An iterative, residual-based approach to unsupervised musical source separation in single-channel mixtures [PDF]

, 2009
This thesis concentrates on a major problem within audio signal processing, the separation of source signals from musical mixtures when only a single mixture channel is available.

Distinguishing microgliosis and tau deposition in the mouse brain using paramagnetic and diamagnetic susceptibility source separation. [PDF]

Imaging Neurosci (Camb)
Abstract Tauopathies, including Alzheimer’s disease (AD), are neurodegenerative disorders characterized by hyperphosphorylated tau protein aggregates in the brain. In addition to protein aggregates, microglia-mediated inflammation and iron dyshomeostasis are other pathological features observed in AD and other tauopathies. It is known

Depth-wise profiles of iron and myelin in the cortex and white matter using χ-separation: A preliminary study

NeuroImage, 2023
The in-vivo profiling of iron and myelin across cortical depths and underlying white matter has important implications for advancing knowledge about their roles in brain development and degeneration.

Susceptibility Source Separation Unveils Paramagnetic and Diamagnetic Trajectories in Healthy Brains From 5 to 90 Years. [PDF]

NMR Biomed
ABSTRACT Susceptibility source separation (SSS) enables independent evaluation of both paramagnetic iron and diamagnetic myelin in the human brain. The aim of this work was to analyze healthy brain lifespan trajectories of paramagnetic and diamagnetic susceptibilities in deep gray matter (DGM) and white matter (WM) from a large ...

A review on the analysis of aeromagnetic anomaly and its geological and tectonic applications

地球与行星物理论评, 2022
Aeromagnetic anomaly has the obvious advantages of wide coverage, low cost and high lateral resolution in geological structure research, and has been widely used in concealed magmatic rock and faults detection, tectonic characteristics (e.g.

Estimating blood oxygen saturation through susceptibility source separation: A new standpoint on quantitative BOLD models. [PDF]

J Cereb Blood Flow Metab
Motivation: MR methods have been proposed to estimate blood oxygen saturation (SO2) in cerebral tissues by exploiting the magnetic susceptibility difference between oxy and deoxyhemoglobin. These models neglect the contribution of extravascular susceptibility sources leading to inaccurate measurements.

WaveSep: A Flexible Wavelet-Based Approach for Source Separation in Susceptibility Imaging

, 2023
The separation of signal contributions from paramagnetic and diamagnetic susceptibility sources in MRI has important implications for understanding the biological functions and health conditions of the brain. However, general and flexible deep-learning-based tools that can provide this information in humans in vivo are limited.
