Abstract: The present disclosure proposes a hierarchical beamforming method and a base station and a user equipment using the same. The method includes following steps. A network entry procedure is performed via a plurality of coarse beams by using a superframe header of a superframe corresponding to each of the coarse beams. In response to a success message associated with the network entry procedure being received, a network entry done message is transmitted by using a preferred coarse beam among the coarse beams. A user equipment (UE) connection is performed via a plurality of fine beams within a direction range of the preferred coarse beam, so as to determine a preferred fine beam by using a frame header of a basic frame corresponding to each of the fine beams, and perform a data packet transmission by using a packet transmission block of the basic frame corresponding to the preferred fine beam.

Abstract: Provided is a detection method for heavy metal ions that includes the following steps. A waste water is flowed through an ion-imprinted polymer tube for adsorbing at least two kinds of target heavy metal ions. The ion-imprinted polymer tube is rinsed to remove a non-target object from the ion-imprinted polymer tube. The target heavy metal ions in the ion-imprinted polymer tube are desorbed by using an acid liquid. An electrochemical method is performed to detect concentrations of the target heavy metal ions.

Abstract: A method of ultrasound imaging and a corresponding ultrasound scanner are provided. The method includes the steps of receiving an echo signal induced by an ultrasonic plane wave transmission from a transducer of an ultrasound scanner, resampling the echo signal in time domain and/or space domain, performing a spectrum zooming on a band of interest (BOI) of an input signal, performing a Fourier transform on a result of the spectrum zooming, and generating an ultrasound image based on a result of the Fourier transform. The input signal is generated based on the resampling of the echo signal.
