Since the emergence of Pokémon Go in 2016, the world has been introduced to Augmented Reality (AR) games. Many IT companies have begun developing augmented reality (AR) games due to the great commercial potential in this industry. Certain products may have managed to remain viable in the market, while others were forced to close due to one or two factors. Since the emergence of Pokémon Go, no other game has managed to surpass its unprecedented success. The company responsible for developing Pokémon Go has decided to shut down one of their games due to a lack of consumer interest. The technology of augmented reality (AR) is consistently associated with the concept of immersion. Immersion is a key aspect of the game that allows users to deeply engage and feel fully involved in the experience. This study will employ a quantitative methodology, utilising a questionnaire that will be distributed to and completed by those who have engaged in augmented reality (AR) games. The data will be analysed using Smart PLS to examine the impact of user experience on immersion, which in turn influences intention. After gathering over 200 participants by spreading google form questionnaires and doing data analysis, the findings indicate that only a few aspects of user experience, namely Brand Experience and User Need Experience, have an impact on reasons. Niantic, the developer of Pokémon Go, was unable to replicate their success with a similar augmented reality game called Harry Potter: Wizards Unite. The initial release occurred on June 21, 2019, and the shutdown took place on December 21, 2021. In the beginning, they shown a profound enthusiasm for the game but were unable to sustain it, much as Pokémon Go. According to Niantic CEO John Hanke, the primary reason for the game's shutdown was its immersion. Immersion has a notable impact on User Confirmation, which in turn has a notable impact on Satisfaction, and Satisfaction has a notable impact on Intention. Moreover, there have be

Nephrolithiasis is a common clinical disorder, and calcium oxalate (CaOx) is the principal crystalline component in approximately 75% of all renal stones. It is widely believed that proteins act as inhibitors of crystal growth and aggregation. Acidic amino acids present in these proteins play a significant role in the inhibition process. In this study, interaction of cal-cium oxalate with human phosphate cytidylyltrans-ferase 1(CCT), a novel calcium oxalate crystal growth inhibitor purified from human renal stone matrix has been elucidated in silico and involvement of acidic amino acids in the same. As only sequence of CCT is available, henceforth its 3-D structure was modeled via Homology modeling using Prime module of Schrodinger package. Molecular dynamic simulation of modeled protein with solvation was done by mac-romodel (Schrodinger). The quality of modeled pro-tein was validated by JCSG protein structure valida-tion (PROCHECK & ERRAT) server. To analyze the interaction of modeled protein CCT with calcium oxalate along with role played by acidic amino acids, ‘Docking simulation’ was done using MOE–Dock. Interaction between calcium oxalate and CCT was also studied by substituting acidic amino acid in the active sites of the protein with neutral and positively charged amino acids. The in silico analysis showed the bond formation between the acidic amino acids and calcium atom, which was further substantiated when substitution of these acidic amino acids with alanine, glycine, lysine, arginine and histidine com-pletely diminished the interaction with calcium ox-alate.

In today’s fast-paced digital landscape, accurate and efficient website traffic forecasting is crucial for resource optimization and business operations. Traditional models often struggle to capture short-term trends and patterns in small datasets. This study addresses the urgent need to enhance forecasting accuracy by incorporating Exponential Moving Average, a method known for its responsiveness to recent changes in data, into XGBoost, a highly efficient machine learning algorithm. The research focuses on a dataset of $\mathbf{2, 1 6 7}$ records spanning from September 2014 to August 2020, developing three models with all features including EMA, with selected features, and excluding EMA. These models were evaluated using Mean Absolute Error, Root Mean Square Error, and Mean Absolute Percentage Error. The model with EMA features significantly outperformed the others, achieving an MAE of 111.612, RMSE of 152.931, and MAPE of $1.846 \%$, while the model without EMA had an MAE of 338.904 and MAPE of $5.606 \%$. These results demonstrate the critical role of EMA in capturing dynamic trends in website traffic, making it an essential feature for accurate forecasting in today’s rapidly evolving online environments.

Nanoscience and Nanotechnology (NS-T) are of the most rapidly emerging fields. Manipulation of the matter in the nanoscale has resulted in innovative products and concepts in the macroscale. Biomimetics especially, has utilized NS-T to create pioneering products, such as self-cleaning surfaces, super hydrophobic or hydrophilic materials, based on understanding and handling the wettability of surfaces. Wetting Models are used to describe various wetting states of a surface. Wetting models portray the different ways of a surface's wetting and the way the procedure is actually determined by its micro- and nano- roughness. Although a subject rarely encountered among educational interventions in Biomimetics, it provides fundamental context for comprehending phenomena such as hydro- and oleo- philicity and phobicity, the Lotus Effect, and the Rose Petal Effect. Their introduction is thus considered appropriate to occur in order to establish a solid theoretical background concerning the aforementioned phenomena. In the present study the design of teaching materials about Wetting Models addressed to Secondary Education is being described. To the means of structuring a specific teaching plan based on the instructional model of 5E's, Educational Reconstruction Model (MER) has been utilized. Decontextualizing scientific content and recontextualizing it, taking into account the characteristics and the factors affecting the learning process. As a result, six teaching modules have been created. Learning goals, association with the 9 Big Ideas of NS-T of these modules, as well as misconceptions expected to emerge will be presented. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).

Many biological surfaces are known for their micro- and nanoscale structures, which combined with their hierarchical properties lead to superhydrophobic surfaces. The lotus leaf is the most studied leaf surface that exhibits superhydrophobicity. The knowledge gained by examining its leaf properties helps scientists design superhydrophobic surfaces that benefit humanity on a daily basis. Therefore, there is a necessity to update school science curricula by integrating nanotechnology-related concepts that are both relevant and meaningful to students. This work suggests a proposal for the introduction of superhydrophobicity in secondary education through the development of a teaching learning sequence. Through the MER methodology, the scientific content is analyzed and transformed into a content structure for instruction, defining the learning objectives of each unit through the 5E Instructional Model and considering the difficulties and misconceptions that students may have. The implementation of the educational reconstruction will be presented considering all the parameters involved in the learning process. © Copyright owned by the author(s) under the terms of the Creative Commons Attribution-NonCommercial-NoDerivatives 4.0 International License (CC BY-NC-ND 4.0).
