We investigate the electromagnetic transitions of singly charmed baryons with spin $3/2$, based on a pion mean-field approach, also known as chiral quark-soliton model, taking into account rotational $1/{N}_{c}$ corrections and effects flavor SU(3) symmetry breaking. examine valence- sea-quark contributions to transition form factors find that quadrupole dominate over those valence-quark ones i...

purpose : to evaluate outcome of surgically slanting extraocular muscle insertions in a and v-pattern strabismus methods : in this prospective non-randomized interventional case series, we created a slanting surgical reinsertion line with a 3- 4 mm difference between upper and lower corners of the muscles in 16 patients with a or v strabismus (v-exotropia in 10 patients, a-exotropia in 1 patien...

In the 3-3-1 model with right-handed neutrinos (331RHNs), three triplets of scalars engender correct sequence symmetry breaking, SU(3)C×SU(3)L×U(1)X→SU(3)C×SU(2)L×U(1)Y→SU(3)C×U(1)EM, generating mass for all fermions, except neutrinos. Tiny neutrino masses may be achieved by implementing type II seesaw mechanism into model, requiring addition one sextet to original scalar content. As consequenc...

Emission 57Fe Mössbauer spectroscopy (eMS), following the implantation of radioactive 57Mn+ ions, has been used to study temperature dependence hyperfine magnetic field at Fe sites in Ba-doped BiFeO3 (BFO) thin films. 57Mn β decays (t1/2 = 90 s) 14.4 keV state 57Fe, thus allowing online eMS measurements a selection sample temperatures during Mn implantation. The were performed on two film BFO s...

The aim of the present article is investigation newly observed resonances $$\Xi _c(2923)^{0}$$ , _c(2939)^{0}$$ and _c(2965)^{0}$$ which are real candidates to charm-strange baryons. To this end, we calculate mass pole residue ground-state excited 1P 2S spin-1/2 flavor-sextet baryons _{c}^{\prime 0}$$ 0}(1/2^{-})$$ 0}(1/2^{+})$$ with quark content csd, respectively. masses residues spin-3/2 _{c...

The molecular structure of any system may be unambiguously described by its adjacency matrix, A, in which bonds are assigned entry a(ij) = 1 and non-bonded pairs of atoms entry a(ij) = 0. For π-electron-containing conjugated hydrocarbons, this matrix may be modified in order to represent one of the possible Kekulé structures by assigning entry 1 to double bonds and entry 0 to single bonds, lead...

All reagents were purchased from Sigma-Aldrich or Life Technologies and were used as received. Where described below pet. refers to petroleum ether (40–60 °C). All reactions were monitored by thin-layer chromatography (TLC) on pre-coated SIL G/UV254 silica gel plates (254 m) purchased from VWR. Flash column chromatography was carried out with Kiesegel 60 M, 0.04/0.063 mm (200–400 mesh) silica ...
