چکیده

We report on a community e‚ort between industry and academia to shape the future of graph query languages. We argue that existing graph database management systems should consider supporting a query language with two key characteristics. First, it should be composable, meaning, that graphs are the input and the output of queries. Second, the graph query language should treat paths as €rst-class citizens. Our result is G-CORE, a powerful graph query language design that ful€lls these goals, and strikes a careful balance between path query expressivity and evaluation complexity.

Radish: Compiling Efficient Query Plans for Distributed Shared Memory

We present Radish, a query compiler that generates distributed programs. Recent efforts have shown that compiling queries to machine code for a single-core can remove iterator and control overhead for significant performance gains. So far, systems that generate distributed programs only compile plans for single processors and stitch them together with messaging. In this paper, we describe an ap...

Three Graceful Operations

A graph of size n is said to be graceful when is possible toassign distinct integers from {0, 1, . . . , n} to its verticesand {|f(u)−f(v)| : uv ∈ E(G)} consists of n integers. Inthis paper we present broader families of graceful graphs; these families are obtained via three different operations: the third power of a caterpillar, the symmetric product of G and K2 , and the disjoint union of G a...

Ag/Pt Core-Shell Nanoparticles on Graphene Nanocomposite for Effective Anodic Fuels Electro-oxidation

The nanocomposite consists of the Ag as a core and Pt as shell on the surface of graphene nanosheets (Ag/Pt-G) was synthesized with a simple method and used as a novel electrochemical platform for an efficient catalyst for oxidation of the ethanol, methanol and formic acid. The morphology and electrochemical properties of Ag/Pt-G nanocomposite were investigated by TEM, X-ray diffraction, and vo...

یک الگوریتم خطی برای مساله ی پیداکردن هسته ی درخت های بازه ای وزندار

In this paper we consider the problem of finding a core of weighted interval trees.  A core of an interval graph is a path contains some intervals of graph so that the sum of distances from all intervals to this path is minimized. We show that intervals on core of a tree should be maximal, then a linear time algorithm is presented to find the core of interval trees
