Symbolic Regression and Multi‐Objective Optimization of the Flory–Huggins Interaction Parameter for Hydrogels

open access: yesAdvanced Engineering Materials, EarlyView.
We develop a data‐driven method to derive the mathematical expressions of the Flory–Huggins interaction parameter χ for the swelling behavior of temperature–responsive hydrogels. Starting from initial assumptions of χ, our workflow combines Bayesian optimization, Flory–Rehner theory, and symbolic regression to generate candidate χ expressions.

Optimization of the Production of Rubber Compounds Using Mathematical Models

open access: yesAdvanced Engineering Materials, EarlyView.
Rubber compounds were mixed in a batch internal mixer, and symbolic regression was used to derive mathematical models linking recipe and process parameters to ram path, torque, and mixing quality (incorporation, dispersion, distribution). Subsequent optimization with evolutionary algorithms identified operating conditions that reduce specific energy ...

The trace of the trace of the energy–momentum tensor-dependent Einstein’s field equations

open access: yesEuropean Physical Journal C: Particles and Fields, 2019
The f(R, T) gravity field equations depend generically on both the Ricci scalar R and trace of the energy–momentum tensor T. Within the assumption of perfect fluids, the theory carries an arbitrariness regarding the choice of the matter lagrangian ...

Law, Arbitrariness and Ethics [PDF]

open access: yesCalifornia Law Review, 1942
aminations, from various points of view, of a series of interconnected issues: the essential nature of constitutional government, the function of force in political affairs, the proper sphere of governmental authority, the necessity and limits of discretion, the sphere of reason in politics, the basis and applicability of an adequate political ethics ...

Workflow for Design of Experiments‐Based Modeling of Species Transport and Growth Kinetics in GaN Hydride Vapor Phase Epitaxy

open access: yesAdvanced Engineering Materials, EarlyView.
A novel workflow for investigating hydride vapor phase epitaxy for GaN bulk crystal growth is proposed. It combines Design of experiments (DoE) with physical simulations of mass transport and crystal growth kinetics, serving as an intermediate step between DoE and experiments.

Color Categories Are Not Arbitrary [PDF]

open access: yesCross-Cultural Research, 2002
Recent, well-controlled studies in cross-language color naming and cross-language tests of color memory and learning have made important contributions to our understanding of which aspects of cross-language color naming and nonverbal response to colors may and may not be attributed to pan-human properties of color appearance.

Molecular Dynamics Studies of Shape Memory Polymers: From Bead–Spring Models to Atomistic Simulations

open access: yesAdvanced Engineering Materials, EarlyView.
Coarse‐grained (left) and atomistic (right) models of the shape memory polymer ESTANE ETE 75DT3 are shown schematically. The two representations bridge molecular detail and mesoscopic description. Both models capture shape memory behavior, linking segmental mobility and conformational relaxation of anisotropic chains to macroscopic recovery, and ...

BOSONIZATION IN ARBITRARY GENUS

open access: yesPhysics Letters B, 1986
The equivalence is proved between fermionic and scalar field theories on Riemann surfaces of arbitrary topology. The effects of global topology include a modification of the bosonic action.
