A reappraisal of Neotropical Vanilla. With a note on taxonomic inflation and the importance of alpha taxonomy in biological studies

open access: yesLankesteriana, 2020
Despite the long-standing cultural importance and botanical interest in  Vanilla, many taxa belonging to the genus remain poorly understood. Vanilla species generally have broad geographical and ecological distributions.

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

open access: yesCAAI 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.

Advancements in breeding Fusarium resistant vanilla varieties using Next Generation Sequencing [PDF]

open access: yes, 2019
Demand for natural vanilla flavor is increasing, but the cultivated Vanilla planifolia faces critical challenges in response to biotic and abiotic stresses. In particular, Root and Stem Rot (RSR) disease caused by Fusarium oxysporum f. sp.

Hi-Val: Iterative Learning of Hierarchical Value Functions for Policy Generation [PDF]

open access: yes, 2019
Task decomposition is effective in manifold applications where the global complexity of a problem makes planning and decision-making too demanding. This is true, for example, in high-dimensional robotics domains, where (1) unpredictabilities and modeling

Trick or Treat? Pollinator attraction in Vanilla pompona (Orchidaceae)

open access: yesbioRxiv, 2021
Natural pollination of species belonging to the pantropical orchid genus Vanilla remains poorly understood. Based on sporadic records, euglossine bees have been observed visiting flowers of Neotropical Vanilla species.

Stable Imitation of Multigait and Bipedal Motions for Quadrupedal Robots Over Uneven Terrains

open access: yesAdvanced Robotics Research, EarlyView.
How are quadrupedal robots empowered to execute complex navigation tasks, including multigait and bipedal motions? Challenges in stability and real‐world adaptation persist, especially with uneven terrains and disturbances. This article presents an imitation learning framework that enhances adaptability and robustness by incorporating long short‐term ...

Variance optimal hedging for continuous time additive processes and applications

open access: yes, 2012
For a large class of vanilla contingent claims, we establish an explicit F\"ollmer-Schweizer decomposition when the underlying is an exponential of an additive process.

Computer Aided Aroma Design. II. Quantitative structure-odour relationship [PDF]

open access: yes, 2008
Computer Aided Aroma Design (CAAD) is likely to become a hot issue as the REACH EC document targets many aroma compounds to require substitution. The two crucial steps in CAMD are the generation of candidate molecules and the estimation of properties ...

Continual Learning for Multimodal Data Fusion of a Soft Gripper

open access: yesAdvanced 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 ...

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

open access: yesCyTA - 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 ...
