Half-integer Shapiro steps in highly transmissive InSb nanoflag Josephson junctions
We investigate a ballistic InSb nanoflag-based Josephson junction with Nb
superconducting contacts. The high transparency of the
superconductor-semiconductor interfaces enables the exploration of quantum
transport with parallel short and long conducting channels. Under microwave
irradiation, we observe half-integer Shapiro steps that are robust to
temperature, suggesting their possible non-equilibrium origin. Our results
demonstrate the potential of ballistic InSb nanoflags Josephson junctions as a
valuable platform for understanding the physics of hybrid devices and
investigating their non-equilibrium dynamics.Comment: 37 pages, 14 figure

Proceedings of the Fifth Italian Conference on Computational Linguistics CLiC-it 2018
On behalf of the Program Committee, a very warm welcome to the Fifth Italian Conference on Computational Linguistics (CLiC-‐it 2018). This edition of the conference is held in Torino. The conference is locally organised by the University of Torino and hosted into its prestigious main lecture hall “Cavallerizza Reale”. The CLiC-‐it conference series is an initiative of the Italian Association for Computational Linguistics (AILC) which, after five years of activity, has clearly established itself as the premier national forum for research and development in the fields of Computational Linguistics and Natural Language Processing, where leading researchers and practitioners from academia and industry meet to share their research results, experiences, and challenges
rf-SQUID measurements of anomalous Josephson effect
We discuss the response of an rf-SQUID formed by anomalous Josephson junctions embedded in a superconducting ring with a non-negligible inductance. We demonstrate that a properly sweeping in-plane magnetic field can cause both the total flux and the current circulating in the device to modulate and to behave hysteretically. The bistable response of the system is analyzed as a function of the anomalous phase shift at different values of the screening parameter, in order to highlight the parameter range within which a hysteretic behavior can be observed. The magnetic flux piercing the SQUID ring is demonstrated to further modulate the hysteretical response of the system. Moreover, we show that the anomalous phase shift can be conveniently determined through the measurement of the out-of-plane magnetic field at which the device switches to the voltage state and the number of trapped flux quanta changes. Finally, we compare the response of two different device configurations, namely, a SQUID including only one or two anomalous junctions. In view of these results, the proposed device can be effectively used to detect and measure the anomalous Josephson effect
Safety profile of SARS-CoV-2 vaccination in patients with antibody-mediated CNS disorders
Objectives: In this retrospective multicenter study, we evaluated the safety of SARS-CoV-2 vaccination in patients harboring autoantibodies targeting neuronal surface and/or synaptic antigens. Methods: From eight Italian Neurology Units, we included patients with: a) serum and/or CSF positivity for specific neuronal autoantibodies; b) a compatible neurological syndrome; and c) available follow-up ≥6 weeks after vaccination with any of the approved SARS-CoV-2 vaccines. Demographics, clinical data, and information regarding previous SARS-CoV-2 infection and vaccination were collected. Disease relapses were considered "post-infectious" or "post-vaccination" when occurring within 6 weeks from infection/vaccination. Results: We included 66 patients; 7/66 (11%) had a previous history of SARS-CoV-2 infection and 1/7 (14%) had post-infection relapses. BNT162b2-Pfizer-BioNTec was administered in 55 cases (83.3%) and mRNA-1273-Moderna in 11 (16.7%). The median number of doses administered per patient was 2 (1-3) and >50% of patients did not experience side effects. Five patients (8%) had post-vaccination relapses (seizure 3/5); 4/5 improved after immunotherapy, while one did not receive immunotherapy and worsened. Patients with post-vaccination relapses had higher disability scores at vaccination (p = 0.025), a trend favoring Leucine-rich glioma-inactivated protein 1 LGI1 glutamic acid decarboxylase 65 (GAD65) antibodies (p = 0.054) and shorter time from last relapse (p = 0.057). Discussion: Our data support the safety of SARS-CoV-2 vaccines in patients with neurological disorders associated with antibodies to neuronal and synaptic antigens
