Surface Energy Balance And Melt Thresholds Over 11 Years At Taylor Glacier, Antarctica, Matthew James Hoffman, Andrew G. Fountain, Glen E. Liston

Geography Faculty Publications and Presentations

In the McMurdo Dry Valleys, Victoria Land, Antarctica, melting of glacial ice is the primary source of water to streams, lakes, and associated ecosystems. To understand geochemical fluxes and ecological responses to past and future climates requires a physically based energy balance model. We applied a one-dimensional model to one site on Taylor Glacier using 11 years of daily meteorological data and seasonal ablation measurements. Inclusion of transmission of solar radiation into the ice was necessary to accurately model summer ablation and ice temperatures. Results showed good correspondence between calculated and measured ablation and ice temperatures over the 11 years. …

General Validity Of Reciprocity In Quantum Mechanics, P.T. Leung, H. Y. Xie, D. P. Tsai

Physics Faculty Publications and Presentations

The concept of reciprocity symmetry for matter-wave propagation is established for nonrelativistic quantum mechanics with previous results in the literature extended to include nonlocal interactions. Examples are given for cases with both local and nonlocal potentials, where we show in particular that reciprocity can be violated for the motion of a charged particle in an external electromagnetic field. In addition, this symmetry is applied to interpret a recent analysis [Phys. Rev. A 64, 042716 (2001)] on the symmetry of transmission through one-dimensional complex potentials, with the emphasis that the validity of reciprocity can go beyond that of time-reversal symmetry, such …

Greenfield, Garry Kiefer, Mai Lin, Kenneth Mcmillan, M. Isabel M. Prata, Ana C. Santos, Xiankai Sun, Jufeng Wang, Shanrong Zhang, Piyu Zhao, A. Dean Sherry

Chemistry Faculty Publications and Presentations

Objectives—Recent advances in the design of MRI contrast agents have rendered the lanthanide complexes of DOTA-tetraamide ligands of considerable interest, both as responsive MR agents and paramagnetic chemical exchange saturation transfer agents. The potential utility of these complexes for in vivo applications is contingent upon them being well tolerated by the body. The purpose of this study was to examine how the nature of the amide substituent, and in particular its charge, affected the fate of these chelates postinjection.

Materials and Methods—Complexes of 6 DOTA-tetraamide ligands were prepared in which the nature of the amide substituent was systematically …

Polymeric Paracest Agents For Enhancing Mri Contrast Sensitivity, Yunkou Wu, Youfu Zhou, Olivier Quari, Mark Woods, Piyu Zhao, Todd B. Soesbe, Garry Kiefer, A. Dean Sherry

Chemistry Faculty Publications and Presentations

Linear polymers of PARACEST agents were prepared by using classical free radical chain polymerization conditions. The Eu³⁺-polymers exhibited similar intermediate-to-slow water exchange and CEST characteristics as the Eu³⁺-monomers. This provided an avenue to lower the detection limit of these imaging agents substantially and makes them potentially useful as MRI sensors for molecular imaging.

Assessment And Refinement Of Real-Time Travel Time Algorithms For Use In Practice, Kristin A. Tufte, Sirisha Murthy Kothuri

TREC Final Reports

The Federal Highway Administration (FHWA) has set a high priority on the use of existing dynamic message signs (DMS) to provide travel time estimates to the public. The Oregon Department of Transportation (ODOT) currently has three DMS in the Portland metropolitan area configured to display travel time information. In the near future, ODOT would like to make travel time estimates available on additional DMS, over the Internet on tripcheck.com and via 511. Travel time estimates are valuable to the traveling public; however, the estimates must be accurate to be useful. The FHWA indicates that 90% accuracy is ideal and suggests …

Towards The Identification Of Lampreys (Lampetra Spp.) In Archaeological Contexts, Ross E. Smith, Virginia L. Butler

Anthropology Faculty Publications and Presentations

Lampreys were and continue to be an important resource for Native Americans in the Pacific Northwest. Lampreys possess several skeletal structures that are regularly identified in marine mammal and bird stomach contents and fecal samples, suggesting that lamprey elements may preserve in archaeological contexts. However, their remains have not been identified in archaeological faunal samples in the Pacific Northwest. This may be due to the lack of an adequate "search image" for lamprey remains among faunal analysts and limited use of line screen sampling. Descriptions and photographs of lamprey remains that are most likely to survive in archaeological contexts are …

Biomimetic Subwavelength Antireflective Gratings On Gaas, Chih-Hung Sun, Brian J. Ho, Bin Jiang, Peng Jiang

Mathematics and Statistics Faculty Publications and Presentations

We have developed a simple and scalable bottom-up approach for fabricating moth-eye antireflective coatings on GaAs substrates. Monolayer, non-close-packed silica colloidal crystals are created on crystalline GaAs wafers by a spin-coating-based single-layer reduction technique. These colloidal monolayers can be used as etching masks during a BCl_3 dry-etch process to generate subwavelength-structured antireflective gratings directly on GaAs substrates. The gratings exhibit excellent broadband antireflective properties, and the specular reflection matches with the theoretical prediction using a rigorous coupled-wave analysis model. These bioinspired antireflection coatings have important technological applications ranging from efficient solar cells to IR detectors
