Signals of Opportunity Reflectometry at Multiple Frequencies and Polarizations: Simulation Studies and Instrument Validation

James L. Garrison, Benjamin R. Nold, Seho Kim, Eric P. Smith et autres

Signals of Opportunity reflectometry (SoOp-R) employs existing non-cooperative transmitters as sources of illumination in bistatic radar. In the typical application, these sources are communication satellites. Cross-correlation between a direct line of sight signal and a reflected path signal (or autocorrelation of the …

Longitudinal Assessment of Sleep Apnea in the Year After Stroke in a Population-Based Study

Lynda D. Lisabeth, Guanghao Zhang, Ronald D. Chervin, Xu Shi et autres

BACKGROUND: The aim of this study was to characterize change in sleep-disordered breathing severity in the year following stroke, overall, and by ethnicity, within the population-based Brain Attack Surveillance in Corpus Christi Project. METHODS: First-ever ischemic strokes (n=414) were ascertained by active …

Sleep-Disordered Breathing Is Associated With Recurrent Ischemic Stroke

Devin L. Brown, Fatema Shafie Khorassani, Sehee Kim, Ronald D. Chervin et autres

Background and Purpose- Limited data are available about the relationship between sleep-disordered breathing (SDB) and recurrent stroke and mortality, especially from population-based studies, large samples, or ethnically diverse populations. Methods- In the BASIC project (Brain Attack Surveillance in Corpus Christ), we identified …

Wake-up stroke is not associated with sleep-disordered breathing in women

Devin L. Brown, Chengwei Li, Ronald D. Chervin, Erin C. Case et autres

BACKGROUND: We sought to investigate the frequency of wake-up stroke (WUS) and its association with sleep-disordered breathing (SDB) in women. METHODS: Within a population-based study, women with acute ischemic stroke were asked about their stroke symptom onset time. SDB screening was performed …

Abstract WP357: Prevalence of Pre- and Post-intracerebral Hemorrhage Sleep-disordered Breathing

Richard V. Scheer, Lynda D. Lisabeth, Chengwei Li, Erin C. Case et autres

Background: Sleep-disordered breathing (SDB) is an independent risk factor for stroke. The reported prevalence of SDB after stroke ranges from 60 to >70%, while the pre-stroke prevalence of SDB is less well described. Moreover, much of these data are derived from ischemic …
