Pygmy rabbits (Brachylagus idahoensis) in Oregon and Washington are a sagebrush (Artemisia tridentata spp.) obligate species of concern because of declining populations and extirpation from much of their range. Efforts are underway to establish a captive bred population of the Columbia Basin pygmy rabbit in Washington state for reintroduction into...
It is important to avoid misallocation of resources for either
private or public production. Misallocation in public programs
can result from failure to employ resources in h:igh priority uses
or to eliminate programs that have become obsolete. This study
evaluates the benefits and costs of the continuing public program
aimed...
The goal of many machine learning problems can be formalized as the creation of a function that can properly classify an input vector, given a set of examples of that function. While this formalism has produced a number of success stories, there are notable situations in which it fails. One...
Intravenous regional limb perfusion (IVRLP) with tiludronate is a commonly used treatment for distal limb orthopedic disease in horses, but doses and protocols are anecdotal. IVRLP exposes articular cartilage within the perfused area to tiludronate, raising concerns about safety of this treatment, as high tiludronate concentrations (≥19mg/L) were harmful for...
Lingcod (Ophiodon elongatus) are known to utilize certain estuaries along the Pacific coast of the United States, but the importance of these habitats to the coast-wide population is not well understood. In this study, general patterns of estuarine habitat use were assessed by tracking the movement of sub-adult and adult...
Ubiquitous pathogen Pseudomonas aeruginosa coordinates population-wide activation of virulence genes through quorum sensing (QS), where individuals transition from solo to social behaviors to benefit the population. QS is complex and mechanisms vary from species to species, but the concept is common to the bacterial world and has implications in various...
Black men who have sex with men (BMSM) experience among the highest rates of HIV infection in the United States. We conducted a community-based ethnography in New York City to identify the structural and environmental factors that influence BMSMs vulnerability to HIV and their engagement with HIV prevention services. Methods...
Depleted species of rockfish (Sebastes spp.) from the Northeast Pacific experience high discard mortality due to "barotrauma," induced from the rapid change in pressure during capture. Research suggests rockfish have the potential to survive barotrauma if immediately recompressed, but the potential for long-term recovery is unknown. In this project, we...

In 2014, W. Bogley identified a relation between the algebraic and geometric prop- erties of cyclically presented groups Gn (w) in the case where w = x0xkxl is a positive word of length three. Specifically, it was shown that the dynamics of the shift θG on the group G =...
