The submillimeter wave or terahertz (THz) band (1 mm-100 microm) is one of the last unexplored frontiers in the electromagnetic spectrum. A major stumbling... C Yeh,F Shimabukuro,Siegel, PH - 《Applied Optics》 被引量: 129发表: 2005年 Diverse Radiofrequency Sensitivity and Radiofrequency Eff...
also has shown a good application prospect in groundwater resources survey, engineering geological exploration and environmental geological survey. To meet the demands for national resources and environmental survey, the resolution, stability and practicability of China's airborne geophysical survey system wi...
2). Network depth was investigated by increasing the number of convolutional layers and the number of layer sets (convolution followed by max pooling). Convolutional layers provide learned filters or kernels that identify small features in the spectrum, while max pooling layers decrease dimensionality ...
transmission facilities[41], use metallic materials. Further, novel solutions such as use ofamorphous(soft magnetic Co-based alloys) and conductive (Cu, Ni, Al) metals, with a gap between them to avoid interference, have provided shielding of both low- and high-frequency EM radiations in ...
Traditional Chinese Medicines (TCMs) have been used for centuries for the treatment and management of various diseases. However, their effective delivery to targeted sites may be a major challenge due to their poor water solubility, low bioavailability, and potential toxicity. Nanocarriers, such as ...
The spectral behavior between the solid state and the metal-complexes in solution was very similar, maintaining the same emission spectrum shape, though the alizarin-powdered lake was slightly red shifted in comparison to the chelate in solution. Similar absorption and emission bands for madder lake...

In the frequency-domain approach, TEM data are Fourier-transformed using a smooth-spectrum inversion method, and the recovered frequency response is then inverted. To deal with a large number of grids and a wide range of frequencies in airborne datasets, a method for approximating sensitivities is...
