    Abstract: The present invention describes the use of regenerated celluloses (RC) and (ORC) oxidized regenerated celluloses in the manufacture of scaffolds for drug delivery and tissue engineering. The RC and ORC are biodegradable and biocompatible. The carboxyl, aldehyde, or ketone groups present on the ORC scaffold serve as sites for cell, drug, protein and/or peptide attachment or further chemical modification to induce cell adhesion and subsequent proliferation. The method of manufacture of these membrane structures is simple, and produces flexible structures that maintain their strength when hydrated.

    Abstract: Aspects of the disclosed technology provide solutions for generating summaries of a source text based on user specified content parameters. In some aspects, a process of the disclosed technology can include steps for receiving a first source text, the source text having a first textual attribute, receiving a content parameter, providing the source text and the content parameter to a machine-learning (ML) model, and receiving, from the ML model, a proto text based on the source text and the content parameter, wherein the proto text has second textual attribute, and wherein the second textual attribute is different than the first textual attribute. Systems and machine-readable media are also provided.

    Abstract: Various embodiments of a method and system for determining sets of variant items are described. Various embodiments may include a system configured to generate multiple item pairs each corresponding to a particular item and another item determined to be similar to the particular item. For the particular item and the other item, each item pair may include a respective sequence of text strings (e.g., a title). For each item pair, the system may perform a corresponding text alignment and determine one or more misalignments of the item pair. The system may also assign a similarity score to each item pair; the similarity score may be dependent on the misalignment(s) determined for the particular item pair. Based on each aligned item pair and the similarity score assigned to that aligned item pair, the system may generate an indication specifying that each of a set of items are variants of each other.

    Abstract: Methods and systems are disclosed comprising a trap/event registration mechanism wherein a management system in a device network registers each trap/event type on a separate unique listener port. Each unique port number has intelligent binding of the kind of trap/event that can be received thereat. Each trap/event type is tightly bound to the special unique listener port so that the management system will know by virtue of receiving the trap/event at the unique port what kind of trap/event occurred on the device.
