DNA methylation is common in prokaryotes and eukaryotes and has been implicated in various biological roles including gene silencing, X-chromosome inactivation, and genomic imprinting. 5-methylcytosine the "fifth base" of the genetic code comprises 1-3% of the human genome and is primarily found on cytosines within the context of the CpG...
Over the last two decades, satisfiability and satisfiability-modulo theory (SAT/SMT) solvers have grown powerful enough to be general purpose reasoning engines throughout software engineering and computer science. However, most practical use cases of SAT/SMT solvers require not just solving a single SAT/SMT problem, but solving sets of related SAT/SMT problems....
During the past two decades a wide range of intervention programs have emerged in response to escalating concerns over school bullying. The advent of such programs seems justified as 70 percent of school-aged children and youth identify bullying as a problem in their school (Polanin, et al., 2012; Renshaw &...
A mechanistic based critical heat flux (CHF) correlation has been developed derived from a mass, momentum, and energy balance at a nucleation site for water. The trigger mechanism for the CHF condition is postulated to be related to the maximum boiling frequency on a heated surface. It is observed that...
Samples of benthic organisms off the coast of Oregon, taken
from depths varying from 50 to 2900 meters, have been analyzed in
terms of diversity at a given station, and similarity and ecological
distance to other stations. Estimates of epifauna abundance were
also made. In the analysis an important distinction...
The Willamette River floodplain has been highly modified by urbanization, conversion of land to agriculture, construction of dams and revetments, and regulation of flow, all of which have reduced floodplain processes that provide valuable ecosystem services such as fish and wildlife habitat and flood storage. Efforts to protect and restore...
The study examines the acculturation and environmental adaptation of nineteenth century Chinese miners in a portion of southwestern Oregon. The problem concerns the
varieties of culture change which resulted when this ethnic group found itself required to subsist in a new social and physical environment. The study focuses on the...
Snorkel dive estimates and an inventory of stream habitat of the juvenile steelhead (Oncorhynchus mykiss) population in the Steamboat Creek basin were made in the summers of 1987 and 1988. Emigration was
monitored by fish trapping from spring through fall of 1988. Distribution, abundance, and habitat utilization of juvenile steelhead...
This work sets forth a reformulation of Levins' loop analysis for the qualitative modeling of complex dynamical systems. Relationships between members of ecological communities can be analyzed through a qualitatively specified community matrix, whereby +1, -1, or 0 represent effects of one species upon another. A contribution is made to...
