Pulsed Electromagnetic Fields: A Novel Attractive Therapeutic Opportunity for Neuroprotection After Acute Cerebral Ischemia

Neuromodulation: Technology at the Neural Interface, EarlyView., 2021
Abstract Objectives Acute cerebral ischemia is characterized by several pathological processes evolving during time, which contribute to the final tissue damage. Secondary processes, such as prolonged inflammatory response, impaired mitochondrial function and oxidative stress, are responsible for the progression of brain injury to the peri‐infarct area,

First Results of the THEMIS Search Coil Magnetometers [PDF]

Space Science Reviews, 2008
We present the first data from the THEMIS Search Coil Magnetometers (SCM), taken between March and June 2007 while the THEMIS constellation apogee moved from the duskside toward the dawnside. Data reduction, especially the SCM calibration method and spurious noise reduction process, is described.

Diurnal behaviour of the ionospheric Alfvén resonator signatures as observed at high latitude observatory Barentsburg (L=15) [PDF]

Annales Geophysicae, 2008
The signature of the ionospheric Alfvén resonator (IAR), so called spectral resonant structures (SRS) in the spectra of the electromagnetic noise in the range of 0.1–10 Hz is rather frequently observed with the search coil magnetometer at observatory ...

A calibration facility for search coil magnetometers [PDF]

Measurement Science and Technology, 2002
A calibration facility for search coil magnetometers (SCMs) has been built at Niemegk Geomagnetic Observatory, GeoForschungsZentrum Potsdam. I describe here the commissioning of this facility. The usable frequency range of 10 mHz-100 kHz enables calibration of all standard types of SCM.

A Low-cost Electromagnetic Docking Guidance System for Micro Autonomous Underwater Vehicles

Sensors, 2019
As important observational platforms for the Smart Ocean concept, autonomous underwater vehicles (AUVs) that perform long-term observation in fleets are beneficial because they provide large-scale sampling data with a sufficient spatiotemporal resolution.

Optimized merging of search coil and fluxgate data for MMS [PDF]

Geoscientific Instrumentation, Methods and Data Systems, 2016
The Magnetospheric Multiscale mission (MMS) targets the characterization of fine-scale current structures in the Earth's tail and magnetopause. The high speed of these structures, when traversing one of the MMS spacecraft, creates magnetic field ...
