Unified Parallel C (UPC) extends the C programming language (ISO C 99) with explicit parallel programming support for the partitioned global address space (PGAS), which provides a global memory space with localized partitions to each thread. Like its ancestor C, UPC is a low-level language that emphasizes code efficiency. The absence of dynamic (and static) safety checks allows programmer overs...

A popular theory of self-organized criticality relates the critical behavior of driven dissipative systems to that of systems with conservation. In particular, this theory predicts that the stationary density of the abelian sandpile model should be equal to the threshold density of the corresponding fixed-energy sandpile. This “density conjecture” has been proved for the underlying graph Z. We ...

This young man presented initially and repeatedly over a period of twenty years with symptoms of irritability, depressed and withdrawn mood, impulsivity, out-of-control behavior, and suicidal ideation and behavior. These symptoms occurred with disabling intensity at ages 3 year, 6 1/2 years, and 8 1/2 years, when he had not yet been adequately diagnosed and treated with appropriate psychopharma...

Computer solutions Multiphysics 3.5a software was used for simulating the two-dimensional copper migration including sorption process through the saturated zone of the soil in the presence of permeable reactive barrier for equilibrium condition. The 1:3 mixture of waste foundry sand and Kerbala’s sand was used as filling material for this barrier. The waste foundry sand was represented the reac...

the dispersibility of graphene is modeled as a mathematical function of the molecular structure of solvent represented by simplified molecular input-line entry systems (smiles) together with the graph of atomic orbitals (gao). the gao is molecular graph where atomic orbitals e.g. 1s1, 2p4, 3d7 etc., are vertexes of the graph instead of the chemical elements used as the graph vertexes in the tra...

Sand dripping in 1 dimensional Sand Pile Model is rst studied. Patterns and signals appear. Their behaviors and interactions are explained and asymptotic approximations are made. The total collapsing time of a single stack of sand is linear in function of the number of grains.
