Abstract: A controller, located at a network resource or as part of an access point device, can configure an access point device to selectively configure the backhaul (BH) and fronthaul (FH) connections of a network based on one or more network parameters associated with the network devices within the network. The controller can associate a 6 GHz band or high frequency band to the BH connection with legacy network devices associated to a lower frequency band for a FH connection while other network devices are associated to a higher frequency band, such as a 5 GHz band, for a FH connection based on the one or more network parameters. The controller can dynamically switch the other network devices to a 6 GHz or higher frequency band after an update of the one or more network parameters indicate network performance, for example, will be improved by the switch.

Abstract: A cluster-based approach and template-based approach are combined to segment brain matter from a three-dimensional MRI image of voxels. The morphological information captured by the template-based approach may be used to refine the segmentation produced by the cluster-based approach. Conversely, the “similarity” information captured by the cluster-based approach may be used to refine the segmentation produced by the template-based approach.

Abstract: A process for the preparation of Molnupiravir, an antiviral drug under investigation for the treatment of Covid-19, is provided including reacting 2?-3?-isopropylidene cytidine with isobutyric anhydride in the presence of a base to obtain 5?-isobutyric ester having an amide impurity. Treating the reaction mixture with para-toluenesulphonic acid monohydrate results in acetonide deprotection giving pure isobutyric cytidine tosylate salt which is free from the amide impurity. Conversion of tosylate salt into free base and reacting with hydroxylamine gives Molnupiravir.

Abstract: In one aspect, a computer-implemented method corrects a multi-sphere head model used in dipole localization for a set of magnetic field sensors (MEG sensors) by replacing ghost spheres with replacement spheres that are not ghost spheres. One type of ghost sphere completely encloses the brain volume but is so large that a center of the sphere is outside the brain volume. Another type of ghost sphere lies entirely outside the brain volume. Various approaches for correcting ghost spheres are disclosed.
