Anatomy and variation in the paraphyletic Mosasaurus lemonnieri assemblage from the Craie phosphatée de ciply, Belgium

open access: yesThe Anatomical Record, EarlyView.
Abstract Nineteenth century excavations of the Ciply‐Malogne Phosphatic Chalk Formation in Hainaut, Belgium, yielded over 50 partial mosasaur skeletons, the majority of which were referred to the species Mosasaurus lemonnieri Dollo, 1889. In the years since, this taxon has experienced a complicated taxonomic history, and its exceptional hypodigm has ...

Congruous Torsional Down Beating Nystagmus in the Third Position of the Semont's Maneuver in Patients Treated for Canalithiasis of Posterior Semicircular Canal Benign Paroxysmal Positional Vertigo: Its Significance and Prognostic Value

open access: yesFrontiers in Neurology, 2020
Due to its mechanical pathogenesis, benign paroxysmal positional vertigo treatment is mainly physical: when posterior semicircular canal is involved, Semont's maneuver is reported as one of the most effective liberating procedures.

Redescription of the cranial morphology of Amphisbaena braestrupi and Amphisbaena laurenti (Squamata: Amphisbaenidae) from the Pleistocene of Brazil using x‐ray computed tomography

open access: yesThe Anatomical Record, EarlyView.
Abstract Amphisbaenians (Squamata: Amphisbaenidae) are fossorial reptiles with highly specialized cranial morphology, yet their fossil record is frequently limited by fragmentary preservation. This study provides a detailed osteological redescription of the skulls of Amphisbaena braestrupi and Amphisbaena laurenti from the Pleistocene of Lagoa Santa ...

Paranasal recesses and rostral airspace volume covary with echolocation call frequency in emballonurid bats

open access: yesThe Anatomical Record, EarlyView.
Abstract The mammalian rostrum has multiple functions including serving as the upper jaw, supporting olfactory sensory structures, conditioning inspired air, and—for some mammals—transmitting sound. Several groups of bats independently evolved bony inflations on the dorsolateral surfaces of their rostra.

Gradient p‐p Orbital Hybridization in Bismuth‐Doped Crystalline Carbon Nitride for Dual‐Functional Carbon‐to‐Carbon Valorization

open access: yesEcoEnergy, EarlyView.
Schematic illustration comparing the charge transfer dynamics and catalytic reaction over the (left) pristine carbon nitride and (right) Bi‐doped carbon nitride photocatalysts. In the pristine system, random charge diffusion and rapid recombination limit catalytic efficiency. In contrast, the Bi‐doped system establishes a robust internal electric field

Spacing Effects in Guided Vertical‐Axis Wind Turbine Arrays for Highway Energy Harvesting Under Multi‐Vehicle Wake Conditions

open access: yesEnergy Science &Engineering, EarlyView.
Three‐turbine guided Savonius arrays installed along highway corridors extract up to 697 J under multi‐vehicle wake conditions when spaced 12 rotor diameters apart—68% more than compact arrangements. Guide vanes boost output by 80–120%, and interior turbines respond most strongly to spacing, governing overall array performance. ABSTRACT Highway‐induced

New geochronological constraints on Late Pleistocene glaciation in the southern Cadí Massif, SE Pyrenees

open access: yesJournal of Quaternary Science, EarlyView.
ABSTRACT The Cadí Massif (42°17′09″ N, 1°38′11″ E; 2649 m a.s.l.) in the southeastern Pyrenees preserves clear evidence of Late Pleistocene glaciation, although previous research has focused almost exclusively on its northern slope. By contrast, the southern slope has remained largely unexplored.
