Elephant seals migrate over vast areas of the eastern North Pacific Ocean between rookeries in Southern California and distant northern foraging areas. Several models of particle movement were evaluated and a model for great circle motion found to give reasonable results for the movement of an adult female. This model takes specific account of the fact that the movement is on the surface of a s...

BACKGROUND Geographical accessibility is important in accessing healthcare services. Measuring it has evolved alongside technological and data analysis advances. High correlations between different methods have been detected, but no comparisons exist in the context of palliative and end of life care (PEoLC) studies. To assess how geographical accessibility can affect PEoLC, selection of an appr...

In this paper we introduce a two-step Certified Reduced Basis (RB) method. In the first step we construct from an expensive finite element “truth” discretization of dimension N an intermediate RB model of dimension N N . In the second step we construct from this intermediate RB model a derived RB (DRB) model of dimension M ≤ N . The construction of the DRB model is effected at cost O(N) and in ...

What does ‘mosquito specialist’ mean? A mosquito specialist is a predator that actively prefers mosquitoes, by which we mean that it is differentially motivated to capture mosquitoes among possible prey. This would make it extraordinarily useful, as it would be targeting an insect that matters to people. At best, the mosquito is a nuisance and, at worst, it is a notorious disease vector. There ...

Background & Aims: Radiology reports are often the only means of communication between radiologists and physicians. Despite the importance of these reports, practically physicians do not give a feedback about radiology reports. This study was aimed to determine the opinions of specialists towards radiology reports. Methods: in this descriptive study, sample consisted of all specialists working ...
