The artifacts of ECG signals include baseline wander (BW), muscle (EMG) artifact, electrode motion artifact and power line interference. In order to get the optimal and robust de-noising algorithm among the generally used de-noising methods based on stationary wavelet transform (SWT), we adjust the signal-to-noise ratio (SNR) of the noisy signal from 1db to(More)
Cetuximab (C225) is a unique agent, targeting epidermal growth factor receptor (EGFR)-positive cancer. However, the therapeutic effect of C225 in EGFR high-expressing non-small cell lung cancer (NSCLC) remains poor. Here, we report that conjugation of C225 with gold nanoparticles (AuNPs) enhances the cytotoxicity of C225 in NSCLC both in vitro and in vivo.(More)
In ECG de-noising, the goal is to recover the valid ECG from the undesired artifacts with the minimum distortion for presenting a signal, which allows easy visual interpretation and auto diagnosis. We adopt three de-noising algorithms based on wavelet packet (WPT), lifting wavelet (LWT) and stationary wavelet transform (SWT) for de-noising ECG signals,(More)
This research proposes a new approach for the control of metameric robot locomotion via phase coordination. Unlike previous studies where global wave-like rules were pre-specified to construct the actuation sequence of segments, this phase coordination method generates robot locomotion by assigning the actuation phase differences between adjacent segments(More)
Background. Surfaced-enhanced laser desorption-ionization-time of flight mass spectrometry (SELDI-TOF-MS) technology plays an important role in the early diagnosis of ovarian cancer. However, the raw MS data is highly dimensional and redundant. Therefore, it is necessary to study rapid and accurate detection methods from the massive MS data. Methods. The(More)
Objective: To understand the spatial and temporal distribution of HIV/AIDS in Hubei province, and provide scientific evidence for the prevention and control of AIDS. Methods: GeoDa software was used for autocorrelation analysis, SatScan 9.2 software was used for statistical analysis of spatial scanning, and finally geographic information system was used for(More)
A real time algorithm embedded in single chip computer (MCU) is presented to count steps precisely. According to the features of the step wave, Chain Code is adopted to encode the signal. Then the Freeman Chain Code is analyzed and modified for signal processing. Steps are detected through recognition of wave group after encoding. The experimental result(More)
1 This study aims to analyze vessel traffic characteristics in the Singapore Strait. The real-2 time vessel AIS (Automatic Identification System) based data with about 4 million 3 records are collected from the Lloyd's Marine Intelligence Unit (LIoyd's MIU) database 4 for analysis. The results show that container ships have the largest proportion (36.36%)(More)
Based on SD memory card, the communication & storage system of the embedded portable spectrometer was designed, so the spectrometer can save data and change the analysis model files. In the system, SD card was used to store data files, and the communication function was designed by using serial port to send the file and command and receive the file. So(More)
