Stimulated emission depletion (STED) microscopy and related nanoscopy techniques, which utilize a saturable optical transition between a bright and a dark state, overcome the diffraction barrier by confining one of the states to an area smaller than the Airy disk. Scanning this area across the specimen yields subdiffraction images by registering inseparable fluorescent markers sequentially in t...

Title of Dissertation: Characterizing young debris disks through far-infrared and optical observations Jessica K. Donaldson, Doctor of Philosophy, 2014 Dissertation directed by: Professor Douglas P. Hamilton Department of Astronomy University of Maryland

Periodic structures composed of quarter-wavelength or Helmholtz resonators have been widely used in the design acoustic metamaterials. An interesting phenomenon achievable through hybridization such is slow sound, which results from strong dispersion produced by local resonances. It gives rise to many applications as deep subwavelength sound absorbers metadiffusers. All proposed so far analyzed...

Two nonculture methods, in situ hybridization and immunoperoxidase staining with monoclonal antibodies, were compared for the detection of Hemophilus influenzae in 184 sputa. For in situ hybridization, a biotin-labeled probe of total genomic DNA of H influenzae type b was prepared that hybridizes specifically with H influenzae, H parainfluenzae, H hemolyticus, and H parahemolyticus DNA. Immunop...

A critical feature of the distant future is currently unresolvable uncertainty about what will then be the appropriate rate of return on capital to use for discounting. This paper shows that there is a well-defined sense in which the ‘‘lowest possible’’ interest rate should be used for discounting the far-distant future part of any investment project. Some implications are discussed for evaluat...

Within the process of plot development, authors create a complete story universe and develop the traits of its inhabitants. The inherit complexity of the story universe only adumbrates in the storyline, but it is crucial for its attractiveness and emotional impact. Interactive storytelling systems exploit the power of the author’s imagination by generating a variety of plots from a rich story u...
