Abstract We systematically study the mass spectrum and strong decays of S-wave $${\bar{c}}{\bar{s}} q q$$ c ¯ s q states in compact tetraquark scenario with quark model. The key ingredients model are Coulomb, li...

bacground: wilson's disease is a rare autosomal recessive disorder characterized by toxic accumulation of copper in liver and brain. the disorder is caused by mutations in the atp7b gene, encoding a copper transporting p-type atpase. characterization of the spectrum of mutations in this gene is important both for diagnosis and genetic counseling of the families.materials and methods: we en...

Let M be a closed Riemannian manifold whose sectional curvatures are all negative, and denote by C the set of free homotopy classes of closed curves in M . Negative curvature implies that in each free homotopy class, there is a unique closed geodesic. This defines a marked length spectrum function ` : C → R>0 which assigns to the class g the length `(g) of this closed geodesic. Burns and Katok ...

We predict the spectrum of four $1S$ and eight $1P$ nonstrange strange states in beauty meson family context effective field theory. By union heavy quark theory chiral perturbation theory, mass formalisms for heavy-light mesons are defined. Our analysis uses expressions involving, first time, full leading self-energy corrections power to limits. The counterterms present these fitted using avail...
