Alternative formulations to compute the binary shape Euler number
The authors propose two equations based on the pixel geometry and connectivity properties, which can be used to compute, efficiently, the Euler number of a binary digital image with either thick or thin boundaries.

SPATIAL HAMILTONIAN IDENTITIES FOR NONLOCALLY COUPLED SYSTEMS
We consider a broad class of systems of nonlinear integro-differential equations posed on the real line that arise as Euler–Lagrange equations to energies involving nonlinear nonlocal interactions.

Incompressible limit for non-isentropic compressible Euler-Navier-Stokes two-phase flow model in R^3
This article concerns the incompressible limit for the two-phase flow model consisting of the compressible isothermal Euler equations coupled with compressible non-isentropic Navier-Stokes equations through a drag forcing term. For the 3D Cauchy problem,

Note on the q-Extension of Barnes' Type Multiple Euler Polynomials
We construct the q-Euler numbers and polynomials of higher order, which are related to Barnes' type multiple Euler polynomials. We also derive many properties and formulae for our q-Euler polynomials of higher order by using the multiple integral ...
