The current paper studies highly dispersive optical solitons with the aid of Kudryashov’s integration algorithm. The governing model employs Kudryashov’s sextic power law of nonlinear refractive index. The inter-modal dispersion term is absent from the model. The integration scheme retrieves dark and singular solitons to the model.
Introduction: There is paucity of data on the outcomes of hospitalization for bicuspid aortic valve (BAV)-related aortopathies. Methods: We queried the NIS database (2012)(2013)(2014)(2015)(2016) for hospitalizations for elective thoracic aortic repair or acute aortic syndrome (AAS) among those with BAV versus trileaflet aortic valve (TAV).Results: Our analysis yielded 38,010 hospitalizations for elective aortic repair, of whom 34.4% had BAV, as well as 81,875 hospitalizations for thoracic AAS, of whom 1.1% had BAV. Hospitalizations for BAV were younger and had fewer comorbidities compared with their TAV counterparts. The number of hospitalizations for BAV during the observational period was unchanged. After propensity matching, elective aortic repair for BAV was associated with lower mortality (0.5% versus 1.7%, odds ratio = 0.28; 95% CI 1.5-0.50, p \ 0.001), use of mechanical circulatory support, acute stroke, and shorter length of hospital stay compared with TAV. After propensity matching, AAS among those with BAV had a greater incidence of bleeding
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
