During the first full school year of the Covid-19 pandemic, two central contexts for adolescent development—home and school—changed utterly. In Oregon, most middle- and high schoolers attended school entirely remotely from the beginning of the pandemic, in March, 2020, through the end of April, 2021, removing both the supports available...
Commercial fishing is a culturally and economically significant industry on the Oregon coast. The importance of this industry to human communities is often neglected in fisheries research, with economic and ecological data being favored by managers and decision makers. Recent observations in many coastal communities have indicated aging of fishermen...
A spectral fitting routine was developed to analyze X-ray emissions in neutron capture decay
processes that produce ¹⁹⁷Hg and ¹⁹⁷Pt. Through correcting for X-ray emissions, the
77.3 keV γ gamma ray intensities were analyzed. The thermal cross sections for the production of
¹⁹⁷Hg and ¹⁹⁷Pt were found to be 2088...
Massive Open Online Courses (MOOCs) have generated considerable excitement and considerable skepticism since their recent inception (e.g., Kim, 2014; Perna et al., 2014). By fall 2015, approximately 35 million people had participated in 4200 courses offered by over 550 institutions (Shah, 2015). In addition to MOOCs’ potential for expanding access...
The myxozoan Ceratonova shasta is an intestinal parasite of salmon and trout that causes ceratomyxosis, a disease characterized by severe inflammation of the intestine that can lead to hemorrhaging, necrosis, and death of the fish host. The parasite is endemic to the Pacific Northwest of the United States and Canada,...
We analyze the convergence to equilibrium of solutions to the nonlinear Berger plate evolution
equation in the presence of localized interior damping (also referred to as geometrically constrained
damping). Utilizing the results in [24], we have that any trajectory converges to the set of stationary
points N. Employing standard assumptions...
In supervised learning, label information can be provided at different levels of granularity. For small datasets, it is possible to acquire a label for each data instance. However, in the big-data regime, this fine granularity approach is prohibitively costly. For example, in semi-supervised learning, only a limited number of samples...
The amount of energy we use and the ways that we get that energy sit on the edge of dramatic change as the carbon budget which can keep the planet under 1.5C of global average temperature increase gets smaller (Allen, 2018). In response, we continue to research and develop renewable...
Dietary intake data of 15 treated patients with
phenylketonuria (PKU) (7-17 years) and six control siblings
(6-14 years) were used to evaluate the effectiveness of
medical foods to balance energy, protein, vitamin B-6, and
individual amino acids from natural foods and to evaluate
vitamin B-6 status. Four-day diet records were...
Interference with the host post-translational mechanisms, such as protein phosphorylation, is a key strategy used by many intracellular bacterial pathogens to subvert host immune cell function. Virulent non-tuberculous Mycobacteria (NTMs) unlike attenuated or non-pathogenic NTMs, successfully reside and multiply within the phagosomes of phagocytic cells such as monocytes and macrophages....
