Abstract An optimal power allocation (OPA) policy for orthogonal frequency division multiplexing (OFDM)-based cognitive radio networks (CRNs) using underlay spectrum access model is presented under multiple secondary users (SUs) with energy harvesting (EH).The proposed algorithm can allocate transmission power to each SU on each subcarrier with the
Abstract Background Aldo-keto reductase family 1 member C3 (AKR1C3) is a radioresistance gene in esophageal cancer.This study aimed to investigate the signaling pathways that mediate the regulatory role of AKR1C3 in the radioresistance of esophageal cancer cells.Methods The protein levels of AKR1C3 in cancer tissue samples were compared between pat
The proteins S100A9 and S100A12 are associated with the human S100 calcium-binding protein family.These proteins promote interaction with target proteins and alter their conformation when they bind to calcium ions in Reclining Sofa EF-hand motifs.The V domain of RAGE (Receptor for Advanced Glycation End products) is crucial for S100A9 binding.The b
