This study presents a dual-layer GraphRAG framework for petroleum engineering question answering, in which instance-level facts and domain-level concepts are explicitly separated and integrated into retrieval-augmented generation. To evaluate the framework, a benchmark of 40 expert-constructed Q&A pairs was developed, covering factual, definitional, and explanatory queries derived from a real offshore oilfield dataset. Results show that the dual-layer graph consistently outperforms a single-layer baseline. Answer accuracy improves from 0.65 to 0.70, faithfulness from 0.54 to 0.61, and context relevance from 0.69 to 0.72, confirming that the system retrieves factual parameters more reliably and provides conceptually grounded explanations. Gains in evidence recall and coverage are more modest, highlighting areas for further optimization. A case study illustrates the framework’s ability to expand petroleum terminology (e.g., “sandstone → clastic rock”), producing responses that are not only quantitatively more reliable but also qualitatively more informative. The dual-layer design effectively addresses the semantic consistency gap in petroleum QA, offering practical value for reservoir evaluation, lithology interpretation, and technical decision support. These findings demonstrate the potential of GraphRAG to enhance knowledge management and intelligent services in petroleum engineering. Full article

Audiovisual Entrainment (AVE) is a non-invasive, non-pharmacological neuromodulation approach that aims to align brain activity with externally delivered auditory and visual rhythms. This review surveys AVE’s historical development, technical parameters (e.g., frequency, phase, waveform, color, intensity, presentation mode), components and delivery methods, reported clinical applications, and safety considerations. Given the heterogeneity of AVE protocols and terminology, we conducted a structured narrative review (PubMed, Scopus, Google Scholar; earliest records to July 2025), including human and animal studies that met an operational definition of regulated AVE and consistent administration of specified auditory and visual frequencies, with critical methodological details reported. We highlight AVE’s accessibility and versatility, outline a stepwise parameter reporting framework to support standardization, and discuss putative mechanisms via sensory and oscillatory pathways. However, current findings are heterogeneous and include null or limited effects. Mechanistic understanding and parameter optimization remain insufficiently developed, and premature claims of efficacy are not warranted. Rigorous, standardized, and adequately controlled studies are needed before AVE can be considered a reliable therapeutic tool. Full article

The geophysical techniques ground penetrating radar (GPR) and electrical resistivity tomography (ERT) are commonly used data collection methodologies in numerous disciplines, including archaeology. Many researchers are now, or will be in the future, associated with projects that use these geophysical techniques, but who are not well versed in the instrumentation, its function, related terminology, data interpretation, and outcomes. This entry outlines the general approach and background for completing this type of research, dissects the methodology from a completed geoarchaeological project that uses both GPR and ERT, and provides concise definitions and explanations for all facets of the methodology. Based on this methodology, 21 terms or concepts related to GPR are explained in detail, as are 26 terms or concepts related to ERT, and visual representations of some of the terms and concepts are further illuminated via 11 figures. There are also 133 references linked to the various concepts and terms presented in this entry. Full article

The widespread adoption of Artificial Intelligence (AI) in critical domains, such as healthcare, finance, law, and autonomous systems, has brought unprecedented societal benefits. Its black-box (sub-symbolic) nature allows AI to compute prediction without explaining the rationale to the end user, resulting in lack of transparency between human and machine. Concerns are growing over the opacity of such complex AI models, particularly deep learning architectures. To address this concern, explainability is of paramount importance, which has triggered the emergence of Explainable Artificial Intelligence (XAI) as a vital research area. XAI is aimed at enhancing transparency, trust, and accountability of AI models. This survey presents a comprehensive overview of XAI from the dual perspectives of challenges and opportunities. We analyze the foundational concepts, definitions, terminologies, and taxonomy of XAI methods. We then review several application domains of XAI. Special attention is given to various challenges of XAI, such as no universal definition, trade-off between accuracy and interpretability, and lack of standardized evaluation metrics. We conclude by outlining the future research directions of human-centric design, interactive explanation, and standardized evaluation frameworks. This survey serves as a resource for researchers, practitioners, and policymakers to navigate the evolving landscape of interpretable and responsible AI. Full article

This paper provides an overview of key methods for assessing the quality of measurement systems and measurement results. Fundamental concepts are analyzed and their definitions compared across various metrological standards. Particular emphasis is placed on the issue of terminological inconsistency, as the same terms are interpreted differently in different documents, which may lead to misinterpretation or incorrect application of methods. This paper also presents practical examples of how these methods are applied to real data. Clear indications are provided regarding the conditions under which each method is recommended, depending on factors such as model complexity, data availability, and intended application. In addition, it offers a discussion and recommendations for future directions, highlighting the need for harmonized terminology, standardization of evaluation procedures, and the adoption of advanced technologies such as artificial intelligence and machine learning in the assessment of measurement quality.

Despite the growing adoption of modular construction (MC) to enhance productivity, sustainability and industrialization in the building sector, critical terminological inconsistencies and conceptual ambiguities persist across academic, professional and regulatory domains. This study conducts a systematic literature review to investigate how the key terms modular, module, modularity, modularization and modular coordination are defined and applied in the recent literature. Following the PRISMA protocol, 85 peer-reviewed articles were selected from an initial pool of 4832 Scopus records. Bibliometric and thematic analyses reveal a lack of conceptual consistency in the application of key terms, most notably the frequent misuse of module to describe non-volumetric components. Beyond identifying these ambiguities, this study maps the most recurrent definitional patterns to outline potential pathways toward conceptual consensus. It clarifies the boundaries between modular (a system attribute), modularization (a design strategy), modularity (a system property), module (a prefabricated, spatially autonomous, functionally complete, and volumetric unit) and modular coordination (a dimensional grid system). Based on these insights, it proposes a conceptual hierarchy, and a set of propositions integrated into a structured glossary that contribute to terminological clarity, foster standardization, and improve communication in the Architecture, Engineering, and Construction (AEC) sector.

Background: Vanishing twin syndrome (VTS) represents a complex and under-recognized phenomenon in multifetal pregnancies, associated with both clinical uncertainty and significant psychosocial impact. Despite its frequency, gaps remain in diagnostic clarity, international guidelines, and communication strategies with patients and families. Materials and Methods: This hybrid review integrates narrative and systematic elements to assess the diagnostic, clinical, and psychosocial gaps in VTS. A systematic literature search was conducted across Medline/PubMed, CINAHL, PsycINFO, EBM Reviews, and Scopus using terms such as “vanishing twin syndrome,” “patient-provider communicat*,” and “bereave* care.” Sources included systematic reviews, randomized controlled trials, cohort studies, and qualitative studies. Exclusion criteria were outdated publications (>10 years old). Results: Evidence revealed multiple domains of concern. Clinical risks and diagnostics remain poorly defined, with inconsistent recognition of maternal and neonatal complications. Psychosocial impacts were prominent, encompassing grief, identity disruption, and unmet support needs. Patient–provider communication was frequently inadequate, with insufficient training and lack of standardized language. International guidelines varied widely in scope, with only a few of them providing clear recommendations for bereavement care in multifetal loss contexts. Discussion: Emerging discourse highlights the limitations of the traditional fission model and alternative conceptual frameworks, such as Herranz’s model, for understanding VTS. These theoretical differences underscore the need for precise terminology and consistent diagnostic practices. Clinical implications extend to prenatal screening, obstetric management, and the integration of psychosocial support. Patient-centered communication and structured support initiatives (e.g., the Butterfly Project) demonstrate the potential to bridge communication gaps and improve care experiences. Conclusions: VTS requires recognition as both a medical and psychosocial condition. Improved clinical definitions, harmonized international guidelines, and emphasis on empathetic communication are essential to address the current gaps. Integrating these elements into practice may enhance patient outcomes and provide families with validation and support following multifetal loss. Full article

Progress in clinical practice, research, and teaching needs a common language. Agreement among veterinary endocrinologists on definitions of concepts related to Cushing’s syndrome (CS) and hypoadrenocorticism is lacking. After a successful inaugural cycle on diabetes mellitus terminology, project Agreeing Language in Veterinary Endocrinology (ALIVE) held a second cycle, with simplified methodology, and brought together 10 experts of the European Society of Veterinary Endocrinology (ESVE) and the Society of Comparative Endocrinology (SCE). It employed a four-round modified Delphi Method to generate draft definitions and try and achieve consensus. A final round used an endorsement survey of the expert-generated definitions distributed to the ESVE and SCE memberships, seeking a simple majority endorsement. A minimum of 20% membership participation was sought. The 10 experts achieved 100% consensus on the definition of 35 adrenal disease-associated concepts, including disease definitions, diagnostic criteria, and test definitions, a disease classification system for CS and hypoadrenocorticism, and a clinical scoring system for CS. Definitions were subsequently assessed by 78 ESVE and SCE members (26% of combined memberships). All definitions achieved a simple majority, ranging from 83.1 to 100%. ALIVE proved effective in creating a body of terminology for adrenal disease in companion animals, which met the overall approval of a majority of those participating in the endorsement phase. The prospective use of these definitions could help improve comparability and standards for adrenal disease research, education, and clinics. Full article

Background and Rationale: Visceral disorders, both functional and organic, significantly impact health-related quality of life and pose a challenge for healthcare systems. Osteopathy offers manual, systemic, and patient-centered approaches for their management, yet these remain controversial due to limited scientific support and methodological inconsistencies. In the evolving landscape of healthcare regulation in Europe, and particularly in Italy, exploring clinical reasoning and operational models in visceral osteopathy is essential. This study aimed to explore the beliefs, clinical reasoning, and management strategies of experienced Italian osteopaths in the treatment of visceral disorders using a Constructivist Grounded Theory approach. Methods: This qualitative study applied a Constructivist Grounded Theory approach to explore the beliefs and clinical practices of 10 experienced Italian osteopaths. Semi-structured interviews were transcribed, coded, and thematically analyzed, integrating literature comparisons to support theory generation. Results: Four core themes emerged: (1) education and professional development, (2) definition and identification of visceral disorders, (3) clinical management strategies, and (4) multidisciplinary collaboration. The findings reveal marked heterogeneity in diagnostic frameworks and treatment rationales, often driven by tradition and subjective interpretation rather than empirical evidence. Palpatory assessments were frequently prioritized over patient-reported outcomes. Conclusion: The study highlights substantial fragmentation in Italian visceral osteopathic practice, echoing challenges across Europe. Promoting a shift towards critical thinking, evidence-based models, shared terminology, and interprofessional integration is essential for contextualising osteopathic contributions to the care of individuals presenting with visceral-related problems. These findings provide insights into the fragmented clinical practices of Italian osteopaths and may contribute to shaping a more critical and evidence-informed approach within Italian osteopathic practice and professional development, which is now more relevant than ever, given the recent integration of osteopathy into the Italian higher education system.

Malaysia has committed to phasing out single-use plastics as part of its national sustainability agenda; however, the specific regulatory guidelines for implementing biodegradable and compostable bioplastics remain underdeveloped. This study aims to formulate practical and scalable guidelines for biodegradable and compostable bioplastic products, with a focus on the Federal Territory of Kuala Lumpur as a pilot case. Using a stakeholder-driven approach, a series of focus group discussions (FGDs) was conducted with key representatives from government bodies and the bioplastics industry. The guideline development process encompassed the identification and standardisation of terminology, definition of scope, certification frameworks, regulatory alignment, implementation strategies, and compliance mechanisms. The findings reveal a consensus among stakeholders on the need for clear and harmonised definitions to prevent ambiguity, as well as for certification protocols and enforcement mechanisms to align with existing legal frameworks. Revisions were proposed to terms, scope, and timelines to ensure legal compatibility and practical enforceability. The proposed guideline framework offers substantial potential for national adoption, contingent on inclusive stakeholder engagement across all Malaysian states to ensure uniformity and contextual relevance in its implementation. This study advances Malaysia’s SDG commitments by promoting sustainable bioplastics guidelines, encouraging national adoption through stakeholder engagement, and emphasising future integration of the life cycle assessment (LCA) to enhance the policy’s impact.

This study examines the diversity of terminologies associated with assistive technology (AT), a crucial field that promotes autonomy and inclusion for people with disabilities. Although the wide use of assistive technology is observed in the literature, a variety of terms are often used interchangeably, which hinders research, technological development, and the formulation of public policies. In this sense, this systematic review aimed to identify, categorise, and analyse the diversity of terms used to describe AT in the scientific literature, contributing to greater conceptual clarity and supporting structured and interdisciplinary development in the field. A comprehensive search was conducted in July 2024 across the Scopus, Web of Science, and PubMed databases, covering publications from 1989 to 2024. Eligible studies were peer-reviewed journal articles in English that conceptually defined at least one AT-related term. The selection process followed the PRISMA 2020 guidelines and included studies from Q1 and Q2 journals to ensure academic rigour. A total of 117 studies were included out of 11,941 initial records. Sixteen distinct terms were identified and grouped into five clusters based on semantic and functional similarities: Cluster 1—Technologies for assistance and inclusion. Cluster 2—Functional assistive devices. Cluster 3—Assistive interaction interfaces. Cluster 4—Assistive environmental technologies. Cluster 5—Assistive systems. A complementary meta-analysis revealed geographic and temporal trends, indicating that terms such as “assistive technology” and “assistive device” are globally dominant. In contrast, others, like “enabling technology,” are more context-specific and emerging. The findings contribute theoretically by providing a structured framework for understanding AT terminology and practically by supporting the design of public policy and interdisciplinary communication.

Modern heritage (MH) is a key component of our built environment; however, it currently lacks widespread recognition and a clear, universally accepted definition, placing it in an emerging phase. This category of heritage, understood within the context of modernisation processes and the changes characteristic of the late modern period, remains underrepresented and warrants further study. The objective of this article is to fill the identified research gap, thereby fostering awareness of MH, improving its accessibility and enhancing its visibility and appreciation. It offers a diagnostic analysis of the corpus on MH through the design and development of a concrete methodology, which is transferable to the other heritage categories. This study reveals insights into the present understanding of the term ‘Modern Heritage’ and its relevance within an international framework. This understanding prompts a reflection on the terminology used to describe this concept, which serves not only as a significant result in itself but also as a foundation for future research. Despite the close association of modern heritage with the 20th century, this research identifies a cross-cutting nature that needs to be recognised, encompassing a wide range of periods, themes and typologies in this category.

The lack of precise definitions in plastics-related terminology continues to hinder the development of coherent sustainability strategies across the materials value chain. This communication revisits current definitions of plastics, polymers, and bioplastics, distinguishing between source (bio-based vs. fossil-based), structure (synthetic vs. natural polymer), and degradation behaviour (persistent vs. compostable or biodegradable). It critiques ambiguous classifications promoted in policy and marketing discourse. It introduces the concept of “Zero-Trace Plastic” (ZTP) to refer to materials that are non-plastic substitutes intended for versatile plastic-like uses while guaranteeing no trace of synthetic plastics in their composition and no contribution to pollution across their lifecycle. The ZTPframework prioritises complete mineralisation without plastic or microplastics or chemical residues under real-world conditions. ZTP is proposed not as a replacement for existing biodegradability standards, but it helps distinguish between plastic and non-plastic biopolymers and works as a complementary benchmark for biodegradability that aligns with and extends them by incorporating environmental specificity and system-wide traceability. The paper proposes a harmonised terminology matrix and calls for coordinated efforts by international agencies and standardisation institutes, national bodies and industries to avoid using misleading terminologies like bioplastics, often used for greenwashing and to enhance circular material strategies.

Transparency is a key requirement for some classes of robots, exoskeletons, and assistive devices (READs), where safe and efficient human–robot interaction is crucial. Typical fields that require transparency are rehabilitation and industrial contexts. However, the definitions of transparency adopted in the literature are heterogeneous. It follows that there is a need to clarify, summarize, and assess how transparency is commonly defined and measured. Thus, the goal of this review is to systematically examine how transparency is conceptualized and evaluated across studies. To this end, we performed a structured search across three major scientific databases. After a thorough screening process, 20 out of 400 identified articles were further examined and included in this review. Despite being recognized as a desirable and essential characteristic of READs in many domains of application, our findings reveal that transparency is still inconsistently defined and evaluated, which limits comparability across studies and hinders the development of standardized evaluation frameworks. Indeed, our screening found significant heterogeneity in both terminology and evaluation methods. The majority of the studies used either a mechanical or a kinematic definition, mostly focusing on the intrinsic behavior of the device and frequently giving little attention to the device impact of the user and on the user’s perception. Furthermore, user-centered or physiological assessments could be examined further, since evaluation metrics are usually based on kinematic and robot mechanical metrics. Only a few studies have examined the underlying motor control strategies, using more in-depth methods such as muscle synergy analysis. These findings highlight the need for a shared taxonomy and a standardized framework for transparency evaluation. Such efforts would enable more reliable comparisons between studies and support the development of more effective and user-centered READs. Full article
