Non-equilibrium signal integration in hydrogels

Equilibrium swelling properties of polyampholytic hydrogels

The role of counter ions and ion dissociation in establishing the equilibrium swelling of balanced and unbalanced polyampholytic hydrogels has been investigated experimentally and theoretically. The swelling dependence on both the net charge offset and the external bath salt concentration has been examined using an acrylamide based polyampholytic hydrogels. By careful consideration of the swell...

Targeting Bayes factors with direct-path non-equilibrium thermodynamic integration

Thermodynamic integration (TI) for computing marginal likelihoods is based on an inverse annealing path from the prior to the posterior distribution. In many cases, the resulting estimator suffers from high variability, which particularly stems from the prior regime. When comparing complex models with differences in a comparatively small number of parameters, intrinsic errors from sampling fluc...

Adaptive Energy Integration of Non-Equilibrium Green’s Functions

To obtain the physical quantities of interest within the non-equilibrium Green’s function formalism, numerical integration over energy space is essential. Several adaptive methods have been implemented and tested for their applicability. The number of energy grid points needed and the convergence behavior of the SchrödingerPoisson iteration have been evaluated. An adaptive algorithm based on a ...

Equilibrium swelling, conductivity and electroactive characteristics of polyacrylamide hydrogels

Polyelectrolyte hydrogels are currently being studied extensively towards the realization of soft actuators. The conductivity, swelling behaviour and electroactive characteristics of partially hydrolysed polyacrylamide hydrogels, crosslinked to various extents are investigated. Conductivity studies have been made by means of dielectric relaxation spectroscopy both for hydrogels and dry gel powd...
