Design and Implementation of USB Key System Based on Dual-Factor Identity Authentication Protocol

With the increasing demand for information security, traditional single-factor authentication technology can no longer meet security requirements. To this end, this paper proposes a Universal Serial Bus (USB) Key hardware and software system based on a two-factor authentication protocol, aiming to improve the security and reliability of authentication. This paper first analyzes the current status and technical principles of USB Key-related research domestically and internationally and designs a two-factor authentication protocol that combines impact/response authentication and static password authentication. The system consists of a host computer and a USB Key device. The host computer interacts with the USB Key through a graphical user interface. The Secure Hash Algorithm 1 (SHA-1) and MySQL database are used to implement the authentication function. Experimental results show that the designed two-factor authentication protocol can effectively prevent replay attacks and information tampering, and improve the security of authentication. If the corresponding USB Key is not inserted, the system will prompt that the device is not found. Once the USB Key is inserted, user identity is confirmed through two-factor verification, which includes impact/response authentication and static password authentication.

Surface Modification of Composite Coating for Marine Application: A Short Review

Corrosion is one of the phenomena that affects the deterioration of materials in offshore applications. Marine corrosion is particularly aggressive, due to the high salt content and low electrical resistivity of seawater. Corrosion cannot be stopped completely, but the reaction can be slowed down. Applying coating is an effective and widely used method to protect metal surfaces from corrosion. Coatings act as a barrier between the metal and its environment, preventing or slowing down the corrosive processes. Pursuant to ISO 12944, the most commonly used generics for coating systems in marine service are alkyd, acrylic, ethyl silicate, epoxy, vinyl ester, polyurethane, polyaspartic, and polysiloxane. The latest innovations in marine coatings still use a layer-by-layer coating method (e.g. primer coats, intermediate coats, and top coats) depending on thickness. Marine structures exposed to the atmospheric zones are usually coated with one or two coats of epoxy. A slightly more costly system of one coat of zinc-rich primer, one coat of epoxy, and one coat of aliphatic polyurethane may provide better performance. Coating systems for the atmospheric zones are frequently used in the intertidal and splash zones. Immersion zones of marine structures are commonly coated with one or two coats of 100% solid epoxy or three coats of solvent-borne epoxy. A single polymer as a generic coating have limitations. Adding fillers is a common method to improve the properties of polymers to become a composite. In marine coatings, fillers are still limited to glass flakes and powder. Poor dispersion and agglomeration might reduce the effectiveness of fillers in the matrix, which decreases the adhesion properties. The fillers must be surface modification before the application. This review provides a comprehensive and critical review of the current research status of composite coatings that serve as candidates to be used in marine coating.

Current Research Status, Opportunities, and Future Challenges of Nine Representative Persistent Herbicides.

Pesticides are extensively utilized in contemporary agriculture to manage pests, enhance crop yields, and sustain productivity. Nevertheless, the persistent herbicide represents a dual-edged weapon. On one hand, their prolonged efficacy enables reduced application frequency during crop growth seasons, resulting in cost savings on labor. However, the presence of these residues within fields poses safety risks to soil quality, sensitive crops in subsequent rotations, agricultural product quality, and the ecological environment. This review presents a comprehensive review on the mechanisms of action, application risks, ecotoxicology, and residue analysis methods of nine representative persistent herbicides (namely, atrazine, imazethapyr, imazapic, mesosulfuron-methyl, halosulfuron-methyl, fomesafen, diflufenican, quinclorac, and pyroxasulfone). The objective is to guide their scientific and rational utilization in agricultural practices while minimizing phytotoxicity risks and effectively monitoring and controlling soil pollution. These can not only provide practical recommendations for mitigating potential plant toxicity and ecological environmental risks but also contribute valuable technical insights for efficient soil pollution monitoring and prevention. Additionally, unaddressed research objectives were also anticipated.

What do we know about police leadership? A review of the current status of police leadership research and practice, with suggestions for future research directions

ABSTRACT This article, which consists of three systematic reviews covering the period 1992–2023, focuses on why scholarly knowledge of effective police leadership is limited. The literature on police leadership amounts to just 197 peer-reviewed journal articles; most of these are leader-centric and tend to uncritically echo the conventional literature, focusing on police leaders` traits and styles as independent of context and practice. Using three surveys of peer-reviewed journal articles and a sample of around ten contributions to the contemporary critical leadership literature on police leadership research, we make a series of recommendations for future directions. Firstly, the collective and relational nature of police leadership, which is understood to be a co-production involving leaders and followers, is under-researched. Secondly, studies are needed to narrow the gap between leadership theories and police leadership practice and recognise the need for research on what works or does not work. Thirdly, conceptual parameters and their effects on police leadership, particularly organisational, structural, and hierarchical conditions, should be examined in more detail. Each suggestion highlights the socially constructed, situated, relational processes and practice-orientated nature of leadership, which is essential if future research is to be relevant to police forces.

Recent Advances in Propylene-Based Elastomers Polymerized by Homogeneous Catalysts.

Propylene-based elastomers (PBEs) have received widespread attention and research in recent years due to their structural diversity and excellent properties, and are also an important area for leading chemical companies to compete for layout, but efficient synthesis of PBEs remains challenging. In this paper, we review the development of PBEs and categorize them into three types, grounded in their unique chain structures, including homopolymer propylene-based elastomers (hPBEs), random copolymer propylene-based elastomers (rPBEs), and block copolymer propylene-based elastomers (bPBEs). The successful synthesis of these diverse PBEs is largely credited to the relentless innovative advancements in homogeneous catalysts (metallocene catalysts, constrained geometry catalysts, and non-metallocene catalysts). Consequently, we summarize the catalytic performance of various homogeneous catalysts employed in PBE synthesis and delve into their effect on molecular weight, molecular weight distribution, and chain structures of the resulting PBEs. In the end, based on the current academic research and industrialization status of PBEs, an outlook on potential future research directions for PBEs is provided.

EXAMINING CLINICAL STUDIES ABOUT CUPPING THERAPY IN TURKEY: A SYSTEMATIC REVIEW AND BIBLIOMETRIC ANALYSIS

There is insufficient quantitative data available on the characteristics of research conducted on cupping therapy. This insufficiency complicates our ability to achieve a more profound understanding of the subject. The primary aim of this work was to assess the outcome of clinical studies outputs in cupping therapy and discuss methodological gaps. Six databases PubMed, Cochrane Library, Medline, TUBITAK ULAKBIM DergiPark, Science Direct, and Google Scholar, were systematically searched from their inception to January 2024. Performance analysis was made in the study. Frequency and distributions were analyzed with SPSS 24. The software Wordclouds software was used to generate visualization. Within the scope of the research, 26 studies that met the selection criteria were accessed. It was determined that the majority of the studies (46.16%) were written in 2019-2021. The most used technique was 3 S (73.07%), and the most preferred point was du 14 point. While the top two variables are oxidative stress and heavy metal levels, the co-word analysis of keywords showed that "wet cupping therapy" was the largest single node. The findings from this bibliometric study provide the current status and productivity in clinical research of cupping therapy over the past ten years. It is seen that despite the challenges facing the field of cupping research, which include standardization, legal, and reporting quality, there has been an increase in publications to mitigate disease-related symptoms in clinical populations.

Action research in LSCM since 2010 – the emergence of design science

PurposeThe purpose of this study is the review of current status of action research (AR) and design science (DS) in logistics and supply chain management (SCM) and to compare AR and DS.Design/methodology/approachThe paper’s approach comprises the literature review of AR and DS articles.FindingsFirst, not much has changed in terms of number of published AR articles, despite frequent calls for more relevant research. One explanation is the academic system. Second, there is an increased focus on theory, which from a positive perspective is a sign of our field maturing, yet the academic system and current editorial philosophies may also contribute to this development. Third, DS is emerging as a potential replacement of AR.Research limitations/implicationsThe study provides suggestion for both authors and editors when it comes to the increased focus on theory. Comparing AR and DS, the two approaches are similar. However, while the increased focus on theory is reflected in DS, it also seems to be an inferior approach for ill-defined change-focused problems, requiring in-depth, collaborative, data-rich, longitudinal studies.Originality/valueThis paper is the first article that reviews and compares AR and DS in LSCM.

Bioinformatics in Russia: history and present-day landscape.

Bioinformatics has become an interdisciplinary subject due to its universal role in molecular biology research. The current status of Russia's bioinformatics research in Russia is not known. Here, we review the history of bioinformatics in Russia, present the current landscape, and highlight future directions and challenges. Bioinformatics research in Russia is driven by four major industries: information technology, pharmaceuticals, biotechnology, and agriculture. Over the past three decades, despite a delayed start, the field has gained momentum, especially in protein and nucleic acid research. Dedicated and shared centers for genomics, proteomics, and bioinformatics are active in different regions of Russia. Present-day bioinformatics in Russia is characterized by research issues related to genetics, metagenomics, OMICs, medical informatics, computational biology, environmental informatics, and structural bioinformatics. Notable developments are in the fields of software (tools, algorithms, and pipelines), use of high computation power (e.g. by the Siberian Supercomputer Center), and large-scale sequencing projects (the sequencing of 100 000 human genomes). Government funding is increasing, policies are being changed, and a National Genomic Information Database is being established. An increased focus on eukaryotic genome sequencing, the development of a common place for developers and researchers to share tools and data, and the use of biological modeling, machine learning, and biostatistics are key areas for future focus. Universities and research institutes have started to implement bioinformatics modules. A critical mass of bioinformaticians is essential to catch up with the global pace in the discipline.

The DSW to the Rescue? A Response to Feldman

Feldman's appraisal of the current status of social work research, using as its touchstone the 1991 Austin Report, is a frank and fair appraisal of how the discipline has come short of fulfilling its aspirations to become a more science-based profession. In many ways, Feldman has stood in the center of research developments within our field for the past 40 years or longer. He offers informed and thoughtful analyses of what we have accomplished and what is left undone. He asserts that part of the problem is the sluggish growth in the number of research doctorates being produced in our field. Obviously, without the production of highly trained social work researchers, the scholarly and science-based contributions to our field are limited. In this response, I contend that the burgeoning growth of the number of practice doctoral graduates, Doctor of Social Works (DSWs), may provide significant resources to augment the science of social work. In reality, the older generation of DSW graduates made highly important contributions to the science of social work, and the new generation stands poised to replicate this phenomenon.

Technology Progress in High-Frequency Electromagnetic In Situ Thermal Recovery of Heavy Oil and Its Prospects in Low-Carbon Situations

Heavy oil resources are abundant globally, holding immense development potential. However, conventional thermal recovery methods such as steam injection are plagued by high heat loss, substantial carbon emissions, and significant water consumption, making them incompatible with carbon reduction goals and the sustainable socioeconomic development demands. A new method of high-frequency electromagnetic in situ heating, which targets polar molecules, can convert electromagnetic energy into heat so as to achieve rapid volumetric heating of the reservoir. This method has the potential to overcome the drawbacks of traditional techniques. Nevertheless, it faces significant drawbacks such as limited heating range and inadequate energy supply during later production stages, which necessitates auxiliary enhancement measures. Various enhancement measures have been reported, including nitrogen injection, hydrocarbon solvent injection, or the use of nano-metal oxide injections. These methods are hindered by issues such as pure nitrogen being easy to breakthrough, high costs, and metal pollution. Through extensive literature review, this article charts the evolution of high-frequency electromagnetic in situ heating technology for heavy oil and the current understanding of the coupled heat and mass transfer mechanisms underlying this technology. Moreover, based on a profound analysis of the technology’s progression trends, this work introduces a new direction: CO2-N2 co-injection as an enhancement strategy for high-frequency electromagnetic in situ heavy oil recovery. There is promising potential for the development of new technologies in the future that combine high efficiency, low carbon emissions, environmental friendliness, economic viability, and energy conservation. Furthermore, some research prospects in low-carbon situations and challenges for the new technology in future are presented in detail. All in all, the contribution of the paper lies in the summarizing of some main drawbacks of current enhanced electromagnetic in situ thermal recovery methods, and presents a novel research direction of using CO2-N2 co-injection as an enhancement strategy based on its current research status in low-carbon situations.

Statins in Mitigating Anticancer Treatment-Related Cardiovascular Disease.

Certain anticancer therapies inevitably increase the risk of cardiovascular events, now the second leading cause of death among cancer patients. This underscores the critical need for developing effective drugs or regimens for cardiovascular protection. Statins possess properties such as antioxidative stress, anti-inflammatory effects, antifibrotic activity, endothelial protection, and immune modulation. These pathological processes are central to the cardiotoxicity associated with anticancer treatment. There is prospective clinical evidence confirming the protective role of statins in chemotherapy-induced cardiotoxicity. Numerous preclinical studies have demonstrated that statins can ameliorate heart and endothelial damage caused by radiotherapy, although clinical studies are scarce. In the animal models of trastuzumab-induced cardiomyopathy, statins provide protection through anti-inflammatory, antioxidant, and antifibrotic mechanisms. In animal and cell models, statins can mitigate inflammation, endothelial damage, and cardiac injury induced by immune checkpoint inhibitors. Chimeric antigen receptor (CAR)-T cell therapy-induced cardiotoxicity and immune effector cell-associated neurotoxicity syndrome are associated with uncontrolled inflammation and immune activation. Due to their anti-inflammatory and immunomodulatory effects, statins have been used to manage CAR-T cell therapy-induced immune effector cell-associated neurotoxicity syndrome in a clinical trial. However, direct evidence proving that statins can mitigate CAR-T cell therapy-induced cardiotoxicity is still lacking. This review summarizes the possible mechanisms of anticancer therapy-induced cardiotoxicity and the potential mechanisms by which statins may reduce related cardiac damage. We also discuss the current status of research on the protective effect of statins in anticancer treatment-related cardiovascular disease and provide directions for future research. Additionally, we propose further studies on using statins for the prevention of cardiovascular disease in anticancer treatment.
