Detection of Alzheimer's Dementia by Using Signal Decomposition and Machine Learning Methods.

Dementia is one of the most common neurological disorders causing defection of cognitive functions, and seriously affects the quality of life. In this study, various methods have been proposed for the detection and follow-up of Alzheimer's dementia (AD) with advanced signal processing methods by using electroencephalography (EEG) signals. Signal decomposition-based approaches such as empirical mode decomposition (EMD), ensemble EMD (EEMD), and discrete wavelet transform (DWT) are presented to classify EEG segments of control subjects (CSs) and AD patients.

Epileptic EEG Classification by Using Time-Frequency Images for Deep Learning.

Epilepsy is one of the most common brain disorders worldwide. The most frequently used clinical tool to detect epileptic events and monitor epilepsy patients is the EEG recordings. There have been proposed many computer-aided diagnosis systems using EEG signals for the detection and prediction of seizures.

Classification of Epileptic EEG Signals Using Synchrosqueezing Transform and Machine Learning.

Epilepsy is a neurological disease that is very common worldwide. Patient's electroencephalography (EEG) signals are frequently used for the detection of epileptic seizure segments. In this paper, a high-resolution time-frequency (TF) representation called Synchrosqueezing Transform (SST) is used to detect epileptic seizures.

An important procedure in ossiculoplasty: autoclaving the ossicles.

Autoclaving of the ossicles prior to ossiculoplasty is a very important procedure in surgery of cholesteatomatous chronic otitis media. Autoclaving allows the reuse of the ossicles removed from patients with cholesteatomatous chronic otitis media as an autograft. It also allows utilization of the malleus, incus and stapes taken from cadavers or of the uneroded malleus and incus removed from patients undergoing non-functional middle ear surgery chosen carefully with detailed history and laboratory analysis.

Can homograft ossicles still be used in ossiculoplasty?

The use of ossicular homografts has been legally forbidden in many countries for the last five years. In Turkey, imported ossicular biomaterials are very expensive. Malleus and incus homografts were mostly obtained during non-functional ear microsurgery on selected patients using a detailed history and special preoperative tests to avoid the risk of virus contamination.
