However, integrating RESs-such as wind turbines and photovoltaic systems-into the utility grid introduces significant technical challenges. These challenges stem from the nonlinear characteristics, intermittent nature, and inherent uncertainties of RESs. High penetration levels of RESs exacerbate issues such as inadequate generation reserves, elevated fault currents, increased system uncertainties, and degraded power quality. The unpredictable and energy-dilute nature of wind and solar resources further complicates grid stability and control. To address these challenges, this paper proposes a hybrid RES architecture integrated with the grid, enhanced by advanced control strategies to improve system performance. The proposed framework incorporates cutting-edge technologies, including Flexible AC Transmission Systems (FACTS), fault current limiters, and energy storage systems, to mitigate technical barriers and ensure stable grid operation. The system design and performance evaluation are conducted through comprehensive software simulations using Python and Power System Simulation for Engineering (PSSE). Simulation results demonstrate the effectiveness of the proposed approach in enhancing grid stability, power quality, and fault resilience under high-RES penetration scenarios. The proposed strategy reduces THD to 1.8% (vs. 3.1% for conventional PI control), limits voltage fluctuations to ± 2.1%, and maintains frequency deviations within ± 0.1 Hz-outperforming both IEEE 519 and EN 50,160 standards. Comparative analysis shows 40% faster settling times than MPC-based approaches. This study provides a robust solution for the seamless integration of RESs into modern power systems, paving the way for a sustainable energy future.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"23445"},"PeriodicalIF":3.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144554414","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, Zheng et al. proposed an efficient and privacy-protecting certificateless aggregate signature scheme, which is applicable to VANETs. However, through in-depth analysis, we found that it is vulnerable to temporary rogue key attacks. That is, an adversary can exploit the random numbers in signatures to generate an ephemeral rogue key, enabling him/her to forge an aggregate signature using both this rogue key and his/her private key. Furthermore, the forged signature can pass the verification without being detected. This paper fixes this vulnerability and proposes a security-enhanced CLAS scheme for VANETs. Specifically, our improved solution incorporates an additional aggregator's signature into the original framework and implements simultaneous verification of both the aggregator's signature and the aggregate signature to effectively resist rogue key attacks. In terms of security, we conducted a rigorous analysis of the security-enhanced CLAS scheme. In addition, through performance evaluation experiments, we compare the computational complexity and communication overhead of the security-enhanced CLAS scheme and some other schemes. The experimental results show that the security-enhanced CLAS scheme demonstrates significant advantages in both computational efficiency and communication cost while maintaining security. Our method can provide valuable references for the design of security solutions in related fields.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"23663"},"PeriodicalIF":3.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144554417","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Multivariable logistic regression models were fit with the dependant variable being hip or any fragility fracture and the independent variable being the binary regional body composition groups. All results were adjusted for FRAX clinical factors where we found that the lowest tertile of abdominal fat was associated with reduced odds of any fracture (OR 0.78, 95% CI 0.74-0.82), while the highest tertile was linked to increased odds (OR 1.22, 95% CI 1.17-1.29) but was not associated with hip fracture. For left hip fat, the lowest tertile was linked to decreased odds of any fracture (OR 0.61, 95% CI 0.58-0.64), and the highest tertile showed increased odds of any fracture (OR 1.57, 95% CI 1.50-1.65) and hip fracture (OR 1.32, 95% CI 1.07-1.63).

By integrating this method with laboratory tests, a finite element numerical calculation model incorporating cohesive elements is established. The reliability of the cohesive force model is validated through comparisons of the load-displacement curves, bending moments, and crack distribution patterns. Building on this foundation, a numerical calculation model for cantilever anti-slip piles subjected to acid rain corrosion, considering various corrosion rates, is developed. This model is employed to analyze the bearing characteristics of anti-slip piles under different corrosion conditions. Additionally, stiffness and bearing capacity calculation formulas for corroded reinforced anti-slip piles are proposed and verified using existing experimental data.The results indicate that, compared to the embedded model, the cohesive model exhibits load-displacement curves and crack distribution patterns that more closely align with experimental data, demonstrating a higher degree of correlation. As the corrosion rate increases, the peak stress at the bond interface of reinforced concrete decreases, the maximum displacement increases, and the strain ratio between reinforcement and concrete rises, ultimately leading to a reduction in bearing capacity. Among the factors influencing the bearing performance of acid rain-resistant piles, the strength of the reinforcement is the most significant, followed by bond strength, with the strength of concrete being the least influential. When the corrosion rate is low, the calculated values for the stiffness and bearing capacity of corroded reinforced anti-slip piles are in good agreement with experimental values.These research findings provide a valuable scientific basis and practical significance for evaluating the bearing characteristics of cantilever anti-slip piles in environments affected by acid rain corrosion.</p>","PeriodicalId":21811,"journal":{"name":"Scientific Reports","volume":"15 1","pages":"23371"},"PeriodicalIF":3.8,"publicationDate":"2025-07-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144554463","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"综合性期刊","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
