(20121203)Highfrequency wave phenomena is observed in many physical settings, most notably in acoustics, electromagnetics, and elasticity. In all of these fields, numerical simulation and modeling of the forward propagation problem ... 
Fast and accurate estimation of largescale phylogenetic alignments and trees
(20110706)Phylogenetics is the study of evolutionary relationships. Phylogenetic trees and alignments play important roles in a wide range of biological research, including reconstruction of the Tree of Life  the evolutionary ... 
Fast and accurate lithography simulation and optical proximity correction for nanometer design for manufacturing
(20091023)As semiconductor manufacture feature sizes scale into the nanometer dimension, circuit layout printability is significantly reduced due to the fundamental limit of lithography systems. This dissertation studies related ... 
Fast and accurate macromolecular solvation energy and force computations
(20100527)This thesis reports a comprehensive study of the electrostatic solvation energy computation for macromolecules. In the molecular dynamics (MD) simulations it is important to be able to compute the free energy of the ... 
Fast and accurate methods for phylogenomic analyses
(BMC Informatics, 20141215)Background: Species phylogenies are not estimated directly, but rather through phylogenetic analyses of different gene datasets. However, true gene trees can differ from the true species tree (and hence from one another) ... 
The Fast And Furious Decay Of The Peculiar Type Ic Supernova 2005Ek
We present extensive multiwavelength observations of the extremely rapidly declining Type Ic supernova (SN Ic), SN 2005ek. Reaching a peak magnitude of MR = 17.3 and decaying by similar to 3 mag in the first 15 days ... 
Fast and robust phase behavior modeling for compositional reservoir simulation
(20080829)A significant percentage of computational time in compositional simulations is spent performing flash calculations to determine the equilibrium compositions of hydrocarbon phases in situ. Flash calculations must be done ... 
A Fast Conservative Spectral Solver For The Nonlinear Boltzmann Collision Operator
(20150416)We present a conservative spectral method for the fully nonlinear Boltzmann collision operator based on the weighted convolution structure in Fourier space developed by Gamba and Tharkabhushnanam.. This method can simulate ... 
The Fast Declining Type Ia Supernova 2003Gs, And Evidence For A Significant Dispersion In NearInfrared Absolute Magnitudes Of Fast Decliners At Maximum Light
We obtained optical photometry of SN 2003gs on 49 nights, from 2 to 494 days after T(B(max)). We also obtained nearIR photometry on 21 nights. SN 2003gs was the first fast declining Type Ia SN that has been well observed ... 
Fast direct algorithms for elliptic equations via hierarchical matrix compression
(20101214)We present a fast direct algorithm for the solution of linear systems arising from elliptic equations. We extend the work of Xia et al. (2009) on combining the multifrontal method with hierarchical matrices. We offer a ...

The paper discusses the feasibility of designing and developing fast discharge down to a few milliseconds range acyclic machines as pulsepower for experiments in controlled thermonuclear fusion, such as Reference Theta ... 
Fast dynamic magnetic resonance imaging using sparse recovery methods and novel signal encoding formulations
(20160115)Magnetic resonance imaging (MRI) is a noninvasive imaging modality that provides excellent soft tissue contrast without using ionizing radiations. These qualities/properties make MRI the preferred imaging modality for ... 
Fast error detection with coverage guarantees for concurrent software
(20130508)Concurrency errors are notoriously difficult to debug because they may occur only under unexpected thread interleavings that are difficult to identify and reproduce. These errors are increasingly important as recent hardware ... 
Fast Estimator Of Primordial NonGaussianity From Temperature And Polarization Anisotropies In The Cosmic Microwave Background. II. Partial Sky Coverage And Inhomogeneous Noise
In the recent paper by Yadav and coworkers we described a fast cubic (bispectrum) estimator of the amplitude of primordial nonGaussianity of local type, f(NL), from a combined analysis of the cosmic microwave background ...
