The interpretation of magnetic field data at low magnetic latitudes is difficult because the vector nature of the magnetic field increases the complexity of anomalies from magnetic rocks. The most obvious approach to this problem is to reduce the data to the magnetic pole, where the presumably vertical magnetization vector will simplify observed anomalies. However, RTP requires special treatmen...

Label free tracking of small bio-particles such as proteins or viruses is great utility in the study biological processes, however experiments are frequently hindered by weak signal strengths and a susceptibility to scattering impurities. To overcome these problems we here propose novel technique leveraging enhanced sensitivity both interferometric detection strong field confinement surface pla...

potential fields are due to complex distribution of sources related to susceptibility and mass density variations for magnetic and gravity field respectively. in researching the lateral heterogeneous of different geological bodies, in particular their edge location potential field has some advantages. we mainly refer to linear features such as fault, folding axis, dyke, trend and border of the ...

background dynamic contrast-enhanced magnetic resonance imaging (dce - mri) has been widely used in the management of breast cancer, and its diagnostic value in breast imaging has been demonstrated. there have only been a few reports regarding the usefulness of pre-contrast imaging. knowledge about clinically significant findings of preoperative, pre-contrast t1 and t2 mr images will allow more...

The construction of Gabor’s complex signal—which is also known as the analytic signal—provides direct access to a real one–dimensional (1-D) signal’s local amplitude and phase. The complex signal is built from a real signal by adding its Hilbert transform—which is a phase-shifted version of the signal—as an imaginary part to the signal. Since its introduction, the complex signal has become an i...

The presented paper considers the uplink transmission in base station (BS) cooperation schemes where mobile terminals (MTs) in adjacent cells share the same physical channel. We consider single-carrier with frequency-domain equalization (SC-FDE) combined with iterative frequency-domain receivers based on the iterative block decision feedback equalization (IB-DFE). We study the quantization requ...

We present a real-time method for rendering global illumination effects from large area and environmental lights on dynamic height fields. In contrast to previous work, our method handles inter-reflections (indirect lighting) and non-diffuse surfaces. To reduce sampling, we construct one multi-resolution pyramid for height variation to compute direct shadows, and another pyramid for each indire...

In this paper we consider the synthesis of a bandpass signal from complex-envelope samples using a polyphase conversion structure based on periodically nonuniform output samples. This approach provides the flexibility to independently choose the sampling rate and carrier frequency, overcoming the restrictions of reconstruction from uniformly spaced output samples. Key to the design of such a sy...
