Localized thin-section CT with radiomics feature extraction and machine learning to classify early-detected pulmonary nodules from lung cancer screening.
Physics in medicine and biology
Mar 14, 2018
Lung cancer screening aims to detect small pulmonary nodules and decrease the mortality rate of those affected. However, studies from large-scale clinical trials of lung cancer screening have shown that the false-positive rate is high and positive pr...
Spine morphology and energetics: how principles from nature apply to robotics.
Bioinspiration & biomimetics
Mar 14, 2018
Inspired by the locomotive advantages that an articulated spine enables in quadrupedal animals, we explore and quantify the energetic effect that an articulated spine has in legged robots. We compare two model instances of a conceptual planar quadrup...
Sensory characterization and acceptance of coffee brews of C. arabica and C. canephora blended with steamed defective coffee.
Food research international (Ottawa, Ont.)
Mar 13, 2018
Steam treatment has been reported as an alternative to improve the cup quality of coffee; in this research, it was applied to C. canephora defective coffee. The aim of the study was to evaluate the sensory perception of steamed defective C. canephora...

Bayesian estimation of multidimensional latent variables and its asymptotic accuracy.
Neural networks : the official journal of the International Neural Network Society
Mar 13, 2018
Hierarchical learning models, such as mixture models and Bayesian networks, are widely employed for unsupervised learning tasks, such as clustering analysis. They consist of observable and latent variables, which represent the given data and their un...
Design and validation of an ontology-driven animal-free testing strategy for developmental neurotoxicity testing.
Toxicology and applied pharmacology
Mar 13, 2018
Developmental neurotoxicity entails one of the most complex areas in toxicology. Animal studies provide only limited information as to human relevance. A multitude of alternative models have been developed over the years, providing insights into mech...
Grader Variability and the Importance of Reference Standards for Evaluating Machine Learning Models for Diabetic Retinopathy.
Ophthalmology
Mar 13, 2018
PURPOSE: Use adjudication to quantify errors in diabetic retinopathy (DR) grading based on individual graders and majority decision, and to train an improved automated algorithm for DR grading.
Salvage HDR Brachytherapy: Multiple Hypothesis Testing Versus Machine Learning Analysis.
International journal of radiation oncology, biology, physics
Mar 13, 2018
PURPOSE: Salvage high-dose-rate brachytherapy (sHDRB) is a treatment option for recurrences after prior radiation therapy. However, only approximately 50% of patients benefit, with the majority of second recurrences after salvage brachytherapy occurr...
A trial of retrofitted advisory collision avoidance technology in government fleet vehicles.
Accident; analysis and prevention
Mar 13, 2018
In-vehicle collision avoidance technology (CAT) has the potential to prevent crash involvement. In 2015, Transport for New South Wales undertook a trial of a Mobileye 560 CAT system that was installed in 34 government fleet vehicles for a period of s...
Automated objective robot-assisted assessment of wrist passive ranges of motion.
Journal of biomechanics
Mar 13, 2018
The measurement of wrist passive ranges of motion (ROMs) can provide insight into improvements and allow for effective monitoring during a rehabilitation program. Compared with conventional methods, this study proposed a new robotic assessment techni...
Big Data Toolsets to Pharmacometrics: Application of Machine Learning for Time-to-Event Analysis.
Clinical and translational science
Mar 13, 2018
Additional value can be potentially created by applying big data tools to address pharmacometric problems. The performances of machine learning (ML) methods and the Cox regression model were evaluated based on simulated time-to-event data synthesized...
