Spatial Downscaling of IMERG Considering Vegetation Index Based on Adaptive Lag Phase

IEEE Transactions on Geoscience and Remote Sensing, 2022
High spatial resolution precipitation data are important for hydrological modeling and meteorological applications, especially at regional scales. Statistical downscaling methods for satellite precipitation products using the normalized difference vegetation index (NDVI) have been carried out in many regions to provide high spatial resolution ...

Volume conduction effects in brain network inference from electroencephalographic recordings using phase lag index

Journal of Neuroscience Methods, 2012
In this paper, we test the performance of a synchronicity estimator widely applied in Neuroscience, phase lag index (PLI), for brain network inference in EEG. We implement the four sphere head model to simulate the volume conduction problem present in EEG recordings and measure the activity at the scalp of surrogate sources located at the brain level ...

A novel index of functional connectivity: phase lag based on Wilcoxon signed rank test

Cognitive Neurodynamics, 2020
Phase synchronization has been an effective measurement of functional connectivity, detecting similar dynamics over time among distinct brain regions. However, traditional phase synchronization-based functional connectivity indices have been proved to have some drawbacks.

Phase lag index-based graph attention networks for detecting driving fatigue

Review of Scientific Instruments, 2021
It is important to understand the changes in the characteristics of the brain network in the state of driving fatigue and to reveal the pattern of functional connectivity between brain regions when fatigue occurs. This paper proposes a method for the detection of driving fatigue based on electroencephalogram (EEG) signals using a phase lag index graph ...
