description: We present an exponentially convergent numerical method to approximate the solution of the Cauchy problem for the inhomogeneous fractional differential equation with an unbounded operator coefficient and Caputo fractional derivative in time. The numerical method is based on the newly obtained solution formula that consolidates the mild solution representations of sub-parabolic, parabolic and sub-hyperbolic equations with sectorial operator coefficient $A$ and non-zero initial data. The involved integral operators are approximated using the sinc-quadrature formulas that are tailored to the spectral parameters of $A$, fractional order $α$ and the smoothness of the first initial condition, as well as to the properties of the equation's right-hand side $f(t)$. The resulting method possesses exponential convergence for positive sectorial $A$, any finite $t$, including $t = 0$ and the whole range $α\in (0,2)$. It is suitable for a practically important case, when no knowledge of $f(t)$ is available outside the considered interval $t \in [0, T]$. The algorithm of the method is capable of multi-level parallelism. We provide numerical examples that confirm the theoretical error estimates.

description: We study quantized non-local order parameters, constructed by using partial time-reversal and partial reflection, for fermionic topological phases of matter in one spatial dimension protected by an orientation reversing symmetry, using topological quantum field theories (TQFTs). By formulating the order parameters in the Hilbert space of state sum TQFT, we establish the connection between the quantized non-local order parameters and the underlying field theory, clarifying the nature of the order parameters as topological invariants. We also formulate several entanglement measures including the entanglement negativity on state sum spin TQFT, and describe the exact correspondence of the entanglement measures to path integrals on a closed surface equipped with a specific spin structure.

Efficient Scheduling for the Massive Random Access Gaussian Channel

Publisher: name: arXiv
Year: 2019
Subjects: subject: Information Theory (cs.IT)
subject: FOS: Computer and information sciences

description: This paper investigates the massive random access Gaussian channel with a focus on small payloads. For this problem, grant-based schemes have been regarded as inefficient due to the necessity of large feedbacks and the use of inefficient scheduling request methods. This papers attempts to answer whether grant-based schemes can be competitive against state-ot-art grantless schemes and worthy of further investigation. In order to compare these schemes fairly, a novel model is proposed, and, under this model, a novel grant-based scheme is proposed. The scheme uses Ordentlich and Polyanskiy's grantless method to transmit small coordination indices in order to perform the scheduling request, which allows both the request from the users to be efficient and the feedback to be small. We also present improvements to the Ordentlich and Polyanskiy's scheme, allowing it to transmit information through the choice of sub-block, as well as to handle collisions of the same message, significantly improving the method for very small messages. Simulation results show that, if a small feedback is allowed, the proposed scheme performs closely to the state-of-art while using simpler coding schemes, suggesting that novel grant-based schemes should not be dismissed as a potential solution to the massive random access problem.

NEW MATERIAL: 1♀, 13; Vietnam, Kien Giang Province, Phu Quoc Island, Khu Rung Nguyen Sinh Forest Reserve, stream ca. 5 km southwest of Bai Thom Beach, evergreen rainforest, 100-400 m; 14./ 16.VIII.2003; P.J.

 REMARKS: Otacilia kao is a pale species with extremely elongated and slender legs. There is a modest variation between the male holotype and the newly collected spiders examined and treated in the present study. The apex of the retrolateral tibial apophysis is slightly different from that of the male holotype (Figs 35, 37). The new male’s palpal configuration closely resembles that of O. sinifera and O. kao in having a simple, curved embolus and a minute conductor (Figs 35-36), but O. sinifera can be distinguished by the apex of the retrolateral tibial apophysis being hook-shaped, in addition to its conspicuous opisthosomal pattern. The shape of the retrolateral tibial apophysis in all three species seems to be somewhat similar, so it is difficult to make a conclusion about the taxonomic value of this character. They can be considered as a rather compact group of closely related species. It is possible that O. kao is a species with strong variability within the species and within its populations. However, the variation found in the new males is well within the known limits of the species and is not sufficient to warrant the status of a new taxon.

Through the Big Bang in inflationary cosmology

Year: 2019
Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)
subject: FOS: Physical sciences

description: Singularities in General Relativity are regions where the description of spacetime in terms of a pseudo-Riemannian geometry breaks down. The theory seems unable to predict the evolution of the physical degrees of freedom around and beyond such regions. In a recent paper, the author and collaborators challenged this view by providing an example of a singularity at which Einstein's equations can be rewritten in a form that satisfies an existence and uniqueness theorem, thereby predicting that each solution can be continued uniquely through the singularity. This result was obtained under the assumption of homogeneity (but not isotropy), and requires the presence of a massless free scalar field. This paper extends the result to N scalar fields with a potential, the only requirement being that it does not grow too fast. In particular, the result is compatible with inflationary potentials, e.g. Starobinsky's. This brings us one step closer to the goal of extending the original result to realistic cosmologies.

description: The presence of massive galaxies at high $z$ as recently observed by JWST appears to contradict the current $Λ$CDM cosmology. Here we aim to alleviate this tension by incorporating uncertainties from three sources in counting galaxies: cosmic variance, error in stellar mass estimation, and backsplash enhancement. Each of these factors significantly increases the cumulative stellar mass density $ρ_*(>M_*)$ at the high-mass end, and their combined effect can boost the density by more than one order of magnitude. Assuming a star formation efficiency of $ε_* \sim 0.5$, cosmic variance alone reduces the tension to a $2σ$ level, except for the most massive galaxy at $z=8$. Additionally, incorporating a 0.3 dex lognormal dispersion in the stellar mass estimation brings the observed $ρ_*(>M_*)$ at $z \sim 7 - 10$ within $2σ$. The tension is completely eliminated when we account for the gas stripped from backsplash halos. These results highlight the importance of fully modeling uncertainties when interpreting observational data of rare objects. We use the constrained simulation, ELUCID, to investigate the descendants of high-$z$ massive galaxies. Our findings reveal that a significant portion of these galaxies ultimately reside in massive halos at $z=0$ with $M_{\rm halo} > 10^{13} h^{-1}M_\odot$. Moreover, a large fraction of local central galaxies in $M_{\rm halo} \geqslant 10^{14.5} h^{-1}M_\odot$ halos are predicted to contain substantial amounts of ancient stars formed in massive galaxies at $z \sim 8$. This prediction can be tested by studying the structure and stellar population of central galaxies in present-day massive clusters.

description: Among the magnetostrictive alloys the one formed of iron and gallium (called "Galfenol" from its U.S. Office of Naval Research discoverers in the late 90's) is attractive for its low hysteresis, good tensile stress, good machinability and its rare-earth free composition. One of its applications is its association with a piezoelectric material to form a extrinsic multiferroic composite as an alternative to the rare room temperature intrinsic multiferroics such as BiFeO$_3$. This study focuses on thin Fe$_{0.81}$Ga$_{0.19}$ films of thickness 5, 10, 20 and 60 nm deposited by sputtering onto glass substrates. Magnetization reversal study reveals a well-defined symmetry with two principal directions independent of the thickness. The magnetic signature of this magnetic anisotropy decreases with increasing FeGa thickness due to an increase of the non-preferential polycrystalline arrangement, as revealed by transmission electron microscopy (TEM) observations. Thus when magnetic field is applied along these specific directions, magnetization reversal is mainly coherent for the thinnest sample as seen from the transverse magnetization cycles. Magnetostriction coefficient reaches 20 ppm for the 5 nm film and decreases for thicker samples, where polycrystalline part with non-preferential orientation prevails.

The proportionality constant is shown to be exactly as conjectured by Arbarello and Cornalba [J. Alg. Geom. 5 (1996) 705-749]. We also verify their conjectured formula for the leading coefficient of the polynomial expressing the Kontsevich cycles in terms of the Miller-Morita-Mumford classes.

description: Continuously monitoring the environment of a quantum many-body system reduces the entropy of (purifies) the reduced density matrix of the system, conditional on the outcomes of the measurements. We show that, for mixed initial states, a balanced competition between measurements and entangling interactions within the system can result in a dynamical purification phase transition between (i) a phase that locally purifies at a constant system-size-independent rate, and (ii) a "mixed" phase where the purification time diverges exponentially in the system size. The residual entropy density in the mixed phase implies the existence of a quantum error-protected subspace where quantum information is reliably encoded against the future non-unitary evolution of the system. We show that these codes are of potential relevance to fault-tolerant quantum computation as they are often highly degenerate and satisfy optimal tradeoffs between encoded information densities and error thresholds. In spatially local models in 1+1 dimensions, this phase transition for mixed initial states occurs concurrently with a recently identified class of entanglement phase transitions for pure initial states. The mutual information of an initially completely-mixed state in 1+1 dimensions grows sublinearly in time due to the formation of the error protected subspace. The purification transition studied here also generalizes to systems with long-range interactions, where conventional notions of entanglement transitions have to be reformulated. Purification dynamics is likely a more robust probe of the transition in experiments, where imperfections generically reduce entanglement and drive the system towards mixed states. We describe the motivations for studying this novel class of non-equilibrium quantum dynamics in the context of advanced quantum computing platforms and fault-tolerant quantum computation.

Validity of the Nonlinear Schrödinger Approximation for the Two-Dimensional Water Wave Problem With and Without Surface Tension in the Arc Length Formulation

description: We consider the two-dimensional water wave problem in an infinitely long canal of finite depth both with and without surface tension. In order to describe the evolution of the envelopes of small oscillating wave packet-like solutions to this problem the Nonlinear Schrödinger equation can be derived as a formal approximation equation. In recent years, the validity of this approximation has been proven by several authors for the case without surface tension. In this paper, we rigorously justify the Nonlinear Schrödinger approximation for the cases with and without surface tension by proving error estimates over a physically relevant timespan in the arc length formulation of the two-dimensional water wave problem. The error estimates are uniform with respect to the strength of the surface tension, as the height of the wave packet and the surface tension go to zero.

description: Rape, defined as the crime of forcing somebody to have sex, encompasses a spectrum of violent, destructive, and abusive behaviors, representing a blatant violation of an individual's self-worth, sense of security, and fundamental human dignity. This study delves into the intricate dimensions of rape, focusing on its various manifestations in today's interconnected global society.The literature on rape predominantly highlights its violent criminal aspects, revealing the multifaceted ways in which such incidents unfold within contemporary social networks. Throughout history, rape has been characterized by varying degrees of violence, often resulting in significant harm to the victim. Notably, the term 'rape' goes beyond its legal definition, encapsulating a broader violation of personal integrity and well-being.A pivotal aspect explored in this study is the marital dimension of rape, as identified by Riggs, Kilpatrick, and Reisnick (1992) in their examination of marital rape and aggravated assault. The research underscores the influence of marital relationships as a potent causal factor in rape incidents. Their findings reveal that women subjected to assault by their husbands are more likely to report recurring attacks, suggesting a pattern of violence within marital dynamics. Furthermore, victims of aggravated assault, as compared to rape victims, are reported to express a heightened fear for their lives during the assault, shedding light on the distinct characteristics and psychological impact associated with different forms of interpersonal violence. This research aims to contribute to a deeper understanding of the complexities surrounding rape incidents, emphasizing the need for nuanced perspectives that go beyond legal definitions. By unraveling the layers of violence and exploring the specific dynamics within marital relationships, the study seeks to inform interventions and support systems tailored to the diverse experiences of survivors. Ultimately, this exploration contributes to the ongoing discourse on addressing and preventing rape, promoting a comprehensive approach that considers the psychological, relational, and societal implications of this heinous crime

description: Positioned in the literature related to academic professional development, this study makes a contribution to the understanding of academics’ blended practices by exploring how various factors influence academics’ use of technology with face-to-face teaching. The primary research question addressed by the study is ‘Why do some academics tend to use technology together with their face-to-face teaching to achieve blended teaching strategies to support learning, while others do not?’ The study arises from a context in which a growing number of universities are investing considerable resources in blended learning, as an institutional strategy to respond to the pressures of uncertain economies, increasing globalisation, and the changing expectations of cohorts of digitally savvy students. However, the success of blended learning as an institutional strategy is firmly grounded in the widespread adoption of effective blended teaching practices, which has generally failed to happen. Currently, the adoption of effective blended teaching practices is limited to a minority of academics. The premise underlying this study is that understanding the factors shaping academics’ blended learning practices is fundamental to the provision of the professional support needed to facilitate the uptake of effective blended practices on a larger scale. Unfortunately, existing blended learning literature provides meagre insight into academics’ blended practices. This study stems from the urgent need to better understand academics’ blended teaching practices.

A conformal structure on $M$ corresponds to a section of $Z\to M$ and $\mathfrak{p}$ is metrisable by the metric $g$ if and only if $[g] : M \to Z$ is a pseudo-holomorphic curve with respect to $J_{\mathfrak{p}}$ and $\mathfrak{J}_{\mathfrak{p},dA_g}$.

description: Quantum applications are hybrid, i.e., they comprise quantum and classical programs, which must be orchestrated. Workflows are a proven solution for orchestrating heterogeneous programs while providing benefits, such as robustness or scalability. However, the orchestration using workflows can be inefficient for some quantum algorithms, requiring the execution of quantum and classical programs in a loop. Hybrid runtimes are offered to efficiently execute these algorithms. For this, the quantum and classical programs are combined in a single hybrid program, for which the execution is optimized. However, this leads to a conceptual gap between the modeling benefits of workflow technologies, e.g., modularization, reuse, and understandability, and the efficiency improvements when using hybrid runtimes. To close this gap, we introduce a method to model all tasks explicitly in the workflow model and analyze the workflow to detect parts of the workflow that can benefit from hybrid runtimes. Furthermore, corresponding hybrid programs are automatically generated based on the quantum and classical programs, and the workflow is rewritten to invoke them. To ease the live monitoring and later analysis of workflow executions, we integrate process views into our method and collect related provenance data. Thus, the user can visualize and monitor the workflow in the original and rewritten form within the workflow engine. The practical feasibility of our approach is validated by a prototypical implementation, a case study, and a runtime evaluation.

description: Circular-harmonic spectra are a compact representation of local image features in two dimensions. It is well known that the computational complexity of such transforms is greatly reduced when polar separability is exploited in steerable filter-banks. Further simplifications are possible when Cartesian separability is incorporated using the radial apodization (i.e. weight, window, or taper) described here, as a consequence of the Laguerre/Hermite correspondence over polar/Cartesian coordinates. The chosen form also mitigates undesirable discretization artefacts due to angular aliasing. The possible utility of circular-harmonic spectra for the description of simple features is illustrated using real data from an airborne electro-optic sensor. The spectrum is deployed in a test-statistic to detect and characterize corners of arbitrary angle and orientation (i.e. wedges). The test-statistic considers uncertainty due to finite sampling and clutter/noise.

Within a reasonnable assumption concerning the nucleation and coalescence of shocks, we find in particular that the `left' tail of the distribution decays as an inverse square power, which is compatible with numerical data. Our results are compared to those of various recent approaches: instantons, operator product expansion, replicas.

description: Classically, endemic infectious diseases are expected to display relatively stable, predictable infection dynamics. Accordingly, basic disease models such as the susceptible-infected-recovered-susceptible model display stable endemic states or recurrent seasonal waves. However, if the human population reacts to high infection numbers by mitigating the spread of the disease, then this delayed behavioral feedback loop can generate infection waves itself, driven by periodic mitigation and subsequent relaxation. We show that such behavioral reactions, together with a seasonal effect of comparable impact, can cause complex and unpredictable infection dynamics, including Arnold tongues, coexisting attractors, and chaos. Importantly, these arise in epidemiologically relevant parameter regions where the costs associated to infections and mitigation are jointly minimized. By comparing our model to data, we find signs that COVID-19 was mitigated in a way that favored complex infection dynamics. Our results challenge the intuition that endemic disease dynamics necessarily implies predictability and seasonal waves and show the emergence of complex infection dynamics when humans optimize their reaction to increasing infection numbers.
Is it possible to reconcile extragalactic IMF variations with a universal Milky Way IMF?

description: One of the most robust observations of the stellar initial mass function (IMF) is its near-universality in the Milky Way and neighboring galaxies. But recent observations of early-type galaxies can be interpreted to imply a bottom-heavy IMF, while others of ultra-faint dwarfs could imply a top-heavy IMF. This would impose powerful constraints on star formation models. We explore what sort of cloud-scale IMF models could possibly satisfy these constraints. We utilize simulated galaxies which reproduce (broadly) the observed galaxy properties, while they also provide the detailed star formation history and properties of each progenitor star-forming cloud. We then consider generic models where the characteristic mass of the IMF is some arbitrary power-law function of progenitor cloud properties, along with well-known literature IMF models, which scale with Jeans mass, turbulent Bonnor-Ebert mass, temperature, the opacity limit, metallicity, or the protostellar heating mass. We show that no IMF models currently in the literature - nor any model where the turnover mass is an arbitrary power-law function of a combination of cloud temperature/density/size/metallicity/velocity dispersion/magnetic field - can reproduce the claimed IMF variation in ellipticals or dwarfs without severely violating observational constraints in the Milky Way. Specifically, they predict too much variation in the extreme environments of the Galaxy, compared to that observed. Either the IMF varies in a more complicated manner, or alternative interpretations of the extragalactic observations must be explored.

Experimenting on the Poor: The Politics of Social Policy Evaluations in Brazil and Mexico

description: In the 1990s, Brazil and Mexico were pioneers in the implementation of conditional cash transfer programs (CCTs), which since have benefitted an estimated one billion poor families around the world. However, the initial evaluation strategies pursued by each state were different: Mexican officials partnered with US economists to implement an RCT evaluation, while Brazilians used a combination of statistical simulations and qualitative studies and aimed to secure the generation of policy knowledge to domestic experts. Based on eighteen months of participant observation in Mexico City and Brasília, 100 interviews with political and academic elites, content analysis of 400 policy documents, and historical-process tracing methods, this dissertation explains why these two similar countries, implementing the same policy, took different routes to assess the merits of CCTs, and what unintended consequences followed from these choices. I demonstrate that a key factor to achieve the legitimacy and political viability of CCTs is the knowledge regimes that states create to implement and evaluate these programs. The dissertation shows that while knowledge regimes tend to be understood as technical or apolitical machineries, they are inherently shaped by the politics of legitimation of CCTs and they produce unanticipated consequences for the ways that states combat poverty in the long-run. Only by taking into consideration the role that knowledge production plays in securing the political viability of CCTs, I argue, we can assess the politics and consequences of these programs, and how they relate to poor families on the ground.

description: The tree-independence number tree-$α$, first defined and studied by Dallard, Milanič and Štorgel, is a variant of treewidth tailored to solving the maximum independent set problem.
 Over a series of papers, Abrishami et al. developed the so-called central bag method to study induced obstructions to bounded treewidth. Among others, they showed that, in a certain superclass $\mathcal C$ of (even hole, diamond, pyramid)-free graphs, treewidth is bounded by a function of the clique number. In this paper, we relax the bounded clique number assumption, and show that $\mathcal C$ has bounded tree-$α$. Via existing results, this yields a polynomial time algorithm for the maximum independent set problem in this class. Our result also corroborates, for this class of graphs, a conjecture of Dallard, Milanič and Štorgel that in a hereditary graph class, tree-$α$ is bounded if and only if the treewidth is bounded by a function of the clique number.

description: Young people learn about and interact with health and fitness through multiple pedagogical sites, including after-school programs, print and social media, fitness centers, families and peers. As such, the purpose of this dissertation was to explore the ways in which Black and Latinx youth interacted with health and fitness in an urban after-school context. To do so, a visual ethnographic approach was used over 18-months, working with youth in different ways over that time period. Data generation methods included participant observation (field notes, informal conversations), semi-structured interviews, participant-driven visual diaries and a scrapbooking project. Data analysis involved various inquiry techniques such as thinking through (affect) theory, Maggie MacLure’s interpretation of coding, and collage as analysis. Affect theory, from a new materialist and feminist lens, framed this dissertation. Using these theoretical and methodological approaches, I share three manuscripts that highlight affective flows produced at different points in the dissertation research. These involve (1) a focus on beginning to experiment with visual methods and five youth; (2) a pedagogical encounter between four youth, two fitness professionals and myself; and (3) a collage-as-analysis that held potential to de-territorialize research practices as usual. Through these manuscripts, I argue that this dissertation begins to create (non-traditional) ways to reimagine health and fitness so that all bodies (Black/Latinx youth and fitness professionals, White woman researcher, images, texts, words) come to matter for research and pedagogical practices with high school-aged youth in an urban after-school context.
Towards Data Auctions with Externalities

description: The design of data markets has gained importance as firms increasingly use machine learning models fueled by externally acquired training data. A key consideration is the externalities firms face when data, though inherently freely replicable, is allocated to competing firms. In this setting, we demonstrate that a data seller's optimal revenue increases as firms can pay to prevent allocations to others. To do so, we first reduce the combinatorial problem of allocating and pricing multiple datasets to the auction of a single digital good by modeling utility for data through the increase in prediction accuracy it provides. We then derive welfare and revenue maximizing mechanisms, highlighting how the form of firms' private information - whether the externalities one exerts on others is known, or vice-versa - affects the resulting structures. In all cases, under appropriate assumptions, the optimal allocation rule is a single threshold per firm, where either all data is allocated or none is.
A primal-dual dynamical approach to structured convex minimization problems

description: In this paper we propose a primal-dual dynamical approach to the minimization of a structured convex function consisting of a smooth term, a nonsmooth term, and the composition of another nonsmooth term with a linear continuous operator. In this scope we introduce a dynamical system for which we prove that its trajectories asymptotically converge to a saddle point of the Lagrangian of the underlying convex minimization problem as time tends to infinity. In addition, we provide rates for both the violation of the feasibility condition by the ergodic trajectories and the convergence of the objective function along these ergodic trajectories to its minimal value. Explicit time discretization of the dynamical system results in a numerical algorithm which is a combination of the linearized proximal method of multipliers and the proximal ADMM algorithm.

description: In this paper, for the 3-D Navier-Stokes-Boussinesq system with horizontal dissipation, where there is no smoothing effect on the vertical derivatives, we prove a uniqueness result of solutions $ (u,ρ)\in L^{\infty}_T\big( H^{0,s}\times H^{0,1-s}\big)$ with $ (\nabla_h u,\nabla_hρ)\in L^{2}_T\big( H^{0,s}\times H^{0,1-s}\big)$ and $s\in [1/2,1]$. As a consequence, we improve the conditions stated in the paper \cite{Miao} in order to obtain a global well-posedness result in the case of axisymmetric initial data.

description: The kernel method is an essential tool for the study of generating series of walks in the quarter plane. This method involves equating to zero a certain polynomial, the kernel polynomial, and using properties of the curve, the kernel curve, this defines. In the present paper, we investigate the basic properties of the kernel curve (irreducibility, singularities, genus, uniformization, etc).
