Attention‐Based Spatial–Temporal Model for the Entire Indoor Space Temperature Estimation
IEEJ Transactions on Electrical and Electronic Engineering, EarlyView.This study proposes a novel attention‐based spatial–temporal model for indoor temperature estimation, which integrates positional encoding and an attention mechanism with a fully connected neural network. By jointly capturing temporal dynamics and spatial correlations, the model enables high‐resolution estimation of temperature fields across the entire

Tubes or Ribbons? Comparing Texture‐space Visualization for Multivariate Line Data
Computer Graphics Forum, EarlyView.Abstract Multivariate line data is critical for analyzing flow fields, agent systems, and dynamic trajectories. Embedding secondary variables along spatial paths using surface‐based primitives such as ribbons and circular tubes introduces challenges related to perspective, scale, and distortion.

Reactive Mixing Fronts in Porous Media Under Transverse Velocity Gradients
Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.Abstract Mixing‐limited reactions in porous media depend on concentration gradients at interfaces, yet their behavior in nonuniform co‐flow remains poorly understood. Here we develop a closed‐form theory for irreversible reactions A+B→P $A+B\to P$ in a co‐flow where a transverse velocity gradient makes transverse hydrodynamic dispersion vary linearly ...

Intrusive Polynomial Chaos for CFD Using OpenFOAM [PDF]
, 2020 We present the formulation and implementation of a stochastic Computational Fluid Dynamics (CFD) solver based on the widely used finite volume library - OpenFOAM. The solver employs Generalized Polynomial Chaos (gPC) expansion to (a) quantify the uncertainties associated with the fluid flow simulations, and (b) study the non-linear propagation of these

Mixing‐Driven Defects and Composition Evolution in Multi‐Material Metal Additive Manufacturing
Advanced Science, Volume 13, Issue 45, 13 August 2026.Operando synchrotron X‐ray imaging coupled with high‐fidelity multiphysics modeling uncovers how inter‐material mixing reshapes keyhole dynamics and drives distinct pore‐formation pathways in multi‐material laser powder bed fusion (LPBF). Composition‐dependent instabilities trigger defects, whereas rescanning suppresses porosity and homogenizes Cu ...

Journal of Geophysical Research: Oceans, Volume 131, Issue 8, August 2026.Abstract Volcanic islands are prone to flank instabilities that can generate tsunamis even when mobilized volumes are moderate. This study investigates submarine collapses during the 2011–2012 eruption south of El Hierro, which built the Tagoro submarine volcano.
