Metric Options: Counts1 Year3 YearSelecting the 1-year or 3-year option will change the metrics count to percentiles, illustrating how an article or review compares to other articles or reviews within the selected time period in the same journal. Selecting the 1-year option compares the metrics against other articles/reviews that were also published in the same calendar year. Selecting the 3-year option compares the metrics against other articles/reviews that were also published in the same calendar year plus the two years prior.
Example: if you select the 1-year option for an article published in 2019 and a metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019. If you select the 3-year option for the same article published in 2019 and the metric category shows 90%, that means that the article or review is performing better than 90% of the other articles/reviews published in that journal in 2019, 2018 and 2017.

Article Description
A common condition of many artificial satellites around the Earth is thatthey orbit on highly eccentric and/or highly inclined orbits. In this work we studythe secular dynamics of these bodies and we present some of their dynamical aspects.Highly eccentric satellites experience different forces along their trajectories, as theirorbit tends to cross multiple regions in the space around the Earth, making relevant theeffects of atmospheric drag, when the orbit enters the atmosphere, or the solar radiationpressure, when it is further away from the Earth. This means that one needs to take intoaccount different forces, whose magnitude drastically depends on the orbital elementsof the satellite. Besides, highly inclined orbits are important in the study of satellitedynamics, as large values of the inclination might provoke an increase of the eccentricity,when the satellite is close to a lunisolar resonance. An accurate force model is developedfor treating highly eccentric and highly inclined orbits, which includes the geopotential(limited to the most important harmonic coefficients), the effects of Moon and Sun(which are treated as third bodies perturbations), the secular effects of the atmosphericdrag and the solar radiation pressure, using simple models for the density of the Earth’satmosphere and the Sun’s radiation, respectively. Using canonical transformations wecalculate quasi integrals of the motion called proper elements. Finally, we implementmachine learning algorithms to efficiently cluster satellite fragments, using their properelements, in highly eccentric orbits, including cases where the dissipation, caused by theatmospheric drag, is relevant for the dynamics.
