Construction of long-term (2003–2024) DIN dataset in the Chinese coastal ocean using interpretable ML

Ecological Informatics
Monitoring dissolved inorganic nitrogen (DIN) concentration in coastal ocean is essential for better understanding eutrophication processes, biogeochemical cycling, and ecosystem responses to anthropogenic and climate changes.

Fusing Mobile Phone and Travel Survey Data to Model Urban Activity Dynamics

Journal of Advanced Transportation, 2020
A key issue to understand urban system is to characterize the activity dynamics in a city—when, where, what, and how activities happen in a city. To better understand the urban activity dynamics, city-wide and multiday activity participation sequence ...

NONPARAMETRIC MODELING AND SPATIOTEMPORAL DYNAMICAL SYSTEMS [PDF]

International Journal of Bifurcation and Chaos, 2004
This article describes how to use statistical data analysis to obtain models directly from data. The focus is put on finding nonlinearities within a generalized additive model. These models are found by means of backfitting or more general algorithms, like the alternating conditional expectation value one.

Spatiotemporal dynamics of bilingual word processing [PDF]

NeuroImage, 2010
Studies with monolingual adults have identified successive stages occurring in different brain regions for processing single written words. We combined magnetoencephalography and magnetic resonance imaging to compare these stages between the first (L1) and second (L2) languages in bilingual adults. L1 words in a size judgment task evoked a typical left-

The Atlantic Forest of South America: Spatiotemporal dynamics of the vegetation and implications for conservation [PDF]

The Atlantic Forest in South America (AF) is one of the world's most diverse and threatened biodiversity hotspots. We present a comprehensive spatiotemporal analysis of 34 years of AF landscape change between 1986 and 2020.

Identifying multi-scale human flow clusters via spatiotemporal network flow L function

International Journal of Applied Earth Observations and Geoinformation
Understanding spatiotemporal clustering patterns of human flows is critical for interpreting mobility dynamics and addressing urban issues. Ripley’s K-function, distinguished by its non-parametric and multi-scale properties, provides an effective method ...

Spatiotemporal dynamics of audiovisual speech processing [PDF]

NeuroImage, 2008
The cortical processing of auditory-alone, visual-alone, and audiovisual speech information is temporally and spatially distributed, and functional magnetic resonance imaging (fMRI) cannot adequately resolve its temporal dynamics. In order to investigate a hypothesized spatiotemporal organization for audiovisual speech processing circuits, event ...

Analysis of Global and Key PM_2.5 Dynamic Mode Decomposition Based on the Koopman Method

Atmosphere
Understanding the spatiotemporal dynamics of atmospheric PM2.5 concentration is highly challenging due to its evolution processes have complex and nonlinear patterns. Traditional mode decomposition methods struggle to accurately capture the mode features
