description: Very high energy $γ$-rays have recently been detected from the microquasar LS I +61 303 using the MAGIC telescope. A phenomenological study on the concomitant neutrinos that would be radiated if the $γ$-ray emission is hadronic in origin is herein presented. Neutrino oscillations are considered, and the expected number of events in a km-scale detector such as ICECUBE is computed under different assumptions including orbital periodicity and modulation, as well as different precision in the modeling of the detector. We argue that the upper limits already imposed on the neutrino emission of LS I +61 303 using AMANDA-II and the forthcoming measurements by ICECUBE may significantly constrain -in an independent and unbiased way- the $γ$-ray to neutrino flux ratio, and thus the possibility of a hadronic origin of the $γ$-rays. The viability of hadronic models based on wind-jet interactions in the LS + 61 303 system after MAGIC measurements is discussed.

description: Subject of the incumbent thesis are the cases in which occur geometrical modifications in the status of operative Cadastre. In particular, the law itself makes provision for ways to rectify any errors made in the initial registrations, in order to restore any already existing errors but also upon circumstantial process there can be geometrical modifications under status of operative Cadastre. It is evident that springboard for geometrical modifications can be an administrative act, a training transaction or a verdict issue. In this thesis it is firstly analyzed extensively the case of geometrical modifications by the legal remedy of the submitted application of correction of geometrical data according to article 19 par. 2 of Law 2664/1998 before the head of the Cadastral Office. Following that, the case of geometrical modifications due to a verdict issue is analyzed, afterwards the case of declaratory ownership lawsuit by virtue of extraordinary adverse possession and that of property dispensing conduit

Una categoria linguistica ambigua: i preverbi ungheresi

Publisher: name: Studi Finno-Ugrici, n.s.
Year: 2021

description: Il preverbo rappresenta la categoria della lingua ungherese che ha il maggiore impatto sulla struttura argomentale e sulla semantica del verbo. Questo elemento linguistico formalmente ridotto è legato al verbo, in una frase neutrale in posizione preverbale (da qui il nome “preverbo”), comportandosi a volte come partecipante in un’operazione di composizione, altre volte come unità linguistica in causa in un processo morfologico di tipo derivazionale. Esibisce un comportamento sintattico ambiguo in quanto sembra far parte del sintagma verbale quando precede il verbo, ma ha anche la facoltà di muoversi all’interno della frase come un costituente autonomo. Ecco perché l’inquadramento dei preverbi rappresenta una delle questioni più dibattute nelle grammatiche ungheresi, come avremo modo di mostrare mettendo a confronto le proposte di classificazione dei due indirizzi di pensiero principali, quello tradizionalista e quello strutturalista.

description: We study the performance and limitations of a coherent interface between collective atomic states and single photons. A quantized spin-wave excitation of an atomic sample inside an optical resonator is prepared probabilistically, stored, and adiabatically converted on demand into a sub-Poissonian photonic excitation of the resonator mode. The measured peak single-quantum conversion efficiency of 0.84(11) and its dependence on various parameters are well described by a simple model of the mode geometry and multilevel atomic structure, pointing the way towards implementing high-performance stationary single-photon sources.

description: Η ραγδαία ανάπτυξη της τεχνολογίας αλλά και οι απαιτήσεις τόσο της κοινωνίας όσο και των εργοδοτών ωθούν τις εταιρίες στο να βρίσκουν διαρκώς τρόπους βελτιστοποίησης της παραγωγικότητας αλλά και της αποδοτικότητας των εργαζομένων. Έρευνες υποδεικνύουν ότι ειδικά στον τομέα της Πληροφορικής η ποικιλομορφία της ομάδας εργαζομένων, επιφέρει καλύτερα και ταχύτερα αποτελέσματα. Για αυτό το λόγο κάθε εταιρία φροντίζει να εμπλουτίσει το ανθρώπινο δυναμικό της με άτομα από διαφορετικές ομάδες όπως είναι οι κοινωνικές, οικονομικές, ηλικιακές με τη συμβολή και των δύο φύλων.

description: The rapid development of technology, the demands of society and employers push companies to find ways to optimize employee productivity and efficiency continually. Research indicates that especially in the field of IT, the diversity of the workforce brings better and faster results. For this reason, every company strives to enrich its human resources with individuals from different social, economic, age and gender groups. Under-representation of women was a major issue. In this thesis, we analyze the reasons why women do not choose the IT industry. Moreover, we developed a logistic model based on data collected from the Stack Overflow Questionnaire Platform, which estimates the gender from the preferences of (desirable and undesirable) programming technologies. In this way we essentially investigate whether the technological preferences characterize the gender

description: Deformations of conventional solids are described via elasticity, a classical field theory whose form is constrained by translational and rotational symmetries. However, flexible metamaterials often contain an additional approximate symmetry due to the presence of a designer soft strain pathway. Here we show that low energy deformations of designer dilational metamaterials will be governed by a novel field theory, conformal elasticity, in which the nonuniform, nonlinear deformations observed under generic loads correspond with the well-studied conformal maps. We validate this approach using experiments and finite element simulations and further show that such systems obey a holographic bulk-boundary principle, which enables an unprecedented analytic method to predict and control nonuniform, nonlinear deformations. This work both presents a novel method of precise deformation control and demonstrates a general principle in which mechanisms can generate special classes of soft deformations.

Quasi-local mass in the covariant Newtonian space-time

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: In general relativity, quasi-local energy-momentum expressions have been constructed from various formulae. However, Newtonian theory of gravity gives a well known and an unique quasi-local mass expression (surface integration). Since geometrical formulation of Newtonian gravity has been established in the covariant Newtonian space-time, it provides a covariant approximation from relativistic to Newtonian theories. By using this approximation, we calculate Komar integral, Brown-York quasi-local energy and Dougan-Mason quasi-local mass in the covariant Newtonian space-time. It turns out that Komar integral naturally gives the Newtonian quasi-local mass expression, however, further conditions (spherical symmetry) need to be made for Brown-York and Dougan-Mason expressions.

description: The aim of this research is to identify the core problem leading to children’s exclusion from urban planning processes for vulnerable settings and present recommendations for a way forward. The specific barriers and enablers to children’s participation are examined by studying the motivations of decision-makers responsible for urban planning processes through case studies in vulnerable settings. This data then is used to propose pathways to mainstreaming children’s participation. Ultimately the research is designed to position children as active citizens in civil society and to propose recommendations to mainstream children’s participation and agency in urban planning processes for vulnerable settings.

description: The success of learning with noisy labels (LNL) methods relies heavily on the success of a warm-up stage where standard supervised training is performed using the full (noisy) training set. In this paper, we identify a "warm-up obstacle": the inability of standard warm-up stages to train high quality feature extractors and avert memorization of noisy labels. We propose "Contrast to Divide" (C2D), a simple framework that solves this problem by pre-training the feature extractor in a self-supervised fashion. Using self-supervised pre-training boosts the performance of existing LNL approaches by drastically reducing the warm-up stage's susceptibility to noise level, shortening its duration, and improving extracted feature quality. C2D works out of the box with existing methods and demonstrates markedly improved performance, especially in the high noise regime, where we get a boost of more than 27% for CIFAR-100 with 90% noise over the previous state of the art. In real-life noise settings, C2D trained on mini-WebVision outperforms previous works both in WebVision and ImageNet validation sets by 3% top-1 accuracy. We perform an in-depth analysis of the framework, including investigating the performance of different pre-training approaches and estimating the effective upper bound of the LNL performance with semi-supervised learning.

description: Questo contributo si propone di esplorare e ritrarre non solo l’immagine del Felvidék (Alta Ungheria) nelle opere di Sándor Márai, ma anche il rapporto dello scrittore con la sua terra natale prima e dopo la firma del Primo arbitrato di Vienna il 2 novembre 1938. Particolare attenzione sarà dedicata ad un’analisi dettagliata delle sue complesse risposte emotive – come nostalgia, gioia, rassegnazione, delusione e disincanto – agli eventi storici e politici da un lato, e ai suoi pensieri ed esperienze evocati dalla riannessione di Felvidék dall’altro per comprendere l’equilibrio e la dialettica tra ragione e razionalità ed emozioni e stati affettivi nelle sue risposte. Verranno inoltre indagate e descritte le caratteristiche principali del suo discorso emotivo e delle parole che designano emozioni presenti nei suoi scritti pubblicati principalmente tra il 1938 e il 1939 insieme al suo concetto di ‘famiglia’ riferito alla grande famiglia di abitanti della regione che – secondo Márai – irresistibile, con movimenti naturali e con il mutismo causato dalla tensione interiore cominciò a prepararsi al ritorno in patria, cioè al ricongiungimento con il Regno d’Ungheria. Infine, questo contributo si focalizzerà anche sulle descrizioni dei paesaggi materiali e spirituali della regione contenute nei suoi scritti che toccano anche la sfera razionale ed emotiva.

description: This dissertation investigates both theoretically and empirically the common risk factors that systematically determine the form of the yield curve. Depending on yield curves, investors reshape their decisions about the distribution of their portfolio. Systematic risk factors take either the form of parallel shifts of the yield curve, or the form of slope shifts or the form of curvature shifts. A valuable part of this paper is the reference to the theoretical framework of factor analysis and of principal component analysis, namely the techniques that will develop so as to estimate these risk factors. The theoretical part concludes by presenting some of the real variables of the economies that are likely to approximate these factors. We develop the empirical part of the dissertation by executing factor analysis and principal component analysis. By selecting eight European countries with monthly interest rate data for the last 15 years, we draw conclusions on the estimated common risk factors and their respective loadings on the effect of the yield curve. The relative heterogeneity that characterizes these European bond markets arouses our interest, prompting us to empirically investigate various models for the emergence of more comprehensive and robust conclusions

description: Boolean satisfiability problems are an important benchmark for questions about complexity, algorithms, heuristics and threshold phenomena. Recent work on heuristics, and the satisfiability threshold has centered around the structure and connectivity of the solution space. Motivated by this work, we study structural and connectivity-related properties of the space of solutions of Boolean satisfiability problems and establish various dichotomies in Schaefer's framework. On the structural side, we obtain dichotomies for the kinds of subgraphs of the hypercube that can be induced by the solutions of Boolean formulas, as well as for the diameter of the connected components of the solution space. On the computational side, we establish dichotomy theorems for the complexity of the connectivity and st-connectivity questions for the graph of solutions of Boolean formulas. Our results assert that the intractable side of the computational dichotomies is PSPACE-complete, while the tractable side - which includes but is not limited to all problems with polynomial time algorithms for satisfiability - is in P for the st-connectivity question, and in coNP for the connectivity question. The diameter of components can be exponential for the PSPACE-complete cases, whereas in all other cases it is linear; thus, small diameter and tractability of the connectivity problems are remarkably aligned. The crux of our results is an expressibility theorem showing that in the tractable cases, the subgraphs induced by the solution space possess certain good structural properties, whereas in the intractable cases, the subgraphs can be arbitrary.

description: The few available French resources for evaluating linguistic models or algorithms on other linguistic levels than morpho-syntax are either insufficient from quantitative as well as qualitative point of view or not freely accessible. Based on this fact, the FREEBANK project intends to create French corpora constructed using manually revised output from a hybrid Constraint Grammar parser and annotated on several linguistic levels (structure, morpho-syntax, syntax, coreference), with the objective to make them available on-line for research purposes. Therefore, we will focus on using standard annotation schemes, integration of existing resources and maintenance allowing for continuous enrichment of the annotations. Prior to the actual presentation of the prototype that has been implemented, this paper describes a generic model for the organization and deployment of a linguistic resource archive, in compliance with the various works currently conducted within international standardization initiatives (TEI and ISO/TC 37/SC 4).

description: Here we present new - and, nevertheless, last - mid-infrared (mid-IR) data for supernovae (SNe) based on measurements with the Spitzer Space Telescope. Comparing our recent 3.6 and 4.5 $μ$m photometry with previously published mid-IR and further multiwavelength datasets, we were able to draw some conclusions about the origin and heating mechanism of the dust in these SNe or in their environments, as well as on possible connection with circumstellar matter (CSM) originating from pre-explosion mass-loss events in the progenitor stars. We also present new results regarding both certain SN classes and single objects. We highlight the mid-IR homogeneity of SNe Ia-CSM, which may be a hint of their common progenitor type and of their basically uniform circumstellar environments. Regarding single objects, it is worth highlighting the late-time interacting Type Ib SNe 2003gk and 2004dk, for which we present the first-ever mid-IR data, which seem to be consistent with clues of ongoing CSM interaction detected in other wavelength ranges. Our current study suggests that long-term mid-IR follow-up observations play a key role in a better understanding of both pre- and post-explosion processes in SNe and their environments. While Spitzer is not available any more, the expected unique data from the James Webb Space Telescope, as well as long-term near-IR follow-up observations of dusty SNe, can bring us closer to the hidden details of this topic.

description: Quantum transport simulations are rapidly evolving and now encompass well-controlled tensor network techniques for many-body limits. One powerful approach combines matrix product states with extended reservoirs. In this method, continuous reservoirs are represented by explicit, discretized counterparts and a chemical potential or temperature drop is maintained by external relaxation. Currents are strongly influenced by relaxation when it is very weak or strong, resulting in a simulation analog of Kramers' turnover for solution-phase chemical reactions. At intermediate relaxation, the intrinsic conductance, that given by the Landauer or Meir-Wingreen expressions, moderates the current. We demonstrate that strong impurity scattering (i.e., a small steady-state current) reveals anomalous transport regimes within this methodology at weak-to-moderate and moderate-to-strong relaxation. The former is due to virtual transitions and the latter to unphysical broadening of the populated density of states. Thus, the turnover analog has $five$ standard transport regimes, further constraining the parameters that lead to recovery of the intrinsic conductance. In the worst case, the common strategy of choosing a relaxation strength proportional to the reservoir level spacing can prevent convergence to the continuum limit. This advocates a simulation strategy where one utilizes the current versus relaxation turnover profiles to identify simulation parameters that most efficiently reproduce the intrinsic physical behavior.

description: The three-loop form factors in massless QCD can be expressed as a linear combination of master integrals. Besides a number of master integrals which factorise into products of one-loop and two-loop integrals, one finds 16 genuine three-loop integrals. Of these, six have the form of a bubble insertion inside a one-loop or two-loop vertex integral. We compute all master integrals with these insertion topologies.

A multiple period combined optimization approach to sawmill production planning systems
Creators: name: Norton, Scott Erling
Publisher: name: University of British Columbia
Year: 2008

description: Recent efforts on the development of production planning systems for sawmills have focused on combined optimization type solutions in a steady state market environment. This thesis focuses on developing a multiple period production planning system which responds to expected changes in product value or market demand by changing production policy, sawing policy, or log boom selection. Production periods are tied together by log and lumber inventory. The model was tested using four market scenarios on a large log mill producing export products. In general, it was shown that the model responded to market changes using sawing pattern selection and altered boom distribution and consumption.

description: Στόχος της παρούσας εργασίας είναι η ανάλυση των φαρμακευτικών ιδιοτήτων και των κλινικών χρήσεων της βαζοπρεσσίνης με γνώμονα τα κριτήρια της επιτροπής αξιολόγησης τεχνολογιών υγείας.Αναζητήθηκαν βιβλιογραφίες μέσω των μηχανών αναζήτησης Pubmed, SCOPUS και Cochrane για τυχαιοποιημένες κλινικές δοκιμές (RCTs) που αφορούν τη χρήση βαζοπρεσσίνης στο σηπτικό σοκ και όχι μελέτες με ανάλογα μόρια όπως η τερλιπρεσσίνη και η σελεπρεσσίνη. Επίσης,έχουν εξαιρεθεί μελετες που επιπροσθέτως στο σηπτικο σοκ υφίσταται και άλλη μία σοβαρή παθολογική κατάσταση όπως η κίρρωση ήπατος ή το ARDS.Τέλος, μελέτες που έχουν χρησιμοποιήσει τη βαζοπρεσσίνη ως μονοθεραπεία έχουν αποκλεισθεί καθώς δεν εναρμονίζονται με τα νεότερα επιστημονικά δεδομένα και τις πρόσφατες κατευθυντήριες οδηγίες.Έξι κλινικές μελέτες πληρούσαν τα προαναφερθέντα κριτήρια και συμπεριλήφθηκαν στην ανάλυση και περιγραφή με βάση το σύστημα ταξινόμησης Alhqvist-Rastad.Διαπιστώθηκε η υπεροχή της πρώιμης χρήσης βαζοπρεσσίνης στην αντιμετώπιση του σηπτικού σοκ ηπιότερης βαρύτητας.Στις λοιπές κατηγορίες σηπτικού σοκ η διαφορά θνητότητας μεταξύ των ομάδων δεν ήταν στατιστικώς σημαντική.Τέλος,συνοψίζοντας,η πρώιμη (εντός 6 ωρών) συγχορήγηση βαζοπρεσσίνης με κατεχολαμίνες οδηγεί σε: αύξηση της μέσης αρτηριακής πίεσης,μείωση της δόσης των κατεχολαμινών,μείωση της θνητότητας σε ασθενείς με λιγότερο σοβαρό σηπτικό σοκ και χαμηλότερο ποσοστό αρρυθμιών
description: Analysis of the pharmaceutical properties and the clinical uses of vasopressin according to the health technologies agency criteria.A Pubmed, SCOPUS and Cochrane search was conducted in order to locate randomized clinical trials regarding the use of vasopressin in septic shock rather than studies with analogues such as terlipressin and selepressin.Studies in which sepsis co-existed with other pathologies such as liver cirrhosis or ARDS were excluded.Finally, studies that have used vasopressin as a monotherapy have been ruled out because they are not in line with the latest scientific data and recent guidelines.Six clinical studies fulfilled the above criteria and were included in the analysis and description based on the Alhqvist-Rastad classification system. The early use of vasopressin in the treatment of milder septic shock had favourable outcomes.In other septic shock categories the mortality difference between the groups was not statistically significant.Finally, summarizing, early (within the first 6 hours) co-administration of vasopressin with catecholamines results in:increase in mean blood pressure,dose reduction of catecholamines, reduced mortality in patients with less severe septic shock and lower rate of arrhythmias

description: RES-NOVA is a new proposed experiment for the investigation of astrophysical neutrino sources with archaeological Pb-based cryogenic detectors. RES-NOVA will exploit Coherent Elastic neutrino-Nucleus Scattering (CE$ν$NS) as detection channel, thus it will be equally sensitive to all neutrino flavors produced by Supernovae (SNe). RES-NOVA with only a total active volume of (60 cm)$^3$ and an energy threshold of 1 keV will probe the entire Milky Way Galaxy for (failed) core-collapse SNe with $> 3 σ$ detection significance. The high detector modularity makes RES-NOVA ideal also for reconstructing the main parameters (e.g. average neutrino energy, star binding energy) of SNe occurring in our vicinity, without deterioration of the detector performance caused by the high neutrino interaction rate. For the first time, distances $<3$ kpc can be surveyed, similarly to the ones where all known past galactic SNe happened. We discuss the RES-NOVA potential, accounting for a realistic setup, considering the detector geometry, modularity and background level in the region of interest. We report on the RES-NOVA background model and on the sensitivity to SN neutrinos as a function of the distance travelled by neutrinos.

Για το σκοπό αυτό, αναπτύχθηκε ένα cluster υπολογιστών μικρής κλίμακας, που περιλαμβάνει 4 servers υψηλής απόδοσης που είναι διασυνδεδεμένοι με τη χρήση μονάδων οπτικής διασύνδεσης SFP + και αντίστοιχων διακοπτών. Η αρχιτεκτονική συμπλέγματος αποτελείται από έναν κύριο κόμβο που συνδέεται με τρεις κόμβους «σκλάβους», ενώ σε όλους αυτούς τους διακομιστές αναπτύχθηκε το πρωτόκολλο MPICH προκειμένου να εκτελεστούν διάφορα διαφορετικά benchmarks MPI, τα οποία αντιστοιχούν σε διάφορα φορτία εργασίας που προκύπτουν στα αναδυόμενα φορτία DC και HPC. Για την εκτέλεση της αξιολόγησης, η κυκλοφορία που ανταλλάχθηκε μεταξύ των εξυπηρετητών, κατά την εκτέλεση των φόρτων εργασίας, καταγράφηκε χρησιμοποιώντας το λογισμικό n2disk και ακολούθως μεταφέρθηκε στο Wireshark για σκοπούς ανάλυσης
description: The present thesis deals with the network performance evaluation and analysis of an optically interconnected high-end computing cluster, with the use of benchmarking workloads. For this purpose, a small-scale computing cluster was developed, comprising 4 high-performance rack-mounted servers that were interconnected with the use of optical interconnection SFP+ modules and respective switches. Our cluster architecture consists of a master node connecting to three slave nodes, while on all of these servers the MPICH protocol was deployed in order to run a number of different MPI Benchmarks, that correspond to various workloads encountered in emerging DC and HPC workloads. To perform the evaluation, the traffic exchanged between the servers, during the execution of the workloads, was captured using the n2disk software and then subsequently fed to Wireshark for analysis purposes
Hydrogen-Triggered Type I X-ray Bursts in a Two-Zone Model

description: We use the two-zone model of Cooper & Narayan to study the onset and time evolution of hydrogen-triggered type I X-ray bursts on accreting neutron stars. At the lowest accretion rates, thermally unstable hydrogen burning ignites helium as well and produces a mixed hydrogen and helium burst. For somewhat higher accretion rates, thermally unstable hydrogen burning does not ignite helium and thus triggers only a weak hydrogen flash. The peak luminosities of weak hydrogen flashes are typically much lower than the accretion luminosity. These results are in accord with previous theoretical work. We find that a series of weak hydrogen flashes generates a massive layer of helium that eventually ignites in an energetic pure helium flash. Although previously conjectured, this is the first time such bursting behavior has been actually demonstrated in a theoretical model. For yet higher accretion rates, hydrogen burning is thermally stable and thus steadily generates a layer of helium that ultimately ignites in a pure helium flash. We find that, for a narrow range of accretion rates between the mixed hydrogen and helium burst and weak hydrogen flash regimes, unstable hydrogen burning ignites helium only after a short series of weak hydrogen flashes has generated a sufficiently deep layer of helium. These bursts have fluences that are intermediate between those of normal mixed hydrogen and helium bursts and energetic pure helium flashes.

The emerging discourses of social, emotional and mental health and their impact on the lives of children

description:    
In 2014, the Special educational needs and disability code of practice: 0 to 25 years (DfE & DoH, 2015) introduced four broad areas of need to describe pupils who required special educational provision in England. One of these categories was Social, Emotional and Mental Health (SEMH). A narrative literature review revealed a paucity of research in this area. While the general language of special education and the impact of categorising children was the subject of interesting research, papers focused on SEMH had several shortcomings.
This thesis used the work of Michel Foucault to explore the emerging discourses of SEMH and their impact on the lives of children. Research was undertaken at an SEMH special school in England and activities were conducted as year 11 pupils prepared for the transition to post-16 education. Data were collected from teachers and parents via experiential focus groups. Data were collected from pupils via semi-formal interviews.  (Critical) discourse analysis was used to consider and compare the discourse used by pupils, parents and teachers when describing SEMH. Phenomenology was used to consider pupils’ experiences of this discourse.  The findings were conceptualised as a ‘Game of Truth’. 
The findings suggested that a clear and consistent discourse of SEMH does not yet exist. Instead, a myriad of voices contributed to a series of diverse discourses being simultaneously generated, applied, accepted, subverted and rejected. These discourses included those of difference, deviance, protection and trauma. There was evidence to suggest that elements of these discourses caused some pupils significant distress and contributed to feelings of anxiety and shame. An original model was used to illustrate the link between power, discourse and subjectivity and revealed some teachers and parents to be parrhesiastic truth-tellers. The work of Avery Gordon emerged as an effective and original way to theorise the haunting experienced by pupils and capture their desire for something to be done. A cautious recommendation is made to those working in SEMH special schools so that support is offered to pupils while further research is undertaken.

description: Neural networks serve as effective controllers in a variety of complex settings due to their ability to represent expressive policies. The complex nature of neural networks, however, makes their output difficult to verify and predict, which limits their use in safety-critical applications. While simulations provide insight into the performance of neural network controllers, they are not enough to guarantee that the controller will perform safely in all scenarios. To address this problem, recent work has focused on formal methods to verify properties of neural network outputs. For neural network controllers, we can use a dynamics model to determine the output properties that must hold for the controller to operate safely. In this work, we develop a method to use the results from neural network verification tools to provide probabilistic safety guarantees on a neural network controller. We develop an adaptive verification approach to efficiently generate an overapproximation of the neural network policy. Next, we modify the traditional formulation of Markov decision process (MDP) model checking to provide guarantees on the overapproximated policy given a stochastic dynamics model. Finally, we incorporate techniques in state abstraction to reduce overapproximation error during the model checking process. We show that our method is able to generate meaningful probabilistic safety guarantees for aircraft collision avoidance neural networks that are loosely inspired by Airborne Collision Avoidance System X (ACAS X), a family of collision avoidance systems that formulates the problem as a partially observable Markov decision process (POMDP).
