Theory of electronic transport in molecular crystals. III. Diffusion coefficient incorporating nonlocal linear eiectron-phonon coupling [PDF]

, 1985
Electronic transport in molecular crystals is studied for simultaneous local and nonlocal linear electron-phonon coupling using a generalized polaron Hamiltonian derived previously.

Multimodal Data‐Driven Microstructure Characterization

Advanced Engineering Materials, EarlyView.
A self‐consistent autonomous workflow for EBSP‐based microstructure segmentation by integrating PCA, GMM clustering, and cNMF with information‐theoretic parameter selection, requiring no user input. An optimal ROI size related to characteristic grain size is identified.

Effects of target configuration on the laser plasma momentum-coupling coefficient [PDF]

, 2006
The plasmas generated in the laser interacting with targets can be used as a new propulsive source. In this paper, the effects of the target configuration on the laser plasma momentum-coupling coefficient are investigated.

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

Advanced 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.

Coupling coefficients of gain-coupled distributed feedback lasers with absorptive grating [PDF]

, 1996
An effective coupling efficient is introduced for gain-coupled distributed feedback lasers with absorptive grating. When radiation and other partial wave coupling effects are considered, the effective coupling coefficient will change significantly.

Creep‐Induced Microstructural Evolution in an A2‐B2 Superalloy

Advanced Engineering Materials, EarlyView.
A 27.3Ta‐27.3Mo‐27.3Ti‐8Cr‐10Al (at.%) refractory high‐entropy alloy with precipitation‐strengthened A2‐B2 microstructure was studied by creep tests at 1030°C, which demonstrate a transition in deformation mechanisms in the range of 100–150 MPa applied stress. This is associated with changes in dislocation–precipitate interactions. Relevant deformation
