Prognostic Value of Systemic Inflammatory Biomarkers in Patients Undergoing Cytoreductive Surgery with Hyperthermic Intraperitoneal Chemotherapy

D.C. Hanna, Muhammad Owais Abdul Ghani, Alexander S Mina, Andrew M Hermina et autres

Introduction: Cytoreductive surgery with hyperthermic intraperitoneal chemotherapy (CRS-HIPEC) is a popular, but morbid, treatment for patients with peritoneal carcinomatosis. Thus, patient selection and prognostication are important. This study aims to evaluate three laboratory values, blood neutrophil to lymphocyte ratio (NLR), platelet to …

VERITAS Discovery of Very High Energy Gamma-Ray Emission from S3 1227+25 and Multiwavelength Observations

A. Acharyya, Colin Adams, Avery Archer, P. Bangale et autres

We report the detection of very high energy gamma-ray emission from the blazar S3 1227+25 (VER J1230+253) with the Very Energetic Radiation Imaging Telescope Array System (VERITAS). VERITAS observations of the source were triggered by the detection of a hard-spectrum GeV flare …

A Versatile Polynomial Model for Reflection by a Reflective Intelligent Surface with Varactors

D.C. Hanna, Miguel Saavedra Melo, Feiyu Shan, Filippo Capolino

An analytical model for reflection of a reconfigurable intelligent surface (RIS) using varactors to adjust the reflection phase of an incident plane wave is presented. The model results are compared to a full-wave RIS simulation for different varactor bias voltages. The model …
