When two phases are studied it is often called interfacial tension.

Correction calculations for rings are made using models from Huh and Mason (Harkins and Jordan, Zuidema & Waters and others also available).Sigma 700/701 force tensiometers come with the OneAttension software for unparalleled Recent studies have presented evidence for tension between the constraints on Omega_m and sigma_8 from the cosmic microwave background (CMB) and measurements of large-scale structure (LSS). This tension can potentially be resolved by appealing to extensions of the standard model of cosmology and/or untreated systematic errors in the modelling adshelp[at]cfa.harvard.edu The ADS is operated by the Smithsonian Astrophysical Observatory under NASA Cooperative Agreement NNX16AC86A While longitudinal stabilisation was satisfactory, the processed Si tends to have a transverse curvature which is difficult to control sufficiently well by the spring tension. Alternative solutions consisting of semi-supported options (e.g. Si/Be) are presently under study, which should yield better overall stability. In order to take into account the well-known tension on the value of the fluctuation amplitude parameter, $\sigma_8$, we also consider Cluster Number counts (CN) and Weak Lensing (WL) data.

Yes, for a wide range of cosmological models ($\\Lambda$CDM, non-interacting $w_z$CDM or models with possible interactions between dark energy and dark matter, in The cosmological term, Λ, was introduced 104 years ago by Einstein in his gravitational field equations. Whether Λ is a rigid quantity or a dynamical variable in cosmology has been a matter of debate for many years, especially after the introduction of the general notion of dark energy (DE).

We also examine the possibility of addressing the H-0 and sigma(8) tensions, finding that only the former can be partially alleviated.

We also consider alternative explanations including a lower redshift for reionization that would be in conflict with polarisation measurements made by WMAP and $ad$-$hoc$ modifications to primordial power spectrum. Perhaps the most convincing one is related to sigma8, a measure of the clumpiness of the LSS, defined by the rms variance of the matter density field on a 8 Mpc/ h scale: sigma8 governs the amplitude of the matter power spectrum P (k), and it is customary to compare it across different probes (e.g.

Sigma / ˈ s ɪ ɡ m ə / (uppercase Σ, lowercase σ, lowercase in word-final position ς; Greek: σίγμα) is the eighteenth letter of the Greek alphabet.In the system of Greek numerals, it has a value of 200.

A partial cause for this reduced tension is the fact that more recent data tend to probe higher redshifts (with higher errorbars) where there is degeneracy among different models due to matter domination. We find that the well known tension in $\sigma_8$ between Planck CMB and large scale structure (LSS) observations is (1) exacerbated in the HS model and (2) somewhat alleviated in the DDE model. We The new discrepancy—called the sigma-eight tension—involves measuring the density of matter in the universe and the degree to which it is clumped up, as opposed to being uniformly distributed. The While longitudinal stabilisation was satisfactory, the processed Si tends to have a transverse curvature which is difficult to control sufficiently well by the spring tension. Alternative solutions consisting of semi-supported options (e.g. Si/Be) are presently under study, which should yield better overall stability.

Stimulated by the sigma_8 tension that the sigma_8 value derived from LSS measurements is ~ 3\sigma lower than that derived from CMB assuming LCDM, there have been many discussions about the signatures of new physics, e.g. interacting dark sector. In several previous works, the dark matter-dark radiation (DM-DR)interaction was claimed to be favored
