Embankment base strengthening and construction of working platforms on soft soil

Geosynthetics have been used for decades in infrastructure construction, especially in traffic construction and geotechnics. Despite this, there is still a relatively low uptake of methods for designing solutions using these materials. While the applications of geogrids (or more broadly: geosynthetics) in reinforced soil structures (retaining walls, steep slopes) and the associated design methods are well described in the literature and standards, there is much more modest knowledge available on applications related to the reinforcement of the subsoil directly under road and railway pavement structures, the construction of working platforms on soils with very low bearing capacity, or increasing the fatigue life of the pavement itself. This situation is due, among other things, to the fact that different geosynthetics, including different geogrids, affect the bearing capacity of the subsoil and the durability of the structure in different and often very different ways. Hence – unlike, for example, in the case of retaining walls – it is difficult to develop a one-size-fits-all design method covering this range of applications. It is necessary to rely on the experience of manufacturers of particular varieties of geogrids or geo-grids and to use design methods developed by them based on this experience. This article presents the technology of geocellular mattresses used primarily in the base of embankments on weak and deformable grounds, as well as for the construction of temporary working platforms. The performance of structures in complex and complicated geotechnical conditions is analysed on the example of completed projects. The results of back analysis of structures subjected to real-scale tests are presented, which can be used for preliminary analysis of solutions in numerical modelling programmes

Путь к инновационному дизайну педагогического образования: Профессиональная идентичность учителей как центральное понятие

Teacher education program as a focal platform of teacher identity construction has extensively been explored recently. This study examines the Engage, Study, Activate (ESA) teacher education model's effectiveness in fostering teacher professional identity. Utilizing Freeman’s (2020) evaluation model, the ESA model's content and design were analyzed. A qualitative case study followed one participant over a year, using written narratives, interviews, and demos. Applying document and thematic analysis, findings showed 93% alignment with Freeman’s knowledge base and identified three key themes: forming personal beliefs, overcoming self-doubt, and developing global citizenship. The study underscores the importance of incorporating intercultural topics, AI, and digital tools into the ESA program, highlighting its value for pre-service teachers, educators, curriculum developers, and researchers in understanding teacher identity.

Democracy and the ‘citizen-soldier’ military: The case of Kosovo and Israel

The intention of Kosovo’s government to establish a ‘citizen-soldier’ military creates an opportunity to do the ‘right thing from the beginning’—the current comparative study elaborates on the steps that have to be taken in order to establish a military in a young and small democratic state, with a strong normative base, that will provide confidence in the defence system alongside constructive socialisation. The structure of constitutional analysis serves as a base for in-depth discussion concerning the military service model in democratic states. The analysis is followed by an elaboration on the ‘citizen-soldier’ military model in the context of cultural aspects and the connection to the constitutional base, combined with an analysis of Israel’s and Kosovo’s social–cultural features, security challenges, and geo-strategic situations, similarities and opportunities regarding implementation of a military model. The study reveals that in democratic states, the ‘citizen-soldier’ model has to be anchored in the culture and in the constitution in order to prevent social conflicts concerning rights and duties, establishing a constructive social platform that empowers national resilience alongside defensive abilities. Kosovo’s success in implementing a ‘citizen-soldier’ model is built on the adoption of positive ways of social integration using Israel’s experience while minimising its weaknesses: the existence of constitutional definitions that will balance civilians’ rights and duties in the context of military duty, harnessing the education system as a socialisation agent, and establishment of a reserve military force that will be anchored in national duty, in the security view and the social view.

Design and implementation of a cloud computing based vocational college course teaching practice platform

In recent years, China’s vocational college education informatization construction has achieved significant results, but there is still a certain gap with the requirements of university informatization construction and education development. Firstly, the foundation for the construction of a public service platform for professional course resources is relatively weak, and there are insufficient shared mathematical professional course resources; Secondly, the construction of information infrastructure in some vocational college lags behind, and there is a shortage of high-quality and shared course resources. In addition, the application rate of information technology in professional course resources in vocational colleges is relatively low, which cannot fully meet the actual needs of China's vocational college reform and development. This article applies the theoretical foundation and practical methods of cloud computing to research and design a cloud computing based vocational college course teaching resource platform.

Unlocking Oxetane Potential: Modular Synthetic Platform for the Concise Synthesis of Acyclic Oligo-Isoprenoids and Terpenoids.

Terpenes occupy a unique place among the secondary metabolites due to their broad utility and extraordinary structural diversity. Their synthesis via polyene cyclization, either biomimetic or enzymatic, represents the cutting edge of modern synthetic chemistry. However, these endeavors have been inherently tied to the availability of natural and non-natural acyclic polyene starting materials. Herein, we report an oxetane-based platform for the modular construction of oxygenated polyolefins with precise geometric control. This "tail-to head" iterative method leverages the site-selective cross-metathesis of terminal olefins to form an alkylidene oxetane moiety and the regioselective ring opening of alkenyl-oxetanes for chain elongation. In addition, the unique and peculiar propensity of alkylidene oxetane fragment in various reactions was also revealed and exploited for site-selective functionalization, cyclization, and as a protecting group in polyenes.

Nickel-Catalyzed Enantioselective Alkylation of Primary Phosphines.

Functional molecules derived from stereogenic phosphorus centers have important applications in the discovery of drugs and agrochemicals. They are also widely utilized as chiral ligands or organocatalysts for diverse asymmetric transformations. However, access to P-stereogenic motifs has always been regarded as a highly challenging yet desirable goal in organic synthesis. The development of general and practical methods for the stereoselective construction of synthetically versatile P(III)-stereogenic phosphines is particularly appealing but remains elusive. Herein, we describe a nickel-catalyzed asymmetric alkylation of primary phosphines with alkyl halides for the synthesis of P-stereogenic secondary phosphine-boranes with high enantioselectivity and broad substrate scope. The resulting optically active secondary phosphine-boranes allow for further stereospecific transformations, thereby establishing a modular and efficient platform for the diversity-oriented construction of P-stereogenic phosphine compounds.

Research on the Construction of Vocational School-Enterprise Cooperation Service Platform Based on Micro-services

With the deep integration of school-enterprise cooperation in higher vocational colleges, it is necessary to use micro-service technology for targeted analysis of various behavioral data involved in school-enterprise cooperation, and extract valuable information as the basis for guide school-enterprise cooperation work, to shift school-enterprise cooperation work from “business-driven” to more precise “data-driven” [1]. This article uses big data analysis as a means, adopts micro-service technology, and takes school-enterprise cooperation and industry education integration as the concept. Through the needs analysis of the college, the overall architecture of the school-enterprise cooperation service platform is designed. From business processes, big data analysis and intelligent visualization, the deep integration of school-enterprise joint training of teachers, school-enterprise collaborative teaching, and school-enterprise joint promotion of employment are achieved, and the expected effect is worth promoting.

Research on the digital inheritance and development of Weixian paper-cutting from the perspective of intangible cultural heritage

As a traditional folk art in northern China, Weixian paper-cutting has been listed in the national intangible cultural heritage list and has rich cultural connotations and artistic value. However, with the acceleration of modernization and changes in lifestyle, the inheritance of Weixian paper-cutting faces severe challenges, including a decrease in the number of inheritors, shrinking market demand, and a decline in the younger generation's attention to traditional culture. The rapid development of digital technology has provided a new opportunity for the inheritance and development of Weixian paper-cutting. This study aims to explore the application and practice of digital technology in the inheritance of Weixian paper-cutting from the perspective of intangible cultural heritage protection. The study found that digital technology can not only enhance the cultural communication power of Weixian paper-cutting, but also bring it the possibility of innovative design and broaden its marketization path. Through the analysis of the digital practice of Weixian paper-cutting, this paper puts forward countermeasures and suggestions in the future in terms of digital platform construction, policy support and inheritor training, providing a theoretical basis and practical reference for the sustainable inheritance of Weixian paper-cutting.

Innovating Civil Engineering: Strategies for Fostering Stakeholder Engagement in the Circular Economy

Sustainability and circular economy principles are increasingly important in civil engineering, as highlighted by the United Nations Environmental Programme in 2023 the construction activities represented 36% of global energy use in 2020. However, the sector's focus on reducing operational carbon overshadows the need for addressing embodied carbon from materials like cement, steel, and aluminium. To address this, a shift towards incentivizing all supply chain stakeholders and cultivating collaborative models is necessary. This research provides an initial scoping for the development of the Lithuanian Construction Materials Reuse Optimization (LSEPO) platform, a pioneering regional initiative fostering a marketplace for reused building materials. Such platforms are recognized for their potential to overcome sustainability barriers by utilizing digital technologies for efficient data management and stakeholder collaboration. Our research identifies a significant gap in the existing literature concerning effective stakeholder engagement strategies critical for the success of such platforms. To bridge this gap, we employed a three-tiered methodological approach: firstly, a semi-structured literature analysis delved into existing stakeholder engagement strategies within the circular economy. This review highlighted a fragmented understanding of incentives and collaboration dynamics across different sectors. Secondly, a content analysis of global material exchange and circular construction platforms provided insights into best practices, showcasing successful communication methods, innovative incentive models, and robust collaboration frameworks. Lastly, integrating these findings, our study proposes a conceptual stakeholder engagement framework tailored for social innovation in civil engineering, more specifically Lithuanian Construction Materials Reuse Optimization (LSEPO). Practical implications of our findings underscore the necessity for platforms like LSEPO to incorporate adaptive engagement strategies that are context-sensitive and inclusive, facilitating a broad spectrum of stakeholder inputs. The study demonstrates that effective stakeholder engagement goes beyond traditional communication methods; it requires a systemic integration of technological innovation and incentive alignment to promote sustained participation and collaboration. By providing a comprehensive foundation for the development of the LSEPO platform, this research not only aims to advance it as a beacon of social innovation and environmental stewardship within the civil engineering sector but also sets a benchmark for future initiatives aiming to embed circular economy principles effectively.

Does Government Digital Transformation Drive High-Quality Urban Economic Development? Evidence from E-Government Platform Construction

Digitalization represents a pivotal global development trend and serves as a significant force propelling economic and social transformation. This manuscript uses the global Malmquist–Luenberger (GML) model to estimate green total factor productivity (GTFP) across 284 Chinese cities from 2003 to 2018, taking the pilot policy of “construction and application of e-government public platforms based on cloud computing” as an example to assess the impact of government digital transformation on the qualitative development of the economy by using a difference-in-differences model to explore the path of its role and driving mechanism. The results reveal that government digital transformation promotes the qualitative improvement of the city’s economic development, and its driving effect shows a marginal incremental law. Moreover, government digital transformation can contribute to the formation of a “latecomer advantage” in the lagging regions, which creates a “catch-up effect” on the regions with favorable development foundations, excellent geographical conditions, high urban ranking, and high education quality. Additionally, government digital transformation boosts economic and social development quality through both innovation spillover and structural optimization.

Experimental study of a high-power generation platform for ocean thermal energy conversion

Ocean Thermal Energy Conversion (OTEC) is a form of power generation that utilizes the temperature difference between the upper and lower layers of the ocean. This paper presents the design and construction of a land-based experimental platform for OTEC using R134a as the working fluid. Through experimental research, we investigated the performance of the thermal energy cycle system under varying external environmental conditions, such as temperature and flow rate. The results show that the net output power of the system increases with the temperature and flow rate of the warm seawater. Similarly, an increase in the cold seawater temperature and flow rate leads to an increase in net output, though the increase is less significant at higher power levels when compared to changes in warm seawater conditions. Adjusting the evaporation pressure to increase the turbine inlet and outlet pressure difference initially increases the output power but then remains constant. The highest recorded output power during testing was 48kW, with the turbine achieving an isentropic efficiency of 80%, and the maximum system efficiency reached 2%. This study provides theoretical basis and empirical data for system design, which can promote the application in the field of OTEC and contribute to the development of renewable energy.

Bio‐inspired 3D Sub‐Microstructures Coupling of Au Nanoparticles for SERS Detection of Trace Fentanyl

Abstract3D surface‐enhanced Raman scattering (SERS) platforms with multi‐dimensional hotspots and better tolerance to laser misfocus show great potential for the rapid detection of trace fentanyl. However, the complex fabrication process of 3D fine structures limits the wide‐ranging application of the SERS technique. Herein, a 3D SERS‐active platform is fabricated utilizing a scalable and cost‐effective strategy that involves the electroless deposition of dense Au nanoparticles on natural butterfly wing scales (b‐wings@Au). The resultant b‐wings@Au proves to be sensitive and reliable, with a lower limit of detection of 4× 10−12 m and an enhancement factor (EFexp) of 1.74 × 108 for fentanyl. Furthermore, it exhibits excellent reproducibility, as evidenced by a relative standard deviation of less than 5%, and also demonstrates outstanding stability. The obtained high EFexp is due to the combined effects of the electromagnetic mechanism, involving the enhanced electromagnetic field generated by 3D periodic hotspots, and the chemical mechanism, involving the charge transfer from fentanyl to Au surface. Additionally, the as‐prepared 3D substrate realizes the trace detection of nine fentanyl analogs. This study provides new ideas for the controllable construction of sensitive SERS platforms for drug detection, ultimately advancing the fields of 3D substrates in booming SERS‐based technologies.

Construction of CXCR4 Receptor-Targeted CuFeSe2 Nano Theranostic Platform and Its Application in MR/CT Dual Model Imaging and Photothermal Therapy.

Targeting, imaging, and treating tumors represent major clinical challenges. Developing effective theranostic agents to address these issues is an urgent need. We introduce an "all-in-one" tumor-targeted theranostic platform using CuFeSe2-based composite nanoparticles (CuFeSe2@PA) for magnetic resonance (MR) and computed tomography (CT) dual model imaging-guided hyperthermia tumor ablation. Plerixafor (AMD3100) is bonded to the surface of CuFeSe2 as a targeting unit. Due to the robust interaction between AMD3100 and the overexpressed Chemokine CXC type receptor 4 (CXCR4) on the membrane of 4T1 cancer cells, CuFeSe2@PA specifically recognizes 4T1 cancer cells, enriching the tumor region. CuFeSe2@PA serves as a contrast agent for T2-weighted MR imaging (relaxivity value of 1.61 mM-1 s-1) and CT imaging. Moreover, it effectively suppresses tumor growth through photothermal therapy (PTT) owing to its high photothermal conversion capability and stability, with minimized side effects demonstrated both in vitro and in vivo. CuFeSe2@PA nanoparticles show potential as dual-mode imaging contrast agents for MR and CT and provide an effective means of tumor treatment through photothermal therapy. The surface modification with Plerixafor enhances the targeting ability of the nanoparticles, performing more significant efficacy and biocompatibility in the 4T1 cancer cell model. The study demonstrates that CuFeSe2@PA is a promising multifunctional theranostic platform with clinical application potential.

Digital twin method for intelligent lifting of cable structures under multi-collaborative mode

In order to ensure the high efficiency and quality consistency of cable structure in each construction stage, this study proposes a digital twin method for intelligent lifting of cable structure under multi-collaborative mode. Firstly, a construction and operation methods of the digital twin logic model are formed. In the logical model, a relationship between the transmission and iteration of construction information in the collaborative process is defined. In order to realize the adaptability of working conditions, the coupling relationship between construction step and structural elevation is established. A cable structure lifting analysis model driven by an improved long short-term memory neural network is proposed, which effectively solves the problem of poor convergence of the traditional finite element method. An automatic time window selection method is formed for the neural network. An adaptive moment estimation method is used for neural network parameter optimization, which improves the efficiency and accuracy of the analysis. Taking the lifting process of a cable truss structure test model as an example, a digital twin collaborative construction platform is established to verify the effectiveness and feasibility of the research method. The results show that the digital twin logic model realizes the process collaboration, scene collaboration and data collaboration, and significantly improves the stability of construction quality and the linkage of construction process. Through the improved long short-term memory neural network, the coupling relationship between the construction step and the structural elevation is established, which accurately guides the whole construction process.

Ingenious dual-circle DNA walker-mediated electrochemical biosensor for rapid and ultrasensitive detection of microRNA

In this work, an ingenious dual-circle DNA walker (DCDW) with pretty fast walking speed and high amplification efficiency was developed for rapid and ultrasensitive electrochemical detection of microRNA-221 (miRNA-221) related to liver cancer, combined with the toehold-mediated strand-displacement reactions (TSDRs). Impressively, compared with the traditional DNA walker, the DCDW with unique double-stranded interlocked DNA nanostructure not only possesses higher stability, flexibility, and anti-entanglement ability, but also enables more functional domain in a smaller area, thereby enhancing the local concentration, which can greatly improve the working efficiency. As a validation, the electrochemical biosensor realized rapid and ultrasensitive detection of miRNA-221 with a reaction time of 15 min and detection limit down to 1.9 aM, and had been applied in MHCC97L and HeLa cancer cell lysates, thus providing an innovative insight to design intelligent functional interlocked DNA walkers for ultimate application in the construction of biosensing platform and miRNA detection in biological sample.

The catalytic three‐component radical carboamination of alkenes has recently emerged as an alternative and robust platform for the rapid construction of diverse and valuable amines. Despite great advances in this field, new methods that enable highly selective access to new chemical space surrounding the amine functional groups are still in high demand. Herein, we report a generally applicable visible light‐induced copper‐catalyzed three‐component radical cyanoalkylamination reaction of alkenes, oxime carbonates, and benzoyloxycarbamates. This protocol demonstrates high chemo‐selectivity, broad substrate scope, and good functional group tolerance, providing access to a variety of cyanoalkylated aliphatic amines with good yields.

Research on Dual-Phase Composite Forming Process and Platform Construction of Radial Gradient Long Bone Scaffold.

The structure and composition of natural bone show gradient changes. Most bone scaffolds prepared by bone tissue engineering with single materials and structures present difficulties in meeting the needs of bone defect repair. Based on the structure and composition of natural long bones, this study proposed a new bone scaffold preparation technology, the dual-phase composite forming process. Based on the composite use of multiple biomaterials, a bionic natural long bone structure bone scaffold model with bone scaffold pore structure gradient and material concentration gradient changes along the radial direction was designed. Different from the traditional method of using multiple nozzles to achieve material concentration gradient in the scaffold, the dual-phase composite forming process in this study achieved continuous 3D printing preparation of bone scaffolds with gradual material concentration gradient by controlling the speed of extruding materials from two feed barrels into a closed mixing chamber with one nozzle. Through morphological characterization and mechanical property analysis, the results showed that BS-G (radial gradient long bone scaffolds prepared by the dual-phase composite forming process) had obvious pore structure gradient changes and material concentration gradient changes, while BS-T (radial gradient long bone scaffolds prepared by printing three concentrations of material in separate regions) had a discontinuous gradient with obvious boundaries between the parts. The compressive strength of BS-G was 1.00 ± 0.19 MPa, which was higher than the compressive strength of BS-T, and the compressive strength of BS-G also met the needs of bone defect repair. The results of in vitro cell culture tests showed that BS-G had no cytotoxicity. In a Sprague-Dawley rat experimental model, blood tests and key organ sections showed no significant difference between the experimental group and the control group. The prepared BS-G was verified to have good biocompatibility and lays a foundation for the subsequent study of the bone repair effect of radial gradient long bone scaffolds in large animals.
