  1. Space-time constrained FOSLS with AMGe upscaling

    04 Feb 2016 | | Contributor(s):: Panayot Vassilevski

    We consider time-dependent PDEs discretized in combined space-time domains. We first reduce the PDE to a first order system. Very often in practice, one of the equations of the reduced system involves the divergence operator (in space-time). The popular FOSLS (first order system least-squares)...

  2. Multilevel Markov Chain Monte Carlo for Uncertainty Quantification in Subsurface Flow

    04 Feb 2016 | | Contributor(s):: Christian Ketelsen

    The multilevel Monte Carlo method has been shown to be an effective variance reduction technique for quantifying uncertainty in subsurface flow simulations when the random conductivity field can be represented by a simple prior distribution. In state-of-the-art subsurface simulation the...

  3. Discretization of Elliptic Differential Equations Using Sparse Grids and Prewavelets

    04 Feb 2016 | | Contributor(s):: Christoph Pflaum

    Sparse grids can be used to discretize second order elliptic differential equations on a d-dimensional cube. Using Galerkin discretization, we obtain a linear equation system with  unknowns. The corresponding discretization error is  in the -norm. A major difficulty in...

  4. High Dimensional Uncertainty Quantification via Multilevel Monte Carlo

    04 Feb 2016 | | Contributor(s):: Hillary Fairbanks

    Multilevel Monte Carlo (MLMC) has been shown to be a cost effective way to compute moments of desired quantities of interest in stochastic partial differential equations when the uncertainty in the data is high-dimensional. In this talk, we investigate the improved performance of MLMC versus...

  5. Stable Discretizations and Robust Block Preconditioners for Fluid-Structure Interaction Systems

    04 Feb 2016 | | Contributor(s):: Kai Yang

    In our work we develop a family of preconditioners for the linear algebraic systems arising from the arbitrary Lagrangian-Eulerian discretization of some fluid-structure interaction models. After the time discretization, we formulate the fluid-structure interaction equations as saddle point...

    29 Jan 2016 | | Contributor(s):: Claire Mcghee

    We aim to further improve early detection of cancer biomarkers, including metal ion and small molecules, using functional DNA as the selective component for photonic crystal surface enhanced Raman scattering (PC-SERS) based detection. It is known that gold nanoparticles (AuNPs) display SERS...

  9. [Illinois] Using Photonic Crystals to Enhance SERS Signals for Early Detection of Prostate Cancer

    29 Jan 2016 | | Contributor(s):: Caitlin Race

    Prostate cancer is the second most common cancer for men, and the second leading cause of death due to cancer in men. Currently, the most common screening method aims to detect high levels of prostate-specific antigen (PSA) in blood. Our research has shown the potential for both better prostate...

  10. [Illinois] Manipulating Substrate Topography for Enhanced Myogenic Differentiation of Primary Myoblasts and Neuromuscular Junction Formation

    29 Jan 2016 | | Contributor(s):: Eunkyung Ko

    Myogenic commitment of stem cells and primary myoblasts has drawn attention for developing treatments for skeletal muscle diseases. Biophysical cues as well as biochemical cues are known to influence the cellular mechanism of the myogenic differentiation event. Recent studies have revealed that...

  11. [Illinois] Cadherin-Modulated Neural Differentiation of Stem Cells for Neuromuscular Junction Engineering

    29 Jan 2016 | | Contributor(s):: Ellen Qin

    Recently, efforts are increasingly made to engineer NMJ in vitro for both fundamental and applied bioscience studies. Certain success was made to modulate neural differentiation of stem cells using soluble factors and cell adhesion matrix properties. However, these studies were often plagued by...

  12. [Illinois] Role for Stiffness in Vascular Fate

    29 Jan 2016 | | Contributor(s):: Lian Wong

    Stem cells, including embryonic stem cells (ESC) and induced pluripotent stem cells, have been explored as tools for studying development, as well as, potential sources for a large number of therapies in regenerative medicine. Traditionally, ESC are cultured on TC-plastic, however; it has been...

  14. [Illinois] Dimeric Trigger Responsive Drug Conjugate for High Loading Nanoencapsulates

    26 Jan 2016 | | Contributor(s):: kaimin Cai

    Polymeric micelle is one of the most widely used drug delivery nanomedicine platforms; however, micelle drug delivery systems usually have very low drug loading and poorly defined composition, which greatly limited its further clinical translation. In the course of developing trigger responsive...

  15. [Illinois] Stretch Induced Hyperexcitability of Mice Callosal Pathway

    26 Jan 2016 | | Contributor(s):: Anthony Fan

    Memory and learning are thought to result from changes in synaptic strength. Previous studies on synaptic physiology in brain slices have traditionally been focused on biochemical processes. Here, we demonstrate with experiments on mouse brain slices that central nervous system plasticity is...
