This paper consists of two parts. In part I, we interpret the hidden symmetry of the moduli space of lib superstring on AdS5× S^5 in terms of the chiral embedding in AdS5, which turns out to be the CP^3 conformal affine Toda model. We review how the position μ of poles in the Riemann-Hilbert formulation of dressing transformation and the value of loop parameter μ in the vertex operator of affine algebra determine the moduli space of the soliton solutions, which describes the moduli space of the Green-Schwarz superstring. We show also how this affine SU（4） symmetry affinizes the conformal symmetry in the twistor space, and how a soliton string corresponds to a Robinson congruence with twist and dilation spin coefficients μ of twistor. In part Ⅱ by extending the dressing symmetric *** of lib string in AdS5×S^5 to the D3 brane, we find a gauged WZW aztion of Higgs Yang-Mills field including the 2-cocycle of axially anomaly. The left and right twistor structures of left and right a-planes glue into an ambitwistor. The symmetry group of Nahm equations is centrally extended to an affine group, thus we explain why the spectral curve is given by affine Toda.

目的了解本地区育龄妇女支原体感染现状及药敏分析,指导临床合理用药。方法收集2019年1月-10月妇科门诊患者生殖道标本1200份,对标本进行鉴定及药敏检测。结果1200份标本中共检出Uu127份(10.6%),Mh4份(0.3%),Uu+Mh混合感染61份(5.0%)。单纯U u感染的标本中仅对氧氟沙星和四环素耐药率较高,对其他药物敏感性较好。单纯M h感染的标本检出率较低,但是阳性标本的耐药情况要比单纯Uu感染标本强;混合感染标本对阿奇霉素、交沙霉素和氧氟沙星耐药率均为100%,对环丙沙星和四环素耐药率也较高。结论Uu是引起泌尿生殖道感染的主要支原体。单独Uu感染的标本药物耐药率最低;单独M h感染标本虽检出率较低,但是耐药现象较严重;混合感染标本耐药最为严重,治疗药物首选强力霉素、交沙霉素和红霉素,应合理用药避免药物滥用促进耐药发生。

Cs2TiBr6， characterized as a lead-free vacancy-ordered double perovskite material， demonstrates notable stability and photoelectric performance， rendering it suitable for application in perovskite solar cells. However， the experimental efficiency of this material is currently limited， achieving only 3.12%. This efficiency limitation primarily stems from the material’s wide bandgap， which results in insufficient light absorption. To address this issue， this study utilized Cs2PtI6-xBrxfor band structure fine-tuning. By adjusting the bandgap of Cs2PtI6-xBrxthrough Br-doping， not only was the alignment of the energy bandgap in the absorption layer effectively adjusted， but the cutoff range of light absorption was also significantly expanded. Setting the Cs2PtI6-xBrxbandgap to 1.4 eV resulted in optimal device performance. Additionally， comparative analyses aimed at boosting solar cell efficiency were performed on both hole transport and electron transport layer materials. Subsequently， the structure of the perovskite solar cell was optimized using an FTO/TiO2/Cs2TiBr6/Cs2PtI6-xBrx/Cu2O/Au configuration. Furthermore， the influence of the absorber layer thickness and defect density on device performance was studied. Ultimately， this configuration enabled the Cs2TiBr6/Cs2PtI6-xBrxsolar cell to achieve a peak conversion efficiency of 29.69%.
