This research depicts another artificial neural network (ANN) based digital differential protection scheme for generator stator winding protection. The scheme incorporates two feedforward neural networks (FNNs). One ANN is utilized for flaw recognition and the other is utilized for inward deficiency grouping. This structure utilizes current examples from the line-side and the unbiased end notwithstanding tests from the field current. Essential and/or second consonant present in the field current during an issue help the ANN, utilized for flaw location, to separate between generator states (typical, outside issue and interior deficiency states). Results demonstrating the performance of the protection scheme are displayed and show that it is quick and solid.

Simultaneous liver abscesses are rarely seen and reported. We are reporting a case of two simultaneous, complex liver abscesses in a patient who had no evidence of liver abscess on cross-sectional imaging close to three months prior to this presentation. These abscesses were 7-8 cm in size, large, and septated. Microbiological studies were positive for Streptococcus constellatus, which is a known cause of pyogenic liver abscess. In our patient, pyogenic liver abscesses were associated with bacteremia and sepsis. This patient was managed with broad spectrum parenteral antibiotics and percutaneous drainage with improvement in clinical condition. This patient was discharged home with a peripherally inserted central catheter (PICC) line in place to complete a six-week course of parenteral antibiotics. A complete history and physical with pertinent examination findings are key to diagnosis of liver abscess. S. constellatus should be considered in the differential diagnosis of patients with liver abscess and sepsis.

Primary lymphoma of the liver is extremely rare, and is more common among immunocompromised patients. It typically occurs after the fifth decade of life and has a male predominance. It often presents with diagnostic difficulties to both clinicians and pathologists as most cases have a solitary or multiple mass lesions in the liver with normal alpha-fetoprotein levels. Chemotherapy is the standard of therapy. Here, we describe a unique case of primary hepatic lymphoma in an elderly immunocompetent female who presented with symptomatic hypercalcemia.
