Search for gamma ray bursts with the ARGO-YBJ detector in scaler mode
2009
We report on the search for Gamma Ray Bursts (GRBs) in the energy range 1-100 GeV in coincidence with the prompt emission detected by satellites using the Astrophysical Radiation with Ground-based Observatory at YangBaJing (ARGO-YBJ) air shower detector. Thanks to its mountain location (Yangbajing, Tibet, P.R. China, 4300 m a.s.l.), active surface (about 6700 m**2 of Resistive Plate Chambers), and large field of view (about 2 sr, limited only by the atmospheric absorption), the ARGO-YBJ air shower detector is particularly suitable for the detection of unpredictable and short duration events such as GRBs. The search is carried out using the "single particle technique", i.e. counting all the …
Size of the dark side of the solar neutrino parameter space
2000
We present an analysis of the MSW neutrino oscillation solutions of the solar neutrino problem in the framework of two-neutrino mixing in the enlarged parameter space $(\ensuremath{\Delta}{m}^{2},{\mathrm{tan}}^{2}\ensuremath{\theta})$ with $\ensuremath{\theta}\ensuremath{\in}(0,\ensuremath{\pi}/2).$ Recently, it was pointed out that the allowed region of parameters from a fit to the measured total rates can extend to values $\ensuremath{\theta}g~\ensuremath{\pi}/4$ (the so-called ``dark side'') when higher confidence levels are allowed. The purpose of this Rapid Communication is to reanalyze the problem, including all the solar neutrino data available, to discuss the dependence on the stat…
10.2 Discrete Symmetries
2008
1. The asymmetry of the zenith angle distribution of νμ of Super-Kamiokande is the direct evidence of νμ oscillations. 2. The first oscillation minimum was observed in the L/E distribution using the high resolution L/E sample of Super-Kamiokande. It confirms that the distortion of the zenith angle distribution is really due to neutrino oscillations and excludes other hypotheses such as neutrino decay and decoherence model. 3. A search for charged current (CC) interaction of ντ shows a 2.4σ excess of signal and the observed number of events is consistent with the expectation. 4. No indication of νe oscillation is observed so far in atmospheric neutrinos.
La diplomatie humanitaire ou l’impact du numérique sur la mobilisation
2018
State or sovereign nation diplomacy, which had long been an arena reserved for politicians, has never stopped evolving and changing. New actors, including non-state actors, have emerged on the scene. Further, modern means and methods of communication have played a role in revolutionizing diplomatic activity. In this context of internationalization and globalization, something completely novel has grown up in this field: non-governmental humanitarian diplomacy 2.0. The initiatives undertaken by these non-state organizations and their proven success demonstrate that new practices, new modes of communication (especially via the Internet), and new forms of discourse are being constructed. The h…
Influence of solar and sensor angles on chlorophyll estimation for geostationary ocean color imager
2012
The impact of the solar and sensor angles on band-ratio chlorophyll concentration (Chl) estimation in Case 1 waters (open ocean) is analyzed in this work. The error range of Chl estimation due to angular variation is evaluated. The radiative transfer code Hydrolight is used for remote sensing reflectance simulation for 20 spectral bands. OC4v4 algorithm is used for Chl estimation. The results indicate that the error range of Chl estimation is between -41.91% and +46.15% when Chl range is from 0.0425 mg/m 3 to 10.6685 mg/m 3 and the solar and sensor zenith angles vary between 0 and 80°. This study provides a reference to determine the effective observation area of a future multispectral or h…
Cultural institutions as agents of urban and community regeneration in the (post-)pandemic city. The case of the «Laboratorio Zen Insieme» in Palermo
2022
Although all cities in the world have been affected by the COVID-19 pandemic, its impacts on the territories, yet to be understood, are unevenly distributed, revealing extremely varied imbalances depending on the places. However, it is clear that the virus and its variants have aggravated pre-existing socio-spatial inequalities, creating new ones and bringing attention back to those implications between space, planning, public health and citizenship that are at the origins of contemporary urbanism. In a reference framework in which the crisis is globalized but unequal and in the absence of a welfare system capable of responding to the urgencies of the most marginalized social contexts and g…
Final results of the European Advanced Renal Cell Carcinoma Sorafenib (EU-ARCCS) expanded-access study: a large open-label study in diverse community…
2011
Background The European Advanced Renal Cell Carcinoma Sorafenib (EU-ARCCS) expanded-access study provided sorafenib to advanced renal cell carcinoma (RCC) patients in whom previous systemic therapy had failed. The study assessed the safety and use of sorafenib for the treatment of advanced RCC in a large community-based patient population across 11 countries in Europe. Patients and methods EU-ARCCS was a single-arm, open-label trial of sorafenib in advanced RCC patients. End points included safety, time to progression, progression-free survival (PFS), and disease control rate (DCR). Subgroup analyses included age, Eastern Cooperative Oncology Group performance status, histology, prior thera…
Sorafenib for recurrence of hepatocellular carcinoma after liver transplantation.
2011
Abstract Background Recurrence of hepatocellular carcinoma after orthotopic liver transplantation not amenable to surgical approaches is associated with poor outcome. Aims Retrospective evaluation of the safety and efficacy of sorafenib in patients with post-transplant hepatocellular carcinoma recurrence. Methods Patients with post-transplant hepatocellular carcinoma recurrence were treated with sorafenib. Adverse events were assessed using National Cancer Institute Common Toxicity Criteria of AEs version 3.0, tumour response was evaluated according to Response Evaluation Criteria in Solid Tumours. Results First-line therapy after recurrence was surgery ( n = 6), radiation therapy ( n = 1…
Management of cirrhotic patients with hepatocellular carcinoma treated with sorafenib
2011
Sorafenib (Nexavar®, Bayer), a multi-targeted tyrosine kinase inhibitor, was the first systemic agent that demonstrated a significant improvement in the overall survival in patients with advanced hepatocellular carcinoma and well-preserved liver function. This drug is now recommended in patients with advanced hepatocellular carcinoma as first-line therapy and for patients not suitable for locoregional treatment. This brief article, produced by a multidisciplinary panel including specialists in gastroenterology and oncology, provides an overview of the major issues related to systemic treatment of hepatocellular carcinoma with sorafenib, including staging and prognostic strategies, assessmen…
High activity of sorafenib in FLT3-ITD-positive acute myeloid leukemia synergizes with allo-immune effects to induce sustained responses.
2012
Preliminary evidence suggests that the multikinase inhibitor sorafenib has clinical activity in FLT3-ITD-positive (FLT3-ITD) acute myeloid leukemia (AML). However, the quality and sustainability of achievable remissions and clinical variables that influence the outcome of sorafenib monotherapy are largely undefined. To address these questions, we evaluated sorafenib monotherapy in 65 FLT3-ITD AML patients treated at 23 centers. All but two patients had relapsed or were chemotherapy-refractory after a median of three prior chemotherapy cycles. Twenty-nine patients (45%) had undergone prior allogeneic stem cell transplantation (allo-SCT). The documented best responses were: hematological remi…
