Point sources of air pollution [PDF]
Occupational Medicine, 2005 Many people live near point sources of air pollution such as industrial sites and waste disposal operations and there are often suggestions of clusters of disease around such activities. Such alleged clusters will generate significant public concern and media interest and in many cases will warrant detailed investigation.

A note on point source diffraction by a wedge [PDF]
, 2004 The object of this paper is to give new expressions for the wave field produced when a time harmonic point source is diffracted by a wedge with Dirichlet or Neumann boundary conditions on its faces.

Point-Source Geometric Metasurface Holography
Nano Letters, 2020 Geometric metasurfaces have shown great potential in holography due to their straightforward geometric nature of phase control. The incident angles, spins, and wavelengths of the light provide various degrees of freedom to multiplex metasurface holographic images, which, however, are usually interrelated and hence challenging to be fully decoupled ...

Lattice gases with a point source
, 2014 We study diffusive lattice gases with local injection of particles, namely we assume that whenever the origin becomes empty, a new particle is immediately injected into the origin.
