In Vitro Culture Strategies for the Conservation and Sustainable Use of Vanilla planifolia Andrews: A Comprehensive Review

Journal of Zoological and Botanical Gardens
Vanilla planifolia is an endangered orchid of significant commercial relevance, primarily valued for the natural vanillin derived from its cured fruits. However, its global production faces critical threats due to its limited genetic variability and high

Rediscovery and revalidation of the Brazilian endemic Vanilla schwackeana Hoehne (Orchidaceae): its distribution and phylogenetic position

Plant Ecology and Evolution
Background and aims – With 40 species, Brazil is the centre of diversity for Vanilla. Frederico Carlos Hoehne described eight Vanilla species for the Brazilian flora, including Vanilla schwackeana, an obscure taxon currently assumed to be a synonym of V.

Land‐use history determines stand structure and tree diversity in vanilla agroforests of northeastern Madagascar

Applied Vegetation Science, 2021
Question: In human- modified tropical landscapes, agroforestry is considered a promising land use to reconcile biodiversity conservation with production goals. The role of agroforests regarding conservation may be strongly influenced by land- use history;

Wavelength‐Multiplexed 2D Beam Steering via a Passive Diffractive Network

Advanced Optical Materials, EarlyView.
Illustration of a wavelength‐multiplexed diffractive beam steering system, which is composed of K cascaded diffractive layers, each containing phase‐modulating elements that are jointly optimized using deep learning–based optimization. When illuminated with a set of wavelengths {λ1,λ2,…,λNw}$\{ {{{\lambda }_1},{{\lambda }_2},\ldots ,{{\lambda }_{{{N}_w}

Learning Highly Dynamic Skills Transition for Quadruped Jumping Through Constrained Space

Advanced Robotics Research, EarlyView.
A quadruped robot masters dynamic jumps through constrained spaces with animal‐inspired moves and intelligent vision control. This hierarchical learning approach combines imitation of biological agility with real‐time trajectory planning. Although legged animals are capable of performing explosive motions while traversing confined spaces, replicating ...

A safe reinforcement learning approach for autonomous navigation of mobile robots in dynamic environments

CAAI Transactions on Intelligence Technology, EarlyView., 2023
Abstract When deploying mobile robots in real‐world scenarios, such as airports, train stations, hospitals, and schools, collisions with pedestrians are intolerable and catastrophic. Motion safety becomes one of the most fundamental requirements for mobile robots.

Volatile compounds and fatty acids in oleoresins from Vanilla Planifolia Andrews obtained by extraction with supercritical carbon dioxide

CyTA - Journal of Food, 2019
Vanilla is currently sold as an ethyl alcoholic extract, typically at a concentration of 35% (v/v). Alcoholic extracts have some disadvantages, such as high concentrations of organic residues, long extraction times and the requirement of large volumes ...

Non-Vanillin Vanilla Volatiles in Vanilla Extract

Journal of AOAC INTERNATIONAL, 1971
Abstract The flavors of vanilla extract may be made stronger by the artful addition of volatile chemicals. This method detects these additions by gas chromatography at levels down to 10 ppm. The volatiles are extracted with isopentane, which is then concentrated to 0.2-0.5 ml, at which point vanillin is precepitated before chromatography.

Continual Learning for Multimodal Data Fusion of a Soft Gripper

Advanced Robotics Research, EarlyView.
Models trained on a single data modality often struggle to generalize when exposed to a different modality. This work introduces a continual learning algorithm capable of incrementally learning different data modalities by leveraging both class‐incremental and domain‐incremental learning scenarios in an artificial environment where labeled data is ...
