mm-DSF: A Method for Identifying Dangerous Driving Behaviors Based on the Lateral Fusion of Micro-Doppler Features Combined.

To address the dangerous driving behaviors prevalent among current car drivers, it is necessary to provide real-time, accurate warning and correction of driver's driving behaviors in a small, movable, and enclosed space. In this paper, we propose a method for detecting dangerous behaviors based on frequency-modulated continuous-wave radar (mm-DSF). The highly packaged millimeter-wave radar chip has good in-vehicle emotion recognition capability. The acquired millimeter-wave differential frequency signal is Fourier-transformed to obtain the intermediate frequency signal. The physiological decomposition of the local micro-Doppler feature spectrum of the target action is then used as the eigenvalue. Matrix signal intensity and clutter filtering are performed by analyzing the signal echo model of the input channel. The signal classification is based on the estimation and variety of the feature vectors of the target key actions using a modified and optimized level fusion method of the SlowFast dual-channel network. Nine typical risky driving behaviors were set up by the Dula Hazard Questionnaire and TEIQue-SF, and the accuracy of the classification results of the self-built dataset was analyzed to verify the high robustness of the method. The recognition accuracy of this method increased by 1.97% compared with the traditional method.

Efficacy of early combination of local radiotherapy and GM-CSF for advanced non-small cell lung cancer treated with icotinib.

BACKGROUND: Lung cancer is a disease that severely endangers human health. Non-small cell lung cancer (NSCLC) accounts for approximately 4/5 of lung cancers. AIMS: To investigate the efficacy of early combination of local radiotherapy and granulocyte macrophage colony-stimulating factor (GM-CSF) for advanced NSCLC treated with icotinib. METHODS: Forty-two patients with stage IV NSCLC complicated with EGFR gene mutation were selected and randomly divided into two groups, with 21 patients in each group. Patients in control group were treated with icotinib, and patients in experimental group were treated with icotinib combined with local radiotherapy and subcutaneous injection of GM-CSF. One-year progression free survival between two groups was compared. RESULTS: Three months after treatment, the efficacy in experimental group was significantly better than that in control group, and objective response rate was 95.24% in experimental group, which was higher than the 71.43% in control group. Patients in experimental group had no differences in white blood cell and neutrophil, but had significantly lower carcino-embryonic antigen and neuron-specific enolase levels and higher CD3+, CD4+, and CD4+/CD8+ than those in control group and before treatment. There were no differences in the proportion of patients with adverse reactions between two groups. One-year progression free survival was significantly better in experimental group than in control group. CONCLUSIONS: Early combination of local radiotherapy and GM-CSF has a significant efficacy for advanced NSCLC accounts for approximately 4/5 of lung cancers treated with icotinib, and it can improve patients' autoimmunity and lengthen progression free survival.

Controllable visibility and resolution of Nth-order Talbot imaging with pseudo-thermal light.

The theoretical proposal for an improved Talbot imaging technique has been analyzed in a periodic object illuminated by a pseudo-thermal light source and detected only by two detectors in two imaging schemes. The improved effect of lensless grating ghost image and Talbot image quality (fringe resolution and visibility) can be attributed to the higher correlation orders N. While at a certain order N, the spatial resolution of Talbot carpet patterns is determined by two-photon bunching effect, which depends on the positions of the periodic object and two detectors and different detection methods. Moreover, the sub wavelength of spatial correlation peaks and Talbot images obtained, when we use two asynchronous scanning detectors or an accelerated scanning detector. The present imaging schemes have the characteristic of the controllable image visibility and resolution, which has a potential application in periodic image reconstructions, sub wavelength resolution microscopy and sub wavelength atom lithography.

Triple-mode squeezing with dressed six-wave mixing.

The theory of proof-of-principle triple-mode squeezing is proposed via spontaneous parametric six-wave mixing process in an atomic-cavity coupled system. Special attention is focused on the role of dressed state and nonlinear gain on triple-mode squeezing process. Using the dressed state theory, we find that optical squeezing and Autler-Towns splitting of cavity mode can be realized with nonlinear gain, while the efficiency and the location of maximum squeezing point can be effectively shaped by dressed state in atomic ensemble. Our proposal can find applications in multi-channel communication and multi-channel quantum imaging.
