We computationally explore how the orientation of dipolar emitters placed near plasmonic nanostructures affects their radiative enhancement and spontaneous emission rate. We demonstrate that the expressions for these quantities show a subtle dependence on ...
This document provides the design of an electronically reconfigurable microwave phase shifter for reflectarray systems. The phase shifter is based on a hybrid coupler with reflective circuits in three ports. Each reflective circuit introduces a phase varia ...
We present the design, synthesis, and characterization of a novel photocaged glutamine derivative (modified on the side chain of glutamine), and describe its use in enhancing peptide stability and solubility. Our results demonstrate that this approach can ...
PURPOSE: Modification of a clinical MRI scanner to enable simultaneous or rapid interleaved acquisition of signals from two different nuclei. METHODS: A device was developed to modify the local oscillator signal fed to the receive channel(s) of an MRI cons ...
Commercial buildings account for much of the energy use both in the United States and globally. The role of occupant behavior within the physical building has been found to be an important factor in the overall energy use profile of commercial buildings. R ...
Several naturally occurring vertebrate transposable elements have been genetically modified to enable the transposition of recombinant genes in mammalian cells. We compared three transposonspiggyBac, Tol2, and Sleeping Beautyfor their ability to generate c ...
Communication and environment sensing are fundamental for the regulation of the majority of the cellular functions. In cells there are dedicated networks that are responsible for signalling, which gives the ability to the cell of sensing the external and i ...
In this work the design, fabrication and characterization of silicon nitride nano-mechanical resonators is presented, starting from silicon nitride thin films deposited on Si wafers according to ten different recipes. The properties of such devices will de ...
As an advanced brain-computer interface, the flexible surface electrodearrayhas been used for spatiotemporal localization of neural interactions by recording electrocorticography (ECoG) signals over brain cortical areas. Compared with the electrical stimul ...
In this study the influence of tip leakage on the performance of a small-scale fan is evaluated through computational fluid dynamics. ANSYS CFX Release 18.1 is employed for the numerical simulations, the results are extracted, analyzed and compared to the ...
