    On multi-strain model for Hepatitis C

    In this paper we present a multi-strain model for hepatitis C virus (HCV) including an immune response term. The model is presented and discussed. Also we argue that the added multi-strain term represents some...

    Discriminating between ADHD adults and controls using independent ERP components and a support vector machine: a validation study

    There are numerous event-related potential (ERP) studies in relation to attention-deficit hyperactivity disorder (ADHD), and a substantial number of ERP correlates of the disorder have been identified. However...

    New method for analysis of nonstationary signals

    Analysis of signals by means of symbolic methods consists in calculating a measure of signal complexity, for example informational entropy or Lempel-Ziv algorithmic complexity. For construction of these entrop...

    Pulse Decomposition Analysis of the digital arterial pulse during hemorrhage simulation

    Markers of temporal changes in central blood volume are required to non-invasively detect hemorrhage and the onset of hemorrhagic shock. Recent work suggests that pulse pressure may be such a marker. A new app...

    On modeling two immune effectors two strain antigen interaction

    In this paper we consider the fractional order model with two immune effectors interacting with two strain antigen. The systems may explain the recurrence of some diseases e.g. tuberculosis (TB). The stability...

    Characterization of chaotic dynamics in the human menstrual cycle

    The human menstrual cycle is known to exhibit a significant amount of unexplained variability. This variation is typically dismissed as random fluctuations in an otherwise periodic and predictable system. Give...
