Special Issue: Tsallis Entropy

open access: yesEntropy, 2012
One of the crucial properties of the Boltzmann-Gibbs entropy in the context of classical thermodynamics is extensivity, namely proportionality with the number of elements of the system.

Level statistics of real eigenvalues in non-Hermitian systems

open access: yesPhysical Review Research, 2022
Symmetries associated with complex conjugation and Hermitian conjugation, such as time-reversal symmetry and pseudo-Hermiticity, have a great impact on the eigenvalue spectra of non-Hermitian random matrices. Here, we show that time-reversal symmetry and

Ensemble equivalence for distinguishable particles [PDF]

open access: yes, 2016
Statistics of distinguishable particles has become relevant in systems of colloidal particles and in the context of applications of statistical mechanics to complex networks.

Rapidity spectra analysis in terms of non-extensive statistic approach [PDF]

open access: yesNuclear Physics B - Proceedings Supplements, 2003
We provide description of rapidity spectra of particles produced in p-anti-p collisions using anomalous diffusion approach to account for their non-equilibrium character. In particular, we exhibit connection between multiproduction processes and anomalous diffusion described through the nonlinear Focker-Planck equation with nonlinearity given by the ...

The Fate (Outcome) of Clinically Apparent Single Lesion and Oligofocal Nephroblastomatosis Treated According to SIOP/GPOH Protocols for Wilms Tumor

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Background The management of clinically apparent single lesions or oligofocal nephroblastomatosis, a facultative precursor of nephroblastoma, remains debated. Methods We retrospectively analyzed 37 patients with clinically apparent single or oligofocal nephroblastomatosis (two to three lesions per kidney) among 2347 patients registered between

Non-extensivity of the QCD pT spectra

open access: yes, 2018
We try to establish a connection between the hadronic distributions, in proton-proton collisions at very high transverse momentum $p_{\mathrm{T}}$, obtained via perturbative QCD and the Tsallis non extensive statistics.

Inpatient Food Insecurity and Pediatric Hematology Oncology Hospitalization Outcomes

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Children with cancer and blood disorders are at risk for food insecurity (FI). We aimed to describe the association of inpatient food insecurity (IFI) and hospitalization outcomes among patients admitted to the pediatric hematology oncology service. Of 325 caregivers screened for IFI, 60 (18.6%) screened positive.

Complexity theory, time series analysis and Tsallis q-entropy principle part one: theoretical aspects

open access: yesJournal of the Mechanical Behavior of Materials, 2017
In this study, we present the highlights of complexity theory (Part I) and significant experimental verifications (Part II) and we try to give a synoptic description of complexity theory both at the microscopic and at the macroscopic level of the ...

Thermodynamics and relativistic kinetic theory for q-generalized Bose–Einstein and Fermi–Dirac systems

open access: yesEuropean Physical Journal C: Particles and Fields, 2018
The thermodynamics and covariant kinetic theory are elaborately investigated in a non-extensive environment considering the non-extensive generalization of Bose–Einstein (BE) and Fermi–Dirac (FD) statistics.

Low temperature specific heat of glasses: a non-extensive approach

open access: yes, 2005
Specific heat is calculated using Tsallis statistics. It is observed that it is possible to explain some low temperature specific heat properties of glasses using non-extensive approach.
