Abstract The mechanism of the reinforcement of rubber by carbon black has until recently been interpreted from the physical point of view. According to the researches of P. A. Rebinder and coworkers the extent of the interaction between the filler and the rubber is given by the decrease in the free energy of the system resulting from the wetting of 1 cm2 of the surface of the filler particles by rubber. The rubber is bound to the surface of the carbon black particles through adsorption and forms around these particles an extended film which is characterized by high strength; in this state the rubber is referred to as “bound” or film-like rubber. In systems in which such adsorbed rubber is present there appears on the surface of the filler particles an effect which resembles a kind of “crystallization” of rubber which results in a strengthening of the interaction between individual chains and hence in increased strength of the rubber. According to Kusov, at optimum filling of the rubber with carbon black the mixture constitutes a continuous mass—a molecular space lattice with carbon particles situated in its nodes.

Polyakov Loops

Polyakov loops [Formula: see text], [Formula: see text] are shown to give the most important non-perturbative (np) contribution to the thermodynamic potentials. Derived from the gluonic field correlators (FCs), they enter as factors into free energy. It is shown in the SU(3) case that [Formula: see text] define to a large extent the behavior of the free energy and the trace anomaly [Formula: see text], most sensitive to np effects.

ABSTRACTBiological molecular machines are enzymes that simultaneously catalyze two processes, one donating free energy and second accepting it. Recent studies show that most native protein enzymes have a rich stochastic dynamics of conformational transitions which often manifests in fluctuating rates of the catalyzed processes and the presence of short-term memory resulting from the preference of certain conformations. For arbitrarily complex stochastic dynamics of protein machines, we proved the generalized fluctuation theorem predicting the possibility of reducing free energy dissipation at the expense of creating some information stored in memory. That this may be the case has been shown by interpreting results of computer simulations for a complex model network of stochastic transitions. The subject of the analysis was the time course of the catalyzed processes expressed by sequences of jumps at random moments of time. Since similar signals can be registered in the observation of real systems, all theses of the paper are open to experimental verification.STATEMENT OF SIGNIFICANCEThe transient utilization of memory for storing information turns out to be crucial for the movement of protein motors and the reason for most protein machines to operate as dimers or higher organized assemblies. From a broader physical point of view, the division of free energy into the operation and organization energies is worth emphasizing. Information can be assigned a physical meaning of a change in the value of both these functions of state.

Abstract There are serious theoretical problems with the free-energy principle model, which are shown in the current article. We discuss the proposed model's inability to account for culturally emergent normativities, and point out the foundational issues that we claim this inability stems from.
