Authors: Ghosh Rounak , Mani Christian , Krafczyk Roland , Schnell Rupert , Talma Auke , Blume Anke , Dierkes Wilma K.
Published: May 2024

Composites revolutionize material performance, fostering innovation and efficiency in diverse sectors. Elastomer-based polymeric composites are crucial for applications requiring superior mechanical strength and durability. Widely applied in automotives, aerospace, construction, and consumer goods, they excel under extreme conditions. Composites based on recycled rubber, fortified with reinforcing fillers, represent a sustainable material innovation by repurposing discarded rubber. The integration of reinforcing agents enhances the strength and resilience of this composite, and the recycled polymeric matrix offers an eco-friendly alternative to virgin elastomers, reducing their environmental impact. Devulcanized rubber, with inherently lower mechanical properties than virgin rubber, requires enhancement of its quality for reuse in a circular economy: considerable amounts of recycled tire rubber can only be applied in new tires if the property profile comes close to the one of the virgin rubber. To achieve this, model passenger car tire and whole tire rubber granulates were transformed into elastomeric composites through optimized devulcanization and blending with additional fillers like carbon black and silica–silane. These fillers were chosen as they are commonly used in tire compounding, but they lose their reactivity during their service life and the devulcanization process. Incorporation of 20% (w/w) additional filler enhanced the strength of the devulcanizate composites by up to 15%. Additionally, increased silane concentration significantly further improved the tensile strength, Payne effect, and dispersion by enhancing the polymer–filler interaction through improved silanization. Higher silane concentrations reduced elongation at break and increased crosslink density, as it leads to a stable filler–polymer network. The optimal concentration of a silica–silane filler system for a devulcanizate was found to be 20% silica with 3% silane, showing the best property profile.

Authors: Wang Cuizhen , Morris James T. , Smith Erik M.
Published: May 2024

Accompanying climate change and sea level rise, tidal marsh mortality in coastal wetlands has been globally observed that urges the documentation of high-resolution, 3D marsh inventory to assist resilience planning. Drone Lidar has proven useful in extracting the fine-scale bare earth terrain and canopy height. Beyond that, this study performed marsh biomass mapping from drone Lidar point cloud in a S. alterniflora-dominated estuary on the Southeast U.S. coast. Three point classes (ground, low-veg, and high-veg) were classified via point cloud deep learning. Considering only vegetation points in the vertical profile, a profile area-weighted height (HPA) was extracted at a grid size of 50 cm × 50 cm. Vegetation point densities were also extracted at each grid. Adopting the plant-level allometric equations of stem biomass from long-term S. alterniflora surveys, a Lidar biomass index (Lidar_BI) was built to represent the relative quantity of marsh biomass in a range of [0, 1] across the estuary. Compared with the clipped dry biomass samples, it achieved a comparable and slightly better performance (R2 = 0.5) than the commonly applied spectral index approaches (R2 = 0.4) in the same marsh field. This study indicates the feasibility of the drone Lidar point cloud for marsh biomass mapping. More advantageously, the drone Lidar approach yields information on plant community architecture, such as canopy height and plant density distributions, which are key factors in evaluating marsh habitat and its ecological services.

Authors: Wei Boxu , Yu Anxi , Tong Wenhao , He Zhihua
Published: May 2024

The video synthetic aperture radar (ViSAR) system can utilize high-frame-rate scene motion target shadow information to achieve real-time monitoring of ground mobile targets. Modeling the characteristics of moving target shadows and analyzing shadow detection performance are of great theoretical and practical value for the optimization design and performance evaluation of ViSAR systems. Firstly, based on the formation mechanism and characteristics of video SAR moving target shadows, two types of shadow models based on critical size and shadow clutter ratio models are established. Secondly, for the analysis of moving target shadow detection performance in ViSAR systems, parameters such as the maximum detectable speed of moving targets, the minimum clutter backscatter coefficient, and the number of effective shadow pixels of moving targets are derived. Furthermore, the shadow characteristics of five typical airborne/spaceborne ViSAR systems are analyzed and compared. Finally, a set of simulation experiments on moving target shadow detection for the Hamas rocket launcher validates the correctness and effectiveness of the proposed models and methods.
The Impact of Climate Change Transition Innovations on the Default Risk
Authors: Huang Yujun , Huang Zhihao
Published: May 2024

In the context of climate change mitigation and adaptation, climate risks stemming from climate transition innovations have garnered significant attention due to concerns about the inadequate climate finance. To shed light on the climate transition risk posed by innovations, this study constructed low-carbon innovation indicators of listed firms in China spanning 2015 to 2021. This study investigated the impact of climate transition innovations on the default risk, considering the mediation effect of investor attention, total factor productivity, and technology spillovers. The findings suggest that low-carbon innovations can mitigate the default risk of listed firms, as evidenced by three low-carbon innovation indicators. Additionally, the research reveals that the climate innovation effect on default risks was moderated when considering climate policy through heterogenous analysis. Furthermore, instrumental variable regressions using the time costs of innovation support the findings. Lastly, default risk was mitigated through lower levels of investor attention, greater total factor productivity, and technology spillovers.
PSD and Cross-PSD of Responses of Seven Classes of Fractional Vibrations Driven by fGn, fBm, Fractional OU Process, and von Kármán Process
Authors: Li Ming
Published: May 2024

This paper gives its contributions in four stages. First, we propose the analytical expressions of power spectrum density (PSD) responses and cross-PSD responses to seven classes of fractional vibrators driven by fractional Gaussian noise (fGn). Second, we put forward the analytical expressions of PSD and cross-PSD responses to seven classes of fractional vibrators excited by fractional Brownian motion (fBm). Third, we present the analytical expressions of PSD and cross-PSD responses to seven classes of fractional vibrators driven by the fractional Ornstein–Uhlenbeck (OU) process. Fourth, we bring forward the analytical expressions of PSD and cross-PSD responses to seven classes of fractional vibrators excited by the von Kármán process. We show that the statistical dependences of the responses to seven classes of fractional vibrators follow those of the excitation of fGn, fBm, the OU process, or the von Kármán process. We also demonstrate the obvious effects of fractional orders on the responses to seven classes of fractional vibrations. In addition, we newly introduce class VII fractional vibrators, their frequency transfer function, and their impulse response in this research.
Improved Galaxy Morphology Classification with Convolutional Neural Networks
Authors: Urechiatu Raul , Frincu Marc
Published: May 2024

The increased volume of images and galaxies surveyed by recent and upcoming projects consolidates the need for accurate and scalable automated AI-driven classification methods. This paper proposes a new algorithm based on a custom neural network architecture for classifying galaxies from deep space surveys. The convolutional neural network (CNN) presented is trained using 10,000 galaxy images obtained from the Galaxy Zoo 2 dataset. It is designed to categorize galaxies into five distinct classes: completely round smooth, in-between smooth (falling between completely round and cigar-shaped), cigar-shaped smooth, edge-on, and spiral. The performance of the proposed CNN is assessed using a set of metrics such as accuracy, precision, recall, F1 score, and area under the curve. We compare our solution with well-known architectures like ResNet-50, DenseNet, EfficientNet, Inception, MobileNet, and one proposed model for galaxy classification found in the recent literature. The results show an accuracy rate of 96.83%, outperforming existing algorithms.
Hepatitis C Virus E1E2 Structure, Diversity, and Implications for Vaccine Development
Authors: Pierce Brian G. , Felbinger Nathaniel , Metcalf Matthew , Toth Eric A. , Ofek Gilad , Fuerst Thomas R.
Published: May 2024

Hepatitis C virus (HCV) is a major medical health burden and the leading cause of chronic liver disease and cancer worldwide. More than 58 million people are chronically infected with HCV, with 1.5 million new infections occurring each year. An effective HCV vaccine is a major public health and medical need as recognized by the World Health Organization. However, due to the high variability of the virus and its ability to escape the immune response, HCV rapidly accumulates mutations, making vaccine development a formidable challenge. An effective vaccine must elicit broadly neutralizing antibodies (bnAbs) in a consistent fashion. After decades of studies from basic research through clinical development, the antigen of choice is considered the E1E2 envelope glycoprotein due to conserved, broadly neutralizing antigenic domains located in the constituent subunits of E1, E2, and the E1E2 heterodimeric complex itself. The challenge has been elicitation of robust humoral and cellular responses leading to broad virus neutralization due to the relatively low immunogenicity of this antigen. In view of this challenge, structure-based vaccine design approaches to stabilize key antigenic domains have been hampered due to the lack of E1E2 atomic-level resolution structures to guide them. Another challenge has been the development of a delivery platform in which a multivalent form of the antigen can be presented in order to elicit a more robust anti-HCV immune response. Recent nanoparticle vaccines are gaining prominence in the field due to their ability to facilitate a controlled multivalent presentation and trafficking to lymph nodes, where they can interact with both the cellular and humoral components of the immune system. This review focuses on recent advances in understanding the E1E2 heterodimeric structure to facilitate a rational design approach and the potential for development of a multivalent nanoparticle-based HCV E1E2 vaccine. Both aspects are considered important in the development of an effective HCV vaccine that can effectively address viral diversity and escape.
West Nile Virus Subgenomic RNAs Modulate Gene Expression in a Neuronal Cell Line
Authors: Bampali Maria , Kouvela Adamantia , Kesesidis Nikolaos , Kassela Katerina , Dovrolis Nikolas , Karakasiliotis Ioannis
Published: May 2024

Subgenomic flaviviral RNAs (sfRNAs) are small non-coding products of the incomplete degradation of viral genomic RNA. They accumulate during flaviviral infection and have been associated with many functional roles inside the host cell. Studies so far have demonstrated that sfRNA plays a crucial role in determining West Nile virus (WNV) pathogenicity. However, its modulatory role on neuronal homeostasis has not been studied in depth. In this study, we investigated the mechanism of sfRNA biosynthesis and its importance for WNV replication in neuronal cells. We found that sfRNA1 is functionally redundant for both replication and translation of WNV. However, the concurrent absence of sfRNA1 and sfRNA2 species is detrimental for the survival of the virus. Differential expression analysis on RNA-seq data from WT and ΔsfRNA replicon cell lines revealed transcriptional changes induced by sfRNA and identified a number of putative targets. Overall, it was shown that sfRNA contributes to the viral evasion by suppressing the interferon-mediated antiviral response. An additional differential expression analysis among replicon and control Neuro2A cells also clarified the transcriptional changes that support WNV replication in neuronal cells. Increased levels of translation and oxidative phosphorylation, post-translational modification processes, and activated DNA repair pathways were observed in replicon cell lines, while developmental processes such as axonal growth were deficient.
Australia’s states and territories Infection Prevention and Control programs – a comparison study
Authors: Dempsey Kathy , Jain Susan , Bradd Patricia , Clezy Kate , Greenfield David
Published: May 2024

Background: Infection prevention and control (IPC) remains a critical component of delivering quality and safe care. However, clinician understanding of and engagement with IPC remain inconsistent (1–3). In addition, IPC governance, structure and organisation impact on clinician engagement are not well described. Available publications are limited to healthcare-associated infection (HAI) surveillance and do not reflect the broader IPC program (4–6). As Australia establishes a national coordinating body similar to a Centers for Disease Control and Prevention (CDC), a comparison of jurisdictional IPC provides essential contemporary information to inform the national body.
Method: This study examined the characteristics of jurisdictional (states and territories) IPC programs in Australia and was conducted in two phases. Phase one examined outward facing websites likely to be accessed by clinicians, and phase two surveyed jurisdictional programs using a qualitative questionnaire.
Results: Whilst each jurisdiction had accessible website content, this varied considerably in terms of governance, structure, content, ease of navigation, accessibility and visibility. There was a lack of national focus within jurisdictional programs and websites. Four of eight jurisdictions did not have a formal statewide IPC program at the time of the survey. Variance was reported in governance, structures, focus and program elements.
Conclusion: Inconsistent IPC governance and structure demonstrates poorly aligned Australian IPC programs that may contribute to poor clinician understanding and engagement with IPC. Implementing a coordinated and consistent approach to governance, website design and layout would facilitate a consolidated approach to IPC nationally, which may facilitate clinician understanding and engagement. Shaping IPC nationally would also provide solid IPC foundations to support an Australian CDC.

Published: May 2024

Cellular immunotherapy is an innovative cancer treatment method that utilizes the patient’s own immune system to combat tumor cells effectively. Currently, the mainstream therapeutic approaches include chimeric antigen receptor T cell (CAR-T) therapy, T cell receptor gene-modified T cell therapy and chimeric antigen receptor natural killer-cell therapy with CAR-T therapy mostly advanced. Nonetheless, the conventional manufacturing process of this therapy has shortcomings in each step that call for improvement. Marked efforts have been invested for its enhancement while notable progresses achieved in the realm of biomaterials application. With CAR-T therapy as a prime example, the aim of this review is to comprehensively discuss the various biomaterials used in cell immunotherapy, their roles in regulating immune cells, and their potential for breakthroughs in cancer treatment from gene transduction to efficacy enhancement. This article additionally addressed widely adopted animal models for efficacy evaluating.

Published: May 2024

Intervertebral discs (IVDs) have a limited self-regenerative capacity and current strategies for IVD regeneration are unsatisfactory. Recent studies showed that small extracellular vesicles derived from M2 macrophage cells (M2-sEVs) inhibited inflammation by delivery of various bioactive molecules to recipient cells, which indicated that M2-sEVs may offer a therapeutic strategy for the repair of IVDs. Herein, we investigated the roles and mechanisms of M2-sEVs on IVD regeneration. The in vitro results demonstrated that M2-sEVs inhibited pyroptosis, preserved cellular viability, and promoted migration of nucleus pulposus cells (NPCs). Bioinformatics analysis and verification experiments of microRNA (miR) expression showed that miR-221-3p was highly expressed in M2-sEVs. The mechanism of action was explored and indicated that M2-sEVs inhibited pyroptosis of NPCs through transfer of miR-221-3p, which suppressed the expression levels of phosphatase and tensin homolog and NOD-, LRR-, and pyrin domain-containing protein 3. Moreover, we fabricated decellularized ECM-hydrogel (dECM) for sustained release of M2-sEVs, which exhibited biocompatibility and controlled release properties. The in vivo results revealed that dECM-hydrogel containing M2-sEVs (dECM/M2-sEVs) delayed the degeneration of intervertebral disc degeneration (IDD) models. In addition to demonstrating a promising therapeutic for IDD, this study provided valuable data for furthering the understanding of the roles and mechanisms of M2-sEVs in IVD regeneration.

Published: May 2024

The reprogramming of tumor metabolism presents a substantial challenge for effective immunotherapy, playing a crucial role in developing an immunosuppressive microenvironment. In particular, the degradation of the amino acid L-tryptophan (Trp) to kynurenine (Kyn) by indoleamine-pyrrole 2,3-dioxygenase 1 (IDO1) is one of the most clinically validated pathways for immune suppression. Thus, regulating the Trp/Kyn metabolism by IDO1 inhibition represents a promising strategy for enhancing immunotherapy. Herein, metabolism-regulated nanoparticles are prepared through metal coordination-driven assembly of an IDO1 inhibitor (NLG919) and a stimulator of interferon genes (STING) agonist (MSA-2) for enhanced immunotherapy. After intravenous administration, the assembled nanoparticles could efficiently accumulate in tumors, enhancing the bioavailability of NLG919 and down-regulating the metabolism of Trp to Kyn to remodel the immunosuppressive tumor microenvironment. Meanwhile, the released MSA-2 evoked potent STING pathway activation in tumors, triggering an effective immune response. The antitumor immunity induced by nanoparticles significantly inhibited the development of primary and metastatic tumors, as well as B16 melanoma. Overall, this study provided a novel paradigm for enhancing tumor immunotherapy through synergistic amino acid metabolism and STING pathway activation.

Authors: Qu Yanlin , Zhang Guanran , Wu Zhenyu , Luo Huihuan , Chen Renjie , Jia Huixun , Sun Xiaodong
Published: May 2024

Background:
The relationship between socioeconomic status (SES) inequity and incident age-related macular degeneration (AMD) remains unclear. We aim to investigate whether low SES increases the risk of AMD and to explore the effect of a healthy lifestyle on this association.
Methods:
This prospective cohort study included 316,663 UK Biobank individuals. SES inequity was identified via latent class analysis using education, household income, and occupational status. Healthy lifestyle score was calculated based on smoking, alcohol drinking, and physical activity (PA). Incident AMD was defined according to diagnosis records. Cox proportional hazards models were used to evaluate the relationship of low SES and AMD. Interrelationships of healthy lifestyle score on SES–AMD association were explored, including modification, mediation, and joint effects.
Results:
During the average 12.2 years of follow-up, 6,355 AMD cases were diagnosed. Participants with medium SES (hazard ratio: 1.10 [95% confidence interval (CI) 1.01 to 1.21]) and low SES (hazard ratio: 1.22 [95% CI 1.11 to 1.34]) had an increased risk of incident AMD compared to participants with high SES. PA significantly affected this association. Moreover, the association between low SES and AMD was significantly mediated (11.3%, 95% CI: 6.56 to 23.0) by smoking. Similarly, alcohol drinking suppressed (9.59%, 95% CI: 4.00 to 23.2) the association between high SES and AMD. Besides, a significant joint effect of SES and healthy lifestyle score was found.
Conclusions:
We provide further evidence for the relationship of socioeconomic inequity, healthy lifestyle, and incident AMD. Future public health strategies should aim to reduce socioeconomic inequity to prevent AMD.
Effectiveness of Chemical Oxygen Demand as an Indicator of Organic Pollution in Aquatic Environments
Authors: Lv Zongqing , Ran Xiangbin , Liu Jun , Feng Yao , Zhong Xiaosong , Jiao Nianzhi
Published: May 2024

The chemical oxygen demand (COD) is an essential indicator of organic pollution that represents the amount of bulk carbon in water. COD is strongly correlated with nutrient cycles and other pollutants in the environment, but it has a limited ability to quantify the amount of organic carbon (OC), of which a large proportion is made up of refractory dissolved organic carbon (RDOC) and is a potential carbon sink. Moreover, the biodegradability of OC in terms of its fate and destination should be explored, as well as how this is reflected by COD. Methods based on particle size, spectroscopy, and isotopic tracing are expected to help with deciphering the bioavailability of COD-responsive OC and explore the processes of biogeochemical cycles. As the pressure on the environment from anthropogenic inputs increases, understanding the bioavailability of OC associated with COD will help with developing more precise scientific indicators for environmental monitoring and identifying how new tools will increase knowledge of the carbon cycle. In this review, we discuss the application, scope, means, and advances of COD measurement. Based on data in the literature, we estimate the global RDOC stock and assess the impact of anthropogenic RDOC on the carbon cycle in offshore bays. This review presents new insights into the behavior of OC in aquatic environments and a potential pathway for ocean negative carbon emissions by expanding the role of RDOC as a carbon sink to offset the effect of anthropogenic carbon emissions.

Published: May 2024

Our research focuses on identifying implicit ways of expressing evaluation and identifying the role of the author in media texts about culture. In order to analyze the category of evaluation we took Russian-language and German-language articles, which have a common newsworthy occurrence: the 130th anniversary of the birth of Marina Tsvetaeva. In the course of the study the publications were analyzed in terms of the presence of implicit evaluations and the linguistic means by which they are carried out. As a result of the study, it turned out that the evaluation has a predominantly positive character on the part of both Russian and German-speaking publications. The implicit evaluation of the Russian-language media texts was expressed at the level of grammar, while the German-language media texts used metaphors and epithets. We also analyzed publications for the presence of the author in the media text according to two parameters proposed by T. V. Shmeleva: author identification and the degree of media text complexity.

The development of creative industries in modern conditions is a factor in revitalizing re-gional economies around the world. In Russia, the creation of Creative Industries Schools based on educational institutions subordinated to regional departments and Ministries of Culture has become an important tool for the development of creative industries. These schools not only train personnel for the formation of human potential in creative industries, but also act as an important tool for economic and spatial development of the region. In this article, on the basis of collected and sys-tematized data on commercial activity of creative industries enterprises in Tomsk region by cities, as well as analysis of the experience of creating one of the schools in Tomsk, we develop models of "translucent box", reflecting the impact of the School of Creative Industries as a whole, as well as its individual projects - "Sibirskaya Ne_provincia" and "Creative landing" - on the economy of the region. The results of the study show that from the position of the development of the economic space of creative industries in the region the center, the city of the "second echelon" and other cities are distinguished. Creative industries are created mainly in the form of individual enterprises, the key types of creative industries, which create new business production of software and computer games, film industry, fashion, design, jewelry, as well as education. The projects of the School of Creative Industries have a positive impact on the spatial development of the region through the realization of creative and social projects. This article will be useful for representatives of the creative industries community, including project offices, Creative Industries Schools, educational organizations, city, and regional administrations, as well as creative clusters to develop a system of cooperation and collab-oration. The results will be presented at the St. Petersburg International Economic Forum 2023 and at the Festival-Forum "Russian Creative Week 2023".

Authors:   Vladimir State Universitynamed after Alexander and Nikolay Stoletovs, Bykova M. L.
Published: May 2024

This article examines current approaches to understanding the economic security of the regions of the Russian Federation. The analysis of the works of domestic and foreign authors related to the research problem allowed identifying the special role of competent management of economic security in the effective development of territories. Despite the exceptional role of economic security, there are no clear strategies for managing sustainable development at the meso-level. The proposed system for assessing economic security at the level of the country's subjects is based on a systematic approach, which is the methodological basis of the entire study. Statistical parameters determined based on Rosstat data on the directions characterizing the level of economic security at the national level were selected as indicators of the analysis of economic security at the meso-level. In the study, clusters were formed according to the values of mesoparameters in 2022. The use of cluster analysis made it possible to identify regions with similarities according to the proposed criteria for assessing economic security at the level of the subjects of the Russian Federation. The number of groups to split was determined by the Sturgess formula, and the calculated results were also confirmed by graphical analysis of the vertical dendrogram. The graph of the average characteristics of the identi-fied clusters made it possible to analyze similar features of certain regional groups. The study also proposed directions for improving economic security, considering the identified features.

The tasks are aimed at emphasizing the relevance of the issue under study against the background of digitalization in all spheres of ac-tivity, as well as the expediency of using influence marketing in expanding brand communications with target audiences and forming a "sales funnel". As a result of monitoring Internet resources, the features of the use of influence marketing by companies of the Rostov region and Rostov-on-Don in comparison with the regions of the country are presented graphically, content segments, regularity and frequency of work in social networks are highlighted. It is determined that Rostov companies use various types of content, but it does not find a response from the target audience due to the low involvement of users in the "history" of the brand, which is primarily due to the lack of a professional approach to attracting opinion leaders who strongly influence the presentation of the brand in the digital environment and attracting audiences. The main online platforms are also highlighted, which show relative efficiency and high conversion when using influencer marketing by Rostov companies in the digital environment. The study of the use of influencer marketing predetermined the develop-ment of a content plan for the implementation of an influencer marketing strategy, from setting goals, choosing opinion leaders to implementation and obtaining effectiveness. A survey was con-ducted among representatives of 30 companies on the choice of an opinion leader and use in brand promotion. As it turned out, it is bloggers who have an authoritative influence on the choice of brands in various fields, including cafes, restaurants, places to relax and buy goods, beauty salons, sports clubs, medical institutions, etc. A content plan adapted to the activities of small and medium-sized businesses was tested in a commercial medical institution in Rostov-on-Don in 2023.

THE EVOLUTION OF NURSING AS A PROFESSION IN HEALTHCARE
Authors: Salihu Kushtrim
Published: May 2024

Currently, nursing stands as a highly coveted profession drawing significant attention. While its roots can be traced back to ancient times, the formal recognition of nursing as a profession, labeled as such, has only emerged in recent decades. Defined as both a science and an art grounded in evidence, nursing is progressively assuming more significant roles within the healthcare and biomedical realms. The profession’s evolution is intricately linked with advancements in science, technology, and research, which have translated into tangible practices within the healthcare system. Offering both undergraduate and graduate nursing programs elevates the level of responsibility among nurses. However, this advancement lacks proper systematization and acknowledgment of educational standards within the healthcare sector. Future challenges encompass meeting the increasing healthcare demands spurred by longer life expectancies and population growth, alongside facilitating professional mobility within EU nations. Factors such as enhanced financial stability and improved working conditions contribute to the outflow of nurses from the region. Proposed solutions include establishing adaptable mobile teams, prioritizing patient education and preventative measures, integrating LED clinics/facilities, and introducing supportive robotic technologies. Nurses play a pivotal role in delivering care and advocating for health equity, emphasizing the necessity of fostering collaborative partnerships for the future sustainability of healthcare systems.
