Let G be a group with identity e. Let R be a G-graded commutative ring and let M be a graded R-module. The graded classical prime spectrum Cl.Specg(M) is defined to be the set of all graded classical prime submodule of M. The Zariski topology on Cl.Specg(M); denoted by ϱg. In this paper we establish necessary and sufficient conditions for Cl.Specg(M) with the Zariski topology to be a Noetherian...

The problem of formalizing architectural styles has been recently tackled with the introduction of the concept of architectural type. The internal behavior of the system components can vary from instance to instance of an architectural type in a controlled way, which preserves the absence of deadlock related architectural mismatches proved via the architectural compatibility and interoperabilit...

Total internal reflection fluorescence microscopy (TIRFM) images the plasma membrane-cytosol interface and has allowed insights into the behavior of individual secretory granules before and during exocytosis. Much less is known about the dynamics of the other partner in exocytosis, the plasma membrane. In this study, we report the implementation of a TIRFM-based polarization technique to detect...

Conserved intervals were recently introduced as a measure of similarity between genomes whose genes have been shuffled during evolution by genomic rearrangements. Phylogenetic reconstruction based on such similarity measures raises many biological, formal and algorithmic questions, in particular the labelling of internal nodes with putative ancestral gene orders, and the selection of a good tre...

Despite the huge interest in network resilience to stress, most of the studies have concentrated on internal stress damaging network structure (e.g., node removals). Here we study how networks respond to environmental stress deteriorating their external conditions. We show that regular networks gradually disintegrate as environmental stress increases but disordered networks suddenly collapse at...

There is no better example of the impact of electron tomography on our understanding of cell ultrastructure than the mitochondrion. Mitochondrial cristae were, until recently, represented as random infoldings of the inner membrane, the site of the machinery of oxidative phosphorylation. Electron tomography has revealed, instead, that the cristae define micro-compartments interconnected by narro...

In this study molecular topology based QSAR has been applied to predict the reaction yield and anticancer activity of 18 imidazole and guanidine derivatives. Four properties were evaluated, namely reaction yield, anti prostatic-cancer activity, anti breast-cancer activity and anti lung-cancer activity. The four models have been validated by both internal and cross validation, and also by random...

Dense wavelength division multiplexing (DWDM) has become the dominant transport layer technology for next-generation backbone networks due to its unprecedented capacity scalability. As a result, there is a pressing need to investigate lightpath provisioning in multidomain DWDM networks. Although inter-domain provisioning has been well-studied for packet/cell-switching networks, the wavelength d...

Satellite constellation design is one kind of typical Multiobjective Optimization Problem (MOP). In this paper, aim at feature of high-dimensional decision space, an model-based multiobjective Evolutionary Algorithm(EA) via Self Organization Feature Map(SOM) is put forward for reducing decision space dimension of satellite constellation design: internal topology of input training set in the pop...
