The Awareness-First Theory: A Coherence Principle Underlying Active Inference and Physical Law [PDF]
EntropyThe Free Energy Principle (FEP) and Active Inference provide a unifying variational framework for modelling perception, action, learning, and self-organisation across biological systems.

Carnot and Joule Cycles Implied in Generalized Entropy and Exergy Properties as Fundamentals of Extrema Principles [PDF]
EntropyThermodynamic laws and principles overarch all domains of physics, chemistry and biology. In this broad perspective, further generalizations with respect to the “state-of-the-art” of current theories are still viable considering all aspects of systems ...

Linear bosonic quantum field theories arising from causal variational principles [PDF]
Letters in Mathematical Physics, 2022 It is shown that the linearized fields of causal variational principles give rise to linear bosonic quantum field theories. The properties of these field theories are studied and compared with the axioms of local quantum physics. Distinguished quasi-free

Quantum medicine: A quantum–mechanical framework for redox biology, disease and precision medicine [PDF]
Clinical and Translational MedicineBackground Key biological processes underlying health and disease‐including electron transfer, redox regulation, and radical‐mediated signaling‐are fundamentally governed by quantum‐mechanical principles.

Fluids, 2022 In this paper, we discuss some well-known experimental observations on self-organization in dissipative systems. The examples range from pure fluid flow, pattern selection in fluid–solid systems to chemical-reaction-induced flocking and aggregation in ...

First principles of consistent physics
, 2021 For a consistent picture of fundamental physics and cosmology, three first principles are proposed as the foundations. That is, quantum variational principle that provides the formalism, consistent observation principle that set physical constraints and ...

Existence Solution for a Non-smooth System [PDF]
Mathematics Interdisciplinary ResearchA variational method for a mixed boundary value problem in mathematical physics is considered. Using two-field Lagrange multipliers, we would investigate a variational formulation containing a mixed variational problem which is equivalent with a ...
