Segmented Gurney Flaps for Improved Wind Turbine Wake Recovery

open access: yesWind Energy, Volume 29, Issue 3, March 2026.
ABSTRACT When wind passes through the rotor of a wind turbine, the velocity is decreased while turbulence is increased. The region of decreased wind speed behind the rotor is known as the wind turbine wake and is bounded by a complex structure of helical vortices. This structure occurs to be more stable in low ambient turbulence and low tip speed ratio

The Effect of Graphene on the Fatigue Response and Failure Mechanism of Composite Materials: A Review

open access: yesFatigue &Fracture of Engineering Materials &Structures, Volume 49, Issue 3, Page 933-962, March 2026.
ABSTRACT This review investigates the influence of graphene on the fatigue performance of polymer‐based composites, focusing on both unreinforced matrices and fiber‐reinforced composite laminates. Graphene materials, including nanoplatelets, graphene oxide, and hybrid nanostructures, offer exceptional mechanical, electrical, and barrier properties that

Mapping Flood Hazard Across Mainland China Through a Physics‐Based Global Flood Model With Embedded Reservoir Operation Scheme

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT China has complex topography, diverse flood mechanisms, and high population exposure, making it highly vulnerable to flooding, highlighting the need for robust national‐scale hazard assessments to identify flood‐prone regions. However, most existing hazard studies are limited to regional scales or rely on empirical indicator‐based methods that

Bayesian Analysis of Flood Prediction Using Mixture Models of Weighted Inverse Rayleigh and Gumbel Type‐II Distributions

open access: yesJournal of Flood Risk Management, Volume 19, Issue 1, March 2026.
ABSTRACT This article develops a two‐component mixture model combining the weighted Inverse Rayleigh (WIR) distribution and Gumbel Type‐II distribution for the estimation and prediction of flood events. The study utilizes 29 years (1990–2018) of flood data from the Federal Flood Commission (FFC) of Pakistan for the Jhelum River, using two gauging ...

Revisiting the relationship between stomatal size and speed across species – a meta‐analysis

open access: yesNew Phytologist, Volume 249, Issue 5, Page 2338-2354, March 2026.
Summary The rate of stomatal opening and closure in response to changes in light affects leaf photosynthesis and water use. However, it is unclear how strongly stomatal size (SS) and density (SD) influence stomatal conductance (gs) kinetics, and whether variation arises from methodological differences, guard cell type or degree of amphistomaty.
