AIM The aim of this study was to assess the changes over time associated with salivary indices and the presence of Streptococcus mutans and Lactobacillus in patients treated with Occlus-o-Guide. MATERIALS AND METHODS Two groups of patients were evaluated: a test group of 20 patients treated with Occlus-o-Guide and a control group of 20 patients not subjected to orthodontic treatment. Both gro...

Neutral tone (T0) is a special tone form in Mandarin that contains tonal and stress information. Compared with canonical tones, T0 has a much shorter duration and reduced pitch contour. Its tonal contour is determined by the preceding canonical tone. However, not much is known about the perception of tonal and stress information in T0. In the current study, we investigate (1) whether T0 can be ...

Main Theorem. Suppose f, k, and g are real functions on R which are locally Lipschitz and p is a nonconstant, continuous, real function on [0, T ], T > 0. Also suppose all solutions of the initial value problem (1.1) can be extended to [0, T ]. If there exist real numbers a1 and a2 for which g(a1) ≤ p(t) ≤ g(a2) holds for each 0 ≤ t ≤ T , then there exists T0, 0 < T0 < T , such that if p is T0-...

We derive oscillation criteria for general-type neutral differential equations [x(t) +αx(t− τ) +βx(t+ τ)] = δ bax(t − s)dsq1(t,s) + δ ∫ d c x(t + s)dsq2(t,s) = 0, t ≥ t0, where t0 ≥ 0, δ = ±1, τ > 0, b > a ≥ 0, d > c ≥ 0, α and β are real numbers, the functions q1(t,s) : [t0,∞)× [a,b]→R and q2(t,s) : [t0,∞)× [c,d]→R are nondecreasing in s for each fixed t, and τ is periodic and continuous with ...

with given a, b, t0, t1 and n ≥ 0. This sequence was introduced by Horadam [3] in 1965, and it generalizes many sequences (see [1, 4]). Examples of such sequences are Fibonacci polynomials sequence (Fn(x))n≥0, Lucas polynomials sequence (Ln(x))n≥0, and Pell polynomials sequence (Pn(x))n≥0, when one has a = x, b = t1 = 1, t0 = 0; a = t1 = x, b = 1, t0 = 2; and a = 2x, b = t1 = 1, t0 = 0; respect...

INTRODUCTION We analyzed the changes in serum catecholamine concentrations, i.e. adrenaline and noradrenaline, in response to surgical stress in patients with pheochromocytoma who undergone videolaparoscopic adrenalectomy. MATERIALS AND METHODS Between January 1998 and March 2002, 11 patients underwent 12 videolaparoscopic adrenalectomies. In one case, the adrenalectomy was bilateral. Serum c...

Necessary and sufficient conditions for a set-valued map K : R ։ R to be GDQ-differentiable are given. It is shown that K is GDQ differentiable at t0 if and only if it has a local multiselection that is Cellina continuously approximable and Lipschitz at t0. It is also shown that any minimal GDQ of K at (t0, y0) is a subset of the contingent derivative of K at (t0, y0), evaluated at 1. Then this...

This section presents a setup that arises frequently in adverse selection settings and provides conditions on the primitives such that the properties that de…ne a game with monotone selection are satis…ed. The following de…nitions and results (in addition to those in the print appendix) are used: A correspondence : T ! X is increasing in the strong set order if when t > t0, then for each x 2 (t...
