Local fields in boundary CFT
No full textConformal quantum field theory on the half-space x > 0 of Minkowski space-time (“boundary CFT”) is analyzed from an algebraic point of view, clarifying in particular the algebraic structure of local algebras and the bi-localized charge structure of local fields. The field content and the admissible boundary conditions are characterized in terms of a non-local chiral field algebra
NETS OF SUBFACTORS
No full textA subtheory of a quantum field theory specifies von Neumann subalgebras A(phi) (the 'observables' in the space-time region phi) of the von Neumann algebras B(phi) (the 'fields' localized in phi). Every local algebra being a (type III1) factor, the inclusion A(phi) subset of B(phi) is a subfactor. The assignment of these local subfactors to the space-time regions is called a 'net of subfactors'. The theory of subfactors is applied to such nets. In order to characterize the 'relative position' of the subtheory, and in particular to control the restriction and induction of superselection sectors, the canonical endomorphism is studied. The crucial observation is this: the canonical endomorphism of a single local subfactor extends to an endomorphism of the field net, which in turn restricts to a localized endomorphism of the observable net. The method allows one to characterize, and reconstruct, local extensions B of a given theory A in terms of the observables. Various non-trivial examples are given. Several results go beyond the quantum field theoretical application
A methodology for measuring intellectual capital. A structural equations modelling approach
No full textThe past decade has been characterized by a process of growing dematerialization of the strategic resources possessed by firms. The relational capabilities of the firm, technology connected with the planning and management of firm processes, know-how, as well as the decisional autonomy and technical competencies of the employees all represent intangible assets that are determining in the value creation process of a firm.
The chapter we propose describes the development and implementation of an IC measurement system within an Italian company that is leader in the agricultural food product sector. Since IC creation and development is primarily founded on the actions and capabilities of the employees, the individual employee has been used as the unit of analysis of this study. This element constitutes an innovative factor with respect to other studies which instead use MBA students or adopt the managers’ perceptions as proxy of the company they work for
The Rationality of Quaternionic Darmon Points Over Genus Fields of Real Quadratic Fields
No full textDarmon points on p-adic tori and Jacobians of Shimura curves over Q were introduced in joint articles with Rotger as generalizations of Darmon's Stark-Heegner points. In this article, we study the algebraicity over extensions of a real quadratic field K of the projections of Darmon points to elliptic curves, which coincide with the points on elliptic curves previously defined by M. Greenberg. More precisely, we prove that linear combinations of Darmon points on elliptic curves weighted by certain genus characters of K are rational over the predicted genus fields of K. This extends to an arbitrary quaternionic setting the main theorem on the rationality of Stark-Heegner points obtained by Bertolini and Darmon, and at the same time gives evidence for the rationality conjectures formulated in a joint paper with Rotger and by Greenberg in his article on Stark-Heegner points. In light of this result, quaternionic Darmon points represent the first instance of a systematic supply of points of Stark-Heegner type other than Darmon's original ones for which explicit rationality results are known. © 2013 The Author(s) 2013.

Going Beyond Counting First Authors in Author Co-citation Analysis
No full textThe present study examines one of the fundamental aspects of author co-citation analysis (ACA) - the way co-citation
counts are defined. Co-citation counting provides the data on which all subsequent statistical analyses and mappings
are based, and we compare ACA results based on two different types of co-citation counting - the traditional type that
only counts the first one among a cited work's authors on the one hand and a non-traditional type that takes into
account the first 5 authors of a cited work on the other hand. Results indicate that the picture produced through this non-traditional author co-citation counting contains more coherent author groups and is therefore considerably clearer. However, this picture represents fewer specialties in the research field being studied than that produced through the traditional first-author co-citation counting when the same number of top-ranked authors is selected and analyzed. Reasons for these effects are discussed
HFO1234yf Condensation Inside A Brazed Plate Heat Exchanger
No full textThis paper presents the heat transfer coefficients and the pressure drop measured during HFO1234yf condensation inside a brazed plate heat exchanger: the effects of saturation temperature, refrigerant mass flux and vapour superheating are investigated. The heat transfer coefficients show weak sensitivity to saturation temperature and great sensitivity to refrigerant mass flux. At low refrigerant mass flux (\u3c 20 kg/m2s) the heat transfer coefficients are not dependent on mass flux and condensation is controlled by gravity. For higher refrigerant mass flux (\u3e 20 kg/m2s) the heat transfer coefficients depend on mass flux and forced convection condensation occurs. The condensation heat transfer coefficients of super-heated vapour are from 8 to 11% higher than those of saturated vapour. The frictional pressure drop shows a linear dependence on the kinetic energy per unit volume of the refrigerant flow and therefore a quadratic dependence on the refrigerant mass flux. HFO1234yf exhibits heat transfer coefficients lower (10-12%) and frictional pressure drop lower (10-20%) than those of HFC134a under the same operating conditions
