We discuss the nature of the circumstellar envelopes around the B[e] supergiants (B[e]SG) in the Magellanic Clouds (MC). Contrary to those in the Galaxy, the MC B[e]SG have a well defined luminosity and can be considered members of a well defined class. We discuss spectroscopy and optical broadband polarimetry and spectropolarimetry data. These data show for the first time detailed changes in t...

This paper summarizes the evidence of the ultraviolet properties of dust grains found in starburst galaxies. Observations of starburst galaxies clearly show that the 2175 Å feature is weak or absent. This can be the result of radiative transfer effects (mixing the dust and stars) or due to dust grains which do not have this feature. Spherical DIRTY radiative transfer models imply that it is not...

Masked autoencoding has achieved great success for self-supervised learning in the image and language domains. However, mask based pretraining yet to show benefits point cloud understanding, likely due standard backbones like PointNet being unable properly handle training versus testing distribution mismatch introduced by masking during training. In this paper, we bridge gap proposing a discrim...

conclusions the findings of this study indicate that the frequency of disfluencies was increased in difficult syllable structures in comparison to simple syllable structures. according to the results, it seems that certain linguistic features, such as syllable structure can affect speech-motor output in people who stutter through affecting phonological encoding. background stuttering is one of ...

Project management has incorporated sustainability concepts, but their relationship is still widely discussed. In this article, we research key practices for incorporating in project from the perspective of 919 Brazilian professionals with experience field. We used factor analysis to explore between 37 practices. The results showed that these can be grouped into five practices: environmental ef...

The relationship between cinema and literature is permanent from film’s beginnings, with film adaptations stealing fire great works. This paper analyses the tourism, focusing on role of Brazilian literature’s influences in this context. Storytelling as a tool relevance “travel purpose” are additional subjects discussed relation to type tourism. an exploratory study that uses textual analysis (w...

The subject of the article are words from first volume Most Królowej Jadwigi by Jerzy Sulima-Kamiński (nouns, e.g. półmieszczuch [‘half-townsperson’], verbs, powiecować [‘attend mass meetings’], adverbs, such as glistowato [‘like a worm’] and tłusto in oil’]), probable loan word German merble (the name fruit mealy rowan), absent general Polish dictionaries. Some these can be considered to artis...

Stratocumulus clouds (Sc) have a significant impact on the amount of sunlight reflected back to space, with important implications for Earth's climate. Representing Sc and their radiative impact is one of the largest challenges for global climate models. Sc fields self-organize into cellular patterns and thus lend themselves to analysis and quantification in terms of natural cellular networks. ...
