Noise effects in two different biological systems
The European Physical Journal B - Tập 69 - Trang 133-146 - 2009
We investigate the role of the colored noise in two
biological systems: (i) adults of Nezara viridula (L.)
(Heteroptera: Pentatomidae), and (ii) polymer translocation. In the
first system we analyze, by directionality tests, the response of
N. viridula individuals to subthreshold signals plus noise
in their mating behaviour. The percentage of insects that react to
the subthreshold signal shows a n...... hiện toàn bộ
Comment on “On the controversy around Daganzo’s requiem for and Aw-Rascle’s resurrection of second-order traffic flow models" by D. Helbing and A.F. Johansson
The European Physical Journal B - Tập 69 - Trang 563-568 - 2009
There has been a debate in the transportation research
community over the validity of a class of traffic flow models.
These models have the peculiar property that one of its characteristic speeds
is faster than that of vehicular traffic. This note attempts to
provide an overview of the diverging views on how to interpret this property, and
specific comments on the interpretation of Helbing an...... hiện toàn bộ
Néel ordered versus quantum disordered behavior in doped spin-Peierls and Haldane gap systems
The European Physical Journal B - Tập 18 - Trang 263-273 - 2000
I consider a theoretical description of recent experiments on doping the spin-Peierls compound CuGeO3 and the Haldane gap compounds PbNi2V2O8 and Y2BaNiO5. The effective theory is the one of randomly distributed spin-1/2 moments interacting with an exchange decaying exponentially with distance. The model has two phases in the (doping, interchain coupling) plane: (i) a Néel ordered phase at small d...... hiện toàn bộ
Dynamics of matter-wave solitons in Bose-Einstein condensates with time-dependent scattering length and complex potentials
The European Physical Journal B - Tập 89 - Trang 1-12 - 2016
We investigate the dynamics of matter-wave solitons in the one-dimensional (1-D)
Gross-Pitaevskii (GP) equation describing Bose-Einstein condensates (BECs) with
time-dependent scattering length in varying trapping potentials with feeding/loss term. By
performing a modified lens-type transformation, we reduce the GP equation into a classical
nonlinear Schrödinger (NLS) equation with distributed coe...... hiện toàn bộ
A neutron reflectometry study of polystyrene network interfaces
The European Physical Journal B - Tập 3 - Trang 83-96 - 1998
We have used neutron reflectometry to measure interfacial widths between two polystyrene films, where either one or both films are crosslinked. The observed interfacial width between two networks is larger than the size expected for “dangling ends”, which suggests motion of heterogeneous regions of the networks. In the case when one of the networks is replaced by a linear polymer, the interfacial ...... hiện toàn bộ
Model of mobile agents for sexual interactions networks
The European Physical Journal B - Tập 49 - Trang 371-376 - 2006
We present a novel model to simulate real social networks of complex
interactions, based in a system of colliding particles
(agents).
The network is build by keeping track of the collisions and evolves in
time with correlations which emerge due to the mobility of the agents.
Therefore, statistical features are a consequence only of local
collisions among its individual agents.
Agent dynamics is...... hiện toàn bộ
Electromagnetic fields produced by sources on a spherical wavefront
The European Physical Journal B - Tập 18 - Trang 85-93 - 2000
Transient solutions of the inhomogeneous Maxwell equations are obtained. The specific current source belongs to the spherical surface expanding with the velocity of light. Representations of the electromagnetic field components in the spherical coordinates in terms of the Fourier series are found. The obtained solutions are correct near the wavefront. The general expressions are applied to a descr...... hiện toàn bộ
Eigenfunction structure and scaling of two interacting particles in the one-dimensional Anderson model
The European Physical Journal B - Tập 89 - Trang 1-26 - 2016
The localization properties of eigenfunctions for two interacting particles in the
one-dimensional Anderson model are studied for system sizes up to N = 5000 sites
corresponding to a Hilbert space of dimension ≈107 using the Green function Arnoldi method. The
eigenfunction structure is illustrated in position, momentum and energy representation,
the latter corresponding to an expansion in non-int...... hiện toàn bộ
