We demonstrate the slowing light effect by exciting the negative Goos-Hänchen effect originating from the fundamental degeneracy oscillatory mode within negative refractive waveguides (NRWs). In the work, we construct three kinds of metamaterial-base NRWs, including an anisotropic plasmonic waveguide operated at multiple incidences, a discrete dielectric metamaterial waveguide, and a monolithic tapered...
The impact of gold nanoparticles to stress fibers (SFs) in HUVEC cells was studied by cutting the SFs from their mid-point with a femtosecond laser and recording their recoil dynamics in the real time.
In order to study ventilation or to extract other functional information of the lungs, intra-patient volume registration of scans at different time instances is valuable as an examination tool. Volume registration is fundamental to multiple medical imaging algorithms. Specially, non-rigid registration of thoracic CT scans taken at different time instances can be used to detect new nodules more reliably...
In this work, we proposed a new method for segmenting coronary arteries automatically in computed tomography angiography (CTA) data sets which allows the coronary pathologies to be reliably detected. Region growing is firstly applied to give the initial segmentation of coronary arteries. However, most applications in the field of medical image processing require precise estimation. Based on the initial...
This paper describes the design and implementation of the mobile power station monitoring instrumentation under Windows CE 6.0 operating system with embedded microprocessor S3C6410. For improving the communication capabilities of traditional mobile power station monitoring instrumentation, a new Ethernet interface using the DM9000E core chip is designed. After transplanting the chip's driver, the...
Under the condition of photon limited, optical signal emitted by the ultra-weak point target is discrete photon flux, which is significantly different from the imaging feature of strong light. The theoretical analysis shows that the statistical properties of photon detection events subject to the Poisson process. In this paper, a new method of choosing threshold range, which bases on the criterion...
This paper proposes a novel nonlinear manifold learning method for addressing the ill-posed problem of occluded human action analysis. As we know, a person can perform a broad variety of movements. To capture the multiplicity of a human action, this paper creates a low-dimensional manifold for capturing the intra-path and inter-path contexts of an event. Then, an action path matching scheme can be...
Human management is the most important factor in university administration. The leaders of college should apply the incentive mechanism to college management based on the characteristics and education law of their universities, and fully arouse tutors enthusiasm and creative spirit, improve the management efficiency. There's no doubt that all of these are based on people-oriented management.
Clustering ensembles can combine multiple partitions generated by different clustering methods into a final superior clustering result. Compared to single clustering algorithm, it can provide better solutions in terms of robustness, novelty and stability. In this paper, we proposed a new method named CEMF, i.e., Clustering Ensembles Based on Multi-classifier Fusion. We combine the clustering ensembles...
After the instruction of FCS and Time, a new proxy signature is proposed. The new scheme not only has the properties of proxy signature, but also greatly improves the security.
