Recognition Dynamics in the Brain under the Free Energy Principle [PDF]

open access: yesNeural Computation, 2018
Abstract We formulate the computational processes of perception in the framework of the principle of least action by postulating the theoretical action as a time integral of the variational free energy in the neurosciences. The free energy principle is accordingly rephrased, on autopoetic grounds, as follows: all viable organisms attempt

Cultural affordances: Scaffolding local worlds through shared intentionality and regimes of attention

open access: yesFrontiers in Psychology, 2016
In this paper we outline a framework for the study of the mechanisms involved in the engagement of human agents with cultural affordances. Our aim is to better understand how culture and context interact with human biology to shape human behavior ...

From energy provision to protein synthesis: Tunnelling nanotubes as mediators of intercellular metabolic cooperation in cancer

open access: yesFEBS Open Bio, EarlyView.
The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

A Factor Graph Description of Deep Temporal Active Inference

open access: yesFrontiers in Computational Neuroscience, 2017
Active inference is a corollary of the Free Energy Principle that prescribes how self-organizing biological agents interact with their environment. The study of active inference processes relies on the definition of a generative probabilistic model and a

Importin 7 mediates the nuclear import of HIV‐1 integrase via a specific interacting interface

open access: yesFEBS Open Bio, EarlyView.
HIV‐1 integrase enables viral DNA integration into the host genome. By binding to the core domain of the host protein Importin 7 via its C‐terminal domain, the integrase is transported across the nuclear membrane into the nucleus, where integration of the viral genome into host DNA takes place. This translocation is a critical step for subsequent viral

Hybrid diesel generator/renewable energy system performance modeling

open access: yes, 2014
Published ArticleA Hybrid Energy System may been defined as a system in which different energy sources (solar, wind, hydro, diesel generator, etc.) as well as energy storage systems are interconnected to meet the load energy demand at any time.

The Free Energy Principle and Free Markets

open access: yes
We apply the free energy principle to free markets by treating the Market as a random dynamical system with an attracting set, i.e., some characteristic states.

Optimizing photoexcitation conditions for time‐resolved X‐ray solution scattering experiments

open access: yesFEBS Open Bio, EarlyView.
Time‐resolved X‐ray solution scattering (TR‐XSS) is a powerful technique to visualize how proteins change their structure in real time after light activation. Selecting the right laser photoexcitation conditions—fluence, excitation geometry, and sample refresh rate—is critical to maximize the experimental signal while avoiding unwanted side effects ...

Free riders play fair [PDF]

open access: yes, 2012
After the demise of the social contract theory, the argument from fair play, which employs the principle of fair play, has been widely acknowledged as one of the most promising ways of justifying political obligation.

Morphological Computation: Nothing but Physical Computation

open access: yesEntropy, 2018
The purpose of this paper is to argue against the claim that morphological computation is substantially different from other kinds of physical computation.
