(Elsevier, 2013)We explore the nontrivial behavior of a particular city traffic model due to its minimalistic representation of basic city traffic dynamics. The chaotic behavior is studied through the supertrack functions, an approach ...

Nonadditive effects of flower damage and hummingbird pollination on the fecundity of Mimulus luteus (SPRINGER, 2006-10)Flower herbivory and pollination have been described as interactive processes that influence each other in their effects on plant reproductive success. Few studies, however, have so far examined their joint effects in ...
-
(2007)The effect of mutualists (i.e. pollinators) and antagonists (i.e. herbivores) can have non-additive effects on plant fitness. This is often interpreted as evidence for correlated evolution on a suite of traits leading to ...
-
(Wiley, 2019)Complexity is a concept that is being considered in chemistry as it has shown potential to revealinteresting phenomena. Thus, it is possible to study chemical phenomena in a new approachcalled systems chemistry. The systems ...

(Springer, 2021)It is proved that accelerating nondiffracting gravitational Airy wave-packets are solutions of linearized gravity. It is also showed that Airy functions are exact solutions to Einstein equations for non-accelerating ...
-
(EUROPEAN GEOSCIENCES UNION, 2006)The nonextensive statistics formalism proposed by Tsallis has found many applications in systems with memory effects, long range spatial correlations, and in general whenever the phase space has fractal or multi-fractal ...
-
(Wiley & Sons, 2015)The excitons in the orthorhombic phase of the perovskite CH3NH3PbI3 are studied using the effective mass approximation. The electron-hole interaction is screened by a distance-dependent dielectric function, as described ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2006-10)Polycrystalline bismuth sample was compressed in a diamond anvil cell and X-ray diffraction patterns from the body centered cubic phase of bismuth (bcc-Bi) recorded in the pressure range 12-222 GPa. The analysis of diffraction ...
-
(Bentham open, 2008-11-26)Finite amplitude Alfvén-cyclotron waves are believed to play an important role in coronal heating and nonthermal properties of velocity distribution functions. These effects are thought to be due to parametrically ...
-
(Elsevier, 2014)Starting with a boundary triangulation an algorithm automatically generates graded densities of triangular elements inside arbitrary polygonal domains. Interior nodes generated inside acute triangles receive spacing ...
-
(2003)We examine the bound state(s) associated with a single cubic nonlinear impurity, in a one-dimensional tight-binding lattice, where hopping to first- and second-nearest neighbors is allowed. The model is solved in a closed ...
-
(1999)We use the Green’s-function formalism for an exact, numerical calculation of the stationary states of an electron propagating in a square lattice in the presence of a single, Holstein-type, impurity of arbitrary nonlinearity ...
-
(2007)It is shown that in a plasma composed by electrons, a proton core, and a proton beam propagating along an external magnetic field, finite amplitude left-hand polarized waves propagating backward relative to the beam direction ...
-
(2009)We analyze the existence and stability of nonlinear modes localized at phase-slip waveguide channels and their intersections in two-dimensional photonic lattices with rectangular symmetry. While in linear lattices only one ...
-
(OPTICAL SOC AMER, 2008-05-01)We study light localization at a phase-slip defect created by two semi-infinite mismatched identical arrays of coupled optical waveguides. We demonstrate that the nonlinear defect modes possess the specific properties of ...
-
(2011)Modulational instability and discrete matter wave solitons in dipolar BECs, loaded into a deep optical lattice, are investigated analytically and numerically. The process of modulational instability of nonlinear plane ...

Nonlinear localized modes in dipolar Bose-Einstein condensates in two-dimensional optical lattices (Elsevier B.V., 2016)© 2016 Elsevier B.V. We analyze the existence and properties of discrete localized excitations in a Bose-Einstein condensate loaded into a periodic two-dimensional optical lattice, when a dipolar interaction between atoms ...

Nonlinear localized modes in dipolar Bose–Einstein condensates in two-dimensional optical lattices (Elsevier Science BV., 2016)We analyze the existence and properties of discrete localized excitations in a Bose-Einstein condensate loaded into a periodic two-dimensional optical lattice, when a dipolar interaction between atoms is present. The ...

(American Physical Society, 2015)We study existence, stability, and dynamics of linear and nonlinear stationary modes propagating in radially symmetric multicore waveguides with balanced gain and loss.We demonstrate that, in general, the system can ...
