  • Publication number: 20230406370
    Abstract: A vehicle is configured to operate in a first mode in a cantilevered manner from a left side of the vehicle; in a second mode in a cantilevered manner from a right side of the vehicle; and in a third mode in which the vehicle is supported from beneath in a non-cantilevered manner. The vehicle comprises a number of wheel assemblies to facilitate operation in first, second and third modes. The vehicle is configured to navigate between first mode and second mode at junctions offering both options by electing different combinations of wheel engagement and disengagement.

  • Publication number: 20220241260
    Abstract: Pharmaceutical compositions of metabotropic glutamate 5 receptor (mGlu5) antagonists or a pharmacologically acceptable salt thereof are disclosed. The compositions contain the therapeutic active compound with non-ionic polymer and ionic polymer, binder and fillers in either matrix pellet, matrix tablet or coated pellets. The compositions provide a pH-independent in vitro release profile with NMT 70% in one hour, NMT 85% in 4 hour, and NLT 80% in 8 hours. The compositions are useful for the treatment of CNS disorders, such as Treatment-Resistant Depression (TRD) and Fragile X Syndrome.
