The ratio between the sea fog period and the total summer period and ship-bsead observation data

The ratio between the sea fog period and the total summer period (Rsf) We use two methods to judge the sea fog in every year, one is RH (of 1000hPa) > 95% and TD ranging within 0-2 K, the other is CBH and TP to be <100 m and <0.25 mm, respectively, the qualifying times divided by the total time, which is the Rsf-K1 and Rsf-K2 of this data set. The spatial range is 55°S~80°S,-180°~180°,See lat.txt and lon.txt for specific latitude and longitude. We calculated the average annual ratio of sea fog for a total of 41 years (1979~2019). _____ We uploaded ten years of ship-based observations, from the 30th (2013) to the 39th (2023) China Antarctic Research Expedition (CHINARE), have been taken on an ice-breaker and scientific research vessel, “Snow Dragon.”

Data from: Variations in regional white matter volumetry and microstructure during the post-adolescence period: a cross-sectional study of a cohort of 1,713 university students

Human brain white matter undergoes a protracted maturation that continues well into adulthood. Recent advances in diffusion-weighted imaging (DWI) methods allow detailed characterisations of the microstructural architecture of white matter, and they are increasingly utilised to study white matter changes during development and ageing. However, relatively little is known about the late maturational changes in the microstructural architecture of white matter during post-adolescence. Here we report on regional changes in white matter volume and microstructure in young adults undergoing university-level education. As part of the MRi-Share multi-modal brain MRI database, multi-shell, high angular resolution DWI data were acquired in a unique sample of 1,713 university students aged 18 to 26. We assessed the age and sex dependence of diffusion metrics derived from diffusion tensor imaging (DTI) and neurite orientation dispersion and density imaging (NODDI) in the white matter regions as defined itein the John Hopkins University (JHU) white matter labels atlas. We demonstrate that while regional white matter volume is relatively stable over the age range of our sample, the white matter microstructural properties show clear age-related variations. Globally, it is characterised by a robust increase in neurite density index (NDI), and to a lesser extent, orientation dispersion index (ODI). These changes are accompanied by a decrease in diffusivity. In contrast, there is minimal age-related variation in fractional anisotropy. There are regional variations in these microstructural changes: some tracts, most notably cingulum bundles, show a strong age-related increase in NDI coupled with decreases in radial and mean diffusivity, while others, mainly cortico-spinal projection tracts, primarily show an ODI increase and axial diffusivity decrease. These age-related variations are not different between males and females, but males show higher NDI and ODI and lower diffusivity than females across many tracts. These findings emphasize the complexity of changes in white matter structure occurring in this critical period of late maturation in early adulthood.

FIG. 3. — Le modèle de couverture des revues a été revu lors du passage au format A4 et à l'impression numérique (jusque-là, les périodiques étaient imprimés avec une technique d'impression offset). L'utilisation du format A4 permet de maximiser la taille des planches, une demande récurrente de la part des auteurs, qui passent ainsi à 175 mm de large au lieu des 145 mm de la précédente maquette. L'utilisation d'encres spécifiques (nuance pantone) n'étant plus possible, les couvertures durent être imprimées en quadrichromie, ouvrant de nouvelles possibilités, notamment pour les volumes thématiques. Les revues conservent bien sûr leurs couleurs respectives/The cover template for the journals was redesigned when they switched to A4 format and digital printing (until then, the periodicals were printed with in offset). The use of the A4 format allows for maximimized plate dimensions, a recurring request from the authors, now 175 mm wide instead of 145 mm in the previous format. As the use of specific inks (Pantone shades) is no longer possible, the covers are now printed in four-colour process (CMYK), opening up new possibilities, especially for thematic issues. Each journal however, has retained its respective colour.

FIG. 2. — Comparaison entre une planche tirée du troisième tome du Bulletin du Muséum d'Histoire naturelle (Pousargues 1897; voir aussi Fig. 1) et une autre tirée d'un article de Geodiversitas (Wang et al. 2009), décrivant une nouvelle espèce d'ursidé. L'utilisation d'une barre d'échelle permet le redimensionnement de la figure car sa valeur ne dépend pas de la taille d'impression, ce qui est en revanche le cas pour le rapport de taille (« ¾ gr. Nat.» sur la planche tirée du Bulletin). Le lettrage des vues (A, B, C) permet leur identification non équivoque. Si les deux spécimens sont très différents, la ressemblance entre les planches n'en est pas moins frappante/Comparison between a plate taken from vol. 3 of the Bulletin du Muséum d'Histoire naturelle (Pousargues 1897, see also Fig. 1) and another from an article by Geodiversitas (Wang et al. 2009), describing a new species of Ursidae. The use of a scale bars allow the figure to be resized as its value does not depend on the print dimensions, unlike the plate that uses a size ratio ("¾ Gr." on the plate from the Bulletin). The lettering of the views (A, B, C) allows their unambiguous identification. Despite the differences between the two specimens, the resemblance between the plates remains striking.
