An optimal skew-insensitive join and multi-join algorithm for distributed architecture [PDF]
, 2005 The development of scalable parallel database systems requires the design of efficient algorithms for the join operation which is the most frequent and expensive operation in relational database systems.

Hyperosmotic stress induces PARP1‐mediated HPF1‐dependent mono(ADP‐ribosyl)ation
FEBS Letters, EarlyView.Sorbitol‐induced hyperosmotic stress rapidly induces reversible mono(ADP‐ribosyl)ation (MARylation) on PARP1 without the signs of genotoxic signaling. We show that PARP1 autoMARylation is HPF1 dependent and forms hydroxylamine‐resistant O‐glycosidic linkages.

On dynamic colouring of cartesian product of complete graph with some graphs
Journal of Taibah University for Science, 2020 A proper vertex colouring is called a 2-dynamic colouring, if for every vertex v with degree at least 2, the neighbours of v receive at least two colours. The smallest integer k such that G has a dynamic colouring with k colours denoted by $\chi _2(G) $.

Simplicial join via tensor product [PDF]
manuscripta mathematica, 2008 Let \(k\) be a field, \(A\) and \(B\) finitely generated (standard graded) \(k\)-algebras, and \(M\) and \(N\) finitely generated (graded) modules over \(A\) and \(B\) respectively. In this paper, the authors prove several results of the following type, or its variances: ``\(M \bigotimes_k N\) is \({\mathcal P}\) as a \(A\bigotimes_k B\)-module if (or,

FEBS Letters, EarlyView.Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Interleaving by Parts: Join Decompositions of Interleavings and Join-Assemblage of Geodesics [PDF]
, 2023 Metrics of interest in topological data analysis (TDA) are often explicitly or implicitly in the form of an interleaving distance d(I )between poset maps (i.e. order-preserving maps), e.g.

Exploring the Crossing Numbers of Three Join Products of 6-Vertex Graphs with Discrete Graphs
MathematicsThe significance of searching for edge crossings in graph theory lies inter alia in enhancing the clarity and readability of graph representations, which is essential for various applications such as network visualization, circuit design, and data ...

The Crossing Number of Join of the Generalized Petersen Graph P(3, 1) with Path and Cycle
Discussiones Mathematicae Graph Theory, 2018 There are only few results concerning the crossing numbers of join of some graphs. In this paper, the crossing numbers of join products for the generalized Petersen graph P(3, 1) with n isolated vertices as well as with the path Pn on n vertices and with

On Powers of Some Graph Operations [PDF]
Mathematics Interdisciplinary Research, 2018 Let G*H be the product * of G and H. In this paper we determine the rth power of the graph G*H in terms of Gr, Hrand Gr*Hr, when * is the join, Cartesian, symmetric difference, disjunctive, composition, skew and corona product. Then we solve the equation
