Sustainable Visions: Unsupervised Machine Learning Insights on Global Development Goals

Autor: García-Rodríguez, Alberto, Núñez, Matias, Pérez, Miguel Robles, Govezensky, Tzipe, Barrio, Rafael A., Gershenson, Carlos, Kaski, Kimmo K., Tagüeña, Julia

The United Nations 2030 Agenda for Sustainable Development outlines 17 goals to address global challenges. However, progress has been slower than expected and, consequently, there is a need to investigate the reasons behind this fact. In this study,

Magnetic structure and component-separated transitions of HoNiSi$_{3}$

Autor: Tartaglia, R., Arantes, F. R., Galdino, C. W., Kaneko, U. F., Avila, M. A., Granado, E., Vildosola, Veronica, Nuñez, Matias, Cornaglia, Pablo S., García, Daniel J.

Publikováno v: Phys. Rev. B \textbf{109}, 144402 (2024)

HoNiSi$_{3}$ is an intermetallic compound characterized by two successive antiferromagnetic transitions at $T_{N1} = 6.3$ K and $T_{N2} = 10.4$ K. Here, its zero-field microscopic magnetic structure is inferred from resonant x-ray magnetic diffractio

Unveiling Exotic Magnetic Phases in Fibonacci Quasicrystalline Stacking of Ferromagnetic Layers through Machine Learning

Autor: Cornaglia, Pablo S., Nuñez, Matias, Garcia, D. J.

In this study, we conduct a comprehensive theoretical analysis of a Fibonacci quasicrystalline stacking of ferromagnetic layers, potentially realizable using van der Waals magnetic materials. We construct a model of this magnetic heterostructure, whi

Price & Choose

Autor: Echenique, Federico, Núñez, Matías

We describe a two-stage mechanism that fully implements the set of efficient outcomes in two-agent environments with quasi-linear utilities. The mechanism asks one agent to set prices for each outcome, and the other agent to make a choice, paying the

An axiomatic derivation of Condorcet-consistent social decision rules

Autor: Yonta, Aurelien Mekuko, Núñez, Matias, Moyouwou, Issofa, Andjiga, Nicolas Gabriel

A social decision rule (SDR) is any non-empty set-valued map that associates any profile of individual preferences with the set of (winning) alternatives. An SDR is Condorcet-consistent if it selects the set of Condorcet winners whenever this later i
