However, with a small parent body, crystal settling in low gravity is limited by high- ly turbulent environment.. Several authors suggested that limited crystal settling is

The plot of the noise figure of merit normalized to pixel length and resistance.. is shown in Figure

explanations for the absence of a massive envelope: (1) K2-55b drifted into the inner cavity of the disk via type I migration just as the envelope was starting to accumulate; (2)

Based on the survey data (composed of 75 decisions for each of the 70 survey participants, totaling 5250 data points), we computed the proportion of “Yes /No/Uncertain” decisions

The interest of the work carried out on the Gallica logs persuaded the BnF and Télécom ParisTech to add a further stage to the research, this time lasting four months

The above lemma is interesting because it decomposes the network transfer matrix into the local coding based into a prodoct of n matrices, where each matrix in the product captures

All MAS experiments were conducted using a hr-MAS Bruker probe in the same 300 MHz system as the relaxation experiments. After loading the MAS sample rotor, the sample

Three processes are taken into account for the study of the hydraulic behavior: the evolution of the mechanical state (damage), the drying effect (evolu- tion of the degree
