In the present study, bacterial community diversities were investigated in the shrimp intestines, outside seawater and culture-associated environments using clone library analysis. Comparative analyses revealed that the bacterial community in the intestinal contents was most similar to that of the sediment. Bacteria in the phyla Proteobacteria and(More)
– Understanding what types of phenomena lead to discontinuous phase transitions in the connectivity of random networks is an outstanding challenge. Here we show that a simple stochastic model of graph evolution leads to a discontinuous percolation transition and we derive the underlying mechanism responsible: growth by overtaking. Starting from a collection(More)
Combining general relativity and gravitational gauge theory, the cosmolog-ical constant is determined theoretically. The cosmological constant is related to the average vacuum energy of gravitational gauge field. Because the vacuum energy of gravitational gauge field is negative, the cosmological constant is positive, which generates repulsive force on(More)
A series of 0-D, 1-D, and 2-D metal-organic compounds through reactions of quinoline-2,3-dicarboxylic acid (2,3-H(2)qldc) with transition metal salts MCl(2), namely, M(2,3-Hqldc)(2)(H(2)O)(2) (M = Co(1), Zn(4) and Cd(7)), [M(3-qlc)(2)(H(2)O)(2)](n) (M = Co(2), Zn(5) and Cd(8)), M(2-qldc-3-OCH(3))(2)(CH(3)OH)(2) (M = Co(3) and Zn(6)) and(More)
After considering mixing with glueball, we give a new mass relation for meson nonet. According to this mass relation and predicted mass of pseu-doscalar glueball given by lattice calculation and effective Hamiltonian, the expected mass of mixed pseudoscalar glueball is about 1.7 Gev. This result is helpful for experimental search for the mixed Isoscalar(More)
