“…In the absence of inclination, square patterns can develop in a horizontal layer of a binary mixture [18,32]. When subjected to a small tilt of the order of a few milliradians a transition between the square pattern and a drifting centered-rectangular one occurs [18,21]. The drifting pattern is made by parallel rows of ascending and descending columns of fluid moving into opposite directions parallel to the inclination of the fluid layer, in a superhighway convection (SHC) configuration resembling alternate rows of traffic on a highway.…”

“…A notable exception to this behavior occurs in binary liquid mixtures, where even an inclination of the sample as small as few milliradians strongly affects the convective planform [18][19][20][21][22]. This feature of binary mixtures can be qualitatively understood by taking into account that in the case of solutal convection the boundaries are impermeable.…”

We investigate pattern formation in an inclined layer of liquid water with poorly conducting boundaries. We show that above the threshold for convection the presence of an inclination larger than 14 mrad determines a transition from a square pattern to longitudinal rolls, a behavior remarkably different than the one reported in the presence of inclined conducting boundaries, where transitions between convective planforms occur at inclination angles of the order of several degrees. The longitudinal rolls are characterized by a dimensionless wave vector k ≈ 1.8, significantly smaller than k ≈ 3.117 reported for conducting boundaries at large Prandtl number. The transition can be triggered by changing dynamically the inclination of the layer of fluid, and does not occur symmetrically in the two directions. By starting in the horizontal configuration, it develops slowly through the demolition of the square structure to form longitudinal rolls, while it develops rapidly in the other direction, through the formation of a cross-roll structure perpendicular to the longitudinal rolls.

We present a precise analysis to test hypothetical models involving sterile neutrinos beyond the standard flat-ΛCDM cosmology with the CMB observations from the Planck mission and BAO measurements. This analysis shows that adding the locally measured Hubble parameter H 0 = 73.00 ± 1.75 km s −1 Mpc −1 to the data removes the need for the informative physical m thermal sterile prior in CMB constraints of m ef f ν,sterile . Under the constraints from the data containing the locally measured H 0 we obtain an upper limit m ef f ν,sterile < 0.306 eV scale mass for the massive sterile neutrino, and an upper limit Σm ν < 0.214 eV scale mass for the three degenerate massive neutrino (95 per cent confidence level). We also obtain the value σ 8 = 0.81 +0.05 −0.06 (95 per cent confidence level), which is in compatibility with the constraints from Planck 2015 CMB data at the 1σ level. We find that introducing parameter m ef f ν,sterile to the model of cosmology reduces the σ 8 value and moves it closer to the obtained value for this parameter from the KiDS-450 analysis. Our results show that the locally measured Hubble parameter can increase constraints on σ 8 values.

We investigate the abundance, small-scale clustering and galaxy-galaxy lensing signal of galaxies in the Baryon Oscillation Spectroscopic Survey (BOSS). To this end, we present new measurements of the redshift and stellar mass dependence of the lensing properties of the galaxy sample. We analyse to what extent models assuming the Planck18 cosmology fit to the number density and clustering can accurately predict the small-scale lensing signal. In qualitative agreement with previous BOSS studies at redshift z ∼ 0.5 and with results from the Sloan Digital Sky Survey, we find that the expected signal at small scales (0.1 < r p < 3 h −1 Mpc) is higher by ∼ 25% than what is measured. Here, we show that this result is persistent over the redshift range 0.1 < z < 0.7 and for galaxies of different stellar masses. If interpreted as evidence for cosmological parameters different from the Planck CMB findings, our results imply S 8 = σ 8 Ω m /0.3 = 0.744 ± 0.015, whereas S 8 = 0.832 ± 0.013 for Planck18. However, in addition to being in tension with CMB results, such a change in cosmology alone does not accurately predict the lensing amplitude at larger scales. Instead, other often neglected systematics like baryonic feedback or assembly bias are likely contributing to the small-scale lensing discrepancy. We show that either effect alone, though, is unlikely to completely resolve the tension. Ultimately, a combination of the two effects in combination with a moderate change in cosmological parameters might be needed.
