Volume mixing and isotope ratios secured with repeated atmospheric measurements taken with the Sample Analysis at Mars instrument suite on the Curiosity rover are: carbon dioxide (CO2), 0.960(±0.007); argon-40 ((40)Ar), 0.0193(±0.0001); nitrogen (N2), 0.0189(±0.0003); oxygen, 1.45(±0.09) × 10(-3); carbon monoxide, < 1.0 × 10(-3); and (40)Ar/(36)Ar,(More)
We present the rst detection of NH3 ice in the thermal infrared in Jupiter’s atmosphere using Cassini CIRS observations in the 10m region obtained on 31 December 2000 and 1 January 2001. We identify a brightness temperature di;erence ≡ TB(1040 cm−1) − TB(1060 cm−1) as an indicator of spectrally identi able NH3 ice, where 1040 cm−1 is an adjacent continuum(More)
Resource utilization in High Performance Compute clusters can be improved by increased awareness of system state information. Sophisticated run-time characterization of system state in increasingly large clusters requires a scalable fault-tolerant RAS framework. In this paper we describe the architecture of OVIS-2 and how it meets these requirements. We(More)
Although Pteris vittata L. and Sedum alfredii Hance have been identified as an As hyperaccumulator and a Zn/Cd hyperaccumulator, respectively, for a few years, variations in metal accumulation among populations and their arbuscular mycorrhizal (AM) status have not been fully explored. Six populations of P. vittata and four populations of S. alfredii from(More)
The Trojan population consists of two swarms of asteroids following the same orbit as Jupiter and located at the L4 and L5 stable Lagrange points of the Jupiter-Sun system (leading and following Jupiter by 60 degrees ). The asteroid 617 Patroclus is the only known binary Trojan. The orbit of this double system was hitherto unknown. Here we report that the(More)
BACKGROUND Existing evidence suggests that proinflammatory cytokines play an intermediary role in postchemotherapy cognitive impairment. This is one of the largest multicentered, cohort studies conducted in Singapore to evaluate the prevalence and proinflammatory biomarkers associated with cognitive impairment in breast cancer patients. PATIENTS AND(More)
Surface soils from Guiyu, China (an intense e-waste processing center) were analyzed for persistent organic pollutants (POPs) and variations in composition of the resident bacterial communities. Denaturing Gradient Gel Electrophoresis analysis of bacterial 16S rRNA gene showed that e-waste pollution altered the bacterial community structure by promoting(More)
The cellular characteristics and antioxidant responses including reactive oxygen species (ROS), esterase activity, superoxide dismutase, peroxidase (POD), glutathione (GSH), and malondialdehyde (MDA) content of two microalgal species, Selenastrum capricornutum and Chlorella sp., exposed to single and mixed estradiol (E2) and ethinlyestradiol (EE2) at a(More)
Giant planet atmospheric composition and satellite densities provide insights into protoplanetary disk conditions. Abundances of condensable species and noble gases in wellmixed atmospheres can distinguish among several giant planet formation scenarios, and satellite densities are fi rst order measurements of ice:rock ratios. Recent work on protosolar(More)
