    Following David J. Garrow\u27s 1986 Pulitzer Prize-winning biography, Bearing the Cross, Adam Fairclough makes extensive use of information gleaned from FBI wiretaps as well as other sources in an effort to peruse the soul of the Southern Christian Leadership Conference (SCLC) and its president, Martin Luther King, Jr. Fairclough\u27s subtitle is no accident, for he focuses at least as much on the SCLC as he does on King. Significantly, this emphasis causes him to add a chapter about the SCLC after King\u27s death, a postscript not available in other books about King

    The Complexity of Kings

    A king in a directed graph is a node from which each node in the graph can be reached via paths of length at most two. There is a broad literature on tournaments (completely oriented digraphs), and it has been known for more than half a century that all tournaments have at least one king [Lan53]. Recently, kings have proven useful in theoretical computer science, in particular in the study of the complexity of the semifeasible sets [HNP98,HT05] and in the study of the complexity of reachability problems [Tan01,NT02]. In this paper, we study the complexity of recognizing kings. For each succinctly specified family of tournaments, the king problem is known to belong to Π2p\Pi_2^p [HOZZ]. We prove that this bound is optimal: We construct a succinctly specified tournament family whose king problem is Π2p\Pi_2^p-complete. It follows easily from our proof approach that the problem of testing kingship in succinctly specified graphs (which need not be tournaments) is Π2p\Pi_2^p-complete. We also obtain Π2p\Pi_2^p-completeness results for k-kings in succinctly specified j-partite tournaments, k,j2k,j \geq 2, and we generalize our main construction to show that Π2p\Pi_2^p-completeness holds for testing k-kingship in succinctly specified families of tournaments for all k2k \geq 2

    A photometric study of the intermediate age open cluster King 5

    We report on near IR (J and K bands) observations of an 8×88^{\prime} \times 8^{\prime} region centered on the poorly studied open cluster King 5, for which only optical photometry existed. We found that the cluster is of moderate age (1.0 Gry old), intermediate in age between the Hyades and NGC 752. Combining optical and IR photometry we obtain estimates for cluster parameters. The color excess E(J-K), E(V-I) and E(V-K) are 0.50, 1.10 and 2.45, respectively. The true distance modulus turns out to be (mM)0)=11.40±0.15(m-M)_0) = 11.40\pm 0.15. As a consequence, King 5 is 1.9 kpc far from the Sun.Comment: 7 pages, 6 eps figures, accepted for pubblication in Astronomy and Astrophysic

    Segre numbers, a generalized King formula, and local intersections

    Full text link
    Let J\mathcal J be an ideal sheaf on a reduced analytic space XX with zero set ZZ. We show that the Lelong numbers of the restrictions to ZZ of certain generalized Monge-Amp\`ere products (ddclogf2)k(dd^c\log|f|^2)^k, where ff is a tuple of generators of J\mathcal J, coincide with the so-called Segre numbers of J\mathcal J, introduced independently by Tworzewski and Gaffney-Gassler. More generally we show that these currents satisfy a generalization of the classical King formula that takes into account fixed and moving components of Vogel cycles associated with J\mathcal J. A basic tool is a new calculus for products of positive currents of Bochner-Martinelli type. We also discuss connections to intersection theory

    McKay correspondence for Landau-Ginzburg models

    In this paper we prove an analogue of the McKay correspondence for Landau-Ginzburg models. Our proof is based on the ideas introduced by T. Bridgeland, A. King and M. Reid, which reformulate and generalize the McKay correspondence in the language of derived categories, along with the techniques introduced by J.-C. Chen

    Synthetic and Complex Media for the Rapid Detection of Fluorescence of Phytopathogenic Pseudomonads: Effect of the Carbon Source

    Get PDF
    Fluorescence is of diagnostic value for differentiating among species of aerobic pseudomonads (R. Y. Stanier, N. J. Palleroni, and M. Doudoroff, J. Gen. Microbiol. 43:159, 1966). The standard medium for detecting fluorescence is Medium B (E. 0. King, M. K. Ward, and D. E. Raney, J. Lab. Clin. Med. 44:301, 1954), which supports fluorescent pigment production of most pseudomonads tested (0. Jessen, Pseudomonas aeruginosa and other green fluorescent pseudomonads, A taxonomic study, Munksgaard, Copenhagen, 1965; R. Y. Stanier et al., J. Gen. Microbiol. 43:159, 1966). Minerals (J. V. King, J. J. R. Campbell, and B. A. Eagles, Can. J. Res. C 26:514, 1948), amino acids (J. De Ley, Ann. Rev. Microbiol. 18:17, 1964), and peptones (E. 0. King et al., J. Lab. Clin. Med. 44:301, 1954) affect fluorescence. The effect of carbon sources had not been shown. Although glycerol, glucose, or maltose can be used interchangeably in Medium B for detecting fluorescence of most fluorescent pseudomonads, this report shows that these carbon sources are not equivalent for phytopathogenic pseudomonads
