The research report concluded, "It appears that self-reported sleep reported of participants may be associated to the indirect effects of visual and attitudinal cue and concern about property devaluation rather than distance to the nearest WT's or noise as itself." Careful reading of the report shows that the conclusions presented are not supported by the data provided in the report.

It is found that rare extreme events are generated in a Raman fiber laser. The mechanism of the extreme events generation is a turbulent-like four-wave mixing of numerous longitudinal generation modes. OCIS codes: (190.4370) Nonlinear optics, fibers; (190.4380) Nonlinear optics, four-wave mixing Extreme type statistics in nonlinear fiber optics has attracted a great attention since the experime...

Soliton molecules are the manifestation of attractive and repulsive interaction between optical pulses mediated by a nonlinear medium. However, the formation and breakup of soliton molecules are difficult to observe due to the transient nature of the process. Using the time stretch technique, we have been able to track the real-time evolution of the bound state formation in a femtosecond fiber ...

Pulmonary arterial hypertension (PAH) is a progressive disease characterized by pulmonary vascular remodeling and right heart failure. In its advanced stage, PAH demonstrates muscularization of distal pulmonary arterioles, concentric thickening, and obstruction of vascular lumen due to the proliferation of pulmonary artery endothelial cells (PAECs) and pulmonary artery smooth muscle cells (PASM...

Introduction: Pulmonary embolism (PE) is a common, elusive, and deadly condition, with an annual incidence of over 600,000 cases, with 200,000 deaths, in the United States alone. In recent years, hyperpolarized He MRI has been applied with the aim of PE diagnosis. To date, two techniques have been proposed. The first technique measures the pulmonary partial pressure of oxygen by utilizing the f...

An electrically pumped light source on silicon is a key element needed for photonic integrated circuits on silicon. Here we report an electrically pumped AlGaInAs-silicon evanescent laser architecture where the laser cavity is defined solely by the silicon waveguide and needs no critical alignment to the III-V active material during fabrication via wafer bonding. This laser runs continuous-wave...
