Exact Toda black holes of rank-2 Lie groups
A bstract We consider Einstein gravity coupled to two Maxwell fields and one dilatonic scalar, and construct spherically-symmetric and static black holes that are charged under both Maxwell fields in general D dimensions. We find that for suitable dilaton couplings, the equations...

Multi-Objective Optimization and Global Design for Active Magnetic Dry Friction Damper Actuators
To address the tradeoff among high force, fast response, and compact volume in active magnetic dry friction dampers, this paper proposes a systematic multi-objective optimization framework centered on an interpretable global design surface. A parametric analytical model mapping t...

Not All Praise Is Equal: How AI Shopping Assistants' Praise Target Shapes Consumer Behavior
ABSTRACT Generative AI has led many e‐commerce firms to adopt AI shopping assistants that advise consumers much as human salespeople do. In offline retail, salespeople often praise either the consumer or the product to encourage a purchase. Although praise is among the most commo...

Experimental investigation of the direct shear strength parameters of compacted snow
Abstract. Compacted snow is utilized as a building material in various construction and engineering applications across global high-latitude regions. For the safety assessment of snow and ice structures in cold regions, cohesion and internal friction angle are key shear strength...

Seasonaland Habitat-Specific Mercury Cycling in CoastalBiota Revealed by Species-Specific Isotopes
Abstract Understanding how inorganic mercury (IHg, primarily Hg(II)) and methylmercury (MeHg, primarily monomethylmercury) transform and cycle in coastal food webs is essential for evaluating Hg exposure risks, yet relevant species-specific mercury (Hg) isotope studies remain sca...

Runoff Simulation and Analysis in the Upper Yellow River Basin Using a Budyko–XGBoost Coupled Model
The Upper Yellow River (UYR) basin is the predominant runoff-yielding area of the entire watershed. Accurately simulating annual runoff is crucial for water resources management. While the Budyko framework effectively captures long-term hydro-thermal equilibrium, it struggles to...
