This paper presents a novel variable step-size LMS (VSLMS) algorithm for tracking signals from the Gaussian 1/f<sup>beta</sup> family of fractal signals that are inherently nonstationary. The proposed algorithm differs from the existing VSLMS algorithms in the following ways: 1) it deals with a specific class of nonstationary signals, 2) it utilizes a(More)
This paper proposes a new method of estimating both biorthogonal compactly supported as well as semi-orthogonal infinitely/compactly supported wavelet from a given signal. The method is based on maximizing projection of the given signal onto successive scaling subspace. This results in minimization of energy of signal in the wavelet subspace. The idea used(More)
This paper presents a new approach for the estimation of wavelets that is matched to a given signal in the statistical sense. Based on this approach, a number of new methods to estimate statistically matched wavelets are proposed. The paper first proposes a new method for the estimation of statistically matched two-band compactly supported biorthogonal(More)
This paper presents novel methods for baseline wander removal and powerline interference removal from electrocardiogram (ECG) signals. Baseline wander and clean ECG have been modeled as 1st and 2nd-order fractional Brownian motion (fBm) processes, respectively. This fractal modeling is utilized to propose projection operator based approach for baseline(More)
The widespread deployment of Resource Description Framework has resulted in the emergence of a new data storage paradigm, the RDF Graph Model, which, in turn, requires a rich suite of modeling and visualization tools to aid with data management. This paper presents R2D (RDF-to-Database), an effort whose goal is to enable reusability of relational tools on(More)
Lenvatinib is an orally available multi-targeted tyrosine kinase inhibitor with anti-angiogenic and antitumor activity. To get more insight into the disposition of lenvatinib, a mass balance study was performed in patients with advanced solid tumors. A single oral 24 mg (100 μCi) dose of (14)C-lenvatinib was administered to six patients, followed by(More)
— In this paper, we propose a novel method for baseline wander removal from a noisy ECG signal. We use projection operator based approach to remove baseline wander noise from the ECG signal. The noise subspace is generated using sample functions of the first order fBm processes characterizing baseline wander noise. The orthogonal projection of noisy ECG(More)
Lenvatinib significantly prolonged progression-free survival (PFS) versus placebo in patients with radioiodine-refractory differentiated thyroid cancer (RR-DTC) in the phase 3 Study of (E7080) Lenvatinib in Differentiated Cancer of the Thyroid (SELECT) trial. This subanalysis evaluated the efficacy and safety of lenvatinib in Japanese patients who(More)
The importance of provenance information as a means to trust and validate the authenticity of available data cannot be stressed enough in today's web-enabled world. The abundance of data now accessible due to the Internet explosion brings with it the related issue of determining how much of it is trustworthy. Provenance information, such as who is(More)
