1509 Chodosh, Hiram E.Corruption and Its Challenges: The Battle to Stop a Universal ProblemCorruption is increasingly seen as a universal problem, deeply embedded in many national legal systems, and also transnational in nature. It is so endemic that it has generated its own special vernacular, such as Code 1,000 in Honduras (a reference to the 1,000 lempira note), mordida in Mexico...2009-09-25
1510 Gerig, GuidoCortical enhanced tissue segmentation of neonatal brain MR images acquired by a dedicated phased array coilThe acquisition of high quality MR images of neonatal brains is largely hampered by their characteristically small head size and low tissue contrast. As a result, subsequent image processing and analysis, especially for brain tissue segmentation, are often hindered. To overcome this problem, a dedic...2009-01-01
