Highly Enantioselective Organocatalysis with Bidentate Halogen Bond Donors

open access: yesAngewandte Chemie International Edition, Accepted Article.
As the employment of ”non‐classical” non‐covalent interactions like halogen bonding (XB) in asymmetric catalysis is still at a very early stage, there are significant challenges to overcome. In some reported cases, the relevance of halogen bonding to the catalytic action is unclear, while in others, catalyst activity is limited.

Model-based generation of representative rear-end crash scenarios across the full severity range using pre-crash data [PDF]

open access: yesarXiv
Generating representative rear-end crash scenarios is crucial for safety assessments of Advanced Driver Assistance Systems (ADAS) and Automated Driving systems (ADS). However, existing methods for scenario generation face challenges such as limited and biased in-depth crash data and difficulties in validation.

Predicting ecology and hearing sensitivities in Parapontoporia—An extinct long‐snouted dolphin

open access: yesThe Anatomical Record, EarlyView.
Abstract Analyses of the cetacean (whale and dolphin) inner ear provide glimpses into the ecology and evolution of extinct and extant groups. The paleoecology of the long‐snouted odontocete (toothed whale) group, Parapontoporia, is primarily marine with its depositional context also suggesting freshwater tolerance.
