Visualisation of abnormal morphological development and molecular mechanisms that give rise to tracheo-oesophageal malformations and other VACTERL anomalies in an Adriamycin treated Mouse Model
(Trinity College (Dublin, Ireland). Department of Zoology, 2012)Oesophageal atresia/Tracheo-oesophageal fistula (OA/TOF) are relatively common malfonnations of the foregut in humans (Spitz, 2007). They require urgent corrective surgery after birth and have an impact on the future health ... -
Visualising small world graphs using agglomerative clustering around nodes of interest
(Trinity College (Dublin, Ireland). School of Computer Science & Statistics, 2013)The difficulty of visualising large graphs lies not just in processing power and display size but in the inherent visual complexity of a large data-set, as the noise and clutter from large numbers of nodes and an order of ... -
