TL;DR: This review discusses several critical controversies in this field and lays special emphasis on the cellular and biochemical reactions related to the formation mechanisms of lipofuscin, ceroid, advanced glycation end-products (AGEs), and age pigment like fluorophores (APFs).

TL;DR: High-resilience positive-intrinsic-negative perovskite solar cells are demonstrated by incorporating a piperidinium-based ionic compound into the formamid inium-cesium lead-trihalide perovSKite absorber, and detailed degradation routes that contribute to the failure of aged cells are revealed.
Abstract: Longevity has been a long-standing concern for hybrid perovskite photovoltaics. We demonstrate high-resilience positive-intrinsic-negative perovskite solar cells by incorporating a piperidinium-based ionic compound into the formamidinium-cesium lead-trihalide perovskite absorber. With the bandgap tuned to be well suited for perovskite-on-silicon tandem cells, this piperidinium additive enhances the open-circuit voltage and cell efficiency. This additive also retards compositional segregation into impurity phases and pinhole formation in the perovskite absorber layer during aggressive aging. Under full-spectrum simulated sunlight in ambient atmosphere, our unencapsulated and encapsulated cells retain 80 and 95% of their peak and post-burn-in efficiencies for 1010 and 1200 hours at 60° and 85°C, respectively. Our analysis reveals detailed degradation routes that contribute to the failure of aged cells.

TL;DR: The reliability studies showed that handgrip and indexgrip strength measured with the Jamar dynamometer is a reliable method and can be recommended for use in clinical practice, and sex is a more important determinant of hand strength than age, height and body weight.
Abstract: The intra- and inter-tester reliability for measurement of handgrip strength and indexgrip strength using the Jamar dynamometer was investigated in 32 healthy volunteers, and the intra-tester relia ...

TL;DR: Findings suggest that comprehensive risk assessments and the aim of reaching a low-risk profile are valid in PAH.
Abstract: Aims: Guidelines recommend a goal-oriented treatment approach in pulmonary arterial hypertension (PAH). The aim is to reach a low-risk profile, as determined by a risk assessment instrument. This s ...

TL;DR: A quantitative meta-analysis of 41 studies examining the effects of cognitive behavior therapy for generalized anxiety disorder in adults found some indications that CBT was also effective at follow-up and thatCBT was more effective than applied relaxation in the longer term.
