In this work, a progressive failure analysis framework is proposed to investigate the bending failure mechanisms of composite sandwich beams with syntactic foam cores. The numerical framework incorporates the cohesive zone model to simulate interface debonding and adopts Hashin's...

Topology‐Dependent Iso ‐Propanol Dehydration Pathway Over Zeolites

ABSTRACT The zeolite‐catalyzed dehydration of low‐carbon alcohols is a crucial step in the conversion of biomass‐derived compounds. Compared to methanol and ethanol, the propanol dehydration mechanism remains poorly understood. The core challenge lies in the high reactivity and s...

Diagnosing urban flood resilience and built-environment adaptation priorities in Henan Province, China

Purpose This study develops a multi-criteria framework to assess relative urban flood resilience, temporal change and built-environment adaptation constraints across 18 municipal-level units in Henan Province, China. Design/methodology/approach Seventeen indicators covering natur...

Hi-SCCG: Hierarchical Structure-aware Chunking and Context Generation for document-level information extraction

Large Language Model (LLM)-based generative Information Extraction (IE) over long documents is constrained by finite context windows, and the necessary text-chunking step disrupts semantic continuity, causing subject drift, unresolved coreference, and loss of the global constrain...

An interpretable large language model framework with the cokemaking-oriented prompt and fuzzy-enhanced explanation for coke quality prediction

Although many data-driven coke quality prediction models have been proposed, existing approaches primarily rely on structured data and fail to effectively utilize the large amount of accumulated domain knowledge, such as published technical reports and scientific literature in th...

A hierarchical spatio-temporal reinforcement learning framework for cooperative multi-USV search and interception

Multi-USV cooperative search and target interception holds value in maritime security, yet existing methods face three challenges: multi-timescale decision coupling, insufficient heterogeneous observation fusion, and inefficient exploration under sparse rewards. This paper propos...

HAC-NET: A soft displacement estimation network for digital image correlation

Digital image correlation (DIC) plays an important role in full-field deformation analysis. However, existing methods suffer from insufficient accuracy because hard matching mechanisms fail to fully exploit the matching information in correlation volumes. Additionally, the limite...

Amine-rich cross-linking templates enabling toughened self-assembled monolayer for stable perovskite solar modules

As the most popular hole-selective materials in efficient p-i-n perovskite solar cells (PSCs), self-assembled monolayers (SAMs) still remain great challenges in long-term stability due to their frail construction and week bonding. To form a toughened donor-acceptor interface, her...

Bioinspired topology-physical-field co-driven design of multi-morphology TPMS lattices for load-bearing and thermal insulation

The trade-off between load-bearing capacity and thermal insulation limits lightweight multifunctional structures requiring both mechanical support and thermal protection. Inspired by the three-layer architecture of pomelo peel, this study proposes a bioinspired topology-physical-...
