Deep learning model of hiss waves in the plasmasphere and plumes and their effects on radiation belt electrons

Frontiers in Astronomy and Space Sciences, 2023
Hiss waves play an important role in removing energetic electrons from Earth’s radiation belts by precipitating them into the upper atmosphere. Compared to plasmaspheric hiss that has been studied extensively, the evolution and effects of plume hiss are ...

Statistical Investigation of the Frequency Dependence of the Chorus Source Mechanism of Plasmaspheric Hiss

Geophysical Research Letters, 2021
We use data from eight satellites to statistically examine the role of chorus as a potential source of plasmaspheric hiss. We find that the strong equatorial (|λm|

Frequency‐Dependent Responses of Plasmaspheric Hiss to the Impact of an Interplanetary Shock

Geophysical Research Letters, 2021
Plasmaspheric hiss waves are essential for the pitch‐angle scattering and precipitation of energetic electrons and interplanetary shocks may affect these waves.

Identification of Locally Generated Plasmaspheric Hiss

Geophysical Research Letters
In this study, we statistically analyze the wave properties of plasmaspheric hiss using data from the Van Allen Probes. The magnetic power spectral densities of hiss waves exhibit dependence on magnetic local time, geomagnetic activity, and the L‐shell ...

A Generation Mechanism of Banded Plasmaspheric Hiss

Geophysical Research Letters
As a unique structure of plasmaspheric hiss emissions, banded hiss waves generally consist of an upper band above ∼200 Hz, a lower band below ∼100 Hz and a power gap in between. However, the generation mechanism of banded hiss remains unclear.

The distribution of plasmaspheric hiss wave power with respect to plasmapause location

Geophysical Research Letters, 2016
In this work, Van Allen Probes data are used to derive terrestrial plasmaspheric hiss wave power distributions organized by (1) distance away from the plasmapause and (2) plasmapause distance from Earth.

Using Health Information Systems to Support Behavioral Interventions in Local Contexts: Scoping Review [PDF]

JMIR Medical Informatics
BackgroundIndividual-level behavioral interventions are designed to improve health behaviors and manage noncommunicable diseases. Neighborhood geo-referenced contexts (NGRCs) significantly impact the success of these interventions.

Long Lifetime Hiss Rays in the Disturbed Plasmasphere

Geophysical Research Letters
Plasmaspheric hiss waves are important to shape the Earth’s electron radiation belt. These waves are commonly envisioned to have a long lifetime which allows them to permeate the global plasmasphere from a spatially restricted source.

Snake-like bird hisses induce anti-predator responses in a frog [PDF]

BMC Ecology and Evolution
Some snakes emit hissing calls which are imitated by birds to deter potential predators. However, the effect of these snake and bird hisses on anuran risk recognition is not yet explored.
