We conducted an experiment to help resolve this apparent contradiction, and to explore whether any asymmetry exists in accuracy for maximum multiplicity validation. Results indicate an asymmetry for validation of minimum multiplicities such that accuracy is greatest when the underlying semantics represent mandatory participation.

The effect of charge hydration asymmetry (cha)—non-invariance of solvation free energy upon solute charge inversion—is missing from the standard linear response continuum electrostatics.

Masamune's rule of diastereoselectivity multiplicity explained. In a reaction between a chiral substrate and chiral reagent, their asymmetric inductions could cooperate (matched pairs) or compete (mismatched pair). According to masamune, in a matched pair the degree of asymmetric induction is approximately the product of the selectivities of the substrate and the reagent.

Abstract: the charge asymmetry ($a_\rm ch$) dependence of the $\pi^-$ and $\pi^+$ elliptic flow difference, $\delta v_2(a_\rm ch)$, has been regarded as a sensitive observable for the possible chiral magnetic wave (cmw) in relativistic heavy ion collisions. In this work, we first demonstrate that, due to non-flow backgrounds, the flow measurements by the q-cumulant method using all charged particles as reference introduce a trivial linear term to $\delta v_2(a_\rm ch)$.

The overall asymmetry is positive, but the expected asymmetry depends on the jet multiplicity and the transverse momentum of the t¯tsystem. Until recently the t¯tcross-sectionhas been calculated only at the α3 s order. Since the asymmetry only appears at this order, no full nlo treatment of this effect is available.

In nucleus-nucleus collisions, the linear dependence found for the elliptic flow harmonic of both positive or negative charged particles as a function of event charge asymmetry is predicted by the phenomenon known as the chiral magnetic wave (cmw) due to its induced electric quadrupole moment. Here, the event charge asymmetry ach is defined as n + − n − n + + n −, where n+ and n− are the number of positive and negative charged particles, respectively.
