On realizations of Lie algebras
Acta PolytechnicaWe discuss and compare the main methods for constructing of Lie vector fields from the given Lie algebra structure constants. Generic realizations of three conformal algebras are obtained by the algebraic method and all realizations of the three ...

The Local Group as a time machine: studying the high-redshift Universe with nearby galaxies [PDF]
, 2015 We infer the UV luminosities of Local Group galaxies at early cosmic times ($z \sim 2$ and $z \sim 7$) by combining stellar population synthesis modeling with star formation histories derived from deep color-magnitude diagrams constructed from Hubble ...

Protein pyrophosphorylation by inositol pyrophosphates — detection, function, and regulation
FEBS Letters, EarlyView.Protein pyrophosphorylation is an unusual signaling mechanism that was discovered two decades ago. It can be driven by inositol pyrophosphate messengers and influences various cellular processes. Herein, we summarize the research progress and challenges of this field, covering pathways found to be regulated by this posttranslational modification as ...

p-local finite group cohomology
, 2011 We study cohomology for $p$-local finite groups with non-constant coefficient systems. In particular we show that under certain restrictions there exists a cohomology transfer map in this context, and deduce the standard consequences.Comment: 32 pages ...

Yersinia pestis genomes reveal plague in Britain 4000 years ago
Nature Communications, 2023 Extinct lineages of Yersinia pestis, the causative agent of the plague, have been identified in several individuals from Eurasia between 5000 and 2500 years before present (BP). One of these, termed the ‘LNBA lineage’ (Late Neolithic and Bronze Age), has

Locally compact groups and locally minimal group topologies
Fundamenta Mathematicae, 2019 Summary: Minimal groups are Hausdorff topological groups \(G\) satisfying the open mapping theorem with respect to continuous isomorphisms, i.e., every continuous isomorphism \(G\rightarrow H\), with \(H\) a Hausdorff topological group, is a topological isomorphism.

The role of histone modifications in transcription regulation upon DNA damage
FEBS Letters, EarlyView.This review discusses the critical role of histone modifications in regulating gene expression during the DNA damage response (DDR). By modulating chromatin structure and recruiting repair factors, these post‐translational modifications fine‐tune transcriptional programmes to maintain genomic stability.
