An empirical examination of respondent driven sampling design effects among HIV risk groups from studies conducted around the world
(Springer, 2013)
For studies using respondent driven sampling (RDS), the current practice of collecting a sample twice as large as that used in simple random sampling (SRS) (i.e. design effect of 2.00) may not be sufficient. This paper ...
Numerical simulations of the current channeling effect on MT responses due to shallow conductive structures
(Elsevier Science, 2003-12)
MT data obtained at an alluvial valley in Argentina showed a strong telluric current channeling along its axis. This effect was reflected in the MT curves as a very low response for the TM apparent resistivity for periods ...
Root hydraulic conductance, aquaporins and plant growth promoting microorganisms: A revision
(Elsevier Science, 2012-10)
A considerable number of soil and rhizospheric fungi and bacteria collectively known as plant growth promoting microorganisms (PGPM) have demonstrated ability to colonize plant roots and to provide benefits to their hosts. ...
Conductance through strongly interacting rings in a magnetic field
(Elsevier Science, 2009-08)
We study the conductance through finite Aharonov-Bohm rings of interacting electrons weakly coupled to non-interacting leads at two arbitrary sites. This model can describe an array of quantum dots with a large charging ...
Explicit estimates versus numerical bounds for the electrical conductivity of dispersions with dissimilar particle shape and distribution
(Springer, 2020-08-01)
An effective-medium theory for the electrical conductivity of Ohmic dispersions taking explicit account of particle shape and spatial distribution independently is available from the work of Ponte Castañeda and Willis [J ...
Lipid hydroperoxidation effect on the dynamical evolution of the conductance process in bilayer lipid membranes: A condition toward criticality
(American Chemical Society, 2020-08-04)
Cell membranes are one of the main targets of oxidative processes mediated by reactive oxygen species (ROS). These chemical species interact with unsaturated fatty acids of membrane lipids, triggering an autocatalytic chain ...
Asymmetrical external effects on transmission, conductance and giant tunneling magnetoresistance in silicene
(Elsevier, 2018-01)
Electron transport in a silicene structure, composed of a pair of magnetic gates, is studied
in a ferromagnetic and antiferromagnetic configuration. The transport properties are
investigated for asymmetrical external ...
Adaptive Boundary Control Using Natural Switching Surfaces for Flyback Converters Operating in the Boundary Conduction Mode with Parameter Uncertainties
(Institute of Electrical and Electronics Engineers, 2019-08)
The derivation and implementation of the natural switching surfaces (NSS) considering certain parametric uncertainties for a flyback converter operating in the boundary conduction mode is the main focus of this paper. The ...
Evaluation of the spreading thermal resistance for rough spheres
(Pergamon-Elsevier Science Ltd, 2015-07)
The solid-solid contact of rough spherical particles in packed beds takes place by the deformation of individual asperities that transmit the stresses to the main body of the particles. This causes an elastically deformed ...
