Submissions are solicited for the workshop to be held on December 11th/ 12th 2009 at this year's NIPS workshop session in Whistler, Canada. This workshop will focus on the role of parallel computation in Submission to this journal proceeds totally online at http://ees.elsevier.com/parco/ and you will be guided stepwise through the creation and uploading of your files. The system automatically converts source files to a single PDF file of the article, which is used in the peer-review process.

All correspondence, including notification of the Editor's decision and requests for revision, takes place by e-mail removing the need for a paper trail. we are pleased to announce that a Special Session on Complex-Valued Neural Networks will be organized at the 2010 International Joint Conference on Neural Networks (IJCNN-2010), which this time will be a part of 2010 IEEE World Congress on Computational Intelligence. The MAIN MEETING is organized in a single track, and consists of both oral and poster sessions. Some oral presentations are invited (see below), while others are selected based on short submitted abstracts. Poster presentations are also selected from the submitted abstracts.
