| 1 | Personalized Learning Path Recommendations for Software Testing Courses Based on Knowledge Graphs显示文摘Software testing courses are characterized by strong practicality,comprehensiveness,and diversity.Due to the differences among students and the needs to design personalized solutions for their specific requirements,the design of the existing software testing courses fails to meet the demands for personalized learning.Knowledge graphs,with their rich semantics and good visualization effects,have a wide range of applications in the field of education.In response to the current problem of software testing courses which fails to meet the needs for personalized learning,this paper offers a learning path recommendation based on knowledge graphs to provide personalized learning paths for students. | Wei Zheng Ruonan Gu Xiaoxue Wu Lipeng Gao Han Li | 2023 | 计算机教育2023，，12： | 0 |
| 2 | Propofol inhibits cells migration and invasion via HOTAIR/miR-93/HIF-1α-mediated lactate secretion in colon cancer显示文摘Propofol,a common intravenous anesthetic used in clinical,has been shown to regulate cells proliferation,inflammation,angiogenesis and metastasis as well as exerting anti-cancer effect in several different types of cancer.However,the functions and mechanisms of propofol in lactate secretion and invasion of cancer cells remain unknown.The primary aim of this study was to investigate the role of propofol in cells migration and invasion of colon cancer(CRC).Scratches assay,Transwell assay were used to detect colon cells migration and invasion.Realtime Quantitative Polymerase Chain Reaction(RT-qPCR),Western blotting were utilized to detect the expression of related molecules.Dual-luciferase assay was performed to identify transcriptional activity of target genes,RNA pulldown assay was used to confirm the interactions of RNAs.Results indicated that propofol inhibited cell migration and invasion through suppressing lactic acid production in CRC.Moreover,propofol reduced lactic acid production by down-regulating the expression of hypoxia inducible factor-1α(HIF-1α)and monocarboxylate transporter 4(MCT4).In addition,propofol inhibited the expression of HIF-1αand cells migration/invasion via suppressing the interaction of HOX transcript antisense RNA(HOTAIR)with miR-93.The present study indicated that propofol inhibited colon cancer cell migration and invasion by reducing lactic acid production and the expression of HIF-1αand MCT4 via HOTAIR/miR-93 axis.These data may provide potential metabolic targets for CRC treatment. | RUONAN GU WENJING GUO WENYANG WANG GUIHUAN LI XIAOJU LAI ZHIBIN HUANG WANLU ZHAO ZHICONGWU HUA CHEN WENYANG LUO FANGYIN ZENG FAN DENG | 2021 | BIOCELL2021，45，6： | 0 |
| 3 | Micro–Nano Water Film Enabled High‑Performance Interfacial Solar Evaporation显示文摘Interfacial solar evaporation holds great promise to address the freshwater shortage.However,most interfacial solar evaporators are always filled with water throughout the evaporation process,thus bringing unavoidable heat loss.Herein,we propose a novel interfacial evaporation structure based on the micro–nano water film,which demonstrates significantly improved evaporation performance,as experimentally verified by polypyrrole-and polydopamine-coated polydimethylsiloxane sponge.The 2D evaporator based on the as-prepared sponge realizes an enhanced evaporation rate of 2.18 kg m^(−2)h^(−1)under 1 sun by fine-tuning the interfacial micro–nano water film.Then,a homemade device with an enhanced condensation function is engineered for outdoor clean water production.Throughout a continuous test for 40 days,this device demonstrates a high water production rate(WPR)of 15.9–19.4 kg kW^(−1)h^(−1)m^(−2).Based on the outdoor outcomes,we further establish a multi-objective model to assess the global WPR.It is predicted that a 1 m^(2)device can produce at most 7.8 kg of clean water per day,which could meet the daily drinking water needs of 3 people.Finally,this technology could greatly alleviate the current water and energy crisis through further large-scale applications. | Zhen Yu Yuqing Su Ruonan Gu Wei Wu Yangxi Li Shaoan Cheng | 2023 | Nano-Micro Letters2023，15，11： | 0 |
