    • Do Seasons Have an Influence on the Incidence of Depression? The Use of an Internet Search Engine Query Data as a Proxy of Human Affect 

      Yang, Albert C.; Huang, Norden E.; Peng, Chung-Kang; Tsai, Shih-Jen (Public Library of Science, 2010)
      Background: Seasonal depression has generated considerable clinical interest in recent years. Despite a common belief that people in higher latitudes are more vulnerable to low mood during the winter, it has never been ...

    • Evolution of In-Group Favoritism 

      Fu, Feng; Tarnita, Corina Elena; Christakis, Nicholas Alexander; Wang, Long; Rand, David Gertler; Nowak, Martin A. (Nature Publishing Group, 2012)
      In-group favoritism is a central aspect of human behavior. People often help members of their own group more than members of other groups. Here we propose a mathematical framework for the evolution of in-group favoritism ...

    • Segmentation of Multi-Isotope Imaging Mass Spectrometry Data for Semi-Automatic Detection of Regions of Interest 

      Gormanns, Philipp; Reckow, Stefan; Poczatek, J. Collin; Turck, Christoph W.; Lechene, Claude P. (Public Library of Science, 2012)
      Multi-isotope imaging mass spectrometry (MIMS) associates secondary ion mass spectrometry (SIMS) with detection of several atomic masses, the use of stable isotopes as labels, and affiliated quantitative image-analysis ...

    • Square-Cut: A Segmentation Algorithm on the Basis of a Rectangle Shape 

      Egger, Jan; Kapur, Tina; Dukatz, Thomas; Kolodziej, Malgorzata; Zukić, Dženan; Freisleben, Bernd; Nimsky, Christopher (Public Library of Science, 2012)
      We present a rectangle-based segmentation algorithm that sets up a graph and performs a graph cut to separate an object from the background. However, graph-based algorithms distribute the graph's nodes uniformly and ...
