Acta Oceanologica Sinica 2020年第7期39卷 32-41页

the characteristics of the t/S structures,water mass exchange and deep circulation in the Andaman Sea are investigated based on the simulation from a high-resolution general circulation model(MItgcm).the results show that,below 1000 m,the water mass is saltier,warmer and more homogeneous in the Andaman Sea than that in the Bay of Bengal,attributing to the strong vertical mixing at the depth of^1800 *** water mass exchange between the Andaman Sea and the Bay of Bengal goes through three major channels,which manifests itself as follows:the northern channel(Preparis Channel)is the main passage of water mass transport from the Bay of Bengal to the Andaman Sea,whereas the Middle Channel(the south of Andaman Islands and the north of Nicobar Islands)has an opposite transport;the southern channel(Great Channel)features with a four-layer water exchange which results in the least net transport among the three channels;all the transports through the three channels have an intra-annual variation with a period of half a *** 1000-m depth,the entire Andaman Sea is occupied by a cyclonic circulation in January and July while by an anticyclonic one in April and *** semiannual cycle found in both the deep circulation and water mass exchange is likely associated with the downwelling eastward-propagating Kelvin waves induced by the semiannual westerly component in the equatorial Indian Ocean during intermonsoon seasons.

A new optimization method for the optimization of stacking of composite glass fiber laminates is developed. the fiber orientation and angle of the layers of the cylindrical shells are sought considering the buckling load. the proposed optimization algorithm applies both finite element analysis and the mode-pursuing sampling （MPS）method. the algorithms suggest the optimal stacking sequence for achieving the maximal buckling load. the procedure is implemented by integrating ANSYS and MAtLAB. the stacking sequence designing for the symmetric angle-ply three-layered and five-layered composite cylinder shells is presented to illustrate the optimization process, respectively. Compared with the genetic algorithms, the proposed optimization method is much faster and efficient for composite staking sequence plan.

Multi-Objective Optimization for an Industrial Grinding and Classification Process Based on PBM and RSM

引用

IEEE/CAA Journal of Automatica Sinica 2023年第11期10卷 2124-2135页

作者： Xiaoli Wang Luming Liu Lian Duan Qian liao School of Automation Central South universityChangsha 410083China Changsha Research Institute of Mining and Metallurgy Changsha 410012China

the grinding and classification process is one of the key sub-processes in mineral processing, which influences the final process indexes significantly and determines energy and ball consumption of the whole plant. therefore, optimal control of the process has been very important in practice. In order to stabilize the grinding index and improve grinding capacity in the process,a process model based on population balance model(PBM) is calibrated in this study. the correlation between the mill power and the operating variables in the grinding process is modelled by using the response surface method(RSM), which solves the problem where the traditional power modeling method relies on some unobservable mechanism-related parameters. On this basis, a multi-objective optimization model is established to maximize the useful power of the grinding circuit to improve the throughput of the grinding operation and improve the fraction of –0.074 mm particles in the hydrocyclone overflow to smooth the subsequent flotation operation. the elite non-dominated sorting genetic algorithm-II(NSGA-II) is then employed to solve the multi-objective optimization problem. Finally, subjective and objective weighting methods and integrated multi-attribute decision-making methods are used to select the optimal solution on the Pareto optimal solution set. the results demonstrate that the throughput of the mill and the fraction of –0.074 mm particles in the overflow of the cyclone are increased by 3.83 t/h and 2.53%, respectively.

We here report a non-gene therapy anti-tumor nanoparticles(I3C@cLANPs)based PtEN by loading indole-3-methanol(I3C)into the cross-linked lipoic acid nanoparticles(cLANPs)for triple-negative breast cancer(tNBC)treatment.I3C is a PtEN-specific natural activator while the poor PtEN-activation effi-ciency impedes its ability to achieve the PtEN-mediated tumor *** to the structural homology of lipoic acid(LA),the cLANPs hold not only LA-like anticancer activity but also PtEN-activation proper-ties,which would synergistically potentiate the PtEN-activation *** in vitro and in vivo data showed that PtEN expression in the I3C@cLANPs group was 2.1 and 2.8 times higher than that of I3C,*** antitumor evaluation based on the 4t1 tumor-bearing mice showed a tumor inhibitory rate(tIR)of 78.4%at the I3C usage of 20 mg kg^(–1),54.5%higher than that of I3C alone and 19.7%higher than that of first-line chemotherapy drug Doxorubicin hydrochloride(DOX).thus,the I3C@cLANPs could address the low activation efficiency in the PtEN-mediated tumor strategy and avoid the risks of gene therapy,holding a good prospect for tNBC and related cancer treatment.
