Due to the limitations of horizontal bounding boxes for locating oriented ship targets in synthetic aperture radar (SAR) images, rotated box (RBB) has received wider attention recent years. First, existing RBB encodings suffer from boundary discontinuity problems, which interfere with convergence model, and then lead some such as inaccurate location state. Thus, perspective that long-edge features ships are more representative their orientation, decomposition encoding been proposed this...

Abstract The epidermal growth factor receptor (EGFR) is a cell-surface tyrosine kinase that belongs to the ERBB family, which includes HER1 (EGFR), HER2, HER3, and HER4. Each of these receptors has three key layers: an input layer, signal-processing core, output layer. EGFR activated primarily through ligand binding, with ligands such as EGF, TGF-alpha, HB-EGF, AR, EPR, BTC, epigen. However, mutations or overexpression can lead ligand-independent activation. Once activated, triggers various...
