Acoustical Features as Knee Health Biomarkers: A Critical Analysis
David Atienza Alonso, Vincent Stadelmann, Tomas Teijeiro Campo, Jérôme Paul Rémy Thevenot, Christodoulos Kechris
Acoustical knee health assessment has long promised an alternative to clinically available medical imaging tools, but this modality has yet to be adopted in medical practice. The field is currently led by machine learning models processing acoustical featu ...
2024Deep learning diagnostic and severity-stratification for interstitial lung diseases and chronic obstructive pulmonary disease in digital lung auscultations and ultrasonography: clinical protocol for an observational case-control study
BackgroundInterstitial lung diseases (ILD), such as idiopathic pulmonary fibrosis (IPF) and non-specific interstitial pneumonia (NSIP), and chronic obstructive pulmonary disease (COPD) are severe, progressive pulmonary disorders with a poor prognosis. Prom ...
BMC2023Concurrent Evolution of Biomechanical and Physiological Parameters With Running-Induced Acute Fatigue
Kamiar Aminian, Anisoara Ionescu, Salil Apte, Gaëlle Prigent, Vincent Gremeaux
Understanding the influence of running-induced acute fatigue on the homeostasis of the body is essential to mitigate the adverse effects and optimize positive adaptations to training. Fatigue is a multifactorial phenomenon, which influences biomechanical, ...
FRONTIERS MEDIA SA2022Unsupervised Voice Activity Detection by Modeling Source and System Information using Zero Frequency Filtering
Mathew Magimai Doss, Eklavya Sarkar
Voice activity detection (VAD) is an important pre-processing step for speech technology applications. The task consists of deriving segment boundaries of audio signals which contain voicing information. In recent years, it has been shown that voice source ...
2022Radical Intangibles: Materializing the Ephemeral
Sarah Irene Brutton Kenderdine, Lillian Hibberd, Jeffrey Shaw
New materialism considers that the world and its histories are produced by a range of material forces that extend from the physical and the biological to the psychological, social and cultural. In recognizing that heritage is not held in objects alone, new ...
2021Electrical Signal Modeling in Cochlear Implants. Study of Temperature and Humidity Effects
The present paper discusses the climatic effects of humidity and temperature on cochlear implant functioning and the quality of the electrical sound signal. MATLAB Simulink simulations were prepared, offering insights into signal behavior under such climat ...
MDPI2021Multi-task Neural Network for Robust Multiple Speaker Embedding Extraction
Jean-Marc Odobez, Petr Motlicek, Weipeng He
This paper introduces a novel approach for extracting speaker embeddings from audio mixtures of multiple overlapping voices. This approach is based on a multi-task neural network. The network first extracts a latent feature for each direction. This feature ...
ISCA-INT SPEECH COMMUNICATION ASSOC2021Viscoelastic surface electrode arrays to interface with viscoelastic tissues
Stéphanie Lacour, Alix Esther Anne Trouillet, Nicolas Vachicouras, Florian Dylan Fallegger, Christina Myra Tringides
Bioelectronic interfacing with living tissues should match the biomechanical properties of biological materials to reduce damage to the tissues. Here, the authors present a fully viscoelastic microelectrode array composed of an alginate matrix and carbon-b ...
NATURE RESEARCH2021Walsh-Hadamard-Based Orthogonal Sampling Technique for Parallel Neural Recording Systems
Alexandre Schmid, Reza Ranjandish
Walsh-Hadamard based orthogonal sampling of signals is studied in this paper, and an application of this technique is presented. Using orthogonal sampling, a single analog-to-digital converter (ADC) only is sufficient to perform parallel (simultaneous) rec ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2021Deep Learning Approaches for Auditory Perception in Robotics
Auditory perception is an essential part of a robotic system in Human-Robot Interaction (HRI), and creating an artificial auditory perception system that is on par with human has been a long-standing goal for researchers. In fact, this is a challenging res ...
