Every cell is faced continuously with the task of transducing a vast number of external signals into appropriate intracellular responses. In mammalian cells, membrane bound receptors modulate the production of secondary messenger molecules, such as cyclic AMP (cAMP). Cell signaling through second messengers relies on the diffusion of such second...
The concept of ecosystem services broadens perspectives on nature to include not only intrinsic value but also the utilitarian value it provides to society. Viewing nature through this lens informs our understanding of how particular ecological processes benefit different actors. In this research, I examine how water utilities in the...
Machine learning applied to computer architecture has rapidly transitioned from a theoretical novelty to being a driving force behind design, control, and simulation in practically all components. These machine-learning-based methodologies are further notable for their scalability to increasingly complex design challenges, which has allowed these methodologies to surpass the prior...
The effects of N and Zn treatments on growth and nutrient composition
of sweet cherry trees were investigated in greenhouse and
outdoor sand culture experiments. In these studies, one-year old
clonal F12-1 sweet cherry trees were grown in dithizone purified
nutrient solution consisting of three levels of N (3O, 80,...
The defining feature of our planet are the oceans, which make up 70% of the Earth’s surface. The importance of the ocean cannot be understated: 50% of oxygen originates from phytoplankton; heat is absorbed and redistributed by ocean currents; and hundreds of millions of people rely on the ocean for...
After a 40-year absence from Oregon’s landscape, expanding gray wolf (Canis lupus) populations are reestablishing elements of interspecific competition with sympatric large carnivores, like cougars (Puma concolor). This presents new challenges for management of large carnivores and their ungulate prey populations (e.g., elk, Cervus canadensis nelsoni; mule deer, Odocoileus hemionus)...
Despite some successful conservation stories, biodiversity continues to be lost around the world. Climate change accentuates the ecological crisis and demands not only coordinated action by individuals and collectives, but also a re-examination (and re-imagination) of our relationship with nature. As part of the basis for such a re-examination, further...
This research examined public perceptions of risk, behavioral intentions in the event of the M9 Cascadia Subduction Zone (CSZ) earthquake and tsunami on the Oregon Coast, and factors that may influence both attitudes and intentions. A household survey was conducted to understand public opinion in Seaside, Oregon, which is located...
