the biological effects of omega-3 and omega-6 fatty acids are determined by their mutual interactions. this interaction extremely affects various functions. lower consumption of omega-3 during gestation leads to various disorders, even in hearing. we aimed to assess the effect of low omega-3/omega-6 ratios on auditory nerve conduction. in this experimental study, the auditory brainstem response...

In the ear, hair cells transform mechanical stimuli into neuronal signals with great sensitivity, relying on certain active processes. Individual hair cell bundles of non-mammals such as frogs and turtles are known to show spontaneous oscillation. However, hair bundles in vivo must be quiet in the absence of stimuli, otherwise the signal is drowned in intrinsic noise. Thus, a certain mechanism ...

We study the finite-size corrections of the critical dense polymer (CDP) and the dimer models on ∞×N rectangular lattice. We find that the finite-size corrections in the CDP and dimer models depend in a crucial way on the parity of N, and a change of the parity of N is equivalent to the change of boundary conditions. We present a set of universal amplitude ratios for amplitudes in finite-size c...

The leading excitations of the dilute AL model in regime 2 are considered using analytic arguments. The model can be identified with the integrable φ1,2 perturbation of the unitary minimal series ML,L+1. It is demonstrated that the excitation spectrum of the transfer matrix satisfies the same functional equations in terms of elliptic functions as the exact S-matrices of the φ1,2 perturbation do...

Motivated by the results of two-dimensional conformal field theory (CFT) we investigate the finite-size scaling of the mass spectrum of an Ising model on three-dimensional lattices with a spherical cross section. Using a cluster-update Monte Carlo technique we find a linear relation between the masses and the corresponding scaling dimensions, in complete analogy to the situation in two dimensio...

Let f(N) and xi(-1)(N) represent, respectively, the free energy per spin and the inverse spin-spin correlation length of the critical Ising model on a N x infinity lattice, with f(N)-->f(infinity) as N-->infinity. We obtain analytic expressions for a(k) and b(k) in the expansions N( f(N)-f(infinity)) = SUM (k = 1)(infinity)a(k)/N(2k-1) and xi(-1)(N) = SUM (k = 1)(infinity)b(k)/N(2k-1) for squar...

In recent years, numerous regional seismic event discrimination studies have shown that the high-frequency (usually greater than 3–4 Hz), P/S spectral amplitude ratios of regional P (Pg or Pn) and S (Sg, Sn or Lg) waves observed at distance range from few kilometers up to about 2,000 kilometers, provide an efficient method to classify regional earthquakes, quarry blasts and underground nuclear ...
