OBJECTIVE To investigate the ability of 28 blind subjects implanted with a 60-electrode Argus II (Second Sight Medical Products Inc) retinal prosthesis system to detect the direction of a moving object. METHODS Blind subjects (bare light perception or worse in both eyes) with retinitis pigmentosa were implanted with the Argus II prosthesis as part of a phase 1/2 feasibility study at multiple ...

For many species of lobsters, size at sexual maturity varies across spatially separated populations. This is so for two populations of Caribbean spiny lobster, Panulirus argus, in southern Florida, where females from open-fishing areas around the dry Tortugas mature at a larger size than females from open-fishing areas in the Florida Keys. Variations in onset of maturity between populations of ...

National Statistical Institutes (NSIs) and Market Research Bureaus conduct surveys about many different topics. To reach this aim they have developed a fully-equipped statistical production process. It is a long way from collecting raw data to publishing public information. This paper discusses one of the methodological aspects of the statistical production process. The aim of a NSI or Market R...

In 2000, a pathogenic virus was discovered in juvenile Caribbean spiny lobsters Panulirus argus from the Florida Keys, U.S.A. Panulirus argus virus 1 (PaV1) is the first naturally occurring pathogenic virus reported from lobsters, and it profoundly affects their ecology and physiology. PaV1 is widespread in the Caribbean with infections reported in Florida (U.S.A.), St. Croix, St. Kitts, Yucata...

There has been a significant amount of recent research in low-cost mechanisms for detecting errors in computer execution that are due to hardware faults. One exciting, low-cost approach to error detection is dynamic verification (sometimes also called online testing or runtime invariant checking). The idea is for the hardware to dynamically (i.e., at runtime) check whether certain necessary inv...

Panulirus argus virus 1 (PaV1) is an unclassified, pathogenic virus first discovered in Caribbean spiny lobsters Panulirus argus from the Florida Keys, USA, and has since been confirmed in lobsters in other parts of the Caribbean. Several studies have examined the prevalence, pathogenicity, and population dynamics of the pathogen in the lobster host, but little is known about the genetic divers...

A diversity of sensilla has been described in crustaceans, both across species and within a given species. However, few homologous setal types have been identified in crustaceans. In this study we examined setae with features of the hooded sensillum, which is a class of bimodal chemomechanosensilla first identified on antennules of the Caribbean spiny lobster Panulirus argus. We examined the an...

OBJECTIVE The purpose of this analysis was to compare observer-rated tasks in patients implanted with the Argus II Retinal Prosthesis System, when the device is ON versus OFF. METHODS The Functional Low-Vision Observer Rated Assessment (FLORA) instrument was administered to 26 blind patients implanted with the Argus II Retinal Prosthesis System at a mean follow-up of 36 months. FLORA is a mul...
