Solid-state intramolecular motions in continuous fibers driven by ambient humidity for fluorescent sensors

One striking feature of molecular rotors is their ability to change conformation with detectable optical signals through molecular motion when stimulated. However, due to the strong intermolecular interactions, synthetic molecular rotors have often relied on fluid environments. Here, we take advantage of the solid-state intramolecular motion of aggregation-induced emission (AIE) molecular rotors and one-dimensional fibers, developing highly sensitive optical fiber sensors that respond to ambient humidity rapidly and reversibly with observable chromatic fluorescence change. Moisture environments induce the swelling of the polymer fibers, activating intramolecular motions of AIE molecules to result in red-shifted fluorescence and linear response to ambient humidity. In this case, polymer fiber provides a process-friendly architecture and a physically tunable medium for the embedded AIE molecules to manipulate their fluorescence response characteristics. Assembly of sensor fibers could be built into hierarchical structures, which are adaptive to diverse-configuration for spatial-temporal humidity mapping, and suitable for device integration to build light-emitting sensors as well as touchless positioning interfaces for intelligence systems.     

高职院校二级学院学生党员发展工作的问题与对策

基于样条逼近分段线性Hammerstein模型的辨识方法

对分段线性Hammerstein系统,讨论了一种样条逼近重构中间输入的信号还原和处理辨识方法。采用三阶B样条近似逼近H模型的非线性输出,线性部分的参数以及样条近似的系数用最小二乘法辨识得到,再结合样条近似结果,利用重构后的多项式回归估计出非线性部分的参数。数字仿真结果表明了该方法的有效性和实用性。     

A virtual learning environment for the continuation of education and its relationship with the mental well-being of chronically ill adolescents

Research has shown that the continuation of education by chronically ill adolescents is an important way to avoid social isolation, psychosocial problems and the accumulation of learning difficulties. In this light, virtual learning environments (VLEs), which connect sick adolescents to their schools, play an important role in ensuring that the sick adolescents continue their education, and in contributing to their mental well-being. This study investigated the extent to which a VLE supports the continuation of education and school interactions among sick adolescents and how it is related to their mental well-being. The results show that the VLE had a positive impact on supporting the continuation of education and school interactions among chronically sick adolescents and was considered very helpful to their mental well-being.     

电大教学模式推广中的概率问题思考

教学模式改革的重要意义,就是将在实践中形成的好的教学模式在更大范围内推广。由于人们在实践中常常移植教学模式的结构和程序,而不同对象的情况千差万别,其结果是在某地有效的教学模式到另一地就可能失效。为此,本文引入概率论的观点,对教学模式进行审视,并以此为基础分析电大教学模式推广中成功的可能性。     

协奏曲的钢琴改编谱演奏初探

在演奏管弦乐队协奏曲总谱改编的钢琴谱时,应当具备对文本（乐谱）的分析能力。而当以钢琴替代乐队时,钢琴协奏者实际上就承担着双重的责任：演奏者、指挥者。对此,钢琴协奏者必须有明确的认识,建立起积极而非被动的协作意识。具备理性的分析和认识是第一步,但毕竟协奏曲钢琴部分的演奏与钢琴独奏有相当明显的区别,因此,在演奏理念和演奏技巧上也要作相应的调节。     

个人专题口语语料库在英语口语教学中的优势

口语语料库的出现为英语口语教学提供了一种崭新的辅助手段,但通用口语语料库由于自身可及性和数据冗余等原因难以和口语教学实践相结合。本文从语境的角度探讨个人专题口语语料库的优势,指出这种小型教学语料库比通用口语语料库更容易融入日常口语教学工作。     

科技术语属性抽取方法研究*

使用共现分析的方法从术语定义抽取术语属性，然后使用对应分析的方法对科技术语和术语属性之间的关系进行分析，并使用图形作为表达方式。最后利用市场营销学科领域的科技文献进行实证研究，对市场营销的概念进行深入挖掘，发现市场营销领域学科研究重点和研究内容等有价值的信息。
