Exhibition preview - Brion Gysin: Calligraffiti of Fire, October Gallery, London, December 11, 2008 - February 14, 2009 Trying to pin down Brion Gysin is a confusing business. At various times during his career the cult figure wrote novels, short

When excavation experts from York Archaeological Trust were commissioned to double the size of the University of York's Heslington campus, they might have had cause for optimism. The skeleton of a man believed to be one of Britain's earliest victims

The two major approaches to sparse recovery are L1-minimization and greedymethods. Recently, Needell and Vershynin developed Regularized OrthogonalMatching Pursuit (ROMP) that has bridged the gap between these two approaches.ROMP is the first stable greedy algorithm providing uniform guarantees.Even more recently,

We address the problem of finding a "best" deterministic query answer to aquery over a probabilistic database. For this purpose, we propose the notion ofa consensus world (or a consensus answer) which is a deterministic world(answer) that minimizes the expected

Motivation: Profile hidden Markov Models (pHMMs) are a popular and veryuseful tool in the detection of the remote homologue protein families.Unfortunately, their performance is not always satisfactory when proteins arein the 'twilight zone'. We present HMMER-STRUCT, a model construction algorithmand

The problem of sampling a discrete-time sequence of spatially bandlimitedfields with a bounded dynamic range, in a distributed,communication-constrained, processing environment is addressed. A central unit,having access to the data gathered by a dense network of fixed-precisionsensors, operating under stringent inter-node

In this pedagogical article, we present a simple direct matrix method foranalytically computing the Jacobian of nonlinear algebraic equations that arisefrom the discretization of nonlinear integro-differential equations. The methodis based on a formulation of the discretized equations in vector form

Digital identity management intra and inter information systems, and, serviceoriented architectures, are the roots of identity federation. This kind ofsecurity architectures aims at enabling information system interoperability.Existing architectures, however, do not consider interoperability ofheterogeneous federation architectures, which rely on different

In this paper a greedy algorithm to detect conflict cliques in intervalgraphs and circular-arc graphs is analyzed. In a graph, a stable set requiresthat at most one vertex is chosen for each edge. It is equivalent to requiringthat at most

We consider the problem of finding equivalent minimal-size reformulations ofSQL queries in presence of embedded dependencies [1]. Our focus is onselect-project-join (SPJ) queries with equality comparisons, also known as safeconjunctive (CQ) queries, possibly with grouping and aggregation. For SPJqueries, the

This paper presents a scheduling framework that is configured for, and usedin physic systems. Our work addresses the problem of scheduling variouscomputationally intensive and data intensive applications that are required forextracting information from satellite images. The proposed solution allowsmapping of

We design a 3/2 approximation algorithm for the Generalized Steiner Treeproblem (GST) in metrics with distances 1 and 2. This is the first polynomialtime approximation algorithm for a wide class of non-geometric metric GSTinstances with approximation factor below 2.

There are three wide releases this week, including the only action film of the month of December, The Day the Earth Stood Still. There's no doubt it will be the biggest hit of the week. The only real question is
