description: Graph processing has become an important part of various areas of computing, including machine learning, medical applications, social network analysis, computational sciences, and others. A growing amount of the associated graph processing workloads are dynamic, with millions of edges added or removed per second. Graph streaming frameworks are specifically crafted to enable the processing of such highly dynamic workloads. Recent years have seen the development of many such frameworks. However, they differ in their general architectures (with key details such as the support for the concurrent execution of graph updates and queries, or the incorporated graph data organization), the types of updates and workloads allowed, and many others. To facilitate the understanding of this growing field, we provide the first analysis and taxonomy of dynamic and streaming graph processing. We focus on identifying the fundamental system designs and on understanding their support for concurrency, and for different graph updates as well as analytics workloads. We also crystallize the meaning of different concepts associated with streaming graph processing, such as dynamic, temporal, online, and time-evolving graphs, edge-centric processing, models for the maintenance of updates, and graph databases. Moreover, we provide a bridge with the very rich landscape of graph streaming theory by giving a broad overview of recent theoretical related advances, and by discussing which graph streaming models and settings could be helpful in developing more powerful streaming frameworks and designs. We also outline graph streaming workloads and research challenges.

Werk je met digitale informatieobjecten, dan ontkom je er niet aan ook meer te weten over de dragers van de informatie, namelijk de bestandsformaten. Bestandsformaten vragen om beleid van de instelling: welke garanties wil of kan de instelling afgeven ten aanzien van duurzaam preserveren. En hoe communiceert de instelling daarover met aanbieders (of gebruikers) van het materiaal. Het Netwerk Digitaal Erfgoed (NDE) werkt aan een online hulpmiddel om instellingen te helpen beleid te formuleren rond bestandsformaten. Dit online hulpmiddel wordt de Wegwijzer Voorkeursformaten. De Wegwijzer bestaat uit twee onderdelen: een deel dat via uitleg en voorbeelden instellingen handreikingen wil bieden voor opstellen van beleid, en een deel dat dient als register met informatie over bestandsformaten. De Wegwijzer wordt beheerd door een Expertisegroep Voorkeursformaten die bestaande kennis in nationaal verband bundelt, deelt en verder ontwikkelt.

description: This article is a presentation of specific recent results describing scaling limits of individual-based models. Thanks to them, we wish to relate the time-scales typical of demographic dynamics and natural selection to the parameters of the individual-based models. Although these results are by no means exhaustive, both on the mathematical and the biological level, they complement each other. Indeed, they provide a viewpoint for many classical time-scales. Namely, they encompass the timescale typical of the life-expectancy of a single individual, the longer one wherein a population can be characterized through its demographic dynamics, and at least four interconnected ones wherein selection occurs. The limiting behavior is generally deterministic. Yet, since there are selective effects on randomness in the history of lineages, probability theory is shown to be a key factor in understanding the results. Besides, randomness can be maintained in the limiting dynamics, for instance to model rare mutations fixing in the population.

description: We have shown in previous work that the rigorous equivalence of the Schrödinger and Heisenberg pictures requires that one uses Born-Jordan quantization in place of Weyl quantization. It also turns out that the so-called Dahl-Springborg angular momentum dilemma disappears if one uses Born--Jordan quantization. These two facts strongly suggest that the latter is the only true quantization procedure, and this leads to a redefinition of phase space quantum mechanics, where the usual Wigner distribution has to be replaced with a new distribution.

description: The mass of the dark matter halo of the Milky Way can be estimated by fitting analytical models to the phase-space distribution of dynamical tracers. We test this approach using realistic mock stellar halos constructed from the Aquarius N-body simulations of dark matter halos in the $Λ$CDM cosmology. We extend the standard treatment to include a Navarro-Frenk-White (NFW) potential and use a maximum likelihood method to recover the parameters describing the simulated halos from the positions and velocities of their mock halo stars. We find that the estimate of halo mass is highly correlated with the estimate of halo concentration. The best-fit halo masses within the virial radius, $R_{200}$, are biased, ranging from a 40\% underestimate to a 5\% overestimate in the best case (when the tangential velocities of the tracers are included). There are several sources of bias. Deviations from dynamical equilibrium can potentially cause significant bias; deviations from spherical symmetry are relatively less important. Fits to stars at different galactocentric radii can give different mass estimates. By contrast, the model gives good constraints on the mass within the half-mass radius of tracers even when restricted to tracers within 60kpc. The recovered velocity anisotropies of tracers, $β$, are biased systematically, but this does not affect other parameters if tangential velocity data are used as constraints.

description: A minimal observable length is a common feature of theories that aim to merge quantum physics and gravity. Quantum mechanically, this concept is associated to a nonzero minimal uncertainty in position measurements, which is encoded in deformed commutation relations. In spite of increasing theoretical interest, the subject suffers from the complete lack of dedicated experiments and bounds to the deformation parameters are roughly extrapolated from indirect measurements. As recently proposed, low-energy mechanical oscillators could allow to reveal the effect of a modified commutator. Here we analyze the free evolution of high quality factor micro- and nano-oscillators, spanning a wide range of masses around the Planck mass $m_{\mathrm{P}}$ (${\approx 22\,μ\mathrm{g}}$), and compare it with a model of deformed dynamics. Previous limits to the parameters quantifying the commutator deformation are substantially lowered.

The wavefront of the incident light was systematically controlled using a spatial light modulator in order to overcome multiple light-scattering in a mouse skull layer and to focus light on the target cells. We demonstrate that illumination with shaped waves enables spatiotemporal regulation of intracellular Ca2+ level at the individual-cell level.

description: Background: Results from trials and nonexperimental studies are often directly compared, with little attention paid to differences between study populations. When target and trial population data are available, accounting for these differences through transporting trial results to target populations of interest provides useful perspective. We aimed to compare two-year risk differences (RDs) for ischemic stroke, mortality, and gastrointestinal bleeding in older adults with atrial fibrillation initiating dabigatran and warfarin when using trial transport methods versus nonexperimental methods. Methods: We identified Medicare beneficiaries who initiated warfarin or dabigatran from a 20% nationwide sample. To transport treatment effects observed in the randomized evaluation of long-term anticoagulation trial, we applied inverse odds weights to standardize estimates to two Medicare target populations of interest, initiators of: (1) dabigatran and (2) warfarin. Separately, we conducted a nonexperimental study in the Medicare populations using standardized morbidity ratio weighting to control measured confounding. Results: Comparing dabigatran to warfarin, estimated two-year RDs for ischemic stroke were similar with trial transport and nonexperimental methods. However, two-year mortality RDs were closer to the null when using trial transport versus nonexperimental methods for the dabigatran target population (transported RD: -0.57%; nonexperimental RD: -1.9%). Estimated gastrointestinal bleeding RDs from trial transport (dabigatran initiator RD: 1.8%; warfarin initiator RD: 1.9%) appeared more harmful than nonexperimental results (dabigatran initiator RD: 0.14%; warfarin initiator RD: 0.57%). Conclusions: Differences in study populations can and should be considered quantitatively to ensure results are relevant to populations of interest, particularly when comparing trial with nonexperimental findings.

description: We study critical Fermi surfaces in generic dimensions arising from coupling finite-density fermions with transverse gauge fields, by applying the dimensional regularization scheme developed previously [Phys. Rev. B 92, 035141 (2015)]. We consider the cases of $U(1)$ and $U(1)\times U(1)$ transverse gauge couplings, and extract the nature of the renormalization group (RG) flow fixed points as well as the critical scalings. Our analysis allows us to treat a critical Fermi surface of a generic dimension $m$ perturbatively in an expansion parameter $ε=\left (2-m \right ) /\left (m+1 \right).$ One of our key results is that although the two-loop corrections do not alter the existence of an RG flow fixed line for certain $U(1)\times U(1)$ theories, which was identified earlier for $m=1$ at one-loop order, the third-order diagrams do. However, this fixed line feature is also obtained for $m>1$, where the answer is one-loop exact due to UV/IR mixing.
description: follows the formalism of arXiv:1407.0033; have corrected a typographical error in the appendix, which led to an incorrect result for the vertex correction for the $m=1$ case; although the correction changes the RG flow equations in the main text, it does not affect our main results and conclusions; the erratum has been published in Phys.

description: Big data are data on a massive scale in terms of volume, intensity, and complexity that exceed the capacity of standard software tools. They present opportunities as well as challenges to statisticians. The role of computational statisticians in scientific discovery from big data analyses has been under-recognized even by peer statisticians. This article reviews recent methodological and software developments in statistics that address the big data challenges. Methodologies are grouped into three classes: subsampling-based, divide and conquer, and sequential updating for stream data. Software review focuses on the open source R and R packages, covering recent tools that help break the barriers of computer memory and computing power. Some of the tools are illustrated in a case study with a logistic regression for the chance of airline delay.

description: The chemical industry represents ca. 7% of the global GDP and 40% of its immense energy footprint stems from the separation/purification processes of commodity chemicals, particularly downstream processing of hydrocarbons. Of critical importance is the separation of C6 cyclic hydrocarbons benzene (C6H6) and cyclohexane (C6H12). Supplanting thermally driven distillation protocols such as azeotropic and extractive distillation methods by recyclable adsorbents, such as metal-organic framework (MOF) physisorbents, holds great promise for the reduction of this energy footprint. Whilst MOFs have come of age as physisorbents, they have been studied as benzene or cyclohexane selective adsorbents only rarely. Thanks to their amenability to crystal engineering, intensive research efforts have enabled metal-organic chemists to offer tunable coordination nanospaces in MOF sorbents in an adsorbate-specific manner, including aromatic benzene or aliphatic cyclohexane molecules. Despite the ever-expanding library of MOFs that often features families or isoreticular platforms of high surface-area materials with electron-rich or electron-deficient local pore environments, this research topic is underexplored and represents a niche area with a high upside potential. This review captures the progress made in MOF adsorbents to accomplish adsorption selectivity guided separation of the foregoing pair of C6 azeotropic hydrocarbons, which is crucial to the production of high-grade cyclohexane and benzene -important feedstock chemicals for further conversion into more useable commodity products, or as liquid organic hydrogen carriers. We also critically interrogate these examples to understand key structural and compositional approaches in order to efficiently design MOFs to extract benchmark selectivities and consequent high separation performances.

description: Holomorphic renormalization plays an important role in complex polynomial dynamics. We consider certain conditions guaranteeing that a polynomial which does not admit a polynomial-like connected Julia set still admits an invariant continuum on which it is topologically conjugate to a lower degree polynomial. This invariant continuum may contain extra critical points of the original polynomial that are not visible in the dynamical plane of the conjugate polynomial. Thus, we extend the notions of holomorphic renormalization and polynomial-like maps and describe a setup where new generalized versions of these notions are applicable and yield useful topological conjugacies.

description: Herein, AlN growth by metalorganic vapor‐phase epitaxy on hole‐type nanopatterned sapphire substrates is investigated. Cracking occurs for an unexpectedly thin‐layer thickness, which is associated to altered nucleation conditions caused by the sapphire pattern. To overcome the obstacle of cracking and at the same time to decrease the threading dislocation density by an order of magnitude, high‐temperature annealing (HTA) of a 300 nm‐thick AlN starting layer is successfully introduced. By this method, 800 nm‐thick, fully coalesced and crack‐free AlN is grown on 2 in. nanopatterned sapphire wafers. The usability of such templates as basis for UVC light‐emitting diodes (LEDs) is furthermore proved by subsequent growth of an UVC‐LED heterostructure with single peak emission at 265 nm. Prerequisites for the enhancement of the light extraction efficiency by hole‐type nanopatterned sapphire substrates are discussed.

description: Constructivist epistemology posits that all truths are knowable. One might ask to what extent constructivism is compatible with naturalized epistemology and knowledge obtained from inference-making using successful scientific theories. If quantum theory correctly describes the structure of the physical world, and if quantum theoretic inferences about which measurement outcomes will be observed with unit probability count as knowledge, we demonstrate that constructivism cannot be upheld. Our derivation is compatible with both intuitionistic and quantum propositional logic. This result is implied by the Frauchiger-Renner theorem, though it is of independent importance as well.

title: Developing a data analysis tool to understand phenotypic heterogeneity from live imaging of 3-Dimensional tumour cell cultures
Creators: name: Freckmann, Eva C.
Publisher: name: University of Glasgow
Year: 2022

description: Intra-tumour heterogeneity creates a major challenge in cancer treatment; while some cells in the tumour population are responsive to therapy, others may be resistant. This variable response to treatment leads to acquired treatment-resistance in the cell population, and eventual relapse for the patient. Single cell profiling by genetic, proteomic and imaging methods has expanded the ability to identify programmes that regulate distinct cell states. The 3-dimensional (3D) culture of cells or tissue fragments provides a system to study how such states contribute to multicellular morphogenesis. Due to a lack of tools for the detection and interrogation of heterogeneity, whether cells cultured in 3D exhibit a singular phenotype or whether multiple biologically distinct phenotypes arise in parallel remains an open question. In this thesis I present a computational method I developed for the analysis of label-free multi-day time-lapse imaging to identify heterogeneous states in 3D culture and how these give rise to distinct temporal behaviours. With the help of collaborators I use this to identify the temporal landscape of states of cancer cell lines varying in metastatic potential and drug resistance, using this information to identify drug combinations that inhibit such heterogeneity. This approach is therefore an important companion tool to single-cell technologies by facilitating real-time identification via live-imaging of distinct temporal phenotypes that occur in parallel in 3D culture.
Construction of blow-up manifolds to the equivariant self-dual Chern-Simons-Schrödinger equation

description: We consider the self-dual Chern-Simons-Schrödinger equation (CSS) under equivariance symmetry. Among others, (CSS) has a static solution $Q$ and pseudoconformal symmetry. We study the conditional stability of pseudoconformal blow-up solutions $u$ such that \[ u(t,r)-\frac{e^{iγ_{\ast}}}{T-t}Q\Big(\frac{r}{T-t}\Big)\to u^{\ast}\quad\text{as }t\to T^{-}. \] When the equivariance index $m\geq1$, we construct a codimension one blow-up manifold, i.e. a codimension one set of initial data yielding pseudoconformal blow-up solutions. Moreover, when $m\geq3$, we establish the Lipschitz regularity of the constructed blow-up manifold (the conditional stability). This is a forward construction of blow-up solutions, as opposed to authors' previous work [25] (arXiv:1909.01055), which is a backward construction of blow-up solutions with prescribed asymptotic profiles. In view of the instability result of [25], the codimension one condition is expected to be optimal. We perform the modulation analysis with a robust energy method developed by Merle, Raphaël, Rodnianski, and others. One of our crucial inputs is a remarkable conjugation identity, which enables the method of supersymmetric conjugates as like Schrödinger maps and wave maps. It suggests how we define adapted derivatives. More interestingly, it shows a deep connection with the Schrödinger maps at the linearized level and allows us to find a repulsivity structure. The nonlocal nonlinearities become obstacles in many places. For instance, we need to capture non-perturbative contributions from the nonlocal nonlinearities and absorb them into phase corrections in a spirit of [25]. More importantly, we need to take a nonlinear pathway to construct modified profiles. This is suggested from [25] and becomes available thanks to the self-duality. From this, we also recognize the stable modes and unstable modes.

description: Objective: The aim of this study was to evaluate HIV testing yield under several candidate strategies for outreach testing at venues (i.e. places where people socialize and meet new sex partners) in East Africa cross-border areas. Design: Population-based cross-sectional biobehavioural survey of people who had not been previously diagnosed with HIV found in venues. Methods: We identified participants who would have been tested for HIV under each of 10 hypothetical outreach testing strategies and calculated the proportion who would have newly tested positive for HIV under each strategy. On the basis of this proportion, we calculated the 'number needed to test' (NNT) to identify one new case of HIV under each strategy. All estimates were obtained by applying survey sampling weights to account for the complex sampling design. Results: If testing was performed at a random sample of venues, 35 people would need to be tested to identify one new case of HIV, but higher yield could be found by limiting testing to venues with specific characteristics. Strategies focusing on women had higher testing yield. Testing women employed by venues would result in highest yield of all strategies examined (NNT=15), while testing men under age 24 would result in the lowest yield (NNT=99). Conclusion: Quantitatively evaluating HIV testing strategies prior to implementation using survey data presents a new opportunity to refine and prioritize outreach testing strategies for the people and places most likely to result in high HIV testing yield

description: Included under the single parameter cosine family, the D-dimensional logarithmic (dlog) grid is a generalization of the simple logarithmic grid that emulates the evolution of animal populations. In turn, these grids are $\mathbf{X}(K, H)$ defined by
$$
\int_{X_i}^{X_{i+1}} \int_{X_j}^{X_{j+1}} \int_{X_k}^{X_{k+1}} \cdots \int_{X_D}^{X_{D+1}} f\left[\left(X_i^{d_{i+1}+1}\right) \cdot \cdots \cdot\left(X^{d_{1+1}}\right)\right] \mathrm{d} X_i \mathrm{~d} X_j \mathrm{~d} X_k \cdots \mathrm{d} X_D=f\left(X^{p_{K+1}}\right) \cdot f\left(X^{5_{K+1}}\right)
$$
where $\mathbf{X}(K, H)$ denotes the uniform grid between arbitrary boundaries $X_i=$ $H_K^{d_i}$ where $p_{K+1}$ is the prime root of $K+1$, measured in Kelvins, the logarithmic factor generated between prime $5_{K+1}$ and $5_{K+2}$ plays a special role in the corner hierarchy, and $d_i$ denotes the number of logarithmic steps towards $p_{K+1}$ for some integer $i$. To enable full localization of all cells, optimal construction of $X_i$ for arbitrary $H_i$ is possible due to Ricky's Theorem.

description: The paradigm of variational quantum classifiers (VQCs) encodes \textit{classical information} as quantum states, followed by quantum processing and then measurements to generate classical predictions. VQCs are promising candidates for efficient utilization of a near-term quantum device: classifiers involving $M$-dimensional datasets can be implemented with only $\lceil \log_2 M \rceil$ qubits by using an amplitude encoding. A general framework for designing and training VQCs, however, has not been proposed, and a fundamental understanding of its power and analytical relationships with classical classifiers are not well understood. An encouraging specific embodiment of VQCs, quantum circuit learning (QCL), utilizes an ansatz: it expresses the quantum evolution operator as a circuit with a predetermined topology and parametrized gates; training involves learning the gate parameters through optimization. In this letter, we first address the open questions about VQCs and then show that they, including QCL, fit inside the well-known kernel method. Based on such correspondence, we devise a design framework of efficient ansatz-independent VQCs, which we call the unitary kernel method (UKM): it directly optimizes the unitary evolution operator in a VQC. Thus, we show that the performance of QCL is bounded from above by the UKM. Next, we propose a variational circuit realization (VCR) for designing efficient quantum circuits for a given unitary operator. By combining the UKM with the VCR, we establish an efficient framework for constructing high-performing circuits. We finally benchmark the relatively superior performance of the UKM and the VCR via extensive numerical simulations on multiple datasets.

description: This study investigated the sexual behavior of young people in Etche Local Government Area (LGA), Rivers State, where concerns regarding risky sexual practices among youth have grown due to a rise in sexual activity. The research adopted a cross-sectional descriptive survey design, with a population of 351,200 young people in Etche, from which a sample of 400 youths was selected through a multi-stage sampling procedure. Data collection was facilitated using a semi-structured questionnaire, which was tested for reliability with a coefficient of 0.71. Statistical analysis was performed using SPSS V-25, employing mean, t-test, and Pearson Correlation at a 0.05 significance level. The results revealed that common sexual behaviors among youths included spending time with the opposite sex (𝑋̅ = 2.95±1.23), having a boyfriend or girlfriend (𝑋̅ = 2.77±0.23), and being attracted to revealing clothing (𝑋̅ = 2.63±1.33). The study also showed a significant difference between male and female perceptions of sexual behavior in Etche LGA, with a t-cal value of 2.22 and a p-value of 0.02. The findings indicated that young people in Etche exhibited risky sexual behaviors, which increased their vulnerability to sexually transmitted infections (STIs) and other associated health risks. Consequently, the study recommends that youth-friendly organizations develop targeted intervention programs to guide young people toward healthier sexual practices and reduce the incidence of STIs
Hidden imputations and the kaplan-meier estimator

description: The Kaplan-Meier (KM) estimator of the survival function imputes event times for right-censored and left-truncated observations, but these imputations are hidden and therefore sometimes unrecognized by applied health scientists. Using a simple example data set and the redistribution algorithm, we illustrate how imputations are made by the KM estimator. We also discuss the assumptions necessary for valid analyses of survival data. Illustrating imputations hidden by the KM estimator helps to clarify these assumptions and therefore may reduce inappropriate inferences.

Reduction of the Twisted Bilayer Graphene Chiral Hamiltonian into a $2\times2$ matrix operator and physical origin of flat-bands at magic angles

description: The chiral Hamiltonian for twisted graphene bilayers is written as a $2\times2$ matrix operator by a renormalization of the Hamiltonian that takes into account the particle-hole symmetry. This results in an effective Hamiltonian with an average field plus and effective non-Abelian gauge potential. The action of the proposed renormalization maps the zero-mode region into the ground state. Modes near zero energy have an antibonding nature in a triangular lattice. This leads to a phase-frustration effect associated with massive degeneration, and makes flat-bands modes similar to confined modes observed in other bipartite lattices. Suprisingly, the proposed Hamiltonian renormalization suggests that flat-bands at magic angles are akin to floppy-mode bands in flexible crystals or glasses, making an unexpected connection between rigidity topological theory and magic angle twisted two-dimensional heterostructures physics.
The South’s ‘negligible minorities’ : the influence of whiteness on the Southern construction of race, gender and class in Ellen Glasgow’s novels

description: Race remains one of the least discussed topics among Glasgow’s critics and no consensus about her racial politics has been reached. Some critics argue that race is almost absent from Glasgow’s agenda of social criticism compared to her more vocal feminist views. Other critics accuse Glasgow of outright racism, citing what they see as a condescending and racist characterisation of African Americans in her works. A third view defends the existence of a valid impetus against racism in Glasgow’s works but refers to her attitude as ambiguous. While these researchers aid understanding of Glasgow’s fiction, their critique is tied into the more conventional approach to race studies that concentrates on the effect of racism rather than the role of the racist subject.This study attempts to redress the limitations of the existing studies of Glasgow’s works by incorporating her identity as a white southern woman and the identity of her white characters in the reading of race in her novels. My reading attempts to tease out the subtle or unconscious ideologies and practices of white identity that originated, transformed, and most importantly, naturalised the construct of race, gender, and class in the southern context. Thus, the approach taken is to focus on Glasgow’s characters as identities shaped by a broad white culture that in itself was changing, affecting and effected by the South’s historical, political, and social contexts. My approach is to embed close textual analysis of the novels within whiteness theories and within historical and social studies to render visible the multiple and changing origins of white identity. Focusing on six key novels: The Battle-Ground (1902), The Deliverance (1904), The Voice of the People (1900), One Man in His Time (1922), Vein of Iron (1935), and In This Our Life (1941), this research aims to analyse how Glasgow’s aristocratic characters serve to critique white masculinity as a sustainable identity; how her poor white characters offer strategies to whiteness that challenge class exclusivity; and how her female characters adopt alternative approaches for self-realisation that negotiate with gender determinism.
