Background: Sacrococcygel region is the most common site for pilonidal sinus and surgery is the most common treatment for it. Numerous operative techniques have been described for management of this disease but a technique with low recurrence and complication rates is the best treatment option. Karydakis has been introduced as a method with less recurrence rate, but it seems that surgeons debat...
The current study analyses the dynamics of the heart rate signals during specific psychological states in order to obtain a detailed understanding of the heart rate patterns during meditation. In the proposed approach, we used heart rate time series available in Physionet database. The dynamics of the signals are then analyzed before and during meditation by examining the recurrence quantificat...
Orthogonal polynomials on the unit circle are completely determined by their reflection coefficients through the Szegő recurrences. We assume that the reflection coefficients tend to some complex number a with 0 < |a| < 1. The orthogonality measure μ then lives essentially on the arc {e : α ≤ t ≤ 2π − α} where sin α 2 def = |a| with α ∈ (0, π). Under the certain rate of convergence it was prove...
In this paper, we investigate the rate of convergence of the solution uε of the random elliptic partial difference equation (∇ε∗a(x/ε, ω)∇ε + 1)uε(x, ω) = f(x) to the corresponding homogenized solution. Here x ∈ εZd, and ω ∈ Ω represents the randomness. Assuming that a(x)’s are independent and uniformly elliptic, we shall obtain an upper bound εα for the rate of convergence, where α is a consta...
purpose: to compare outcomes and recurrence rates of amniotic membrane transplantation (amt) plus intraoperative mitomycin c (mmc) and conjunctival rotational autograft (cra) plus intraoperative mmc in pterygium surgery methods: ninety-two eyes of 92 patients with primary nasal pterygium were enrolled. all patients were randomized to undergo either amt or cra. forty-three patients underwent amt...
