Results achieved by the proposed variable step explicit method is compared to those achieved by a traditional implicit integration based simulator like NgspiceI. The results show

Indeed, the Brillouin gain spectrum is measured in the electrical domain with central frequency of 351 kHz and a natural width of 4.163 kHz, representing in the optical domain

For the second goal, we provide an updated distribution range at high resolution (1 km  1 km UTM grid), which we use in climate-based distribution modelling to esti- mate the past

By measuring the two-point correlation function of galaxy populations that differ in redshift, color, luminosity, star-formation history and bias, and using high-resolution

The stellar evolution model of a red giant with 1.7 M without planet engulfment and with a time-averaged rotation velocity during the main sequence equal to 100 km s −1 shows

Our high- resolution images clearly show that the H 2 emission is not uniformly distributed in a torus around the central star as it has been interpreted from previous
