We show that Multivariate Public Key Cryptosystems (MPKCs) over fields of small odd prime characteristic, say 31, can be highly efficient. Indeed, at the same design security of 2 under the best known attacks, odd-char MPKC is generally faster than prior MPKCs over F2k , which are in turn faster than “traditional” alternatives. This seemingly counter-intuitive feat is accomplished by exploiting...

Collective dynamics on small-world networks emerge in a broad range of systems with their spectra characterizing fundamental asymptotic features. Here we derive analytic mean field predictions for the spectra of small-world models that systematically interpolate between regular and random topologies by varying their randomness. These theoretical predictions agree well with the actual spectra (o...

[1] The tidal flow field in a basin of small dimensions with respect to the tidal wavelength is calculated. Under these conditions, the tide becomes a standing wave oscillating synchronously (with a flat water surface) over the whole basin. The shallow water equations can thus be strongly simplified, expressing the discharge vector field in terms of a potential function and a stream function. T...

Following an initiative formalized in April 2016—formally known as ARL West—between the U.S. Army Research Laboratory (ARL) and University of Southern California’s Institute for Creative Technologies (USC ICT), a field experiment was coordinated and executed in the summer of 2016 by ARL, USC ICT, and Headwall Photonics. The purpose was to image part of the USC main campus in Los Angeles, USA, u...

Small particle’s manipulation is one of the important problems in micro-technology. It has many advantages to apply AC electric field for the manipulation of small particles. With the using of forces generated by an electric field, it is possible to create very compact devices for the particle handling. Since no moving machine parts are involved, it could be reduced the overall energy consumpti...
