Authors: Nagib Riham , Farkas Andrei Zoltan , Szuhanek Camelia 
Published: June 2024

AbstractThe composite attachment loss during orthodontic clear aligner therapy is an adverse event that commonly happens in clinical practice and can affect the overall outcome and length of treatment. The aim of our research is to provide a basis for the further study of an innovative digital protocol and application method for orthodontic aligner attachments. Two 3D models were designed, one based on the proposed protocol and the other on the conventional method for aligner attachment application. Four attachment shapes were used to identify the maximum values for the von Mises equivalent stresses, the maximum displacements values and the areas in which these values were recorded through FEM analysis. The results of the mechanical simulation show lower values of von Mises stress recorded in the 3D printed attachments assemblies, independent of their shape, when simulated under the same boundary and load conditions. The trapezoidal prism shaped 3D printed model has a 3.7 times smaller displacement value (0.088 [mm]) compared to the adhesive resin model (0.326 [mm]). In conclusion, the proposed protocol for aligner attachments and the introduction of innovative materials is a promising method of solving conventional attachment problems in current orthodontic treatments.

Published: June 2024

AbstractA novel context‐based privacy policy deployment model enhanced with bioinspired Q‐learning optimisations is presented. The model addresses the challenge of maintaining privacy while ensuring data integrity and usability in various settings. Leveraging datasets including Adult (Census Income), Yelp, UC Irvine Machine Learning, and Movie Lens, the authors evaluate the model's performance against state‐of‐the‐art techniques, such as GEF AL, Deep Forest, and Robust Continual Learning. The approach employs Firefly Optimiser (FFO) and Ant Lion Optimiser (ALO) algorithms to dynamically adjust privacy parameters and handle large datasets efficiently. Additionally, Q‐learning enables intelligent decision‐making and rapid adaptation to changing data and network conditions and scenarios. Evaluation results demonstrate that the model consistently outperforms reference techniques across multiple metrics, including privacy levels, scalability, fidelity, and sensitivity management. By reducing reputational harm, minimising delays, and enhancing network quality, the model offers robust privacy protection without sacrificing data utility. Overall, a dynamic context‐based privacy policy deployment approach, enhanced with bioinspired Q‐learning optimisations, presents a significant advancement in privacy preservation methods. The combination of ALO, FFO, and Q‐learning techniques offers a practical solution to evolving data privacy challenges and enhances flexibility in various use case scenarios.
Energy injection adaptive technology for wireless power transmission based on parameter identification
Authors: Li Zhe , Li Lijuan 
Published: June 2024

AbstractThis paper presents an innovative adaptive strategy implemented in wireless power transmission (WPT) systems to overcome efficiency challenges due to coupling structure misalignment and load variability. A novel versatile transmitter, capable of alternating between single and dual voltage source states via two MOSFETs has been designed. Initially, the system operates in a single voltage source mode, mutual inductance and load characteristics are pinpointed using a particle swarm optimization algorithm. Subsequently, the system transitions to dual voltage source mode, where it fine‐tunes the auxiliary voltage source's amplitude and phase based on the determined mutual inductance and load values to realize zero phase angle for optimal impedance matching. The experimental results show that this method can obviously improve the output power of WPT system. This method stands out for its simplicity, adaptability and rapid response, suggesting its potential for practical use in dynamic charging applications.
Investigation and implementation of a common ground DC‐DC buck converter with a novel control method for loss reduction in the converter
Authors: Sani Sajad Ghabeli , Banaei Mohamad Reza , Hosseini Seyed Hossein 
Published: June 2024

AbstractThis paper proposes a new control method for loss reduction of two series buck converters. The proposed method can be applied to each series of buck converters with two power switches. To enhance the efficiency of the converter compared to other structures, a method based on determining operating cycles for loss reduction is employed, leading to increased output efficiency of the converter. Additionally, to demonstrate the efficiency improvement using the proposed method compared to the conventional approach, the efficiency of converter is calculated through theoretical computations under real conditions, and the output results are compared for both losses and efficiency. In addition, the proposed high‐buck converter in this paper benefits from a common ground advantage and exhibits a suitable conversion ratio. The high‐buck converters are used in numerous applications for situations with low voltage and low power. The most important applications for these converters are the power supply for mobile phones, tablets, and other portable electronic devices, battery chargers, and LED drivers. Here, in order to demonstrate the validity of the proposed method, the MATLAB‐Simulink results are provided. Moreover, in order to show the feasibility of the high‐buck converter, a 100‐W prototype has been implemented and the experimental results are provided.

Published: June 2024

Abstract
Background Surveillance colonoscopy after polyps have been detected at screening aims to reduce the risk for subsequent colorectal cancer, so-called post-colonoscopy colorectal cancer (PCCRC). Inconsistencies exist as to whether the risk should be stratified by histologic subtype. We aimed to compare the risk for PCCRC mortality in screening participants with sessile serrated lesions (SSLs)/traditional serrated adenomas (TSAs), hyperplastic polyps (HPPs), or conventional adenomas.
Methods Screening colonoscopy registry data were linked to death registry data between 2010 and 2022. We assessed the association of PCCRC death after a diagnosis of SSL/TSA, conventional adenoma, or HPP by Cox regression, and stratified by polyp size ≥10 and <10 mm.
Results 383,801 participants were included in the analysis. There were 1490 HPPs ≥10 mm (2.6%), compared with 1853 SSL/TSAs (19.6%) and 10,960 conventional adenomas (12.9%). When adjusted for polyp location, the association of polyp size ≥10 mm with PCCRC death was of similar magnitude in participants with conventional adenomas (hazard ratio [HR] 3.68, 95%CI 2.49–5.44), SSL/TSAs (HR 2.55, 95%CI 1.13–5.72), and HPPs (HR 5.01, 95%CI 2.45–10.22). Participants with HPPs mostly died of tumors in the distal colon (54.1%; n = 20), while participants with SSL/TSAs more frequently died of proximal tumors (33.3%; n = 3).
Conclusions Across all histologic types, participants with polyps ≥10 mm had at least a two-fold increase in the likelihood of PCCRC death compared with those with polyps <10 mm. These data suggest that size, rather than histologic subtype, should be a determinant for risk stratification after screening colonoscopy.

Published: June 2024

AbstractMitochondria are important organelles in cells for energy production, and mitochondrial damage caused by various reasons is an important factor promoting disease progression. Mitochondrial damage involves structural damage and mitochondrial DNA damage, which are closely related to the occurrence and development of respiratory system diseases. In recent years, a large number of studies have confirmed the significant role of mitochondrial damage in the progression of respiratory system diseases, which may be an important target for the treatment of respiratory system diseases with traditional Chinese medicine (TCM). This article reviews the role of TCM in regulating mitochondrial damage for intervention in respiratory system diseases such as chronic obstructive pulmonary disease, lung cancer, pulmonary fibrosis, acute lung injury, asthma, and pneumonia, aiming to provide a basis for the study of the pathogenesis and drug action targets of respiratory system diseases.

Published: June 2024

AbstractEndoscopic sclerotherapy is the first-line modality to manage gastric variceal bleeding; however, knowledge of other treatment options is also essential, especially in case of failure of the endoscopic approach. We are reporting a rare case of successful rescue gastric varices embolization through the transsplenic route in a gastric varices bleeding patient who presented with massive hematemesis and blood from the ileostomy drain site secondary to complete splanchnic portal venous system thrombosis when all other treatment options were not feasible or unsafe. Proper cross-sectional imaging evaluation, knowledge of treatment options, and understanding of intraprocedural challenges are essential for managing gastric varices.
Endoscopic Ablation of Perihilar Biliary Malignancies
Authors: Buerlein Ross C. D. , Kundra Arjun , Wang Andrew Y. 
Published: June 2024

AbstractCholangiocarcinoma (CCA) is a malignancy arising from biliary epithelial cells and is subdivided based on the location within the biliary tree. The treatment of CCA differs based on the anatomical involvement within the biliary tree. Perihilar CCA (pCCA) arises between the cystic duct and the secondary branches of the right and left hepatic ducts. Surgical resection and liver transplantation offer the only hope for cure in pCCA, but, unfortunately, more than 80% of patients are considered surgically unresectable at the time of diagnosis resulting in a limited overall life expectancy of less than 1 year. For patients with surgically unresectable pCCA, treatment options are limited and include chemotherapy/chemoradiotherapy and biliary drainage via endoscopic stenting or percutaneous drainage with minimal overall survival benefits. However, endobiliary ablation options like photodynamic therapy (PDT), radiofrequency ablation (RFA), and, to a lesser degree, intraluminal brachytherapy have shown improvements in overall survival and improvements in stent patency and now should be considered for all cases of surgically unresectable pCCA. In fact, the 2023 American College of Gastroenterology (ACG) Clinical Guidelines on the diagnosis and management of biliary strictures recommend endobiliary ablation (PDT or RFA) for patients with surgically unresectable pCCA rather than stenting alone.
A league made in the economy’s image: destabilised stability and the English Premier League’s Minsky moment
Authors: Jackson James , Silverwood James 
Published: June 2024

AbstractThe English Premier League (EPL) has drawn the attention of scholars from a variety of disciplinary backgrounds in recent years, yet its underlying economic model and the politics underpinning it remain underexplored within the literature. To address this gap, we situate the EPL within Minsky’s Financial Instability Hypothesis (FIH) to examine the unstable financial foundations upon which the sporting enterprise is built. As such, we contend that the EPL can be understood as a reflection of the broader pathology of British politics since the 1980s. By placing the EPL within the Minsky cycle, we demonstrate how the actors that make up the league skirt the boundaries of hedge, speculative and Ponzi financiers, as the over-leveraging of clubs becomes ever more contingent upon debt-based instruments and loss-leading broadcasters to preserve the league’s economic status. Contrary to the tendency to abstract the role of fans from the economics of football, we conclude that what prevents the league from reaching its own collapse in asset values—known as a Minsky moment—is them providing the ‘effective demand’ for football.
Audit report lag and key audit matters in Australia
Authors: Rahaman Md. Mustafizur , Bhuiyan Md. Borhan Uddin 
Published: June 2024

AbstractWe aim to investigate the impact of mandatory key audit matters (KAMs) disclosure on audit report lag (ARL). Additionally, we examine the potential moderating effect of firm size on the association between KAMs and ARL. We conduct Ordinary Least Square regression analyses using a sample of 602 firm-year observations from 2018 to 2020. Our findings indicate that the disclosure of KAMs is associated with a reduction in firm ARL. Furthermore, we find that the association between KAMs and ARL is particularly pronounced in large firms, suggesting that the impact of KAMs disclosure on ARL is more significant in this context. Additionally, our research reveals that the negative association between KAMs disclosure and ARL becomes more prominent when the education level of the audit committee chair is higher. Our findings underscore the importance of transparent reporting through KAMs disclosure and the role of knowledgeable and educated individuals in audit committees in facilitating a more efficient and timely audit process. Also, our finding indicates that the beneficial effect of KAMs may be more noticeable to larger firms.
Colonial policy, ecological transformations, and agricultural “improvement”: comparing agricultural yields and expansion in the Spanish and U.S. Philippines, 1870–1925 CE

Published: June 2024

AbstractBurgeoning global trade and colonial policies promoted transformations in land use and agriculture throughout tropical regions in the 19thand 20thcenturies, but the local and regional ecological consequences of landscape changes are still being identified and analysed. The Philippine Archipelago, which experienced successive colonial regimes across more than 7100 islands, exemplifies the multiplicity of ecological outcomes produced by these transformations. To better characterise diverse landscape change, we use colonial censuses and datasets to assess land use, production and agricultural yields in the Philippines during the late Spanish and early U.S. colonial periods (ca. 1870–1925). Our novel digital, quantitative analysis indicates that, at the national and provincial scales, agricultural production and land use increased for all major crops in both periods, while agricultural yields were mostly constant. Our results suggest that colonial investments to “improve” Philippine agriculture, specifically their efforts to increase production per hectare, were not effective. Our provincial-scale analysis also confirms the importance of distinct labour patterns, geographies and socio-political arrangements in defining this period’s ecological consequences, and we provide quantified and historically contextualised data in a format amenable to ecologists to promote future, localised historic ecological research.
Echoes of the gothic: transmedia reinterpretations of Edgar Allan Poe’s legacy in independent films and video games
Authors: Torres-Toukoumidis Angel , León-Alberca Tatiana , Henriquez-Mendoza Eduardo 
Published: June 2024

AbstractThis study critically examines the development of audiovisual and interactive content that draws on Edgar Allan Poe’s oeuvre, with a particular focus on the interplay of transmedia storytelling and gothic elements within these narratives. Utilizing summative content analysis and non-participant observation, this research investigates five films and five independent video games that reinterpret Poe’s literary themes. The results underscore the necessity of incorporating Mythos, Topos, and Ethos in adaptations to faithfully evoke the profound emotional resonance and explore the psychological and existential dilemmas inherent in Poe’s works. Our analysis reveals distinct narrative strategies in cinema and video games: while horror predominates in film, integrating supernatural elements to evoke fear, video games predominantly leverage noir, crafting complex crime narratives infused with cynicism and dark ambiance. Additionally, the study highlights how gothic elements of abjection and sublimity are leveraged to navigate themes of mortality, morality, and the uncanny, thereby ensuring the continued relevance of Poe’s legacy in contemporary media landscapes. This adaptation process not only preserves the essence of Poe’s narrative but also dynamically engages a modern audience through innovative transmedia platforms, illustrating the enduring impact of his work on popular culture.

Published: June 2024

Abstract
We explore the stability of floating objects at a two-fluid interface through mathematical modeling and experimentation. Our models are based on standard ideas of center of gravity, center of buoyancy, and Archimedes’ Principle extended to the two-fluid scenario. We investigate floating shapes with uniform, two-dimensional cross sections and identify analytically and/or computationally a potential energy landscape that helps identify stable and unstable floating orientations. We compare our analyses and computations to experiments on floating objects designed and created through 3D printing. Additionally, the paper includes open problems for further study.
Magnetic vortex polarity reversal induced gyrotropic motion spectrum splitting in a ferromagnetic disk
Authors: Cui Xiaomin , Hu Shaojie , Hidaka Yohei , Yakata Satoshi , Kimura Takashi 
Published: June 2024

Abstract
We investigate the gyrotropic motion of the magnetic vortex core in a chain of a few micron-sized Permalloy disks by electrical resistance measurement with amplitude-modulated magnetic field. We observe a distinctive splitting of the resistance peak due to the resonant vortex-core motion under heightened radio frequency (RF) magnetic field excitation. Our micromagnetic simulation identifies the splitting of the resonant peak as an outcome of vortex polarity reversal under substantial RF amplitudes. This study enhances our understanding of nonlinear magnetic vortex dynamics amidst large RF amplitudes and proposes a potential pathway for spintronic neural computing thanks to their unique and controllable magnetization dynamics.
Nonlocal structural effects of water on DNA homology recognition
Authors: Haimov Ehud , Hedley Jonathan G , Kornyshev Alexei A 
Published: June 2024

Abstract
The mechanism behind mutual recognition of homologous DNA sequences prior to genetic recombination is one of the remaining puzzles in molecular biology. Leading models of homology recognition, based on classical electrostatics, neglect the short-range nonlocal screening effects arising from structured water around DNA, and hence may only provide insight for relatively large separations between interacting DNAs. We elucidate the role of the effects of the nonlocal dielectric response of water on DNA–DNA interaction and show that these can dramatically enhance the driving force for recognition.
Whale sound signal denoising based on SVMD and improved wavelet thresholding

Published: June 2024

Abstract
Cetaceans have formed a set of sonar systems that rely on acoustic waves for communication, positioning, and environmental recognition in their long-term evolution. This sonar system is characterized by strong anti-interference ability, high localization accuracy, and strong recognition ability. Effective denoising of cetacean sound is the first link in the process of applying cetacean signal analysis. For the problem of effective denoising of whale sound signals in complex underwater environments, a new denoising method based on successive variational mode decomposition (SVMD) and improved wavelet thresholding is proposed. Firstly, the noisy high-frequency intrinsic mode functions (IMFs) obtained by SVMD decomposition are sieved by the correlation coefficient method; then, these high-frequency components are subjected to improved wavelet thresholding for noise reduction; finally, the signal is reconstructed with the low-frequency IMFs. The simulation results show that the denoising method works well, and the signal-to-noise ratio is high and the root-mean-square error is low, which effectively preserves the important information of the original signal.
Few-shot learning fault diagnosis of rolling bearings based on siamese network

Published: June 2024

Abstract
This paper focuses on the fault diagnosis problem in the scenario of scarce bearing samples, facing two main challenges: complex noise background and variations in operating conditions. While deep learning-based fault diagnosis methods have achieved significant progress, they heavily rely on large amounts of samples. This paper proposes a few-shot learning fault diagnosis method based on siamese networks (SN), which classify samples based on the similarity between pairs rather than end-to-end classification. Tested on two bearing datasets, the proposed method outperforms SVM, DCNN, WDCNN, and CNN-BiGRU. The influence of factors such as parameter regularization, noise, and load variation on the proposed method is also discussed. Experimental results demonstrate that double parameter regularization contributes more to the model’s generalization ability, maintaining good stability and generalization even under noise interference or load variation.
