INTRODUCTION Surgical navigation systems are increasingly used to aid resection and reconstruction of osseous malignancies. In the process of implementing image-based surgical navigation systems, there are numerous opportunities for error that may impact surgical outcome. This study aimed to examine modifiable sources of error in an idealized scenario, when using a bidirectional infrared surgic...

We show that when estimating a nonparametric regression model, the knearest-neighbor nonparametric estimation method has the ability to remove irrelevant variables provided one uses a product weight function with a vector of smoothing parameters, and the least squares cross validation method is used to select the smoothing parameters. Simulation results are consistent with our theoretical analy...

Our interest in analyzing peptides and proteins arises from the need, during preclinical and clinical studies, to quantify levels of protein and peptide drugs and their metabolites (the process of bioanalysis). To support the predicted increase in peptides and proteins undergoing such studies, we expect that the demand for immunological and LC-MS/MS bioanalytical methods to increase. We have be...

In this text we present a Bayesian system of auditory localisation in distance, azimuth and elevation using binaural cues only. We describe its supporting sensor model and calibration procedure. The binaural system is also integrated in a spatial representation framework for multimodal perception of 3D structure and motion — the Bayesian Volumetric Map (BVM). This solution will enable the imple...
