A combined LS-SVM & MLR QSAR workflow for predicting the inhibition of CXCR3 receptor by quinazolinone analogs
(2010)AnovelQSARworkflowis constructed that combines MLR with LS-SVM classification techniques for the identification of quinazolinone analogs as "active" or "nonactive" CXCR3 antagonists. The accuracy of the LS-SVM classification ...

A computationally fast measure of epistasis for 2 SNPs and a categorical phenotype.
(2010)Complex diseases may be caused by interactions or combined effects between multiple genetic and environmental factors. One of the main limitations of testing for interaction between genetic loci in large whole genome studies ...

First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.
(2011)Carotid plaques have been associated with ipsilateral neurological symptoms. High-resolution ultrasound can provide information not only on the degree of carotid artery stenosis but also on the characteristics of the ...

Frailty models for arbitrarily censored and truncated data
(2004)In this paper, we propose a frailty model for statistical inference in the case where we are faced with arbitrarily censored and truncated data. Our results extend those of Alioum and Commenges (1996), who developed a ...

Island species richness increases with habitat diversity
(2009)Species richness is commonly thought to increase with habitat diversity. However, a recent theoretical model aiming to unify niche and island biogeography theories predicted a hump-shaped relationship between richness and ...

Novel approach to fast determination of cholesterol oxidation products in Cypriot foodstuffs using ultra-performance liquid chromatography-tandem mass spectrometry
(2016)This paper reports the development and validation of a new method based on ultra-performance LC coupled to MS/MS for the simultaneous determination of four cholesterol oxidation products (COPs) in foodstuffs in only 4.1 ...

Order-restricted semiparametric inference for the power bias model
(2010)The power bias model, a generalization of length-biased sampling, is introduced and investigated in detail. In particular, attention is focused on order-restricted inference. We show that the power bias model is an example ...

Patterns of transmitted HIV drug resistance in Europe vary by risk group
(2014)Background: In Europe, a continuous programme (SPREAD) has been in place for ten years to study transmission of drug resistant HIV. We analysed time trends of transmitted drug resistance mutations (TDRM) in relation to the ...

Prediction of the time period of stroke based on ultrasound image analysis of initially asymptomatic carotid plaques
(Institute of Electrical and Electronics Engineers Inc., 2015)Non-invasive ultrasound imaging of carotid plaques can provide information on the characteristics of the arterial wall including the size, morphology and texture of the atherosclerotic plaques. Several studies were carried ...

Qualitative and quantitative determination of COPs in cypriot meat samples using HPLC determination of the most effective sample preparation procedure
(2013)This research work describes the development of a fast high-performance liquid chromatography method for the simultaneous determination of five important cholesterol oxidation products (COPs). The influence of various ...

Testing alternative hypotheses for evolutionary diversification in an african songbird: Rainforest refugia versus ecological gradients
(2011)Geographic isolation in rainforest refugia and local adaptation to ecological gradients may both be important drivers of evolutionary diversification. However, their relative importance and the underlying mechanisms of ...

Variable selection strategies in survival models with multiple imputations
(2007)In this paper, the variable selection strategies (criteria) are thoroughly discussed and their use in various survival models is investigated. The asymptotic efficiency property, in the sense of Shibata Ann Stat 8: 147-164, ...
