    Dilmanian, F. Avraham; Krishnan, Sunil; McLaughlin, William E.; Lukaniec, Brendan; Baker, Jameson T.; Ailawadi, Sandeep; Hirsch, Kara N.; Cattell, Renee F.; Roy, Rahul; Helfer, Joel; Kruger, Kurt; Spuhler, Karl; He, Yulun; Tailor, Ramesh; Vassantachart, April; Heaney, Dakota C.; Zanzonico, Pat; Gobbert, Matthias K.; Graf, Jonathan S.; Nassimi, Jessica R.; Fatemi, Nasrin N.; Schweitzer, Mark E.; Bangiyev, Lev; Eley, John G. (Springer Nature Publishing AG., 2019-02-04)
    Conventional radiation therapy of brain tumors often produces cognitive deficits, particularly in children. We investigated the potential efficacy of merging Orthovoltage X-ray Minibeams (OXM). It segments the beam into ...

  • On adaptive BDDC for the flow in heterogeneous porous media 

    Sousedík, Bedřich (2019-01-07)
    We study a method based on Balancing Domain Decomposition by Constraints (BDDC) for a numerical solution of a single-phase flow in heterogenous porous media. The method solves for both flux and pressure variables. The ...
  • A Unified Approach for Solving Sequential Selection Problems 

    Goldenshluger, Alexander; Malinovsky, Yaakov; Zeevi, Assaf (2019-01-25)
    In this paper we develop a unified approach for solving a wide class of sequential selection problems. This class includes, but is not limited to, selection problems with no–information, rank–dependent rewards, and ...
  • Analyzing Two-Dimensional Gel Images

  • Protein Image Alignment via Piecewise Affine Transformations 

    Potra, Florian A.; Liu, Xing; Seillier-Moiseiwitsch, Françoise; Roy, Anindya; Hang, Yaming; Marten, Mark R.; Raman, Babu; Whisnant, Carol
    We present a new approach for aligning families of 2D gels. Instead of choosing one of the gels as reference and performing a pairwise alignment, we construct an ideal gel that is representative of the entire family and ...
  • Inexact Methods for Symmetric Stochastic Eigenvalue Problems 

    Lee, Kookjin; Sousedík, Bedřich (2018-11-02)
    We study two inexact methods for solutions of random eigenvalue problems in the context of spectral stochastic finite elements. In particular, given a parameter-dependent, symmetric matrix operator, the methods solve for ...
  • Cross-cancer Prediction: A Novel Machine Learning Approach to Discover Molecular Targets for Development of Treatments for Multiple Cancers 

    Gao, Katie; Wang, Dayong; Huang, Yi (SAGE journals, 2018-10-22)
    Conventional cancer drug development has long been limited to organ- or tissue-specific cancer types. However, it has become increasingly known that specific genetic abnormalities are responsible for the carcinogenesis of ...
  • Least Sparsity of p-Norm Based Optimization Problems with p>1* 

    Shen, Jinglai; Mousavi, Seyedahmad (Society for Industrial and Applied Mathematics, 2018-09-27)
    Motivated by lp-optimization arising from sparse optimization, high-dimensional data analytics and statistics, this paper studies sparse properties of a wide range of p-norm based optimization problems with p > 1, including ...
  • A parallel simulation of the evolution of transcription factor binding sites 

    Forder, Robert (2011-05-27)
    The analysis of transcription factor binding motifs may aid in understanding the process by which transcription factors recognize their binding sites. We wish to investigate the likelihood that transcription factors use ...
  • Water Quality Monitoring of Maryland’s Tidal Waterways 

    Le, Rosemary K.; Rackauckas, Christopher V.; Ross, Anne S.; Ulloa, Nehemias (2012)
    The Chesapeake Bay and its surrounding tributaries are home to over 3,600 species of plants and animals. In order to assess the health of the region, the Maryland Department of Natural Resources (DNR) monitors various ...
  • Validation of a Model of a Resonant Optothermoacoustic Trace Gas Sensor 

    Petra, N.; Zweck, J.; Minkoff, S. E.; Kosterev, A. A.; Doty, J. H. (OSA, 2011-06)
    A model for a resonant optothermoacoustic sensor is validated by comparison with experiments performed with 0.5% acetylene in nitrogen. At low concentrations, the molecular dynamics of the trace gas do not influence the signal.
  • Numerical and Experimental Investigation for a Resonant Optothermoacoustic Sensor 

    Petra, N.; Kosterev, A. A.; Zweck, J.; Minkoff, S. E.; Doty, J. H. (IEEE, 2010-07-01)
    A theoretical study of a resonant optothermoacoustic sensor employing a laser source and a quartz tuning fork receiver validates experimental results showing that the source should be positioned near the base of the receiver.

    Yang, Shiming; Gobbert, Matthias K. (Elsevier Ltd, 2009-03-24)
    The finite difference discretization of the Poisson equation with Dirichlet boundary conditions leads to a large, sparse system of linear equations for the solution values at the interior mesh points. This problem is a ...
  • The Influence of Stochastic Parameters on Calcium Waves in a Heart Cell
