Volume 27 of the Journal of Inglomayor consolidates the journal’s open, community-oriented mission: to disseminate rigorous knowledge without financial barriers for readers. In a landscape where access to scholarly outputs is often constrained, this volume reaffirms a practical editorial conviction—scientific and technical work becomes socially useful when it is accessible, clearly written, and curated with methodological care.
This issue is intentionally interdisciplinary and bilingual. By explicitly tagging contributions in English [EN] and Spanish [ES], the volume supports both international visibility and regional knowledge transfer, strengthening the bridge between global scholarship and local educational needs. The resulting portfolio integrates mathematical and computational foundations, engineering-oriented modeling, health-science synthesis, and reflections on scientific publishing and the productive sector—particularly in contexts connected to natural resources and mining in South America.
The Articles section spans numerical analysis and applied modeling, including comparative perspectives on classical algorithms (e.g., Euler versus Runge–Kutta methods), practical geometrical modeling for engineering design, and data fitting through least-squares polynomial approximations. Complementing these methodological contributions, the volume includes a rigorous mathematical study of convergence in infinite series and an interdisciplinary review on determinants of precocious puberty, demonstrating how quantitative reasoning and integrative evidence synthesis can jointly inform both theory and practice.
In parallel, Volume 27 hosts reflections directly connected to societal relevance and the ethics of scholarship: a Spanish-language contribution on mineral-resource evaluation and the economic importance of mining; and a reflective piece on scientific publication across sciences and humanities, with particular attention to large-scale mining in Chile. Together, these works emphasize that scientific progress is inseparable from responsible communication, critical evaluation of evidence, and the capacity to translate results into decision-relevant knowledge.
The Report section centers on public policies, salt flats, and lithium extraction technologies, framing the energy transition in South America as a coupled scientific–technological–environmental–social agenda. This contribution aligns with the journal’s commitment to topics where engineering innovation, sustainability, and governance intersect—areas in which high-quality synthesis and clarity of assumptions are essential for constructive public debate.
Finally, the Text-Books section underscores a principle often underestimated in research dissemination: durable progress requires robust learning materials. Lecture notes and educational resources included in this volume (spanning fluid mechanics, solid-state fundamentals, general chemistry, and mining history) aim to strengthen training pathways and to support the formation of future professionals who can engage critically with both classical knowledge and emerging technologies.
Looking ahead, the journal will progressively expand its thematic scope in advanced artificial intelligence—next-generation deep learning, specialized transformer architectures, symbolic AI and hybrid neuro-symbolic systems, next-generation AutoML, advanced reinforcement learning, AI for science and technology (AI4Science), self-supervised and semi-supervised learning, causal AI, quantum computing and quantum machine learning, and advanced explainable AI (XAI). Volume 27 therefore functions both as a curated snapshot of present contributions and as a forward-facing platform that invites national and international experts to participate in future issues under a shared commitment to openness, rigor, and societal relevance.
