Dynamics of Meandering Spiral Waves with Weak Lattice Perturbations

description: Re-entrant spiral waves are observed in many different situations in nature, perhaps most importantly in excitable electrophysiological tissue where they are believed to be responsible for pathological conditions such as cardiac arrhythmias, epileptic seizures, and hallucinations. Mathematically, spiral waves occur as solutions to systems of reaction-diffusion partial di erential equations (RDPDEs), which are frequently used as models for electrophysiological phenomena. Because of the invariance of these RDPDEs with respect to the Euclidean group SE(2) of planar translations and rotations, much progress has been made in understanding the dynamics and bifurcations of spiral waves using the theory of group-equivariant dynamical systems. In reality, however, Euclidean symmetry is at best an approximation. Inhomogeneities and anisotropy in the medium of propagation of the waves break the Euclidean symmetry and can lead to such phenomena as anchoring and drifting. In this paper, we study the effects on quasi-periodic meandering spiral waves of a small perturbation which breaks the continuous SE(2) symmetry but preserves the symmetry of a regular square lattice.

Analysis of axisymmetric boundary layers

Publisher: name: arXiv

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

description: Axisymmetric boundary layers are studied using integral analysis of the governing equations for axial flow over a circular cylinder. The analysis includes the effect of pressure gradient and focuses on the effect of transverse curvature on boundary layer parameters such as shape factor ($H$) and skin-friction coefficient ($C_f$), defined as $H = δ^*/θ$ and $C_f = τ_w/(0.5ρU_e^2)$ respectively, where $δ^*$ is displacement thickness, $θ$ is momentum thickness, $τ_w$ is the shear stress at the wall, $ρ$ is density and $U_e$ is the streamwise velocity at the edge of the boundary layer. Relations are obtained relating the mean wall-normal velocity at the edge of the boundary layer ($V_e$) and $C_f$ to the boundary layer and pressure gradient parameters. The analytical relations reduce to established results for planar boundary layers in the limit of infinite radius of curvature. The relations are used to obtain $C_f$ which shows good agreement with the data reported in the literature. The analytical results are used to discuss different flow regimes of axisymmetric boundary layers in the presence of pressure gradients.

Year: 2006
Subjects: subject: Probability
subject: Statistics
subject: FOS: Mathematics

description: A dynamic sampling plan among strata is a permutation of sampled items specifying which stratum is to receive the next item to be included in the sample. An optimal such plan has the property of achieving minimum variance for its cost whenever it is truncated. This article shows that optimal dynamic sampling plans exist under very general conditions, and gives a simple algorithm for constructing them. The well-known Neyman allocation is compared to the dynamic optimum, both statically and dynamically. The theorems rely on a version of the Neyman-Pearson Lemma adapted for use in search theory.

description: Consider a two-class classification problem when the number of features is much larger than the sample size. The features are masked by Gaussian noise with zero means and a covariance matrix !, where the precision matrix Ω = Σ−1 is unknown but is presumably sparse. The useful features, also unknown, are sparse and each contributes weakly (i.e., rare and weak) to the classification decision. By obtaining a reasonably good estimate of Ω, we formulate the setting as a linear regression model. We propose a two-stage classification method where we first select features by the method of Innovated Thresholding (IT), and then use the retained features and Fisher’s LDA for classification. In this approach, a crucial problem is how to set the threshold of IT.We approach this problem by adapting the recent innovation of Higher Criticism Thresholding (HCT). We find that when useful features are rare and weak, the limiting behavior of HCT is essentially just as good as the limiting behavior of ideal threshold, the threshold one would choose if the underlying distribution of the signals is known (if only!). Somewhat surprisingly, when " is sufficiently sparse, its off-diagonal coordinates usually do not have a major influence over the classification decision. Compared to recent work in the case where Ω is the identity matrix [15, 16], the current setting is much more general, which needs a new approach and much more sophisticated analysis. One key component of the analysis is the intimate relationship between HCT and Fisher’s separation. Another key component is the tight large deviation bounds for empirical processes associated with data with sparse but unconventional correlation structure, where the separability of sparse graphs plays an important role.

description: Inoculation with exogenous microbial agents is a common method to promote organic waste degradation and improve the quality of compost. However, the biotic effects of different microbial agents are often quite different. To evaluate the potential effects of a complex bacterial agent comprised of three strains (belonging to Bacillus and Geobacillus) on lignocellulose degradation and the underlying microbial mechanisms during cow dung composting, two lab-scale composting experiments, a control and a bacterial inoculation treatment, were established. The results suggest that bacterial inoculation accelerated the rate of temperature increase and extended the thermophilic phase. Compared to those in the negative control group, cellulose, hemicellulose, and lignin degradation rates in the inoculated group increased from 53.3% to 70.0%, 50.2% to 61.3%, and 46.4% to 60.0%, respectively. The microbial community structure and diversity in the compost were clearly changed by the bacterial inoculation. Moreover, stamp analysis showed that inoculation modulated the key compost microbial functional populations linked to the degradation of lignocellulose. Correlation matrix analysis indicated that the expression of bacterial lignocellulolytic enzymes is closely related to key microbial functional populations. Overall, the results confirm the importance of bacterial inoculation, and have important implications for promoting the efficiency and quality of cow dung compost. The effects of three Bacillus and Geobacillus strains on compost were established.Adding the complex bacterial agent increased the thermophilic phase.Inoculation promoted the abundance of key lignocellulose-degrading microbes.These findings will help promote the efficiency and quality of cow dung compost.

Optimal Challenges for Selection

description: This paper generalizes the problems of optimal selection considered by Roth, Kadane and DeGroot by allowing a set of J items to be chosen by two decision makers, the first of whom has A challenges and the second has B challenges. The two decision makers each have an opportunity to challenge each item before it is accepted, in some arbitrary fixed order. We assume that the decision makers know the utility function of the other side as well as their own over sets of J items, and that they know the subjective distribution, assigned by the other side, of characteristics of potential items that will be observed, as well as their own. Under these conditions the other side's response to each potential item can be predicted with certainty, and backward induction defines an optimal strategy. We study an important special case we call regular, and show that it is never disadvantageous to go first in the regular case. The use of peremptory challenges in jury trials motivates our model. The basic model in which jurors are challenged one at a time is extended to a more general class of problems that includes the group system and the struck jury system.

description: The elements (squared) of the neutrino mixing matrix are found to satisfy, as functions of the induced mass, a set of differential equations. They show clearly the dominance of pole terms when the neutrino masses "cross". Using the known vacuum mixing parameters as initial conditions, it is found that these equations have very good approximate solutions, for all values of the induced mass. The results are applicable to Long Baseline Experiments (LBL).

Climate Change, Forced Labour, and the International Labour Organization in Cambodia: Disentangling Decent Work, Economic Growth, and Environmental Damage
Creators: name: Kozlowski, Sonia
Publisher: name: My University
Year: 2021

description: This paper contributes to the gap in current research surrounding the reinforcing relationship between climate change, exploitative labour, and environmental damage by analyzing bonded labour in Cambodian brickwork. Relying on the Marxist theory of labour exploitation, this paper highlights how structural economic changes contributed to agricultural dispossession and increased vulnerability among Cambodian smallholders to indebtedness and debt bondage. Relatedly, this paper analyzes the International Labour Organization as a hegemonic actor through a neo-Gramscian framework to highlight how its Decent Work Agenda and Decent Work Country Programmes are unlikely to eradicate forced labour. On these bases, it makes two independent yet interrelated contributions. First, forced labour in Cambodia is intimately linked to agrarian insecurity, driven by neoliberal economic reforms and anthropogenic climate change, and causes further local environmental degradation. Second, the International Labour Organization’s Decent Work Agenda and Decent Work Country Programme are doubly ineffective in eradicating forced labour due to inconsistencies between their ideological assumptions and goals. In light of its findings, this paper advances recommendations for the Royal Government of Cambodia and the International Labour Organization, including decoupling environmentally sustainable and decent work from expectations of economic growth. Keywords: brickwork, Cambodia, climate change, environmental damage, forced labour, International Labour Organization.

description: We explore the coherent thermal transport sustained by solitons through a long Josephson junction, as a thermal gradient across the system is established. We observe that a soliton causes the heat current through the system to increase. Correspondingly, the junction warms up in correspondence of the soliton, with temperature peaks up to, e.g., approximately 56 mK for a realistic Nb-based proposed setup at a bath temperature Tbath = 4.2 K. The thermal effects on the dynamics of the soliton are also discussed. Markedly, this system inherits the topological robustness of the solitons. In view of these results, the proposed device can effectively find an application as a superconducting thermal router in which the thermal transport can be locally mastered through solitonic excitations, which positions can be externally controlled through a magnetic field and a bias current.

description: The behavior of quasi-local black hole horizons in a binary black hole merger is studied numerically. We compute the horizon multipole moments, fluxes and other quantities on black hole horizons throughout the merger. These lead to a better qualitative and quantitative understanding of the coalescence of two black holes; how the final black hole is formed, initially grows and then settles down to a Kerr black hole. We calculate the rate at which the final black hole approaches equilibrium in a fully non-perturbative situation and identify a time at which the linear ringdown phase begins. Finally, we provide additional support for the conjecture that fields at the horizon are correlated with fields in the wave-zone by comparing the in-falling gravitational wave flux at the horizon to the outgoing flux as estimated from the gravitational waveform.

description: In this article, we demonstrate that the unexpected peak at around $95 \, {\rm GeV}$ as seen recently by CMS in the di-photon final state can be explained within the type-I~two-Higgs-doublet model by means of a moderately-to-strongly fermiophobic CP-even Higgs $H$. Depending on the Higgs mass spectrum, the production of such~a~$H$ arises dominantly from vector boson fusion or through a cascade in either $pp \to t \bar t$ with $\overset{(-)}{t} \to H^{\pm} \overset{(-)}{b} \to W^{\pm \, \ast} H \overset{(-)}{b}$ or $pp \to A$ with $A \to W^{\mp} H^{\pm} \to W^{\mp} W^{\pm} H$ or via $pp \to W^{\pm \, \ast} \to H^\pm H$. In this context, we also discuss other Higgs anomalies such as the LEP excess in Higgsstrahlung and the observation of enhanced rates in $t \bar t h$ at both the Tevatron and the LHC, showing that parameters capable of explaining the CMS di-photon signal can address the latter deviations as well. The Higgs spectra that we explore comprise masses between $80 \, {\rm GeV}$ and $350\, {\rm GeV}$. While at present all constraints from direct and indirect searches for spin-0 resonances can be shown to be satisfied for such light Higgses, future LHC data will be able to probe the parameter space that leads to a simultaneous explanation of the discussed anomalies.

Year: 2020

description: This paper researches superstar player effects on the announced attendance and the probability of a sellout in the Ontario Hockey League for the 2011-2012 to the 2019-2020 regular seasons. Using a rich panel data set of game-level information, I find superstar players have a significant positive effect on the attendance of regular season games. Superstar players are also found to have an economically significant impact on the probability of a sellout, but this latter result is in most cases statistically insignificant. Finally, the superstar effect for sellouts and attendance are seen to change depending on the definition of a superstar, and also if the superstar plays on the home or away team.

description: A characterization is given of diametrically opposed interests between two players: either neither is a Bayesian, or both have a unique probability and utility function (up to the usual transformation) or both have many possible probabilities and utilities. In the second case, their utility functions must have representations that sum to zero, and they must have identical probability distributions on every uncertain event in the space. Implications of this result for negotiations and for game theory are discussed

description: BaPb$_{1-x}$Bi$_x$O$_3$ is a superconductor, with transition temperature $T_c=11$ K, whose parent compound BaBiO$_3$ possess a charge ordering phase and perovskite crystal structure reminiscent of the cuprates. The lack of magnetism simplifies the BaPb$_{1-x}$Bi$_{x}$O$_3$ phase diagram, making this system an ideal platform for contrasting high-$T_c$ systems with isotropic superconductors. Here we use high-quality epitaxial thin films and magnetotransport to demonstrate superconducting fluctuations that extend well beyond $T_c$. For the thickest films (thickness above $\sim100$ nm) this region extends to $\sim27$ K, well above the bulk $T_c$ and remarkably close to the higher $T_c$ of Ba$_{1-x}$K$_x$BiO$_3$ ($T_c=31$ K). We drive the system through a superconductor-insulator transition by decreasing thickness and find the observed $T_c$ correlates strongly with disorder. This material manifests strong fluctuations across a wide range of thicknesses, temperatures, and disorder presenting new opportunities for understanding the precursor of superconductivity near the 2D-3D dimensionality crossover.

description: El régimen actual de protección de los usuarios del transporte aéreo en Colombia contiene gran cantidad de normas que delimitan las funciones administrativas y jurisdiccionales de las autoridades colombianas, dirigidas a proteger y promover los derechos y deberes de los consumidores. Sin embargo, el marco jurídico vigente parece proporcionar tan sólo una protección formal más no sustancial. En tanto, la dispersión normativa en el ordenamiento jurídico colombiano dificulta al usuario determinar el escenario ideal para la protección efectiva sus derechos. Esta monografía analiza y propone alternativas que permitan superar los obstáculos que enfrentan los usuarios del transporte aéreo de pasajeros en Colombia frente al ejercicio de sus derechos. Ya que, además de ser un servicio público esencial según el artículo 68 de la Ley 336 de 1996, emana del derecho fundamental a la libre circulación consagrado en el artículo 24 de la Constitución Política de Colombia y la prestación deficiente del servicio puede afectar a millones de usuarios que se movilizan por este modo. Así, resulta importante poner de presente que la protección prevista no puede limitarse a un reconocimiento normativo (de derechos, deberes, autoridades y procedimientos) sino que debe conllevar la efectiva salvaguarda de los derechos de los usuarios.
description: The current regime for the protection of air transport users in Colombia contains a large number of rules that narrow the administrative and jurisdictional functions of the Colombian authorities, aimed at protecting and promoting the rights and duties of consumers. However, the current legal framework seems to provide only formal but not substantial protection. The dispersion of regulations in the Colombian legal system makes it difficult for the user to determine the ideal scenario for the effective protection of its rights. This monograph analyzes and proposes alternatives to overcome the obstacles faced by users of air passenger transportation in Colombia for enforcing their rights. In addition to being an essential public service according to Article 68 of Law 336 of 1996, it emanates from the fundamental right to freedom of movement enshrined in Article 24 of the Political Constitution of Colombia, and the deficient provision of the service may affect millions of users who use this mode of transportation. Thus, it is important to point out that the protection provided for cannot be limited to a normative recognition (of rights, duties, authorities, and procedures) but must entail the effective safeguarding of the rights of users.

description: Los profundos cambios en la interacción social, en los postulados y límites de la acción estatal, en la distribución de las riquezas y pobrezas, y, en general, en la experiencia de la cotidianidad producidos desde 2020 por la pandemia del COVID-19 hacen necesarias reflexiones interdisciplinarias y lecturas comparadas para entender lo que estamos viviendo y arriesgar ideas sobre el porvenir. Este momento histórico nos ubica en un punto de observación privilegiado para evaluar y proyectar nuevos modos de organización y comunicación colectiva que, entre otras cosas, implican diferentes formas de relacionarnos con los pasados, con el valor que les atribuimos, con la forma como los conservamos y exhibimos, con los usos que les damos y, en general, con el tipo de relaciones que componemos a partir de ellos. En este contexto, diversas prácticas disciplinares han adoptado enfoques, metodologías y modos de codificación novedosos para mantenerse al tanto de lo que dichos cambios implican. Las humanidades digitales atraviesan un momento de auge y, consecuentemente, sus objetos de reflexión, fuentes de consulta y modos de transmitir conclusiones proponen nuevos horizontes de trabajo. Por otra parte, cada vez son más los museos latinoamericanos que han desarrollado iniciativas, programas y enfoques dedicados a promover la relectura de sus colecciones y la participación e inclusión de sujetos, públicos y audiencias. Finalmente, la historia pública poco a poco ha encontrado un momento de consolidación a través de la explosión de un sinfín de proyectos creativos que retan las formas tradicionales de apropiación del pasado.

description: We investigate the effects of AGN feedback on the cosmological evolution of an isolated elliptical galaxy by performing two-dimensional high-resolution hydrodynamical numerical simulations. The inner boundary of the simulation is chosen so that the Bondi radius is resolved. Compared to previous works, the two accretion modes, namely hot and cold, which correspond to different accretion rates and have different radiation and wind outputs, are carefully discriminated and the feedback effects by radiation and wind in each mode are taken into account. The most updated AGN physics, including the descriptions of radiation and wind from the hot accretion flows and wind from cold accretion disks, are adopted. Physical processes like star formation, Type Ia and Type II supernovae are taken into account. We study the AGN light curve, typical AGN lifetime, growth of the black hole mass, AGN duty-cycle, star formation, and the X-ray surface brightness of the galaxy. We compare our simulation results with observations and find general consistency. Comparisons with previous simulation works find significant differences, indicating the importance of AGN physics. The respective roles of radiation and wind feedbacks are examined and it is found that they are different for different problems of interest such as AGN luminosity and star formation. We find that it is hard to neglect any of them, so we suggest to use the names of "cold feedback mode" and "hot feedback mode" to replace the currently used ones.

description: In this paper we consider the problem of grouped variable selection in high-dimensional regression using ℓ1-ℓq regularization (1 ≤ q ≤ ∞), which can be viewed as a natural generalization of the ℓ1-ℓ2 regularization (the group Lasso). The key condition is that the dimensionality pn can increase much faster than the sample size n, i.e. pn >> n (in our case pn is the number of groups), but the number of relevant groups is small. The main conclusion is that many good properties from ℓ1-regularization (Lasso) naturally carry on to the ℓ1-ℓq cases (1 ≤ q ≤ ∞), even if the number of variables within each group also increases with the sample size. With fixed design, we show that the whole family of estimators are both estimation consistent and variable selection consistent under different conditions. We also show the persistency result with random design under a much weaker condition. These results provide a unified treatment for the whole family of estimators ranging from q = 1 (Lasso) to q = ∞ (iCAP), with q = 2 (group Lasso)as a special case. When there is no group structure available, all the analysis reduces to the current results of the Lasso estimator (q = 1).

description: Teachers make hundreds of critical decisions each school day. Educators decide which curriculum to adopt, how to support struggling learners, what to do about students with behavioral challenges, how to teach, and how and when to adjust lessons. The most effective choices are those made using the best available evidence. In recent years, the evidence-based practice movement has raised questions about what makes up a practical, evidence-based approach.
Rethinking Max Weber’s Study of Chinese Religions in a Modern Scope

description: On November 11, 2018, China’s annual online shopping festival Singles’ Day hit 213.5 billion RMB (approximately 30.8 billion USD) in sales within 24 hours (Chong, 2018), increasing by 27% compared to 2017 (Davidson, 2018). This whopping number is much bigger than Black Friday and Cyber Monday combined (Chong, 2018). On a worldwide scale, Singles’ Day can be seen as the biggest capitalistic event that happened online; however, to witness the upheaval of Singles’ Day was an illusion tracking back to Max Weber’s time during the 1910s. In the book The Religion of China: Confucianism and Taoism that was published in 1915, Weber asserted that capitalism cannot grow in China due to its irrational religious ethics. Taking on this conflict, a review of Weber’s studies on Chinese religions will be drawn into account to evaluate Weber’s findings’ in a modern scope through an examination of “ideal types” of three dominant religions in China including Confucianism, Taoism and Buddhism. The discussion will be guided by the research question: Do Weber’s studies of religious ethics of Chinese religions still apply in modern China after the 20th century? Document analysis will be employed as the research method to help unpack issues we encounter by following this research question as it pertains to Weber’s book The Religion of China: Confucianism and Taoism. Keywords: Max Weber; Chinese religions; religious ethics; modern capitalism, Confucianism; Taoism; Buddhism; ideal types

description: Higher-order perturbative calculations in Quantum (Field) Theory suffer from the factorial increase of the number of individual diagrams. Here I describe an approach which evaluates the total contribution numerically for finite temperature from the cumulant expansion of the corresponding observable followed by an extrapolation to zero temperature. This method (originally proposed by Bogolyubov and Plechko) is applied to the calculation of higher-order terms for the ground-state energy of the polaron. Using state-of-the-art multidimensional integration routines 2 new coefficients are obtained corresponding to a 4- and 5-loop calculation.

description: A modifed Faddeev-Popov path integral density for the quantization of Yang-Mills theory in the Feynman gauge is discussed, where contributions of the Faddeev-Popov ghost fields are replaced by multi-point gauge field interactions. An explicit calculation to $O(g^2)$ shows the equivalence of the usual Faddeev-Popov scheme and its modified version.

description: Graphene as well as more generally Dirac solids constitute two dimensional materials where the electronic flow is ultra relativistic. When a Dirac solid is deposited on a different substrate surface with roughness, a local random potential develops through an inhomogeneous charge impurity distribution. This external potential affects profoundly the charge flow and induces a chaotic pattern of current branches that develops through focusing and defocusing effects produced by the randomness of the surface. An additional bias voltage may be used to tune the branching pattern of the charge carrier currents. We employ analytical and numerical techniques in order to investigate the onset and the statistical properties of carrier branches in Dirac solids. We find a specific scaling-type relationship that connects the physical scale for the occurrence of branches with the characteristic medium properties, such as disorder and bias field. We use numerics to test and verify the theoretical prediction as well as a perturbative approach that gives a clear indication of the regime of validity of the approach. This work is relevant to device applications and may be tested experimentally.

description: El trigo es un producto universal que se siembra en casi todo el mundo, bien llamado commoditie el cual se comercializa para hacer otros productos derivados. Actualmente Venezuela no cuenta con la capacidad suficiente para producir el trigo necesario para cubrir la demanda, así que importa de diferentes países como Canadá, estados Unidos, Rusia y Ucrania con bajos aranceles. La producción mundial de trigo para el año 2022 alcanzó 781,2 millones de toneladas, en Europa, se estima una disminución del 40% en la producción de Ucrania dado el conflicto con Rusia, donde según la División de Estadísticas de la Organización de Naciones Unidas, Rusia en 2020 exportó el 37,3% del trigo a escala mundial y Ucrania 18,1%. Para los demás países como Estados Unidos, los factores climáticos alteraron los precios en el mercado por la ola invernal (Organizacion de las naciones unidas para la alimentacion y la agricultura, 2022).

description: Despite substantial interest in the role of energy in the economy, the degree of substitutability between energy and other production inputs, and the way energy should be included in the production function remain unresolved issues. Our study provides industry-level parameter estimates of two-level constant elasticity of substitution (CES) functions that include capital, labour and energy inputs and allow for technological change for Canada. In contrast to many existing studies, we do not impose prior restrictions on the order of input nesting, and we report the estimates for three possible specifications. We find that a nested production structure which first combines labour and energy into a composite good that is then combined with capital, fits the Canadian data best, in terms of respecting the restrictions imposed by cost minimization. We also find rather low elasticities of substitution between capital and labour, and limited evidence of exogenous technological change. / Malgré l'intérêt considérable par rapport au rôle de l'énergie dans l'économie, le degré de substituabilité entre l'énergie et autres facteurs de production, et la façon dont l'énergie devrait être introduite dans la fonction de production restent des questions non résolues. Notre étude fournit, pour le Canada, des estimations sectorielles des élasticités de substitution de fonctions de production de type CES emboîtées à deux niveaux, qui combinent le capital, le travail et l'énergie, et qui prennent en compte le changement technologique. Contrairement à de nombreuses études existantes, nous n'imposons pas de restrictions a priori sur l’ordre de l’emboîtement dans les fonctions CES, et nous présentons les estimations pour les trois spécifications possibles. Nous avons trouvé qu'une structure de production imbriquée qui allie le travail et l'énergie dans un facteur composite, qui est ensuite combiné avec le capital, correspond mieux aux données canadiennes, en ce qui a trait au respect des restrictions imposées par la minimisation des coûts. Nous avons également trouvé des élasticités de substitution relativement faibles entre le capital et le travail, et une très faible évidence pour un changement technologique exogène.
