A modular simulation system for the bidomain equations
Cardiac arrhythmias and fibrillation are potentially life threatening diseases that can result from the improper conduction of electrical impulses in the heart. Experimental study of such cardiac abnormalities are dangerous ... -
Charged Particle Optics Simulations and Optimizations for Miniature Mass and Energy Spectrometers
(2021)Computer simulation and modeling is a powerful tool for the analysis of physical systems; in this work we consider the use of computer modeling and optimization in improving the focusing properties of a variety of charged ... -
Configurational entropy measurements in extremely supercooled liquids that break the glass ceiling.
(Proceedings of the National Academy of Sciences of the United States of America, 2017-10-10)Liquids relax extremely slowly on approaching the glass state. One explanation is that an entropy crisis, because of the rarefaction of available states, makes it increasingly arduous to reach equilibrium in that regime. ... -
Development of a National Academic Boot Camp to Improve Fellowship Readiness.
(ATS scholar, 2020-12-22)Background: Pulmonary and critical care medicine (PCCM) fellowship requires a high degree of medical knowledge and procedural competency. Gaps in fellowship readiness can result in significant trainee anxiety related to ... -
Dipole strength in La-139 below the neutron-separation energy
(2010)The gamma-ray strength function is an important input quantity for the determination of the photoreaction rate and the neutron capture rate for astrophysics as well as for nuclear technologies. To test model predictions, ... -
Epidemic potential by sexual activity distributions.
(Netw Sci (Camb Univ Press), 2017-12)For sexually transmitted infections like HIV to propagate through a population, there must be a path linking susceptible cases to currently infectious cases. The existence of such paths depends in part on thedegree ... -
Exploration of Alkyne-bridged Multi[(Porphinato)metal] Oligomers for Charge Transport Applications and Spin-Spin Exchange Coupling Properties Using Synthetic, Spectroscopic, Potentiometric, and Magnetic Resonance Methods
(2017)As silicon-based microelectronics approaches its fundamental physical limit, molecular electronics is emerging as a promising candidate for future ultra-dense electronic devices with individual molecules as active device ... -
Investigations into the Feasibility of Optical-CT 3D Dosimetry with Minimal Use of Refractively Matched Fluids
(2014)Purpose: Optical-CT imaging with radiochromic dosimeters is a powerful method of evaluating 3D dose distributions at high resolution and sensitivity. Current optical-CT systems require large quantities of refractively ... -
Nitrogenase Electron Tunneling Pathways Analysis: From the 4Fe-4S Cluster to the P-cluster
(2018)The biological reduction of N2 to NH3 catalyzed by molybdenum nitrogenase requires eight steps to finish a completed catalysis cycle. This reaction cycle is associated with ATP-driven electron transfer (ET) from the Fe protein ... -
PSTD Method for Thermoacoustic Tomography (TAT) and Related Experimental Investigation
(2009)In this work, the simulation (forward problem) and reconstruction (inverse problem) in Thermoacoustic Tomography (TAT) are studied using a pseudospectral time-domain (PSTD) method with 4th-order time integration.The objective ... -
Rational Pessimism, Rational Exuberance, and Asset Pricing Models
(1999)estimates and examines the empirical plausibility of asset pricing models that attempt to explain features of financial markets such as the size of the equity premium and the volatility of the stock market. In one model, ... -
Superconducting Radiofrequency Probes for Magnetic Resonance Microscopy, Simulation and Experiments
(2009)In magnetic resonance microscopy, insufficient signal-to-noise ratio currently limits imaging performance. Superconducting probes can potentially increase the sensitivity of the magnetic resonance experiment. However, many ... -
