description: We calculate the cross section for the $γγ\to J/ψJ/ψ$ process. Two mechanisms are considered: box (two-loop) diagrams of the order of $O(α_{em}^2 α_s^2)$ and two-gluon exchange of the order of $O(α_{em}^2 α_s^4)$. The first mechanism is calculated in the heavy-quark non-relativistic approximation while the second case we also include the effects of quantum motion of quarks in the bound state. The box contribution dominates at energies close to the threshold ($W $ 15 GeV. Including the bound-state wave function effects for the two-gluon exchange mechanism gives a cross section 0.1 - 0.4 pb, substantially smaller than that in the non-relativistic limit (0.4 - 1.6 pb). We also find a strong infrared sensitivity which manifests itself in a rather strong dependence on the mass for the $t$-channel gluons. The elementary cross section is then used in the Equivalent Photon Approximation (EPA) in the impact parameter space to calculate the cross section for $^{208}Pb+^{208}Pb \to ^{208}Pb + J/ψJ/ψ+ ^{208}Pb$ reaction. Distributions in rapidity of the $J/ψJ/ψ$ pair and invariant mass of the pair are shown.

description: Um sistema de cobertura final do tipo barreira capilar consiste em uma camada fina sobre uma camada grossa, ambas com diferentes propriedades hidráulicas não saturadas. Uma das aplicações de este sistema é proteger da percolação de água os aterros de resíduos sólidos urbanos, rejeitos de mineração, resíduos nucleares, entre outros. Em este artigo se avaliam as características geotécnicas de uma Argila e um resíduo da construção e demolição (RCD) visando sua utilização conjunta como barreira capilar. Amostras indeformadas e amolgadas da argila e RCD foram coletadas de uma cobertura pré-existente e levadas ao laboratório para sua respectiva caracterização. Os resultados mostraram um importante potencial como barreira capilar de estes materiais em conjunto, importantes faixas das curvas de função de condutividade hidráulica mostram o RCD com uma menor condutividade hidráulica que a Argila. A argila mostrou uma razoável capacidade de armazenamento de água possibilitando seu funcionamento também como cobertura evapotranspirativa.

description: GaN nanowires (NWs) grown by molecular beam epitaxy on Ti films sputtered on Al$_{2}$O$_{3}$ are studied by X-ray diffraction (XRD) and grazing incidence small-angle X-ray scattering (GISAXS). XRD, performed both in symmetric Bragg reflection and at grazing incidence, reveals Ti, Ti$_{3}$O, Ti$_{3}$Al, and TiO$_x$N$_y$ crystallites with in-plane and out-of-plane lattice parameters intermediate between those of Al$_{2}$O$_{3}$ and GaN. These topotaxial crystallites in Ti film, formed due to interfacial reactions and N exposure, possess fairly little misorientation with respect to Al$_{2}$O$_{3}$. As a result, GaN NWs grow on the top TiN layer possessing a high degree of epitaxial orientation with respect to the substrate. The measured GISAXS intensity distributions are modeled by the Monte Carlo method taking into account the orientational distributions of NWs, a variety of their cross-sectional shapes and sizes, and roughness of their side facets. The cross-sectional size distributions of the NWs and the relative fractions of $(1\bar{1}00)$ and $(11\bar{2}0)$ side facets are determined.
Tangential contacts of three-dimensional power-law graded elastic solids: A general theory and application to partial slip

description: A rigorous theory for solving tangential contacts between three-dimensional power-law graded elastic solids of arbitrary geometry is presented. For multiple contacts such as those occurring between two nominally flat but rough half-spaces, the well-known Ciavarella-Jäger theorem is established accompanied by a discussion of tangential coupling. Nevertheless, the focus of the work is on axisymmetric single contacts under arbitrary unidirectional tangential loading, for which closed-form analytical solutions are derived based on the Mossakovskii-Jäger procedure. In comparison to the results of common approximate methods, the solutions include the non-axisymmetric components of tangential displacements, which are indispensable for the accurate determination of the relative slip components and thus the surface density of frictional energy dissipation in the partial slip regime. Although a simplified approach is used for the calculation of the dissipated energy density, the results in the limiting case of homogeneous material are in excellent agreement with those from a full numerical computation. As an application example, the complete solutions for the tangential contact of parabolically shaped power-law graded elastic solids in the partial slip regime are derived and the influence of the material gradient as well as Poisson's ratio on the surface density of dissipated energy is investigated.

description: Several highly luminous Type Ia supernovae (SNe Ia) have been discovered. Their high luminosities are difficult to explain with the thermonuclear explosions of the Chandrasekhar-mass white dwarfs (WDs). In the present study, we estimate the progenitor mass of SN 2009dc, one of the extremely luminous SNe Ia, using the hydrodynamical models as follows. Explosion models of super-Chandrasekhar-mass (super-Ch-mass) WDs are constructed, and multi-color light curves (LCs) are calculated. The comparison between our calculations and the observations of SN 2009dc suggests that the exploding WD has a super-Ch mass of 2.2-2.4 solar masses, producing 1.2-1.4 solar masses of Ni-56, if the extinction by its host galaxy is negligible. If the extinction is significant, the exploding WD is as massive as \sim2.8 solar masses, and \sim1.8 solar masses of Ni-56 is necessary to account for the observations. Whether the host-galaxy extinction is significant or not, the progenitor WD must have a thick carbon-oxygen layer in the outermost zone (20-30% of the WD mass), which explains the observed low expansion velocity of the ejecta and the presence of carbon. Our estimate on the mass of the progenitor WD, especially for the extinction-corrected case, is challenging to the current scenarios of SNe Ia. Implications on the progenitor scenarios are also discussed.

description: Real-world events generate a massive amount of traffic on social media with live, moment-to-moment accounts as any given situation unfolds. The data generated on social media is loaded with the sentiment, opinions, and reactions of the public towards the events. Browsing the event-related data in its raw form would be an overwhelming task due to the extensive amount of data, making the search for any specific updates or useful information an especially daunting and time-consuming endeavor. Event-related data, if effectively summarized, could generate a comprehensive overview of the event in terms of what happened and how people reacted at the time. Unfortunately, most of the event-based summarization systems concentrate their effort on simply describing what happened during the event; ignoring a valuable resource of emotional reactions that portrays the event from varying perspectives. Accordingly, in this thesis, we introduce an event-based summarization approach that incorporates multimedia data, sentiment, and human reactions with respect to their point of view in order to generate a concise subjective multimedia summary of the event. In order to achieve our goal, we introduce popularity prediction and sentiment analysis models, both of which are essential in our summarization approach. As the event unfolds over time, we utilize the popularity prediction model to extract a representative set of images for the event to be included in the summary based on the predicted popularity scores. Multi-modality features are exploited to develop our model, including various levels of visual features, textual features, and contextual features. In order to track users' opinions and changes in their sentiment in correlation with the occurrence of sub-events, we develop a sentiment classification model that effectively recognizes the sentiment conveyed in sport conversations. Due to the lack of a manually annotated sentiment dataset, we propose a new, manually labeled football-based sentiment dataset. We also create an automatically generated sentiment-lexicon specifically for the football domain. We assess the performance of our developed models and generated summary through extensive experimental evaluation. We explore the impact of different features on the performance of the popularity prediction and sentiment models. We also leverage the knowledge of sport fans to evaluate the generated subjective summarization through an online user-based survey. The experiment results confirm the effectiveness of our proposed solution for event-based summarization by considering multimedia data, sentiment, and people's subjective views of events.

description: This note concerns the so-called pyjama problem, whether it is possible to cover the plane by finitely many rotations of vertical strips of half-width $\varepsilon$. We first prove that there exist no periodic coverings for $\varepsilon<1/3$. Then we describe an explicit (non-periodic) construction for $\varepsilon =1/3-1/48$. Finally, we use a compactness argument combined with some ideas from additive combinatorics to show that a finite covering exists for $\varepsilon =1/5$. The question whether $\varepsilon$ can be arbitrarily small remains open.

description: Network structure is a mechanism for promoting cooperation in social dilemma games. In the present study, we explore graph surgery, i.e., to slightly perturb the given network, towards a network that better fosters cooperation. To this end, we develop a perturbation theory to assess the change in the propensity of cooperation when we add or remove a single edge to/from the given network. Our perturbation theory is for a previously proposed random-walk-based theory that provides the threshold benefit-to-cost ratio, $(b/c)^*$, which is the value of the benefit-to-cost ratio in the donation game above which the cooperator is more likely to fixate than in a control case, for any finite networks. We find that $(b/c)^*$ decreases when we remove a single edge in a majority of cases and that our perturbation theory captures at a reasonable accuracy which edge removal makes $(b/c)^*$ small to facilitate cooperation. In contrast, $(b/c)^*$ tends to increase when we add an edge, and the perturbation theory is not good at predicting the edge addition that changes $(b/c)^*$ by a large amount. Our perturbation theory significantly reduces the computational complexity for calculating the outcome of graph surgery.

description: This essay proposes a typology of political orders that emerge in the wake of secessionist insurgencies and counterinsurgencies. In addition, it offers a theory of why different political orders result in different circumstances, based on the interaction of structural and ideological factors at work in such insurgent wars. By examining four secessionist insurgencies in India vz. Kashmir, Punjab, Assam and Nagaland, the essay argues that definitive political order resulted in Punjab, and not the other three states, because the structural factors favouring the insurgency had become detrimental, and the ideological pull of the secessionist vision had become diluted--an outcome that hasn't resulted in the other three states.

description: We consider collective excitations in the superfluid state of Fermi condensed charged gases. The dispersion and damping of collective excitations at nonzero temperatures are examined, and the coexistence and interaction of different branches of collective excitations: plasma oscillations, pair-breaking Higgs modes, and Carlson-Goldman phonon-like excitations are taken into account. The path integral methods for superfluid Fermi gases and for Coulomb gas are combined into a unified formalism that extends the Gaussian fluctuation approximation to account for plasmonic modes. This approximation of Gaussian pair and density fluctuations is able to describe all branches of collective excitations existing in a charged superfluid. The spectra of collective excitations are determined in two ways: from the spectral functions and from the complex poles of the fluctuation propagator. A resonant avoided crossing of different modes is shown. It is accompanied by resonant enhancement of the response provided by the pair-breaking modes due to their interaction with plasma oscillations. This may facilitate the experimental observation of the pair-breaking modes.

description: The most famous 2-dimensional continued fraction algorithm is the Jacobi algorithm. However, Brun and Selmer algorithms are also interesting 2-dimensional subtractive algorithms. Schratzberger shows that all these three algorithms are deeply related by a process similar to insertion and extension for continued fractions. In this note the basic ergodic properties of two mixtures of both maps are explored. Furthermore a digression to a quite different map is made which exhibits an "exotic" invariant measure.

description: We consider geometric constraints for the addition of carbon atoms to the rim of a growing nanotube. The growth of a tube proceeds through the conversion of dangling bonds from armchair to zigzag and vice versa. We find that the growth rate depends on the rim structure (chirality), the energy barriers for dangling bond conversion, and the growth temperature. A calculated chirality distribution derived from this minimalistic theory shows surprisingly good agreement with experiment. Our ideas imply that the chirality distribution of carbon nanotubes can be influenced by external parameters.

description: In the present paper, direct numerical simulation (DNS) and particle image velocimetry (PIV) have been applied complementarily in order to generate a database of near-wall turbulence properties of a highly turbulent jet impinging on a solid surface under different inclination angles. Thereby, the main focus is placed on an impingement angle of 45°, since it represents a good generic benchmark test case for a wide range of technical fluid flow applications. This specific configuration features very complex flow properties including the presence of a stagnation point, development of the shear boundary layer and strong streamline curvature. In particular, this database includes near-wall turbulence statistics along with mean and rms velocities, budget terms in the turbulent kinetic energy equation, anisotropy invariant maps, turbulent length/time scales and near-wall shear stresses. These properties are useful for the validation of near-wall modeling approaches in the context of Reynolds-averaged Navier–Stokes (RANS) and large-eddy simulations (LES). From this study, in which further impingement angles (0°, 90°) have been considered in the experiments only, it turns out that (1) the production of turbulent kinetic energy appears negative at the stagnation point for an impingement angle other than 0° and is balanced predominantly by pressure-related diffusion, (2) quasi-coherent thin streaks with large characteristic time scales appear at the stagnation region, while the organization of the flow is predominantly toroidal further downstream, and (3) near-wall shear stresses are low at the stagnation region and intense in regions where the direction of the flow changes suddenly.

description: The present article examines Michel Houellebecq’s novel Soumission (Submission, 2015) with reference to the special role played by the study of literature in today’s society and the various tasks it needs to fulfill. The story reveals a crisis surrounding literary studies seen through the eyes of its protagonist François, himself a professor of literature at Paris III. The crisis becomes palpable through professors who are merely concerned with their own research projects while ignoring any political or social changes. With respect to the next presidential election in 2022, the academic elite is portrayed as idiosyncratic, isolated and indifferent. Thus Soumission can be regarded as an overall criticism of universities and a threatening future scenario of literary science. Nevertheless, beyond Houellebecq’s fictional world, the controversial response following the novel’s reception clearly demonstrates a need for this branch of science and may even be seen as an appeal for literary studies to become more involved in public discussion.

description: It has been proved that in gapped ground states of locally-interacting quantum systems, the effect of local perturbations decays exponentially with distance. However, in systems with power-law ($1/r^α$) decaying interactions, no analogous statement has been shown, and there are serious mathematical obstacles to proving it with existing methods. In this paper we prove that when $α$ exceeds the spatial dimension $D$, the effect of local perturbations on local properties a distance $r$ away is upper bounded by a power law $1/r^{α_1}$ in gapped ground states, provided that the perturbations do not close the spectral gap. The power-law exponent $α_1$ is tight if $α>2D$ and interactions are two-body, where we have $α_1=α$. The proof is enabled by a method that avoids the use of quasiadiabatic continuation and incorporates techniques of complex analysis. This method also improves bounds on ground state correlation decay, even in short-range interacting systems. Our work generalizes the fundamental notion that local perturbations have local effects to power-law interacting systems, with broad implications for numerical simulations and experiments.

description: Dynamic polarization control (DPC) is beneficial for many optical applications. It uses adjustable waveplates to perform automatic polarization tracking and manipulation. Efficient algorithms are essential to realizing an endless polarization control process at high speed. However, the standard gradientbased algorithm is not well analyzed. Here we model the DPC with a Jacobian-based control theory framework that finds a lot in common with robot kinematics. We then give a detailed analysis of the condition of the Stokes vector gradient as a Jacobian matrix. We identify the multi-stage DPC as a redundant system enabling control algorithms with null-space operations. An efficient, reset-free algorithm can be found. We anticipate more customized DPC algorithms to follow the same framework in various optical systems.
The Stationary Phase Approximation, Time-Frequency Decomposition and Auditory Processing

description: The principle of stationary phase (PSP) is re-examined in the context of linear time-frequency (TF) decomposition using Gaussian, gammatone and gammachirp filters at uniform, logarithmic and cochlear spacings in frequency. This necessitates consideration of the use the PSP on non-asymptotic integrals and leads to the introduction of a test for phase rate dominance. Regions of the TF plane that pass the test and don't contain stationary phase points contribute little or nothing to the final output. Analysis values that lie in these regions can thus be set to zero, i.e. sparsity. In regions of the TF plane that fail the test or are in the vicinity of stationary phase points, synthesis is performed in the usual way. A new interpretation of the location parameters associated with the synthesis filters leads to: (i) a new method for locating stationary phase points in the TF plane; (ii) a test for phase rate dominance in that plane. Together this is a TF stationary phase approximation (TFSFA) for both analysis and synthesis. The stationary phase regions of several elementary signals are identified theoretically and examples of reconstruction given. An analysis of the TF phase rate characteristics for the case of two simultaneous tones predicts and quantifies a form of simultaneous masking similar to that which characterizes the auditory system.

description: A significant body of recent research in the field of Learning Analytics has focused on leveraging machine learning approaches for predicting at-risk students in order to initiate timely interventions and thereby elevate retention and completion rates. The overarching feature of the majority of these research studies has been on the science of prediction only. The component of predictive analytics concerned with interpreting the internals of the models and explaining their predictions for individual cases to stakeholders has largely been neglected. Additionally, works that attempt to employ data-driven prescriptive analytics to automatically generate evidence-based remedial advice for at-risk learners are in their infancy. eXplainable AI is a field that has recently emerged providing cutting-edge tools which support transparent predictive analytics and techniques for generating tailored advice for at-risk students. This study proposes a novel framework that unifies both transparent machine learning as well as techniques for enabling prescriptive analytics, while integrating the latest advances in large language models. This work practically demonstrates the proposed framework using predictive models for identifying at-risk learners of programme non-completion. The study then further demonstrates how predictive modelling can be augmented with prescriptive analytics on two case studies in order to generate human-readable prescriptive feedback for those who are at risk using ChatGPT.

This, in turn, motivated the selection of a Sabbath offense that is analogous to Exod 16:27. Under this conception, the insertion of Num 15:32–36 basically fits even better within its context than the rather loosely bound together laws otherwise characteristic of this chapter. It thereby ensures that »law and narrative« in Num 10:10–17:28 in the final analysis form a meaningful.

description: In the last decade Cherenkov telescopes on the ground and space-based γ-ray instruments have identified a new class of high mass X-ray binaries (HMXB), whose emission is dominated by γrays. To date only five of these systems are known. All of them are detected by Cherenkov telescopes in the TeV energy range, while at GeV energies there is still one (HESS J0632+057) that has no reported detection with the Fermi-LAT. A deep search for γ-ray emission of HESS J0632+057 has been performed using more than 3.5 years of Fermi-LAT data. We discuss the results of this search and compare it to other γ-ray binary systems.

description: We study the differential cross sections for electroweak gauge-boson and Higgs production at small and very small transverse-momentum q_T. Large logarithms are resummed using soft-collinear effective theory. The collinear anomaly generates a non-perturbative scale q_*, which protects the processes from receiving large long-distance hadronic contributions. A numerical comparison of our predictions with data on the transverse-momentum distribution in Z-boson production at the Tevatron and LHC is given.

description: Analyzing relational data consisting of multiple samples or layers involves critical challenges: How many networks are required to capture the variety of structures in the data? And what are the structures of these representative networks? We describe efficient nonparametric methods derived from the minimum description length principle to construct the network representations automatically. The methods input a population of networks or a multilayer network measured on a fixed set of nodes and output a small set of representative networks together with an assignment of each network sample or layer to one of the representative networks. We identify the representative networks and assign network samples to them with an efficient Monte Carlo scheme that minimizes our description length objective. For temporally ordered networks, we use a polynomial time dynamic programming approach that restricts the clusters of network layers to be temporally contiguous. These methods recover planted heterogeneity in synthetic network populations and identify essential structural heterogeneities in global trade and fossil record networks. Our methods are principled, scalable, parameter-free, and accommodate a wide range of data, providing a unified lens for exploratory analyses and preprocessing large sets of network samples.

description: We study the level spacing distribution for the spectrum of a point scatterer on a flat torus. In the 2-dimensional case, we show that in the weak coupling regime the eigenvalue spacing distribution coincides with that of the spectrum of the Laplacian (ignoring multiplicties), by showing that the perturbed eigenvalues generically clump with the unperturbed ones on the scale of the mean level spacing. We also study the three dimensional case, where the situation is very different.

Wafer-Scale Fast Fourier Transforms

description: We have implemented fast Fourier transforms for one, two, and three-dimensional arrays on the Cerebras CS-2, a system whose memory and processing elements reside on a single silicon wafer. The wafer-scale engine (WSE) encompasses a two-dimensional mesh of roughly 850,000 processing elements (PEs) with fast local memory and equally fast nearest-neighbor interconnections. Our wafer-scale FFT (wsFFT) parallelizes a $n^3$ problem with up to $n^2$ PEs. At this point a PE processes only a single vector of the 3D domain (known as a pencil) per superstep, where each of the three supersteps performs FFT along one of the three axes of the input array. Between supersteps, wsFFT redistributes (transposes) the data to bring all elements of each one-dimensional pencil being transformed into the memory of a single PE. Each redistribution causes an all-to-all communication along one of the mesh dimensions. Given the level of parallelism, the size of the messages transmitted between pairs of PEs can be as small as a single word. In theory, a mesh is not ideal for all-to-all communication due to its limited bisection bandwidth. However, the mesh interconnecting PEs on the WSE lies entirely on-wafer and achieves nearly peak bandwidth even with tiny messages. This high efficiency on fine-grain communication allow wsFFT to achieve unprecedented levels of parallelism and performance. We analyse in detail computation and communication time, as well as the weak and strong scaling, using both FP16 and FP32 precision. With 32-bit arithmetic on the CS-2, we achieve 959 microseconds for 3D FFT of a $512^3$ complex input array using a 512x512 subgrid of the on-wafer PEs. This is the largest ever parallelization for this problem size and the first implementation that breaks the millisecond barrier.
“Black-eyed Bastard”

description: Dishonored is not only one of the most popular and original game series on the market, but from a religious point of view it has one of the most complex and original fictional belief systems. A character that particularly stands out is the Outsider, a mysterious divine-like entity that interacts with all main playable characters, giving them supernatural abilities and commenting on their choices. He inhabits a mysterious otherworld called Void, containing everything supernatural, chaotic, magical and irrational. The Outsider also indirectly affects the ‘human world’ by figuring in underground cults and their opponents, creating an interesting mosaic of religious teachings and struggles. In this article, we would like to examine the Outsider both in the context of the game lore and comparative religion studies, with emphasis on the analysis of his character and its parallels in world mythologies.

description: This volume contains the final and revised versions of the papers presented at the 8th International Workshop on Automated Specification and Verification of Web Systems (WWV 2012). The workshop was held in Stockholm, Sweden, on June 16, 2012, as part of DisCoTec 2012. WWV is a yearly workshop that aims at providing an interdisciplinary forum to facilitate the cross-fertilization and the advancement of hybrid methods that exploit concepts and tools drawn from Rule-based programming, Software engineering, Formal methods and Web-oriented research. WWV has a reputation for being a lively, friendly forum for presenting and discussing work in progress. The proceedings have been produced after the symposium to allow the authors to incorporate the feedback gathered during the event in the published papers. All papers submitted to the workshop were reviewed by at least three Program Committee members or external referees. The Program Committee held an electronic discussion leading to the acceptance of all papers for presentation at the workshop. In addition to the presentation of the contributed papers, the scientific programme included the invited talks by two outstanding speakers: Rocco De Nicola (IMT, Institute for Advanced Studies Lucca, Italy) and Josè Luiz Fiadeiro (Royal Holloway, United Kingdom).

How well-intentioned white male physicists maintain ignorance of inequity and justify inaction

description: Background: We present an analysis of interviews with 27 self-identified progressive white-male physics faculty and graduate students discussing race and gender in physics. White men dominate most STEM fields and are particularly overrepresented in positions of status and influence (i.e. full professors, chairs, deans, etc.), positioning them as a potentially powerful demographic for enacting systemic reform. Despite their proclaimed outrage at and interest in addressing inequity, they frequently engage in patterns of belief, speech and (in)action that ultimately support the status quo of white male privilege in opposition to their intentions. Results: The white male physicists we interviewed used numerous discourses which support racist and sexist norms and position them as powerless to disrupt their own privilege. We present and discuss three overarching themes, seen in our data, demonstrating how highly intelligent, well-intentioned people of privilege maintain their power and privilege despite their own intentions: 1) Denying inequity is physically near them, 2) Locating causes of inequity in large societal systems over which they have little influence and 3) Justifying inaction. Conclusions: Despite being progressively minded, well-meaning, and highly intelligent, these men are frequently complicit in racism and sexism in physics. We end with recommendations for helping these men to engage the power they hold to better work with women and people of color in disrupting inequity in physics.

description: We present numerical simulations of high-order harmonic generation in helium using a temporally synthesised and spatially non-homogeneous strong laser field. The combination of temporal and spatial laser field synthesis results in a dramatic cut-off extension far beyond the usual semiclassical limit. Our predictions are based on the convergence of three complementary approaches: resolution of the three dimensional Time Dependent Schrödinger Equation, time-frequency analysis of the resulting dipole moment and classical trajectories extraction. Employing a combination of temporally and spatially synthesised laser field provides coherent XUV photons beyond the carbon K-edge which is of high interest for initiating inner-shell dynamics and study time-resolved intra-molecular attosecond spectroscopy.
