Quantum gravity stability of isotropy in homogeneous cosmology
(North-Holland, 2011)It has been shown that anisotropy of homogeneous spacetime described by the general Kasner metric can be damped by quantum fluctuations coming from perturbative quantum gravity in one-loop approximation. Also, a formal ... -
Radiative neutron capture cross sections measurement of 70Ge at n_TOF CERN facility and its relevance for stellar nucleosynthesis
(2019)Stellar nucleosynthesis is the name given to the nuclear reactions taking place in stars to create the nuclei of the chemical elements. Elements heavier than iron/nickel are dominantly created by neutron capture reactions. ... -

Relativistic reflection from accretion disks in Seyfert galaxies and black-hole binaries: black hole spin and geometrical parameters of the X-ray source and the disk
(2023)In the last few decades, the development of observational techniques and the continuous improvement of measuring instruments have enabled a deeper understanding of the nature of compact objects. As a result of the ... -
Results of KPFM measurements of the MoO3 monolayer, 2020/38/E/ST3/00293, SONATA BIS (dataset)
(2022)The data includes images of the topography and contact potential distribution for the HOPG surface covered with the MoO3 monolayer. The surface coverage is less than 1ML, allowing the substrate to be partially exposed. The ... -
Scaling violation and the inelasticity of very high energy proton–proton interactions
(North-Holland, 2011)The pseudorapidity measurements at LHC, although in the central region only, allows us to perform preliminary tests of the multiparticle production extrapolation formula inspired by the analysis of recent cosmic ray data. ... -
Search for patterns by combining cosmic-ray energy and arrival directions at the Pierre Auger Observatory
(Springer Berlin Heidelberg, 2014)Energy-dependent patterns in the arrival directions of cosmic rays are searched for using data of the Pierre Auger Observatory. We investigate local regions around the highest-energy cosmic rays with E≥6×10^19 eV by ... -
Semientwining Structures and Their Applications
(Hindawi Publishing Corporation, 2012-10-31)Semientwining structures are proposed as concepts simpler than entwining structures, yet they are shown to have interesting applications in constructing intertwining operators and braided algebras, lifting functors, ... -
