Direct Estimation of Forest Leaf Area Index based on Spectrally Corrected Airborne LiDAR Pulse Penetration Ratio

Remote Sensing, 2020
The leaf area index (LAI) is a crucial structural parameter of forest canopies. Light Detection and Ranging (LiDAR) provides an alternative to passive optical sensors in the estimation of LAI from remotely sensed data. However, LiDAR-based LAI estimation

Intercomparison and sensitivity analysis of Leaf Area Index retrievals from LAI-2000, AccuPAR, and digital hemispherical photography over croplands

Agricultural and Forest Meteorology, 2008
Validation of Leaf Area Index (LAI) derived from moderate resolution remote sensing observations generally involves optical technique to measure ground LAI. As the current validation datasets are derived using multiple optical retrieval techniques, assessment of the consistency between these techniques is required.

Sleep in Young Children With Autism, ADHD and Combined Presentations

Autism Research, EarlyView.
ABSTRACT Autism and attention deficit hyperactivity disorder (ADHD) are often accompanied by sleep problems. Longitudinal studies hint towards a greater proportion of persisting sleep problems across early development in neurodivergent compared to neurotypical individuals. Within the context of a prospective infant sibling study of autism and ADHD (n =

Adaptive Functioning, Sensory Processing, and Behavioral Problems in Autistic Children: The Moderating Role of Gender

Autism Research, EarlyView.
ABSTRACT Children with autism spectrum disorder (ASD) frequently experience elevated emotional and behavioral difficulties, yet factors associated with variability remain incompletely understood. Adaptive functioning and sensory processing differences have been linked to behavioral problems, but little is known about whether associations differ between

Life as an ethnic minority (EM) university student: Comparing mental health challenges among local and international EM students in Hong Kong

British Educational Research Journal, EarlyView.
Abstract University students globally face growing mental health challenges, with ethnic minority (EM) students—both local and international—being particularly vulnerable. Yet, limited research compares their experiences or identifies shared and distinct stressors, especially in non‐Western contexts.
