Chemical Characterization of Postindustrial Recycled Polyethylene Terephthalate Obtained From Multilayer PET/PE Sheets: A Baseline Study on Safety Aspects

open access: yesPackaging Technology and Science, Volume 39, Issue 3, Page 257-270, March 2026.
PET trays pose recycling challenges due to multilayer structures with polyethylene (PE) tie‐layers and barrier materials. In this study, a delamination process using a hot alkaline solution was applied to postindustrial multilayer PET/PE thermoforming waste to recover PET flakes and produce sheets.

A cybersecurity risk analysis framework for systems with artificial intelligence components

open access: yesInternational Transactions in Operational Research, Volume 33, Issue 2, Page 798-825, March 2026.
Abstract The introduction of the European Union Artificial Intelligence (AI) Act, the NIST AI Risk Management Framework, and related international norms and policy documents demand a better understanding and implementation of novel risk analysis issues when facing systems with AI components: dealing with new AI‐related impacts; incorporating AI‐based ...

Disparities in suicide risk trajectories among youth during the COVID‐19 pandemic

open access: yesJournal of Research on Adolescence, Volume 36, Issue 1, March 2026.
Abstract The pandemic contributed to an ongoing youth mental health crisis, though mental health burdens are disproportionately distributed within youth populations. The objective of this study was to identify latent trajectories of youth suicide risk during the COVID‐19 pandemic and examine differential risk by demographic subgroups.

Relations between ethnic‐racial identity statuses and critical consciousness among Latine adolescents

open access: yesJournal of Research on Adolescence, Volume 36, Issue 1, March 2026.
Abstract Ethnic‐racial identity (ERI) development reflects the processes through which adolescents learn about their ethnic‐racial background (i.e., exploration) and develop clarity about what it means to them (i.e., resolution). Research on ERI has been critiqued for not examining connections between ERI and broader social beliefs, such as critical ...

Large Variations in the Transpiration of Sorghum Canopies Under High Evaporative Demand Are Positively Related to Water Use Efficiency

open access: yesPlant, Cell &Environment, Volume 49, Issue 3, Page 1544-1560, March 2026.
ABSTRACT Transpiration restriction under high vapour pressure deficit (VPD), measured indoors with individual plants, increases water use efficiency (WUE). However, VPD is not the only factor driving transpiration, individual plants in a field rapidly become a canopy, and reports on the transpiration restriction versus WUE are scant.

The Geometry of Layer 2/3 Cortical Sound Processing in Slow Wave Sleep

open access: yesAdvanced Science, Volume 13, Issue 7, 3 February 2026.
Sleep is associated with a sensory disconnection whose mechanisms remain elusive. Large neuronal population recordings in the auditory cortex revealed that, in NREM sleep, the neural code for sounds is highly similar to wakefulness, but coordinated modulations of neuron responsiveness intermittently disconnect the local cortical networks from sensory ...

Detecting early memory changes in preclinical Alzheimer's disease using TabCAT favorites test: Data from the European Prevention of Alzheimer's Disease (EPAD) cohort

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION Sensitive memory paradigms may allow the detection of subtle memory changes associated with early Alzheimer's pathology in individuals without established clinical symptomatology. METHODS We explored the cross‐sectional association between performance on Tablet‐based Cognitive Assessment Tool (TabCAT) Favorites, a brief ...

AI‐enhanced Centiloid quantification of amyloid PET images

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION The Centiloid scale is the standard for amyloid (Aβ) PET quantification in research and clinical settings. However, variability between tracers and scanners remains a challenge. METHODS This study introduces DeepSUVR, a deep learning method to correct Centiloid quantification, by penalizing implausible longitudinal trajectories ...

Associations between accelerometer‐derived physical activity complexity, cognitive function, and plasma biomarkers of Alzheimer's disease

open access: yesAlzheimer's &Dementia, Volume 22, Issue 2, February 2026.
Abstract INTRODUCTION While higher physical activity (PA) levels are linked to lower Alzheimer's disease (AD) risk, traditional PA measures overlook temporal activity patterns. METHODS We developed the activity complexity measure in 164 older adults (mean age = 65.3 years) who completed wrist‐worn accelerometry and neuropsychological tests.

Uncovering Latent Structures of School Belonging, Emotional Problems, Psychological Symptoms, Meaningful School, and Ostracism: A Latent Profile Analysis

open access: yesBrain and Behavior, Volume 16, Issue 2, February 2026.
This study explored how school belonging interacts with emotional and psychological factors among adolescents. Using latent profile analysis with a sample of 749 students, four distinct profiles were identified. The first group, Distressed but Included, showed high emotional problems despite average levels of ostracism.
