Multiset semantics in SPARQL, Relational Algebra and Datalog
Renzo Angles, Claudio Gutierrez, Daniel Hernández
The paper analyzes and characterizes the algebraic and logical structure of the multiset semantics for SPARQL patterns involving AND, UNION, FILTER, EXCEPT, and SELECT. To do this,…
MRSeqStudio: MRI Sequence Design and Simulation as a Service in a Free and Open-Source Web Platform
Pablo Villacorta-Aylagas, Manuel Rodríguez-Cayetano, Carlos Castillo-Passi +3
MRI sequence prototyping increasingly relies on graphical design environments and numerical simulators to accelerate development and validation. While several platforms support int…
Automated Labeling of Intracranial Arteries with Uncertainty Quantification Using Deep Learning
Javier Bisbal, Patrick Winter, Sebastian Jofre +10
Accurate anatomical labeling of intracranial arteries is essential for cerebrovascular diagnosis and hemodynamic analysis but remains time-consuming and subject to interoperator va…
Studying stellar populations in Omega Centauri with phylogenetics
P. Jofré, C. Aguilera-Gómez, P. Villarreal +14
The nature and formation history of our Galaxy's largest and most enigmatic stellar cluster, known as Omega Centauri (ocen) remains debated. Here, we offer a novel approach to dise…
Fairness in LLM-Generated Surveys
Andrés Abeliuk, Vanessa Gaete, Naim Bro
Large Language Models (LLMs) excel in text generation and understanding, especially in simulating socio-political and economic patterns, serving as an alternative to traditional su…
Generative artificial intelligence in dentistry: Current approaches and future challenges
Fabián Villena, Claudia Véliz, Rosario García-Huidobro +1
Artificial intelligence (AI) has become a commodity for people because of the advent of generative AI (GenAI) models that bridge the usability gap of AI by providing a natural lang…
Aperiodic clustered and periodic hexagonal vegetation spot arrays explained by inhomogeneous environments and climate trends in arid ecosystems
D. Pinto-Ramos, M. G. Clerc, A. Makhoute +1
Due to climate change, overgrazing, and deforestation, arid ecosystems are vulnerable to desertification and land degradation. As aridity increases, vegetation cover loses spatial…
A study on information disorders on social networks during the Chilean social outbreak and COVID-19 pandemic
Marcelo Mendoza, Sebastián Valenzuela, Enrique Núñez-Mussa +7
Information disorders on social media can have a significant impact on citizens' participation in democratic processes. To better understand the spread of false and inaccurate info…
Predicting affinity ties in a surname network
Marcelo Mendoza, Naim Bro
From administrative registers of last names in Santiago, Chile, we create a surname affinity network that encodes socioeconomic data. This network is a multi-relational graph with…
Surname affinity in Santiago, Chile: A network-based approach that uncovers urban segregation
Naim Bro, Marcelo Mendoza
Based on a geocoded registry of more than four million residents of Santiago, Chile, we build two surname-based networks that reveal the city's population structure. The first netw…
Calibration Strategy of the JUNO-TAO Experiment
Hangkun Xu, Angel Abusleme, Nikolay V. Anfimov +67
The Taishan Antineutrino Observatory (JUNO-TAO, or TAO) is a satellite detector for the Jiangmen Underground Neutrino Observatory (JUNO). Located near the Taishan reactor, TAO inde…
Probabilistic Automata of Bounded Ambiguity
Nathanaël Fijalkow, Cristian Riveros, James Worrell
Probabilistic automata are an extension of nondeterministic finite automata in which transitions are annotated with probabilities. Despite its simplicity, this model is very expres…
Status and initial physics performance studies of the MPD experiment at NICA
MPD Collaboration, V. Abgaryan, R. Acevedo Kado +470
The Nuclotron-base Ion Collider fAcility (NICA) is under construction at the Joint Institute for Nuclear Research (JINR), with commissioning of the facility expected in late 2022.…
AHMoSe: A Knowledge-Based Visual Support System for Selecting Regression Machine Learning Models
Diego Rojo, Nyi Nyi Htun, Denis Parra +2
Decision support systems have become increasingly popular in the domain of agriculture. With the development of automated machine learning, agricultural experts are now able to tra…
Continuous Positional Payoffs
Alexander Kozachinskiy
What payoffs are positionally determined for deterministic two-player antagonistic games on finite directed graphs? In this paper we study this question for payoffs that are contin…
Transmission Estimation at the Cramér-Rao Bound for Squeezed States of Light in the Presence of Loss and Imperfect Detection
Timothy S. Woodworth, Kam Wai Clifford Chan, Carla Hermann-Avigliano +1
Enhancing the precision of a measurement requires maximizing the information that can be gained about the quantity of interest from probing a system. For optical based measurements…
Deterministic Generation of Large Fock States
M. Uria, P. Solano, C. Hermann-Avigliano
We present a protocol to deterministically prepare the electromagnetic field in a large photon number state. The field starts in a coherent state and, through resonant interaction…
On the Reproducibility of Experiments of Indexing Repetitive Document Collections
Antonio Fariña, Miguel A. Martínez-Prieto, Francisco Claude +4
This work introduces a companion reproducible paper with the aim of allowing the exact replication of the methods, experiments, and results discussed in a previous work [5]. In tha…
Assessing the best edit in perturbation-based iterative refinement algorithms to compute the median string
P. Mirabal, J. Abreu, D. Seco
Strings are a natural representation of biological data such as DNA, RNA and protein sequences. The problem of finding a string that summarizes a set of sequences has direct applic…
New structures to solve aggregated queries for trips over public transportation networks
Nieves R. Brisaboa, Antonio Fariña, Daniil Galaktionov +2
Representing the trajectories of mobile objects is a hot topic from the widespread use of smartphones and other GPS devices. However, few works have focused on representing trips o…
Faster Dynamic Compressed d-ary Relations
Diego Arroyuelo, Guillermo de Bernardo, Travis Gagie +1
The -tree is a successful compact representation of binary relations that exhibit sparseness and/or clustering properties. It can be extended to dimensions, where it is ca…
