Auditory neuropathy is a disorder where the transmission of auditory signals from inner ear to the auditory nerve and auditory brainstem is distorted. Auditory neuropathy is not a homogenous disorder, rather, a collection of auditory abnormalities with distinctly different sites of dysfunction, diverse etiologies and causes, variations in patterns of auditory findings, and in most cases, corres...
Medical ultrasound echo signals provide the basic information for obtaining the ultrasonic image in medical ultrasound technology. The statistics of the ultrasound echo signals reveals the systematic structure of the medical ultrasonic image via analyzing the corresponding statistical distributions. A novel statistical distribution, the ascending order K distribution, was proposed here to model...
magnetic resonance imaging (mri) is a notable medical imaging technique that makes of phenomenon of nuclear magnetic resonance. because of the resolution and the technology being harmless, mri has considered as the most desirable imaging technique in clinical applications. the visual quality of mri plays an important role in accuracy of medical delineations that can be seriously degraded by exi...
Introduction:In this study, ECG signals have been embedded into medical images to create a novel blind watermarking method. The embedding is done when the original image is compressed using the EZW algorithm. The extraction process is performed at the decompression time of the watermarked image. Materials and Methods: The multi-resolution watermarking with a secret key algorithm developed in th...
in recent decades, seizure prediction caused a lot of research in both signal processing and neuroscience field. the researches tried to enhance the conventional seizure prediction algorithms such that rate of the false alarms be appropriately small so that seizures can be predicted according to clinical standards. up to now none of the proposed algorithms have been sufficiently adequate. in th...
background: behçet’s disease (bd) is a multisystemic inflammatory vasculitis of unknown etiology, and vasculitis being its major pathological feature. objectives: we studied the prevalence of microembolic signals (mes) in patients with diagnosis behçet's disease. we also tried to determine the frequency of mes in bd patients with or without neurological involvement. materials and methods: ...
abstract background and objective: hirudin is an anticoagulant polypeptide secreted from the salivary glands of leeches. recombinant hirudin is a strong anticoagulant agent in arterial and venous thrombosis. the aim of this study was to evaluate the effect of inserting protein a signal peptide sequence of pezz18 plasmid on expression and secretion of the recombinant hirudin in e.coli. ...
