An indicator dilution method for measuring oscillatory flow in a vessel is analyzed in terms of a mixing chamber with a constant volume. For the correct measurement of mean flow, the time constant of detection of the indicator Should be very much shorter than the shortest time constant of the mixing volume. The performance of such a system was examined with a thermal indicator. Although the app...

Introduction A number of authors have investigated associations between MR vascular parameters and traditional histopathological prognostic markers. Results have varied with some studies revealing correlations while others have failed to find any associations.

Mouse head-fixed behaviour coupled with functional imaging has become a powerful technique in rodent systems neuroscience. However, training mice can be time consuming and is potentially stressful for animals. Here we report a fully automated, open source, self-initiated head-fixation system for mesoscopic functional imaging in mice. The system supports five mice at a time and requires minimal ...

An index is proposed that is based on the h-index and a 3-year publication/citation window. When updated regularly, it shows the current scientific performance of researchers rather than their life-time achievement as indicated by common scientometric indicators. In this respect, the new rating scheme resembles established sports ratings such as in chess or tennis. By the example of ACM SIGMOD ...

Christian M. Dippon Abstract If casual observation is an accurate indicator, consumers make their mobile purchasing decisions based solely on the type of mobile phone that mobile service providers are offering as part of a bundle of services. This raises the question of whether other service bundle components matter to consumers. In light of increased competition and saturation in the US mobile...

BACKGROUND Consumers spend less time and more money on home-prepared foods opting for convenience products such as pre-cooked entrees (Dumagan and Hackett, 1995). However, they demand acceptable color and flavor, whether the product is ready-tocook or ready-to-eat. Color and appearance of fresh meat are major factors in consumer purchase decisions because they are presumed to be indicators of m...
