Randomized preclinical study of machine perfusion in vascularized composite allografts

BJS (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.

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|

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

Frontiers 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

The Study on Modeling of Global Plasmaspheric Hiss Amplitude Based on Deep Learning Algorithm

Space Weather, 2023
Plasmaspheric hiss waves make great significance on the loss of electrons in the Earth's radiation belts. The prediction and reconstruction for global evolution plasmaspheric hiss are critical to investigate the dynamic process of radiation belt. In this

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

Annales 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 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.

Hot plasma effects on the dispersion properties of plasmaspheric hiss and its electron diffusion

地球与行星物理论评, 2023
Electron diffusion caused by plasmaspheric hiss is an important mechanism for the loss of electrons in Earth's inner magnetosphere; it has also been considered responsible for the formation of the slot region between inner and outer radiation belts.

The Evolution of Whistler Hiss‐Like Waves Across Plasmapause: Hiss to Exohiss

Geophysical Research Letters, 2023
The exohiss waves are hiss‐like whistler mode waves that occur outside plasmapause. Although these waves can cause the loss of radiation belt electrons ∼

Arrival direction finding for narrow-band auroral hiss at Syowa Station

Antarctic Record, 1982
From the direction finding (DF) observations based on the measurement of wave arrival time differences among three spaced points around Syowa Station (geomagnetic lat. -70.0°), the arrival direction of narrow-band auroral hiss was examined.
