Source parameters of the M 6.5 Skyros Island (North Aegean Sea) earthquake of July 26, 2001

Annals of Geophysics, 2002
Teleseismic body wave modelling, time domain moment tensor inversion of regional waveforms and spectral analysis of the far-field P-wave pulses are used to derive the source parameters of the July 26, 2001 Skyros earthquake (M 6.5).

The landslide velocity [PDF]

Earth Surface Dynamics, 2022
Proper knowledge of velocity is required in accurately determining the enormous destructive energy carried by a landslide. We present the first, simple and physics-based general analytical landslide velocity model that simultaneously incorporates the ...

Atrial electromechanical delay, neutrophil-to-lymphocyte ratio, and echocardiographic changes in patients with acute and stable chronic obstructive pulmonary disease

Journal of Research in Medical Sciences, 2022
Background: Atrial electromechanical delay (AEMD) is the time interval between the beginning of P wave on surface electrocardiography and starting of the late diastolic wave on tissue Doppler imaging.

MOESM1 of P-wave first-motion polarity determination of waveform data in western Japan using deep learning

, 2019
Additional file 1: Fig. S1. Polarity plots on maps. Polarities determined by the CNN models and human experts are plotted on a map. Black and white circles represent match examples, which denote Up and Down, respectively. Dark blue and light blue circles represent mismatch examples. Dark (Light) blue means that the decision by human experts is Up (Down)

On the hydrostatic approximation in rotating stratified flow [PDF]

Nonlinear Processes in Geophysics
Hydrostatic models were and still are the workhorses for realistic simulations of ocean dynamics, especially for climate applications. Introducing a Fourier space projection method and using the Heisenberg–Gabor limit, a formalism is developed to ...
