ABSTRACT Continuous generalization is a key technique for achieving continuous scale representation of map features, and the continuous merging of buildings is a crucial component of this process. Existing methods for continuous building merging predominantly focus on smooth geom...

Hopf bifurcation in a reaction-diffusion system with mixed instantaneous and nonlocal delayed density dependence

This paper considers a generalized Lotka-Volterra reaction-diffusion population system with mixed instantaneous and nonlocal delayed density dependence and subject to homogeneous Dirichlet boundary conditions. The existence and asymptotic expression of the positive steady-state b...

Spatial-Morphological Optimization of Outdoor Wind Environments in Cold-Region Valley Residential Areas for Sustainable Urban Development: Based on the OED-AHP Coupled Framework

Constrained by the dual effects of terrain-induced funneling and continental climate, the outdoor wind environment of residential areas in cold-region valley cities faces an inherent contradiction between winter wind shielding and basic ventilation. Existing studies predominantly...

Cold-adapted membrane-aerated biofilm reactor for domestic wastewater treatment in northwest China: Pollutant removal performance and mechanistic insights

Membrane-aerated biofilm reactors (MABRs) have considerable potential for carbon and nitrogen removal from domestic wastewater. However, their long-term performance under high-altitude, low-temperature, and low-C/N conditions remains insufficiently understood. In this study, a pi...

Interpretable Causal Structure Learning for Multivariate Air Quality Forecasting: An Integrated Evolutionary-Cognitive Approach

Accurate Air Quality Index (AQI) forecasting is essential for public health protection and sustainable urban planning. Existing data-driven forecasting models often provide limited interpretability of pollutant interactions, while conventional Fuzzy Cognitive Map (FCM) learning a...

Facile Enhancement of Corrosion, Wear and UV Aging Resistance of Epoxy Composite Coatings via Graphene Oxide Incorporation

UV aging, corrosion and wear resistance of epoxy (EP) coatings are all critical for their long-term service in outdoor environments. In this work, graphene oxide (GO) was used as a multifunctional additive in epoxy coatings to improve these properties. Owing to its two-dimensiona...

Selenium Alleviates Mercury Toxicity in Ophiocordyceps sinensis: Mechanistic Insights from Integrated Phenotypic and Transcriptomic Analyses

Ophiocordyceps sinensis, a valuable medicinal and nutritional resource, faces significant mercury (Hg) contamination risks. Total Hg content in some samples from key producing regions exceeds the 0.2 mg/kg limit set by the Chinese Pharmacopoeia, raising ecological and food safety...

A NESO-TD-based dual-loop integral sliding mode control framework for robust trajectory tracking of wheeled mobile robots

Wheeled mobile robots (WMRs) operating on rough outdoor compacted hard ground are susceptible to disturbances caused by model uncertainties and terrain variations, which may degrade trajectory tracking accuracy and robustness. To address this issue, this study proposes a unified...

Negotiating ageing governance: older women’s leisure transitions from plaza dancing to U3A learning in urban China

Numerous studies have highlighted the benefits of leisure for older women, yet the dynamics and consequences of their movements between leisure spaces remain underexplored. Drawing on qualitative fieldwork in two north-western Chinese communities (2024–2025), this paper examines...

Porcine Reproductive and Respiratory Syndrome Virus: Adaptive Immunity, Immune Evasion and Emerging Strategies for Disease Control

Porcine reproductive and respiratory syndrome virus (PRRSV) is one of the most economically important pathogens affecting the global swine industry. This review summarizes current knowledge of PRRSV-induced suppression of adaptive immune responses, with particular emphasis on imp...

A Study on the Responsiveness of Rural Revitalization Planning in Revolutionary Base Areas Based on Multidimensional Value Assessment: A Case Study of Huining County

In the process of rural revitalization, former revolutionary base areas face deep-seated contradictions between their historical contributions and their current development. This study uses 307 village-level administrative units in Huining County, Gansu Province. Based on multi-s...

Gain scheduling multi-model predictive control of the outlet temperature for the molten salt linear Fresnel collector
