Virtualization as a New Scaling Law for Semiconductor Devices Beyond Geometric Scaling

Small, EarlyView.
AI‐enabled semiconductor scaling law. Virtualization emerges as an AI‐enabled scaling law for semiconductors, where progress depends on replacing physical iteration with credible virtual evidence. Surrogate modeling accelerates design‐space exploration, digital twins virtualize process learning, and defect‐to‐reliability inference advances ...

Pressure Fluctuations in the S-Shaped Region of a Reversible Pump-Turbine

Energies, 2017
Numerical simulations were performed to investigate pressure fluctuations in the S-shaped region of a pump-turbine model. Analyses focused on pressure fluctuations in the draft tube and in the gap between the guide vanes and runner.

Machine Learning on Systematically Curated Data Reveals Key Determinants of Magnetic Hyperthermia Performance

Small, EarlyView.
This study presents a machine‐learning (ML) framework to predict the specific absorption rate (SAR) of superparamagnetic iron oxide nanoparticles (SPIONs) for magnetic hyperthermia. A curated dataset comprising 30 intrinsic and extrinsic features revealed strong nonlinear dependencies.

Unsteady hydraulic simulation of the cavitating part load vortex rope in Francis turbines

Journal of Physics: Conference Series, 2017
For Francis turbines at part load operation a helical vortex rope is formed due to the swirling nature of the flow exiting the runner. This vortex creates pressure fluctuations which can lead to power swings, and the unsteady loading can lead to fatigue damage of the runner.

125 years of exploration and research at Gough's Cave (Somerset, UK) 125 ans d'exploration et de recherches à Gough's Cave (Somerset, Royaume‐Uni)

Journal of the Royal Anthropological Institute, EarlyView.
Our understanding of the recolonization of northwest Europe in the period leading up to the Lateglacial Interstadial relies heavily on discoveries from Gough's Cave (Somerset, UK). Gough's Cave is the richest Late Upper Palaeolithic site in the British Isles, yielding an exceptional array of human remains, stone and organic artefacts, and butchered ...

Hydroacoustic Modeling of a Cavitation Vortex Rope for a Francis Turbine

, 2015
Hydraulic machines subject to off-design operation involve the presence of cavitating flow regimes in the draft tube. The cavitation vortex rope at part load conditions is described as an excitation source for the hydraulic system, and interactions between this excitation source and system eigenfrequency may result in resonance phenomena and induce a ...
