Open AccessOn the thermodynamic entropy in the microcanonical ensemble of classical systems
We demonstrate that the surface entropy given by the volume of an energy shell in the phase space can be the thermodynamically consistent entropy in a classical microcanonical ensemble if the thickness of the ...

Principles for the emergence of computational properties in a complex system
Understanding how a natural computing system like the brain works or learns requires an approach from a different point of view than an artificially developed computing system. Such a natural computing system ...
