[Illinois] Cancer Community Symposium 2012: A Sensitivity Scale for Targeting T Cells with Chimeric Antigen Receptors (CAR) and Bispecific T Cell Engagers (BiTE)
09 May 2012 | | Contributor(s):: Jennifer Stone
Using a patients immune system to target cancer and maintain long-term surveillance is an attractive goal. Although T cells can respond potently to tumors, immune tolerance mechanisms often result in deletion or inactivation of those T cells expressing specific T cell receptors (TCRs) against...
[Illinois] Cancer Community Symposium 2012: DriveRank: Discovering Patient-Specific Driver Mutations
09 May 2012 | | Contributor(s):: Jack Pu Hou
One of the pressing challenges in cancer genomics is to distinguish driver mutations (i.e. mutations involved in tumorigenesis) and passenger mutations (i.e. functionally neutral mutations). Current approaches to identifying driver mutations in cancer look for recurrent events in multiple...
[Illinois] Cancer Community Symposium 2012: Elevated Estrogen Signaling Drives Tumorigenesis in a Novel Animal Model for Ovarian Epithelial Cancer
09 May 2012 | | Contributor(s):: Mary Jo Laws
We generated a mouse model where aberrant estrogen receptor alpha (Esr1) signaling in the hypothalamo-pituitary-ovarian axis leads to ovarian tumorigenesis. In this model, termed Esr1d/d, the Esr1 gene is selectively deleted in the anterior pituitary. The Esr1d/d mice form palpable ovarian...

A Fast Multigrid Approach for Solving the Helmholtz Equation with a Point Source
04 Feb 2016 | | Contributor(s):: Eran Treister
Solving the discretized Helmholtz equations with high wave numbers in large dimensions is a challenging task. However, in many scenarios, the solution of these equations is required for a point source. In this case, the problem can be be reformulated and split into two parts: one in a solution...

In this work, we have designed and implemented a massively parallel version of the Semicoarsening Black Box Multigrid Solver , which is capable of handling highly heterogeneous and anisotropic 3D reservoirs, on a parallel architecture with multiple GPU’s. For comparison purposes, the...
A Multigrid Method for the Self-Adjoint Angular Flux Form of the Radiation-Transport Equation Based on Cellwise Block Jacobi Iteration
04 Feb 2016 | | Contributor(s):: Jeffrey Densmore
Cellwise block Jacobi iteration is a technique for radiation-transport calculations in which the angular flux for all directions is solved for simultaneously within a spatial cell with the angular flux in neighboring cells held fixed. Each step of the iteration then involves the inversion of a...
A Performance Comparison of Algebraic Multigrid Preconditioners on GPUs and MIC
04 Feb 2016 | | Contributor(s):: Karl Rupp
Algebraic multigrid (AMG) preconditioners for accelerators such as graphics processing units (GPUs) and Intel's many-integrated core (MIC) architecture typically require a careful, problem-dependent trade-off between efficient hardware use, robustness, and convergence rate in order to...
