Clip Voice: Misogyny and the Renegotiation of a Gendered Vocal Style in Chinese Digital Discourse
Journal of Sociolinguistics, Volume 29, Issue 5, Page 348-359, November 2025.ABSTRACT The participatory culture of social media allows women's voices to be heard but also parodied and policed. On Chinese social media platforms, where performers rapidly adopt and transform vocal trends for engagement, discourse on gendered vocal styles has proliferated.

源荷储多类型灵活性资源协调的高比例可再生能源电源规划 [PDF]
全球能源互联网, 2019 未来高比例可再生能源电力系统愿景下，具有波动性和不确定性的风/光等可再生能源作为主要能源供应者，给电力系统带来了巨大的灵活性需求，考虑单一类型灵活性资源提供调节能力的规划模型和以净负荷包络线为基础的电源规划方法将不再适用。引入灵活性指标量化评估源荷储多类型灵活性资源的调节潜力并作为优化决策变量纳入到规划模型中，从而建立以全周期投资成本最小化为目标的高比例可再生能源电源规划模型。通过电源投资决策、生产模拟和灵活性评估3个流程模块，实现单位投资改善灵活性指标最优的电源规划方案求解。最后 ...

Ultrasound in Obstetrics &Gynecology, Volume 65, Issue 5, Page 624-632, May 2025.ABSTRACT Objectives Placental insufficiency contributes to many obstetric pathologies, but there is no bedside clinical tool to evaluate placental perfusion. We have developed a method to acquire multiple three‐dimensional (3D) power Doppler (PD) ultrasound (US) volumes of placental vasculature, with infrared camera tracking of the precise spatial ...

Methods in Ecology and Evolution, Volume 15, Issue 11, Page 1926-1939, November 2024.Abstract Simulation studies are essential tools to assess statistical methods. Functioning as controlled experiments, simulations generate data from known underlying processes. However, unclear or incomplete reporting of simulation studies can impact their interpretability and reproducibility, potentially leading to the misuse of statistical methods ...

Research on Methods of Modeling and Fault Diagnosis for Micro Direct-Current Motors [PDF]
, 2015 直流微电机以体积小、重量轻、便于控制等优点被广泛应用于生产消费领域，在微型精密仪器中尤为重要。为了保证产品出厂品质，生产过程必须对直流微电机进行100%检测。目前检测主要依靠人工的经验来判断电机的好坏，其工作量大，生产效率低，漏检现象严重，导致电机出厂质量不稳定。因此有必要寻找一种简便和可靠的直流微电机在生产线上的故障检测技术。该技术即可以对出厂前的直流微电机进行自动在线检测，以保证直流微电机的出厂合格率；又可以推广应用于其他永磁直流电机的故障检测与诊断。 通过分析空载下直流电机的动态数学模型 ...
