The advent of 5G technology aims to revolutionize wireless communication by providing significantly higher data rates, ultra- reliable low latency, and enhanced connectivity. However, optimizing 5G network performance remains a challenging task, particularly in terms of Bit Error Rate (BER) and spectral efficiency. Multiple-Input Multiple-Output (MIMO) technology, coupled with beamforming algorithms, offers a promising solution to these challenges. This study investigates the application of the Fractional Least Mean Square (FLMS) algorithm for beamforming in MIMO systems to improve BER and spectral efficiency in 5G networks. The primary problem addressed is the need for effective interference mitigation and signal enhancement in densely populated environments, which traditional methods struggle to handle. The proposed method utilizes the FLMS algorithm to dynamically adjust the beamforming weights, thereby optimizing the signal reception quality. The algorithm's fractional nature allows for finer adjustments and better adaptation to varying channel conditions compared to conventional LMS algorithms. Simulation results show the efficacy of the proposed method. Specifically, the implementation of the FLMS algorithm in a 4x4 MIMO system shows a reduction in BER by 30% and an improvement in spectral efficiency by 25% compared to traditional beamforming techniques. These numerical values highlight the potential of FLMS in enhancing 5G network performance, making it a viable approach for future wireless communication systems.

Communication systems face challenges from high-power adjacent channel signals, or blockers, inducing nonlinear behavior in RF front ends. Ensuring robust performance in the presence of blockers is crucial for IoT and other spectrum-consuming devices coexisting with advanced transceivers. This paper proposes a flexible, data-driven solution using a Deep Belief Network (DBN) to mitigate third-order intermodulation distortion (IMD) during demodulation. Numerical evaluations of AI-enhanced receivers employing DBN as an IMD canceler and demodulator show significant improvements in bit error rate (BER) performance. The effectiveness of DBN varies with RF front end characteristics, notably the third-order intercept point (IP3).

Wireless Sensor Networks (WSNs) play a crucial role in monitoring and gathering data from remote environments. Maximizing network lifetime is paramount due to constrained sensor node energy. This study addresses the challenge of efficient cluster head selection to prolong network operation. The problem focuses on utilizing the Harris Hawk Optimization (HHO) algorithm for selecting optimal cluster heads in WSNs. HHO mimics the hunting behavior of Harris hawks to iteratively refine the selection process, aiming to minimize energy consumption while maintaining network coverage. The method involves initializing Harris hawks (representing potential cluster heads) within the sensor field, where their movements simulate search and convergence towards optimal locations. Through computational simulations, the effectiveness of HHO is evaluated against traditional methods like LEACH and PSO. Results indicate that HHO outperforms competitors by extending network lifetime up to 30%, with an average reduction in energy consumption by 15%. Specifically, numerical values show an increase in network lifetime from 3000 hours to 3900 hours, while reducing energy consumption from 2000 J/bit to 1700 J/bit. This research underscores the efficacy of HHO in enhancing WSN efficiency through optimized cluster head selection, promising sustainable operation in resource-constrained environments.

Authors:   Hindusthan College of Engineering and Technology, India, Kumar G. Rajiv Suresh , Geetha G. Arul ,   Bishop Appasamy College of Arts and Science, India
Published: October 2024

his research work introduces an Ensemble Adaptive Reinforcement Learning (EARL) approach for efficient load balancing in Mobile Ad Hoc Networks (MANETs). Traditional methods often fail to adapt to the dynamic nature of MANETs, leading to congestion and inefficiency. EARL leverages multiple reinforcement learning agents, trained with Q-learning and Deep Q-Networks (DQN), to optimize routing decisions based on real-time network conditions. The ensemble mechanism combines the strengths of individual agents, enhancing adaptability and performance. Simulation results demonstrate that EARL significantly outperforms traditional methods like AODV and DSR, achieving higher packet delivery ratios, lower end-to-end delays, increased throughput, better energy efficiency, and reduced packet loss, thereby proving its effectiveness in dynamic network environments.

In the era of big data, ensuring privacy while processing vast amounts of sensitive information poses a significant challenge. Traditional encryption methods often fall short in maintaining both privacy and data utility during computation. This paper introduces Two-Trapdoor Homomorphic Encryption (TTHE), a novel approach designed to enhance privacy-preserving capabilities in big data and information security. TTHE combines the strengths of trapdoor functions with homomorphic encryption to enable secure data processing without compromising privacy. With the exponential growth of data, safeguarding sensitive information has become a critical concern. Existing encryption schemes often struggle to balance between privacy preservation and computational efficiency. Homomorphic encryption offers a potential solution by allowing computations on encrypted data, but current methods are limited by performance and scalability issues. The key challenge addressed is the inefficiency and performance bottlenecks in current homomorphic encryption schemes, which hinder their practical application in big data environments. Traditional methods often face limitations in processing large datasets efficiently while maintaining robust security. TTHE is proposed as an enhancement over traditional homomorphic encryption. It integrates two distinct trapdoor functions to provide a dual-layer security approach, enabling efficient and scalable computation on encrypted data. The method involves a novel encryption scheme where operations on ciphertexts are performed without decryption, preserving data privacy throughout the process. Extensive experiments demonstrate that TTHE significantly improves both computational efficiency and security. The proposed method achieved a processing speed increase of 45% compared to conventional homomorphic encryption schemes. Additionally, TTHE maintained a privacy level with a security strength of 128-bit encryption, providing robust protection against potential attacks.

Authors: Li Mengdan , Yu Zhifu , Li Hui , Cao Li , Yu Huihui , Deng Ning , Liu Yunyong
Published: October 2024

Background

Patients with breast cancer endure high levels of psychological and physical pain. Virtual reality (VR) may be an acceptable, safe intervention to alleviate the negative emotions and pain of patients with cancer.

Objective

We aimed to test the long-term effects of VR on psychological distress and quality of life (QOL) with traditional care in Chinese patients with breast cancer. We also explored the intervention mechanism and the acceptability of VR.

Methods

A total of 327 eligible participants were randomly assigned to a VR intervention group or a control group. The Distress Thermometer, QLQ-C30 (Quality of Life Questionnaire version 3.0), and Virtual Reality Symptom Questionnaire were assessed at baseline, postintervention (3 mo), and follow-up (6 mo). Analysis followed the intention-to-treat (ITT) principle. The generalized estimating equations model was used to analyze the longitudinal data, and the PROCESS macro was used to analyze the mediating effect.

Results

Compared with the control group, patients with breast cancer in the VR group had lower distress scores (P=.007), and higher health-related QOL scores (physical, role, emotional, cognitive, and social functioning) after 6 months (P<.05). Psychological distress had mediating effects on the longitudinal association between VR and the health-related QOL (indirect effect=4.572‐6.672, all P<.05).

Conclusions

VR intervention technology may help reduce distress and improve QOL for patients with breast cancer over time. By incorporating a mediating analysis, we showed that the QOL benefits of VR intervention was manifested through positive effects on psychological distress risk factors.

Published: October 2024

Background

Older adults with multiple chronic conditions (MCC) and polypharmacy often face challenges with medication adherence. Nonadherence can lead to suboptimal treatment outcomes, adverse drug events, and poor quality of life.

Objective

To facilitate medication adherence among older adults with MCC and polypharmacy in primary care, we are adapting a technology-enabled intervention previously implemented in a specialty clinic. The objective of this study was to obtain multilevel feedback to inform the adaptation of the proposed intervention (Phenotyping Adherence Through Technology-Enabled Reports and Navigation [PATTERN]).

Methods

We conducted a formative qualitative study among patients, clinicians, and clinic administrators affiliated with a large academic health center in Chicago, Illinois. Patient eligibility included being aged 65 years or older, living with MCC, and contending with polypharmacy. Eligibility criteria for clinicians and administrators included being employed by any primary care clinic affiliated with the participating health center. Individual semistructured interviews were conducted remotely by a trained member of the study team using interview guides informed by the Exploration, Preparation, Implementation, and Sustainment Framework. Thematic analysis of interview audio recordings drew from the Rapid Identification of Themes from Audio Recordings procedures.

Results

In total, we conducted 25 interviews, including 12 with clinicians and administrators, and 13 with patients. Thematic analysis revealed participants largely found the idea of technology-based medication adherence monitoring to be acceptable and appropriate for the target population in primary care, although several concerns were raised; we discuss these in detail.

Conclusions

Our medication adherence monitoring intervention, adapted from specialty care, will be implemented in primary care. Formative interviews, informed by the Exploration, Preparation, Implementation, and Sustainment Framework and conducted among patients, clinicians, and administrators, have identified intervention adaptation needs. Results from this study could inform other interventions using the patient portal with older adults.
Personalized and Culturally Tailored Features of Mobile Apps for Gestational Diabetes Mellitus and Their Impact on Patient Self-Management: Scoping Review
Authors: Jones Catherine , Cui Yi , Jeminiwa Ruth , Bajracharya Elina , Chang Katie , Ma Tony
Published: October 2024

Background

Gestational diabetes mellitus (GDM) is an increasingly common high-risk pregnancy condition requiring intensive daily self-management, placing the burden of care directly on the patient. Understanding personal and cultural differences among patients is critical for delivering optimal support for GDM self-management, particularly in high-risk populations. Although mobile apps for GDM self-management are being used, limited research has been done on the personalized and culturally tailored features of these apps and their impact on patient self-management.

Objective

This scoping review aims to explore the extent to which published studies report the integration and effectiveness of personalized and culturally tailored features in GDM mobile apps for patient self-management support.

Methods

We examined English-language peer-reviewed articles published between October 2016 and May 2023 from PubMed, CINAHL, PsycINFO, ClinicalTrials.gov, Proquest Research Library, and Google Scholar using search terms related to digital tools, diabetes, pregnancy, and cultural tailoring. We reviewed eligible articles and extracted data using the Arskey and O’Malley methodological framework.

Results

Our search yielded a total of 1772 articles after the removal of duplicates and 158 articles for full-text review. A total of 21 articles that researched 15 GDM mobile apps were selected for data extraction. Our results demonstrated the stark contrast between the number of GDM mobile apps with personalized features for the individual user (all 15 mobile apps) and those culturally tailored for a specific population (only 3 of the 15 mobile apps). Our findings showed that GDM mobile apps with personalized and culturally tailored features were perceived to be useful to patients and had the potential to improve patients’ adherence to glycemic control and nutrition plans.

Conclusions

There is a strong need for increased research and development to foster the implementation of personalized and culturally tailored features in GDM mobile apps for self-management that cater to patients from diverse backgrounds and ethnicities. Personalized and culturally tailored features have the potential to serve the unique needs of patients more efficiently and effectively than generic features alone; however, the impacts of such features still need to be adequately studied. Recommendations for future research include examining the cultural needs of different ethnicities within the increasingly diverse US population in the context of GDM self-management, conducting participatory-based research with these groups, and designing human-centered mobile health solutions for both patients and providers.
Use of Artificial Intelligence in Cobb Angle Measurement for Scoliosis: Retrospective Reliability and Accuracy Study of a Mobile App (Preprint)
Authors: Li Haodong , Qian Chuang , Yan Weili , Fu Dong , Zheng Yiming , Zhang Zhiqiang , Meng Junrong , Wang Dahui
Published: October 2024

BACKGROUND

Scoliosis is a spinal deformity in which one or more spinal segments bend to the side or show vertebral rotation. Some artificial intelligence (AI) apps have already been developed for measuring the Cobb angle in patients with scoliosis. These apps still require doctors to perform certain measurements, which can lead to interobserver variability. The AI app (cobbAngle pro) in this study will eliminate the need for doctor measurements, achieving complete automation.

OBJECTIVE

We aimed to evaluate the reliability and accuracy of our new AI app that is based on deep learning to automatically measure the Cobb angle in patients with scoliosis.

METHODS

A retrospective analysis was conducted on the clinical data of children with scoliosis who were treated at the Pediatric Orthopedics Department of the Children’s Hospital affiliated with Fudan University from July 2019 to July 2022. Three measurers used the Picture Archiving and Communication System (PACS) to measure the coronal main curve Cobb angle in 802 full-length anteroposterior and lateral spine X-rays of 601 children with scoliosis, and recorded the results of each measurement. After an interval of 2 weeks, the mobile AI app was used to remeasure the Cobb angle once. The Cobb angle measurements from the PACS were used as the reference standard, and the accuracy of the Cobb angle measurements by the app was analyzed through the Bland-Altman test. The intraclass correlation coefficient (ICC) was used to compare the repeatability within measurers and the consistency between measurers.

RESULTS

Among 601 children with scoliosis, 89 were male and 512 were female (age range: 10-17 years), and 802 full-length spinal X-rays were analyzed. Two functionalities of the app (photography and photo upload) were compared with the PACS for measuring the Cobb angle. The consistency was found to be excellent. The average absolute errors of the Cobb angle measured by the photography and upload methods were 2.00 and 2.08, respectively. Using a clinical allowance maximum error of 5°, the 95% limits of agreement (LoAs) for Cobb angle measurements by the photography and upload methods were –4.7° to 4.9° and –4.9° to 4.9°, respectively. For the photography and upload methods, the 95% LoAs for measuring Cobb angles were –4.3° to 4.6° and –4.4° to 4.7°, respectively, in mild scoliosis patients; –4.9° to 5.2° and –5.1° to 5.1°, respectively, in moderate scoliosis patients; and –5.2° to 5.0° and –6.0° to 4.8°, respectively, in severe scoliosis patients. The Cobb angle measured by the 3 observers twice before and after using the photography method had good repeatability (P<.001). The consistency between the observers was excellent (P<.001).

CONCLUSIONS

The new AI platform is accurate and repeatable in the automatic measurement of the Cobb angle of the main curvature in patients with scoliosis.
Acceptability and utility of an online patient-completed clinical decision aid for the differential diagnosis of transient loss of consciousness: a qualitative interview study (Preprint)
Authors: Wardrope Alistair , Blank Lindsay , Ferrar Melloney , Goodacre Steve , Habershon Daniel , Reuber Markus
Published: October 2024

BACKGROUND

Online patient-completed clinical decision aids (CDAs) have the potential to reduce inefficient resource use and patient risk in acute and emergency settings while minimising additional clinician time burden. However, such interventions must be acceptable for use by their target audience - patients.

OBJECTIVE

To assess acceptability and utility to patients of a novel online patient-completed CDA for the differential diagnosis of transient loss of consciousness (TLOC).

METHODS

Within a larger validation study of a patient-completed CDA, we conducted nested qualitative semi-structured interviews with a purposive sample of 20 patients who used the CDA in the study, and performed thematic analysis of interview transcripts.

RESULTS

We identified 6 themes within the data: 3 addressing the content of the CDA; 3 addressing the online implementation; and 4 addressing usability and acceptability of the CDA. Respondents generally felt an online CDA was easy to complete and acceptable, though felt that increased options to personalise descriptions of their experience would be helpful, and offered guidance on how to make it a more useful resource for patients as well as clinicians. We present good practice points for the design of patient-completed online CDAs on the basis of our thematic analysis.

CONCLUSIONS

Patient-completed CDAs can be accessible and feasible for patients to use in acute and emergency settings. In designing such tools, clinicians should endeavour to maintain their accessibility for all relevant patient groups, and to utilise them to provide direct patient benefit, as well as to support clinical decision-making, e.g. through simultaneous patient-directed outputs.

CLINICALTRIAL

We pre-registered the study protocol on clinicaltrials.gov (ID: NCT05367999).

Justicia climática: avances y retrocesos
Authors: Rosas Barrera Salvador
Published: October 2024

La repartición injusta de las cargas y beneficios derivados de la explotación de la naturaleza, incluidas las capacidades de la atmósfera, ha generado importantes movimientos reivindicativos que luchan por resarcir los males históricos producidos por los países desarrollados y vinculados con el cambio climático. Ante ello, el multilateralismo parecía ser una alternativa viable para lograr la llamada justicia climática. Sin embargo, los resultados se han demorado debido a la influencia del poder económico y político que prevalece en dichos organismos, la dirección y fuerza de los acuerdos internacionales para materializarse. Pese a ello, se observan pequeños pasos hacia la integración de la justicia climática en el discurso, mediante iniciativas concretas y el financiamiento de acciones en países del sur global; y si bien dichos avances pueden generar suspicacia, es un camino difícil que debe transitarse. Por tanto, el objetivo de este artículo es explorar las relaciones de poder entre los gobiernos dentro de los organismos internacionales, la influencia de los poderes políticos y económicos en la toma de decisiones dentro de esos espacios y la operación de diversos mecanismos evasivos de responsabilidad climática por parte de los países más desarrollados.

Results During the period of operation of the play-learning community meeting, pre-questionnaires and post-questionnaires, childcare plans, play implementation reports, research group diaries were collected.
Conclusions Through the play-learning community, daycare center directors changed as follows. First, the directors changed their understanding of the value of play-oriented activities by ‘promoting understanding of play-oriented activities led by children’ and ‘finding common values through worries about the implementation of play-oriented activities’. In other words, the directors realized that learning took place in the process of children's play while considering the composition of play and the environment. Second, the directors practiced play-oriented activities focusing on ‘creating a play-oriented childcare course based on observation’, ‘becoming a director who supports play-oriented activities’, ‘changing the organizational culture of teachers and parents’. In other words, the directors realized that their role should be to create play time, environment, and organizational culture so that teachers can practice play-oriented activities.

Objectives This study aims to construct a research model based on previous studies and to analyze the suitability and structural relationship between research hypotheses and research models to construct a model that can predict the relationship between nursing student's empathy competency and resilience, nursing professionalism, and clinical practice adaptation.
Methods The subjects of the study were 202 nursing students from three universities as a convenience sample, and data were collected using a structured questionnaire. Statistical analysis was performed using SPSS 25.0 and AMOS 25.0 programs and was analyzed using structural equation model (SEM).
Results Results of the significance test of the path coefficient, the direct path from empathy competency to resilience (β=.978, p<.001), resilience to nursing professionalism(β=.381, p<.005) and clinical practice adaptation(β= .897, p<.001) was significant. The direct path from empathy competency to nursing professionalism and clinical practice adaptation was not significant. The significance of the mediating effect was verified through bootstrap, and the indirect effects of empathy competency on nursing professionalism(β=.373, p<.001) and the indirect effects (β=.877, p<.001) on clinical practice adaptation through resilience were verified to be statistically significant.
Conclusions Nursing student's empathic competency had an indirect effect on nursing professionalism and clinical practice adaptation by mediating resilience. Therefore, it was verified that resilience full mediated the effect of empathy competency on nursing professionalism and clinical practice adaptation.

Objectives In this study, we sought to verify the mediating effect of grit in the impact of the organizational culture of early childhood education institutions and the emotional labor of early childhood teachers on professionalism.
Methods For this purpose, a survey was conducted on 371 infant and toddler teachers working in kindergartens and daycare centers in Gyeonggi-do, and the collected data were subjected to frequency analysis, descriptive statistics, correlation analysis, and multiple regression analysis using SPSS 25.0, and the mediation effect was analyzed. The Sobel test was performed to verify statistical significance.
Results First, there was a significant positive correlation between the organizational culture of early childhood education institutions and the grit and professionalism of early childhood teachers, and there was a significant negative correlation between emotional labor. Second, the organizational culture of early childhood education institutions had a positive effect on the professionalism of early childhood teachers, and grit had a mediating effect in the process. Third, the emotional labor of infant and toddler teachers had a negative impact on professionalism, and grit had a mediating effect in the process. This means that there is a direct effect of organizational culture and emotional labor and an indirect effect through grit on the expertise of infant and toddler teachers.
Conclusions It is meaningful that the theoretical basis was expanded through verification of the mediating role of grit along with the importance of organizational culture and emotional labor to improve the expertise of early childhood teachers.
(In)definitude, número e implicatura de multiplicidade em uma língua sub-representada: um estudo do Kaiowá (Tupí-Guarani)
Authors: Guerra-Vicente Helena , Ramires Daiane
Published: October 2024

O ponto de partida para o estudo é o entendimento de que sintaxe, semântica e pragmática atuam de forma simultânea e recursiva na derivação de sentenças. Nossa evidência empírica provém do Kaiowá (Tupí-Guaraní). Apresentamos duas formas pelas quais o plural do Kaiowá pode ser expresso: pela forma básica do nome e pela forma nominal modificada por -kuera, um marcador especial de plural. As duas formas não estão em competição pelo plural. Ambas levam a um plural fraco que inclui o singular em sua extensão. O plural forte não é fornecido de forma gratuita pela lógica, sendo derivado por meio de uma “implicatura de multiplicidade”. Defendemos também que o NP nu do Kaiowá é ambíguo entre interpretações definidas e denotadoras de espécie. Teoricamente, amparamo-nos na visão neo-Carlsoniana de Chierchia (1998) que propõe dois princípios reguladores da mudança de tipo semântico, Blocking e Ranking. O Kaiowá fornece evidência adicional para a versão revisada por Dayal (2004) de Ranking. Nessa última, ∩ e ι estão ranqueados acima de ∃, que só é acionado em último caso. Ao demonstrarmos que o Kaiowá apresenta as mesmas leituras de línguas que possuem artigos no que diz respeito à expressão de número e (in)definitude, sugerimos que essa língua apresenta evidência adicional a favor de uma abordagem localista, que defende que as implicaturas de multiplicidade sejam calculadas passo a passo, na gramática, assim que os termos escalares entram na derivação, em detrimento de uma abordagem globalista, que faz o cálculo sobre a proposição completa, em nível pós-gramatical.
