Metcalfe's law and log-period power laws in the cryptocurrencies market

open access: yesEconomics: Journal Articles, 2019
In this paper the authors investigate the statistical properties of some cryptocurrencies by using three layers of analysis: alpha-stable distributions, Metcalfe’s law and the bubble behaviour through the LPPL modelling.

Structural and magnetic properties of small symmetrical and asymmetrical sized fullerene dimers [PDF]

open access: yesMaterial Research Express 5 (2018) 016105, 2020
Magnetism in carbon nanostructures is of high scientific interest, which could lead to novel magnetic materials. The magnetic properties of symmetrical and asymmetrical sized small fullerene dimers have been investigated using spin polarized density functional theory.

Nuclear charm and bottom production: a comparison among high energy approaches [PDF]

open access: yesEur.Phys.J.C32:501-506,2004, 2003
We calculate the nucleon and nuclear photoproduction cross sections for heavy quarks within the $k_{\perp}$-factorization formalism, considering the current high energy approaches which include nuclear and saturation effects. Our results demonstrate that a future experimental analysis of this process would allow to constraint the QCD dynamics at high ...

Crystal structures of eight mono-methyl alkanes (C26–C32) via single-crystal and powder diffraction and DFT-D optimization

open access: yesIUCrJ, 2015
The crystal structures of eight mono-methyl alkanes are solved from powder or single-crystal X-ray diffraction data, and optimized via DFT-D calculations.

An investigation of the price discovery role of futures markets: A dynamic time warping analysis of the United States corn markets

open access: yesAgribusiness, EarlyView.
Abstract Futures markets are critical to price discovery and often dominate spot markets. We analyze the linkages between daily corn futures and spot prices in the United States using dynamic time warping. This nonparametric pattern recognition technique has several advantages over traditional time series methods.

A Truly Minimal Left-Right Symmetric Extension of the Standard Model [PDF]

open access: yesEur.Phys.J.C32:555,2004, 2003
By invoking the existence of a general custodial O(2) symmetry, a minimal Left-Right symmetric model based on the gauge group G=SU(2)L SU(2)R U(1)BL is shown to require the existence of only two physical Higgs bosons. The lighter Higgs is predicted to have a small mass which could be evaluated by standard perturbation theory.

Conditions for Confinement and Freeze-Out [PDF]

open access: yesEur.Phys.J. C32 (2003) 115-119, 2003
Matter implies the existence of a large-scale connected cluster of a uniform nature. The appearance of such clusters as function of hadron density is specified by percolation theory. We can therefore formulate the freeze-out of interacting hadronic matter in terms of the percolation of hadronic clusters.
