Dynamic time-history analysis of prefabricated shear wall structures with unconnected vertical distribution reinforcement

Unconnected vertically distributed reinforcement (SGBL) detailing offers convenient construction and simplified connections; however, the dynamic response and frequency-domain characteristics of the complete structural system under different ground motions remain insufficiently u...

A two-stage efficient fine-tuning framework for vertical domain text embedding

Text embedding in vertical industrial domains provides a critical foundation for professional information retrieval, semantic matching, and intelligent decision-making. However, general-purpose embedding models often fail to meet the demands of complex industrial applications bec...

A 200°C‐Tolerant Water‐Based Drilling Fluid for Ultra‐Deep Wells Using an Organic–Inorganic Multi‐Metal Hydroxide Modifier

ABSTRACT A water‐based drilling‐fluid (WBDF) formulation was developed for moderate‐density ultra‐deep intervals requiring thermal stability at 200°C. The optimized formulation contained 5 wt% APEG/sodium‐citrate‐modified quaternary Mg‐Al‐Fe‐Zn multi‐metal hydroxide (ASMH), 0.3 w...
