本文主要探讨了喀麦隆“Bilingual Grammar School Molyko”初级汉语综合课的教学设计与实践。通过对该校汉语学习情况的调查研究,以及对综合课教学设计的深入分析,评估和反思,为喀麦隆中学汉语教学提供理论依据和实践指导。本研究具有重要的学术和实际意义,既丰富了国际汉语教育理论,又为汉语教师在非洲国家的教学实践提供了具体参考。在第二章中,研究对喀麦隆“Bilingual Grammar School Molyko”中学汉语学习情况进行了详尽调查。调查采用问卷、访谈等方法,收集了学生、教师和学校管理者的多维度数据。分析结果显示,该校学生对汉语学习具有较高兴趣,但在学习过程中也面临诸多挑战,如语言环境缺乏、学习资源不足和教学方法单一等问题。这些问题的存在,不仅制约了学生的汉语学习效果,也影响了汉语教学的进一步发展。第三章聚焦于“Bilingual Grammar School Molyko”中学生综合课的教学设计。根据调查结果和教学实践经验,结合汉语国际教育的理论和方法,设计了一套适合喀麦隆中学生的汉语综合课教学方案。该方案从教学目标、课程设置、教学内容、教学方法和评价体系等方面进行了系统规划。教学目标明确,注重听、说、读、写四项技能的全面发展;课程设置合理,既有基础知识的传授,又有文化素养的培养;教学内容丰富,涵盖语言知识、文化知识和交际能力的培养;教学方法多样,采用任务型教学、情景教学等方法,提高学生的学习兴趣和参与度;评价体系完善,既有形成性评价,又有终结性评价,全面监测学生的学习效果。第四章对“Bilingual Grammar School Molyko”初级中文综合课的教学设计进行了评估与反思。评估采用质性和量性相结合的方法,通过课堂观察、学生测试、教师访谈等途径,全面分析了教学设计的实施效果。评估结果表明,该教学设计在提高学生汉语水平和学习兴趣方面取得了一定成效,但也存在一些不足,如教学资源有限、师资力量不足、教学方法需要进一步改进等。基于评估结果,研究提出了一系列改进建议,如增加教学资源投入、加强教师培训、改进教学方法等,为后续的教学实践提供了有益参考。本研究通过对喀麦隆“Bilingual Grammar School Molyko”初级汉语综合课教学设计的调查、分析和反思,不仅丰富了国际汉语教育理论,也为喀麦隆中学汉语教学实践提供了重要参考。研究结果显示,科学合理的教学设计对提高学生汉语学习效果具有重要作用,但同时也需要持续关注和解决实际教学中存在的问题,才能真正实现汉语教育的长远发展。本论文的研究方法具有一定创新性,通过综合运用问卷调查、访谈、课堂观察和教学评估等多种方法,获取了详实的数据,确保了研究结果的可靠性和科学性。研究不仅对喀麦隆汉语教学具有重要指导意义,也对其他非洲国家的汉语教育实践具有参考价值。希望本研究能够为喀麦隆及其他非洲国家的汉语教学提供有益借鉴,推动国际汉语教育事业的发展。

In[***.A 107012427(2023)],Baldwin and Jones prove that Uhlmann–Jozsa’s fidelity between two quantum statesρandσ,i.e.,F(ρ,σ)=(Tr√√ρσ√ρ)^(2),can be written in a simplified form as F(ρ,σ)=(Tr√ρσ)^(2).In this article,we give an alternative proof of this result,using a function power series expansion and the properties of the trace *** approach not only reinforces the validity of the simplified expression but also facilitates the exploration of novel dissimilarity functions for quantum states and more complex trace functions of density operators.

Background: Magnesium, an essential mineral crucial for various bodily functions, has been shown to positively influence sleep patterns. This study aimed to evaluate the efficacy of Food-Grown® magnesium in enhancing sleep quality and duration, as well as overall well-being. Methods: eighty participants were randomly assigned to receive either 80 mg of Food-Grown® magnesium or a placebo (microcrystalline cellulose) daily for 8 weeks. Participants completed questionnaires assessing sleep quality, daytime drowsiness, quality of life, anxiety, and stress levels. Additionally, participants maintained daily sleep diaries and wore wrist-worn actigraphy devices. The primary outcome measured was the change in sleep quality and duration. Results: Seventy-one participants fulfilled all study requirements (35 in the active group and 36 in the placebo group). Magnesium supplementation significantly improved reported sleep quality, with the active group showing a 32% increase compared to 16% in the placebo group (p = 0.034). Moreover, magnesium supplementation led to a decrease in reported stress scores at week 8 compared to the placebo group (3.7 ± 2.6 vs. 5.5 ± 3.1, respectively). Both the magnesium and placebo groups exhibited significant increases in reported sleep duration and reductions in time to fall asleep, sleep disturbance, sleep latency, sleep medication usage, and total Pittsburgh Sleep Quality Index score at week 8 compared to baseline. Conclusion: Magnesium supplementation notably enhanced sleep quality and reduced stress levels compared to the placebo group. These findings highlight the potential of magnesium as a beneficial supplement for improving sleep quality and overall well-being.

This research paper has provided the methodology and design for implementing the hybrid author recommender system using Azure Data Lake Analytics and Power BI. It offers a recommendation for the top 1000 Authors of computer science in different fields of study. The technique used in this paper is handling the inadequate Information for citation;it removes the problem of cold start, which is encountered by very many other recommender systems. In this paper, abstracts, the titles, and the Microsoft academic graphs have been used in coming up with the recommendation list for every document, which is used to combine the content-based approaches and the co-citations. Prioritization and the blending of every technique have been allowed by the tuning system parameters, allowing for the authority in results of recommendation versus the paper novelty. In the end, we do observe that there is a direct correlation between the similarity rankings that have been produced by the system and the scores of the participant. The results coming from the associated scrips of analysis and the user survey have been made available through the recommendation system. Managers must gain the required expertise to fully utilize the benefits that come with business intelligence systems [1]. Data mining has become an important tool for managers that provides insights about their daily operations and leverage the information provided by decision support systems to improve customer relationships [2]. Additionally, managers require business intelligence systems that can rank the output in the order of priority. Ranking algorithm can replace the traditional data mining algorithms that will be discussed in-depth in the literature review [3].

Finding top-k elephant flows in high-speed networks is one of the most fundamental network measurement tasks. It is more challenging than per-flow size estimation since the IDs and sizes of top-k flows must be tracked simultaneously. Most existing studies only record the IDs of a small number of elephant flows to fit their estimators in the extremely limited high-speed on-chip memory. However, these solutions need too many memory accesses when a packet arrives to track the elephant flows with high accuracy, which limits their practicability. Therefore, this paper proposes Jigsaw-Sketch, a new algorithm to find the top-k elephant flows with much fewer memory accesses while achieving high memory efficiency and accuracy. In this design, we propose a novel two-stage jigsaw storage scheme, which can capture the candidate top-k flows from massive network steams efficiently, and further find the top-k elephant flows with high memory efficiency and only a few memory accesses for each packet. extensive experimental results based on real network traces show that Jigsaw-Sketch improves the packet processing throughput by at least 86%, while achieving smaller memory footprints and higher accuracy compared to the SOTA.
