We describe a three dimensional front tracking algorithm, discuss its numerical implementation, and present studies to validate the correctness of this approach. Based on the results of the two dimensional computations, we expect three dimensional front tracking to improve signiicantly computational eeciencies for problems dominated by discontinu-ities. In some cases, for which the interface co...

Fusion at the front eurite extension is dependent on the growing neurite's ability to get longer rather than fatter. Sakisaka et al. (page 17) now show that a protein called tomosyn works in a complex to help focus membrane growth to the tip of growing neurites. As neurites grow, traveling vesicles are prevented from fusing willy-nilly to the plasma membrane first by their attachment to microtu...

Although educational attainment and physical activity levels tend to be positively associated in majority populations, this relationship has not been investigated in American Indian and Alaska Native (AI/AN) elders. This study examined the association between education and physical activity among AI/AN elders (N = 107) using self-report and behavioral outcomes. Regression models showed that hig...

HAVING written a book on the British Army’s use of horses from 1875 to 1925 (Winton 2013), I read with great interest the feature article by C. Trenton Boyd and Bruce Vivash Jones, ‘Postcards from the Front’ (VR, February 21, 2015, vol 176, pp 192-194). The postcard collection was quite amazing. There are, however, a number of points made in the article on which I would make comment. One might ...

The integrated Rule Oriented Data Management System (iRODS) is a policy-driven data management system that is starting to be used by projects with large data volume requirements that require a highly available system. In this paper we describe an approach to provide a Highly Availability load-balanced iRODS System (HAIRS). We also describe the advantages and disadvantages of the approach and fu...

Background There is strong evidence supporting that pharmacist involvement strengthens the quality of the medication process. There is also evidence indicating that many emergency admissions among the elderly are medicine related. Based on this existing knowledge, it was decided to investigate whether implementation of clinical pharmacy in the Emergency Department could make a further difference.
