301 Couldwell, William T.Norman Dott, Gerard Guiot, and Jules Hardy: key players in the resurrection of transsphenoidal surgeryDeveloped over a century ago, the introduction of the transsphenoidal approach to access lesions of the pituitary gland and sella turcica has transformed the field of neurosurgery, largely due to the work of Oskar Hirsch and Harvey Cushing. Furthermore, its use and modification in the early 1900s wa...2012-01-01
302 Wunderlich, Adam JamesOn efficient assessment of image-quality metrics based on linear model observersThis paper is motivated by the problem of image-quality assessment using model observers for the purpose of development and optimization of medical imaging systems. Specifically, we present a study regarding the estimation of the receiver operating characteristic (ROC) curve for the observer and ass...2012-01-01
303 Jones, Bryan W.Online parameter estimation in dynamic Markov Random Fields for image sequence analysisMarkov Random Fields (MRF) have proven to be extremely useful models for efficient and accurate image segmentation.Recent literature points to an increased effort towards incorporating useful priors (shape, geometry, context) in a MRF framework. However, topological priors, considered extremely cruc...2012-01-01
304 Blair, StevenOptical antenna design for fluorescence enhancement in the ultravioletThrough rational design, we compare the performance of three plasmonic antenna structures for UV fluorescence enhancement. Among the antenna performance metrics considered are the local increase in excitation intensity and the increase in quantum efficiency, the product of which represents the net f...2012-01-01
305 Sudan, KshitijOptimizing datacenter power with memory system levers for guaranteed quality-of-serviceCo-location of applications is a proven technique to improve hardware utilization. Recent advances in virtualization have made co-location of independent applications on shared hardware a common scenario in datacenters. Colocation, while maintaining Quality-of-Service (QoS) for each application is a...2012-01-01
306 Khan, Faisal HabibOutput impedance modeling of a multilevel modular switched-capacitor converter to achieve continuously variable conversion ratioThe multilevel modular capacitor clamped dc-to-dc converter (MMCCC) topology is completely modular and belongs to two-phase switched capacitor converter group. The conversion ratio of an ideal MMCCC converter in step-up mode is an integer and depends on the number of modules used. For a k-module MMC...2012-01-01
307 Pascucci, ValerioThe parallel computation of morse-smale complexesTopology-based techniques are useful for multi-scale exploration of the feature space of scalar-valued functions, such as those derived from the output of large-scale simulations. The Morse-Smale (MS) complex, in particular, allows robust identification of gradient-based features, and therefore is s...2012-01-01
308 Gopalakrishnan, GaneshParameterized verification of GPU kernel programsWe present an automated symbolic verifier for checking the functional correctness of GPGPU kernels parametrically, for an arbitrary number of threads. Our tool PUG checks the functional equivalence of a kernel and its optimized versions, helping debug errors introduced during memory coalescing and b...2012-01-01
309 Utz, Rebecca L.Parental divorce among young and adult children: a long-term quantitative analysis of mental health and family solidarityIn 2008, it was estimated that 40 percent of all marriages ended in divorce (U.S. Census, 2004) . Research has long suggested that the consequences of divorce can be profound for the children of divorced families (Amato, 2000). For example, children who experienced parental divorce were 50 percent m...2012-01-01
310 Kesner, Raymond P.Parietal lesions produce illusory conjunction errors in ratsWhen several different objects are presented, visual objects are perceived correctly only if their features are identified and then bound together. Illusory-conjunction errors result When an object is correctly identified but is combined incorrectly. The parietal cortex (PC) has been shown repeatedl...2012-01-01
311 Gerig, GuidoPatient-tailored connectomics visualization for the assessment of white matter atrophy in traumatic brain injuryAvailable approaches to the investigation of traumatic brain injury (TBI) are frequently hampered, to some extent, by the unsatisfactory abilities of existing methodologies to efficiently define and represent affected structural connectivity and functional mechanisms underlying TI-related pathology....2012-01-01
312 Saam, BrianPhase relationship between the long-time beats of free induction decays and spin echoes in solidsRecent theoretical work on the role of microscopic chaos in the dynamics and relaxation of many-body quantum systems has made several experimentally confirmed predictions about the systems of interacting nuclear spins in solids, focusing in particular on the shapes of spin echo responses measured by...2012-01-01
313 Vardeny, Zeev ValentinePhotoexcitation dynamics in polythiophene/fullerene blends for photovoltaic applicationsWe used the transient and steady state photomodulation spectroscopies for studying the photoexcitations dynamics in blends of regio-regular poly(3-hexylthiophene) (RR-P3HT) and fullerene in a broad spectral range from 0.15 to 2.25 eV. We found that both localized polarons and singlet excitons are in...2012-01-01
314 Hannon, James C.Physical activity differences by birthplace and sex in youth of Mexican HeritageBackground: One of the goals of Healthy People 2020 is to increase physical activity (PA) and reduce health disparities among different racial and ethnic segments of the U.S. population. Few studies have been conducted to examine PA differences by birthplace and sex in youth of Mexican heritage. Met...2012-01-01
315 Rieth, Loren WPlasma-assisted atomic layer deposition of Al2O3 and parylene C bi-layer encapsulation for chronic implantable electronicsEncapsulation of biomedical implants with complex three dimensional geometries is one of the greatest challenges achieving long-term functionality and stability.
