On the flora of honey plants of the Northern and Northwestern Altai regions within the Altai Territory [PDF]
BIO Web of Conferences, 2019 The revision of honey plants in the regions’ floras and nature objects is regularly made for estimation of melliferous capacity of the territory. The article is devoted to the investigation of the melliferous flora of Northern and North-Western Altai in the area of Altai Territory.

Journal of Systematics and Evolution, EarlyView.Phylogenetic relationships within Koeleriinae clades A and B are examined using DNA sequences of plastid rpl32‐trnL, rps16‐trnK, rps16 intron, and ITS regions. Phylogenetic analyses of different selected data sets yielded mostly congruent topologies in nuclear and plastid trees.

A non-singular universe with vacuum energy [PDF]
Int.J.Theor.Phys.50:3521-3528,2011, 2009 We construct a model for the universe based on the existence of quantum fields at finite temperature in the background of Robertson-Walker spacetime in presence of a non-zero cosmological constant. We discuss the vacuum regime in the light of the results obtained through previous studies of the back-reaction of massless quantum fields in the static ...

Transactions of the Institute of British Geographers, EarlyView.Abstract This paper explores the heterogeneity of migrant visibility across space and time, analysing where and how Eritrean forced migrants travelling along the Central Mediterranean Route are made visible or disappeared at various scales and how their (in)visibility is mobilised by other actors for profit. We point to three heterogeneous forms of (in)

A Lightweight Terrain‐Constraint Model for Wind Spatial Downscaling
Journal of Geophysical Research: Machine Learning and Computation, Volume 2, Issue 2, June 2025.Abstract High‐resolution wind fields has always been the goal of refined meteorological forecasting. Using advanced deep learning algorithms for wind downscaling is an effective approach to achieve this goal. However, the lack of physical process understanding in deep learning algorithms results in the inability to accurately reconstruct fine‐scale ...

Solar Cycle Detected in Natural Tritium of Ice Layers Before the Nuclear Era
Journal of Geophysical Research: Atmospheres, Volume 130, Issue 9, 16 May 2025.Abstract The 11‐year cycle of the solar activity affects the production rate of cosmogenic isotopes. For tritium in precipitation, it has been just recently proven that this link exists. Here we show, for the first time, a tritium ice core time series which extends back to 1923, covering a time period that avoids the presence of artificial tritium from
