The relational model and its extensions are often considered incompatible with object-orientation. However, on the one hand nested relations provide the complex object features demanded by object models. Particularly, powerful query languages exploit the complex data structure while keeping the advantages of the declarative, set-oriented paradigm. On the other hand, object models provide semant...

A nested reverse transcriptase (RT) PCR assay detected mRNA of the salmonid pathogen Renibacterium salmoninarum in samples of RNA extracts of between 1 and 10 cells. Total RNA was extracted from cultured bacteria, Atlantic salmon (Salmo salar L.) kidney tissue and ovarian fluid seeded with the pathogen, and kidney tissue from both experimentally challenged and commercially raised fish. Followin...

Hybrid rocket engines suffer from the restricted mechanical properties and low regression rates of current polymeric fuel grains. We propose a three-dimensional printed aluminium (Al) nested composite grain with millimetre-scale lattice pores (referred to as Al-L). In this study, breathable Al blades micrometer-scale interconnected (Al-B) combining (Al-B&L) are designed. The formation mechanism...

We propose a notion of focusing for nested sequent calculi for modal logics which brings down the complexity of proof search to that of the corresponding sequent calculi. The resulting systems are amenable to specifications in linear logic. Examples include modal logic K, a simply dependent bimodal logic and the standard non-normal modal logics. As byproduct we obtain the first nested sequent c...

Dependency analysis techniques used for parllelizing compilers can be used to produce coarse grained code for distributed memory systems such as a cluster of workstations. Nested for-loops provide opportunities for this coarse grained parallelization. This paper describes current dependency analysis tests that can be used to identify ways for transforming sequential C code into parallel C code....

The general expression for the local matrix of a quantum chain L(θ) with the site space in any representation of su(3) is obtained. This is made by generalizing L(θ) from the fundamental representation and imposing the fulfilment of the Yang-Baxter equation. With these operators and using a generalization of the nested Bethe ansatz, the Bethe equations for a multistate quantum chain combining t...

We investigate the relationship between the nested organization of mutualistic systems and their robustness against the extinction of species. We establish that a nested pattern of contacts is the best possible one as far as robustness is concerned, but only when the least linked species have the greater probability of becoming extinct. We introduce a coefficient that provides a quantitative me...

In this article, we present a Lyapunov framework for establishing stability with respect to compact set nested interconnection of nonlinear dynamical systems ordered from slow fast according their convergence rates, where each the dynamics is influenced only by slower and successive fastest one. The proposed approach explicitly considers more than two time scales, it does not require modeling m...
