Local and global low-regularity solutions to generalized Leray-alpha equations

Electronic Journal of Differential Equations, 2015
It has recently become common to study approximating equations for the Navier-Stokes equation. One of these is the Leray-alpha equation, which regularizes the Navier-Stokes equation by replacing (in most locations) the solution u with $(1-\alpha^2 ...

Ricardian equivalence and the intertemporal Keynesian multiplier [PDF]

We show that Keynesian multiplier effects can be obtained in dynamic optimizing models if one combines both price rigidities and a "non Ricardian" framework where, due for example to the birth of new agents, Ricardian equivalence does not hold.multiplier

Designing Wire Mazes for Replicating Natural Echoes to Study Bat Biosonar Function

Advanced Intelligent Systems, EarlyView.
A validated framework combining efficient physical modeling (multiple scattering model) and deep learning is presented to guide wire‐maze design for bat biosonar studies. This approach rapidly generates large datasets to test acoustic distinguishability among wire arrangements.

On homogenization of the Lavrent’ev-Bitsadze equation in a partially perforated domain with the third boundary condition on the boundary of the cavities. Subcritical, critical and supercritical cases

Современная математика: Фундаментальные направления
For the Lavrent’ev—Bitsadze equation in a partially perforated model domain with a characteristic size of microinhomogeneities \(\varepsilon,\) we consider the problem with the third-kind boundary condition on the boundary of the cavities (the Fourier ...

On Integral Operators with Operator-Valued Kernels

Journal of Inequalities and Applications, 2010
Here, we study the continuity of integral operators with operator-valued kernels. Particularly we get estimates under some natural conditions on the kernel , where and are Banach spaces, and and are positive measure spaces: Then, we apply ...

On the growth of Fourier multipliers

Journal of Noncommutative Geometry
We define a sequence of functions, namely, tame cuts, in the Fourier algebra A(G) of a locally compact group G , which satisfies certain convergence and growth ...

Electrokinetic Stabilization of Formation Fines Using Surface Modified Polymer Silica Nanocomposites During Low Salinity Water Flooding for Enhanced Oil Recovery

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Fines migration induced by low salinity water flooding severely impairs reservoir permeability and injectivity presenting a critical challenge in enhanced oil recovery. This study aims to synthesize and evaluate a surface‐modified polymer‐silica nanocomposite to mitigate clay mobilization and preserve the hydrodynamic capacity of porous media.
