Diving thyroid nodules are a limitation of radiofrequency ablation because the mediastinal component cannot be adequately identified by ultrasound (US).We aim to describe a new technique, the iceberg technique, to overcome this issue and explain our three-year experience of using this novel method.The iceberg technique consists of a two-stage treat
The Effect of Attenuation from Fish Shoals on Long-Range, Wide-Area Acoustic Sensing in the Ocean
Acoustics is the primary means of long-range and wide-area sensing in the ocean due to the severe attenuation of electromagnetic WALLET waves in seawater.While it is known that densely packed fish groups can attenuate acoustic signals during long-range propagation in an ocean waveguide, previous experimental demonstrations have been restricted to s
Optimization of the Weight Processing Algorithm in Multichannel Doppler Filtering
Introduction.The use of non-equidistant pulse sequences as probing radar signals makes it possible to eliminate blind spots in speed and range.However, the implementation of multi-channel Doppler filtering (MDF) based on the classical fast Fourier transform (FFT) algorithm of non-equidistant signal samples in the signal detection problem is associa
