The machinery at the eukaryotic replication fork has seen many new structural advances using electron microscopy and crystallography. Recent structures of eukaryotic replisome components include the Mcm2-7 complex, the CMG helicase, DNA polymerases, a Ctf4 trimer hub and the first look at a core replisome of 20 different proteins containing the helicase, primase, leading polymerase and a laggin...

In this position paper, a product derivation process is described, which is based on specifications of known customer requirements, features, artifacts in a knowledge base. In such a knowledge base a model about all kinds of variability of a combined software/hardware systems are represented by using a logical-based representation language. Having such a language, a machinery which interprets t...

Data used for machinery condition monitoring contains mainly the same information as that obtained under normal operation conditions. The traditional practice of feature extraction, which uses such data directly, suffers from low signal-to-noise ratio. This paper presents a method that uses an inverse filter to separate the information contents of the data, so that the feature extraction can be...

This paper describes the dlvhex SPARQL plugin, a query processor for the upcoming Semantic Web query language standard by W3C. We report on the implementation of this languages using dlvhex, a flexible plugin system on top of the DLV solver. This work advances our earlier translation based on the semantics by Perez et al. towards an engine which is fully compliant to the official SPARQL specifi...

In many applications, the reliability relation associated with available information is only partially defined, while most of existing uncertainty frameworks deal with totally ordered pieces of knowledge. Partial pre-orders offer more flexibility than total pre-orders to represent incomplete knowledge. Possibilistic logic, which is an extension of classical logic, deals with totally ordered inf...

The problem of prettyprinting in generated programming environments is addressed. A practical solution for the prettyprinting process itself as well as for the handling of comments is given. A new box-language is presented for specifying prettyprint rules in an algebraic way. Both the syntax and the semantics of this box-language are formalized. Instead of designing and implementing a formattin...

This paper presents a generic anytime forward-search constraint-based algorithm for solving planning problems expressed in the CNT framework (Constraint Network on Timelines). It is generic because it allows many kinds of search to be covered, from complete tree search to greedy search. It is anytime because some parameter settings, together with domain-specific knowledge, allow high quality pl...

the main objective of this study was to determine the economical level of inputs applied in production of sugar beet by eglid region farmers. therefore data set was obtained from 55 farmers through interview and completing questionnaire. the farmers were selected based on a two-stage random sampling method.  marginal productivity of inputs was studied using cobb –douglasand transendental produc...

the energy efficiency, greenhouse gas (ghg) emissions, and carbon efficiency of paddy rice production were analysed in sari in the mazandaran province of iran during 2011–2012. data was collected through questionnaires and interviews with paddy producers. the results showed that the net energy gain was 27,932 mj ha-1 and energy efficiency was 1.83 during production. the results of the cobb-doug...
