, 2000 We show that massless RR tadpoles in vacuum configurations with open and unoriented strings are always related to anomalies. RR tadpoles arising from sectors of the internal SCFT with non-vanishing Witten index are in one-to-one correspondence with conventional irreducible anomalies.

The Astrophysical Journal, 2012 Tadpole galaxies have a giant star-forming region at the end of an elongated intensity distribution. Here we use SDSS data to determine the ages, masses, and surface densities of the heads and tails in 14 local tadpoles selected from the Kiso and Michigan surveys of UV-bright galaxies, and we compare them to tadpoles previously studied in the Hubble ...

Light Hadron Spectroscopy on Coarse Lattices with O(a^2) Mean-Field Improved Actions [PDF]
, 1997 The masses and dispersions of light hadrons are calculated in lattice QCD using an O(a^2) tadpole-improved gluon action and an O(a^2) tadpole-improved next-nearest-neighbor fermion action originally proposed by Hamber and Wu.

SU(3) Latent Heat and Surface Tension from Tree Level and Tadpole Improved Actions [PDF]
, 1996 We analyze the latent heat and surface tension at the SU(3) deconfinement phase transition with tree level and tadpole improved Symanzik actions on lattices with temporal extent $N_\tau = 3$ and 4 and spatial extent $N_\sigma/ N_\tau = 4$, 6 and 8.

Tadpoles and Closed String Backgrounds in Open String Field Theory [PDF]
, 2003 We investigate the quantum structure of Witten's cubic open bosonic string field theory by computing the one-loop contribution to the open string tadpole using both oscillator and conformal field theory methods.

Mean-link tadpole improvement of SW and D234 actions [PDF]
, 1997 We investigate a tadpole-improved tree-level-O(a^3)-accurate action, D234c, on coarse lattices, using the mean link in Landau gauge to measure the tadpole contribution.

Computing Topological Indices and Polynomials for Line Graphs
Mathematics, 2018 A topological index is a number related to the atomic index that allows quantitative structure–action/property/toxicity connections. All the more vital topological indices correspond to certain physico-concoction properties like breaking point ...
