Joint Multichannel Motion Compensation Method for MIMO SAR 3D Imaging

International Journal of Antennas and Propagation, 2015
The multiple-input-multiple-output (MIMO) synthetic aperture radar (SAR) system with a linear antenna array can obtain 3D resolution. In practice, it suffers from both the translational motion errors and the rotational motion errors.

KDM7A and KDM1A inhibition suppresses tumour promoting pathways in prostate cancer

Molecular Oncology, EarlyView.
Treatment resistance is a major challenge for patients with advanced prostate cancer. This study examined an alternative approach to target the major prostate cancer‐promoting pathway by targeting epigenetic factors, whose levels are higher in tumours.

Superresolution versus Motion Compensation-Based Techniques for Radar Imaging Defense Applications

EURASIP Journal on Advances in Signal Processing, 2010
Radar imaging of noncooperative targets is an interesting application of all-weather high-resolution coherent radars. However, these images are usually blurred when using the standard range-Doppler algorithm, if a long coherent processing interval (CPI ...

Motion compensated de-interlacing with adaptive global motion estimation and compensation [PDF]

Proceedings 2003 International Conference on Image Processing (Cat. No.03CH37429), 2004
A motion compensated de-interlacing method with adaptive global motion estimation and compensation is proposed to recover the defects of interlaced video sequence with camera panning, rotating or zooming. GME and GMC are used to recover the change of the whole picture due to camera motions.

Polarization‐resolved femtosecond Vis/IR spectroscopy tailored for resolving weak signals in biological samples using minimal sample volume

FEBS Open Bio, EarlyView.
Unique biological samples, such as site‐specific mutant proteins, are available only in limited quantities. Here, we present a polarization‐resolved transient infrared spectroscopy setup with referencing to improve signal‐to‐noise tailored towards tracing small signals. We provide an overview of characterizing the excitation conditions for polarization‐
