Witryna27 lut 2024 · Rigosertib (ON-01910.Na) is a small-molecule member of the novel synthetic benzyl-styryl-sulfonate family. It is currently in phase III clinical trials for several myelodysplastic syndromes and leukemias and is therefore close to clinical translation. The clinical progress of rigosertib has been hampered by a lack of understanding of … thimbles for sewing leatherWe consider impurities in the simplest 1D Hatano–Nelson chain43, which already exhibits nearly the full scope of impurity-induced phenomena in more generic lattices. An impurity is represented as a modified coupling between the first and last sites: with μ± = μe±α, μ controlling the local impurity, α > 0 and x = … Zobacz więcej To understand why SFA occurs, we analytically solve for the eigenstates \({{{\Psi }}}_{n}=\mathop{\sum }\nolimits_{x}^{L}{\psi }_{x,n}{\hat{c}}_{x}^{\dagger … Zobacz więcej The discussions above imply a duality between PBCs at μ = 1 and quasi-PBCs at μ = e2α.
