2021 IEEE International Geoscience and Remote Sensing Symposium IGARSS, 2021 Vegetation Optical Depth (VOD) is highly sensitive to Above-ground Biomass (AGB), particularly at L-band, as this band is more sensitive to the canopy layer and has greater ca pacity to penetrate the vegetation. However, higher frequen cies, such as C- and X-bands are more related to smaller veg etation structures.

Boron deficiency responses in maize (Zea mays L.) roots
Journal of Plant Nutrition and Soil Science, EarlyView., 2023 Abstract Background Boron (B) is an essential micronutrient for plants. Dicot plants respond to insufficient B supply by altering root architecture and root hair growth. How root systems of rather low‐B demanding monocot species such as maize (Zea mays L.) respond to B deficiency in terra has not been experimentally resolved, yet.

Advanced Intelligent Systems, EarlyView.Artificial intelligence (AI) is reshaping autonomous mobile robot navigation beyond classical pipelines. This review analyzes how AI techniques are integrated into core navigation tasks, including path planning and control, localization and mapping, perception, and context‐aware decision‐making. Learning‐based, probabilistic, and soft‐computing methods

Asia-Pacific Journal of Chemical Engineering, EarlyView.ABSTRACT Greenhouse gas (GHG) emissions have emerged as one of the most critical drivers of climate change; this is primarily due to high concentrations and long atmospheric life of carbon dioxide (CO2). For a significant amount of time, various biological processes such as microalgal cultivation, cyanobacterial systems, photosynthetic microorganisms ...

, 2020 The Soil Moisture Active Passive (SMAP) satellite has provided soil moisture estimates in the top 5 cm of the soil surface by measuring the brightness temperature at L-band ($f$=1.41 GHz, $\lambda$=21 cm) emitted from the earth at a spatial resolution of 33 km. The SMAP products have been assessed by comparing them with ground-based in \emph{situ} soil

L-band vegetation optical depth and effective scattering albedo estimation from SMAP
Remote Sensing of Environment, 2017 Over land the vegetation canopy affects the microwave brightness temperature by emission, scattering and attenuation of surface soil emission. Attenuation, as represented by vegetation optical depth (VOD), is a potentially useful ecological indicator. The NASA Soil Moisture Active Passive (SMAP) mission carries significant potential for VOD estimates ...

3D anatomical atlas of the heads of male and female adult Chamaeleo calyptratus
The Anatomical Record, EarlyView.The veiled chameleon is a model organism in reptile development research. Utilizing contrast‐enhanced microCT and deep learning segmentation models, we have generated the first digital atlases of the skull, nervous system, cranial muscles and hyolingual muscles.
