101 Gerig, GuidoGroup mean differences of voxel and surface objects via nonlinear averagingBuilding of atlases representing average and variability of a population of images or of segmented objects is a key topic in application areas like brain mapping, deformable object segmentation and object classification. Recent developments in image averaging, i.e. constructing an image which is cen...2006-01-01
102 Francis, LeslieGroup compromise: perfect cases make problematic generalizationsRothstein argues that groups may be harmed by research on deidentified data. He concludes that researchers are obligated to minimize group harms and demonstrate respect for a studied group through robust opt-out capacities, information about the possibility of group-based harms, and publications ref...2010-01-01
103 Armentrout, Peter B.Infrared multiple photon dissociation spectroscopy of protonated histidine and 4-phenyl imidazoleThe gas-phase structures of protonated histidine (His) and the side-chain model, protonated 4-phenyl imidazole (PhIm), are examined by infrared multiple photon dissociation (IRMPD) action spectroscopy utilizing light generated by the free electron laser FELIX. To identify the structures present in t...2012-01-01
104 Regehr, JohnInferring scheduling behavior with hourglassAlthough computer programs explicitly represent data values, time values are usually implicit. This makes it difficult to analyze and debug real-time programs whose correctness depends partially on the time at which results are computed. This paper shows how to use Hourglass, an instrumented, synthe...2002-01-01
105 Blumenthal, Donald K.In vivo evaluation of the delivery and efficacy of a sirolimus-laden polymer gel for inhibition of hyperplasia in a porcine model of arteriovenous hemodialysis graft stenosisSynthetic arteriovenous (AV) hemodialysis grafts are plagued by hyperplasia resulting in occlusion and graft failure yet there are no clinically available preventative treatments.

106 Frederick, Jeanne M.Inactivity of human β,β-carotene-9′, 10-′dioxygenase (BCO2) underlies retinal accumulation of the human macular carotenoid pigmentThe macula of the primate retina uniquely concentrates high amounts of the xanthophyll carotenoids lutein, zeaxanthin, and meso-zeaxanthin, but the underlying biochemical mechanisms for this spatial- and species-specific localization have not been fully elucidated. For example, despite abundant reti...2014-01-01
107 Mitchell, Joyce A.Integrating historical clinical and financial data for pharmacological researchBackground: Retrospective research requires longitudinal data, and repositories derived from electronic health records (EHR) can be sources of such data.

108 Wittwer, Carl T.Influence of PCR reagents on DNA polymerase extension rates measured on real-time PCR instrumentsBACKGROUND: Radioactive DNA polymerase activity methods are cumbersome and do not provide initial extension rates. A simple extension rate assay would enable study of basic assumptions about PCR and define the limits of rapid PCR. METHODS: A continuous assay that monitors DNA polymerase extension us...2014-01-01
109 Forster, Richard R.Initial in situ measurements of perennial meltwater storage in the Greenland firn aquiferA perennial storage of water in a firn aquifer was discovered in southeast Greenland in 2011. We present the first in situ measurements of the aquifer, including densities and temperatures. Water was present at depths between ~12 and 37m and amounted to 18.7 ± 0.9 kg in the extracted core. The wate...2014-01-01
110 Minteer, Shelley D.In recognition of Adam Heller and his enduring contributions to electrochemistryRecent progress in diverse scientific fields ranging from bioelectrochemistry to battery technology to photoconversion has been deeply influenced by the contributions of Professor Adam Heller of the University of Texas at Austin to electrochemistry and materials science. This focus issue recognizes ...2014-01-01
111 Regehr, JohnMemory safety and untrusted extensions for TinyOSSensor network applications should be reliable. However, TinyOS, the dominant sensor net OS, lacks basic building blocks for reliable software systems: memory protection, isolation, and safe termination. These features are typically found in general-purpose operating systems but are believed to be t...2006-01-01
112 Balasubramonian, RajeevMemZip: exploring unconventional benefits from memory compressionMemory compression has been proposed and deployed in the past to grow the capacity of a memory system and reduce page fault rates. Compression also has secondary benefits: it can reduce energy and bandwidth demands. However, most prior mechanisms have been designed to focus on the capacity metric an...2014-01-01
113 Jameson, Kenneth P.Measuring the effect of Bi-directional migration remittances on poverty and inequality in NicaraguaThis paper examines the impact of migrants' remittances on poverty and income distribution in Nicaragua. Nicaraguan emigrants are fairly evenly distributed between the United States and Costa Rica. Poorer migrants overwhelmingly migrate to Costa Rica; richer migrants favor the United States. This bi...2011-01-01
114 Sekercioglu, CaganMeasuring the meltdown: drivers of global amphibian extinction and declineHabitat loss, climate change, over-exploitation, disease and other factors have been hypothesised in the global decline of amphibian biodiversity. However, the relative importance of and synergies among different drivers are still poorly understood. We present the largest global analysis of roughly ...2008-01-01
115 Lupton, John MarkMechanisms of spin-dependent dark conductivity in films of a soluble fullerene derivative under bipolar injectionWe report room-temperature pulsed electrically detected magnetic resonance measurements of the dark conductivity of films of the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM) under bipolar (electron-hole) and unipolar (electron-rich) injection conditions.
