An embedding scheme for the Dirac equation

, 2004
An embedding scheme is developed for the Dirac Hamiltonian H. Dividing space into regions I and II separated by surface S, an expression is derived for the expectation value of H which makes explicit reference to a trial function defined in I alone, with

Parent‐to‐Child Information Disclosure in Pediatric Oncology

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background Despite professional consensus regarding the importance of open communication with pediatric cancer patients about their disease, actual practice patterns of disclosure are understudied. Extant literature suggests a significant proportion of children are not told about their diagnosis/prognosis, which is purported to negatively ...

Existence and stability of a positive solution for nonlinear hybrid fractional differential equations with singularity

Journal of Taibah University for Science, 2019
In this paper, we will study solution existence and its stability for hybrid fractional DE with fractional integral, fractional differential derivative and Φp-operator in Caputo sense.

Fermi arcs and hidden zeros of the Green function in the pseudogap state [PDF]

, 2005
We investigate the low-energy properties of a correlated metal in the proximity of a Mott insulator within the Hubbard model in two dimensions. We introduce a version of the cellular dynamical mean-field theory using cumulants as the basic irreducible ...

Low-energy expansion formula for one-dimensional Fokker-Planck and Schr\"odinger equations with periodic potentials

, 2011
We study the low-energy behavior of the Green function for one-dimensional Fokker-Planck and Schr\"odinger equations with periodic potentials. We derive a formula for the power series expansion of reflection coefficients in terms of the wave number, and ...

A Systematic Review of Evidence on the Clinical Effectiveness of Surveillance Imaging in Children With Medulloblastoma and Ependymoma

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Surveillance imaging aims to detect tumour relapse before symptoms develop, but it's unclear whether earlier detection of relapse leads to better outcomes in children and young people (CYP) with medulloblastoma and ependymoma. This systematic review aims to identify relevant literature to determine the efficacy of surveillance magnetic ...

Existence Results for Some p-Laplacian Langevin Problems with a ψ-Hilfer Fractional Derivative with Antiperiodic Boundary Conditions

Fractal and Fractional
In this work, we establish the existence of at least one solution for a p-Laplacian Langevin differential equation involving the ψ-Hilfer fractional derivative with antiperiodic boundary conditions. More precisely, we transform the studied problem into a

Existence Result and Uniqueness for Some Fractional Problem

Mathematics, 2019
In this article, by the use of the lower and upper solutions method, we prove the existence of a positive solution for a Riemann−Liouville fractional boundary value problem. Furthermore, the uniqueness of the positive solution is given.

Green Function on the q-Symmetric Space SU_q(2)/U(1)

, 1997
Following the introduction of the invariant distance on the non-commutative C-algebra of the quantum group SU_q(2), the Green function and the Kernel on the q-homogeneous space M=SU(2)_q/U(1) are derived. A path integration is formulated.
