  • Shortest coordinated motions for square robots 

    Esteban, Guillermo; Halperin, Dan; Silveira, Rodrigo Ignacio (2025-05-08)
    Article
    Open Access
    We study the problem of determining minimum-length coordinated motions for two axis-aligned square robots translating in an obstacle-free plane: Given feasible start and goal configurations (feasible in the sense that the ...
  • DEFENDIFY: defense amplified with transfer learning for obfuscated malware framework 

    Castillo Camargo, Rodrigo; Murcia Nieto, Juan; Rojas, Nicolás; Díaz López, Daniel; Alférez Baquero, Edwin Santiago; Perales Gómez, Angel Luis; Nespoli, Pantaleone; Gómez Mármol, Félix; Karabiyik, Umit (Springer, 2025-12-01)
    Article
    Open Access
    The existence of malicious software (malware) represents a potential threat to users who connect to a large set of services provided by multiple providers. Such malware is capable of stealing, spying on, encrypting data ...
  • Real-time worldwide monitoring of ionospheric scintillation using geodetic detrending 

    Yin, Yu; González Casado, Guillermo; Juan Zornoza, José Miguel; Timoté Bejarano, Cristhian Camilo; García Mateos, Jorge; Orús Pérez, Raul; Aragón Ángel, María Ángeles; Rovira Garcia, Adrià (Institute of Electrical and Electronics Engineers (IEEE), 2025-01-10)
    Article
    Open Access
    A real-time (RT) ionospheric scintillation monitoring tool has been developed based on observations from geodetic receivers in Global Navigation Satellite System (GNSS) networks. It extends the application of the Geodetic ...

  • Strain virtual sensor for offshore wind turbine jacket supports: a time series transformer approach validated with Alpha Ventus wind farm data 

    Encalada-Dávila, Ángel; Vidal Seguí, Yolanda; Tutivén Gálvez, Christian (2025-05)
    Article
    Open Access
    Monitoring the structural health of offshore wind turbines in harsh marine environments presents significant challenges due to physical sensor limitations, such as susceptibility to high salinity, strong underwater currents, ...
  • Oscillatory motions, parabolic orbits and collision orbits in the planar circular restricted three-body problem 

    Lamas Rodríguez, José; Guàrdia Munarriz, Marcel; Martínez-Seara Alonso, M. Teresa (Springer, 2025-04-10)
    Article
    Restricted access - publisher's policy
    In this paper we consider the planar circular restricted three body problem (PCRTBP), which models the motion of a massless body under the attraction of other two bodies, the primaries, which describe circular orbits around ...
  • Predictive factors of chronic venous disease: a clinical study 

    Perarnau Pauner, Mònica; Rossell Garriga, Josep Maria (2025-05-13)
    Article
    Open Access
    Objective: The aim is to analyse the combination of factors that may be related to chronic venous disease in order to develop future prevention policies. Material and Methods: The study is based on a medical examination ...
  • Global bifurcation in a virus, defective genomes, satellite RNAs tripartite system: breakdown of a coexistence quasi-neutral curve 

    Llopis Almela, Oriol; Lázaro Ochoa, José Tomás; Elena, Santiago; Sardanyes Cayuela, Josep (Elsevier, 2025-03)
    Article
    Restricted access - publisher's policy
    The dynamics of wild-type (wt) RNA viruses and their defective viral genomes (DVGs) have been extensively studied both experimentally and theoretically. This research has paid special attention to the interference effects ...
  • Polynomial normal forms for ODEs near a center-saddle equilibrium point 

    Delshams Valdés, Amadeu; Zgliczynski, Piotr (2025-08-15)
    Article
    Open Access
    In this work we consider a saddle-center equilibrium for general vector fields as well as Hamiltonian systems, and we transform it locally into a polynomial normal form in the saddle variables by a change of coordinates. ...

  • Polynomial factorization over Henselian fields 

    Alberich Carramiñana, Maria; Guàrdia Rubies, Jordi; Nart Vinyals, Enric; Poteaux, Adrien; Roé Vallvé, Joaquim; Weimann, Martin (Springer, 2024-02-21)
    Article
    Open Access
    We present an algorithm that, given an irreducible polynomial g over a general valued field (K, v), finds the factorization of g over the Henselianization of K under certain conditions. The analysis leading to the algorithm ...
  • An approach to the optimization of the progressive freeze concentration of sucrose solutions in an agitated vessel 

    Moussaoui, Chaimae; Blanco Abellán, Mónica; De Bona, Isabella; Raventós Santamaria, Mercè; Hernández Yáñez, Eduard (2018-08-24)
    Article
    Open Access
    The freeze concentration of liquid foods is a technique that consists of separating the water from the liquid fluid food through freezing. It is an emerging technology that uses low temperatures in the process offering the ...
