Distributions In The Discrete Cohen Classes
, 2008 The Cohen class of time-frequency distributions for continuous signals has recently been to extended to discrete signals using both an axiomatic approach and an operator theory approach.

Competing methods for representing random taste heterogeneity in discrete choice models [PDF]
This paper reports the findings of a systematic study using Monte Carlo experiments and a real dataset aimed at comparing the performance of various ways of specifying random taste heterogeneity in a discrete choice model.

Reeh-Schlieder defeats Newton-Wigner: On alternative localization schemes in relativistic quantum field theory [PDF]
, 2000 Many of the "counterintuitive" features of relativistic quantum field theory have their formal root in the Reeh-Schlieder theorem, which in particular entails that local operations applied to the vacuum state can produce any state of the entire

Combining discrete and continuous mixing approaches to accommodate heterogeneity in price sensitivities in environmental choice analysis [PDF]
Data from a discrete choice experiment aimed at eliciting the demand for recreational walking trails on farmland in the Republic of Ireland is used to explore the consequences of misspecifying the cost coefficient.

Gluon Wigner distributions in a light-cone spectator model
, 2023 We study the gluon Wigner distributions of the proton which are the phase-space distributions containing the most general one-parton information. Using the proton wave functions deduced from a light-cone spectator model that contains the gluonic degree ...

, 2018 In this paper, we propose a new method to estimate instantaneous frequency using a combined approach based on the discrete linear chirp transform (DLCT) and the Wigner distribution (WD). The DLCT locally represents a signal as a superposition of linear chirps while the WD provides maximum energy concentration along the instantaneous frequency in the ...

Quark Wigner distributions in a light-cone spectator model
, 2015 We investigate the quark Wigner distributions in a light-cone spectator model. The Wigner distribution, as a quasidistribution function, provides the most general one-parton information in a hadron. Combining the polarization configurations, unpolarized,

Wigner Distributions in Light-Front Quark Models
, 2014 We discuss the quark Wigner distributions which represent the quantum-mechanical analogues of the classical phase-space distributions. These functions can be obtained through a Fourier transform in the transverse space of the generalized transverse ...

Discrete Wigner Function Derivation of the Aaronson–Gottesman Tableau Algorithm
, 2017 The Gottesman–Knill theorem established that stabilizer states and Clifford operations can be efficiently simulated classically. For qudits with odd dimension three and greater, stabilizer states and Clifford operations have been found to correspond to ...

Estimation de la fréquence instantanée des signaux FM par opérateur d'énergie Psi_B [PDF]
, 2011 Psi_B energy operator is an extension of the cross Teager-Kaiser energy operator which is an non-linear energy tracking operator to deal with complex signals and its usefulness for non-stationary signals analysis has been demonstrated. In this letter two
