Assuming weakly guiding approximation, we examine orbital angular momentum (OAM) mode mixing on account of ellipticity in a fiber and derive a complete set of analytic expressions for spatial crosstalk, using scalar perturbation read more theory that incorporates fully the existing degeneracy between a spatial OAM mode and its degenerate partner ch
Abstract Background Childhood pre-B acute lymphoblastic leukemia (ALL) is a bone marrow (BM) derived disease, which often disseminates out of the BM cavity, where malignant cells to a variable degree can be found circulating in the peripheral blood (PB).Normal pre-B cells are absolutely dependent on BM stroma for survival and differentiation.It is
