(American Physical Society, 2018)Spatially forced systems can exhibit coexistence and a rich interface dynamics between manipulable states. We show here how the propagation speed of a front into an unstable state can be modified through periodic space ...
-
(American Institute of Physics, 2020)Homogeneously driven dynamical systems exhibit multistability. Depending on the initial conditions, fronts present a rich dynamical behavior between equilibria. Qualitatively, this phenomenology is persistent under spatially ...
-
(AMERICAN PHYSICAL SOC, 2006-07)The effect of noise in a motionless front between a periodic spatial state and an homogeneous one is studied. Numerical simulations show that noise induces front propagation. From the subcritical Swift-Hohenberg equation ...
-
(OSA - The Optical Society, 2019)Driven optical systems can exhibit coexistence of equilibrium states. Traveling waves or fronts between different states present complex spatiotemporal dynamics. We investigate the mechanisms that govern the front spread. ...
-
(Frontiers Media S.A., 2019)In humans and non-humans primates, extensive evidence supports the existence of subcortico-cortical circuits for cognition and behavior. Lesions studies are critical to understand the clinical significance of these ...
-
(ELSEVIER, 2004-12-01)We show that in a liquid-crystal-light-valve with optical feedback the Freedericksz transition displays a subcritical character. Experimentally, we determine the extension of the bistable region and we study the propagation ...
-
(MDPI, 2018)A fully adaptive particle filtering algorithm is proposed in this paper which is capable of updating both state process models and measurement models separately and simultaneously. The approach is a significant step toward ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2005-12)A fully coupled "online" Weather Research and Forecasting/Chemistry (WRF/Chem) model has been developed. The air quality component of the model is fully consistent with the meteorological component; both components use the ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2011-06)Metric access methods based on hyperplane partitioning have the advantage, compared to the ball partitioning-based ones, that regions do not overlap. The price is less flexibility for controlling the tree shape, especially ...
-
(ACM, 2014)We propose new succinct representations of ordinal trees and match various space/time lower bounds. It is known that any n-node static tree can be represented in 2n + o(n) bits so that a number of operations on the tree ...
-
(Assoc Computing Machinery, USA, 2020)Indexing highly repetitive texts-such as genomic databases, software repositories and versioned text collections-has become an important problem since the turn of the millennium. A relevant compressibility measure for ...
-
(Springer, 2016)The present work is focused on the numerical approximation of the shallow water equations. When studying this problem, one faces at least two important issues, namely the ability of the scheme to preserve the positiveness ...
-
(2007)By examining the structure in momentum and coordinate space of a two-body interaction spherically symmetric in its local coordinate, we demonstrate that it can be disentangled into two distinctive contributions. One of ...
-
(BLACKWELL, 2006-09-21)In this paper, we present the first BV I CCD photometry of six overlooked old open clusters (Berkeley 44, NGC 6827, Berkeley 52, Berkeley 56, Skiff 1 and Berkeley 5) and derive estimates of their fundamental parameters by ...
-
(2004-12-20)We measured the stellar velocity dispersions of 15 active galactic nucleus (AGN) host galaxies at redshifts as high as 0.34. Combining these with published velocity dispersion measurements from the literature, we study the ...
-
(Royal Soc, 2015)In this paper, both singular and hypersingular fundamental solutions of plane Cosserat elasticity are derived and given in a ready-to-use form. The hypersingular fundamental solutions allow to formulate the analogue of ...
-
(Elsevier, 2011)In this article we study basic properties for a class of nonlinear integral operators related to their fundamental solutions. Our goal is to establish Liouville type theorems: non-existence theorems for positive entire ...
-
(BLACKWELL SCIENCE LTD, 1999-10-11)We present the spectra and redshifts of 62 quasars, from observations made with the Cerro Tololo Inter-American Observatory (CTIO) 4-m Blanco Telescope. These quasars form part of a total sample of 118 (with 56 having been ...
-
(Elsevier, 2014)Face recognition is one of the most extensively studied topics in image analysis because of its wide range of possible applications such as in surveillance, access control, content-based video search, human–computer ...
-
(MDPI, 2020)The freezing level in the free troposphere often intercepts the terrain of the world's major mountain ranges, creating a rain-snow limit. In this work, we use the free tropospheric height of the 0 degrees C isotherm (H0) ...
