(IOP PUBLISHING LTD, 2008-07-02)The classical action for a three-dimensional rotating particle with time-dependent angular velocity and that submitted to a general linear and quadratic time-dependent potential is explicitly calculated and, via path ...
-
(1988)The dynamics of extended models of charged particles considered as sources of the Reissner-Nordström geometry is analyzed. They consist of spherical bubbles with electric charge and surface tension. Equations of motion for ...
-
(Universidad de Concepción, 2020)Forest and agricultural exports, particularly fruit exports, are one of the backbones of the Chilean economy. In general, the study of this type of exports has been approached from a local perspective, regardless of the ...
-
(2009)Seafood consumption-related diarrhea became prevalent in Chile when the pandemic strain of Vibrio parahaemolyticus serotype O3:K6 reached a region in the south of Chile (Region de los Lagos) where approximately 80% of the ...
-
(2012)Background: Understanding the cellular mechanisms regulating axon degeneration and regeneration is crucial for developing treatments for nerve injury and neurodegenerative disease. In neurons, axon degeneration is distinct ...
-
(1976)To investigate the role of the eosinophil leukocytes in the early oestrogenic responses in the uterus, the kinetics of oestrogen-induced uterine eosinophilia and other parameters of oestrogen stimulation were studied at ...
-
(AMER Geophysical Union, 2021)The 2004-2009 caldera uplift is the largest instrumentally recorded episode of unrest at Yellowstone caldera. We use GPS and Interferometric Synthetic Aperture Radar (InSAR) time series spanning 2004-2015, with a focus in ...
-
(2013)Background: Helicobacter pylori colonization/infection can be transitory or persistent, conditions that have not been thoroughly evaluated in young children. We aimed to characterize the dynamics of H. pylori stool ...
-
(1993)Infectious diseases in human populations are seldom seen as part of a permanently occurring phenomenon in natural ecosystems. Their relationships to predator-prey or host-parasite systems are not evident. The conceptual ...
-
(Universisdad de Chile, 2017)Como otro paso hacia la comprensión de la evolución a lo largo plazo del campo magnético en las estrellas de neutrones, ofrecemos las primeras simulaciones de difusión ambipolar en una estrella esférica. Restringiendonos ...
-
(Cambridge University Press, 2008-05)This paper uses the 1996–2001 National Socioeconomic Survey panel database to analyse poverty dynamics in Chile, drawing a distinction between chronic and transient poverty. We found that while 20 per cent of the ...
-
(2010-04-14)In order to assess the physical mechanisms at stake when giant gas bubbles burst at the top of a magma conduit, laboratory experiments have been performed. An overpressurized gas cavity is initially closed by a thin ...
-
(Deutsche Physikalische Gesellschaft, 2014)We report on the experimental observation and characterization of the bifurcation diagram, dynamical properties and fluctuations of spatially modulated kinks in a shallow one-dimensional fluidized granular layer subjected ...
-
(Emerald Group Publishing Ltd., 2018)© 2018, Emerald Publishing Limited. Purpose: The purpose of this paper is to develop a novel method to analyse dynamic interactions of stakeholders to explain how a set of agents can act by considering the power/influence ...
-
(2010)Precisely synchronized neuronal activity has been commonly observed in the mammalian visual pathway. Spike timing correlations in the lateral geniculate nucleus (LGN) often take the form of phase synchronized oscillations ...
-
(BioMed Central, 2014)Background: Fern-like crystalloids form when a microvolume of tear is allowed to dry out at ambient conditions on a glass surface. Presence of crystalloids in tear “microdesiccates” is used to evaluate patients with ...
-
(ELSEVIER, 2006-07-14)In this paper we present a large scale study on the evolution of the Web structure of the Chilean domain (.cl) from 2000 to 2004, focusing on the Web site transitions in the structure. This is the study of the largest time ...
-
(Elsevier, 2020)The double burden of malnutrition (DBM), defined as the simultaneous manifestation of both undernutrition and overweight and obesity, affects most low-income and middle-income countries (LMICs). This Series paper describes ...
-
(Universidad de Chile. Facultad de Economía y Negocios, 2007-12)Through flows from 3 states, employment, unemployment and out of the labor force, we analyze the dynamics of labor markets in Chile from 1962-2007. We identify some periods of different labor market regimes and relate ...
