226 Gerig, GuidoParametric regression scheme for distributions: analysis of DTI fiber tract diffusion changes in early Brain DevelopmentTemporal modeling frameworks often operate on scalar variables by summarizing data at initial stages as statistical summaries of the underlying distributions. For instance, DTI analysis often employs summary statistics, like mean, for regions of interest and properties along fiber tracts for populat...2014-01-01
227 Erickson, J. AlanPatient-specific instrumentation in total knee arthroplasty provides no improvement in component alignmentImproved component alignment in TKA remains a commonly cited benefit of MRI based patient-specific instrumentation (PSI). We hypothesized that PSI would lead to improved alignment versus traditional instrumentation (TI) during primary TKA. Fifty-eight knees (54 patients) that underwent TKA with PSI...2014-01-01
228 Ehleringer, James R.Patterns of local and nonlocal water resource use across the western U.S. determined via stable isotope intercomparisonsIn the western U.S., the mismatch between public water demands and natural water availability necessitates large interbasin transfers of water as well as groundwater mining of fossil aquifers. Here we identify probable situations of nonlocal water use in both space and time based on isotopic compari...2014-01-01
229 Rockwood, Alan L.Performance enhancement in the measurement of 5 endogenous steroids by LC-MS/MS combined with differential ion mobility spectrometryBackground: Challenges for steroid analysis by LC-MS/MS include low ionization efficiency, endogenous isobars with similar fragmentation patterns and chromatographic retention.

231 Bohs, Lynn A.Phylogeny of the carolinense clade of solanum (Solanaceae) inferred from nuclear and plastid DNA sequencesThe large and economically important genus Solanum contains ca. 1,400 species distributed worldwide. One of the 12-14 major clades identified in the genus is the Leptostemonum clade, or the "spiny solanums." Previous molecular phylogenetic studies have identified 14 major clades in the spiny solanum...2014-01-01
232 Wen, MingPhysical activity and mortality among middle-aged and older adults in the United StatesBackground-Physical activity (PA) has been routinely linked to lower all-cause mortality, yet extant research in the United States is primarily based on non-representative samples. Evidence is scant on the relative and independent merits of leisure-time (LTPA) versus non-leisure-time (NLTPA) activit...2014-01-01
233 Brown, Barbara B.Physical activity mediates the relationship between perceived crime safety and obesityObjective. The current cross-sectional study tests whether low perceived crime safety is associated with body mass index (BMI) and obesity risk and whether less moderate-to-vigorous physical activity (MVPA) accounts for part of this relationship. Method. Adults (n=864) from a relatively low-income a...2014-01-01
234 Eddings, Eric G.The potential of on-line optical flow measurement in the control and monitoring of pilot-scale oxy-coal flamesDigital image processing techniques oer a wide array of tools capable of extracting apparent displacement or velocity information from sequences of images of moving objects. Optical flow algorithms have been widely used in areas such as traffic monitoring and surveillance. The knowledge of instantan...2014-01-01
235 Bromley, Benjamin C.Predicted space motions for hypervelocity and runaway stars: proper motions and radial velocities for the GAIA EraWe predict the distinctive three dimensional space motions of hypervelocity stars (HVSs) and runaway stars moving in a realistic Galactic potential. For nearby stars with distances less than 10 kpc, unbound stars are rare; proper motions alone rarely isolate bound HVSs and runaways from indigenous h...2014-01-01
236 Poulter, Charles DalePredicting the functions and specificity of triterpenoid synthases: a mechanism-based multi-intermediate docking approachTerpenoid synthases construct the carbon skeletons of tens of thousands of natural products. To predict functions and specificity of triterpenoid synthases, a mechanism-based, multi-intermediate docking approach is proposed. In addition to enzyme function prediction, other potential applications of ...2014-01-01
237 Liu, FengPrediction of a Dirac state in monolayer TiB2We predict the existence of a Dirac state in a monolayer TiB2 sheet (m-TiB2), a two-dimensionalmetal diboride, based on first-principles calculations. The band structure of m-TiB2 is found to be characterized with anisotropic Dirac cones with the largest Fermi velocity of 0.57 × 106 m/s, which is a...2014-01-01
238 Sutherland, James ClaytonPrediction of oxy-coal flame stand-off using high-fidelity thermochemical models and the one-dimensional turbulence modelAn Eulerian one-dimensional turbulence (ODT) model is applied to simulate oxy-coal combustion, with specific aim at predicting flame stand-o distances. Detailed gas-phase chemical kinetics based on the GRI3.0 mechanism are utilized. A high-fidelity model for devolatilization is considered that predi...2014-01-01
239 Forster, Richard R.Prevalence of pure versus mixed snow cover pixels across spatial resolutions in alpine environmentsRemote sensing of snow-covered area (SCA) can be binary (indicating the presence/absence of snow cover at each pixel) or fractional (indicating the fraction of each pixel covered by snow). Fractional SCA mapping provides more information than binary SCA, but is more difficult to implement and may no...2014-01-01
240 Millgram, ElijahPrivate persons and minimal personsIt's a commonplace that privacy can now be abridged and abdicated in ways that weren't routinely possible until very recently. I want here to draw attention to an alternative configuration of the mind that these techniques make available, which I will call the minimal person. My explication of minim...2014-01-01
