Investigating the exciton dynamics in InGaN/GaN core-shell nanorods using time-resolved cathodoluminescence.

This study examines the exciton dynamics in InGaN/GaN core-shell nanorods using time-resolved cathodoluminescence (TRCL), which provides nanometer-scale lateral spatial and tens of picoseconds temporal resolutions. The focus is on thick (>20 nm) InGaN layers on the non-polar, semi-polar and polar InGaN facets, which are accessible for study due to the unique nanorod geometry. Spectrally integrated TRCL decay transients reveal distinct recombination behaviours across these facets, indicating varied exciton lifetimes.

Lung cancer patients' illness perceptions: Prognostic for psychological and physical health trajectories.

Objective: Advanced nonsmall cell lung cancer (NSCLC) is associated with the highest burden of mental and physical symptoms. Across illnesses, patients' subjective illness beliefs (i.e.

Functional resilience and overall survival in adults treated for advanced non-small-cell lung cancer.

Purpose: As more treatments emerge for advanced, stage IV non-small-cell lung cancer (NSCLC), oncologists have difficulty predicting functional resiliency versus functional decline throughout cancer treatment. Our study evaluates functional resilience among patients with advanced NSCLC.

Methods: Functional status was evaluated through 12 months of follow-up based on disability score using the modified EQ-5D-5L (mEQ-5D-5L) survey.

Restrictions of cigarette and e-cigarette flavor and filter ventilation on demand and substitution in the Experimental Tobacco Marketplace.

Significance: Tobacco product design features, including flavors and cigarette filter ventilation, are subject to regulation. This study examined the effects of cigarette and e-cigarette flavors on demand and substitution by preferred cigarette flavor and ventilation in the Experimental Tobacco Marketplace (ETM).

Methods: In a mixed between-group (usual cigarette flavor and ventilation)/within-subject design (policy conditions), individuals who use tobacco (n=176 cigarette (60.

Estimating the Causal Effect of Filter Ventilation Levels in Cigarettes on Past 30-Day Smoking.

Introduction: Cigarettes with higher levels of filter ventilation (FV) are misperceived as less harmful and may be more appealing to consumers. Setting limits on FV has been considered as a policy, but a better understanding of any potential unintended consequences is needed.

Methods: FV (0.
