The scaling theory of type I superconductors close to the critical point is discussed. In this theory the exponent α = 0, which signals a heat capacity with a symmetric logarithmic divergence (non-classical behavior) superimposed on a discontinuity (classical behavior). An explicit scaling...

We present an analytical model of Stokes creeping flows in rectangular cavities. In the model, the fluid normal velocity at the wall is zero, while the fluid tangential velocity at the wall differs from the wall velocity. Numerical work is used to validate some of the ideas generated from this...

A nonlinear analysis based on Renyi entropy is applied to electromyography (EMG) time series from back muscles. The time dependence of the entropy of the EMG signal exhibits a crossover from a subdiffusive regime at short times to a plateau at longer times. We argue that this behavior...
