Minimization of cortical prediction errors has been considered a key computational goal of the cerebral cortex underlying perception, action, and learning. However, it is still unclear how the cortex should form and use information about uncertainty in this process. Here, we formally derive neural dynamics that minimize prediction errors under the assumption that cortical areas must not only predict the activity in other areas and sensory streams but also jointly project their confidence (inverse expected uncertainty) in their predictions.

In such processes, nanoparticle accumulation in ring-shaped structures remains the main obstacle to the synthesis of high-quality coatings containing abundant, small-scale, and evenly dispersed nanoparticles. These local buildups appear after a colloidal droplet evaporates from a substrate.

Current data regarding the prognosis of active cancer in patients undergoing transcatheter aortic valve replacement are conflicting.
Aim: To determine the impact and prognosis of active cancer in transcatheter aortic valve replacement.
Background: During COVID-19 pandemic, visits have been prohibited in most French ICUs. Psychological effects, for reference persons (RPs), of remote-only communication have been assessed.
Methods: All RPs of patients referred to ICU for COVID-19 were included.
Photocatalytic surfaces have the potentiality to respond to many of nowadays societal concerns such as clean H generation, CO conversion, organic pollutant removal or virus inactivation. Despite its numerous superior properties, the wide development of TiO photocatalytic surfaces suffers from important drawbacks. Hence, the high temperature usually required (> 450 °C) for the synthesis of anatase TiO is still a challenge to outreach.
