<title>Structure analysis of the Polish academic information society using MDS method</title>
2006
The article presents the methodology of webometrics research and analysis aiming at determining similar features of objects belonging to the Polish information society, which uses the Internet and its www resources for communication purposes. In particular, the analysis applies to the selected Polish technical universities. The research was carried out in several phases - on different data groups - with regards to the Internet space and time changes. The results have been presented in a form of two and three-dimensional topography maps. For the purposes of this analysis, the computer methods of multidimensional scaling were used. The research will be further continued for a selected group o…
On the interplay between multiscaling and stocks dependence
2019
We find a nonlinear dependence between an indicator of the degree of multiscaling of log-price time series of a stock and the average correlation of the stock with respect to the other stocks traded in the same market. This result is a robust stylized fact holding for different financial markets. We investigate this result conditional on the stocks' capitalization and on the kurtosis of stocks' log-returns in order to search for possible confounding effects. We show that a linear dependence with the logarithm of the capitalization and the logarithm of kurtosis does not explain the observed stylized fact, which we interpret as being originated from a deeper relationship.
Tierras inundadas: El cultivo del arroz en la España contemporánea (1800-1936)
2002
Editada en la Fundación Empresa Pública El arroz fue una de las diversas dedicaciones agrícolas que permitieron mejorar los rendimientos en las condiciones particulares del mundo mediterráneo. Su implantación, sin embargo, exigió profundas transformaciones en el aprovechamiento del agua y comportó, a causa de las implicaciones sanitarias del cultivo, la intervención estatal. Su inserción en las estructuras agrarias existentes no fue, por tanto, fácil pero posibilitó el uso agrario de áreas de difícil aprovechamiento como la Albufera valenciana, el delta del Ebro y las Marismas del Guadalquivir. Desde la segunda mitad del siglo XIX, además, esta producción tuvo que adaptarse a la competencia…
Evolution of worldwide stock markets, correlation structure and correlation based graphs
2011
We investigate the daily correlation present among market indices of stock exchanges located all over the world in the time period Jan 1996 - Jul 2009. We discover that the correlation among market indices presents both a fast and a slow dynamics. The slow dynamics reflects the development and consolidation of globalization. The fast dynamics is associated with critical events that originate in a specific country or region of the world and rapidly affect the global system. We provide evidence that the short term timescale of correlation among market indices is less than 3 trading months (about 60 trading days). The average values of the non diagonal elements of the correlation matrix, corre…

Bimetallic PdAg nanoparticle arrays from monolayer films of diblock copolymer micelles
2015
MICROSCOPIE+ATARI+EEH:GMA:TBG:NSP:MAO; International audience; The self-assembly technique provides a highly efficient route to generate well-ordered structures on a nanometer scale. In this paper, well-ordered arrays of PdAg alloy nanoparticles on flat substrates with narrow distributions of particle size (6-7 nm) and interparticle spacing (about 60 nm) were synthesized by the block copolymer micelle approach. A home-made PS-b-P4VP diblock copolymer was prepared to obtain a micellar structure in toluene. Pd and Ag salts were then successfully loaded in the micellar core of the PS-b-P4VP copolymer. A self-assembled monolayer of the loaded micelles was obtained by dipping the flat substrate …
