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.

Introducing Diradicaloid Thiele's Hydrocarbon Derivatives as Ligand in Transition Metal Chemistry

open access: yesAngewandte Chemie, EarlyView.
N‐doped Thiele's hydrocarbon derivative is introduced as a ligand for the synthesis of mono‐ and bimetallic rhodium complexes as well as cyclometalated iridium complexes. These compounds constitute the first metal complexes based on a Thiele's hydrocarbon (or p‐quinodimethane) derivative and, to the best of our knowledge, the first cyclometalated ...

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

open access: yesAntarctic 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.

Fluctuation of Lower Ionosphere Associated with Energetic Electron Precipitations during a Substorm

open access: yesAtmosphere, 2021
In this paper, using the combined observations of the NOAA 16, LANL-01A, IMAGE satellites, VLF radio wave, and ground-based riometers, we study the fluctuation of lower ionosphere-associated precipitating energetic electrons during a geomagnetic storm on

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

open access: yes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.

Mobile robot visual homing by vector pre-assigned mechanism [PDF]

open access: yesBulletin of the Polish Academy of Sciences: Technical Sciences, 2019
In this paper, we present an optimization mechanism for two popular landmark-based mobile robot visual homing algorithms (ALV and HiSS), called vector pre-assigned mechanism (VPM).

When Poor Exciton Dissociation Limits Photocurrents in Organic Solar Cells: Why Low Offset Non‐Fullerene Acceptor Blends Can't Be Efficient

open access: yesAdvanced Materials, EarlyView.
The energetic offset between the donor and the acceptor components in organic photoactive layers is central to the tradeoff between photovoltage and photocurrent losses. This Perspective covers the most important issues surrounding this topic in non‐fullerene acceptor blends, from the difficulty of accurately determining state energies and driving ...

Comparisons of Auroral Hiss Spectra Observed at Syowa and Mizuho Stations (c. Wave-Particle Interactions in the Magnetosphere) (Proceedings of the Second Symposium on Coordinated Observations of the Ionosphere and Magnetosphere in the Polar Regions : Part I)

open access: yesAntarctic Record, 1980
Simultaneous observations of auroral hiss emissions have been carried out at Syowa and Mizuho Stations. The intensity of auroral hiss emissions was different from case by case at the two stations. However the spectral shapes of hiss emissions obtained at
