The Dynamics of a Genetic Algorithm for a Simple Learning Problem [PDF]

open access: yes, 1996
A formalism for describing the dynamics of Genetic Algorithms (GAs) using methods from statistical mechanics is applied to the problem of generalization in a perceptron with binary weights.

Whole MILC: Generalizing Learned Dynamics Across Tasks, Datasets, and Populations [PDF]

open access: yes, 2020
Behavioral changes are the earliest signs of a mental disorder, but arguably, the dynamics of brain function gets affected even earlier. Subsequently, spatio-temporal structure of disorder-specific dynamics is crucial for early diagnosis and understanding the disorder mechanism.

Mapping the evolution of mitochondrial complex I through structural variation

open access: yesFEBS Letters, EarlyView.
Respiratory complex I (CI) is crucial for bioenergetic metabolism in many prokaryotes and eukaryotes. It is composed of a conserved set of core subunits and additional accessory subunits that vary depending on the organism. Here, we categorize CI subunits from available structures to map the evolution of CI across eukaryotes. Respiratory complex I (CI)

Transient inconsistency between population density and fisheries yields without bycatch species extinction

open access: yesEcology and Evolution, 2020
Recent studies have demonstrated the great advantages of marine reserves in solving bycatch problems by maintaining the persistence (i.e., avoid extinction) of endangered species without sacrificing the fisheries yields of target species.

Invasion and effective size of graph-structured populations. [PDF]

open access: yesPLoS Computational Biology, 2018
Population structure can strongly affect evolutionary dynamics. The most general way to describe population structures are graphs. An important observable on evolutionary graphs is the probability that a novel mutation spreads through the entire ...

Dressed-State Approach to Population Trapping in the Jaynes-Cummings Model [PDF]

open access: yes, 1999
The phenomenon of atomic population trapping in the Jaynes-Cummings Model is analysed from a dressed-state point of view. A general condition for the occurrence of partial or total trapping from an arbitrary, pure initial atom-field state is obtained in ...
