Maneuvering Decision Making Based on Cloud Modeling Algorithm for UAV Evasion–Pursuit Game

When facing problems in the aerial pursuit game, most of the current unmanned aerial vehicles (UAVs) have good maneuverability performance, but it is difficult to utilize the overload maneuverability of UAVs properly; further, UAVs tend to be more costly, and it is often difficult to effectively prevent the enemy from reaching the tailgating position behind the UAV in the aerial pursuit game. Therefore, there is a pressing need for a maneuvering algorithm that can effectively allow a UAV to quickly protect itself in a disadvantageous position, stably and effectively select a maneuver with the maneuvering algorithm, and stably and effectively establish an advantage by moving to an advantageous position. Therefore, this paper establishes a cloud model-based UAV-maneuvering aerial pursuit decision-making model based on pursuit-and-evasion game positions. Based on the evaluation of the latter, when the UAV is at a disadvantage, we use the constructed defensive maneuver expert pool to abandon the disadvantageous position. When the UAV is at an advantage, we use cloud model-based pursuit-and-evasion game maneuvering decision making to establish an advantageous position. According to the results of the simulation examples, the maneuvering decision-making method designed in this paper confirms that the UAV can quickly abandon its position and establish an advantage in case of parity or disadvantage and that it can also stably establish a tail-chasing position in case of advantage.

Design and application of distal radial artery hemostat

Transradial approach is the classical access for coronary angiography and percutaneous coronary intervention (PCI). With the increase in the number of interventional procedures, some disadvantages of the transradial approach have also been found, it is easy to lead to various complications, such as radial artery occlusion, radial nerve injury, and puncture difficulties after radial artery spasm. Therefore, some experts put forward the approach of distal radial artery approach for interventional therapy, which has the advantages of convenient positioning, easy postoperative hemostasis, less damage to the proximal radial artery and improving patients' comfort. However, there is no special distal radial artery hemostat in clinic, which limits the development of this approach to a certain extent. Therefore, based on the principles of anatomy and physics, cardiovascular physician at Jiading District District Central Hospital in Shanghai designed and invented a distal radial artery hemostatic device, which is convenient for clinical hemostasis of distal radial artery puncture, and obtained the National Utility Model Patent (patent number: ZL 2021 2 2097829.6). The hemostatic device consists of a glove body with a silicone gasket protruding towards the skin on the inner surface and a binding component. The patient's hand is inserted into the glove body, and after being fixed by the restraint component, the silicone gasket can effectively compress the location of the radial artery puncture point, and play a good hemostatic effect with less pressure, avoid the common complications of proximal radial artery hemostatic, and reduce the discomfort of the patient. Has good application value.

সুন্দরবনের জল ও জঙ্গলে বাংলাদেশের মুক্তিযুদ্ধ: নব্য-নির্ধারণবাদী বিশ্লেষণ

In the Liberation War of Bangladesh, its geographical features were influential in many ways on the activities of the freedom fighters and their opposing forces. This is even more true in the case of the liberation war of the Sundarbans in water and jungle. In June 1971, Under Lt. Ziauddin's leadership, freedom fighter bases were established inside the Sundarbans. The group is organised in the deep forest, accepting and in some cases overcoming the various obstacles of nature. Using the natural obstacles to their advantage, they again engaged the Pakistani troops and their allied forces in the immediate area. Using their positional advantage, these freedom fighters played an effective role in sending refugees and trainees across the border. On the other hand, the freedom fighters in Sundarbans were used as a transit for many of the freedom fighters who came from July with training and weapons to the interior of the country, especially in the Khulna-Barisal region. This article analyses such activities of the Sundarbans freedom fighters in a neo-deterministic trend.

Motivations for environmental social responsibility in ecuadorian banana companies

The corporate image, good business reputation, competitive advantage, business growth, and market positioning are motivational elements for environmental and social responsibility (ESR), including the organization's commitment to environmental care for its economic activity and the certifications of quality and environmental sustainability in agricultural companies. This work determined the elements of the motivation for the environmental and social responsibility of the Ecuadorian banana companies. The method applied is a quantitative approach. Under a non-experimental descriptive work design with a correlational scope, the reliability analysis was carried out with Cronbach's Alpha, giving a value of 0.98 to the 22-item instrument applied to 86 small banana companies. The final results prove a high relationship between the motivations of the banana companies and environmental social responsibility p> 0.9.

Research on laser induced plasma ignition of gas oxygen/methane

Laser-induced plasma ignition is a new ignition method to achieve stable and reliable ignition of liquid rocket engines. It has the advantages of accurate and controllable ignition position, broadening ignition lean-burn limit and small disturbance to flow field. In this paper, the laser ignition process and combustion characteristics of gas oxygen/gas methane under rocket engine conditions are studied from four aspects, namely different ignition positions, ignition energy, fuel-oxygen momentum ratio and chamber pressure. Using a high-speed camera, the dynamic process of ignition was captured by the shadow method, and the generation and propagation of laser-induced flame nuclei were recorded. The results show that at the airflow velocity of 300–400 m/s, the time required for the flame kernel to develop to the entire combustion chamber is about 300 μs, and the time for the flame to reach a steady state is tens of milliseconds. When the ignition energy is increased by 1.5 times, the time required for the flame kernel to develop from the recirculation zone to the mainstream zone is shortened to 1/3 of the original; with the increase of the fuel-oxygen momentum ratio, the shape of the initial flame kernel changes from round to oval, and the development speed of the flame kernel also increases. The fuel-oxygen momentum ratio increases from 0.59 to 2.75, and the time required for the flame kernel to develop from the recirculation zone to the mainstream zone decreases from 167 μs to 56 μs＀ Except chamber pressure, other factors have no effect on the pressure rise rate of the ignition process, and the higher the chamber pressure, the faster the pressure rise rate; in order to avoid deflagration, the shear layer is more suitable as the ignition position. With the increase of ignition energy, fuel-oxygen momentum ratio and chamber pressure, the development speed of flame kernel increases, but the shape and development process of flame kernel will be different under the influence of different factors.

Differential Interaction: Development of Cross-border Data Flow Governance Mechanisms In Asean

Cross-border data flows, which are fueled by the digital economy, increase the productivity and efficiency of the global economy. The cross-border movement of data has a direct influence on both national security and the growth of the digital economy.Therefore, in order to deal with the security and development issues brought on by the digital geopolitical game, on the one hand, ASEAN focuses on the overall growth of the digital economy and data security,on the other hand, it continues to encourage the spread of the innovative "ASEAN+" governance model and actively participates in the creation of regulations for the digital world. The digital geostrategic competition between large nations is skillfully employed, on the other hand, to aim for a more advantageous position in order to mitigate the negative impacts brought on by mechanism fragmentation. A governance mechanism for cross-border data flow is built using the relational governance concept of “self” and “other” interaction.The negotiating cost and compliance cost will be decreased through the adaptable interplay between mechanism spillover and mechanism internalization, expanding the digital economy in the ASEAN region and enhancing competitive advantages on a worldwide scale.

Information and psychological warfare in the context of the war between Azerbaijan and Armenia

The purpose of the paper is to highlight the development of information-psychological warfare, its history, concepts, technologies and methods, which are one of the most important areas of work in the field of international relations. The concept of ‘information warfare’ has concentrated a number of phenomena from the sphere of mass communications and during the 20th century was called various terms, such as ‘disinformation’, ‘propaganda’, ‘psychological warfare’, ‘psychological operations’.
 Within the scope of the study, the importance of psychological warfare in today’s context has been examined using the example of Azerbaijan and Armenia. It has been emphasized how Armenia effectively employed psychological warfare tactics and propaganda to gain an advantageous position in the late 20th century. In the early 21st century, the significance of Azerbaijan gaining a superior position in psychological warfare and using propaganda effectively has been discussed. Additionally, the article delves into the importance of using white propaganda during psychological warfare and the drawbacks of black propaganda within the context of the psychological warfare between Azerbaijan and Armenia.
 The novelty of the paper lies in a comprehensive analysis of information and psychological warfare and operations in the context of the Azerbaijan-Armenian conflict.
 Conclusions. In the 20th century information and psychological warfare and operations became part of the military policy of states. Now, due to the current situation on the world stage, the methods and means of conducting information warfare are changing and every year they are reaching a higher level. It can also be stated that in the 21st century, information wars have become more widespread. In summary, the historical context and evolution of information warfare demonstrate its enduring significance as a tool for states to achieve their strategic and political goals. As technology and global politics continue to evolve, information warfare is likely to remain a key component of statecraft and international relations.

ERP systems in small and medium-sized enterprises: Barriers and prospects

ERP systems are among the most effective tools for managing small and medium-sized enterprises. However, the mechanisms for introducing such systems have not yet been comprehensively developed in relevant theoretical and empirical works. The article examines the ERP systems market in Russia, compares their benefits and drawbacks and delves into the details of implementing such systems in small and medium-sized enterprises (SMEs). The process approach to describing the stages of ERP system implementation constitutes the methodological basis of the research. The study has a quantitative design; the empirical data were obtained from 103 respondents in the period between June–October 2023, as well as from the Russian Federal State Statistics Service (Rosstat) for 2016–2021. We have found that 1C Company can boast the most advantageous position in the Russian ERP systems market for small and medium-sized businesses. The comparative analysis of the leading Russian ERP solutions confirms that 1C ERP is the most adequate product for SMEs in terms of its functionality, price, and speed of implementation. Resultantly, we have proposed an integrated model of ERP system for SMEs that can be adopted in a fast and effective manner, which is critically important for this sector of the economy. The approach can also be seen as guidelines to implementing an ERP system in small and medium-sized enterprises. The research findings highlight the importance of SMEs digital transformation through ERP systems.

Divergent molecular strategies drive evolutionary adaptation to competitive fitness in biofilm formation.

Biofilm is a group of heterogeneously structured and densely packed bacteria with limited access to nutrients and oxygen. These intrinsic features can allow a mono-species biofilm to diversify into polymorphic subpopulations, determining the overall community's adaptive capability to changing ecological niches. However, the specific biological functions underlying biofilm diversification and fitness adaptation are poorly demonstrated. Here, we launched and monitored the experimental evolution of Pseudomonas aeruginosa biofilms, finding that two divergent molecular trajectories were adopted for adaptation to higher competitive fitness in biofilm formation: one involved hijacking bacteriophage superinfection to aggressively inhibit kin competitors, whereas the other induced a subtle change in cyclic dimeric guanosine monophosphate signaling to gain a positional advantage via enhanced early biofilm adhesion. Bioinformatics analyses implicated that similar evolutionary strategies were prevalent among clinical P. aeruginosa strains, indicative of parallelism between natural and experimental evolution. Divergence in the molecular bases illustrated the adaptive values of genomic plasticity for gaining competitive fitness in biofilm formation. Finally, we demonstrated that these fitness-adaptive mutations reduced bacterial virulence. Our findings revealed how the mutations intrinsically generated from the biofilm environment influence the evolution of P. aeruginosa.

Brief interventions for smoking and alcohol associated with the COVID-19 pandemic: a population survey in England

BackgroundFollowing the onset of the COVID-19 pandemic, in March 2020 health care delivery underwent considerable changes. It is unclear how this may have affected the delivery of Brief Interventions (BIs) for smoking and alcohol. We examined the impact of the COVID-19 pandemic on the receipt of BIs for smoking and alcohol in primary care in England and whether certain priority groups (e.g., less advantaged socioeconomic positions, or a history of a mental health condition) were differentially affected.MethodsWe used nationally representative data from a monthly cross-sectional survey in England between 03/2014 and 06/2022. Monthly trends in the receipt of BIs for smoking and alcohol were examined using generalised additive models among adults who smoked in the past-year (weighted N = 31,390) and those using alcohol at increasing and higher risk levels (AUDIT score 38, weighted N = 22,386), respectively. Interactions were tested between social grade and the change in slope after the onset of the COVID-19 pandemic, and results reported stratified by social grade. Further logistic regression models assessed whether changes in the of receipt of BIs for smoking and alcohol, respectively, from 12/2016 to 01/2017 and 10/2020 to 06/2022 (or 03/2022 in the case of BIs for alcohol), depended on history of a mental health condition.ResultsThe receipt of smoking BIs declined from an average prevalence of 31.8% (95%CI 29.4–35.0) pre-March 2020 to 24.4% (95%CI 23.5–25.4) post-March 2020. The best-fitting model found that after March 2020 there was a 12-month decline before stabilising by June 2022 in social grade ABC1 at a lower level (~ 20%) and rebounding among social grade C2DE (~ 27%). Receipt of BIs for alcohol was low (overall: 4.1%, 95%CI 3.9–4.4) and the prevalence was similar pre- and post-March 2020.ConclusionsThe receipt of BIs for smoking declined following March 2020 but rebounded among priority socioeconomic groups of people who smoked. BIs for alcohol among those who use alcohol at increasing and higher risk levels were low and there was no appreciable change over time. Maintaining higher BI delivery among socioeconomic and mental health priority groups of smokers and increasing and higher risk alcohol users is important to support reductions in smoking and alcohol related inequalities.

Investigation of the Sicilian Defense: Winning rates and strategic discrimination

Chess games demonstrate players’ ability to envision the situation on a large scale, cope with variations, and take precautions. It’s been proven statistically and mathematically that the white sides are more likely to win due to offensive advantage. Nonetheless, utilizing numerous defensive gambits, the black enhances its chances of succeeding, among which the Sicilian defense ranks the top. Characterized by asymmetrical arrangements, the Sicilian defense carves the path for the queen while not waiving to occupy central positional advantages. Dating back to its origin in the 16th century, it has prevailed since the mid-20th century and has now developed its most complex variations in response to white’s first move, “e4”. In this research, whether there is a significant difference in the winning rate of each variation is examined, and the payoffs for them are evaluated mathematically for a theoretically optimized strategy.

Sites of significance

ABSTRACT Late 19th-century Singapore is considered the centre for the printing and distribution of Muslim-Malay lithographed texts in the Malay archipelago. In 1890, the island’s print output was approximately six million pages, with many of these printed from lithography. Thus informed, our recent readings of Singapore’s role in regional histories of the printed book tend to locate its prominence along contemporary, national lines – this is anachronistic. The island, historically, was neither nation nor state, but a British colonial settlement. Singapore’s advantageous geographical position certainly established it as a prominent site for book production and distribution. However, the existing corpus of lithographed publications, printed at multiple localities, indicate a broader range of regional locations involved in Muslim printing. These texts, from mushaf to syair, often feature printed defects and paratextual marks on their pages. Informed by approaches from analytical bibliography and printing history, the materiality of these marks and defects can be ‘read’ to identify specific print production techniques. These, in turn, suggest printing methods that were common in British and Dutch territories, and beyond – an indication of the mobility of techniques, materials, and practitioners within the lithographic trade, and the collaborative nature of print enterprises in the Malay world. By discussing these printed marks, this article will (a) re-situate and revise our understanding of interactions and practices within the Muslim-Malay lithographic printing trade; and (b) posit the notion that late 19th-century Singapore is not the locus, but one of several sites of significance within a regional ‘constellation’ of printing activity.

Research on the Innovation Driven Growth Path of Developing Economies in the Context of Globalization

This study focuses on the challenges and opportunities faced by developing economies in a globalizing world and explores the path to innovation-driven growth. According to research, globalization presents developing economies with tremendous opportunities for market and technological exchange, but it also brings intense international competition and pressure to upgrade their industries. Case studies, such as the success of South Korea and the challenges of Argentina, demonstrate the importance of innovation- driven growth strategies. To cope with the challenges brought by globalization, it is suggested that developing economies need to enhance their innovation capabilities and economic competitiveness by strengthening international cooperation, increasing education investment, and improving the institutional environment. Through these strategies, these economies can be transformed into more efficient and sustainable development models, thereby occupying a more advantageous position in the global economy.

Regional aspects of the restructuring of tourist flows in Europe in the 21st century

The impact of the COVID-19 pandemic on global tourism is not limited to the crisis in the tourism industry. The pandemic was accompanied by a spatial restructuring of tourist flows. The purpose of the study is to identify the features of this restructuring at the regional level of European countries under the influence of the pandemic and geopolitical factors. The information base for the study is statistics of tourist arrivals for 427 regions of European countries in the period from 2003 to 2022. The entire time interval of the study, in accordance with the peculiarities of the spatial restructuring of tourist flows, is divided into three periods (pre-pandemic, pandemic and the beginning of recovery from the pandemic). The analysis was carried out using a cartographic research method. The main trend of spatial restructuring of tourist flows from 2003 to 2019. was their partial redistribution in favor of the regions of the countries of the eastern part of Europe (post-socialist countries) and Turkey. During the pandemic (2020–2021), the greatest reduction in tourist flow characterized countries specializing in inbound tourism. Countries that managed to move towards increasing domestic tourist flows (including Russia) found themselves in a more advantageous position. In 2022, within foreign Europe, due to the persistence of sanitary restrictions in a number of countries at the beginning of the year, it was possible to observe a temporary redistribution of tourist flows from the central part of Europe to its periphery.

Two-dimensional SPdAZ2 (A = Si, Ge; Z = N, P, As) monolayers with an intrinsic electric field for high-performance photocatalysis.

Two-dimensional materials exhibiting exceptional photocatalytic properties and a low carrier recombination rate have garnered significant attention. However, such attributes are relatively scarce among conventional two-dimensional materials. Two-dimensional Janus materials, owing to their intrinsic electric field, hold substantial promise in the realm of photocatalysis. In this study, we conducted a comprehensive investigation of the electronic, optical and photocatalytic properties, as well as the carrier mobility of SPdAZ2 (A = Si, Ge; Z = N, P, As) monolayers employing first-principles calculations. Employing the HSE06 hybrid density functional, we discovered that all six structures exhibit semiconductor characteristics with indirect band gaps under equilibrium conditions. Notably, SPdSiP2, SPdSiAs2, and SPdGeP2 monolayers displayed advantageous band edge positions, facilitating effective photocatalytic water decomposition. Furthermore, we computed the carrier mobility of SPdAZ2 monolayers, revealing significant variations in the electron and hole mobility along the same direction, which enhances the effective separation of electrons and holes. Finally, we explored the impact of biaxial strain and an applied electric field on the electronic properties, photocatalysis, and light absorption of SPdAZ2 monolayers. These compelling features underscore the broad potential applications of SPdAZ2 (A = Si, Ge; Z = N, P, As) monolayers in the realm of photocatalytic water decomposition.

Board Interlock Networks and Corporate Low-Carbon Innovation in China: Does Position Matter?

Through combining the resource dependence theory and social network theory, this study sheds light on how two major kinds of interlocking network positions—central network position and structural holes position—drive corporate low-carbon innovation. We consider the mediating effect of information asymmetry and knowledge absorptive capacity to reap benefits from occupying the two advantageous network positions. We have empirically investigated a sample of 3365 listed firms over the period of 2009–2018 drawn from China, the largest emerging market economy as well as the biggest carbon dioxide emitter. Our main results show that either holding a central network position or spanning a structural holes position plays a significant role in stimulating low-carbon technologies, and the promotion effect can be partially channeled through downward information asymmetry and upward knowledge absorptive capacity. Our findings differ from earlier work because of our emphasis on network position, and our specific focus on corporate low-carbon innovation and China's unique setting, rather than network size, greenhouse gas emissions, and developed economies. This study also provides significant implications for executives striving to improve firms’ low-carbon innovation performance, and for policymakers seeking ways to fulfill the mission of carbon dioxide abatement.
