VLT/ISAAC H-band spectroscopy of embedded massive YSOs [PDF]
, 2003 We have performed intermediate resolution (R = 5000), high signal-to-noise H-band spectroscopy of a small, initial sample of three massive embedded young stellar objects (YSOs), using VLT/ISAAC.

An Evolutionary Algorithm for Improved Diversity in DSL Spectrum Balancing Solutions
EURASIP Journal on Advances in Signal Processing, 2010 There are many spectrum balancing algorithms to combat the deleterious impact of crosstalk interference in digital subscriber lines (DSL) networks. These algorithms aim to find a unique operating point by optimizing the power spectral densities (PSDs) of

Radio spectra of a sample of X-ray selected BL Lacs [PDF]
, 2004 We present simultaneous multifrequency radio observations for a complete subsample of 26 XBLs from the Einstein Extended Medium-Sensitivity Survey, obtained with the Very Large Array (VLA). Spectra are computed using fluxes at 20, 6 and 3.6 cm.

Factors shaping the abundance and diversity of the gut archaeome across the animal kingdom
Nature Communications, 2022 Here, by analyzing 250 species of animals covering a large taxonomic spectrum, the authors show that archaea are common constituent of the animal gut throughout the animal kingdom, and identify six main genera/families of gut archaea revealing their ...

The sudden appearance of CO emission in LHA 115-S 65 [PDF]
, 2012 Molecular emission has been detected in several Magellanic Cloud B[e] supergiants. In this Letter, we report on the detection of CO band head emission in the B[e] supergiant LHA 115-S 65, and present a K-band near-infrared spectrum obtained with the ...

Symmetry-based coarse-graining of evolved dynamical networks
, 2015 Networks with a prescribed power-law scaling in the spectrum of the graph Laplacian can be generated by evolutionary optimization. The Laplacian spectrum encodes the dynamical behavior of many important processes.
