Sit-to-Walk predicts Freezing of Gait status over than cognitive load: an experimental study with Linear Discriminant Analysis
Freezing of Gait (FoG) is one of the most debilitating symptom of patients with Parkinson Disease (PwP) as it could leads to fall and loss of independence. We evaluated the motor behavior in simple and complex gait movements with three groups of participants: PwP with and without FoG in ON state condition, and participants without neurologic and gait disorders. All participants were required to walk, to begin to walk (Step Initiation), and raise from a chair for walking (Sit-to-Walk). Analysis of variance helped to identify task-specific kinematic and kinetic variables which differentiate among the three groups. Classification accuracy of such variables was obtained by training a Linear Discriminant Analysis – LDA algorithm on reduced sub-samples, and by testing it on the left out subjects
Above and below equator
The conception of Global North is referring, from geographical point of view to the Northern Hemisphere located above the Equator and the Global South, but the expres-sion is more used to describe a grouping of countries along socio-economic and political charac-teristics. The namely the part of the earth below the Equator is transforming more and more. Major dynamics of historical, post and new colonisation, greater economic discrepancy, politics power and subsequent accessibility to resources have created and engendered throughout the years the geographical difference. These phenomena inevitably lead to different approaches in spatial planning, territorial governance and particularly, in emergency assessment. This paper illustrates two different approaches to deal with natural hazards that occurred, one in the Global South, specifically the 2019 Tropical Cyclone Idai in the central area of Mozambique, along with the 2016 massive earthquake that took place mainly in the city of Amatrice in the central region of Lazio (Italy). This study seeks to investigate both hazardous events in their overall occurrence, focusing on the undertaken emergency approaches and the variety of diffi-culties encountered along these two challenging processes of recovery: geographical and geo-morphological intrinsic features - the presence of the Indian Ocean and the configuration of the Mozambican country, so as the disposition of the Italian country over the Eurasian and African plate, resulting in a consistent number of faults throughout Italy -, multi-level approach of administrative sectors, legal framework and community awareness. This parallel discussion will eventually highlight the need to improve communities and professionals’ preparedness, learn from previous mistakes, capacity building and raise awareness towards more conscious, fairer strategies to tackle emergencies. To this end, the main advantages identified in the BIM technol-ogy that could make major changes in this field, are certainly interoperability and the possibility of simulating the work process in a virtual way, using a constantly updated template. These and other innovative aspects will be discussed and analysed

Results from the BCs tested for detecting blaCTX-M, blaKPC, blaNDM, blaOXA-48-like, and blaVIM genes by the eazyplex®, SuperBug CRE assay in Ec and Kp organisms had been notified for antimicrobial therapy consulting.Results: In 321 BSI episodes studied, we found that 151 (47.0%) of Ec or Kp organisms harbored blaCTX-M and/or blaKPC and/or blaVIM (meantime from BC collection: 18.5 h). Empirical antimicrobial treatment was appropriate in 21.8% (33/151) of BSIs, namely 5.9% (3/51) of BSIs caused by KPC/VIM producers and 30.0% (30/100) of BSIs caused by CTX-M producers. After notification of results, the IDCT modified antimicrobial therapy (mean time from BC collection: 20 h) such that the proportion of appropriate treatments increased to 84.8% (128/151) of BSIs, namely 70.6% (36/51) of BSIs caused by KPC/VIM producers and 92.0% (92/100) of BSIs caused by CTX-M producers.Conclusion: Our study shows that a rapid diagnostic-driven clinical strategy allowed for early prescription of potentially effective antimicrobial therapy in BSIs caused by CTX-M ESBL- and/or KPC/VIM carbapenemase-producing Ec and Kp organisms.Keywords: Escherichia coli, Klebsiella pneumoniae, bloodstream infection, drug resistance, targeted therapy, infectious disease consultatio

Abstract
SiC/SiC ceramic matrix composites (SiCf/SiC CMCs) are regarded as the new materials for the hot-section components of aircraft gas turbine engines, since they have one-third of the density of metallic superalloys, a higher temperature capability, good mechanical strength, and excellent thermal shock resistance. However, high-temperature water-vapor-rich combustion gases can induce severe surface recession phenomena in SiC/SiC leading to component failure. For this reason, it is necessary to design protective coatings, i.e., environmental barrier coatings (EBCs), able to protect the SiC/SiC surface in combustion environments. In the present work, ytterbium monosilicate (Yb2SiO5), stable when exposed to water vapor at high temperatures, and ytterbium disilicate (Yb2Si2O7), characterized by a thermal expansion coefficient closer to that of the substrate, were selected for a multilayer EBC system. EBCs were processed using the atmospheric plasma spray (APS) technique. A set of deposition parameters were tested, varying the power of the torch, and the composition and microstructure of the deposited coatings were studied in terms of porosity, crack density, and post-deposition phase retention by performing SEM, EDS, and XRD analysis. The results allow for the definition of the influence of deposition parameters on the final properties of multilayer EBC coatings
Unveiling the temporal dynamics of emotional attentional capture with eye movements: from an automatic to a perceptual component
Humans are natural emotion detectors and particularly predisposed to attend to emotions conveyed by facial expressions. The compulsory attraction to emotions, however, gets challenging when multiple emotional stimuli compete for attention, as in the emotion comparison task. In this task, participants are asked to choose which of two simultaneously presented faces displays a specific emotion (happiness/anger). When the two faces both express a different emotion intensity, the selection is driven by a purely perceptual attentional component: participants respond faster to the face displaying the strongest emotion (i.e., the emotional semantic-congruency effect, ESC), and this effect is stronger for face pairs that contain globally positive rather than negative emotional faces (i.e., the size-effect). In this experiment, we exploited the temporal dynamics of the emotion comparison task by tracking participants' eye movements using gaze-contingent displays. We expected that a perceptually driven attentional component like the ESC will rise over time following a purely automatic attentional component based on a left-to-right visual asymmetry. Analysis of fixation accuracy and dwell time fully corroborated this expectation. On the first fixation, participants were more accurate and dwell longer on the left face when it was the target, according to an automatic attentional component. The pattern of accuracy and dwell time on the second fixation was instead consistent with the ESC. Overall, our pattern of results indicates that attentional capture in emotion comparison task arises from the linear combination of purely automatic and perceptual (i.e., the ESC) attentional components over time [This research was supported by a founding for the research (RESRIC-FANTONI2018, Department of Life Sciences, University of Trieste) to CF and an international Fellowship within the European Social Fund 2014-2020 programme of Regione Autonoma Friuli Venezia Giulia to GB.
