... Let us now consider our hypothetical arbitrage example. Many Brazilian companies listed in the S˜ao Paulo Stock Ex- change also have their stocks traded on the New York Stock Exchange in the form of the so-called ... See full document

... we note the expected predominance of the A -ionic structure at small distances and of the covalent one at large distances, both of them being important at bonding distances, with close a[r] ... See full document

... We have presented the Penna model for biological age- ing and some of its most important results. Ageing is an unavoidable process (experimentally confirmed by the au- thor) and has been extensively studied by many ... See full document

... Comparing the optical model calculations without (dotted line) and with (dashed lines) the static effects of the halo, we conclude that the halo produces large enhancements of the fusion[r] ... See full document

... We also study the dis- tribution’s large velocity dependence for the cooling state and the constant energy steady-state and conclude that the results are consistent, on the correct appro[r] ... See full document

... We have therefore argued using basic features of electromagnetic theory that the lim- iting electrostatic form obtained for the effective dielectric tensor is a spurious result which doe[r] ... See full document

... We analyzed a monoclinic oxide powder sample by X-ray diffraction and refined its pattern by means of the Rietveld Method.. The crystals.[r] ... See full document

... Vol(Γ\G) denote the integral of the constant function 1 on Γ\G with respect to the G – invariant measure on Γ\G, in- duced by dx. For 0 ≤ p ≤ D − 1, the Fried trace formula [4] applied to the tensor kernel ... See full document

... The subject of all sections can be interpreted as the same, in a broad sense, namely the consequences of lacking multi- ple characteristic scales (time, size, etc) in both equilibrium st[r] ... See full document

... In the present paper electrical resistivity of simple and non-simple liquid metals have been calculated using Ziman’s formula, Ziman’s formula modified and used by Khajil and Tomak (Self[r] ... See full document

... The presence of these resistance drops for different temperatures T c in- dicates different x concentrations in the samples and that only a small fractions of the sample have the x value[r] ... See full document

... Furthermore, our calculations show that any linear theory, which does not take into account the colloidal charge renormalization, is likely to lead to an incorrect pre- diction of a liqu[r] ... See full document

... On the experimental side, perhaps the most conspicuous signal of the nearby presence of a Feshbach resonance in the pioneering experiment of Inouye et al.[3] was an enhanced loss of atoms, leading to the complete loss of ... See full document

... included in the fit. The background in channel (i,j) was em- pirically considered as proportional to the product of the total number of counts (peak excluded) along the lines j=constant by the total number ... See full document

... Considering the small number of available angular positi- ons, analytical tomographic reconstruction algorithms were discarded. Instead we have chosen a statistical iterative al- gorithm, the so-called Expectation ... See full document
