An acoustic signature of extreme failure on model granular materials

open access: yesScientific Reports, 2022
Unexpectedly, granular materials can fail, the structure even destroyed, spontaneously in simple isotropic compression with stick-slip-like frictional behaviour.

Geometric and dosimetric evaluation of a commercial AI auto‐contouring tool on multiple anatomical sites in CT scans

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Current radiotherapy practices rely on manual contouring of CT scans, which is time‐consuming, prone to variability, and requires highly trained experts. There is a need for more efficient and consistent contouring methods. This study evaluated the performance of the Varian Ethos AI auto‐contouring tool to assess its potential integration into

Physical Activity, the Compression of Morbidity, and the Health of the Elderly [PDF]

open access: yesJournal of the Royal Society of Medicine, 1996
The Compression of Morbidity hypothesis envisions a potential reduction of overall morbidity, and of health care costs, now heavily concentrated in the senior years, by compression of morbidity between an increasing age of onset of disability and the age of death, increasing perhaps more slowly1,2.

Numerical investigation of blanking for metal polymer sandwich sheets

open access: yesMATEC Web of Conferences, 2016
Metal polymer sandwich sheets consist of materials with drastically different mechanical properties. Due to this fact and because of high local gradients in the cutting zone during the blanking process, traditional process strategies and empirical ...

Toward a human‐centric co‐design methodology for AI detection of differences between planned and delivered dose in radiotherapy

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Introduction Many artificial intelligence (AI) solutions have been proposed to enhance the radiotherapy (RT) workflow, but limited applications have been implemented to date, suggesting an implementation gap. One contributing factor to this gap is a misalignment between AI systems and their users.

Shear-Wave Elastography: Basic Physics and Musculoskeletal Applications.

open access: yesRadiographics, 2017
In the past 2 decades, sonoelastography has been progressively used as a tool to help evaluate soft-tissue elasticity and add to information obtained with conventional gray-scale and Doppler ultrasonographic techniques.

Diagnostic image‐based treatment planning for online adaptive ultra‐hypofractionated prostate cancer radiotherapy with MR‐Linac

open access: yesJournal of Applied Clinical Medical Physics, EarlyView.
Abstract Purpose A new workflow was investigated for Elekta Unity MR‐Linac by removing the computed tomography (CT)‐simulation step and using diagnostic CT (DCT) for reference plan generation. Materials and methods Ten patients with ultra‐hypofractionated prostate cancer treated with magnetic resonance imaging (MRI)‐guided adaptive radiotherapy were ...

Learning physical descriptors for materials science by compressed sensing

open access: yesNew Journal of Physics, 2017
The availability of big data in materials science offers new routes for analyzing materials properties and functions and achieving scientific understanding. Finding structure in these data that is not directly visible by standard tools and exploitation of the scientific information requires new and dedicated methodology based on approaches from ...

Compression of dynamic tactile information in the human hand

open access: yesScience Advances, 2020
The mechanics of wave transmission in the human hand effect the preneuronal compression of tactile information. A key problem in the study of the senses is to describe how sense organs extract perceptual information from the physics of the environment ...
