Spatiotemporal Variation in Fractional Vegetation Coverage and Quantitative Analysis of Its Driving Forces: A Case Study in the Tabu River Basin, Northern China, 1986–2023
Published 2025-07-01“…The results revealed that: (1) the FVC exhibits considerable spatial heterogeneity, with higher values observed in the southeastern and southwestern areas and lower values in the northern part; (2) over the past 38 years, the annual average FVC has shown fluctuations, with a slight declining trend, while the Hurst exponent indicates a reverse persistence pattern in the FVC across the TRB; and (3) the correlation between the FVC and the temperature is marginally stronger than that with precipitation, and the influence of climate change on promoting the FVC outweighs the role of human activities. …”

Assessment of Urban Flood Resilience Under a Novel Framework and Method: A Case Study of the Taihu Lake Basin
Published 2025-06-01“…Spanning 1999–2020, the analysis reveals three key insights: (1) weight allocation via GTCWM identifies defense capacity (0.224) and hazard (0.224) as dominant dimensions, with drainage pipeline density (0.091), flood-season precipitation (0.087), and medical capacity (0.085) ranking as the top three weighted indicators; (2) temporal trends show an overall upward trajectory in UFR, interrupted by a sharp decline in 2011 due to extreme hazard events, with Shanghai and Hangzhou exhibiting the highest UFR levels, contrasting Zhenjiang’s persistently low UFR; (3) spatial patterns reveal stronger UFR in southern and eastern areas and weaker resilience in northern and western regions. …”

Multistation Wind Speed Forecasting Based on Dynamic Spatiotemporal Graph Convolutional Networks
Published 2025-01-01“…However, spatiotemporal correlations of wind speed are dynamically influenced by weather conditions, seasonal variations, and diurnal fluctuations, resulting in constantly changing spatiotemporal patterns. Meanwhile, wind speed data inherently include short-term high-frequency fluctuations and long-term low-frequency trends, which traditional methods struggle to adapt to and accurately capture multiscale features. …”

Comparative Analysis of Attention Mechanisms in Densely Connected Network for Network Traffic Prediction
Published 2025-06-01“…However, it is known that such convolution layers can only barely capture long-term spatial and temporal dependencies. To solve this problem, we propose Attention-DenseNet (ADNet), which effectively incorporates an attention module into STDenseNet to learn representations for long-term spatio-temporal patterns. …”

The complexity of a “simple” predator–prey system: non-trophic positive interactions generate unsuspected dynamics and dependencies
Published 2025-05-01“…<p>In natural ecosystems, many species engage simultaneously in both trophic and non-trophic interactions (NTIs), influencing each other's population growth and patterns of local coexistence. However, in coastal marine systems, where the larvae of most benthic adults disperse and frequently settle into populations distant from their origin, populations do not experience feedback from local reproduction. …”
