One of the problems encountered in CE separations of basic compounds is the adsorption of analytes onto the negatively charged capillary wall which could lead to poor repeatability of migration time and peak area. Additionally, separation of enantiomers of chiral of basic drugs is commonly carried out in low pH buffer which contributes to strong ionic interaction of the cationic drug ions with ...

An important property of electromagnetic fields, which arises from the interaction between fields and chiral molecules, is called optical chirality. By enhancing this field property, while maintaining constant input power, we are able to increase absorption of circularly polarized light by chiral molecules of a certain handedness. This enhancement is achieved through the use of achiral plasmoni...

Abstract For any congruence subgroup $\Gamma $, we study the vertex operator algebra $\Omega ^{ch}(\mathbb H,\Gamma )$ constructed from $-invariant global sections of chiral de Rham complex on upper half plane, which are holomorphic at all cusps. We construct a basis in terms modular forms $ and compute its character. show that operations determined by modification Rankin–Cohen brackets forms.

Semileptonic decays of vector mesons $$\rho $$ , $$\omega ϕ into a pion and lepton pair $${{e}^{ + }}{{e}^{ - }},{{\mu }^{ }}{{\mu }}$$ are described in the chiral Nambu–Jona–Lasinio (NJL) model.

Abstract In our previous studies, we analyzed the two-body strong decays of low-lying Ω baryon states within a chiral quark model. The results showed that mass, total width, and two body decay could be well reproduced with spin-parity J^P=3/2^- state \Omega^*|1P_{3/2^-}\rangle classified in Stimulated by new observations three-body process \Omega(2012)^...

Whereas a quantum spin liquid (QSL) phase has been identified in the ${J}_{1}\text{\ensuremath{-}}{J}_{2}$ Heisenberg model on triangular lattice via numerical calculations, debate persists about whether or not such QSL is gapped gapless with contradictory conclusions from different techniques. Moreover, information excitations and dynamics crucial for experimental detection of phase. In this p...

We study the D → σπ, D → ρπ, B− → σπ−, B− → ρ0π− and B̄ → ρ±π∓ decays in a valence quark triangle model, incorporating chiral symmetries. We find a good agreement with recent experimental data for D → σπ and for D → ρπ. We point out that a long-distance contribution due to the axial vector a1 meson pole, calculated by using chiral symmetry, can be relevant to explain D → ρπ and for lowering the ...

synthesis of some new monocyclic β-lactams containing a quaternary carbon center via a [2+2]cycloaddition reaction is described. the reaction of achiral diphenyl ketene with chiral aldimines derivedfrom chiral 2, 3, 4, 6-tetra-o-acetyl-β-d-galactopyranosylamine, 2, 3, 4, 6-tetra-o-acetyl-β-dglucopyranosylamine and different benzaldehydes resulted in the formation of β-lactams as singlediastereo...

The loop algebra L(sl2) symmetry is found in a sector of the nilpotent BazhanovStroganov model. The Drinfeld polynomial of a L(sl2)-degenerate eigenspace of the model is equivalent to the polynomial [4, 5, 10–14] which characterizes a subspace with the Isinglike spectrum of the superintegrable chiral Potts model.
