DOI: 10.1007/s00190-019-01315-0
Abstract: We present improved modelling to compute centre of mass (CoM) offsets for spherical geodetic satellites and derive new values for the spacecraft LAGEOS, LAGEOS-2, Etalon-1/2, Starlette, Stella, LARES, and Ajisai for all system configurations of… read more here.

DOI: 10.1016/j.jbiomech.2021.110486
Abstract: During walking, falling is most likely to occur towards the side of the supporting lower limb during the single stance. Timely lateral redirection of the centre of mass (CoM) preceding the no-return position is necessary… read more here.

DOI: 10.1088/1361-6552/aa70d7
Abstract: Bodies can have very weird trajectories when tossed into the air. The amazing motion of a water bottle flip is qualitatively described as related to the position of the centre of mass (CM) with respect… read more here.

DOI: 10.1088/1361-6552/aa9c6a
Abstract: In sports, it is very common to see athletes performing jumps, where they impose rotations to their own bodies' elements and intentionaly change their moment of inertia around the centre of mass (CM). When this… read more here.

DOI: 10.1134/s1063778817060023
Abstract: We calculate the differential cross sections for proton elastic scattering on the exotic halo nuclei 6He and 8He at energies around ~0.7 GeV at the momentum transfers squared up to 0.30 (GeV/c)2 and investigate the… read more here.
