Abstract. A sign-linear one bit map from the d-dimensional sphere S to the n-dimensional Hamming cube H = {−1,+1}n is given by x 7→ {sign(x · zj) : 1 ≤ j ≤ n} where {zj} ⊂ S. For 0 < δ < 1, we estimate N(d, δ), the smallest integer n so that there is a sign-linear map which has the δ-restricted isometric property, where we impose normalized geodesic distance on S, and Hamming metric on H. Up to...

BMJ Case Rep Published online: [please include Day Month Year] doi:10.1136/bcr-2014205510 DESCRIPTION A twin male infant weighing 820 g was born at 26 weeks of gestation. At birth he received mechanical ventilation, surfactant and subsequently indomethacin treatment for a large patent ductus arteriosus. On day 8 of life he had frequent epi...

To improve traffic safety, an automatic traffic sign detection system would be important to assist the driver. In this paper, an approach for detecting Norwegian speed limit signs is proposed. It consists of three major steps: Color-based filtering, locating sign(s) in an image and detection of numbers on the sign. About 91% correct recognition is achieved for a selection of 198 images. Ongoing...

Synchronous cultures prepared by selection from an elutriating rotor were used to measure activity changes during the cell cycle of the following enzymes: acid phosphatase in Schizosaccharomyces pombe and Saccharomyces cerevisiae, alpha-glucosidase in S. cerevisiae and beta-galactosidase in Kluyveromyces lactis. There was no sign of step rises in activity in acid phosphatase but there were indi...

where ⊂Rn (n≥ 2) is a bounded smooth domain, s ∈ (0, 1), (– )s denotes the fractional Laplacian, λ is a real parameter, the nonlinear term f satisfies superlinear and subcritical growth conditions at zero and at infinity. When λ≤ 0, we prove the existence of a positive solution, a negative solution and a sign-changing solution by combing minimax method with invariant sets of descending flow. Wh...

QCD in the ε-regime at nonzero baryon chemical potential µ is reviewed. The focus is on aspects of the sign problem which are relevant for lattice QCD. It is discussed how spontaneous chiral symmetry breaking and the sign problem are related through the spectrum of the Dirac operator. The strength of the sign problem is linked to the quark mass and the chemical potential. Specific implications ...

We consider s polynomials P 1 ; : : :; P s in k < s variables with coef-cients in an ordered domain A contained in a real closed eld R, each of degree at most d. We present a new algorithm which computes a point in each connected component of each non-empty sign condition over P 1 ; : : :; P s. The output is the set of points together with the sign condition at each point. The algorithm uses s(...

Se urity Notions and Analyses Jee Hea An Abstra t This paper addresses the se urity of authenti ated en ryption s hemes in the publi key setting. We present two new notions of authenti ity that are stronger than the integrity notions given in the symmetri setting [5℄. We also show that hoseniphertext atta k se urity (IND-CCA) in the publi key setting is not obtained in general from the ombinati...
