    Abstract The ICARUS collaboration employed the 760-ton T600 detector in a successful 3-year physics run at the underground LNGS laboratory, performing a sensitive search for LSND-like anomalous νe\nu _e ν e appearance in the CERN Neutrino to Gran Sasso beam, which contributed to the constraints on the allowed neutrino oscillation parameters to a narrow region around 1 eV 2^2 2 . After a significant overhaul at CERN, the T600 detector has been installed at Fermilab. In 2020 the cryogenic commissioning began with detector cool down, liquid argon filling and recirculation. ICARUS then started its operations collecting the first neutrino events from the booster neutrino beam (BNB) and the Neutrinos at the Main Injector (NuMI) beam off-axis, which were used to test the ICARUS event selection, reconstruction and analysis algorithms. ICARUS successfully completed its commissioning phase in June 2022. The first goal of the ICARUS data taking will be a study to either confirm or refute the claim by Neutrino-4 short-baseline reactor experiment. ICARUS will also perform measurement of neutrino cross sections with the NuMI beam and several Beyond Standard Model searches. After the first year of operations, ICARUS will search for evidence of sterile neutrinos jointly with the Short-Baseline Near Detector, within the Short-Baseline Neutrino program. In this paper, the main activities carried out during the overhauling and installation phases are highlighted. Preliminary technical results from the ICARUS commissioning data with the BNB and NuMI beams are presented both in terms of performance of all ICARUS subsystems and of capability to select and reconstruct neutrino events

    Full Digital Workflow for Mandibular Ameloblastoma Management: Showcase for Technical Description

    No full text
    This is a showcase for technical description of a full digital workflow aimed to reconstruct and prosthetically rehabilitate the mandible after surgical resection. The surgery was performed following a computer-aided design and computer-aided manufacturing (CAD-CAM) guided workflow, using 3D reconstruction of the mandible and the fibula. After 2 years, when the ossification of the flap was reached and verified by a computed tomography (CT) scan, surgery was performed using a two-step implant rehabilitation, with successful outcomes

    Large intraoral Lipoma: A case report of rare neoformation of the lower lip

    No full text
    Lipoma is a common soft tissue benign neoplasm originating from the mesenchymal cells of connective tissue. It is a painless neoplasm characterized by slow growth. The incidence in the oral cavity is relatively rare (1–4%). A predisposing cause of the onset in the oral cavity is the continuous trauma due to the action of the teeth. Patients can live with an oral lipoma for several years before experiencing symptoms that usually coincide with speech and chewing disorders. We report a case of unusual, intraoral lip lipoma that caused discomfort to the patient. Case Report: A 72 years old man presented a soft mass in the mucous membrane of the lower lip. The patient reported that he noted the lesion for about 5 years but he decided to treat this condition after a long period since he developed discomfort during speaking and chewing. The patient underwent surgical excision of the lesion, which was then sent for histological examination. Results confirmed the initial hypothesis of lipoma. Conclusions: Lipomas of the oral cavity are slow-growing neoformations that patients usually underestimate or tolerate until they feel disturbances, especially in speaking and chewing, or if they create aesthetic problems. Although lipoma represents a benign condition surgical excision should be recommended and histopathological examination is necessary to confirm the diagnosis

    Search for Highly-Ionizing Particles in pp Collisions During LHC Run-2 Using the Full MoEDAL Detector

    No full text
    International audienceThis search for Magnetic Monopoles (MMs) and High Electric Charge Objects (HECOs) with spins 0, 1/2 and 1, uses for the first time the full MoEDAL detector, exposed to 6.6 fb^-1 proton-proton collisions at 13 TeV. The results are interpreted in terms of Drell-Yan and photon-fusion pair production. Mass limits on direct production of MMs of up to 10 Dirac magnetic charges and HECOs with electric charge in the range 5e to 350e were achieved. The charge limits placed on MM and HECO production are currently the strongest in the world. MoEDAL is the only LHC experiment capable of being directly calibrated for highly-ionizing particles using heavy ions and with a detector system dedicated to definitively measuring magnetic charge

    Problematising Local Indigenous Community Research

    Get PDF
    This book deliberates on developments related to Knowledge Pathing: Multi-, Inter- and Trans-Disciplining in Social Sciences. The book explores the value of this vexed concept in advancing the course for multi-, inter- and trans-disciplinary perspectives, methodologies, theories and epistemologies of knowledge pathing. The discourse on knowledge pathing remains critical in advancing debates and dialogues in the humanities and social sciences spaces of research and studies. This book makes a significant contribution to the scholarly understanding of indigenous knowledge research by focusing on problematising local indigenous community research from Afro-sensed perspectives. The field of indigenous knowledge research and higher education in Africa is complex. Yet, across the continent, higher education has been the sector to least embrace Indigenous Knowledge Systems (IKS) or regard indigenous science as a legitimate source of inspiration for the development of youth and local communities. Higher education institutions and local indigenous communities should thus generate knowledge and power through research. On the other hand, higher education researchers should use their research processes and skills for cross-beneficiation when engaging local indigenous communities. This book embodies the current discourse on decolonisation and the use of indigenous knowledge in research and is intended for research specialists in the field of indigenous knowledge systems
