  • Publication number: 20240373097
    Abstract: Methods, apparatus, systems, and articles of manufacture are disclosed to determine whether audience measurement meters are co-located. An example apparatus is to, based on a difference between a first sampling time of a first entry of a first log and a second sampling time of a corresponding entry of a second log satisfying a first threshold, determine at least one matching instance of at least one first device identifier of the first entry and at least one second device identifier of the corresponding entry. Additionally, the example apparatus is to populate a variable with the at least one matching instance. The example apparatus is also to, based on a metric satisfying a second threshold, cause transmission of an alert indicating that a first meter and a second meter were co-located during generation of the first log and the second log, the metric based on the at least one matching instance.

  • Publication number: 20230040771
    Abstract: The instant invention concerns a process for fragmenting a polymer chain, comprising an oxidative degradation step wherein the polymer chain is contacted with a reduced form of a metal M and an oxidant such as dioxygen, and wherein the polymer carries covalently bound chemical groups acting as a ligand of said reduced form of the metal M. The invention also relates to methods making use of this fragmentation process as a first step of a degradation process of the polymer especially useful for avoiding the negative impact of a polymer to the environment. In this connection, the invention relates to the use of polymers carrying chemical groups acting as a ligand for a reduced form of a metal M, as a polymer biodegradable in an environment wherein the reduced form of a metal M is present.
