The action of linear media on incident polarized electromagnetic waves can produce two kinds thermodynamic irreversible effects, namely, loss intensity, in general anisotropic, and reduction the degree polarization. Even though both phenomena be described through specific properties, overall reversibility polarimetric interactions characterized by means a single parameter whose minimum maximum ...

This contribution is concerned with the mathematical formulation and theoretical background of the Gers̆gorin theory in the context of Radar Polarimetry. Named after its founder Semian A. Gers̆gorin the Gers̆gorin theorem basically states that there are certain regions in the complex plane that can be derived from any n × n complex matrix by rather simple arithmetic operations. These regions are c...

Advantages of the e−e− option at linear colliders for the study of supersymmetry are highlighted. The fermion number violating process e−e− → ẽ−ẽ− provides unique opportunities for studies of slepton masses and flavor mixings. In particular, slepton mass measurements at the 100 MeV level through threshold scans of scalar pair production may be possible. Such measurements are over an order of ma...

OBJECTIVES Subjective visual deficits are common after demyelinating optic neuritis despite the frequent return of normal visual acuity. Visual and electrodiagnostic tests have demonstrated evidence of these persisting functional abnormalities, which are thought to be secondary to demyelination and variable axonal loss in the optic nerve. Scanning laser polarimetry (SLP) is a new image analysis...

The discovery of SN 2002ic and subsequent spectroscopic studies have led to the surprising finding that SN 2002ic is a Type Ia supernova with strong ejectacircumstellar interaction. Here we show that nearly 1 year after the explosion the supernova has become fainter overall, but the Hα emission has brightened and broadened dramatically compared to earlier observations. We have obtained spectrop...

AIMS To evaluate different algorithms used to analyse retinal nerve fibre layer thickness (RNFL) data obtained by scanning laser polarimetry, in order to compare their relative abilities to discriminate between patients with glaucomatous localised nerve fibre layer defects and normal subjects. METHODS 48 eyes of 48 glaucomatous patients with localised RNFL defects and 53 eyes of 53 healthy su...

We present the results of wide-field JHKS polarimetry toward the H II region S106 using the IRSF (Infrared Survey Facility) telescope. Our polarimetry data revealed an extended (up to ∼ 5) polarized nebula over S106. We confirmed the position of the illuminating source of most of the nebula as consistent with S106 IRS 4 through an analysis of polarization vectors. The bright portion of the pola...

Fluctuations in atmospheric emission introduce noise and systematic errors into measurements of polarization at far-infrared and submillimeter wavelengths. We describe a new analysis method that corrects for the bias and reduces the errors caused by the fluctuations. The method exploits repeated observations of a source and is especially effective on faint sources for which the polarized flux i...
