This paper presents advancements in tracking features in high-speed videos of Caribbean steelpans illuminated by electronic speckle pattern interferometry, made possible by incorporating robust computer vision libraries for object detection and image segmentation, and cleaning of the training dataset. Besides increasing the accuracy of fringe counts by 10% or more compared to previous work, this paper introduces a segmentation-regression map for the entire drum surface yielding interference fringe counts comparable to those obtained via object detection. Once trained, this model can count fringes for musical instruments not part of the training set, including those with non-elliptical antinode shapes.

East Asians are more likely than North Americans to attend to visual scenes holistically, focusing on the relations between objects and their background rather than isolating components. This cultural difference in context sensitivity-greater attentional allocation to the background of an image or scene-has been attributed to socialization, yet it is unknown how early in development it appears, and whether it is moderated by social information. We employed eye-tracking to investigate context-sensitivity in 15-month-olds in Japan (n = 45) and the United States (n = 52).

A combined AFM/MS method was employed for protein registration in solution. This method is based on reversible specific capturing of a target protein from a large volume of analyzed solution onto a small sensor area of a chip with immobilized aptamer ligands. Fishing of the core antigen of hepatitis C virus (HCVcoreAg) from 10 M solution of this protein in buffer was carried out.

Although significant progress has been made in the effective measurement of Zn(II), Аlizarin red S (ARS) was immobilized on polyethylene polyamine-modified polyacrylonitrile (PPF-1) via a new matrix. This approach allows the detection of low levels of Zn(II) ions in various water samples via preconcentrated atomic absorption spectrometry. The use of PPF-1 in a polymer matrix for zinc preconcentration presents several advantages over traditional sorbtion-spectroscopic methods, including reduced cost, high zinc recovery, increased sensitivity, and selectivity.

Artificial intelligence-assisted imaging biosensors have attracted increasing attention due to their flexibility, allowing for the digital image analysis and quantification of biomarkers. While deep learning methods have led to advancements in biomarker identification, the diversity in the density and adherence of targets still poses a serious challenge. In this regard, we propose CellNet, a neural network model specifically designed for detecting dense targets.
