Evaluation of the Tobii EyeX Eye tracking controller and Matlab toolkit for research.

The Tobii Eyex Controller is a new low-cost binocular eye tracker marketed for integration in gaming and consumer applications. The manufacturers claim that the system was conceived for natural eye gaze interaction, does not require continuous recalibration, and allows moderate head movements. The Controller is provided with a SDK to foster the development of new eye tracking applications.

Adaptive and predictive control of a simulated robot arm.

In this work, a basic cerebellar neural layer and a machine learning engine are embedded in a recurrent loop which avoids dealing with the motor error or distal error problem. The presented approach learns the motor control based on available sensor error estimates (position, velocity, and acceleration) without explicitly knowing the motor errors. The paper focuses on how to decompose the input into different components in order to facilitate the learning process using an automatic incremental learning model (locally weighted projection regression (LWPR) algorithm).

Bio-inspired adaptive feedback error learning architecture for motor control.

This study proposes an adaptive control architecture based on an accurate regression method called Locally Weighted Projection Regression (LWPR) and on a bio-inspired module, such as a cerebellar-like engine. This hybrid architecture takes full advantage of the machine learning module (LWPR kernel) to abstract an optimized representation of the sensorimotor space while the cerebellar component integrates this to generate corrective terms in the framework of a control task. Furthermore, we illustrate how the use of a simple adaptive error feedback term allows to use the proposed architecture even in the absence of an accurate analytic reference model.

Percutaneous PFO closure using the Premere device occluder: initial experience.

Introduction: Most data on percutaneous closure of patent foramen ovale (PFO) relate to devices not specifically designed for this pathology.

Objective: Our aim in this article is to share our initial experience with the Premere PFO closure system.

Methods: In our hospital 14 consecutive patients presenting cryptogenic stroke underwent percutaneous closure using this device.

Lower levels of in-stent late loss are not associated with the risk of stent thrombosis in patients receiving drug-eluting stents.

Aims: The aim of this study was to evaluate whether there is any relationship between in-stent late loss (ISLL) and the risk of stent thrombosis (ST) in patients treated with drug eluting stents (DES). The benefit of DES in reducing binary angiographic restenosis and the need for new revascularisation procedures is due to a reduction on ISLL. It has been hypothesised, however, that neointimal hyperplasia could preclude ST, and thus a very low ISLL could increase the risk of ST.
