Following the basic prescriptions of the relativistic Tsallis’ non-extensive thermostatistics, we investigate from a phenomenological point of view the relevance of non-extensive statistical effects on relativistic heavy-ion collisions observable, such as rapidity spectra of net proton production, transverse momentum distributions and transverse momentum fluctuations. Moreover, we study the nuc...
(1) The three linear terms in this equation correspond to the well-known BFKL equation. This has solutions growing like exp(ωPY ) (with ωP = 4 log(2)ᾱ) and thus violating the unitarity bound Txy ≤ 1. The last term, taking into account the scattering on both dipoles, is important when the scattering becomes of order 1 and restores unitarity. To deal with (1), one usually adopts in the mean-field...
When hadrons scatter at high energies, strong color fields, whose dynamics is described by quantum chromodynamics (QCD), are generated at the interaction point. If one represents these fields in terms of partons (quarks and gluons), the average number densities of the latter saturate at ultrahigh energies. At that point, nonlinear effects become predominant in the dynamical equations. The hadro...
Understanding the complexity of anisotropic turbulent processes over a wide range of spatiotemporal scales in engineering shear turbulence as well as climate atmosphere ocean science is a grand challenge of contemporary science with important societal impact. In such inhomogeneous turbulent dynamical systems there is a large dimensional phase space with a large dimension of unstable directions ...
DNA nanotechnology often requires collections of oligonucleotides called "DNA free energy gap codes" that do not produce erroneous crosshybridizations in a competitive muliplexing environment. This paper addresses the question of how to design these codes to accomplish a desired amount of work within an acceptable error rate. Using a statistical thermodynamic and probabilistic model of DNA code...
The equivalence between a noise source in combination with a resistance, and a thermal bath, is a part of fluctuation theory. This observation was the motivation for the author’s 1960 calculation of the power flow between modes of vibration excited by random noise sources. The resulting relation between power flow and uncoupled energy of vibration is therefore more than a thermal analogy; it is...
The High Resolution Fly's Eye (HiRes) experiment has observed the Greisen-Zatsepin-Kuzmin suppression (called the GZK cutoff) with a statistical significance of five standard deviations. HiRes' measurement of the flux of ultrahigh energy cosmic rays shows a sharp suppression at an energy of 6 x 10(19) eV, consistent with the expected cutoff energy. We observe the ankle of the cosmic-ray energy ...
In recent years, an innovative trend has been growing in applied statistics—it is becoming ever more feasible to build application-specific models which are designed to account for the hierarchical and latent structures inherent in any particular data generation mechanism. Such highly-structured models have long been advocated on theoretical grounds, but recently the development of new computat...
Statistical Energy Analysis is a statistical method in vibroacoustics entirely based on the application of energy balance that is the first principle of thermodynamics. In this study, the definition of vibrational entropy is introduced for sub-systems containing energy and modes. The rate of entropy production at interfaces between sub-systems is also derived. Finally, in steady-state condition...
