On the Value of Flexibility in R&D Projects
Management Science, 2005In this paper, we consider whether an increase in uncertainty increases the value of a research and development (R&D) project. We also consider the related question of the impact of increased project uncertainty on the value of management flexibility, defined as the difference in value when the project is managed “actively” versus when it is under

The Nutritive Value and Safety of D-Phenylalanine and D-Tyrosine in Mice
The Journal of Nutrition, 1984Growth studies in mice fed synthetic amino acid diets showed that: 1) the biological utilization of D-phenylalanine relative to its L-isomer ranged from 28-81%, depending on the respective concentrations of these amino acids in the diet; 2) L-tyrosine can replace about one-half of the L-phenylalanine needed to achieve maximum weight gain and 3) D ...

Physics Bulletin, 1968
The columns of Physics Bulletin have previously presented many interesting comments on the value of a PhD and the conflicting findings of Prof. Hoselitz and Prof. Conn (Physics Bulletin, February 1968, p. 53) demonstrate a need for a much deeper analysis of the position of the PhD in the context of training for British scientists and technologists.

Value-based distributions in Fortran D
1994Compiling irregular applications written in a data-parallel language, like High Performance Fortran, presents a challenging problem of growing importance. One difficulty with irregular problems is the lack of access locality when distributing data and computation naively, based on simple functions of array and iteration indices.

New Reference Values for Vitamin D
Annals of Nutrition and Metabolism, 2012In the recent past, many studies have been published on the association between vitamin D and bone health or the risk of various chronic diseases. Thus, the D-A-CH reference values [D-A-CH arises from the initial letters of the common country identification for the countries Germany (D), Austria (A) and Switzerland (CH)] for the intake of vitamin D ...

The value of physiologic vitamin D as a biomarker of dementia
Drugs of Today, 2011Vitamin D has been investigated in association with cognitive function in healthy and multimorbid elderly patients. Whether higher physiologic concentrations of vitamin D may be neuroprotective is not yet known. Epidemiological investigations have suggested a protective effect of physiologic vitamin D concentrations (circulating 25-hydroxyvitamin D) on
