101 Stringfellow, Gerald B.Order and surface processes in III-V semiconductor alloysSemiconductor alloys have become increasingly useful during the last four decades because, through the use of alloys, the properties of semiconductors can be tailored by varying the composition to precisely match the requirements for specific electronic and photonic devices.Semiconductor alloys; Transmission-electron-diffraction pattern; Organometallic Vaper-phase epitaxy1997
102 Christensen, Douglas A.; Andrade, Joseph D.Improved sensitivity in ellipsometry of thin biochemical films by employing sublayersEllipsometry is widely used for investigating the optical properties of thin films on planar substrates, including films of adsorbed proteins or polymers. The average thickness and effective refractive index of the adsorbed layer are calculated by measuring the A and ¥ ellipsometry parameters. Unfo...Biochemical films; SiO2 sublayer1990
103 Le Ber, Jeanne M.; Lombardo, Nancy T.; Bramble, JohnMedical students find power in their palm: PDAs in a clinical rotationLibrarians partnered with School of Medicine faculty to integrate the use of handheld devices into a third-year course.

105 Wiessner, Pauline W.On emergency decisions, egalitarianism, and group selectionBoehm (CA 37:763-93) puts forward an important thesis-that with the evolution of egalitarian societies, privileged routes to reproductive advantage are blocked and the power of individua selection severely compromised. With competition so constrained, altruistic behavior can more readily spread i...Boehm's mode; Evolution of altruistic behavior1998-06
106 Stevens, KennethAlgorithms for MIS vector generation and pruningIgnoring the effect of simultaneous switching for logic gates causes silicon failures for high performance microprocessor designs. The main reason to omit this effect is the run time penalty and potential over-conservatism. Run times are directly proportional to the vector sizes. Efficient algorithm...2006
107 Regehr, JohnInterface contracts for TinyOSTinyOS applications are built with software components that communicate through narrow interfaces. Since components enable fine-grained code reuse, this approach has been successful in creating applications that make very efficient use of the limited code and data memory on sensor network nodes. How...2007-01-01
108 Vardeny, Zeev Valentine; Raikh, Mikhail E.Anomalous coherent backscattering of light from opal photonic crystalsWe studied coherent backscattering (CBS) of light from opal photonic crystals with incomplete band gaps. We observed a dramatic broadening of the CBS cone for incident angles close to the Bragg condition in the crystals. We modify the conventional CBS theory to incorporate Bragg attenuation resultin...Coherent backscattering; Bragg condition2001-05

EPA measures the electric field-related change of the absorption in the sample as a result of above-gap illumination. An electric field leads t...Electromodulated photoinduced absorption; EPA; C60 doping; Electromodulated photoluminescence; EPL; Polaron pair polarizability1997
110 Gerig, GuidoEvaluation of DTI property maps as basis of DTI atlas buildingCompared to region of interest based DTI analysis, voxel-based analysis gives higher degree of localization and avoids the procedure of manual delineation with the resulting intra and inter-rater variability. One of the major challenges in voxel-wise DTI analysis is to get high quality voxel-level c...2010-01-01
111 Gerig, GuidoMeasures for validation of DTI tractographyThe evaluation of analysis methods for diffusion tensor imaging (DTI) remains challenging due to the lack of gold standards and validation frameworks. Significant work remains in developing metrics for comparing fiber bundles generated from streamline tractography. We propose a set of volumetric and...2012-01-01
112 Goller, FranzNonlinear model predicts diverse respiratory patterns of birdsongA central aspect of the motor control of birdsong production is the capacity to generate diverse respiratory rhythms, which determine the coarse temporal pattern of song. The neural mechanisms that underlie this diversity of respiratory gestures and the resulting acoustic syllables are largely unkn...Sound; Syllables; Song2006
113 Harrison, Reid R.Validation of adaptive threshold spike detector for neural recordingWe compare the performance of algorithms for automatic spike detection in neural recording applications. Each algorithm sets a threshold based on an estimate of the background noise level. The adaptive spike detection algorithm is suitable for implementation in analog VLSI; results from a proof-of-...Spike detection; Neural recording; Ation potential; VLSI2004-01-01
114 Myers, Chris J.Automatic abstraction for synthesis and verification of deterministic timed systemsThis paper presents a new approach for synthesis and verification of asynchronous circuits by using abstraction. It attacks the state explosion problem by avoiding the generation of a flat state space for the whole design. Instead, it breaks the design into sub-blocks and conducts synthesis and veri...2000
115 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
