description: This chapter deals with kernel methods as a special class of techniques for surrogate modeling. Kernel methods have proven to be efficient in machine learning, pattern recognition and signal analysis due to their flexibility, excellent experimental performance and elegant functional analytic background. These data-based techniques provide so called kernel expansions, i.e., linear combinations of kernel functions which are generated from given input-output point samples that may be arbitrarily scattered. In particular, these techniques are meshless, do not require or depend on a grid, hence are less prone to the curse of dimensionality, even for high-dimensional problems. In contrast to projection-based model reduction, we do not necessarily assume a high-dimensional model, but a general function that models input-output behavior within some simulation context. This could be some micro-model in a multiscale-simulation, some submodel in a coupled system, some initialization function for solvers, coefficient function in PDEs, etc. First, kernel surrogates can be useful if the input-output function is expensive to evaluate, e.g. is a result of a finite element simulation. Here, acceleration can be obtained by sparse kernel expansions. Second, if a function is available only via measurements or a few function evaluation samples, kernel approximation techniques can provide function surrogates that allow global evaluation. We present some important kernel approximation techniques, which are kernel interpolation, greedy kernel approximation and support vector regression. Pseudo-code is provided for ease of reproducibility. In order to illustrate the main features, commonalities and differences, we compare these techniques on a real-world application. The experiments clearly indicate the enormous acceleration potential

description: Abstract Background: The workforces in the growing flower farms of Ethiopia are mainly females. Greenhouse workers are exposed to pesticides, fertilizers and dust, and might be at risk for developing respiratory diseases. Objectives: This study aimed to assess respiratory symptoms and lung function of greenhouse workers and compare them to packinghouse flower farm workers. Methods: A comparative cross-sectional study was conducted comparing female flower farmworkers from greenhouses, with female workers in packinghouses. Participants were interviewed for chronic respiratory symptoms using a standardized questionnaire from the British Medical Research Council. A Minispir light spirometer, with Winspiro software was used for lung function tests to measure Forced vital capacity (FVC) and Forced expiratory volume at one second (FEV1). Study groups background characteristics were compared using an independent t-test and chi-square test. Poisson regression analysis and a general linear model were also performed. Results: Three hundred fourteen workers participated,160 from greenhouses and 159 from pack houses. The response rate showed that 99.7% was for the interview and 98% was for spirometry. The mean (SD) age of greenhouse workers was 26(8) years and of packinghouse workers 24(7) years. There was no significant difference in respiratory symptoms and spirometry indices while comparing workers in greenhouse with workers from packinghouse. But service month was a significant predictor for the reduction of FEV1, by a reduction of 2ml/month with a p-value of 0.01. Conclusion: There was no difference in respiratory symptoms and lung function parameters comparing greenhouse and packinghouse workers from flower farms. Service duration was a significant predictor for the reduction of FEV1. This may indicate the development of lung obstruction among flower farm workers over a course of time. Workers respiratory health including lung function change needs to be monitored regularly. [Ethiop. J. Health Dev. 2023; 37(1) 000-000]

description: The Gruenberg-Kegel graph $Γ(G)$ associated with a finite group $G$ has as vertices the prime divisors of $|G|$, with an edge from $p$ to $q$ if and only if $G$ contains an element of order $pq$. This graph has been the subject of much recent interest; one of our goals here is to give a survey of some of this material, relating to groups with the same Gruenberg-Kegel graph. However, our main aim is to prove several new results. Among them are the following. - There are infinitely many finite groups with the same Gruenberg-Kegel graph as the Gruenberg-Kegel of a finite group $G$ if and only if there is a finite group $H$ with non-trivial solvable radical such that $Γ(G)=Γ(H)$. - There is a function $F$ on the natural numbers with the property that if a finite $n$-vertex graph whose vertices are labelled by pairwise distinct primes is the Gruenberg-Kegel graph of more than $F(n)$ finite groups, then it is the Gruenberg-Kegel graph of infinitely many finite groups. (The function we give satisfies $F(n)=O(n^7)$, but this is probably not best possible.) - If a finite graph $Γ$ whose vertices are labelled by pairwise distinct primes is the Gruenberg-Kegel graph of only finitely many finite groups, then all such groups are almost simple; moreover, $Γ$ has at least three pairwise non-adjacent vertices, and $2$ is non-adjacent to at least one odd vertex. - Groups whose power graphs, or commuting graphs, are isomorphic have the same Gruenberg-Kegel graph. - The groups ${^2}G_2(27)$ and $E_8(2)$ are uniquely determined by the isomorphism types of their Gruenberg-Kegel graphs. In addition, we consider groups whose Gruenberg-Kegel graph has no edges. These are the groups in which every element has prime power order, and have been studied under the name \emph{EPPO groups}; completing this line of research, we give a complete list of such groups.

description: In 2010, V. Futorny and S. Ovsienko gave a realization of $U(\mathfrak{gl}_n)$ as a subalgebra of the ring of invariants of a certain noncommutative ring with respect to the action of $S_1\times S_2\times\cdots\times S_n$, where $S_j$ is the symmetric group on $j$ variables. An interesting question is what a similar algebra would be in the invariant ring with respect to a product of alternating groups. In this paper we define such an algebra, denoted $\mathscr{A}(\mathfrak{gl}_n)$, and show that it is a Galois ring. For $n=2$, we show that it is a generalized Weyl algebra, and for $n=3$ provide generators and a list of verified relations. We also discuss some techniques to construct Galois orders from Galois rings. Additionally, we study categories of finite-dimensional modules and generic Gelfand-Tsetlin modules over $\mathscr{A}(\mathfrak{gl}_n)$. Finally, we discuss connections between the Gelfand-Kirillov Conjecture, $\mathscr{A}(\mathfrak{gl}_n)$, and the positive solution to Noether's problem for the alternating group.

description: We discuss the possibility that suitable modifications of gravity could account for some amount of the radiation we observe today, in addition to the possibility of explaining the present speed up of the universe. We start introducing and reviewing cosmological reconstruction methods for metric $f(R)$ theories of gravity that can be considered as one of the straightforward modifications of Einstein's gravity as soon as $f(R)\neq R$. We then take into account two possible $f(R)$ models which could give rise to (dark) radiation. Constraints on the models are found by using the Planck Collaboration 2015 data within a cosmographic approach and by obtaining the matter power spectrum of those models. The conclusion is that $f(R)$ gravity can only contribute minimally to the (dark) radiation to avoid departures from the observed matter power spectrum at the smallest scales (of the order of $0.01$Mpc$^{-1}$), i.e., precisely those scales that exited the horizon at the radiation dominated epoch. This result could strongly contribute to select reliable $f(R)$ models.

description: Abstract Background: The increasing burden of chronic non-communicable diseases (NCDs) in low- and middle-income countries (LMICs) calls for the development and dissemination of effective and viable interventions. In this respect, behavioral and lifestyle modification interventions (BLMIs) offer the most effective means of addressing the underlying lifestyle behaviors associated with NCDs at multiple disease prevention levels (primordial, primary, and secondary). This review aims to provide an overview of key features and components of BLMIs as well as some practical considerations when implementing them in LMIC settings. Methods: An exploratory approach was used to provide an overview of salient issues in the design of BLMIs; and the PubMed and Google Scholar databases, as well as gray literature, were searched. Based on the review‘s aim, the most important issues and themes were identified using a narrative thematic synthesis and analysis approach. Results: Thirty-three publications were included as the most relevant literature to the topic, and eight overarching themes were identified: understanding the target health behavior; using behavioral and psychological theories; applying behavior change techniques/strategies; providing effective support and follow-up; intervention delivery formats and providers; cultural sensitivity; feasibility consideration; and addressing multiple lifestyle behaviors. Conclusion: Targeting lifestyle and behavioral modification interventions with a proper understanding of their essential design components and practical contextual considerations is crucial for reducing the rising burden of NCDs in LMICs. Future direction on the importance of conducting original research and systematic reviews on the subject was also emphasized. [Ethiop. J.

description: The probabilistic investigation on record values and record times of a sequence of random variables defined on the same probability space has received much attention from 1952 to now. A great deal of such theory focused on \textit{iid} or independent real-valued random variables. There exists a few results for real-valued dependent random variables. Some papers deal also with multivariate random variables. But a large theory regarding vectors and dependent data has yet to be done. In preparation of that, the probability laws of records are investigated here, without any assumption on the dependence structure. The results are extended sequences with values in partially ordered spaces whose order is compatible with measurability. The general characterizations are checked in known cases mostly for \textit{iid} sequences. The frame is ready for undertaking a vast study of records theory in high dimensions and for types of dependence.

description: Abstract Background: Patients’ relatives usually care for patients of with schizophrenia. Caregivers can experience some difficulties during the caregiving process. This can increase the burden of caregivers. This study aimed to determine the requirements of primary caregivers of schizophrenia patients and its effect on caregiver burden. Methods: The sample of the cross-sectional study consisted of 94 caregivers of patients with schizophrenia who were treated at the university hospital in western Turkey and agreed to participate in this study. A questionnaire form and Caregiving Burden Scale were used to collect data. The data were collected from individual interviews between March-December 2015. Results: The average score of Caregiving Burden Scale of the primary caregivers is was determined as 38.47±15.05. Based on this the primary caregivers had difficulty in giving medication to their patients, the requirement of knowledge about drug treatment and side effects, coping with symptoms of schizophrenia, early warning signs, communication skills, coping with stress, psychosocial treatment methods, planning of the patients' leisure activities, and contribution of the patient to home life affected the caregiving burden having a p value of (p<0.05). Conclusions: The overall Caregiving Burden Scale mean score of caregivers was considered moderate. It can be conclude that caregivers' requirements affect the burden of care during the caregiving process. It was considered that the feeling of burden care for caregivers will be able to reduce by giving consultancy services related to what they need and with the creation of comprehensive, systematic, continuous education programs including the difficulties faced by caregivers and the requirements being able to cope easily with the difficulties during caregiving.

description: This paper presents a set of new formulations for the Flying Sidekick Traveling Salesman Problem, where a truck and a drone cooperate to delivery parcels to customers minimizing the completion time. The new formulations improve the results of the literature by solving to optimality several benchmark instances for which an optimal solution was previously unknown. A matheuristic algorithm, strongly based on the new models, is also discussed. Experimental results show that this method is able to provide good quality solutions in short time even for the larger instances, on which the mathematical models struggle to provide either good heuristic solution or strong lower bounds.

description: Abstract Background: Digital literacy and acceptability of electronic data management devices are critical factors for proper data management and use. In Ethiopia, the electronic community health information system has been introduced in 2018. However, little is known about the digital literacy and acceptability of electronic devices by Ethiopian health extension workers. This study aims to assess digital literacy and explore the acceptability of digital devices among health extension workers in Tiro Afata Woreda, Southwest Ethiopia. Methods: A facility-based case study was conducted using quantitative and qualitative research methods from March to April 2021. Data were collected from 45 health extension workers. Seven questions (items) were used to measure digital literacy, and attitude of health extension workers was examined using 10 items. We have computed index for digital literacy and attitude toward digital technologies. Descriptive statistics was used to analyse and describe characteristics of health workers and outcome variables, and thematic analysis was performed for qualitative data. Results: Less than half (11 or 45.8%) of health extension workers had high digital literacy, and positive attitude towards digital tools. The health extension workers mentioned that the factors including benefits and user friendliness of the digital tool, and presence of technical and material supports were facilitators to acceptability of electronic community health information system. Whereas, the overburdened responsibilities of the health extension worker beyond health extension program activities was an impediment to acceptability and proper use of eCHIS. Conclusions: The health extension workers level of digital literacy and attitude towards mobile applications was relatively low. Hence, the implementation of community-level electronic health information systems should take into consideration the digital literacy, and the factors that impede acceptability of digital tools.

description: We present a general, efficient technique for providing contextual predictions that are "multivalid" in various senses, against an online sequence of adversarially chosen examples $(x,y)$. This means that the resulting estimates correctly predict various statistics of the labels $y$ not just marginally -- as averaged over the sequence of examples -- but also conditionally on $x \in G$ for any $G$ belonging to an arbitrary intersecting collection of groups $\mathcal{G}$. We provide three instantiations of this framework. The first is mean prediction, which corresponds to an online algorithm satisfying the notion of multicalibration from Hebert-Johnson et al. The second is variance and higher moment prediction, which corresponds to an online algorithm satisfying the notion of mean-conditioned moment multicalibration from Jung et al. Finally, we define a new notion of prediction interval multivalidity, and give an algorithm for finding prediction intervals which satisfy it. Because our algorithms handle adversarially chosen examples, they can equally well be used to predict statistics of the residuals of arbitrary point prediction methods, giving rise to very general techniques for quantifying the uncertainty of predictions of black box algorithms, even in an online adversarial setting. When instantiated for prediction intervals, this solves a similar problem as conformal prediction, but in an adversarial environment and with multivalidity guarantees stronger than simple marginal coverage guarantees.

description: We present a fine-structure entanglement classification under stochastic local operation and classical communication (SLOCC) for multiqubit pure states. To this end, we employ specific algebraic-geometry tools that are SLOCC invariants, secant varieties, to show that for $n$-qubit systems there are $\lceil\frac{2^{n}}{n+1}\rceil$ entanglement families. By using another invariant, $\ell$-multilinear ranks, each family can be further split into a finite number of subfamilies. Not only does this method facilitate the classification of multipartite entanglement, but it also turns out to be operationally meaningful as it quantifies entanglement as a resource.

description: The two component Monte-Carlo Glauber model predicts a knee-like structure in the centrality dependence of elliptic flow $v_2$ in Uranium+Uranium collisions at $\sqrt{s_{NN}}=193$ GeV. It also produces a strong anti-correlation between $v_2$ and $dN_{ch}/dy$ in the case of top ZDC events. However, none of these features have been observed in data. We address these discrepancies by including the effect of nucleon shadowing to the two component Monte-Carlo Glauber model. Apart from addressing successfully the above issues, we find that the nucleon shadow suppresses the event by event fluctuation of various quantities, e.g. $\varepsilon_2$ which is in accordance with expectation from the dynamical models of initial condition based on gluon saturation physics.

New Classes of Conservation Laws Based on Generalized Fluid Densities and Reynolds Transport Theorems

Year: 2021
Subjects: subject: Fluid Dynamics (physics.flu-dyn)
subject: FOS: Physical sciences

description: The Reynolds transport theorem occupies a central place in fluid dynamics, providing a generalized integral conservation equation for the transport of any conserved quantity within a fluid, and connected to its corresponding differential equation. Recently, a new generalized framework was presented for this theorem, enabling parametric transformations between positions on a manifold or in a generalized coordinate space, exploiting the underlying multivariate Lie symmetries associated with a conserved quantity. We examine the implications of this framework for fluid flow systems, within an Eulerian position-velocity (phase space) description. The analysis invokes a hierarchy of five probability density functions, which by convolution are used to define five fluid densities and generalized densities appropriate for different spaces. We obtain 11 formulations of the generalized Reynolds transport theorem for different choices of the coordinate space, parameter space and density, only the first of which is known. These are used to generate 11 tables of integral and differential conservation laws applicable to these systems, for eight important conserved quantities (fluid mass, species mass, linear momentum, angular momentum, energy, charge, entropy and probability). These substantially expand the set of conservation laws for the analysis of fluid flow and dynamical systems.

description: Abstract Background: Quality data and appropriate information utilization are vital for the effective management of community-level health programs and interventions. In Ethiopia, the Community Health Information System (CHIS) has been implemented since 2012. However, little evidence exists regarding its implementation status. In Tiro Afata Woreda, southwest Ethiopia, this study sought to examine the factors that contribute to and hinder the adoption of a community health information system. Methods: A mixed-methods design was used to conduct the study from March to April 2021 in 19 health posts (HPs), where key informant interviews were undertaken with 21 purposefully selected health extension workers. Based on the Performance of Routine Information System Management (PRISM) concept, a quantitative questionnaire was created. Descriptive statistics were used to analyze quantitative data, and an index was computed for the implementation status of CHIS. Thematic analysis was performed on qualitative data. Results: A family folder was available in 13/19 HPs, integrated maternal and child health care in 15/19 HPs, and a family health card in 14/19 HPs. Overall, 6/19 HPs had folders, health cards, a field book, and a master family index, and 3/19 HPs had all the recommended tally sheets and CHIS tools. Fifteen out of nineteen HPs had shelves, 16/19 had tickler file boxes, and 14/19 had at least one trained health worker on data management and use. One out of nineteen HPs had properly practiced data quality reviews, and only two of the examined indicators (measles <1 year’s coverage and under-five pneumonia cases diagnosed) out of five have met an accuracy target (verification factor: 0.9–1.1). Sixteen out of nineteen HPs have submitted reports on time. None of the HPs has practiced performance reviews, and only three out of the 19 HPs have prepared recommended data visualizations. Moreover, only 6/19 HPs have used routine data for planning. A shortage of health workers, overburdened tasks, a lack of supportive supervision and supply of tools, and language barriers (English) in completing tools are hurdles in implementing CHIS. Conclusions: The performance of the CHIS was generally low. Data quality and information utilization were below the national target. Therefore, it is required that data management tools be supplied, supportive supervision must be strengthened, and data management tools must be produced in local languages for user convenience.

description: The stochastic thermodynamics of a dilute, well-stirred mixture of chemically-reacting species is built on the stochastic trajectories of reaction events obtained from the Chemical Master Equation. However, when the molecular populations are large, the discrete Chemical Master Equation can be approximated with a continuous diffusion process, like the Chemical Langevin Equation or Low Noise Approximation. In this paper, we investigate to what extent these diffusion approximations inherit the stochastic thermodynamics of the Chemical Master Equation. We find that a stochastic-thermodynamic description is only valid at a detailed-balanced, equilibrium steady state. Away from equilibrium, where there is no consistent stochastic thermodynamics, we show that one can still use the diffusive solutions to approximate the underlying thermodynamics of the Chemical Master Equation.

description: The COBRA collaboration operates a demonstrator setup at the underground facility LNGS (Laboratori Nazionali del Gran Sasso, located in Italy) to prove the technological capabilities of this concept for the search for neutrinoless double beta-decay. The setup consists of 64 $(1\times\!1\times\!1)$ cm$^{3}$ CZT detectors in CPG configuration. One purpose of this demonstrator is to test if reliable long-term operation of CZT-CPG detectors in such a setup is possible. The demonstrator has been operated under ultra low-background conditions since more than three years and collected data corresponding to an exposure of 218 kg$\cdot$days. The presented study focuses on the long-term stability of CZT detectors by analyzing the intrinsic, fourfold forbidden non-unique $^{113}$Cd single beta-decay. It can be shown that CZT detectors can be operated stably for long periods of time and that the $^{113}$Cd single beta-decay can be used as an internal monitor of the detector performance during the runtime of the experiment.

description: In this paper, we consider a generalization of percolation: percolation of three related fluids on a honeycomb lattice. K. Izyurov and A. Magazinov proved that percolations of distinct fluids between opposite sides on a fixed hexagon become mutually independent as the lattice step tends to 0. This paper exposes this proof in details (with minor simplifications) for nonspecialists. In addition, we state a few related conjectures based on numerical experiments.

description: Path integrals with complex actions are encountered for many physical systems ranging from spin- or mass-imbalanced atomic gases and graphene to quantum chromo-dynamics at finite density to the non-equilibrium evolution of quantum systems. Many computational approaches have been developed for tackling the sign problem emerging for complex actions. Among these, complex Langevin dynamics has the appeal of general applicability. One of its key challenges is the potential convergence of the dynamics to unphysical fixed points. The statistical sampling process at such a fixed point is not based on the physical action and hence leads to wrong predictions. Moreover, its unphysical nature is hard to detect due to the implicit nature of the process. In the present work we set up a general approach based on a Markov chain Monte Carlo scheme in an extended state space. In this approach we derive an explicit real sampling process for generalized complex Langevin dynamics. Subject to a set of constraints, this sampling process is the physical one. These constraints originate from the detailed-balance equations satisfied by the Monte Carlo scheme. This allows us to re-derive complex Langevin dynamics from a new perspective and establishes a framework for the explicit construction of new sampling schemes for complex actions.

description: This is a companion paper of arXiv:1909.11492. We prove an equivalence relating representations of a degenerate orthosymplectic supergroup with the category of $SO(N-1,{\mathbb C}[\![t]\!])$-equivariant perverse sheaves on the affine Grassmannian of $SO_N$. We explain how this equivalence fits into a more general framework of conjectures due to Gaiotto and to Ben-Zvi, Sakellaridis and Venkatesh.

Quantum polynomial functors

Year: 2017

description: Abstract We construct a category of quantum polynomial functors which deforms Friedlander and Suslin's category of strict polynomial functors. The main aim of this paper is to develop from first principles the basic structural properties of this category (duality, projective generators, braiding etc.) in analogy with classical strict polynomial functors. We then apply the work of Hashimoto and Hayashi in this context to construct quantum Schur/Weyl functors, and use this to provide new and easy derivations of quantum (GLm,GLn) duality, along with other results in quantum invariant theory.

description: We formulate the Hartree-Fock method using a functional integral approach. Then we consider a nonperturbative component of the vacuum polarization. For the Dirac-Coulomb operator the renormalization flow of the vacuum polarization is calculated numerically. For the Hartree-Fock operator the polarization is obtained by integrating an appropriately rescaled flow. The text includes an approximate calculation of the vacuum polarization in Uranium.

Switching from a continuous to discontinuous phase transition under the quenched disorder

description: Discontinuous phase transitions occurs to be particularly interesting from a social point of view because of their relationship to social hysteresis and critical mass. In this paper, we show that the replacement of a time-varying (annealed, situation-based) disorder by a static (quenched, personality-based) one can lead to a change from a continuous to a discontinuous phase transition. This is a result beyond the state of art, because so far numerous studies on various complex systems (physical, biological and social) have indicated that the quenched disorder can round or destroy the existence of a discontinuous phase transition. To show the possibility of the opposite behavior, we study a multistate $q$-voter model, with two types of disorder related to random competing interactions (conformity and anticonformity). We confirm, both analytically and through Monte Carlo simulations, that indeed discontinuous phase transitions can be induced by a static disorder.

description: We study Chebyshev filter diagonalization as a tool for the computation of many interior eigenvalues of very large sparse symmetric matrices. In this technique the subspace projection onto the target space of wanted eigenvectors is approximated with filter polynomials obtained from Chebyshev expansions of window functions. After the discussion of the conceptual foundations of Chebyshev filter diagonalization we analyze the impact of the choice of the damping kernel, search space size, and filter polynomial degree on the computational accuracy and effort, before we describe the necessary steps towards a parallel high-performance implementation. Because Chebyshev filter diagonalization avoids the need for matrix inversion it can deal with matrices and problem sizes that are presently not accessible with rational function methods based on direct or iterative linear solvers. To demonstrate the potential of Chebyshev filter diagonalization for large-scale problems of this kind we include as an example the computation of the $10^2$ innermost eigenpairs of a topological insulator matrix with dimension $10^9$ derived from quantum physics applications.

GMA: A Pareto Optimal Distributed Resource-Allocation Algorithm

description: To address the rising demand for strong packet delivery guarantees in networking, we study a novel way to perform graph resource allocation. We first introduce allocation graphs, in which nodes can independently set local resource limits based on physical constraints or policy decisions. In this scenario we formalize the distributed path-allocation (PAdist) problem, which consists in allocating resources to paths considering only local on-path information -- importantly, not knowing which other paths could have an allocation -- while at the same time achieving the global property of never exceeding available resources. Our core contribution, the global myopic allocation (GMA) algorithm, is a solution to this problem. We prove that GMA can compute unconditional allocations for all paths on a graph, while never over-allocating resources. Further, we prove that GMA is Pareto optimal with respect to the allocation size, and it has linear complexity in the input size. Finally, we show with simulations that this theoretical result could be indeed applied to practical scenarios, as the resulting path allocations are large enough to fit the requirements of practically relevant applications.
