  • Publication number: 20240168721
    Abstract: A random transient power test signal generator based on three-dimensional memristive discrete map, which utilizes a three-dimensional parallel bi-memristor Logistic map module to generate two pseudo-random sequences, and based on the sequences, uses two waveform output modules to generate transient voltage and transient current signals respectively, thus the random transient power testing signal is obtained. The map can significantly improve the complexity of chaos and greatly extend its range of chaos. In addition, a performance evaluation shows the map has more robust hyperchaotic behavior in much larger chaos range. Moreover, the random sequences generated by the map module combines with DDS, which can generate a transient power signal with completely random period, starting phase and ending phase.

  • Publication number: 20240168027
    Abstract: The invention belongs to the technical field of biomedical testing, and particularly relates to a biomarker for diagnosis, treatment, and prognosis for hepatocellular carcinoma bone metastasis (HCC) and application thereof. The application of biomarker VAPA for preparing a reagent or a kit for diagnosis, treatment, and prognosis for HCC bone metastasis. The application of the reagent that detects VAPA expression levels in blood and tissues for preparing a reagent or kit for diagnosis, treatment, and prognosis for HCC bone metastasis. Compared with the diagnostic kits in the prior art that can only detect bone metastasis after it has occurred, the VAPA described in this invention offers a more specific and sensitive assay kit for the early prediction, diagnosis, disease progression assessment, treatment efficacy evaluation, drug guidance, and prognosis assessment of HCC bone metastasis. Additionally, the VAPA may also serve as a target for therapeutic interventions in bone metastasis.
