The full scientific papers that have resulted from CATCH research are listed below for you. The articles are listed based on the year in which they were published and with the name of the article. They are listed in a typical scientific format, with the authors listed first, followed by the title of the article, and followed by information about which journal it is published in, the year, issue number of the journal and page numbers. At the end of each listing there is a link to the website where the article can be read and downloaded. In all but a few cases the articles are available free of charge.
