Subsistence Through Disappearance: Theology of the Unseen in the Films of Michelangelo Antonioni
Future Humanities, Volume 4, Issue 1, May 2026.ABSTRACT The present study contends that the theology of Michelangelo Antonioni's 1960s cinema is structured by a reductio ad absurdum logic, whereby the presence of certain qualities is proven by the portrayal of their absence. It is argued that Antonioni's intention to show what is by specifying what is not may have been rooted in a modernist ...

Impacts of Blade Camber on Cross‐Flow Turbine Performance and Loading
Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Cross‐flow turbines show promise for renewable energy generation from wind and tidal sources. The rotating reference frame of cross‐flow turbine blades results in virtual camber and incidence due to streamline curvature, altering the lift, drag, and pitching moment of the blades. Adding geometric camber is therefore likely to alter performance

Wind Energy, Volume 29, Issue 5, May 2026.ABSTRACT Yaw engineering models are commonly used as add‐ons to the industrial blade element momentum (BEM) framework to improve load and power predictions by accounting for the skewed wake effect. However, existing yaw engineering models show noticeable limitations in accurately predicting the induced velocity distribution across the blade span.

Entrainment of Muddy Sediment From Immobile Gravel River Beds
Water Resources Research, Volume 62, Issue 5, May 2026.Abstract This study examines the transport of fine muddy sediment through a gravel‐bed reach. In such cases, mud is often conceptualized as a size fraction that interacts little with the bed (i.e., as washload). However, previous studies have shown that mud can deposit within gravel beds.

Energy Science &Engineering, Volume 14, Issue 4, Page 1935-1951, April 2026.This paper aims to provide a robust design approach for HAWTs operating in shear flow. This study fills a critical research gap by integrating BEM and vortex theories for blade design in non‐homogeneous inflow conditions. The authors of the paper made an effort to develop and test an experimentally unsophisticated model of a turbine working in shear ...

International Journal for Numerical Methods in Fluids, Volume 98, Issue 4, Page 448-468, April 2026.The proposed work implements a direct flux reconstruction method for spatial discretization and a stiffness‐resilient exponential time integration method for temporal discretization on the cube‐sphere grid. A space‐time tensor formalism is employed to provide a general representation in any curvilinear coordinate system. This combination enables highly

Dynamic Modeling and Simulation of Morphing Wing Aircraft Considering Rigid‐Elastic Coupling Effects
International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 65-85, March 2026.ABSTRACT During the morphing process, the dynamic modeling of the morphing wing aircraft presents the characteristics of rigid‐elastic coupling effects, moving boundaries, and low computational efficiency. Meanwhile, parameters such as aerodynamic forces/moments, center of pressure, center of mass, and moment of inertia would also change significantly,
