Bistatic Observations of the Ocean Surface with HF Radar, Satellite and Airborne Receivers

Embargo of 24 months from date of publishing on accepted manuscript version. Link to publisher's version:https://ieeexplore.ieee.org/document/8232298/Copyright notice:“© © 20xx IEEE policy"A new concept has been developed which can view vast regions of the Earth's surface. Ground HF transmissions are reflected by the ionosphere to illuminate the ocean over a few thousand kilometers. HF receivers detect the radio waves scattered by the sea and land surface. Using the theory of radio wave scatter from ocean surfaces, the HF data is then processed to yield the directional wave-height spectrum of the ocean. This technique has several advantages over existing remote sensing methods. A large area of the ocean can be sampled to yield the wave-height characteristics with high, km-scale resolution. The wave height spectrum can be directly compared with temporal frequency spectrum obtained with buoys at specific points in the ocean volume. Furthermore, the technique uses HF waves which penetrate the dense rain found in hurricanes

The Temporal Development of Fatty Infiltrates in the Neck Muscles Following Whiplash Injury: An Association with Pain and Posttraumatic Stress

Radiological findings associated with poor recovery following whiplash injury remain elusive. Muscle fatty infiltrates (MFI) in the cervical extensors on magnetic resonance imaging (MRI) in patients with chronic pain have been observed. Their association with specific aspects of pain and psychological factors have yet to be explored longitudinally.44 subjects with whiplash injury were enrolled at 4 weeks post-injury and classified at 6 months using scores on the Neck Disability Index as recovered, mild and moderate/severe. A measure for MFI and patient self-report of pain, loss of cervical range of movement and posttraumatic stress disorder (PTSD) were collected at 4 weeks, 3 months and 6 months post-injury. The effects of time and group and the interaction of time by group on MFI were determined. We assessed the mediating effect of posttraumatic stress and cervical range of movement on the longitudinal relationship between initial pain intensity and MFI. There was no difference in MFI across all groups at enrollment. MFI values increased in the moderate/severe group and were significantly higher in comparison to the recovered and mild groups at 3 and 6 months. No differences in MFI values were found between the mild and recovered groups. Initial severity of PTSD symptoms mediated the relationship between pain intensity and MFI at 6 months. Initial ROM loss did not.MFI in the cervical extensors occur soon following whiplash injury and suggest the possibility for the occurrence of a more severe injury with subsequent PTSD in patients with persistent symptoms

Phreatic Tendencies of Exotic Grasses and Residual Species as Indicated by Radioisotope Absorption

Rooting habits with respect to the capillary moisture zone above the watertable were studied by two methods: (1) absorption and translocation of radioactive isotopes and (2) direct observation of trench walls. Isotopes used were 131-I, 99-Mo, 51-Cr and 75-Se. In general, grasses appeared to absorb more actively in spring than in fall, and more from midlevel of the capillary zone than from the top or bottom. The highest activity was in foliage of intermediate wheatgrass which accumulated 75-Se from the watertable. While some injections resulted in no detected absorption, all grasses showed ability to pick up radioactivity at various levels in the capillary zone.This material was digitized as part of a cooperative project between the Society for Range Management and the University of Arizona Libraries.The Journal of Range Management archives are made available by the Society for Range Management and the University of Arizona Libraries.
