The Effect of the Protein Synthesis Entropy Reduction on the Cell Size Regulation and Division Size of Unicellular Organisms

open access: yesEntropy, 2022
The underlying mechanism determining the size of a particular cell is one of the fundamental unknowns in cell biology. Here, using a new approach that could be used for most of unicellular species, we show that the protein synthesis and cell size are ...

Entropy Pair Functional Theory: Direct Entropy Evaluation Spanning Phase Transitions

open access: yesEntropy, 2021
We prove that, within the class of pair potential Hamiltonians, the excess entropy is a universal, temperature-independent functional of the density and pair correlation function. This result extends Henderson’s theorem, which states that the free energy

Thermodynamic Integration in 3n Dimensions Without Biases or Alchemy for Protein Interactions

open access: yesFrontiers in Physics, 2020
Thermodynamic integration (TI), a powerful formalism for computing Gibbs free energy, has been implemented for many biophysical processes with alchemical schemes that require delicate human efforts to choose/design biasing potentials for sampling the ...

Inquiries into the Nature of Free Energy and Entropy in Respect to Biochemical Thermodynamics [PDF]

open access: yes, 2000
Free energy and entropy are examined in detail from the standpoint of classical thermodynamics. The approach is logically based on the fact that thermodynamic work is mediated by thermal energy through the tendency for nonthermal energy to convert ...

Sampling Free Energy Surfaces as Slices by Combining Umbrella Sampling and Metadynamics [PDF]

open access: yes, 2016
Metadynamics (MTD) is a very powerful technique to sample high-dimensional free energy landscapes, and due to its self-guiding property, the method has been successful in studying complex reactions and conformational changes.

Targeted free energy perturbation

open access: yes, 2001
A generalization of the free energy perturbation identity is derived, and a computational strategy based on this result is presented. A simple example illustrates the efficiency gains that can be achieved with this method.Comment: 8 pages + 1 color ...

Cluster expansion for the description of condensed state: crystalline cell approach

open access: yesCondensed Matter Physics, 2018
A well-known cluster expansion, which leads to virial expansion for the free energy of low density systems, is modified in such a way that it becomes applicable to the description of condensed state of matter.

Molecular simulation of rapid translocation of cholesterol, diacylglycerol, and ceramide in model raft and nonraft membranes

open access: yesJournal of Lipid Research, 2012
The translocation of lipids across membranes (flip-flop) is an important biological process. Slow exchange on a physiological timescale allows the creation of asymmetric distributions of lipids across cellular membranes.

Free Energy of ABJM Theory

open access: yes, 2011
The free energy of ABJM theory has previously been computed in the strong and weak coupling limits. In this note, we report on results for the computation of the first non-vanishing quantum correction to the free energy, from the field theory side.

Two-loop HTL Thermodynamics with Quarks [PDF]

open access: yes, 2003
We calculate the quark contribution to the free energy of a hot quark-gluon plasma to two-loop order using hard-thermal-loop (HTL) perturbation theory.
