  • Patent number: 11955688
    Abstract: Aspects described herein include devices, wireless communication apparatuses, methods, and associated operations for heatsinks integrating millimeter wave and non-millimeter wave operation. In some aspects, an apparatus comprising a millimeter wave (mmW) module is provided. The apparatus includes at least one mmW antenna and at least one mmW signal node configured to communicate a data signal in association with the at least one mmW antenna. The apparatus further includes mixing circuitry configured to convert between the data signal and a mmW signal for communications associated with the at least one mmW antenna. The apparatus further includes a heatsink comprising a non-mmW antenna and a non-mmW feed point coupled to the non-mmW antenna. The non-mmW feed point is configured to provide a signal path to the non-mmW antenna for a non-mmW signal. The heatsink is mechanically coupled to the mmW module.

  • Publication number: 20200248268
    Abstract: A method for estimating a risk for a subject suffering from an urothelial carcinoma is provided, including measuring an expression level of at least one miRNA in a sample of the subject, and the miRNA is selected from miR-1274, miR-19a, miR-30, and miR-708; and comparing the expression level of the same miRNA in the sample to that of a control for estimating whether the subject has the risk of suffering from the urothelial carcinoma or not. A kit for estimating a risk for a subject suffering from an urothelial carcinoma is also provided, including at least one reagent for detecting an expression level of at least one miRNA as above mentioned in a sample of the subject.
