Virasoro constraints and flavor-topology duality in QCD

We derive Virasoro constraints for the zero momentum part of the QCD-like partition functions in the sector of topological charge v. The constraints depend on the topological charge only through the combination N-f +betav/2 where the value of the Dyson index beta is determined by the reality type of the fermions. This duality between flavor and topology is inherited by the small-mass expansion of the partition function and all spectral sum rules of inverse powers of the eigenvalues of the Dirac operator. For the special case beta =2 but arbitrary topological charge the Virasoro constraints are solved uniquely by a generalized Kontsevich model with the potential V(X) = 1/X.

Collisional semiclassical approximations in phase-space representation

The Gaussian wave-packet phase-space representation is used to show that the expansion in powers of a of the quantum Liouville propagator leads, in the zeroth-order term, to results close to those obtained in the statistical quasiclassical method of Lee and Scully in the Weyl-Wigner picture. It is also verified that, propagating the Wigner distribution along the classical trajectories, the amount of error is less than that coming from propagating the Gaussian distribution along classical trajectories.

Activation function study for wavelet network

The main purpose of this paper is to investigate theoretically and experimentally the use of family of Polynomial Powers of the Sigmoid (PPS) Function Networks applied in speech signal representation and function approximation. This paper carries out practical investigations in terms of approximation fitness (LSE), time consuming (CPU Time), computational complexity (FLOP) and representation power (Number of Activation Function) for different PPS activation functions. We expected that different activation functions can provide performance variations and further investigations will guide us towards a class of mappings associating the best activation function to solve a class of problems under certain criteria.

Plane waves in noncommutative fluids

We study the dynamics of the noncommutative fluid in the Snyder space perturbatively at the first order in powers of the noncommutative parameter. The linearized noncommutative fluid dynamics is described by a system of coupled linear partial differential equations in which the variables are the fluid density and the fluid potentials. We show that these equations admit a set of solutions that are monochromatic plane waves for the fluid density and two of the potentials and a linear function for the third potential. The energy-momentum tensor of the plane waves is calculated. © 2013 Elsevier B.V.

Concepção de infância em comerciais infantis de emissora de tv aberta

With the growing market for advertising geared towards the infant public, inserting since small children in the capitalist world with his powers of persuasion, raises concerns in knowing what are the subjective messages that advertisements are transmitting to them. The television since its appearance has the power to normalize and regulate society imposing the mode of life and how they should act, think and dress. Starting this strand to analyze the influence of television on society, this work explores the current advertisements for children to check whether messages meets reality, or have an ideological conception of the world, focusing, besides consumerism, the relationship about the issue of gender of being male and being female

Relações públicas e eventos: um estudo sobre o Intercom Sudeste 2013

Based on the theoretical concepts about events, public relations and leadership, this work was developed with the aim of presenting in practical way the role of Public Relations professional in organizing events, checking his role as articulator of public interest in the cultivation of relationships. With definitions and characterization this study proposes legitimize the powers of the Public Relations event management. Beside this, the study aims to emphasize the exercise of leadership in management teams as one of the main points in the development of an event. So, the case of study develops a field research on the work of the infrastructure committee of the Southeast Intercom 2013
