Controlling Electromagnetic Surface Waves with Scalar and Tensor Impedance Surfaces.
(2013)
The propagation characteristics of electromagnetic waves on various isotropic (scalar) impedance surfaces have been studied for some time, in order to control surface waves and leaky-wave radiation. One and two dimensional ...
Development of a Time-Resolved Laser-Induced Fluorescence Technique for Nonperiodic Oscillations
(2016)
Time-resolved measurements of ion dynamics could be key to understanding the physics of instabilities, electron transport, and erosion in Hall thrusters. Traditional measurements of the ion velocity distribution in Hall ...
Gender Differences in the Behavioral Responses to Cocaine and Amphetamine
(Blackwell Publishing Ltd, 2001-06)
When ovariectomized female rats receive estrogen, the response to the psychomotor stimulants amphetamine or cocaine is enhanced. Estrous cycle-dependent differences in amphetamine-stimulated behaviors and striatal dopamine ...
A Fourth Order Scheme for Incompressible Boussinesq Equations
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 2003-04)
A fourth order finite difference method is presented for the 2D unsteady viscous incompressible Boussinesq equations in vorticity-stream function formulation. The method is especially suitable for moderate to large Reynolds ...
Fishes of the Mio-Pliocene Western Snake River Plain and Vicinity.
(2018-07-31)
Hybridization and introgression permitted gene transfer from Catostomus to Lake Suckers in modern and MioPliocene lakes of Western United States. Lake Sucker genera, Chasmistes, Deltistes, and Xyrauchen, were sympatric ...
Demographic Stochasticity in Evolutionary Biology.
(2013)
Demographic stochasticity, the random fluctuations arising from the intrinsic discreteness of populations and the uncertainty of individual birth and death events, is an essential feature of population dynamics. Nevertheless ...
Osteology of the southwestern darters, Ethostoma (Oligocephalus) (Teleostei, Percidae) - with comparison to other North American percid fishes
(University of Michigan Museum of Zoology, 2001)
Analysis of inquiry materials to explain complexity of chemical reasoning in physical chemistry students’ argumentation
(Springer, Science and Technology Education LibraryWiley Periodicals, Inc., 2017-12)
One aim of inquiry activities in science education is to promote students’ participation in the practices used to build scientific knowledge by providing opportunities to engage in scientific discourse. However, many factors ...
Interpreting the Paradoxical in the Hispanic Paradox
(Blackwell Publishing Ltd, 2001-12)
This paper discusses problems that are common to both the epidemiologic risk-factor approach and the demographic variable-based approach to studying population health. We argue that there is a shared reluctance to move ...
Characterization of A. baumannii Environmental Survival and Biofilm Formation and the Impact on Environmental Transmission.
(2015)
Acinetobacter baumannii is a gram-negative, opportunistic pathogen primarily affecting the critically ill, causing 3% of all nosocomial-related deaths in the United States. A. baumannii’s successful environmental survival ...
