Inclusions and inhomogeneities under stress

open access: yesPhilosophical Magazine Letters, 1996
Some general theorems, new and old, concerning the behaviour of elastic inclusions and inhomogeneities in bodies without or with external stress, are assembled. The principal new result is that arbitrary external tractions cannot influence the shape of an inclusion, because the elastic field of the external tractions passes unperturbed through the ...

A Unified Point Process Probabilistic Framework to Assess Heartbeat Dynamics and Autonomic Cardiovascular Control

open access: yesFrontiers in Physiology, 2012
In recent years, time-varying inhomogeneous point process models have been introduced for assessment of instantaneous heartbeat dynamics as well as specific cardiovascular control mechanisms and hemodynamics.

Coupling aerosol optics to the MATCH (v5.5.0) chemical transport model and the SALSA (v1) aerosol microphysics module [PDF]

open access: yesGeoscientific Model Development, 2016
A new aerosol-optics model is implemented in which realistic morphologies and mixing states are assumed, especially for black carbon particles. The model includes both external and internal mixing of all chemical species, it treats externally mixed black

Inhomogeneous phases in the Nambu-Jona-Lasino and quark-meson model

open access: yes, 2009
We discuss inhomogeneous ground states of the Nambu-Jona-Lasino (NJL) and quark-meson (QM) model within mean-field approximation and their possible existence in the respective phase diagrams. For this purpose we focus on lower dimensional modulations and

Polynomial Cohomology and Polynomial Maps on Nilpotent Groups [PDF]

open access: yes, 2019
We introduce a refined version of group cohomology and relate it to the space of polynomials on the group in question. We show that the polynomial cohomology with trivial coefficients admits a description in terms of ordinary cohomology with polynomial ...

The recursive Green's function method for graphene

open access: yes, 2013
We describe how to apply the recursive Green's function method to the computation of electronic transport properties of graphene sheets and nanoribbons in the linear response regime.

Detection of aortic wall inclusions using regional pulse wave propagation and velocity in silico

open access: yesArtery Research, 2012
Monitoring of the regional stiffening of the arterial wall may prove important in the diagnosis of various vascular pathologies. The pulse wave velocity (PWV) along the aortic wall has been shown to be dependent on the wall stiffness and has played a ...

The Forces Driving Streaming in the Presence of Scatterers Mimicking the Blood Cells and the Contrast Agents

open access: yesArchives of Acoustics, 2019
Acoustical Driving Forces (ADF), induced by propagating waves in a homogeneous and inhomogeneous lossy fluid (suspension), are determined and compared depending on the concentration of suspended particles.

A microscopic approach to critical phenomena at interfaces: an application to complete wetting in the Ising model

open access: yes, 2004
We study how the formalism of the Hierarchical Reference Theory (HRT) can be extended to inhomogeneous systems. HRT is a liquid state theory which implements the basic ideas of Wilson momentum shell renormalization group (RG) to microscopic Hamiltonians.

QCD S Parameter from Inhomogeneous Bethe-Salpeter Equation [PDF]

open access: yes, 1994
We calculate the low-energy parameter S in QCD, which is also known as L_{10}, and the pion decay constant f_\pi using inhomogeneous Bethe-Salpeter equation in improved ladder approximation.
