Mathematics of Ions in Channels and Solutions: Stochastic Derivations, Direct, Variational and Inverse Solutions that fit Data
05 Feb 2014 | Online Presentations | Contributor(s): Bob Eisenberg
Literally thousands of biologists study the properties of channels in experiments every day. My collaborators and I have shown how the relevant equations can be derived (almost) from stochastic differential equations, and how they can be solved in inverse, variational, and direct problems using...

IMA 2013 UQ: Prediction Interval Construction for Smart Material Systems in the Presence of Model Discrepancy
01 Apr 2014 | Online Presentations | Contributor(s): Ralph Smith
In this presentation, we will discuss issues pertaining to the construction of prediction intervals in the presence of model biases or discrepancies. We will illustrate this in the context of models for smart material systems but the issues are relevant for a range of physical and biological...
IMA 2013 UQ: Probabilistic Hazard Mapping and Uncertainty Quantification Based on Granular Flow Simulations
02 Apr 2014 | Online Presentations | Contributor(s): Elaine Spiller
PDE models of granular flows are invaluable tools for developing probabilistic hazards maps for volcanic landslides, but they are far from perfect. Epistemic uncertainty -- uncertainty due to a lack of model refinement -- arises through assumptions made in physical models, numerical...
IMA 2013 UQ: Foam Property Prediction from Process Modeling
28 May 2014 | Online Presentations
We are developing computational models to elucidate the injection, expansion, and dynamic filling process for polyurethane foam such as PMDI. The polyurethane is a chemically blown foam, where carbon dioxide is produced via reaction of water, the blowing agent, and isocyanate. In a competing...
IMA 2013 UQ: DFT-based Thermal Properties: Three Levels of Error Management
02 Apr 2014 | Online Presentations | Contributor(s): Kurt Lejaeghere
It is often computationally expensive to predict finite-temperature properties of a crystal from density-functional theory (DFT). The temperature-dependent thermal expansion coefficient α, for example, is calculated from the phonon spectrum, and the melting temperature Tm can only be obtained...
IMA 2013 UQ: Bayesian Calibration of Molecular Dynamics Simulations for Composite Materials Properties
28 May 2014 | Online Presentations | Contributor(s): Paul N. Patrone
In this talk, I discuss ongoing research whose goal is to determine, via Bayesian inference, an ensemble of inputs that represents a class of commercially important amine-cured epoxies. We construct an analytical approximation (i.e. a surrogate or emulator) of the simulations, treating the input...
Ionic Interactions in Biological and Physical Systems: a Variational Treatment
15 Feb 2014 | Online Presentations | Contributor(s): Bob Eisenberg
All biology occurs in ionic mixtures loosely called Ringer solutions. Biology depends on interactions of ions. Interactions of Na+, K+, and Ca2+ with channel proteins produce electrical signals of nerves and coordinate muscle contraction including the heart. Proteins, channels, and nucleic acids...

RF Solid-State Vibrating Transistors
15 Feb 2014 | Online Presentations | Contributor(s): Dana Weinstein
In this talk, I will discuss the Resonant Body Transistor (RBT), which can be integrated into a standard CMOS process. The first hybrid RF MEMS-CMOS resonators in Si at the transistor level of IBM’s SOI CMOS process, without any post-processing or packaging will be described. ...
Flexible Hybrid Analog and Digital Computers
11 Apr 2014 | Online Presentations | Contributor(s): Richard Wunderlich
To build the most efficient computers of the future, it is likely one will need to leverage many different computational domains depending on the problem at hand. This presentation covers reconfigurable, hybrid computers and core technologies built to explore this idea.

NEEDS Compact Model Development Process - v0.1
17 Feb 2014 | Online Presentations | Contributor(s): Michael McLennan
The Nano-Engineered Electronic Device Simulation (NEEDS) effort is focused on creating compact models for nanoelectronics. The process involves a new Berkeley Model Development Environment (MDE) tool (https://nanohub.org/tools/mde) and other infrastructure on nanoHUB.org. This seminar describes...
Probability and Time in Biological Reactions
20 Feb 2014 | Online Presentations | Contributor(s): Brian Todd
In this talk, I will describe two examples where departures from simple kinetics occur. One involves reactions that occur along DNA in the regulation of gene expression. The other is the diffusion-limited encounter dynamics for bimolecular reactions. I will also describe our progress in...
Investigating the Propagation of Optically Excited States and Optoelectronic Processes in Nano Building Block Assemblies
20 Feb 2014 | Online Presentations | Contributor(s): Alexander Weber-Bargioni
First I will present a novel approach to understand the local defect state introduced heterogeneity of local radiative charge recombination in individual InP nano wires using next generation near field optics and high resolution Kelvin Probe Microscopy. In the second part I will discuss our...
[Illinois] Designer Plasmonic Materials for Mid-Infrared Devices
18 Feb 2014 | Online Presentations | Contributor(s): Stephanie Law
The fields of plasmonics and metamaterials have seen significant growth in recent years, due to the interest in creating novel photonic devices as well as exploring the physics behind light-matter interaction at the nanoscale. Much of this work has been done in the visible spectral range with...
Theory of Heat Conduction with Type 5 Boundary Condition
19 Feb 2014 | Papers | Contributor(s): Donald E. Amos
In the classical theory, the general solution of the heat conduction problem is expressed in terms of the Green's function. Terms which take into account volumetric heat generation, an initial temperature distribution and boundary conditions can be identified. In the current literature (...
