The NIST codebook-based deterministic random bit generators are analyzed in the context of being indistinguishable from random. Upper and lower bounds based on the probability of distinguishing the output are proven. These bounds imply that the security of the designs are bounded by the codebook width, or more precisely on the property that the codebooks act like a random permutation, as oppose...

Calibration is a common practice in image steganalysis for extracting prominent features. Based on the idea of reembedding, a new set of calibrated features for audio steganalysis applications are proposed. These features are extracted from a model that has maximum deviation from human auditory system and had been specifically designed for audio steganalysis. Ability of the proposed system is t...

Let K and L be compact convex sets in Rn. The following two statements are shown to be equivalent: (i) For every polytope Q ⊆ K having at most n+ 1 vertices, L contains a translate of Q. (ii) L contains a translate of K. Let 1 ≤ d ≤ n − 1. It is also shown that the following two statements are equivalent: (i) For every polytope Q ⊆ K having at most d+ 1 vertices, L contains a translate of Q. (i...

INTRODUCTION Scientific evidence supports the synergy between biomedical and behavioral interventions aimed at preventing the transmission of HIV as a strategy to eradicate AIDS. OBJECTIVE To characterize comparatively the benefits from biomedical and behavioral interventions to prevent HIV transmission. METHODS Narrative review. We performed a comparative analysis of the benefits of studie...

materials exhibit significant creep behavior at temperatures above 40% of their absolute melt temperature. lead, tin and their alloys are such materials which experience significant creep behavior in room temperature. one of the most important applications of the tin-lead alloys is soldering electronic circuits in electronic industry, and for lead are isolation walls and wet batteries. room tem...

1. A novel analysis is introduced for the sequential organization of behavioral elements derived from the ergodic theory of nonlinear dynamical systems and statistical mechanics of physical systems. 2. This analysis yields the fluctuation spectrum of local dynamical entropies, S (h), which quantifies the contributions of subsequences with different degrees of association between elements to the...

The classical twin design (CTD) is the most common method used to infer genetic and environmental causes of phenotypic variation. As has long been acknowledged, different combinations of the common environment/assortative mating, and additive, dominant, and epistatic genetic effects can lead to the same observed covariation between twin pairs, meaning that there is an inherent indeterminacy in ...

MOTIVATION Mathematical models are the only realistic method for representing the integrated dynamic behavior of complex biochemical networks. However, it is difficult to obtain a consistent set of values for the parameters that characterize such a model. Even when a set of parameter values exists, the accuracy of the individual values is questionable. Therefore, we were motivated to explore st...

A circuit-level methodology for top-down hierarchical design and nodal simulation of microelectromechanical systems (MEMS) is presented. An abstract layout view is introduced as a geometrically intuitive MEMS representation that is transformed into a schematic suitable for behavioral simulation. Suspended-MEMS inertial sensors, resonant actuators and filters are designed using a small set of ge...
