Published: February 2023

When the traditional calibration methods of measurement instruments are applied, these measurement instruments need to be transmitted to a higher-level validation body for calibration. During transportation, many unknown factors will lead to additional errors that cannot be measured. Remote calibration effectively solves the problems of long calibration cycle and additional error generation. This Review summarizes research achievements made in the field of remote metrology. By comparing the existing remote calibration methods, their advantages and disadvantages are analyzed. Combined with the previous work of the research team, the application scenarios of the future remote value transmission and traceability technology are proposed.

The effectiveness of poultry vaccination in preventing the transmission of highly pathogenic avian influenza viruses (AIVs) has been debated, and its impact on wild birds remains uncertain. Here, we reconstruct the movements of H5 subtype AIV lineages among vaccinated poultry, unvaccinated poultry, and wild birds, worldwide, from 1996 to 2023. We find that there is a time lag in viral transmission among different host populations and that movements from wild birds to unvaccinated poultry were more frequent than those from wild birds to vaccinated poultry.

Ensuring the provision of safe drinking water necessitates thorough monitoring of microbial water quality. While traditional culture-based enumeration of bacterial indicators has served as the gold standard in compliance monitoring since the late 19th century, recent advancements in microbial sensor technology, driven by automation and digitalization, are revolutionizing on-site monitoring capabilities. These innovations offer unparalleled potential for automated, high temporal frequency monitoring with remote, real-time data transmission.
