| 1 | Bloody Mahjong playing strategy based on the integration of deep learning and XGBoost显示文摘Bloody Mahjong is a kind of mahjong.It is very popular in China in recent years.It not only has the characteristics of mahjong's conventional state space,huge hidden information,complicated rules,and large randomness of hand cards but also has special rules such as Change three,Hu must lack at least one suit,and Continue playing after Hu.These rules increase the difficulty of research.These special rules are used as the input of the deep learning DenseNet model.DenseNet is used to extract the Mahjong situation features.The learned features are used as the input of the classification algorithm XGBoost,and then the XGBoost algorithm is used to derive the card strategy.Experiments show that the fusion model of deep learning and XGBoost proposed in this paper has higher accuracy than the single model using only one of them in the case of highdimensional sparse features.In the case of fewer training rounds,accuracy of the model can still reach 83%.In the games against real people,it plays like human. | Shijing Gao Shuqin Li | 2022 | CAAI Transactions on Intelligence Technology2022，7，1： | 2 |
| 2 | Dry eye disease due to meibomian gland dysfunction treated with Pinggan Yuyin Qingre formula(平肝育阴清热方):a stratified randomized controlled trial显示文摘OBJECTIVE:To observe the clinical efficacy on improving the quality of meibum in patients suffer from dry eye disease(DED)due to meibomian gland dysfunction(MGD)with hyperactivity of Yang due to Yin deficiency pattern after being treated with Pinggan Yuyin Qingre formula(平肝育阴清热方,PGYYQR).METHODS:Totally 120 patients who met the inclusion criteria were included and stratified into three levels according to the level of MGD(1-3),and patients in each level was randomly allocated into the treatment group and control group according to a 1∶1 ratio.Both groups were treated with sodium hyaluronate eye drops,and the treatment group was also given PGYYQR granules.Both groups were treated continuously for eight weeks.The score of the properties of meibomian gland(MG)secretion,the score of the palpebral margins,the average noninvasive tear breakup time(NITBUTav),lipid layer thickness(LLT),and Traditional Chinese Medicine(TCM)syndrome efficacy were compared between the two groups after treatment.RESULTS:A total of 116 cases were included in the statistical analysis.The differences were statistically significant in the score of the properties of MG secretion,the score of the palpebral margins,and NITBUTav between the two groups after treatment,the treatment group was superior to the control group;there was no evidence of a difference in LLT.In terms of TCM syndrome efficacy,the total effective rate was 84.7%in the treatment group and 50.9%in the control group,with the statistically significant difference.None of the included cases had adverse reactions.CONCLUSIONS:PGYYQR is effective in improving the quality of meibum,and the tear film stability which thereby relieving the ocular symptoms in MGD-related DED patients with hyperactivity of Yang due to Yin deficiency pattern. | GAO Yinli LIAN Haihong DENG Shijing DUAN Ying ZHANG Peng WANG Zhiqun ZHANG Yang | 2023 | Journal of Traditional Chinese Medicine2023，43，4： | 1 |
| 3 | Indentation behavior of a semi-infinite piezoelectric semiconductor under a rigid flat-ended cylindrical indenter显示文摘This paper theoretically studies the axisymmetric frictionless indentation of a transversely isotropic piezoelectric semiconductor(PSC)half-space subject to a rigid flatended cylindrical indenter.The contact area and other surface of the PSC half-space are assumed to be electrically insulating.By the Hankel integral transformation,the problem is reduced to the Fredholm integral equation of the second kind.This equation is solved numerically to obtain the indentation behaviors of the PSC half-space,mainly including the indentation force-depth relation and the electric potential-depth relation.The results show that the effect of the semiconductor property on the indentation responses is limited within a certain range of variation of the steady carrier concentration.The dependence of indentation behavior on material properties is also analyzed by two different kinds of PSCs.Finite element simulations are conducted to verify the results calculated by the integral equation technique,and good agreement is demonstrated. | Shijing GAO Lele ZHANG Jinxi LIU Guoquan NIE Weiqiu CHEN | 2024 | Applied Mathematics and Mechanics(English Edition)2024，45，4： | 0 |
| 4 | Hydrothermal sedimentation and superlarge ore deposit显示文摘HYDROTHERMAL fluids, circulated under earth surface, yielded infilling, replacement and thermal dynamic process when ascended near basin basement and resulted in sedimentation when vented into basin, anddeposited pure massive sulfide, chert, feldspar, barite, carbonate and tourmaline rocks with specialstructures, such as massive, laminated, banded, brecciated, stockwork, veinlet and vein which weredistributed in a zonation in space. Sometimes the hydrothermal sediments are mainly composed of microbios. The various types of hydrothermal sedimentary deposits are developed very well in several stages ofgeological history in China. This note will mainly discuss the hydrothermal sedimentary mineralization andthe formation of superlarge ore deposits in four metallogenic belts in China: Devonian belt in QinlingMountains; Sinian belt in South China; Middle Proterozoic belt in Inner Mongolia; Permian belt in SouthChina. 1 Devonian metallogenic belt in Qinling | CHEN Xianpei~1, CHEN Doufu~1, GAO Jiyuan~1, PAN Jingming~1, CHEN Guangqian~1, QI Shijing~2 and LI Ying~2 1.
