groundwater is one of the common resources in varamin plain, but due to over extraction it has been exposed to ruin. this phenomenon will lead to economic and environmental problems. on the other hand, the world is expected to face with more stochastic events of water supply. furthermore, incorporating stochastic consideration of water supply becomes more acute in designing water facilities. th...

in this paper, we analyze the effect of lack of capital investment on energy projects using game theory in the guise of cooperative games. we focus on the energy projects in the provincial level as case study during 2010-2011. therefore, we design a theoretical model of the lack of capital investment as a factor influencing the implement of energy projects. in the experimental section, we deter...

this article aims to study an important principle in discourse analysis, which belongs to paul grice, the contemporary philosopher. he believes that in addition to giving and taking information during a conversation, people also show their cooperation with each other, and so he suggests the ‘cooperative principle’ which contains some principles of subtext. since the cooperative principle is wit...

The proliferation of wireless local area network (WLAN) deployments in enterprises, public areas, and homes will cause frequent geographical coverage overlap among multiple networks. A recent growing interest is the coordination among WLAN providers for efficient resource management over a large coverage area. While radio resource management for a single WLAN has been studied extensively, littl...

General properties of the antagonistic biomolecular interactions between viruses and their hosts (exogenous interactions) remain poorly understood, and may differ significantly from known principles governing the cooperative interactions within the host (endogenous interactions). Systems biology approaches have been applied to study the combined interaction networks of virus and human proteins,...

Base stacking plays an important role in excited state dynamics in polynucleotides. However, it is poorly understood how stacking geometries influence the formation of and relaxation from excites states. Natural poly(dA)·poly(dT) adopts a B-form structure with extensive geometrical overlap between adjacent stacked adenines while the synthetic, locked ribose analogue (LNA), adopts the A-form str...

To achieve proper spatiotemporal control of gene expression, transcription factors cooperatively assemble onto specific DNA sequences. The ETS domain protein monomer of GABPα and the B-ZIP domain protein dimer of CREB1 cooperatively bind DNA only when the ETS ((C)/GCGGAA GT: ) and CRE ( GT: GACGTCAC) motifs overlap precisely, producing the ETS↔CRE motif ((C)/GCGGAA GT: GACGTCAC). We designed a ...

Regulation of muscle contraction is a very cooperative process. The presence of tropomyosin on the thin filament is both necessary and sufficient for cooperativity to occur. Data recently obtained with various tropomyosin isoforms and mutants help us to understand better the structural requirements in the thin filament for cooperative protein interactions. Forming an end-to-end overlap between ...
