Recent experimental discovery of extended self-similarity (ESS) was one of the most interesting developments, enabling precise determination of the scaling exponents of fully developed turbulence. Here we show that the ESS is consistent with the Navier-Stokes equations, provided the pressure -gradient contributions are expressed in terms of velocity differences in the mean field approximation (...

Abstract. We study the problem of how a “living” system complex in structure can respond perfectly to local changes in the environment. Such a system is assumed to consist of a distributed “living” medium and a hierarchical “supplying” network that provides this medium with “nutritious” products. Because of the hierarchical organization each element of the supplying network has to behave in a s...

Grammatical agreement means that two linguistic units share certain syntactic or semantic features such as gender, number or person. Agreement has a variety of grammatical functions. One of them, called internal agreement, is to signal which words are grouped together as part of the same phrase. This chapter explores how a population might self-organize such an agreement system. We argue that t...

Most previous experiments attempting to establish the existence of the selfserving bias have confounded it with strategic behavior. We design an experiment that controls for strategic behavior (Haman effects), and isolates the bias itself. The self-serving bias that we measure concerns beliefs about the rationality of others. We find very limited support for the existence of the bias. To help u...

__________________________________________________ A central feature in contemporary discussions of selfknowledge concerns the epistemic status of mental selfascriptions, such as “I have toothache” or “I believe that p”. The overall project of such discussions is to provide an account of the special status of mental self-ascriptions vis-à-vis other knowledge-claims, including ascriptions of men...

We introduce and study the problem of computing the similarity self-join in a streaming context (sssj), where the input is an unbounded stream of items arriving continuously. The goal is to find all pairs of items in the stream whose similarity is greater than a given threshold. The simplest formulation of the problem requires unbounded memory, and thus, it is intractable. To make the problem f...

Digital cameras record only one color component per pixel, red, green or blue. Demosaicking is the process by which one can infer a whole color matrix from such a matrix of values, thus interpolating the two missing color values per pixel. The selected color configuration of the sensor usually follows the Bayer color filter array, CFA. Out of a group of four pixels, two are green (in quincunx),...

People perceive similarity between their own personality characteristics and the of others. This association has sometimes been labeled assumed similarity, reflecting interpretation that it is a cognitive bias. Another possibility, however, an interpersonal path to perceived similarity: traits are manifested in behavior may elicit similar or dissimilar from others, people form perceptions based...

We consider Smoluchowski’s equation with a homogeneous kernel of the form a(x, y) = xy + yx with −1 < α ≤ β < 1 and λ := α + β ∈ (−1, 1). We first show that self-similar solutions of this equation are infinitely differentiable and prove sharp results on the behavior of self-similar profiles at y = 0 in the case α < 0. We also give some partial uniqueness results for self-similar profiles: in th...
