    • Bifurcation Analysis of Gene Regulatory Circuits Subject to Copy Number Variation 

      Mileyko, Yuriy; Weitz, Joshua S (2010)
      Gene regulatory networks are comprised of many small gene circuits. Understanding expression dynamics of gene circuits for broad ranges of parameter space may provide insight into the behavior of larger regulatory networks ...
    • Chaos for cardiac arrhythmias through a one-dimensional modulation equation for alternans 

      Dai, Shu; Schaeffer, David G (2010)
      Instabilities in cardiac dynamics have been widely investigated in recent years. One facet of this work has studied chaotic behavior, especially possible correlations with fatal arrhythmias. Previously chaotic behavior was ...
    • Computational and Analytic Perspectives on the Drift Paradox 

      Pasour, VB; Ellner, SP (2010)
      The fact that many small aquatic and marine organisms manage to persist in their native environments in the presence of constant advection into unfavorable habitat is known as the "drift paradox." Although advection may ...
    • Dynamics of electroencephalogram entropy and pitfalls of scaling detection 

      Ignaccolo, M; Latka, M; Jernajczyk, W; Grigolini, P; West, BJ (2010)
      In recent studies a number of research groups have determined that human electroencephalograms (EEG) have scaling properties. In particular, a crossover between two regions with different scaling exponents has been reported. ...
    • Spontaneous brain activity as a source of ideal 1/f noise 

      Allegrini, Paolo; Menicucci, Danilo; Bedini, Remo; Fronzoni, Leone; Gemignani, Angelo; Grigolini, Paolo; West, Bruce J; ... (8 authors) (2009)
      We study the electroencephalogram (EEG) of 30 closed-eye awake subjects with a technique of analysis recently proposed to detect punctual events signaling rapid transitions between different metastable states. After ...
