Quantum effects in the collective light scattering by coherent atomic recoil in a Bose-Einstein condensate [PDF]

open access: yes, 2001
We extend the semiclassical model of the collective atomic recoil laser (CARL) to include the quantum mechanical description of the center-of-mass motion of the atoms in a Bose-Einstein condensate (BEC).

Photocatalytic Oxygen Evolution with Prussian Blue Coated ZnO Origami Core-Shell Nanostructures. [PDF]

open access: yesChemphyschem
Prussian Blue and its derivative hold significant potential for photocatalytic oxygen evolution. IN this contribution the photocatalytic oxygen evolution reaction (OER) was characterized using a hybrid catalyst consisting of Prussian Blue coated ZnO nanostructures. The resulting heterojunction, which was characterized both structurally and functionally,

Nonminimal Couplings in the Early Universe: Multifield Models of Inflation and the Latest Observations [PDF]

open access: yes, 2016
Models of cosmic inflation suggest that our universe underwent an early phase of accelerated expansion, driven by the dynamics of one or more scalar fields.

Carl Einstein y el umbral heurístico de la pintura

open access: yesDaimon, 2013
El interés de la filosofía por la pintura es una constante que encuentra especial intensidad en la obra de Merleau-Ponty, Zambrano, Deleuze o Marion. Mayor fuerza presenta, con todo, en los escritos del teórico alemán Carl Einstein (1885-1940), autor de ...

A sobrevivência da estátua

open access: yesBoletim de Pesquisa NELIC, 2020
No poema de Manuel Bandeira o cacto é uma estátua. Essa estátua tomba e interrompe a vida na cidade. Na morte o cacto se historiciza e, nesse sentido, ganha vida.

Effect of heuristics on serendipity in path-based storytelling with linked data [PDF]

open access: yes, 2016
Path-based storytelling with Linked Data on the Web provides users the ability to discover concepts in an entertaining and educational way. Given a query context, many state-of-the-art pathfinding approaches aim at telling a story that coincides with the

Post-stroke epileptogenesis is associated with altered intrinsic properties of hippocampal pyramidal neurons leading to increased theta resonance

open access: yesNeurobiology of Disease, 2021
Brain insults like stroke, trauma or infections often lead to blood-brain barrier-dysfunction (BBBd) frequently resulting into epileptogenesis. Affected patients suffer from seizures and cognitive comorbidities that are potentially linked to altered ...

Plan des formes, plan des forces

open access: yesSocio-anthropologie, 2017
Between Negerplastik (1915) and Afrikanische Plastik (1921), there is a shift in Carl Einstein’s perspective. This author, who was one of the first thinkers on African art and its scope for the avant-gardes, avoids a disembedded aesthetic approach ...

Superradiant light scattering from a moving Bose-Einstein condensate [PDF]

open access: yes, 2003
We investigate the interaction of a moving BEC with a far detuned laser beam. Superradiant Rayleigh scattering arises from the spontaneous formation of a matter-wave grating due to the interference of two wavepackets with different momenta. The system is

Effect of intraoperative PEEP with recruitment maneuvers on the occurrence of postoperative pulmonary complications during general anesthesia––protocol for Bayesian analysis of three randomized clinical trials of intraoperative ventilation [version 1; peer review: 2 approved]

open access: yesF1000Research, 2022
Background: Using the frequentist approach, a recent meta–analysis of three randomized clinical trials in patients undergoing intraoperative ventilation during general anesthesia for major surgery failed to show the benefit of ventilation that uses high ...
