Supplementary Software S1: Three-dimensional model of coupled heat and moisture transfer, grain respiration and insect population dynamics in aerated wheat storage

Python/NumPy/SciPy implementation of the three-dimensional cell-centred finite-volume model described in the article "Three-Dimensional Modelling of Coupled Heat and Moisture Transfer, Grain Respiration and Insect Population Dynamics in Aerated Wheat Storage: Continuous versus Controlled Aeration" (Kurbonov, Shadmanov,...

Repetitive negative thinking is associated with conflict-related neural activity that modulates evidence accumulation.

Repetitive negative thinking (RNT), including worry and rumination, is a transdiagnostic feature of anxiety and depressive disorders and is linked to altered cognitive control. However, the decision-level mechanisms underlying these alterations are not well understood. Here, we examined whether individual variation in...

Effect of Azadirachta indica Paste on Lactobacillus rhamnosus in Dentinal Tubules and Its Cytotoxicity for Dental Pulp Stem Cells

Objectives: Azadirachta indica var. siamensis Valeton, also known as neem, possesses various beneficial biological properties, including antibacterial activity. Neem paste (NZ-paste) was developed to enhance its application. This study aimed to investigate the antibacterial activity of NZ-paste against Lactobacillus rh...

Modeling fracture grouting diffusion of cementitious rapid-setting grouts with continuous time-dependent viscosity and phase evolution

From Electronic Heterogeneity to Extreme Residence Times: A Multiscale Model of Energetic Stabilization, Stochastic Trapping, and Transport

Persistent local states can arise without a uniform reduction in system-wide mobility.Here, we develop a minimal multiscale model to examine whether mi-croscopic electronic heterogeneity can propagate through energetic stabi-lization into extreme local residence-time statistics.A four-state effective Hamiltonian was us...

Prediction of Structural Defects During Solidification of Al-Si-Mg Alloy System by Scheil-Gulliver Method

This study applies Scheil-Gulliver non-equilibrium solidification modeling, implemented in ProCAST 13.5.2 with the AlDATA 4.2 thermodynamic database, to predict defect-promoting intermetallic phase formation in an AlSi9Mg alloy (Si 9.2, Mg 0.45, Ni 0.19, Fe 0.2, Mn 0.3 wt.%) derived from automotive scrap remelting in C...

Replication Data and Python Code for: Pathwise Concentration in Regime-Switching Fractional Diffusions

This repository contains the S&P 500 dataset (n=4{,}211 daily logarithmic returns) and Python code used to empirically motivate the regime-switching framework in the associated manuscript. The code implements the scaled forward--backward EM algorithm to fit a two-state Gaussian hidden Markov model, generating maximum l...

Engineering Spatially Localized Bioactive Microenvironments in Assembly Implants for Spatially Extended Bone Ingrowth

ABSTRACT The repair of large segmental bone defects requires implants that combine structural stabilization with biological regulation. Here, we developed a bioadaptive modular implant integrating porous titanium (Ti) alloy for structural reinforcement with spatially localized β‐tricalcium phosphate (β‐TCP) modules for...

Generating Structural Ensembles of Disordered Proteins with Diffusion Models

Generative models of protein structures have accelerated scientific discovery. However, the leading structure-prediction models are trained primarily on crystal structures, limiting their ability to sample the conformations of intrinsically disordered proteins (IDPs). All-atom molecular dynamics (MD) simulations can pr...

TransWeld: automated radiographic inspection and defect analysis framework for pressure-vessel welds

Radiographic inspection automation and defect analysis for industrial non-destructive testing (NDT) are introduced here for the first time. It uses transformer-based global encoding with convolutional local feature extraction to better identify small and low-contrast defects under varying illumination and noise conditi...

Multiparameter analysis of the persistence-extinction thresholds in benthic-drift patch models

In this paper, we investigate the global dynamics of the benthic-drift patch model, in which individuals in the benthic zone remain stationary while those in the drift zone undergo diffusion and advection with the water flow. We establish threshold dynamics via the principal eigenvalue of the linearized system at the z...
