Off-equatorial effects of the nonlinear interaction of VLF chorus waves with radiation belt electrons

Frontiers in Astronomy and Space Sciences, 2022
Nonlinear processes are involved in both the growth of VLF chorus waves and the energization of radiation belt electrons trapped in the wave potential. Nonlinear theory has led to analytic formulae describing both these processes.

The Spectrum of Abnormal Tongue Movements: Review of Phenomenology, Etiology, and Differential Diagnosis

Movement Disorders Clinical Practice, EarlyView.
ABSTRACT Background Classifying abnormal tongue movements is challenging due to their varied presentations and limited visibility compared to other body parts. Accurate identification of the phenomenology guides physical examination and can point to specific diagnoses.

Large-scale magnetic field oscillations and their effects on modulating energetic electron precipitation

Frontiers in Astronomy and Space Sciences
In this study, we present simultaneous multi-point observations of magnetospheric oscillations on a time scale of tens of minutes (forced-breathing mode) and modulated whistler-mode chorus waves, associated with concurrent energetic electron ...

What drives chorus wave frequency chirping?

Physics of Plasmas
For over 50 years, chorus wave frequency chirping has been regarded as a nonlinear phenomenon driven by the hot electron current density aligned with the wave magnetic field (δjB). However, recent theoretical models have challenged the crucial role played by δjB.

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

Inferring Whistler‐Mode Chorus Wave Source Regions in the Martian Mini‐Magnetospheres

Geophysical Research Letters
Martian mini‐magnetospheres contain whistler‐mode chorus waves potentially contributing to atmospheric escape, analogous to the Earth's inner magnetosphere.

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 ...

Unraveling the Role of Electron Plateau Distributions in the Power Gap Formation of Chorus Waves: Van Allen Probes Observations

Geophysical Research Letters, 2023
The power gap of chorus waves at ∼0.5fce has been discovered for decades, but its generation mechanism is still under debate. Previous studies have revealed that electron plateau distributions are vitally important for the gap formation.

Gender‐Sensitive Resilience in Kyrgyz Households: Latent Profile and Cross‐Lagged Dynamic Panel Approaches

Australian Journal of Agricultural and Resource Economics, EarlyView.
ABSTRACT Resilience is still conceptualised as gender‐neutral in research and policy discussions. However, a gendered resilience framework suggests that gender roles and intra‐household dynamics are intricately linked with household resilience. This manuscript aims to analyse the effect of gender role attitudes on climate change resilience.

Simulation of Downward Frequency Chirping in the Rising Tone Chorus Element

Geophysical Research Letters, 2023
The frequency chirping of chorus waves is commonly observed in the Earth’s inner magnetosphere, but its generation remains an open question. Recently, Liu et al.
