Generation of probabilistic synthetic data for serious games: a case study on cyberbullying
Pérez Sánchez, Jaime; Castro Ponce, Mario; Awad, Edmond; López López, Gregorio (2024-02-28)Synthetic data generation has been a growing area of research in recent years. However, its potential applications in serious games have yet to be thoroughly explored. Advances in this field could anticipate data modeling ... -
Generic equations for pattern formation in evolving interfaces
Castro Ponce, Mario; Muñoz García, J.; Cuerno Rejado, Rodolfo; Hernández, M.D.G.; Vázquez Burgos, Luís Fernando (2007-04-01)We present a general formalism which allows us to derive the evolution equations describing one-dimensional (1D) and isotropic 2D interface-like systems, that is based on symmetries, conservation laws, multiple scale ... -

Hidden structure in the randomness of the prime number sequence?
Ares, Saúl; Castro Ponce, Mario (2006-02-01)We report a rigorous theory to show the origin of the unexpected periodic behavior seen in the consecutive differences between prime numbers. We also check numerically our findings to ensure that they hold for finite ... -
Hydrodynamic approach to surface pattern formation by ion beams
Castro Ponce, Mario; Cuerno Rejado, Rodolfo (2012-02-15)On the proper timescale, amorphous solids can flow. Solid flow can be observed macroscopically in glaciers or lead pipes, but it can also be artificially enhanced by creating defects. Ion Beam Sputtering (IBS) is a technique ... -
IDSAI: A Distributed System for Intrusion Detection Based on Intelligent Agents
Sanz Bobi, Miguel Ángel; Castro Ponce, Mario; Santos Ferreras, Javier (IARIA (International Academy, Research and Industry Association) (Barcelona, España), 2010-05-09)This paper describes an intelligent system for automatic detection of intrusions in computer networks. Its architecture is based on a multi-agent system in which several types of agents cooperate together to perform a fast ... -
IL7 receptor signaling in T cells: A mathematical modeling perspective
Park, Jung-Hyun; Waickman, Adam T; Reynolds, Joseph; Castro Ponce, Mario; Molina París, Carmen (2019-10-01)Interleukin-7 (IL7) plays a nonredundant role in T cell survival and homeostasis, which is illustrated in the severe T cell lymphopenia of IL7-deficient mice, or demonstrated in animals or humans that lack expression of ... -
Impact of polling on Bluetooth piconet performance
Contreras Bárcena, David; Castro Ponce, Mario (2011-09-01)Bluetooth has become a ubiquitous technology present in almost every electronic device. A question often asked by manufacturers and final users is whether it can be used for uses other than the ones for which it was designed; ... -
Independence of interrupted coarsening on initial system order: ion-beam nanopatterning of amorphous versus crystalline silicon targets
Muñoz García, J.; Gago Fernández, Raúl; Cuerno Rejado, Rodolfo; Sánchez García, José Ángel; Redondo Cubero, Andrés; Castro Ponce, Mario; Vázquez Burgos, Luís Fernando (2012-09-19)Interrupted coarsening (IC) has recently been identified as an important feature for the dynamics of the typical length-scale in pattern-forming systems on surfaces. In practice, it can be beneficial to improve pattern ... -
Interplay between morphology and surface transport in nanopatterns produced by ion-beam sputtering
Cuerno Rejado, Rodolfo; Muñoz García, J.; Castro Ponce, Mario; Gago Fernández, Raúl; Vázquez Burgos, Luís Fernando (2007-12-01)A "hydrodynamic" model has been proposed to describe nanopattern formation and dynamics on amorphous surfaces eroded by ion-beam sputtering (IBS), that relates to descriptions of pattern formation in macroscopic systems ... -

Kinetic roughening in a realistic model of non-conserved interface growth
Nicoli, Matteo; Castro Ponce, Mario; Cuerno Rejado, Rodolfo (2009-02-01)We provide a quantitative picture of non-conserved interface growth from a diffusive field, placing special emphasis on two main issues, the range of validity of the effective small slopes (interfacial) theories and the ... -
Leveraging national forestry data repositories to advocate wildfire modeling towards simulation-driven risk assessment
Gómez González, Juan Luis; Cantizano González, Alexis; Caro Carretero, Raquel; Castro Ponce, Mario (2024-01-01)Modeling wildfire dynamics is complex and challenging due to the multiple scales involved in fire propagation, from physical–chemical processes to the interaction with topography and meteorological conditions. To provide ... -
