Abstract An articulated temnospondyl skeleton from Middle Triassic deposits of Bjørnøya (Bear Island) in the western Barents Sea is described as a new plagiosaurid genus and species, Arctobatrachus urdensis. With a body length well exceeding 2 m, it represents by far the largest known member of the Plagiosauridae.

A Theory for Hydrofoils of Finite Span [PDF]
The program of this report is as follows: After a brief survey of the available theoretical and experimental information on the characteristics of hydrofoils, the theory for a hydrofoil of finite span will be formulated. The liquid medium is assumed to be incompressible and nonviscous and of infinite depth.

We introduce ENHYDROSS, a new mechanistic model that uses optimal swimming speed and minimum cost of transport to estimate maximum dispersal distances and durations for vertebrates, enabling assessment of long‐distance oceanic dispersal potential. Applied to a range of extant and extinct animals, the model's estimates generally align with observed data;

Multimodal Locomotion of Soft Robots
This review comprehensively surveys recent advances in multimodal locomotion within soft robotics. Typical locomotion modes are summarized and categorized. Furthermore, the underlying mechanisms enabling multimodal locomotion are discussed and classified into three primary categories: active control‐based, reconfiguration‐based, and environment ...

Hydrodynamic Performance of the 3D Hydrofoil at the Coupled Oscillating Heave and Pitch Motions
The purpose of this paper is to study on the power extraction of the hydrofoil by performance of the coupled oscillating heave and pitch motions. The numerical analysis is conducted by using the Reynolds Average Navier-Stokes (RANS) equations and the ...

Chemical Mechanical Polishing of Plasma‐Modified Cu/Polymer Interfaces for Advanced Hybrid Bonding
Hybrid bonding demands planarization of Cu/polymer interfaces, but soft polymers like benzocyclobutene (BCB) are difficult to polish by conventional chemical mechanical polishing (CMP). It is demonstrated that Ar plasma modification transforms BCB into a CMP‐compatible surface, enabling effective planarization and void‐free bonding.
