High-rate metal-free MXene microsupercapacitors on paper substrates

MXene is a promising energy storage material for miniaturized microbatteries and microsupercapacitors(MSCs).Despite its superior electrochemical performance,only a few studies have reported MXene-based ultrahigh-rate(>1000 mV s^(−1))on-paper MSCs,mainly due to the reduced electrical conductance of MXene films deposited on paper.Herein,ultrahigh-rate metal-free on-paper MSCs based on heterogeneous MXene/poly(3,4-ethylenedioxythiophene)-poly(styrenesulfonate)(PEDOT:PSS)-stack electrodes are fabricated through the combination of direct ink writing and femtosecond laser scribing.With a footprint area of only 20 mm^(2),the on-paper MSCs exhibit excellent high-rate capacitive behavior with an areal capacitance of 5.7 mF cm^(−2)and long cycle life(>95%capacitance retention after 10,000 cycles)at a high scan rate of 1000 mV s^(−1),outperforming most of the present on-paper MSCs.Furthermore,the heterogeneous MXene/PEDOT:PSS electrodes can interconnect individual MSCs into metal-free on-paper MSC arrays,which can also be simultaneously charged/discharged at 1000 mV s^(−1),showing scalable capacitive performance.The heterogeneous MXene/PEDOT:PSS stacks are a promising electrode structure for on-paper MSCs to serve as ultrafast miniaturized energy storage components for emerging paper electronics.

Security Threats to Business Information Systems Using NFC Read/Write Mode

Radio Frequency IDentification(RFID)and related technologies such as Near Field Communication(NFC)are becoming essential in industrial contexts thanks to their ability to perform contactless data exchange,either device-to-device or tag-to-device.One of the three main operation modes of NFC,called read/write mode,makes use of the latter type of interaction.It is extensively used in business information systems that make use of NFC tags to provide the end-user with augmented information in one of several available NFC data exchange formats,such as plain text,simple URLs or enriched URLs.Using a wide variety of physical form factors,NFC-compatible tags(wireless transponders)are currently available in many locations with applications going from smart posters,contactless tokens,tap-and-go payments or transport ticketing to automated device configuration,patient identification at hospitals or inventory management within supply chains.Most of these applications handle sensitive processes or data.This paper proposes a complete security threat model for the read/write operation mode of NFC used in Next Generation Industrial IoT(Nx-IIoT)contexts.This model,based on a wellknown methodology,STRIDE,allows developers and users to identify NFC applications vulnerabilities or weaknesses,analyze potential threats,propose risk management strategies,and design mitigation mechanisms to mention only some significant examples.

An Investigation on Writing Strategies in EFL Writing: A Case Study of Two Proficient Readers and Two Less Proficient Readers

This paper used case study to investigates the relationship between EFL Reading and EFL Writing in terms of differences in writing strategies with the goal of throwing some light into the flied that has been relatively untouched.Data were collected from think-aloud protocols of four Chinese undergraduate university students,two proficient readers and two less proficient readers.They first took an English Reading Comprehension Test and English Writing Test to evaluate their reading and writing perfor?mance.Then they were trained to think-aloud in the composing process.Subsequently,they did think aloud as they wrote another essay.The major finding of the study consists with the evidences of other studies that reading and writing are interrelated.And fur?ther revealed that reading influence application of writing strategies and writing performance,which provide pedagogical implica?tion for EFL researchers and educators.

A DISCUSSION OF THE RELATIONSHIP BETWEEN READING RATE AND COMPREHENTION

Reading is really a complex of skills and not a single one. It is very popular these days to try to improve reading skills. One sees many essays m newspapers and elsewhere for courses, materias and equipment designed to improve reading rate and comprehension. Most often the emphasis is on reading rate, not on specific comprehention skills. Most of the time is also spent on increasing reading rate, not on good comprehension. I consider neither of them should be overmphasized at the expense of the other.

On the Application of Reading-to-Write Approach to English Writing Teaching in Senior Middle School

As one of the four basic skills of language teaching and an aspect of communicative competence,writing seems to be the weakest one among senior school students in China.Most of teachers have had such experiences that although we spend a lot of time marking on the students'writing,but only to find the corrections and comments ignored.The students pay little attention to responses and regard revision of their writing as a punishment.Starting from the perspectives of modern linguistic theory,the pressing demands of the new curriculum,and the practical needs of student development,the study analyses the prevalent misconceptions about writing.The author proposes an assumption of integrating the teaching materials with Reading-to-Write Approach in the senior school writing teaching.To examine the validity of the Approach,about one-year action research is carried out in an ordinary high school,adopting the methodology of literature survey,questionnaire survey,interview,testing and so on.The results of the experiment showed that the approach had a more positive impact on students'writing attitudes and habits than traditional teaching methods.This approach helped them much more in word usage,longer sentences,content,and text structure or development.Besides,the students'compe?tence of interaction and cooperation were enhanced,Therefore,the approach in writing teaching is effective.

融合文学与编辑出版学的书评写作课程实践教学探析——基于“人文阅读与书评写作”课程的研究

书评写作不仅是帮助学生提升写作能力的方法之一,还是引导学生进行学术研究入门的切实可行的方式,是进行阅读推广与校园文化建设的重要途径。在当下的汉语言文学专业课程体系中,专门性的书评写作课程相对缺失。在教学内容与教学方法方面融合文学与编辑出版学,是书评写作教学值得探索的途径之一。这种探索,还需要拓展教学内容,及时吸纳“文学生活”研究、“出版评论”研究等学科新知;创新写作实训方式,引导学生走进出版业界与社会性阅读空间;深化书评研究,推动其为文学研究做出学术贡献。

读后续写任务提示条件对写作表现和评分信度的影响

读后续写任务将语言理解和产出紧密结合,通过互动协同促进语言习得,具有积极的促学效果。然而,当读后续写应用于大规模考试,则需要考虑任务设计,在保障考试信效度和发挥积极促学作用之间寻求最佳平衡。本研究聚焦读后续写任务中的提示条件,采用实证研究方法考察不同提示条件如何影响学生的写作表现和评分员的评分信度。结果发现,适度的内容提示能够减轻学习者的认知负担,有助于他们创造内容,产出整体质量更高的续作;同时,适度的内容提示也能帮助评分员更一致地把握内容维度的评分尺度,保障评分信度。研究发现对读后续写命题和评分具有重要的启示意义。

基于整本书阅读的辩论训练与过程评价对高中生议论文写作的影响

提升学生的议论文写作水平是高中语文教学的重点和难点。但仅仅依靠课文学习讲解或泛泛地开展整本书阅读,并不能有效提升高中生的议论文写作水平。为探索提升高中生议论文写作水平的有效方法,在一所普通高中实施一项为期14天的基于整本书阅读的辩论训练与过程评价实验。实验对象为该校高一和高二年级的45名学生志愿者。他们被分成6个小组,每组匹配1名导师,阅读材料包括《巴黎圣母院》《围城》《边城》等14本文学名著。实验结果表明,在整本书阅读后增加辩论训练和过程评价,可以非常显著地提升学生的议论文写作水平,具体表现在文章立意、论据选择和论证过程等方面。这些进步可能得益于本实验提升了学生的信息提取、事实判断、整合诠释、逻辑推理,以及分析性思维和批判性思维等高阶思维水平。因此,要提升高中生的议论文写作水平,将整本书阅读与辩论训练和过程评价整合在一起是一个值得尝试的办法。

新高考背景下高中英语读后续写教学策略探究

读后续写这一题型将阅读理解和写作练习结合,对英语教学具有正向的反拨作用。作为高考英语新题型,大多数英语教师对其认知仍不够深入,在教学策略方面处于初步探索的状态,因而导致教学中存在诸多问题。鉴于此,分析读后续写题型的特点及其理论依据,讨论目前读写教学存在的问题,在此基础上,从续写材料的选择、续写思维的培养、语言模仿能力的提高、课堂评价方式的转变四个方面出发,探究读后续写的教学策略,以期为一线高中英语教师的读写教学提供参考。

On Efficient Reading

Time is limited for each reader,but many readers waste a lot oftime on unimportant things, and they read everything at the same speed and in the same way. As a result, they often fail to understand the word and the sentence; they don't know how one sentence relates to another, and how the whole text fixes together. They are not reading efficiently. It is high time that we held a discussion on efficient reading. The author states that efficient reading involves adequate comprehension with appropriate reading rate. Pointing out the factors that influence reading rate and comprehension, this article put forward some suggestions on efficient reading.

基于自我调节学习理论的语文读写一体化模式建构与实证研究

在《义务教育语文课程标准(2022年版)》颁布的背景下,针对语文课堂存在的读写分离、被动学习、整体意识缺乏等问题,构建符合新理念的语文课堂以发展学生语文核心素养,正成为语文教学改革的重要议题。自我调节学习作为一套包含理念、过程和策略的系统性方法,能为读写一体化教学提供新的思路。基于自我调节学习理论的读写一体化教学模式包括四个核心阶段,即明确核心知识与学习目标、整合学习内容与学习资源、创设学习情境与真实问题、形成结构化的学习任务群。以初中语文现代诗歌为主题的应用案例和实证分析,展现了该模式的具体路径,验证了其提高学生读写能力和自主学习能力的有效性。

面向大规模集群作业并发规模的数据库连接池优化技术

数据库作为地震勘探处理软件系统的多学科数据存储管理的核心组件,在底层支撑着处理作业的读写访问需求。在当前,随着地震勘探处理技术的飞速发展,大规模集群下处理作业的并发规模也快速扩张,底层数据库采用常规的读写一体化部署方式难以支撑大规模并发作业的读写请求。笔者针对地震勘探大规模集群数据资料处理作业并发场景,提出一种“1+N”读写分离部署方式的数据库连接池优化技术,设计了基于数据库服务器节点信息的资源分配器,对并发作业的数据库读写请求进行了合理的优化,并在实验室环境和实际地震勘探数据资料处理生产中进行了验证,能够支撑大规模集群下处理作业长事物、高并发等特征的数据库访问请求。
