Hidden Markov Models for Longitudinal Rating Data with Dynamic Response Styles

R. Colombi, S. Giordano, M. Kateri

This work deals with the analysis of longitudinal ordinal responses. The novelty of the proposed approach is in modeling simultaneously the temporal dynamics of a latent trait of i…

Higgs production in the high-energy limit of pQCD

Francesco Giovanni Celiberto, Michael Fucilla, Dmitry Yu. Ivanov +2

With the advent of TeV-energy colliding machines, such as the Large Hadron Collider (LHC), the possibility has opened up to test predictions of Quantum Chromodynamics (QCD) and, mo…

Reducing the impact of out of vocabulary words in the translation of natural language questions into SPARQL queries

Manuel A. Borroto Santana, Francesco Ricca, Bernardo Cuteri

Accessing the large volumes of information available in public knowledge bases might be complicated for those users unfamiliar with the SPARQL query language. Automatic translation…

Heavy-flavored emissions in hybrid collinear/high-energy factorization

Andrèe Dafne Bolognino, Francesco Giovanni Celiberto, Michael Fucilla +2

Heavy-flavored emissions have been always considered as an excellent channel to test properties of Quantum chromodynamics (QCD) at present and future colliders. Among different reg…

The pyglaf argumentation reasoner (ICCMA2021)

Mario Alviano

The pyglaf reasoner takes advantage of circumscription to solve computational problems of abstract argumentation frameworks. In fact, many of these problems are reduced to circumsc…

Aliasing Instabilities in the Numerical Evolution of the Einstein Field Equations

Claudio Meringolo, Sergio Servidio

The Einstein field equations of gravitation are characterized by cross-scale, high-order nonlinear terms, representing a challenge for numerical modeling. In an exact spectral deco…

Understanding the growth of the Fediverse through the lens of Mastodon

Lucio La Cava, Sergio Greco, Andrea Tagarelli

Open-source, Decentralized Online Social Networks (DOSNs) are emerging as alternatives to the popular yet centralized and profit-driven platforms like Facebook or Twitter. In DOSNs…

Group theoretical derivation of consistent massless particle theories

Giuseppe Nisticò

Current theories of massless free particle assume {\sl unitary} space inversion and {\sl anti-unitary} time reversal operators. In so doing robust classes of possible theories are…

A mixed-frequency approach for exchange rates predictions

Raffaele Mattera, Michelangelo Misuraca, Germana Scepi +1

Selecting an appropriate statistical model to forecast exchange rates is still today a relevant issue for policymakers and central bankers. The so-called Meese and Rogoff puzzle as…

Dissipative cooling induced by pulse perturbations

Andrea Nava, Michele Fabrizio

We investigate the dynamics brought on by an impulse perturbation in two infinite-range quantum Ising models coupled to each other and to a dissipative bath. We show that, if dissi…

Approximate solutions of the Schrodinger equation with Hulthen-Hellmann Potentials for a Quarkonium system

I. O. Akpan, E. P. Inyang, E. S. William

Hulthén plus Hellmann potentials are adopted as the quark-antiquark interaction potential for studying the mass spectra of heavy mesons. We solved the radial Schrödinger equation a…
