Optical isolation via PT-symmetric nonlinear Fano resonances

We show that Fano resonances created by twoPT -symmetric nonlinear micro-resonators coupled to a waveguide, have line-shape and resonance position that depends on the direction of the incident light. We utilize these features in order to induce asymmetric transport, up to 47 dBs, in the optical C-window. Our theoretical proposal requires low input power and does not compromise the power or frequency characteristics of the output signal

Patient Satisfaction in the Emergency Department of Savodjbolaq Hospitals

Objective: Determination of patient satisfaction in the emergency department. Methods: Patient satisfaction in the emergency department was evaluated by a questionnaire in a descriptive analytic cross-sectional study. This questionnaire contained some questions about physician and nursing services, medical equipments, and physical environment of the emergency department. Satisfaction scores were converted to a binary score (unsatisfied and satisfied) and the association of this binary variable (satisfaction) with other demographic characteristics was measured in logistic regression model. Results: Patient satisfaction from acceptance portion and physical environment of the hospitals was moderate though from physician and nursing services was good. The correlation between satisfaction and willingness to return and also waiting time was statistically significant (OR= 1/81 CI 95% 1/10&ndash; 3/06, OR= 0/34 CI 95% 0/22&ndash; 0/74) on logistic regression analysis. The correlation between satisfaction and age, gender, refers' time and work shift did not significantly differ. Overall patient satisfaction in Hashtgerd hospital was significantly more than Nazarabad hospital (p<0/05). Conclusion: This study revealed that physician waiting times are an important factor in patient satisfaction. In present study, most of the patients were visited in less than 15 minutes and the presence of other more emergency cases were the most reason for delay in visiting times. These findings suggest that emergency department patient satisfaction improvement efforts should focus on a limited number of modifiable and easily measured factors
