This paper gives details of image quality analysis of ASAR image mode IMP VV polarisation products performed during the ASAR commissioning phase. Initially, a description of the analysis methodology and performance assessment tools, image properties and example IMP products is given followed by the image quality analysis. This analysis includes format verification, impulse response function mea...

Resonant scattering of plane waves by a periodic slab under conditions close to those that support a guided mode is accompanied by sharp transmission anomalies. For two-dimensional structures, we establish sufficient conditions, involving structural symmetry, under which these anomalies are characterized by total transmission and total reflection at frequencies separated by an arbitrarily small...

Stress waves contain useful information about the properties of porous materials; they can be recovered through different non-destructive testing methods such as crosswell, vertical seismic profile, borehole logging as well as sonic tests. In all these methods, it is crucial to assess the effects of frequency on wave attributes including velocity and intrinsic attenuation. The dependency of per...

Background: To assess the effectiveness of repeated transvaginal ultrasound-guided ovarian interstitial laser treatment in the management of anovulatory patients with polycystic ovary syndrome (PCOS). Materials and Methods: A retrospective study was performed in our department on 27 anovulatory PCOS women who failed to respond to the first ultrasound-guided transvaginal ovarian interstitial las...

Introduction: The nucleus accumbens is involved in various functions ranging from motivation and reward to feeding and drug addiction. Some researchers have also suggested that this region has some roles in consciousness. In the present study, the effect of electrical stimulation and lesion of nucleus accumbens on Electroencephalogram waves (EEG) of addict and non-addict rats was investigated. ...
