Fast radio bursts (FRBs) probe the total column density of free electrons in intergalactic medium (IGM) along path propagation though dispersion measures (DMs) which depend on baryon mass fraction IGM, i.e., $f_{\rm IGM}$. In this letter, we investigate large-scale clustering information DMs to study evolution When combining with Planck 2018 measurements, could give tight constraints IGM}(z)$ f...

Basic research in the chemistry of hexameric resorcin[4]arenes and pyrogallol[4]arenes during the last decade is reviewed. Applications of NMR methods to determine solution structures, host guest properties and exchange dynamics are discussed. The scientific issue is the behavior of molecules in small spaces; the challenge is to translate this information to practical applications in, say, cata...

Study objective — assessment of the humoral and cell-mediated immunity features in COVID-19 convalescents three months after their discharge from hospital. Material Methods The study involved 78 who, depending on profile specific IgM IgG antibodies to SARS-CoV-2, were divided into groups. control group consisted 50 volunteers. Detection blood serum was performed by ELISA. Determination CRP conc...
