Fermion sign problem in imaginary-time projection continuum quantum Monte Carlo with local interaction
2016
We use the Shadow Wave Function formalism as a convenient model to study the fermion sign problem affecting all projector Quantum Monte Carlo methods in continuum space. We demonstrate that the efficiency of imaginary time projection algorithms decays exponentially with increasing number of particles and/or imaginary-time propagation. Moreover, we derive an analytical expression that connects the localization of the system with the magnitude of the sign problem, illustrating this prediction through some numerical results. Finally, we discuss the fermion sign problem computational complexity and methods for alleviating its severity.
Caviar con Ron: 'Sdelano na Kube'
2015
En Caviar con Ron : ' Sdelano na Kube', Jacqueline Loss y Jose Manuel Prieto analizan la gama vasta de actitudes hacia lo sovietico -desde una minimizacion del impacto sovietico en Cuba a una expresion exagerada de gratitud hacia los “rusos”- que se han encontrado desde que comenzaron su colaboracion investigativa en 2004. Notan que las transformaciones en la memorializacion, de una negacion rotunda a una aceptacion actual que no dudarian de llamar entusiasta, fueron algo que no pudieron anticipar del todo cuando decidieron organizar el que puede considerarse el primer simposio internacional (2007) dedicado a estudiar el impacto del vinculo sovietico en Cuba y publicar el libro Caviar wit…

Tourism in the European economic crisis: Mediatised worldmaking and new tourist imaginaries in Greece
2016
The article interrogates the rationale and origins of changing imaginaries of tourism in Greece in the context of the current economic crisis. We detect a radical change in the ‘picture’ of the country that circulates in global media conduits (YouTube, Facebook, official press websites and personal blogs). We enact a journey into past media representations of Greece as an idyllic peasant and working-class site, but proceed to highlight that such representations are being recycled today by Greeks (especially but not exclusively) living and studying abroad. This stereotype, which focuses on embodied understandings of happiness and well-being, is being challenged by the current economic crisi…
Bordón : revista de pedagogía
2013
Si hay algún elemento que ha destacado sobre otros en la historia de la educación infantil contemporánea, este ha sido, sin lugar a dudas, el juego. Es imposible desligar la actividad lúdica de la vida cotidiana de las primeras edades y, aunque el juego no se reduce únicamente a la infancia, podemos afirmar que el discurso pedagógico al respecto se ha centrado mayoritariamente en este periodo educativo. El presente artículo trata de esbozar algunos de los rasgos formativos del juego infantil, recurriendo para ello a la historia de la educación mediante el análisis de algunos de los discursos, prácticas y testimonios de destacados educadores y educadoras del siglo pasado, interesados todos e…
Inventing Traditions, Raising Expectations. Recent Debates on “Personalized Medicine”
2015
Since the late 1990s, the term “Personalized Medicine” has been coined to enable collaborations between different stakeholders in and outside research units. As a concept, it constitutes an imaginary framework of expectations and claims for a better, patient-centered and efficient health care system. Rather than deciding whether such trends represent “hype” or “hope”, scholars from the social studies of technology and science emphasize that the expectations revolving around new technology are not only accessory parts of scientific inventions or innovation networks. Instead, they regard them essential in shaping these technologies. The aim of the following chapters 4 and 5 is twofold: (4) an…
Drifting Down the Technologization of Life: Could Choreography-Based Interaction Design Support us in Engaging with the World and our Embodied Living?
2013
The development of interactive technology is often based on the assumption of need to reduce the physical action and cognitive load of the user. However, recent conceptualizations, supported by research in various fields of science, emphasize human physical action in cognitive processes and knowledge formation. In fact, physical and closely related imaginary movement can be seen as the quintessence of humanity. Acknowledging this should imply a new approach to the design of interactive technology. In the current study, we propose a choreographic approach for shifting the focal point of interaction design to the aspects of human activity and movement within a technologized context. Hence, th…
Fiktiiviset reseptit ja mahdottomat ateriat kirjallisen komiikan lajina

Fictitious recipes, impossible meals: a subgenre of comical literature The article looks into ctitious and imaginative food recipes and comical potentiality of such food related text types as listings of ingredients, foodstuffs, dishes, or portions. The focus is on imaginary, fantastic, and impossible meals and recipes: portions that could not be implemented in the real world. The recipe as a form is covered from genre-theoretical, narratological, poetic and procedural perspectives. The special point of reference is experimental literature and its interests in literary forms, rules, constraints, and procedures − the terms that could be used to define also culinary recipes as codes or script…
On the divide between animate and inanimate
2015
Vitalism was abandoned already for a long time ago, yet the impression that animate beings differ in some fundamental way from inanimate objects continues to thrive. Here, we argue that scale free patterns, found throughout nature, present convincing evidence that this demarcation is only imaginary. Therefore, all systems ought to be regarded alike, i.e., all are consuming free energy in least time. This way evolutionary processes can be understood as a series of changes from one state to another, so that flows of energy themselves naturally select those ways and means, such as species and societies or gadgets and galaxies to consume free energy in the least time in quest of attaining therm…
Neogeografia. Per un nuovo immaginario terrestre
2019
Che senso ha fare geografia oggi, in un’epoca in cui il globo è stato esplorato palmo a palmo e le mappe sono disegnate da satelliti e software? Che importanza ha inventarsi un’immagine della Terra in mezzo ai guasti del clima e alla dissoluzione ambientale? Che cosa possono insegnare alla geografia contemporanea un racconto di mare in latino del X secolo, le canzoni di gesta antico francesi, i diari di bordo del capitano Cartier, la Liguria di Montale, l’India di Moravia e Pasolini, la costa bretone di Kenneth White? Neogeografia è un’esplorazione estrema che mira a un duplice cambio di paradigma: ripensare l’epistemologia della geografia e analizzare i testi come altrettanti laboratori di…
