Helmeted hornbill cranial kinesis: Balancing mobility and stability in a high‐impact joint
The Anatomical Record, EarlyView.Abstract Prokinesis—in which a craniofacial joint allows the rostrum to move relative to the braincase—is thought to confer diverse advantages in birds, mostly for feeding. A craniofacial joint would, however, be a weak link if cranial stability is important. Paradoxically, we have identified a craniofacial joint in helmeted hornbills (Rhinoplax vigil),

Constrained texture mapping for polygonal meshes [PDF]
Proceedings of the 28th annual conference on Computer graphics and interactive techniques, 2001 Recently, time and effort have been devoted to automatic texture mapping. It is possible to study the parameterization function and to describe the texture mapping process in terms of a functional optimization problem. Several methods of this type have been proposed to minimize deformations.

A review of multiscale numerical modeling of rock mechanics and rock engineering
Deep Underground Science and Engineering, EarlyView.Multiscale numerical methods of rock mechanics and rock engineering are reviewed, and the review results show that more attention should be paid to the development of an advanced constitutive model in addition to numerical techniques themselves. Abstract Rock is geometrically and mechanically multiscale in nature, and the traditional phenomenological ...

International Journal for Numerical Methods in Fluids, EarlyView.This article presents the principles of Finite Element‐Volume discretization and conducts an analysis of its properties and convergence orders. The discretization ensures local mass conservation, second‐order convergence for velocity, and first‐order convergence for pressure.

Price Discovery and Efficiency in Uniswap Liquidity Pools
Journal of Futures Markets, EarlyView.ABSTRACT Using almost three years of minute‐level data, we show that the efficiency of Uniswap v3 is much improved relative to v2, and some v3 pools are approaching or even exceeding Bitstamp in terms of price discovery ability. Regression results suggest that the channels of influence for these improvements are an increase in informed liquidity ...

Heavy Metal Contamination in Arenillas Ecological Reserve Soils: Correlation and Conservation Impact
Land Degradation &Development, EarlyView.ABSTRACT This study addresses the critical knowledge gap regarding heavy metal contamination in the soils of the Arenillas Ecological Reserve (AERv), located on the southwest coast of Ecuador. Despite being a fragile and highly biodiverse ecosystem, little is known about the magnitude, spatial distribution, and drivers of heavy metal contamination in ...

Discrete Chiral Ballistic Polariton Laser
Laser &Photonics Reviews, EarlyView.Planar microcavities in the strong light–matter coupling regime exhibit exciton‐polariton modes with a strong chiral response toward circularly polarized light. This feature is exploited alongside inherent spin‐orbit coupling of cavity light to generate giant discrete optical vortices in polygonal arrays of exciton‐polariton condensates.
