(Polymat, 2020)We study properties of truncations in the dual and intertwining process in the monotone case. The main properties are stated for the time-reversed process and the time of absorption of the truncated intertwining process.
-
(Elsevier, 2017)This paper studies which social networks maximize trust and welfare when agreements are implicitly enforced. We study a repeated trust game in which trading opportunities arise exogenously and a social network determines ...

(2011)We report on the preparation of WO3 nanostructures using tungsten wire and iron wool in a domestic microwave oven. Pure WO3 nanoparticles were octahedral or rhombohedral while iron containing nanoparticles were spheroidal. ...
-
(Elsevier, 2020)Three amphiphilic carbon nanotube-supported Ni catalysts have been prepared and tested regarding their emulsifying properties for the hydrogenation of furfural. The solid catalysts and emulsions were systematically ...
-
(Elsevier, 2014)One of the main difficulties using multi-point statistical (MPS) simulation based on annealing techniques or genetic algorithms concerns the excessive amount of time and memory that must be spent in order to achieve ...
-
(Elsevier, 2020)Water contamination is increasingly an important issue in developing and under developed countries. The main cause of water contaminations are industrial dyes and toxic chemicals. Hence many technologies are being developed ...
-
(American Physical Society, 2017)A detailed analytical and numerical study of the spin wave modes of the free layer of a nanopillar spin torque nano-oscillator (STNO) has been performed as a function of the magnetostatic interaction between the free and ...
-
(Amer Inst Physics, 2015)While spoof plasmons have been proposed in periodic arrays of sound-hard inclusions, we show that they also exist when inclusions are penetrable. Moreover, we show that their wavelength can be tuned by the impedance mismatch ...

(American Physical Society, 2019)© 2019 authors. Published by the American Physical Society.Spontaneous emergence of self-organized patterns and their bifurcations towards a regime of complex dynamics in nonequilibrium dissipative systems is a paradigm ...
-
Turbulent transport mechanisms on the heat confinement in tunnels by using low-velocity air curtains (Pergamon-Elsevier, 2020)Simulations with the Fire Dynamics Simulator (FDS) were performed to study the ability of Double Stream-Twin Jets (DS-TJ) air curtains to confine heat. Numerical simulations aimed to model a 1:34 scale tunnel, equipped ...
-
(PERGAMON-ELSEVIER SCIENCE LTD, 2008-12)A Matlab program (TBCOSIM) is provided for co-simulating a set of stationary or intrinsic Gaussian random fields in R-3, whose simple and cross-covariance functions are fitted by a linear model of coregionalization. It ...
-
(Universidad de Chile, 2013)El 11 de marzo de 2011 un terremoto de 8,9 grados en la escala de Richter golpeó las costas de Japón. Tras el terremoto, un tsunami azotó las instalaciones de la central nuclear de Fukushima I, las olas del tsunami alcanzaron ...
-
(2009)We discuss the origin of the optical variations in the Narrow line Seyfert 1 galaxy NGC 4051 and present the results of a cross-correlation study using X-ray and optical light curves spanning more than 12 years. The ...
-
(Springer New York LLC, 2019)Information Systems Frontiers is a leading international journal that publishes research at the interface between information systems and information technology. The journal was launched in 1999. In 2019, the journal ...
-
(Elsevier, 2019)The manifestations of the dipolar interaction in magnetic nano-devices can take subtle forms. In this work, we address the effects of dipolar interactions on skyrmions textures. The so-called twisted skyrmion is a natural ...

(Association for Computing Machinery, 2017)Today online social networks seem to be good tools to quicklymonitor what is going on with the population, since they provideenvironments where users can freely share large amounts of infor-mation related to their own ...
