Enabling Metal‐Based Soft Robotics Through Investment Casting

Advanced Intelligent Systems, EarlyView.
Vacuum investment casting enables manufacturing of compliant soft robotic structures out of AA7075 high‐strength aluminum alloy. Additively manufactured patterns are converted into metal soft robotic structures addressing long lasting challenges like durability and nonlinearity of elastomer‐based soft robotics.

Surface dose measurements and comparison of unflattened and flattened photon beams

Journal of Medical Physics, 2016
The purpose of this study was to evaluate the central axis dose in the build-up region and the surface dose of a 6 MV and 10 MV flattened photon beam (FB) and flattening filter free (FFF) therapeutic photon beam for different square field sizes (FSs) for

Reproducing Quantum Probability Distributions at the Speed of Classical Dynamics: A New Approach for Developing Force-Field Functors

, 2017
Modeling nuclear quantum effects is required for accurate molecular dynamics (MD) simulations of molecules. The community has paid special attention to water and other biomolecules that show hydrogen bonding.

“The purpose of activism is to educate”: Young people's climate activism as and for education in the youth strike movement in England

British Educational Research Journal, EarlyView.
Abstract By skipping school for their cause, young climate strikers repeatedly demonstrated their priorities in 2019 and 2020. They regularly chose to sacrifice a day of their formal education in favour of collective action. This study asks what we can learn from the reflections of former youth strikers.

New in-sample prediction errors in time series with applications [PDF]

, 2001
^aThis article introduces two new types of prediction errors in time series: the filtered prediction errors and the deletion prediction errors. These two prediction errors are obtained in the same sample used for estimation, but in such a way that they ...

Design and implementation of a 3D‐printed modular distillation tower for experimental teaching in chemical engineering

The Canadian Journal of Chemical Engineering, EarlyView.
Abstract Several authors have reported the disconnection between the skills, abilities, and attitudes of graduates from STEM careers with the current needs of the labour market. In science and engineering fields, research has found the need for interdisciplinary approaches that encourage meaningful learning.

Human Health Risk Assessment From Exposure to Toxic Metals in Soils and Leafy Vegetables in Smallholder Farms of Northeastern Brazil

Journal of Applied Toxicology, EarlyView.
ABSTRACT This study assessed human health risks associated with exposure to potentially toxic metals (PTMs) in soils and leafy vegetables cultivated in smallholder agricultural systems in Northeastern Brazil. Soil and vegetable samples were collected from 18 agricultural areas and analyzed for cadmium (Cd), chromium (Cr), copper (Cu), iron (Fe), nickel

Symmetries of Three Harmonically-Trapped Particles in One Dimension

, 2012
We present a method for solving trapped few-body problems and apply it to three equal-mass particles in a one-dimensional harmonic trap, interacting via a contact potential.

Comparative Evaluation of Four Stereotactic Radiosurgery Planning Approaches for Treatment of Posterior Choroidal Melanoma

Journal of Medical Radiation Sciences, EarlyView.
This study evaluated four stereotactic radiosurgery planning approaches for posterior choroidal melanoma (CM). Analysis of thirteen CM cases resulted in a clinically meaningful reduction in dose to the brain for Brainlab Elements modulated arcs (BE) and Varian Eclipse HyperArc modulated arcs (HA) compared to Brainlab iPlan dynamic conformal arc therapy
