All-perovskite tandem solar cells have the potential to surpass the theoretical efficiency limit of single junction solar cells by reducing thermalization ***,the challenges encompass the oxidation of Sn^(2+)to Sn^(4+)and uncontrolled crystallization kinetics in Sn-Pb perovskites,leading to nonradiative recombination and compositional heterogeneity to decrease photovoltaic efficiency and operational ***,we introduced an ionic liquid additive,1-ethyl-3-methylimidazolium iodide (EMIMI) into Sn-Pb perovskite precursor to form low-dimensional Sn-rich/pure-Sn perovskites at grain boundaries,which mitigates oxidation of Sn^(2+)to Sn^(4+)and regulates the film-forming dynamics of Sn/Pb-based perovskite *** optimized single-junction Sn-Pb perovskite devices incorporating EMIMI achieved a high efficiency of 22.87%.Furthermore,combined with wide-bandgap perovskite sub-cells in tandem device,we demonstrate 2-terminal all-perovskite tandem solar cells with a power conversion efficiency of 28.34%,achieving improved operational stability.

AIM: To study the changes of the resting state functional connectivity(rsFC) between acute eye pain(EP) subjects and healthy controls(HCs) in the two hemispheres by using voxel-mirrored homotopic connectivity(VMHC) ***: Totally 20 patients with EP and 20 HCs were enrolled, sex, age, and education were matched, and all subjects were examined by functional magnetic resonance imaging(fMRI) scans at resting-state. The changes of rs FC between the hemispheres were evaluated by the VMHC method according to Gaussian random field(GRF) theory. In order to identify the VMHC, as biomarkers for distinguishing EP and from HC, the receiver operating characteristic curves(ROC) had been analyzed. The relationships were evaluated with Pearson correlation analysis between the mean VMHC signal values and clinical features in these ***: By comparing with health subjects, the significant decreased VMHC values was observed in lingual/calcarine(Brodmann area, BA 30), precentral/postcentral gyrus(PreCG/PosCG; BA 4) and medial frontal gyrus(MFG; BA 8)(false discovery rate corrected minary evidence of disrupted interhemispheric rsFC in acute EP in sensorimotor and limbic system and somatosensory cortex, which might give some useful information for understanding the neurological mechanisms in acute EP individuals.

Repetitive control, which adds a human-like learning capability to a control system, is widely used in many fields. This paper deals with the problem of designing a robust repetitive-control system based on output feedback for a class of plants with time-varying structured uncertainties. A continuous-discrete two-dimensional hybrid model is established that accurately describes the features of repetitive control so as to enable independent adjustment of the control and learning actions. A sufficient condition for the robust stability of the repetitivecontrol system is given in terms of a linear matrix inequality. The condition is then used to obtain the parameters of the repetitive controller. Finally, a numerical example demonstrates the effectiveness of the method.

泰国瑶族源自五岭地区的湖南、广西、广东,在脱离母体后,泰国瑶语发生了变化。在词汇构成方面,两地瑶语的差异主要体现在:泰国瑶语较多地保留了民族固有词和文化习俗词,而国内瑶语有些固有词已不见于口语,仅存留在歌谣里,大量的文化习俗词也逐渐消失;泰国瑶语中的借词除共有的老汉语借词外,还有泰语以及其他东南亚语言借词,国内瑶语则限于汉语西南官话借词;泰国瑶语新词的借用方式倾向于半音译半意译,国内瑶语则更多地直接搬用;泰国瑶语有一些新创词,创词方式也多用固有词素和语序,国内瑶语则很少有新创词。

氧化应激及其所致的组织损伤与许多疾病的发生发展过程关系密切。脂氧合酶是一种多功能氧化酶,能参与多种内源性化学物和药物、环境污染物等外源化学物的氧化代谢,并在氧化反应过程中通过多种方式产生活性氧。脂氧合酶能催化内源性化学物如花生四烯酸的反应并伴有活性氧的产生,脂氧合酶还能通过影响细胞间的信号转导而激活其他活性氧产生途径;此外,脂氧合酶还能催化外源化学物代谢为高活性的自由基中间体而诱发活性氧的产生。这些过程中产生的活性氧超过抗氧化系统的清除能力时可导致机体氧化抗氧化系统的失衡而诱发氧化应激,这可能是这些化学物发挥毒性作用的重要机制之一。
