Landmarks and ant search strategies after interrupted tandem runs [PDF]
Journal of Experimental Biology, 2013 Summary During a tandem run, a single leading ant recruits a single follower to an important resource such as a new nest. Here, for the first time, we used a motorized gantry to track tandem running ants accurately in a large arena and we compared their performance in the presence of different types of landmark.

TD-COF: A new method for detecting tandem duplications in next generation sequencing data
SoftwareXTandem duplications significantly influence the diversity of the human genome and the occurrence of many complex diseases. However, accurate detection of tandem duplications of low coverage remains a challenging task. Based on RD (read depth), the tandem
