Feasibility Study of implementing Wake Steering in Floating Wind Farms: Power Gain, Load Estimation and Economic Analysis

open access: yesWind Energy, Volume 29, Issue 5, May 2026.
ABSTRACT This paper presents an overview of the CONFLOWS project, a collaborative effort between DNV, Marine Power Systems (MPS) and Durham University. The project investigates the effects of wake steering from aerodynamic, structural and economic modelling perspectives, aiming to provide a comprehensive understanding of its impact on performance and ...

Hitchhiker's Guide to the Swampland: The Cosmologist's Handbook to the String‐Theoretical Swampland Programme

open access: yesFortschritte der Physik, Volume 74, Issue 4, April 2026.
Abstract String theory has strong implications for cosmology, implying the absence of a cosmological constant, ruling out single‐field slow‐roll inflation, and that black holes decay. The origins of these statements are elucidated within the string‐theoretical swampland programme.

Hamstring Mechanics During Acceleration, Deceleration and Sidestep Cutting

open access: yesScandinavian Journal of Medicine &Science in Sports, Volume 36, Issue 4, April 2026.
ABSTRACT Hamstring strain injuries (HSI) are common in field‐based sports. Musculoskeletal modeling studies have been used to investigate hamstring mechanics during steady‐state running. Accelerative and decelerative running as well as change of direction actions, which are common mechanisms of HSI, have been largely overlooked.

Pulsars With Jets May Harbor Dynamically Important Accretion Disks

open access: yes, 2003
For many astrophysical sources with jets, there is evidence for the contemporaneous presence of disks. In contrast, pulsars such as the Crab and Vela show jets but have not yet revealed direct evidence for accretion disks.
