A Review of Geomagnetically Induced Current Effects on Electrical Power System: Principles and Theory

IEEE Access, 2020
Geomagnetically induced current (GIC) has been a significant concern for the electrical power grid in high latitudes for decades. Its origin starts in the Sun; during extreme space weather, the magnetic field of the Earth varies rapidly.

Deglaciation of the Burren glacio‐karst, western Ireland, during Termination 1: Implications for North Atlantic climate and karstification

Journal of Quaternary Science, EarlyView.
Abstract The Burren uplands in western Ireland form one of the most extensive and best‐preserved examples of glacio‐karst in Europe. Subsumed by the Irish ice sheet during the Late Pleistocene, granite erratic boulders and in situ silica veins in the limestone bedrock provide a rare opportunity to reconstruct the timing and rate of deglaciation ...

The First Archaeomagnetic Age at Tiwanaku and Implications for Dating Andean Metallurgical Furnaces

Archaeometry, EarlyView.
ABSTRACT This paper presents the first archaeomagnetic dating at Tiwanaku (Andean Altiplano). We compared the geomagnetic field values recorded by a metallurgical furnace against an updated SHAWQ2k‐SH global model and a regional intensity curve, both of which include, for the first time, high‐quality intensity data from the Southern Hemisphere.

A supramolecular assembly of cone‐specific G‐protein and cryptochrome 4a on lipid bilayer

The FEBS Journal, EarlyView.
Immobilized phospholipid bilayers on a sensor chip surface serve as membrane platform to investigate critical protein–lipid and protein–protein interaction processes by surface plasmon resonance. The putative magnetoreceptor cryptochrome 4a and the myristoylated cone‐specific G‐protein α‐subunit (Gtα) bind with high affinity to immobilized lipid ...
