This paper summarizes the performance of the world's largest PV power plant for [1984][1985][1986][1987][1988][1989]. Although the plant has high availability, energy production efficiency has declined at the rate of 8-12% per year since 1986. For the first time, performance results of mirrored and nonmirrored segments are presented. These results indicate that the non-mirrored segment is performing well with minimal efficiency degradation and low operation and maintenance costs.

Rationale
The coronavirus disease (COVID-19) pandemic exacerbated psychological distress and burnout in frontline healthcare workers. Interventions addressing psychological distress and burnout among these workers are lacking.
Objectives
To determine the feasibility and explore the impact of mobile mindfulness to treat psychological distress and burnout among nurses in frontline COVID-19 units.
Methods
We conducted a pilot randomized trial of 102 nurses working in COVID-19 units at a single hospital between May 2021 and January 2022. Participants were randomized to mobile mindfulness (intervention) or waiting list (control). The primary outcome was feasibility, assessed by comparing rates of randomization, retention, and intervention completion to predefined targets. Secondary outcomes were changes in psychological distress (Patient Health Questionnaire-9, General Anxiety Disorder-7, Perceived Stress Scale-4) and burnout symptoms (Maslach Burnout Inventory) after 1 month.
Results
We randomized 102 of 113 consented individuals (90%, target 80%), and 88 completed follow-up (86%, target 80%). Among 69 intervention participants, 19 completed ⩾1 mindfulness session per week (28%, target 60%), and 13 completed ⩾75% of mindfulness sessions (19%, target 50%). Intervention participants had greater decreases in Patient Health Questionnaire-9 scores than control subjects (difference in differences, −2.21; 95% confidence interval, −3.99, −0.42;
P
= 0.016), but the Maslach Burnout Inventory depersonalization scores decreased more in the control arm than in the intervention arm (difference in differences, 1.60; 95% confidence interval, 0.18, 3.02;
P
= 0.027). There were no other changes in emotional distress or burnout symptoms.
Conclusions
This trial of mobile mindfulness in frontline nurses met feasibility targets for randomization and retention, but participants had modest intervention use. Intervention participants had a reduction in depression symptoms, but not in burnout.
