description: Asteroseismology is a powerful tool to infer fundamental stellar properties. The use of these asteroseismic-inferred properties in a growing number of astrophysical contexts makes it vital to understand their accuracy. Consequently, we performed a hare-and-hounds exercise where the hares simulated data for 6 artificial main-sequence stars and the hounds inferred their properties based on different inference procedures. To mimic a pipeline such as that planned for the PLATO mission, all hounds used the same model grid. Some stars were simulated using the physics adopted in the grid, others a different one. The maximum relative differences found (in absolute value) between the inferred and true values of the mass, radius, and age were 4.32 per cent, 1.33 per cent, and 11.25 per cent, respectively. The largest systematic differences in radius and age were found for a star simulated assuming gravitational settling, not accounted for in the model grid, with biases of -0.88 per cent (radius) and 8.66 per cent (age). For the mass, the most significant bias (-3.16 per cent) was found for a star with a helium enrichment ratio outside the grid range. Moreover, a ~7 per cent dispersion in age was found when adopting different prescriptions for the surface corrections or shifting the classical observations by $\pm 1σ$. The choice of the relative weight given to the classical and seismic constraints also impacted significantly the accuracy and precision of the results. Interestingly, only a few frequencies were required to achieve accurate results on the mass and radius. For the age the same was true when at least one $l=2$ mode was considered.

description: We consider soliton solutions of a two-dimensional nonlinear system with the self-focusing nonlinearity and a quasi-1D confining potential, taking harmonic potential as an example. We investigate a single soliton in detail and find criterion for possible collapse. This information is then used to investigate the dynamics of the two soliton collision. In this dynamics we identify three regimes according to the relation between nonlinear interaction and the excitation energy: elastic collision, excitation and collapse regime. We show that surprisingly accurate predictions can be obtained from variational analysis.

Etude sur le Sentiment de l’Honneur dans les Chefs-d’Oeuvre de Pierre Corneille
Creators: name: Jukpor, Bernard K’Anene
Publisher: name: University of British Columbia
Year: 2010

description: Le sentiment de l'honneur est un thème qui paraît très souvent dans les oeuvres dramatiques de Pierre Corneille. Mais tout banal qu'il soit, cet honneur n'admet pas une définition simpliste car il a une nature essentiellement complexe. Par cette nature complexe, le sentiment de l'honneur chez Corneille pose déjà un problème: celui de sa; définition. Sa nature est complexe car l'honneur cornélien, entretient des rapports étroits avec les autres valeurs telles que gloire, devoir, générosité, orgueil, qui. sont également chères au dramaturge, et qui constituent la grande partie de son lexique. Il est vrai que chez Corneille l'honneur sert souvent de doublet à la gloire; mais sert-il aussi de doublet au devoir, à l'orgueil, à la générosité? S'il y a une association entre l'honneur et ces mots clefs, cette association est-elle incidente ou dominante? Si elle est incidente, elle n'interviendra dans les pièces que d'une manière secondaire, et peut-être inconsciente; mais elle y intervient (du moins dans les. quatre piècies étudiées) d'une manière permanente. Elle est donc dominante et même volontaire. Puisque cette association est volontaire, toute étude basée sur l'honneur devrait donc, nous semble-t-il, tenir compte de ces mots -devoirs, orgueil, générosité - car c'est à travers eux que l'honneur cornélien se manifeste. C'est pour cela que nous avons conçu notre étude sous trois chapitres distincts: l'honneur-devoir, l'honneur-orgueil et l'honneur-générosité. Et nous avons poursuivi cette étude en examinant etroitement comment cet honneur qui est la raison d'être des personnages cornéliens est recherché par eux. Ce qui ressort finalement de notre étude c'est que l'honneur- devoir se manifeste principalement chez les personnages par le désir de vengeance, tandis que l'honneur-orgueil se manifeste par l'ambition, d'être unique, et l'honneur-générosité par la naissance noble. Mais chez Corneille il n'y a que les gens de la race noble, c'est-à-dire les généreux qui se soucient de l'honneur. D'oïl il s'ensuit que la générosité est le point de départ de l'honneur cornélien.
Formation and evolution of disk galaxies

description: Global star formation is the key to understanding galaxy disk formation. This in turn depends on gravitational instability of disks and continuing gas accretion as well as minor merging. A key component is feedback from supernovae. Primary observational constraints on disk galaxy formation and evolution include the Schmidt-Kennicutt law, the Tully-Fisher relation and the galaxy luminosity function. I will review how theory confronts phenomenology, and discuss future prospects for refining our understanding of disk formation.

Observables in terms of connection and curvature variables for Einstein's equations with two commuting Killing vectors

description: Einstein's equations with two commuting Killing vectors and the associated Lax pair are considered. The equations for the connection $A(ς, η, γ)=Ψ_{,γ}Ψ^{-1}$, where $γ$ the variable spectral parameter are considered. A transition matrix ${\cal T}= A(ς, η, γ)A^{-1}(ξ, η, γ)$ for $A$ is defined relating $A$ at ingoing and outgoing light cones. It is shown that it satisfies equations familiar from integrable pde's theory. A transition matrix on $ς={\mbox constant}$ is defined in an analogous manner. These transition matrices allow us to obtain a hierarchy of integrals of motion with respect to time, purely in terms of the trace of a function of the connections $g_{,ς}g^{-1}$ and $g_{,η}g^{-1}$. Furthermore a hierarchy of integrals of motion in terms of the curvature variable $B=A_{,γ}A^{-1}$, involving the commutator $[A(1), A(-1)]$, is obtained. We interpret the inhomogeneous wave equation that governs $σ=ln N$, $N$ the lapse, as a Klein-Gordon equation, a dispersion relation relating energy and momentum density, based on the first connection observable and hence this first observable corresponds to mass. The corresponding quantum operators are $\frac{\partial}{\partial t}$, $\frac{\partial}{\partial z}$ and this means that the full Poincare group is at our disposal.

description: Quantum mechanical scattering involving continuum states coupled to a scatterer with a discrete spectrum gives rise to Fano resonances. Here we consider scatterers that possess internal vibrational degrees of freedom in addition to discrete states. Entanglement between the scattered excitation and vibrational modes complicates analytical and numerical calculations considerably. For the example of one-dimensional scattering we develop a multichannel quantum scattering approach which can determine reflection and transmission probabilities in the presence of vibrations. Application to a linear chain coupled to a control unit containing vibrating sites shows that vibrational degrees of freedom can have a profound effect on quantum transport. For suitable parameters, spectral regions which are opaque in the static case can be rendered transparent when vibrations are included. The formalism is general enough to be applicable to a variety of platforms for quantum transport including molecular aggregates, cold atom chains, quantum-dot arrays and molecular wires based on conjugated polymers.

description: By using a single formalism to handle charm, strange and light valence quarks in full lattice QCD for the first time, we are able to determine ratios of quark masses to 1%. For $m_c/m_s$ we obtain 11.85(16), an order of magnitude more precise than the current PDG average. Combined with 1% determinations of the charm quark mass now possible this gives $\bar{m}_s(2{\rm GeV}) =$ 92.4(1.5) MeV. The MILC result for $m_s/m_l = 27.2(3) $ yields $\bar{m}_l(2{\rm GeV})$ = 3.40(7) MeV for the average of $u$ and $d$ quark masses.
description: 4 pages, 2 figures. Version accepted by Physical Review Letters. Changes include modifying the title, using the MILC value for m_s/m_l which changes slightly the resulting up and down quark masses and their average, adding some references and making other small adjustments to the text for space reasons.

description: It is theoretically justified and experimentally confirmed that the effectiveness of polymer composite modifiers depends on the temperature and time regime of their application, in the case under consideration in relation to asphalt concrete. First of all, the adhesive strength of the binder's connection with other fractions of the composite depends on this. The optimal values of temperature and process time depend on the nature and brand of the materials used. A method has been developed for determining the characteristics of the binder, which must be known in order to perform practical calculations.

description: Let Q be a finite quiver without oriented cycles, let Λbe the associated preprojective algebra, let g be the associated Kac-Moody Lie algebra with Weyl group W, and let n be the positive part of g. For each Weyl group element w, a subcategory C_w of mod(Λ) was introduced by Buan, Iyama, Reiten and Scott. It is known that C_w is a Frobenius category and that its stable category is a Calabi-Yau category of dimension two. We show that C_w yields a cluster algebra structure on the coordinate ring \CC[N(w)] of the unipotent group N(w) := N \cap (w^{-1}N_-w). Here N is the pro-unipotent pro-group with Lie algebra the completion of n. One can identify \CC[N(w)] with a subalgebra of the graded dual of the universal enveloping algebra U(n) of n. Let S^* be the dual of Lusztig's semicanonical basis S of U(n). We show that all cluster monomials of \CC[N(w)] belong to S^*, and that S^* \cap \CC[N(w)] is a basis of \CC[N(w)]. Moreover, we show that the cluster algebra obtained from \CC[N(w)] by formally inverting the generators of the coefficient ring is isomorphic to the algebra \CC[N^w] of regular functions on the unipotent cell N^w := N \cap (B_-wB_-) of the Kac-Moody group G with Lie algebra g. We obtain a corresponding dual semicanonical basis of \CC[N^w]. As one application we obtain a basis for each acyclic cluster algebra, which contains all cluster monomials in a natural way.

description: We investigate tunneling properties of Bogoliubov mode in a Bose-Einstein condensate. Using an exactly solvable model with a delta-functional barrier, we show that each component in the two-component wavefunction (u,v) of low-energy Bogoliubov phonon has the same form as the condensate wavefunction in the supercurrent state. As a result, the currents J_u and J_v associated with u and v, respectively, have the same tunneling properties as those of supercurrent carried by condensate. Thus, the tunneling of low-energy Bogoliubov phonon described by the tunneling of these two currents shows perfect transmission. We also show that the supercurrent behaviors of Bogoliubov phonon still exist in the presence of supercurrent carried by condensate, except in the critical supercurrent state. In the critical current state, the perfect transmission is absent, because J_u or J_v exceeds their upper limit given by the critical value of the supercurrent associated with the condensate. Our results consistently explain the recently proposed two tunneling phenomena associated with Bogoliubov phonon, namely, the anomalous tunneling effect (perfect transmission in the low-energy limit) and the breakdown of the perfect transmission in the critical supercurrent state.

description: A cookie banner pops up when a user visits a website for the first time, requesting consent to the use of cookies and other trackers for a variety of purposes. Unlike prior work that has focused on evaluating the user interface (UI) design of cookie banners, this paper presents an in-depth analysis of what cookie banners say to users to get their consent. We took an interdisciplinary approach to determining what cookie banners should say. Following the legal requirements of the ePrivacy Directive (ePD) and the General Data Protection Regulation (GDPR), we manually annotated around 400 cookie banners presented on the most popular English-speaking websites visited by users residing in the EU. We focused on analyzing the purposes of cookie banners and how these purposes were expressed (e.g., any misleading or vague language, any use of jargon). We found that 89% of cookie banners violated applicable laws. In particular, 61% of banners violated the purpose specificity requirement by mentioning vague purposes, including "user experience enhancement". Further, 30% of banners used positive framing, breaching the freely given and informed consent requirements. Based on these findings, we provide recommendations that regulators can find useful. We also describe future research directions.

description: We propose a new node centrality measure in networks, the lobby index, which is inspired by Hirsch's h-index. It is shown that in scale free networks the l-index has power tail with exponent square of the exponent of the degree distribution one. Properties of the l-index and extensions are discussed.

description: The distribution of information is essential for living system's ability to coordinate and adapt. Random walkers are often used to model this distribution process and, in doing so, one effectively assumes that information maintains its relevance over time. But the value of information in social and biological systems often decay and must continuously be updated. To capture the spatial dynamics of ageing information, we introduce time walkers. A time walker moves like a random walker, but interacts with traces left by other walkers, some representing older information, some newer. The traces forms a navigable information landscape. We quantify the dynamical properties of time walkers moving on a two-dimensional lattice and the quality of the information landscape generated by their movements. We visualise the self-similar landscape as a river network, and show that searching in this landscape is superior to random searching and scales as the length of loop-erased random walks.

ABSTRACTAt the beginning of the 21st century, as rapid urbanization becomes a global phenomenon, smart city becoming more and more a future-proof solution for cities with rising unprecedented challenges of congested infrastructure, population density, energy inefficiency and global public health. In this context, digital twin was initially introduced by Dr Michael Grieves in 2002 as a key enabler technology to improve product manufacture and complex systems, and later bloomed as a new concept to promote better design, system integration and troubleshooting of the physical city through simulation, automation and visualisation. This paper, in aiming to understand how digital twin was rapidly adopted by a number of pioneer entrepreneurs, cities and nations, provides a narrative and categorical perspective of digital twin appearance in literature and explores the extents where a real-time cyber presentation of the city can support mediating urban issues within the context of global pandemic. In result, a longitudinal section of digital twin and smart city development has been introduced, including the evolvement of digital model, digital shadows to digital twin, as well as the rising interest of academia and private sector to the technology.

description: The popularity of the Java programming language has led to its wide adoption in cloud computing infrastructures. However, Java applications running in untrusted clouds are vulnerable to various forms of privileged attacks. The emergence of trusted execution environments (TEEs) such as Intel SGX mitigates this problem. TEEs protect code and data in secure enclaves inaccessible to untrusted software, including the kernel and hypervisors. To efficiently use TEEs, developers must manually partition their applications into trusted and untrusted parts, in order to reduce the size of the trusted computing base (TCB) and minimise the risks of security vulnerabilities. However, partitioning applications poses two important challenges: (i) ensuring efficient object communication between the partitioned components, and (ii) ensuring the consistency of garbage collection between the parts, especially with memory-managed languages such as Java. We present Montsalvat, a tool which provides a practical and intuitive annotation-based partitioning approach for Java applications destined for secure enclaves. Montsalvat provides an RMI-like mechanism to ensure inter-object communication, as well as consistent garbage collection across the partitioned components. We implement Montsalvat with GraalVM native-image, a tool for compiling Java applications ahead-of-time into standalone native executables that do not require a JVM at runtime. Our extensive evaluation with micro- and macro-benchmarks shows our partitioning approach to boost performance in real-world applications

Model-based pattern speed estimates for 38 barred galaxies

description: We have modelled 38 barred galaxies by using near-IR and optical data from the Ohio State University Bright Spiral Galaxy Survey. We constructed the gravitational potentials of the galaxies from $H$-band photometry, assuming constant mass-to-light ratio. The halo component we chose corresponds to the so called universal rotation curve. In each case, we used the response of gaseous and stellar particle disc to rigidly rotating potential to determine the pattern speed. We find that the pattern speed of the bar depends roughly on the morphological type. The average value of corotation resonance radius to bar radius, $\mathcal{R}$, increases from $1.15 \pm 0.25$ in types SB0/a -- SBab to $1.44 \pm 0.29$ in SBb and $1.82\pm 0.63$ in SBbc -- SBc. Within the error estimates for the pattern speed and bar radius, all galaxies of type SBab or earlier have a fast bar ($\mathcal{R} \le 1.4$), whereas the bars in later type galaxies include both fast and slow rotators. Of 16 later type galaxies with a nominal value of $\mathcal{R} > 1.4$, there are five cases, where the fast rotating bar is ruled out by the adopted error estimates. We also study the correlation between the parameter $\mathcal{R}$ and other galactic properties. The clearest correlation is with the bar size: the slowest bars are also the shortest bars when compared to the galaxy size. A weaker correlation is seen with bar strength in a sense that slow bars tend to be weaker. These correlations leave room for a possibility that the determined pattern speed in many galaxies corresponds actually that of the spiral, which rotates more slowly than the bar. No clear correlation is seen with either the galaxy luminosity or colour.

description: Spin-active quantum emitters have emerged as a leading platform for quantum technologies. However, one of their major limitations is the large spread in optical emission frequencies, which typically extends over tens of GHz. Here, we investigate single V4+ vanadium centres in 4H-SiC, which feature telecom-wavelength emission and a coherent S=1/2 spin state. We perform spectroscopy on single emitters and report the observation of spin-dependent optical transitions, a key requirement for spin-photon interfaces. By engineering the isotopic composition of the SiC matrix, we reduce the inhomogeneous spectral distribution of different emitters down to 100 MHz, significantly smaller than any other single quantum emitter. Additionally, we tailor the dopant concentration to stabilise the telecom-wavelength V4+ charge state, thereby extending its lifetime by at least two orders of magnitude. These results bolster the prospects for single V emitters in SiC as material nodes in scalable telecom quantum networks.

description: Numerous observations suggest that there exist undiscovered beyond-the-Standard-Model particles and fields. Because of their unknown nature, these exotic particles and fields could interact with Standard Model particles in many different ways and assume a variety of possible configurations. Here we present an overview of the Global Network of Optical Magnetometers for Exotic physics searches (GNOME), our ongoing experimental program designed to test a wide range of exotic physics scenarios. The GNOME experiment utilizes a worldwide network of shielded atomic magnetometers (and, more recently, comagnetometers) to search for spatially and temporally correlated signals due to torques on atomic spins from exotic fields of astrophysical origin. We survey the temporal characteristics of a variety of possible signals currently under investigation such as those from topological defect dark matter (axion-like particle domain walls), axion-like particle stars, solitons of complex-valued scalar fields (Q-balls), stochastic fluctuations of bosonic dark matter fields, a solar axion-like particle halo, and bursts of ultralight bosonic fields produced by cataclysmic astrophysical events such as binary black hole mergers.

description: For the task of image classification, researchers work arduously to develop the next state-of-the-art (SOTA) model, each bench-marking their own performance against that of their predecessors and of their peers. Unfortunately, the metric used most frequently to describe a model's performance, average categorization accuracy, is often used in isolation. As the number of classes increases, such as in fine-grained visual categorization (FGVC), the amount of information conveyed by average accuracy alone dwindles. While its most glaring weakness is its failure to describe the model's performance on a class-by-class basis, average accuracy also fails to describe how performance may vary from one trained model of the same architecture, on the same dataset, to another (both averaged across all categories and at the per-class level). We first demonstrate the magnitude of these variations across models and across class distributions based on attributes of the data, comparing results on different visual domains and different per-class image distributions, including long-tailed distributions and few-shot subsets. We then analyze the impact various FGVC methods have on overall and per-class variance. From this analysis, we both highlight the importance of reporting and comparing methods based on information beyond overall accuracy, as well as point out techniques that mitigate variance in FGVC results.
