Time synchronization is essential for node localization, target tracking, data fusion, and various other Wireless Sensor Network (WSN) applications. To improve the estimation accuracy of continuous clock offset and skew of mobile nodes in WSNs, we propose a novel time synchronization algorithm, the Rao-Blackwellised (RB) particle filter time synchronization(More)
MicroRNAs (miRNAs) have key roles in gene expression and can be employed as biomarkers for early diagnosis of various diseases, especially cancers. Detection of miRNAs remains challenging and often requires detection platforms. Here, a horseradish peroxidase (HRP)-assisted hybridization chain reaction (HCR) for colorimetric detection of miR-155 was(More)
Most researches on the massive multiple-input multiple-output (MIMO) systems are based on the assumption that the MIMO channels are independent, in reality, the above assumption is very difficult to realize when the number of multiple antennas are very large. Hence the simulation on massive MIMO systems under correlated channels has some degree of guiding(More)
Conventional wireless communication system capacity is limited by the worst channel parameters which determine the transmission mode. In this paper, a novel adaptive transmission scheme used in OFDM system is proposed to increase the system capacity by adaptively adjusting the transmission mode depending on channel parameters. In FDD mode, channel(More)
In this study, a new lateral flow nucleic acid biosensor (LFNAB) using hybridization chain reaction (HCR) for signal amplification was developed for visual detection of nucleic acids with high sensitivity and low cost. A "sandwich-type" detection strategy was employed in our design. The sandwich system of capture probe (CP)/target DNA/reporter probe(More)

In order to provide a railcar image-aided navigation technique, aimed to the characters of the railcar scene, it was presented a real time fusion matching algorithm with multi-resolution and multi-direction features. First, this algorithm preprocessed images to depress the influences of disturbs and noises with the method of fast fuzzy edge variation.(More)
