Abstract: This paper aims to obtain an analytic approximation to the evolution of circular orbits governed by the Earth’s J2$J_{2}$ and the luni-solar gravitational perturbations. Assuming that the lunar orbital plane coincides with the ecliptic plane,… read more here.

Abstract: BACKGROUND The prognostic value of classifying the degree of metastatic lymph node regression grade after neoadjuvant chemoradiotherapy remains unclear. The aim was to assess the prognostic value of lymph node regression grade in patients with… read more here.
