SMS MAMÁ: TeleSalud aplicada a la gestión de pacientes vía SMS

La investigación-acción consiste sondear el universo de población en Mendoza, en condición de embarazo y realizaracciones preventivas destinadas a la población materna-infantil mediante el uso de las Tecnologías de la Información y lasComunicaciones (TIC) a través de un proyecto socio-sanitario destinado a embarazos de alto riesgo, una importanteproblemática de salud pública por sus elevados niveles de morbimortalidad.La herramienta teleinformática utilizada es un sistema web implementado en un Smartphone con sistema operativo Android,donde corren los servicios de datos, de envío y recepción de mensajes de texto (SMS) y el servidor web que responde a las consultas de los clientes enviándolas a la aplicación. Teniendo en cuenta que el número de dispositivos móviles supera la cantidad de habitantes de la República Argentina, se ve la existencia de una gran probabilidad de que las mujeres embarazadas dispongan y sepan utilizar un teléfono móvil para recibir mensajes de texto y de esta forma, realizar las acciones preventivas propuestas. Una cualidad particular de este trabajo es que la aplicación web está compactada en el celular, sin necesidad de instalar e implementar todos estos servicios en una computadora; por lo tanto solo con este dispositivo es posible gestionar campañas, pacientes, estadísticas, y el envío de los SMS

Unbounded violation of tripartite Bell inequalities

We prove that there are tripartite quantum states (constructed from random unitaries) that can lead to arbitrarily large violations of Bell inequalities for dichotomic observables. As a consequence these states can withstand an arbitrary amount of white noise before they admit a description within a local hidden variable model. This is in sharp contrast with the bipartite case, where all violations are bounded by Grothendieck's constant. We will discuss the possibility of determining the Hilbert space dimension from the obtained violation and comment on implications for communication complexity theory. Moreover, we show that the violation obtained from generalized GHZ states is always bounded so that, in contrast to many other contexts, GHZ states do in this case not lead to extremal quantum correlations. The results are based on tools from the theories of operator spaces and tensor norms which we exploit to prove the existence of bounded but not completely bounded trilinear forms from commutative C*-algebras.Comment: Substantial changes in the presentation to make the paper more accessible for a non-specialized reade

On the multilinear Hausdorff problem of moments

Given a multi-index sequence necessary and sufficient conditions are given for the existence of a regular Borel polymeasure on the unit interval such that . This problem will be called the weak multilinear Hausdorff problemof moments for . Comparison with classical results will allow us to relate the weak multilinear Hausdorff problem with the multivariate Hausdorff problem. A solution to the strong multilinear Hausdorff problem of moments will be provided by exhibiting necessary and sufficient conditions for the existence of a Radon measure on such that where is the -linear moment functional on the space of continuous functions on the unit interval defined by the sequence . Finally the previous results will be used to provide a characterization of a class of weakly harmonizable stochastic processes with bimeasures supported on compact sets

Multiple summing operators on C(k) spaces

In this paper, we characterize, for 1 ≤ p <∞, the multiple (p, 1)-summing multilinear operators on the product of C(K) spaces in terms of their representing polymeasures. As consequences, we obtain a new characterization of (p, 1)-summing linear operators on C(K) in terms of their representing measures and a new multilinear characterization of L∞ spaces. We also solve a problem stated by M.S. Ramanujan and E. Schock, improve a result of H.P. Rosenthal and S.J. Szarek and give new results about polymeasures

Biodiversity among Buffalo genomes.

Archaeozoological data indicate that the water buffalo was domesticated between 4000 and 6000 years ago in the Indus and Yangtze valleys. Historically domestic water buffalo were divided into swamp and river subspecies that differ in morphology, behaviour, geography and chromosome number. The river buffalo has 2n=50 chromosomes and the swamp buffalo has 2n=48 . The swamp buffalo resembles more closely the ancestral wild Bubalus arnee; than the river buffalo. The two subspecies mate only if reared together from calf-hood. River buffalo are mainly found in India, Southwest Asia and the Mediterranean, while swamp buffalo are predominantly in Southeast Asia and China. The International Buffalo Genome Consortium recently sequenced the buffalo genome to create a reference buffalo genome, and has produced low pass whole genome sequences of 48 river buffaloes from 4 breeds: Mediterranean buffalo sampled in Italy, Jaffarabardi and Murrah breeds sampled in Brazil and Nili-Ravi sampled in Pakistan. Analysis of these data identified over 13M SNPs with MAF≥0.05. We used these data to estimate basic population genetics parameters and the genetic structure of the breeds. Expected heterozygosity varied significantly among breeds. The Fst index revealed that a remarkable portion of the total variability is explained by the between breed component. Principal component analysis of individual animals based on a subset of 50K randomly selected SNPs clustered animals from the same breed and showed a clear differentiation among breeds
