Given several different populations, the relative proportions of each in the high (or low) end of the distribution of a given characteristic are often more important than the overall average values or standard deviations. In the case of two different

A recent article by Alexopoulos and Leontsinis presented empirical evidence that the first digits of the distances from the Earth to galaxies are a reasonably good fit to the probabilities predicted by Benford’s law, the well known logarithmic stat

The decay rates of damped bistable quantum systems show at low temperatures multi-resonant behavior as a function of an external bias. These resonances are connected with steps in the response of the double well system to strong external forcing and

A wealth of research on stochastic resonance (SR) during the past decade has led to different ways of defining this phenomenon. Most prominent are measures based on the response function and on the residence-time distribution function. While the theo

Gibbs entropy is invariant for the Baker map. A Jordan basis spectral decomposition of the Baker Frobenius-Perron operator suggests that any initial density evolves to the stationary density that has maximal entropy. This entropy conundrum is resolve

A nonperturbative theory for quasiadiabatic time evolution in quantum systems is presented. The dynamics of the passage through an avoided level crossing is given by a nonperturbative alternative to the Landau-Zener theory used for diatomic predissoc

We numerically demonstrate that the response of a damped quantum particle in a bistable potential to a strong time-dependent force exhibits steps at some specific values of the force. They can be associated with avoided level crossings in the spectru

A unified model is presented for rectified Brownian movement as the mechanism for a variety of putatively chemomechanical energy conversions in molecular and cell biology. The model is established by a detailed analysis of ubiquinone transport in ele

Many solar systems in the universe may be expected to contain rocky planets that have accreted organic compounds. These compounds are likely to be universally found. In addition, the chemistry of sulfur, phosphorus, and iron is likely to dominate ene
