Calibration of multi-layered probes with low/high magnetic moments

open access: yesScientific Reports, 2017
We present a comprehensive method for visualisation and quantification of the magnetic stray field of magnetic force microscopy (MFM) probes, applied to the particular case of custom-made multi-layered probes with controllable high/low magnetic moment ...

Mutual Impedance Probe in Collisionless Unmagnetized Plasmas With Suprathermal Electrons—Application to BepiColombo

open access: yesFrontiers in Astronomy and Space Sciences, 2019
Context: Mutual impedance experiments are active electric probes providing in-situ space plasma measurements. Such active experiments consist of a set of electric antennas used as transmitter(s) and receivers(s) through which various dielectric ...

Measurement of Electron Density and Temperature by Means of Contamination-Free Probe

open access: yesAntarctic Record, 1975
In plasma diagnosis by means of a Langmuir probe, contamination of the electrode is a quite serious problem. In order to get reliable data of space plasma, cleaning of the electrode is an essential requirement.

The Cosmic Timeline of Heliophysics: A Declaration of Significance

open access: yesPerspectives of Earth and Space Scientists, 2020
Key Points The domain of Heliophysics, within the heliosphere, is complementary to the domain of Astrophysics, but can be studied directly by in situ probes The domain of Heliophysics is uniquely distinguished from that of Astrophysics by the presence of

Probing Into Space-Time View [PDF]

open access: yes, 2020
Space-time view is the cornerstone of physics, which can be divided into two categories. One is the absolute space-time view, it is a description of pure and real space-time. Because there is no a space with nothing, the absolute space-time view will deviate from the actual measured value quantitatively.

Intracristal space proteome mapping using super-resolution proximity labeling with isotope-coded probes

open access: yesNature Communications
Proximity labeling with engineered ascorbate peroxidase (APEX) has been widely used to identify proteomes within various membrane-enclosed subcellular organelles. However, constructing protein distribution maps between two non-partitioned proximal spaces

Evidence of Microbursts Observed Near the Equatorial Plane in the Outer Van Allen Radiation Belt

open access: yesGeophysical Research Letters, 2018
We present the first evidence of electron microbursts observed near the equatorial plane in Earth's outer radiation belt. We observed the microbursts on 31 March 2017 with the Magnetic Electron Ion Spectrometer and Radiation Belt Storm Probes Ion ...

PROBES, POPULATIONS, SAMPLES, MEASUREMENTS AND RELATIONS IN STEREOLOGY

open access: yesImage Analysis and Stereology, 2011
This summary paper provides an overview of the content of stereology. The typical problem at hand centers around some three dimensional object that has an internal structure that determines its function, performance, or response.
