متن کاملTwo Jovian-mass Planets in Earthlike Orbits
We report the discovery of two new planets: a 1.94MJup planet in a 1.8 yr orbit of HD 5319, and a 2.51MJup planet in a 1.1 yr orbit of HD 75898. The measured eccentricities are 0.12 for HD 5319b and 0.10 for HD 75898b, and Markov chainMonte Carlo simulations based on the derived orbital parameters indicate that the radial velocities of both stars are consistent with circular planet orbits.With ...

متن کاملLarge-scale calcium waves traveling through astrocytic networks in vivo.
Macroscopic changes in cerebral blood flow, such as those captured by functional imaging of the brain, require highly organized, large-scale dynamics of astrocytes, glial cells that interact with both neuronal and cerebrovascular networks. However, astrocyte activity has been studied mainly at the level of individual cells, and information regarding their collective behavior is lacking. In this...
متن کاملLaser-induced fluorescence and FT-Raman spectroscopy for characterizing patinas on stone substrates.
This article reports on a compositional investigation of stone patinas: thin colored layers applied for protective and/or aesthetic purposes on architectural or sculptural substrates of cultural heritage. The analysis and classification of patinas provide important information of historic and artistic interest, as their composition reflects local practices, the availabilities of different mater...
