The JJI VLF (22.2 kHz) transmitter signal received at two low-latitude stations, one in Port Vila (geog. coord., 17.73°S, 168.33°E), Vanuatu and other Suva (18.14°S, 178.44°E), Fiji, was analyzed for any changes due to 16 Earthquakes (EQs) with magnitudes 5.5 7.7, during 2018 (JJI-Vanuatu path, 6.8 Mm) 2007 (JJI-Suva 7.5 Mm). amplitude analysis included terminator time (TT), average daytime nig...

Fig. 1. Omnidirectional energy spectrum E(k) versus wavenumber k, computed from Eqs. (9)-(11), for the case A = 0:7, = 1, varying the rotation rate = 0; 10; 100. There is a smooth transition from the Komogorov`? 5=3' case = 0 to a spectrum = 100 that approaches a ` ? 2' form. Spontaneous breaking of reeexional symmetry in real quasi-two-dimensional turbulence: stochastic traveling waves and hel...

– Theoretical studies suggest that the final earthquake (EQ) and neural-seizure dynamics should have many similar features and could be analyzed within similar mathematical frameworks. Herein, by monitoring the temporal evolution of the fractal spectral characteristics in EEG time series and pre-seismic electromagnetic (EM) time series we show that many similar distinctive symptoms (including c...

Whether electromagnetic precursors to earthquakes (EQs) exist is an important question not only for EQ prediction but also for understanding the physical processes of EQ generation. Slow transient geoelectric potential changes have been observed before several recent EQs in Japan. In most cases, they appeared 1-19 days before the EQs, and their duration and intensity were several minutes to 1 h...

Critical limitations of the waveform relaxation method concern the unsolved problems of estimating convergence and controlling the iteration. In this paper, waveform relaxation is applied to a linear, second-order model system and is studied in the Laplace domain. By placing the iteration in a weighted space, computable estimates for a window of rapid convergence are developed. Numerical experi...

Polarizabilities, dispersion coefficients, and long-range atom-surface interaction potentials are calculated for the n = 2 triplet and singlet states of helium using highly accurate, variationally determined, wave functions. PACS numbers: 34.20.Cf, 32.10.Dk, 34.50.Dy Typeset using REVTEX 1 The advent of doubled basis sets has made it possible to calculate precisely many properties of two-electr...
