The saltwater culture of a Paecilomyces cf. javanica isolated from the marine sponge Jaspis cf. coriacea has yielded a new polyketide, deoxynortrichoharzin (1), and two known diketopiperazines (2 and 3).
The history of beamforming in sonar applications goes back many years. Perhaps Collodon and Sturm’s use of a horn receiver in their 1826 measurement of the speed of sound in water is a first example. Their 13-km range certainly required a receiver with a good beam pattern to increase the signal to a measureable level. Although receivers have changed over… (More)
Multipath signals occur in many sonar, radar, and communication applications. It is, of course, generally desirable to eliminate these unwanted signals. Traditional array signal processing techniques often have trouble eliminating these signals when only a small number of array elements are available. The maximum likelihood method explicitly models multiple… (More)
