—Geographic ranges of widespread Andean forest bird species are linear, averaging over 300 times longer than they are wide. Among congeneric species, geographic variation in plumage was negatively correlated to the width (W) of their elevational distributions, presumably because narrower distributions are more easily fragmented by barriers to gene flow. The amplitude of a species' elevational d...

The given article example of physical analogies to be entered information space-time. The opportunity of Poincare group use is shown for transition from one frame in another, for this purpose is entered invariant velocity of transition of the information. For calculation of information processes probability amplitudes is offered using path integral of Feynman.

We discuss calculations of three-body observables for the breakup of B on a Ni target at low energy using the coupled discretized continuum channels approach. Calculations of both the angular distribution of the Be fragments and their energy distributions are compared with those measured at several laboratory angles. In these observables there is interference between the breakup amplitudes from...

The need for cross-cultural studies of disability has often been stated but seldom acted upon. It was nearly thirty years ago that Edgerton, in a highly influential paper, made the intellectual case for increased study of disability within and between societies, both developing and developed (Edgerton 1970). His hope that such studies would soon be undertaken has not been borne out (Manion & Be...

and refer to [2] and [3] for more background information. Here, M is the wanted eigenvalue of the invariant mass squared operator, with associated eigenfunction ψ ≡ Ψqq̄. It is the probability amplitude for finding in the qq̄–space a quark with the effective (constituent) mass m1, longitudinal momentum fraction x, transversal momentum ~k⊥ and helicity λ1, and correspondingly for the anti– quark w...

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...

By employing recent data on non-mesonic decay of s-shell Λ-hypernuclei we study, within the phenomenological model of Block and Dalitz, the validity of the ∆I = 1/2 rule in the ΛN → N N process. Due to the low experimental precision, a possible violation of this rule can be neither proved nor excluded at present with sufficient accuracy: a pure ∆I = 1/2 transition amplitude is excluded at 40% c...

The solution to the Balitsky-Kovchegov equation is found in the deep saturation domain. The controversy between different approaches regarding the asymptotic behaviour of the scattering amplitude is solved. It is shown that the dipole amplitude behaves as 1− exp (−z + ln z) with z = ln(rQs) (r -size of the dipole, Qs is the saturation scale) in the deep saturation region. This solution is devel...

It is argued that a spontaneous vortex phase may exist in the recently discovered compound ErN i 2 B 2 C at temperature below 2.3K. The consequences of this proposal are discussed. In particular the magnetic response of the system are studied both above and below 2.3K and further experiments proposed.

We discuss the assessment of breakdown probabilities by means of the up-and-down method. The exact maximum likelihood estimates for a number of response patterns are calculated for three different distribution functions and are compared with the estimates corresponding to the normal distribution. Estimates of the 50% probability breakdown voltage and of the scale parameter of the breakdown prob...
