This paper describes an application of classroom technology in support of teaching through the use of examples and active learning techniques. Here we report on using Classroom Presenter, a Tablet PC based classroom interaction syst, in a senior level course in Algorithms -- a domain for which the instructor believes working on sample probls is critical to(More)
Time series studies have shown that some bacterial taxa occur only at specific times of the year while others are ubiquitous in spite of seasonal shifts in environmental variables. Here, we ask if these ubiquitous clades are generalists that grow over a wide range of environmental conditions, or clusters of strain-level environmental specialists. To answer(More)
UNLABELLED There is a growing recognition of the roles of marine microenvironments as reservoirs of biodiversity and as sites of enhanced biological activity and in facilitating biological interactions. Here, we examine the bacterial community inhabiting free-living and particle-associated seawater microenvironments at the Pivers Island Coastal Observatory(More)
Phytoplankton often both provision and depend on heterotrophic bacteria. In order to investigate these relationships further, we sequenced draft genomes of three bacterial isolates from cultures of the marine diatom Thalassiosira rotula to identify metabolic functions that may support interactions with T. rotula.
In recent years, medical, industrial and military institutions have shown interest in developing small, lightweight, reliable devices to continuously monitor Heart Rate Variability (HRV) of individuals during sleep, work, exercise, or under stress. Such devices, which ideally would be no larger than a modern digital music player, would provide life-saving(More)
Marine microbes exhibit seasonal cycles in community composition, yet the key drivers of these patterns and microbial population fidelity to specific environmental conditions remain to be determined. To begin addressing these questions, we characterized microbial dynamics weekly for 3 years at a temperate, coastal site with dramatic environmental(More)
