Nonstationary Optimal Paths and Tails of Prehistory Probability Density in Multistable Stochastic Systems [PDF]

open access: yes, 1997
The tails of prehistory probability density in nonlinear multistable stochastic systems driven by white Gaussian noise, which has been a subject of recent study, are analyzed by employing the concepts of nonstationary optimal fluctuations. Results of numerical simulations evidence that the prehistory probability density is non-Gaussian and highly ...

The Prehistory of Antibiotic Resistance.

open access: yesCold Spring Harbor Perspectives in Medicine, 2016
Antibiotic resistance is a global problem that is reaching crisis levels. The global collection of resistance genes in clinical and environmental samples is the antibiotic "resistome," and is subject to the selective pressure of human activity.

On the performance of birch tar made with different techniques

open access: yesHeritage Science, 2021
Birch tar is one of the oldest adhesives known in human history. Its production has been discussed in the framework of early complex behaviours and sophisticated cognitive capacities. The precise production method used in the Palaeolithic remains unknown
