A microscopic treatment of cumulative phenomena based on perturbative QCD calculations of the corresponding quark diagrams near the threshold is presented. To sum all diagrams like these the special technique based on the recurrence relations was developed. The x-behaviour of the nuclear structure function F2(x) in the cumulative region x > 1 was found to be roughly exponential, governed by an ...

If NMR systems are to be used as practical quantum computers, the number of coupled spins will need to be so large that it is not feasible to rely on purely heteronuclear spin systems. The implementation of a quantum logic gate imposes certain constraints on the motion of those spins not directly involved in that gate, the so-called “spectator” spins; they must be returned to their initial stat...

The phenomenon of isoscaling is receiving considerable interest because of its relation with the symmetry term in statistical [1] and dynamical [2] descriptions of fragmentation reactions. As reported recently, the symmetry term coefficient γ in the liquid-drop description of the nascent fragments appears to be decreasing from the standard value γ = 25 MeV for isolated nuclei to about 15 MeV or...

The essay examines the intersection between aesthetic the-ory and representations of city in periodical Spectator (1711-1714). Focusing on this allows for an analysis cultural work pleasure is supposed to do according Spectator, also shows key differenc-es “spectatorial” later, Kantian aesthetics. In has with producing a model how one should relate realm politics—rather than disin-terest, preco...

Abstract We argue that double inflation may occur when a spectator field is non-minimally coupled to gravity. As concrete example, we study two-field inflationary model where the initial gravity while inflaton minimally coupled. The non-minimal coupling results in growth of which, turn, drives second stage significant region parameter space. isocurvature fluctuations originating from source adi...

We report the methyl radical product state distributions for the reactions of H and Cl with CHD3(nu1 = 1,2) at collision energies of 1.53 and 0.18 eV, respectively. Both reactions demonstrate mode selectivity. The resulting state distributions from the H+CHD3(nu1 = 1,2) reactions are well described by a spectator model. The reactions Cl + CHD3(nu1 = 1,2) exhibit similar behavior, but in some as...

Recent developments in various branches of political science underscore the importance of empirical investigation of impartial views. This paper proposes and tests an empirical model of impartiality, inspired by Adam Smith (1759), that is based on the moral judgments of informed third parties (or spectators). The model predicts that spectatorship produces properties widely considered desirable ...

We present the calculation of the next-to-leading corrections to the tree amplitudes which appear in the description of non-leptonic B-decays in the factorization approach. These corrections, together with radiative corrections to the jet functions, represent the full next-to-leading contributions to the dominant hard spectator scattering term generated by operators O1,2 in the decay amplitudes...

In this thesis I try to answer the question of how information spaces can be designed so that they support humans in the exploration of a large set of scientific literature items. I will argue that the degree of support increases if the spatial representation assembles the mental representation of a certain spectator. In this regard, I will illustrate how humans build such mental representation...
