Indirect influence on network diffusion Open
Models of network diffusion typically rely on the Laplacian matrix, capturing interactions via direct connections. Beyond direct interactions, information in many systems can also flow via indirect pathways, where influence typically dimin…
Fully and semi-implicit robust space–time DG methods for the incompressible Navier–Stokes equations Open
We carry out a stability and convergence analysis of a fully discrete scheme for the time-dependent Navier–Stokes equations resulting from combining an [Formula: see text]-conforming discontinuous Galerkin spatial discretization, and a dis…

ZOGRASCOPE: A New Benchmark for Semantic Parsing over Property Graphs Open
In recent years, the need for natural language interfaces to knowledge graphs has become increasingly important since they enable easy and efficient access to the information contained in them. In particular, property graphs (PGs) have see…
A variational approach to the analysis of the continuous space-time FEM for the wave equation Open
We present a stability and convergence analysis of the space-time continuous finite element method for the Hamiltonian formulation of the wave equation. More precisely, we prove a continuous dependence of the discrete solution on the data …
Machine learning mathematical models for incidence estimation during pandemics Open
Accurate estimates of the incidence of infectious diseases are key for the control of epidemics. However, healthcare systems are often unable to test the population exhaustively, especially when asymptomatic and paucisymptomatic cases are …
SUPG-stabilized time-DG finite and virtual elements for the time-dependent advection-diffusion equation Open
We carry out a stability and convergence analysis for the fully discrete scheme obtained by combining a finite or virtual element spatial discretization with the upwind-discontinuous Galerkin time-stepping applied to the time-dependent adv…
Probabilistic Discrete‐Time Models for Spreading Processes in Complex Networks: A Review Open
Research into network dynamics of spreading processes typically employs both discrete and continuous time methodologies. Although each approach offers distinct insights, integrating them can be challenging, particularly when maintaining co…
Structural prediction of super-diffusion in multiplex networks Open
Diffusion dynamics in multiplex networks can model a diverse number of real-world processes. In some specific configurations of these systems, the super-diffusion phenomenon arises, in which the diffusion is faster in the multiplex network…
Rebound in epidemic control: How misaligned vaccination timing amplifies infection peaks Open
In this study, we explore the dynamic interplay between the timing of vaccination campaigns and the trajectory of disease spread in a population. Through comprehensive data analysis and modeling, we have uncovered a counter-intuitive pheno…

Analysis of a Large Severe Acute Respiratory Syndrome Coronavirus 2 (Alpha) Outbreak in a Catalan Prison Using Conventional and Genomic Epidemiology Open
Enforcing strict protocols that prevent transmission of airborne infections in prisons is challenging. We examine a large severe acute respiratory syndrome coronavirus 2 outbreak in a Catalan penitentiary center in February–April 2021, pri…
mdendro: An R package for extended agglomerative hierarchical clustering Open
"mdendro" is an R package that provides a comprehensive collection of linkage methods for agglomerative hierarchical clustering on a matrix of proximity data (distances or similarities), returning a multifurcated dendrogram or multidendrog…
On the number of stable solutions in the Kuramoto model Open
We consider a system of n coupled oscillators described by the Kuramoto model with the dynamics given by θ˙=ω+Kf(θ). In this system, an equilibrium solution θ∗ is considered stable when ω+Kf(θ∗)=0, and the Jacobian matrix Df(θ∗) has a simp…
Pattern formation and bifurcation analysis of delay induced fractional-order epidemic spreading on networks Open
The spontaneous emergence of ordered structures, known as Turing patterns, in complex networks is a phenomenon that holds potential applications across diverse scientific fields, including biology, chemistry, and physics. Here, we present …

A triadic approximation reveals the role of interaction overlap on the spread of complex contagions on higher-order networks Open
Contagion processes relying on the exposure to multiple sources are prevalent in social systems, and are effectively represented by hypergraphs. In this Letter, we derive a mean-field model that goes beyond node- and pair-based approximati…
A space-time DG method for the Schrödinger equation with variable potential Open
We present a space-time ultra-weak discontinuous Galerkin discretization of the linear Schrödinger equation with variable potential. The proposed method is well-posed and quasi-optimal in mesh-dependent norms for very general discrete spac…
Joint Analysis of the Epidemic Evolution and Human Mobility During the First Wave of COVID-19 in Spain: Retrospective Study Open
Background The initial wave of the COVID-19 pandemic placed a tremendous strain on health care systems worldwide. To mitigate the spread of the virus, many countries implemented stringent nonpharmaceutical interventions (NPIs), which signi…
A Low-Cost Wearable Autonomous System for the Protection of Bicycle Users Open
A bicycle is a form of transport that not only positively impacts the health of users, and the general population by reducing pollution levels but also constitutes an accessible and affordable means of transport for developing societies. H…
Spreading dynamics in networks under context-dependent behavior Open
In some systems, the behavior of the constituent units can create a `context' that modifies the direct interactions among them. This mechanism of indirect modification inspired us to develop a minimal model of context-dependent spreading. …
A link model approach to identify congestion hotspots Open
Congestion emerges when high demand peaks put transportation systems under stress. Understanding the interplay between the spatial organization of demand, the route choices of citizens and the underlying infrastructures is thus crucial to …
