The rings of (2060) Chiron: Evidence of an evolving system
C. L. Pereira, F. Braga-Ribas, B. Sicardy +54
The centaur (2060) Chiron has long been a candidate for hosting material in orbit, based on occultation and photometric and spectroscopic data. Here, we present a multichord stella…
Forced silo discharge: Simulation and theory
Luis. A. Pugnaloni, Marcos A. Madrid, J. R. Darias
We study, through discrete element simulations, the discharge of granular materials through a circular orifice on the base of a cylindrical silo forced by a surcharge. At the begin…
Flow rate from a vertical silo with a tilted orifice
Ryan Kozlowski, Luis A. Pugnaloni
The flow of dry granular materials from silos is of great practical interest in industry and of theoretical import for understanding multiphase dynamics. Recent studies have demons…
Extension of the Best Polynomial Operator in Generalized Orlicz spaces
Sonia Acinas, Sergio Favier, Rosa Lorenzo
In this paper, we consider the best multivalued polynomial approximation operator for functions in an Orlicz Space . We obtain its characterization involving and $ψ^+…
Intruder in a two-dimensional granular system: statics and dynamics of force networks in an experimental system experiencing stick-slip dynamics
R. Basak, R. Kozlowski, L. A. Pugnaloni +4
In quasi-two-dimensional experiments with photoelastic particles confined to an annular region, an intruder constrained to move in a circular path halfway between the annular walls…
Average outpouring velocity and flow rate of grains discharged from a tilted quasi-2D silo
Ryan Kozlowski, J. Carter Luketich, Elijah Oshatz +2
The flow of granular materials through constricted openings is important in many natural and industrial processes. These complex flows - featuring dense, dissipative flow in the bu…
Designing Quality Requirements, Metrics and Indicators for Core Ontologies: Results of a Comparative Study for Process Core Ontologies
Luis Olsina, Maria Fernanda Papa, Guido Tebes +1
This preprint specifies quality requirements for a core ontology whose ontological elements such as terms, non-taxonomic relationships, among others, are based on a foundational on…
Dynamics of flowing 2D skyrmions
Rodrigo C. V. Coelho, Mykola Tasinkevych, Margarida M. Telo da Gama
We investigate, numerically, the effects of externally imposed material flows on the structure and temporal evolution of liquid crystal skyrmions. The dynamics of a 2D system of sk…
SituationCO v1.2's Terms, Properties, Relationships and Axioms -- A Core Ontology for Particular and Generic Situations
Luis Olsina, Guido Tebes, Pablo Becker
The current preprint is an update to SituationCO v1.1 (Situation Core Ontology), which represents its new version 1.2. It specifies and defines all the terms, properties, relations…
Enhancement of the flow of vibrated grains through narrow apertures by addition of small particles
Marcos A. Madrid, C. Manuel Carlevaro, Luis A. Pugnaloni +2
We analyze the flow and clogging of circular grains passing through a small aperture under vibration in two dimensions. Via Discrete Element Method simulations, we show that when g…
Two approaches to quantification of force networks in particulate systems
Rituparna Basak, C. Manuel Carlevaro, Ryan Kozlowski +6
The interactions between particles in particulate systems are organized in `force networks', mesoscale features that bridge between the particle scale and the scale of the system a…
Differential equation for the flow rate of discharging silos based on energy balance
J. R. Darias, Marcos A. Madrid, Luis A. Pugnaloni
Since the early work of Hagen in 1852 and Beverloo et al. in 1961, the flow rate of granular material discharging through a circular orifice from a silo has been described by means…
Intruder in a two-dimensional granular system: Effects of dynamic and static basal friction on stick-slip and clogging dynamics
C. Manuel Carlevaro, Ryan Kozlowski, Luis A. Pugnaloni +3
We discuss the results of simulations of an intruder pulled through a two-dimensional granular system by a spring, using a model designed to lend insight into the experimental find…
Dynamics of a grain-scale intruder in a two-dimensional granular medium with and without basal friction
Ryan Kozlowski, C. Manuel Carlevaro, Karen E. Daniels +5
We report on a series of experiments in which a grain-sized intruder is pushed by a spring through a 2D granular material comprised of photoelastic disks in a Couette geometry. We…
Quantum treatment of Verlinde's entropic force conjecture
A. Plastino, M. C. Rocca, G. L. Ferri
Verlinde conjectured that gravitation is an emergent entropic force. This surprising conjecture was proved in [Physica A {\bf 505} (2018) 190] within a purely classical context. He…
Dimensionally regularized Boltzmann-Gibbs Statistical Mechanics and two-body Newton's gravitation
D. J. Zamora, M. C. Rocca, A. Plastino +1
It is believed that the canonical gravitational partition function associated to the classical Boltzmann-Gibbs (BG) distribution cannot be constructe…
Dimensionally regularized Tsallis' Statistical Mechanics and two-body Newton's gravitation
J. D. Zamora, M. C. Rocca, A. Plastino +1
Typical Tsallis' statistical mechanics' quantifiers like the partition function and the mean energy exhibit poles. We are speaking of the partition function and the mean…
Statistical complexity without explicit reference to underlying probabilities
F. Pennini, A. Plastino
We show that extremely simple systems of a not too large number of particles can be simultane- ously thermally stable and complex. To such an end, we extend the statistical complex…
Reply to "Comment on "Troublesome aspects of the Renyi-MaxEnt treatment""
A. Plastino, M. C. Rocca, F. Pennini
This Reply is intended as a refutation of the preceding Comment [Oikonomou and Bagci, Phys. Rev. E 96, 056101 (2017)] on our paper [Plastino et al., Phys. Rev. E 94, 012145 (2016).…
Verlinde's emergent gravity in an dimensional, non-additive Tsallis' scenario
D. J. Zamora, M. C. Rocca, A. Plastino +1
This paper brings together four distinct but very important physical notions: 1) Entropic force, 2) Entropy-along-a-curve, 3) Tsallis' q-statistics, and 4) Emergent gravitation. We…
Dimensional Regularization of Renyi's Statistical Mechanics
A. Plastino, M. C. Rocca
We show that typical Renyi's statistical mechanics' quantifiers exhibit poles. We are referring to the partition function and the mean energy . Renyi's entro…
Statistical manifestation of quantum correlations via disequilibrium
F. Pennini, A. Plastino
That of disequilibrium (D) is a statistical notion introduced by López-Ruiz, Mancini, and Calbet (LMC) more than 20 years ago [Phys. Lett. A 209 (1995) 321]. D measures the amount…
Selfextensional logics with a distributive nearlattice term
Luciano J. González
We define when a ternary term of an algebraic language is called a \textit{distributive nearlattice term} (DN-term) of a sentential logic . Distribut…
q-Path entropy phenomenology for phase-space curves
D. J. Zamora, M. C. Rocca, A. Plastino +1
We describe the phenomenology of the classical q-path entropy of a phase-space curve. This allows one to disclose an entropic force-like mechanism that is able to mimic some phenom…
