Simulating computed tomography (CT) systems offers numerous advantages, including the optimization of scan parameters, training of specialist personnel, and quantification of measurement uncertainties. Current simulation approaches, often referred to as virtual computed tomography (vCT), predominantly rely on analytical models. However, these models require extensive system-specific tuning to produce realistic synthetic measurements, creating a significant barrier to broader adoption and efficiency. To address this challenge, this work explores the potential of implicit neural representation (INR) as an alternative to the analytical models used in vCT. INRs excel at representing complex, high-dimensional data in a continuous and differentiable manner, making them a promising substitute for traditional analytical models. As a first building block, we propose a two-stage approach for simulating the X-ray beam energy and detector signal processing in industrial CT systems. This method is trained and evaluated using real-world data. Results demonstrate that the proposed INR-based architecture can accurately generate synthetic projections for parameter configurations within the training dataset. However, its poor performance on the test dataset highlights limitations in generalization beyond the training data. Potential methods to address these shortcomings are discussed. This study underscores the potential of INRs as a flexible framework for simulating complex CT systems. By capturing subtle system-specific characteristics and reducing dependence on explicitly defined parameterizations, INRs could pave the way for more versatile and efficient simulation models.

The formation of fibre breaks governs the longitudinal tensile failure of a unidirectional ply. It is widely believed that matrix plasticity, matrix cracking, and fibre-matrix debonding created near these fibre breaks help reduce the resulting stress concentrations. Therefore, to determine if matrix cracking and fibre-matrix debonding surrounding fibre breaks occur in a glass fibre-epoxy composite, we performed in-situ tensile tests combined with holotomography at a resolution of 150 nm. Despite their presence in single-fibre composites manufactured with the same constituents, they were absent in regular composites. This suggests that single-fibre composites are not representative of regular composites. The study provides fresh insight into the damage mechanisms in these materials.

The accurate measurement of flow parameters often depends on sensor accessibility. Optical flow assessment techniques, such as Particle Image Velocimetry (PIV) and Particle Tracking Velocimetry (PTV), are limited to optically transparent media. However, many industrial processes involve opaque media, necessitating alternative methods. This study presents the development and application of X-ray Particle Tracking Velocimetry (XPTV) to investigate flows within such media. Specifically, the flow inside a nozzle of a Fused Filament Fabrication (FFF) printer was examined. A novel contribution of this work is the first-time analysis of heated flow using XPTV, achieved by introducing tungsten powder as a contrast agent in the polymer flow. The study successfully visualized a parabolic velocity profile, demonstrating the method’s efficacy.

Uncertainty of Law Regarding Restitution as Legal Protection for Child Victims of Sexual Violence
Authors: Aryanti Merry , Suparno Suparno
Published: January 2025

This study examines the legal uncertainty related to the implementation of restitution as a form of legal protection for child victims of sexual violence. The issues raised include unclear regulations, complicated administrative procedures, and lack of support from law enforcement officers in the process of submitting and fulfilling restitution. These conditions often prevent victims from obtaining compensation that is their right according to court decisions that have permanent legal force. This study aims to analyze the legal uncertainty related to the implementation of restitution for child victims of sexual violence in Indonesia, identify obstacles in its implementation, and provide recommendations for improving the existing legal system to create better legal certainty.
This study uses a normative legal method with a statute approach and a case approach. The results of the study indicate that legal uncertainty regarding restitution for child victims of sexual violence is caused by ambiguous regulations, inconsistencies between applicable regulations, and complicated administrative procedures. Support from law enforcement officers, especially public prosecutors, is often less than optimal in facilitating restitution applications by victims. In addition, limited socialization regarding victim rights exacerbates uncertainty in the implementation of the law.
This study provides theoretical and practical implications in the development of criminal law and child protection. Theoretically, this study enriches the criminal law literature related to victims' rights and the implementation of restitution. Practically, the results of this study can be a reference for policy makers in formulating clearer and more implementable regulations. The proposed recommendations include simplifying administrative procedures, strengthening the role of prosecutors, and increasing the socialization of victims' rights to create a more responsive and equitable legal system.

Exploring the Natural Ventilation System of Biomimetic Solar-Powered African Termite Mounds Using Computer Simulated Models for Varied Building Configurations
Authors: Juanga Jean Marie Villamor , Jumawan Hazel U.
Published: January 2025

With the drastic increase in energy consumption and CO2 emissions in recent decades, there is an urgent need for more efficient buildings. To aid in these efforts, this research explored a biomimetic approach to building ventilation by analyzing the natural ventilation system in solar-powered African termite mounds (ATM) using nine building configurations with the aid of Computational Fluid Dynamics (CFD) software. Eight different building orientations were simulated, each with two wall opening percentages, and two building depths, and applied to both midrise and high-rise structures.  Results show that operative temperatures of the ATM ventilation systems were significantly lower compared to the conventional models by seven degrees. Additionally, there is a consistent result of lower wind velocities for the ATM ventilation system in all types of building footprints tested. The bio-mimetic approach with the ATM-inspired ventilation system provides a practical blueprint for an energy efficient future in building ventilation system design.

Authors: Kuswandani Faisal , Balafif Felisha Febriane , Najmi Nuroh , Rafisa Anggun
Published: January 2025

Oral ulcers are a prevalent clinical condition with multifactorial etiologies, including trauma, infections, systemic diseases, and immune dysregulation. Sirtuins, particularly SIRT1, play an important role in regulating oxidative stress, inflammation, and cellular repair pathways. This rapid review, conducted using the PRISMA protocol, synthesizes current evidence on the role of sirtuins in oral ulcer pathophysiology and their potential as therapeutic targets. A comprehensive search identified 140 articles in PubMed, 41 in ScienceDirect, and 4 in the Cochrane Library, of which 1 study met the eligibility criteria. The findings indicate that SIRT1 expression in the oral ulcer rats model is significantly lower than in normal controls, whereas NF-κB and TNF-α levels are markedly elevated in the control group. Pharmacological activation of SIRT1 attenuates inflammation, highlighting its therapeutic potential. However, the limited sample sizes and the lack of clinical trials specifically addressing oral ulcers restrict the generalizability of these findings. Additional study is needed to validate these findings and investigate SIRT1-targeted treatments.

Authors: Chen Xiuli , Ryoo Joohan
Published: January 2025

This study explores the perceptions, adoption, and applications of AI in healthcare among regional health professionals in Guangdong, China. It seeks to determine how health professionals view AI, its application in practice, and the different challenges practitioners face regarding its application. The research applies a survey approach in which 204 medical practitioners’ perceptions and ideas on AI applications were collected. This involves using Pearson Chi-square tests to examine whether roles as professionals correlate with their attitudes toward AI, such as trust in its reliability and effectiveness, its influence on the accuracy of diagnosis treatment plans, and the impact of specialized training on confidence in handling faulty AI tools alongside descriptive analysis. The outcomes reveal variations across such respondent-role groups concerning views on AI and trust, where they are more involved in the diagnostic exercise, and treatment planning groups show higher levels of optimism about the impact of AI. Furthermore, the findings exhibit a close association between specialized training in AI and increased confidence levels when utilizing AI tools, emphasizing the significance of directed learning interventions. However, this study is based on self-reported data that biases may influence and only focused on the Guangdong province in China. A strategic integration approach for patient care and operational efficiency through this technology has been recommended, particularly within China and the broader Asia-Pacific region.

En lo que respeta a los resultados de la investigación, sobre los Factores socioculturales que inciden en la desnutrición infantil de la etnia wayuu en el departamento de La Guajira, se puede afirmar, que este grupo étnico, enfrenta una serie de factores de riesgo que impactan negativamente en la calidad de vida de las familias afectadas, entre las cuales la falta de acceso al agua potable y dificultades socioeconómicas contribuyen a aumentar las altas tasas de enfermedad y mortalidad. Además, la cosmovisión wayuu, comprende un conjunto de creencias, valores y prácticas culturales únicas, presenta implicaciones socioculturales significativas que deben ser consideradas tanto por las autoridades gubernamentales como por las organizaciones no gubernamentales al abordar la desnutrición infantil. Esta cosmovisión influye en aspectos como los patrones alimenticios, el uso de recursos naturales, y las prácticas de salud y cuidado infantil, lo que puede afectar la efectividad de las intervenciones externas si no se toman en cuenta estas particularidades culturales.

En la actualidad los sistemas educativos se enfrentan a retos significativos para la formación de los ciudadanos debido a la evolución de las tecnologías informáticas. Se evidencia a nivel mundial la incorporación de políticas orientadas al desarrollo de competencias digitales desde niveles iniciales de formación. Una de esas competencias es el pensamiento computacional, el cual se concibe como un constructo compuesto de habilidades vinculadas a la creatividad, la resolución de problemas, la colaboración y el pensamiento algorítmico. Desde la última década se evidencia un crecimiento significativo de la productividad científica en esta área desde las dimensiones: fundamentación conceptual, operacionalización, estrategias de aprendizaje y la evaluación. Se identifica el escenario para realizar investigaciones que permitan conocer como se ha implementado el proceso de enseñanza-aprendizaje de pensamiento computacional en diferentes niveles de formación y las tendencias en este objeto de conocimiento. El propósito del presente trabajo está orientado a un estudio bibliométrico que abarca artículos de investigación desde el año 2014 hasta el 2024 y mediante el cual se presentan variables de interés, estrategias de aprendizaje, habilidades, instrumentos de evaluación y herramientas tecnológicas relacionadas con el pensamiento computacional. El estudio muestra que las estrategias más utilizadas son el aprendizaje basado en juegos y el aprendizaje colaborativo. Con relación a las habilidades se identifica una tendencia a desarrollar la programación y la resolución de problemas. La herramienta más usada para el desarrollo de habilidades es Scratch y los instrumentos más usados para la evaluación son el test, la encuesta y la escala.

Las empresas que sirven como proveedores en el sector de la construcción (como en el caso de la que es objeto de estudio en esta investigación) se enfrentaba a un problema serio: un desorden generalizado en sus inventarios. Esto generaba retrasos en las entregas, quejas de clientes y pérdidas económicas considerables. Para abordar este contexto, se decidió usar la una Propuesta de mejora basada en el modelo EOQ (Economic Order Quantity) con demanda probabilística para minimizar el costo total de inventarios de la empresa, Poswal (2022).

El proceso comenzó con una evaluación profunda del estado actual del proceso, determinando los factores desencadenantes del desorden y los costos asociados a la ineficiencia. Luego, se diseñó un plan de acción que incluía el poner en marcha un sistema para predecir la demanda, determinar los niveles de inventario ideales y formar al personal en el manejo de indicadores de gestión.

El uso de un esquema de inventarios del tipo EOQ y las medidas complementarias no fue fácil, pero con el esfuerzo y la determinación del equipo, se reformó radicalmente la administración de existencias en la empresa, optimizando los tiempos de entrega, reduciendo las reclamaciones de los clientes y logrando una notable disminución de las pérdidas económicas. La empresa se convertirá en un ejemplo de gestión eficiente, demostrando que, con planificación, organización y trabajo en equipo, es posible superar los desafíos y alcanzar el éxito. Es por ello que el propósito de este proyecto es diseñar una propuesta para la mejora del aprovisionamiento y gestión de inventarios a partir de un modelo EOQ con demanda probabilística en una empresa del sector de la construcción de la ciudad de Cartagena.

Purpose: The purpose of this quality improvement project was to evaluate the use of a posttransplant screening care guidelines template performed by advanced practice providers (APPs) that included standards of care and published recommendations from the American Society for Transplantation and Cellular Therapy (ASTCT) for adult allogeneic transplant patient survivors. Methods: The theoretical framework used for this project was the Model for Improvement with the Plan-Do-Study-Act (PDSA) cycle process. A screening template was built to include institutional standards of care and recommendations from the ASTCT’s guidelines within the electronic medical record system for APP use. Weekly chart reviews were performed for data extraction and assessment for APP documentation and completion of day +30 and day +100 posttransplant recommended screenings/testing. Data were documented and tracked utilizing Excel securely over a 3-month period. Results: The APPs performed and documented the recommended screenings for 64% of patients at day +30 and for 80% of patients at day +100. Opportunities for unit and system improvements were identified to increase performance, expand utilization, allow clinicians to recognize complications earlier, and potentially improve patient outcomes. Conclusion: This project addresses implications for APP care delivery and patient outcomes. Future project cycles’ success will be ensured by utilizing the APP role at the maximum scope of practice.

Hematopoietic stem cell transplantation (HSCT) is an intensive treatment requiring the support of a caregiver. This role is a highly demanding responsibility, and caregivers often face distress. In a world that has become highly technological, the aim of this integrative review is to determine the availability and impact of remote interventions in reducing distress in caregivers of HSCT patients. A literature review was conducted using PubMed and Scopus databases. The search included articles published between January 1, 2013, and February 20, 2023. The search yielded 699 unique articles, of which four were included in the final review. The four included studies of the impact of remote interventions on distress or burden in caregivers of adult HSCT patients. Two organizing themes emerged: availability and impact. Availability encompassed intervention accessibility and delivery type while impact considered caregiver quality of life (QOL), mental health, and perceived usefulness. These themes were evaluated in the articles via a variety of validated assessment tools and structured interviews. Ultimately, this integrative review suggests that while remote interventions for caregivers of patients undergoing HSCT are relatively limited, initial studies are perceived as useful and are promising in their potential to improve caregiver QOL and mental health and reduce distress.
