ABSTRACT Harnessing solar energy for self‐heating presents an effective strategy to suppress surface ice formation. In this paper, we fabricated nano‐silver‐modified multilayer graphene sheets (Ag@MGs) that integrate photothermal and superhydrophobic properties for anti‐icing applications.

ABSTRACT Given the importance of the linguistic landscape in language learning, the digital linguistic landscape (DLL) has emerged as an important multimodal input resource. However, few studies have been conducted to explore the antecedent and predictive effect of the DDL on L2 writing. To address this gap, the study attempted to conceptualize the DLL

US Foreign Policy and the Gulf States: Changing Dynamics in a Multipolar World
ABSTRACT This article focuses on US foreign policy toward the Gulf from Obama's Pivot to Asia to the initial period of the second Trump administration. It situates the role of the US within the broader context of the global energy transition and the Gulf states as geopolitical actors in a multipolar world order.

Joint Extraction Method for Spatial Relations in Chinese Geological Texts
Abstract Extracting spatial relations of geological entities is an important prerequisite for achieving natural language processing tasks such as geological knowledge question answering and semantic search, and is an important means to achieve structural reconstruction of unstructured geological data.

ABSTRACT While previous research has established nominal complexity as a key indicator of grammatical complexity, its multi‐dimensional manifestation in constrained varieties remains underexplored. This study investigates the distribution of complex nominal structures in constrained spoken English varieties, specifically English as a Second Language ...

为了研究低温环境对硅橡胶绝缘材料憎水性的影响,采用恒温试验箱对复合绝缘子用硅橡胶材料进行了低温冷冻处理。利用JC2000DM接触角测量仪测量了硅橡胶试品的静态接触角,得到了不同温度下、不同氢氧化铝含量硅橡胶材料的憎水性随时间变化的规律,并分析了硅橡胶憎水性变化的原因机理。实验结果表明:随着低温处理时间的延长,硅橡胶材料的静态接触角呈现出先增大后趋于稳定的特性,不同温度条件下硅橡胶材料憎水角趋于稳定所需的时间不同,温度越低,静态接触角增大到趋于稳定的时间越短;在同一低温处理下 ...

Research on digital discretion—The subjectification of street‐level work in public administration
Abstract The article presents a systematic review of scholarly articles (n = 168) focused on digital discretion—how digital technologies affect the discretionary autonomy of street‐level bureaucrats. Two analytical tasks are performed concerning how digital transformation has affected (1) the relations between top‐down governing and the work of street ...

分别研究了不同水滴体积和测量时间、喷雾次数及静置时间对聚烯烃材料表面静态接触角和HC分级的影响,并通过使用不同目数的砂纸打磨聚烯烃材料表面,研究表面粗糙度对其憎水性能的影响。结果表明:进行聚烯烃材料的憎水性试验时,采用4μL~8μL的水滴在10 s~40 s内测量其静态接触角较为准确,θs值随时间变化较小,水滴边缘接近圆形。喷雾20次~30次,在30 s内完成HC分级图像的采集较能准确评估聚烯烃材料的HC分级特性。随着表面粗糙度的增大,打磨聚烯烃材料的静态接触角平均值呈现震荡上升的变化趋势 ...

Return from exile: Mythology and heritage in American Born Chinese and its Disney adaptation
Abstract Though American Born Chinese has received a significant degree of scholarly study, the prevalence of cultural exile in the text has not received sufficient attention. Said's theorization on exile provides a guide to examining the mindset of Jin, who willfully accepts exile from his Chinese‐American heritage because of how he feels neither ...
