We evaluated the ability of four commercial MIC testing systems (MicroScan, Vitek 2, Phoenix, and Etest) to detect vancomycin MIC values of ≤1 to ≥2 in 200 methicillin-resistant Staphylococcus aureus (MRSA) strains compared to the Clinical and Laboratory Standards Institute broth microdilution (BMD) reference methods. Compared to the BMD method, absolute agreement (0 ± dilution) was highest for...

Introduction: Phoenix showed the presence of ~1% perchlorate in the landing site regolith [1]. This ion is associated to sodium and magnesium [2], making these compounds ideal candidates for liquid brines on the surface. In addition, hydration-dehydration cycles may control the humidity. We study the stability of perchlorates (liquids and salts) under Martian conditions using a combination of e...

The Phoenix Zoo is currently housing three female wild-born Asian elephants (Elephas maximus) who came to us from other organizations with a variety of health and behavioral problems, some of which have been exasperated since arriving at our facility. Each of these elephants has had a troubled past and they were labeled as ‘problem animals’. The Phoenix Zoo, through various circumstances, acqui...

Mars is a natural laboratory for testing the physical and chemical processes that shape planetary surfaces under cold and arid climate conditions [1-3]. The Phoenix lander has discovered a wide range of chemical constituents [3-6] in samples of high latitude portions of the martian latitude-dependent mantle (LDM) [7, 8]. Critical questions remain as to whether the identified species formed in-s...

Peripherals fail. Yet, modern embedded systems largely leave the burden of tolerating peripheral failures to the programmer. This paper presents Phoenix, a semi-automated peripheral recovery system for resourceconstrained embedded systems. Phoenix introduces lightweight checkpointing mechanisms that transparently track both the internal program state and the external peripheral state. These mec...

www.sciencemag.org SCIENCE VOL 325 3 JULY 2009 5 COVER The Phoenix spacecraft on the martian polar plains (68°N latitude). The footpad at the bottom is about 1 meter below the spacecraft deck seen at the lower left. Overlaid images are trenches dug to either nearly pure water ice or ice-cemented soil. Analyses of samples taken from these trenches give clues to the history of the region. Results...

At the 1998 SPIE meeting we described a cryogenic, high-resolution spectrograph (Phoenix) for use in the 1 { 5 m region. At that time Phoenix had been used at Kitt Peak for about a year. In the intervening two years we have worked extensively with the instrument and have modiied a few aspects of the design to bring the operational characteristics more closely into agreement with the original sp...

Understanding of the functioning of urban ecosystems cannot be achieved without the data collection and modeling developed by scientists working for federal, state, and local agencies, often in cooperation with university researchers. The project engages a broad range of partners. Local government agencies include the City of Phoenix (COP), Maricopa Association of Governments (MAG) and Arizona ...

MapReduce is a programming model for data-parallel programs originally intended for data centers. MapReduce simplifies parallel programming, hiding synchronization and task management. These properties make it a promising programming model for future processors with many cores, and existing MapReduce libraries such as Phoenix have demonstrated that applications written with MapReduce perform co...
