Takotsubo Syndrome Associated with COVID-19
Get PDFObjective: The availability of public health information for optimised supportive care is critical during the COVID-19 pandemic. We describe the first case of COVID-19 complicated by Takotsubo cardiomyopathy.
Materials and Methods: We report the clinical, laboratory and radiological findings of a patient with severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2).
Results: The nasopharyngeal swab was positive for SARS-CoV-2 and x-ray images demonstrated pathognomonic pneumonia. The patient developed tachycardia and the echocardiogram confirmed the diagnosis of Takotsubo cardiomyopathy.
Conclusions: Doctors should be aware of the need to thoroughly study this new infection in order to understand its underlying mechanisms and related complications
Giant Lactating Adenoma – Size of a Shot Put Ball
Get PDFLactating adenomas are benign breast tumours which normally present in the peripartum period. Aetiology, pathogenesis, best diagnostic modality and management are not yet clear in the literature. We present a case of a 32-year-old pregnant patient who was re-referred to us with a progressively increasing left breast lesion, pre-existing prior to pregnancy, which was found to be a huge lactating adenoma

Between Magna Graecia and Rome: Towards An Archaeological Approach to Dance Performance in Cults
Get PDFSfM-photogrammetry for fast recording of archaeological features in remote areas
Get PDFDigital documenting of archaeological evidence represents a crucial tool in the study, preservation, management, and promotion of archaeological sites in remote regions and in fragile landscapes. In fact, in marginal environment, the knowledge related to archaeological heritage can quickly disappear, especially when policies to protect cultural heritage are unreliable or lacking. In the last few decades, archaeological fieldwork has seen the increasing use of Structure-from-Motion (SfM) photogrammetric technique as a tool for mapping and recording archaeological evidence. This technique allows the creation of highly detailed 3D models of archaeological sites, monuments, and artefacts from sets of simple but accurately taken pictures, thus preserving the data for further research or (digital) cultural valorisation. Nowadays, low-cost/commercial off-the-shelf sensors (professional and semi-professional digital cameras and smartphones as well) are widely available and accessible by most of the users operating in cultural heritage documentation. This has made the acquisition of field pictures in archaeological research much more flexible and cost-effective. 3D models obtained from these pictures through photogrammetric commercial software can be scaled with a known-measure providing highly detailed models for archaeological purposes. This enhances the ability of archaeologists to record archaeological features during field surveys and rapidly obtain 3D models. This is especially useful in the case of archaeological surveys carried out in remote and barely accessible areas. In this paper, we present the results of the application of the above-mentioned methods during archaeological surveys in the Sultanate of Oman, where several archaeological features have been recorded through SfM photogrammetry using commercial devices and portable scale-bars. We demonstrate that this is a highly-flexible and fast process to record archaeological heritage in low-accessible or fragile contexts, where a 3D model (with centimetric precision) represents a valuable dataset for further in-lab analysis and cultural dissemination
Geomorphometry 2020. Conference Proceedings
Get PDFGeomorphometry is the science of quantitative land surface analysis. It gathers various mathematical, statistical and image processing techniques to quantify morphological, hydrological, ecological and other aspects of a land surface. Common synonyms for geomorphometry are geomorphological analysis, terrain morphometry or terrain analysis and land surface analysis. The typical input to geomorphometric analysis is a square-grid representation of the land surface: a digital elevation (or land surface) model.
The first Geomorphometry conference dates back to 2009 and it took place in Zürich, Switzerland. Subsequent events were in Redlands (California), Nánjīng (China), Poznan (Poland) and Boulder (Colorado), at about two years intervals. The International Society for Geomorphometry (ISG) and the Organizing Committee scheduled the sixth Geomorphometry conference in Perugia, Italy, June 2020. Worldwide safety measures dictated the event could not be held in presence, and we excluded the possibility to hold the conference remotely. Thus, we postponed the event by one year - it will be organized in June 2021, in Perugia, hosted by the Research Institute for Geo-Hydrological Protection of the Italian National Research Council (CNR IRPI) and the Department of Physics and Geology of the University of Perugia.
One of the reasons why we postponed the conference, instead of canceling, was the encouraging number of submitted abstracts. Abstracts are actually short papers consisting of four pages, including figures and references, and they were peer-reviewed by the Scientific Committee of the conference. This book is a collection of the contributions revised by the authors after peer review. We grouped them in seven classes, as follows:
• Data and methods (13 abstracts)
• Geoheritage (6 abstracts)
• Glacial processes (4 abstracts)
• LIDAR and high resolution data (8 abstracts)
• Morphotectonics (8 abstracts)
• Natural hazards (12 abstracts)
• Soil erosion and fluvial processes (16 abstracts)
The 67 abstracts represent 80% of the initial contributions. The remaining ones were either not accepted after peer review or withdrawn by their Authors. Most of the contributions contain original material, and an extended version of a subset of them will be included in a special issue of a regular journal publication
A time-of-flight application for nuclear reactions at Coulomb energies
Get PDFThe Thick-Target Inverse Kinematics Resonant Scattering Method is an important tool for investigating resonances of the compound nucleus, spanning a wide center-of-mass energy range by using a single mono-energetic heavy-ion beam. The thick target can be solid (point-like) or gaseous. Anyhow, a limit of such a technique is related to the possible energy overlap of the same ejectile produced
by different reaction mechanisms. These ejectiles have different paths inside the target allowing Time-of-Flight (ToF) discrimination. Thus, in order to disentangle
different reaction channels and to get, for example, a clean elastic cross-section excitation function, a ToF event by event measurement can be performed in the case of gaseous targets. Several elastic scattering measurements on 4He gas targets were performed by using light ions. In this paper, the preliminary results of a heavy ion beam (A = 208) impinging on a 4He gas target at energies around the Coulomb barrier will be shown
Status of charged lepton flavour violation search with MEG II experiment
No full textThe MEG II experiment searches for the Charged Lepton Flavour Violating (CLFV) decay μ → eγ. This decay is foreseen by the Standard Model (SM) of Particle Physics at non-observable rates through neutrino oscillation. Observing it would be a clear signal of new physics (e.g., SUSY-GUT). After publishing the current upper limit to the Branching Ratio (BR) of this decay in 2016, BR(μ+ → e+γ) < 4.2 × 10−13, the MEG experiment started the upgrade of its detectors in order to increase the sensitivity by a factor 10, starting the MEG II phase. The aim of this work is to report a description of the new detectors design and performances, to present the results obtained in the 2018 pre-engineering run with all the new MEG II detectors installed, and to report on the current status of the
experiment and its future prospects
Measurements of the CKM angle γ at LHCb
No full textThe angle γ is the only complex phase of the Cabibbo-KobayashiMaskawa (CKM) matrix that can be measured at tree level. It therefore establishes a benchmark of the Standard Model (SM) against which loop-level measurements of the CKM parameters can be tested in order to reveal the presence of new physics. The LHCb experiment can determine γ from the analysis of both time-integrated and differential decay rates of B to D mesons. The combination of LHCb measurements represents the most precise determination of γ as of today and is going to reach the sub degree level of precision for a single measurement with the upgrade of the experiment
GEM detectors characterisation for the upgrade of the CMS muon system
No full textDuring its second running period (Run 2), the Large Hadron Collider (LHC) has delivered an instantaneous luminosity up to 2 × 1034 cm−2s−1. In the Long Shutdown 2 (LS2) the accelerator complex will be upgraded for the next Run 3 and in preparation for the High-Luminosity LHC (HL-LHC) which will operate at instantaneous luminosities of 5 × 1034 cm−2s−1 up to 7.5 × 1034 cm−2s−1 starting from 2025. To handle the high expected background rates and to improve the trigger capabilities keeping the trigger rate at an acceptable level, the forward muon system of the Compact Muon Solenoid (CMS) experiment will be upgraded with Gas Electron Multiplier (GEM) and Resistive Plate Chamber (RPC) detectors. In 2019 the first endcap of triple-GEM detectors has been installed in the first station of the muon detector (GE1/1), while a the second endcap is going to be installed in 2020. A second station of triple-GEM detectors named GE2/1 will be installed in
2021–2022. We will present an overview of the CMS muon detector upgrade with triple-GEM detectors: the production and quality control of the 144 triple-GEM detectors for the first station and the final validation of the GE1/1 chambers before installation
