Economic Load Dispatch Problem Analysis Based on Modified Moth Flame Optimizer (MMFO) Considering Emission and Wind Power

In electrical power system engineering, the economic load dispatch (ELD) problem is a critical issue for fuel cost minimization. This ELD problem is often characterized by non-convexity and subject to multiple constraints. These constraints include valve-point loading effects (VPLEs), generator limits, emissions, and wind power integration. In this study, both emission constraints and wind power are incorporated into the ELD problem formulation, with the influence of wind power quantified using the incomplete gamma function (IGF). This study proposes a novel metaheuristic algorithm, the modified moth flame optimization (MMFO), which improves the traditional moth flame optimization (MFO) algorithm through an innovative flame selection process and adaptive adjustment of the spiral length. MMFO is a population-based technique that leverages the intelligent behavior of flames to effectively search for the global optimum, making it particularly suited for solving the ELD problem. To demonstrate the efficacy of MMFO in addressing the ELD problem, the algorithm is applied to four well-known test systems. Results show that MMFO outperforms other methods in terms of solution quality, speed, minimum fuel cost, and convergence rate. Furthermore, statistical analysis validates the reliability, robustness, and consistency of the proposed optimizer, as evidenced by the consistently low fitness values across iterations.

The impact of inclusion in the MSCI EM index on firms' investment efficiency：Evidence from China

This paper investigates the impact of A-share inclusion in the MSCI index on corporate investment efficiency. Using the inclusion of A-shares in the MSCI index on June 1, 2018 as a quasi-natural experiment, the results of the PSM-DID model show that the inclusion of A-shares in the MSCI index significantly reduces corporate investment efficiency. Further analysis reveals that inefficient investment mainly occurs in over-invested firms, non-state-owned firms, and firms audited by Big 4 accounting firms. Firms with low managerial ownership and high degree of surplus management are more likely to overinvest after A-share inclusion in the MSCI index, which leads to a decrease in investment efficiency. Firms with high analyst attention and low equity checks and balances increase their investment after A-share inclusion in the MSCI index, and the influences of decision-making power and control can be the triggers to reduce investment efficiency.

The Holistic MAP to Athletic Wellness: A Narrative Review

You can’t use an old map to explore a new world. —Albert Einstein We are at a fork in the evolutionary road to athletic wellness. While elite athletes are achieving unsurpassed magnificence in strength, endurance, power, and skill, much of our population is experiencing a devolution from poor lifestyle choices that negatively influence both human and planetary health. The alarming descent to a lesser state of collective health puts most of our sedentary population at greater risk of injury, disease, dysfunction, and chronic pain. The father of sports medicine, Herodicus, was the first known physician to recommend exercise for the treatment of disease, recognizing its powerful influence on quality of life and health span. Athletic participation is linked with improved physical and mental health, as well as reduced obesity, disability, and disease. However, sports may also result in physical, psychological, social, athletic, professional, and financial repercussions.1 The international scientific community has rallied with tremendous research over the past decades to promote sustainable athletic participation and healthy active living. While tremendous efforts have been launched to engage in this challenging endeavor, a significant problem remains due to the multifactorial nature of athletic injuries. The full potential for body-mind-spirit resilience and wellness is achieved through the balance of all interdependent components, considering all possible biological, psychological, social, and spiritual factors influencing each athlete to establish an individualized, holistic mindset, agility, and personalization (MAP) approach toward injury-free sports and active living.

Analyzing China's Global Influence Through the Belt and Road Initiative: A Case Study of the Pakistan-China Energy and Economic Corridor

This article attempts to explain how China has used the Belt and Road initiative (BRI) to increase its economic power and geopolitical influence by analyzing the advantages and disadvantages of the Pakistan-China Energy and Economic Corridor (PCEEC). During this process, China has gained actual control over these countries' strategic resources and transportation hubs by providing debt and building infrastructure. This control not only improves Chinas international trade volume and economic development, but also enables it to influence the policy formulation and sovereign decision-making of these countries. The expansion of its economic and political influence has given China a greater voice in regional and international affairs in order to more effectively promote international agendas and rule-making that are in line with its own interests. Therefore, China has successfully improved its global influence and leadership through a combination of economic investment and political strategies, but has also aroused international attention and discussion on sovereign independence and regional balance.

Problems of Ensuring the Independence of the Judiciary in Modern Conditions

The principle of independence of the judiciary and guarantees for its implementation are considered through the prism of the institutional structure and functioning of the judicial system. The influence of presidential power on the formation of the judiciary is studied, which does not fully contribute to ensuring the independence of the court. The role of qualification boards of judges as bodies of the judicial community in the formation of the judiciary is considered. Particular attention is paid to the formation of the court apparatus, which ensures the administration of justice, creates additional guarantees for the independence of the judiciary. The results of the study show the influence of state authorities, primarily the presidential, on the independence of judges in the formation of the judiciary and the court apparatus. Proposals aimed at creating additional guarantees for ensuring the independence of the judiciary in the selection of judges and the appointment of court staff are substantiated.

The Economic and Geopolitical Significance of the Brics Nations: A Comparative Analysis of Their Global Influence in the 21st Century

The research investigates how BRICS (Brazil, Russia, India, China, and South Africa) influence global economics and political leadership while noting the opportunities and obstacles the alliance encounters. As a powerful influence in finance and trade globally, BRICS confronts the Western institutions that used to dominate. The collective has challenges from its members' vast economic and political variation, even with important milestones like the setup of the New Development Bank. In addition, outside influences from political tensions, mainly with the G7 and global competition, obstruct detailed cooperation. This research examines how the future of BRICS might develop, especially with the BRICS+ initiative, which is designed to include members from the Global South. The growth shows BRICS's purpose to shape global governance more strongly. The study recognizes a requirement for better political and economic integration among BRICS and points out that greater collaboration within the group may promote sustainable growth and financial strength. Limitations in methodology and data quality are recognized along with time constraints relating to the trustworthiness of macroeconomic information from the BRICS countries. This study ends by suggesting ways to enhance BRICS collaboration and identifies new research inquiries regarding the alliance's future direction and its impact on a more diverse world order

Influence of discharge power and grid structure on an RF-biased ion thruster

The RF-biased ion thruster applies radio-frequency (RF) power on the grid system, which can extract both ions and electrons to achieve self-neutralization. The performance of the RF-biased ion thruster is significantly influenced by the structure of the grid system and the discharge power since these factors play a crucial role in determining the focusing condition of the grid system. In this paper, the influence of discharge power and grid structure on the RF-biased ion thruster’s voltage parameters is investigated. According to the screen grid voltage waveform results under different discharge power and grid structure, the relationship between self-bias voltage and RF voltage is acquired. In order to explain the different waveform variations, the impacts of the direct impingement current as well as the oscillation of the upstream sheath voltage are considered in the theoretical calculation for self-bias voltage. It has been found that the opposite oscillation of the upstream sheath voltage is the primary reason for the decline in self-bias voltage. Moreover, the mechanisms through which discharge power and grid structure influence the self-bias voltage are explained in terms of their impact on upstream sheath oscillation. Several methods for increasing the self-bias voltage in RF-biased ion thrusters are also proposed.

Aligning local governance with SDGs: a study of local government systems in Pakistan

ABSTRACT This study examines the experiences of local government councilors between 2013–2020 in four provinces of Pakistan. The study addresses three key questions: Firstly, it investigates the differences and commonalities in the local government structures across provinces and explores the potential for synchronization to enhance the implementation of Sustainable Development Goals (SDGs) at the local level. Secondly, it examines the main challenges local councilors face in effectively delivering basic services, including water, sanitation, health, education, waste management, and transport, within both rural and urban contexts. Lastly, the study analyses the necessary changes or reforms at the provincial level within the existing local government system in rural and urban areas to ensure the delivery of basic services in alignment with SDGs. The findings reveal that a powerful bureaucracy and political influence at the intermediate to upper levels of the government hierarchy exert significant control over administrative, fiscal, and political.

Investigation of optical fiber line with a positive transmission ratio of analog microwave signal

The influence of optical radiation power on the one-decibel compression point, harmonic distortion and dynamic range due to interference in a fiber-optic transmission line of an ultra-high frequency (microwave) signal has been studied. The line had a positive microwave signal transmission coefficient, and there were no amplification elements between the input and output. The amplification effect was achieved through the use of increased power of the carrier optical radiation and a photodetector with a high photocurrent. It has been shown that an increase in optical radiation power leads to a decrease in one-dB compression power and an increase in harmonic distortion, but an increase in optical radiation power does not lead to a change in the dynamic range of interference. It was found that the dynamic range free from interference was about 85…87 dB.

It investigates the decisive role curators play in shaping the influence of these power structures and proposes strategies for enhancing curatorial leadership and curatorial capabilities. The aim is to provide valuable insights and references for art institutions and curators in China, encouraging continuous self-improvement and capacity building among curators to contribute effectively to the sustainable development of the contemporary art ecosystem in China.

On the Piezoelectric Properties of Zinc Oxide Thin Films Synthesized by Plasma Assisted DC Sputter Deposition

AbstractThis work presents a study of piezoelectric zinc oxide (ZnO) thin films deposited by a novel post‐reactive sputtering method. The process utilizes a rotating drum with DC magnetron sputtering deposition onto substrates with subsequent DC plasma‐assisted oxidation of the deposited metal to metal oxide. The paper analyzes the influence of plasmaassisted magnetron sputtering (PA‐MS) deposition parameters (O2 plasma source power, O2 flow, and Ar flow) on the morphological, structural, optical, and piezoelectric properties of ZnO thin films. Design of experiments has been utilized to evaluate the role of these parameters on the growth rate (rg) and the properties of resulting films. Results indicate a predominant influence of the plasma power on the rg over other parameters. Among the eight tested samples, three of them show high crystal quality with high intensity (0001) diffraction peak, characteristic of the wurtzite crystalline structure of ZnO, and one of them exhibits piezoelectric coefficient values of ≈11pC N−1. That sample corresponding to a ZnO film deposited at the lowest rg of 0.075 nm s−1, confirmed the key role of the deposition parameters on the piezoelectric response of films, and demonstrated PA‐MS as a promising technique to produce high‐quality piezoelectric thin films.

The temporal profile of self-prioritization

Personal relevance exerts a powerful influence on decisional processing, such that arbitrary stimuli associated with the self are classified more rapidly than identical material linked with other people. Notwithstanding numerous demonstrations of this facilitatory effect, it remains unclear whether self-prioritization is a temporally stable outcome of decision-making. Accordingly, using a shape-label matching task in combination with computational modeling, the current experiment investigated this matter. The results were informative. First, regardless of the target of comparison (i.e., friend or stranger), self-prioritization was a persistent product of decision-making across the testing session. Second, a variant of the standard drift diffusion model in which decisional boundaries collapsed gradually over the course of the task best fit the observed data. Third, whereas the efficiency of stimulus processing increased for other-related stimuli during the task, it decreased for self-related material. Collectively, these findings advance understanding of the temporal profile of self-prioritization.

Impact of organizational structure and in-organization resource allocation on trust and trustworthiness

We experimentally investigated how different organizational structures (horizontal, vertical) and in-organization resource allocation methods (equal, unequal) impact individuals’ trust-related behavior using a two-stage, three-player trust game. As factors influencing trust or trustworthiness, we focused on influential and resource-based power shaped by organizational structures and resource allocation methods, respectively. We expanded the inequity aversion model with power inequities and demonstrated that power inequities can impact individuals’ inequity aversion and therefore their trust-related behavior. In the equal resource allocation treatment, the trustees exhibited a greater probability of being trustworthy, and the trustors were more trusting in the horizontal structure treatment. Those trustees holding both power types significantly encouraged trust and trustworthiness, while influential power was more effective in increasing trustworthiness. This study makes a novel theoretical contribution by exploring the motivation factors of power inequity aversion and explaining how organizational structures and resource allocation methods impact individuals’ trust-related behavior via inequity aversion.

Influence of laser power and scanning speed on microstructure evolutions and mechanical properties of the SLM fabricated Al-Mg-Mn-Sc-Zr alloy

The Al-Mg-Mn-Sc-Zr alloy is fabricated by selective laser melting (SLM). The influence of laser power and scanning speed on microstructure evolutions and mechanical properties is studied in this research. Results indicate that increasing laser power can refine grain structures and reduce anisotropy on the printing surface. However, the increase in laser power will enhance the residual stress inside the alloy, leading to a decrease in elongation. The scanning speed affects the molten pool energy input and cooling rate. When the scanning speed is between 750mm/s-1250mm/s, the alloy achieves a good grain refinement effect and weak texture strength. In addition, there exists a large number of nano-scaled Al3(Sc,Zr) particles precipitated during solidification and the subsequent annealing process, which can significantly enhance yield strength of the alloy. Overall, the Al-Mg-Mn-Sc-Zr alloy has a wide SLM forming window. When the laser power ranges from 200W to 250W, the scanning speed ranges from 750mm/s to 1250mm/s, and the volume energy density ranges from 80J/mm3 to 130J/mm3, the Al-Mg-Mn-Sc-Zr alloy can obtain good formability and mechanical property.

Commercialization of Hip-Hop Culture and the Evolution of Youth Consumption Patterns from Symbols of Rebellion to Fashion Trends

This paper explores the commercialization of hip-hop culture and its profound influence on fashion and youth consumption patterns. Originally a symbol of rebellion and a voice for marginalized communities, hip-hop has evolved into a mainstream cultural force, reshaping global fashion trends. The transition from underground streetwear to luxury fashion is analyzed through key moments in hip-hop’s history, including collaborations with major brands like Adidas, Nike, and Gucci. The rise of streetwear brands such as Supreme, Off-White, and Yeezy exemplifies how hip-hop’s commercial success has transformed it into a powerful influence on youth identity and social status. However, this commercialization presents a double-edged sword, raising concerns about the loss of authenticity and cultural roots. The paper examines how social media and digital platforms have amplified hip-hop’s reach and discusses the ongoing tension between its original rebellious spirit and its role as a commercial enterprise. The study also highlights the global impact of hip-hop on consumption behaviors, focusing on the rise of exclusive product drops and the commodification of streetwear.

Positive Identity Construction in Diverse Organizations

Our desire to cultivate and sustain positive identities has a powerful influence on workplace diversity, equity, and inclusion (DEI) dynamics. While sometimes the quest for positive identities promotes celebration of diversity and uniqueness, in many other circumstances our inherent motivation to strive toward building more positive identities can have unintended consequences for DEI in organizations. In this review, we organize research on positive identities at work to better understand the experiences of the diverse set of individuals that compose our work organizations today. We invite a critical examination of how individuals with underrepresented and dominant identities deal with identity demands in diverse workplaces in both helpful and harmful ways. We conclude with directions for future research on interventions that mitigate identity threat and promote inclusion.

Nickel-decorated ZnO nanoparticles for effective solar reduction of hexavalent chromium and removal of selected pharmaceuticals

The efficient visible light driven photocatalytic reduction of hexavalent chromium, Cr(VI) was demonstrated using ZnO nanoparticles (NPs) decorated with oxo-clusters of transition metals. The ZnO NPs were synthesized by a facile one-pot solvothermal synthesis followed by a fast microwave-assisted (MW) grafting of transition metals on the surface of NPs. Nickel was found to be the most active transition metal for photocatalytic activity as demonstrated by reduction of Cr(VI) to Cr(III). The optimally grafted samples contained 0.5 wt% Ni and increased photocatalytic activity by almost one-fold. The oxo-clusters did not enter the lattice of ZnO but rather resided on the surface and their efficient bonding to the ZnO surface was proved by Raman, TEM and X-Ray absorption techniques. Influence of MW power was studied and shown that excessive power load leads to formation of elongated structures of ZnO which decreases the photocatalytic activity. It was demonstrated by measuring fluorescent radical products that electrons, efficiently transferred via oxygen, were the main active species in combination with the unchanged oxidation power of holes and •OH in the grafted samples. The applicability of the materials was tested in immobilized plug flow photoreactor system degrading five pharmaceuticals simultaneously where their long-term use was shown.

A new method for direct welding of alumina and zirconia ceramics by ultrashort pulse laser for high temperature application

The direct welding of alumina and zirconia ceramics by ultrashort pulse laser is presented for the first time. Compared to traditional dissimilar ceramic joining techniques such as brazing and diffusion welding, this method shows various advantages, including operation at room-temperature, higher welding efficiency, and negligible impact on base materials. The joint microstructure consists of a combination of Al2O3 and ZrO2 phases, without new phases detected. By adjusting the laser focal point position, the phase content within joint is effectively regulated, successfully preventing crack formation in alumina substrate. The influence of laser power and welding speed on joint morphology and mechanical property is fully investigated. The highest four-point bending strength of 365.5MPa and shear strength of 33.4MPa are achieved. After experiencing thermal cycling test at 1000°C, the joint strength and microstructure does not exhibit significant changes, demonstrating the excellent high-temperature durability of the sample.
