A theory is developed to provide an analytical solution to an
unsteady flow field which is partially occupied by a porous structure.
The flow is induced by a small amplitude incident wave
train. The porous structure may contain multi-layer anisotropic but
homogeneous media. Three typical porous structures are investigated:
a...
The Rattlesnake Ash-Flow Tuff erupted 7.05±0.01 Ma from the western Harney Basin, southeastern Oregon. The location of the vent area is inferred based on vent-ward increases in size of pumices, in degree of welding, and in degree of post-emplacement crystallization. Today's outcrops cover 9000 km2 and estimated original outcrop coverage...
Chromosome segregation relies on coordinated activity of a large assembly of proteins, the kinetochore interaction network (KIN). How conserved the underlying mechanisms driving the epigenetic phenomenon of centromere and kinetochore assembly and maintenance are remains unclear, even though various eukaryotic models have been studied. More than 50 different proteins, many...
Neptunium, with its rich redox chemistry, has a special position in the chemistry of actinides. With a decades-long history of development of aqueous separation methods for used nuclear fuel (UNF), management of neptunium remains an unresolved issue because of its not clearly defined redox speciation. Neptunium is present in two,...
Used Nuclear Fuel (UNF) contains transuranic (TRU) elements and numerous fission products as a result of the uranium fission process and neutron activation that occur in commercial light water power reactors. Recent environmental and nuclear proliferation concerns have spawned the development of advanced reprocessing techniques to close the nuclear fuel...
Terahertz (THz) spectroscopy is a great tool not only to study fundamental physical processes such as many-body Coulomb interaction but also to develop ultrafast electronic devices. More specifically, intense THz fields interacting with semiconductors have exhibited strong nonlinear effect involving extreme carrier dynamics. In this experiment, intense THz radiation was...

The magnitude of the effect on decay heat of neutron
capture by fission products for hypothesized "worst case"
irradiations was examined. This effect is shown to be
small (less than 2 percent) for times less than 1,000
seconds and a simple model is presented for estimating
the magnitude of the...
In eukaryotes, the defined loci on each chromosome, the centromeres, accomplish
the critical task of correct cell division. In some organisms, centromeres are
composed of a euchromatic central core region embedded in a stretch of
heterochromatin and the inheritance and maintenance of centromeres are controlled
by dynamic epigenetic phenomena. Although...
Fire history and fire regime were interpreted from tree ring analysis of 4320 stumps at 178 sites in a 25 by 55 km area in the central Oregon Coast Range. A total of 27 fire episodes were identified in a 516 year period, with sizes estimated at 18 to 544...
Riparian forests in the Idaho Panhandle, north of Whitebird, were surveyed for rare riparian lichen species. The region was stratified into nine geographic units and by stream size. Eighty-one plots were surveyed for lichen community, stand and river characteristics. Variables important to lichen community composition included regional differences, elevation, climatic...
We consider computational modeling of flow with small and large velocities at
porescale and at corescale, and we address various challenges in simulation, upscaling, and modeling.
While our focus is on voxel-based data sets from real porous media imaging, our methodology is
verified first on synthetic geometries, and we analyze...
Ever-increasing size, complexity and operation costs in modern
power systems have stimulated the intensive study of an optimal
Load Shedding and Generator Rescheduling (LSGR) strategy in the
sense of a secure and economic system operation.
The conventional approach to LSGR has been based on the application of LP (Linear Programming)...
In introducing the method of electrical images we first consider
the elementary problem of finding the electric field of a single point
charge and an infinite conducting plane. Then a problem involving a
conducting sphere and an exterior point charge is investigated and
the results are applied in the solution...
The purpose of this thesis is to construct several stochastic
process models for combined statistical dynamic prediction of the
500-millibar pressure surface for the northern hemisphere. To
achieve this, a random forcing function is added to the spectral form
of the nondivergent vorticity equation. Three models, one linear and
two...
If P is an integer polynomial denote the degree of P by ∂(P) and let H(P) be the maximum of the absolute value of the coefficients of P. Define Λ(P)=2[superscript ∂(P)]H(P) and for a fixed prime p let C[subscript p] denote the completion of the algebraic closure of the p-adic...
Background: Like other transformative healthcare initiatives, patient-centered medical home (PCMH) implementation requires substantial investments of time and resources. Even though PCMH and PCMH-like models are being implemented by multiple provider practices and health systems, little is known about what facilitates their implementation. The purpose of this study was to assess...

Most metal ions have negative impacts on pulp mill operations. The concentrations of metal ions on pulp fibers and in washwaters rise significantly with increased wastewater recycling. The development of technology to remove these metal ions requires an understanding of how metal ions are bound to pulp components. It is...
Effective separation of lanthanides (Ln) from the minor actinides (MA) is a crucial technical challenge to closing the nuclear fuel cycle. This separation is a necessary prerequisite to transmute long-lived isotopes of Am and Cm, which will allow a reduction of the repository volume, thermal load, and radiological toxicity of...
Here we present the first downcore results for a new paleoproxy, the Mn/Ca ratio of foraminiferal calcite, applied to sediment accumulated in the extreme Eastern Tropical North Pacific (ETNP) over the last 30,000 years. The Mn/Ca results are compared to oxygen isotopes and sea surface temperature calculated from Mg/Ca. We...
A theory of higher order connections is developed as
a reduction of the structure group of the jet bundle of
sections of a smooth vector bundle. This definition leads
naturally to higher order curvatures and covariant derivatives.
Curvature Conditions for a second order partial differential

DNA is often described as the “blueprint for life”. In eukaryotes this information is contained within linear chromosomes of varying size and number. During cell division, the chromosomes must be faithfully segregated into each daughter cell to avoid disease and sustain life. This process is carried out by the kinetochore...

The extent of biological invasions, their role on the feeding of
native fishes and their impact on community stability were
investigated in Alsea Bay and Yaquina Bay, two estuaries on the
central Oregon coast, USA. Most nonindigenous species (NIS)
introduced in these intermediately invaded estuaries are
considered byproducts of culturing...
The next generation of nuclear safety analysis computer codes will include detailed modeling of the interfacial area concentration. The interfacial area concentration is the essence of the two-fluid model. It is the most accurate of the two-phase models since it considers each phase independently and links the two phases together...
The kernel subtraction method of Kantorovich and Krylov is
studied in the setting of "Collectively Compact Operator Approximation
Theory." Fredholm integral equations of the second kind have
weakly singular kernels smoothened by a simple manipulation. This
allows for accurate numerical estimates of low order. The method
is first explained in...
An algorithm is described for determining the vertices
and supporting planes (or lines) of the convex hull
of a given set of N distinct points in 3-space. The
method involves determining a finite sequence of convex
hulls, each successive convex hull being a better approximation
to the convex hull of...
There are a number of well known techniques for extracting parallelism from a given program. They range from hardware implementations, building restructuring compilers or reorganizing of programs so as to specify all the available parallelism. The success rate of any of the known techniques is rather poor over all types...
A method for the synthesis of bilateral networks is
presented. A new algorithm for the realization of basic
