The effect of a small amount of noise on the standard mapping is considered. Whenever the standard mapping possesses accelerator modes (where the action increases approximately linearly with time), the diffusion coefficient contains a term proportional to the reciprocal of the variance of the noise term. At large values of the stochasticity parameter, the accelerator modes exhibit a universal b...

This paper introduces the constrained version of the Affine Projection Algorithm. The new algorithm is suitable for linearly-constrained minimum-variance applications, which include beamforming and multiuser detection for communications systems. The paper also discusses important aspects of convergence and stability of constrained normalized adaptation algorithms in general. It is shown that no...

MOTIVATION We consider the problem of estimating values associated with gene expression from oligonucleotide arrays. Such estimates should linearly track concentration, yield non-negative results, have statistical guarantees of robustness against outliers, and allow estimates of significance and variance. RESULTS A hierarchy of simple models is used to design robust estimators meeting these g...

We show that the variance of the number of edges in the random sphere of innuence graph built on n i.i.d. sites which are uniformly distributed over the unit cube in R d , grows linearly with n. This is then used to establish a central limit theorem for the number of edges in the random sphere of innuence graph built on a Poisson number of sites. Some related proximity graphs are discussed as w...

This paper further explores the horizon effect in the optimal static and dynamic demand for risky assets under return predictability as documented by Barberis (2000). Contrary to the case of stocks, the optimal demand for long-term Government bonds of a buy-and-hold investor is not necessarily increasing in the investment horizon, and may in fact be decreasing for some initial levels of the pre...

Massive MIMO has become a core technology for the next generation of wireless communications, and non-linear group decoding schemes can achieve better spectral energy efficiency, which in turn leads to higher data rates, especially with assistance non-orthogonal frequency multiple access (NOMA). The purpose this paper is study problems formulating performance such systems. In particular, paper,...

An experiment utilizing Cobb-500 male broilers was conducted to evaluate the effects of vitamin E (d1-α-tocopheryl acetate) supplementation at various concentrations (0, 62.5, 125, 250, or 500 mg/kg of diet) on performance and serum concentrations of Triiodothyronine (T3), Thyroxin (T4), Adrenocorticotropine Hormone (ACTH), and some metabolites and minerals in broilers reared under heat stress ...
