1 Pascucci, ValerioExploring power behaviors and trade-offs of in-situ data analyticsAs scientific applications target exascale, challenges related to data and energy are becoming dominating concerns. For example, coupled simulation workflows are increasingly adopting in-situ data processing and analysis techniques to address costs and overheads due to data movement and I/O. However...2013-01-01
2 Seyedhosseini Tarzjani, Seyed MojtabaImage segmentation with cascaded hierarchical models and logistic disjunctive normal networksContextual 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
3 Gur, YanivAssessment of white matter microstructure in stroke patients using NODDIDiffusion weighted imaging (DWI) is widely used to study changes in white matter following stroke. In various studies employing diffusion tensor imaging (DTI) and high angular resolution diffusion imaging (HARDI) modalities, it has been shown that fractional anisotropy (FA), me...2014-01-01
4 Pascucci, ValerioCharacterization and modeling of PIDX parallel I/O for performance optimizationParallel I/O library performance can vary greatly in re- sponse to user-tunable parameter values such as aggregator count, file count, and aggregation strategy. Unfortunately, manual selection of these values is time consuming and dependent on characteristics of the target machine, the underlying fi...2013-01-01
5 Gerig, GuidoEfficient probabilistic and geometric anatomical mapping using particle mesh approximation on GPUsDeformable image registration in the presence of considerable contrast differences and large size and shape changes presents significant research challenges. First, it requires a robust registration framework that does not depend on intensity measurements and can handle large nonlinear shape variati...2011-01-01
6 Gerig, GuidoA preliminary study on the effect of motion correction on HARDI reconstructionPost-acquisition motion correction is widely performed in diffusion-weighted imaging (DWI) to guarantee voxel-wise correspondence between DWIs. Whereas this is primarily motivated to save as many scans as possible if corrupted by motion, users do not fully understand the consequences of different ty...2014-01-01
7 Gerig, Guido3D tensor normalization for improved accuracy in DTI tensor registration methodsThis paper presents a method for normalization of diffusion tensor images (DTI) to a xed DTI template, a pre-processing step to improve the performance of full tensor based registration methods. The proposed method maps the individual tensors of the subject image in to the template space based on ma...2012-01-01
8 Planelles, VicenteAn HIV-encoded antisense long non-coding RNA epigenetically regulates viral transcriptionThe abundance of long non-coding RNAs (lncRNAs) and their wide range of functional roles in human cells are fast becoming realized. Importantly, lncRNAs have been identified as epigenetic modulators and consequently play a pivotal role in the regulation of gene expression. A human immunodeficiency v...2014-01-01
9 Meyer, Miriah DawnDesign activity framework for visualization designAn important aspect in visualization design is the connection between what a designer does and the decisions the designer makes. Existing design process models, however, do not explicitly link back to models for visualization design decisions. We bridge this gap by introducing the design activity fr...2014-01-01
10 Gerig, GuidoAbnormal vessel tortuosity as a marker of treatment response of malignant gliomas: preliminary reportDespite multiple advances in medical imaging, noninvasive monitoring of therapeutic efficacy for malignant gliomas remains problematic. An underutilized observation is that malignancy induces characteristic abnormalities of vessel shape. These characteristic shape abnormalities affect both capillari...2004-01-01
11 Anderson, Erik WesleyDiscovering and visualizing patterns in EEG dataBrain 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
12 Gerig, GuidoDiffusion tensor imaging: application to the study of the developing brainObjective: To provide an overview of diffusion tensor imaging (DTI) and its application to the study of white matter in the developing brain, in both healthy and clinical samples. Method: The development of DTI and its application to brain imaging of white matter tracts is discussed. 48 studies usi...2007-01-01
