We investigated the familiar phenomenon of the uncanny feeling that represented people in frontal pose invariably appear to "face you" from wherever you stand. We deploy two different methods. The stimuli include the conventional one-a flat portrait rocking back and forth about a vertical axis-augmented with two novel variations. In one alternative, the portrait frame rotates whereas the actual...

This work has been motivated by the presently ongoing discussion of whether bimodality in the thermodynamic sense can be observed in fragmentation reactions and whether one can argue in favour of its providing direct evidence for the first-order character of the nuclear liquid-gas phase transition [1]. Bimodality occurs if non-negligible surface interactions at the phase boundary lead to a conv...

Abstract Effects of Glauber gluons, which cause the elastic scattering process between different jets, are studied in frame soft-collinear effective theory. modes added into action before being integrated out, is helpful studies on couplings collinear and soft particles. It proved that final state interactions cancel out for processes inclusive enough. So with light cone coordinates x + ? great...

Spectator processes which are in thermal equilibrium during the period of baryogenesis influence the final baryon asymmetry. We study this effect quantitatively for thermal leptogenesis where we find a suppression by a factor O(1). The cosmological baryon asymmetry is naturally explained by thermal leptogenesis, i.e. the out-of-equilibrium decays of heavy Majorana neutrinos [1]. This mechanism ...

Exact black hole and cosmological solutions are obtained for a special two-dimensional dilaton-spectator (φ − ψ) theory of gravity. We show how in this context any desired spacetime behaviour can be determined by an appropriate choice of a dilaton potential function V (φ) and a " coupling function " l(φ) in the action. We illustrate several black hole solutions as examples. In particular, asymp...

Drawing on a model of spectator understanding of error in performance in the literature, we document a qualitative experiment that explores the relationships between domain knowledge, mental models, intention and error recognition by spectators of performances with electronic instruments. Participants saw two performances with contrasting instruments, with controls on their mental model and und...

The dependence of inclusive weak decay rates of heavy hadrons on light spectator quarks is considered. The analysis of a previous work on relating the effects in b baryons to those in charmed baryons is extended to explicit evaluation of the matrix elements of certain four-quark operators over heavy baryons. It is shown that the usually postulated color antisymmetry of these matrix elements is ...

A study is presented examining the participatory design of digital musical interactions. The study takes into consideration the entire ecology of digital musical interactions including the designer, performer and spectator. A new instrument is developed through iterative participatory design involving a group of performers. Across the study the evolution of creative practice and skill developme...
