Unsteady Aerodynamics of Bridge Decks in Transient Winds: Vortex Memory Effects and Path-Dependent Responses

open access: yesAdvances in Civil Engineering
This study unveils novel vortex memory mechanisms governing unsteady aerodynamics of streamlined bridge decks under transient winds via CFD simulation with the SST k-ω model (the acceleration magnitudes were set as ±5 m/s2 and ±10 m/s2, respectively ...

Political constitutionalism in the Nordic countries: How anti-constitutionalism captured the North and why it may not last

open access: yesGlobal Constitutionalism
The Nordic countries have often been portrayed as pioneers of human rights and international law. However, few are aware that court-protected human rights played an almost negligible role in post-Second World War Scandinavia.

Effects of Wind Clumping on Colliding Winds [PDF]

open access: yesSymposium - International Astronomical Union, 1995
Recent studies of variable Wolf-Rayet emission lines reveal a hierarchy of structures, characterized by power laws analogous to what is expected from supersonic compressible turbulence. The collision of inhomogeneous winds can be very different from the case of smooth winds.

Structural instability impairs function of the UDP‐xylose synthase 1 Ile181Asn variant associated with short‐stature genetic syndrome in humans

open access: yesFEBS Letters, EarlyView.
The Ile181Asn variant of human UDP‐xylose synthase (hUXS1), associated with a short‐stature genetic syndrome, has previously been reported as inactive. Our findings demonstrate that Ile181Asn‐hUXS1 retains catalytic activity similar to the wild‐type but exhibits reduced stability, a looser oligomeric state, and an increased tendency to precipitate ...

From Strain to Loads: Development of a Measurement Solution for Wind Turbine Transmission Input Loads during Drivetrain Testing

open access: yesSensors, 2023
As wind energy is paving the way for the energy transition from fossil to renewable energy sources, the ongoing trend of increasing the rated power of wind turbines aims to reduce the overall cost of wind energy.

A Critical Review of Wind Power Forecasting Methods—Past, Present and Future

open access: yesEnergies, 2020
The largest obstacle that suppresses the increase of wind power penetration within the power grid is uncertainties and fluctuations in wind speeds. Therefore, accurate wind power forecasting is a challenging task, which can significantly impact the ...

The (Glg)ABCs of cyanobacteria: modelling of glycogen synthesis and functional divergence of glycogen synthases in Synechocystis sp. PCC 6803

open access: yesFEBS Letters, EarlyView.
We reconstituted Synechocystis glycogen synthesis in vitro from purified enzymes and showed that two GlgA isoenzymes produce glycogen with different architectures: GlgA1 yields denser, highly branched glycogen, whereas GlgA2 synthesizes longer, less‐branched chains.

Calpain small subunit homodimerization is robust and calcium‐independent

open access: yesFEBS Letters, EarlyView.
Calpains dimerize via penta‐EF‐hand (PEF) domains. Using single‐molecule force spectroscopy, we measured the strength and kinetics of PEF–PEF homodimer binding. The interaction is robust, shows a transient conformational step before dissociation, and remains largely insensitive to Ca2+.
