A lov Story: A role for jim lovell in Drosophila neural development and fertility.
(2011)A forward genetic screen looking for altered gravity response identified the gene jim lovell (lov). This gene is related to the gene fruitless, which specifies male courtship ii behavior in Drosophila. Like fruitless, ... 
A lowenergy, electronspinpolarized helium(+) ion source for use in surface studies
(1998)A spin polarized He$\sp+$ ion source has been developed to study the dynamics of ionsurface interactions. The He$\sp+$ ions are produced by Penning ionization in collisions between electronspinpolarized He(2$\sp3$S) ... 
A magnetic potential model for the interface of verticalfield taillobes with Venus' nightside ionosphere
(1998)Venus' nightside ionosphere may be characterized by two general magnetic field geometries. Most of the ionosphere is characterized by largely horizontal fields carried over across the terminator from the dayside. However, ... 
A magnetospheric magnetic field model with flexible internal current systems
(1989)A three dimensional Bfield model of the Earth's magnetosphere satisfying the condition $\nabla$ $\cdot$ B = 0 is described. Highly flexible ring and crosstail current systems are combined with the vacuum Bfield model ... 
A mantle xenolith window into the Grenville orogeny of Southern Laurentia
(2009)The nature of the lithospheric mantle beneath orogenic belts is incompletely understood due to the paucity of mantle xenolithbearing basaltic magmas in such regions. One such place where we are afforded the opportunity ... 
A map of life: An epistemological study of the Human Genome Project
(1999)Based on research primarily conducted in a molecular biology laboratory working on the Human Genome Project (HGP), this dissertation focusesupon how genomic research, as an emerging form of scientific knowledge, stands ... 
A mathematical model of the afferent stage of the mammalian baroreceptor reflex
(1994)The purpose of this research effort is to develop a mathematical model of the afferent portion mammalian arterial baroreceptor reflex. The entire model is comprised of a small network of HodgkinHuxley (HH) type membrane ... 
A mathematical model of the amphibian muscarinic channel
(1989)A modification of the OsterriederNomaTrautwein model of the AChsensitive K$\sp+$ I$\sb{K,ACh}$ current in the rabbit SA node is used to study the behavior of the AChsensitive K$\sp+$ channels in bullfrog atrial and ... 
A mathematical model of the mammalian ventricular cell: Mechanistic explanations of long QT syndrome
(2002)We have developed a mathematical model of a rabbit ventricular cell based on available whole cell voltage clamp data. The model consists of three components: a HodgkinHuxley type membrane model describing the electrical ... 
A MATHEMATICAL PROGRAMMING MODEL FOR AGRICULTURE SECTOR POLICY ANALYSIS
(1984)A price endogenous, spatial equilibrium mathematical programming model (USMP) is formulated and applied to address contemporary issues in U.S. agriculture sector policy. The historical and theoretical development of this ... 
A Matlab implementation of the Implicitly Restarted Arnoldi Method for solving largescale eigenvalue problems
(1996)This thesis describes a Matlab implementation of the Implicitly Restarted Arnoldi Method for computing a few selected eigenvalues of large structured matrices. Shiftandinvert methods allow the calculation of the eigenvalues ... 
A Matter of Perspective: Reliable Communication and Coping with Interference with Only Local Views
(20120905)This dissertation studies interference in wireless networks. Interference results from multiple simultaneous attempts to communicate, often between unassociated sources and receivers, preventing extensive coordination. ...
