1). First, separate molecular networks were created for each dataset individually, while merging near-identical spectra and only keeping spectra that occur at least twice within the dataset to eliminate non-reproducible MS/MS spectra (Fig. 1, step 1). Spectrum annotations were obtained at the ...
on the basis of the IR-excesses in the spectrum of the nearest stellar/substellar systems; discuss some data on the nearest stellar and substellar population; give a list of circumstellar discs discovered within 10 pc from the Sun and their main astrophysical properties; and briefly discuss dis...
Machine Learning Techniques for Cooperative Spectrum Sensing in Cognitive Radio Networks For classification, the K-means clustering algorithm partitions the training feature vectors into K clusters, where each cluster corresponds to a combined ...

HSIC (Gretton et al. year) was an independence criterion based on the eigen-spectrum of covariance operators in reproducing kernel Hilbert spaces (RKHSs), consisting of an empirical estimate of the Hilbert-Schmidt Independence Criterion18. HHG (proposed by Heller et al.) is a powerful test ...
By interacting with the Milky Way galaxy’s natural magnetic field, these axions could be converted back into photons in the X-ray part of the electromagnetic spectrum, Xiao said. Sign up for the Live Science daily newsletter now Get the world’s most fascinating discoveries delivered straight...
Some stargazers are fortunate enough to detect the green hues because the human eye is more sensitive to yellow-green light as opposed to red, according to Iowa State University, so if any color is to be detected from the Orion Nebula it is likely to be at the green end of the spectrum...
The performance of this method, however, will be reduced against a strong background of noisy signals, as the method mainly focuses on the maximum peak position of the constructed singular spectrum, which may result in the loss of important information about other peaks. Other researchers proposed...
