1. Introduction Water Distribution Systems (WDSs) capable of supplying a sufficient quantity of potable water are one of the key infrastructures for a modern sustainable city. The service quality of WDSs is closely related to water conservation and various detrimental disturbances in WDSs, such as pipe bursts and leaks, will result in significant water loss. World-widely, it is reported that 11...

Behavioral (semantic differential) and neural (Evoked Potentials, EPs) responses were related to connotative meaning. The approach was based on Osgood’s semantic analyses and dimensions of Evaluation (E), Potency (P), and Activity (A). The experimental variables were (I) the semantic class of the stimulus word (E+, E, P+ , P-, A+, A-) and (2) the dimension of the semantic scale (E, P. A) which ...

BACKGROUND Influenza vaccines are effective in protecting against illness and death caused by this seasonal pathogen. The potency of influenza vaccines is measured by single radial immunodiffusion (SRID) assay that quantifies antigenic forms of hemagglutinin (HA). Hydrostatic pressure results in loss of binding of influenza virus to red blood cells, but it is not known whether this infers loss ...

This paper studies labeled sample compression for multi-label concept classes. For a specific extension of the notion of VC-dimension to multi-label classes, we prove that every maximum multilabel class of dimension d has a sample compression scheme in which every sample is compressed to a subset of size at most d. We further show that every multi-label class of dimension 1 has a sample compres...

Let A, B, be finite subsets of an abelian group, and let G ⊂ A×B be such that #A,#B,#{a + b : (a, b) ∈ G} ≤ N . We consider the question of estimating the quantity #{a − b : (a, b) ∈ G}. In [2] Bourgain improved the trivial upper bound of N to N 1 13 , and applied this to the Kakeya conjecture. We improve Bourgain’s estimate further to N 1 6 , and conclude that Besicovitch sets in Rn have Hausd...

The study aims to identify the possibilities offered by academic studies in Cuba for the training of information professionals as marketing managers. A theoretical analysis is conducted of the basic functions of marketing and its information dimension, the specific features of the work of the marketing manager, and the Revista Cubana de Información en Ciencias de la Salud 2014;25(2):234-248 htt...

In this paper we use the theory of computing to study fractal dimensions of projections in Euclidean spaces. A fundamental result in fractal geometry is Marstrands projection theorem, which shows that for every analytic set E, for almost every line L, the Hausdorff dimension of the orthogonal projection of E onto L is maximal. We use Kolmogorov complexity to give two new results on the Hausdorf...
