Burst occurrence in young massive stellar objects [PDF]
, 2018 Episodic accretion-driven outbursts are an extreme manifestation of accretion variability. It has been proposed that the development of gravitational instabilities in the proto-circumstellar medium of massive young stellar objects (MYSOs) can lead to such luminous bursts, when clumps of fragmented accretion discs migrate onto the star.

Recent enrichment of megafauna in the north of Eurasia supports the concept of Pleistocene rewilding
Wildlife Biology, EarlyView.‘Pleistocene rewilding' refers to the concept of restoring ecosystems to their state during the Pleistocene epoch, by (re‐)introducing species or their close relatives that were present during that time, in an effort to revive ecological processes that existed before human‐driven extinctions.

On Pansiot Words Avoiding 3-Repetitions [PDF]
EPTCS 63, 2011, pp. 138-146, 2011 The recently confirmed Dejean's conjecture about the threshold between avoidable and unavoidable powers of words gave rise to interesting and challenging problems on the structure and growth of threshold words. Over any finite alphabet with k >= 5 letters, Pansiot words avoiding 3-repetitions form a regular language, which is a rather small superset of

Evaluating Transferability of BERT Models on Uralic Languages [PDF]
arXiv, 2021 Transformer-based language models such as BERT have outperformed previous models on a large number of English benchmarks, but their evaluation is often limited to English or a small number of well-resourced languages. In this work, we evaluate monolingual, multilingual, and randomly initialized language models from the BERT family on a variety of ...
