Subregion independence in gravity

open access: yesJournal of High Energy Physics
In gravity, spacelike separated regions can be dependent on each other due to the constraint equations. In this paper, we give a natural definition of subsystem independence and gravitational dressing of perturbations in classical gravity.

Development and validation of an Age-related Language Decline Scale (ALDS) for older adults

open access: yesActa Psychologica
Objectives: Language decline in older adults poses a great threat to their independence. A self-report scale designed to measure age-related language decline could be very efficient, but it is still lacking.

Hierarchical composite endpoints in clinical trials for multimorbid older adults

open access: yesEClinicalMedicine
Summary: Hierarchical composite endpoints (HCEs) has the potential to make clinical trials for multimorbid older adults more relevant. Unlike conventional time-to-first-event analyses—which can give more weight to outcomes of lesser relevance—HCEs rank ...
