description: Uploadfilter sind derzeit Gegenstand der öffentlichen Diskussion. Dabei wird in erster Linie über ihren erwünschten Einsatz und ihre Wirkung gesprochen, aber kaum über ihre technischen Hintergründe. Wir beleuchten daher die Verfahren, die Uploadfilter ermöglichen und vergleichen rechtliche Vorgaben mit technischen Eigenschaften. Insbesondere betrachten wir die Vorgabe, dass Ausschnitte von Audio und Video von mehr als 15 Sekunden Länge erkannt werden sollen und zeigen auf, welchen Interpretationsspielraum diese Vorgabe mit sich bringt. Denn für die Performanz der Verfahren ist es von großer Bedeutung, ob die 15 Sekunden zusammenhängend sein müssen oder nicht.

description: We present three different methods to estimate error bars on the predictions made using a neural network. All of them represent lower bounds for the extrapolation errors. For example, we did not include an analysis on robustness against small perturbations of the input data. At first, we illustrate the methods through a simple toy model, then, we apply them to some realistic cases related to nuclear masses. By using theoretical data simulated either with a liquid-drop model or a Skyrme energy density functional, we benchmark the extrapolation performance of the neural network in regions of the Segrè chart far away from the ones used for the training and validation. Finally, we discuss how error bars can help identifying when the extrapolation becomes too uncertain and thus unreliable

description: Interpreting the evidence found at a crime scene is essential in reconstructing the circumstances of a crime and, hence, solving it. In this paper a classical hypothesis-driven approach is combined with computer-aided modeling. Hereby, the paper focuses on the advantages of 3D models and their added value in the reconstruction of a case by visually supporting the analysis of evidence found at a crime scene. Using the example of blood patterns, it is explained what the static part of an evidence is and how the interpretation of this part, with the help of an interpretation function, results in additional information about the dynamic part of evidence. Further it is explained how this concept can assist the classical hypothesis-driven approach of reconstructing a crime. By using 3D models it is possible to improve the analysis of the formation of evidence and especially the time line. Thus, 3D-models can aid classical forensic casework with a new computer-based approach.

description: Gegenstand der vorliegenden Masterarbeit ist das Kebabnorsk. Diese norwegische Jugendsprache wurde zum ersten Mal 1995 in einer norwegischen Hochschulschrift durch Stine Cecille Aasheim sprachwissenschaftlich behandelt. Das Kebabnorsk ist ein modernes Sprachphänomen, dass in der Hauptstadt Oslo zu finden. Ich bin durch Zufall auf diese Sprache aufmerksam geworden, als ich über norwegische Dialekte recherchierte, welche ich ursprünglich als mein Masterarbeitsthema behandeln wollte. Schnell stellte ich fest, dass bei diesem Sprachphänomen gehöriges Forschungspotenzial besteht, weil in der deutschsprachigen Forschungsliteratur das Kebabnorsk oftmals nur eine kurze Erwähnung findet. Damit bildet diese Masterarbeit den Anfang für eine sprachwissenschaftliche Behandlung in deutscher Sprache mit dem Schwerpunkt, es im Rahmen der Kontaktsprachenforschung zu behandeln. Folglich konzentrieren sich meine Bemühungen darauf, die Funktionalität der Sprache sowie dessen Status als Sprache zu erfassen.
description: The subject of this master’s thesis is Kebabnorsk. This Norwegian youth language first received linguistic attention in an academic thesis in 1995 by Stine Cecille Aasheim. Kebabnorsk is a modern language phenomenon which can be found Oslo. I came across this language through coincidence while conducting research on Norwegian dialects, which I initially planned to cover as my master’s thesis subject. I quickly ascertained a pertinent research potential, as Kebabnorsk only receives brief mentions in German research literature. Thus, this dissertation constitutes the starting point of a linguistic discussion in German within the scope of contact linguistics. Therefore, my efforts will concentrate on the language’s functionality and assess its status as a language.

description: The morphology of galaxies provide us with a unique tool for relating and understanding other physical properties and their changes over the course of cosmic time. It is only recently that we have been afforded access to a wealth of data for an unprecedented number galaxies thanks to large and deep surveys, We present the morphological catalogue of the OTELO survey galaxies detected with the Hubble Space Telescope (HST)-ACS F814W images. We explore various methods applied in previous works to separate early-type (ET) and late-type (LT) galaxies classified via spectral energy distribution (SED) fittings using galaxy templates. Together with this article, we are releasing a catalogue containing the main morphological parameters in the F606W and F814W bands derived for more than 8\,000 sources. The morphological analysis is based on the single-Sérsic profile fit. We used the GALAPAGOS2 software to provide multi-wavelength morphological parameters fitted simultaneously in two HST-ACS bands. The GALAPAGOS2 software detects, prepares guess values for GALFTI-M, and provides the best-fitting single-Sérsic model in both bands for each source. Stellar masses were estimated using synthetic rest-frame magnitudes recovered from SED fittings of galaxy templates. The morphological catalogue is complemented with concentration indexes from a separate SExtractor dual, high dynamical range mode. A total of 8,812 sources were successfully fitted with single-Sérsic profiles. The analysis of a carefully selected sample of ~3,000 sources up to phot_z=2 is presented in this work, of which 873 sources were not detected in previous studies. We found no statistical evidence for the evolution of the low-mass end of mass-size relation for ET and LT since z=2. Furthermore, we found a good agreement for the median size evolution for ET and LT galaxies, for a given stellar mass, with the data from the literature.

description: Asteroid Impacts pose a major threat to all life on the Earth. Deflecting the asteroid from the impact trajectory is an important way to mitigate the threat. A kinetic impactor remains to be the most feasible method to deflect the asteroid. However, due to the constraint of the launch capability, an impactor with the limited mass can only produce a very limited amount of velocity increment for the asteroid. In order to improve the deflection efficiency of the kinetic impactor strategy, this paper proposed a new concept called the Assembled Kinetic Impactor (AKI), which is combining the spacecraft with the launch vehicle final stage. By making full use of the mass of the launch vehicle final stage, the mass of the impactor will be increased, which will cause the improvement of the deflection efficiency. According to the technical data of Long March 5 (CZ-5) launch vehicle, the missions of deflecting Bennu are designed to demonstrate the power of the AKI concept. Simulation results show that, compared with the Classic Kinetic Impactor (CKI, performs spacecraft-rocket separation), the addition of the mass of the launch vehicle final stage can increase the deflection distance to more than 3 times, and reduce the launch lead-time by at least 15 years. With the requirement of the same deflection distance, the addition of the mass of the launch vehicle final stage can reduce the number of launches to 1/3 of that of the number of CKI launches. The AKI concept makes it possible to defend Bennu-like large asteroids by a no-nuclear technique within 10-year launch lead-time. At the same time, for a single CZ-5, the deflection distance of a 140 m diameter asteroid within 10-year launch lead-time, can be increased from less than 1 Earth radii to more than 1 Earth radii.

description: As China grows as a global power, so have expectations for it to behave 'responsibly'. Crucially, this has prompted intense debates - both inside and outside of the People's Republic - on its newfound roles and responsibilities in managing world affairs. Paralleling broader trends in international relations where a distinctive language of responsibility has come to permeate the conduct of world politics, these past few years have seen the Chinese leadership vigorously attempting to project a more 'responsible' image of the country. Yet whilst recasting its identity from an outlier of international society to that of a constructive stakeholder has served, in part, to reassure the global community of its intentions, doing so has also given rise to further questions on the nature of China's obligations and, more specifically, what it means to be 'responsible'. The central purpose of the thesis, as such, is to uncover how China understands and acts upon notions of responsibility in the realm of global governance. In particular, it examines China's engagement with extant structures of ecological governance, with special focus directed to how Chinese attitudes toward responsible stewardship have informed its practices in managing natural disasters and transboundary water resources. Taken together with the concepts of legitimacy and reciprocity, the concept of responsibility, as a fundamental idea undergirding governing processes, is seen to exert both a regulative and constitutive 'power' over actors. Of particular importance here is the 'politics of responsibility' - or to be precise, the socio-political dynamics of defining, designating, and demonstrating responsibility involved in determining the normative content of conceptions of responsibility as well as the agents tasked with the obligation to act. Occurring both within and between states, it is through these interlocking processes that notions of responsibility relate directly to efforts at governing the globe. How the People's Republic interprets and actualises conceptions of responsibility is, therefore, contingent not simply on the context at hand but on the broader politics of responsibility which, in the Chinese case, operates at multiple levels and is animated by a complex cast of local, national, regional and international actors. Connected through interweaving webs of responsibility, these actors effectively work to frame how China's duties and obligations are to be perceived. This, in turn, results in a triangulation effect where indigenous Chinese understandings of responsibility intersect with regional and international discourses to influence China's engagement with an evolving world society. -- Abstract provided by candidate.

We investigate the sensitivity of the branching ratio, lepton polarization and forward-backward asymmetry A_{FB} to the compactification parameter (1/R) We obtain that the branching ratio changed about 50% compared to the SM value, when (1/R=200 GeV) and zero position of the forward-backward asymmetry is shifted to the left compared to the SM result. Therefore measurement of the branching ratio of (Lambda_b -> Lambda l^+ l^-) decay and determination of zero position of A_{FB} are very useful in looking for new physics in the framework of the UED models.

description: Solar flares are explosive releases of magnetic energy. Hard X-ray (HXR) flare emission originates from both hot (millions of Kelvin) plasma and nonthermal accelerated particles, giving insight into flare energy release. The Nuclear Spectroscopic Telescope ARray (NuSTAR) utilizes direct focusing optics to attain much higher sensitivity in the HXR range than that of previous indirect imagers. This paper presents eleven NuSTAR microflares from two active regions (AR 12671 on 2017 August 21, and AR 12712 on 2018 May 29). The temporal, spatial, and energetic properties of each are discussed in context with previously published HXR brightenings. They are seen to display several 'large-flare' properties, such as impulsive time profiles and earlier peaktimes in higher energy HXRs. For two events where active region background could be removed, microflare emission did not display spatial complexity: differing NuSTAR energy ranges had equivalent emission centroids. Finally, spectral fitting showed a high energy excess over a single thermal model in all events. This excess was consistent with additional higher-temperature plasma volumes in 10/11 microflares, and consistent only with an accelerated particle distribution in the last. Previous NuSTAR studies focused on one or a few microflares at a time, making this the first to collectively examine a sizable number of events. Additionally, this paper introduces an observed variation in the NuSTAR gain unique to the extremely low-livetime (<1%) regime, and establishes a correction method to be used in future NuSTAR solar spectral analysis.

Family constellation and cognitive development in three-and five-year-old children from the Millennium Cohort Study
Creators: name: Hanna, Dana Joyce
Publisher: name: The Australian National University
Year: 2019

description: Using data from the British Millennium Cohort Study, this dissertation studies the effect of the family constellation on the cognitive development levels of children at the ages of three and five years. The first paper looks at the correlation between family size, birth order and the age gap between sibling births and cognitive ability test results at the ages of three and five years. For three-year-olds, family size and birth order are negatively correlated with vocabulary scores and school readiness scores. Larger age gaps between subsequent children have the potential to mitigate this impact. At the age of five years, family size is still negatively correlated with vocabulary and spatial reasoning test scores. While birth order is negatively correlated with vocabulary scores, it is positively correlated with spatial reasoning scores. Spacing between siblings still has an ameliorating effect for the younger sibling, yet is somewhat weaker than at the age of three. Interestingly, family constellation aspects have no statistical relationship to non-verbal reasoning (picture similarity) scores at age five. Paper two investigates the relationship between the family constellation and the progress of children's vocabulary ability between the ages of three and five years. The results give limited evidence that family size has a statistical, or sizeable, relationship with the progress of children's cognitive ability. Rather, children of higher birth order and those raised by single parents show, on average, smaller rates of progress between the ages of three and five. Single parenting has the greatest (negative) effect on those children with higher levels of initial ability. The third paper uses an instrumental variable approach to account for problems resulting from endogenously determined family size. Twins at last birth is used to instrument for family size. Results indicate that while there is a negative relationship between family size and children's cognitive outcomes, the relationship is weak. Rather, there is stronger evidence for birth order driving the differences in cognitive scores. Evidence pertaining to the effect of the spacing between a child and its older sibling suggests that greater spacing may be beneficial for the younger sibling.

description: Bus systems involve complex bus-bus and bus-passengers interactions. We study the problem of assigning buses to bus stops to minimise the average waiting time of passengers, W. An analytical theory for two specific cases of interactions is formulated: normal situation where all buses board passengers from every bus stop, versus novel express buses where disjoint subsets of non-interacting buses serve disjoint subsets of bus stops. Our formulation allows exact calculation of W for general loops in the two cases examined. Compared with regular buses, we present scenarios where express buses show improvement in W. Useful insights are obtained from our theory: 1) there is a minimum number of buses needed, 2) splitting a crowded bus stop into two less crowded ones always increases W for regular buses, 3) changing the destination of passengers and location of bus stops do not influence W. In the second part, we introduce a reinforcement-learning platform that overcomes limitations of our analytical method to search for better allocations of buses to bus stops that minimise W. Compared with the previous cases, any possible interaction between buses is allowed, unlocking novel emergent strategies. We apply this tool to a simple toy model and three empirically-motivated bus loops, based on data collected from the Nanyang Technological University shuttle bus system. In the simplified model, we observe an unexpected strategy emerging that could not be analysed with our mathematical formulation and displays chaotic behaviour. The possible configurations in the three empirically-motivated scenarios are approximately 10^11, 10^11 and 10^20, so a brute-force approach is impossible. Our algorithm reduces W by 12% to 32% compared with regular buses and 12% to 29% compared with express buses. This tool has practical applications because it works independently of the specific characteristics of a bus loop.

description: The behaviour of the pulsar spectrum at high radio frequencies can provide decisive information about the nature of the radio emission mechanism. We report recent observations of a selected sample of pulsars at lambda=9mm (32 GHz) with the 100-m Effelsberg radio telescope.Three pulsars, PSR B0144+59, PSR B0823+26, and PSR B2022+50, were detected for the first time at this frequency. We confirm the earlier flux density measurements for a sample of six pulsars, and we are able to place upper flux density limits for another 12 pulsars. We find that all pulsar spectra have a simple form that can be described using only three parameters, one of which is the lifetime of short nano-pulses in the emission region.The study of the transition region from coherent to incoherent emission needs further and more sensitive observations at even higher radio frequencies.

description: Adaptive estimation of linear functionals over a collection of parameter spaces is considered. A between-class modulus of continuity, a geometric quantity, is shown to be instrumental in characterizing the degree of adaptability over two parameter spaces in the same way that the usual modulus of continuity captures the minimax difficulty of estimation over a single parameter space. A general construction of optimally adaptive estimators based on an ordered modulus of continuity is given. The results are complemented by several illustrative examples.

description: On 2020 February 24, during their third observing run ("O3"), the Laser Interferometer Gravitational-wave Observatory and Virgo Collaboration (LVC) detected S200224ca: a candidate gravitational wave (GW) event produced by a binary black hole (BBH) merger. This event was one of the best-localized compact binary coalescences detected in O3 (with 50%/90% error regions of 13/72 deg$^2$), and so the Neil Gehrels Swift Observatory performed rapid near-UV/X-ray follow-up observations. Swift-XRT and UVOT covered approximately 79.2% and 62.4% (respectively) of the GW error region, making S200224ca the BBH event most thoroughly followed-up in near-UV (u-band) and X-ray to date. No likely EM counterparts to the GW event were found by the Swift BAT, XRT, or UVOT, nor by other observatories. Here we report on the results of our searches for an EM counterpart, both in the BAT data near the time of the merger, and in follow-up UVOT/XRT observations. We also discuss the upper limits we can place on EM radiation from S200224ca, and the implications these limits have on the physics of BBH mergers. Namely, we place a shallow upper limit on the dimensionless BH charge, $\hat{q} < 1.4 \times10^{-4}$, and an upper limit on the isotropic-equivalent energy of a blast wave $E < 4.1\times10^{51}$ erg (assuming typical GRB parameters).

Creators: name: Schmid, Stephan
Year: 2023

description: Inhaltlich befasst sich die vorliegende Masterarbeit mit dem Einsatz von digitalen Medien im Schulunterricht und deren Auswirkungen auf den Wissenszuwachs bei Schülerinnen und Schülern. Hierbei liegt der Fokus auf dem Einsatz von Apps im Mathematikunterricht, in welchem speziell die Lern-App „Studyly“ eingesetzt wird. Im Hinblick auf die Wirkung dieser Lern-App wird erforscht, ob sich der Wissenszuwachs bei Schülerinnen und Schülern durch digitale Medien vom Wissenszuwachs bei Lernenden durch traditionelle Unterrichtsmethoden in zwei verschiedenen mathematischen Themengebieten unterscheidet. Der theoretische Teil der Arbeit behandelt zunächst die Entwicklung von digitalen Medien in der Schule und gibt einen detaillierten Bericht über zwei aktuelle Reformen im österreichischen Bildungssystem wieder. Des Weiteren werden Vor- und Nachteile von Apps im Schulunterricht sowie speziell im Mathematikunterricht angeführt und diskutiert. Zuletzt werden Auswahlkriterien für Lern-Apps, ein entwickeltes Zertifizierungsprogramm und das Gütesiegel für Lern-Apps näher vorgestellt. Im empirischen Teil der Arbeit wird eine Vergleichsstudie mit insgesamt vier ersten Klassen (fünfte Schulstufe) einer AHS-Unterstufe im Bundesland Niederösterreich im Unterrichtsfach Mathematik durchgeführt. In dieser werden die Inhalte in zwei Klassen mit der Lern-App „Studyly“ und in den anderen beiden Klassen mit traditionellen Unterrichtsmethoden gelehrt. Nach Ablauf des Beobachtungszeitraums wird ein anonymer schriftlicher Test in allen vier Klassen durchgeführt, um den Wissenszuwachs der Schülerinnen und Schüler bei den mathematischen Themen zu erheben. Die Auswertung der Daten erfolgt mit dem Tabellenkalkulationsprogramm Microsoft Excel (Version 2305) und mit der Software „SPSS Statistics“ (Version 29). Um signifikante Unterschiede beim Wissenszuwachs der Schülerinnen und Schüler feststellen zu können, werden Kennzahlen der deskriptiven Statistik und der Inferenzstatistik herangezogen. Die Ergebnisse der empirischen Untersuchung zeigen, dass der Einsatz von digitaler Technologie, speziell durch Lern-Apps, zu keinem höheren Wissenszuwachs bei Lernenden im Vergleich zu traditionellen Unterrichtsmethoden im Mathematikunterricht führt.

description: The digital economy holds new opportunities for value creation but also threats for both companies and customers. Within this setting, the concept of Corporate Digital Responsibility (CDR) gains traction. Building on the well-established concept of Corporate Social Responsibility, CDR entails a set of principles through which it seeks to ensure an ethical and responsible development, deployment, and use of digital technologies. To date, the scholarly conceptualization of CDR is still in its infancy. This study pursues two main objectives: Firstly, it seeks to contribute to CDR theory by providing a more in-depth conceptualization with focus on privacy and data security. Secondly, this study provides first guidance for the evaluation of CDR activities on company-level, a benchmark corpus. As work-in-progress, the focus lies on identifying a starting point for the evaluation of CDR activities concentrating on privacy and data security, and hence research opportunities related to this assessment in future.

description: The recent suggestion that dramatic changes may occur in the lifetime of alpha and beta decay when the activity, in a pure metal host, is cooled to a few Kelvin, is examined in the light of published low temperature nuclear orientation (LTNO) experiments, with emphasis here on alpha decay. In LTNO observations are made of the anisotropy of radioactive emissions with respect to an axis of orientation. Correction of data for decay of metallic samples held at temperatures at and below 1 Kelvin for periods of days and longer has been a routine element of LTNO experiments for many years. No evidence for any change of half life on cooling, with an upper level of less than 1%, has been found, in striking contrast to the predicted changes, for alpha decay, of several orders of magnitude. The proposal that such dramatic changes might alleviate problems of disposal of long-lived radioactive waste is shown to be unrealistic.

description: Zur schnellen Erkennung von gefährlichen Stürzen in betreuten Wohnsituationen können klassische Kameras kombiniert mit künstlichen neuronalen Netzen (Artificial Neural Networks) verwendet werden. Solche Lösungen haben allerdings eine hohe elektrische Leistungsaufnahme und erfordern daher eine dauerhafte Stromversorgung. Dies macht die Integration in bestehende Räume aufwendig. Im Rahmen des Projekts EmbeddedNeuroVision wird daher eine extrem energieeffiziente Lösung basierend auf neuromorphen Kameras und Spiking Neural Networks erforscht, die die elektrische Leistungsaufnahme um mehrere Größenordnungen senken kann. Die energieeffiziente Verarbeitung schafft neue Möglichkeiten für batteriebetriebene Visionssysteme, die nicht nur im betreuten Wohnen, sondern auch in industriellen und Smart-City-Anwendungen flexibler eingesetzt werden können.

description: We utilize existing inclusive data on K^+ meson momentum spectra of the reaction pp -> K^+X at T_p = 2.3 - 2.85 GeV to deduce total cross sections for pp -> K^+Σ^+n. The method used to extract those cross sections is explained and discussed in detail. Our result for T_p = 2.85 GeV is consistent with the data point from a direct measurement at the same beam energy. The cross section obtained for T_p = 2.3 GeV is with 13.7\pm2.3 μb considerably smaller than the value found in a recent experiment by the COSY-11 Collaboration at a somewhat lower beam energy, indicating that the pp -> K^+Σ^+n reaction cross section could exhibit a rather unusual energy dependence.

Isomerisation Puzzles viewed with High Resolution Photoelectron Imaging

description: Anion photoelectron spectroscopy has proven to be a versatile technique for studying transient neutral species, with very fast dynamics, as it obtains information from both the parent negative ion and the reactant neutral molecule. This technique is particularly useful for the study of chemical reactions where the transition state possess a stable anion. The development of velocity map imaging has greatly improved the spectral resolution and collector efficiency that may be achieved in charged particle detection, to allow for unprecedented detail in the recorded molecular spectra. In this work, a High Resolution Photoelectron Imaging (HR-PEI) spectrometer is used to investigate the nature of isomerisation. A benchmark study of NO2- photodetachment reveals rotationally resolved structure, with a rapid change in the electron anisotropy behaviour near threshold used to decode the character of the highest occupied molecular orbital (HOMO). Measurements close to photodetachment threshold display additional high kinetic energy electron structure that cannot be associated with the ONO C2v isomer. These additional fast electrons have the spectral signature of the Cs peroxy isomer NOO, with spectral analysis providing the first experimental evidence to confirm that the NOO isomer exists as a bound molecule. High resolution studies of similar atmospherically relevant molecules NO, O, and O2 have been used for calibration, and determine new detail about these species. A second section of this work tackles the long-standing problem of the vinylidene - acetylene isomerisation. The 1,2-hydrogen migration is a common mechanism in more complex organic reactions, making this an attractive area of research as a prototypical study. However, the dynamics of the vinylidene isomer are still poorly understood, in part due to conflicting experimental results. Photoelectron spectra of the vinylidene anion, presented in this work, reveal the presence of forbidden non-totally symmetric vibrational modes associated with a discrete jump in the anisotropy parameter. This is a consequence of Herzberg-Teller coupling between electronic states, and is essential for isomerisation to occur. Spectral signatures possessing an admixture of both vinylidene and highly excited acetylene local-bender character are discovered, providing a map of the doorway vibrational states through which the isomerization proceeds. Similar molecules dicarbon and ethynyl are also studied, where the complex coupling mechanisms between the ground and first excited state of ethynyl provide more insight into the Herzberg-Teller interaction. The nature of dicarbon bonding is examined, with the anisotropy of C2- photodetachment determining the presence of a double bond, despite recent theoretical suggestions that a quadruple bond may be present.

Optical activity in the Drude helix model

description: An old classical one-particle helix model for optical activity, first proposed by Drude, is reconsidered here. The quantum Drude model is very instructive because the optical activity can be calculated analytically without further approximations apart from the Rosenfeld long wavelength approximation. While it was generally believed that this model, when treated correctly, is optically inactive, we show that it leads to optical activity when the motion of the particle is quantum mechanically treated. We also find that optical activity arises even in the classical regime at non-zero energy, while for zero energy the model is inactive, in accordance with previous results. The model is compared with other one-electron models and it is shown that its predicted optical activity is qualitatively different from those of other one-electron systems. The vanishing of optical activity in the classical zero-energy limit for the Drude model is due to the localization of the particle at the equilibrium position, whereas in the analogous model of a particle moving freely on a helix without a definite equilibrium position, optical activity does not vanish but the spectrum is rescaled. The model under study leads to interesting predictions about the optical properties of e. g. helicene derivatives.

description: Research in photonic computing has flourished due to the proliferation of optoelectronic components on photonic integration platforms. Photonic integrated circuits have enabled ultrafast artificial neural networks, providing a framework for a new class of information processing machines. Algorithms running on such hardware have the potential to address the growing demand for machine learning and artificial intelligence, in areas such as medical diagnosis, telecommunications, and high-performance and scientific computing. In parallel, the development of neuromorphic electronics has highlighted challenges in that domain, in particular, related to processor latency. Neuromorphic photonics offers sub-nanosecond latencies, providing a complementary opportunity to extend the domain of artificial intelligence. Here, we review recent advances in integrated photonic neuromorphic systems, discuss current and future challenges, and outline the advances in science and technology needed to meet those challenges.

description: We consider n one-dimensional Brownian motions, such that n/2 Brownian motions start at time t=0 in the starting point a and end at time t=1 in the endpoint b and the other n/2 Brownian motions start at time t=0 at the point -a and end at time t=1 in the point -b, conditioned that the n Brownian paths do not intersect in the whole time interval (0,1). The correlation functions of the positions of the non-intersecting Brownian motions have a determinantal form with a kernel that is expressed in terms of multiple Hermite polynomials of mixed type. We analyze this kernel in the large n limit for the case ab<1/2. We find that the limiting mean density of the positions of the Brownian motions is supported on one or two intervals and that the correlation kernel has the usual scaling limits from random matrix theory, namely the sine kernel in the bulk and the Airy kernel near the edges.
