Concentration polarization, surface currents, and bulk advection in a microchannel [PDF]

open access: yes, 2014
We present a comprehensive analysis of salt transport and overlimiting currents in a microchannel during concentration polarization. We have carried out full numerical simulations of the coupled Poisson-Nernst-Planck-Stokes problem governing the ...

A Coefficient Test for Quintic Permutation Polynomials Over Integer Rings

open access: yesIEEE Access, 2018
For selecting appropriate permutation polynomials (PPs) in practical applications, it is necessary to know the coefficients of the polynomial since a brute-force exhaustive search is impractical when the number of PPs is large.

Differential gene expression in the oxyntic and pyloric mucosa of the young pig. [PDF]

open access: yesPLoS ONE, 2014
The stomach is often considered a single compartment, although morphological differences among specific areas are well known. Oxyntic mucosa (OXY) and pyloric mucosa (PYL, in other species called antral mucosa) are primarily equipped for acid secretion ...

Multiparametric Magnetic Resonance Imaging, Autoimmune Hepatitis, and Prediction of Disease Activity

open access: yesHepatology Communications, 2021
Noninvasive monitoring of disease activity in autoimmune hepatitis (AIH) has potential advantages for patients for whom liver biopsy is invasive and with risk.

New combinational assay using soluble fibrin and d-dimer determinations: a promising strategy for identifying patients with suspected venous thromboembolism. [PDF]

open access: yesPLoS ONE, 2014
AIM: To establish a new and reliable assay for quantification of the soluble fibrin (SF) in combination with that of D-dimer for early diagnosis of venous thromboembolism.

The speed of Arnold diffusion

open access: yes, 2013
A detailed numerical study is presented of the slow diffusion (Arnold diffusion) taking place around resonance crossings in nearly integrable Hamiltonian systems of three degrees of freedom in the so-called `Nekhoroshev regime'.

Local DRLs and automated risk estimation in paediatric interventional cardiology [PDF]

open access: yes, 2019
Introduction : Cardiac catheterization procedures result in high radiation doses and often multiple procedures are necessary for congenital heart disease patients. However, diagnostic reference levels (DRL) remain scarce.

Normal forms with exponentially small remainder: application to homoclinic connections for the reversible 02+i? resonance

open access: yesComptes Rendus. Mathématique, 2004
In this Note we explain how the normal form theorem already established (Iooss and Lombardi, J. Differential Equations, in press) for analytic vector fields with a semi-simple linearization enables to prove the existence of homoclinic connections to exponentially small periodic orbits for reversible analytic vector fields admitting a 02+i?

Some Properties of Normalized Tails of Maclaurin Power Series Expansions of Sine and Cosine

open access: yesFractal and Fractional
In the paper, the authors introduce two notions, the normalized remainders, or say, the normalized tails, of the Maclaurin power series expansions of the sine and cosine functions, derive two integral representations of the normalized tails, prove the ...
