Cosmic Microwave Background as a Thermal Gas of SU(2) Photons: Implications for the High-z Cosmological Model and the Value of H0 by Steffen Hahn, Ralf Hofmann

“…To make contact with successful low-z  ΛCDM cosmology we propose an interpolation based on percolated/depercolated vortices of a Planck-scale axion condensate. For a first consistency test of such an all-z model we compute the angular scale of the sound horizon at photon decoupling.…”

Second harmonic Bessel-Gauss beam shaping with elliptic axicon aberrations by Tianhong Wang, Finn Buldt, Pascal Bassène, Saad Bin Ali Reza, Edwin Fohtung, Thomas A. Searles, Chiu Tai Law, Moussa N'Gom

“…Our numerical simulations produce beam dynamics consistent with that of experiments and further implicate the remarkable interweaving of bright spots with dark vortices. This is especially noticeable when the beams dynamically oscillate along the optical axis, resulting in the genesis of spatially polarized beams with a knotted framework. …”

Improved equivalent optical turbulence method for anisotropic compressible and atmospheric turbulence under different beam transmission distances by Wenjie Wu, Jinyu Xie, Lu Bai

“…Abstract The impact of different turbulence on beams can be seen as optical distortions caused by refractive index fluctuations around vortices in turbulence. Therefore, from the perspective of transmission effects, the transmission outcomes of beam in different turbulences can be mutually equivalent. …”

Numerical Investigation on Flapping Aerodynamic Performance of Dragonfly Wings in Crosswind by Chao Wang, Rui Zhang, Chaoying Zhou, Zhenzhong Sun

“…These may accelerate the lateral skewing of the dragonfly, and the increased rolling and pitching moments will further aggravate the instability of the dragonfly model. The vorticities and reattached flow on the wings move laterally to one side due to the crosswind, and the pressure on wing surfaces is no longer symmetrical and hence, the balance between the aerodynamic forces of the wings on two sides is broken. …”

Climatological Statistics of Extreme Geomagnetic Fluctuations With Periods From 1 s to 60 min by N. C. Rogers, J. A. Wild, E. F. Eastoe, J. Hübert

“…Rates of exceedance are explained by reference to the magneto‐ionospheric processes dominant in different latitude and MLT sectors, including ULF waves, interplanetary shocks, auroral substorm currents, and traveling convection vortices. By fitting generalized Pareto tail distributions above P99.97, we predict return levels (RLs) for Rn and Sn over return periods of between 5 and 500 years. …”
