Physiological parameters to support attention deficit hyperactivity disorder diagnosis in children: a multiparametric approach.

Introduction: Attention deficit hyperactivity disorder (ADHD) is a high-prevalent neurodevelopmental disorder characterized by inattention, impulsivity, and hyperactivity, frequently co-occurring with other psychiatric and medical conditions. Current diagnosis is time-consuming and often delays effective treatment; to date, no valid biomarker has been identified to facilitate this process. Research has linked the core symptoms of ADHD to autonomic dysfunction resulting from impaired arousal modulation, which contributes to physiological abnormalities that may serve as useful biomarkers for the disorder.

Spectral Control by Silver Nanoparticle-Based Metasurfaces for Mitigation of UV Degradation in Perovskite Solar Cells.

Perovskite solar cells are considered to be one of the most promising solar cell designs in terms of photovoltaic efficiency. However, their practical deployment is strongly affected by their short lifetimes, mostly caused by environmental conditions and UV degradation. In this contribution, we present a metasurface made of silver nanoparticles used as a UV filter on a perovskite solar cell.

Modulating Polymerase Activity Through Light-Oxygen-Voltage Domain Insertion.

Biochemical reaction networks adapt to environmental conditions by sensing chemical or physical stimuli and using tightly controlled mechanisms. While most signals come from molecules, many cells can also sense and respond to light. Among the biomolecular structures that enable light sensing, we selected a light-oxygen-voltage (LOV) domain in a previous study that tested the engineering of novel regulatory mechanisms into a nucleic acid polymerase.

Caregiver-reported emotional-behavioral symptoms in Spanish youth during the COVID-19 pandemic: a longitudinal study.

Background: COVID-19 pandemic stressors affected youth's mental health. This longitudinal study aims to explore these effects while considering predictive factors such as age and sex.

Methods: An initial sample of 1502 caregivers answered a longitudinal survey evaluating their youths' (4-17 years of age) emotional/behavioral symptoms using the Pediatric Symptom Checklist (PSC) screening tool.

Optical Sensing Using Hybrid Multilayer Grating Metasurfaces with Customized Spectral Response.

Customized metasurfaces allow for controlling optical responses in photonic and optoelectronic devices over a broad band. For sensing applications, the spectral response of an optical device can be narrowed to a few nanometers, which enhances its capabilities to detect environmental changes that shift the spectral transmission or reflection. These nanophotonic elements are key for the new generation of plasmonic optical sensors with custom responses and custom modes of operation.
