  • Patent number: 11990241
    Abstract: A computer readable storage medium is provided. When contents of the computer readable storage medium are executed by a processor, multi-photon imaging may be performed on a histopathological section containing tumor environment information, and pathological partitioning of a tumor microenvironment may be further performed through image processing. A value of each collagen feature parameters, such as a morphological feature parameter, an energy feature parameter and a texture feature parameter, may be extracted from a tumor tissue region, an invasive margin (IM) region and a normal tissue (N) region. An inter-region difference and a variation may be calculated according to feature parameters of regions. A collagen feature scoring model may be established. A collagen feature score may be calculated with the collagen feature parameters input to the model.

  • Publication number: 20240139348
    Abstract: Disclosed are a multi-modality molecular imaging probe, and a preparation method and use thereof. The multi-modality molecular imaging probe has an ABA structure, with a magnetic functional unit of a gadolinium complex at the center, and two identical phosphorescent functional units of an iridium complex, which are reasonably integrated into the same one complex molecule. The multi-modality molecular imaging probe simultaneously introduces two optical functional units of the iridium complex and one magnetic functional unit of a gadolinium chelate in the same one complex molecule, which exhibits magnetic-optical dual functional properties. It therefore could be used to prepare both a contrast agent for magnetic resonance imaging and an optical probe for optical imaging.

  • Patent number: 11930008
    Abstract: Example subscription information configuration methods and a communications device are described. One example method includes receiving a first device identifier by a network device from a first terminal device in a first access mode and receiving a second device identifier from a second terminal device in a second access mode. The network device determines whether the first device identifier matches the second device identifier to identify legality of the first terminal device. If the first device identifier matches the second device identifier, it indicates that the first terminal device is a legal terminal device. The network device sends subscription information of the first terminal device to the first terminal device in the first access mode, so that the first terminal device successfully accesses a network by using the subscription information.

  • Patent number: 9559978
    Abstract: The subject matter described herein includes methods, systems, and computer readable media for intelligent optimization of digital signal processor (DSP) resource utilization in a media gateway. In one method, it is determined in a media gateway whether predetermined conditions exist for DSP-less IP-IP switching for a call. In response to determining that the predetermined conditions exist, DSP-less IP-IP switching is implemented for the call in the media gateway. After implementing the DSP-less IP-IP switching for the call, it is determined whether a predetermined event occurs that requires insertion of DSP resources during the call. In response to determining that the predetermined event occurs, the DSP resources are inserted into the call during the call.

  • Patent number: 7792150
    Abstract: Methods, systems, and computer program products for providing transcoder-free operation in a media gateway are disclosed. In one method, first and second lists of media encoding rates and corresponding indices used by first and second media endpoints of a media stream connection are received. It is determined whether transcoder-free operation is possible for the media stream connection based on the first and second lists. In response to determining that transcoder-free operation is possible for the media stream connection, a transcoder-free connection is established in the media gateway between the first and second endpoints using a single digital signal processor to monitor and map between indices and encoding rates used by the first and second endpoints during the media stream connection.
