Cultivated peanut (Arachis hypogaea) is an allotetraploid species whose ancestral genomes are most likely derived from the A-genome species, A. duranensis, and the B-genome species, A. ipaensis. The very recent (several millennia) evolutionary origin of A. hypogaea has imposed a bottleneck for allelic and phenotypic diversity within the cultigen. However,… (More)
Neural stem/progenitor cell (NSPC) transplantation is a promising therapy for spinal cord injury (SCI). However, little is known about NSPC from the adult human spinal cord as a donor source. We demonstrate for the first time that multipotent and self-renewing NSPC can be cultured, passaged and transplanted from the adult human spinal cord of organ… (More)
A protection measure based on a simple model of a protection system is presented. The measure shows how closely a computer system adheres to the principle of minimum privilege. Its application to the operating system of the Cambridge University CAP computer is described and ways of bringing the operating system closer to a state of minimum privilege are… (More)
One approach advocated in the search for better designed and more reliable operating systems is to base the design on the use of small protection domains. This paper presents empirical evidence to show that, with a suitable architecture, the overheads associated with using small protection domains do not make this an impractical approach.

Previous vocal fold modeling studies have generally focused on generating detailed data regarding a narrow subset of possible model configurations. These studies can be interpreted to be the investigation of a single subject under one or more vocal conditions. In this study, a broad population-based sensitivity analysis is employed to examine the behavior… (More)
OBJECTIVES Collagen fiber content and orientation affect the viscoelastic properties of the vocal folds, determining oscillation characteristics during speech and other vocalization. The investigation and reconstruction of the collagen network in vocal folds remains a challenge, because the collagen network requires at least micron-scale resolution. In this… (More)
