Composition Dependent Dynamic Behaviors of Non‐Stoichiometric Cocrystalline Hydrogen‐Bonded Organic Frameworks

open access: yesSmall, Volume 21, Issue 49, December 10, 2025.
Composition‐dependent dynamic transformation of non‐stoichiometric cocrystalline hydrogen‐bonded organic frameworks (NS‐HOFs) composed of tetrakis(4‐carboxyphenyl)hexahydropyrene and ‐pyrene derivatives is achieved. The transformation speed is not proportional to the composition ratio, while the maximum speed was observed for the 1:1 mixed HOF ...

PURR - The Persistent URL Resource Resolver [PDF]

open access: yes, 2001
URLs have a precarious functional lifespan. They resolve the intended target (web page, PDF, audio stream, and so on) only so long as the target is available, otherwise they'll point to a dead end.

Using Fuzzy Linguistic Representations to Provide Explanatory Semantics for Data Warehouses [PDF]

open access: yes, 2003
A data warehouse integrates large amounts of extracted and summarized data from multiple sources for direct querying and analysis. While it provides decision makers with easy access to such historical and aggregate data, the real meaning of the data has ...

Effectiveness of Influenza Vaccines and Duration of Protection Against Hospitalisation in England: 2022/2023 and 2023/2024 Seasons

open access: yesInfluenza and Other Respiratory Viruses, Volume 19, Issue 12, December 2025.
ABSTRACT Background Linkage of national, healthcare data can provide greater resolution of vaccine effectiveness (VE) against influenza subtypes, as well as the relative effectiveness of different vaccine types and the effects of waning on VE. We present 2022/2023 and 2023/2024 end‐of‐season VE against hospitalisation with laboratory confirmed ...

Ontology‐driven intelligent assessment system for dam structural safety based on spatiotemporal anomaly detection framework

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 29, Page 5649-5671, 9 December 2025.
Abstract Dam safety assessment systems play a pivotal role in evaluating the structural integrity of critical hydraulic infrastructures. Current implementations frequently exhibit limitations in critical functionalities including multi‐source data integration and automated anomaly detection.

Desolvation‐Induced Network Reformation and Cracking in the Single Crystals of Hydrogen‐Bonded Frameworks Composed of Tetraazaanthraquinone and Anthraquinone Derivatives

open access: yesAngewandte Chemie, Volume 137, Issue 33, August 11, 2025.
Two solvated hydrogen‐bonded organic frameworks (HOFs) based on tetraazaanthraquinone and anthraquinone were found to undergo quasi single‐crystal‐to‐single‐crystal transformations through hydrogen‐bond cleavage and re‐formation. These transformations induced crystal crack propagations, and molecular‐level correlations between the structural ...

Hydrogen Bond Reformation in Tetracarboxylic Acid‐Based Organic Frameworks with Square Lattice Topology

open access: yesChemistry – A European Journal, Volume 31, Issue 64, November 17, 2025.
Structural transformation in hydrogen‐bonded organic frameworks (HOFs) via bond cleavage and reformation is highlighted. Sql‐type HOFs composed of tetracarboxylic acids bearing 4,4′‐dicarboxy‐o‐terphenyl moieties are shown to be particularly prone to H‐bond reformations.
