Field-aligned chorus wave spectral power in Earth's outer radiation belt [PDF]

Annales Geophysicae, 2015
Chorus-type whistler waves are one of the most intense electromagnetic waves generated naturally in the magnetosphere. These waves have a substantial impact on the radiation belt dynamics as they are thought to contribute to electron acceleration and ...

Propagation of Chorus Waves Generated in Minimum‐B Pockets

Geophysical Research Letters, 2021
AbstractWe present the first ray tracing results of chorus waves generated in minimum‐B pockets. A new ray tracer is developed to accommodate an arbitrary magnetic field model, which enables us to construct minimum‐B pocket geometries using the Tsyganenko (1989) model.

Clinical Utility of Nuchal Translucency Measurement in First‐Trimester Ultrasound Screening in a Setting With First‐Tier NIPT for Aneuploidy Screening

Prenatal Diagnosis, EarlyView.
ABSTRACT Objective To investigate the additional clinical value of nuchal translucency (NT) measurement at the first‐trimester anomaly scan (FTAS) in a setting with first‐tier non‐invasive prenatal testing (NIPT). Method This nationwide prospective cohort study, part of the IMITAS study on FTAS implementation, included all pregnancies with increased NT

Association of Relativistic Electron Microbursts Duration With Chorus Wave Properties

Geophysical Research Letters
Relativistic electron microbursts are correlated with resonant scattering by whistler‐mode chorus waves. Here, we use chorus wave properties obtained from Van Allen Probe A to calculate the duration of relativistic microbursts.

Survey of ELF-VLF plasma waves in outer radiation belt observed by Cluster STAFF-SA experiment [PDF]

Annales Geophysicae, 2008
Various types of plasma waves have profound effects on acceleration and scattering of radiation belt particles. For the purposes of radiation belt modeling it is necessary to know statistical distributions of plasma wave parameters.

Proton aurora and relativistic electron microbursts scattered by electromagnetic ion cyclotron waves

Frontiers in Astronomy and Space Sciences, 2022
Charged particle precipitation from Earth’s magnetosphere results in stunning displays of the aurora and energy transfer into the atmosphere. Some of this precipitation is caused by wave-particle interactions.

Structural Variation Sequencing of 26 Amniotic Fluid Samples With Partial Gene Duplications and Postnatal Follow‐Up of the Fetuses

Prenatal Diagnosis, EarlyView.
ABSTRACT Objectives Partial gene duplications (PGDups) are a significant contributor to genetic disease. The precise genomic location and structure of PGDups are often unresolved using conventional methods, so prenatal diagnosis for PGDups is challenging, especially without ultrasound abnormalities.

Doorwerken met reuma : stel persoon centraal, niet de ziekte [PDF]

, 2005
In Nederland kampen naar schatting 200.000 mensen in de arbeidzame leeftijd met een chronische reumatische aandoening. Een aanzienlijk deel van hen stopt op zeker moment onvrijwillig met werken.

Sonified Signals From a Compact FT‐ICR Instrument: A Feasibility Study. I—Data Mapping to an Equal‐Tempered Chromatic Scale

Rapid Communications in Mass Spectrometry, EarlyView.
ABSTRACT Rationale Ions trapped within a Penning cell (ICR) travel periodic orbits whose frequencies are dependent on their mass‐to‐charge ratio and the value of the magnetic field passing through the trap. Fourier transformation (FT‐ICR) decomposes the signal induced in the detection circuit by the rotation of the ions in the cell after the ...

Widespread Bomb Fishing in Indo‐Pacific Archipelago Revealed Through Machine Learning Accelerated Passive Acoustic Monitoring

Remote Sensing in Ecology and Conservation, EarlyView.
AI‐accelerated passive acoustic monitoring reveals extensive bomb fishing within the Spermonde Archipelago, with annual incidents numbering in the thousands. ABSTRACT Bomb fishing is recognised as the most destructive fishing practice that can be performed in our oceans.
