Italian National Conference on Sensors, 2018 To cope with the complex electromagnetic environment and varied signal styles, a novel method based on the energy cumulant of short time Fourier transform and reinforced deep belief network is proposed to gain a higher correct recognition rate for radar ...

Lattice QCD results on cumulant ratios at freeze-out [PDF]
, 2016 Ratios of cumulants of net proton-number fluctuations measured by the STAR Collaboration show strong deviations from a skellam distribution, which should describe thermal properties of cumulant ratios, if proton-number fluctuations are generated in ...

Hyperscaling breakdown and Ising Spin Glasses: the Binder cumulant
, 2017 Among the Renormalization Group Theory scaling rules relating critical exponents, there are hyperscaling rules involving the dimension of the system. It is well known that in Ising models hyperscaling breaks down above the upper critical dimension.

QCD θ-vacuum in a uniform magnetic field
Nuclear Physics B, 2022 We study the θ-vacuum of QCD using two-flavor chiral perturbation theory (χPT) in the presence of a uniform, background magnetic field calculating the magnetic field-dependent free energy density, the topological density, the topological susceptibility ...

Cumulant Expansions and the Spin-Boson Problem
, 1996 The dynamics of the dissipative two-level system at zero temperature is studied using three different cumulant expansion techniques. The relative merits and drawbacks of each technique are discussed.

Net baryon number fluctuations across the chiral phase transition at finite density in the strong coupling lattice QCD [PDF]
, 2015 We investigate the net-baryon number fluctuations across the chiral phase transition at finite density in the strong coupling and chiral limit. Mesonic field fluctuations are taken into account by using the auxiliary field Monte-Carlo method.

Modelling of continuous low‐temperature emulsion co‐polymerization in 3D‐printed reactor
The Canadian Journal of Chemical Engineering, EarlyView.A kinetic model for the emulsion copolymerization of butyl acrylate/styrene at low temperatures is proposed and validated against experiments with a redox initiator system. The model was successfully transferred to a 3D‐printed tubular reactor and conversions of more than 80% and small particles sizes below 40 nm were observed.

Topological susceptibility and fourth cumulant in a uniform magnetic field
Nuclear Physics B, 2022 We study the topological susceptibility and fourth cumulant of the QCD vacuum in a background magnetic field (H) using three-flavor chiral perturbation theory (χPT) for arbitrary quark masses and n-flavor χPT with degenerate quark masses.

Cumulant ratios and their scaling functions for Ising systems in strip geometries
, 1999 We calculate the fourth-order cumulant ratio (proposed by Binder) for the two-dimensional Ising model in a strip geometry L x oo. The Density Matrix Renormalization Group method enables us to consider typical open boundary conditions up to L=200 ...

Measuring non-Gaussian fluctuations through incoherent Cooper pair current [PDF]
, 2004 We study a Josephson junction (JJ) in the regime of incoherent Cooper pair tunneling, capacitively coupled to a nonequilibrium noise source. The current-voltage (I-V) characteristics of the JJ are sensitive to the excess voltage fluctuations in the ...
