Abstract

Abstract KM3NeT/ORCA is a water Cherenkov neutrino detector under construction and anchored at the bottom of the Mediterranean Sea. The detector is designed to study oscillations of atmospheric neutrinos and determine the neutrino mass ordering. This paper focuses on an initial configuration of ORCA, referred to as ORCA6, which comprises six out of the foreseen 115 detection units of photo-sensors. A high-purity neutrino sample was extracted, corresponding to an exposure of 433 kton-years. The sample of 5828 neutrino candidates is analysed following a binned log-likelihood method in the reconstructed energy and cosine of the zenith angle. The atmospheric oscillation parameters are measured to be sin 2 θ 23 = 0.51 − 0.05 + 0.04 $$ {\sin}^2{\theta}_{23}={0.51}_{-0.05}^{+0.04} $$ , and Δ m 31 2 = 2.18 − 0.35 + 0.25 × 10 − 3 eV 2 ∪ − 2.25 − 1.76 × 10 − 3 $$ \Delta {m}_{31}^2={2.18}_{-0.35}^{+0.25}\times {10}^{-3}{\textrm{eV}}^2\cup \left\{-2.25,-1.76\right\}\times {10}^{-3} $$ eV2 at 68% CL. The inverted neutrino mass ordering hypothesis is disfavoured with a p-value of 0.25.

Abstract

Abstract The KM3NeT/ARCA neutrino detector is currently under construction at 3500 m depth offshore Capo Passero, Sicily, in the Mediterranean Sea. The main science objectives are the detection of high-energy cosmic neutrinos and the discovery of their sources. Simulations were conducted for the full KM3NeT/ARCA detector, instrumenting a volume of 1 km $$^3$$ 3 , to estimate the sensitivity and discovery potential to point-like neutrino sources. This paper covers the reconstruction of track- and shower-like signatures, as well as the criteria employed for neutrino event selection. With an angular resolution below 0.1 $$^\circ $$ ∘ for tracks and under 2 $$^\circ $$ ∘ for showers, the sensitivity to point-like neutrino sources surpasses existing observed limits across the entire sky.

Abstract

Abstract The measurement of the flux of muons produced in cosmic ray air showers is essential for the study of primary cosmic rays. Such measurements are important in extensive air shower detectors to assess the energy spectrum and the chemical composition of the cosmic ray flux, complementary to the information provided by fluorescence detectors. Detailed simulations of the cosmic ray air showers are carried out, using codes such as CORSIKA, to estimate the muon flux at sea level. These simulations are based on the choice of hadronic interaction models, for which improvements have been implemented in the post-LHC era. In this work, a deficit in simulations that use state-of-the-art QCD models with respect to the measurement deep underwater with the KM3NeT neutrino detectors is reported. The KM3NeT/ARCA and KM3NeT/ORCA neutrino telescopes are sensitive to TeV muons originating mostly from primary cosmic rays with energies around 10 TeV. The predictions of state-of-the-art QCD models show that the deficit with respect to the data is constant in zenith angle; no dependency on the water overburden is observed. The observed deficit at a depth of several kilometres is compatible with the deficit seen in the comparison of the simulations and measurements at sea level.

Abstract

Abstract This article reports the first observation of the Moon and the Sun shadows in the sky distribution of cosmic-ray induced muons measured by the KM3NeT/ORCA detector. The analysed data-taking period spans from February 2020 to November 2021, when the detector had 6 Detection Units deployed at the bottom of the Mediterranean Sea, each composed of 18 Digital Optical Modules. The shadows induced by the Moon and the Sun were detected at their nominal position with a statistical significance of 4.2 $$\sigma $$ σ and 6.2 $$\sigma $$ σ , and an angular resolution of $$\sigma _{res}=0.49^\circ $$ σ res = 0 . 49 ∘ and $$\sigma _{res}=0.66^\circ $$ σ res = 0 . 66 ∘ , respectively, consistent with the prediction of $$0.53^\circ $$ 0 . 53 ∘ from simulations. This early result confirms the effectiveness of the detector calibration, in time, position and orientation and the accuracy of the event direction reconstruction. This also demonstrates the performance and the competitiveness of the detector in terms of pointing accuracy and angular resolution.

Abstract

Abstract In the era of precision measurements of the neutrino oscillation parameters, upcoming neutrino experiments will also be sensitive to physics beyond the Standard Model. KM3NeT/ORCA is a neutrino detector optimised for measuring atmospheric neutrinos from a few GeV to around 100 GeV. In this paper, the sensitivity of the KM3NeT/ORCA detector to neutrino decay has been explored. A three-flavour neutrino oscillation scenario, where the third neutrino mass state ν 3 decays into an invisible state, e.g. a sterile neutrino, is considered. We find that KM3NeT/ORCA would be sensitive to invisible neutrino decays with 1/α 3 = τ 3 /m 3 < 180 ps/eV at 90% confidence level, assuming true normal ordering. Finally, the impact of neutrino decay on the precision of KM3NeT/ORCA measurements for θ 23, Δ m 31 2 $$ \Delta {m}_{31}^2 $$ and mass ordering have been studied. No significant effect of neutrino decay on the sensitivity to these measurements has been found.

Abstract

Abstract The KM3NeT research infrastructure is unconstruction in the Mediterranean Sea. KM3NeT will study atmospheric and astrophysical neutrinos with two multi-purpose neutrino detectors, ARCA and ORCA, primarily aimed at GeV–PeV neutrinos. Thanks to the multi-photomultiplier tube design of the digital optical modules, KM3NeT is capable of detecting the neutrino burst from a Galactic or near-Galactic core-collapse supernova. This potential is already exploitable with the first detection units deployed in the sea. This paper describes the real-time implementation of the supernova neutrino search, operating on the two KM3NeT detectors since the first months of 2019. A quasi-online astronomy analysis is introduced to study the time profile of the detected neutrinos for especially significant events. The mechanism of generation and distribution of alerts, as well as the integration into the SNEWS and SNEWS 2.0 global alert systems, are described. The approach for the follow-up of external alerts with a search for a neutrino excess in the archival data is defined. Finally, an overview of the current detector capabilities and a report after the first two years of operation are given.

Abstract

Abstract This article presents the potential of a combined analysis of the JUNO and KM3NeT/ORCA experiments to determine the neutrino mass ordering. This combination is particularly interesting as it significantly boosts the potential of either detector, beyond simply adding their neutrino mass ordering sensitivities, by removing a degeneracy in the determination of ∆ m 31 2 $$ {m}_{31}^2 $$ between the two experiments when assuming the wrong ordering. The study is based on the latest projected performances for JUNO, and on simulation tools using a full Monte Carlo approach to the KM3NeT/ORCA response with a careful assessment of its energy systematics. From this analysis, a 5σ determination of the neutrino mass ordering is expected after 6 years of joint data taking for any value of the oscillation parameters. This sensitivity would be achieved after only 2 years of joint data taking assuming the current global best-fit values for those parameters for normal ordering.

Abstract

Abstract The next generation of water Cherenkov neutrino telescopes in the Mediterranean Sea are under construction offshore France (KM3NeT/ORCA) and Sicily (KM3NeT/ARCA). The KM3NeT/ORCA detector features an energy detection threshold which allows to collect atmospheric neutrinos to study flavour oscillation. This paper reports the KM3NeT/ORCA sensitivity to this phenomenon. The event reconstruction, selection and classification are described. The sensitivity to determine the neutrino mass ordering was evaluated and found to be 4.4 $$\sigma $$ σ if the true ordering is normal and 2.3 $$\sigma $$ σ if inverted, after 3 years of data taking. The precision to measure $$\varDelta m^2_{32}$$ Δ m 32 2 and $$\theta _{23}$$ θ 23 were also estimated and found to be $$85 . 10^{-6}~{\mathrm{eV}^{2}}$$ 85 . 10 - 6 eV 2 and $$(^{+1.9}_{-3.1})^{\circ }$$ ( - 3.1 + 1.9 ) ∘ for normal neutrino mass ordering and, $$75 . 10^{-6}~{\mathrm{eV}^{2}}$$ 75 . 10 - 6 eV 2 and $$(^{+2.0}_{-7.0})^{\circ }$$ ( - 7.0 + 2.0 ) ∘ for inverted ordering. Finally, a unitarity test of the leptonic mixing matrix by measuring the rate of tau neutrinos is described. Three years of data taking were found to be sufficient to exclude event rate variations larger than 20% at $$3\sigma $$ 3 σ level.

Abstract

Abstract KM3NeT/ORCA is a next-generation neutrino telescope optimised for atmospheric neutrino oscillations studies. In this paper, the sensitivity of ORCA to the presence of a light sterile neutrino in a 3+1 model is presented. After three years of data taking, ORCA will be able to probe the active-sterile mixing angles θ 14, θ 24, θ 34 and the effective angle θ μe , over a broad range of mass squared difference ∆ m 41 2 $$ \Delta {m}_{41}^2 $$ ∼ [10 −5 , 10] eV2, allowing to test the eV-mass sterile neutrino hypothesis as the origin of short baseline anomalies, as well as probing the hypothesis of a very light sterile neutrino, not yet constrained by cosmology. ORCA will be able to explore a relevant fraction of the parameter space not yet reached by present measurements.

Abstract

Abstract The KM3NeT research infrastructure is under construction in the Mediterranean Sea. It consists of two water Cherenkov neutrino detectors, ARCA and ORCA, aimed at neutrino astrophysics and oscillation research, respectively. Instrumenting a large volume of sea water with $$\sim {6200}$$ ∼ 6200 optical modules comprising a total of $$\sim {200{,}000}$$ ∼ 200 , 000 photomultiplier tubes, KM3NeT will achieve sensitivity to $$\sim {10} \ \mathrm{MeV}$$ ∼ 10 MeV neutrinos from Galactic and near-Galactic core-collapse supernovae through the observation of coincident hits in photomultipliers above the background. In this paper, the sensitivity of KM3NeT to a supernova explosion is estimated from detailed analyses of background data from the first KM3NeT detection units and simulations of the neutrino signal. The KM3NeT observational horizon (for a $$5\,\sigma $$ 5 σ discovery) covers essentially the Milky-Way and for the most optimistic model, extends to the Small Magellanic Cloud ( $$\sim {60} \ \mathrm{kpc}$$ ∼ 60 kpc ). Detailed studies of the time profile of the neutrino signal allow assessment of the KM3NeT capability to determine the arrival time of the neutrino burst with a few milliseconds precision for sources up to 5–8 kpc away, and detecting the peculiar signature of the standing accretion shock instability if the core-collapse supernova explosion happens closer than 3–5 kpc, depending on the progenitor mass. KM3NeT’s capability to measure the neutrino flux spectral parameters is also presented.

Abstract

Abstract KM3NeT is a research infrastructure located in the Mediterranean Sea, that will consist of two deep-sea Cherenkov neutrino detectors. With one detector (ARCA), the KM3NeT Collaboration aims at identifying and studying TeV–PeV astrophysical neutrino sources. With the other detector (ORCA), the neutrino mass ordering will be determined by studying GeV-scale atmospheric neutrino oscillations. The first KM3NeT detection units were deployed at the Italian and French sites between 2015 and 2017. In this paper, a description of the detector is presented, together with a summary of the procedures used to calibrate the detector in-situ. Finally, the measurement of the atmospheric muon flux between 2232–3386 m seawater depth is obtained.

Abstract

Abstract Studying atmospheric neutrino oscillations in the few-GeV range with a multi-megaton detector promises to determine the neutrino mass hierarchy. This is the main science goal pursued by the future KM3NeT/ORCA water Cherenkov detector in the Mediterranean Sea. In this paper, the processes that limit the obtainable resolution in both energy and direction in charged-current neutrino events in the ORCA detector are investigated. These processes include the composition of the hadronic fragmentation products, the subsequent particle propagation and the photon-sampling fraction of the detector. GEANT simulations of neutrino interactions in seawater produced by GENIE are used to study the effects in the 1-20 GeV range. It is found that fluctuations in the hadronic cascade in conjunction with the variation of the inelasticity y are most detrimental to the resolutions. The effect of limited photon sampling in the detector is of significantly less importance. These results will therefore also be applicable to similar detectors/media, such as those in ice.

Abstract

The optical data transport system of the KM3NeT neutrino telescope at the bottom of the Mediterranean Sea will provide more than 6000 optical modules in the detector arrays with a point-to-point optical connection to the control stations onshore. The ARCA and ORCA detectors of KM3NeT are being installed at a depth of about 3500m and 2500 m, respectively and their distance to the control stations is about 100 kilometers and 40 kilometers. In particular, the two detectors are optimised for the detection of cosmic neutrinos with energies above about 1 TeV (ARCA) and for the detection of atmospheric neutrinos with energies in the range 1 GeV–1 TeV (ORCA). The expected maximum data rate is 200 Mbps per optical module. The implemented optical data transport system matches the layouts of the networks of electro-optical cables and junction boxes in the deep sea. For efficient use of the fibres in the system the technology of Dense Wavelength Division Multiplexing is applied. The performance of the optical system in terms of measured bit error rates, optical budget are presented.

Abstract

42–year–old man, former smoker, with allergic asthma. From February 2022, three weeks after the third dose of SARS–CoV–2 vaccine Spikevax (mRNA–1273), he experienced subcontinuous chest pain, worsened by breathing, sometimes with fever over 38°C, treated at home with ibuprofen and antibiotics without clinical benefit. After one month, blood chemistry tests showed increased inflammatory markers (CRP 76.5 mg/dL, ESR 55 mm/h), with negative troponin I. SARS–CoV–2 Polymerase Chain Reaction test was negative. On suspicion of subacute pericarditis, ibuprofen (600 mg b.i.d.) and colchicine (0.5 mg b.i.d.) were prescribed. After a week, he was admitted to hospital for reappearance of fever, chest pain and a syncopal episode. On ECG, negative T waves in DII, DIII, aVF; on echocardiogram, circumferential pericardial effusion (max 12 mm); indices of inflammation were increased; troponin I, auto–antibody and viral pattern were negative. On cardiac MRI: pericardial effusion (max 20 mm) with a fluid–corpuscular appearance, meso–subepicardial patchy areas of late gadolinum enhancement (LGE) at the antero– and infero–lateral wall of the left ventricle. Prednisone 25 mg/day and colchicine 1 mg/day were prescribed, with initial benefit. Two weeks later (April 2022), when the prednisone dose was reduced by half, chest pain with fever and pericardial effusion reappeared. The patient restarted prednisone at full dose (0.5 mg/Kg/day) in addition to colchicine and it was decided to do a very gradual décalage over the next six months. On follow–up cardiac MRI: thickening and enhancement of the pericardial leaflets with resolution of the fluid–filled effusion and mesomyocardial LGE striae. Further episodes of NSAID–sensitive chest pain were occasionally reported during cortisone dose reductions. In October 2022, at a dose of 2.5 mg/day dose of prednisone, there was another recurrence of pericarditis, with subcontinuous chest pain and marked increase in inflammatory indices. It was therefore decided to prescribe IL–1 inhibitor therapy (Anakinra) 100 mg/day subcutaneously for six months (ongoing follow–up). Pericarditis is a rare complication of SARS–CoV–2 mRNA vaccine, generally with a benign course, responsive to evidence–based therapy for acute pericarditis. This rare case of recurrent corticosteroid–dependent and colchicine–resistant vaccine–induced pericarditis emphasizes the importance of early diagnostic recognition and correct treatment in the acute phase.

Abstract

Funding Acknowledgements Type of funding sources: Foundation. Main funding source(s): Fondazione Intesa San Paolo Introduction Duchenne muscular dystrophy (DMD) is a genetic disorder characterized by progressive degeneration of striated muscles; in addition to skeletal muscle impairment, DMD is also characterized by progressive myocardial disfunction. The low translational value of animal models and the low availability of human samples make DMD hard to investigate; induced pluripotent stem cells (iPSCs) represent a novel tool to model this disease, preserving the genetic heritage of the patient, including the pathogenic mutation causing dystrophy. Aim Our aim is to characterize cardiomyocytes differentiated from iPSCs (iPSC-CMs) derived from healthy donors (CTRL) and DMD patients, to identify the pathophysiological mechanisms of DMD-related cardiomyopathy. Materials and Methods Cardiomyocytes are differentiated from IPSCs obtained by reprogramming isolated mononucleated blood cells from healthy donors and DMD patients. IPSC-CMs are cultured until day 60, 75 or 90 post-differentiation after plating on nanostructured substrates with two different stiffness levels: PEG-substrates, with lower rigidity, mimicking healthy extracellular tissue, and DEG-substrates, with greater rigidity, that mimic the presence of myocardial fibrosis. Through imaging techniques, we evaluated calcium handling and action potentials (AP) on DMD and CTRL iPSC-CMs by using specific fluorescent dyes for Ca2+ (CAL630) and membrane voltage (Fluovolt). Cells were stimulated at different pacing rates. Results The calcium transient amplitude of CTRL-iPSC-CMs became larger during maturation. This adaptation did not occur in DMD lines, showing a deficit calcium release due to poor maturation of the sarcoplasmic reticulum (SR). AP duration was shorter in the DMD line at d75 but at d90 we observed no differences when compared with the CTRL line. CTRL iPSC-CMs showed a marked ability to adapt to different substrate stiffnesses. Indeed, the calcium transient amplitude was larger and its kinetics faster when cells were grown on the rigid DEG substrates rather than on PEG plates. In the DMD line, however, no differences were observed between the substrates. Conclusions Our results highlight a scarce ability of DMD iPSC-CM to adapt to different substrate stiffness, resulting in mechanical and electrical impairment, especially in the presence of stiffer substrates. This might explain why cardiac impairment is usually absent in the early stages of DMD, when cardiac structural changes are still absent. However, the electrophysiological and mechanical impairment of DMD hearts may precipitate rapidly when extracellular stiffness starts to increase due to development of cardiac fibrosis.

Abstract

Background To date, the prognostic impact of transcatheter ablation (T–Abl) of supraventricular arrhythmias (SA) in HCM patients has not been satisfactorily elucidated. Objectives To assess the impact of T–Abl on clinical outcomes in a large cohort of HCM patients. Methods In this retrospective multicenter study, 570 consecutive HCM patients with SA were enrolled, 425 receiving medical therapy and 145 undergoing T–Abl. 1:1 propensity score matching (PSM) led to the inclusion of 234 patients (117 intervention group, 117 medical group) in the final analysis for endpoint evaluation. The primary outcome was a composite of all–cause mortality, heart transplantation (HT) and worsening heart failure (HF). Additionally, an inverse probability weighted (IPW) model was elaborated. Results At PSM analysis, after a median follow-up of 57.3 months, the primary endpoint occurred in 31 (26.5%) patients in the intervention group vs 38 (32.5%) in the medical group (p=0.871). Thromboembolic strokes and major arrhythmic events in the intervention vs the medical group were 9.4% vs 9.4% (p=0.367) and 5.1 vs 7.7% (p=0.741), respectively. Fewer patients in the intervention vs medical group experienced SA recurrences (64.1% vs 84.6%, p Conclusions At 5–year follow–up, T–Abl does not improve major clinical outcomes in a large cohort of HCM patients. Nevertheless, T–Abl seems to facilitate the maintenance of sinus rhythm and decelerate the progression to permanent SA. Lastly, T–Abl is usually safe in HCM.

Abstract

Treatments used in Inflammatory Bowel Disease (IBD) have been associated with enhanced risk of viral infections and viral reactivation, however, it remains unclear whether IBD patients have increased risk of Severe Acute Respiratory Syndrome Coronavirus 2 (SARS-CoV-2) infection. The aim of the study was to examine the prevalence of SARS-CoV-2 IgG positivity in IBD patients followed at our referral center. The role of treatments for IBD and risk factors for infection were also evaluated.In a prospective study, all IBD patients followed at our referral centre between May 27th and July 21st, 2020 and fulfilling the inclusion criteria were tested for SARS-CoV-2 IgG. Specific IgG antibodies were evaluated by a commercial ELISA kit and SARS-CoV-2 nasopharyngeal swab was performed in seropositive patients.Two-hundred and eighteen patients, 128 Crohn's disease (CD) and 90 Ulcerative colitis (UC) [age 44, (19-77) years; ongoing biologics in 115 (52.7%)] were enrolled. No patient had major SARS-CoV-2-related symptoms. SARS-CoV-2 IgG were detected in 3 out of 218 (1.37%) patients with IBD (2 CD and 1 UC), all on biologics (2.6%). In all of the 3 seropositive patients, the nasopharyngeal swab was negative. There was no relationship between SARS-CoV-2 seroprevalence and the demographic/clinical characteristics of IBD patients. In contrast, history of recent travel was more frequent in the SARS-CoV-2 seropositive patients (2/3; 66.6%) than in SARS-CoV-2 seronegative patients [7/215 (3.25%); p0.0001].The prevalence of SARS-CoV-2 IgG seropositivity in IBD patients appears to be comparable to the non-IBD population and not influenced by ongoing treatments. Risk factors for infection common to the general non-IBD population should be considered when managing patients with IBD.

Abstract

The authors would like to thank D Allard, A Esmaili, G Fogli, O Mena, K Murase, S Palomares Ruiz, E Parizot, S T Petcov, S Razzaque, D Semikoz, A Yu Smirnov, F L Villante, F Vissani and R Zukanovich Funchal for their support and valuable discussions and suggestions in preparing this Letter of Intent., The main objectives of the KM3NeT Collaboration are (i) the discovery and subsequent observation of high-energy neutrino sources in the Universe and (ii) the determination of the mass hierarchy of neutrinos. These objectives are strongly motivated by two recent important discoveries, namely: (1) the highenergy astrophysical neutrino signal reported by IceCube and (2) the sizable contribution of electron neutrinos to the third neutrino mass eigenstate as reported by Daya Bay, Reno and others. To meet these objectives, the KM3NeT Collaboration plans to build a new Research Infrastructure consisting of a network of deep-sea neutrino telescopes in the Mediterranean Sea. A phased and distributed implementation is pursued which maximises the access to regional funds, the availability of human resources and the synergistic opportunities for the Earth and sea sciences community. Three suitable deep-sea sites are selected, namely off-shore Toulon (France), Capo Passero (Sicily, Italy) and Pylos (Peloponnese, Greece). The infrastructure will consist of three so-called building blocks. A building block comprises 115 strings, each string comprises 18 optical modules and each optical module comprises 31 photo-multiplier tubes. Each building block thus constitutes a threedimensional array of photo sensors that can be used to detect the Cherenkov light produced by relativistic particles emerging from neutrino interactions. Two building blocks will be sparsely configured to fully explore the IceCube signal with similar instrumented volume, different methodology, improved resolution and complementary field of view, including the galactic plane. One building block will be densely configured to precisely measure atmospheric neutrino oscillations., The authors acknowledge the financial support of the funding agencies: Centre National de la Recherche Scientifique (CNRS), Commission Européenne (FEDER fund and Marie Curie Program), Institut Universitaire de France (IUF), IdEx program and UnivEarthS Labex program at Sorbonne Paris Cité (ANR-10-LABX-0023 and ANR-11-IDEX-0005-02), France; The General Secretariat of Research and Technology (GSRT), Greece; Istituto Nazionale di Fisica Nucleare (INFN), Ministero dell'Istruzione, dell’Universitàe della Ricerca (MIUR), Italy; Agence de l’Oriental and CNRST, Morocco; Stichting voor Fundamenteel Onderzoek der Materie (FOM), Nederlandseorganisatie voor Wetenschappelijk Onderzoek (NWO), The Netherlands; National Authority for Scientific Research (ANCS), Romania; Plan Estatal de Investigación (refs.

Abstract

The NEMO Phase-2 tower is the first detector which was operated underwater for more than one year at the "record" depth of 3500 m. It was designed and built within the framework of the NEMO (NEutrino Mediterranean Observatory) project. The 380 m high tower was successfully installed in March 2013 80 km offshore Capo Passero (Italy). This is the first prototype operated on the site where the italian node of the KM3NeT neutrino telescope will be built. The installation and operation of the NEMO Phase-2 tower has proven the functionality of the infrastructure and the operability at 3500 m depth. A more than one year long monitoring of the deep water characteristics of the site has been also provided. In this paper the infrastructure and the tower structure and instrumentation are described. The results of long term optical background measurements are presented. The rates show stable and low baseline values, compatible with the contribution of 40K light emission, with a small percentage of light bursts due to bioluminescence. All these features confirm the stability and good optical properties of the site., Comment: 12 pages, 17 figures

Abstract

A prototype detection unit of the KM3NeT deep-sea neutrino telescope has been installed at 3500m depth 80 km offshore the Italian coast. KM3NeT in its final configuration will contain several hundreds of detection units. Each detection unit is a mechanical structure anchored to the sea floor, held vertical by a submerged buoy and supporting optical modules for the detection of Cherenkov light emitted by charged secondary particles emerging from neutrino interactions. This prototype string implements three optical modules with 31 photomultiplier tubes each. These optical modules were developed by the KM3NeT Collaboration to enhance the detection capability of neutrino interactions. The prototype detection unit was operated since its deployment in May 2014 until its decommissioning in July 2015. Reconstruction of the particle trajectories from the data requires a nanosecond accuracy in the time calibration. A procedure for relative time calibration of the photomultiplier tubes contained in each optical module is described. This procedure is based on the measured coincidences produced in the sea by the $$^{40}$$40K background light and can easily be expanded to a detector with several thousands of optical modules. The time offsets between the different optical modules are obtained using LED nanobeacons mounted inside them. A set of data corresponding to 600 h of livetime was analysed. The results show good agreement with Monte Carlo simulations of the expected optical background and the signal from atmospheric muons. An almost background-free sample of muons was selected by filtering the time correlated signals on all the three optical modules. The zenith angle of the selected muons was reconstructed with a precision of about 3$$^circ $$∘.

Abstract

YKL-40 (also called chitinase 3-like-1 or human cartilage glycoprotein 39) is a chitinase-like protein belonging to the family 18 of glycosyl hydrolase (GH18). This protein is involved in the inflammatory process acting as pro-inflammatory cytokine secreted by neutrophils, activated human macrophages, vascular smooth muscle cells and cancer cells. It has been shown that YKL-40 has a role in pathological tissue remodeling and development of fibrosis of several diseases. To date, the biological and pathophysiological function of YKL-40 protein in pulmonary diseases is still unclear. This review focuses on the role of YKL-40 in diagnosis and monitoring of different lung diseases in order to assess whether this protein could be used as biomarker of specific conditions featured by inflammation and fibrosis. A comprehensive review of the literature using PubMed database, with appropriate terms, was undertaken for articles in English published since 1997. The literature search was undertaken in October 2014.

Abstract

Human chitotriosidase (Chit) increases during the osteoclast differentiation and their activity. We demonstrated that serum Chit was significantly higher in osteoporotic subjects than in healthy control ones and revealed a negative correlation between Chit and bone mineral density (BMD). This is the first study showing a correlation between Chit and severe postmenopausal osteoporosis. Mammalian chitinases exert important biological roles in the monocyte lineage and chronic inflammatory diseases. In particular, Chit seems to promote bone resorption in vitro. No in vivo studies have been performed to confirm this finding. We aim to evaluate Chit activity in postmenopausal women affected by severe osteoporosis. In this cross-sectional study, 91 postmenopausal women affected by osteoporosis and 61 with either osteopenia or normal BMD were screened. All subjects were assessed by dual-energy X-ray absorptiometry (DXA) and X-ray vertebral morphometry. Osteoporotic subjects were considered eligible if they were affected by at least one vertebral osteoporotic fracture (group A = 57 subjects). Osteopenic or healthy subjects were free from osteoporotic fractures (group B = 51 subjects). Enzymatic Chit and serum β-CrossLaps (CTX) were measured in the whole population. Group A showed higher serum levels of beta-CTX compared to group B (0.40 ± 0.26 ng/mL vs 0.29 ± 0.2 ng/mL, p = 0.022). Chit was significantly higher in group A than in group B (1042 ± 613 nmol/mL/h vs 472 ± 313 nmol/mL/h, p

Abstract

The timing calibration is a delicate operation to perform for assuring the full functionality of a large underwater neutrino telescope. In this paper we illustrate the main features of our system for timing calibration tailored to the needs of the prototype of the NEMO (NEutrino Mediterranean Observatory) apparatus. We point out that the approach proposed can be easily adapted to work in any underwater neutrino telescope.

Abstract

In 2005, the ANTARES Collaboration deployed and operated at a depth of 2500 m a so-called Mini Instrumentation Line equipped with Optical Modules (MILOM) at the ANTARES site. The various data acquired during the continuous operation from April to December 2005 of the MILOM confirm the satisfactory performance of the Optical Modules, their front-end electronics and readout system, as well as the calibration devices of the detector. The in-situ measurement of the Optical Module time response yields a resolution better than 0.5 ns. The performance of the acoustic positioning system, which enables the spatial reconstruction of the ANTARES detector with a precision of about 10 cm, is verified. These results demonstrate that with the full ANTARES neutrino telescope the design angular resolution of better than $0.3^\circ$ can be realistically achieved., Comment: 18 pages, 12 figures, submitted to Astroparticle Physics

Abstract

Activities leading to the realization of a km3 Cherenkov neutrino detector, carried out by the NEMO collaboration, are described. Long term exploration of a 3500 m deep site in the Mediterranean close to the Sicilian coast has shown that it is optimal for the installation of the detector. A complete feasibility study, which has considered all the components of the detector, as well as its deployment, has been carried out demonstrating that technological solutions exist for the realization of the km3 detector. The realization of a technological demonstrator (the NEMO Phase 1 project) is under way.

Abstract

The 1,2-fucosyl-oligosaccharides, and among these the 2’-fucosyl-lactose (2’-FL) and lacto-N-fucopentaose (LNFP)-I, are quantitatively the most represented oligosaccharides of human milk. They are also seen to represent an important immune device to prevent nursing infants from severe infectious diarrhoea. Recent evidences show that the appearance of 2’-FL and LNFP-I in human colostrums is synchronised with the macrophage inhibition and that LNFP-III induces a Th2 response from the mouse peripheral immune system. Since mannosyl-fucosyl receptors are described on the macrophage surface, all these evidences allow us to investigate on the possible immune function of human 2’-FL and LNFP-I in vitro on LPS-activated mononuclear cells (MNC) from 12 patients with multiple sclerosis (MS) and 20 matched health controls (HC). We found that 2’-FL and LNFP-I significantly decrease, to a different extent, the MNC proliferation from both HC and MS patients, in a linear and dose-dependent manner. 2’-FL and LNFP-I also reduce the production of IL-12 and IFN-γ, particularly in MS patients as compared to HC (p=0.01 and p

Abstract

Pathological cardiac hypertrophy is associated with the expression of a gene profile reminiscent of foetal development. The non selective beta-adrenoceptor antagonist propranolol is able to blunt cardiomyocyte hypertrophic response in pressure-overloaded hearts. It remains to be determined whether propranolol also attenuates the expression of hypertrophy-associated foetal genes.To address this question, the foetal gene programme, of which atrial natriuretic peptide (ANP), the beta-isoform of myosin heavy chain (beta-MHC), and the alpha-skeletal muscle isoform of actin (skACT) are classical members, was induced by thoracic aortic coarctation (TAC) in C57BL/6 mice, or by phenylephrine, a selective alpha(1)-adrenoceptor agonist, in cultured rat neonatal cardiomyocytes.In TAC mice, the left ventricular weight-to-body weight (LVW/BW) ratio increased by 35% after 2 weeks. Levels of ANP, beta-MHC and skACT mRNA in the left ventricles increased 2.2-fold, 2.0-fold and 12.1-fold, respectively, whereas alpha-MHC and SERCA mRNA levels decreased by approximately 50%. Although propranolol blunted cardiomyocyte growth, with approximately an 11% increase in the LVW/BW ratio, it enhanced the expression of ANP, beta-MHC and skACT genes (10.5-fold, 27.7-fold and 22.7-fold, respectively). Propranolol also enhanced phenylephrine-stimulated ANP and beta-MHC gene expression in cultured cardiomyocytes. Similar results were obtained with metoprolol, a selective beta(1)-adrenoceptor antagonist, but not with ICI 118551, a beta(2)-adrenoceptor antagonist.Propranolol enhances expression of the hypertrophy-associated foetal genes mainly via the beta(1)-adrenoceptor blockade. Our results also suggest that, in pressure-overloaded hearts, cardiomyocyte growth and foetal gene expression occur as independent processes.

Abstract

The timing calibration is a delicate operation to perform for assuring the full functionality of a large underwater neutrino telescope. In this paper we illustrate the main features of our system for timing calibration tailored to the needs of the prototype of the NEMO (NEutrino Mediterranean Observatory) apparatus. We point out that the approach proposed can be easily adapted to work in any underwater neutrino telescope.

Abstract

The ANTARES neutrino telescope, currently under construction at 2500 in depth off the French Mediterranean coast, will contain 12 detection lines, powered and read out through a deep-sea junction box (JB) hub. Electrical energy from the shore station is distributed through a transformer with multiple secondary windings and a plugboard with 16 deep sea-mateable electro-optic connectors. Connections are made to the JB outputs using manned or remotely operated submersible vehicles. The triply redundant power management and slow control system is based on two identical AC-powered systems, communicating with the shore through 160 Mb/s fibre G-links and a third battery-powered system using a slower link. We describe the power and slow control systems of the underwater hub. (c) 2006 Elsevier B.V. All rights reserved.

Abstract

According with the R&D philosophy of the first phase of NEMO experiment, an extensive investigation have been carried out in order to find practical alternatives to the standard design of pressure vessels for junction boxes that should operate on the sea bed for a long lifetime.Both technical and economical points of view have been considered, as well as reliability. Possible suppliers have been contacted to check the feasibility of the different solutions and estimate their cost. A final trade-off has been proposed, to help the collaboration to choose the solution for the detector prototype phase.

39. Informazione e processi di apprendimento nello sviluppo locale

Author

M. Musumeci

Abstract

Nel 1961, Stigler in un suo articolo definiva l informazione a valuable resource , una risorsa preziosa, …and yet occupies a slum dwelling in the town of economics , e tuttavia risiede nei bassifondi della città della teoria economica Da allora, i contributi analitici sul ruolo economico dell informazione, sia con riferimento a temi di microeconomia che di macroeconomia, sono cresciuti notevolmente, ed oggi l Economia dell informazione occupa un posto di rilievo all interno della teoria economica. Le asimmetrie informative, i contratti, le aspettative, i mercati efficienti, sono soltanto alcuni degli argomenti principali affrontati dalla teoria dell informazione e dalla cui trattazione sono scaturite visioni diverse sul funzionamento del sistema economico. Fino ai primi anni 60, com è noto, la teoria economica assumeva che il mercato di concorrenza perfetta operasse in condizioni di assoluta trasparenza e a costi nulli; inoltre, si pensava che gli operatori economici, nell ipotesi di conoscenza non perfetta delle variabili rilevanti per le loro decisioni, si adattassero passivamente alle condizioni di incertezza. Successivamente, gran parte della letteratura ha posto al centro della propria riflessione i problemi generati da informazione incompleta e asimmetrica - quali, ad esempio, l allocazione delle risorse nel mercato dei beni, come nel mercato del lavoro e del credito - assumendo che gli individui, presa coscienza della incompletezza delle informazioni (sia essa riferita ai prezzi che ai beni scambiati), reagiscano all incertezza mettendo in atto comportamenti finalizzati ad una maggiore acquisizione ed elaborazione dell informazione . Nasce, cosí, l Economia dell informazione, nella quale la categoria economica informazione viene rivalutata e posta al centro di attente analisi da parte della teoria economica stessa. Oggi, più che mai, le economie industrializzate sono guidate dal sapere, knowledge based economics , come sottolinea l OCSE nel suo rapporto del 1998, con implicazioni notevoli per le politiche industriali. La conoscenza costituisce, infatti, il maggior input del processo produttivo ed una delle variabili fondamentali nel sentiero di espansione di una impresa. Ora, poiché l innovazione tecnologica, intesa come il risultato dell attività di Ricerca e Sviluppo, è assimilabile all informazione, l acquisizione e lo scambio sia di conoscenze importate , a prevalente contenuto scientifico, che di conoscenze localizzate , basate su saperi taciti ed esperienze localizzate, costituiscono l elemento fondamentale per la realizzazione di un processo di sviluppo. La carenza di adeguate informazioni, infatti, ostacola il processo innovativo e dunque la crescita delle imprese. Peraltro, la rivoluzione informatica, con la computerizzazione dei processi - siano essi agricoli, industriali o terziari - ha segnato il passaggio da un economia, per cosí dire, manifatturiera ad un economia della conoscenza, in cui diviene predominante, in una prospettiva di innovazione aziendale, il possesso e la diffusione di informazioni. Con questo saggio, intendiamo affrontare tale tematica tenendo presente il ruolo delle nuove tecnologie dell informazione in relazione non soltanto ai processi produttivi, e dunque all offerta, ma anche con riferimento alla struttura della domanda. La nostra attenzione sarà rivolta in particolare alle imprese che operano nel settore delle Conserve alimentari, da noi individuato come caso-studio. attribuis L obiettivo è quello di verificare se il quadro teorico di riferimento - che stabilisce, come si è detto, un legame tra sviluppo del tessuto imprenditoriale locale e capacità di acquisizione e diffusione di nuove conoscenze - risulti in qualche modo confermato dalle prime evidenze empiriche riferite ad un campione di piccole imprese, appartenenti al suddetto settore. In particolare, attraverso l analisi dei questionari, si cercherà di ricostruire il sentiero di crescita delle nostre imprese, il ruolo esercitato dalle conoscenze, la loro propensione ad innovare e gli eventuali ostacoli che hanno frenato questo processo.

Abstract

Abstract??In theAnophelesmidgut,Plasmodium falciparumproduces a specific chitinase able to penetrate the blood meal surrounding the chitin-containing peritrophic membrane (PM). High levels of an analogous chitinase, chitotriosidase (CHIT), may be found in human blood, being the markers of macrophage activation. To verify the hypothesis that CHIT present in malaria patient blood could help parasite to overcome PM, we carried out a bioassay by feedingAnopheles stephensifemales on an artificial apparatus that contained human blood from four different sources and with different chitinase concentrations: (1) healthy donors, as negative controls; (2) patients with malaria; (3) patients with Gaucher disease; and (4) whole blood enriched with commercialP. falciparumchitinase, as positive controls. After 16, 20 and 24?h of bloodfeeding, mosquitoes were dissected to extract the midgut and assess the effect of the different chitinases on membrane structure. Optical microscopy showed that formation of PM was clearly complete after 16?h in the posterior midgut fromAnophelesalready fed with healthy donor bloods. By contrast, PM formation was visible after 16?h in the posterior midgut of mosquitoes fed with malaria and Gaucher patient bloods but appeared clearly damaged at 20 and 24?h. At the same time, the PM formation was almost completely inhibited in the midgut ofAnophelesfed withP. falciparumchitinase-enriched bloods. These alterations were clearly confirmed by transmission electronic microscopy. In the present paper, we demonstrate that human CHIT from different sources is active on anophelines? PM.

Abstract

Marijuana use can be determined by detecting delta 9-tetrahydrocannabinol-11-oic acid (THC-11-oic acid) in urine. For this, we describe a procedure for its chemical detection by using sequential thin-layer chromatography on a single plate for rapid isolation and identification. A volume of urine containing 50 mg of creatinine is concentrated by evaporation to 10 ml, the concentrate is enzymically hydrolyzed for 30 minutes and extracted with ether, and the extract is purified by treatment with NaHCO3, then chromatographed in an alkaline and an acidic solvent sequence. The plate is sprayed with Fast Blue Salt B, and THC-11-oic is identified by its characteristic mobility and its characteristic colour reaction. The sensitivity is 0.5 microgram. THC-11-oic acid has been detected in urines collected after the smoking of one standard cigarette containing 16-18 mg of delta 9-tetrahydrocannabinol and in 34 of the first 100 tests of spontaneously collected urines of patients in a hospital drug-abuse treatment program. Multiple samples are easily carried through this extraction procedure. Evaporative concentration takes about 20 min per sample, and the analysis of eight concentrated samples take about 5.5 h.

Abstract

ABSTRACT Objective: To identify factors associated with prolonged weaning and mortality in critically ill COVID-19 patients admitted to ICUs and under invasive mechanical ventilation. Methods: Between March of 2020 and July of 2021, we retrospectively recorded clinical and ventilatory characteristics of critically ill COVID-19 patients from the day of intubation to the outcome. We classified the patients regarding the weaning period in accordance with established criteria. A logistic regression analysis was performed to identify variables associated with prolonged weaning and mortality. Results: The study involved 303 patients, 100 of whom (33.0%) had a prolonged weaning period. Most of the patients were male (69.6%), 136 (44.8%) had more than 50% of pulmonary involvement on chest CT, and 93 (30.6%) had severe ARDS. Within the prolonged weaning group, 62% died within 60 days. Multivariate analysis revealed that lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were significantly associated with prolonged weaning, whereas age and prolonged weaning were significantly associated with mortality. Conclusions: Prolonged weaning can be used as a milestone in predicting mortality in critically ill COVID-19 patients. Lung involvement greater than 50% on CT and delay from intubation to the first separation attempt from mechanical ventilation were identified as significant predictors of prolonged weaning. These results might provide valuable information for healthcare professionals when making clinical decisions regarding the management of critically ill COVID-19 patients who are on mechanical ventilation.

This digital optical module has a novel design with a very large photocathode area segmented by the use of 31 three inch photomultiplier tubes. It has been integrated in the ANTARES detector for in-situ testing and validation. This paper reports on the first months of data taking and rate measurements. The analysis results highlight the capabilities of the new module design in terms of background suppression and signal recognition. The directionality of the optical module enables the recognition of multiple Cherenkov photons from the same40 K decay and the localisation of bioluminescent activity in the neighbourhood. The single unit can cleanly identify atmospheric muons and provide sensitivity to the muon arrival directions

Abstract

In March 2013, the NEMO Phase 2 tower has been successfully installed in the Capo Passero site, at a depth of 3500 m and 80 km off from the southern coast of Sicily. The unfurled tower is 450 m high; it is composed of 8 mechanical floors, for a total amount of 32 PMTs and various instruments for environmental measurements. The tower positioning is achieved by an acoustic system. The tower is continuously acquiring and transmitting all the measured signals to shore. Data reduction is completely performed in the Portopalo shore station by a dedicated computing facility connected to the persistent storage system at LNS, in Catania. Results from the last 9 months of acquisition will be presented. In particular, the analyzed optical rates, showing stable and low baseline values, are compatible with the contribution mainly of 40K light emission, with a small percentage of light bursts due to bioluminescence. These features reveal the optimal nature of the Capo Passero abyssal site to host a km3-sized Neutrino Telescope. © 2014 IOP Publishing Ltd and Sissa Medialab srl.

Abstract

The KM3NeT Collaboration is currently constructing a multi-site high-energy neutrino telescope in the Mediterranean Sea consisting of matrices of pressure-resistant glass spheres, each holding a set of 31 small-area photomultipliers. The main goals of the telescope are the observation of neutrino sources in the Universe and the measurement of the neutrino oscillation parameters with atmospheric neutrinos. A relative time synchronisation between photomultipliers of the nanosecond order needed to guarantee the required angular resolution of the detector. Due to the large detector volumes to be instrumented by KM3NeT, a cost reduction of the different systems is a priority. To this end, the inexpensive Nanobeacon has been designed and developed by the KM3NeT Collaboration to be used for detector time-calibration studies. At present, more than 600 Nanobeacons have been already produced. The characterisation of the optical pulse and the wavelength emission profile of the devices is critical for the time calibration. The optical pulse rise time has been quantified as less than 3 ns, while the Full Width Half Maximum is less than 6 ns. The wavelength drift, due to a variation of the supply voltage, has also been qualified as lower than 10 nm for the full range of the Nanobeacon. In this paper, more details about the main features of the Nanobeacon design, production and operation, together with the main properties of the light pulse generated are described., French National Research Agency (ANR), European Commission ANR-15-CE31-0020, Centre National de la Recherche Scientifique (CNRS) Commission Europeenne (FEDER fund) Commission Europeenne (Marie Curie Program) Institut Universitaire de France (IUF) LabEx UnivEarthS, Paris Ile-de-France Region, France ANR-10-LABX-0023 ANR-18-IDEX-0001, Shota Rustaveli National Science Foundation of Georgia (SRNSFG), Georgia FR-18-1268, German Research Foundation (DFG), Greek Ministry of Development-GSRT, Istituto Nazionale di Fisica Nucleare (INFN), Ministero dell'Universita e della Ricerca (MIUR), PRIN 2017 program, Italy NAT-NET 2017W4HA7S, Ministry of Higher Education Scientific Research and Professional Training, ICTP, Morocco AF-13, Netherlands Organization for Scientific Research (NWO) Netherlands Government, National Science Centre, Poland 2015/18/E/ST2/00758, National Authority for Scientific Research (ANCS), Romania, Ministerio de Ciencia, Innovacion, Investigacion..

Abstract

[EN] Detection of high-energy neutrinos from distant astrophysical sources will open a new window on the Universe. The detection principle exploits the measurement of Cherenkov light emitted by charged particles resulting from neutrino interactions in the matter containing the telescope. A novel multi-PMT digital optical module (DOM) was developed to contain 31 3-inch photomultiplier tubes (PMTs). In order to maximize the detector sensitivity, each PMT will be surrounded by an expansion cone which collects photons that would otherwise miss the photocathode. Results for various angles of incidence with respect to the PMT surface indicate an increase in collection efficiency by 30% on average for angles up to 45 degrees with respect to the perpendicular. Ray-tracing calculations could reproduce the measurements, allowing to estimate an increase in the overall photocathode sensitivity, integrated over all angles of incidence, by 27% (for a single PMT). Prototype DOMs, being built by the KM3NeT consortium, will be equipped with these expansion cones., This work is supported through the EU, FP6 Contract no. 011937, FP7 grant agreement no. 212252, and the Dutch Ministry of Education, Culture and Science.

Abstract

A 13-inch Optical Module (OM) containing a large-area (10-inch) photomultiplier was designed as part of Phase-2 of the NEMO project. An intense R&D activity on the photomultipliers, the voltage supply boards, the optical coupling as well as the study of the influences of the Earth's magnetic field has driven the choice of each single component of the OM. Following a well-established production procedure, 32 OMs were assembled and their functionality tested. The design, the testing and the production phases are thoroughly described in this paper. © 2013 IOP Publishing Ltd and Sissa Medialab srl.

Abstract

The NEMO collaboration proposes to build an underwater neutrino telescope located South-East off the Sicily coast. This paper describes the concepts underlying the communication link design going over the whole data acquisition and transport from the front-end electronics to the module sending data on-shore through a fiber optic link which relies on Dense Wavelength Division Multiplexing. An on-shore board, plugged into a PC, extracts and distributes data both to first-level trigger and control systems. Underwater apparatus monitoring and controls are guaranteed by oceanographic instruments and dedicated sensors, whose data are packed and sent back to shore using the same optical link. The communication is fully bidirectional, allowing transmission of timing and control commands. The architecture described here provides a complete real-time data transport layer between the onshore laboratory and the underwater detector. During winter 2006 a first prototype of the apparatus has been deployed: calibration results from the currently working system are here reported.
