description: Face super-resolution is a technology that transforms a low-resolution face image into the corresponding high-resolution one. In this paper, we build a novel parsing map guided face super-resolution network which extracts the face prior (i.e., parsing map) directly from low-resolution face image for the following utilization. To exploit the extracted prior fully, a parsing map attention fusion block is carefully designed, which can not only effectively explore the information of parsing map, but also combines powerful attention mechanism. Moreover, in light of that high-resolution features contain more precise spatial information while low-resolution features provide strong contextual information, we hope to maintain and utilize these complementary information. To achieve this goal, we develop a multi-scale refine block to maintain spatial and contextual information and take advantage of multi-scale features to refine the feature representations. Experimental results demonstrate that our method outperforms the state-of-the-arts in terms of quantitative metrics and visual quality.

description: The threat of (HTs) and their detection is a widely studied field. While the effort for inserting a Trojan into an (ASIC) can be considered relatively high, especially when trusting the chip manufacturer, programmable hardware is vulnerable to Trojan insertion even after the product has been shipped or during usage. At the same time, detecting dormant HTs with small or zero-overhead triggers and payloads on these platforms is still a challenging task, as the Trojan might not get activated during the chip verification using logical testing or physical measurements. In this work, we present a novel Trojan detection approach based on a technique known from (IC) failure analysis, capable of detecting virtually all classes of dormant Trojans. Using (LLSI), we show how supply voltage modulations can awaken inactive Trojans, making them detectable using laser voltage imaging techniques. Therefore, our technique does not require triggering the Trojan. To support our claims, we present three case studies on 28 nm and 20 nm SRAM- and flash-based (FPGAs). We demonstrate how to detect with high confidence small changes in sequential and combinatorial logic as well as in the routing configuration of FPGAs in a non-invasive manner. Finally, we discuss the practical applicability of our approach on dormant analog Trojans in ASICs.

description: Magnetic fields on small scales are ubiquitous in the universe. Though they can often be observed in detail, their generation mechanisms are not fully understood. One possibility is the so-called small-scale dynamo (SSD). Prevailing numerical evidence, however, appears to indicate that an SSD is unlikely to exist at very low magnetic Prandtl numbers ($Pr_M$) such as are present in the Sun and other cool stars. We have performed high-resolution simulations of isothermal forced turbulence employing the lowest $Pr_M$ values so far achieved. Contrary to earlier findings, the SSD turns out to be not only possible for $Pr_M$ down to 0.0031, but even becomes increasingly easier to excite for $Pr_M$ below $\simeq\,$0.05. We relate this behaviour to the known hydrodynamic phenomenon referred to as the bottleneck effect. Extrapolating our results to solar values of $Pr_M$ indicates that an SSD would be possible under such conditions.

description: We address low-density two-dimensional circular quantum dots with spin-restricted Kohn-Sham density functional theory. By using an exchange-correlation functional that encodes the effects of the strongly-correlated regime (and that becomes exact in the limit of infinite correlation), we are able to reproduce characteristic phenomena such as the formation of ring structures in the electronic total density, preserving the fundamental circular symmetry of the system. The observation of this and other well-known effects in Wigner-localized quantum dots such as the flattening of the addition energy spectra, has until now only been within the scope of other, numerically more demanding theoretical approaches

title: Numerical investigation of fracture of polycrystalline ice under dynamic loading
Creators: name: Gribanov, Igor
Publisher: name: Memorial University of Newfoundland
Year: 2020

description: Cohesive zone model is a promising technique for simulating fracture processes in brittle ice.
 In this work it is applied to investigate the fracture behavior of polycrystalline cylindrical samples
 under uniaxial loading conditions, four-point beam bending, and L-shaped beam bending.
 In each case, the simulation results are compared with the corresponding experimental data
 that was collected by other researchers. The model is based on the implicit finite element
 method combined with Park-Paulino-Roesler formulation for cohesive potential and includes
 an adaptive time stepping scheme, which takes into account the rate of damage and failure
 of cohesive zones. The benefit of the implicit scheme is that it allows larger time steps than
 explicit integration. Material properties and model parameters are calibrated using available
 experimental data for freshwater ice and sea ice samples.
 For polycrystalline ice, granular geometry is generated and cohesive zones are inserted between
 grains. Simulations are performed for samples with different grain sizes, and the resulting
 stress–strain and damage accumulation curves are recorded. Investigation of the dependency
 between the grain size and fracture strength shows a strengthening effect that is
 consistent with experimental results.
 The proposed framework is also applied to simulate the dynamic fracture processes in Lshaped
 beams of sea ice, in which case the cohesive zones are inserted between the elements
 of the mesh. Evolution of the stress distribution on the surface of the beam is modeled for
 the duration of the loading process, showing how it changes with progressive accumulation of
 damage in the material, as well as the development of cracks. An analytical formula is derived
 for estimating the breaking force based on the dimensions of the beam and the ice strength.
 Experimental data obtained from the 2014-2016 tests are re-evaluated with the aid of this new
 analysis.
 The computation is implemented efficiently with GPU acceleration, allowing to handle geometries
 with higher resolution than would be possible otherwise. Several technical contributions
 are described in detail including GPU-accelerated FEM implementation, an efficient way of
 creation of sparse matrix structure, and comparison of different unloading/reloading relations
 when using an implicit integration scheme. A mechanism for collision response allows modeling
 the interaction of fragmented material. To evaluate the collision forces, an algorithm for
 computing first and second point-triangle distance derivatives was developed. The source code
 is made available as open-source.

description: Bhargava introduced a generalization of the factorial function to extend classical results in integers to Dedekind rings and unify them. We study the Bhargava factorial of the images of polynomial maps from an analytic perspective. We first give the $\mathfrak p$-adic closures of the images of polynomial maps, which is the key to compute $\mathfrak p$-adic part of the Bhargava factorial. Then, as a special case, we give the Stirling formula for the image of quadratic polynomials with integer coefficients.

description: We experimentally study the full counting statistics of few-body Rydberg aggregates excited from a quasi-one-dimensional Rydberg gas. We measure asymmetric excitation spectra and increased second and third order statistical moments of the Rydberg number distribution, from which we determine the average aggregate size. Direct comparisons with numerical simulations reveal the presence of liquid-like spatial correlations, and indicate sequential growth of the aggregates around an initial grain. These findings demonstrate the importance of dissipative effects in strongly correlated Rydberg gases and introduce a way to study spatio-temporal correlations in strongly-interacting many-body quantum systems without imaging.

description: Extended reality (XR) is a key innovation of 5G-advanced and beyond networks. The diverse XR use-cases, including virtual reality, augmented reality, and mixed reality, transform the way humans interact with surrounding environments. Thus, XR technology enables true immersive experiences of novel services spanning, e.g., e-commerce, healthcare, and education, respectively. However, the efficient support of XR services over existing and future cellular systems is highly challenging and requires multiple radio design improvements, due to the unique XR traffic and performance characteristics. Thus, this article surveys the state-of-art 3GPP standardization activities (release-18) for integrating the XR service class into the 5G-advanced specifications, highlighting the major XR performance challenges. Furthermore, the paper introduces valuable insights and research directions for supporting true XR services over the next-generation 6G networks, where multiple novel radio design mindsets and protocol enhancements are proposed and evaluated using extensive system level simulations, including solutions for application-native dynamic performance reporting, traffic-dependent control channel design, collaborative device aggregation for XR capacity boosting and offload, respectively.

description: Electricity generation and demand time series often are only available on a national scale. In this contribution, we derive regionalization factors to allocate publicly available national generation and demand time series for Germany to the federal-state level. We compare two different types of regionalization approaches: Static factors are based on the regional distribution of capacities or population and GPD, whereas dynamic factors take plant-specific generation time series, regionally resolved weather patterns or compositions of different load profiles into account. We observe that dynamic regionalization factors show significant temporal variability, emphasizing the limitations of static regionalization factors for a spatio-temporally more detailed representation of power system time series.

description: In a recent experiment [E. Vogt et al., Phys. Rev. Lett. 108, 070404 (2012)], quadrupole and breathing modes of a two-dimensional Fermi gas were studied. We model these collective modes by solving the Boltzmann equation via the method of phase-space moments up to fourth order, including in-medium effects on the scattering cross section. In our analysis, we use a realistic Gaussian potential deformed by the presence of gravity and magnetic field gradients. We conclude that the origin of the experimentally observed damping of the quadrupole mode, especially in the weakly interacting (or even non-interacting) case, cannot be explained by these mechanisms.

description: The abundance of models of complex networks and the current insufficient validation standards make it difficult to judge which models are strongly supported by data and which are not. We focus here on likelihood maximization methods for models of growing networks with many parameters and compare their performance on artificial and real datasets. While high dimensionality of the parameter space harms the performance of direct likelihood maximization on artificial data, this can be improved by introducing a suitable penalization term. Likelihood maximization on real data shows that the presented approach is able to discriminate among available network models. To make large-scale datasets accessible to this kind of analysis, we propose a subset sampling technique and show that it yields substantial model evidence in a fraction of time necessary for the analysis of the complete data.

Year: 2024
Subjects: subject: Natural Sciences

description: The structural and mechanical properties of biological tissues are intimately coupled with adequate organ function and tissue health. Optical coherence tomography (OCT) is extensively used in the study of human tissues, such as the cornea, skin and tympanic membrane, owing to its impressive resolution and depth range. However, diseases often manifest as tissue alterations below the resolution limit, and therefore, conventional intensity-based OCT is of limited use for early-stage detection or diagnosis. The aim of this work is to harness the sub-resolution signals from OCT to understand, detect and diagnose tissues. Vibrometric, nanosensitive and synthetic Fourier domain extensions of OCT were used to access sub-resolution signals related to the static and dynamic, structural and mechanical properties of tissue. Demonstration examples include corneal tissue, skin and stem cell spheroids. The vibrational resonance frequency modes of six corneal phantoms and two ex vivo rabbit corneas were successfully measured with the co-axial, acoustic optical coherence vibrometry probe. The resonance frequencies of the corneal phantoms showed sensitivity to the thickness, Young’s modulus and intraocular pressure of the phantoms. The resonance frequencies of the ex vivo rabbit corneas were observed to increase with increased intraocular pressure. The mean spatial period of mesenchymal stem cell pellets undergoing chondrogenic differentiation, measured with nanosensitive OCT, increased between days 1 and 4 and subsequently decreased between day 4 and 21. There was a net decrease in the mean spatial periodicity of the chondrogenic mesenchymal stem cell pellets of all three donors over the 21-day period of differentiation, in contrast to undifferentiated cells. Synthetic Fourier domain OCT intensity images of reference samples resolved the harmonic refractive index variations within small regions of the samples. Images of different regions of human skin tissue were imaged, and a difference of the structural spatial periodicity profiles within smaller regions was observed. A comparison between a nanosensitive OCT image and synthetic Fourier domain OCT colour map of a potato slice showed that the spatial resolution of the synthetic Fourier domain OCT colour map was approximately 10 times superior. The research detailed in this thesis demonstrates that the raw OCT interference signal manifests rich sub-resolution details which can be extracted for discovery and diagnosis of diseases and their mechanisms.

description: A variational method is discussed, based on the principle of minimal variance. The method seems to be suited for gauge interacting fermions, and the simple case of quantum electrodynamics is discussed in detail. The issue of renormalization is addressed, and the renormalized propagators are shown to be the solution of a set of finite integral equations. The method is proven to be viable and, by a spectral representation, the multi-dimensional integral equations are recast in one-dimensional equations for the spectral weights. The UV divergences are subtracted exactly, yielding a set of coupled Volterra integral equations that can be solved iteratively, and are known to have a unique solution.

description: Contexte et objectif. Bacillus cereus, germe commensal de l’environnement, est responsable d’infections potentiellement mortelles chez les nouveau-nés prématurés hospitalisés. L’objectif de ce travail est de décrire les mesures prises suite à trois sepsis à B. cereus en médecine et réanimation néonatales. Méthode. Ces sepsis ont été diagnostiquées les 14, 19 et 28 décembre 2019. L’équipe opérationnelle d’hygiène a été alertée le 29 décembre. La définition des mesures immédiates et la recherche des causes ont été faites par revue bibliographique, réunion de crise et étude des dossiers. La salle de naissance du bloc obstétrical a été nettoyée et désinfectée par la vapeur puis ses surfaces et celles des chambres des patients ont été prélevées. Les isolats bactériens ont été comparés par la recherche des gènes de toxines de B. cereus et le typage de séquences multilocus. Résultats. La réunion de crise a exclu le linge comme source de contamination et identifié le seul point géographique commun aux trois patients : la salle de naissance où, après nettoyage-désinfection par la vapeur, sur 38 prélèvements, seules les molettes d’aspiration de deux couveuses (5,3%) étaient positives à B. cereus. Dans les chambres, sur 24 prélèvements, seul un tiroir d’un chariot était positif (4,2%). D’après l’étude des dossiers, les autres sources de contamination possibles étaient la gestion du cathétérisme et de la nutrition parentérale. La comparaison des souches environnementales et cliniques a montré l’absence d’identité clonale. Conclusion. La réaction a été rapide : le nettoyage-désinfection par la vapeur a été effectué juste après la réunion de crise. Si cette action immédiate était motivée par certaines données bibliographiques, la comparaison des isolats a infirmé une transmission croisée sans exclure une origine environnementale.

description: A growing number of researchers present evidence that the pulsar wind nebula 3C58 is much older than predicted by its proposed connection to the historical supernova of A.D. 1181. There is also a great diversity of arguments. The strongest of these arguments rely heavily on the assumed distance of 3.2 kpc determined with HI absorption measurements. This publication aims at determining a more accurate distance for 3C58 and re-evaluating the arguments for a larger age. I have re-visited the distance determination of 3C58 based on new HI data from the Canadian Galactic Plane Survey and our recent improvements in the knowledge of the rotation curve of the outer Milky Way Galaxy. I have also used newly determined distances to objects in the neighbourhood, which are based on direct measurements by trigonometric parallax. I have derived a new more reliable distance estimate of 2 kpc for 3C58. This makes the connection between the pulsar wind nebula and the historical event from A.D. 1181 once again much more viable.

description: Retrieval finds a small number of relevant candidates from a large corpus for information retrieval and recommendation applications. A key component of retrieval is to model (user, item) similarity, which is commonly represented as the dot product of two learned embeddings. This formulation permits efficient inference, commonly known as Maximum Inner Product Search (MIPS). Despite its popularity, dot products cannot capture complex user-item interactions, which are multifaceted and likely high rank. We hence examine non-dot-product retrieval settings on accelerators, and propose \textit{mixture of logits} (MoL), which models (user, item) similarity as an adaptive composition of elementary similarity functions. This new formulation is expressive, capable of modeling high rank (user, item) interactions, and further generalizes to the long tail. When combined with a hierarchical retrieval strategy, \textit{h-indexer}, we are able to scale up MoL to 100M corpus on a single GPU with latency comparable to MIPS baselines. On public datasets, our approach leads to uplifts of up to 77.3\% in hit rate (HR). Experiments on a large recommendation surface at Meta showed strong metric gains and reduced popularity bias, validating the proposed approach's performance and improved generalization.

description: Nesoryzomys indefessus (Thomas, 1899). Ann. Mag. Nat. Hist., ser. 7, 4:280. TYPE LOCALITY: Ecuador, Galapagos Archipelago, Santa Cruz Island, Academia Bay. DISTRIBUTION: Santa Cruz, Baltra (= South Seymour), and Fernandina (= Narborough) islands. SYNONYMS: narboroughi. COMMENTS: Patton and Hafner (1983:539) recommended that indefessus, narboroughi, and swarthi are "best considered races of a single species, which differ primarily in pelage color." Their analyses sustain this conclusion with regard to indefessus and narboroughi but not the craniodental differentiation of N. swarthi. N. i. indefessus is probably extinct, none documented since 1934 (see Patton and Hafner, 1983). Populations of N. i. narboroughi on Fernandina Island, which lacks commensal Rattus and Mus, appear stable (see Patton and Hafner, 1983).

description: A countable set of superintegrable quantum mechanical systems is presented which admit the dynamical symmetry with respect to algebra so(4). This algebra is generated by the Laplace-Runge-Lenz vector generalized to the case of arbitrary spin. The presented systems describe neutral particles with non-trivial multipole momenta. Their spectra can be found algebraically like in the case of Hydrogen atom. Solutions for the systems with spins 1/2 and 1 are presented explicitly, solutions for spin 3/2 are expressed via solutions of an ordinary differential equation of first order..

Bottomonium suppression at $\sqrt{s_{NN}}=2.76$ TeV using model based on color screening and gluonic dissociation with collisional damping

description: We present a model to explain the bottomonium suppression in Pb+Pb collisions at mid rapidity obtained from Large Hadron Collider (LHC) energy, $\sqrt{s_{NN}}=2.76$ TeV. The model consists of two decoupled mechanisms namely, color screening during bottomonium production followed by gluon induced dissociation along with collisional damping. The quasi-particle model (QPM) is used as equation of state (EOS) for the Quark-Gluon Plasma (QGP) medium. The feed-down from higher $Υ$ states, such as $Υ(1P)$, $Υ(2S)$ and $Υ(2P)$, dilated formation times for bottomonium states and viscous effect of QGP medium are other ingredients included in the current formulation. We further assume that the QGP is expanding according to (1+1)-dimensional Bjorken's boost invariant scaling law. The net suppression (in terms of $p_T$ integrated survival probability) for bottomonium states at mid rapidity is obtained as a function of centrality and the result is then compared both quantitatively and qualitatively with the recent LHC experimental data in the mid rapidity region recently published by CMS collaboration. We find that the current model, based on the Debye color screening plus gluonic dissociation along with collisional damping, better describes the centrality dependence of bottomonium suppression at LHC energy as compared to color screening model alone. \vskip 0.5cm {\nd \it Keywords} : Color screening, Gluonic dissociation, Collisional damping, Survival probability {\nd \it PACS numbers} : 12.38.Mh, 12.38.Gc, 25.75.Nq, 24.10.Pa

DISTRIBUTION: Known only from San Salvador (= James, Santiago) Island. COMMENTS: Status viewed as a insular race of N. indefessus by Patton and Hafner (1983), but Orr (1938) underscored the trenchant diagnostic traits that separate N. swarthi from both N. indefessus and narboroughi. Remnant populations thought to exist as of 1965 (see Peterson, 1966b); recent efforts have uncovered only Rattus and Mus (see Patton and Hafner, 1983).

description: Although code generation for Convolution Neural Network (CNN) models has been extensively studied, performing efficient data slicing and parallelization for highly-constrai\-ned Multicore Neural Processor Units (NPUs) is still a challenging problem. Given the size of convolutions' input/output tensors and the small footprint of NPU on-chip memories, minimizing memory transactions while maximizing parallelism and MAC utilization are central to any effective solution. This paper proposes a TensorFlow XLA/LLVM compiler optimization pass for Multicore NPUs, called Tensor Slicing Optimization (TSO), which: (a) maximizes convolution parallelism and memory usage across NPU cores; and (b) reduces data transfers between host and NPU on-chip memories by using DRAM memory burst time estimates to guide tensor slicing. To evaluate the proposed approach, a set of experiments was performed using the NeuroMorphic Processor (NMP), a multicore NPU containing 32 RISC-V cores extended with novel CNN instructions. Experimental results show that TSO is capable of identifying the best tensor slicing that minimizes execution time for a set of CNN models. Speed-ups of up to 21.7\% result when comparing the TSO burst-based technique to a no-burst data slicing approach. To validate the generality of the TSO approach, the algorithm was also ported to the Glow Machine Learning framework. The performance of the models were measured on both Glow and TensorFlow XLA/LLVM compilers, revealing similar results.
Social identity and psychosis: a systematic review of social identity in the context of psychosis and related experiences; and, An empirical research study examining the association between social identity and paranoia, through the mediators of trust and hostile attribution bias

description: BACKGROUND: It is theorised there are important social factors in the development and maintenance of psychosis. Social identity theory states our sense of belonging to groups is internalised into our personal identity and research has demonstrated social identity is protective against physical and mental health difficulties. There is sound rationale for social identity being associated with psychosis and related experiences, both clinically and in the general population. AIMS: This thesis firstly aimed to conduct a systematic review exploring what research has been done to date exploring social identity in the context of psychosis. The second part of this thesis aimed to conduct an empirical study investigating the association of family and friendship group identity on paranoia, through the mediators of trust and hostile attribution bias. METHOD: The systematic review searched nine databases using relevant key words for research papers and judged these against inclusion and exclusion criteria. The quality of the final papers was assessed. A cross-sectional quantitative empirical study was conducted. Adults from the general population, including individuals with and without psychosis, were recruited. RESULTS: The systematic review revealed fourteen papers relevant to the research question. A narrative synthesis found stronger evidence for direct associations between small group social identities and psychosis-related experiences, and indirect associations for larger group social identities. The quality of papers was moderate to good with strengths in theoretical frameworks and limitations in sample representation. Findings from the empirical study showed social identity was a significant predictor of both paranoia and schizotypy. A mediation analysis found trust and hostile attribution bias significantly mediated this relationship. CONCLUSIONS: The results suggest there is an association between social identity and psychosis-related experiences. The strength of this association seems to depend on the type of social identity and the specific psychosis-related experience. The mechanisms of this relationship appear to be important and vary depending on the precise social identities and experiences. This has implications for considering the importance of social identity. A systematic review of social identity in the context of psychosis and related experiences.

description: Sampling techniques are used in many fields, including design of experiments, image processing, and graphics. The techniques in each field are designed to meet the constraints specific to that field such as uniform coverage of the range of each dimension or random samples that are at least a certain distance apart from each other. When an application imposes new constraints, for example, by requiring samples in a non-rectangular domain or the addition of new samples to an existing set, a common solution is to modify the algorithm currently in use, often with less than satisfactory results. As an alternative, we propose the concept of intelligent sampling, where we devise algorithms specifically tailored to meet our sampling needs, either by creating new algorithms or by modifying suitable algorithms from other fields. Surprisingly, both qualitative and quantitative comparisons indicate that some relatively simple algorithms can be easily modified to meet the many sampling requirements of surrogate modeling, hyperparameter optimization, and data analysis; these algorithms outperform their more sophisticated counterparts currently in use, resulting in better use of time and computer resources.
