How to analyse the performances of innovative variable diffusivity membranes integrated within prefabricated timber facades Compute

open access: yesJournal of Facade Design and Engineering, 2018
Vapour barriers and retarders are often needed to improve the hygro-thermal performance of the building envelope. Their use is particularly important in prefabricated timber façades, especially when critical boundary conditions occur.

Molecular thermal motion harvester for electricity conversion via triboelectrification [PDF]

open access: yesAPL Materials
Molecular thermal motion is ubiquitous, and in theory, the energy of which could be converted into electrical energy. However, not until recently, the conversion of molecular thermal motion into electricity was demonstrated feasible for the first time ...

Message Passing-Based Inference for Time-Varying Autoregressive Models

open access: yesEntropy, 2021
Time-varying autoregressive (TVAR) models are widely used for modeling of non-stationary signals. Unfortunately, online joint adaptation of both states and parameters in these models remains a challenge.

Free Magnetic Energy in Solar Active Regions above the Minimum-Energy Relaxed State [PDF]

open access: yes, 2007
To understand the physics of solar flares, including the local reorganization of the magnetic field and the acceleration of energetic particles, we have first to estimate the free magnetic energy available for such phenomena, which can be converted into ...

Work and Thermal Fluctuations in Crystal Indentation under Deterministic and Stochastic Thermostats: The Role of System–Bath Coupling

open access: yesEntropy, 2022
The Jarzynski equality (JE) was originally derived under the deterministic Hamiltonian formalism, and later, it was demonstrated that stochastic Langevin dynamics also lead to the JE.

On the Decomposition of Free Energies

open access: yesJournal of Molecular Biology, 1996
The decomposition of free energies and entropies into components has recently been discussed within the framework of the free energy perturbation (FEP) and thermodynamic integration (TI) methods. In FEP, the cumulant expansion of the excess free energy contains coupling terms in second and higher orders.

Metastable States of Water Aerosols: Comparison by Experiment

open access: yesAtmosphere, 2021
Free energy of water aerosol plasma was calculated using the Debye–Hückel method. It was established that free energies of droplets, ions and simultaneously of all charged particles had local minima (metastable states) at certain concentrations and ...

Dual-Topology Hamiltonian-Replica-Exchange Overlap Histogramming Method to Calculate Relative Free Energy Difference in Rough Energy Landscape [PDF]

open access: yes, 2006
A novel overlap histogramming method based on Dual-Topology Hamiltonian-Replica-Exchange simulation technique is presented to efficiently calculate relative free energy difference in rough energy landscape, in which multiple conformers coexist and are ...

Partitioning Entropy with Action Mechanics: Predicting Chemical Reaction Rates and Gaseous Equilibria of Reactions of Hydrogen from Molecular Properties

open access: yesEntropy, 2021
Our intention is to provide easy methods for estimating entropy and chemical potentials for gas phase reactions. Clausius’ virial theorem set a basis for relating kinetic energy in a body of independent material particles to its potential energy ...

The Matter of Time

open access: yesEntropy, 2021
About a century ago, in the spirit of ancient atomism, the quantum of light was renamed the photon to suggest that it is the fundamental element of everything. Since the photon carries energy in its period of time, a flux of photons inexorably embodies a
