学界对于《国家通用语言文字法》修改的研究,从注重国家通用语言文字的标准化,发展到重视语言权的保护,再发展到强调国家通用语言文字的认同作用,形成了朝着铸牢中华民族共同体意识的方向发展的修法共识。从国家认同语境看,《国家通用语言文字法》的修改应从处理好国家通用语言文字与少数民族语言文字的关系入手,着重解决以下问题:国家通用语言文字在法律上应该具有何种地位?少数民族语言文字应该如何学习和使用?对于某些特殊群体,国家通用语言文字水平是否应该有硬性要求?作为国家通用语言文字教育的主阵地,学校应该做什么?参考近年来国家层面的语言文字政策和地方性法规规章内容,建议:确认国家通用语言文字的主体地位,明确少数民族语言文字使用的具体情形,规定国家机关、教育机构和其他公共服务行业工作人员的语言资质条件,配齐少数民族学校教授国家通用语言文字的教材、师资和设备,真正让这部法律成为国家通用语言文字保护和传承的根基。

Ovarian endometrioma（OE）, also known as “chocolate cysts,” is a cystic mass that develops in the ovaries due to endometriosis and is a common gynecological condition characterized by the growth of endometrial tissue outside the uterus, leading to symptoms such as dysmenorrhea, pelvic pain, and infertility. However, the precise molecular and cellular mechanisms driving this pathophysiology remain largely unknown, posing challenges for diagnosis and treatment. Here, we employed integrated single-cell transcriptomic profiling of over 52,000 individual cells from endometrial tissues of OE patients and healthy donors and identified twelve major cell populations. We identified notable alterations in cell type-specific proportions and molecular signatures associated with OE. Notably, the activation of IGFBP5+macrophages with pro-inflammatory properties, NK cell exhaustion, and aberrant proliferation of IQCG+and KLF2+epithelium are key features and may be the potential mechanisms underlying the pathogenesis of OE. Collectively, our data contribute to a better understanding of OE at the single cell level and may pave the way for the development of novel therapeutic strategies.

This paper designs distributed Nash equilibrium seeking strategies for heterogeneous dynamic cyber-physical *** particular, we are concerned with parametric uncertainties in the control channel of the players. Moreover, the weights on communication links can be compromised by time-varying uncertainties, which can result from possibly malicious attacks,faults and disturbances. To deal with the unavailability of measurement of optimization errors, an output observer is constructed,based on which adaptive laws are designed to compensate for physical uncertainties. With adaptive laws, a new distributed Nash equilibrium seeking strategy is designed by further integrating consensus protocols and gradient search ***, to further accommodate compromised communication weights resulting from cyber-uncertainties, the coupling strengths of the consensus module are designed to be adaptive. As a byproduct, the coupling strengths are independent of any global information. With theoretical investigations, it is proven that the proposed strategies are resilient to these uncertainties and players' actions are convergent to the Nash equilibrium. Simulation examples are given to numerically validate the effectiveness of the proposed strategies.
