This paper presents a novel approach to ECG signal filtering and classification. Unlike the traditional techniques which aim at collecting and processing the ECG signals with the patient being still, lying in bed in hospitals, our proposed algorithm is intentionally designed for monitoring and classifying the patient's ECG signals in the free-living environment. The patients are equipped with w...

we propose a new generation of unbiased (bias-free) antenna-less cw thz photomixer emitters array made of asymmetric msm gratings with subwavelength pitch, operating in optical near-field regime. we take advantage of the size effects in near-field optics and electrostatics to demonstrate the possibility of enhancing the thz power by four orders of magnitude, as compared with a similar array of ...

The development and optimization of methods for creating functional elements micron sub-micron sizes photonic integrated circuits is one the main tasks nanophotonics. Two-photon laser lithography actively developing now to form three-dimensional structures with subwave resolution. Results this are reported it shown that use optimized schemes, spatial filtering beam used, introduction dyes into ...

Automatic analysis of electrocardiograms with adequate explain-ability is a challenging task. Many deep learning based methods have been proposed for automatic classification electrocardiograms. However, very few them provide detailed explainable evidence. In our study, we explore ECG through explicit decomposition single-beat (median-beat) signal. particular, every sample decomposed into five ...

Abstract This study focuses on a condensed sequence of alternating carbonate–clastic sediments the Barrington Member, Beacon Limestone Formation (latest Pliensbachian to early Toarcian) from Somerset (SW England). Abundant ammonites confirm (apart absence Clevelandicum and Tenuicostatum ammonite subchronozones) presence Hawskerense Subchronozone Fallaciosum–Bingmanni subchronozones. Well-preser...

This special issue of Nanoscale Research Letters is a collection of selected papers presented at the Nano and Giga Challenges in Electronics, Photonics and Renewable Energy (NGC2011) conference in Moscow and Zeleno grad which addresses both theoretical and experimental achievements and provide a stimulating outlook for technological developments in these highly topical fields of research. Infor...

In this paper, a new procedure and topology of magnetic metasurface lens are proposed for improving the performance Resonant Wireless Power Transfer systems. Firstly, three subwave-length unit cells optimized in order to get negative permeability same frequency, each one with different refractive index, they experimentally characterized. Then, Transformation Optics technique is applied find cel...
