Exceptional points in a passive strip waveguide
No full textExceptional points (EPs) in non-Hermitian systems have attracted significant interest due to their unique behaviors, including novel wave propagation and radiation. While EPs have been explored in various photonic systems, their integration into standard photonic platforms can expand their applicability to broader technological domains. In this work, we propose and experimentally demonstrate EPs in an integrated photonic strip waveguide configuration, exhibiting unique deep wave penetration and uniform-intensity radiation profiles. By introducing the second-order grating on one side of the waveguide, forward and backward propagating modes are coupled both directly through second-order coupling and indirectly through first-order coupling via a radiative intermediate mode. To describe the EP behavior in a strip configuration, we introduce modified coupled-mode equations that account for both transverse and longitudinal components. These coupled-mode formulas reveal the formation of EPs in bandgap closure, achieved by numerically optimizing the grating's duty cycle to manipulate the first- and second-order couplings simultaneously. Experimental observations, consistent with simulations, confirm the EP behavior, with symmetric transmission spectra and constant radiation profiles at the EP wavelength, in contrast to conventional exponential decay observed at detuned wavelengths. These results demonstrate the realization of EPs in a widely applicable strip waveguide configuration, paving the way for advanced EP applications in nonlinear and ultrafast photonics, as well as advanced sensing technologies

Bridging the gap: A systematic review of patient safety culture in rural hospitals
No full textPatient safety culture (PSC) is essential for quality care and reducing safety events in hospitals.
While urban hospital PSC has been widely studied, rural hospitals, which face unique challenges
like limited resources and staffing remain underrepresented. This systematic review explored PSC
in rural U.S. hospitals, focusing on AHRQ's Hospital Survey on Patient Safety Culture (HSOPSC)
composites: Management Support for Patient Safety, Staffing and Work Pace, Response to Error,
and Handoff and Information Exchange. Using a modified PRISMA approach, six key themes
emerged from the literature. Additionally, a factor analysis of HSOPSC responses from a rural
Nebraska hospital identified three factors reflecting rural-specific considerations. While these factors
align with the literature's themes, they highlight the need for tailored PSC strategies. This study
underscores the importance of context-specific interventions and calls for future research to develop
adaptable PSC models suited to the rural healthcare environment in the United States
