  • Publication number: 20240124767
    Abstract: A light-emitting composition containing first and second light-emitting markers. The first light-emitting marker comprises a first light-emitting material and a first binding group configured to bind to a first target analyte. The second light-emitting marker comprises a second light-emitting material which is different from the first light-emitting material and a second binding group which is different from the first binding group and which is configured to bind to a second target analyte. A luminescent lifetime of the first light-emitting material is shorter than a luminescent lifetime of the second light-emitting material. The difference in lifetimes of the first and second light-emitting materials may be used to distinguish between the first and second target analytes in a sample, e.g. by time-gated flow cytometry.

  • Patent number: 11880679
    Abstract: In accordance with an embodiment, described herein is a system and method for supporting patching in a multi-tenant application server environment. The system can associate one or more partitions with a tenant, for use by that tenant, wherein a partition is a runtime and administrative subdivision or slice of a domain. A patching process can take advantage of high-availability features provided by an application server clustering environment, to apply patches in a controlled, rolling restart, which maintains a domain's ability to operate without interruption, or with zero downtime. The process can be used to automate complex or long running tasks, including preserving an unpatched or prior version of an application server, application, or other software component for possible rollback, or providing automatic reversion in the event of an unrecoverable error.

  • Publication number: 20240002236
    Abstract: The present invention relates to a method for fabrication of blue-fluorescent and non-toxic nanodiamonds from atmospheric particulate matters including total solid suspended particulate matter (TSPM) and particulate matter with size less than 10? (PM10). Mostly, the present invention provides an efficient mitigation process for particulate pollutant by conversion of these pollutants (PM and TSPM) into non-toxic high-value product such as nanodiamond by using the ultrasonic-assisted chemical oxidation method. This method is environmental friendly, simple, and biocompatible for the production of nanodiamonds from such atmospheric particulate matter.

  • Patent number: 11842524
    Abstract: A mechanism is provided for implementing an optical character recognition (OCR) error correction mechanism for correcting OCR errors. Responsive to receiving a document in which OCR has been performed, the mechanism assesses the document to identify a set of OCR errors generated by an OCR engine that performed the OCR using a set of visual embeddings. Responsive to identifying the set of OCR errors, the mechanism analyzes each character of a plurality of sentences within the document to generate a high-dimensional embedding for the characters of the plurality of sentences within the document. The mechanism then linguistically corrects each OCR error in the set of OCR error. The mechanism utilizes ground truth information and the set of visual embeddings to verify that character stream is linguistically correct. Responsive to verifying that the character stream is linguistically correct, the mechanism outputs an OCR error corrected document to a user.

  • Patent number: 11829424
    Abstract: Discovering second-order documents and latent custodians in an e-discovery system is provided. A list of first-order documents and document custodians within a base state of the e-discovery system are identified based on a plurality of terms corresponding to a meet and confer practice for a legal matter instance. The plurality of terms is masked within the first-order documents. The first-order documents having the plurality of terms masked are divided into groups. A list of second-order documents is generated from a group of documents. A list of second-order document custodians is generated based on corresponding custodian relationships to second-order documents. Finally, each second-order document custodian in the list of second-order document custodians that has a corresponding rank exceeding a defined rank threshold level is identified as an official document custodian in the e-discovery system.

  • Publication number: 20230347384
    Abstract: A smart conveyor belt web service is provided. A network device generates recipes for multiple orders. Each recipe provides sorting instructions for a conveyor system. The network device transfers an identifier for a first recipe to a queue of active recipes and sends the first recipe to a server device for the conveyor system. The network device receives a recipe-complete status message indicating completion of the first recipe. The network device deletes the indicator for the first recipe from the queue based on receiving the recipe-complete status message and transfers a second recipe to the queue of active recipes to initiate processing of another order.

  • Publication number: 20230300083
    Abstract: In accordance with an embodiment, described herein is a system and method for supporting multi-tenancy in an application server, cloud, on-premise, or other environment, which enables categories of components and configurations to be associated with particular application instances or partitions. Resource group templates define, at a domain level, collections of deployable resources that can be referenced from resource groups. Each resource group is a named, fully-qualified collection of deployable resources that can reference a resource group template. A partition provides an administrative and runtime subdivision of the domain, and contains one or more resource groups. Each resource group can reference a resource group template, to bind deployable resources to partition-specific values, for use by the referencing partition. A tenant of the application server or cloud environment can be associated with a partition, or applications deployed therein, for use by that tenant.

  • Publication number: 20230032267
    Abstract: In accordance with an embodiment, described herein is a system and method for supporting partitions in a multitenant application server environment. In accordance with an embodiment, an application server administrator (e.g., a WLS administrator) can create or delete partitions; while a partition administrator can administer various aspects of a partition, for example create resource groups, deploy applications to a specific partition, and reference specific realms for a partition. Resource groups can be globally defined at the domain, or can be specific to a partition. Applications can be deployed to a resource group template at the domain level, or to a resource group scoped to a partition or scoped to the domain. The system can optionally associate one or more partitions with a tenant, for use by the tenant.
