Unfixed metaphase chromosome preparations from human lymphocyte cultures were immunofluorescently labelled using antibodies to defined histone epitopes. Both mouse monoclonal antibody HBC-7, raised against the N-terminal region of H2B, and rabbit serum R5/12, which recognizes H4 acetylated at Lys-12, gave non-uniform labelling patterns, whereas control… (More)

In Ch], Cheeger proved the following general lower bound for the rst eigenvalue 1 of a closed Riemannian manifold: Theorem ((Ch]): 1 1 4 h 2 ; where h = inf N area(N) min(vol(A); vol(B)) where N runs over (possibly disconnected) hypersurfaces of M which divide M into two pieces A and B, and where area denotes (n ? 1)-dimensional volume, and vol denotes… (More)

We investigate the relation between the Korteweg-de Vries and modified Korteweg-de Vries equations (KdV and mKdV), and find a new algebro-analytic mechanism, similar to the Lax L-A pair, which involves a family of first-order operators Q λ depending on a spectral parameter λ, instead of the third-order operator A. In our framework, any generalized… (More)

The human lens is comprised largely of crystallin proteins assembled into a highly ordered, interactive macro-structure essential for lens transparency and refractive index. Any disruption of intra- or inter-protein interactions will alter this delicate structure, exposing hydrophobic surfaces, with consequent protein aggregation and cataract formation.… (More)

For a large class of two body potentials, we solve two of the main problems in the spectral analysis of multiparticle quantum Hamiltonians: explicitly, we prove that the point spectrum lies in a closed countable set (and describe that set in terms of the eigenvalues of Hamiltonians of subsystems) and that there is no singular continuous spectrum. We… (More)

We consider the problem of enumerating permutations in the symmetric group on n elements which avoid a given set of consecutive pattern S, and in particular computing asymptotics as n tends to infinity. We develop a general method which solves this enumeration problem using the spectral theory of integral operators on L 2 ([0, 1] m), where the patterns in S… (More)

The cellular response, in terms of cell cycle arrest(s) and apoptosis, to radiation-induced DNA damage was studied. Experiments were performed on both mitogen-stimulated and resting peripheral blood lymphocytes (PBLs) from normal and cancer-prone (C-P) individuals. The C-P individuals comprised three patients carrying germline p53 mutations and three… (More)
