EOS-04 (Earth Observation Satellite-04), launched on 14 February 2022, is a follow-on mission to Indian Space Research Organisation’s first synthetic aperture radar (SAR) satellite RISAT-1. It is capable of imaging in either side of the track with incidence angle range from 12.2° to 55.1°. Onboard SAR system supports variety of resolution and swath requirements and can operate in various modes like StripMap, ScanSAR and Sliding Spotlight modes with various polarization combinations like linear, hybrid and full/quad polarimetry. EOS-04 is the first spaceborne SAR mission worldwide supporting full-polarimetry (FP) data acquisitions in ScanSAR modes. Availability of FP datasets in wide swath modes (ScanSAR modes) is a big step towards scientific analysis for various applications in a timebound manner. For enabling interferometric processing, EOS-04 orbits are being maintained within the baseline requirements of 500 m. EOS-04 has 17 days repetivity resulting in less temporal decorrelation to use the datasets for various deformation studies. In addition to this, analysis ready data (ARD) product, normalized radar backscatter (NRB) Gamma0 product, are introduced to minimize the user efforts for any immediate analysis. In NRB Gamma0 products, terrain induced variations particularly on hill-slopes affecting the brightness of the radar return is normalized by applying radiometric terrain correction (RTC) on SAR images. This paper discusses about the data processing aspects related to calibration, polarimetry, interferometry and NRB Gamma0 product generation. [ABSTRACT FROM AUTHOR]

Abstract An optimal bankruptcy regime is one which avoids taking/giving loans during financial crisis, provides a provision for entrepreneurship, and further provides for achieving a maximum total value for the distressed firm. The present study is aimed at understanding the concept of optimal bankruptcy regime and its determinants in terms of merits and demerits. The study is purely of qualitative nature followed by the method of synthesis of 50 previous studies. The study concludes that the optimal bankruptcy regime that provides for the said three features is somehow or other helping economies to do well in terms of increased entrepreneurship, decreased number of liquidations, reduced NPAs’, and increased productive investments. It is also evident from several World Bank member countries that have opted for reorganisation of distressed businesses are experiencing the fruits of optimal bankruptcy regime in terms of achieving maximum value for the assets of distressed firms for about 71 cents on dollar and thereby entrepreneurship development.

Background:Medication adherence is critical for success of clinical trials. Objective:To assess oral riboflavin is an adherence marker. Methods:Riboflavin was incorporated into active treatment and placebo pills for a clinical trial lasting for 2 years. Results:The accuracy (area under the receiver operating curve) of urinary riboflavin was 0.91 as a binary classifier of adherence, and was similar or better than for two active study ingredients daidzein (0.92) and genistein (0.87) (allp < 0.0001). Decreased adherence over time was similar in the two study groups. Conclusion: Riboflavin is an accurate and useful biomarker for study pill ingestion. [ABSTRACT FROM PUBLISHER]
