Many smaller dialysis centers are turning to cooperative alliances as a strategy to confront a competitive environment that is characterized by blurring industry boundaries, fast-changing technologies, and global integration. According to Lambe et al. (2002), alliance is broadly defined as the “collaborative efforts between two or more firms in which the firms pool their resources in an effort ...

The editors of Eye and Vision would like to thank all our reviewers who have contributed to the journal in volume 2 (2015).

Stimulus-locked, response-locked, and ERP-locked averaging are effective methods for reducing artifacts in ERP analysis. However, they suffer from a magnifying-glass effect: they increase the resolution of specific ERPs at the cost of blurring other ERPs. Here we propose an extremely simple technique-binning trials based on response times and then averaging-which can significantly alleviate the...

Where do our brains encode all the colours of the rainbow? We know the neural basis for colour opponency and colour contrast, and recent studies have now provided evidence for the representation of hue in cortical visual area V2.

We use the regularization theory in a Bayesian framework to derive a quadratic cost function for denoising fringe patterns. As prior constraints for the regularization problem, we propose a Markov random field model that includes information about the fringe orientation. In our cost function the regularization term imposes constraints to the solution (i.e., the filtered image) to be smooth only...

Colour constancy is typically weaker in the laboratory than it seems in our everyday experience. New measurements using real-world stimuli show that colour constancy is in fact almost perfect, and that several different perceptual mechanisms contribute to achieving it.

• Because this is the eleventh day of the eleventh month I should like this Lecture to be in part a tribute to those that shall not grow old as we that are left grow old. Let us remember them as well as General Mitchiner. It is a very great privilege to be invited to deliver this • Lecture and I am particularly honoured by the fact that • the man who issued the invitation, Sir Cameron Moffat, w...
