Cancer nanotherapeutics are progressing at a steady rate; research and development in the field has experienced an exponential growth since early 2000's. The path to the commercialization of oncology drugs is long and carries significant risk; however, there is considerable excitement that nanoparticle technologies may contribute to the success of cancer drug development. The pace at which pharmaceutical...
The Solar Polar Orbit Telescope (SPORT) mission is proposed to observe the origination and propagation of the interplanetary coronal mass ejections (ICMEs), monitor its long-term behavior and forecast the near earth space weather. A time shared synthetic aperture interferometric radiometer with clock scan is chosen as the main payload instrument to fulfill the objectives. In this paper, the preliminary...
In this paper, we introduce an approach to the design of odd-length biorthogonal wavelet filter banks based on semidefinite programming employing Bernstein polynomials. The method is systematic and renders a simple optimization problem, yet it offers wavelet filters ranging from maximally flat to maximal passband/stopband width. The odd-length biorthogonal filter pairs are then used in multi-focus...
Recently, a new concept of rotation scanning synthetic aperture interferometric radiometer (RS-SAIR) has been receiving more and more attentions for its advantage of much simpler configuration with looser requirements of antenna elements. In this article, we investigate the imaging theory of RS-SAIR, and introduce the pseudo-polar FFT algorithm to deal with the polar u-v samples. It only involves...
Applying synthetic aperture interferometric radiometer (SAIR) in near field imaging has been receiving great interest in the recent years. Because the traditional far-field Fourier imaging theory is not valid in near-field condition, developing the proper near-field imaging techniques is the major desirable objective of near field SAIR applications. This work is devoted to establish an effective near...
Densely aggregated β-amyloid peptides are believed to play a key role in the pathogenesis of Alzheimer’s disease. Amyloid plaques are a potential target for molecular imaging to determine the clinical status of Alzheimer’s disease. Phase-contrast X-ray imaging combined with computed tomography is a promising technique that can be used to visualize the physical density of structures in biological tissues...
