MR and Ultrasound for Liver Fat Assessment in Children: Techniques and Supporting Evidence

open access: yesJournal of Magnetic Resonance Imaging, Volume 62, Issue 3, Page 691-706, September 2025.
ABSTRACT Hepatic steatosis is a common imaging finding that can be a sign of chronic liver disease, most often associated with metabolic dysfunction‐associated steatotic liver disease (MASLD). Imaging techniques for evaluating steatosis range from basic qualitative assessments to advanced and highly accurate quantitative metrics. Among these, MRI‐based

A methodology for incident detection in sectorized water distribution networks based on pressure and flow data

open access: yesComputer-Aided Civil and Infrastructure Engineering, Volume 40, Issue 20, Page 3013-3032, 18 August 2025.
Abstract This study presents an intelligent system for predicting incident reports (IRs) in sectorized water distribution networks, such as drains in sidewalks, lack of pressure, lack of water, leaks, or others, based on pressure and flow data. Currently, incident detection in the industry is highly inefficient, as it is always performed reactively ...

"Set phasors to stun": an algorithm to improve phase coherence on transients in multi-microphone recordings [PDF]

open access: yes, 2007
Ever since the advent of multi-microphone recording, sound engineers have wrestled with the colouration of sound by phasing issues. For some this was an anathema; for others this colouration was a crucial ingredient of the finished product. Traditionally,

A New Kind of Laser Microphone Using High Sensitivity Pulsed Laser Vibrometer [PDF]

open access: yes, 2008
We demonstrate experimentally a new kind of laser microphone using a highly sensitive pulsed laser vibrometer. By using the photo-electromotive-force (photo-EMF) sensors, we present data indicating the real-time detection of surface displacements as ...

Fingerprinting Smart Devices Through Embedded Acoustic Components [PDF]

open access: yes, 2014
The widespread use of smart devices gives rise to both security and privacy concerns. Fingerprinting smart devices can assist in authenticating physical devices, but it can also jeopardize privacy by allowing remote identification without user awareness.

Method for Assessing the Fidelity of Optical Diffraction Tomography Reconstruction Methods

open access: yes, 2019
We use a spatial light modulator in a diffraction tomographic system to assess the accuracy of different refractive index reconstruction algorithms. Optical phase conjugation principles through complex media, allows us to quantify the error for different

Fluctuating surface pressure measurements on USB wing using two types of transducers [PDF]

open access: yes
Measurements of the fluctuating pressures on the wing surface of an upper-surface-blown powered-lift model and a JT15 engine were obtained using two types of pressure transducers.
