Objectives: The chemiluminescence immunoassay automated Abbott ARCHITECT hepatitis B surface antigen (HBsAg) screening assay is globally recognized for its superior sensitivity but notably low specificity. This mandates positive results confirmation by another confirmatory assay, such as the widely used Abbott ARCHITECT HBsAg neutralizing assay. This study aimed to evaluate the performance of the new chemiluminescence immunoassay, Mindray CL-900i HBsAg screening assay in comparison to the ARCHITECT neutralizing/confirmatory assay.

Gaps remain in surgical education regarding the representation of skin tone diversity. To improve equity and prevent misdiagnosis leading to worsened health outcomes, efforts must be made to ensure educational photographs are representative of the diverse patient populations plastic surgery residents will be treated in their future practices. Four study investigators examined 96 h of recorded lecture seminars from a Canadian plastic surgery resident education curriculum from May 2020 to December 2021.

Metamaterials hold great promise for application in the field of perfect absorbers due to their remarkable ability to manipulate electromagnetic waves. In this work, a full-spectrum ultra-wideband solar absorber with a multilayer metal-dielectric stacked structure is designed. Our absorber is simple and easy to manufacture, with Ti serving as the substrate, overlaid with SiN spacer layers and four pairs of Ti-SiN ring columns.

Utilizing the input-output formalism, we quantitatively relate the probability of correctly inferring the presence or absence of the object to the probability of avoiding absorption. We show that, if the cavity decay rate due to absorption by the object is comparable to that of the empty cavity and to the object-induced detuning, the product of the two probabilities is maximized by an undercoupled cavity, in which case detection in transmission is favorable to that in reflection.
View Article and Find Full Text PDFFiber-optic vibration sensors have been studied widely owing to their anti-electromagnetic interference, corrosion resistance, and ease of integration and distribution. Previous reports primarily focused on the frequency detection of vibration signals. However, the amplitude sensitivity, noise-equivalent amplitude (NEA), and stability determine the sensing precision and accuracy of the device.
