High-resolution animal location data are increasingly available, requiring analytical approaches and statistical tools that can accommodate the temporal structure and transient dynamics (non-stationarity) inherent in natural systems. Traditional analyses often assume uncorrelated or weakly correlated temporal structure in the velocity (net displacement) time series constructed using sequential ...

We have searched for discrete refractive scattering events (including effects due to possible nonmultiple diffractive scattering) at meter wavelengths in the direction of two close by pulsars B0950+08 and B1929+10, where we looked for spectral signatures associated with the multiple imaging of pulsars due to scattering in the interstellar medium. We do not find any signatures of such events in ...

We obtained 238 spectra of the close orbiting extrasolar giant planet HD 189733b with resolution R ∼ 15, 000 during one night of observations with the near infrared spectrograph, NIRSPEC, at the Keck II Telescope. We have searched for planetary absorption signatures in the 2.0 μm 2.4 μm region where H2O and CO are expected to be the dominant atmospheric opacities. We employ a phase dependent or...

The IR microspectra for individual normal and cancerous cells are reported at a spatial resolution that permits a distinction between the nuclear and cytoplasmic regions. The observed spectra reveal large differences in the spectral contributions of RNA, DNA, and phospholipids: metabolically inactive cells show spectral patterns of proteins only, whereas actively dividing cells also show spectr...

An important source of opacity in exoplanet atmospheres at short visible and near-UV wavelengths is Rayleigh scattering of light on molecules. It is accompanied by a related, albeit weaker process – Raman scattering. We analyze the signatures of Raman scattering imprinted in the reflected light and the geometric albedo of exoplanets, which could provide information about atmospheric properties....

Layered reflectivity sequences have spectral signatures (impulse responses) in accordance with timefrequency transformations. These signatures are filtered by a source under the convolutional definition of a seismogram. Spectral signatures of wedge models indicate that thin layers have preferred source bandwidths needed to produce either a tuned reflection or separate interface reflections. Sou...
