Authors: Ahmed Mohamed M. , Al Areefy Azza A. , Alsayegh Abdulrahman A.
Published: January 2025

Due to their cognitive and physical impairments, children with autism spectrum disorder (ASD) have detrimental effects on their daily activities. The goals of physical therapy (PT) treatment plans are to lessen impairments to body structure and function, support milestones, and encourage developmental sequence. Neurodevelopmental treatment (NDT) is a sensory–motor approach used by physical therapists/occupational therapists to children and adult function and manage movement disorders due to neurological impairment. No studies until now have focused on the role of the NDT approach of PT on children with ASD. So, the purpose of this study was to investigate the effect of NDT PT approach on the gross motor development and cognition of children with ASD. Forty children with ASD were randomly distributed into two groups: group A (intervention group) for PT, and group B (control group). They were evaluated using gross motor functional measure (GMFM)-66 to measure gross motor skills and Stanford-Binet Intelligence Scales fifth edition (SB5) to measure the intelligence quotient and cognitive variables before and after intervention. Intervention continued for 3 months for children with ASD in the Jazan region, Kingdom of Saudi Arabia. Group A had significant improvements for both gross motor function (P = 0.001) and cognition (P = 0.001), and group B showed no significant change for both gross motor (P = 0.69) and cognition (P = 0.21) while between-groups comparison showed significant improvement in group A for cognition (P = 0.003) and gross motor function (P = 0.003). It was concluded that gross motor development on GMFM-66 and cognitive functions of children with ASD on SB5 significantly improved after a structured individualized NDT PT program for 3 months of daily sessions for 1 h at school age for non-obese children with ASD.

Published: January 2025

Cerium oxide (CeO2) doped with zinc oxide (ZnO) nanoparticles were synthesised using sol-gel method. The impact of CeO2 doping on the microstructure, optical, photocatalytic, and antibacterial properties of ZnO nanoparticles (NPs) were investigated. XRD results showed the presence of both CeO2 and ZnO phases. The ZnO sample crystallizes into a hexagonal wurtzite structure and CeO2 with a cubic structure. The crystallite sizes were estimated and found to be 18 nm and 29 nm for the CeO2 and ZnO, nanoparticles respectively. FTIR spectrum reveals the formation of chemical bonds. The FESEM studies showed the formation of dense crystallites with aggregation. The EDX studies confirmed the presence of cerium, zinc, and oxygen in the sample, and no additional peaks have been detected. The UV-Visible spectroscopy analysis revealed the bandgap of 3.15 eV. The photodegradation activity of the nanoparticles with methylene blue (MB) dye was carried out using visible light irradiation and the degradation efficiency was found to be 75.81 % in 1 h duration. The antibacterial susceptibility test was conducted using the agar well diffusion method to investigate the activity of CeO2 doped ZnO nanoparticles against E. coli, Salmonella typhimurium, Bacillus cereus, and Shigella flexneri, and the results showed significant antibacterial activity as compared to the control drug penicillin.

Der Artikel untersucht Motivationen und Herausforderungen queerer Menschen in Deutschland bezüglich ihrer Politiken der Sichtbarkeit. Trotz des Anstiegs queerfeindlicher Gewalttaten entscheiden sie sich häufig dazu, ihre Queerness sichtbar nach außen zu tragen, getrieben von persönlicher Geschichte und dem Wunsch nach Veränderung. Während die Angst vor Diskriminierung präsent bleibt, motiviert insbesondere der Wunsch nach gesamtgesellschaftlicher Veränderung dazu, vielfältige Sichtbarkeit zu verstärken. Die Untersuchung zeigt, wie komplexe Entscheidungen zur Sichtbarkeit individuell getroffen werden und wirft Licht auf die Vielschichtigkeit queerer Identitäten im Spannungsfeld von Akzeptanz und Risiko.
Duration of Competitive Advantage, Cash Flow Period, and Residual Value
Authors: Forsyth Juan A.
Published: January 2025

This research presents a methodology to estimate the duration of the competitive advantage period (CAP) for companies based on the duration implied in market prices. The CAP is defined as the period during which a company can continue to grow by finding new investment opportunities where the return exceeds the cost of equity. This study applies the methodology to the Standard and Poor’s 500, finding that the average CAP is twenty-one years when assuming that excess returns or competitive advantages gradually extinguish in the years following this period. If we assume that companies maintain their competitive advantage indefinitely for investments made during the CAP, the duration reduces to seventeen years. Additionally, the study provides guidance on the appropriate residual value formula to use based on the CAP and the assumptions regarding the duration of competitive advantage.

Conservation Philosophy After the End of 'Nature'?
Authors: Sandler Ronald L. ,   Center for Environmental Philosophy, The University of North Texas
Published: January 2025

The concept ‘nature’ and the role it has played in conservation philosophy have been criticized on theoretical and ethical grounds. Theoretical critiques include that it is ambiguous and implies a false human-nature dichotomy and/or human exceptionalism. Ethical critiques include that it has been used to justify unjust conservation practices, such as colonial erasure and displacing Indigenous and local peoples from their lands. More recently, the concept has been criticized on the grounds that under conditions of high rate and high magnitude anthropogenic change it is not reliable for guiding effective conservation decision-making. Do these critiques imply theorists and practitioners ought to develop a conservation philosophy without ‘nature’? Drawing from work by Steve Vogel and Sally Haslanger, I advocate taking an ameliorative approach to ‘nature,’ rather than abandoning the concept altogether. ‘Nature’ is not an ontologically privileged category that has special moral or value properties, but sufficiently ameliorated, it nevertheless has a crucial role to play in the future of conservation philosophy.

Authors:   Universidad de Guanajuato, México, Gil Algemiro J. , Torres Zúñiga Ixbalank ,   Universidad de Guanajuato, México
Published: January 2025

In this article, we explore an analytical approach to generate Takagi-Sugeno (TS) type models from ’experimental’ data using the Sparse Identification of Nonlinear Dynamics (SINDy) technique. Our method combines the approximation of reduced nonlinear models with the linearization of the same model at specific operating points, allowing us to capture the dynamics of complex systems under variable conditions for each point of interest. We then present a detailed implementation of this approach, highlighting its application in a real-world scenario of modeling a biotechnological process.

Published: January 2025

This paper presents a model quasi-linear parameter varying (qLPV) and an integral Linear Quadratic Regulator (LQR) controller for an unmanned aerial vehicle type hexarotor. The qLPV model is derived using the nonlinear sector approach, which can accurately represent the hexarotor nonlinear model under bounded nonlinear terms. Meanwhile, the goal of the controller is to achieve trajectory tracking despite disturbances caused by residual rotor speeds and wind disturbances. Trajectory tracking is accomplished by using an integrator comparator block which is divided into three subsystems governed by rotational, altitude and position dynamics. To guarantee robustness against disturbances and tracking error, a H∞ performance criterion is considered. The stability condition and robust performance are formulated using the Lyapunov quadratic function, with sufficient conditions provided by linear matrix inequalities (LMIs). Finally, numerical simulations of the proposed method are illustrated using the hexarotor model.

A Novel Clustering-Based Scheme for Wildfire Monitoring in Flying Ad Hoc Networks
Authors: Visa Samson Bitrus , Sunday Caleb Gasin , Abdulkadir Abubakar
Published: January 2025

This study addresses energy consumption limitations and network overhead in cluster formation within Flying Ad Hoc Networks (FANETs), a type of Wireless Sensor Network (WSN) commonly used for wildfire monitoring. FANETs consist of mobile nodes, represented by Unmanned Aerial Vehicles (UAVs), communicating in a self-organized manner, with clustering playing a crucial role in improving scalability and resource management. This work proposes an Energy Efficient Wildfire Monitoring Scheme (EEWMS) to optimize Cluster Head (CH) selection and reduce the energy costs of cluster formation. The scheme incorporates node remaining energy, trust level, energy consumption, base station proximity, mobility, and CH coverage into a fitness function for intelligent CH selection. EEWMS was validated through simulations in the MATLAB environment, comparing its performance against existing techniques, specifically EE-SS, using metrics including energy consumption, network lifespan, and cluster formation time. The results demonstrate that EEWMS significantly enhances FANET performance, reducing cluster building time by 10.16%, increasing cluster lifetime by 6.96% and improving energy efficiency by 10.25%. These improvements underscore EEWMS's effectiveness in enhancing real-time wildfire monitoring by improving network responsiveness, extending operational periods, and ensuring reliable data transmission. The findings provide a robust solution to energy and scalability challenges, making FANETs more efficient and reliable for emergency response applications.

In order to assess the impact of Waqf in sectors including education, healthcare, poverty reduction, and infrastructure development, the study uses both qualitative and quantitative data gathered through surveys, interviews, and document analysis. In order to highlight excellent practices and issues, case studies of prominent Waqf foundations in Nigeria are given, together with their accomplishments and shortcomings. The results show that although Waqf institutions have made important contributions to community service, issues including tax regulatory frameworks, low public awareness, and subpar management techniques have prevented them from reaching their full potential. The report emphasizes that in order to improve the operation of Waqf institutions, legal reforms, capacity training, and public-private collaborations are necessary. With a focus on its alignment with the Sustainable Development Goals (SDGs), the study ends by offering a roadmap for utilizing Waqf as a tool for sustainable development in Nigeria. There are suggestions on how civil society, religious institutions, and government agencies might work together to revive Waqf institutions for efficient community service delivery, which would eventually support social cohesion and national growth.

This study examines the effect of public administration transparency on public trust in Indonesia. Using a quantitative approach, data were collected from 50 respondents through a structured questionnaire employing a Likert scale of 1 to 5. The data were analyzed using SPSS version 26, and regression analysis was used to determine the relationship between transparency and public trust. The findings indicate a significant positive relationship between public administration transparency and public trust, with an R-squared value of 0.452. This suggests that approximately 45.2% of the variance in public trust can be explained by transparency. The results highlight the importance of improving openness, accessibility, and accountability in government to enhance public trust. This study provides valuable insights for policymakers seeking to foster greater trust through improved transparency in Indonesia's public administration.

Published: January 2025

This study was conducted to determine the existence of subsurface aquifers and the distribution of groundwater-surface depth in Jayawijaya Regency, Mountainous Papua Province. The background of this research is the need for optimal groundwater management in areas with high topography such as Wamena City. The method used was a geophysical survey with the Wenner-Schlumberger configuration resistivity geoelectric technique to identify the aquifer layer. Primary data was obtained through direct measurements using geoelectric devices and GPS, while secondary data was obtained from related literature. The results showed that there were free aquifers with a depth of 25-105 meters and depressed aquifers at a depth of 145-270 meters in various research locations. The distribution of this aquifer is highly dependent on local geological conditions, with the availability of groundwater quite high in some areas and minimal in other areas such as Kampung Sabulama and Wasawa. In conclusion, the resistivity geoelectric method is effective for mapping the distribution of aquifers, which can further be used as a basis for groundwater management in the study area.

Authors: Sudirman Sudirman , Suprapto Heri
Published: January 2025

Tirta Asasta Depok has made the Independent Smart Drinking Water Platform which is prepared as a special program that is placed in public places. Currently, there are 3 (Three) Independent Smart Drinking Water Platforms installed throughout the Depok City area. The Mandiri Smart Drinking Water Platform aims to be a facility that can be enjoyed by customers in particular and the general public so that they can enjoy the processed water of the Mandiri Smart Drinking Water Platform. The installation of this machine is a form of effort by PT. Tirta Asasta Depok (Perseroda) in order to encourage the people of Depok City to be able to reduce bottled water consumption so that they can reduce the contribution of waste in the Depok City environment. People can use tumblers to buy drinking water, so that plastic bottle packaging waste can be minimized. Therefore, it is necessary to evaluate the effectiveness of the use of the Mandiri Smart Drinking Water Platform that has been installed and the potential for the installation of the Mandiri Smart Drinking Water Platform program in the future so that it becomes a consideration for the installation of the Mandiri Smart Drinking Water Platform which will be planned next. The results of the evaluation of the use of this machine still need control and regulation as well as official levies. The installation of this machine has a lot of water consumption opportunities in schools. Based on the weighting assessment that has been calculated, there are 9 (nine) agencies and schools that can be recommended (with a total value of > 15.00 points).

Published: January 2025

Building Information Modeling (BIM) is one of the technologies in the field of AEC (Architecture, Engineering and Construction) that is able to simulate all information in a development project into a 3D model. Research in this thesis was carried out to analyze the results of the implementation of Building Information Modelling (BIM) 5D in dock work (Quay Wall Structure) by paying attention  to clash detection at the pre-construction stage, with a case study of the Patimban Port Project Package 6. The focus of the research is the application of BIM 5D in identifying and resolving design clashes that can have an impact on the estimation of work volume and cost. The method used is qualitative and inductive analysis using Tekla Structure 2021 BIM software for 3D modeling and clash detection identification. The results of clash detection identification are grouped into three categories, namely large, medium, and small. The implementation of BIM 5D shows significant volume changes in some work items. The volume of the Deck Slab (Pier Head) and Front Wall decreased compared to the initial RAB, while the volume of the Deck Slab (In-Situ Concrete) increased. The cost comparison shows a savings of 7.06% of the total initial cost of RAB Quay Wall Structure, which is equivalent to IDR 10,502,919,303.55. The implementation of BIM 5D by conducting clash detection is quite effective in identifying and resolving design clashes, mitigating errors and revisions when entering the construction stage, and can increase project efficiency in better communication and coordination.

I joined Twitter1 way back in 2009. For nearly 10 years “scitwitter” was an amazing place for discussion, discovery, and engagement with the scientific community. The #Rstats and #pydata hashtags were great places to learn about something new in programming, #icanhazpdf was great for getting papers you didn’t have access to, and conference live-tweeting was common and useful for those of us with FOMO not able to make it in person.
Use nanoparquet instead of readr/CSV
Authors: Turner Stephen
Published: January 2025

Yesterday I wrote about base R vs. dplyr vs. duckdb for a simple summary analysis. In that post I simulated 100 million rows of a dataset and wrote to disk as CSV. I then benchmarked how long it took to read in and compute a simple grouped mean. One thing I

didn’t

do here was separate the time it took to read data into memory (for base R and dplyr) versus computing the actual summary.
Impacts of wind turbine characteristics on wake turbulence
Authors: Wang Shifeng , Wang Sicong
Published: January 2025

The enhanced wake turbulence generated by wind turbine has remarkable effects on the power generation and fatigue loads of wind farm and the environment. The paper investigates the mechanism of the impacts of the wind turbine characteristics on the wake turbulence, to provide new knowledge on the design of wind turbine to wind turbine manufacturing factories. A novel wake turbulence coefficient is developed to quantify the ratio of the generated turbulence kinetic energy to the captured wind energy, and is derived as the function of wind turbine characteristics. This wake turbulence coefficient model is explored under optimal conditions. Results show that the wake turbulence coefficient decreases sharply with the increasing power coefficient of wind turbine. The larger the power coefficient is, the smaller the decrease of wake turbulence coefficient. Therefore, it is an effective way to reduce the enhanced wake turbulence through increasing the power coefficient, especially when the power coefficient is small. The wake turbulence intensity is the strongest around the hub of rotor and the weakest around the tip of rotor. It is therefore important to design the structure of the hub of rotor to reduce the enhanced wake turbulence.
