This work investigates win prediction in professional Counter-Strike 2 matches using only information available before each match begins. Each observation is represented by differences between the two teams, computed from recent statistics, performance indicators and a pre-match strength measure. The task is framed as binary classification, with the aim of estimating the win probability of the analyzed team. The methodology separates training, selection and evaluation in temporal order: older matches are used for training and internal selection, while the 2026_s1 window is reserved as a later-period holdout evaluation. The experimental evaluation started from 38 pre-match attributes and registered 71 feature sets, 58 possible classifier configurations and 2,582 combinations actually evaluated. The selected solution is an L2-regularized logistic regression with C = 0.3, no artificial class balancing and 11 variables chosen by a univariate selection criterion. On the holdout set, this logistic regression achieved ROC-AUC of 0.6828 and an accuracy of 0.6293. The prospective evaluation over later events was kept as complementary evidence from operational use, without changing the selected model. The contribution is a reproducible workflow for pre-match prediction in Counter-Strike 2, connecting data, variables, training, classifier comparison, interpretation and complementary validation.

Public health increasingly relies on the responsible use of data to support hospital management. In this context, ensemble machine learning models achieve strong predictive performance but often operate as "black boxes," hindering their adoption in sensitive domains. This study investigates the application of Explainable Artificial Intelligence (XAI) techniques — specifically SHAP and LIME — to tree-based ensemble models (Random Forest, Gradient Boosting, and XGBoost). These models were applied to microdata from the Brazilian Unified Health System (SUS) Hospital Information System regarding hospital admissions in the state of São Paulo between 2024 and 2025. Models were developed to classify hospital length-of-stay ranges and to predict the number of days of hospitalization (regression) — evaluated using metrics appropriate for each task — as well as a model to classify cost ranges. The results indicate that the primary diagnosis, procedure, hospital type, municipality of residence, and secondary diagnosis are the most influential factors in the predictions, showing strong agreement between global (SHAP) and local (LIME) analyses. The study demonstrates how open government datasets can be transparently leveraged through modern computational methods, valuing both model performance and an understanding of the factors influencing their predictions.

This study presents a comparative analysis between the shear strength equation included in the proposed revision of the ABNT standard for structural masonry and the methodology currently prescribed by NBR 16868:2020. The study evaluated 147 walls, including a parametric analysis of a generic wall subjected to varying conditions regarding grouting ratio, vertical reinforcement layout, block strength, mortar strength, and pre-compression level. Additionally, walls from three actual structural masonry buildings—provided by a structural design firm—were analyzed. To simplify the comparative analyses, fixed parameters were adopted for certain variables. The results indicated that the NBR 16868:2020 methodology tends, in several instances, to yield higher shear strength values than those obtained via the proposed revision, particularly for walls with little or no grouting. It was found that explicitly accounting for the masonry's contribution, the pre-compression effect, the dowel action of the reinforcement, and the walls' geometric characteristics significantly influences shear strength. Thus, it is concluded that the proposed revision is more sensitive to the underlying resistance mechanisms, leading to more representative estimates of the structural behavior of masonry walls.

Requeijão is a traditional Brazilian processed cheese with significant economic and technological importance due to its widespread consumption and broad range of culinary applications. Its manufacture involves the fusion of curd obtained by acid or enzymatic coagulation, combined with ingredients that determine the product's texture, spreadability, stability, and sensory acceptance. This study aimed to compile and discuss information regarding the different types of requeijão, addressing aspects related to its classification, formulation, processing, rheological properties, quality control, microbiological and physicochemical analyses, as well as the current national and international market. A literature review was conducted based on scientific articles, books, technical documents, and official regulations, emphasizing recent publications and recognized sources in the field of Food Science and Technology. The review demonstrated that formulation composition, fat content, pH, emulsifying salts, processing conditions, and the fusion step directly influence the structural, rheological, and sensory properties of requeijão. Furthermore, the growing demand for reduced-fat, lactose-free, and innovative products has driven the development of new technologies and ingredients for this dairy product. It is concluded that understanding the factors involved in the production and technological properties of requeijão is essential for developing safe, high-quality, and technologically stable products, contributing to innovation and competitiveness in the dairy industry.

The objective of this study is to investigate the longevity of the careers of National Basketball Association (NBA) players who debuted between 2010 and 2020. A consolidated database for analysis was constructed using publicly available information on performance, individual characteristics, and injury history. Survival analysis methods were applied, initially with non-parametric estimates via Kaplan-Meier, followed by Cox proportional hazards models and extensions of the stratified model. The aim is to understand the factors that increase or decrease the length of time spent in the league, comparing groups of players by position, age at debut, minutes played, advanced statistics, and health history. Thus, the intention is to contribute to the literature on statistics applied to sport and to offer practical decision-making tools for professionals involved in sports management, scouting (the process of systematically observing and evaluating players), and performance analysis.

Food selectivity is a heterogeneous phenomenon characterized by persistent patterns of food refusal, a limited food repertoire, and/or repetitive consumption of a restricted range of foods, and may be associated with sensory, oral motor, behavioral, clinical, environmental, and sociocultural factors. Although food preferences are expected throughout development, food selectivity becomes clinically relevant when dietary restriction affects the variety and quantity of food consumed, participation in mealtimes, daily routines, family relationships, or eating autonomy. Objective – To describe, from the perspective of occupational therapists, therapeutic practices carried out in Brazil in the care of children and adolescents with food selectivity, considering assessment procedures, intervention strategies, family participation, documentation practices, and professional satisfaction. Method – This was a descriptive and exploratory study using a mixed-methods approach with a predominantly descriptive focus, conducted with 42 occupational therapists practicing in Brazil. Data were collected through an online questionnaire containing open- and closed-ended questions. Responses to closed-ended questions were analyzed using absolute and relative frequencies, without inferential purposes, while responses to open-ended questions were subjected to inductive thematic analysis. Results – The sample was predominantly from the Southeast region of Brazil (n=23; 54.8%) and included professionals with varying levels of experience. Services were provided mainly to preschool-aged children (n=30; 71.4%) and children aged 7 to 12 years (n=29; 69.0%), whereas no professional reported providing services to adults or individuals aged 60 years or older. Autism Spectrum Disorder was the clinical condition most frequently associated with food selectivity. During the initial assessment, the most frequently reported procedures were family interviews (n=42; 100%), standardized scales (n=36; 85.7%), clinical observation (n=34; 81.0%), and food diaries (n=27; 64.3%). Participants reported interventions involving Ayres Sensory Integration®, exposure and gradual approaches to foods, play-based activities, cooking activities, behavioral strategies, environmental adaptations, and caregiver participation. Among adolescents, interventions focused on autonomy, food choices, meal preparation, and participation in community settings. Most participants considered it possible to promote active participation in food-related decision-making (n=40; 95.2%). The most frequently reported methods for documenting progress were written reports (n=27; 64.3%), spreadsheets (n=11; 26.2%), and videos (n=8; 19.0%). Regarding professional satisfaction with working in the field of food selectivity, 32 participants (76.2%) reported being satisfied, 5 (11.9%) very satisfied, and 5 (11.9%) dissatisfied. Conclusion – The practices described indicate a multifactorial and contextualized approach, with strong family involvement and attention to sensory, behavioral, functional, and occupational components. The findings also reveal conceptual and methodological heterogeneity, reinforcing the need for greater diagnostic precision in distinguishing food selectivity from Avoidant/Restrictive Food Intake Disorder and Pediatric Feeding Disorder, as well as the need for specific assessment instruments, continuing professional education, and longitudinal studies to further investigate the effectiveness of interventions.

The city of São Paulo offers great opportunities, but it also exposes the deep inequalities faced by those living in its peripheries. In the district of Grajaú, in the far south of the capital, these opportunities coexist with daily hardships stemming from a historical process of occupation, expansion, and segregation, which still raises questions today about the future of its residents. In this context, young people's education is directly affected by instability in food security, housing, mobility, and safety, often losing priority in the face of the need to supplement family income, which contributes to school dropout rates. Given this scenario, the research investigates how young people from Grajaú manage to reach higher education, revealing trajectories marked by obstacles but also by the resilience of the territory, analyzed through the lens of Henri Lefebvre and his discussion of the production of urban space, with the aim of understanding the right to, access to, and persistence in higher education for these young people based on their own experiences and accounts.

Judith Butler's critique of the feminist notion of the subject, developed in the 1980s, resulted in the publication of Gender Trouble: Feminism and the Subversion of Identity (1990) and Bodies That Matter: On the Discursive Limits of “Sex” (1993). These works demonstrate an effort to problematize the very notions of the constitution of the subject and its bodily materiality, as these investigations sought to problematize gender. In this sense, the main objective of this work was to understand the genealogical method applied by Butler to analyze the conception of bodily materiality. The philosopher's critique is concerned with analyzing the mechanisms that operate in the materialization of gendered bodies, since when it comes to materiality, sexual difference is invariably invoked. Butler's reflections in these early works seek to conceive other possibilities for thinking about feminism without resorting to the category of "woman". The philosopher questions the restrictive identificatory bases of gender studies, and in this task, she uses and appropriates the genealogical method—of Nietzschean origin reformulated by Michel Foucault—to analyze gender ontologies and bodily materiality. Therefore, this research analyzes Butler's critical genealogy to expose the gendered materiality produced by the matrix of intelligibility, the result of a power that constitutes while simultaneously maintaining an excluded domain.

The creation of the São Paulo Criminal Asylum resulted from broader historical transformations in the administration of penal institutions. The challenge faced by the authorities was determining how to enforce a criminal sentence upon an individual who lacked the capacity to understand the unlawful nature of their actions. It is well established that individuals deemed insane were often held temporarily in prisons and police stations while awaiting transfer to psychiatric hospitals. This raises the question: what criteria did penal authorities use to request the transfer of detainees to psychiatric institutions? This study aims to examine how the establishment of a criminal asylum in São Paulo affected administrative practices and the movement of individuals between institutions. It argues that the development of administrative knowledge concerning institutions of confinement was more significant than the emergence of medical-criminological expertise regarding criminally insane individuals. A qualitative approach was employed to analyze the records of institutionalized detainees. The sources include the governor's messages to the state legislature and the proceedings of the Legislative Assembly concerning the creation of the São Paulo Criminal Asylum, which provide the historical context. The primary sources, however, consist of the medico-legal case files of institutionalized patients. Ten cases of incarcerated individuals transferred from state prisons to the São Paulo Criminal Asylum were selected for in-depth analysis.

Given the growing relevance of specific vulnerability classes—and the emerging techniques and paradigms for exploiting them—there is currently a lack of in-depth, detailed studies addressing these topics. Accordingly, this work aims to contribute to current system security research by examining the Use-After-Free (UAF) vulnerability class—which has consistently proven significant for discussing emerging exploitation techniques—through a case study involving the Linux kernel and a deliberately vulnerable module.

This work proposes a reflection on the self-publishing process, based on a personal experience, seeking to discuss how linguistic knowledge supports the relationship with writing. In view of a society constituted through graphic symbols, this research advocates writing beyond school and academic contexts and proposes to analyze an editorial object produced and published during undergraduate studies. The work reflects on the teaching methodology of Brazilian schools, defends writing as a therapeutic resource, and describes the process of constituting a book: from the idea to its execution. The work in question is the book “Eu Tenho Medo de Falhar”, published in digital format in September 2025 by an undergraduate student in Linguistics and author of the present work. The research is an experience report and, as such, is not based solely on a single theoretical framework. Ferdinand de Saussure, with the idea that linguistics is not limited to normative procedures, Paul-Michel Foucault, with the proposal of self-writing as a process of subjectivation, and contemporary theories on editorial design support our reflections.

Introduction: Adolescent idiopathic scoliosis (AIS) is a three-dimensional deformity of the spine characterized by lateral vertebral inclination in the frontal plane, rotation in the horizontal plane, and posterior flexion in the sagittal plane. This condition may lead to future health problems, such as low back pain and cardiorespiratory dysfunction. Screening programs are highly recommended and should be routinely incorporated into school-based physical examinations for early detection of the condition, with the aim of preventing or minimizing severe deformities. Objective: To estimate the prevalence of adolescent idiopathic scoliosis in São Carlos, São Paulo, Brazil. Materials and Methods: This was a cross-sectional observational study. Volunteers aged 10 to 18 years, of both sexes, enrolled in schools in São Carlos, São Paulo, Brazil, were recruited. Participants underwent postural assessment, including the Adams forward bend test combined with scoliometer measurement of the angle of trunk rotation (ATR), as well as spinal mobility tests and assessment of low back pain risk. Results: A total of 275 school students were evaluated, of whom 17 (6.2%) showed findings indicative of AIS (ATR ≥7°), while 26 (9.5%) were classified as suspected cases (ATR between 5° and 7°). A significant association was observed between findings indicative of AIS and classification as being at moderate/high risk for low back pain (p=0.0005), as well as reduced spinal mobility during right lateral flexion (p=0.0052). Conclusion: The prevalence of AIS observed among school students in São Carlos was 6.2%, with additional students identified as having findings suggestive of the condition. The association between findings indicative of AIS, a higher risk of low back pain, and reduced lateral spinal mobility reinforces the clinical relevance of these findings. Considering that postural changes during growth may negatively affect musculoskeletal function and quality of life, these findings reinforce the importance of early screening and follow-up in the school setting, which may facilitate identification, monitoring, and the implementation of preventive and therapeutic measures when necessary.

This work presents a first-principles investigation into the influence of stacking configuration on the structural, energetic, and optoelectronic properties of bilayer palladium dichalcogenides PdX2 (where X = S, Se, Te). The central objective is to analyze how different interlayer stacking patterns modulate the stability, electronic structure, and work function of these two-dimensional materials. The methodology employs computational simulations based on Density Functional Theory using the VASP software, describing the core-valence electron interactions via the projector augmented-wave method. The study uses the semilocal PBE functional for structural optimizations, obligatorily incorporating Grimme’s D3 correction for the rigorous treatment of van der Waals dispersion forces, which are fundamental elements for the stabilization of lamellar interfaces. For the refinement of the band structure and work functions, the research applies the HSE06 hybrid functional, ensuring greater accuracy in determining the band gap. The results indicate that the bulk-like configuration represents the global minimum energy state for the three investigated systems, serving as an absolute reference for stability. It is observed that the binding energy becomes progressively more negative in the sequence S → Se → Te, which reflects the increase in polarizability and the spatial extent of the electronic orbitals in the heavier atoms. The work demonstrates that PdS2 preserves its indirect band gap semiconductor character across all tested stackings, although the spatial organization significantly alters the electronic occupations near the band edges and induces a pronounced in-plane optical anisotropy for polarized light. In the PdSe2 system, stacking acts as a trigger for electronic phase transitions, allowing the material to transition between semiconductor, semimetallic, and metallic behaviors depending on the adopted geometry. Conversely, PdTe2 consistently maintains its metallic nature regardless of the stacking pattern, although it exhibits variations in the density of states and in the band crossings at the Fermi level. Bader charge analysis reveals that the stacking primarily perturbs the interfacial chalcogen atoms, establishing electric dipoles that shape the surface electrostatics. The work function exhibits a systematic reduction with the increase in chalcogen mass, but allows for additional fine-tuning through stacking engineering. The work concludes that the stacking configuration constitutes a practical and effective tuning parameter for the design of nanodevices. The detailed understanding of these mechanisms provides a theoretical foundation for the development of optoelectronic technologies and for contact engineering in two-dimensional materials.

This research seeks to understand how Thomas Hobbes's theological conceptions impact his political philosophy, highlighting the negative character of his statements about God and religious phenomena. His claims regarding divine incomprehensibility are present in his investigation of biblical revelation and the formation of religious dogmas, both of which are permeated by the dynamics of power — a key element in his anthropology. The purpose of this study is to examine how this apophatic position regarding the theological field as a whole determines the nature of sovereign right, as well as the role it plays in the secularization of political philosophy.

The prediction of the load-bearing capacity of four-pile concrete caps lacks normative consensus, as does the truss idealization in strut-and-tie models available in the literature, which are typically evaluated using small-scale models and square columns. A regression model results in an equation with terms calibrated from a database, a methodology already used in the literature for other structural elements to obtain load-bearing capacity values. Therefore, the objective of this study was to develop predictive equations, using regression models, as an alternative for determining the load-bearing capacity of four-pile caps based on their geometry. To this end, the study focused on compiling a database associated with numerical simulations. These numerical models were extrapolated from a calibration based on literature records, encompassing square and rectangular columns, as well as effective depths greater than those of the original experimental tests. From these data, nine equations with different variable interactions were developed, all showing R² values greater than 90%. It was observed that, for columns with a cross-sectional area of less than 50% of the total pile area, a dispersion in the predictions occurred across all equations due to the complex stress flow at the contact interface between the column and the pile cap. It was also found that the increase in load-bearing capacity associated with the elongation of one column dimension followed a quadratic function. Thus, despite the higher dispersion for area ratios below 50%, the regression models proved to be an effective and viable alternative. They bypass the truss idealization difficulties debated in literature and can be continuously refined by incorporating new experimental tests

Urban growth and the historical industrial occupation of several areas have contributed to the increasing occurrence of sites with contamination potential, making it necessary to develop studies that support their safe redevelopment. In this context, Preliminary Assessment represents the initial stage of Contaminated Site Management, allowing the identification of contamination indicators within the study area and supporting the planning of subsequent investigation stages. This study aimed to carry out the Preliminary Assessment of an area located in the municipality of Santo André, São Paulo State, Brazil, currently occupied by an educational institution and intended for future residential development. The methodology was developed according to the guidelines established by CETESB Directive Decision No. 038/2017/C. The results indicated that the site underwent different land uses over time, including activities with contamination potential, allowing the identification of potential contamination sources associated with past and current activities. Uncertainties related to the earliest periods of site occupation were also identified due to the lack of historical information. Based on these findings, the Conceptual Site Model was classified as MCA 1B, according to the classification system established by CETESB, due to uncertainties regarding the historical use of the site. Furthermore, the area was classified as a Suspected Contaminated Area, indicating the need for the continuation of the contaminated site management process through a Confirmatory Investigation. It is concluded that the Preliminary Assessment was essential for organizing the available information, identifying environmental uncertainties, and supporting decision-making regarding the management of the studied area.

Integrated photonics has established itself as an important technology for applications in optical communications, sensing, and signal processing, enabling device miniaturization and reduced energy consumption. In this context, efficient coupling between optical fibers and integrated waveguides is fundamental to the performance of photonic circuits. This work presents the design and optimization of SU-8 taper optical couplers, a low-cost polymer compatible with conventional microfabrication processes. Different transition geometries, polarization modes, and structural dimensions were analyzed with the aim of maximizing the coupling efficiency between optical fiber and waveguide. The results indicated efficiencies above 88% and losses below 0.6 dB for the best configurations, demonstrating the potential of SU-8 for applications in low-cost integrated photonic devices.

Autonomous navigation in indoor environments constitutes an important challenge in mobile robotics, especially in applications that require low computational cost, real-time operation, and the use of embedded platforms. In this context, monocular depth estimation emerges as a promising alternative to traditional depth sensors, as it allows spatial information to be inferred from a single RGB image. This work investigates the feasibility of using modern monocular depth models in autonomous navigation systems, focusing on the FastDepth model due to its computational efficiency and suitability for resource-constrained devices. To this end, a comparative evaluation was initially carried out between the FastDepth, MiDaS Small, and Depth Anything Small models, considering metrics such as number of parameters, model size, inference time, and computational cost. Then, FastDepth was integrated into a reactive controller implemented in the Webots simulator, with the aim of evaluating its performance in different indoor scenarios. The system was tested in three distinct environments: a large room, a narrow corridor, and a room with tables, representing increasing levels of spatial complexity. The results demonstrated that FastDepth presents excellent performance in processing time; however, its limitations related to relative depth and frame-to-frame instability hinder its application in denser and less structured environments. It is concluded that reactive monocular navigation is viable in controlled scenarios, but still requires complementary strategies to ensure greater robustness in real and varied environments.

This study aimed to analyze the contributions of initial teacher education in Pedagogy in preparing educators for pedagogical practice with students with Autism Spectrum Disorder (ASD). Grounded in the observation that initial teacher training still presents significant gaps in preparing educators to act within inclusive contexts, this research sought to identify the formative experiences, perceived challenges, and student suggestions to improve this process. The investigation adopted a qualitative, exploratory approach, utilizing an electronic questionnaire with open- and closed-ended questions administered to 49 undergraduate students at a Higher Education Institution in the State of São Paulo. Data analysis, conducted through content analysis, yielded eight thematic categories: “Academic profile and formative experiences”; “Initial training on ASD and Inclusive Education”; “Integration of theory and practice”; “Knowledge and use of pedagogical strategies”; “Conceptions of inclusion and schooling”; “Faced and perceived challenges”; “Feelings about teaching readiness”; and “Suggestions for teacher education.” The results indicated that, although inclusion is valued by future teachers, initial training still offers limited depth on ASD, demonstrates weak integration between theory and practice, and insufficiently addresses the affective and ethical dimensions of teaching. Furthermore, undergraduates reported feelings of insecurity and unpreparedness regarding the demands of inclusion, yet demonstrated a willingness for continuous learning and provided valuable suggestions for course enhancement. Recommended actions include strengthening the curriculum with dedicated courses, embedding inclusion cross-curricularly, encouraging practical workshops and interdisciplinary partnerships, and expanding experiences in real-world inclusive settings. It is concluded that ensuring initial teacher education aligned with the principles of equity and inclusion is an urgent and essential challenge for building democratic and humanizing schools. This study provides insights for discussions on teacher education policies and points toward pathways for future research in the field.

The expansion of Brazilian public higher education, combined with the implementation of affirmative action policies, has contributed to making universities more diverse and expanding access for historically underrepresented groups. Despite these advances, certain programs still exhibit low diversity, such as Mechanical Engineering, which has been historically characterized by the predominance of white men and by racial, gender, and socioeconomic inequalities. In this context, this study aims to analyze the profile of Mechanical Engineering students in Brazilian public institutions and discuss factors that may contribute to the low diversity observed in the program. To this end, a mixed-methods research approach was conducted, combining a qualitative literature review with a quantitative analysis of secondary data. The literature review addressed the historical development of engineering in Brazil, concepts related to diversity and inclusion, studies on racial and gender inequalities, and the experiences of LGBTQIA+ individuals in the academic environment. Additionally, microdata from the Higher Education Census provided by the Anísio Teixeira National Institute for Educational Studies and Research (INEP) for the period from 2020 to 2024 were analyzed. The results highlight progress in higher education access for minority groups, but also point to persistent inequalities in the profile of incoming and graduating students. In this regard, the importance of institutional initiatives aimed at promoting more inclusive and welcoming academic environments—aligned with the National Curriculum Guidelines and the demands of contemporary society—is discussed.
