Software effort estimation (SEE) is an important process for predicting the effort required to develop or maintain software projects. It is considered one of the difficult challenges for software engineering because the more accurate the estimation, the greater the chances of success in developing software projects to complete and deliver them within the specified scheduling and budget. The diversity in software projects led to the use of many techniques to estimate the effort. The main objective of the research is to find the best technique to get the estimated effort as close to the real effort, using Machine learning Algorithms, artificial neural network Long Short-Term Memory(LSTM) and the artificial neural network Stacked Long Short-Term Memory (Stacked_LSTM), with six data sets are China, Kitchenham, Kemerer, Cocomo 81, Albrecht, Decharnais, and comparing the performance of the two machine learning algorithms performance, Neuralnet and Lasso from previous research, used the same data sets and using the same evaluation metrics, which are: the root mean square error (RMSE), mean absolute error (MAE) and R_Squared. The results demonstrated the superiority of the Stacked _LSTM algorithm by all metrics with the dataset of China, Kemerer and Albrecht, while in the data sets, Descharnais and Kitchenham, the LSTM algorithm outperformed the rest of the methods. While in the Cocomo 81 dataset, Neuralnet algorithm outperformed the rest of the techniques used, but the best rating was obtained. It is for Stacked _LSTM algorithm with China data. © 2022 IEEE.

The discovery of miRNAs had great impacts on traditional biology. Typically, miRNAs have the potential to bind to the 3'untraslated region (UTR) of their mRNA target genes for cleavage or translational repression. The experimental identification of their targets has many drawbacks including cost, time and low specificity and these are the reasons why many computational approaches have been developed so far. However, existing computational approaches do not include any advanced feature selection technique and they are facing problems concerning their classification performance and their interpretability. In the present paper, we propose a novel hybrid methodology which combines genetic algorithms and support vector machines in order to locate the optimal feature subset while achieving high classification performance. The proposed methodology was compared with two of the most promising existing methodologies in the problem of predicting human miRNA targets. Our approach outperforms existing methodologies in terms of classification performances while selecting a much smaller feature subset. © 2012 Springer-Verlag.

Despite the huge efforts to develop and administer vaccines worldwide to copewith the COVID-19 pandemic, misinformation spreading through fake news in mediaand social networks about vaccination safety, make that people refuse to bevaccinated, which harms not only these people but also the whole population. In this work, we model the effects of harmful information spreading inimmunization acquisition through vaccination. Our model is posed for severalfractional derivative operators. We have conducted a comprehensive foundationanalysis of this model for the different fractional derivatives. Additionally,we have incorporated a strength parameter that shows the combined impact ofnonlinear and linear components within an epidemiological model. We have usedthe second derivative of the Lyapunov function to ascertain the detection ofwave patterns within the vaccination *** Codes 26A33, 34A08, 35R11 Copyright © 2025, The Authors.

Current focus of sensor networks is on systems dedicated for a specific application. Wide variety of circumstances point to the need for sensor network deployments capable of sharing the physical network resources. We introduce the concept of Virtual Sensor Networks (VSN) to provide protocol support for the formation, usage, adaptation and maintenance of subsets of sensors collaborating on specific tasks. VSN concept also promises to enhance applications that involve dynamically varying subsets of sensor nodes collaborating tightly to achieve the desired outcomes, while relying on the remaining nodes to achieve connectivity and overcome the deployment and resource constraints. This article explores the concept, mechanisms, and benefits of using VSN. Examples of VSN support functionality include support for nodes to join and leave VSNs, broadcast within a VSN, and merging of VSNs. VSNs will simplify application deployment, enhance performance and scalability, facilitate resource sharing, and provide a degree of physical topology independence in wireless sensor networks. Deployment of overlapping sensor networks aimed at different tasks, especially in harsh environments, will also significantly benefit when organized as VSNs over a shared infrastructure © 2007 IEEE.

We consider the problem of designing the distribution rule used to share "welfare" (cost or revenue) among individually strategic agents. There are many distribution rules known to guarantee the existence of a (pure Nash) equilibrium in this setting, e.g., the Shapley value and its weighted variants;however a characterization of the space of distribution rules that yield the existence of a Nash equilibrium is unknown. Our work provides a step towards such a characterization. We prove that when the welfare function is strictly submodular, a budget-balanced distribution rule guarantees equilibrium existence for all games (i.e., all possible sets of resources, agent action sets, etc.) if and only if it is a weighted Shapley value. © 2011 INRIA.

This paper presents a novel game to teach metabolism and enzymatic activity concepts, exploring game-based and active learning. This study is part of a larger project that aims to update primary and secondary school teachers with scientific knowledge, allowing them to include novel teaching strategies and general discussions about eating habits and health with their students. The game impact was measured by qualitative assessment of 75 teachers who used the game, and overall, the feedback was very positive. Enzigame has been developed to explore essential concepts of metabolism and enzymatic activity. A heterogeneous group of people from computing and biomedical science participated in creating the game's software, and another group worked on reviewing the pedagogic issues in the game to make it able to be used in the classroom. The computing subgroup created a game design document describing the game's features, mechanics, elements, and scenarios. The game's development was cyclic, constantly reviewing the requirements for pedagogic, content, and computing technical aspects. Our results show the strong game's evolution, which was possible through the constant feedback from teachers from middle school, high school, and university education. Now, we have Enzigame's stable final version, with several mechanics that approach the contents in a playful and didactic way. Enzigame teaches about metabolism and enzymes, and, at the same time, it tests the motor and reasoning player's capacity through its gameplay, where the player controls an enzyme and needs to lead that one to its substrates, regulating the body's metabolism. The gameplay is accompanied by the 'Teacher' character, who appears occasionally and explains things to the player, like an enzyme and how it works. The game has different levels, representing distinct places of the body. Such levels allow us to explore the various kinds of enzymes and the different phases of our metabolism.

This study explores how a game can be an effective active learning methodology for promoting health education and healthy eating habits among young students. The primary objective of the research was to develop an educational game that emphasizes the importance of healthy behaviors. To achieve this, the team created a game design document that described the game's main features, including themes, game mechanics, characters, scenarios, challenges, and feedback. The team used the Unity platform, a game development tool, to develop the game to create a unique game that engages young students in healthy activities. The game's educational content is reinforced through math.matical simulations that give players feedback about healthy choices, such as healthy eating and regular exercise. The feedback system aims to highlight the significance of healthy habits for overall health, even when the results of these habits may not be immediately visible. The team collaborated with health and nutrition experts to ensure the game's educational content was accurate and up-to-date. Experts validated the game to ensure its quality and effectiveness, while teachers tested its usability to identify any issues that could affect its use in the classroom. As a result of the research, the team developed an educational simulation tool primarily aimed at slightly older students. The game demonstrates the impact of good habits, breaking the problem of delayed gratification that affects young people. The game development methodology presented in this study can be a helpful model for educators and developers working in educational technology. The game's potential as an educational tool and its success in fostering healthy behaviors must encourage further research and development. In conclusion, an educational game emphasizing the importance of healthy behaviors can promote health education among young students.

Game-based learning has gained popularity in recent years, as it is an effective method to engage students and improve their learning experience. The present study aimed to investigate the use of game-based learning in teaching eating habits and health to elementary school students, focusing on nutrition and obesity. The study was part of a larger project to update elementary and high school teachers in Brazil on metabolism and obesity, linked to the World Health Organization (WHO) campaign entitled Beat Diabetes. Our research can be split into three methodological stages. In the first stage, we established the requirements for the topics covered in the game through meetings with experts in metabolism and obesity. The digital game was developed in the second stage using the Unity Engine and the C# language. The game was titled Food Battle and was inspired by another popular game called Plants vs. Zombies. In this game, the players had to choose healthy and unhealthy food options while fighting off junk food monsters. The third and final stage of the study was responsible for the verification, validation, and testing (VV&T) of the game. Programmers, computers, and medical teachers initially tested the Food Battle game. Then, the game was validated by its end-users, which included elementary and high school teachers and undergraduate students in biomedical sciences. The study's results showed a positive acceptance of the game as a teaching tool. The Food Battle game was playful, engaging, and effective in reaching various age groups of students. The use of games in education can offer various benefits to students, including increased motivation, engagement, and interest in the topic being taught. Additionally, games can assist teachers in the classroom by providing them with a tool that facilitates teaching complex issues such as obesity and healthy eating. The present study highlights the importance and benefits of games in education and how they can effectively impr
