Analytic Solutions in Nonlinear Massive Gravity [PDF]

open access: yesPhysical Review Letters, 2011
We study spherically symmetric solutions in a covariant massive gravity model, which is a candidate for a ghost-free non-linear completion of the Fierz-Pauli theory. There is a branch of solutions that exhibits the Vainshtein mechanism, recovering General Relativity below a Vainshtein radius given by $(r_g m^2)^{1/3}$, where $m$ is the graviton mass ...

Exploring the relevance of the type of horizontal separator to optimize the extraction efficacy for the Arbequina variety

open access: yesFrontiers in Plant Science
The productivity of virgin olive oil depends not only on agronomic factors but also on the technological factors of the extraction process. The ‘Arbequina’ variety has extractability problems, which is a challenge for master millers anywhere.

Formal analytical solutions for the Gross-Pitaevskii equation

open access: yes, 2007
Considering the Gross-Pitaevskii integral equation we are able to formally obtain an analytical solution for the order parameter $\Phi (x)$ and for the chemical potential $\mu $ as a function of a unique dimensionless non-linear parameter $\Lambda $.

Enzyme kinetics for a two-step enzymic reaction with comparable initial enzyme-substrate ratios [PDF]

open access: yes, 1988
We extend the validity of the quasi-steady state assumption for a model double intermediate enzyme-substrate reaction to include the case where the ratio of initial enzyme to substrate concentration is not necessarily small.

Analytical solution of cross polarization dynamics [PDF]

open access: yesJournal of Magnetic Resonance, 2015
Cross polarization (CP) dynamics, which was remained unknown for five decades, has been derived analytically in the zero- and double-quantum spaces. The initial polarization in the double-quantum space is a constant of motion under strong pulse condition ($| _{1I}+ _{1S}|\gg |d(t)|$), while the Hamiltonian in the zero-quantum space reduces to $d(t ...

The MedSupport Multilevel Intervention to Enhance Support for Pediatric Medication Adherence: Development and Feasibility Testing

open access: yesPediatric Blood &Cancer, EarlyView.
ABSTRACT Introduction We developed MedSupport, a multilevel medication adherence intervention designed to address root barriers to medication adherence. This study sought to explore the feasibility and acceptability of the MedSupport intervention strategies to support a future full‐scale randomized controlled trial.

Orientation Mapping of Extruded Polymeric Composites by Polarized Micro-Raman Spectroscopy

open access: yesJournal of Spectroscopy, 2015
Molecular orientation has a strong influence on polymeric composite materials’ mechanical properties. In this paper we describe the use of polarized micro-Raman spectroscopy as a powerful tool to map out the molecular orientation of a uniaxially oriented

Analytical Solutions to Temperature Field in Various Relative-Scale Media Subjected to a Reciprocating Motion Point Heat Source

open access: yesApplied Sciences, 2022
To reveal the temperature rise evolution mechanism of isotropic media subjected to reciprocating motion constant-strength point heat source, various forms of analytical solutions are derived on the basis of differentiated relative scales, and non ...

Analytical solutions of bound timelike geodesic orbits in Kerr spacetime

open access: yes, 2012
We derive the analytical solutions of the bound timelike geodesic orbits in Kerr spacetime. The analytical solutions are expressed in terms of the elliptic integrals using Mino time $\lambda$ as the independent variable.
