In this paper, we introduce and study the concepts of prime left, semiprime left and irreducible left hyperideals in ternary semihyper- groups and investigate some basic properties of them. We introduce the concepts of hyper lter and hypersemilattice congruence of ternary semi- hypergroups. We give some characterizations of hyper lters in ternary semihypergroups. Some relationships between hype...

In this paper we propose a new tabu search hyperheuristic which makes individual low level heuristics tabu dynamically using an analogy with the Binary Exponential Back Off (BEBO) method used in network communication. We compare this method to a reduced Variable Neighbourhood Search (rVNS), greedy and random hyperheuristic approaches and other tabu search based heuristics for a complex real wor...

In this study, electronic structures of ground state of pure vanadium sub-nano clusters, Vn (n=2-5), and their interactions with small ligands for example CO and triplet O2 molecules are investigated by using density functional theory (DFT) calibration at the mPWPW91/QZVP level of theory. The favorable orientations of these ligands in interaction with pure vanadium sub-nano clusters were determ...

In this paper we deal with the impact of multi and many-core processor architectures on simulation. Despite the fact that modern CPUs have an increasingly large number of cores, most softwares are still unable to take advantage of them. In the last years, many tools, programming languages and general methodologies have been proposed to help building scalable applications for multi-core architec...

 Background: Generalized joint hyper mobility predisposes some individuals to a wide variety of musculoskeletal complaints. Given the critical role of scapular position in function of shoulder, the aim of this study was to compare scapular position between persons with and without general joint hyper mobility. Methods: By nonprobability sampling 30 hyper mobile persons at average of 22.86 ±2.77...

Assume we are given a Dirichlet group D . Recent developments in descriptive measure theory [27] have raised the question of whether there exists a multiply Borel and abelian path. We show that the Riemann hypothesis holds. Hence it has long been known that every unconditionally embedded, hyper-associative, measurable factor acting pairwise on an arithmetic point is trivial and super-essentiall...

DOCK8 immunodeficiency syndrome (DIDS) is a combined immunodeficiency characterized by recurrent viral infections, severe atopy, and early onset malignancy. Genetic studies revealed large, unique deletions in patients from different families and ethnic backgrounds. Clinical markers of DIDS include atopic dermatitis, allergies, cutaneous viral infections, recurrent respiratory tract infections, ...

The Transversal Hypergraph Problem is the problem of generating, given a hyper-graph, the set of its transversals, i.e. the hypergraph whose hyperedges are all minimal hitting sets of the given one. This problem turns out to be central in various elds of Computer Science. In this paper we present and experimentally evaluate a new heuristic algorithm for the problem. Experimental results show th...

The present paper applies an Input-Output accounting framework, based on the logical device of vertical hyper-integration, to measure productivity trends across six advanced industrial economies (US, Germany, Japan, UK, France and Italy) during recent decades. Rather than measuring performance from income side economy, as in traditional TFP growth analyses, disaggregated changes are approximate...
