    Background: The connection between corticotherapy and neuropsychiatric symptoms is widely known, being one of the first questions we need to assess when presenting with first episode psychiatric symptoms or confusional state. Aims: To date, data on cases related to inhaled corticotherapy and neuropsychiatric effects is scarce. In this paper we describe a rare case in a young woman. Methods: The clinical case presented led us to try to understand the data published on the subject in order to discuss it in greater length. Results and Conclusions: We present and discuss a 27-year-old patient’s case, with no previous psychiatric disease, who was admitted to our Psychiatric ward after the onset of severe acute behavioural disturbance characterized by aggressiveness, visual and auditory hallucinatory activity, misidentification and altered conscience status. It was later found that seven days earlier she had been prescribed inhaled corticotherapy for a minor respiratory infection. A few days after corticotherapy withdrawal, the clinical symptoms improved significantly.info:eu-repo/semantics/publishedVersio

    General scalar products in the arbitrary six-vertex model

    Full text link
    In this work we use the algebraic Bethe ansatz to derive the general scalar product in the six-vertex model for generic Boltzmann weights. We performed this calculation using only the unitarity property, the Yang-Baxter algebra and the Yang-Baxter equation. We have derived a recurrence relation for the scalar product. The solution of this relation was written in terms of the domain wall partition functions. By its turn, these partition functions were also obtained for generic Boltzmann weights, which provided us with an explicit expression for the general scalar product.Comment: 24 page

    Corporate social responsibility and circular economy from the perspective of consumers: A cross-cultural analysis in the cosmetic industry

    Corporate social responsibility (CSR) and circular economy (CE) have assumed considerable importance in the efforts for sustainable development. However, some consumers do not positively respond to CSR and CE activities, and few studies have analyzed the consumers' perspective about the topics. This study investigates consumer knowledge and perception about CSR and CE and their willingness to pay (WTP) for products from companies that follow these concepts, examining differences according to demographic characteristics. We carried out a survey with 302 Brazilian and Italian consumers of cosmetic products. Our results show that most consumers have a low understanding of CSR and CE and a low perception of the socio-environmental initiatives of companies that follow CSR and CE concepts. Nevertheless, most consumers show WTP for products from companies that follow these concepts. We identified demographic variables that allowed us to relate the profile of consumers with their knowledge about CSR and CE and their WTP. We provide insights for companies and policymakers in advancing toward CSR and CE

    Magnetic properties of GdT2T_2Zn20_{20} (T = Fe, Co) investigated by X-ray diffraction and spectroscopy

    We investigate the magnetic and electronic properties of the GdT2T_2Zn20_{20} (TT = Fe and Co) compounds using X-ray resonant magnetic scattering (XRMS), X-ray absorption near-edge structure (XANES) and X-ray magnetic circular dichroism (XMCD) techniques. The XRMS measurements reveal that the GdCo2_2Zn20_{20} compound has a commensurate antiferromagnetic spin structure with a magnetic propagation vector τ\vec{\tau} = (12,12,12)(\frac{1}{2},\frac{1}{2},\frac{1}{2}) below the N\'eel temperature (TNT_N \sim 5.7 K). Only the Gd ions carry a magnetic moment forming an antiferromagnetic structure with magnetic representation Γ6\Gamma_6. For the ferromagnetic GdFe2_2Zn20_{20} compound, an extensive investigation was performed at low temperature and under magnetic field using XANES and XMCD techniques. A strong XMCD signal of about 12.5 %\% and 9.7 %\% is observed below the Curie temperature (TCT_C \sim 85 K) at the Gd-L2L_2 and L3L_3 edges, respectively. In addition, a small magnetic signal of about 0.06 %\% of the jump is recorded at the Zn KK-edge suggesting that the Zn 4pp states are spin polarized by the Gd 5dd extended orbitals

    The Distance to Nova V959 Mon from VLA Imaging

    Determining reliable distances to classical novae is a challenging but crucial step in deriving their ejected masses and explosion energetics. Here we combine radio expansion measurements from the Karl G. Jansky Very Large Array with velocities derived from optical spectra to estimate an expansion parallax for nova V959 Mon, the first nova discovered through its gamma-ray emission. We spatially resolve the nova at frequencies of 4.5-36.5 GHz in nine different imaging epochs. The first five epochs cover the expansion of the ejecta from 2012 October to 2013 January, while the final four epochs span 2014 February to 2014 May. These observations correspond to days 126 through 199 and days 615 through 703 after the first detection of the nova. The images clearly show a non-spherical ejecta geometry. Utilizing ejecta velocities derived from 3D modelling of optical spectroscopy, the radio expansion implies a distance between 0.9 +/- 0.2 and 2.2 +/- 0.4 kpc, with a most probable distance of 1.4 +/- 0.4 kpc. This distance implies a gamma-ray luminosity much less than the prototype gamma-ray-detected nova, V407 Cyg, possibly due to the lack of a red giant companion in the V959 Mon system. V959 Mon also has a much lower gamma-ray luminosity than other classical novae detected in gamma-rays to date, indicating a range of at least a factor of 10 in the gamma-ray luminosities for these explosions.Comment: 11 pages, 8 figures, 3 tables, submitted to ApJ 2015-01-21, under revie

    Coherent Adiabatic Spin Control in the Presence of Charge Noise Using Tailored Pulses

    Full text link
    We study finite-time Landau-Zener transitions at a singlet-triplet level crossing in a GaAs double quantum dot, both experimentally and theoretically. Sweeps across the anticrossing in the high driving speed limit result in oscillations with a small visibility. Here we demonstrate how to increase the oscillation visibility while keeping sweep times shorter than T2* using a tailored pulse with a detuning dependent level velocity. Our results show an improvement of a factor ~2.9 for the oscillation visibility. In particular, we were able to obtain a visibility of ~0.5 for St\"uckelberg oscillations, which demonstrates the creation of an equally weighted superposition of the qubit states.Comment: Related papers at http://pettagroup.princeton.ed
