Considering the Assumptions of the Technocentric Model of Democratic Flourishing and Decay
Authors: Livingston Steven , Miller Michael 
Published: January 2025

A common explanation of democratic backsliding relies on methods and models adopted from social psychology and cognitive science. According to this model, individuals are radicalized by algorithmically amplified social media content that exacerbates cognitive bias. Following a critical evaluation of this model, we present an alternative organizational-level explanatory framework, one that considers the effects of civil society organizations on political parties, especially conservative parties. In some of the literature, civil society organizations are regarded as a potential threat to the stability of liberal democracy. Bennett and Segerberg’s connective action model suggest that under certain conditions routinized online communication—such as hashtags, subreddits, and Facebook groups—constitute an organization. This is communication as organization. If conventional party-aligned surrogate organizations threaten the cohesion and stability of democracy, then digitally constituted organizations like #QAnon or #StoptheSteal are even more corrosive to party ideological boundaries and democratic stability. This article is adapted from the concluding chapter of our forthcoming work, Connective Action and the Rise of the Far-Right: Platforms, Politics, and the Crisis of Democracy.

Abstract: Orthogonal Time Frequency Space (OTFS) modulation has been verified in high-mobility scenarios as an effective solution to address the Doppler shift effect. To further improve the data transmission efficiency of the system, this paper delves into different channel coding techniques in the Delay-Doppler (DD) domain under OTFS modulation. This paper evaluates the system performance of various encoding schemes under multiple user mobility rates, including Convolutional codes, Turbo codes, Low-Density Parity-Check (LDPC) codes, and Polar codes. Additionally, this paper investigates the impact of adopting different modulation constellation mapping schemes on the system’s Bit Error Rate (BER) and explores strategies for enhancing system performance in high-speed data transmission scenarios. The simulation results show that the code-based system reduces the BER by about 17–35% compared to the uncoded OTFS system. In this case, the LDPC code system has a 10 dB Signal-to-Noise Ratio (SNR) gain. The simulation results demonstrate that combining coding techniques with OTFS modulation can significantly enhance the performance of communication systems in highly dynamic environments, with LDPC and Turbo codes showing notable advantages in performance improvement. The findings of this paper not only highlight the importance of choosing the right coding scheme and provide valuable references for the design of high-speed mobile communication systems in the DD domain.

Published: January 2025

This paper addresses the problem of the prediction of zombie companies. Despite their relevance, financial issues represent an area scarcely considered in relation to the tourism industry and this topic has so far remained totally unexplored. Zombie firms cause great damage to the sector in which they compete. However, there is no consensus regarding what actions should be applied to them are not due to the negative consequences of maintaining or liquidating them. In view of this, the key issue is to prevent them from entering this state. It would therefore be useful to have a methodology for predicting years in advance when a company will become a zombie firm. For this purpose, this article has used different artificial intelligence algorithms applied to easily obtained accountant data. Thus, 78.4% of correct predictions have been utilizing a dataset of 356 Spanish small and medium-sized enterprises in the tourism sector.

Published: January 2025

Introduction:
Total knee arthroplasty (TKA) is one of the most commonly performed orthopaedic surgeries in the United States, yet little information exists regarding its utilization in different settlement types. This study aimed to determine the number of TKA-performing surgeons by settlement type and assess trends in the volume of TKAs in urban, micropolitan, small town, and rural settings.

Methods:
Using the Medicare Provider Utilization and Payment Data: Physician and Other Practitioners database, the number of orthopaedic surgeons performing primary and revision TKAs from 2013 to 2020 was determined. The zip code where TKA was performed was used to identify the rural-urban commuting area codes (RUCA) and classify locations into one of four settlement types: urban/metropolitan, micropolitan (large town), small town, or rural. Correlations in surgeon number and TKA volume by settlement type were evaluated by Mann-Kendall tests.

Results:
Between the years of 2013 and 2020, TKAs were billed by up to 7,192 orthopaedic surgeons. The proportions of TKAs occurring in settlement types were the following: urban/metropolitan, 85.2%; micropolitan, 11.5%; small town, 2.6%; rural, 0.6%. Areas without RUCA data had 32.9 TKAs per surgeon per year, the highest overall median surgeries per year over the 8-year period. The median number of TKAs per surgeon per year was 28, 25.4, 21.4, and 20.7 for urban/metropolitan, micropolitan, small towns, and rural areas, respectively.

Conclusion:
A considerable difference exists in both the number of surgeons and the proportion of TKAs conducted across various settlement types. Twenty percent of population in the United States lives in rural areas; however, only 0.6% of billed TKAs occurred in these areas over the study period, indicating a gap in orthopaedic care access. It is imperative to understand TKA surgeon distribution and focus on strategies aimed at attracting and retaining proficient surgeons to address the healthcare needs of these underserved regions.

Securing Machine Learning Models: Homomorphic Encryption and its impact on Classifiers
Authors: Adamsetty Rishitha , Cherukuri Aswani Kumar , Jonnalagadda Annapurna 
Published: January 2025

Homomorphic encryption (HME) enables encrypted computations and provides secure data analysis while addressing key concerns around data privacy and regulatory compliance. It has significant implications for machine learning (ML) models, particularly in enhancing the privacy, security, and usability of ML models. Training ML models on homomorphically encrypted data is a growing area of research. While HME offers several security-related benefits to ML models, there are concerns about the ML models performance, when applied over homomorphically encrypted data. Research efforts are needed to analyse the potential impact of HME on the performance of ML models. This paper deals with our work in this direction, presenting the analysis of various ML classifiers on homomorphically encrypted data. We discuss the performance of classifiers such as logisticregression, Support Vector Machines, Neural networks and Decision trees on data encrypted using HME. We follow a systematic approach to analyse the performance in terms of accuracy and efficiency. Our results indicate that the performance of classifiers is nearly identical to the results obtained when they applied on unencrypted data.

(1) Background: In recent years, there have been many technological advances in intraoral scanners. These developments have improved the efficiency and accuracy of intraoral scanning in CAD/CAM procedures. (2) Aim: The study aimed to compare results obtained in dental impression technology with intraoral scaner to impressions taken with conventional impression materials. (3) Methods: the stages of two types of clinical oral rehabilitation (in dentate and edentulous patients) were compared. In each clinical situation, both impressions were taken using the classic impression method and digital impressions by intraoral scanning, one involving fixed prosthetics and the other removable prosthetics. (4) Results: During and after taking intraoral impressions using both the classic and digital methods via intraoral scanning, the digital impression produced a more positive perception than the classic impression. The time needed to perform an impression was statistically significantly shorter for digital one in dentate patients but longer in edentulous patients. (5) Conclusions: Intraoral digital impression techniques offer significant advantages over conventional methods that use impression material to increase patient comfort and improve communication between patients, dental technicians, and clinicians. These advantages are essential for dentate patients.

Published: January 2025

Коррозия процестерін зерттеу және металдарды коррозиядан қорғау әдістері мен қабаттарын жасау қазіргі ғылыми-техникалық мәселелердің өзектілігіне жатады. Металлды коррозиядан қорғаудың кең тараған түрі- өндірістік жағдайларда агрессивті ортамен жанасатын металлдар мен қорытпалардың коррозия жылдамдығын төмендетуге мүмкіндік беретін ингибиторларды қолдану болып табылады. Қазіргі уақытта экологиялық таза технологияларды пайдалана отырып, металдар мен қорытпаларды қорғауға арналған , жануарлар шикізаты негізіндегі қол жетімді, улы емес және арзан коррозия ингибиторларын жасау «табиғи» химия саласындағы жетекші тенденциялардың бірі болып табылады.
Бұл жұмыста 1,0 моль/л агрессивті ортада СТ3 көміртекті болатқа жануар майының коррозияға қарсы тиімділігі гравиметриялық әдіспен зерттелді. Агрессивті орта ретінде түзды және қышқылды ерітінділер алынған. Ингибитордың тиімділігі қалыпты стандартты орта жағдайында 0,5-2,0 г/л мөлшерінде зерттелген. Болат пластиналарының әртүрлі агерссивті ортада масасының жоғалуын негізге алып, жалпы 1 жылда кететін массалық шығынды есептей отырып, жануар майы қосылған ерітіндінің болат пластинасының коррозияға қарсы көрсеткішінің проценттік тиімділігі анықталды. Жоғары тиімділікке болат пластина бетіндегі ингибитордың өздігінен физиосорбциялануы есебінен қол жеткізілетіндігі анықталды. Нәтижесінде жануар майы болат пластиналарының бетінде жылтыр қорғаныс қабатын түзіп, оның массасының жоғалуына кедергі келтіретіндігі айқындалды. Сонымен қатар ингибитор концентрациясының жоғарылауы коррозияға қарсы тиімділіктің артуын көрсетті.
