The relationship between auroral hiss at high altitudes over the polar caps and the substorm dynamics of aurora [PDF]

open access: yesAnnales Geophysicae, 2005
Strong variations of intensity and cutoff frequency of the auroral hiss were observed by INTERBALL-2 and POLAR satellites at high altitudes, poleward from the auroral oval.

The upward propagating ionospheric hiss waves during the seismic time observed by the China seismo-electromagnetic satellite

open access: yesFrontiers in Astronomy and Space Sciences, 2023
The ionospheric hiss wave is a broadband incoherent and structureless electromagnetic emission. They appear in a relatively narrower frequency range between −0.1 and 1.5 kHz. However, according to previous observations, abnormal electromagnetic emissions

State of the practice of health information systems: a survey study amongst health care professionals in intellectual disability care

open access: yesBMC Health Services Research, 2021
Background Care for people with an Intellectual Disability (ID) is complex: multiple health care professionals are involved and use different Health Information Systems (HISs) to store medical and daily care information on the same individuals.

Internal source of plasmaspheric hiss on Earth

open access: yes地球与行星物理论评, 2022
Plasmasphere is an upward extension of the ionosphere at low and middle latitudes along the closed magnetic field lines rooted in the Earth, where the trapped whistler-mode waves in the frequency range from tens to thousands of Hertz are named as ...

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

open access: yesGeophysical 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|

Analysis of plasmaspheric hiss wave amplitudes inferred from low-altitude POES electron data: Technique sensitivity analysis [PDF]

open access: yes, 2015
A novel technique capable of inferring wave amplitudes from low-altitude electron measurements from the Polar Operational Environmental Satellites (POES) spacecraft has been previously proposed to construct a global dynamic model of chorus and ...

Van Allen Probes observations linking radiation belt electrons to chorus waves during 2014 multiple storms [PDF]

open access: yes, 2015
During 18 February to 2 March 2014, the Van Allen Probes encountered multiple geomagnetic storms and simultaneously observed intensified chorus and hiss waves. During this period, there were substantial enhancements in fluxes of energetic (53.8–108.3 keV)

Randomized preclinical study of machine perfusion in vascularized composite allografts

open access: yesBJS (British Journal of Surgery), EarlyView., 2020
This study was designed to identify the optimum machine perfusion parameters for preservation of limbs before transplantation, and determine whether this was better than cold storage. Normothermic machine perfusion at a pressure of 70 mmHg (NMP‐70) provided superior preservation to cold storage after transplantation.

Disappearance of plasmaspheric hiss following interplanetary shock [PDF]

open access: yes, 2015
Plasmaspheric hiss is one of the important plasma waves controlling radiation belt dynamics. Its spatiotemporal distribution and generation mechanism are presently the object of active research.

Observations of Radiation Belt Losses Due to Cyclotron Wave-Particle Interactions [PDF]

open access: yes, 2020
Electron loss to the atmosphere plays a critical role in driving dynamics of the Earths Van Allen radiation belts and slot region. This is a review of atmospheric loss of radiation belt electrons caused by plasma wave scattering via Doppler-shifted ...
