Mutations that abolish expression of an X-linked gene, FMR1, result in the pathogenesis of fragile X syndrome, the most common form of inherited mental retardation. To understand the normal function of the FMR1 protein, we have produced fly strains bearing deletions in a Drosophila homolog of FMR1 (dfmr1). Since fragile X patients show a number of abnormal(More)
Terahertz pulses trapped as surface waves on a wire waveguide can be flexibly transmitted and focused to sub-wavelength dimensions by using, for example, a tapered tip. This is particularly useful for applications that require high-field pulses. However, the generation of strong terahertz surface waves on a wire waveguide remains a challenge. Here,(More)
