  • Publication number: 20250117255
    Abstract: Systems and methods for discovering caller paths in a micro-service graph are disclosed. The system can receive a first request to interact with a first node, wherein the first node is associated with a software application. The system can generate a first bit encoding indicative of the first node. The system can transmit, from the first node, a second request to a second node associated with the software application, wherein the second request is associated with the first request. The system can generate, based on the first bit encoding, a second bit encoding indicative of the first node and the second node. The system can determine, based on the second bit encoding, a sequence of requests.

  • Publication number: 20250084018
    Abstract: A first stream containing 1,3-butadiene, C4 acetylenes, and optionally C3 hydrocarbons, is mixed with a portion of the liquid recycle stream from a C4 acetylene hydrogenation reactor containing hydrogenated C4 acetylenes and a molecular hydrogen-containing stream, the resulting mixed stream is then fed to a C4 acetylene hydrogenation reactor to selectively hydrogenate the C4 acetylenes in the crude butadiene stream without appreciable 1,3-butadiene conversion.

  • Patent number: 12168638
    Abstract: A system and a process for dimerizing cyclopentadiene (CPD) including producing a C6+C7 rich bottoms stream and a C5 rich side draw from a debutanizer, where the C5 rich side draw and at least a portion of the C6+C7 rich bottoms stream are directed to a dimerizer where the CPD is thermally dimerized to dicyclopentadiene (DCPD). DCPD is more stable than CPD and thus safer to handle.

  • Publication number: 20240072217
    Abstract: The present disclosure relates to a lighting component which may comprise a light emitting diode (LED) or laser diode (LD) for generating at least one of blue light or ultraviolet light. A fluoride phosphor matrix may be included, which may be consolidated into a phosphor ceramic structure including at least one of a transparent fluoride ceramic structure or a translucent fluoride ceramic structure, and positioned adjacent to the LED or LD. The phosphor ceramic structure generates at least one of red or orange light when irradiated by the light emitted from the LED or LD. The phosphor ceramic structure exhibits reduced thermal quenching relative to a fluoride particulate structure irradiated by the LED or LD.

  • Publication number: 20230105187
    Abstract: Methods, systems, and computer programs are presented for backing up data to a distributed multichannel storage system. One method includes an operation for detecting, by a distributed backup system (DBS), a request for backing up data from a host to the distributed backup system. The DBS sends a request to a backup agent executing at the host to initiate the backup. The backup agent mounts an endpoint for writing to the DBS and executes a script that writes the data for the backup to the endpoint. Further, the method includes operations for creating a file system stack at the DBS associated with the endpoint, storing data received by the file system stack at the DBS, and detecting, by the DBS, an end of the backup. The DBS sends a command to the backup agent to end the backup and terminates the file system stack at the DBS.

  • Publication number: 20230091233
    Abstract: The present disclosure relates to processes, apparatuses, and systems for the removal of sulfur compounds from a heavy hydrocarbon feed as part of steam cracking processes to produce light olefins. In at least one embodiment, the process includes introducing a hydrocarbon feed having a first sulfur content to a steam cracker to produce a steam cracker effluent having a second sulfur content less than the first sulfur content. The process includes introducing the steam cracker effluent to a fractionation system to produce a light hydrocarbon product stream having a third sulfur content less than the second sulfur content.
