Complex point source representation of real point sources
 J. Opt. Soc. Am. A
, 1989
"... A new exact representation for point sources is given in terms of complex point sources. In the simplest configuration, a point source is equivalent to a distribution of sources on the surface of a sphere in complex space. The representation can be used to consider the propagation of point disturba ..."

Nested Test for Point Sources
"... We describe an extension of a test proposed by Lampton for detecting weak and/or shortlived transient point sources in finiteresolution photonlimited maps of the sky. We test the null hypothesis that the count density is spatially uniform (i.e., no point sources) over a limited region of the sky b ..."

Pointsource scalar turbulence
 Journal of Fluid Mechanics
, 2007
"... The statistics of a passive scalar randomly emitted from a point source is investigated analytically for the Kraichnan ensemble. Attention is focused on the twopoint equaltime scalar correlation function, a statistical indicator widely used both in experiments and in numerical simulations. The onl ..."

The sources and consequences of embeddedness for the economic performance of organizations: The network effect
 American Sociological Review
, 1996
"... In this paper, I attempt to advance the concept of embeddedness beyond the level of a programmatic statement by developing a formulation that specifies how embeddedness and network structure affect economic action. On the basis of existing theory and original ethnographies of 23 apparel firms, I dev ..."

develop a systematic scheme that more fully demarcates the unique features, functions, and sources of embeddedness. From this scheme, I derive a set of refutable implications and test their plausibility, using another data set on the network ties of all better dress apparel firms in the New York apparel
gammaray point sources
, 2003
"... Abstract. We present preliminary results of a statistical analysis obtained with a sample of blazars observed at the Perugia Astronomical Observatory since 1992. We briefly show how these statistical results can be useful to discriminate faint variable sources against the background noise. This tech ..."

. This technique, together with the more traditional ones, may be used to discover and identify highenergy point sources. 1. Statistical analysis of variability Many of the expected highenergy sources are variable, like blazars which emit signals that often appear to vary chaotically with time. Does such signal
Far–infrared Point Sources
, 1999
"... Abstract. The analysis of the submm anisotropies that will be mapped by the forthcoming map and planck satellites requires careful foreground subtraction before measuring CMB fluctuations. Among these, the foreground due to IR/submm thermal radiation from dusty sources was poorly known until recent ..."

Noncommutative Point Sources
, 709
"... We construct a perturbative solution to classical noncommutative gauge theory on R3 minus the origin using the GroenewaldMoyal star product. The result describes a noncommutative point charge. Applying it to the quantum mechanics of the noncommutative hydrogen atom gives shifts in the 1S hyperfine ..."

Detection of Point Sources
"... . Photometry of individual sources requires an initial phase of detection. The detection process can be separated into two phases: (1) preprocessing of the image, and (2) actual detection, yielding a list of discrete sources. Given a distribution of background intensities, the probabilityof intensit ..."
