A one-step flow matching model using transformer in VAE latent space with non-Gaussian source and auxiliary networks generates accurate high-resolution path-dependent stress fields, achieving 6-7x CPU and ~100x GPU speedup over FEM.
Develops and calibrates an anisotropic hyperelastic constitutive model based on octahedral fiber networks for mitral valve leaflets to examine effects of anisotropy and reorientation on closure and mitral regurgitation.
Anharmonic calculations show random CoCrNi ISFE decreases and stays negative with temperature while LCO ISFE stays positive from 0-1000 K, with MD confirming unbounded vs finite dislocation dissociation.
YbN thin films are insulating with a 1.7 eV band gap, showing LO and TO phonon modes plus a defect-induced absorption tail indicating the Fermi level lies in a disordered conduction band minimum.
The zentropy approach receives a statistical-physics foundation via recursive entropy maximization, yielding partition functions for coarse-grained configurations and clarifying temperature-dependent states in thermodynamic systems.
Mask-conditioned LDM generates synthetic TEM defect image-mask pairs that augment small experimental sets and produce up to 0.02 gain in harmonic-mean F1 for combined detection and classification with Mask R-CNN.
Autoencoders plus PCA compress microstructural images from phase-field simulations by a factor of 196 while retaining over 80 percent accuracy, and LSTM networks then predict subsequent frames to speed up the simulations.
