Autonomous Excavation of Challenging Terrain using Oscillatory Primitives and Adaptive Impedance Control [PDF]

open access: yesarXiv
This paper addresses the challenge of autonomous excavation of challenging terrains, in particular those that are prone to jamming and inter-particle adhesion when tackled by a standard penetrate-drag-scoop motion pattern. Inspired by human excavation strategies, our approach incorporates oscillatory rotation elements -- including swivel, twist, and ...

Imidazo[1,5‐a]pyridines – A Versatile Platform for Structurally Distinct N‐Heterocyclic Olefins and π‐Extended Heterocycles

open access: yesAngewandte Chemie International Edition, EarlyView.
The synthesis of N‐heterocyclic olefins (NHOs) based on an imidazo[1,5‐a]pyridine scaffold is described. While C5‐alkyl or aryl substituents yield stable NHOs, alkenyl or alkynyl groups at C5 induce 6‐endo cyclization to form (dihydro)imidazo[2,1,5‐de]quinolizines with strong paratropic ring currents.

Progressive-Resolution Policy Distillation: Leveraging Coarse-Resolution Simulations for Time-Efficient Fine-Resolution Policy Learning [PDF]

open access: yesarXiv
In earthwork and construction, excavators often encounter large rocks mixed with various soil conditions, requiring skilled operators. This paper presents a framework for achieving autonomous excavation using reinforcement learning (RL) through a rock excavation simulator.

New data on the mammalian fauna from the late middle Eocene (MP 15–16) of Mazaterón (Soria, Spain): The youngest presence of the genus Prodissopsalis (Hyaenodonta, Hyaenodontidae) in Europe

open access: yesThe Anatomical Record, Volume 308, Issue 6, Page 1769-1782, June 2025.
Abstract The Hyaenodonta were the most diverse carnivorous mammals in the European Eocene and were classically divided into three subfamilies: Sinopaninae, Arfianinae, and Proviverrinae, with this latter being the most successful of the three, as it exhibited a much larger geographic and temporal range.
