description: Abstract

Introduction: Neuroblastoma ranks as the most prevalent extracranial solid tumor in infants (1). While typically sporadic, familial occurrences have been documented (2). Originating from primitive neuroblasts of the embryonic neural crest, neuroblastoma can manifest anywhere within the sympathetic nervous system (3). The primary tumor is most frequently located in the abdomen, with approximately 65% of cases occurring there, half of which arise from the adrenal medulla. Other common sites include the neck, chest, and pelvis (4). There's no established association between prenatal or postnatal exposure to drugs, chemicals, or radiation and increased neuroblastoma incidence. Prognosis tends to worsen with advancing age. Treatment approaches encompass various modalities such as surgery, chemotherapy, radiotherapy, biotherapy, and, in select cases, careful observation alone (5). Case report: A 15 months female presented with complaints of abdominal distension and non-passage of stool in 3 days, with history of chronic constipation. On examination, abdomen was distended with pallor and hypertension. Management: Roentgenogram was suggestive of dilated fecal filled bowel loops. USG abdomen confirmed the above and revealed a retroperitoneal mass. Contrast enhanced CT abdomen was done which was suggestive of neuroblastoma. Blood investigations revealed severe anemia (Hb - 5.4 g/dl) and leukocytosis (TLC 20,450 cells/cumm - N60 L32), GBP was suggestive of microcytic hypochromic anemia with leukocytosis. Patient was managed with blood transfusion and other supportive treatment. Child was started on first cycle of chemotherapy and is doing well on follow-up. Conclusion: Neuroblastomas can manifest with subtle and nonspecific symptoms, potentially leading to misdiagnosis or overlooked cases. Thus, in children experiencing chronic constipation of uncertain origin, the potential for neuroblastoma should be taken into account.

description: We study anharmonic localization in a periodic five atom chain with quadratic-quartic spring potential. We use discrete symmetries to eliminate the degeneracies of the harmonic chain and easily find periodic orbits. We apply linear stability analysis to measure the frequency of phonon-like disturbances in the presence of breathers and to analyze the instabilities of breathers. We visualize the phase plane of breather motion directly and develop a technique for exciting pinned and moving breathers. We observe long-lived breathers that move chaotically and a global transition to chaos that prevents forming moving breathers at high energies.

description: Given the complexity of typical data science projects and the associated demand for human expertise, automation has the potential to transform the data science process. Key insights: * Automation in data science aims to facilitate and transform the work of data scientists, not to replace them. * Important parts of data science are already being automated, especially in the modeling stages, where techniques such as automated machine learning (AutoML) are gaining traction. * Other aspects are harder to automate, not only because of technological challenges, but because open-ended and context-dependent tasks require human interaction.

Cosserat elasticity as the weak-field limit of Einstein--Cartan relativity

description: The weak-field limit of Einstein--Cartan (EC) relativity is studied. The equations of EC theory are rewritten such that they formally resemble those of Einstein General Relativity (EGR); this allows ideas from post-Newtonian theory to be imported without essential change. The equations of motion are then written both at first post-Newtonian (1PN) order and at 1.5PN order. EC theory's 1PN equations of motion are found to be those of a micropolar/Cosserat elastic medium, along with a decoupled evolution equation for non-classical, spin-related fields. It seems that a necessary condition for these results to hold is that one chooses the non-classical fields to scale with the speed of light in a certain empirically reasonable way. Finally, the 1.5PN equations give greater insight into the coupling between energy-momentum and spin within slowly moving, weakly gravitating matter. Specifically, the weakly relativistic modifications to Cosserat theory involve a gravitational torque and an augmentation of the gravitational force due to a `dynamic mass moment density' with an accompanying `dynamic mass moment density flux', and new forms of linear momentum density captured by a `dynamic mass density flux' and a `dynamic momentum density'.

description: High Purity Germanium Detectors have excellent energy resolution; the best among the technologies used in double beta decay. Since neutrino-less double beta decay hinges on the search for a rare peak upon a background continuum, this strength has enabled the technology to consistently provide leading results. The Ge crystals at the heart of these experiments are very pure; they have no measurable U or Th contamination. The added efforts to reduce the background associated with electronics, cryogenic cooling, and shielding have been very successful, leading to the longevity of productivity. The first experiment published in 1967 by the Milan group of Fiorini, established the benchmark half-life limit $>3\times10^{20}$ yr. More recently, the \MJ\ and GERDA collaborations have developed new detector technologies that optimize the pulse waveform analysis. As a result, the GERDA collaboration refuted the claim of observation with a revolutionary approach to shielding by immersing the detectors directly in radio-pure liquid argon. In 2018, the \MJ\ collaboration, using a classic vacuum cryostat and high-Z shielding, achieved a background level near that of GERDA by developing very pure materials for use nearby the detectors. Together, GERDA and \MJ\ have provided limits approaching $10^{26}$ yr. In this article, we elaborate on the historical use of Ge detectors for double beta decay addressing the strengths and weaknesses. We also summarize the status and future as many \MJ\ and GERDA collaborators have joined with scientists from other efforts to give birth to the LEGEND collaboration. LEGEND will exploit the best features of both experiments to extend the half-life limit beyond $10^{28}$ yr with a ton-scale experiment.

description: Trapped ions form an advanced technology platform for quantum information processing with long qubit coherence times, high-fidelity quantum logic gates, optically active qubits, and a potential to scale up in size while preserving a high level of connectivity between qubits. These traits make them attractive not only for quantum computing but also for quantum networking. Dedicated, special-purpose trapped-ion processors in conjunction with suitable interconnecting hardware can be used to form quantum repeaters that enable high-rate quantum communications between distant trapped-ion quantum computers in a network. In this regard, hybrid traps with two distinct species of ions, where one ion species can generate ion-photon entanglement that is useful for optically interfacing with the network and the other has long memory lifetimes, useful for qubit storage, have been proposed for entanglement distribution. We consider an architecture for a repeater based on such dual-species trapped-ion systems. We propose and analyze a protocol based on spatial and temporal mode multiplexing for entanglement distribution across a line network of such repeaters. Our protocol offers enhanced rates compared to rates previously reported for such repeaters. We determine the ion resources required at the repeaters to attain the enhanced rates, and the best rates attainable when constraints are placed on the number of repeaters and the number of ions per repeater. Our results bolster the case for near-term trapped-ion systems as quantum repeaters for long-distance quantum communications.

We show that for each of the groups $\mathbb{Z}/2\mathbb{Z} \times \mathbb{Z}/k\mathbb{Z}$ for $k = 2, 4, 6, 8$, there are infinitely many rational Diophantine quadruples with the property that the induced elliptic curve has this torsion group. We also construct curves with moderately large rank in each of these four cases.

description: An exact analysis is performed for the two-point correlation function C(r,t) in dissipative Burgers turbulence with bounded initial data, in arbitrary spatial dimension d. Contrary to the usual scaling hypothesis of a single dynamic length scale, it is found that C contains two dynamic scales: a diffusive scale l_{D} \sim t^{1/2} for very large r, and a super-diffusive scale L(t) \sim t^{a} for r \ll l_{D}, where a = (d+1)/(d+2). The consequences for conventional scaling theory are discussed. Finally, some simple scaling arguments are presented within the `toy model' of disordered systems theory, which may be exactly mapped onto the current problem.

description: Canada and the European Union (EU) are preparing to ratify a trade agreement that can be described as historic. Canada will be the only economy in the world to have privileged access to the world's two largest economies, accounting for nearly 45% of global GDP: the EU and the United States. The Comprehensive Economic and Trade Agreement (CETA) is often defined as a second generation agreement, i.e. one that focuses more on the establishment of collaborative mechanisms than a simple free trade agreement. It will bring the Canadian and Quebec economies closer to the EU economy. The virtual elimination of tariff barriers and the significant reduction of non-tariff barriers will increase the competitiveness of Canadian companies in Europe.This book is intended for researchers, managers and policy makers interested in Canada's and Quebec's trade profile with the European Union at the time of the CETA.

description: Scientist learn early on how to cite scientific sources to support their claims. Sometimes, however, scientists have challenges determining where a citation should be situated -- or, even worse, fail to cite a source altogether. Automatically detecting sentences that need a citation (i.e., citation worthiness) could solve both of these issues, leading to more robust and well-constructed scientific arguments. Previous researchers have applied machine learning to this task but have used small datasets and models that do not take advantage of recent algorithmic developments such as attention mechanisms in deep learning. We hypothesize that we can develop significantly accurate deep learning architectures that learn from large supervised datasets constructed from open access publications. In this work, we propose a Bidirectional Long Short-Term Memory (BiLSTM) network with attention mechanism and contextual information to detect sentences that need citations. We also produce a new, large dataset (PMOA-CITE) based on PubMed Open Access Subset, which is orders of magnitude larger than previous datasets. Our experiments show that our architecture achieves state of the art performance on the standard ACL-ARC dataset ($F_{1}=0.507$) and exhibits high performance ($F_{1}=0.856$) on the new PMOA-CITE. Moreover, we show that it can transfer learning across these datasets. We further use interpretable models to illuminate how specific language is used to promote and inhibit citations. We discover that sections and surrounding sentences are crucial for our improved predictions. We further examined purported mispredictions of the model, and uncovered systematic human mistakes in citation behavior and source data. This opens the door for our model to check documents during pre-submission and pre-archival procedures. We make this new dataset, the code, and a web-based tool available to the community.

description: Active regions (ARs) appear in the solar atmosphere as a consequence of the emergence of magnetic flux-ropes (FR). In this study, we use Bayesian methods to analyze line-of-sight magnetograms of emerging ARs. We employ a FR model consisting of a half-torus field structure based on eight parameters. The goal is to derive constrained physical parameters of the originating FR which are consistent with the observations. Specifically, we aim to obtain a precise estimation of the AR tilt angle and magnetic twist at different stages of the emergence process. To achieve this, we propose four temporal methods that correlate the field parameter evolutions with a single coherent FR. These methods differ from each other in the size of the explored parameter space. We test the methods on four bipolar ARs observed with the Michelson Doppler Imager on board the Solar and Heliospheric Observatory. We find that tilt angles are typically consistent between the temporal methods, improving previous estimations at all stages of the emergence. The twist sign derived from the temporal methods is consistent with previous estimations. The standard errors of all the methods used are similar, indicating that they model the observations equally well. These results indicate that the proposed methods can be used to obtain global magnetic parameters of ARs during their early evolution. The derived parameters contribute to a better understanding of the formation of FRs, and the role of ARs in the magnetic recycling process along the solar cycle.

description: Quantum fields in cosmological spacetimes can experience particle production due to their interaction with the expanding background. This effect is particularly relevant for models of the very early Universe, when the energy density generated through this process may back-react on the cosmological expansion. Yet, these scenarios have not been fully explored due to the several technical hurdles imposed by the back-reaction calculations. In this work we review the basics of cosmological quantum particle production and demonstrate a numerical algorithm to solve the back-reaction problem in regimes dominated by particle production. As an illustration, we compute the effects of a massive quantized scalar field on a cosmological bounce scenario, explicitly showing that quantum particle production can cause the contracting phase to end in a radiation crunch, or can delay the bounce. Finally, we discuss the relevance of quantum particle production/annihilation to bounce and inflationary models of the early Universe.

description: In Einstein-Cartan theory, by the use of the general Noether theorem, the general covariant angular-momentum conservation law is obtained with the respect to the local Lorentz transformations. The corresponding conservative Noether current is interpreted as the angular momentum tensor of the gravity-matter system including the spin density. It is pointed out that, assuming the tetrad transformation given by eq. (15), torsion tensor can not play a role in the conservation law of angular momentum.

description: In the light of a recently derived evolution equation for genetic algorithms we consider the schema theorem and the building block hypothesis. We derive a schema theorem based on the concept of effective fitness showing that schemata of higher than average effective fitness receive an exponentially increasing number of trials over time. The equation makes manifest the content of the building block hypothesis showing how fit schemata are constructed from fit sub-schemata. However, we show that generically there is no preference for short, low-order schemata. In the case where schema reconstruction is favored over schema destruction large schemata tend to be favored. As a corollary of the evolution equation we prove Geiringer's theorem.

Ambiguity in Privacy Policies and Perceived Privacy Risk

Subjects: subject: 80399 Computer Software not elsewhere classified
subject: FOS: Computer and information sciences

description: Software designers and engineers make use of software specifications to design and develop a software system. Software specifications are generally expressed in natural language and are thus subject to its underlying ambiguity. Ambiguity in these specifications could lead to different stakeholders, including the software designers, regulators and users having different interpretations of the behavior and functionality of the system. One example where policy and specification overlap is when the data practices in the privacy polices describe the website’s functionality such as collection of particular types of user data to provide a service. Website companies describe their data practices in their privacy policies and these data practices should not be
inconsistent with the website’s specification. Software designers can use these data practices to inform the design of the website, regulators align these data practices
with government regulations to check for compliance, and users can use these data practices to better understand what the website does with their information and make
informed decisions about using the services provided by the website. In order to summarize their data practices comprehensively and accurately over multiple types
of products and under different situations, and to afford flexibility for future practices these website companies resort to using ambiguity in describing their data practices.
This ambiguity in data practices thus undermines its utility as an effective way to inform software design choices, or act as a regulatory mechanism, and does not give the users an accurate description of corporate data practices, thus increasing the perceived privacy risk for the user.
In this thesis, we propose a theory of ambiguity to understand, identify, and measure ambiguity in data practices described in the privacy policies of website companies. In addition, we also propose an empirically validated framework to measure the associated privacy risk perceived by users due to ambiguity in natural language.
This theory and framework could benefit the software designers by helping them better align the functionality of the website with the company data practices described
in privacy policies, and the policy writers by providing them linguistic guidelines to help them write unambiguous policies.

description: The optical depth parameterisation is typically used to study the 21-cm signals associated with the properties of the neutral hydrogen (HI) gas and the ionisation morphology during the Epoch of Reionisation (EoR), without solving the radiative transfer equation. To assess the uncertainties resulting from this simplification, we conduct explicit radiative transfer calculations using the cosmological 21-cm radiative transfer (C21LRT) code and examine the imprints of ionisation structures on the 21-cm spectrum. We consider a globally averaged reionisation history and implement fully ionised cavities (HII bubbles) of diameters $d$ ranging from 0.01 Mpc to 10 Mpc at epochs within the emission and the absorption regimes of the 21-cm global signal. The single-ray C21LRT calculations show that the shape of the imprinted spectral features are primarily determined by $d$ and the 21-cm line profile, which is parametrised by the turbulent velocity of the HI gas. It reveals the spectral features tied to the transition from ionised to neutral regions that calculations based on the optical depth parametrisation were unable to capture. We also present analytical approximations of the calculated spectral features of the HII bubbles. The multiple-ray calculations show that the apparent shape of a HII bubble (of $d=5$ Mpc at $z=8$), because of the finite speed of light, differs depending on whether the bubble's ionisation front is stationary or expanding. Our study shows the necessity of properly accounting for the effects of line-continuum interaction, line broadening and cosmological expansion to correctly predict the EoR 21-cm signals.

description: Acoustic flat lensing is achieved here by tuning a phononic array to have indefinite medium behaviour in a narrow frequency spectral region along the acoustic branch. This is confirmed by the occurrence of a flat band along an unusual path in the Brillouin zone and by interpreting the intersection point of isofrequency contours on the corresponding isofrequency surface; coherent directive beams are formed whose reflection from the array surfaces create lensing. Theoretical predictions are corroborated by time-domain experiments, airborne acoustic waves generated by a source with a frequency centered about $10.6$ kHz, placed at three different distances from one side of a finite phononic crystal slab, constructed from polymeric spheres, yield distinctive focal spots on the other side. These experiments evaluate the pressure field using optical feedback interferometry and demonstrate precise control of the three-dimensional wave trajectory through a sonic crystal.

description: No standard procedure is available for low temperature asphalt binder testing in the Dynamic Shear Rheometer. In this study, an overview is given of the necessary equipment to use the 4 mm geometry for asphalt binder testing including an explanation of shear compliance correction. Furthermore, the testing conditions of 4 mm geometry including specimen preparation, specimen conditions and test parameter are evaluated. Additionally, practical tips and screenshots on the implementation of recommended parameters and testing conditions in the software rSpace and RheoCompass are provided. Overall, this paper provides extended information and guidelines on how to use the 4 mm geometry and which testing conditions to consider for testing asphalt binder in the low temperature range.

description: In this letter we will show that, contrary to what is widely believed, an almost isotropic cosmic microwave background (CMB) temperature does not imply that the universe is ``close to a Friedmann-Lemaitre universe''. There are two important manifestations of anisotropy in the geometry of the universe, (i) the anisotropy in the overall expansion, and (ii) the intrinsic anisotropy of the gravitational field, described by the Weyl curvature tensor, although the former usually receives more attention than the latter in the astrophysical literature. Here we consider a class of spatially homogeneous models for which the anisotropy of the CMB temperature is within the current observational limits but whose Weyl curvature is not negligible, i.e. these models are not close to isotropy even though the CMB temperature is almost isotropic.

description: This study explores the combustion characteristics of a single cylinder four stroke variable compression ratio direct injection diesel engine run by Nahar biodiesel (BD) and its six different blends (B5, B10, B20, B30, B40, and B50). Combustion duration reduced up to B40 and slightly increased for B50 and significantly for B100. Peak cylinder pressure (PCP) increased with BD concentration in the blend. Maximum rate of pressure rise (MROPR), heat release rate, and ignition delay (ID) reduced with an increase in BD share in the blend. At full load, PCP for B100 is obtained as 70.91 bar, whereas for diesel it is 70.04 bar. The MROPR is observed to be 5.67 bar/°CA for diesel, whereas 5.31 bar/°CA for B100 at full load. Peak heat release rate is observed to be 64.7 J/°CA for diesel, whereas it is 54.41 J/°CA for B100. ID for the blends reduced by 1–2°CA compared to diesel fuel. Overall, it is recommended to use BD up to B40 blend in a DI diesel engine primarily employed in gen sets and agricultural units. Abbreviation: BD: Biodiesel; DF: Diesel fuel

description: We study the problem of Luttinger liquids interacting with an active environment. We are particularly interested in how dissipation affects the response and correlation functions of non-isolated Luttinger liquids. We show that the exchange of particles, energy, and momentum lead to changes in the exponents characterizing the various correlations functions. We discuss the importance of the zero mode physics in this context.

description: Whispering gallery modes in a microwire are characterized by a nearly equidistant energy spectrum. In the strong exciton-photon coupling regime, this system represents a bosonic cascade: a ladder of discrete energy levels that sustains stimulated transitions between neighboring steps. In this work, by using femtosecond angle-resolved spectroscopic imaging technique, the ultrafast dynamics of polaritons in a bosonic cascade based on a one-dimensional ZnO whispering gallery microcavity is explicitly visualized. Clear ladder-form build-up process from higher to lower energy branches of the polariton condensates are observed, which are well reproduced by modeling using rate equations. Moreover, the polariton parametric scattering dynamics are distinguished on a timescale of hundreds of femtoseconds. Our understanding of the femtosecond condensation and scattering dynamics paves the way towards ultrafast coherent control of polaritons at room temperature, which will make it promising for high-speed all-optical integrated applications.

description: We prove that the smallest degree of an apolar 0-dimensional scheme of a general cubic form in $n+1$ variables is at most $2n+2$, when $n\geq 8$, and therefore smaller than the rank of the form. For the general reducible cubic form the smallest degree of an apolar subscheme is $n+2$, while the rank is at least $2n$.
description: We thank Joachim Jelisiejew for pointing out that Lemma 2 is correct as stated only when using apolarity by contraction (as reflected in the current version of this paper, updated in May 2024) instead of apolarity by differentiation (as it was in the originally published version)

description: Die Entwicklung neuartiger Antriebskonzepte im Luftverkehr spielt eine zentrale Rolle hinsichtlich der Erreichung der Emissionsreduktionsziele des Flightpath 2050. So sollen bis zum Jahr 2050 pro Personenkilometer die Emissionen an C02 um 75%, an NOx um 90% und an Lärm um 65% reduziert werden. Die Erreichung dieser ehrgeizigen Ziele soll dabei helfen, den globalen Temperaturanstieg auf 1,5 Grad Celsius über dem vorindustriellen Niveau zu begrenzen, wie es im Abkommen von Paris festgelegt ist. Um diese Ziele zu erreichen, bedarf es jedoch eines Umdenkens hinsichtlich der Flugzeugantriebe. Trotz Effizienzsteigerungen von bis zu 2% jährlich und verbesserten Materialzusammensetzungen ist eine Erreichung des Flightpath 2050 unter Verwendung konventioneller kerosinbetriebener Turbinen nicht realistisch. Vielmehr müssen die aktuellen Konzepte weiterentwickelt und neue Konzepte auf Basis von Batterien und Brennstoffzellen erforscht werden. Eine mögliche technologische Weiterentwicklung, ohne große strukturelle Umbauten der Flugzeugarchitektur sowie hohen Investitionen, ist die Verwendung von synthetischen Kraftstoffen wie Power-to-Liquid oder Biokraftstoffen. Diese können konventionelles Kerosin ersetzen und so die Emissionen während des Flugbetriebs reduzieren. Jedoch stellt sich hier die Frage, ob die Verwendung solcher synthetischen Kraftstoffe langfristig zur Zielerreichung des Flightpath 2050 beitragen kann. Zudem ist die Synthese der Kraftstoffe mit hohen Kosten verbunden und kann sich negativ auf die lokale Bevölkerung auswirken, wie es etwa bei der Kultivierung von Pflanzen für die Herstellung von Biokraftstoffen der Fall ist. Daher muss zunächst analysiert werden, welche Kraftstoffalternative vor dem Hintergrund von Nachhaltigkeitsaspekten am besten geeignet ist. Um dies zu untersuchen, bedarf es einer ausführlichen Nachhaltigkeitsbewertung. Vor diesem Hintergrund hat Herr Timo Bley im Rahmen seiner Masterarbeit die Aufgabe, verschiedene Kraftstoffvarianten für die Verwendung im Luftverkehr hinsichtlich ökologischer und sozioökonomischer Umweltwirkungen zu analysieren und zu bewerten. Hierbei soll zunächst der aktuelle Stand der Forschung im Bereich synthetischer Kraftstoffe erläutert und eine Literaturrecherche zur lebenszyklusorientierten Nachhaltigkeitsbewertung durchgeführt werden. Im Anschluss sollen die identifizierten Kraftstoffvarianten hinsichtlich ihrer Produktion und letztlichen Verwendung im Flugbetrieb unter Verwendung geeigneter Software modelliert, analysiert und bewertet werden.

description: We study series of the stationary solutions with asymptotic flatness properties in the Einstein-Maxwell-free scalar system because they are locally equivalent with the exterior solutions in some class of the scalar-tensor theories of gravity. First, we classify spherical exterior solutions into two types of the solutions, an apparently black hole type solution and an apparently worm hole type solution. The solutions contain three parameters, and we clarify their physical significance. Second, we reduce the field equations for the axisymmetric exterior solutions. We find that the reduced equations are partially the same as the Ernst equations. As simple examples, we derive new series of the static, axisymmetric exterior solutions, which correspond to Voorhees's solutions. We then show a non-trivial relation between the spherical exterior solutions and our new solutions. Finally, since null geodesics have conformally invariant properties, we study the local geometry of the exterior solutions by using the optical scalar equations and find some anomalous behaviors of the null geodesics.
