Learning to Recognize 3D Human Action from A New Skeleton-based Representation Using Deep Convolutional Neural Networks
Huy-Hieu Pham, Louahdi Khoudour, Alain Crouzil +2
Recognizing human actions in untrimmed videos is an important challenging task. An effective 3D motion representation and a powerful learning model are two key factors influencing…
Large-scale analysis of user exposure to online advertising in Facebook
Aritz Arrate, José González Cabañas, Ángel Cuevas +2
Online advertising is the major source of income for a large portion of Internet Services. There exists a body of literature aiming at optimizing ads engagement, understanding the…
Valley Hall phases in Kagome lattices
Natalia Lera, Daniel Torrent, Pablo San-Jose +2
We report the finding of the analogous valley Hall effect in phononic systems arising from mirror symmetry breaking, in addition to spatial inversion symmetry breaking. We study to…
Ultrathin acoustic parity-time symmetric metasurface cloak
Hao-Xiang Li, Maria Rosendo-Lopez, Yi-Fan Zhu +5
Invisibility or unhearability cloaks have been made possible by using metamaterials making light or sound flow around obstacle without the trace of reflections or shadows. Metamate…
Symmetry protected phases in inhomogeneous spin chains
Nadir Samos Sáenz de Buruaga, Silvia N. Santalla, Javier Rodríguez-Laguna +1
It has been shown recently that inhomogenous spin chains can exhibit exotic phenomena such as the breaking of the area law of the entanglement entropy. An example is given by the r…
Gas bubble evolution on microstructured silicon substrates
Peter van der Linde, Pablo Peñas-López, Álvaro Moreno Soto +4
The formation, growth and detachment of gas bubbles on electrodes are omnipresent in electrolysis and other gas-producing chemical processes. To better understand their role in the…
Crossover between parabolic and hyperbolic scaling, oscillatory modes and resonances near flocking
L. L. Bonilla, C. Trenado
A stability and bifurcation analysis of a kinetic equation indicates that the flocking bifurcation of the two-dimensional Vicsek model exhibits an interplay between parabolic and h…
Comment on "Revision of Bubble Bursting: Universal Scaling Laws of Top Jet Drop Size and Speed"
José Manuel Gordillo, Javier Rodríguez-Rodríguez

Variations on the Boman covering lemma
J. M. Aldaz
We explore some variants of the Boman covering lemma, and their relationship to the boundedness properties of the maximal operator. Let and let be its conjugat…
Data-Driven Interaction Review of an Ed-Tech Application
Alejandro Baldominos, David Quintana
Smile and Learn is an Ed-Tech company that runs a smart library with more that 100 applications, games and interactive stories, aimed at children aged two to 10 and their families.…
Interactive Secure Function Computation
Deepesh Data, Gowtham R. Kurri, Jithin Ravi +1
We consider interactive computation of randomized functions between two users with the following privacy requirement: the interaction should not reveal to either user any extra inf…
A note on abscissas of Dirichlet series
Andreas Defant, Antonio Pérez, Pablo Sevilla-Peris
We present an abstract approach to the abscissas of convergence of vector-valued Dirichlet series. As a consequence we deduce that the abscissas for Hardy spaces of Dirichlet serie…
Image-based model parameter optimization using Model-Assisted Generative Adversarial Networks
Saúl Alonso-Monsalve, Leigh H. Whitehead
We propose and demonstrate the use of a model-assisted generative adversarial network (GAN) to produce fake images that accurately match true images through the variation of the pa…
High-order stroboscopic averaging methods for highly oscillatory delay problems
M. P. Calvo, J. M. Sanz-Serna, Beibei Zhu
We introduce and analyze a family of heterogeneous multiscale methods for the numerical integration of highly oscillatory systems of delay differential equations with constant dela…
The role of slip transfer at grain boundaries in the propagation of microstructurally short fatigue cracks in Ni-based superalloys
M. Jiménez, W. Ludwig, D. Gonzalez +1
Crack initiation and propagation under high-cycle fatigue conditions have been investigated for a polycrystalline Ni-based superalloy by in-situ synchrotron assisted diffraction an…
Lagrangian study of the final warming in the southern stratosphere during 2002: Part II. 3D structure
Jezabel Curbelo, Carlos R. Mechoso, Ana M. Mancho +1
This two-part paper aims to provide a Lagrangian perspective of the final southern warming in spring of 2002, during which the stratospheric polar vortex (SPV) experienced a unique…
Lagrangian study of the final warming in the southern stratosphere during 2002: Part I. The Vortex Splitting at Upper Levels
Jezabel Curbelo, Carlos R. Mechoso, Ana M. Mancho +1
The present two-part paper provides a Lagrangian perspective of the final southern warming in 2002, during which the stratospheric polar vortex (SPV) experienced a unique splitting…
Stratified Manifold of Quantum States, actions of the complex special linear group
Dariusz Chruscinski, Florio M. Ciaglia, Alberto Ibort +2
We review the geometry of the space of quantum states of a finite-level quantum system with Hilbert space from a group-theoretical point of…
The MalSource Dataset: Quantifying Complexity and Code Reuse in Malware Development
Alejandro Calleja, Juan Tapiador, Juan Caballero
During the last decades, the problem of malicious and unwanted software (malware) has surged in numbers and sophistication. Malware plays a key role in most of today's cyber attack…
The case for shifting the Renyi Entropy
Francisco José Valverde-Albacete, Carmen Peláez-Moreno
We introduce a variant of the Rényi entropy definition that aligns it with the well-known Hölder mean: in the new formulation, the r-th order Rényi Entropy is the logarithm of the…
Contact Hamiltonian Systems
Manuel Lainz Valcázar, Manuel de León
In this paper we study Hamiltonian systems on contact manifolds, which is an appropriate scenario to discuss dissipative systems. We prove a coisotropic reduction theorem similar t…
