Aims. We present the results of an intensive six-month optical continuum reverberation mapping campaign Seyfert 1 galaxy PG 2130+099 at redshift z = 0.063. The ground-based photometric monitoring was conducted on a daily basis with robotic 46 cm telescope WISE observatory located in Israel. Specially designed narrowband filters were used to observe central engine active galactic nucleus (AGN), ...

We analyse the M-theoretic generalisation of the tangent space structure group after reduction of the D = 11 supergravity theory to two space-time dimensions in the context of hidden Kac–Moody symmetries. The action of the resulting infinitedimensional ‘R symmetry’ group K(E9) on certain unfaithful, finite-dimensional spinor representations inherited from K(E10) is studied. We explain in detail...

Cross-sectional research has indicated that the psychological variables of protective motive theory and normative focus are related to avoidance behaviors around going out or contacting others during COVID-19 pandemic. However, there been no longitudinal investigating whether these predict similar behaviors. The aim this study was examine predicted such immediately after termination pandemic st...

Abstract Aim To present our original method for surgical treatment of patients with lateral incisional hernia (LIH) Material and Method Patients LIH simultaneous presence a middle (MIH) were treated by technique based on the principles anterior component separation sublay technique: a) skin subcutaneous tissue incision along midline MIH dissection; b) dissection in direction to Spiegel line or ...

We investigate the static potential in the confinement phase of the SU(2) Higgs model on the lattice, where this model is expected to have properties similar to QCD. We observe that Wilson loops are inadequate to determine the potential at large distances, where the formation of two color-neutral mesons is expected. Introducing smeared fields and a suitable matrix correlation function, we are a...
