A randomized controlled trial comparing intrathecal sustained-release cytarabine (DepoCyt) to intrathecal methotrexate in patients with neoplastic meningitis from solid tumors.
Standard treatment for neoplastic meningitis requires frequent intrathecal (IT) injections of chemotherapy and is only modestly effective. DepoCyt is a sustained-release formulation of cytarabineExpand

Metric Geometry in Homogeneous Spaces of the Unitary Group of a C*-Algebra. Part II. Geodesics Joining Fixed Endpoints
Abstract.This article focuses on the study of the metric geometry of homogeneous spaces $$\mathcal{P} = U(\mathcal{A})/U(\mathcal{B})$$ (the unitary group of a C*-algebra $$\mathcal{A}$$ modulo theExpand

Spectral Flow and Bifurcation of Critical Points of Strongly Indefinite Functionals
Abstract Our main results here are as follows: Let X λ be a family of 2 π -periodic Hamiltonian vectorfields that depend smoothly on a real parameter λ in [ a ,  b ] and has a known, trivial, branchExpand

Conditional expectations and operator decompositions
For aC*-algebraA with a conditional expectation Φ:A → A onto a subalgebraB we have the linear decompositionA=B⊕H whereH=ker(Φ). Since Φ preserves adjoints, it is also clear that a similarExpand

The left invariant metric in the general linear group
Left invariant metrics induced by the p-norms of the trace in the matrix algebra are studied on the general lineal group. By means of the Euler-Lagrange equations, existence and uniqueness ofExpand
