Laser-enhanced cavitation during high intensity focused ultrasound (HIFU) was studied in vivo using a small animal model. Laser light was employed to illuminate the sample concurrently with HIFU radiation. The resulting cavitation was detected with a passive cavitation detector. The in vivo measurements were made under different combinations of HIFU treatment depths, laser wavelengths, and HIFU...

The sequential and indeterminate behavior of an end-around-carry (EAC) adder is examined. This behavior is commonly overlooked in the literature. Design modifications to impose determinism are provided. These modifications also eliminate the troublesome negative zero found in the one's complement number system.

Two kinds of configuration schemes about eight and ten single-axis vector magnetometers are put forward on the basis of describing the principle of underwater magnetic field localization. The measurement equations of magnetic field magnitude and gradients are educed on condition of two configuration schemes, and that the calculated precisions of both magnetic field magnitude and gradients are c...

The paper introduces an approach for crosstalk-free bitpermute-complement (BPC) permutations routing in hybrid optical variable-stage shuffle-exchange networks (SENs) of size where N=2, and the number of stages can vary in . The number of stages should be asserted as required by a given BPC permutation for its admissibility. The crosstalk is caused by interacting of two optical signals within t...
