Regularity Of Digits And Significant Digits Of Random Variables, Theodore P. Hill, Klaus Schürger
Regularity Of Digits And Significant Digits Of Random Variables, Theodore P. Hill, Klaus Schürger
Research Scholars in Residence
A random variable X is digit-regular (respectively, significant-digit-regular) if the probability that every block of k given consecutive digits (significant digits) appears in the b-adic expansion of X approaches b-k as the block moves to the right, for all integers b>1 and k≥1. Necessary and sufficient conditions are established, in terms of convergence of Fourier coefficients, and in terms of convergence in distribution modulo 1, for a random variable to be digit-regular (significant-digit-regular), and basic relationships between digit-regularity and various classical classes of probability measures and normal numbers are given. These results provide a theoretical basis for analyses …
A Framework For Comparing Requirements Tracing Experiments, Jane Huffman Hayes, Alex Dekhtyar
A Framework For Comparing Requirements Tracing Experiments, Jane Huffman Hayes, Alex Dekhtyar
Computer Science and Software Engineering
The building of traceability matrices by those other than the original developers is an arduous, error prone, prolonged, and labor intensive task. Thus, after-the-fact requirements tracing is a process where the right kind of automation can definitely assist an analyst. Recently, a number of researchers have studied the application of various methods, often based on information retrieval after-the-fact tracing. The studies are diverse enough to warrant a means for comparing them easily as well as for determining areas that require further investigation. To that end, we present here an experimental framework for evaluating requirements tracing and traceability studies. Common methods, …
The Cytolethal Distending Toxin B Sub-Unit Of Helicobacter Hepaticus Is A Ca2+- And Mg2+-Dependent Neutral Nuclease, Rohana P. Dassanayake, Mark A. Griep, Gerald Duhamel
The Cytolethal Distending Toxin B Sub-Unit Of Helicobacter Hepaticus Is A Ca2+- And Mg2+-Dependent Neutral Nuclease, Rohana P. Dassanayake, Mark A. Griep, Gerald Duhamel
Mark Griep Publications
The cytolethal distending toxin B (CdtB) of the mouse pathogen Helicobacter hepaticus has cation binding and DNA catalysis residues in common with members of the mammalian deoxyribonuclease I (DNase I) family. The purpose of the present study was to characterize CdtB nuclease. To establish optimal digestion conditions and to evaluate co-factor requirements, a novel and sensitive fl uorometric assay that quantitatively determines double stranded DNA digestion was developed. Although the Ca2+- and Mg2+-dependence and neutral properties of CdtB were similar to DNase I, hydrolysis of DNA by CdtB was approximately 100-fold less active than DNase I …
The Moxee City (Washington) Mammoth: Morphostratigraphic, Taphonomic, And Taxonomic Considerations, Karl Lillquist, Steve Lundblad, Bax R. Barton
The Moxee City (Washington) Mammoth: Morphostratigraphic, Taphonomic, And Taxonomic Considerations, Karl Lillquist, Steve Lundblad, Bax R. Barton
All Faculty Scholarship for the College of the Sciences
A nearly complete, but highly fractured, proboscidean tusk was unearthed during parking lot construction near Moxee City in central Washington in May 2001. Schreger angle analysis revealed that the tusk was from a mammoth. AMS radiocarbon dating of the tusk established that the mammoth died 14,570 14C yr BP. The age, combined with the biogeography of proboscidean finds in the Pacific Northwest, suggests the tusk is from a Columbian mammoth (Mammuthus columbi). The condition of the tusk and its association with basalt and crystalline erratics suggest that a locally derived tusk was swept up in the advancing …

Penrose Conference Report: Kinematics And Geodynamics Of Intraplate Dextral Shear In Eastern California And Western Nevada, Jeffrey Lee, Daniel Stockli, Christopher Henry, Timothy Dixon
Geological Sciences Faculty Scholarship
This conference provided a forum to discuss the range of geological and geophysical datasets from the eastern California shear zone (ECSZ) and Walker Lane belt (WLB) that bear on how intraplate deformation is accommodated and how to integrate the data into a comprehensive, spatially and kinematically coherent view of intraplate deformation through time.
Informal Animation Sketching With K-Sketch, Richard Christopher Davis
Informal Animation Sketching With K-Sketch, Richard Christopher Davis
Research Collection School of Computing and Information Systems
Animation is a powerful medium that is accessible to few, because current animation tools are extremely complex. This complexity arises partially from current tools’ focus on precise, often unnecessary details and partially from the difficulty of finding a small but sufficiently powerful set of tool features. We are designing K-Sketch, an informal 2D animation tool that uses sketching and demonstration to radically reduce the time needed to create an animation. Our field studies investigating the needs of current anima-tion tool users and would-be users are helping us to mini-mize complexity by showing us how to prioritize the many possible tool …

Final Report Regional Lake Management Planning For Tmdl Development, Mark Sytsma
Center for Lakes and Reservoirs Publications and Presentations
Since the mid-1900’s, invasive aquatic weeds have been a significant problem in many of the lakes of the Clatsop Plains on the northern Oregon Coast. Weeds interfere with beneficial uses, such as boating, fishing and swimming, and have dramatically altered the chemical and biological features of the lakes. In 1994, the Oregon Department of Environmental Quality (ODEQ) added three of the lakes, Cullaby, Smith and Sunset, to the 303 (d) list of water quality impaired waters, due to the presence of the invasive aquatic weeds. ODEQ contracted with the Center for Lakes and Reservoirs and the Geology Department at PSU …
Isolation And Component Structure In Spaces Of Composition Operators, Christopher Hammond, Barbara D. Maccluer
Isolation And Component Structure In Spaces Of Composition Operators, Christopher Hammond, Barbara D. Maccluer
Mathematics Faculty Publications
We establish a condition that guarantees isolation in the space of composition operators acting between H p (B N ) and H q (B N ), for 0 < p ≤ ∞, 0 < q < ∞, and N ≥ 1. This result will allow us, in certain cases where 0 < q < p ≤ ∞, completely to characterize the component structure of this space of operators.

Light Distributions In Front Of A Circular Aperture, Evaluated Using Vector Diffraction Theory, Shekhar Guha, Glen D. Gillen
Physics
For a plane wave (having wavelength λ) incident on a circular aperture (radius a), the transverse distribution of light intensity beyond the aperture is expressed in terms of a dimensionless parameter, p1=a/λ, for various distances close to the aperture, using the vector Rayleigh-Sommerfeld diffraction theory.

Assessment Of Human Health Risks From Chemically Contaminated Lake Fishes In Greece, Eugene G. Maurakis, David V. Grimes, Dimitra Bobori, Rob Hale, Jennifer Jones
Virginia Journal of Science
Objectives were to conduct screening level surveys of locally consumed fish tissues in vicinities of two lakes (Kastoria and Pamvotis) in Greece to determine the presence of halogenated organic compounds and determine carcinogenic and non-carcinogenic human health risks associated with the consumption of sampled fish tissues. Results estimate the Incremental Lifetime Cancer Risks (ILCR) and Hazard Index (HI) values for the two local populations using site-specific population data. These results were compared to analyses conducted using U.S. Environmental Protection Agency default values in an effort to determine the applicability of USEPA default values to assessments of risks in non U.S. …
