What does it take to qualify as a “problem for the twenty-first century?” Obviously, the topic must be of fundamental importance, it must be difficult to solve as manifested by the number of excellent people who have tried—but failed, and non-experts should be able to appreciate the basic issues.

Although early goal-directed therapy (EGDT) has been a landmark in guiding the approach to patients with sepsis in the ED, few institutions seem willing and able to adopt it for all eligible patients. 1 The complexity and invasiveness of the protocol are the most frequently cited barriers.

Color appearance models provide a powerful tool for achieving a viewing condition independent color representation. However, current color appearance models such as CIECAM97s and CAM97s2 are more complex than previous CIE device independent color spaces, such as CIELAB and CIELUV. Therefore it is important to understand how to correctly measure and set the input parameters. This paper provides ...

Despite recent advances in the understanding of the interplay between a dynamic physical environment and phylogeography in Europe, the origins of contemporary Irish biota remain uncertain. Current thinking is that Ireland was colonized post-glacially from southern European refugia, following the end of the last glacial maximum (LGM), some 20 000 years BP. The Leisler's bat (Nyctalus leisleri), ...
