The present analysis indicates that the probability of recurrence of a single walker, the long time behavior of the time-dependent concentration for the annihilating random walks and the stationary concentration for the BARW in the limit P → 0 are strongly related to each other.

In other words, the osmotic coefficient develops a weak logarithmic concentration dependence. (If the cylinders were not completely hollow an extra concentration dependence would appear at high concentrations.
Osmotic Properties of Charged Cylinders: Critical Evaluation of Counterion Condensation Theory
In the low-concentration range and 2 mM salt the calculated pressures are slightly too large which might in part reflect a weak contribution from finite salt concentration that can be dealt with on the basis of a simple Donnan equilibrium picture [4, 12, 3].

In the high-concentration range, the calculated variation of the pressure with concentration is clearly slower than what one observes for the experimental data.

Talagrand’s theorem was first applied in the context of random matrices by Guionnet and Zeitouni , who used it to prove a concentration result for the spectral measure of selfadjoint random matrices, and who also remarked that the same methods give concentration results for other functionals of self-adjoint matrices.
Concentration of norms and eigenvalues of random matrices
Since concentration of the kind in the inequality (7) about any value implies concentration about a median (with a possibly different function f ), no such concentration result holds for S 1/p n when 1 ≤ p < 2.
Concentration of norms and eigenvalues of random matrices
Guionnet and Zeitouni were the first to note that this concentration theorem implies normal concentration for any function on matrices (or self-adjoint matrices) which is convex and Lipschitz with respect to the Hilbert-Schmidt norm.
