The Compositae is one of the largest and most economically important families of flowering plants and includes a diverse array of food crops, horticultural crops, medicinals, and noxious weeds. Despite its size and economic importance, there is no reference genome sequence for the Compositae, which impedes research and improvement efforts. We report on(More)
(Vieglais et al., 2000). Museum data are high quality because voucher specimens can be examined if identification is questionable. However, like all point data, museum specimens provide only a limited view of the actual species' range (Krohn, 1996), hence the need for predictive approaches. A limited number of ecological data sets are also available,(More)
Portfolio theory is central to the analysis of risk in many areas of economics but is seldom used appropriately in health economics. This contribution examines the use of portfolio theory in the context of cost-effectiveness analysis (CEA). A number of modifications are needed to apply portfolio analysis to the economic evaluation of health care(More)
For specific applications of infrared thermography (IRT) in the field of human medicine diagnosis, well defined standard operating procedures are used (e.g. controlled ambient conditions). In contrast, when IRT is used in the veterinary and animal science field, examinations are not always performed under controlled ambient conditions. This leads to(More)
Thermolability of complex biological molecules is a major consideration for the long-term maintenance of titer during periods of storage. The development of a simple, cost effective method for long term storage of virus samples, which maintains viral titer would prove useful for a wide variety of applications including the preservation of viral vaccines,(More)
The Office of Research and Development of the Federal Railroad Administration (FRA) is sponsoring a revenue service demonstration of an on-board condition monitoring system for freight trains. The objective of the system is to improve railroad safety and efficiency through continuous monitoring of mechanical components to detect defects before they cause(More)
A method is presented for predicting brake shoe force of a rail vehicle as a linear function of effective brake cylinder pressure. Historically, the braking force has been calculated as the product of cylinder pressure, cylinder area, rigging leverage ratio, and an overall system efficiency factor. The efficiency factor, which takes into account frictional(More)
