The New Era of Metrology: What Lies Ahead for National Metrology Institutes?

This article examines the strategic implications of the 28th General Conference on Weights and Measures (CGPM) for the future of National Metrology Institutes. It focuses particularly on the digital transformation of the global metrology system and explores how developments such...

Edge intelligence for automated off-grid structural triage in day-zero earthquake response

Post-earthquake structural damage assessment traditionally relies on manual visual inspections, creating critical bottlenecks during disaster response. To automate this process, this paper introduces ChilloRa, an end-to-end edge-to-GIS framework for rapid Day-Zero structural tria...

Development of novel dental composites integrated with MSN–TQ systems

Thymoquinone (TQ), recognized for its potent antibacterial capabilities, is a promising compound for both preventive and therapeutic applications in various diseases. In this study, TQ molecules were successfully loaded onto biocompatible, easily synthesized, and cost-effective M...

From Footprints to Fingerprints: Rethinking Orthographic Drawing via Sarkis

Sarkis Zabunyan's OPUS series consists of watercolor interpretations of the plans of architectural structures, built or unbuilt, selected from different times and places, in which the artist has a personal interest. This action, which Sarkis likens to the interpretation of a musi...

Predictive Line-of-Sight Geometry Compatibility in High-Rate GNSS: Formulation, Validity, and Causal Limits

High-rate Global Navigation Satellite System (GNSS) measurements can resolve dynamic motion, but detecting a spectral component does not identify its physical source. This study formulates Predictive Geometry-Normalized Structural Compatibility (PGNSC) as a post-detection, single...

Isolation of indigenous soil bacteria with potential application for diuron removal

Diuron is a widely used herbicide in sugarcane, cotton, coffee, and citrus production and is classified as a priority pollutant. Physical and chemical remediation of pesticide-contaminated sites is often technically complex and costly. Microorganism-mediated bioremediation offers...

The Dynamic Response Index: Non-intrusive extraction of proton exchange membrane fuel cell aging signatures from 1-Hz transients

Voltage loss is widely used to monitor proton exchange membrane fuel cell (PEMFC) aging, but it provides limited information during load-varying operation by combining irreversible degradation with reversible hydration, thermal, and recovery effects. To address this non-intrusive...

Exploring Dual-Defect-Mediated Mo–FeS2/Bi@BiOBr Heterojunction for Photocatalytic-Assisted Fenton Degradation of Cefixime Antibiotic

Abstract The photocatalytic-assisted Fenton mechanism has garnered considerable significance in cefixime (CFX) remediation. However, the fabrication of a photocatalyst with superior performance persists as a formidable challenge. Herein, a synergistic dual-modulation involving Mo...

Reticulated Ferrocene−Polycarbazole Nanofibers Coupled with CuAl-LDH for Ultrasensitive Label-Free Electrochemical Detection of CA125

Abstract The development of highly sensitive and reliable sensing platforms for ovarian cancer biomarkers is of considerable importance for improving the early diagnostic performance and supporting clinical decision-making. Cancer antigen 125 (CA125) is among the most critical tu...

Metrology and Quality Infrastructure: The Invisible Foundation of Advanced Technology

Metrology and quality infrastructure are rarely visible in public discussions, yet they form an essential foundation for scientific research, industrial production, healthcare, energy systems, international trade, and technological independence. This working paper examines how me...

Ligand Functionalization and Fe Precursor Selection Modulated the Physicochemical Properties of Fe-MOFs and Their Biological Response on Prostate Cancer and Normal Prostate Cells

Abstract Metal-organic frameworks (MOFs) offer modular platforms for cancer nanomedicine, but how metal precursor chemistry and linker functionalization jointly regulate physicochemical properties and biological response remains insufficiently defined. Here, three Fe-based MOFs,...

C-terminal–mediated modulation of Holin function from bacteriophage K: implications for phage-derived antimicrobial design

Among phage-derived antimicrobial molecules, holins are membrane-active proteins that play a central role in bacterial lysis; however, the contribution of their individual structural domains to antibacterial activity remains poorly understood. In this study, we investigated the f...

Photometric Investigation of the Unclassified Optical Transient AT 2026aaen: Discovery of a Low-Surface-Brightness Dwarf Host Galaxy

We report the comprehensive photometric characterization of the unclassified optical transient AT 2026aaen, discovered by the Zwicky Transient Facility (ZTF) on September 1, 2026 (MJD 61275.1). Deep spatial cross-matching using high-resolution archival data from the DESI Legacy I...

Air ticket sales forecasting for B2B travel agencies

Purpose This study addresses the air ticket sales forecasting problem for business-to-business (B2B) travel agencies, a largely unexplored area compared to airlines and business-to-consumer agencies. To meet guarantee deposit requirements and manage financial risk exposure, B2B a...

From Physics to Measurement, from Measurement to Health Technology, and from Health Technology to Social Benefit : A Country That Can Measure Is a Society That Can Improve

This publication explores the interdisciplinary pathway through which physics is transformed into reliable measurement, measurement enables the development and validation of health technologies, and health technologies generate economic and social value. Drawing on examples from...

To Measure Is to Exercise Sovereignty: The Impact of Metrology Infrastructure on Technological Sovereignty and the National Economy

This study examines the strategic role of metrology infrastructure and national measurement systems in technological sovereignty, economic development, and social welfare. It argues that the ability to manufacture advanced technologies is not sufficient on its own: countries must...

Comparative proteomic analysis of environmental and genetic models of Parkinson’s disease highlights the role of purine metabolism

Parkinson’s Disease (PD) is the second most common neurodegenerative disease, with many cases attributed to environmental exposures. Paraquat (PQ), is a pesticide and neurotoxicant strongly associated with increased PD risk. PQ is a weak inhibitor of complex I of the electron tra...
