Jupiter's radiation belts at 13.8 GHz
No full textThe Jupiter flyby of Cassini in 2001 allowed to study the gas giant in detail. Jupiter’s inner magnetosphere is populated by high energy particles, causing an intense radiation observable throughout the microwave regime. The re-calibration of the Cassini RADAR instrument has allowed for constraining the energy distribution of the electron population indicating a lack of high energy particles. Maps of the synchrotron radiation indicate a redistribution of the electrons compared to other epochs, confirming that the magnetosphere was in a highly disturbed stat. The retrieval accounted for the thermal emission from Jupiter and required depleting the polar regions of ammonia.Aerospace EngineeringSpace Engineerin

Application of digital pathology and machine learning in the liver, kidney and lung diseases
No full textThe development of rapid and accurate Whole Slide Imaging (WSI) has paved the way for the application of Artificial Intelligence (AI) to digital pathology. The availability of WSI in the recent years allowed the rapid development of various AI technologies to blossom. WSI-based digital pathology combined with neural networks can automate arduous and time-consuming tasks of slide evaluation. Machine Learning (ML)-based AI has been demonstrated to outperform pathologists by eliminating inter- and intra-observer subjectivity, obtaining quantitative data from slide images, and extracting hidden image patterns that are relevant to disease subtype and progression. In this review, we outline the functionality of different AI technologies such as neural networks and deep learning and discover how aspects of different diseases make them benefit from the implementation of AI. AI has proven to be valuable in many different organs, with this review focusing on the liver, kidney, and lungs. We also discuss how AI and image analysis not only can grade diseases objectively but also discover aspects of diseases that have prognostic value. In the end, we review the current status of the integration of AI in pathology and share our vision on the future of digital pathology

Renal recovery following orthotopic liver transplant after prolonged kidney injury: Perspectives on diagnosing hepatorenal syndrome and determining which patients should undergo simultaneous liver kidney transplantation
No full textWe present a case of an individual with cirrhosis and renal failure. This case is notable because the patient was found to have hepatorenal syndrome (HRS) superimposed on Immunoglobulin A (IgA) nephropathy. After 8 months of dialysis, the patient had significant renal recovery following orthotopic liver transplant (OLT). Cases such as this are not likely to be rare, as case series have shown that IgA deposits are a common occurrence in patients with cirrhosis, including those who have HRS. While current diagnostic criteria for HRS emphasize the importance of excluding glomerular lesions, we argue that this approach should be reconsidered. More specifically, we feel that the diagnostic approach to HRS should be more inclusive of cases in which patients have simultaneous HRS and glomerular injury. In addition, our case highlights the challenges in determining which patients will benefit most from simultaneous liver–kidney transplants over OLTs alone
