The SoloHI instrument on Solar Orbiter and the WISPR instrument on Solar Probe+ will make white light coronagraphic images of the corona as the two spacecraft orbit the Sun. The minimum perihelia for Solar Orbiter is about 60 Rsun and for SP+ is 9.5 Rsun. The wide field of view of the WISPR instrument (about 105 degrees radially) corresponds to viewing the corona from 2.2 Rsun to 20 Rsun. Thus the entire Thomson hemisphere is contained within the telescope’s field and we need to think of the instrument as being a traditional remote sensing instrument and then transitioning to a local in-situ instrument. The local behavior derives from the fact that the maximum Thomson scattering will favor the electron plasma close to the spacecraft - exactly what the in-situ instruments will be sampling. SoloHI and WISPR will also observe scattered light from dust in the inner heliosphere, which will be an entirely new spatial regime for dust observations from a coronagraph, which we assume to arise from dust in the general neighborhood of about half way between the observer and the Sun. As the dust grains approach the Sun, they evaporate and do not contribute to the scattering. A dust free zone has been postulated to exist somewhere inside of 5 Rsun where all dust is evaporated, but this has never been observed. The radial position where the evaporation occurs will depend on the precise molecular composition of the individual grains. The orbital plane of Solar Orbiter will gradually increase up to about 35 degrees, enabling a very different view through the zodiacal dust cloud to test the models generated from in-ecliptic observations. In this paper we will explore some of the issues associated with the observation of the dust and will present a simple model to explore the sensitivity of the instrument to observe such evaporations.

Depuis les premières détections d'émissions aurorales par les sondes Voyager à la fin des années 70, nos connaissances des aurores de Jupiter et de Saturne ont considérablement progressé. Je présenterai ici quelques uns des derniers résultats obtenus à l'aide du télescope spatial Hubble et de la sonde Cassini en orbite autour de Saturne. Ces images acquises dans le domaine ultraviolet révèlent une complexité que l'on commence seulement à appréhender. Assemblées en séquences, elles dévoilent une dynamique surprenante. Flashs, pulsations, expansions, contractions, apparitions, disparitions, fusions, séparations et mouvements relatifs de structures étendues sur des dizaines de milliers de kilomètres ou localisés sur quelques centaines de kilomètres : la diversité des comportements que nous observons est le témoignage de la richesse des processus en œuvre dans les magnétosphères de Jupiter et Saturne. Lunes exotiques, volcans et geysers colossaux, champs magnétiques gigantesques et rotations planétaires rapides sont les ingrédients de ce surprenant laboratoire de physique des plasmas. [less ▲]

HTLV-Associated Myelopathy/Tropical Spastic Paraparesis (HAM/TSP) is a neurodegenerative disease of the central nervous system induced by Human T lymphotropic virus type 1 (HTLV-1). As a potential therapeutic approach, we previously suggested reducing the proviral load (PVL) by modulating lysine deacetylase activity using valproic acid (VPA) and exposing virus-positive cells to the host immune response. We conducted a single-center, two-year open-label trial, with 19 HAM/TSP volunteers treated with oral VPA. PVL, CD38/HLA-DR expression and CD8+ lysis efficiency were not significantly affected by VPA. Mean scores of HAM/TSP disability did not differ between baseline and final visit. Walking Time Test (WTT) increased significantly (>20%) in 3 patients and was in keeping with minor VPA side effects (drowsiness and tremor). WTT improved rapidly after VPA discontinuation. We conclude that long term treatment with VPA is safe in HAM/TSP. [less ▲]

This communication deals with the question to know if this is possible to program a neural system with a language and a consciousness. There are several levels and categories of language, by example, verbal and non-verbal languages, signs language, etc. There are also several levels and categories of consciousness, by example, verbal consciousness, non-verbal selfconsciousness, and absence of consciousness with the a-consciousness. By a systemic approach, we extend the role of the brain to the whole neural ectoderm, including the nervous systems, the brainstem, the brain, and the skin that is the actual envelope of the brain to the environment. This paper will demonstrate that such a neural system can be programmed, on the basis of scientific research in experimental neurosciences and in artificial intelligence, extending de facto all the possibilities of learning of classical neural networks.
