The Segregation Distorter system of Drosophila melanogaster consists of two major elements, Sd and Rsp. There are two allelic alternatives of Rsp-sensitive (Rsp(s)) and insensitive (Rsp(i)); a chromosome carrying Rsp(i) is not distorted. According to the model proposed by Hartl (1973), these two elements interact to cause segregation distortion. For a sperm to complete the maturation process, i...

In the Stream Reasoning (SR) research, working prototypes often came along with foundational investigations. For RDF Stream Processing (RSP) in particular, RSP engines empirically proved the approach feasibility and paved the road to application design and comparative analyses. Observing these real systems highlighted their heterogeneity and fosters new foundational achievements: RSP-QL, i.e. a...

A number of RDF Stream Processing (RSP) systems have been developed to support processing of streaming Linked Data, however, due to the lack of a standard query language they all provide different extensions. The RSP Community Group is in the process of standardizing the RSP query language (RSP-QL), which incorporates many features from existing RSP languages. In this paper we present a demo sh...

The retrosplenial cortex (RSP), a brain region frequently linked to processes of spatial navigation, contains neurons that discharge as a function of a rat's head direction (HD). HD cells have been identified throughout the limbic system including the anterodorsal thalamus (ADN) and postsubiculum (PoS), both of which are reciprocally connected to the RSP. The functional relationship between HD ...

The RSP-QL model explains and unifies RDF Stream Processing (RSP) approaches into a more general semantics. It was successfully applied to model C-SPARQL, CQELS-QL and SPARQLstream taking into account the operational semantics of the existing implementations. In this paper, we present Yasper 1.0, an RSP engine that implements RSP-QL semantics. Moreover, we present the challenges we found during...

In the Segregation distorter (SD) system of meiotic drive, a minimum of two trans-acting elements [Sd and E(SD)] act in concert to cause a certain probability of dysfunction for sperm carrying a sensitive allele at the Responder (Rsp) target locus. By employing a number of insertional translocations of autosomal material into the long arm of the Y chromosome, Rsp can be mapped as the most proxi...

Elements of the Segregation Distorter (SD) system of Drosophila melanogaster, Sd and Rsp, were analyzed and the following points were established: (1) The model of multiple alleles at the Rsp(s) locus proposed by Martin and Hiraizumi (1979) is supported by our observations. (2) A modifier of SD, tentatively symbolized M(SD), was found close to cn (2R-57.5). (3) Sd heterozygous males were found ...

In this paper, we have proposed a restricted shared protection (RSP) scheme that provides restriction on the sharing of some of the backup light paths to increase the reliability of the protection in optical network. From the reliability theory, we have proved that the reliability in RSP network is more than that of existing shared protection (SP) network. As failure rate increases, the reliabi...

Graph products are characterized by the existence of non-trivial equivalence relations on the edge set of a graph that satisfy a so-called square property. We investigate here a generalization, termed RSP-relations. The class of graphs with non-trivial RSP-relations in particular includes graph bundles. Furthermore, RSP-relations are intimately related with covering graph constructions. For K2,...

The W3C RDF Stream Processing (RSP) community has proposed a common model and a language for querying RDF streams. However, the current RSP systems significantly differ from each other in terms of performance. In this paper, we propose a unified interface for optimizing a continuous query in heterogeneous RSP systems. To enhance the performance of RSP, a unified interface decomposes a query, re...
