Multiscale Analysis of Amine‐Containing CO2 Capture Membrane via Dissipative Particle Dynamics Simulations Using Ab Initio Elongation Method‐Based Parameters

Carbon Energy, EarlyView.
Elongation (ELG) method for calculating the electronic structures of aperiodic polymers was combined with dissipative particle dynamics (DPD) simulation to perform more reliable simulations using quantum chemistry (QC)‐based parameters. The method was employed to analyze phase separation in an amine‐containing CO2 capture membrane, and the results ...

Amino Acid and Biogenic Amine Profiles in Sausages Reformulated With Processed, Fermented Oyster Mushrooms

ChemFoodChem, EarlyView.
This research showed that sausage reformulation preserves high essential amino acid and branched‐chain amino acid content, as well as increasing free amino acids (FAA) related to umami flavor and health‐promoting components such as GABA in the products.

Accelerating SCF Convergence Through Equivariant Density‐Matrix Learning and Analytic Refinement

Chemistry – A European Journal, EarlyView.
Machine learning predicts physically consistent one‐electron reduced density matrices that provide efficient initial guesses for self‐consistent field calculations. Across diverse molecular systems, this warm‐start strategy reduces the required self‐consistent‐field (SCF) iterations by up to 80% while preserving converged energies and atomic forces ...

Accelerating Frequency Response Measurements Through Sparse Data‐Driven Reconstruction Using the Loewner Framework

Chemie Ingenieur Technik, EarlyView.
Frequency response analysis is vital for electrochemical diagnostics but inherently time‐consuming. By building state‐space models from sparse frequency samples, the Loewner framework accurately reconstructs transfer functions and distribution of relaxation times (DRT), drastically cutting testing time without sacrificing accuracy.

Dynamic survival risk prediction with time‐varying high‐dimensional images

Canadian Journal of Statistics, EarlyView.
Abstract Integrating longitudinal data with survival models is a prevalent strategy for dynamic survival risk prediction while accounting for subjects' longitudinally observed variables. However, existing methods primarily focus on scalar longitudinal data and seldom tackle the complexities associated with high‐dimensional longitudinal imaging data ...

A Method for Finding LR Fuzzy Eigenvectors of Real Symmetric Matrix

Transactions on Fuzzy Sets and Systems
In this paper, the calculation methods of the real eigenvalues and LR fuzzy eigenvectors of clear real symmetry matrices are deeply considered. The original fuzzy feature problem is extended by using the arithmetic algorithm of LR fuzzy numbers into a ...

Learning sparse mixture‐of‐experts generalized linear models in ultrahigh dimensions

Canadian Journal of Statistics, EarlyView.
Abstract Motivated by the challenges of heterogeneity and high dimensionality in the analysis of modern data, we investigate continuous regularization methods for learning sparse mixture‐of‐experts generalized linear models (MoE‐GLM). Although there are foundational results about regularized estimators in a broad class of regression models including ...

Front Propagation Through a Perforated Wall

Communications on Pure and Applied Mathematics, EarlyView.
ABSTRACT We consider a bistable reaction– diffusion equation ut=Δu+f(u)$u_t=\Delta u +f(u)$ on RN${\mathbb {R}}^N$ in the presence of an obstacle K$K$, which is a wall of infinite span with many holes. More precisely, K$K$ is a closed subset of RN${\mathbb {R}}^N$ with smooth boundary such that its projection onto the x1$x_1$‐axis is bounded and that ...
