This study investigates phase relationships between electrocorticogram (ECoG) signals through Hilbert-Huang Transform (HHT), combined with Empirical Mode Decomposition (EMD). We perform spatial and temporal filtering of the raw signals, followed by tuning the EMD parameters. It can be seen that carefully tuning of EMD filter, it is possible to capture distinct features of non-stationary data. T...
Neurologic Manifestation as Initial Presentation in a Case of Hereditary Haemorrhagic Telangiectasia
Hereditary Haemorrhagic Telangiectasia (HHT), or Osler-Weber-Rendu syndrome is an uncommon autosomal dominant multi-organ condition of vascular dysplasias. We describe a 19 year old Indian female who presented with cerebral abscess secondary to paradoxical emboli from pulmonary arteriovenous malformations (PAVMs) associated with HHT. Cerebral, pulmonary, hepatic and gastrointestinal involvement...
In this paper the heat signaling in microtubules (MT) is investigated. It is argued that for the description of the heat signaling phenomena in MT, the hyperbolic heat transport (HHT) equation must be used. It is shown that HHT is the Klein-Gordon (K-G) equation. The general solution for the K-G equation for MT is obtained. For the undistorted signal propagation in MT the Heisenberg uncertainty...

Hereditary hemorrhagic telangiectasia (HHT) is an autosomal dominant disorder, which is uncommon anomaly to recurrent gastrointestinal bleeding. Although there are several forms of therapy ranging from local therapy to operations or drug therapy, there is a lack of more effective treatment for the disease. In this report, we presented a Chinese patient with recurrent melena due to gastric angio...
Hereditary hemorrhagic telangiectasia (HHT; Osler-Weber-Rendu syndrome) is an uncommon disease characterized by abnormal telangiectasias and arteriovenous malformations that cause recurrent bleeding. Here, we present the case of a patient with HHT, who had a history of pulmonary and hepatic arteriovenous malformations and endocarditis of a prosthetic aortic valve that was caused by methicillin-...
The HHT (Hilbert-Huang transform) and wavelet transform are both signal processing methods. This paper is based on comparing HHT and Wavelet transform applied to Radar signals. HHT can be used for processing nonstationary and nonlinear signals. It is one of the time-frequency analysis techniques which consists of Empirical Mode Decomposition (EMD) and instantaneous frequency solution. EMD is a ...
Transient evoked otoacoustic emissions (TEOAEs) have been analyzed for objective assessment of hearing function and monitoring of the influence of noise exposure and ototoxic drugs. This paper presents a novel application of the Hilbert–Huang transform (HHT) for detection and time-frequency mapping of TEOAEs. Since the HHT does not distinguish between signal and noise, it is combined with ensem...
Rendu-Osler-Weber syndrome, or hereditary hemorrhagic teleangiectasia (HHT), is a rare autosomal dominant vascular disorder, characterized by multiple mucocutaneous teleangiectases with recurrent nasal and gastrointestinal bleedings and/or solid-organ arteriovenous shunts. We describe the first case to our knowledge of pancytopenia in a 53-year-old patient, with a known history of HHT and recur...
*Correspondence: [email protected] 2Department of Mathematics and Institute of Mathematical Research, Universiti Putra Malaysia (UPM), Serdang, Selangor 43400, Malaysia Full list of author information is available at the end of the article Abstract In this paper, we extend Hartley and Hartley-Hilbert transformations (HT and HHT, respectively) to a certain space of tempered distribution...
