2Association of Sandstone-Type Uranium Mineralization in the Northern China with Tectonic Movements and Hydrocarbons显示文摘In the continental basins of Northern China(NC),a series of energy resources commonly co-exist in the same basin.As the three typical superimposed basins of different genesis in the NC,the Junggar,Ordos,and Songliao basins were chosen as the research objects.The favorable uraniumbearing structures are generally shown as a basin-margin slope or transition belt of uplifts with the development of faults,which are conducive to a fluid circulation system.The Hercynian,Indosinian,and Yanshanian movements resulted in the development of uranium-rich intrusions which acted as the significant uranium sources.The main hydrocarbon source rocks are developed in the Carboniferous,Permian,Jurassic and Cretaceous.The mature stage of source rocks is concentrated in the Jurassic–Cretaceous,followed by the multi-stage expulsion events.Influenced by the India-Eurasian collision and the subduction of the Pacific Plate,the tectonic transformation in the Late Yanshanian and Himalayan periods significantly influenced the sandstone-type uranium mineralization.The hydrocarbon reservoirs are spatially consistent with sandstone-type uranium deposits,while the hydrocarbon expulsion events occur in sequence with sandstone-type uranium mineralization.In the periphery of the faults or the uplifts,both fluids met and formed uranium concentration.The regional tectonic movements motivate the migration of hydrocarbon fluids and uranium mineralization,especially the Himalayan movement.Yin Chen Peisen Miao Jianguo Li Ruoshi Jin Hualei Zhao Lulu Chen CongWang HaoyuYu Xiaoru Zhang 2022Journal of Earth Science2022,33,2:2

4Deterministic learning from control of nonlinear systems with disturbances显示文摘In this paper, we investigate deterministic learning in environments with disturbances. We will show that for a class of uncertain nonlinear systems with bounded disturbances, by using an appropriately designed adaptive neural controller, the disturbances are attenuated and the system output tracks a periodic orbit in finite time. As radial basis function (RBF) neural networks (NN) are employed, this leads to the satisfaction of a partial persistence of the excitation (PE) condition. By using the uniform complete observability (UCO) technique, it is analyzed that partial estimated NN weights will converge to a neighborhood of zero, with the size of the neighborhood depending on the amplitude of disturbances as well as on the control gains. Locally-accurate approximation of unknown system dynamics can still be achieved in the stable NN control process. The approximation error level is influenced by the amplitude of disturbances. The obtained knowledge of system dynamics can be reused in another control process towards stability and improved performance. Simulation studies are included to demonstrate the effectiveness of the approach.Guopeng Zhou CongWang 2009Progress in Natural Science:Materials International2009,19,8:1
5A Green Approach to Producing Polymer Microparticles for Local Sustained Release of Flavopiridol显示文摘Poly(lactic-co-glycolic acid)(PLGA)microparticles represent an important class of materials used for drug delivery.Current synthesis frequently uses conventional emulsion,where dichloromethane(DCM)is used as the organic phase solvent.Due to the health and environmental toxicity of DCM and its slow degradation,this work replaces DCM with a greener solvent,dimethyl carbonate(DMC).Matthew J.OWEN Jasper H.N.YIK Congwang YE Brianca NETTO Dominik R.HAUDENSCHILD Gang-yu LIU 2021Chemical Research in Chinese Universities2021,37,5:0
