Superconformal blocks and crossing symmetry equations are among central ingredients in any superconformal field theory. We review the approach to these objects rooted harmonic analysis on group that was put forward [J. High Energy Phys. 2020 (2020), no. 1, 159, 40 pages, arXiv:1904.04852] 10, 147, 44 arXiv:2005.13547]. After lifting conformal four-point functions group, we explain how obtain co...

Under the guidance of petroleum geology, on basis in-depth understanding geological characteristics D block such as structure and sedimentation law oil gas enrichment, this paper discusses reservoir potential selects target block. The study shows that is a fault nose controlled by reverse normal fault, has controlling effect its provenance, formation distribution.

background: association between the vitamin d deficiency and metabolic syndrome (mets) has previously been noted and reported to be controversial. the aim of this study was to determine the association of serum 25 (oh) d level and vitamin d dietary intake with mets among iranian population . methods: this analytical study was conducted on 122 patients with mets based on the atpiii criteria and ...

In this paper we show the usage of robust multivariate statistical methods in geostatistics. A usual procedure to estimate the values of variables (e.g. geochemical variables) measured at certain points of a region is to apply geostatistical methods like Krige estimation (based on the estimation of variograms). Here we emphasize robust principal component and factor analysis for the preliminary...

Background Vitamin D deficiency is associated with physiologic changes that are similar to pathogenesis of preeclampsia. Although association of vitamin D and preeclampsia has been studied previously, their results are not consistent. The aim of this study was to investigate the relationship of serum vitamin D and calcium with preeclampsia severity. Materials and Methods: This case- control st...

The RH blood group locus from RhD-positive donors is composed of two closely related genes, RHCE and RHD, encoding the Cc/Ee and D antigens, respectively. The major Rh antigen, D, is serologically defined as a mosaic of at least nine determinants (epD1 to epD9), and the lack of expression of some of these D epitopes at the surface of variant red blood cells defines the D category phenotypes. In...

We investigate the possibility of observing the direct CP violation in the decay modes B → D0D− s and D0D− within the Standard Model. Including the contributions arising from the tree, annihilation, QCD as well as electroweak penguins with both timeand space-like components, we find that the direct CP asymmetry in B → D0D− s is very small ∼ 0.2 % but in B → D0D− decay it can be as large as 4%. ...
