Abstract

Abstract The NA62 experiment reports the branching ratio measurement BR K + → π + ν ν ¯ = 10.6 − 3.4 + 4.0 stat ± 0.9 syst × 10 − 11 $$ \mathrm{BR}\left({K}^{+}\to {\pi}^{+}\nu \overline{\nu}\right)=\left({10.6}_{-3.4}^{+4.0}\left|{}_{\mathrm{stat}}\right.\pm {0.9}_{\mathrm{syst}}\right)\times {10}^{-11} $$ at 68% CL, based on the observation of 20 signal candidates with an expected background of 7.0 events from the total data sample collected at the CERN SPS during 2016–2018. This provides evidence for the very rare K + → π + ν ν ¯ $$ {\pi}^{+}\nu \overline{\nu} $$ decay, observed with a significance of 3.4σ. The experiment achieves a single event sensitivity of (0.839 ± 0.054) × 10 −11, corresponding to 10.0 events assuming the Standard Model branching ratio of (8.4 ± 1.0) × 10 −11. This measurement is also used to set limits on BR(K + → π + X), where X is a scalar or pseudo-scalar particle. Details are given of the analysis of the 2018 data sample, which corresponds to about 80% of the total data sample.

Abstract

Introduction: Charged Particle Therapy plays a key role in the treatment of deep-seated tumours, because of the advantageous energy deposition culminating in the Bragg peak. However, knowledge of the dose delivered in the entrance channel is limited by the lack of data on the beam and fragmentation of the target. Methods: The FOOT experiment has been designed to measure the cross sections of the nuclear fragmentation of projectile and target with two different detectors: an electronic setup for the identification of Z ≥ 3 fragments and a nuclear emulsion spectrometer for Z ≤ 3 fragments. In this paper, we analyze the data taken by exposing four nuclear emulsion spectrometers, with C and C₂H₄ targets, to 200 MeV/n and 400 MeV/n oxygen beams at GSI Helmholtzzentrum für Schwerionenforschung (Darmstadt, Germany), and we report the charge identification of produced fragments based on the controlled fading induced on nuclear emulsion films. Results: The goal of identifying fragments as heavy as lithium has been achieved. Discussion: The results will contribute to a better understanding of the nuclear fragmentation process in charged particle therapy and have implications for refining treatment planning in the presence of deep-seated tumors.

Abstract

Searches for lepton number violating K+→π−e+e+ and K+→π−π0e+e+ decays have been performed using the complete dataset collected by the NA62 experiment at CERN in 2016–2018. Upper limits of 5.3×10−11 and 8.5×10−10 are obtained on the decay branching fractions at 90% confidence level. The former result improves by a factor of four over the previous best limit, while the latter result represents the first limit on the K+→π−π0e+e+ decay rate.

Abstract

Il fratino (Charadrius alexandrinus, Charadriformes) è una specie con distribuzione ampia che comprende i litorali di tutta la fascia temperata e subtropicale di Europa, Asia ed Africa. Negli ultimi decenni la disponibilità di habitat per la nidificazione della specie è risultata fortemente limitata dalla distruzione diretta o perdita funzionale delle aree dunali ad opera del crescente turismo costiero. Quando non è preclusa la possibilità di insediarsi sul litorale, il successo riproduttivo risulta comunque drasticamente ridotto dal disturbo antropico. In Italia, il fratino è in forte diminuzione ed è classificato “In Pericolo” nella Lista Rossa dei vertebrati italiani. Tre nuclei stabili sono noti in Toscana, di cui uno nel comune di Castagneto Carducci (Livorno). In quest’area, il recupero di un uovo fratturato a seguito di una forte mareggiata (2020) sull’arenile della Zona Speciale di Conservazione/Zona di Protezione Speciale Padule di Bolgheri, ha permesso l’amplificazione tramite PCR di un frammento di 523 pb della Regione di Controllo del DNA mitocondriale. La sequenza è stata allineata con altre 198 scaricate dalla GenBank al fine di ricostruire le relazioni genetiche tra fratini sulla base sia dell’origine geografica che dell’appartenenza a popolazioni continentali o insulari, identificare gruppi geneticamente omogenei, e testare un’ipotesi di espansione demografica attraverso l’intero areale di distribuzione della specie. La diversità genetica è risultata più elevata nelle isole rispetto alle aree continentali. Dei 47 aplotipi (H) totali, 35 sono privati mentre tra i rimanenti, tutti condivisi da più popolazioni, due si sono distinti per elevata frequenza: uno (H3) è stato quasi esclusivamente rinvenuto in Europa mentre l’altro (H14) nell’intera Eurasia (con prevalenza orientale). Il fratino di Bolgheri è stato assegnato all’aplotipo H3 insieme a soggetti originari soprattutto della Penisola Iberica e della Macaronesia. Nel complesso, tre gruppi genetici omogenei sono stati identificati nell’intero areale della specie; tuttavia, a conferma di un elevato flusso genico intraspecifico, nessuno di questi possiede una definita struttura spaziale. Infine, le analisi demografiche hanno evidenziato una significativa espansione demografica su scala continentale nella storia naturale del fratino. Questo studio rappresenta il primo contributo alla conoscenza delle affinità genetiche della popolazione italiana di fratino e sottolinea l’urgenza di investigare la specie su scala nazionale per definire strategie di conservazione più adeguatamente informate.

Abstract

We investigate the notion of orchestrated compliance for client/server interactions in the context of session contracts. Devising the notion of orchestrator in such a context makes it possible to have orchestrators with unbounded buffering capabilities and at the same time to guarantee any message from the client to be eventually delivered by the orchestrator to the server, while preventing the server from sending messages which are kept indefinitely inside the orchestrator. The compliance relation is shown to be decidable by means of 1) a procedure synthesising the orchestrators, if any, making a client compliant with a server, and 2) a procedure for deciding whether an orchestrator behaves in a proper way as mentioned before., Comment: In Proceedings ICE 2015, arXiv:1508.04595

Abstract

Abstract A search for the K + → π + X decay, where X is a long-lived feebly interacting particle, is performed through an interpretation of the K + → π + ν ν ¯ $$ {\pi}^{+}\nu \overline{\nu} $$ analysis of data collected in 2017 by the NA62 experiment at CERN. Two ranges of X masses, 0–110 MeV/c 2 and 154–260 MeV/c 2, and lifetimes above 100 ps are considered. The limits set on the branching ratio, BR(K + → π + X), are competitive with previously reported searches in the first mass range, and improve on current limits in the second mass range by more than an order of magnitude.

Abstract

The management of meningioma in elderly patients (MEP) presents a complex and evolving challenge. Data available offer conflicting information on treatment options and complications. This survey aimed to examine the current approach to MEP, comparing the national profile to data in the current literature. A survey addressing the treatments options and management of meningioma in elderly was designed on behalf of SINch® (Società Italiana di Neurochirurgia) and sent via email to all Chiefs of Neurosurgical Departments. The survey remained open for responses from May 5th, 2022, until November 21st, 2022. A search of the literature published between January 2000 and March 2023, in accordance to PRISMA guidelines, was included. A total of 51 Neurosurgical centers participated in the survey. The caseload profile of each center influences the choice of treatment selection (Stereotactic Radiosurgery versus open surgery) (p = 0.01) and the consolidated practice of discussing cases within a multidisciplinary group (p = 0.02). The pooled meta-analysis demonstrated a significant increased risk in the elderly group for permanent deficits (p < 0.00001), postoperative infections (p = 0.0004) and hemorrhage (p = 0.0001), perioperative mortality (p < 0.00001), and medical complications (p < 0.00001) as compared to the young population. This study presents the initial comprehensive analysis of the existing trends in the surgical management of MEP in Italy. The significant variation in practices primarily stems from the absence of standardized guidelines. While most centers have adopted an integrated approach, there is a need to promote a multidisciplinary care model. Prospective studies are needed to gather robust evidence in this clinical setting.

Abstract

In the setting of session behaviours, we study an extension of the concept of compliance when a disciplined form of backtracking is present. After adding checkpoints to the syntax of session behaviours, we formalise the operational semantics via a LTS, and define a natural notion of checkpoint compliance. We then obtain a co-inductive characterisation of such compliance relation, and an axiomatic presentation that is proved to be sound and complete. As a byproduct we get a decision procedure for the new compliance, being the axiomatic system algorithmic., Comment: In Proceedings BEAT 2014, arXiv:1408.5564

Abstract

Abstract The NA62 experiment reports an investigation of the K + → π + ν ν ¯ $$ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $$ mode from a sample of K + decays collected in 2017 at the CERN SPS. The experiment has achieved a single event sensitivity of (0.389 ± 0.024) × 10 −10, corresponding to 2.2 events assuming the Standard Model branching ratio of (8.4 ± 1.0) × 10 −11. Two signal candidates are observed with an expected background of 1.5 events. Combined with the result of a similar analysis conducted by NA62 on a smaller data set recorded in 2016, the collaboration now reports an upper limit of 1.78 × 10 −10 for the K + → π + ν ν ¯ $$ {K}^{+}\to {\pi}^{+}\nu \overline{\nu} $$ branching ratio at 90% CL. This, together with the corresponding 68% CL measurement of ( 0.48 − 0.48 + 0.72 $$ {0.48}_{-0.48}^{+0.72} $$ ) × 10 −10, are currently the most precise results worldwide, and are able to constrain some New Physics models that predict large enhancements still allowed by previous measurements.

Abstract

Introduction: Traumatic brain injury (TBI) represents a severe pathology with important social and economic concerns, decompressive craniectomy (DC) represents a life-saving surgical option to treat elevated intracranial hypertension (ICP). The rationale underlying DC is to remove part of the cranial bones and open the dura mater to create space, avoiding secondary parenchymal damage and brain herniations. The scope of this narrative review is to summarize the most relevant literature and to discuss main issues about indication, timing, surgical procedure, outcome, and complications in adult patients involved in severe traumatic brain injury, underwent to the DC. The literature research is made with Medical Subject Headings (MeSH) terms on PubMed/MEDLINE from 2003 to 2022 and we reviewed the most recent and relevant articles using the following keywords alone or matched with each other: decompressive craniectomy; traumatic brain injury; intracranial hypertension; acute subdural hematoma; cranioplasty; cerebral herniation, neuro-critical care, neuro-anesthesiology. The pathogenesis of TBI involves both primary injuries that correlate directly to the external impact of the brain and skull, and secondary injuries due to molecular, chemical, and inflammatory cascade inducing further cerebral damage. The DC can be classified into primary, defined as bone flap removing without its replacement for the treatment of intracerebral mass, and secondary, which indicates for the treatment of elevated intracranial pressure (ICP), refractory to intensive medical management. Briefly, the increased brain compliance following bone removal reflects on CBF and autoregulation inducing an alteration in CSF dynamics and so, eventual complications. The risk of complications is estimated around 40%. The main cause of mortality in DC patients is due to brain swelling. In traumatic brain injury, primary or secondary decompressive craniectomy is a life-saving surgery, and the right indication should be mandatory in multidisciplinary medical–surgical consultation.

135. Loosening the notions of compliance and sub-behaviour in client/server systems

Author

Barbanera, Franco and Liguoro, Ugo de'

Subjects
Computer Science - Logic in Computer Science
Abstract

In the context of "session behaviors" for client/server systems, we propose a weakening of the compliance and sub-behaviour relations where the bias toward the client (whose "requests" must be satisfied) is pushed further with respect to the usual definitions, by admitting that "not needed" output actions from the server side can be "skipped" by the client. Both compliance and sub-behaviour relations resulting from this weakening remain decidable, though the proof of the duals-as-minima property for servers, on which the decidability of the sub-behaviour relation relies, requires a tighter analysis of client/server interactions., Comment: In Proceedings ICE 2014, arXiv:1410.7013

136. Characterisation of Strongly Normalising lambda-mu-Terms

Computer Science - Logic in Computer Science, F.3.2
Abstract

We provide a characterisation of strongly normalising terms of the lambda-mu-calculus by means of a type system that uses intersection and product types. The presence of the latter and a restricted use of the type omega enable us to represent the particular notion of continuation used in the literature for the definition of semantics for the lambda-mu-calculus. This makes it possible to lift the well-known characterisation property for strongly-normalising lambda-terms - that uses intersection types - to the lambda-mu-calculus. From this result an alternative proof of strong normalisation for terms typeable in Parigot's propositional logical system follows, by means of an interpretation of that system into ours., Comment: In Proceedings ITRS 2012, arXiv:1307.7849

Abstract

Scheduled to launch in late 2021,the Imaging X-ray Polarimetry Explorer (IXPE) is a Small Explorer Mission designed to open up a new window of investigation --X-ray polarimetry. The IXPE observatory features 3 identical telescopes each consisting of a mirror module assembly with a polarization-sensitive imaging x-ray detector at its focus. An extending boom, deployed on orbit, provides the necessary 4 m focal length. The payload sits atop a 3-axis stabilized spacecraft which, among other things, provides power, attitude determination and control, commanding, and telemetry to the ground. During its 2-year baseline mission, IXPE will conduct precise polarimetry for samples of multiple categories of x-ray sources, with follow-on observations of selected targets. IXPE is a partnership between NASA and the Italian Space Agency (ASI).

Abstract

Barbaneraa Abstract This proposal wishes to discuss the main results of a qualitative investigation focalized on the theme of vaccine hesitancy, tackled on the basis of a large number of "remotely" conducted focused interviews. This work's primary objective is that of carrying out a methodological evaluation through which the strengths and weaknesses of the investigation tools employed may be clarified, in consideration of both the reference participants, as well as the online transposition of interactions which are traditionally actualized in person. The focused interviews represent the empirical base from which multiple and significant methodological observations became achievable. The online context in which they took place had a positive impact on the established ambience, it broadened its geographical reach, and fruitfully affected the fidelity of the collected information. As a preview of some of the surfaced insights, some of the advantages include: many of the participants reached expressed their opinion on the vaccination campaign in a particularly spontaneous, uninhibited and truthful manner; they dwelled on the conduct adopted during the pandemic, as well as on attitudes and emotional states attributable to dimensions like contagion, civic responsibility towards those close to them, the social consequences of refusing the vaccine, their relationship with the traditional science of medicine and the establishment by and large. Equally complex is the spectrum of disadvantages, among which are the lack of consent by some subjects to audio-video recording of the interview, the pronounced reluctance to discuss personal problems on part of those participants less accustomed to the use of digital devices, or those who appeared to be visibly uncomfortable before a screen.

Abstract The results of a search for π 0 decays to a photon and an invisible massive dark photon at the NA62 experiment at the CERN SPS are reported. From a total of 4.12 × 108 tagged π 0 mesons, no signal is observed. Assuming a kinetic-mixing interaction, limits are set on the dark photon coupling to the ordinary photon as a function of the dark photon mass, improving on previous searches in the mass range 60–110 MeV/c 2. The present results are interpreted in terms of an upper limit of the branching ratio of the electro-weak decay π 0 → γ ν ν ¯ $$ {\pi}^0\to \gamma \nu \overline{\nu} $$ , improving the current limit by more than three orders of magnitude.

Abstract

The NA62 experiment at the CERN SPS reports the first search for K+→π+νν¯ using the decay-in-flight technique, based on a sample of 1.21×1011 K+ decays collected in 2016. The single event sensitivity is 3.15×10−10, corresponding to 0.267 Standard Model events. One signal candidate is observed while the expected background is 0.152 events. This leads to an upper limit of 14×10−10 on the K+→π+νν¯ branching ratio at 95% CL.
