LaiPen LP 100 - a new device for estimating forest ecosystem leaf area index compared to the etalon: A methodologic case study

Journal of Forest Science, 2018
Fast and precise leaf area index (LAI) estimation of a forest stand is frequently needed for a wide range of ecological studies. In the presented study, we compared side-by-side two instruments for performing LAI estimation (i.e.

Comparative Evaluation of Algorithms for Leaf Area Index Estimation from Digital Hemispherical Photography through Virtual Forests

Remote Sensing, 2021
The in situ leaf area index (LAI) measurement plays a vital role in calibrating and validating satellite LAI products. Digital hemispherical photography (DHP) is a widely used in situ forest LAI measurement method.

Clade‐wide morphological and functional variation of the sauropsid columella

The Anatomical Record, EarlyView.
Abstract The columella (=stapes) is the middle ear bone of reptiles that transmits vibrations from the environment to the inner ear. It has been shown to exhibit extensive interspecific morphological disparity in several clades; however, its morphological variation and associated functional consequences remain poorly described.

Estimation of leaf area index from PROBA/CHRIS hyperspectral multi-angular data

, 2008
Leaf Area Index (LAI) is a key structural and functional biophysical variable of the vegetated surfaces which is important in quantifying evapotranspiration rates and the energy exchange of terrestrial vegetation.

Retrieving the Leaf Area Index of Dense and Highly Clumped Moso Bamboo Canopies from Sentinel-2 MSI Data

Remote Sensing
The effects of leaf clumping on leaf area index (LAI, m2·m−2) retrieval have been proved by several studies. For dense and highly clumped Moso bamboo canopies, LAI is usually retrieved using the SAIL-series models that do not account for leaf clumping ...

Comparison of Vegetation Indices for Leaf Area Index Estimation in Vertical Shoot Positioned Vine Canopies with and without Grenbiule Hail-Protection Netting

Remote Sensing, 2019
Leaf area per unit surface (LAI—leaf area index) is a valuable parameter to assess vine vigour in several applications, including direct mapping of vegetative−reproductive balance (VRB).

From anthelmintic to neuro‐oncology: A systematic review of mebendazole repurposing for brain tumour therapy

British Journal of Clinical Pharmacology, EarlyView.
Abstract Aim Mebendazole (MBZ), a benzimidazole anthelmintic with established clinical use, has emerged as a repurposing candidate for primary brain tumours due to its multimodal anticancer actions and central nervous system penetrance. This systematic review synthesizes preclinical and clinical evidence evaluating MBZ's efficacy, mechanisms of action ...

Measurement and modelling litter biomass and leaf area index using allometry in a Beech-Hornbeam stand in the mid-elevation of the Hyrcanian region, Iran [PDF]

تحقیقات جنگل و صنوبر ایران, 2014
Litter biomass and leaf area index (LAI) are two important attributes which play crucial roles on the biological processes which impact forest productivity, including photosynthesis, water and nutrient cycles.

Estimating Leaf Area Index with Dynamic Leaf Optical Properties

Remote Sensing, 2021
Leaf area index (LAI) plays an important role in models of climate, hydrology, and ecosystem productivity. The physical model-based inversion method is a practical approach for large-scale LAI inversion.

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.
