Salmonella lipopolysaccharide‐containing supported lipid bilayers as platforms to study bacteriophage interactions

open access: yesFEBS Letters, EarlyView.
We present robust protocols for the preparation of supported lipid bilayers (SLBs) incorporating either Salmonella smooth LPS or outer membrane vesicles (OMVs). We use a combination of quartz crystal microbalance with dissipation (QCM‐D) and fluorescence microscopy to both characterize the SLBs of various compositions and to probe their interactions ...

Distribution functions of magnetic nanoparticles determined by a numerical inversion method

open access: yesNew Journal of Physics, 2017
In the present study, we applied a regularized inversion method to extract the particle size, magnetic moment and relaxation-time distribution of magnetic nanoparticles from small-angle x-ray scattering (SAXS), DC magnetization (DCM) and AC ...

Particle swarm optimization and its application to seismic inversion of igneous rocks

open access: yesInternational Journal of Mining Science and Technology, 2017
In order to improve the fine structure inversion ability of igneous rocks for the exploration of underlying strata, based on particle swarm optimization (PSO), we have developed a method for seismic wave impedance inversion. Through numerical simulation,

Reconstructing enzyme evolution by protein engineering

open access: yesFEBS Letters, EarlyView.
Natural enzyme evolution can be retraced by protein engineering methods such as directed evolution, rational design, and ancestral sequence reconstruction. These approaches reveal how enzymes emerged from ligand‐binding scaffolds, developed varying substrate preferences, formed oligomeric complexes, adapted to environmental changes, and evolved novel ...

A comparative study of Bagley–Torvik equation under nonsingular kernel derivatives using Weeks method

open access: yesOpen Physics
Modeling several physical events leads to the Bagley–Torvik equation (BTE). In this study, we have taken into account the BTE, including the Caputo–Fabrizio and Atangana–Baleanu derivatives. It becomes challenging to find the analytical solution to these

Numerical Modeling of Electrowetting by a Shape Inverse Approach [PDF]

open access: yesSIAM Journal on Applied Mathematics, 2009
We model an electrified droplet spreading on a solid surface. The model aims to seek a drop shape that minimizes its total energy (capillary, electrostatic, and gravitational). We derive the equations and the shape gradient; then we detail the shape optimization algorithm and present some numerical results.

The role of miR‐335‐5p in the redifferentiation of BRAF p.V600E thyroid cancers

open access: yesMolecular Oncology, EarlyView.
The BRAF p.V600E mutation promotes thyroid cancer dedifferentiation and radioiodine resistance. Using a network approach, we identified miR‐335‐5p as a key regulator of BRAF‐mutated thyroid tumors. Restoring miR‐335‐5p increased thyroid‐specific gene expression and iodine uptake in cells and organoids.

Numerical solution for nonlocal Sobolev-type differential equations

open access: yesElectronic Journal of Differential Equations, 2010
We present a numerical approximate solution to Sobolev-type differential equation subject to nonlocal initial boundary conditions. A Laplace transform method is described for the solution of considered equation.

Computer-Aided Numerical Inversion of Laplace Transform

open access: yesActive and Passive Electronic Components, 2000
This paper explores the technique for the computer aided numerical inversion of Laplace transform. The inversion technique is based on the properties of a family of three parameter exponential probability density functions.
