During this stage, defects such as missing, floating, and disconnected objects may arise. Failure to detect these can lead to product malfunctions, crashes, or inoperability. This work highlights challenges in a real manufacturing environment, specifically during the validation phase of consumer electronic production. Addressing these issues is crucial and useful, as similar defects can occur in similar consumer electronics manufacturing settings. In this work, we present a solution that integrated a multi-class classifier trained to detect missing and disconnected objects which achieves an average accuracy of 99%.SPIE DIGITAL LIBRARYhttps://spie.org/optics-photonics/presentation/Validation-and-classification-of-assembly-defects-in-consumer-electronic-motherboards/13606-4
Diversidades en contextos de movilidad desde la perspectiva docente
Full text linkSe reporta un estudio sobre la diversidad del alumnado de educación básica en entornos de movilidad. Se utilizó una metodología mixta que combinó la aplicación de un cuestionario a 147 cuidadores y entrevistas a 33 docentes y equipo de apoyo, de siete escuelas primarias de Tijuana y Mexicali. Los resultados confirman una alta migración interna, donde 40 % tiene menos de cinco años viviendo en el estado, en su mayoría con intenciones de radicar de manera permanente. Se analizaron las perspectivas docentes en torno a la atención que se brinda al alumnado, destacándose que el profesorado ha desarrollado estrategias para trabajar en contextos educativos social, cultural y lingüísticamente complejos, estableciendo pautas para promover la inclusión educativa desde su práctica. No obstante, las escuelas desarrollan acciones para atender a la población migrante, afrontan desafíos en la formación docente, recursos de apoyo y compromiso hacia su escolarización.
Business ethics, corporate social responsibility, business training and innovative behavior as predictors of employee happiness
No full textPág. 25This research analyzes the impact of personal and social ethics, business training, corporate social responsibility and innovative behavior on happiness at work and personal happiness, with the aim of exploring how these interrelated variables affect work well-being. and its extension to the personal sphere. Coming from 97 academic studies by different authors, the analysis of the study variables was carried out and their relationships were found, creating the theoretical framework. The study is based on a sample of 323 employees, all of them university graduates, who work in the industrial and organizational sector. Quantitative approach. Thefirst hypothesis (H1), which proposed a positive relationship between personal ethics and happiness at work, was confirmed. The second hypothesis (H2), which proposed a positive relationship between social ethics and happiness at work, was not supported by the data. The third hypothesis (H3), which proposed a positive relationship between innovative behavior and happiness at work, was rejected. The fourth hypothesis (H4), which proposed a positive relationship between business training and happiness at work, was confirmed. The fifth hypothesis (H5), which proposed a positive relationship between social responsibility and happiness at work, was confirmed. The sixth hypothesis (H6), which postulated a positive relationship between happiness at work and personal happiness, was the most robust of all. Organizationsthat invest in the ethical and professional growth of their workers not only improve happiness at work, but also the overall happiness of their employees.

Effect of psychosocial factors on happiness at word in Mexico
No full textPág. 31In the post-pandemic context, markets face mental health challenges that should not be
underestimated. The Great Resignation was the result of employees reevaluating their
expectations regarding working conditions, the importance of work-life balance, and concerns
about stress or mental burnout. In this regard, the lack of emotional support and a work
environment that did not promote happiness or well-being led many to seek better options. This
phenomenon has reflected how people have prioritized their well-being and happiness at work,
seeking work environments that align more closely with their quality-of-life expectations.
Organizations in Mexico are also experiencing the serious consequences of this situation through
decreased productivity, increased absenteeism, and a noticeable decline in employee job
satisfaction. Psychosocial factors in the workplace, such as job stress, anxiety, and burnout, play
a decisive role in employees' subjective well-being and, consequently, in their motivation to
contribute to the development of their workplaces. Under these assumptions, the objective of this
study was to analyze the effect of psychosocial factors on happiness at work and how it impacts
turnover intention and organizational commitment. To achieve this goal, a quantitative study was
conducted using a closed-ended questionnaire applied during the second quarter of 2024 to 320
employees from various sectors in Mexico. The data were analyzed using structural equation
modeling (SEM) to examine the causal relationships between the study variables. Preliminary
results suggest that negative psychosocial factors, such as stress, anxiety, and burnout, have a
significant negative relationship with happiness at work, indicating that the higher the level of
these factors, the lower the employees' perceived well-being. It is important to highlight that
employee who reported high levels of happiness at work showed a lower intention to leave and
greater organizational commitment, suggesting that improving psychosocial conditions in the
workplace could contribute to talent retention and increased organizational productivity. The
study's results underscore the importance of addressing psychosocial factors that affect happiness
at work in Mexican companies. Organizations should implement strategies to reduce stress and
burnout, promoting wellness policies and emotional support. A work environment that values
work-life balance and offers flexibility becomes a key tool for improving job satisfaction,
reducing employee turnover, and ultimately increasing productivity.https://doi.org/10.24310/mumaedmumaed.22

Full text linkIn this work, a new series of carboxyl-functionalized bis(carbamoylcarboxylic) acid ligands (bCCAs) was synthesized to evaluate their performance as coagulant-flocculant agents. The interaction of these ligands with metal
ions was evaluated in solution by UV-Vis spectroscopy in organic media finding 1:2 and 1:1 (metal:ligand)
complexes. Zeta potential (pZ) analysis demonstrate the negative charge of these ligands at low pH, as well as the
charge neutrality adding metal ions reaching the isoelectric point (IEP) due to the complexation in aqueous
media. The Log Ka values (2.517 to 3.887) indicate a strong metal-ligand interaction in water. These new bCCAs
demonstrate outstanding performance in the simultaneous removal of metal ions such as Ca2+, Cd2+, Cu2+, Ni2+,
Pb2+ and Zn2+, acting as both coagulant and flocculants in a coagulation-flocculation process, and showing
excellent removal capacities (308 to 533 mg Mn+/g of L or 1.94 to 3.68 mol Mn+/mol of L), clarification kinetics
(48.6 to 136.8 T%/h) and sedimentation ratios (96 to 156 mm/h). Comparing with the bCCAs type ligands
previously studied, these carboxyl-functionalized analogues perform the fastest coagulation-flocculation process.
These results indicate a high potential for effectively removing metal ions from industrial wastewaterElsevierhttps://www.sciencedirect.com/science/article/abs/pii/S002228602500792

No full textThe classic Sudoku is a puzzle with simple rules that can become complicated to solve automatically due to the exponential increase in possible solutions as the board size increases. This paper presents an algorithmic solution to solve any size Sudoku incorporating an implementation in CUDA C/C++ that, consequently, leverages parallel programming on a GPU. This involves using threads and processes with shared and distributed memory for various solution strategies. These solution strategies encompass backtracking, where multiple alternatives are tried until reaching a solution, and rule-based algorithms that rely on heuristics to solve Sudokus, among others. Regardless of the implementation approach, it is pertinent to conduct a comparison between the solution achieved with a parallel algorithm utilizing a GPU and a sequential algorithm processed on the CPU. This is done to quantify the performance of the solution. The proposed algorithm managed to accelerate the traditional backtracking approach by up to 7x on a typical 9x9 Sudoku. While getting 7x and 3x reduction on 16x16 and 25x25 boards respectively.Revista Aristahttp://revistaaristas.tij.uabc.mx/index.php/revista_aristas/article/view/41

Full text linkAbstract: This article begins by examining the health dimension of forced migration, emphasizing challenges such as malnutrition, chronic stress, limited healthcare access, and heightened exposure to infectious diseases. To this end, a review of key theoretical approaches to human mobility was conducted, along with an analysis of emigration data and a general characterization of the border region. Applied analysis methods, including demographic health data and qualitative interviews, were used to capture both social and clinical aspects of the displacement experience. Subsequently, a qualitative analysis of border-crossing experiences was carried out, identifying emotional, physical, and economic impacts. This study highlights how forced migration generates not only social disruption but also
measurable health risks, underscoring the need for integrated bioanalytical, clinical, and public health interventions. The findings carry important implications for health
professionals, planners, and bioanalytical scientists seeking to design evidence-based responses to displacement.JOURNAL OF APPLIED BIOANALYSIShttps://journalofappliedbioanalysis.com/forced-migration-and-health-challenges:-bioanalytical-and-developmental-perspectives-from-the-northern-borde
Quantum Communications and Quantum Imaging XXIII
No full textCurrently, quantum algorithm developments are growing, and it is becoming essential to determine how efficient and feasible a quantum algorithm is. Although there is continuous development of quantum hardware, it is important to remember that we are still in the NISQ (Noisy Intermediate-Scale Quantum) era, which limits accessibility to this technology and imposes restrictions on time and the number of qubits. Furthermore, the coexistence of multiple computing paradigms and quantum architectures can lead to ambiguities when proposing quantum algorithms, making it essential to analyze their complexity. The adiabatic quantum computing (AQC) model and the quantum gate (QG) model, being the most widely used models, were considered in this study. The first approach to analyzing quantum algorithmic complexity involves counting the number of quantum gates employed by the algorithm in the QG model. However, the measurement of quantum algorithmic complexity extends beyond the QG framework. This gate-counting metric does not apply to the AQC paradigm, since adiabatic algorithms rely on continuous Hamiltonian evolution rather than discrete quantum gates. The purpose of this study is to explore the theoretical developments concerning quantum complexity, based on the approach presented in 1997 by Bernstein and Vazirani and the demonstration of the equivalence between the QG and AQC models presented in 2004 by Aharonov et al. As a result of this research, our proposal is illustrated using Grover’s search algorithm and Deutsch’s algorithm. Finally, a method is presented to measure the complexity of a quantum algorithm in an approximate manner, which enables us to visualize its scope while disregarding the influence that the chosen quantum model may have. Likewise, it is emphasized that the algorithm’s objective will be crucial when analyzing its complexity.SPIE DIGITAL LIBRARYhttps://www.spiedigitallibrary.org/conference-proceedings-of-spie/13618/3065844/How-to-measure-a-quantum-algorithm-complexities-and-models/10.1117/12.3065844.shor

No full textThis study presents a neuropsychological evaluation of a unique case of prosopagnosia (patient EP) with atypical lesion patterns, characterized by intact face-selective nodes but significant damage to the Vertical Occipital Fasciculus (VOF). Given the presumed interruption of ventral-parietal connectivity, we focused on assessing the potential presence of simultanagnosia and its potential relationship to his face recognition deficits. Our neuropsychological battery included tests of global and local processing, scene perception, and face recognition. Results revealed intact global processing abilities and no evidence of simultanagnosia, despite the patient’s prosopagnosia. These findings suggest that EP’s face recognition impairment is likely attributable to disrupted connectivity within the face processing network rather than a general deficit in global/holistic processing. This case highlights the importance of comprehensive neuropsychological assessments in atypical presentations of prosopagnosia and contributes to our understanding of the complex relationship between white matter integrity and face recognition abilities.Taylor & Francishttps://www.tandfonline.com/doi/full/10.1080/13554794.2025.248992
