Modeling Schumann resonances with schupy [PDF]

Journal of Atmospheric and Solar-Terrestrial Physics, 2019
Abstract Schupy is an open-source python package aimed at modeling and analyzing Schumann resonances (SRs), the global electromagnetic resonances of the Earth-ionosphere cavity resonator in the lowest part of the extremely low frequency band ( 100 Hz).

A new portable ELF Schumann resonance receiver: design and detailed analysis of the antenna and the analog front-end

EURASIP Journal on Wireless Communications and Networking, 2018
Schumann resonance oscillation detection is a complex procedure which requires customized and high-quality measurement systems. The primary objective of this work was to design and implement a stand-alone, portable, and low-cost receiver able to measure ...

Gigantism in unique biogenic magnetite at the Paleocene-Eocene Thermal Maximum [PDF]

, 2008
We report the discovery of exceptionally large biogenic magnetite crystals in clay-rich sediments spanning the Paleocene-Eocene Thermal Maximum (PETM) in a borehole at Ancora, New Jersey. Aside from previously-described abundant bacterial magnetofossils,

Psychotic-Like Experiences and White Matter Microstructure: A Fixel-Based Analysis Approach With Robust Replication Across Two Cohorts. [PDF]

Hum Brain Mapp
We used Fixel‐Based Analysis (FBA) to investigate the relationship between psychotic‐like experiences and white matter microstructure across two independent cohorts of healthy participants (Study 1: n = 41; Study 2: n = 1098). Contrary to our hypothesis, we found no significant correlation between FBA metrics of white matter microstructure and ...

Constraining scalar resonances with top-quark pair production at the LHC [PDF]

, 2017
Constraints on models which predict resonant top-quark pair production at the LHC are provided via a reinterpretation of the Standard Model (SM) particle level measurement of the top-anti-top invariant mass distribution, $m(t\bar{t})$.

Correlated noise in networks of gravitational-wave detectors: subtraction and mitigation [PDF]

, 2014
One of the key science goals of advanced gravitational-wave detectors is to observe a stochastic gravitational-wave background. However, recent work demonstrates that correlated magnetic fields from Schumann resonances can produce correlated strain noise

Model modifications in Schumann resonance intensity caused by a localized ionosphere disturbance over the earthquake epicenter [PDF]

Annales Geophysicae, 2006
This paper is a further extension of our latest observations and modeling by Hayakawa et al. (2005a), in which we discovered the anomalous behavior of Schumann resonance observed in Japan, in possible association with the Chi-chi earthquake in ...

SHIFT OF ANTIPODE MAXIMUM OF ELECTRIC FIELD IN THE RESONATOR THE EARTH–IONOSPHERE CAVITY CAUSED BY DAY–NIGHT NON-UNIFORMITY [PDF]

Радиофизика и электроника, 2017
Accounting for the actual structure of the lower ionosphere in the problems of global electromagnetic (Schumann) resonance is an important and urgent task.
