description: The radial extent of millimetre dust in protoplanetary discs is often far smaller than that of their gas, mostly due to processes such as dust growth and radial drift. However, it has been suggested that current millimetre continuum observations of discs do not trace their full extent due to limited sensitivity. In this Letter, we present deep (19 $μ$Jy beam$^{-1}$) moderate resolution (0.37") ALMA observations at 1 mm of the nearest protoplanetary disc, TW Hya. Using the visibility analysis tool `frank', we reveal a structured millimetre intensity distribution out to 100 au, well beyond previous estimates of 60-70 au. Our analysis suggests the presence of a new millimetre continuum gap at 82 au, coincident with similar features seen in optical/near-infrared scattered light and millimetre molecular line observations. Examination of the fit residuals confirms the presence of the previously reported au-scale continuum excess at 52 au (P.A. = 242.5 degrees). Our results demonstrate the utility of combining deep, moderate resolution observations with super-resolution analysis techniques to probe the faintest regions of protoplanetary discs.

description: Quantum computers potentially have an exponential advantage over classical computers for the quantum simulation of many-fermion quantum systems. Nonetheless, fermions are more expensive to simulate than bosons due to the fermionic encoding -- a mapping by which the qubits are encoded with fermion statistics. Here we generalize the contracted quantum eigensolver (CQE) to avoid fermionic encoding of the wave function. In contrast to the variational quantum eigensolver, the CQE solves for a many-fermion stationary state by minimizing the contraction (projection) of the Schrödinger equation onto two fermions. We avoid fermionic encoding of the wave function by contracting the Schrödinger equation onto an unencoded pair of particles. Solution of the resulting contracted equation by a series of unencoded two-body exponential transformations generates an unencoded wave function from which the energy and two-fermion reduced density matrix (2-RDM) can be computed. We apply the unencoded and the encoded CQE algorithms to the hydrogen fluoride molecule, the dissociation of oxygen O$_{2}$, and a series of hydrogen chains. Both algorithms show comparable convergence towards the exact ground-state energies and 2-RDMs, but the unencoded algorithm has computational advantages in terms of state preparation and tomography.
Escalade Sports semi-automated fulfillment line
Creators: name: Wright, Andrew
name: Lasme, Guy
Publisher: name: Unknown
Year: 2014

description: The Escalade Sports Distribution Warehouse fills orders to be shipped to retail outlets.
The products shipped range from tennis table accessories to basketball boards. Current state
operation of the processing lines requires the use of manual labor. With product demand
increasing, it brings an increase in shipping charge backs and a shortage of labor during peak
shopping seasons. This requires management to rethink their order processing methods.
By using a base hourly rate with a four operator team, it was found that the total labor
cost for the year was significant. The proposed semi-automated fulfillment line will process 3
times faster than cun-ent cycle times. Given the same hourly rate, it was calculated that the new
total labor cost for the year will be reduced by 50%. The proposed fulfillment line has an
automated visual inspection system that will verify the right products are being process and
correct label is placed on the proper location on the carton. The proposed fulfillment line will
justify itself with a return on investment of less than 2 years.

On the Impossibility of First-Order Phase Transitions in Systems Modeled by the Full Euler Equations

Subjects: subject: 510.72

description: Liquid–vapor flows exhibiting phase transition, including phase creation in single-phase flows, are of high interest in mathematics, as well as in the engineering sciences. In two preceding articles the authors showed on the one hand the capability of the isothermal Euler equations to describe such phenomena (Hantke and Thein, arXiv, 2017, arXiv:1703.09431). On the other hand they proved the nonexistence of certain phase creation phenomena in flows governed by the full system of Euler equations, see Hantke and Thein, Quart. Appl. Math. 2015, 73, 575–591. In this note, the authors close the gap for two-phase flows by showing that the two-phase flows considered are not possible when the flow is governed by the full Euler equations, together with the regular Rankine-Hugoniot conditions. The arguments rely on the fact that for (regular) fluids, the differences of the entropy and the enthalpy between the liquid and the vapor phase of a single substance have a strict sign below the critical point.

description: High spatial resolution CO observations of mid-inclination (30-75°) protoplanetary disks offer an opportunity to study the vertical distribution of CO emission and temperature. The asymmetry of line emission relative to the disk major axis allows for a direct mapping of the emission height above the midplane, and for optically-thick, spatially-resolved emission in LTE, the intensity is a measure of the local gas temperature. Our analysis of ALMA archival data yields CO emission surfaces, dynamically-constrained stellar host masses, and disk atmosphere gas temperatures for the disks around: HD 142666, MY Lup, V4046 Sgr, HD 100546, GW Lup, WaOph 6, DoAr 25, Sz 91, CI Tau, and DM Tau. These sources span a wide range in stellar masses (0.50-2.10 M$_{\odot}$), ages (${\sim}$0.3-23 Myr), and CO gas radial emission extents (${\approx}$200-1000 au). This sample nearly triples the number of disks with mapped emission surfaces and confirms the wide diversity in line emitting heights ($z/r\approx0.1$ to ${\gtrsim}0.5$) hinted at in previous studies. We compute radial and vertical CO gas temperature distributions for each disk. A few disks show local temperature dips or enhancements, some of which correspond to dust substructures or the proposed locations of embedded planets. Several emission surfaces also show vertical substructures, which all align with rings and gaps in the millimeter dust. Combining our sample with literature sources, we find that CO line emitting heights weakly decline with stellar mass and gas temperature, which, despite large scatter, is consistent with simple scaling relations. We also observe a correlation between CO emission height and disk size, which is due to the flared structure of disks. Overall, CO emission surfaces trace ${\approx}2$-$5\times$ gas pressure scale heights (H$_{\rm{g}}$) and could potentially be calibrated as empirical tracers of H$_{\rm{g}}$.

Conditional PISCES method for the NOνA 3-flavor oscillation analysis
Creators: name: Miriama Rajaoalisoa
Publisher: name: Zenodo
Year: 2022

description: NOvA is a long-baseline neutrino oscillation experiment with the primary physics goals of precisely measuring the neutrino oscillation parameters $theta_{23}$ and $Delta m^2_{32}$, determining the neutrino mass hierarchy, and constraining the value of $delta_{CP}$, primarily via the study of muon neutrino to electron neutrino oscillation. Extracting values for oscillation parameters from fits to data currently relies on treating systematic uncertainties as nuisance parameters, which suffers from poor scalability as the number of uncertainties becomes larger. In this poster we present PISCES (Parameter Inference with Systematic Covariance and Exact Statistics), a novel method that circumvents this scalability problem by encoding systematic uncertainties into a covariance matrix, and then considering them as an ensemble. PISCES has the advantage of supporting more complex fits, such as joint Near and Far Detector fits and is ideal for inclusion of low-statistics samples in the fits. This poster focuses particularly on the conditional PISCES method, an efficient approach in which the Near Detector observation is used to create a conditional covariance matrix, constraining systematic uncertainties for a Far Detector only fit.

description: In this paper, we show how to adapt and deploy anomaly detection algorithms based on deep autoencoders, for the unsupervised detection of new physics signatures in the extremely challenging environment of a real-time event selection system at the Large Hadron Collider (LHC). We demonstrate that new physics signatures can be enhanced by three orders of magnitude, while staying within the strict latency and resource constraints of a typical LHC event filtering system. This would allow for collecting datasets potentially enriched with high-purity contributions from new physics processes. Through per-layer, highly parallel implementations of network layers, support for autoencoder-specific losses on FPGAs and latent space based inference, we demonstrate that anomaly detection can be performed in as little as $80\,$ns using less than 3% of the logic resources in the Xilinx Virtex VU9P FPGA. Opening the way to real-life applications of this idea during the next data-taking campaign of the LHC.

description: We explore the sensitivity of directly testing the muon-Higgs coupling at a high-energy muon collider. This is strongly motivated if there exists new physics that is not aligned with the Standard Model Yukawa interactions which are responsible for the fermion mass generation. We illustrate a few such examples for physics beyond the Standard Model. With the accidentally small value of the muon Yukawa coupling and its subtle role in the high-energy production of multiple (vector and Higgs) bosons, we show that it is possible to measure the muon-Higgs coupling to an accuracy of ten percent for a 10 TeV muon collider and a few percent for a 30 TeV machine by utilizing the three boson production, potentially sensitive to a new physics scale about $Λ\sim 30-100$ TeV.

description: We wish to carry forward to higher dimensions the insightful and novel method of obtaining the Kerr metric proposed by one of us [Gen. Relativ. Gravit. 45, 2383 (2013)] for deriving the Myers-Perry rotating black hole metric. We begin with a flat spacetime metric written in oblate spheroidal coordinates (ellipsoidal geometry) appropriate for the inclusion of rotation, and then introduce arbitrary functions to introduce a gravitational potential due to mass, which are then determined by requiring that a massless particle experiences no acceleration, while a massive particle feels Newtonian acceleration at large r. We further generalize the method to include the cosmological constant Λ to obtain the MyersPerry de Sitter/antide Sitter black hole metric.

description: The next generation of large ground- and space-based optical telescopes will have segmented primary mirrors. Co-phasing the segments requires a sensitive wavefront sensor capable of measuring phase discontinuities. The Zernike wavefront sensor (ZWFS) is a passive wavefront sensor that has been demonstrated to sense segmented-mirror piston, tip, and tilt with picometer precision in laboratory settings. We present the first on-sky results of an adaptive optics fed ZWFS on a segmented aperture telescope, W.M. Keck Observatory's Keck II. Within the Keck Planet Imager and Characterizer (KPIC) light path, the ZWFS mask operates in the H-band using an InGaAs detector (CRED2). We piston segments of the primary mirror by a known amount and measure the mirror's shape using both the ZWFS and a phase retrieval method on data acquired with the facility infrared imager, NIRC2. In the latter case, we employ slightly defocused NIRC2 images and a modified Gerchberg-Saxton phase retrieval algorithm to estimate the applied wavefront error. We find good agreement when comparing the phase retrieval and ZWFS reconstructions, with average measurements of 408 +/- 23 nm and 394 +/- 46 nm, respectively, for three segments pistoned by 400 nm of optical path difference (OPD). Applying various OPDs, we are limited to 100 nm OPD of applied piston due to our observations' insufficient averaging of adaptive optics residuals. We also present simulations of the ZWFS that help explain the systematic offset observed in the ZWFS reconstructed data.

description: We present new HST imaging photometry for the site of the Type IIn supernova (SN) 2009ip taken almost a decade after explosion. The optical source has continued to fade steadily since the SN-like event in 2012. In the F606W filter, which was also used to detect its luminous blue variable (LBV) progenitor 13~yr before the SN, the source at the position of SN2009ip is now 1.2mag fainter than that quiescent progenitor. It is 6-7mag fainter than the pre-SN outbursts in 2009--2011. This definitively rules out a prediction that the source would return to its previous state after surviving the 2012 event. Instead, the late-time fading matches expectations for a terminal explosion. The source fades at a similar rate in all visual-wavelength filters without significant color changes, therefore also ruling out the hypothesis of a luminous dust-obscured survivor or transition to a hotter post-LBV survivor. The late-time continuum with steady color and strong H$α$ emission detected in a narrow F657N filter are, however, entirely expected for ongoing shock interaction with circumstellar material in a decade-old core-collapse SN. Interestingly, the ultraviolet flux has stayed nearly constant since 2015, supporting previous conjectures that the F275W light traces main-sequence OB stars in an underlying young star cluster. We expect that the visual-wavelength continuum will eventually level off, tracing this cluster light. Without any additional outbursts, it seems prudent to consider the 2012 event as a terminal SN explosion, and we discuss plausible scenarios.

description: Efficient numerical methods are promising tools for delivering unique insights into the fascinating properties of physics, such as the highly frustrated quantum many-body systems. However, the computational complexity of obtaining the wave functions for accurately describing the quantum states increases exponentially with respect to particle number. Here we present a novel convolutional neural network (CNN) for simulating the two-dimensional highly frustrated spin-$1/2$ $J_1-J_2$ Heisenberg model, meanwhile the simulation is performed at an extreme scale system with low cost and high scalability. By ingenious employment of transfer learning and CNN's translational invariance, we successfully investigate the quantum system with the lattice size up to $24\times24$, within 30 million cores of the new generation of sunway supercomputer. The final achievement demonstrates the effectiveness of CNN-based representation of quantum-state and brings the state-of-the-art record up to a brand-new level from both aspects of remarkable accuracy and unprecedented scales.

description: The search for extraterrestrial intelligence at radio frequencies has largely been focused on continuous-wave narrowband signals. We demonstrate that broadband pulsed beacons are energetically efficient compared to narrowband beacons over longer operational timescales. Here, we report the first extensive survey searching for such broadband pulsed beacons towards 1883 stars as a part of the Breakthrough Listen's search for advanced intelligent life. We conducted 233 hours of deep observations across 4 to 8 GHz using the Robert C. Byrd Green Bank Telescope and searched for three different classes of signals with artificial (or negative) dispersion. We report a detailed search -- leveraging a convolutional neural network classifier on high-performance GPUs -- deployed for the very first time in a large-scale search for signals from extraterrestrial intelligence. Due to the absence of any signal-of-interest from our survey, we place a constraint on the existence of broadband pulsed beacons in our solar neighborhood: $\lesssim$1 in 1000 stars have transmitter power-densities $\gtrsim$10$^5$ W/Hz repeating $\leq$500 seconds at these frequencies.

description: With the availability of large-scale surveys like Kepler and TESS, there is a pressing need for automated methods to classify light curves according to known classes of variable stars. We introduce a new algorithm for classifying light curves that compares 7000 time-series features to find those which most effectively classify a given set of light curves. We apply our method to Kepler light curves for stars with effective temperatures in the range 6500--10,000K. We show that the sample can be meaningfully represented in an interpretable five-dimensional feature space that separates seven major classes of light curves (delta Scuti stars, gamma Doradus stars, RR Lyrae stars, rotational variables, contact eclipsing binaries, detached eclipsing binaries, and non-variables). We achieve a balanced classification accuracy of 82% on an independent test set of Kepler stars using a Gaussian mixture model classifier. We use our method to classify 12,000 Kepler light curves from Quarter 9 and provide a catalogue of the results. We further outline a confidence heuristic based on probability density with which to search our catalogue, and extract candidate lists of correctly-classified variable stars.

title: Verflechtung von Politik und Sport im Kontext von Doping
Creators: name: Knyz, Werner

description: Die Verflechtung zwischen Sport und Politik im Kontext von Doping zeigt sich in der Darbietung von monetären Anreizen im Leistungssport bei gleichzeitigem Verbot vieler Leistungspräparate. Gleichzeitig nutzen Politiker oft erfolgreiche Athleten für politische Wahlkämpfe. Die finanzielle Grundlage für Sport-Förderung legen in manchen Fällen eben diese Politiker. Gemeinsam mit Sportverbänden üben sie auf Athleten soziale und pekuniäre Anreize aus, ihre sportliche Leistung zu verbessern. Diese Anreize können eine verstärkte Neigung zur Einnahme von Dopingmitteln nach sich ziehen. Eruiert wird, inwiefern Sportverbände von ihrer Verbindung zu Politikern in finanzieller Hinsicht profitieren können. Dabei werden auch die Reaktionen von Politikern auf Doping-Vorfälle diskutiert, bevor die Vorteile der Politiker aus ihrer Nähe zu Sportverbänden untersucht werden. Auf juristischer Ebene analysiert die Studie auch die Entwicklung der Anti-Doping Strategie der Republik Österreich. So lässt sich vergleichen, wie unterschiedlich die Politik auf Doping-Ereignisse reagiert und bei der Setzung von Anti-Doping Normen agiert.

description: We present an improved background model for the Large Area X-ray Proportional Counter (LAXPC) detectors on-board AstroSat. Because of the large collecting area and high pressure, the LAXPC instrument has a large background count rate, which varies during the orbit. Apart from the variation with latitude and longitude during the orbit there is a prominent quasi-diurnal variation which has not been modelled earlier. Using over 5 years of background observations, we determined the period of the quasi-diurnal variation to be 84495 s and using this period, it is possible to account for the variation and also identify time intervals where the fit is not good. These lead to a significant improvement in the background model. The quasi-diurnal variation can be ascribed to the changes in charged particle flux in the near Earth orbit.

description: Here, we describe a technique to define the Singularity Expansion Method (SEM) poles for short-circuited thin-wire structures developed using the Method of Modal Parameters (MoMP). The MoMP method consists of in the expansion of the system of mixed-potential integral equations (MPIE) into the Fourier series, including the kernels containing Green’s function. Corresponding equations for Fourier modes contain infinite matrices of p.u.l. inductance and capacitance, and the solution for current can be obtained using the infinity matrix of p.u.l. impedance. The SEM poles are given by the zeros of the determinant of this matrix. For the case of the symmetrical circular loop, this equation transforms to one well-know from the literature. Numerical investigation of solutions for the poles of the first layer has shown good agreement with previously obtained analytical and numerical results for different wire configurations.

description: Objetivo: Avaliar aspectos clínicos, diagnósticos e terapêuticos numa série de casos de pacientes com carcinoma de tireóide.

Métodos: Revisão de prontuários de crianças e adolescentes brasileiros com carcinoma de tireóide, atendidos em um hospital universitário, entre junho de 1992 e julho de 2005.

Resultados: Foram encontrados sete pacientes (5 do sexo feminino) com idade média de 12 anos. Nódulo tireoidiano foi a queixa inicial em cinco casos. Ultra-sonografia pré-operatória, realizada em cinco pacientes, mostrou nódulo sólido e hipoecogênico em três; nódulo isoecogênico em um e bócio multinodular com nódulos hipoecogênicos em outro. O tamanho médio dos nódulos foi de 20,6 mm. Punção aspirativa com agulha fina diagnosticou carcinoma papilífero em cinco casos e carcinoma medular em um. Biópsia de linfonodo cervical efetuada no sétimo paciente mostrou carcinoma papilífero metastático. Função tireoidiana pré-operatória foi obtida em quatro casos. Todos estavam eutireoideos. Todas crianças foram submetidas à tireoidectomia total. Quatro desenvolveram hipoparatireoidismo no pós-operatório. Terapia adjuvante com 131I foi necessária em quatro pacientes. O seguimento foi superior a cinco anos em três casos. Não houve relato de óbitos.

Conclusão: Esta casuística está de acordo com a literatura no que se refere ao predomínio do sexo feminino e ao tipo histológico do tumor. O diagnóstico de câncer tireoidiano deve ser considerado na investigação da criança e adolescente com nódulo tireoidiano.

description: The outflow of granular materials from storage containers with narrow outlets is studied by means of ultrafast x-ray computed tomography (UFXCT). The used acquisition speed of this tomograph is high enough to allow high-speed recording of two horizontal cross sections (each of them at a rate of 1000 images per second) of the container during the discharge of material. Analyzing space-time plots that were generated from the tomograms, we retrieve velocity profiles and packing structures in the container.Wecompare hard spherical grains with soft, low-friction hydrogel spheres. Their flow profiles are qualitatively different. While the hard spheres form stagnant zones at the container side walls, the hydrogel spheres with extremely low friction coefficient flow in all regions of the container. Moreover, a shell-like positional arrangement of the soft spheres induced by the container walls is revealed. The results obtained for the flow field structure confirm earlier conclusions drawn from sequences of x-ray tomograms of clogged states.

description: A doença de Rosai-Dorfman é uma patologia a considerar no diagnóstico diferencial de adenopatia cervical. Esta é uma doença rara, idiopática, benigna, mais frequente nas três primeiras décadas de vida. Aapresentação clínica predominante é linfadenopatia cervical, bilateral e indolor, surgindo em 28-43% com envolvimento extraganglionar. Evolui com exacerbações e remissões. O diagnóstico é anatomopatológico. O tratamento não é consensual, estando descrita corticoterapia, quimioterapia e radioterapia. Apresentamos dois casos, de um rapaz de seis anos e de uma jovem de quinze, com massa cervical de três meses e um ano de evolução, respectivamente, sem outros sintomas. Submetidos a cirurgia, para excisão no primeiro caso e biópsia no segundo, o exame anatomopatológico revelou tratar-se de Doença de Rosai-Dorfman.

description: Introdução: Em 1987, a Comissão Europeia começou a apoiar um programa de mobilidade para estudantes (chamado ERASMUS) entre universidades na Europa; a ideia central era dar oportunidades de os estudantes estudarem durante período definido no estrangeiro.

Objectivo: Analisar os testemunhos de estudantes estrangeiros realizando o bloco de pediatria na Clínica Universitária do Hospital Dona Estefânia em Lisboa, Portugal.

Métodos: O estudo baseou-se em dados obtidos de 28 estudantes de 7 diferentes países europeus durante 5 anos lectivos (2002-2007) principalmente através de: questionários distribuídos para todos os alunos do curso; discussões de grupo semi-estruturadas; e entrevistas individuais sob a orientação do catedrático da disciplina (JMVA); foram também colhidos dados do relatório de estágio e da base de dados do Departamento de Relações públicas da FCM/UNL.

Resultados: A maioria dos respondentes considerou o modelo de estágio integrando alunos nacionais e estrangeiros relevante, sendo que a totalidade gostaria que o estágio hospitalar tivesse maior duração. Foram identificados dois pontos fracos no período de treino clínico: dificuldade de comunicação com português fluente e notas mais baixas dos estudantes ERASMUS no exame final em relação aos seus
pares portugueses. Este último achado poderá sugerir que os estudantes portugueses têm melhor preparação teórica do que os primeiros.

Conclusão: Apesar de os dados obtidos serem qualitativos e susceptíveis de originarem interpretação envolvendo certa subjectividade, a experiência descrita sugere a necessidade de aperfeiçoamento organizativo em certas áreas tais como critérios de recrutamento e treino do português falado tendo em vista a motivação para uma melhor preparação dos candidatos.

description: O estado de mal epiléptico constitui a mais frequente emergência neurológica em idade pediátrica. A cascata de alterações fisiopatológicas desencadeada por uma convulsão prolongada pode conduzir a uma perda da autorregulação da circulação cerebral e lesões neurológicas irreversíveis. Os objectivos do tratamento do estado de mal são a ressuscitação, tratamento da causa primária e administração de anticonvulsivantes, assegurando ao mesmo tempo a identificação e tratamento das causas subjacentes. A Sociedade Portuguesa de Neuropediatria realizou em Setembro 2006 um inquérito às diversas Unidades de Neuropediatria do País, com vista a tentar estabelecer um consenso face a esta questão. As opções diagnósticas e terapêuticas foram discutidas e analisadas e surgiu esta proposta, que inclui
uma breve revisão teórica sobre esta entidade.

description: Stars in massive star clusters exhibit intrinsic variations in some light elements (MPs) that are difficult to explain in a coherent formation scenario. In recent years, HST photometry has led to the characterisation of the global properties of th MPs in an unparalleled level of detail. In particular, the colour-colour diagrams known as chromosome maps have been proven to be very efficient at separating cluster stars with field-like metal abundance distribution (1P) from object with distinctive light-element abundance anti-correlations (2P). The unexpected wide colour ranges covered by the 1P group in the chromosome maps of the majority of the investigated Galactic GCs have been recently attributed to intrinsic metallicity variations up to ~0.30 dex, from the study of SGB stars in two metal rich Galactic GCs by employing appropriate HST filter combinations. On the other hand, high-resolution spectroscopy of small samples of 1P stars in NGC 3201 and NGC 2808 have so far provided conflicting results, with a spread of metallicity detected in NGC 3201 but not in NGC 2808. We present a new method that employs HST near-UV and optical photometry of RGB stars, to independently confirm these results. Our approach has been firstly validated using observational data for M2, a GC hosting a small group of 1P stars with enhanced (by ~0.5 dex) metallicity with respect to the main component. We have then applied our method to three clusters that cover a much larger metallicity range, and have well populated, extended first population sequences in their chromosome maps, namely M92, NGC2808, and NGC6362. We confirm that metallicity spreads are present among 1P stars in these clusters, thus solidifying the case for the existence of unexpected variations up to a factor of two of metal abundances in most GCs. We also confirm the complex behaviour of the mean metallicity differences between 1P and 2P stars.
