Quantitative, Kinetic Models of Cellular Circuits
Online Presentations | 04 Apr 2009 | Contributor(s):: Michael R. Brent
Living cells contain complex, analog circuits that regulate the rate at which each gene produces its product. The kinetic properties of these circuits enable cells to respond to changes in their environments and thus to survive, reproduce, and compete. For decades, molecular biologists have been...

Aluminum: a safe, economical, high energy density material for energy storage, transport and splitting water to make hydrogen on demand
Online Presentations | 30 Mar 2009 | Contributor(s):: Jerry M. Woodall
In 1968, a team lead by the author discovered that liquid gallium saturated with aluminum at room temperature would split water into hydrogen gas, alumina and heat. More recently his current team has discovered that bulk, solid Al rich alloys will also split water in the same manner. Since 1) the...

Basic Rules of Protein Folding
Online Presentations | 31 Dec 2008 | Contributor(s):: Seth Lichter
How are proteins made? Inside cells, messenger RNA first instructs the ribosomes as to the order which amino acids should be joined together. Linked together and released from the ribosome, the protein is not functional. It now needs to fold into a precise three-dimensional shape. There are no...

Gas Damping of Microcantilevers at Low Ambient Pressures
Online Presentations | 03 Nov 2008 | Contributor(s):: Rahul Anil Bidkar
This seminar will present a theoretical model for predicting the gas damping of long, rectangular silicon microcantilevers, which are oscillating in an unbounded gaseous medium with the ambient pressures varying over 5 orders of magnitude (1000 > Kn > 0.03). The work is the result of a...

From density functional theory to defect level in silicon: Does the “band gap problem” matter?
Online Presentations | 01 Oct 2008 | Contributor(s):: Peter A. Schultz
Modeling the electrical effects of radiation damage in semiconductor devices requires a detailed description of the properties of point defects generated during and subsequent to irradiation. Such modeling requires physical parameters, such as defect electronic levels, to describe carrier...

Quantum and Thermal Effects in Nanoscale Devices
Online Presentations | 18 Sep 2008 | Contributor(s):: Dragica Vasileska
To investigate lattice heating within a Monte Carlo device simulation framework, we simultaneously solve the Boltzmann transport equation for the electrons, the 2D Poisson equation to get the self-consistent fields and the hydrodynamic equations for acoustic and optical phonons. The phonon...
