Malvinas ¿campo o línea de berma?
Boletín de Historia Argentina y Americana Dr. Emilio Ravignani, 2023 A partir de “Un recorrido personal. Reflexiones y propuestas a cuarenta años de la Guerra de Malvinas”, el autor de este artículo toma una de las tantas postas planteadas en el texto de Federico Lorenz para profundizar sobre un aspecto: ¿es posible ...

Space-time correlations within pairs produced during inflation, a wave-packet analysis
, 2003 In homogeneous universes the propagation of quantum fields gives rise to pair creation of quanta with opposite momenta. When computing expectation values of operators, the correlations between these quanta are averaged out and no space-time structure is ...

An improved discretization of Schrodinger-like radial equations [PDF]
, 2018 A new discretization of the radial equations that appear in the solution of separable second order partial differential equations with some rotational symmetry (as the Schrodinger equation in a central potential) is presented.

Spectroscopic Evidence of Edge‐Localized States in an Antiferromagnet Topological Insulator NdBi
Advanced Science, EarlyView.Using spin‐polarized scanning tunneling microscopy (STM) in conjunction with quasiparticle interference, we successfully identify distinct signatures of the ferromagnetic and antiferromagnetic terminations in NdBi, a rare‐earth monopnictide exhibiting non‐trivial topology and magnetism. We demonstrate that step edges on ferromagnetic surfaces host well‐

Diseño y complejidad. La expansión del campo del diseño
Area, 2017 Si el diseño tal y como lo conocemos hoy es hijo de la modernidad, el debate modernidad-posmodernidad ¿ha influido en los discursos de esta disciplina? ¿Se reconfigura y expande su campo?

Decoherence and entropy of primordial fluctuations II. The entropy budget
, 2008 We calculate the entropy of adiabatic perturbations associated with a truncation of the hierarchy of Green functions at the first non trivial level, i.e. in a self-consistent Gaussian approximation.

Consumer Valuation of Meat Alternatives and Labeling Policies: A Comparative Perspective
Applied Economic Perspectives and Policy, EarlyView.ABSTRACT This study investigates and compares US consumer perceptions and the impact of environmental, human health, and animal welfare information related to conventional meat on preferences for meat alternatives and labeling policies. Using the best–worst scaling method across 10 different burger alternatives, our results show that the meat burger is

Decoherence and entropy of primordial fluctuations. I: Formalism and interpretation
, 2008 We propose an operational definition of the entropy of cosmological perturbations based on a truncation of the hierarchy of Green functions. The value of the entropy is unambiguous despite gauge invariance and the renormalization procedure.
