Feynman Path Integral Using Operator Integration in Banach Space
2024年
Feynman-Path Integral in Banach Space: In 1940, R.P. Feynman attempted to find a mathematical representation to express quantum dynamics of the general form for a double-slit experiment. His intuition on several slits with several walls in terms of Lagrangian instead of Hamiltonian resulted in a magnificent work. It was known as Feynman Path Integrals in quantum physics, and a large part of the scientific community still considers them a heuristic tool that lacks a sound mathematical definition. This paper aims to refute this prejudice, by providing an extensive and self-contained description of the mathematical theory of Feynman Path Integration, from the earlier attempts to the latest developments, as well as its applications to quantum mechanics. About a hundred years after the beginning of modern physics, it was realized that light could in fact show behavioral characteristics of both waves and particles. In 1927, Davisson and Germer demonstrated that electrons show the same dual behavior, which was later extended to atoms and molecules. We shall follow the method of integration with some modifications to construct a generalized Lebesgue-Bochner-Stieltjes (LBS) integral of the form , where u is a bilinear operator acting in the product of Banach spaces, f is a Bochner summable function, and μ is a vector-valued measure. We will demonstrate that the Feynman Path Integral is consistent and can be justified mathematically with LBS integration approach.

Script-Based GPU-Ready ELM Development for Continuous Code Integration
2024年
Designing and optimizing complex scientific code for new computing architectures is a challenging task. To address this issue in the E3SM land model (ELM) development, we developed a software tool called SPEL, which facilitates code generation, verification, and performance tuning using compiler directives within a Function Unit Test framework. In this paper, we present a SPEL extension that leverages the version control system (e.g., Git) to autonomous code generation and demonstrate its application to continuous code integration and development of the ELM software system. The study can benefit the scientific software development community.

情景感统训练在感觉统合失调患儿中的应用效果
2024年
目的探讨情景感统训练在感觉统合失调患儿中的应用效果。方法选取2021年4月至2022年6月临沂市妇幼保健院接诊的48例感觉统合失调患儿,按照随机数字表法分为对照组和观察组,每组各24例。对照组采用传统感统训练,观察组采用情景感统训练,比较两组感觉统合评分。结果观察组前庭觉因子、触觉因子、本体觉因子、学习能力因子评分均高于对照组,差异有统计学意义(P<0.05)。结论情景感统训练在感觉统合失调患儿中的应用效果确切,值得应用推广。

Enable Excel-Based Basic Cybersecurity Features for End Users by Using Python-Excel Integration
2024年
In the digital age, the global character of the Internet has significantly improved our daily lives by providing access to large amounts of knowledge and allowing for seamless connections. However, this enormously interconnected world is not without its risks. Malicious URLs are a powerful menace, masquerading as legitimate links while holding the intent to hack computer systems or steal sensitive personal information. As the sophistication and frequency of cyberattacks increase, identifying bad URLs has emerged as a critical aspect of cybersecurity. This study presents a new approach that enables the average end-user to check URL safety using Microsoft Excel. Using the powerful VirusTotal API for URL inspections, this study creates an Excel add-in that integrates Python and Excel to deliver a seamless, user-friendly interface. Furthermore, the study improves Excel’s capabilities by allowing users to encrypt and decrypt text communications directly in the spreadsheet. Users may easily encrypt their conversations by simply typing a key and the required text into predefined cells, enhancing their personal cybersecurity with a layer of cryptographic secrecy. This strategy democratizes access to advanced cybersecurity solutions, making attentive digital integrity a feature rather than a daunting burden.

Promoting the Real Economy by the Integration of Digital Technology and the Real Economy:On the Influence to Biased Technical Change
2024年
The deep integration of digital technology and the real economy is a vital engine for boosting high-quality growth of the real economy.As a result,it is necessary to investigate the effects of this integration on the real economy.This paper develops a two-sector model that incorporates the production sector and the technology research and development sector,taking into account both the factor attribute and the technical attribute of digital technology.Digital capital,general capital,skilled labor,and unskilled labor are considered as intermediate inputs in the model.Furthermore,this paper examines the effects of two integration modes,i.e.,factor-based integration and technology-based integration,on the development of the real economy and the biased technical change from a theoretical perspective.Empirical tests are conducted to support the analysis.The findings indicate that both factor-based integration and technology-based integration contribute positively to the development of the real economy,although technology-based integration exhibits diminishing marginal effects.Heterogeneity analysis reveals that factor-based integration plays a more significant role in promoting the development of the real economy in regions with geographical advantages,low levels of human resources,high marketization levels,or low market segmentation.On the other hand,technology-based integration assumes a greater role in facilitating the development of the real economy in regions with geographical disadvantages,low costs on human resources,low marketization levels,or high market segmentation.Further analysis demonstrates that the integration of digital technology and the real economy leads to digital capital-biased technical change and skilled labor-biased technical change.Therefore,it is imperative for the public sector to encourage the expansion of both factor-based integration and technology-based integration in the real economy.Additionally,it is also important to develop a reasonable industry layout plan and enhance the skill le

新时代城乡融合发展:“三生融合”演进及其驱动因素
2024年
生产融合—生活融合—生态融合(简称“三生融合”)是新时代大力推进城乡深度融合和实现城乡共同富裕的必由之路。运用改进CRITIC法、改进耦合协调度模型、剪刀差模型、莫兰指数和地理探测器模型,深入探究2012—2021年我国城乡“三生融合”的演进特征及驱动因素。结果表明:(1)城乡“三生融合”总体水平和子系统水平均出现不同程度上升,但生态融合与生产融合、生活融合演化速率剪刀差不断拉大,三者极差呈现“V”型变化;(2)生态融合是制约“三生融合”系统耦合的主要因素;(3)城乡“三生融合”耦合协调度在观察期内上升速率放缓,整体陷入发展困境,而且区域异质性明显,高值区域由东中部地区向西部地区和东北地区扩展;(4)政府干预程度等显著影响城乡“三生融合”耦合协调度,各个因素对子系统存在不同的影响;(5)子系统水平和耦合协调度水平问题区域分析表明,我国城乡融合发展主要问题区域集中在西部地区和东北地区。

“一统三融”背景下高职院校科教融汇与产教融合耦合发展机制构建
2024年
建立高职院校科教融汇与产教融合耦合发展机制是“一统三融”背景下贯彻落实教育、科技、人才强国战略的重要组成部分,是推进产科教一体化发展的基石,有利于形成产业、科技、教育多方主体利益互嵌、资源统整的共生系统,有助于高技能人才创新能力培养,驱动高职院校赋能新质生产力形成。高职院校科教融汇与产教融合的双向赋能与互促关系构成了二者耦合发展的内在机理,耦合发展的实现依赖于包括目标机制、动力机制、协调机制与保障机制四个维度的体系构建。高职院校实施有组织的科研范式、建立科学的评价标准体系、推进产科教融合共同体实体化建设、加强地方政府的统筹治理是耦合机制实现的有效路径。
