Rhythmic behaviors such as breathing, walking, and scratching are vital to many species. Such behaviors can emerge from groups of neurons, called central pattern generators, in the absence of rhythmic inputs. In vertebrates, the identification of the cells that constitute the central pattern generator for particular rhythmic behaviors is difficult, and often, its existence has only been inferre...

Messages: a mechanism for intergrated communication and computation. 25 cost of implementing demand-driven eduction in the generator is negligible. Clearly, it is important to not only exercise the GLU programming model in expressing diverse applications, but also to develop abstract architectures that are inherently more scalable, thus eeectively exploiting less coarse-grain parallelism. Refer...

We detail several methods used in the production of pseudorandom numbers for scalable systems. We will focus on methods based on parameterization, meaning that we will not consider splitting methods. We describe parameterized versions of the following pseudorandom number generation: 1. linear congruential generators 2. linear matrix generators 3. shift-register generators 4. lagged-Fibonacci ge...

The need of software-flexible stream ciphers has led to several alternative proposals in the last few years. One of them is a new Pseudo Random Number Generator (PRNG), named N-adic Summation-Shrinking (NSumSG), which architecture is described in this paper. It uses N-1 parallel working slave summation generators and one N-adic summation generator, controlling the nonlinearity in the generator....

In this paper we argue that hand-writing a program generator generator has a number of advantages compared to generating a program generator generator by self-application of a partial evaluator. We show the basic principles of how to construct a program generator generator by presenting a program generator generator for a skeletal language, and we argue that it is not more difficult to use the ...

UNLABELLED The (68)Ge/(68)Ga generator provides an excellent source of positron-emitting (68)Ga. However, newly available "ionic" (68)Ge/(68)Ga radionuclide generators are not necessarily optimized for the synthesis of (68)Ga-labeled radiopharmaceuticals. The eluates have rather large volumes, a high concentration of H(+) (pH of 1), a breakthrough of (68)Ge, increasing with time or frequency of...

it is shown that there are exactly seventy-eight 3-generator 2-groups of order $2^{11}$ with trivial schur multiplier. we then give 3-generator, 3-relation presentations for forty-eight of them proving that these groups have deficiency zero.

De, Trevisan and Tulsiani [CRYPTO 2010] show that every distribution over n-bit strings which has constant statistical distance to uniform (e.g., the output of a pseudorandom generator mapping n− 1 to n bit strings), can be distinguished from the uniform distribution with advantage by a circuit of size O(2 2). We generalize this result, showing that a distribution which has less than k bits of ...
