description: In this paper, based on the Noda iteration, we present inexact Noda iterations (INI), to find the smallest eigenvalue and the associated positive eigenvector of a large irreducible nonsingular M-matrix. The positivity of approximations is critical in applications, and if the approximations lose the positivity then they will be physically meaningless. We propose two different inner tolerance strategies for solving the inner linear systems involved, and prove that the resulting INI algorithms are globally linear and superlinear with the convergence order $\frac{1+\sqrt{5}}{2}$, respectively. The proposed INI algorithms are structure preserving and maintains the positivity of approximate eigenvectors. We also revisit the exact Noda iteration and establish a new quadratic convergence result. All the above is first done for the problem of computing the Perron root and the positive Perron vector of an irreducible nonnegative matrix and then adapted to that of computing the smallest eigenpair of the irreducible nonsingular M-matrix. Numerical examples illustrate that the proposed INI algorithms are practical, and they always preserve the positivity of approximate eigenvectors. We compare them with the positivity non-preserving Jacobi--Davidson method and implicitly restarted Arnoldi method, which often compute physically meaningless eigenvectors, and illustrate that the overall efficiency of the INI algorithms is competitive with and can be considerably higher than the latter two methods.

description: We investigate SU(3) gauge theories in four dimensions with Nf fundamental fermions, on a lattice using the Wilson fermion. Clarifying the vacuum structure in terms of Polyakov loops in spatial directions and properties of temporal propagators using a new method "local analysis", we conjecture that the "conformal region" exists together with the confining region and the deconfining region in the phase structure parametrized by beta and K, both in the cases of the large Nf QCD within the conformal window (referred as Conformal QCD) with an IR cutoff and small Nf QCD at T/Tc>1 with Tc being the chiral transition temperature (referred as High Temperature QCD). Our numerical simulation on a lattice of the size 16^3 x 64 shows the following evidence of the conjecture. In the conformal region we find the vacuum is the nontrivial Z(3) twisted vacuum modified by non-perturbative effects and temporal propagators of meson behave at large t as a power-law corrected Yukawa-type decaying form. The transition from the conformal region to the deconfining region or the confining region is a sharp transition between different vacua and therefore it suggests a first order transition both in Conformal QCD and in High Temperature QCD. Within our fixed lattice simulation, we find that there is a precise correspondence between Conformal QCD and High Temperature QCD in the temporal propagators under the change of the parameters Nf and T/Tc respectively. In particular, we find the correspondence between Conformal QCD with Nf = 7 and High Temperature QCD with Nf=2 at T ~ 2 Tc being in close relation to a meson unparticle model. From this we estimate the anomalous mass dimension gamma* = 1.2 (1) for Nf=7. We also show that the asymptotic state in the limit T/Tc --> infty is a free quark state in the Z(3) twisted vacuum.

description: In recent years, Edge Computing has emerged as a new computing paradigm that leverages computing resources close to clients, paving the way for latency-sensitive applications like industrial IoT or urban augmented reality. Many of these applications use publish-subscribe patterns for communications that use message brokers for data dissemination. Currently, most message brokers focus on deployments in the cloud. However, the connections between clients and cloud brokers introduce latencies that some applications might not tolerate. Edge computing resources offer a possible location to deploy brokers closer to clients, reducing latency. We designed a distributed broker system that makes use of edge resources to improve Quality of Service. Our approach consists of proximity detection by using a network coordinate system, along with self-adaptive broker orchestration. Using network coordinates allows us to estimate distances instead of having to measure them, reducing monitoring overhead and network strain. The broker orchestration starts and stops broker instances on edge resources on demand, using local pressure on edge nodes by close clients to decide whether to start a broker or not. We evaluate our system in a simulated environment with scenarios and topologies that are representative for IoT applications. Results show that we can use a network coordinate system to accurately find the closest broker for a client, and at the same time reduce the number distance measurements by at least one order of magnitude. We also show that the broker scaling mechanism dynamically deploys brokers on the edge resources close to the clients, while taking the tradeoff between end-to-end latency and resource consumption into account.

description: Intrinsic image decomposition aims to separate the surface reflectance and the effects from the illumination given a single photograph. Due to the complexity of the problem, most prior works assume a single-color illumination and a Lambertian world, which limits their use in illumination-aware image editing applications. In this work, we separate an input image into its diffuse albedo, colorful diffuse shading, and specular residual components. We arrive at our result by gradually removing first the single-color illumination and then the Lambertian-world assumptions. We show that by dividing the problem into easier sub-problems, in-the-wild colorful diffuse shading estimation can be achieved despite the limited ground-truth datasets. Our extended intrinsic model enables illumination-aware analysis of photographs and can be used for image editing applications such as specularity removal and per-pixel white balancing.

description: In thin topological insulator films, the top and bottom surfaces are coupled by tunneling, which restores backscattering and strongly affects screening. We calculate the dielectric function in the random phase approximation obtaining a closed-form result. Unlike independent TI surfaces, the dielectric function of thin films exhibits a valley as a function of wavenumber $q$ and tunneling, as well as a cusp at $q=2k_F$, with $k_F$ the Fermi wave vector. As a result of the cusp, Friedel oscillations decay with distance $r$ as $\sin(2k_Fr)/(2k_Fr)^2$. We determine the longitudinal conductivity $σ$ in the first Born approximation at low temperatures where screened impurities provide the dominant scattering mechanism. At high electron densities $n_e$, $σ\propto n_e$, while at low densities $σ\propto n_e^{3/2}$.

description: As the world undergoes significant digital technological advancements, many believe that traditional education systems are not providing the essential competencies learners require for the future (Istance & Kools, 2013; Joynes et al., 2019). With an ever-increasing critical digital skills gap (Meechan, 2021; S. Wright, 2018), today's learners must be encouraged to develop their digital prowess (Skills Development Scotland, 2018; S. Wright, 2018) and develop the meta-competencies required for the world they are to inhabit (Beetham & Sharpe, 2013; The Scottish Government, 2020; Trilling & Fadel, 2009). Many feel compulsory education fails to provide learners with the requisite digital computing competencies (Istance & Kools, 2013; Joynes et al., 2019). Therefore, more engaging and effective alternatives to our current curriculum content delivery and high-stake examinations must be examined. This proposal and research study examine an alternative method of developing digital computing competencies by employing a social constructivist (SC) approach using a design thinking (DT) model, also purported to develop the much-needed meta-competencies (MC) learners need in the future (Fairburn, 2010; Goldman & Kabayadondo, 2016; Koh et al., 2015). Internationally renowned universities such as the Massachusetts Institute of Technology (MIT), Stanford, and Berkeley use DT to develop MC; however, there is little research into DT studios in a compulsory educational setting (Carroll, 2015). This opportunistic, single-case study details a school's journey to develop outcomes from a digitally focused design thinking studio integrated into its curriculum, examining the perceptions and experiences of outcomes from learners and educators immersed in a two-week digital DT studio. This study should be of interest to educators, policymakers, and parents.

description: Redshift-space distortions (RSD) offer an attractive method to measure the growth of cosmic structure on large scales, and combining with the measurement of the cosmic expansion history, it can be used as cosmological tests of gravity. With the advent of future galaxy redshift surveys aiming at precisely measuring the RSD, an accurate modeling of RSD going beyond linear theory is a critical issue in order to detect or disprove small deviations from general relativity (GR). While several improved models of RSD have been recently proposed based on the perturbation theory (PT), the framework of these models heavily relies on GR. Here, we put forward a new PT prescription for RSD in general modified gravity models. As a specific application, we present theoretical predictions of the redshift-space power spectra in f(R) gravity model, and compare them with N-body simulations. Using the PT template that takes into account the effects of both modifications of gravity and RSD properly, we successfully recover the fiducial model parameter in N-body simulations in an unbiased way. On the other hand, we found it difficult to detect the scale dependence of the growth rate in a model-independent way based on GR templates.

description: 3DBionotes-WS is a web application designed to automatically annotate biochemical and biomedical information onto structural models in a fully interactive 3D graphical environment. Current sources of information include domain families, genomic variations associated with diseases, immune epitope sites, short linear motifs, disordered regions and post-translational modifications that can be explored interactively at the sequence and structural level. 3DBionotes-WS is always in continuous expansion and looking for new data types to integrate.

 The imaging data field has experienced very fast growth in content and complexity. The size of biological image datasets is quite large, which makes it hard to submit, manage and publish data. Metadata defining imaging protocols, biological systems or the processing outputs sometimes are not properly included in publications, making it difficult to analyse datasets. For that reason, in the last few years, it has become crucial to create an infrastructure for image data standardisation, deposition, sharing and, in the end, better data availability.

 A few initiatives have arisen to fulfil this need, being the Image Data Resource (IDR) & the BioImage Archive (BIA) some of the more relevant. Among all the useful data provided by these repositories, we have focused on the results from High-Content Screening experiments for SARS-CoV-2 and a well-defined collection of compounds with potential clinical use. 3DBionotes-WS users will be able to search for COVID-19-related macromolecular structures bound to a ligand already tested with the corresponding link to the experimental data source for further reference.
Enhanced Gravity Model of trade: reconciling macroeconomic and network models

description: The structure of the International Trade Network (ITN), whose nodes and links represent world countries and their trade relations respectively, affects key economic processes worldwide, including globalization, economic integration, industrial production, and the propagation of shocks and instabilities. Characterizing the ITN via a simple yet accurate model is an open problem. The traditional Gravity Model (GM) successfully reproduces the volume of trade between connected countries, using macroeconomic properties such as GDP, geographic distance, and possibly other factors. However, it predicts a network with complete or homogeneous topology, thus failing to reproduce the highly heterogeneous structure of the ITN. On the other hand, recent maximum-entropy network models successfully reproduce the complex topology of the ITN, but provide no information about trade volumes. Here we integrate these two currently incompatible approaches via the introduction of an Enhanced Gravity Model (EGM) of trade. The EGM is the simplest model combining the GM with the network approach within a maximum-entropy framework. Via a unified and principled mechanism that is transparent enough to be generalized to any economic network, the EGM provides a new econometric framework wherein trade probabilities and trade volumes can be separately controlled by any combination of dyadic and country-specific macroeconomic variables. The model successfully reproduces both the global topology and the local link weights of the ITN, parsimoniously reconciling the conflicting approaches. It also indicates that the probability that any two countries trade a certain volume should follow a geometric or exponential distribution with an additional point mass at zero volume.

description: We propose a general method for constructing a minimal cover of high-dimensional chaotic attractors by embedded unstable recurrent patterns. By minimal cover we mean a subset of available patterns such that the approximation of chaotic dynamics by a minimal cover with a predefined proximity threshold is as good as the approximation by the full available set. The proximity measure, based on the concept of a directed Hausdorff distance, can be chosen with considerable freedom and adapted to the properties of a given chaotic system. In the context of a spatiotemporally chaotic attractor of the Kuramoto--Sivashinsky system on a periodic domain, we demonstrate that the minimal cover can be faithfully constructed even when the proximity measure is defined within a subspace of dimension much smaller than the dimension of space containing the attractor. We discuss how the minimal cover can be used to provide a reduced description of the attractor structure and the dynamics on it.

description: We present reverse Hölder inequalities for Muckenhoupt weights in $\mathbb{R}^n$ with an asymptotically sharp behavior for flat weights, namely $A_\infty$ weights with Fujii-Wilson constant $(w)_{A_\infty}\to 1^+$. That is, the local integrability exponent in the reverse Hölder inequality blows up as the weight becomes nearly constant. This is expressed in a precise and explicit computation of the constants involved in the reverse Hölder inequality. The proofs avoid BMO methods and rely instead on precise covering arguments. Furthermore, in the one-dimensional case we prove sharp reverse Hölder inequalities for one-sided and two sided weights in the sense that both the integrability exponent as well as the multiplicative constant appearing in the estimate are best possible. We also prove sharp endpoint weak-type reverse Hölder inequalities and consider further extensions to general non-doubling measures and multiparameter weights.

description: We study the effect of weak lensing by cosmic (super-)strings on the higher-order statistics of the cosmic microwave background (CMB). A cosmic string segment is expected to cause weak lensing as well as an integrated Sachs-Wolfe (ISW) effect, the so-called Gott-Kaiser-Stebbins (GKS) effect, to the CMB temperature fluctuation, which are thus naturally cross-correlated. We point out that, in the presence of such a correlation, yet another kind of the post-recombination CMB temperature bispectra, the ISW-lensing bispectra, will arise in the form of products of the auto- and cross-power spectra. We first present an analytic method to calculate the autocorrelation of the temperature fluctuations induced by the strings, and the cross-correlation between the temperature fluctuation and the lensing potential both due to the string network. In our formulation, the evolution of the string network is assumed to be characterized by the simple analytic model, the velocity-dependent one scale model, and the intercommutation probability is properly incorporated in orderto characterize the possible superstringy nature. Furthermore, the obtained power spectra are dominated by the Poisson-distributed string segments, whose correlations are assumed to satisfy the simple relations. We then estimate the signal-to-noise ratios of the string-induced ISW-lensing bispectra and discuss the detectability of such CMB signals from the cosmic string network. It is found that in the case of the smaller string tension, $Gμ\ll 10^{-7}$\,, the ISW-lensing bispectrum induced by a cosmic string network can constrain the string-model parameters even more tightly than the purely GKS-induced bispectrum in the ongoing and future CMB observations on small scales.

description: Quantum decoherence is the loss of a system's purity due to its interaction with the surrounding environment. Via the AdS/CFT correspondence, we study how a system decoheres when its environment is a strongly-coupled theory. In the Feynman-Vernon formalism, we compute the influence functional holographically by relating it to the generating function of Schwinger-Keldysh propagators and thereby obtain the dynamics of the system's density matrix. We present two exactly solvable examples: (1) a straight string in a BTZ black hole and (2) a scalar probe in AdS$_5$. We prepare an initial state that mimics Schrödinger's cat and identify different stages of its decoherence process using the time-scaling behaviors of Rényi entropy. We also relate decoherence to local quantum quenches, and by comparing the time evolution behaviors of the Wigner function and Rényi entropy we demonstrate that the relaxation of local quantum excitations leads to the collapse of its wave-function.

description: The aim of this work is to complete our program on the quantization of connections on arbitrary principal U(1)-bundles over globally hyperbolic Lorentzian manifolds. In particular, we show that one can assign via a covariant functor to any such bundle an algebra of observables which separates gauge equivalence classes of connections. The C*-algebra we construct generalizes the usual CCR-algebras since, contrary to the standard field-theoretic models, it is based on a presymplectic Abelian group instead of a symplectic vector space. We prove a no-go theorem according to which neither this functor, nor any of its quotients, satisfies the strict axioms of general local covariance. As a byproduct, we prove that a morphism violates the locality axiom if and only if a certain induced morphism of cohomology groups is non-injective. We then show that fixing any principal U(1)-bundle, there exists a suitable category of sub-bundles for which a quotient of our functor yields a quantum field theory in the sense of Haag and Kastler. We shall provide a physical interpretation of this feature and we obtain some new insights concerning electric charges in locally covariant quantum field theory.

description: This paper provides a necessary and sufficient condition on Tauberian constants associated to a centered translation invariant differentiation basis so that the basis is a density basis. More precisely, given $x \in \mathbb{R}^n$, let $\mathcal{B} = \cup_{x \in \mathbb{R}^n} \mathcal{B}(x)$ be a collection of bounded open sets in $\mathbb{R}^n$ containing $x$. Suppose moreover that these collections are translation invariant in the sense that, for any two points $x$ and $y$ in $\mathbb{R}^n$ we have that $\mathcal{B}(x + y) = \{R + y : R \in \mathcal{B}(x)\}.$ Associated to these collections is a maximal operator $M_{\mathcal{B}}$ given by $$M_{\mathcal{B}}f(x) :=\sup_{R \in \mathcal{B}(x)} \frac{1}{|R|} \int_R |f|.$$ The Tauberian constants $C_{\mathcal{B}}(α)$ associated to $M_{\mathcal{B}}$ are given by $$C_{\mathcal{B}}(α) :=\sup_{E \subset \mathbb{R}^n \atop 0 < |E| < \infty} \frac{1}{|E|}|\{x \in \mathbb{R}^n :\, M_{\mathcal{B}}χ_E(x) > α\}|.$$ Given $0 < r < \infty$, we set $\mathcal{B}_r(x) :=\{R \in \mathcal{B}(x) : \mathrm{diam } R < r\}$, and let $\mathcal{B}_r :=\cup_{x \in \mathbb{R}^n} \mathcal{B}_r (x).$ We prove that $\mathcal{B}$ is a density basis if and only if, given $0 < α< \infty$, there exists $ r = r(α) >0$ such that $C_{\mathcal{B}_r}(α) < \infty$. Subsequently, we construct a centered translation invariant density basis $\mathcal{B} = \cup_{x \in \mathbb{R}^n} \mathcal{B}(x)$ such that there does not exist any $0 < r$ satisfying $C_{\mathcal{B}_{r}}(α) < \infty$ for all $0 < α< 1$.

description: We establish the sharp growth rate, in terms of cardinality, of the $L^p$ norms of the maximal Hilbert transform $H_Ω$ along finite subsets of a finite order lacunary set of directions $Ω\subset \mathbb R^3$, answering a question of Parcet and Rogers in dimension $n=3$. Our result is the first sharp estimate for maximal directional singular integrals in dimensions greater than 2.
 The proof relies on a representation of the maximal directional Hilbert transform in terms of a model maximal operator associated to compositions of two-dimensional angular multipliers, as well as on the usage of weighted norm inequalities, and their extrapolation, in the directional setting.

description: The statistics of large-scale structure in the Universe can be used to probe non-Gaussianity of the primordial density field, complementary to existing constraints from the cosmic microwave background. In particular, the scale dependence of halo bias, which affects the halo distribution at large scales, represents a promising tool for analyzing primordial non-Gaussianity of local form. Future observations, for example, may be able to constrain the trispectrum parameter gNL that is difficult to study and constrain using the CMB alone. We investigate how galaxy and matter bispectra can distinguish between the two non-Gaussian parameters fNL and gNL, whose effects give nearly degenerate contributions to the power spectra. We use a generalization of the univariate bias approach, making the hypothesis that the number density of halos forming at a given position is a function of the local matter density contrast and of its local higher-order statistics. Using this approach, we calculate the halo-matter bispectra and analyze their properties. We determine a connection between the sign of the halo bispectrum on large scales and the parameter gNL. We also construct a combination of halo and matter bispectra that is sensitive to fNL, with little contamination from gNL. We study both the case of single and multiple sources to the primordial gravitational potential, discussing how to extend the concept of stochastic halo bias to the case of bispectra. We use a specific halo mass-function to calculate numerically the bispectra in appropriate squeezed limits, confirming our theoretical findings.

description: We describe how to obtain the gravity duals of semiclassical states in the D1-D5 CFT that are superdescendants of a class of RR ground states. On the gravity side, the configurations we construct are regular and asymptotically reproduce the 3-charge D1-D5-P black hole compactified on $S^1\times T^4$. The geometries depend trivially on the $T^4$ directions but non-trivially on the remaining 6D space. In the decoupling limit, they reduce to asymptotically AdS$_3 \times S^3 \times T^4$ spaces that are dual to CFT states obtained by acting with (exponentials of) the operators of the superconformal algebra. As explicit examples, we generalise the solution first constructed in arXiv:1306.1745 and discuss another class of states that have a more complicated dual geometry. By using the free orbifold description of the CFT we calculate the average values for momentum and the angular momenta of these configurations. Finally we compare the CFT results with those obtained in the bulk from the asymptotically $M^{1,4} \times S^1\times T^4$ region.

description: The nature of accretion onto stellar mass black holes in the low/hard state remains unresolved, with some evidence suggesting that the inner accretion disc is truncated and replaced by a hot flow. However, the detection of relativistic broadened Fe emission lines, even at relatively low luminosities, seems to require an accretion disc extending fully to its innermost stable circular orbit. Modelling such features is however highly susceptible to degeneracies, which could easily bias any interpretation. We present the first systematic study of the Fe line region to track how the inner accretion disc evolves in the low/hard state of the black hole GX 339$-$4. Our four observations display increased broadening of the Fe line over two magnitudes in luminosity, which we use to track any variation of the disc inner radius. We find that the disc extends closer to the black hole at higher luminosities, but is consistent with being truncated throughout the entire low/hard state, a result which renders black hole spin estimates inaccurate at these stages of the outburst. Furthermore, we show that the evolution of our spectral inner disc radius estimates corresponds very closely to the trend of the break frequency in Fourier power spectra, supporting the interpretation of a truncated and evolving disc in the hard state.

description: Enzymatic bioelectrochemistry represents the marriage of electrochemistry and enzymatic biocatalysis, and has led to important applications for biosensors, biofuel cells, and bioelectrocatalysis. Enzyme immobilization is the basis of enzymatic bioelectrochemistry, as immobilization itself determines the enzyme/material interface and thus the electrochemical performance. Amongst the range of methods of enzyme immobilization, one-step electrochemical approaches feature rapid immobilization and good control over the processes, enabling par?tial or total use of the electrode surface. In this mini-review, we first briefly introduce the operating principles of bioelectrochemical applications based on enzyme modified electrodes. We then overview recent progress in utilizing conductive polymers, redox-active modified polymers, sol–gel silica and electrochemically assistant adsorption for enzyme immobilization via one-step electrochemical approaches. The use of conductive polymers for in situ enzyme immobilization is our major focus. Perspectives for future work are also described.

description: We establish the sharp growth order, up to epsilon losses, of the $L^2$-norm of the maximal directional averaging operator along a finite subset $V$ of a polynomial variety of arbitrary dimension $m$, in terms of cardinality. This is an extension of the works by Córdoba, for one-dimensional manifolds, Katz for the circle in two dimensions, and Demeter for the 2-sphere. For the case of directions on the two-dimensional sphere we improve by a factor of $\sqrt{\log N}$ on the best known bound, due to Demeter, and we obtain a sharp estimate for our model operator. Our results imply new $L^2$-estimates for Kakeya-type maximal functions with tubes pointing along polynomial directions. Our proof technique is novel and in particular incorporates an iterated scheme of polynomial partitioning on varieties adapted to directional operators, in the vein of Guth, Guth-Katz, and Zahl.

description: Estas guías destacan lo que hemos aprendido de las actividades y la recopilación de datos de LIAISON. El objetivo es ayudar a todos los que las utilizan a mejorar su forma de co-innovar en la agricultura, la silvicultura y el desarrollo rural. LIAISON (Better Rural Innovation: Linking Actors, Instruments and Policies through Networks) es un proyecto multiactor que ha sido financiado dentro de la EIP Agri, una iniciativa lanzada por la Comisión Europea en 2012 con su objetivo de fomentar una agricultura y una silvicultura competitivas y sostenibles que “consigan más y mejor con menos”. El enfoque de la innovación interactiva reúne a una amplia gama de actores públicos y privados de la innovación (agricultores, asesores, investigadores, empresas, ONG, etc.) con conocimientos y experiencia complementarios para valorar, reunir, co-crear y difundir soluciones prácticas a las necesidades reales de los agricultores y silvicultores. Estas necesidades están impulsadas por, y se derivan de, las oportunidades reales y los retos cotidianos a los que se enfrentan los agricultores, los silvicultores y las empresas rurales. Las innovaciones generadas mediante un enfoque interactivo pueden aportar soluciones bien adaptadas a las circunstancias y más fáciles de aplicar.
