Abstract: An example of an array includes a support, a cross-linked epoxy polyhedral oligomeric silsesquioxane (POSS) resin film on a surface of the support, and a patterned hydrophobic polymer layer on the cross-linked epoxy POSS resin film. The patterned hydrophobic polymer layer defines exposed discrete areas of the cross-linked epoxy POSS resin film, and a polymer coating is attached to the exposed discrete areas. Another example of an array includes a support, a modified epoxy POSS resin film on a surface of the support, and a patterned hydrophobic polymer layer on the modified epoxy POSS resin film. The modified epoxy POSS resin film includes a polymer growth initiation site, and the patterned hydrophobic polymer layer defines exposed discrete areas of the modified epoxy POSS resin film. A polymer brush is attached to the polymer growth initiation site in the exposed discrete areas.

Abstract: Methods, apparatus and computer program product that may include receiving, by one or more servers of a group-based communication platform and from a client of a first user with administrative privileges and associated with a first organization, a request to generate a shared communication channel on the group-based communication platform. A shared communication channel may be generated based on the request. A second request may be received by the one or more servers to provide at least one second user associated with a second organization access to the shared communication channel. Access may be provided to the second user. A message communication may be rendered in a shared communication channel interface associated with the shared communication channel with a graphical indicator that indicates the message communication is associated with the first organization.

Abstract: System and method to produce an anonymized cohort having less than a predetermined risk of re-identification. The method includes receiving a data query of requested traits for the anonymized cohort, querying a data source to find records that possess at least some of the traits, forming a dataset from at least some of the records, and grouping the dataset in time into a first boundary group, a second boundary group, and one or more non-boundary groups temporally between the first boundary group and second boundary group. For each non-boundary group, calculating maximum time limits the non-boundary group can be time-shifted without overlapping an adjacent group, calculating a group jitter amount, capping the group jitter amount by the maximum time limits and by respective predetermined jitter limits, and jittering said non-boundary group by the capped group jitter amount to produce an anonymized dataset. Return the anonymized dataset.

Abstract: Methods and systems to de-identify a longitudinal dataset of personal records based on journalistic risk computed from a sample set of the personal records, including determining a similarity distribution of the sample set based on quasi-identifiers of the respective personal records, converting the similarity distribution of the sample set to an equivalence class distribution, and computing journalistic risk based on the equivalence distribution. In an embodiment, multiple similarity measures are determined for a personal record based on comparisons with multiple combinations of other personal records of the sample set, and an average of the multiple similarity measures is rounded. In an embodiment, similarity measures are determined for a subset of the sample set and, for each similarity measure, the number of records having the similarity measure is projected to the subset of personal records. Journalistic risk may be computed for multiple types of attacks.

Abstract: Provided is a group-based communication interface, on a computing device, configured to display a defined preview of a resource. The computing device receives a group-based message including a resource request that identifies a requested resource and a resource address. The computing device compares the resource address with a list of subscribed resource addresses and determines from the comparison of the resource address and the subscribed resource addresses that the resource address is associated with a resource provider and is thus a subscribed resource address. In response to determining that the resource address is the subscribed resource address, the computing device provides a defined preview request comprising authentication information to the resource provider, receives defined preview data from the resource provider, and renders the defined preview of the resource based on the defined preview data to the group-based communication interface associated with the group-based message.
