description: ATG9A and ATG2A are essential core members of the autophagy machinery. ATG9A is a lipid scramblase that allows equilibration of lipids across a membrane bilayer, whereas ATG2A facilitates lipid flow between tethered membranes. Although both have been functionally linked during the formation of autophagosomes, the molecular details and consequences of their interaction remain unclear. By combining data from peptide arrays, crosslinking, and hydrogen-deuterium exchange mass spectrometry together with cryoelectron microscopy, we propose a molecular model of the ATG9A-2A complex. Using this integrative structure modeling approach, we identify several interfaces mediating ATG9A-2A interaction that would allow a direct transfer of lipids from ATG2A into the lipid-binding perpendicular branch of ATG9A. Mutational analyses combined with functional activity assays demonstrate their importance for autophagy, thereby shedding light on this protein complex at the heart of autophagy.

description: In this work, we study magnetization dynamics in superconductor-ferromagnet-superconductor thin-film structures. Results of the broad-band ferromagnetic resonance spectroscopy are reported for a large set of samples with varied thickness of both superconducting and ferromagnetic layers in a wide frequency, field, and temperature ranges. Experimentally the one-dimensional anisotropic action of superconducting torque on magnetization dynamics is established; its dependence on thickness of layers is revealed. It is demonstrated that experimental findings support the recently-proposed mechanism of the superconducting torque formation via the interplay between the superconducting kinetic inductance and magnetization precession at superconductor-ferromagnet interfaces.

description: We propose a near-optimum receiver for the discrimination of binary phase-shift-keyed coherent states employing photon-number-resolving detectors. The receiver exploits a discrimination strategy based on both the so-called homodyne-like and the direct detection, thus resulting in a hybrid scheme. We analyse the performance and the robustness of the proposed scheme under realistic conditions, namely, in the presence of inefficient detection and dark counts. We show that the present hybrid setup is near-optimum and beats both the standard-quantum-limit and the performance of the Kennedy receiver.

description: Suppose $F=\mathbb{Q}(\sqrt{-p_1\dotsm p_t})$ is an imaginary quadratic number field with distinct primes $p_1,\dots,p_{t}$, where $p_i\equiv 1\pmod{4}$ ($i=1,\dots,t-1$) and $p_t\equiv 3\pmod{4}$. We express the possible values of the 8-rank $r_8$ of the class group of $F$ in terms of a quadratic form $Q$ over $\mathbb{F}_2$ which is defined by quartic symbols. In particular, we show that $r_8$ is bounded by the isotropy index of $Q$.

description: The harmonic sum of the integers which are missing $p$ given digits in a base $b$ is expressed as $b\log(b)/p$ plus corrections indexed by the excluded digits and expressed as integrals involving the digamma function and a suitable measure. A number of consequences are derived, such as explicit bounds, monotony, series representations and asymptotic expansions involving the zeta values at integers, and suitable moments of the measure. In the classic Kempner case of $b=10$ and $9$ as the only excluded digit, the series representation turns out to be exactly identical with a result obtained by Fischer already in 1993. Extending this work is indeed the goal of the present contribution.

description: Upper limb movement classification, which maps input signals to the target activities, is a key building block in the control of rehabilitative robotics. Classifiers are trained for the rehabilitative system to comprehend the desires of the patient whose upper limbs do not function properly. Electromyography (EMG) signals and Electroencephalography (EEG) signals are used widely for upper limb movement classification. By analysing the classification results of the real-time EEG and EMG signals, the system can understand the intention of the user and predict the events that one would like to carry out. Accordingly, it will provide external help to the user. However, the noise in the real-time EEG and EMG data collection process contaminates the effectiveness of the data, which undermines classification performance. Moreover, not all patients process strong EMG signals due to muscle damage and neuromuscular disorder. To address these issues, this paper explores different feature extraction techniques and machine learning and deep learning models for EEG and EMG signals classification and proposes a novel decision-level multisensor fusion technique to integrate EEG signals with EMG signals. This system retrieves effective information from both sources to understand and predict the desire of the user, and thus aid. By testing out the proposed technique on a publicly available WAY-EEG-GAL dataset, which contains EEG and EMG signals that were recorded simultaneously, we manage to conclude the feasibility and effectiveness of the novel system.

description: Recently developed Josephson junction array transmission lines implement strong-coupling circuit electrodynamics compatible with a range of superconducting quantum devices. They provide both the high impedance which allows for strong quantum fluctuations, and photon modes with which to probe a quantum device, such as a small Josephson junction. In this high-impedance environment, current through the junction is accompanied by charge Bloch oscillations analogous to those in crystalline systems. However, the interplay between Bloch oscillations and environmental photon resonances remains largely unexplored. Here we describe the Bloch oscillations in a transmon-type qubit attached to high-impedance transmission lines with discrete photon spectra. Transmons are characterized by well-separated charge bands, favoring Bloch oscillations over Landau-Zener tunneling. We find resonances in the voltage--current relation and the spectrum of photons emitted by the Bloch oscillations. The transmon also scatters photons inelastically; we find the cross-section for a novel anti-Stokes-like process whereby photons gain a Bloch oscillation quantum. Our results outline how Bloch oscillations leave fingerprints for experiments across the DC, MHz, and GHz ranges.

description: Swelling of uranium dioxide with ingrowth of defects by irradiation is not fully understood. Experimental and theoretical groups have attempted to explain this phenomenon with various complex theories. In this study, experimental lattice expansion and super saturation of the lattice were well reproduced by molecular dynamics simulation method. From the resemblance with the experimental data, here it is manifested that only oxygen frenkel pairs were created in the fission induced lattice while alpha particle radiation causes both oxygen and considerable amount of uranium defects. Moreover, in this work, defects are divided into two sub-groups as obstruction and distortion and it is shown that obstruction type frenkel pairs merely responsible for the lattice swelling for both fission and alpha particle radiation. Evidently relative lattice expansion varies linearly with the obstruction type of survived uranium defects. Additionally, at high concentrations, some of the obstruction type uranium frenkel pairs forming double or triple structures with oxygens in their octahedral cages which increase the slope of the linear dependence.

description: Self-admitted technical debt (SATD) refers to a form of technical debt in which developers explicitly acknowledge and document the existence of technical shortcuts, workarounds, or temporary solutions within the codebase. Over recent years, researchers have manually labeled datasets derived from various software development artifacts: source code comments, messages from the issue tracker and pull request sections, and commit messages. These datasets are designed for training, evaluation, performance validation, and improvement of machine learning and deep learning models to accurately identify SATD instances. However, class imbalance poses a serious challenge across all the existing datasets, particularly when researchers are interested in categorizing the specific types of SATD. In order to address the scarcity of labeled data for SATD \textit{identification} (i.e., whether an instance is SATD or not) and \textit{categorization} (i.e., which type of SATD is being classified) in existing datasets, we share the \textit{SATDAUG} dataset, an augmented version of existing SATD datasets, including source code comments, issue tracker, pull requests, and commit messages. These augmented datasets have been balanced in relation to the available artifacts and provide a much richer source of labeled data for training machine learning or deep learning models.

description: Although Deep Reinforcement Learning (DRL) has been popular in many disciplines including robotics, state-of-the-art DRL algorithms still struggle to learn long-horizon, multi-step and sparse reward tasks, such as stacking several blocks given only a task-completion reward signal. To improve learning efficiency for such tasks, this paper proposes a DRL exploration technique, termed A^2, which integrates two components inspired by human experiences: Abstract demonstrations and Adaptive exploration. A^2 starts by decomposing a complex task into subtasks, and then provides the correct orders of subtasks to learn. During training, the agent explores the environment adaptively, acting more deterministically for well-mastered subtasks and more stochastically for ill-learnt subtasks. Ablation and comparative experiments are conducted on several grid-world tasks and three robotic manipulation tasks. We demonstrate that A^2 can aid popular DRL algorithms (DQN, DDPG, and SAC) to learn more efficiently and stably in these environments.

description: The observation of the B-mode in the cosmic microwave background radiation combined with the so-called Lyth bound suggests the trans-Planckian variation of the inflaton field during inflation. Such a large variation generates concerns over inflation models in terms of the effective field theory below the Planck scale. If the inflaton resides in a Riemann surface and the inflaton potential is a multivalued function of the inflaton field when it is viewed as a function on a complex plane, the Lyth bound can be satisfied while keeping field values in the effective field theory within the Planck scale. We show that a multivalued inflaton potential can be realized starting from a single-valued Lagrangian of the effective field theory below the Planck scale.

description: $n$-cycle permutations with small $n$ have the advantage that their compositional inverses are efficient in terms of implementation. They can be also used in constructing Bent functions and designing codes. Since the AGW Criterion was proposed, the permuting property of several forms of polynomials has been studied. In this paper, characterizations of several types of $n$-cycle permutations are investigated. Three criteria for $ n $-cycle permutations of the form $xh(λ(x))$, $ h(ψ(x)) φ(x)+g(ψ(x)) $ and $g\left( x^{q^i} -x +δ\right) +bx $ with general $n$ are provided. We demonstrate these criteria by providing explicit constructions. For the form of $x^rh(x^s)$, several new explicit triple-cycle permutations are also provided. Finally, we also consider triple-cycle permutations of the form $x^t + c\rm Tr_{q^m/q}(x^s)$ and provide one explicit construction. Many of our constructions are both new in the $n$-cycle property and the permutation property.

description: Hot Jupiters are expected to form far from their host star and move toward close-in, circular orbits via a smooth, monotonic decay due to mild and constant tidal dissipation. Yet, three systems have recently been found exhibiting planet-induced stellar pulsations suggesting unexpectedly strong tidal interactions. Here we combine stellar evolution and tide models to show that dynamical tides raised by eccentric gas giants can give rise to chains of resonance locks with multiple modes, enriching the dynamics seen in single-mode resonance locking of circularized systems. These series of resonance locks yield orders-of-magnitude larger changes in eccentricity and harmonic pulsations relative to those expected from a single episode of resonance locking or nonresonant tidal interactions. Resonances become more frequent as a star evolves off the main sequence providing an alternative explanation to the origin of some stellar pulsators and yielding the concept of "dormant migrating giants". Evolution trajectories are characterized by competing episodes of inward/outward migration and spin-up/-down of the star which are sensitive to the system parameters, revealing a new challenge in modeling migration paths and in contextualizing the observed populations of giant exoplanets and stellar binaries. This sensitivity however offers a new window to constrain the stellar properties of planetary hosts via tidal asteroseismology.

description: Unterricht ist bekanntermaßen ein komplexes Geschehen, in dem sich Mathematiklehrkräfte zeitgleich mit vielfältigen Situationen und Ereignissen konfrontiert sehen. Um auf die heterogenen Lernvoraussetzungen von Lernenden situationsangemessen eingehen zu können, sind Lehrkräfte gefordert, ganz unterschiedliche Kriterien zu berücksichtigen, um ihr Handeln entsprechend auf die Bedarfe der Lernenden abstimmen zu können. Ein solcher simultaner Umgang mit mehreren Kriterien kann, wie in Kuntze et al. (2021) detaillierter ausgeführt wurde, mithilfe des Begriffs des Multi-Criterion Noticing näher beschrieben werden. Im mathematikdidaktischen Diskurs existieren mittlerweile diverse Arbeiten zu verschiedenen Aspekten des Noticings in verschiedenen Themenbereichen, etwa bezogen auf den Umgang mit Darstellungen im Mathematikunterricht (z.B. Dreher & Kuntze, 2015; Friesen & Kuntze, 2016). Simultanes Noticing in Bezug auf mehrere Kriterien, speziell im Hinblick auf den Umgang mit heterogenen Lernvoraussetzungen im Mathematikunterricht der Grundschule, fand im Diskurs allerdings bislang erst wenig Berücksichtigung, sodass hierzu spezifische Forschung notwendig ist, um Lehramtsstudierende bereits im Studium bestmöglich darauf vorbereiten zu können, theoriebasiertes Kriterienwissen mit Wahrnehmungen zu konkreten Unterrichtssituationen verknüpfen zu können. In diesem Beitrag geben wir Einblicke in die vignettenbasierte Untersuchung von Multi-Criterion Noticing bei Lehramtsstudierenden.
“Comply or Goodbye”: A Comparative Case Study Exploring How Two Different Communities in Chicago Mobilized Against General Iron
Creators: name: Sandino, Laura
Publisher: name: University of Chicago
Year: 2023

description: This paper conducts a sociological case study into the movements created in response to General Iron’s relocation from the affluent, predominantly white neighborhood of Lincoln Park in Chicago’s North Side to the low-income Black and Latinx neighborhood of the Southeast Side of Chicago. Through in-depth interviews conducted with residents and organizers from both of these communities, I find that while Lincoln Park used a NIMBY (Not-In-My-Back-Yard) framing to push General Iron out of their area, the Southeast Side created the Stop General Iron movement and used environmental justice (EJ) framing to successfully prevent the company from relocating into their community. While both of these movements succeeded in their goals, I find that Stop General Iron had to resort to more radical mobilization strategies, such as protests and a 30-day hunger strike, than Lincoln Parkers. I argue that this is due to the City of Chicago’s discriminatory treatment of the South Side of Chicago, and because of historically racist zoning laws that have reproduced these environmental injustices in the Southeast Side and kept the area as an industrial dumping ground.

description: The phase and thermal driven transport properties of the T-shaped uncorrelated double quantum dot Josephson junction are analyzed by using Keldysh non-equilibrium Green's function equation of motion technique. In this setup, we have shown that the side-attached quantum dot provides an additional route for electron transmission which is affecting the transport properties by adjusting the interdot hopping between the main dot and the side dot. We began with investigating the impact of interdot hopping on Andreev bound states and Josephson supercurrent. When a small thermal bias is applied across the superconducting leads, the system exhibits a finite thermal response which is primarily due to the, thermally induced, quasi-particle current. The behavior of the Josephson supercurrent and the quasi-particle current flowing through the quantum dots is examined for various interdot hopping and thermal biasing. Finally, the system is considered in an open circuit configuration where the thermally driven quasi-particle current is compensated by the phase-driven Josephson supercurrent and the thermophase effect is observed. The effect of interdot hopping and the position of quantum dot energy level on the thermophase Seebeck coefficient is investigated

description: Classification of an object behind a random and unknown scattering medium sets a challenging task for computational imaging and machine vision fields. Recent deep learning-based approaches demonstrated the classification of objects using diffuser-distorted patterns collected by an image sensor. These methods demand relatively large-scale computing using deep neural networks running on digital computers. Here, we present an all-optical processor to directly classify unknown objects through unknown, random phase diffusers using broadband illumination detected with a single pixel. A set of transmissive diffractive layers, optimized using deep learning, forms a physical network that all-optically maps the spatial information of an input object behind a random diffuser into the power spectrum of the output light detected through a single pixel at the output plane of the diffractive network. We numerically demonstrated the accuracy of this framework using broadband radiation to classify unknown handwritten digits through random new diffusers, never used during the training phase, and achieved a blind testing accuracy of 88.53%. This single-pixel all-optical object classification system through random diffusers is based on passive diffractive layers that process broadband input light and can operate at any part of the electromagnetic spectrum by simply scaling the diffractive features proportional to the wavelength range of interest. These results have various potential applications in, e.g., biomedical imaging, security, robotics, and autonomous driving.

description: In this paper, we investigate the anomalous dispersive relations, inverse scattering transform with a Riemann-Hilbert (RH) problem, and fractional multi-solitons of the integrable combined fractional higher-order mKdV (fhmKdV) hierarchy, including the fractional mKdV (fmKdV), fractional fifth-order mKdV (f5mKdV), fractional combined third-fifth-order mKdV (f35mKdV) equations, etc., which can be featured via completeness of squared scalar eigenfunctions of the ZS spectral problem. We construct a matrix RH problem to present three types of fractional N-solitons illustrating anomalous dispersions of the combined fhmKdV hierarchy for the reflectionless case. As some examples, we analyze the wave velocity of the fractional one-soliton such that we find that the fhmKdV equation predicts a power law relationship between the wave velocity and amplitude, and demonstrates the anomalous dispersion. Furthermore, we illustrate other interesting anomalous dispersive wave phenomena containing the elastic interactions of fractional bright and dark solitons, W-shaped soliton and dark soliton, as well as breather and dark soliton. These obtained fractional multi-solitons will be useful to understand the related nonlinear super-dispersive wave propagations in fractional nonlinear media.

description: Η παρούσα μελέτη εστιάζει στη μέτρηση δεικτών απόδοσης στους Σταθμούς Αυτοκινήτων ενός λιμένα. Παρουσιάζεται ένας κατάλογος δεικτών που προέκυψαν από μια σειρά ερευνών και μεθοδολογιών. Στη συνέχεια, γίνεται προσπάθεια αξιοποίησης ορισμένων από αυτούς τους δείκτες στον κλάδο του τροχοφόρου φορτίου και συγκεκριμένα στην διακίνηση οχημάτων του Τερματικού Σταθμού οχημάτων του λιμένα Πειραιά για την περίοδο 2018-2021, αναφέρονται ενδεικτικά και τα έτη 2011- 2017. Τα αποτελέσματα της συνολικής διακίνησης οχημάτων διαφοροποιούνται αισθητά κατά την περίοδο αυτή καθώς υπάρχει μια σταθερή ανοδική πορεία κατά τα έτη 2018 και 2019 αλλά μειώνεται αισθητά το έτος 2020 λόγω της πανδαιμίας COVID- 19 η οποία και έπληξε τις συναλλαγές παγκοσμίως. Κατά το έτος 2021 παρουσιάζεται αισθητή αύξηση της διακίνησης τόσο εγχώριων όσο και μεταφορτώσεων (δια θαλάσσης φορτίων) για άλλους προορισμούς μέχρι και σήμερα. Η παρούσα εργασία πραγματεύεται στη μέτρηση της απόδοσης των Τερματικών Σταθμών Αυτοκινήτων Λιμένα. Αρχικά, επιχειρείται μία εισαγωγή στις έννοιες λιμάνι και Τερματικός Σταθμός λιμένα, γίνεται αναφορά στη δομή και στη διάρθρωση του λιμενικού κλάδου, προκειμένου να γίνει διάκριση στις γενιές των λιμένων και να παρουσιαστεί το θεσμικό πλαίσιο που τους χαρακτηρίζει. Κατόπιν, γίνεται αναφορά στην Ναυτιλία και στον ρόλο των λιμένων στο διεθνές εμπόριο και στην παγκόσμια οικονομία όσων αφορά τους παράγοντες που επηρεάζουν την ζήτηση των θαλάσσιων αποστολών. Παρουσιάζονται αναλυτικά οι Τερματικοί Σταθμοί Λιμένα. Περαιτέρω γίνεται αναφορά στα πλοία Ro-Ro. Πραγματοποιείται μια παρουσίαση στα συστήματα μέτρησης απόδοσης θαλάσσιων λιμένων αλλά και στην ανάγκη απόδοσης μετρήσεων στους Τερματικούς Σταθμούς λιμένων. Κατόπιν επιχειρείται μια ουσιαστική γνωριμία με το Λιμάνι του Πειραιά (ΟΛΠ ΑΕ) και εφαρμόζεται μεθοδολογία μελέτης στην περίπτωση του Τερματικού Σταθμού Αυτοκινήτων για τους τρόπους μέτρησης της απόδοσης του, χρηματοοικονομικούς αλλά και λειτουργικούς. Πραγματοποιείται μια Balancescore Card του Σταθμού Αυτοκινήτων και αναλύονται τα αποτελέσματά της. Τέλος γίνεται μια αναφορά στους Τερματικούς Σταθμούς Αυτοκινήτων γύρω από την Μεσόγειο και τη Μαύρη Θάλασσα και στους δέκα κορυφαίους Τερματικούς Σταθμούς Διακίνησης οχημάτων της Ευρώπης για τα έτη 2018 -2019. Η εργασία καταλήγει σε συμπεράσματα και σε μελλοντικά σχέδια του Σταθμού Αυτοκινήτων για την περαιτέρω εξέλιξη του.
Proposal for demonstrating the Hong-Ou-Mandel effect with matter waves

description: The Hong-Ou-Mandel (HOM) effect is a striking demonstration of destructive quantum interference between pairs of indistinguishable bosons, realised so far only with massless photons. Here we propose an experiment which can realise this effect in the matter-wave regime using pair-correlated atoms produced via a collision of two Bose-Einstein condensates and subjected to two laser induced Bragg pulses. We formulate a novel measurement protocol appropriate for the multimode matter-wave field, which---unlike the typical two-mode optical case---bypasses the need for repeated measurements under different displacement settings of the beam-splitter, thus dramatically reducing the number of experimental runs required to map out the interference visibility. The protocol can be utilised in related matter-wave schemes; here we focus on condensate collisions and by simulating the entire experiment we predict a HOM-dip visibility of ~69%. By being larger than 50%, such a visibility highlights strong quantum correlations between the atoms and paves the way for a possible demonstration of a Bell inequality violation with massive particles in a related Rarity-Tapster setup.

description: Spectral functions of non-Hermitian Hamiltonians can reveal the existence of topologically non-trivial line gaps and the associated topological edge modes. However, the computation of spectral functions in a non-Hermitian many-body system remains an open challenge. Here, we put forward a numerical approach to compute spectral functions of a non-Hermitian many-body Hamiltonian based on the kernel polynomial method and the matrix-product state formalism. We show that the local spectral functions computed with our algorithm reveal topological spin excitations in a non-Hermitian spin model, faithfully reflecting the non-trivial line gap topology in a many-body model. We further show that the algorithm works in the presence of the non-Hermitian skin effect. Our method offers an efficient way to compute local spectral functions in non-Hermitian many-body systems with tensor-networks, allowing to characterize line gap topology in non-Hermitian quantum many-body models.

description: eBay's experimentation platform runs hundreds of A/B tests on any given day. The platform integrates with the tracking infrastructure and customer experience servers, provides the sampling service for experiments, and has the responsibility to monitor the progress of each A/B test. There are many challenges especially when it is required to ensure experiment quality at the large scale. We discuss two automated test quality monitoring processes and methodologies, namely randomization validation using population stability index (PSI) and sample ratio mismatch (a.k.a. sample delta) detection using sequential analysis. The automated processes assist the experimentation platform to run high quality and trustworthy tests not only effectively on a large scale, but also efficiently by minimizing false positive monitoring alarms to experimenters.

description: In this paper we continue to study equivariant pencil liftings and differential operators on the algebra of densities. We emphasize the role that the geometry of the extended manifold plays. Firstly we consider basic examples. We give a projective line of diff($M$)-equivariant pencil liftings for first order operators, and the canonical second order self-adjoint lifting. Secondly we study pencil liftings equivariant with respect to volume preserving transformations. This helps to understand the role of self-adjointness for the canonical pencils. Then we introduce the Duval-Lecomte-Ovsienko (DLO)-pencil lifting which is derived from the full symbol calculus of projective quantisation. We use the DLO-pencil lifting to describe all regular proj-equivariant pencil liftings. In particular the comparison of these pencils with the canonical pencil for second order operators leads to objects related to the Schwarzian. Within this paper the question of whether the pencil lifting factors through a full symbol map naturally arises.

description: This thesis examines the problem of AI consciousness: how do we tell that an AI is conscious? At its core, this question is just an extension of a long-standing philosophical problem called the problem of other minds (POM): how do I know that other people have minds? I will be taking three solutions that have been proposed to the POM – the argument from analogy (AA), the argument from best explanation (ABE), and the argument from criteria (AfC) – and apply them to the problem of AI consciousness.

description: Die Nutzung öffentlich zugänglicher Erklärvideos (z. B. über YouTube oder Sofatutor) spielt als Lernangebot eine bedeutende Rolle für schulische Lehr- Lern-Prozesse (Wolf & Kulgemeyer, 2021). Videos zum Schulfach Mathematik nehmen dabei den Spitzenplatz hinsichtlich der Nutzungshäufigkeit ein und werden von mehr als einem Fünftel der Schüler*innen mindestens einmal pro Woche genutzt (Wolf & Kulgemeyer, 2021). Obwohl fachlich anspruchsvolle Konzepte durch das Schauen von Erklärvideos verstanden werden können (Korntreff & Prediger, 2021), überwiegen Studien, die auf negative Effekte bzgl. des Verstehens mit Erklärvideos hindeuten: Erklärvideos enthalten teils fehlerhaft oder didaktisch defizitäre Erklärungen, die Fehlvorstellungen vertiefen und eine Verstehensillusion entstehen lassen können (Kulgemeyer & Wittwer, 2022). In solchen Fällen können weitere Erklärungen eigener Lehrkräfte als redundant erlebt oder sogar abgelehnt werden (Wolf & Kulgemeyer, 2021). Um sich dem Themenfeld der Verstehensillusion anzunähern, untersuchen wir zunächst Merkmale von Erklärvideos, die dazu führen, dass die präsentierten Inhalte von Lernenden akzeptiert werden.
