Invasive aspergillosis (1 is a life-threatening condition in immunocompromised patients. An early diagnosis is of great importance because early treatment may resolve this potentially fatal infection. Recently, the polymerase chain reaction (PCR) has been used successfully in detecting specific DNA of several pathogen. In this study, nested PCR was used to detect DNA specific for A!.pergiflus s...

We introduce the class of possibilistic nested logic programs. These possibilistic logic programs allow us to use nested expressions in the bodies and the heads of their rules. By considering a possibilistic nested logic program as a possibilistic theory, a construction of a possibilistic logic programing semantics based on answer sets for nested logic programs and the proof theory of possibili...

We prove a copying theorem for well-nested multiple contextfree languages: if L = {w#w | w ∈ L0 } has a well-nested m-MCFG, then L has a ‘non-branching’ well-nested m-MCFG. This can be used to give simple examples of multiple context-free languages that are not generated by any well-nested MCFGs.

The generalized nested logit model is a new member of the generalized extreme value family of models. The GNL provides a higher degree of flexibility in the estimation of substitution or cross-elasticity between pairs of alternatives than previously developed generalized extreme value models. The generalized nested logit model includes the paired combinatorial logit and cross-nested logit model...

Self-nested trees present a systematic form of redundancy in their subtrees and thus achieve optimal compression rates by DAG compression. A method for quantifying the degree of self-similarity of plants through self-nested trees has been introduced by Godin and Ferraro in 2010. The procedure consists in computing a self-nested approximation, called the nearest embedding self-nested tree, that ...

SPARQL currently does not include any form of nested queries. In this paper we present a proposal to incorporate nested queries into SPARQL along the design philosophy of SQL nested queries. We present rewriting algorithms and show that all the proposed nested queries can be expressed in a natural and simple extension of SPARQL syntax.

Background: Bovine leukaemia virus (BLV) is the primary cause of enzootic bovine leukaemia which belongs to the HTLV/BLV group of oncogenic retroviruses including Human T-cell leukaemia virus types 1, 2, and 3 and simian T-lymphotropic virus. Due to daily consumption of milk, meat and other dairy by-products, a possible role in appearing human cancers can be assumed for BLV. Materials and Metho...
