ISPRS International Journal of Geo-Information, 2021 The increase in atmospheric pollution dominated by particles with an aerodynamic diameter smaller than 2.5 μm (PM2.5) has become one of the most serious environmental hazards worldwide. The geographically weighted regression (GWR) model is a vital method

Stationarity and Non-Stationarity in Immigrant Problem Discourse: 'The Politics of Migrant Youth'
Nordic Journal of Migration Research, 2011 This article dissects debates about the "immigrant youth" over time, using the difference between stationary and non-stationary processes as the primary analytical tool.

Non-stationarity in the "resting brain's" modular architecture. [PDF]
PLoS ONE, 2012 Task-free functional magnetic resonance imaging (TF-fMRI) has great potential for advancing the understanding and treatment of neurologic illness. However, as with all measures of neural activity, variability is a hallmark of intrinsic connectivity ...

Correcting for Non-stationarity in BOLD-fMRI Connectivity Analyses
Frontiers in Neuroscience, 2021 In this work fMRI BOLD datasets are shown to contain slice-dependent non-stationarities. A model containing slice-dependent, non-stationary signal power is proposed to address time-varying signal power during BOLD data acquisition.

Exploring age-related changes in dynamical non-stationarity in electroencephalographic signals during early adolescence. [PDF]
PLoS ONE, 2013 Dynamics of brain signals such as electroencephalogram (EEG) can be characterized as a sequence of quasi-stable patterns. Such patterns in the brain signals can be associated with coordinated neural oscillations, which can be modeled by non-linear ...

Anais da Academia Brasileira de Ciências, 2022 Estimating the probability of occurrence of extreme hydrologic events is a fundamental input in the design of hydraulic infrastructure. The classical approach to this problem has been to fit parametric probability functions to annual maxima streamflow ...

A Spatially Non-stationary Fading Channel Model for Simulation and (Semi-) Analytical Study of ELAA-MIMO [PDF]
arXiv, 2023 In this paper, a novel spatially non-stationary fading channel model is proposed for multiple-input multiple-output (MIMO) system with extremely-large aperture service-array (ELAA). The proposed model incorporates three key factors which cause the channel spatial non-stationarity: 1) link-wise path-loss; 2) shadowing effect; 3) line-of-sight (LoS)/non ...

Frontiers in Marine Science, 2022 Species distribution models (SDMs) are a commonly used tool, which when combined with earth system models (ESMs), can project changes in organismal occurrence, abundance, and phenology under climate change.

Non-Stationarity-Based Adaptive Segmentation Applied to Voice Disorder Discrimination
IEEE Access, 2023 Voice disorders can affect people in all age groups. Vocal health is especially important when voice is used as a work tool, as in the fields of education (teachers), music (singers) and multimedia (journalists).
