Synthesis of Calcium Sulfate Nanocrystals via Confined Reaction in Ion-Enriched Instantaneous Microdomains

Abstract Hemihydrate calcium sulfate nanocrystals hold promising potential in biomedical and industrial applications. Conventional synthesis methods typically necessitate high temperatures/pressures, acidic/alkaline media, or expensive organic reagents. This study proposes a faci...

Seismic Resilience Evaluation of Double-Pier Bridge Substructures With Delay Time Consideration

Traditional bridges rely on ductile seismic design and hysteretic energy dissipation, followed by repairs to restore service. Double-pier bridge substructures are statically indeterminate; under transverse excitation, pier stresses hinder selecting damage indices, limiting seismi...

The role of LncRNA FOXD3-AS1 in multiple human malignancies

Long non-coding RNA (lncRNA) molecules, which are over 200 nucleotides long without protein-coding potential, play crucial roles in various biological processes and the progression of tumors. Emerging evidence shows that lncRNA forkhead box D3 antisense 1 (FOXD3-AS1) is transcrib...

Three Bets on the Future of Software: Compiler Compiler System AI-Assisted Construction

The conversation about artificial intelligence has narrowed to two competing bets about how human-level capability is built. The first, held by the major frontier labs, is that scaling neural networks produces general intelligence as an emergent property. The second, held by a sm...

AI Limits for the CCS Parsing Model

Could an AI have invented the CCS parsing model from the requirements it satisfies? Five fresh Claude Code sessions, each with no access to the project, were given one 350-word brief stating seven requirements (five-language consumption of one parse output, byte-for-byte regenera...

Compiler Compiler System Translation Pipeline: From Python to TypeScript with Full RealWorld Conformance

Translating an existing application from one general-purpose programming language into another is a long-standing engineering problem with no general solution. Arbitrary source-to-source translation is intractable because the two languages live in different runtime-semantic world...

Compiler Compiler System with Isomorphic Runtime and Binary Structured Intermediate Representations

The Compiler Compiler System (CCS) is a compiler-construction tool that, given a context-free grammar specification, produces a complete compiler for the language that grammar describes. CCS departs from the YACC, GNU Bison, and ANTLR lineage in six specific ways: (i) it replaces...

Multi–analytical investigation of Eastern Han gilded copper coffin ornaments excavated from Wushan, Chongqing, China

Abstract Six Eastern Han Dynasty gilded copper coffin ornaments excavated from Wushan, Chongqing, were analysed by optical microscopy, SEM-EDS, and Raman spectroscopy. Results reveal all samples were gilded with mercury amalgam and gilded layer thicknesses ranged from 0.3 to 8.0...

Identifying Controlling Climate Factors Conducive to Water and Nitrogen Export from an Agricultural Watershed During the Snowmelt Runoff Period Using the SWAT Model

Abstract. Temperature and precipitation variations during the freezing-thawing period affect snowmelt and accompanying nitrogen export in a complex manner. These influences can be long-lasting, superimposed, and strengthened. Daily discharge and nitrate nitrogen NO3--N concentrat...

Material Controls on Landslide-Dam Breach Evolution and Hydrograph Response: A Review

Landslide-dam breaching can generate short-lived, high-magnitude outburst floods, but breach hydrograph prediction remains limited by uncertainty in dam material properties. This review synthesises experimental, field, and modelling evidence through a process chain-linking grain-...

Biological Community and Ecosystem Responses to Dam Removal in a Mountain River

Dam removal is a direct measure to restore river connectivity, but the assessment of its ecological effects has long been constrained by the lack of continuous monitoring data across multiple trophic levels. Based on eight years (2017–2024) of continuous field monitoring data fro...
