Instability of standing waves for the inhomogeneous Gross-Pitaevskii equation

open access: yesAIMS Mathematics, 2020
In this paper, we consider the instability of standing waves for an inhomogeneous Gross-Pitaevskii equation \[ i\psi_t +\Delta \psi -a^2|x|^2\psi +|x|^{-b}|\psi|^{p}\psi=0. \] This equation arises in the description of nonlinear waves such as propagation

Exact Bond-Located Spin Ground State in the Hubbard Chain with Off-Diagonal Coulomb Interactions

open access: yes, 2001
We show the existence of an exact ground state in certain parameter regimes of one-dimensional half-filled extended Hubbard model with site-off-diagonal interactions. In this ground state, the bond-located spin correlation exhibits a long-range order. In

The ground-state of the Se2 molecule [PDF]

open access: yesProceedings of the Indian Academy of Sciences - Section A, 1937
THE diatomic molecules of the lighter elements of the sixth family of the Periodic Table, like O2, S2, SO, have 3Σ terms as their ground states. There is some doubt if this still prevails with the heavier elements of that group. Spectroscopic investigations have so far not been able to show whether the ground states of Se2, Te2, SeO, etc., are 3Σ or 1Σ

Structural dynamics of the plant hormone receptor ETR1 in a native‐like membrane environment

open access: yesFEBS Letters, EarlyView.
The present study unveils the structural and signaling dynamics of ETR1, a key plant ethylene receptor. Using an optimized nanodisc system and solution NMR, we captured full‐length ETR1 in a native‐like membrane environment. Our findings reveal dynamic domain uncoupling and Cu(I)‐induced rigidification, providing the first evidence of metal‐triggered ...

Inhomogeneous NLS with partial harmonic confinement

open access: yesAIMS Mathematics
We investigate the inhomogeneous nonlinear Schrödinger equation with partial harmonic confinement. First, we present a global well-posedness result for small data in the intercritical regime.

Existence of ground state solutions for a class of quasilinear elliptic systems in Orlicz-Sobolev spaces

open access: yesBoundary Value Problems, 2017
In this paper, we investigate the following nonlinear and non-homogeneous elliptic system: { − div ( a 1 ( | ∇ u | ) ∇ u ) + V 1 ( x ) a 1 ( | u | ) u = F u ( x , u , v ) in  R N , − div ( a 2 ( | ∇ v | ) ∇ v ) + V 2 ( x ) a 2 ( | v | ) v = F v ( x , u ,

A working model for cytoplasmic assembly of H/ACA snoRNPs

open access: yesFEBS Letters, EarlyView.
Dyskerin is the component of nuclear H/ACA ribonucleoproteins (RNPs) endowed with pseudouridine synthase catalytic activity. Two isoforms of human dyskerin have been characterized: the abundant Iso1, mainly nuclear, and the shorter Iso3, mainly cytoplasmic but occasionally imported into nuclei.

Optical Response and Ground State of Graphene

open access: yes, 2011
The optical response and the ground state of graphene and graphene-like systems are determined self-consistently. Deriving equations of motion for the basic variables, graphene Bloch equations are introduced and combined with a variational Ansatz for the

Comparing self‐reported race and genetic ancestry for identifying potential differentially methylated sites in endometrial cancer: insights from African ancestry proportions using machine learning models

open access: yesMolecular Oncology, EarlyView.
Integrating ancestry, differential methylation analysis, and machine learning, we identified robust epigenetic signature genes (ESGs) and Core‐ESGs in Black and White women with endometrial cancer. Core‐ESGs (namely APOBEC1 and PLEKHG5) methylation levels were significantly associated with survival, with tumors from high African ancestry (THA) showing ...

Glueballs and mesons: The ground states [PDF]

open access: yesPhysical Review D, 2009
We provide a new, independent, and analytic estimate of the lowest glueball mass, and we found it at 1661 MeV within a relativistic quantum-field model based on analytic confinement. The conventional mesons and the weak decay constants are described to extend the consideration. For the spectra of two-gluon and two-quark bound states we solve the ladder
