Evolution of Endodontics: Innovations in Instrumentation, Irrigation and Filling
Authors: Fasah Elias
Published: January 2025

Endodontic treatment underwent a remarkable evolution from its beginnings, moving from rudimentary and painful techniques in the 18th and 19th centuries to advanced and specialised procedures in the 20th and 21st centuries. Pierre Fauchard described the first attempts at pulp extraction in the 18th century, while the 19th century saw the development of more efficient hand files, such as those designed by Charles Maïsse, which facilitated the cleaning of root canals. In the 20th century, technological advances transformed endodontics with the discovery of the importance of disinfection. Antibacterial irrigants such as sodium hypochlorite and EDTA were introduced, along with innovations in ultrasonic and laser activation techniques. In addition, rotary instrumentation with nickel-titanium alloys revolutionised procedures, allowing curved canals to be approached more safely and effectively.The development of obturation materials such as thermoplastic gutta-percha and improved sealants contributed to more effective and durable obturation. Also, the integration of digital technologies such as radiovisiographs optimised diagnosis and treatment planning, improving patient experience and clinical outcomes. In conclusion, progress in endodontics has made it possible to overcome anatomical and biological challenges, reducing complications and increasing treatment success rates. This progress, based on technological innovation and the improvement of techniques, consolidated modern endodontics as a speciality oriented towards dental preservation and the continuous improvement of oral health.

Muscular Dystrophies and Therapeutic Potential of Medicinal Plants
Authors: Saeed Mohd , Tasleem Munazzah , Haque Ashanul , Shoaib Ambreen , Rizvi Syed Mohd Danish
Published: January 2025

Muscular dystrophies (MDs) are an array of inherited disorders characterized by progressive muscle weakness and degeneration. This review explores the genetic foundation, pathophysiological mechanisms, current treatments, and therapeutic potential of medicinal plants for MDs. Although gene therapy, exon-skipping, and stem cell therapies are substantial advancements, they encounter obstacles regarding immune responses, long-term efficacy, and delivery efficiency. A promising complementary approach to conventional MD therapies is presented by natural compounds from medicinal plants. Recent studies and historical use underscore the multi-targeted effects of phytochemicals, such as resveratrol, withaferin A, ginsenosides, curcumin, and epigallocatechin gallate, on muscle regeneration, oxidative stress, and inflammation. These compounds have demonstrated potential in pre-clinical studies to enhance muscle function, reduce inflammation, and reduce oxidative stress. Despite their potential, the utilization of medicinal plants in MD treatment is impeded by regulatory hurdles, potential side effects, variability in bioactive compound concentration, and standardization issues. To address these challenges, it is necessary to implement rigorous clinical trials, standardization protocols, and comprehensive quality control measures. Future research should focus on elucidating the molecular mechanisms of plant-derived compounds, improving biotechnological production techniques, and integrating these treatments into personalized, comprehensive treatment plans. Advances in synthetic biology, genomics, metabolomics, and nanoformulations have the potential to improve the efficacy and safety of phytomedicine in the treatment of MD. Implementing evidence-based integrative approaches can enhance holistic care, improve patient outcomes, and facilitate acceptance of medicinal plant-based therapies in clinical practice.

Published: January 2025

Multiple long-term conditions (MLTCs or multimorbidity) are becoming more prevalent with the aging population and are associated with poor health outcomes and quality of life, such as declined physical functions resulting in physical disability. However, limited research has examined the association between MLTCs and physical disability. Therefore, the aim of this scoping review was to summarize previous studies related to the association between MLTCs and physical disability using cross-sectional and longitudinal designs. A search was made using PubMed, Google Scholar, and Web of Science from inception to June 2024 to identify studies. Eligible studies should have defined disability and MLTCs/multimorbidity. Two reviewers independently performed the search and data extraction. The studies were categorized as cross-sectional and longitudinal designs. A total of 20 studies were included in this review. Ten studies were cross-sectional with sample sizes ranging from 100 to 31,464 participants. Ten studies were longitudinal designs with sample sizes ranging from 1751 to 16,616 participants. Age was variable across all studies ranging from 18 to 85 years with the focus on older adults in the majority of the included studies. MLTC definitions varied across studies with the majority of the studies defining MLTCs as having two or more chronic conditions. Disability definitions were different across studies with the majority reporting on activities of daily living. All of the included studies found a significant association between MLTCs and disability in cross-sectional and longitudinal studies indicating that an increased number of chronic conditions was associated with a greater level of disability. In conclusion, this study highlights that MLTCs and disability have a strong association, including over long-term follow-up. Limitations should be considered such as the definitions of MLTCs and disability that have variability across studies.

Theoretical Design of Asymmetric/symmetric Nanodisk Arrays Deposited on GaAs Film for Plasmonic Modulation and Sensing
Authors: SUN Cheng , YANG Xue , LI Xinyu , CHU Shuwen
Published: January 2025

Metallic plasmonic nanostructures can achieve nanoscale light-matter interactions and have a wide range of applications in spectral modulation and optical sensing fields stemming from their rich and tunable optical properties. Herein, we propose a composite nanostructure consisting of a gold nanodisk array and a GaAs thin film, which achieves symmetric and asymmetric configurations by adjusting the nanodisk radius of the array structure. We systematically investigate the relationship between plasmonic modulation and asymmetric/symmetric coupling modes. The results indicate that the two configurations correspond to single resonance and dual resonance, respectively. The short wavelength of the dual-resonant mode is jointly excited by the local surface plasmon polariton (LSP) mode of the nanodisk itself and the waveguide-hybridized lattice mode of the bottom GaAs film. And the long wavelength corresponds to the LSP mode of the array nanostructure which strongly depends on its size.  Improving structural symmetry leads to different trends in resonance wavelength. Furthermore, we investigate the sensing performances for asymmetric/symmetric nanodisk arrays. This work is of great significance for applications such as multi-resonance sensing, plasmonic modulation, etc.

Entre estos, nos ocupamos de la representación del “escorpión” o “alacrán”, presente entre las manifestaciones de tradición neolítica y líbico-amazigh. En el presente trabajo exponemos tres ejemplares de estos arácnidos situados en contextos iconográficos heterogéneos y donde aparecen como un elemento singular. Desde el inicio del Neolítico, en el Oriente Próximo, el escorpión destacó como un componente simbólico, el cual se difundió entre las antiguas civilizaciones sumeria y egipcia, así como en la griega y romana, y también entre las culturas americanas, citemos la maya y azteca en México o las del sudoeste de Estados Unidos, entre otras muchas. Su notoriedad ha sobrevivido en distintas regiones del planeta hasta la actualidad.
En este artículo, nuestro interés es poner en valor estos sitios y avanzar en la comprensión del papel adquirido por estos arácnidos, así como evaluar sus contextos gráficos, establecer relaciones con otras áreas geográficas y enmarcar su posible horizonte crono-cultural.

This research aims, through a risk analysis, to estimate how the distress caused by Covid-19 affected the relationship between Brazilian sectors and the stock market as a whole, by the CoVaR Model. Daily data of sectors indices of [B]3 and the Ibovespa were collected. It should be noted that almost all sectors showed a significant increase in the contribution at risk in the first year of the crisis, showing a significant impact in all sectors. In relation to the financial sector, it was found that its systemic risk was controlled in the second year of the pandemic. The results indicate that regardless of times of crisis, there must be constant monitoring of the financial and non-financial sectors regarding their systemic risk, since this type of risk, despite not occurring frequently, generates a relevant impact in the economy.

Assessing the Correlation Between Digitalization and Economic Performance: An Empirical Analysis for European Countries
Authors: Mourou Ensem
Published: January 2025

The rapid evolution of information and communication technology (ICT) has resulted in significant transformations across a wide range of social and economic activities. As a result, the ongoing digitalization process is emerging as a critical force in determining progress and modernity. This study looks at the complex relationship between digitalization and economic growth in European Union (EU) countries from 2017 to 2022, using the Digital Economy and Society Index (DESI) issued by the European Commission. Our work employs a sophisticated panel data estimate approach and the fundamental Cobb-Douglas model and presents an empirical perspective on the relationship between digital technology and economic prosperity. Based on the fixed-effect panel estimate, our findings show a significant correlation: A 1% rise in digitalization (as measured by the DESI index) correlates with a 0.3838% impressive rise in GDP growth. This study emphasizes the need to comprehend and utilize digital technologies' revolutionary potential. It presents a solid argument for stakeholders and governments to embrace digital innovation and leverage it to achieve long-term, sustainable economic growth.
A Controller Design for Evaders Considering Single Integrator Dynamics
Authors:   Instituto Politécnico Nacional, México, Mera Manuel , Ríos Héctor ,   Tecnológico Nacional de México, La Laguna, México, Efimov Denis ,   Université de Lille, Francia
Published: January 2025

This paper presents a novel controller for the evader in the pursuit–evasion game, when each player is modeled as a single integrator. The resulting control design does not require any information on the pursuer control, only requires information on the pursuer state. The resulting control ensures the escape of the evader from the pursuer under an adequate selection and design of the evader controller parameters. Additionally, the synthesis of this controller is constructive and can be tuned straightforwardly since it is obtained from the solution of an LMI. The stability analysis of the tracking error dynamics is carried out considering a Lyapunov–like function and the effectiveness of the proposed result is illustrated through some simulations.

This paper presents the design of an observer for a nonlinear model that describes the I and II Types of Diabetes Mellitus. The model includes a sigmoid function to represent the behavior of a discontinuous nonlinear function. Therefore, we give the conditions for the required gains for the observer’s convergence.
Stability Analysis for a Prostate Cancer Model with Distributed Delay
Authors:   CINVESTAV, México, Ortiz Reynaldo , Saldívar Martha Belem ,   CINVESTAV, México
Published: January 2025

Some mathematical models of infectious diseases or cancer use time delays to consider the influence of past states in their evolution, models that include distributed delays are more realistic since they take into account all the states in a time interval in the past. In cancer models it is convenient to know the parameter ranges for which the model is stable in the presence of a tumour. We use tools like an stability criterion depending on the delay Lyapunov matrix and a computational program to determine the roots of the characteristic equation of the linearized model.

An observer-based control is designed using the feedback linearization strategy for blood glucose regulation using a model of the glucose-insulin system that represents a person with type 1 diabetes. The design of two nonlinear state observers are performed; a high-gain observer and a nonlinear observer for Lipschitz systems. The results of the estimated state variables are compared, as well as the control based on each of the observers and the action of the control law for insulin application.

Published: January 2025

The presence of ammonium and its derivatives in drinking water sources is a problem of worldwide concern. This work introduces a formal framework to model and analyze an ion exchange process for ammonium removal commonly used in drinking water treatment. The work aims to evaluate (via simulation) the breakthrough curves for ammonium removal in a fixed-bed column with zeolites operating in upflow regime. The results show quantitatively the influence of the initial ammonium concentration and the flow velocities on the behavior of the breakthrough curves. With this, the proposal is intended to be a reference framework for designing experiments in ion exchange processes for ammonia removal and further optimizing them using control strategies.
Bl-homogeneous observers for differentially uniformly observable LTV systems with a single output
Authors:   Universidad Nacional Autónoma de México, México, Meléndez-Pérez René , Moreno Jaime A. ,   Universidad Nacional Autónoma de México, México
Published: January 2025

This paper presents a methodology for the design of observers for a family of Linear Time Varying systems with a single output satisfying a differential uniform observability property. To address the problem, an immersion of the original system in a higher-dimensional state space is proposed, where a bl-homogeneity (homogeneity in the bi-limit) based state observer is designed with theoretically exact convergence in finite-time. Furthermore, it is shown that, according to the selection of a set of parameters and gains, the convergence is in fixed-time.
Formation Tracking of Unicycle Mobile Robots Using Super-Twisting
Authors:   Instituto Politécnico Nacional, México, Díaz Yoshua , Dávila Jorge ,   Instituto Politécnico Nacional, México
Published: January 2025

This article introduces a distributed control approach for unicycle mobile robots in a leader-follower configuration, ensuring a specific geometric arrangement on the horizontal plane. The proposed control algorithm allows the formation of the follower robots relative to the leader using a super-twisting sliding mode controller even in the presence of disturbances. This method employs a pair of sliding variables and a continuous control signal, ensuring that the sliding variables converge to zero within a finite time. The specific formulation of these sliding variables guarantees that the formation errors converge asymptotically to a bounded region around the origin.
