Twist Free Energy

open access: yesThe European Physical Journal B, 2001
One may impose to a system with spontaneous broken symmetry, boundary conditions which correspond to different pure states at two ends of a sample.

Rényi Entropy and Free Energy

open access: yesEntropy, 2022
The Rényi entropy is a generalization of the usual concept of entropy which depends on a parameter q. In fact, Rényi entropy is closely related to free energy. Suppose we start with a system in thermal equilibrium and then suddenly divide the temperature

From free-energy profiles to activation free energies

open access: yesThe Journal of Chemical Physics, 2022
Given a chemical reaction going from reactant (R) to the product (P) on a potential energy surface (PES) and a collective variable (CV) discriminating between R and P, we define the free-energy profile (FEP) as the logarithm of the marginal Boltzmann distribution of the CV. This FEP is not a true free energy. Nevertheless, it is common to treat the FEP

Molecular thermal motion harvester for electricity conversion

open access: yesAPL Materials, 2023
Molecular thermal motion has been studied but yet never been utilized as an energy source. In this work, we demonstrate that the energy of liquid molecular thermal motion can be converted into electrical energy by a novel harvesting device, the molecular

Free energy and defect C-theorem in free fermion

open access: yesJournal of High Energy Physics, 2021
We describe a p-dimensional conformal defect of a free Dirac fermion on a d-dimensional flat space as boundary conditions on a conformally equivalent space ℍ p+1 × S $$ \mathbbm{S} $$ d−p−1.

Psychophysical identity and free energy [PDF]

open access: yes, 2020
An approach to implementing variational Bayesian inference in biological systems is considered, under which the thermodynamic free energy of a system directly encodes its variational free energy.

Free energy and defect C-theorem in free scalar theory

open access: yesJournal of High Energy Physics, 2021
We describe conformal defects of p dimensions in a free scalar theory on a d-dimensional flat space as boundary conditions on the conformally flat space ℍ p+1 × 𝕊 d−p−1.

Head-to-head comparison of ultrasound and 99mTc-glucosamine SPECT/CT imaging of patients with rheumatoid arthritis: a single center prospective study

open access: yesThe Egyptian Journal of Radiology and Nuclear Medicine, 2023
Background Rheumatoid arthritis (RA) is an inflammatory disease that can lead to progressive joint damage. Early identification of synovitis is key in the management of patients with RA.
