Self‐Organized Multitarget Pursuit in Multi‐Unmanned Aerial Vehicle Systems via Hierarchical Probabilistic Graphical Models

open access: yesAdvanced Intelligent Systems, EarlyView.
Multi‐UAV systems face challenges in adversarial environments due to limited adaptability and interpretability. This study proposes a self‐organized approach using hierarchical probabilistic graphical models with density‐driven parameter estimation.

Does the abiotic environment influence the distribution of flower and fruit colors?

open access: yesAmerican Journal of Botany, EarlyView.
Abstract Premise Color in flowers and fruits carries multiple functions, from attracting animal partners (pollinators, dispersers) to mitigating environmental stress (cold, drought, UV‐B). With research historically focusing on biotic interactions as selective agents, however, it remains unclear whether abiotic stressors impact flower and fruit colors ...

The Chemistry and Biology of the Tetrodotoxin Natural Product Family

open access: yesAngewandte Chemie International Edition, EarlyView.
Tetrodotoxin is best known as the poison of the pufferfish, which is a delicacy in Japanese cuisine. Its toxicity arises from the selective blockage of NaV channels, which is depicted for the NaV1.7 pore, highlighting the DEKA motif, which permeates sodium ions.

Who was the real sabertooth predator: Thylacosmilus or Thylacoleo?

open access: yesThe Anatomical Record, EarlyView.
Abstract Sabertoothed mammalian predators, all now extinct, were almost exclusively feloid carnivorans (Eutheria, Placentalia): here a couple of extinct metatherian predators are considered in comparison with the placental sabertooths. Thylacosmilus (the “marsupial sabertooth”) and Thylacoleo (the “marsupial lion”) were both relatively large (puma ...
