First, we will discuss how the size and complexity of the FSO encoder can be dramatically reduced using emerging nanophotonic structures. For a long time, all the FSO encoders are implemented in discrete macroscopic optics (e.g., lens, mirror,…

In each measurement, one of the analyzers was placed precisely at the reciprocal space locations where CDW signal has previously been reported^31,35,40. The rest of the analyzers of the array recorded IXS spectra at other reciprocal space…

Processing images from BCAT experiments

NASA’s PSI database contains plentiful information about the BCAT experiments⁵⁵. The four BCAT experiments conducted, BCAT-3, 4, 5, and 6, each consist of ten samples at room temperature, T = 295 K

This study involved using a dataset containing CT images, which were used to classify brain tumors into six different classes. The image dataset consisted of two main categories of brain tumors. Benign brain tumor: This category encompasses three…

All the prepared samples were subjected to X-ray diffraction (XRD) analysis, and the obtained XRD patterns are shown in Fig. 1a. There are two characteristic peaks of carbonaceous materials that can be seen in the XRD pattern. The first and most…

Surface polarity and heteroepitaxial relationships

The microstructural characteristics of the multilayer heterostructure films were elucidated using spherical aberration-corrected transmission electron microscopy (AC–TEM), high-resolution X-ray…

The authors, conducting research related to the analysis of heat transfer processes in bar bundles, utilize both model calculations and experimental studies. One of the experimental techniques used in this field is thermography^32,33. By employing…

Upon compression, the known phase transitions in Na were observed in good agreement with previous investigations^15,24,27. The Na samples annealed into quasi-single crystals at the oP8 → tI19 phase transition at 133 GPa, and these crystals…

Time series data analysis in education

Numerous studies have been conducted in educational data analysis, focusing on leveraging time series data derived from clickstream activities. Clickstream data represents the sequential recording of user…
