Dannhauer, Moritz | Visualizing simulated electrical fields from electroencephalography and transcranial electric brain stimulation: a comparative evaluation | Electrical activity of neuronal populations is a crucial aspect of brain activity. This activity is not measured directly but recorded as electrical potential changes using head surface electrodes (electroencephalogram - EEG). Head surface electrodes can also be deployed to inject electrical current... | | 2014-01-01 |

Kendall, Katherine | Quality of life scores compared to objective measures of swallowing function after oropharyngeal chemoradiation | Objectives: To compare objective measures of swallowing function with patient reports of swallowing-related Quality of Life one year after treatment of oropharyngeal cancer with chemoradiation therapy. Study Design: Patients seen for follow-up at least one year after treatment of oropharyngeal carci... | | 2014-01-01 |

Sanderson, Allen Reed | An alternative formulation of lyapunov exponents for computing lagrangian coherent structures | Lagrangian coherent structures are time-evolving surfaces that highlight areas in flow fields where neighboring advected particles diverge or converge. The detection and understanding of such structures is an important part of many applications such as in oceanography where there is a need to predic... | | 2014-01-01 |

Rosen, Paul Andrew | 2D vector field simplification based on robustness | Vector field simplification aims to reduce the complexity of the flow by removing features in order of their relevance and importance, to reveal prominent behavior and obtain a compact representation for interpretation. Most existing simplification techniques based on the topological skeleton succes... | | 2014-01-01 |

Macleod, Robert S. | Identification and acute targeting of gaps in atrial ablation lesion sets using a real-time magnetic resonance imaging system | Background-Radiofrequency ablation is routinely used to treat cardiac arrhythmias, but gaps remain in ablation lesion sets because there is no direct visualization of ablation-related changes. In this study, we acutely identify and target gaps using a real-time magnetic resonance imaging (RT-MRI) sy... | | 2012-01-01 |

Seyedhosseini Tarzjani, Seyed Mojtaba | Image segmentation with cascaded hierarchical models and logistic disjunctive normal networks | Contextual information plays an important role in solving vision problems such as image segmentation. However, extracting contextual information and using it in an effective way remains a difficult problem. To address this challenge, we propose a multi-resolution contextual framework, called cascade... | | 2013-01-01 |

Farrell, Timothy W. | Organizational culture associated with provider satisfaction | Background: Organizational culture is key to the successful implementation of major improvement strategies. Transformation to a patient-centered medical home (PCHM) is such an improvement strategy, requiring a shift from provider-centric care to team-based care. Because this shift may impact provide... | | 2014-01-01 |

Gur, Yaniv | Graph diffusion distance: a difference measure for weighted graphs based on the graph Laplacian exponential kernel | We propose a novel difference metric, called the graph diffusion distance (GDD), for quantifying the difference between two weighted graphs with the same number of vertices. Our approach is based on measuring the average similarity of heat diffusion on each graph. We compute the graph Laplacian expo... | | 2013-01-01 |

Harris, Michael D. | Correlations between the alpha angle and femoral head asphericity: Implications and recommendations for the diagnosis of cam femoroacetabular impingement | Objective: To determine the strength of common radiographic and radial CT views for measuring true femoral head asphericity. Patients and Methods: In 15 patients with cam femoroacetabular impingement (FAI) and 15 controls, alpha angles were measured by two observers using radial CT (0º, 30º, 60º,... | | 2014-01-01 |

Gerig, Guido | Multi-atlas segmentation of subcortical brain structures via the AutoSeg software pipeline | Automated segmenting and labeling of individual brain anatomical regions, in MRI are challenging, due to the issue of individual structural variability. Although atlas-based segmentation has show its potential for both tissue and structure segmentation, due to the inherent natural variability as wel... | | 2014-01-01 |

Anderson, Erik Wesley | Discovering and visualizing patterns in EEG data | Brain activity data is often collected through the use of electroen-cephalography (EEG). In this data acquisition modality, the electric fields generated by neurons are measured at the scalp. Although this technology is capable of measuring activity from a group of neurons, recent efforts provide ev... | | 2013-01-01 |

Kuhlman, Brian | PHD Entrepreneur | The idea for this speech began when my friends and family started asking what I would do after graduating with my PhD in psychology. Folks tended to get a bit confused when I replied that my plan is to start a business. You don't need a PhD to do that! It's true. The path leading from PhD to Entrepr... | entrepreneur; PhD; doctoral; industry; academia | 2013-05-03 |

Wunderlich, Adam James | A nonparametric procedure for comparing the areas under correlated LROC curves | In contrast to the receiver operating characteristic (ROC) assessment paradigm, localization ROC (LROC) analysis provides a means to jointly assess the accuracy of localization and detection in an observer study. In a typical multireader, multicase (MRMC) evaluation, the data sets are paired so that... | | 2012-01-01 |

Solomon, Douglas Kip | Bayesian evaluation of groundwater age distribution using radioactive tracers and anthropogenic chemicals | The development of a Bayesian modeling approach for estimation of the age distribution of groundwater using radioactive isotopes and anthropogenic chemicals is described. The model considers the uncertainties associated with the measured tracer concentrations as well as the parameters affecting the ... | | 2012-01-01 |

Wunderlich, Adam James | On efficient assessment of image-quality metrics based on linear model observers | This 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 |
