Based on symbiosis theory and principle of system engineering, this paper discussed the symbiosis unit, symbiosis mode and symbiotic environment of industral clusters, built a system engineering model called "cluster and symbiosis degree model" which could be used to evaluate the symbiosis situation between two industral clusters, and carried out an empirical analysis for the symbiosis situation between venture capital industrial cluster and high-tech industrial cluster of Beijing, Shanghai anddoi:10.1016/j.sepro.2011.11.090 fatcat:37jaz33eercffh3vl67uegqxsy

The result shows that the symbiosis situation of Shenzhen's venture capital industrial cluster and high-tech industrial cluster is much better than that of Beijing and Shanghai. This model could be used to evaluate the symbiosis situation of any industrial clusters, which will have important theoretical and practical value to any industrial system.
Protein self-assembly and formation of amyloid fibers is an early event of numerous human diseases. Continuous aggregation of amyloid fibers in vitro produces biogels, which led us to suspect that amyloid plaques and neurofibrillary tangles in Alzheimer's disease are of biogels in nature. We applied atomic force microscopy, size exclusion chromatography, and differential scanning calorimetry to elucidate the gel's structure, kinetics of gel formation, and melting point. We found that (1)doi:10.3390/biom9060210 pmid:31151252 pmcid:PMC6628346 fatcat:aimmk4qzunf4zdqcxwsy5q2n3e

The potential role of the gels formed by amyloid fibers in amyloidosis, particularly in Alzheimer's disease was thoroughly discussed, as gels with increased viscosity, are known to restrict bulk flow and then circulation of ions and molecules.
Heterogeneous network (HetNet) has been proposed as a promising solution for handling the wireless traffic explosion in future fifth-generation (5G) system. In this paper, a joint subchannel and power allocation problem is formulated for HetNets to maximize the energy efficiency (EE). By decomposing the original problem into a classification subproblem and a regression subproblem, a convolutional neural network (CNN) based approach is developed to obtain the decisions on subchannel and powerarXiv:1903.00165v1 fatcat:wofr6n2yyfaq3mcjid7kezey7q

This paper considers stochastic hybrid stress quadrilateral finite element analysis of plane elasticity equations with stochastic Young's modulus and stochastic loads. Firstly, we apply Karhunen-Loève expansion to stochastic Young's modulus and stochastic loads so as to turn the original problem into a system containing a finite number of deterministic parameters. Then we deal with the stochastic field and the space field by k-version/p-version finite element methods and a hybrid stressarXiv:1502.06065v1 fatcat:wnlsp2knbbfbrb5oznyjpiodti

This paper examines the initial-value problem for the two-dimensional magnetohydrodynamic equation with only magnetic diffusion (without velocity dissipation). Whether or not its classical solutions develop finite time singularities is a difficult problem and remains open. This paper establishes two main results. The first result features a regularity criterion in terms of the magnetic field. This criterion comes naturally from our approach to obtain a global bound for the vorticity. Due to thedoi:10.1088/0951-7715/28/11/3935 fatcat:n7h35vcuqncnzeoislzhapz3em

Instead we derive and involve a new equation for the combined quantity of the vorticity and a singular integral operator on the tensor product of the magnetic field. This criterion may be verifiable. Our second main result is a weaker version of the small data global existence result, which is shown by the bootstrap argument.
