With the announcement of open information policy by the Chinese government, there has been lots of development in government statistics, Census data, and GIS data. That information provides rich reference for regional analysis in China. The primary challenges under rapid data growth include how to efficiently integrate those space-time data, provide methodology for different research targets, a...

We present a simple model of network dynamics that can be solved analytically for fully connected networks. We obtain the dynamics of response of the system to perturbations. The analytical solution is an excellent approximation for random networks. A comparison with the scale-free network, though qualitatively similar, shows the effect of distinct topology.

The purpose of this study is designing a model based on Tobit regression, DEA, Artificial Neural Network, Genetic Algorithm and Particle Swarm Optimization to evaluate the efficiency and also benchmarking the efficient and inefficient units. This model has three stages, and it uses the data envelopment analysis combined model with neural network, optimized by genetic algorithm, to evaluate the ...

Evaluating sustainability at a regional level requires some assessment of the degree to which conservation and production criteria are integrated so as to provide high present and future net benefits to society. This assessment cannot be achieved simply by using indices based on comparisons for the individual criteria of observed indicator values with standards; not only may objective standards...

Increasing concern over the regional dimensions of national economic planning since 1970s, has constituted appropriate baselines for scientific analysis of regional differences The Iranian planning views in the pre and post revolution era have been examined in this article, based on both theoretical and applied study of regional differences. Then the types and degrees of convergency and/or dive...

Our understanding of how evolution acts on biological networks remains patchy, as is our knowledge of how that action is best identified, modelled and understood. Starting with network structure and the evolution of protein-protein interaction networks, we briefly survey the ways in which network evolution is being addressed in the fields of systems biology, development and ecology. The approac...

The DØ experiment is facing many exciting challenges providing a computing environment for its worldwide collaboration. Transparent access to data for processing and analysis has been enabled through deployment of its SAM system to collaborating sites and additional functionality will be provided soon with SAMGrid components. In order to maximize access to global storage, computational and inte...

East Java's economic recovery due to the Covid-19 pandemic is no better than national recovery. In 2020, growth contracted by 2.33 percent (y-on-y), deeper economy which 2.07 (y-on-y). Moreover, when began recover and grew 3.69 (y-on-y) in 2021, only increased 3.57 These conditions indicate that Java need of appropriate comprehensive policies support acceleration Viewed from high contribution M...

Many natural and artificial two-states signaling devices are connected forming networks. The information-processing potential of these systems is usually related to the response to weak external signals. Here, using a network of overdamped bistable elements, we study the effect of a heterogeneous complex topology on the signal response. The analysis of the problem in random scale-free networks,...
