Rethinking Life and Predicting Its Origin

open access: yesTheory in Biosciences, 2021
The definition, origin and recreation of life remain elusive. As others have suggested, only once we put life into reductionist physical terms will we be able to solve those questions. To that end, this work proposes the phenomenon of life to be the product of two dissipative mechanisms.

Fatigue life prediction under realistic loading conditions

open access: yes, 2020
The accurate modeling of the fatigue behavior of composite materials under constant amplitude (CA) cyclic stress is in itself a difficult task but when loading is of variable amplitude (VA), the situation is even more complicated since an appropriate ...
