Although the goal of clustering is intuitively compelling and its notion arises in many fields, it is difficult to define a unified approach to address the clustering problem and thus diverse clustering algorithms abound in the research community. These algorithms, under different clustering assumptions, often lead to qualitatively different results. As a consequence the results of clustering a...

The input value for the maximum spatial scan extent (K) of a prospective space-time scan statistical (PSTSS) technique is one important parameter that ensures accurate detection of the predictive hotspot of geographical point events. Currently, there is no general consensus on how to determine the optimal value of K that maximises the predictive accuracy, especially in crime hotspot prediction....

We consider the existence of pairs of probability ensembles which may be efficiently distinguished from each other given k samples but cannot be efficiently distinguished given k0 < k samples. It is well known that in any such pair of ensembles it cannot be that both are efficiently computable (and that such phenomena cannot exist for nonuniform classes of distinguishers, say, polynomial-size c...

This letter is in response to the discussion of our recent paper entitled " The effect of parameter uncertainty on achieved safety integrity of safety system " [1]. We are grateful to the discussants for their constructive comments and suggestions, and in particular their insight into our proposed methods to measure safety-related (SR) uncertainty. The detailed response is given below. We agree...

Predictions from science and engineering models depend on several input parameters. Global sensitivity analysis quantifies the importance of each input parameter, which can lead to insight into the model and reduced computational cost; commonly used sensitivity metrics include Sobol’ total sensitivity indices and derivative-based global sensitivity measures. Active subspaces are an emerging set...

This paper investigates the effect of conflict on firms' output value and input misallocation in the context of Palestine during the Second Intifada. Using a unique establishment-level dataset, we compare firms' outcomes and input usage over time across districts experiencing differential changes in conflict intensity. We show how conflict diminishes the total and per-worker value of firms' out...

Phase correlation techniques have been used in image registration to estimate image displacements. These techniques have been also used to estimate optical ow by applying it locally. In this work a di erent phase correlation-based method is proposed to deal with a deformation/translation motion model, instead of the pure translations that the basic phase correlation technique can estimate. Some...

This paper provides an abstract definition of some kinds of logics, called diagrammatic logics, together with a definition of morphisms and of 2-morphisms between diagrammatic logics. The definition of the 2-category of diagrammatic logics rely on category theory, mainly on adjunction, categories of fractions and limit sketches. This framework is applied to the formalization of a parameterizati...

We consider the fully constrained version of the next-to-minimal supersymmetric extension of the standard model (cNMSSM) in which a singlet Higgs superfield is added to the two doublets that are present in the minimal extension (MSSM). Assuming universal boundary conditions at a high scale for the soft supersymmetrybreaking gaugino, sfermion and Higgs mass parameters as well as for the trilinea...

We consider the problem of constructing Concurrent Zero Knowledge Proofs [6], in which the fascinating and useful “zero knowledge” property is guaranteed even in situations where multiple concurrent proof sessions are executed with many colluding dishonest verifiers. Canetti et al. [3] show that blackbox concurrent zero knowledge proofs for non-trivial languages require Ω̃(log k) rounds where k ...
