Computerized texture analysis of carotid plaque ultrasonic images can identify unstable plaques associated with ipsilateral neurological symptoms

Kakkos, Stavros K.; Nicolaïdes, Andrew N.; Kyriacou, Efthyvoulos C.; Daskalopoulou, Stella Styliani; Sabetai, Michael; Pattichis, Constantinos S.; Geroulakos, George; Griffin, Maura B.; Thomas, Dominique (2011)

We estimated the value of objective, computerized texture analysis of ultrasonic images in distinguishing carotid plaques associated with neurological ipsilateral symptoms (amaurosis fugax [AmF

First and second order statistical texture features in carotid plaque image analysis: preliminary results from ongoing research.

Kyriacou, Efthyvoulos C.; Nicolaïdes, Andrew N.; Pattichis, Constantinos S.; Petroudi, Styliani; Pattichis, Marios S.; Griffin, Maura B.; Kakkos, Stavros K.; Makris, Gregory C. (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

Huber-Carol, C.; Vonta, Filia (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 ...

Manual and automated media and intima thickness measurements of the common carotid artery

Loizou, Christos P.; Pattichis, Constantinos S.; Nicolaïdes, Andrew N.; Pantzaris, Marios C. (2009)

The intima-media thickness (IMT) of the common carotid artery (CCA) is widely used as an early indicator of the development of cardiovascular disease (CVD). It was proposed but not thoroughly investigated that the media ...

Measuring input synchrony in the Ornstein-Uhlenbeck neuronal model through input parameter estimation

Koutsou, Achilleas; Kanev, J.; Christodoulou, Chris C. (2013)

We present a method of estimating the input parameters and through them, the input synchrony, of a stochastic leaky integrate-and-fire neuronal model based on the Ornstein-Uhlenbeck process when it is driven by time-dependent ...

A novel QSAR model for predicting induction of apoptosis by 4-aryl-4H-chromenes

Afantitis, Antreas; Melagraki, G.; Sarimveis, H.; Koutentis, Panayiotis Andreas; Markopoulos, J.; Igglessi-Markopoulou, O. (2006)

A linear quantitative structure-activity relationship (QSAR) model is presented for modeling and predicting induction of apoptosis by 4-aryl-4H-chromenes. The model was produced by using the multiple linear regression (MLR) ...

Variable selection strategies in survival models with multiple imputations

Vonta, Filia; Karagrigoriou, Alex (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, ...
