Computational advances and challenges in simulations of turbulence and star formation

Abstract We review recent advances in the numerical modeling of turbulent flows and star formation. An overview of the most widely used simulation codes and their core capabilities is provided. We then examine methods for achieving the highest-resolution magnetohydrodynamical turbulence simulations to date, highlightin...

Finite-element-assisted interpretable graph attention learning for high-fidelity prediction of mass transport in fibrin biomaterials

Abstract Accurate prediction of spatial concentration fields within biomaterials is important for mass-transfer analysis and computational modeling of transport processes. This study develops an interpretable data-driven framework for spatially resolved mass-transport prediction by coupling finite element mass-transfer...

A comparative analysis of graph neural networks through similarity-based information propagation across diverse network structures

Abstract Information propagation over graph-structured data depends critically on the quality of node representations learned by graph neural networks (GNNs). However, how different GNN architectures organize embedding spaces and how these representations influence downstream propagation behavior remain insufficiently...

A Fine-Grained Image Dataset of Gold and Silver Artifacts from the Tomb of Prince Liangzhuang and Preliminary LoRA-Based Generation Experiments

The digital preservation of cultural heritage is evolving from static archiving towards intelligent creation. As representative examples of early Ming Dynasty gold and silver craftsmanship, the gold and silver artifacts from the Tomb of Prince Liangzhuang, with their complex craftsmanship and rich cultural significance...

A Model Coupled with Fractional-Derivative and Peridynamic Theory for Water Migration in Unsaturated Expansive Clay

Expansive clay exhibits multiple fissures and undergoes deterioration due to fluctuations in moisture levels. To guarantee the stability of earth structures built on expansive clay in semiarid regions, significant emphasis has been placed on studying the effects of water migration. This paper introduces an innovative...

Local coordination and migration-network topology shape Li-ion transport and delithiation in the low-energy ɛ-LiMnO2 polymorph

In rocksalt-derived oxide cathodes, the local Li-migration environment around an O 4 tetrahedral intermediate is commonly classified by the number of face-sharing transition-metal (TM) neighbors. In LiMnO 2 , the TM species is Mn, and 0-TM denotes the absence of face-sharing Mn neighbors. However, migration and delithi...

ST-Policy: Encoding Spatiotemporal Continuity for Diffusion Policy

Diffusion-based visuomotor policies are a powerful paradigm for robotic imitation learning, yet their sequence models apply a uniform inductive bias at every position of the action sequence, ignoring the spatiotemporal continuity inherent in robotic motion. We identify a fundamental limitation of causal state space mod...

DiffMove: Group Mobility Tendency Enhanced Trajectory Recovery via Diffusion Model

This work proposes a novel method called DiffMove that harnesses crowd wisdom for trajectory recovery and integrates group mobility tendencies and individual preferences into the spatiotemporal distribution of the trajectory to recover high-quality trajectories.

Generative AI Model Assisted Multimodal Semantic Vehicular Edge Computing for Collaborative Perception

Vehicular edge computing (VEC) plays a pivotal role in enabling cooperative perception for connected autonomous vehicles (CAVs), providing comprehensive environmental awareness for safe vehicle control and road safety. However, collaborative perception in VEC faces significant challenges arising from stringent bandwidt...

Generative Data-Augmented Surrogate Modelling Framework for Field Quality Improvement in ReBCO Bulk Undulators Under Limited Data Constraints

Abstract High-temperature superconducting (HTS) bulk staggered-array undulators can generate record-breaking magnetic fields for compact light sources, but their performance is limited by non-uniform magnetic field profiles. This spatial inhomogeneity is directly related to variations in the critical current density am...

An extended Taylor–Aris Framework for Thermal Front Propagation in Conjugate Pipe Flows: The Plug-Flow Limit

A reduced one-dimensional unsteady description of thermal-front propagation in conjugate pipe flows is developed here for the plug-flow limit. The starting point is the analytical advection–diffusion solution for an adiabatic fluid domain, with its characteristic exponential–error-function form. The plug-flow assumptio...
