Plastic luminescence in mechanoluminescent composites

InfoMat, EarlyView.
Through compression tests and numerical simulations, this study demonstrates that the luminescence of a mechanoluminescent (ML) composite is strongly associated with plastic strain, thereby providing new insight into deformation‐induced luminescence during the plastic stage.

A multicenter, controlled, randomized trial of home‐applied dual‐light photodynamic therapy in stage I to III periodontitis (LumoNorth2022 study)

Journal of Periodontology, EarlyView.
Abstract Background Periodontitis is a widespread, chronic infection‐triggered inflammatory condition in which professional supportive periodontal care (SPC) and daily oral hygiene form the backbone to reduce the disease activity. Light‐based treatments have shown promising antibacterial effects, but their potential for routine home use has not been ...

Manufacturing Nostalgia in the Digital Age: A Foreverism Perspective

Psychology &Marketing, EarlyView.
ABSTRACT Many scholars argue that we are experiencing the era of “retro”—nostalgia‐driven marketing and consumption phenomena reinforced by digital technologies. However, existing research lacks a critical analysis of nostalgia in contemporary markets and of how digital content, tools, and environments transform retro consumption experiences and alter ...

SPG4 Hereditary Spastic Paraplegia: From Etiology to Therapy

Movement Disorders, EarlyView.
Abstract Hereditary spastic paraplegias (HSPs) comprise a heterogeneous group of heritable neurodegenerative disorders resulting from mutations in a wide variety of genes. HSP locomotor symptoms include lower limb weakness and spasticity that arise from progressive degeneration of corticospinal axons projecting from the motor cortex to the distal ...

On Order Restricted Inference in Multi‐Step Stage Life Testing for a General Family of Distributions

Naval Research Logistics (NRL), EarlyView.
ABSTRACT Recently, k$$ k $$‐step stage life testing (SLT) has been proposed by Laumen and Cramer (2021) as a natural extension of progressive censoring with fixed censoring times (PC‐FCT) as well as of simple step‐stress accelerated life testing (SSALT).
