Relational databases are valuable resources for learning novel and interesting relations and concepts. Relational learning algorithms learn the Datalog definition of new relations in terms of the existing relations in the database. In order to constraint the search through the large space of candidate definitions, users must tune the algorithm by specifying a language bias. Unfortunately, speci...

the inhibition of pathogens growth as well as the shelf-life extension of seafood as a perishable product using safe methods is one of the most important issues that have been attracted fisheries and food science researcher’s attention. the purpose of this study was to evaluate the inhibitory effect of bunium persicum essential oil (eo) on inoculated listeria monocytogenes growth in simulated b...

For any non-trivial abelian group A under addition a graph $G$ is said to be $A$-textit{magic}  if there exists a labeling $f:E(G) rightarrow A-{0}$ such that, the vertex labeling $f^+$  defined as $f^+(v) = sum f(uv)$ taken over all edges $uv$ incident at $v$ is a constant. An $A$-textit{magic} graph $G$ is said to be $Z_k$-magic graph if the group $A$ is $Z_k$  the group of integers modulo $k...

For any h in N , a graph G = (V, E) is said to be h-magic if there exists a labeling l: E(G) to Z_{h}-{0} such that the induced vertex set labeling l^{+: V(G) to Z_{h}} defined by l^{+}(v)= Summation of l(uv)such that e=uvin in E(G) is a constant map. For a given graph G, the set of all for which G is h-magic is called the integer-magic spectrum of G and is denoted by IM(G). In this paper, the ...

THE PRINCIPAL CONCLUSIONS THAT SEEM TO ME JUSTIFIED ARE AS FOLLOWS: 1. The fluorescent pigment formed by some varieties of B. pyocyaneus is produced under conditions identical with those governing the production of the pigment by other "fluorescent bacteria." 2. The production of pyocyanin is not dependent upon the presence of either phosphate or sulfate in the culture medium. It is formed in n...

We analyze the Hessian matrix of the black hole potential of N = 8, d = 4 supergravity, and determine its rank at non-BPS critical points, relating the resulting spectrum to non-BPS solutions (with non-vanishing central charge) of N = 2, d = 4 magic supergravities and their “mirror” duals. We find agreement with the known degeneracy splitting of N = 2 non-BPS spectrum of generic special Kähler ...
