Hello Everybody, <br>Few days ago, we have submitted a manuscript, reviewing some of our recent work + comparisons to others  + some new results.<br>A pre-print is at:<br><a href="http://arxiv.org/abs/1208.5130">http://arxiv.org/abs/1208.5130</a><br>
<br>The aim of the paper is to provide a mini review especially for those ones who are not very familiar with the field. However, the paper is clearly biased in coverage in favour of our topics of interest and also mentioning only those papers that I come across! Since the first characteristic, being limited in topical coverage, is fine, the second one, potential missing of related papers should be cured as much as possible. <br>
<br>That would be highly appreciated if you could give me feedbacks of any kind, especially on the missing literatures.<br><br>Cheers,<br>.Taha Yasseri<br>
