Soil permittivity estimation using Polarimetric Synthetic Aperture Radar (PolSAR) data has been an extensively researched area. Nonetheless, it provides ample scope for further improvements. The vegetation cover over the soil surface leads to a complex interaction of incident polarized wave with canopy and subsequently underlying surface. This paper introduces novel methodology estimate croplan...

In radar polarimetry, incoherent target decomposition techniques help extract scattering information from polarimetric synthetic aperture (SAR) data. This is achieved either by fitting appropriate models or optimizing the received wave intensity through diagonalization of coherency (or covariance) matrix. As such, depends on antenna configuration. Additionally, a descriptor that independent con...

Many patients show no or incomplete responses to current pharmacological or psychological therapies for depression. Here we explored the feasibility of a new brain self-regulation technique that integrates psychological and neurobiological approaches through neurofeedback with functional magnetic resonance imaging (fMRI). In a proof-of-concept study, eight patients with depression learned to up...

BACKGROUND Affective disorders provide for one third of the main causes of psychiatric inpatient care, both in male and female subjects. An early diagnosis of the disease with precise identification of the character of its particular symptoms are key important factors for the efficacy of treatment. The goal of the study was an identification of possible associations between scores of the neurot...
