Alagille syndr.me(ALGs;OMIM#118450)is a highlyvar.able,multi-systemic,autosomal dominant disor.er.caused by mutations in the Jagged canonical Notch Ligand 1(JAG1)gene(20p12.2)or.in the Neur.genic locus notch homolog pr.tein 2(NOTcH2)gene(1p13).^(1)It pr.mar.ly affects the liver.hear.,eyes,face,kidney,skin,ver.ebr.e,and skeleton.^(1,2)The JAG1 gene has 26 exons and about 90%of the ALGs.c.ses r.sult fr.m pathogenic var.ants in the JAG1 and ar.und 7%of cases have deletions in chr.mosome 20 that include this gene.

In this ar.icle, we investigate the nonr.lativistic quantum motion of a char.ed par.icle within a r.tating fr.me, taking into account the Ahar.nov–bohm(Ab) effect and a unifor. magnetic field. Our.analysis entails the der.vation of the equation of motion and the cor.esponding r.dial equation to descr.be the system. solving the r.sulting r.dial equation enables us to deter.ine the eigenvalues and eigenfunctions, pr.viding a clear.expr.ssion for.the ener.y levels. Fur.her.or.,our.numer.cal analysis highlights the substantial influence of r.tation on both ener.y levels and optical pr.per.ies. specifically, we evaluate the photoionization cr.ss-s.c.ion with and without the effects of r.tation. To elucidate the impact of r.tation on the photoionization pr.cess of the system, we pr.sent gr.phics that offer.an appealing visualization of the intr.ns.c.natur. of the phys.c. involved.

backgr.und The invasion s.c.ess of intr.duced fr.shwater.fishes is influenced by many factor., including ecological, species, and s.c.oeconomic char.cter.stics. Most studies that document the impor.ance of these char.cter.stics ar. conducted at local scales and/or.focus on a single step of the invasion pr.cess.
