begin{abstract} in this paper, we prove some strong and weak convergence of three step random iterative scheme with errors to common random fixed points of three asymptotically nonexpansive nonself random mappings in a real uniformly convex separable banach space. end{abstract}
The period from 1979 to 1983 represented, in more ways than one, a nadir for the Labour Party. The 1974-9 government was brought down on a vote of no confidence following a winter of industrial action. Many felt that Callaghan should have called the election in late 1978, when Labour’s electoral prospects seemed better, and in hindsight it appears difficult to disagree. Nonetheless, on May 3, 1...
In a recent paper, Lee and Moharrami [13] construct a family of metrics (Xn, dn) with |Xn| = N , such that (Xn, √ dn) embeds into L2 with constant distortion, but embedding (Xn, dn) into a metric of negative type requires distortion Ω̃(log 1N). In this paper, we build on their analysis, and improve their result by showing an Ω̃(log 1N) lower bound for embedding (Xn, dn) into a metric of negative ...
Using a new s-nucleosynthesis code coupled with the stellar evolution code Star2003, simulations have been performed to study the impact of the convection treatment on the s-process during core He-burning of a 25 M⊙ star (ZAMS mass) with an initial metallicity of Z=0.02. Particular attention has been devoted to the impact of the extent of overshooting on the s-process efficiency. The results sh...
It has been shown that, from the prevalence point of view, elements of the S spaces are almost surely multifractal, while the Hölder exponent at almost every point is almost surely equal to the maximum Hölder exponent. We show here that typical elements of S are very irregular by proving that they almost surely satisfy a weak irregularity property: there exists a local irregularity exponent whi...
It is well known that S1 2 cannot prove the injective weak pigeonhole principle for polynomial time functions unless RSA is insecure. In this note we investigate the provability of the surjective (dual) weak pigeonhole principle in S1 2 for provably weaker function classes. §
Using a new s-nucleosynthesis code coupled with the stellar evolution code Star2003, simulations have been performed to study the impact of convection treatment on the s-process during core He-burning of a 25 M⊙ star (ZAMS mass) with initial solar metallicity. A diffusive approach, with the diffusion constant proportional to the convective velocity obtained from the mixing length theory, has be...
The weak s process takes place in massive stars and it produces the majority of s-only isotopes in the atomic mass range from 60 to 90. This process is qualitatively well understood. However, there are still large uncertainties remaining on the quantitative side. Rotation has a strong effect on the stellar structure and mixing, but its impact on the s process has not been studied yet. We implem...
this article employs a combination of direct observation method, online survey and focus group discussion techniques in order to study how social capital takes shape among youth facebook users in iran. this article, will also, attempt to answer the question of whether the social capital that takes its roots from interaction between facebook users and friends' circles, will also reflect on...
We report the detection in the X rays of two weak Seyfert 2’s (NGC3393 and NGC4941) with the Italian–Dutch satellite BeppoSAX. These are among the first sources observed in a sample of 12 Seyfert 2’s which are being studied within the BeppoSAX core program, in an effort to probe the putative torus at high X-ray energies, calibrate an isotropic luminosity indicator for absorbed nuclei, and deter...
