A wideband illuminator antenna with constant effective aperture is developed for use as a calibration source for a radio telescope. Good performance is obtained over a 6:1 bandwidth.
Dual and multi-band feed systems that enable reflector antennas to operate over multiple frequency bands have been used for some time. With newer generations of satellites, there is an increased demand for these types of feeds in satellite communications. At the same time, the requirements for performance such as bandwidth and band separation are becoming increasingly challenging, leading to the development...
Candida albicans secretes aspartyl proteases (Saps) during infection. Although Saps are secretory proteins, little is known about the intracellular trafficking and secretion of these proteins. We previously cloned and analyzed the C. albicans pre-vacuolar protein sorting gene VPS4, and demonstrated that extracellular Sap2p is absent in the culture supernatants of the vps4Δ null mutant. We therefore...
To investigate the pre-vacuolar secretory pathway in Candida albicans, we cloned and analyzed the C. albicans homolog of the Saccharomyces cerevisiae vacuolar protein sorting gene VPS1. C. albicans VPS1 encodes a predicted 694-aa dynamin-like GTPase that is 73.3% similar to S. cerevisiae Vps1p. Plasmids bearing C. albicans VPS1 complemented the temperature-sensitive growth, abnormal class F vacuolar...
