Solar Radiation Transfer Through a Subarctic Shrub Canopy [PDF]

, 2007
Much of the low Arctic is covered with shrubs that are partially buried by snow in winter and become exposed during melt. This study presents measurements and modeling of shortwave radiation reflection and extinction by a deciduous shrub canopy emerging ...

“Hands‐On” white matter anatomy: Using Air Anatomy gestures and tractography on simple brain sections to enhance teaching of white matter directions

Anatomical Sciences Education, EarlyView.
Abstract Teaching white matter (WM) anatomy to undergraduates is challenging. This is partly because WM fibers are oriented intricately and Klingler's dissection, the gold standard method used to demonstrate it, often requires time, advanced anatomical knowledge, and refined dissection skills.

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

Ecography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Application Research of Microstructured Flexible Sensors in Rehabilitative Wearable Sensing

iNew Medicine, EarlyView.
ABSTRACT Flexible sensors enable the continuous, real‐time monitoring of the physiological and movement signals of patients, providing data support for precise rehabilitation strategies and playing a crucial role in rehabilitation medicine. However, traditional rigid sensors are often incompatible with dynamic body contours due to their high material ...

Evaluating Youth Participatory Action Research in the Americas: Comparative Insights on Empowerment, Methodologies, and Social Change

Journal of Adolescence, EarlyView.
ABSTRACT Introduction Youth Participatory Action Research (YPAR) positions adolescents as co‐researchers to investigate and address social issues affecting their lives. While YPAR has gained global prominence, comparative research examining how it is conceptualized and practiced across regional contexts remains limited.

The Fifth Phase of the Radiation Transfer Model Intercomparison Exercise (RAMI-V): Experiment Description and Results on Actual Canopy Scenarios

Journal of Remote Sensing
This paper presents the latest results of the radiation transfer model intercomparison (RAMI) of the realistic vegetation scenarios. RAMI-V included the same one-dimensional (1D) and 3D scenes of RAMI-IV phase and 2 new realistic ones, defined through a ...

Determination of leaf area index for oil palm plantation using hemispherical photography technique [PDF]

, 2010
The present conventional (destructive) method used in determining LAI is laborious, difficult and time consuming. Thus, an image-based measurement using camera system with fish eye lens offers an alternative means for an accurate indirect measurement of ...

Leaf Area Index Derived From Hemispherical Photograph and Its Correlation with Aboveground Forest Biomass [PDF]

, 2015
Leaf area index (LAI) is one of the key physical factors in the energy exchange between terrestrial ecosystem and atmosphere. It determines the photosynthesis process to produce biomass and plays an important role in performing forest stand reflectance.
