In this paper we shall discuss the exponential stability in mean square for a neutral stochastic diierential diierence equation of the form dx(t) ? G(x(t ?))] = f(t; x(t); x(t ?))dt + (t; x(t); x(t ?))dw(t). In the case when (t; x; y) 0 this neutral stochastic diierential diierence equations becomes a deterministic neutral diierential diierence equations d dt x(t)?G(x(t?))] = f(t; x(t); x(t?))....

Sufficiency criteria are established to ensure the asymptotic stability and boundedness of solutions to third-order nonlinear delay differential equations of the form ... x (t) + e(x(t), ẋ(t), ẍ(t))ẍ(t) + g(x(t− r), ẋ(t− r)) + ψ(x(t− r)) = p(t, x(t), x(t − r), x(t), x(t− r), x(t)). By using Lyapunov’s functional approach, we obtain two new results on the subject, which include and improve some ...

among topics in the field of pragmatics, some seem to be in a more rigorous need of investigation. pragmatic assessment and specifically the issue of pragmatic rating are among issues which deserve more thorough consideration. the purpose of this study was to examine rater criteria and its consistency and variability in the assessment of iranian efl learners’ production of compliments based on ...

The paper present some oscillation criteria for the nonlinear second-order damped delay dynamic equation ( r(t)|x∆(t)|β−1x∆(t) )∆ + p(t)|x∆σ (t)|β−1x∆σ (t) + q(t)f(x(τ(t))) = 0 on an arbitrary time scale T, where β > 0 is a constant, supT = ∞, σ(t) := inf{s ∈ T : s > t} is the forward jump operator on T, and x∆σ := x ◦ σ. Our results improve and extend some known results in which β > 0 is a quo...

Some oscillation criteria for solutions of a general ordinary differential equation of second order of the form (r(t)ψ(x(t))ẋ(t))+h(t)ẋ(t)+q(t)φ(g(x(t)),r(t)ψ(x(t))ẋ(t)) = H(t,x(t), ẋ(t)) with alternating coefficients are discussed. Our results improve and extend some existing results in the literature. Some illustrative examples are given with its numerical solutions which are computed using R...

Several oscillation criteria are established for nonlinear fractional differential equations of the form{ a(t) [( r(t)g ( D−x(t) ))′]η}′ −F(t,∫ ∞ t (v− t)−αx(v)dv ) = 0, where D−x(t) is the Liouville right-side fractional derivative of order α ∈ (0,1) of x(t),η = 2n+1 2m+1 , and n,m∈N . F(t,G)∈C([t0,∞)×R;R) , and there exists function q(t)∈ C([t0,∞);R+) such that F(t,G) Gη q(t) for G = 0 and x ...

AIMS To study the different QRS patterns in leads V1 and V2 in first inferior, lateral, and combined inferolateral myocardial infarction (MI) to recognize which are the ECG criteria that best define the presence of lesions isolated to the anatomically lateral wall of the left ventricle. METHODS AND RESULTS We studied consecutive patients with first inferior (15), lateral (9), or inferolateral...

The translocation t(8;14)(q24;q32) is the characteristic chromosomal aberration of Burkitt's-type lymphomas and leukemias (BLs). On the molecular level, the t(8;14) juxtaposes the c-myc gene in 8q24 next to the IgH locus in 14q32, resulting in overexpression of the transcription factor c-Myc. The detection of a t(8;14) is a major aim in the diagnostic process of all patients with high-grade B-c...
