Propagation of internal gravity waves: Optimal vertical discretisation and grid design based on numerical error analysis

Quarterly Journal of the Royal Meteorological Society, EarlyView.
An energy‐conserving discrete framework for the vertical discretisation of stratified ocean models is developed using internal gravity‐wave theory. A β$$ \beta $$‐indexed family of schemes is analysed through perturbation theory, revealing optimal parameter choices and grid designs that reduce truncation errors significantly.

New Tools for Tuning PID Controllers Using Orthogonal Polynomials

IEEE Access
This paper presents an algorithm to determine PID controller tuning regions that guarantee the stability of closed-loop control systems using the pole placement method, assigning a known robustly stable polynomial that depends on a vector of uncertain ...

Farmers’ Preferences for Sustainable Crop Protection: An Integrated Choice and Latent Variable Approach

Sustainable Development, EarlyView.
ABSTRACT This study analyzes farmers' preferences for sustainable crop protection, focusing on Integrated Pest Management (IPM) practices by incorporating social‐psychological factors to capture economic and behavioral dimensions. Using data from German and Polish potato farmers, we apply an integrated choice and latent variable framework that combines

Three‐Dimensional Optical and Computational Reconstruction of Colloidal Electrokinetic Flows via Multiplane Imaging and Multiscale Modeling

Small, EarlyView.
Fast 3D multiplane microscopy is combined with multiscale electrokinetic modeling to reconstruct nanoparticle motion around quadrupolar electrodes. This integrated optical‐computational framework reveals the full three‐dimensional structure of colloidal electrokinetic flows, including localized trapping, depletion layers, and complex vortical motion ...

Eco‐ductile design of RC columns: Resolving the conflict between embodied carbon and curvature ductility

Structural Concrete, EarlyView.
Abstract Reducing embodied carbon emissions in structural design is of critical importance in combating global climate change. However, the increased material usage and heavy confinement reinforcement required to meet high ductility demands in reinforced concrete columns directly conflict with environmental sustainability goals.

ANPGT: Towards Adaptive Node Property Extraction and Integration

CAAI Transactions on Intelligence Technology, EarlyView.
ABSTRACT Graph transformers (GTs) with elaborate positional/structural encodings (PEs/SEs) have excelled in graph representation learning, especially in graph‐level tasks. However, their potential in large‐scale node classification remains untapped for several reasons: (i) Current PEs/SEs are insufficient in modelling large‐scale real‐world graphs ...

DISCO: a general software tool for dislocation contrast factor calculations in diffraction analysis

Journal of Applied Crystallography, EarlyView.
DISCO is a program capable of calculating the X‐ray contrast factor for single‐ and polycrystalline materials in real time.Dislocation contrast factors (CFs) play a central role in diffraction‐based analyses of plastic deformation, linking the elastic strain fields generated by dislocations to diffraction line broadening.
