Arctic sea ice drift forecasts of 6 h-9 days for the summer of 2014 are generated using the Marginal Ice Zone Modeling and Assimilation System (MIZMAS); the model is driven by 6 h atmospheric forecasts from the Climate Forecast System (CFSv2). Forecast ice drift speed is compared to drifting buoys and other observational platforms. Forecast positions are compared with actual positions 24 h-8 da...

The purpose of this randomized study was to measure the influence of vitamin C (n = 15 runners) compared with placebo (n = 13 runners) supplementation on oxidative and immune changes in runners competing in an ultramarathon race. During the 7-day period before the race and on race day, subjects ingested in randomized, double-blind fashion 1,500 mg/day vitamin C or placebo. On race day, blood sa...

Abstract Many research efforts have been spent developing robust video-based algorithms for human pose estimation. Our goal was to compare estimation gait analysis. We conducted an experiment with a healthy subject performing walking sessions on treadmill at three different speeds: slow (3.6 km/h), medium (5 and high (7 km/h). An RGB 4k camera placed laterally the sagittal plane. Four were comp...

It is not clear whether or not recreational runners can recover aerobic fitness and performance within one week after marathon running. This study aimed to investigate the effects of running a marathon race on aerobic fitness and performance one week later. Eleven recreational runners (six men, five women) completed the race in 3 h 36 min 20 s ± 41 min 34 s (mean ± standard deviation). Before a...

Promising agreement over land and sea has been obtained between NEXRAD 3-GHz radar observations of precipitation rate and retrievals based on simultaneous passive observations at 50–191 GHz from the Advanced Microwave Sounding Unit (AMSU) on the NOAA-15 meteorological satellite. A neural network with three hidden nodes and one linear output node operated on 15 km resolution data at 183 1 and 18...

We have carried out VLA Zeeman observations of H i absorption lines toward the H ii region in the M17 giant molecular cloud complex. The resulting maps have 60 00 45 00 spatial resolution and 0.64 km s 1 velocity separation. The H i absorption lines toward M17 show between 5 and 8 distinct velocity components which vary spatially in a complex manner across the source. We explore possible physic...

PURPOSE To quantify the accumulative training and match load during an annual season in English Premier League soccer players classified as starters (n = 8, started ≥60% of games), fringe players (n = 7, started 30-60% of games) and nonstarters (n = 4, started <30% of games). Methods Players were monitored during all training sessions and games completed in the 2013-14 season with load quantifi...
