Synchronizing Two Superconducting Qubits through a Dissipating Resonator
2021
A system consisting of two qubits and a resonator is considered in the presence of different sources of noise, bringing to light the possibility of making the two qubits evolve in a synchronized way. A direct qubit–qubit interaction turns out to be a crucial ingredient, as well as the dissipation processes involving the resonator. The detrimental role of the local dephasing of the qubits is also taken into account.
Intracranial Venous Alteration in Patients With Aneurysmal Subarachnoid Hemorrhage: Protocol for the Prospective and Observational SAH Multicenter St…
2022
BackgroundArterial vasospasm has been ascribed as the responsible etiology of delayed cerebral infarction in patients with aneurysmal subarachnoid hemorrhage (aSAH), but other neurovascular structures may be involved. We present the protocol for a multicenter, prospective, observational study focused on analyzing morphological changes in cerebral veins of patients with aSAH.Methods and AnalysisIn a retrospective arm, we will collect head arterial and venous CT angiograms (CTA) of 50 patients with aSAH and 50 matching healthy controls at days 0–2 and 7–10, comparing morphological venous changes. A multicenter prospective observational study will follow. Patients aged ≥18 years of any gender …
Réponses du d13C au forçage astronomique dans divers contextes de production carbonatée : le cas du Valanginien du Sud-Est de la France
2018
International audience; Le d13C est un outil fréquemment utilisé pour établir des échelles de temps astronomiques en milieu (hémi-) pélagique. Pourtant le lien entre d13C et forçage astronomique n’est pas toujours clair, tant les sources de carbone sont multiples. Nous avons comparé le d13C à la susceptibilité magnétique (SM) et aux cortèges argileux dans les séries marno-calcaires du Valanginien du Bassin Vocontien (SE France). Ces deux signaux sont fréquemment utilisés pour détecter un forçage astronomique dans les alternances marno-calcaires. Deux intervalles de 400 ka (correspondant à un cycle de grande excentricité) ont été ciblés, l’un avant la crise des producteurs carbonatés associé…
Evoluzione tipologica e tecnologica dei sistemi di abitazione per l'emergenza _ Typological and technological evolution of housing systems for emerge…
2017
Le tipologie di abitazione temporanea oggi utilizzate in caso di emergenza si possono ricondurre a due sistemi strutturali fondamentali: il sistema ad involucro flessibile ed il sistema ad involucro rigido. Da questi deriva un sistema misto in cui elementi flessibili si integrano ad elementi rigidi, generando soluzioni particolarmente interessanti sia dal punto di vista tecnologico sia formale. Ai sistemi flessibili appartiene la tenda, insieme a tutte quelle strutture leggere, estensibili e/o gonfiabili, quali strutture a pantografo, pneumatiche o, tensostruttu-re. Ai sistemi rigidi si fa risalire la casa, da cui derivano il container ed il prefab-bricato, ma anche la roulotte ed il camper…
Alternativas a las penas privativas de libertad de corta duración. Especial referencia a la suspensión y sustitución de la pena
2017
Desde hace siglos, el elenco de penas previsto en los distintos Códigos Penales peca de excesivamente básico y las posibles alternativas a la pena por excelencia, la prisión, son de igual modo parcas, sin que ello parezca haber preocupado demasiado al legislador. Nuestro Código Penal regula dos alternativas principales al cumplimiento de las penas privativas de libertad, las instituciones de la suspensión y la sustitución, a las que dedica, básicamente, los artículos 80 a 87 y el 89, habiendo sido derogado el 88, dedicado a la sustitución ordinaria, que ahora pasa a considerarse una modalidad de suspensión. La razón de ser de estas alternativas es tratar de evitar el efecto corruptor de la …
Using altered states of consciousness in improvisational music therapy : the potential of resonance frequency breathing
2018
Improvisational music therapy is a type of creative arts therapy in which clients are encouraged to express themselves through the symbolic and non-verbal medium of music, by creating free music improvisations together with the therapist. The present research aims at investigating whether the efficacy of this method can be further enhanced by purposefully accessing the ego-quieting properties of altered states of consciousness. This work proceeds in three main steps. First, the notions of consciousness and its alteration are examined and reformulated, resulting in a more comprehensive theoretical model. Then, existing methods for inducing altered states of consciousness are evaluated in ter…

A Method of Conversion of some Coefficient Inverse Parabolic Problems to a Unified Type of Integral-Differential Equation
2011
Coefficient inverse problems are reformulated to a unified integral differential equation. The presented method of conversion of the considered inverse problems to a unified Volterra integral-differential equation gives an opportunity to distribute the acquired results also to analogous inverse problems for non-linear parabolic equations of different types.
A Leibniz variety with almost polynomial growth
2005
Abstract Let F be a field of characteristic zero. In this paper we study the variety of Leibniz algebras V ˜ 1 defined by the identity y 1 ( y 2 y 3 ) ( y 4 y 5 ) ≡ 0 . We give a complete description of the space of multilinear identities in the language of Young diagrams through the representation theory of the symmetric group. As an outcome we show that the variety V ˜ 1 has almost polynomial growth, i.e., the sequence of codimensions of V ˜ 1 cannot be bounded by any polynomial function but any proper subvariety of V ˜ 1 as polynomial growth.
Synchrotron x-ray transmission measurements and modeling of filters investigated for Athena
2020
International audience; Advanced Telescope for High-Energy Astrophysics is a large-class astrophysics space mission selected by the European Space Agency to study the theme "Hot and Energetic Universe." The mission essentially consists of a large effective area x-ray telescope and two detectors: the X-ray Integral Field Unit (X-IFU) and the Wide Field Imager (WFI). Both instruments require filters to shield from out-of-band radiation while providing high transparency to x-rays. The mission is presently in phase B; thus, to consolidate the preliminary design, investigated filter materials need to be properly characterized by experimental test campaigns. We report results from high-resolution…
