Indoor Positioning System Using Magnetic Field Map Navigation and an Encoder System [PDF]

Sensors, 2017
In the indoor environment, variation of the magnetic field is caused by building structures, and magnetic field map navigation is based on this feature. In order to estimate position using this navigation, a three-axis magnetic field must be measured at ...

Visual field map clusters in human frontoparietal cortex [PDF]

eLife, 2017
The visual neurosciences have made enormous progress in recent decades, in part because of the ability to drive visual areas by their sensory inputs, allowing researchers to define visual areas reliably across individuals and across species.

Using synthetic MR images for distortion correction

Developmental Cognitive Neuroscience, 2023
Functional MRI (fMRI) data acquired using echo-planar imaging (EPI) are highly distorted by magnetic field inhomogeneities. Distortion and differences in image contrast between EPI and T1-weighted and T2-weighted (T1w/T2w) images makes their alignment a ...

Seiberg-Witten map for D-branes in large R-R field background

Journal of High Energy Physics, 2021
We obtain a Seiberg-Witten map for the gauge sector of multiple Dp-branes in a large R-R (p − 1)-form field background up to the first-order in the inverse R-R field background.
