Design and Verification of Multi-Mode Variable Camber Wing Trailing Edge

Engineering Proceedings
By changing the aerodynamic shape of the trailing edge of its wing, an aircraft can achieve lift and drag reduction during takeoff and landing and continuously achieve better aerodynamic efficiency while cruising, which plays an important role in the ...

New insights into convection‐permitting model simulations from a ZDR$$ {\boldsymbol{Z}}_{\mathbf{DR}} $$ diagnostic for raindrops

Quarterly Journal of the Royal Meteorological Society, EarlyView.
A polarimetric radar forward operator to simulate differential reflectivity (ZDR$$ {Z}_{\mathrm{DR}} $$) from rain was developed to evaluate simulated storms in the Met Office Unified Model (MetUM) for two case days of the Wessex Convection Experiment (WesCon) field campaign. Vertical columns of ZDR$$ {Z}_{\mathrm{DR}} $$, indicative of strong updrafts,

A Thin Blue Democratic Line? Organization, Interest, and Ethical Compatibility as Foundations of External Accountability Credibility

Regulation &Governance, EarlyView.
ABSTRACT In the context of rising authoritarian and populist political movements, scholars have increasingly identified external agency as a bulwark for liberal values. However, its capacity to protect such values may be contingent upon its acceptance within the profession—specifically, upon attitudes we conceptualize as “accountability credibility ...

Drowned carbonate‐rimmed margin controlling shelf‐edge delta progradation and sedimentation dynamics: Upper Cretaceous Woodbine Formation, Texas, USA

Sedimentology, EarlyView.
ABSTRACT Shelf‐edge deltas are commonly interpreted to record basinward facies migration across uninterrupted, gently dipping shelf margins; however, examples from mixed siliciclastic‐carbonate margins reveal more complex depositional dynamics. Periods and areas of carbonate sedimentation within mixed siliciclastic‐carbonate margins can modify shelf ...

Aerodynamic Characteristics of Airfoils Equipped With Gurney Flaps and Vortex Generators for the Entire Range of Pitch Angles

Wind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT An experimental study of NACA0021 airfoil equipped with vortex generators (VGs) and Gurney flaps (GFs) was conducted to assess the effects of these devices on the aerodynamic airfoil performance, the information that is necessary for studying the self‐starting characteristics of vertical axis wind turbines (VAWTs).

Morphology and osteo‐histology of the weigeltisaurid wing: Implications for aerial locomotion in the world's first gliding reptiles

Journal of Anatomy, Volume 248, Issue 5, Page 843-872, May 2026.
This study investigates the morphology and osteo‐histology of the wing skeleton of the world's first gliding reptiles, showing how it differs from those of extant gliding lizards, yet is also convergently similar. These findings pave the way for future biomechanical studies on the gliding locomotion of these emblematic fossil animals. Abstract The Late

Kinetics of Elastic Recoil in the Wings of the cicada, Dundubia rufivena

Natural Sciences, Volume 6, Issue 2, April 2026.
We quantify elastic recoil in cicada wings using high‐speed videography, revealing faster bending than torsional recoil. Wing stiffness increases when attached to the thorax, demonstrating a body‐wing spring system and highlighting that elastic recoil must be understood through whole‐organism mechanics rather than isolated wing properties.
