Observations concerning the magnitude of tt-bar threshold effects on electroweak parameters.
We discuss a recent analysis of tt̄ threshold effects and its implications for the determination of electroweak parameters. We show that the new formulation, when applied to the ρ parameter for mt ≈ 158 GeV, gives a result of similar magnitude to those previously obtained. In fact, it is quite close to our “resonance” calculation. We also present a simple estimate of the size of the threshold ef...

15 صفحه اولthe effects of changing roughness on the flow structure in the bends
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
Observations concerning Gödel ’ S
This article demonstrates the invalidity of Theorem VI in Gödel’s monograph of 1931, by showing that (15) xBκ(17Gen r) −→ Bewκ[Sb(r Z(x))], (16) xBκ(17Gen r) −→ Bewκ[Neg(Sb(r Z(x))], (derived by means of definition (8.1) Q(x, y) ≡ xBκ[Sb(y Z(y))] respectively from (3) R(x1, . . . , xn) −→ Bewκ[Sb(r u1...un Z(x1)...Z(xn) )], (4) R(x1, . . . , xn) −→ Bewκ[Neg(Sb(r u1...un Z(x1)...Z(xn) )], of The...
