broad range of physiological systems and technological innovations. MD simulations are synergetic with experiments, ... -
Domestication does not narrow MHC diversity in Sus scrofa
(2013)The Major Histocompatibility Complex (MHC) is a multigene family of outstanding polymorphism. MHC molecules bind antigenic peptides in the peptide-binding region (PBR) that consists of five binding pockets (P). In this ... -
Enhancing principal direction divisive clustering
(2010)While data clustering has a long history and a large amount of research has been devoted to the development of numerous clustering techniques, significant challenges still remain. One of the most important of them is ... -
Exploring the assumptions underlying genetic variation in host nematode resistance (Open Access Publication)
(2008)The wide range of genetic parameter estimates for production traits and nematode resistance in sheep obtained from field studies gives rise to much speculation. Using a mathematical model describing host - parasite ... -
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 ... -
Geometrical pre-planning for conformal radiotherapy
(2007)The optimum selection of beams and arcs in conformal techniques is of the outmost importance in modern radiotherapy. In this work we give a description of an analytic method to aid optimum selection, which is based on ... -
A geometry based optimization algorithm for conformal external beam radiotherapy
(2003)A geometric solution of the problem of optimal orientation of beams in conformal external radiotherapy is presented. The method uses geometric derived quantities which consider the intersection volume between organs at ... -
In silico exploration of the effects of host genotype and nutrition on the genetic parameters of lambs challenged with gastrointestinal parasites
(2007)An in silico mathematical model was used to explore the effect of, and the interaction between, (i) nutrition, (ii) genotype for growth and (iii) genotype for resistance, on the estimates of genetic parameters for resistance ... -
Interrelationship among and repeatability of seven stability indices estimated from commercial cotton (Gossypium hirsutum L.) variety evaluation trials in three Mediterranean countries
(2008)Multi-environment trial data are required, to obtain variety stability performance parameters as selection tools for effective cultivar evaluation. The interrelationship among seven stability parameters and their association ... -
Major histocompatibility complex variation at class II DQA locus in the brown hare (Lepus europaeus)
(2009)The major histocompatability complex (MHC) is a multigene family of receptors that bind and present antigenic peptides to T-cells. Genes of the MHC are characterized by an outstanding genetic polymorphism, which is considered ... -
Model-reduction techniques for Bayesian finite element model updating using dynamic response data
(2014)This work presents a strategy for integrating a class of model reduction techniques into a finite element model updating formulation. In particular a Bayesian model updating approach based on a stochastic simulation method ... -
Molecular and phylogenetic analysis of the HPV 16 E4 gene in cervical lesions from women in Greece
(2012)The HPV16 E1(a )E4 protein is thought to contribute to the release of newly formed viral particles from infected epithelia. In order to investigate amino acid mutations in the HPV16 E1(a )E4 protein, the complete E4 ORF ... -
Molecular epidemiology and evolutionary dynamics of Echovirus 3 serotype
(2015)Echovirus 3 (E3) serotype has been related with several neurologic diseases, although it constitutes one of the rarely isolated serotypes, with no report of epidemics in Europe. The aim of the present study was to provide ... -
Prevalence of HPV16 E1-1374 boolean AND 63nt variants in Greek women
(2014)Recent studies have focused on sequence variation of the HPV16 E1 gene. The present study investigates the prevalence of E1-1374<^>63nt duplication in the Greek population, and the sequence variation at the 5 ' end of the ... -
Recombination in primeval genomes: A step forward but still a long leap from maintaining a sizable genome
(2004)A stubborn question in early molecular evolution is how to sustain the "minimum" informational length required for the basic features of life with a putative low-copying fidelity RNA polymerase ribozyme. Proposals to ... -
Recruitment of mitochondrial tRNA genes as auxiliary variability markers for both intra- and inter-species analysis: The paradigm of brown hare (Lepus europaeus)
(2008)We sequenced and analyzed the mitochondrial tRNA(Thr) and tRNA(Pro) genes from brown hare (Lepus europaeus) individuals of different geographic distribution and we investigated the role of various nucleotide substitutions ...
