Effects of small surface tension in Hele-Shaw multifinger dynamics: an analytical and numerical study [PDF]

open access: yes, 2002
We study the singular effects of vanishingly small surface tension on the dynamics of finger competition in the Saffman-Taylor problem, using the asymptotic techniques described in [S. Tanveer, Phil. Trans. R. Soc. Lond. A 343, 155 (1993)]and [M. Siegel,

Wavevector selective surface [PDF]

open access: yesCLEO: 2014, 2014
Frequency selective surfaces are very well known and have been investigated in detail. Here we for the first time introduce the concept of a wavevector selective surface and demonstrate it experimentally.

Light structures phototroph, bacterial and fungal communities at the soil surface [PDF]

open access: yes, 2013
The upper few millimeters of soil harbour photosynthetic microbial communities that are structurally distinct from those of underlying bulk soil due to the presence of light. Previous studies in arid zones have demonstrated functional importance of these

Selection schemes of formation hollow parts with the taperid surface

open access: yesВестник СибАДИ, 2017
It describes different technologies obtained by cold forming of hollow parts with conical surfaces of solid and tubular billets, analyzed the advantages and disadvantages of certain methods of deformation.

Resource selection by greater sage‐grouse varies by season and infrastructure type in a Colorado oil and gas field

open access: yesEcosphere, 2022
Energy development is one of the most rapidly increasing land uses in North America, so understanding how wildlife respond to different types of energy infrastructure is crucial for informing land‐use policies.

Knot selection by boosting techniques [PDF]

open access: yes, 2006
A novel concept for estimating smooth functions by selection techniques based on boosting is developed. It is suggested to put radial basis functions with different spreads at each knot and to do selection and estimation simultaneously by a componentwise

Gradient bounds for a thin film epitaxy equation [PDF]

open access: yes, 2016
We consider a gradient flow modeling the epitaxial growth of thin films with slope selection. The surface height profile satisfies a nonlinear diffusion equation with biharmonic dissipation. We establish optimal local and global wellposedness for initial
