Revisiting the solar wind structures contributing crucially to the main phase of the major geomagnetic storms in May 1997

Terrestrial, Atmospheric and Oceanic Sciences
We re-examined the contributions of the sheath region and the magnetic cloud to the main phase of the major geomagnetic storm on May 15, 1997. Our analysis revealed that the maximum values of the southward component of the interplanetary magnetic field ...

Response of the mid-latitude atmosphere to sporadic cosmic ray variations in the western Siberian region

Solar-Terrestrial Physics
We have analyzed spatial and temporal variations in ionospheric parameters over high and middle latitudes of Eurasia, using data from chains of high- and mid-latitude ionosondes during a severe magnetic storm in March 2015.

IONOSPHERIC STORM OF AUGUST 5–6, 2011: CALCULATION OF MAIN EFFECTS

Radio Physics and Radio Astronomy, 2014
Calculation of dynamic and thermal processes parameters during the severe magnetic storm of August 5–6, 2011 (Kp max=8−) are presented. The magnetic storm was accompanied by negative ionospheric disturbance over Kharkiv which caused a number of changes ...

Genetically Programmed Shape‐Morphing of Engineered Living Materials

Advanced Functional Materials, EarlyView.
Here, bacterial and mammalian engineered living materials (ELMs) are presented, in which living cells direct genetically programmed and enzymatically mediated shape‐morphing. The resulting deformation and shape‐recovery can be actuated in a genetically controlled manner by an ELM incorporating out‐of‐equilibrium counteracting biochemical reactions with

The Magnetic Storms [PDF]

Nature, 1882
THE magnetographs at the Kew Observatory were a little disturbed from about 11 p.m. of the 13th inst. to 7 p.m. of the 14th inst. During the 15th they were quiet, and remained so up to 11.45 p.m. of the 16th, when the disturbance began by an increase of the declination, an augmentation of the horizontal force, and a diminution of the vertical force ...

Quantification of Phosphorylated Tau Protein in Alzheimer's Disease Patients’ Fluids With Electrolyte‐Gated Organic Transistor Biosensors

Advanced Healthcare Materials, EarlyView.
Dementia syndrome affects millions of people in the world, and Alzheimer's disease (AD) is the most common cause. We report the detection of the specific biomarker for AD, p‐tau‐181, from physiological to pathological concentrations in cerebrospinal fluid using an electrolyte‐gated organic transistor biosensor.

Ring current and auroral electrojets in connection with interplanetary medium parameters during magnetic storm [PDF]

Annales Geophysicae, 1994
The relationship between the auroral electrojet indices (AE) and the ring current magnetic field (DR) was investigated by observations obtained during the magnetic storm on 1-3 April 1973.

Universal Conductance Fluctuations in Quantum Anomalous Hall Insulators

Advanced Materials, EarlyView.
Universal conductance fluctuations are observed in mesoscopic quantum anomalous Hall insulators. Two distinct fluctuation patterns are identified, arising from different interference processes of bulk and chiral edge states, respectively. These findings unveil rich quantum interference phenomena in quantum anomalous Hall insulators and provide insights

A statistical comparison of hot-ion properties at geosynchronous orbit during intense and moderate geomagnetic storms at solar maximum and minimum. [PDF]

, 2006
Hot-ion measurements at geosynchronous orbit from the Los Alamos Magnetospheric Plasma Analyzer (MPA) instrument during geomagnetic storms at solar maximum (July 1999–June 2002) and at solar minimum (July 1994–June 1997) are collected, categorized, and ...
