Universality of slow decorrelation in KPZ growth [PDF]
, 2011 There has been much success in describing the limiting spatial fluctuations of growth models in the Kardar-Parisi-Zhang (KPZ) universality class. A proper rescaling of time should introduce a non-trivial temporal dimension to these limiting fluctuations.

Exploitation of SAS interferometric phase statistics for coherent change detection
Electronics Letters, 2023 Coherent change detection (CCD) takes advantage of the interferometric processing of synthetic aperture sonar (SAS) images and enables the detection of small scale changes to the scene between image pairs.

Coseismic surface deformation from air photos: The Kickapoo step over in the 1992 Landers rupture [PDF]
, 2006 Coseismic deformation of the ground can be measured from aerial views taken before and after an earthquake. We chose the area of the Kickapoo-Landers step over along the 1992 Landers earthquake zone, using air photos (scale 1:40,000) scanned at 0.4 m ...

Scattering and Diffraction in Magnetospheres of Fast Pulsars [PDF]
, 1999 We apply a theory of wave propagation through a turbulent medium to the scattering of radio waves in pulsar magnetospheres. We find that under conditions of strong density modulation the effects of magnetospheric scintillations in diffractive and ...

Saliency Detection Using Joint Temporal and Spatial Decorrelation [PDF]
, 2013 This article presents a scene-driven (i.e. bottom-up) visual saliency detection technique for videos. The proposed method utilizes non-negative matrix factorization (NMF) to replicate neural responses of primary visual cortex neurons in spatial domain. In temporal domain, principal component analysis (PCA) was applied to imitate the effect of stimulus ...

Scattering of gravitational radiation: second order moments of the wave amplitude [PDF]
, 2004 Gravitational radiation that propagates through an inhomogeneous mass distribution is subject to random gravitational lensing, or scattering, causing variations in the wave amplitude and temporal smearing of the signal.
