Double negative differential thermal resistance induced by the nonlinear on-site potentials

, 2012
We study heat conduction through one-dimensional homogeneous lattices in the presence of the nonlinear on-site potentials containing the bounded and unbounded parts, and the harmonic interaction potential.

Arabidopsis root apical meristem adaptation to an osmotic gradient condition: an integrated approach from cell expansion to gene expression

Frontiers in Plant Science
Climate change triggers abiotic stress, such as drought and high salinity, that can cause osmotic stress. Water availability can limit plant growth, and the root tip tissues initially sense it.

Spectral Localization by Gaussian Random Potentials in Multi-Dimensional Continuous Space

, 2000
A detailed mathematical proof is given that the energy spectrum of a non-relativistic quantum particle in multi-dimensional Euclidean space under the influence of suitable random potentials has almost surely a pure-point component.

Necessary conditions for classical super-integrability of a certain family of potentials in constant curvature spaces

, 2010
We formulate the necessary conditions for the maximal super-integrability of a certain family of classical potentials defined in the constant curvature two-dimensional spaces.

From the Birkhoff-Gustavson normalization to the Bertrand-Darboux integrability condition

, 2000
The Bertrand-Darboux integrability condition for a certain class of perturbed harmonic oscillators is studied from the viewpoint of the Birkhoff-Gustavson(BG)-normalization: By solving an inverse problem of the BG-normalization on computer algebra, it is

Homogenization of random parabolic operator with large potential

Stochastic Processes and their Applications, 2001
The homogenization problem for a random parabolic operator with a large potential and with coefficients rapidly oscillating both in time and space is investigated. Namely, a Cauchy problem \[ u^ {\varepsilon }_ {t}(t,x) = \operatorname {div}\left [ a\Bigl ({x\over \varepsilon },\xi (\varepsilon ^ {-\alpha }t)\Bigr ) \nabla u^ {\varepsilon }(t,x)\right ]

COSMOLOGICAL PERTURBATIONS IN PRESENCE OF SCALAR FIELDS

Odessa Astronomical Publications, 2014
We investigate the role of the scalar field assuming its presence at late stages of the Universe evolution together with dust presented by a system of an arbitrary number of gravitating masses (galaxies, groups of galaxies and clusters of galaxies) and ...

Dynamics of quintessence in generalized uncertainty principle

European Physical Journal C: Particles and Fields, 2020
We investigate the quintessence scalar field model modified by the generalized uncertainty principle in the background of a spatially flat homogeneous and isotropic universe. By performing a dynamical system analysis we examine the nature of the critical

Rapidly Rotating Bose-Einstein Condensates in Homogeneous Traps

, 2007
We extend the results of a previous paper on the Gross-Pitaevskii description of rotating Bose-Einstein condensates in two-dimensional traps to confining potentials of the form V(r) = r^s ...

Integration of consonant and pitch processing as revealed by the absence of additivity in mismatch negativity. [PDF]

PLoS ONE, 2012
Consonants, unlike vowels, are thought to be speech specific and therefore no interactions would be expected between consonants and pitch, a basic element for musical tones.
