Long non coding RNA FOXP4‐AS1 exerted crucial functions in various human cancers, while its role in non‐small cell lung cancer (NSCLC) remains unclear. A total of 30 pairs of NSCLC tissues and matched adjacent normal tissues were used to evaluate the expression of FOXP4‐AS1 and miR‐3184‐5p. Cell proliferation was assessed by CCK‐8 assay and colony formation assay. Cell apoptosis was measured by flow...
The unsteadiness of the low altitude platforms leads to uneven light and shade in the azimuth of synthetic aperture radar (SAR) images. The traditional method for the azimuth intensity adjusting of SAR images has two important disadvantages. The first is its discontinuity of the normalization factor, and the second is its inapplicability on regions with broken terra of very weak or very strong back...
Due to its radial velocity, the range walk (linear term of range migration) of a moving target in synthetic aperture radar (SAR) image is usually bigger than that of the stationary target. Hence in the time domain after range cell migration correction, the trajectory of most moving target is usually characterized by an approximate sloping line, while the trajectory of stationary targets is lines parallel...
A wideband active phased array antenna using open-ended rectangular waveguide as radiating element is investigated. The results of computation and simulation show the antenna has very high simultaneous bandwidth over 20% and wide beam scanning capabilities up to ±45° in X band. It can be used in very high resolution (better 0.1 m) SAR/GMTI imaging radar.
The bistatic forward-looking SAR with geostationary illuminator and UAV receiver is different from the airborne bistatic SAR in geometry configuration. The paper combines an ellipsoid geometry with forward-looking characteristic and study the approach to detect ambiguous scattering points in the scene. The simulation results for different range and moving direction (including the horizontal baseline...
The paper considers an ellipsoid geometry for bistatic SAR with geostationary illuminator and LEO receivers, and deduces its ground resolution formula. In simulation experiments, the ground resolution differences between plane geometry case and ellipsoid geometry case are given, and the forward-looking ground resolution is also been given when the LEO receiver moves along the horizontal baseline direction...
Based on samples from the Enterprises of South of China, this paper investigates the relationships among organizational socialization, person-organization fit and employee performance. The result showed that: organizational socialization had positive impact on person-organization fit; organizational socialization had positive impact on employee performance; person-organization fit had positive impact...
To explore the relationships among intellectual capital, organization culture; firm performance, 198 Chinese enterprises participated in this investigation. The results indicated that bureaucratic culture positively influenced organization capital, innovative and supportive culture positively influenced human cap-ital, relational capital was affected by supportive culture, and three aspect of intellectual...
This paper firstly describes the processing of Range-Doppler imaging algorithm and FFT interpolation for range cell migration correction, and then forms a improved range-doppler algorithm for SAR imaging with combining the two methods, which has much less computation time. In order to eliminate computation further, the Pruning FFT technique is used.
To explore relationships among organizational learning, organizational innovation and organizational core competence, 267 enterprises participated in this investigation. The result indicated that organization learning not only has direct affection but also has indirect affection on organizational core competence through organizational innovation.
ROBONOVA-1 robot is a kind of new type humanoid robot which can offer educators, students and robotic hobbyists a complete robot package. In order to better study and develop the function of this robot, according to the analysis of its configuration and gait, a seven bar linkage mechanism is established. The forward walking trace of the robot is planned by using the method of geometry constraints...
The problem of how to determine the position of equivalent nadir point of bistatic SAR with geostationary illuminator and low earth orbit (LEO) or unmanned air vehicle (UAV) receivers is very important. Considering high-orbit (or huge-range) characteristic of geostationary bistatic SAR the paper treats the earth surface as an ellipsoid surface and gives several models related to range. After studying...
To explore the relationships among social capital, innovative capabilities, knowledge sharing and firm performance, Chinese enterprises participated in this investigation. We found that social capital influenced innovative capabilities, while innovative capabilities influenced knowledge sharing and firm performance positively. Besides, knowledge sharing influenced firm performance positively. And...
To explore the relationships among human resource system, organizational learning, knowledge sharing and firm performance, Chinese enterprises participated in this investigation. We found that HRM system influenced organizational learning while organizational learning influenced knowledge sharing and firm performance positively, and knowledge sharing also had a direct influence on firm performance...
This study focuses on the role of trust, knowledge sharing within the relationship between organizational socialization and creative behavior. Use multiple regression analysis and structure equation model with a sample of 311 employee from the industry in south of China. The aim of this research is to discover how organizational socialization, trust, knowledge sharing and creative behavior interact...
The performance of Space-Based Radar (SBR) to detect air or ground moving targets is influenced by earth clutter, so an effective algorithm to suppressing clutter can be designed if knowing the power and distribution of earth clutter. In this paper, based on the model of airborne pulse-doppler radar, the model of SBR on power density spectrum of earth clutter in range-doppler space is deduced, and...
This paper explores the interaction of organizational culture, intellectual capital and fire performance. Based on survey data from 167 companies in China, our result shows that both organizational culture hasn't positive firm performance, and intellectual capital has positive effects on firm performance, which demonstrates that intellectual capital significantly mediated the effect of organizational...
According to several mathematical models related to slant range and Doppler of the bistatic SAR with arbitrary geometry configuration, the concept of equivalent velocity is presented and the equivalent velocity divided by the Doppler bandwidth B can be used for calculating the azimuth resolution. The quantitative relation between the equivalent velocity and the receiver velocity parvoarrpar is studied...
To explore the relationships among knowledge sharing, innovative capabilities and firm performance, Chinese enterprises participated in this investigation. We found that knowledge sharing influenced innovative capabilities while innovative capabilities influenced firm performance positively, but knowledge sharing didn't have a direct influence on firm performance. As anticipated, the intervening effect...
