(AMER PHYSICAL SOC, 2008-05)We study theoretically a family of localized states which asymptotically connect a uniform oscillatory state in the magnetization of an easy-plane ferromagnetic spin chain when an oscillator magnetic field is applied ...
-
(AMERICAN PHYSICAL SOC, 2006-06)We present a unifying description close to a spatial bifurcation of localized states, appearing as large amplitude peaks nucleating over a pattern of lower amplitude. Localized states are pinned over a lattice spontaneously ...
-
(Springer, 2017)Driven damped coupled oscillators exhibit complex spatiotemporal dynamics. An archetype model is the driven damped sine-Gordon equation, which can describe several physical systems such as coupled pendula, extended Josephson ...
-
(2005)We study numerically a prototype equation which arises generically as an envelope equa- tion for a weakly inverted bifurcation associated to traveling waves: The complex quintic Ginzburg{Landau equation. We show six di ...
-
(American Physical Society, 2015)We investigate the formation of localized structures with varying widths in one- and two-dimensional systems. The mechanism of stabilization is attributed to strongly nonlocal coupling mediated by a Lorentzian type ...
-
(EPL ASSOCIATION, EUROPEAN PHYSICAL SOCIETY, 2012-02)The pattern formation in a magnetic wire forced by a transversal uniform and oscillatory magnetic field is studied. This system is described in the continuous framework by the Landau-Lifshitz-Gilbert equation. We find ...
-
(2016)Location privacy is a concern in mobile networks monitoring systems. We propose a model using homomorphic encryption, where researchers can compute aggregations, learning nothing more about users' location than the result ...
-
(Nature Research, 2021)As the novel coronavirus (COVID-19) pandemic spread across the world over the past year, many countries imposed lockdowns in the form of stay at home requirements on their citizens to mitigate its spread. We analyze mobility ...
-
(Oxford University Press, 2016)We test the assumption of hydrostatic equilibrium in an X-ray luminosity selected sample of 50 galaxy clusters at 0.15 < z < 0.3 from the Local Cluster Substructure Survey (LoCuSS). Our weak-lensing measurements of M500 ...
-
(Oxford University Press, 2018-07)Galaxy clusters are expected to form hierarchically in a Lambda cold dark matter (Lambda CDM) universe, growing primarily through mergers with lower mass clusters and the continual accretion of group-mass haloes. Galaxy ...
-
(IOP Publishing, 2015)We present a study of the spatial distribution and kinematics of star-forming galaxies in 30 massive clusters at 0.15 < z < 0.30, combining wide-field Spitzer 24 mu m and GALEX near-ultraviolet imaging with highly complete ...
-
(Springer, 2013)We prove that under n1/3 scaling, the limiting distribution as n → ∞of the free energy of Seppäläinen’s log-Gamma discrete directed polymer is GUE Tracy- Widom. The main technical innovation we provide is a general ...
-
(Elsevier, 2013)The identification of seismic records in seismically active mines is examined by considering logistic regression and neural network classification techniques. An efficient methodology is presented for applying these ...
-
(IOP, 2020)Using the Atacama Large Millimeter/submillimeter Array, we observed the young Herbig star HD 100546, host to a prominent disk with a deep, wide gap in the dust. The high-resolution 1.3 mm continuum observation reveals fine ...

(Research Publishing, Singapore, 2020)
-
(E D P SCIENCES, 7, AVE DU HOGGAR, PARC D ACTIVITES COURTABOEUF, 2004)We present the kinematical data obtained for a sample of active (Seyfert) and non active isolated spiral galaxies, based on long slit spectra along several position angles in the Hα line region and, in some cases, in the ...
-
(Springer, 2017)A fluid queuing network constitutes one of the simplest mod-els in which to study flow dynamics over a network. In this model wehave a single source-sink pair and each link has a per-time-unit capac-ity and a transit time. ...
-
(2016)We study the long-time behavior of variants of the telegraph process with position-dependent jump rates, which result in a monotone gradient-like drift towards the origin. We compute their invariant laws and obtain, via ...
-
(2010)The Doppler wobble induced by the extra-solar planet HD 134987b was first detected by data from the Keck Telescope nearly a decade ago, and was subsequently confirmed by data from the Anglo-Australian Telescope (AAT). ...
-
(Mosby Inc., 2019)Introduction: Laparoscopic Nissen fundoplication is the preferred operative treatment for patients with gastroesophageal reflux disease. The most recent published results only refer to clinical evaluations and few discuss ...
