Tressage de sensation et hypersensibilité dans la poésie keatsienne
2020
La synesthesie, phenomene neurologique aujourd’hui reconnu, suscite depuis plusieurs annees un regain d’interet dans le monde scientifique comme le confirme la parution, en 2011, de l’article d’Herve-Pierre Lambert « La synesthesie. Vues de l’interieur », dans lequel l’auteur repertorie les evolutions historiques de l’etude du concept. En neuropsychologie, la synesthesie est un trouble de la perception sensorielle qui produit des associations previsibles, mais involontaires, entre differents ...
Toward a better understanding of in-field weed regulation by carabid beetles, and their functional characteristics, in European arable landscapes
2019
For future arable agriculture, there is a need for more sustainable methods to manage weeds that are less reliant on herbicides and maintain food production. Control of weeds by natural enemies is an agro-ecological alternative to reduce the use of herbicides. While strong evidence points to carabid beetles exerting a regulatory effect on certain weed species, it is difficult to predict whether a particular assemblage of carabid species or functional groups will drive the function of weed seed predation in field conditions. There are also uncertainties about which key local and landscape-scale factors affect the function of weed seed predation, and the functional characteristics of carabid …
Experimental analysis of the potential validity of Lorenzini’s hypothesis to treat COVID-19 patients
2021
The present research was aimed at testing the potential validity of Lorenzini’s hypothesis against Covid-19, based on the use of far UV-C rays directly on the patient’s ill lungs, so to significantly reduce the virus presence and with it the interstitial pneumonia, the cause of most deaths. Not having had the chance to experiment directly on the SARS-CoV-2, we shifted to a plant virus called TSWV, which has some common characteristics with SARS-CoV-2, so making our tests significant. The virus was suitably utilized so to affect an opportune range of pepper plants, after a treatment with 2 UV-C lamps, of which just one spreading far UV-C rays. Results showed that the effect of a quick exposi…

Multisensory texture exploration at the tip of the pen
2016
A tool for the multisensory stylus-based exploration of virtual textures was used to investigate how different feedback modalities (static or dynamically deformed images, vibration, sound) affect exploratory gestures. To this end, we ran an experiment where participants had to steer a path with the stylus through a curved corridor on the surface of a graphic tablet/display, and we measured steering time, dispersion of trajectories, and applied force. Despite the variety of subjective impressions elicited by the different feedback conditions, we found that only nonvisual feedback induced significant variations in trajectories and an increase in movement time. In a post-experiment, using a pa…
A Universal Length-Dependent Vibrational Mode in Graphene Nanoribbons
2019
Graphene nanoribbons (GNRs) have attracted considerable interest as their atomically tunable structure makes them promising candidates for future electronic devices. However, obtaining detailed information about the length of GNRs has been challenging and typically relies on low-temperature scanning tunneling microscopy. Such methods are ill-suited for practical device application and characterization. In contrast, Raman spectroscopy is a sensitive method for the characterization of GNRs, in particular for investigating their width and structure. Here, we report on a length-dependent, Raman active low-energy vibrational mode that is present in atomically precise, bottom-up synthesized armch…
The evolution of Military Health in Valencia during the Spanish Civil War (1936-1939)
2011
Antecedentes y objetivos: Tras la insurrección militar del 18 de julio de 1936 el Ejército de la República quedó parcialmente desarticulado, resultando afectada la Sanidad Militar. En el caso de Valencia, ésta fue asumida rápidamente por el Comité Sanitario Popular, un organismo revolucionario que lideró la respuesta sanitaria de Valencia a la Guerra Civil. Posteriormente, el Gobierno Republicano procedió a recuperar el poder a través de medidas de carácter centralizador, como fue la militarización de algunos hospitales. Fue entonces cuando volvió a articularse una auténtica Sanidad Militar. El objetivo de este trabajo es estudiar la evolución de la Sanidad Militar en Valencia, una de las z…
Health coverage for a retreating army: a Medical Captain’s action during the Maestrazgo campaign (April-July 1938).
2012
espanolAntecedentes y objetivos: Tras la entrada definitiva de las tropas del general Franco en la ciudad de Teruel en febrero de 1938 se inicio la retirada progresiva del Ejercito de Maniobra de la republica. El rapido avance de las fuerzas nacionales hacia el Mediterraneo marco las caracteristicas de la cobertura sanitaria militar. El objetivo de este trabajo es realizar una aproximacion a la Sanidad del Ejercito republicano durante su retirada por el Maestrazgo castellonense, que tuvo lugar entre abril y julio de 1938 en el contexto de la Guerra Civil Espanola (1936-1939). Material y metodos: Hemos utilizado una fuente de gran valor historico, como es el testimonio oral de un Capitan Med…
The Philae lander mission and science overview.
2017
The Philae lander accomplished the first soft landing and the first scientific experiments of a human-made spacecraft on the surface of a comet. Planned, expected and unexpected activities and events happened during the descent, the touch-downs, the hopping across and the stay and operations on the surface. The key results were obtained during 12–14 November 2014, at 3 AU from the Sun, during the 63 h long period of the descent and of the first science sequence on the surface. Thereafter, Philae went into hibernation, waking up again in late April 2015 with subsequent communication periods with Earth (via the orbiter), too short to enable new scientific activities. The science return of the…
Learning automata based energy-efficient AI hardware design for IoT applications
2020
Energy efficiency continues to be the core design challenge for artificial intelligence (AI) hardware designers. In this paper, we propose a new AI hardware architecture targeting Internet of Things applications. The architecture is founded on the principle of learning automata, defined using propositional logic. The logic-based underpinning enables low-energy footprints as well as high learning accuracy during training and inference, which are crucial requirements for efficient AI with long operating life. We present the first insights into this new architecture in the form of a custom-designed integrated circuit for pervasive applications. Fundamental to this circuit is systematic encodin…
