Adaptation of speaker-specific bases in non-negative matrix factorization for single channel speech-music separation [PDF]

, 2011
This paper introduces a speaker adaptation algorithm for nonnegative matrix factorization (NMF) models. The proposed adaptation algorithm is a combination of Bayesian and subspace model adaptation. The adapted model is used to separate speech signal from

Resolution of Levodopa/Dopa‐Decarboxylase Inhibitor—Associated Microscopic Colitis with Subcutaneous Foslevodopa/Foscarbidopa: A Case Series and Review of the Literature

Movement Disorders Clinical Practice, EarlyView.
Abstract Background Microscopic colitis (MC) typically presents with chronic, non‐bloody watery diarrhea. Diagnosis requires endoscopy with colonic mucosal biopsies. The etiology is multifactorial, with several medications implicated, although only a few cases have been attributed to oral levodopa/dopa‐decarboxylase inhibitor (LDDCI) therapy.

Next‐Generation Aerogel Electrocatalysts for Oxygen Reduction Reaction

Small, EarlyView.
ABSTRACT Aerogel‐based electrocatalysts have become a groundbreaking class of materials for the oxygen reduction reaction (ORR), distinguished by their ultralight nature, pore networks, and outstanding electrical conductivity. Their interconnected three‐dimensional frameworks offer abundant active sites, efficient diffusion channels, and continuous ...

Generalized Alpha-Beta Divergences and Their Application to Robust Nonnegative Matrix Factorization

Entropy, 2011
We propose a class of multiplicative algorithms for Nonnegative Matrix Factorization (NMF) which are robust with respect to noise and outliers. To achieve this, we formulate a new family generalized divergences referred to as the Alpha-Beta-divergences ...

Spectro-temporal post-smoothing in NMF based single-channel source separation [PDF]

, 2012
In this paper, we propose a new, simple, fast, and effective method to enforce temporal smoothness on nonnegative matrix factorization (NMF) solutions by post-smoothing the NMF decomposition results.

SMILE: Extraction‐free submicron‐resolution mapping of lipid chain length and unsaturation by stimulated Raman imaging

VIEW, EarlyView.
In this work, we develop submicron‐resolution mapping of intracellular lipid elements (SMILE) as an extraction‐free vibrational spectroscopic imaging platform based on hyperspectral stimulated Raman scattering microscopy with a spectral analysis pipeline for pixel‐resolved lipid profiling.

Beyond Distinction: Private Art Museums and Their Versatile Role for Elites' (Self)Legitimization Discourses

The British Journal of Sociology, EarlyView.
ABSTRACT The 2000s have witnessed a significant, worldwide boom in new art museums founded by private, wealthy collectors. While the arts have long been a key arena for the remaking of elite distinction and the reproduction of inequalities, this surge in private museums has sparked much controversy.
