A group of 100 carefully selected chest radiographs was read by ten observers, five experienced and five inexperienced. The radiographs were chosen to present the readers with a disproportionately large number of both subtle abnormalities and nonpulmonary lesions. Each reader was allowed to search the radiographs for as long as appropriate, up to a maximum(More)
The measurement of an acoustic emission, or scatter, from a bubble is not difficult. However, an accurate interpretation of that signal in terms of the bubble dynamics may require careful consideration. The study presented here is at first sight relatively simple: comparison of the predicted and measured quality factors of injected bubbles. While the(More)

Empirical and observational data were collected from 31 sets made from a tuna purse seine vessel during the International Seafood Sustainability Foundation's (ISSF) WCPO bycatch reduction research cruise. Simultaneously, skipjack (Katsuwonis pelamis), yellowfin (Thunnus albacares), and bigeye (T. obesus) tuna and silky sharks (Carcharhinus falciformis) were(More)
Juvenile silky sharks (Carcharhinus falciformis) comprise the largest component of the incidental elasmobranch catch taken in the western and central Pacific Ocean (WCPO) tuna purse seine fishery. Population analysis for this species has shown that high mortality on the juvenile life stages has the most impact on population growth. Several aspects of the(More)
Beamforming techniques using phased microphone arrays are one of the most common tools for localizing and quantifying noise sources. However, the use of such devices can result in a series of well-known disadvantages regarding, for instance, their very high cost or transducer mismatch. Virtual Phased Arrays (VPAs) have been proposed as an alternative(More)
For the critical assessment of music recordings the uniformity of the pressure amplitude response with respect to frequency has robustly been defended as one of the principals of prime importance for any electro-acoustic monitoring system. This has been particularly so in the appraisal of the room responses, where non-linear factors such as intermodulation(More)
Empirical and observational data were collected from 45 sets made from the Cape Finisterre, a U.S. flagged tuna purse seine vessel during the International Seafood Sustainability Foundation's (ISSF) Western Central Pacific Ocean (WCPO)‐2 bycatch mitigation research cruise. Three researchers were hosted on a ride‐along style research trip and conducted(More)
