Anomalous effect in Schumann resonance phenomena observed in Japan, possibly associated with the Chi-chi earthquake in Taiwan [PDF]

Annales Geophysicae, 2005
The Schumann resonance phenomenon has been monitored at Nakatsugawa (near Nagoya) in Japan since the beginning of 1999, and due to the occurance of a severe earthquake (so-called Chi-chi earthquake) on 21 September 1999 in Taiwan we have examined our ...

Influence of Magnetic Field with Schumann Resonance Frequencies on Photosynthetic Light Reactions in Wheat and Pea [PDF]

Cells, 2021
Photosynthesis is an important target of action of numerous environmental factors; in particular, stressors can strongly affect photosynthetic light reactions.

The effect of a gamma ray flare on Schumann resonances [PDF]

Annales Geophysicae, 2012
We describe the ionospheric modification by the SGR 1806-20 gamma flare (27 December 2004) seen in the global electromagnetic (Schumann) resonance. The gamma rays lowered the ionosphere over the dayside of the globe and modified the Schumann resonance

Response of photosynthesis and electrical reactions of wheat plants upon the action of magnetic fields in the Schumann resonance frequency band [PDF]

Plant Signaling & Behavior
Alternating magnetic fields (MF) with Schumann resonance frequencies accompanied the development of living organisms throughout evolution, but today it remains unclear whether they can have a special biological effect in comparison with surrounding non ...

Universal and local time components in Schumann resonance intensity [PDF]

Annales Geophysicae, 2008
We extend the technique suggested by Sentman and Fraser (1991) and discussed by Pechony and Price (2006), the technique for separating the local and universal time variations in the Schumann resonance intensity.

Similar Spectral Power Densities Within the Schumann Resonance and a Large Population of Quantitative Electroencephalographic Profiles: Supportive Evidence for Koenig and Pobachenko. [PDF]

PLoS ONE, 2016
In 1954 and 1960 Koenig and his colleagues described the remarkable similarities of spectral power density profiles and patterns between the earth-ionosphere resonance and human brain activity which also share magnitudes for both electric field (mV/m ...

SCHUMANN RESONANCE BACKGROUND SIGNAL SYNTHESIZED IN TIME [PDF]

Радиофизика и электроника, 2017
Simulation of signals of the global electromagnetic reso-nance is of great interest in theory and the measurement practice. We describe a method of generating the artificial Schumann resonance signal and present its major features.

Hippocampal vascularization is associated with greater efficiency during a remote real world wayfinding training in older adults [PDF]

Alzheimers Dement
Abstract Background Alzheimer's Disease (AD) pathology accumulates early in the medial temporal lobe (MTL), crucial for spatial navigation. As spatial navigation is among the first cognitive functions affected by AD, it may benefit from targeted behavioral interventions. We investigated the potential of a novel smartphone‐assisted real‐world wayfinding

Homoterpene Biosynthesis in Fungi. [PDF]

Angew Chem Int Ed Engl
The first homoterpene biosynthetic pathway in the fungal kingdom is reported. A methyltransferase–terpene cyclase pair produces a unique heptamethyl bicyclo[3.3.1]nonane homoterpene via presodorifen, demonstrating that homoterpene biosynthesis via the addition of a C1 unit to terpene diphosphate precursors prior to scaffold formation extends beyond the

Functional Connectivity Within the Central Autonomic Network Increases During Resonance Paced Breathing at 0.1 Hz. [PDF]

Psychophysiology
ABSTRACT Physiological processes such as respiration, while typically automatic, can be brought under volitional control to initiate cascading effects across the autonomic and central nervous systems. Slow breathing paced at approximately six breaths‐per‐minute, termed resonance paced breathing (RPB), activates the 0.1 Hz resonance frequency of the ...
