Abstract: A dynamic network resource allocation method based on network slicing is provided. A historical resource demand dataset of an accessed network slice is inputted into a first neural network for training. Based on a trained first neural network and the historical resource demand of the accessed network slice, a resource demand prediction information corresponding to the accessed network slice in a first prediction time period is determined. Resources are pre-allocated to the accessed network slice based on the resource demand prediction information, and resources are allocated to the accessed network slice when the first prediction time period arrives. In this way, the service provider can reasonably allocate network resources for network slices without violating the SLA, thus avoiding the waste of network resources.

Abstract: Highly porous nucleophilic organic cages (Nu-POC) were in-situ synthesized on cotton fibers by a condensation reaction between cyanuric chloride and melamine, and the products were employed as a robust wearable and flexible detoxifying protective material (denoted as POCotton) for vaporous pesticides. The covalent growth of Nu-POC particles on surfaces of cotton fibers retained the physical characteristics of Nu-POC to the greatest extend, which include specific surface area and porosity, while the cotton fabrics still remained wearable. The resultant POCotton can repeatedly adsorb fumigant vapors instantly (i.e., equilibrium reached within one minute) and massively (i.e., adsorption capacity at 596.88 mg/g of methyl iodide).
