Cognitive deficits are a core feature of major depressive disorder (MDD). However, there are no previous studies that directly compare cognitive performance between first-episode drug-naive depressive patients (FDDP) and medicated depressive patients (MDP). Therefore, the aim of this study was to investigate whether there were the differences in cognitive functions between FDDP and MDP. Sixty-two...
The Bat uses Frequency Modulated (FM) echolocation calls to accurately estimate range and resolve closely spaced as 2 us objects. In this paper, a modified echolocation model for multiple targets in 3-dimensional space using hyperbolic frequency modulation emission is proposed. The method to modify parameters in all blocks using LFM waveform echolocation model is given. The simulation results show...
Visual target tracking is one of fundamental research of computer vision field and play an important role in the surveillance application, but it is also one of the difficulties due to the instability of the tracking scene. In this paper, we analyze the major drawbacks of the original Kernelized Correlation Filter (KCF) tracker which causes tracking failure when target experience complicated scenarios...
Estimating and detecting red tide is particularly challenging when using remotely sensed observations. Aqua-Terra MODIS provides a high resolution spatio-temporal coverage to detect red tide blooms. Both in-situ and satellite data were analyzed for red tide period and non-red tide period in this study. The red tide period was between September and November, 2011 while the non-red tide period was between...
Data mining is to extract the potentially useful knowledge and information from large amounts of data. How to dig up effective, reliable, understandable, and interesting association rules from vast amounts of information to help people make decisions has become an urgent problem to be solved. People want to use a reasonable evaluation method to measure reliability or validity of association rules,...
In clinical diagnosis and treatment, the images which we wanted are taken in obscuration or the object which is caught is moving during imaging, which will cause the SNR of the images to be very low, and make the image registration difficulty. To improve the quality of image quality, the joint transform correlator is used to measure the image motion between the serial images, then the images are aligned...
Shaper-assisted autocorrelation is developed to characterize single-cycle pulses. The correlation signal show significantly improved signal-to-noise ratio and thus accuracy in pulse characterization when compared to cross-correlation obtained by splitting the spectral components of the pulse.
