The protein precipitates discarded during the extraction process of the Lactobacillus leichmannii vitamin B12 assay have been shown to contain significant amounts of vitamin B12. This loss of vitamin B12 provide a satisfactory explanation for many of the descrepancies between the serum vitamin B12 values obtained by the L. leichmannii method and the radio-isotopic method of Raven et al (1969). ...

Coordinated operations between unmanned air and ground assets allow leveraging of multi-domain sensing and increase opportunities for improving line of sight communications. While numerous military missions would benefit from coordinated UAV-UGV operations, foundational capabilities that integrate stove-piped tactical systems and share available sensor data are required and not yet available. i...

While some workers have studied cytochemical localizations during oogenesis in molluscs (e.g. Arvy, 1949, 1950; Bretschneider & Raven, 1951; Collier, 1960; Cowden, 1961; Pasteels & de Harven, 1963), others have examined the ultrastructure of the developing oocyte using the electron microscope (e.g. Rebhun, 1956a, b, 1961; Worley & Hershenov, 1960; Pasteels & de Harven, 1963). This work has been...

SETTING Regional hospital, Hong Kong. PARTICIPANTS Twenty-one residents who had regular in-hospital on-call duties. MAIN OUTCOME MEASURES From January to April 2002, participants were asked to comp...

With the growth of the Linked Data Web, time-efficient approaches for computing links between data sources have become indispensable. Yet, in many cases, determining the right specification for a link discovery problem is a tedious task that must still be carried out manually. We present RAVEN, an approach for the semi-automatic determination of link specifications. Our approach is based on the...

The present study investigated the relationship between age and one type of environmental factor, namely, type of school (i.e., private vs. public), and the development of mental planning ability, as measured by the Tower of London (TOL) test. Methods Participants comprised 197 public and 174 private school students, ranging in age from 4 years and 9 months to 8 years and 6 months. Besides th...

Whole genome sequencing technologies are unable to invariably read DNA molecules intact, a shortcoming that assemblers try resolve by stitching the obtained fragments back together. Here, we present methods for improvement of de novo assembly from erroneous long reads incorporated into tool called Raven. Raven maintains similar performance various genomes and has accuracy on par with other supp...
