Detection of the warning signals by the heart can be diagnosed from ECG.An accurate and reliable diagnosis of ECG is very important however which is cumbersome and at times ambiguous in time domain due to the presence of noise.Study of ECG in wavelet domain using both continuous Wavelet transform (CWT) and discrete Wavelet transform 100w products (

Abstract Gradient matters with hierarchical structures endow the natural world with excellent integrity and diversity.Currently, direct ink writing 3D printing is attracting tremendous interest, and has been used to explore the here fabrication of 1D and 2D hierarchical structures by adjusting the diameter, spacing, and angle between filaments.Howe

A thick-hard roof implies a large hanging-roof and high-frequency dynamic strata behaviour during mining, which may jeopardise personnel safety and equipment.To alleviate these hazards, deep-hole pre-splitting blasting is employed to control periodic fractures in thick-hard roof seams in Datong mining area.Based on loading and instability character

Evidence for the production, use, and control of fire by Neanderthals in Europe ranges from the scale of ecosystems to microscopic alterations of artefacts.While there is a consensus that Neanderthals were skilled in the use of fire, there remains a dispute over whether they had mastered the ability to produce fire on demand.The unique discovery th
