Article Abstract
A new spectral distribution data file is set up by handling Arai's experimental data of spectral distribution, through the procession of interpolation and fitting. The distance of wavelength is 0.002 nm. The data file is applied to our FPM program and then to the analysis of refractory steels GH131. Correlation between theoretical and measured intensities is good. Results of theoretical influence coefficient method and fundamental parameter method are consistent with certified values; the relative error is smaller than 1% to Cr and Ni. The results show the accuracy is improved and the application range of FP and SFP is enlarged.

The electronic structure, spectroscopic constants, and transition parameters of the diatomic molecule Magnesium monosulfide (MgS) were investigated using high-level multi-reference configuration interaction calculations with the Davidson correction (MRCI+Q) and a consistent basis set for both Mg and S atoms. Potential energy curves and dipole moment functions were computed, allowing for accurate predictions of rovibrational energy levels. Key transition properties, including radiative lifetimes and Franck-Condon factors, were evaluated for transitions within the ground electronic state and the first excited singlet state.

The photonic flat band, defined by minimal dispersion and near-zero group velocity, has facilitated significant advances in optical technologies. The practical applications of flat bands, such as enhanced light-matter interactions, require efficient coupling to far-field radiation. However, achieving controlled coupling between flat bands and their corresponding localized modes with far-field radiation remains challenging and elusive.

Narrow-linewidth lasers are essential for coherent optical applications, including communications, metrology, and sensing. Although compact semiconductor lasers with narrow linewidths have been demonstrated, achieving high spectral purity generally necessitates passive external cavities based on photonic integrated circuits. This study presents a theoretical and experimental demonstration of a monolithic optical injection locking topological interface state extended (MOIL-TISE) laser.

Recognizing hand gestures from surface electromyography (sEMG) signals is crucial for neural interfaces and human-machine interaction. However, developing subject-generic models remains challenging due to substantial inter-subject variability. Complicating matters further, the muscle groups driving gestures with varying degrees of freedom (DoFs) often overlap, producing highly convoluted feature distributions across subjects and DoFs.

Significance: The spatial and temporal distribution of fluorophore fractions in biological and environmental systems contains valuable information about the interactions and dynamics of these systems. To access this information, fluorophore fractions are commonly determined by means of their fluorescence emission spectrum (ES) or lifetime (LT). Combining both dimensions in temporal-spectral multiplexed data enables more accurate fraction determination while requiring advanced and fast analysis methods to handle the increased data complexity and size.
