Introduction: In this paper, a novel complexity measure is proposed to detect dynamical changes in nonlinear systems using ordinal pattern analysis of time series data taken from the system. Epilepsy is considered as a dynamical change in nonlinear and complex brain system. The ability of the proposed measure for characterizing the normal and epileptic EEG signals when the signal is short or is...

Structural texture measures are used to address three aspects of early detection of breast cancer in screening mammograms: detection of microcalcification, detection and classification of clustered microcalcification as benign or malignant, and the detection of invasive lobular carcinoma. The use of structural texture features replaces the task of initial detection of complex and poorly modelle...

The problem of optimizing sentinel surveillance in networks is to find the nodes where an emerging disease outbreak can be discovered early or reliably. Whether the emphasis should be on early or reliable detection depends on the scenario in question. We investigate three objective measures quantifying the performance of nodes in sentinel surveillance—the time to detection or extinction, the ti...
