    Digitalisation For Sustainable Infrastructure: The Road Ahead

    Get PDF
    In today’s tumultuous and fast-changing times, digitalisation and technology are game changers in a wide range of sectors and have a tremendous impact on infrastructure. Roads, railways, electricity grids, aviation, and maritime transport are deeply affected by the digital and technological transition, with gains in terms of competitiveness, cost-reduction, and safety. Digitalisation is also a key tool for fostering global commitment towards sustainability, but the race for digital infrastructure is also a geopolitical one. As the world’s largest economies are starting to adopt competitive strategies, a level playing field appears far from being agreed upon. Why are digitalisation and technology the core domains of global geopolitical competition? How are they changing the way infrastructure is built, operated, and maintained? To what extent will road, rail, air, and maritime transport change by virtue of digitalisation, artificial intelligence, and the Internet of Things? How to enhance cyber protection for critical infrastructure? What are the EU’s, US’ and China’s digital strategies?Publishe

    The Global Quest for Sustainability

    Get PDF
    In the aftermath of the pandemic, global demand for infrastructure is booming. National plans around the world show that infrastructure is likely to provide the backbone for a resurgence in public expenditure, and to support growth in economies badly hit by the pandemic. As all the biggest powers and blocs (the EU, the US, China, and Japan) have recently announced their plans for climate or carbon neutrality, the room and need for green and sustainable infrastucture are greatly expanding. Decarbonisation and digitalisation will be underpinning this latest investment drive in infrastructure, with sustainability and ESG principles at its core. However, infrastructure expenditure will not come without risk: after the pandemic, the world will be left with the highest levels of public and private debt since World War II, and the sustainability of key investment decisions must be carefully evaluated. How to foster quality and sustainable infrastructure investment? What role for the private sector? What future for sustainable mobility? What kind of policies will countries adopt to reach carbon neutrality?Publishe

    Italian allora, French alors : functions, convergences and divergences

    The functions, convergences, and divergences of Italian allora and French alors are analyzed in two Italian texts (the Novellino, in Old Italian, and Paso Doble, in Modern Italian) and their French translations. The discourse marker is used differently in the two languages, and the contrastive analysis allows us to better assess those differences, by explicitly quantifying the degree of correspondence, omissions, and non-literal translations. Furthermore, our work confirms the existence of functions which may be identified as more central or more peripheral within a certain configuration, and emphasizes the existence of cross-language preferences for a more/less rich set of forms for expressing a particular function. The polyfunctionality and context-boundness which characterize discourse markers in general are held responsible for differences in translation, thus motivating the several shades of meaning which distinguish Italian allora (with regard both to Old and Modern Italian) from French alors.En aquest article analitzem les funcions, les convergències i les divergències del connector italià allora i del francès alors a partir de dos textos italians (Novellino, en italià antic, i Paso Doble, en italià actual) i les corresponents traduccions franceses. Aquest marcador del discurs s'utilitza de manera diferent en les dues llengües com l'anàlisi contrastiva permet posar de manifest quantificant explícitament el grau de correspondència, omissions i traduccions no literals. Més encara, aquest treball confirma l'existència de funcions que poden ser identificades com a més centrals o més perifèriques dins d'una certa configuració i també manifesta l'existència de preferències interlingüístiques en un grup de formes més o menys ric per a expressar una funció particular. La polifuncionalitat i la dependència contextual que caracteritza els marcadors del discurs en general expliquen les diferències de traducció i, per tant, motiven els diferents matisos de significat que diferencien allora (tant respecte a l'italià antic com a l'actual) del marcador francès alors

    DESIGN OF A PROTOTYPE UNMANNED LIGHTER-THAN-AIR PLATFORM FOR REMOTE SENSING: STRUCTURAL DESIGN AND OPTIMIZATION

    This work presents the structural design of a new Remotely Piloted Aircraft System (RPAS) concept for land survey applications. The RPAS Lighter-Than-Air (LTA) platform is equipped with a thrust vectoring control system made of six propellers attached to a single-rib exoskeletal load-bearing structure. The load-bearing structure is optimized to minimize structural mass, maximize payload capability, and meet the airship's operational requirements. A finite element model of the load-bearing structure was developed and analyzed under normal operating conditions of the airship, such as mid-air hovering and parking. Additionally, various failure cases, such as crash landing and control system failure, leading to haphazard operation of the propellers, were considered to simulate extreme load conditions on the airship exoskeletal structure. Airship slenderness was also considered an important design parameter and was optimized to maximize aerodynamic performance. A twin paper describes the other non-structural aspects of the airship design

    Background Schizophrenic patients show deficits in social cognition, functioning and in interpreting facial expressions. These disabilities contribute to global impairment in social and relational skills. Data started being collected in the context of the Italian Network of Research on Psychosis headed by Prof. Maj and Prof. Galderisi (Galderisi S et al. The influence of illness-related variables, personal resources and context-related factors on real-life functioning of people with schizophrenia. World Psychiatry 2014:275\u201387. Mucci A et al. The Specific Level of Functioning Scale: Construct validity, internal consistency and factor structure in a large Italian sample of people with schizophrenia living in the community. Schizophr Res 2014;159(1):144-50); collection in our centre went on also after the conclusion of the national project. Aims To identify the correlations among social inference, facial emotion identification and clinical history and therapies in schizophrenic patients. Material and methods We recruited patients with Schizophrenia referring to our Psychiatry Ward, AOU Maggiore della Carit\ue0, Novara, Italy. Socio-demographic characteristics were gathered; assessment of patients included The Awareness of Social Inference Test (TASIT), the Facial Emotion Identification Test (FEIT), the Positive and Negative Syndrome Scale (PANSS) and the Brief Negative Symptom Scale (BNSS). Results Data collection is still ongoing. In a previous study we pointed out that schizophrenic patients showed social skills deficits and difficulties in identifying facial emotions. These features underlie poor and limited social relationships proper to schizophrenia. Our preliminary results revealed thatidentification of facial emotions is influenced by psychopathological symptoms especially by avolition, blunted affect and alogia. Implication will be discussed

    BACKGROUND Prognosis of Takotsubo syndrome (TTS) remains controversial due to scarcity of available data. Additionally, the effect of the triggering factors remains elusive. OBJECTIVES This study compared prognosis between TTS and acute coronary syndrome (ACS) patients and investigated short- and long-term outcomes in TTS based on different triggers. METHODS Patients with TTS were enrolled from the International Takotsubo Registry. Long-term mortality of patients with TTS was compared to an age- and sex-matched cohort of patients with ACS. In addition, short- and long-term outcomes were compared between different groups according to triggering conditions. RESULTS Overall, TTS patients had a comparable long-term mortality risk with ACS patients. Of 1,613 TTS patients, an emotional trigger was detected in 485 patients (30%). Of 630 patients (39%) related to physical triggers, 98 patients (6%) had acute neurologic disorders, while in the other 532 patients (33%), physical activities, medical conditions, or procedures were the triggering conditions. The remaining 498 patients (31%) had no identifiable trigger. TTS patients related to physical stress showed higher mortality rates than ACS patients during long-term follow-up, whereas patients related to emotional stress had better outcomes compared with ACS patients. CONCLUSIONS Overall, TTS patients had long-term outcomes comparable to age- and sex-matched ACS patients. Also, we demonstrated that TTS can either be benign or a life-threating condition depending on the inciting stress factor. We propose a new classification based on triggers, which can serve as a clinical tool to predict short- and long-term outcomes of TTS.

    OBJECTIVE Consistent with the cognitive reserve hypothesis, higher education and occupation attainments may help persons with neurodegenerative dementias to better withstand neuropathology before developing cognitive impairment. We tested here the cognitive reserve hypothesis in patients with frontotemporal dementia (FTD), with or without pathogenetic granulin mutations (GRN+ and GRN-), and in presymptomatic GRN mutation carriers (aGRN+). METHODS Education and occupation attainments were assessed and combined to define Reserve Index (RI) in 32 FTD patients, i.e. 12 GRN+ and 20 GRN-, and in 17 aGRN+. Changes in functional connectivity were estimated by resting state fMRI, focusing on the salience network (SN), executive network (EN) and bilateral frontoparietal networks (FPNs). Cognitive status was measured by FTD-modified Clinical Dementia Rating Scale. RESULTS In FTD patients higher level of premorbid cognitive reserve was associated with reduced connectivity within the SN and the EN. EN was more involved in FTD patients without GRN mutations, while SN was more affected in GRN pathology. In aGRN+, cognitive reserve was associated with reduced SN. CONCLUSIONS This study suggests that cognitive reserve modulates functional connectivity in patients with FTD, even in monogenic disease. In GRN inherited FTD, cognitive reserve mechanisms operate even in presymptomatic to clinical stages

    Background: The PRECISE-DAPT and PARIS risk scores (RSs) were recently developed to help clinicians at individualizing the optimal dual antiplatelet therapy duration (DAPT) after percutaneous coronary intervention (PCI). Nevertheless, external validation of these RSs it has not yet been performed in ACS (acute coronary syndrome) patients treated with prasugrel or ticagrelor in a real- world scenario. Methods: 4424 ACS patients who underwent PCI and survived to hospital discharge, from January 2012 to December 2016 at 12 European centers, were included. PRECISE-DAPT and PARIS bleeding RS, as well as PARIS ischemic RS, were computed, and their performance at predicting major bleeding (MB; BARC type 3 or 5) and ischemic events (MI and stent thrombosis) during follow up was compared. Results: After a median follow-up of 14 (interquartile range 12–20.9) months, 83 (1.88%) patients developed MB and 133 (3.0%) suffered an ischemic episode. PRECISE-DAPT performed better than PARIS bleeding RS (c-statistic = 0.653 vs. 0.593; p =.01 for comparison) in predicting MB. The RSs performance for MB prediction remained consistent in STEMI patients (c-statistic = 0.632 vs 0.575) or in those treated with prasugrel (c-statistic = 0.623 vs 0.586). PARIS ischemic RS exhibited superior discrimination in predicting ischemic complications compared to PRECISE-DAPT (c-statistic = 0.604 vs 0.568 p =.05 for comparison). Conclusion: Our data provide support to the use of PRECISE-DAPT in MB risk stratification for patients receiving DAPT in form of aspirin and prasugrel or ticagrelor whereas the PARIS ischemic RS has potential to complement the risk prediction with respect to ischemic events
