We describe an approach to optical non-reciprocity that exploits the local helicity of evanescent electric fields in axisymmetric resonators. By interfacing an optical cavity to helicity-sensitive transitions, such as Zeeman levels in a quantum dot, light transmission through a waveguide becomes direction-dependent when the state degeneracy is lifted. Using a...
Nitrogen (N) deposition can alter belowground microbial communities, especially ectomycorrhizal (ECM) fungi, resulting in a reduced ability of associated trees to access organic nutrients. This study tested whether N addition decreases ECM species richness and shifts ECM species composition across spatial scales in a subtropical slash pine (Pinus elliottii) plantation...
Behind the Wallpaper was written for Julia Holter and Spektral Quartet in 2014–15, expanding on a four-song cycle of the same name from 2013. It was premiered on February 23, 2015 at Amsterdam Bar & Hall in St. Paul, MN, as part of the Liquid Music Series. The piece tells...
This document gives a brief history of classical music (Western art music) in Sarajevo, Bosnia and Herzegovina, with a focus on recent events and developments from the beginning of the siege (1992) to the present. Further focus is placed on the effects of Sarajevo's cultural pluralism on the city's largest...
In recent years, research has expanded the uses of triblock copolymer gels to a wide variety of applications including everything from ceramics processing to regenerative medicine and drug delivery. The research presented in this dissertation focuses on a physically crosslinked, block copolymers gel system in a selective solvent. This system...
Background: Current upper limb prostheses do not replace the active degrees-of-freedom distal to the elbow inherent to intact physiology. Limited evidence suggests that transradial prosthesis users demonstrate shoulder and trunk movements to compensate for these missing volitional degrees-of-freedom. The purpose of this study was to enhance understanding of the effects...
Assembly of the large and small subunits of the <em>E. coli</em> ribosome is a complicated process that involves transcription, processing, and modifying of the ribosomal RNA, the binding of ribosomal proteins, and the folding of the particles into complex structures. A number of ribosome assembly factors, including maturation factors, GTPases,...
Cell state transitions are often triggered by large changes in the
concentrations of transcription factors and therefore large differences
in their stoichiometric ratios. Whether cells can elicit transitions using
modest changes in the ratios of co-expressed factors is unclear. Here,
we investigate how cells in the Drosophila eye resolve state...
