Developing a plant microbial fuel cell by planting water spinach in a hanging-submerged plant pot system.

To plant crops (especially dry crops such as water spinach) with concomitant electricity recovery, a hanging-submerged-plant-pot system (HSPP) is developed. The HSPP consists of a soil pot (anodic) partially submerged under the water surface of a cathode tank. The microbial communities changed with conditions were also investigated.

How does artificial intelligence empower EFL teaching and learning nowadays? A review on artificial intelligence in the EFL context.

The booming Artificial Intelligence (AI) provides fertile ground for AI in education. So far, few reviews have been deployed to explore how AI empowers English as Foreign Language (EFL) teaching and learning. This study attempts to give a brief yet profound overview of AI in the EFL context by summarizing and delineating six dominant forms of AI application, including Automatic Evaluation Systems, Neural Machine Translation Tools, Intelligent Tutoring Systems (ITSs), AI Chatting Robots, Intelligent Virtual Environment, and Affective Computing (AC) in ITSs.

Understanding, Investigating, and promoting deep learning in language education: A survey on chinese college students' deep learning in the online EFL teaching context.

This study aims to (1) develop and validate the four-dimension model hypothesis of deep learning to better understand deep learning in language education; (2) investigate and promote deep learning by conducting a survey involving 533 college students in the online learning English as a foreign language (EFL) teaching context in China. Concretely, this study initially synthesized theoretical insights from deep learning in the education domain and related theories in the second language acquisition and thus proposed the four-dimension model hypothesis of deep learning involving the motivation of deep learning, the engagement of deep learning, the strategy of deep learning, and the directional competence of deep learning. This study subsequently undertook a questionnaire survey utilizing a standardized instrument to confirm the model hypothesis and further investigate the current status and salient differences in students' deep learning in online EFL teaching.

Microscopic Afterglow Bioimaging by Ultralong Organic Phosphorescent Nanoparticles in Living Cells and Zebrafish.

Compared with short-lived emission probes featuring fluorescence imaging , the use of phosphorescent probes imparts the advantage of long-lived signal persistence that distinguishes against background fluorescence interference. However, the realization of ultralong organic phosphorescent (UOP) probes with an ultralong emission lifetime in an aqueous medium is still a challenge. Here, we present a rational strategy for obtaining UOP nanoparticles (NPs) in an air-saturated aqueous medium prepared using an organic phosphor (PDBCz) and a surfactant polymer (PVP), named PDBCz@PVP, showing an ultralong emission lifetime of 284.

Optimal Design of Hierarchical Cloud-Fog&Edge Computing Networks with Caching.

This paper investigates the optimal design of a hierarchical cloud-fog&edge computing (FEC) network, which consists of three tiers, i.e., the cloud tier, the fog&edge tier, and the device tier.
