Circular aperture areas are standards of high importance for the realization of photometric and radiometric measurements, where the accuracy of these measures is related to the accuracy of the circular aperture area calibrations.In Neurological Health order to attend the requirement for traceability was developed in Brazilian metrology institute, a
Background Hyperparathyroidism (HPT) is classified into primary HPT (PHPT), secondary HPT (SHPT), tertiary HPT (THPT), and pseudohyperparathyroidism.Parathyroid surgery is generally reserved for patients with symptomatic PHPT and asymptomatic USB Port patients who meet the surgical guideline criteria.However, the risk of complications and mortality
An external modulation laser module assembly (EMLMA) is proposed to suppress nonlinear errors in an interferometry system and improve its measurement performance.The EMLMA employs both phase Wall Stickers modulation with radio frequency signal and a specific modulation amplitude switching mode, enabling the suppression of noise introduced by spurio
