  • Nguyen, Hien M.; Sutton, Bradley P.; Morrison, Robert L., Jr.; Do, Minh N. (Institute of Electrical and Electronics Engineers, 2009-02)
    Magnetic resonance imaging (MRI) uses applied spatial variations in the magnetic field to encode spatial position. Therefore, nonuniformities in the main magnetic field can cause image distortions. In order to correct the ...
  • Venkataraman, Archana; Rathi, Yogesh; Kubicki, Marek; Westin, Carl-Fredrik; Golland, Polina (Springer Berlin / Heidelberg, 2010-09)
    We propose a novel probabilistic framework to merge information from DWI tractography and resting-state fMRI correlations. In particular, we model the interaction of latent anatomical and functional connectivity templates ...
  • van der Hilst, Robert D.; Liu, Qi-Yuan; Yu, Li; Chen, Jiu-Hui; Guo, Biao; Wang, Jun; Qi, Shao-Hua; Li, Shun-Cheng (Chinese Geophysical Society (CGS), 2010-11)
    In this study, we present a method for the joint inversion of receiver function and ambient noise based on Bayesian inverse theory (Tarantola, 1987, 2005). The nonlinear inversion method of the complex spectrum ratio of ...
  • Dutta, Partha; Mhatre, Vivek; Rastogi, Rajeev; Panigrahi, Debmalya (Institute of Electrical and Electronics Engineers (IEEE), 2010-05)
    Long-distance multi-hop wireless networks have been used in recent years to provide connectivity to rural areas. The salient features of such networks include TDMA channel access, nodes with multiple radios, and point-to-point ...
  • Traskov, Danail; Medard, Muriel; Sadeghi, Parastoo; Koetter, Ralf (Institute of Electrical and Electronics Engineers, 2009-11)
    We consider a wireless multi-hop network and design an algorithm for jointly optimal scheduling of packet transmissions and network coding. We consider network coding across different users, however with the restriction ...
  • Raviv, Tammy Riklin; Van Leemput, Koen; Wells, William M.; Golland, Polina (Springer Berlin / Heidelberg, 2009-10)
    Spatial priors, such as probabilistic atlases, play an important role in MRI segmentation. However, the availability of comprehensive, reliable and suitable manual segmentations for atlas construction is limited. We therefore ...
  • Ahmadi, Amir Ali; Parrilo, Pablo A.; Roozbehani, Mardavij; Jungers, Raphael M. (Society for Industrial and Applied Mathematics, 2014-02)
    We introduce the framework of path-complete graph Lyapunov functions for approximation of the joint spectral radius. The approach is based on the analysis of the underlying switched system via inequalities imposed among ...
  • Didyk, Piotr; Sitthi-Amorn, Pitchaya; Freeman, William T.; Durand, Fredo; Matusik, Wojciech (Association for Computing Machinery, 2013-11)
    Multi-view autostereoscopic displays provide an immersive, glasses-free 3D viewing experience, but they require correctly filtered content from multiple viewpoints. This, however, cannot be easily obtained with current ...
  • Zamir, Ram; Kochman, Yuval (Institute of Electrical and Electronics Engineers, 2009-10)
    The combination of source coding with decoder side information (the Wyner-Ziv problem) and channel coding with encoder side information (the Gel'fand-Pinsker problem) can be optimally solved using the separation principle. ...
  • Lippert, Ross A.; Strang, W. Gilbert (International Linear Algebra Society, 2009-06)
    The relationship between the Jordan forms of the matrix products AB and BA for some given A and B was first described by Harley Flanders in 1951. Their non-zero eigenvalues and non-singular Jordan structures are the same, ...
  • Autor, David H. (American Economic Association, 2012-05)
    When I was a graduate student, I discovered that the Journal of Economic Perspectives embodied much of what I love about the field of economics: the clarity that pierces rhetoric to seek the core of a question; the rigor ...
  • Paschke, Adrian; Zhao, Jun; Samwald, Matthias; Marshall, M. Scott; Frost, H. Robert; Cheung, Kei-Hoi; Prud'hommeaux, Eric Gordon (BioMed Central, 2009-10)
    Background: As interest in adopting the Semantic Web in the biomedical domain continues to grow, Semantic Web technology has been evolving and maturing. A variety of technological approaches including triplestore technologies, ...
  • Konopliv, Alex S.; Park, Ryan S.; Yuan, Dah-Ning; Asmar, Sami W.; Watkins, Michael M.; Williams, James G.; Fahnestock, Eugene; Kruizinga, Gerhard; Paik, Meegyeong; Strekalov, Dmitry; Harvey, Nate; Smith, David Edmund; Zuber, Maria (American Geophysical Union, 2013-07)
    The lunar gravity field and topography provide a way to probe the interior structure of the Moon. Prior to the Gravity Recovery and Interior Laboratory (GRAIL) mission, knowledge of the lunar gravity was limited mostly to ...
  • Walker, Matthew H.; Sakuma, Tai; Redwine, Robert P.; Milner, Richard G.; Leight, William Axel; Kocoloski, Adam Philip; Jones, Christopher LaDon; Hoffman, A. M.; Corliss, Ross Cameron; Betancourt, Michael Joseph; Surrow, Bernd; Balewski, Jan T. (American Physical Society, 2009-10)
    The STAR Collaboration at the Relativistic Heavy Ion Collider presents measurements of J/psi-->e+e- at midrapidity and high transverse momentum (pT>5 GeV/c) in p+p and central Cu+Cu collisions at [sqrt]sNN=200 GeV. The ...
  • Rice, Mabel L.; Hoffman, Lesa (American Speech-Language-Hearing Association, 2009-12)
    Purpose: Clinical grammar markers are needed for children with SLI older than 8 years. This study followed children who were previously studied on sentences with omitted finiteness to determine if affected children continue ...
  • Shim, Keun Sup; Lis, Mieszko; Khan, Omer; Devadas, Srinivas (2012-01)
    Chip-multiprocessors (CMPs) have become the mainstream chip design in recent years; for scalability reasons, designs with high core counts tend towards tiled CMPs with physically distributed shared caches. This naturally ...
  • Miljkovic, Nenad; Preston, Daniel John; Enright, Ryan; Adera, Solomon E.; Nam, Youngsuk; Wang, Evelyn N. (American Society of Mechanical Engineers, 2013-07)
    Environmental scanning electron microscope (ESEM) and high speed images of coalescence-induced droplet jumping on a nanostructured superhydrophobic copper oxide (CuO) surface are presented. Nanostructured CuO films were ...
  • Miljkovic, Nenad; Preston, Daniel John; Enright, Ryan; Wang, Evelyn N. (American Institute of Physics, 2014-06-19)
    Micro- and nanoscale wetting phenomena has been an active area of research due to its potential for improving engineered system performance involving phase change. With the recent advancements in micro/nanofabrication ...
  • Miljkovic, Nenad; Enright, Ryan; Nam, Youngsuk; Lopez, Ken; Dou, Nicholas; Sack, Jean H.; Wang, Evelyn N. (American Chemical Society, 2012-11)
    When droplets coalesce on a superhydrophobic nanostructured surface, the resulting droplet can jump from the surface due to the release of excess surface energy. If designed properly, these superhydrophobic nanostructured ...
  • Bonawitz, Elizabeth; Saxe, Rebecca R.; Gopnik, Alison; Meltzoff, Andrew N.; Woodward, James; Schulz, Laura E.; Ferranti, Darlene (Elsevier, 2010-12)
    Adults’ causal representations integrate information about predictive relations and the possibility of effective intervention; if one event reliably predicts another, adults can represent the possibility that acting to ...
