Abstract:

The latest trends of integration of the Central and Eastern Europe countries in the global economy increase the need for regional specialization and for the assertion on the markets through competitive advantages based on innovation, knowledge transfer and a rational use of resources. A certainway to meet these needs is to create clusters. This paper focuses on studying the principles and mechanisms of organizing a cluster and aims at developing a functional cluster creation and development algorithm. This paper deals with the study of the principles and mechanisms of cluster organization and

The innovation and development practices of the pharmaceutical industry are of great importance for the continual enhancement of public health. Industrial clusters are one of the important means by which the pharmaceutical industry can be transformed and developed, but there is a lack of research on the evolutionary path and development innovation of pharmaceutical industrial clusters. As a country with a major pharmaceutical industry, the transformation and development path of traditional pharmaceutical industrial clusters in China has important reference value for the sustainable development

Four models at temperatures from 2600 K to 3500 K have been constructed by molecular dynamic simulation. The simulation shows that the liquid has a small amount of defect-cells which are of importance for the diffusion. In particular, the majority of reactions happen via defect-cells SiO5 and OSi3. Moreover, the defect-cells do not uniformly distribute in the liquid, but they have

Unequal clustering mechanism, in combination with inter-cluster multihop routing, provides a new effective way to balance the energy dissipation among nodes and prolong the lifetime of wireless sensor networks.

By a time based competitive clustering algorithm, DEEUC partitions all nodes into clusters of unequal size, in which the clusters closer to the base station have smaller size. The cluster heads of these clusters can preserve some more energy for the inter-cluster relay traffic a

There are limited data examining whether different mechanisms of injury have an effect on post-concussion symptoms.

Abstract:

The absence of magic numbers in bosonic 4He clusters predicted by all theories since 1984 has been challenged by high-resolution matter-wave diffraction experiments. The observed magic numbers were explained in terms of enhanced growth rates of specific cluster sizes for which an additional excitation level calculated by diffusion Monte Carlo is stabilized. The present theoretical study provides an alternative explanation based on a simple independent particle model of the He clusters.

Abstract:

Clusters of regularly spaced direct repeats, separated by unconserved spacer sequences, are ubiquitous in archaeal chromosomes and occur in some plasmids. Some clusters constitute around 1% of chromosomal DNA. Similarly structured clusters, generally smaller, also occur in some bacterial chromosomes. Although early studies implicated these clusters in segregation/partition functions, recent evidence suggests that the spacer sequences derive from extrachromosomal elements, and, primarily, viruses. This has led to the proposal that the clusters provide a defence against viral propagation in cell

Abstract:

Rhodobacter sphaeroides has two chemotaxis clusters, an Escherichia coli-like cluster with membrane-spanning chemoreceptors and a less-understood cytoplasmic cluster. The cytoplasmic CheA is split into CheA4, a kinase, and CheA3, a His-domain phosphorylated by CheA4 and a phosphatase domain, which together phosphorylate and dephosphorylate motor-stopping CheY6. In bacterial two-hybrid analysis, one major cytoplasmic chemoreceptor, TlpT, interacted with CheA4, while the other, TlpC, interacted with CheA3. Both clusters have associated adaptation proteins. Deleting their methyltransferases and m

Abstract:

The evolutional scenario of the resource distribution in the fractal-cluster system which is identified as the “organism” has been suggested. We propose a model in which the resource redistribution dynamics in the closed system is determined with the ultrametric structure of the system’s space. Moreover, each cluster has its own characteristic time of a transfer to the equilibrium state which is determined with the ultrametric size of the cluster. The general equation which determines this dynamics has been written. For the determined type of the resource transitions among clusters, the soluti

Abstract:

In this paper the specific properties of free clusters and the formation of new cluster-assembled materials using the low energy cluster beam deposition (LECBD) technique are discussed. Recent results obtained for free clusters are summarized with special attention to new observed structures. As for the specific structures and properties of cluster-assembled materials, two main aspects are specially emphasized: the memory effect of the free cluster properties leading to the formation of new phases and the effect of the specific nanostructure of the cluster-assembled materials related to the ra

Abstract:

Fullerenes tend to form clusters in different solutions. In this work, a brief survey and some results in the field of investigations of the structure and kinetics of clusters growing in C60 solutions are presented. The general character of this phenomenon for fullerenes is emphasized, and the considerations of mechanisms responsible for the formation and growth of clusters are discussed. We distinguish different types of fullerene solvents by the aggregation mechanism. The kinetics of cluster growth measured via the dynamic light scattering is presented.

Abstract:

Molecular dynamics simulation was adopted to investigate the nanoscale titanium nitride formation at the early formation stage in high-strength low-alloy steel. During the cluster formation process, the nitride clusters were formed through the atom aggregation. The atomic interactions of titanium and nitride atoms were revealed and the cluster property was discussed. The nanoscale titanium nitride clusters own a wide composition, and the cluster formation mechanism was concluded.

Abstract:

Attrition is a common occurrence in cluster randomised trials which leads to missing outcome data. Two approaches for analysing such trials are cluster-level analysis and individual-level analysis. This paper compares the performance of unadjusted cluster-level analysis, baseline covariate adjusted cluster-level analysis and linear mixed model analysis, under baseline covariate dependent missingness in continuous outcomes, in terms of bias, average estimated standard error and coverage probability. The methods of complete records analysis and multiple imputation are used to handle the missing

Abstract:

Heartbeat mechanism is the key technology of fault detection in cluster system, and the performance of heartbeat detection restricts the efficiency of high-availability clusters. Heartbeat packets will be delayed or even lost in the case of system or network overload, leading to the lack of real-time detection, the increased misjudgment rate, and reducing the reliability of the system. Aiming at the issue, this paper presented a new real-time heartbeat mechanism. By controlling the time of sending heartbeat packets, real-time Ethernet TTEP avoids the network delay and collision, which will spe

Abstract:

Ion channels are often found arranged into dense clusters in the plasma membranes of excitable cells, but the mechanisms underlying the formation and maintenance of these functional aggregates are unknown. Here, we tested the hypothesis that channel clustering is the consequence of a stochastic self-assembly process and propose a model by which channel clusters are formed and regulated in size. Our hypothesis is based on statistical analyses of the size distributions of the channel clusters we measured in neurons, ventricular myocytes, arterial smooth muscle, and heterologous cells, which in a

Abstract:

Cluster synchronization is a state where clusters of nodes inside the network exhibit isochronous synchronization. Here, we present a mechanism to realize the strong cluster synchronization in semiconductor laser (SL) networks with complex topology, where stable cluster synchronization is achieved with decreased correlation between dynamics of different clusters and time delay signature concealment. We elucidate that, with the removal of intra-coupling within clusters, the stability of cluster synchronization could be enhanced effectively, while the statistical correlation among dynamics of ea
