26 Morse, Michael DavidElectronic structure of the 4 d transition metal carbides: dispersed fluorsecence spectroscopy of MoC, RuC, and PdCDispersed fluorescence studies of the diatomic molecules MoC, RuC, and PdC are reported. New states identified in MoC and RuC are the [...]2??12??, ?,??? states and the [...]2??12??, ??? state, respectively. Five states are observed by dispersed fluorescence in PdC. The ground state is found to be [...2011
27 Hillman, Nicholas WThe ethical dimensions of awarding financial aidAbstract In countries charging tuition fees, and those that are considering adopting tuition fee policies, recent economic conditions are making education less affordable and accessible for students (Johnstone & Marcucci, 2010; Schwarzenberger & Opheim, 2009). To combat these challenges, nations, ...2011
28 Vardeny, Zeev ValentineEvidence for excimer photoexcitations in an ordered ?-conjugated polymer filmWe report pressure-dependent transient picosecond and continuous-wave photomodulation studies of disordered and ordered films of 2-methoxy-5-(2-ethylhexyloxy) poly(para-phenylenevinylene). Photoinduced absorption (PA) bands in the disordered film exhibit very weak pressure dependence and are assign...2011
29 Scarpulla, MichaelExact field solution to guided wave progagation in lossy thin filmsWave guidance is an important aspect of light trapping in thin film photovoltaics making it important to properly model the effects of loss on the field profiles. This paper derives the full-field solution for electromagnetic wave propagation in a symmetric dielectric slab with finite absorption. ...2011

The...2011
31 Kopta, Daniel M.; Kensler, Andrew Erin; Spjut, Josef Bo; Brunvand, Erik L.; Davis, AlFast, effective BVH updates for dynamic ray-traced scenes using tree rotationsBounding volume hierarchies are a popular choice for ray tracing animated scenes due to the relative simplicity of refitting bounding volumes around moving geometry. However, the quality of such a refitted tree can degrade rapidly if objects in the scene deform or rearrange significantly as the ...Ray tracing; Acceleration structures; Bounding volume hierarchies; Tree rotations; Dynamic scenes; Parallel update2011
32 Bordelon, Amanda C.Flowable fibrous concrete for thin pavement inlaysSynthetic fibers within a flowable fibrous concrete (FFC) mixture were characterized by relating their spatial distribution and orientations, determined from x-ray computed tomography (CT), with the measured toughness or fracture energy response of a FFC specimen. This new type of concrete, FFC, wa...2011
33 Paiva, MarieFrom palace to treasure house: creating a new space for the Institute of Ethiopian Studies LIbraryThe Institute of Ethiopian Studies (IES) Library is a research library located at Addis Ababa University in Ethiopia. Hope arrived in 2009 when construction began for a new IES library.Ethiopia; Research libraries; American Library Association annual conference2011
34 Scarpulla, MichaelGrain size and texture of Cu2ZnSnS4 thin films synthesized by co-sputtering binary sulfides and annealing: effects of processing conditions and sodiumWe investigate the synthesis of kesterite Cu2ZnSnS4 (CZTS) polycrystalline thin films using cosputtering from binary sulfide targets followed by annealing in sulfur vapor at 500 ?C to 650 ?C. The films are the kesterite CZTS phase as indicated by x-ray diffraction, Raman scattering, and optical abso...2011
35 D'Astous, Valerie AnneGrandparents and their grandchildren with autism spectrum disorder: building bridges through technologyAutism spectrum disorders (ASD) are neurodevelopmental disorders characterized by impaired social interactions, deficits in verbal and nonverbal communication, and repetitive behaviors or unusual or severely limited interests (American Psychiatric Association 2008). A child's autism diagnosis affect...2011
36 Armentrout, Peter B.Guided ion beam and theoretical study of the reactions of Au+ with H2, D2, and HDReactions of the late third-row transition metal cation Au+ with H2, D2, and HD are examined using guided ion beam tandem mass spectrometry. A flow tube ion source produces Au+ in its 1S (5d10) electronic ground state level. Corresponding state-specific reaction cross sections for forming AuH+ an...2011
37 Armentrout, Peter B.Guided ion beam and theoretical study of the reactions of Os + with H 2, D 2, and HDReactions of the third-row transition metal cation Os+ with H2, D2, and HD to form OsH+ (OsD+) were studied using a guided ion beam tandem mass spectrometer. A flow tube ion source produces Os+ in its 6D (6s15d6) electronic ground state level. Corresponding state-specific reaction cross sections are...2011
38 Jameson, Kenneth P.Institutions and development: what a difference geography and time makeHa-Joon Chang, in his article ?Institutions and Economic Development: Theory, Policy, and History?, provides a description and critique of the mainstream view of institutions and development. It applies well to Latin America in the 1980s and 1990s. However, the effort to introduce these Anglo-Americ...2011
39 Zhdanov, MichaelLarge-scale 3D inversion of marine magnetotelluric data: Case study from the Gemini prospect, Gulf of MexicoThree-dimensional magnetotelluric (MT) inversion is an emerging technique for offshore hydrocarbon exploration. We have developed a new approach to the 3D inversion of MT data, based on the integral equation method. The Tikhonov regularization and physical constraint have been used to obtain a stab...2011
40 Zhdanov, MichaelLarge-scale 3D inversion of potential field dataInversion of gravity and/or magnetic data attempts to recover the density and/or magnetic susceptibility distribution in a 3D earth model for subsequent geological interpretation. This is a challenging problem for a number of reasons. First, airborne gravity and magnetic surveys are characterized b...2011
41 Furse, Cynthia M.Leaky fields from damaged shieldsIn a world where wireless devices appear to dominate society, it is wires that truly rule and connect our lives. Certainly the spread of cellular phones, Bluetooth technology, wireless sensor networks, and advances of ion-lithium battery capabilities have made common daily devices more disconnecte...2011
42 Myers, Chris J.Learning genetic regulatory network connectivity from time series dataAbstract-Recent experimental advances facilitate the collection of time series data that indicate which genes in a cell are expressed. This information can be used to understand the genetic regulatory network that generates the data. Typically, Bayesian analysis approaches are applied which neglect ...2011
43 Adler, Frederick R.Mathematical model of a three-stage innate immune response to a pneumococcal lung infectionPneumococcal pneumonia is a leading cause of death and a major source of human morbidity.
