We analyze the infrared behavior of the two and four-point functions for the massless O(N) model in Lorentzian de Sitter spacetime, using the 1/N expansion. Our approach is based in the study of the Schwinger-Dyson equat...

In order to develop an approach to evaluate the preabsorptive behavior of supramolecular aggregate carriers, three commercial oral formulations of a mixture of lipophilic and hydrophilic vitamins dispersed in water-glyce...

The computational resources need by the scientific community to solve problems is beyond the current available infrastructure. Performance requirements are needed due constant research progress, new problems studies or d...

Nos\'e has modified Newtonian dynamics so as to reproduce both the canonical and the isothermal-isobaric probability densities in the phase space of an N-body system. He did this by scaling time (with s) and distance (wi...

Abstract This paper draws on the social and behavioral sciences in an endeavor to specify the nature and microfoundations of the capabilities necessary to sustain superior enterprise performance in an open economy with r...

During performance of attention-demanding cognitive tasks, certain regions of the brain routinely increase activity, whereas others routinely decrease activity. In this study, we investigate the extent to which this task...

"This thesis investigates whether a low-cost brushed DC motor can be used reliably in an actively controlled dual-reel actuation system despite the thermal and energetic challenges associated with motorization. Three low...

Based on recent developments in the empirical modeling of the short-run dynamics of inflation, we estimate a "Hybrid New Keynesian Phillips Curve" for Argentina over the period 1993-2003, which assumes that while a fract...

The aim of the present study was to prepare, characterize and in-vitro evaluation of a Winsor-IV type microemulsion based drug delivery system incorporating celecoxib as BCS class-II model drug. Attempts were made to pre...

Parallel/distributed programming is a complex task that requires a high degree of expertise to fulfill the expectations of high performance computation. The Master/Worker paradigm is one of the most commonly used because...

In this paper we define an evolution mechanism with formal semantics using the metamodeling methodology [Geisler et al.98] based on dynamic logic. A remarkable feature of the metamodeling methodology is the ability to de...

"En esta tesis se analiza el comportamiento dinámico de los puentes basados en comparadores criogénicos de corriente (CCC) a lazo abierto y a lazo cerrado, utilizando técnicas de la teoría de control y con el objetiv...

"The transition to renewable energy sources is reshaping energy systems globally. Germany is a leading example of this shift, having significantly increased its renewable energies (RE) generation in recent years, particu...

El propósito del trabajo consiste en explicitar el comportamiento dinámico del sistema económico a que el modelo Kaldoriano del ciclo da lugar. Vale decir, busca explicar la existencia y la persistencia temporal de lo...

El presente trabajo se asoma al comportamiento social y estatal ante la desapación física de Eva Duarte de Perón, primer icono del peronismo. Para desentramar el accionar del gobierno y la sociedad, decidimos recurrir...

Various heterogeneous catalytic reactions, when performed on a flux reactor (i.e. on open systems) under UHV conditions display complex spatiotemporal patterns. Specifically, TPR, Work Function (WF) measurements (both g...

Tesis Energía y Ambiente (maestría) - Instituto Tecnológico de Buenos Aires - Karlsruher Institut für Technologie, Karlsruhe, 2020 Two-phase flows with phase change are a useful phenomenon for small-scale cooling dev...

"We investigate the role of connection density in an adaptive network model of chaotic units that dynamically rewire based on their internal states and local coherence. By systematically varying the network's connectivit...

How should firms decide whether and when to invest in new capital equipment, additions to their workforce, or the development of new products? Why have traditional economic models of investment failed to explain the beha...

Information technology (IT) acceptance research has yielded many competing models, each with different sets of acceptance determinants. In this paper, we (1) review user acceptance literature and discuss eight prominent ...
