    Notes: Abstract  Cattle DRA and DRB genes, cloned by reverse-transcription polymerase chain reaction, were transfected into mouse L cells. The cattle DR-expressing L-cell transfectant generated was analyzed serologically, biochemically, and functionally. Sequence analysis of the transfected DRB gene clearly showed showed that it was DRB3 allele DRB3 * 0101, which corresponds to the 1D-IEF-determined allele DRBF3. 1D-IEF analysis of the transfectant confirmed that the expressed DR product was DRBF3. Functional integrity of the transfected gene products was demonstrated by the ability of the transfectant cell line to present two antigens (the foot-and-mouth disease virus-derived peptide FMDV15, and ovalbumin) to antigen-specific CD4+ T cells from both the original animal used to obtain the genes, and also from an unrelated DRBF3+ heterozygous animal. Such transfectants will be invaluable tools, allowing us to dissect the precise contributions each locus product makes to the overall immune response in heterozygous animals, information essential for rational vaccine design.

    Taub numbers at future null infinity. II (1994)

    Notes: This work extends the ideas presented in Taub I [Phys. Rev. D 47, 474 (1993)]. Taub numbers are studied as a set of tensorial conservation laws derivable from curves of solutions to the Einstein equations. The zeroth-order Taub numbers for mass and angular momentum are computed using the Penrose–Goldberg superpotential [Phys. Rev. D 41, 410 (1990)]. A superpotential for the higher-order Taub vectors is given and is gauge invariant with respect to the perturbation gauge. Taub numbers are computed for the Schwarzschild and Kerr solutions, Schwarzschild and Kerr viewed as perturbations of Minkowski and Schwarzschild, respectively, and for the stationary perturbations of Schwarzschild. Taub numbers are found to give a tensorial formulation for mass and angular momentum for asymptotically flat spacetimes. A new solution generation technique for asymptotically flat solutions is also presented.

    Notes: A three-parameter family of solutions of Einstein's field equations is given that represents a collapsing perfect fluid with outgoing neutrino flux. Solutions with "naked'' singularities are exhibited. They can be forbidden by requiring pressure less than or equal to the density as a condition of cosmic censorship.

    Notes: We present a solution generating technique for anisotropic fluids which preserves specific Killing symmetries. Anisotropic matter distributions that can be used with the one parameter Ehlers–Geroch transform are discussed. Example space–times that support the appropriate anisotropic stress-energy are found and the transformation applied. The 3+1 black string solution is one of the space–times with the appropriate matter distribution. Use of the transform with a black string seed is discussed. © 2002 American Institute of Physics.

    Angular momentum and Killing potentials (1996)

    Notes: When the Penrose–Goldberg (PG) superpotential is used to compute the angular momentum of an axial symmetry, the Killing potential Qμν(cursive-phi) for that symmetry is needed. Killing potentials used in the PG superpotential must satisfy Penrose's equation. It is proved for the Schwarzschild and Kerr solutions that the Penrose equation does not admit a Qμν(cursive-phi) at finite r and therefore the PG superpotential can only be used to compute angular momentum asymptotically. © 1996 American Institute of Physics.

    Gravitational mass anomaly (1994)
    College Park, Md. : American Institute of Physics (AIP)

    Notes: The mass of gravitational sources differs by a factor of 2 when computed by the Komar superpotential and when computed in the gravitational weak field limit. The difference has been recognized for some time since both the linearized theory and the Einstein pseudotensor yield the same value, different by a factor of 2 from the Komar mass. The great advantage of the Komar superpotential over other methods is its tensorial formulation, however it fails to produce a Noether quantity. A different tensorial method is suggested that is free of the mass anomaly, namely, the zero and first Taub numbers [Phys. Rev. D 47, 474 (1993)] which are indeed Noether quantities. The zeroth Taub number is obtained from the Penrose–Goldberg superpotential [Phys. Rev. D 41, 410 (1990)].

    Notes: Mass and angular momentum of asymptotically flat systems are computed by Taub number τ1. This work extends the Taub number method from a vacuum region outside the central source to a region with stationary electric and magnetic fields while preserving global mass and angular momentum. The Reissner–Nordström and Kerr–Newman solutions are treated. Function spaces for curves of solutions of the coupled Einstein–Maxwell equations are discussed, together with the linearized field equations which are directional derivatives of the field equations along the solution curves in the direction of the perturbation.
