description: Electric dipole moments are sensitive probes of new phases in the Higgs Yukawa couplings. We calculate the complete two-loop QCD anomalous dimension matrix for the mixing of CP-odd scalar and tensor operators and apply our results for a phenomenological study of CP violation in the bottom and charm Yukawa couplings. We find large shifts of the induced Wilson coefficients at next-to-leading-logarithmic order. Using the experimental bound on the electric dipole moment of the neutron, we update the constraints on CP-violating phases in the bottom and charm quark Yukawas.

Subjects: subject: High Energy Physics - Theory (hep-th)

description: The semiclassical solution of quantum Dirac constraints in generic constrained system is obtained by directly calculating in the one-loop approximation the gauge field path integral with relativistic gauge fixing procedure. The gauge independence property of this path integral is analyzed by the method of Ward identities with a special emphasis on boundary conditions for gauge fields. The calculations are based on the known reduction algorithms for functional determinants extended to gauge theories. The mechanism of transition from relativistic gauge conditions to unitary gauges, participating in the construction of this solution, is explicitly revealed. Implications of this result in problems with spacetime boundaries, quantum gravity and cosmology are briefly discussed.

description: We introduce the multivariate decomposition finite element method (MDFEM) for solving elliptic PDEs with uniform random diffusion coefficients. We show that the MDFEM can be used to reduce the computational complexity of estimating the expected value of a linear functional of the solution of the PDE. The proposed algorithm combines the multivariate decomposition method (MDM), to compute infinite dimensional integrals, with the finite element method (FEM), to solve different instances of the PDE. The strategy of the MDFEM is to decompose the infinite-dimensional problem into multiple finite-dimensional ones which lends itself to easier parallelization than to solve a single large dimensional problem. Our first result adjusts the analysis of the multivariate decomposition method to incorporate the log-factor which typically appears in error bounds for multivariate quadrature, i.e., cubature, methods; and we take care of the fact that the number of points $n$ needs to come, e.g., in powers of 2 for higher order approximations. For the further analysis we specialize the cubature methods to be two types of quasi-Monte Carlo (QMC) rules, being digitally shifted polynomial lattice rules and interlaced polynomial lattice rules. The second and main contribution then presents a bound on the error of the MDFEM and shows higher-order convergence w.r.t. the total computational cost in case of the interlaced polynomial lattice rules in combination with a higher-order finite element method.

Subjects: subject: South Asia

subject: Social vernacular
subject: Qawwali

description: This thesis describes the vernacular tradition of the dholki, a common wedding event with song and singing. The dholki is framed in a context of a male-dominated religious society and has the propensity to be utilized as a flexible vehicle for the dissemination of religious and spiritual thought, worship, or rulings. The process of writing this thesis started with ethnographic fieldwork in Lahore in the summer of 2021, where the author spoke to a variety of women at the Bibi Pak Daman shrine. This thesis places the dholki within the study of vernacular tradition in the Punjab and broader South Asia. Through a deconstruction of the event, its context, and the songs and beats that women utilize during the event, I argue that the dholki provides a flexible vehicle through which women are able to disseminate, adapt, permeate, and transform religiosity and spirituality.

description: Cet article s’interroge sur la manière dont l’épargne salariale peut être mobilisée pour constituer un portefeuille d’investissement à long terme. Pour ce faire, nous y effectuons une clarification conceptuelle des notions d’épargne salariale et de gestion de portefeuille d’investissement. À la suite d’une revue littéraire, nous formulons l’hypothèse selon laquelle la politique d’épargne salariale permet l’amélioration de la gestion de portefeuille et d’investissement à long terme. Pour vérifier cette hypothèse, nous avons mobilisé une base de données secondaires, principalement issues de la base de données de la DARES. Les analyses descriptives et de régressions qui s’en ont suivi ont été réalisées grâce au logiciel STATA v.14. Il en ressort que l’épargne salariale a une incidence sur la politique d’investissement d’une part, et que les investissements des sommes constituées en épargne salariale ont une incidence positive sur les dividendes d’autre part. Par conséquent, il est judicieux de mobiliser l’ES pour constituer un portefeuille d’investissement.

description: We construct the effective field theory of the Calogero-Sutherland model in the thermodynamic limit of large number of particles $N$. It is given by a $\winf$ conformal field theory (with central charge $c=1$) that describes {\it exactly} the spatial density fluctuations arising from the low-energy excitations about the Fermi surface. Our approach does not rely on the integrable character of the model, and indicates how to extend previous results to any order in powers of $1/N$. Moreover, the same effective theory can also be used to describe an entire universality class of $(1+1)$-dimensional fermionic systems beyond the Calogero-Sutherland model, that we identify with the class of {\it chiral Luttinger systems}. We also explain how a systematic bosonization procedure can be performed using the $\winf$ generators, and propose this algebraic approach to {\it classify} low-dimensional non-relativistic fermionic systems, given that all representations of $\winf$ are known. This approach has the appeal of being mathematically complete and physically intuitive, encoding the picture suggested by Luttinger's theorem.

description: Deep learning models have achieved remarkable success in natural language inference (NLI) tasks. While these models are widely explored, they are hard to interpret and it is often unclear how and why they actually work. In this paper, we take a step toward explaining such deep learning based models through a case study on a popular neural model for NLI. In particular, we propose to interpret the intermediate layers of NLI models by visualizing the saliency of attention and LSTM gating signals. We present several examples for which our methods are able to reveal interesting insights and identify the critical information contributing to the model decisions.

description: Using a density matrix approach to describe the process of coalescence, we calculate the coalescence probabilities and invariant momentum spectra for deuterons and antideuterons. We evaluate our expressions with a hydrodynamically motivated parametrization for the source at freeze-out which implements rapid collective expansion of the collision zone formed in heavy ion collisions. We find that the coalescence process is governed by the same lengths of homogeneity which can be extracted from HBT interferometry. They appear in the absolute cluster yield via an effective volume factor as well as in a quantum mechanical correction factor which accounts for the internal structure of the deuteron cluster. Our analysis provides a new interpretation for the parameters in the popular phenomenological coalescence model and for the effective overlap volume in Hagedorn's model for cluster production in pp collisions. Using source parameters extracted from a recent HBT analysis of two-pion correlations, we successfully describe deuteron and antideuteron production data from Pb+Pb collisions at the CERN SPS as measured by the NA44 and NA52 collaborations. We also confirm the recent finding by Polleri et al. that the different measured slopes of nucleon and deuteron transverse mass spectra require a transverse density profile of the source which is closer to a box than to a Gaussian shape.

description: Non-alcoholic fatty liver disease (NAFLD) is a growing epidemic characterized by increased intrahepatic lipid accumulation. In some individuals, NAFLD progresses to non-alcoholic steatohepatitis (NASH), with complications including hepatocellular carcinoma and cirrhosis. As a rise in NAFLD cases has been associated with an increase in the consumption of high levels of fats and carbohydrates, also known as a high-caloric diet, and in obesity, understanding how dietary fatty acids contribute to the development of NAFLD through their effects on mitochondrial biogenesis and fatty acid oxidation may expand an array of potential therapeutics for the treatment of NAFLD. In this study, hepatocytes were treated with two concentrations (800uM and 250uM) of dietary fatty acids (oleic, palmitic, and butyric). These treatments resulted in changes in lipid accumulation, the ratio of mitochondrial to nuclear DNA, and the levels of expression of mRNAs involved in mitochondrial homeostasis and lipid processing. Interestingly, oleic and palmitic acids, although both classified as long-chain fatty acids, did not have the same effect on those cellular characteristics. Specifically, treatment with either 800uM or 250uM of oleic acid resulted in a decrease in CPT-1a expression, suggesting a decrease in mitochondrial fatty acid import. In comparison, treatment with 800uM palmitic acid resulted in a significant increase in CPT-1a expression, suggesting an increase in mitochondrial fatty acid import. Palmitic acid also induced increased expression of ACOX1 and MFn2 suggesting increased peroxisomal beta-oxidation and reorganization of the mitochondrial architecture. Exposure to a short chain fatty acid, butyrate, resulted in lipid accumulation, changes in expression pattern of genes involved in beta-oxidation, and no change in the ratio of mitochondrial to nuclear DNA. Overall, this study profiled the dynamic and complex responses of hepatocytes to exogenous free fatty acids. Differences in expression levels of genes involved in beta-oxidation brings some insight into a dynamic interplay of fatty acids, their breakdown by beta-oxidation, and transcriptional regulation in human hepatocytes in response to fatty acids.

description: A method of continual ZnO nanoparticle (NP) generation was tested for use in follow-up long-term inhalation exposure experiments with small laboratory animals. NPs were synthesized in an externally heated tube reactor by the evaporation of metallic zinc into a stream of nitrogen carrier gas, followed by the oxidation of zinc vapor in a stream of air and the formation of NPs by a chemical vapor condensation method. The NP production was studied at various evaporation temperatures, reactor flow rates and flow rates of mixing air. Particle generation for more than 100 h in two experimental runs with one batch of the zinc precursor was performed without a considerable decrease in the particle production rate. As a result, particle production with a number concentration much greater than 1.0 × 107 #/cm3, a mean particle/agglomerate size well below 50 nm and an emission rate greater than 5 μg/min was obtained under most of the investigated experimental conditions. A maximum emission rate of 16.3 μg/min was obtained at an evaporation temperature of 530 °C, a reactor flow rate of 800 cm3/min and a mixing flow rate of 2000 cm3/min and could be further increased by an increase in the evaporation temperature. The particle characteristics were studied, and estimates of the lung surface deposition area were calculated on the basis of the model developed by the International Commission of Radiological Protection.

description: A global analysis of all the available atmospheric neutrino data is presented in terms of neutrino oscillations in the nu_mu -> nu_tau and nu_mu -> nu_s channels, where nu_s denotes a sterile neutrino. We perform our analysis of the contained events data as well as the upward-going neutrino-induced muon fluxes. In addition to the previous data samples of Frejus, Nusex, IMB and Kamioka experiments, we include the full data set of the 52 kton-yr of Super-Kamiokande, the recent 4.6 kton-yr contained events of Soudan2 and the results on upgoing muons from the MACRO and Baksan detectors. From the statistical analysis it emerges that the nu_mu -> nu_tau channel provides the best agreement with the combined data, with a best fit point of sin^2(2 theta) = 0.99 and Delta m^2 = 3.0 * 10^{-3} eV^2. Although somehow disfavoured, the nu_mu -> nu_s channels cannot be ruled out on the basis of the global fit to the full set of observables.

Average Convergence Rate of Evolutionary Algorithms II: Continuous Optimization

description: The average convergence rate (ACR) measures how fast the approximation error of an evolutionary algorithm converges to zero per generation. It is defined as the geometric average of the reduction rate of the approximation error over consecutive generations. This paper makes a theoretical analysis of the ACR in continuous optimization. The obtained results are summarized as follows. According to the limit property, the ACR is classified into two categories: (1) linear ACR whose limit inferior value is larger than a positive and (2) sublinear ACR whose value converges to zero. Then, it is proven that the ACR is linear for evolutionary programming using positive landscape-adaptive mutation, but sublinear for that using landscape-invariant or zero landscape-adaptive mutation. The relationship between the ACR and the decision space dimension is also classified into two categories: (1) polynomial ACR whose value is larger than the reciprocal of a polynomial function of the dimension for any generation, and (2) exponential ACR whose value is less than the reciprocal of an exponential function of the dimension for an exponential long period. It is proven that for easy problems such as linear functions, the ACR of the (1+1) adaptive random univariate search is polynomial. But for hard functions such as the deceptive function, the ACR of both the (1+1) adaptive random univariate search and evolutionary programming is exponential.

description: The W-fusion scattering process W+W- --> ZZ for off-shell W bosons is studied, focusing on the issue of its high-energy behaviour which is known to be anomalous. It is shown that the unitarity violating terms can be isolated and extracted in a well-defined and efficient way using the pinch-technique. This restores the good high energy behaviour of the cross section and, in particular, makes possible the identification of the Higgs resonance in the invariant mass distribution M(ZZ) of the Z pair. The discarded terms, which are proportional to the off-shellness of the W bosons, cancel against similar terms originating from the remaining diagrams for the full physical process f1 f2 --> f1' f2' Z Z. This cancellation ensures the gauge invariance of our result, which therefore constitutes a meaningful separation between signal and background when they both contribute coherently. Equipped with this result, we are able to define a resonant approximation for the process p p --> Z Z + 2 jets + X, which circumvents the problem of good high energy behaviour without having to resort to the lengthy calculation of the complete set of diagrams. In this approximation only the W and Z fusion signal graphs are included, i.e. the ones which contain the Higgs resonance. We have verified that the approximate resonant cross section describes very well the full result not only close to the resonance but also beyond it.

description: The bulk properties (lattice constants, bulk moduli, and cohesive energies) of alkali, alkaline-earth, and transition metals are studied within the framework of the recently developed meta-GGA (meta-Generalized Gradient Approximation) semilocal exchange-correlation functionals. To establish the applicability, broadness and accuracy of meta-GGA functionals we also put the results of PBE (Perdew-Burke-Ernzerhof) and PBEsol (PBE reparametrized for solids) functionals. The interesting feature of the present paper is that it measures the accuracy of the recently developed TM (Tao-Mo) and TMTPSS (TM exchange with Tao-Perdew-Staroverov-Scuseria (TPSS) correlation) and SCAN (Strongly Constrained and Appropriately Normed) functionals on describing aforementioned properties. The present systematic investigation shows that the TM is accurate in describing the lattice constants while for cohesive energies and bulk moduli the accuracy is biased towards the PBE and TPSS functionals.

Hydrograph peak-shaving using a graph-theoretic algorithm for placement of hydraulic control structures

description: The need to attenuate hydrograph peaks is central to the design of stormwater and flood control systems. However, few guidelines exist for siting hydraulic control structures such that system-scale benefits are maximized. This study presents a graph-theoretic algorithm for stabilizing the hydrologic response of watersheds by placing controllers at strategic locations in the drainage network. This algorithm identifies subcatchments that dominate the peak of the hydrograph, and then finds the "cuts" in the drainage network that maximally isolate these subcatchments, thereby flattening the hydrologic response. Evaluating the performance of the algorithm through an ensemble of hydrodynamic simulations, we find that our controller placement algorithm produces consistently flatter discharges than randomized controller configurations---both in terms of the peak discharge and the overall variance of the hydrograph. By attenuating flashy flows, our algorithm provides a powerful methodology for mitigating flash floods, reducing erosion, and protecting aquatic ecosystems. More broadly, we show that controller placement exerts an important influence on the hydrologic response and demonstrate that analysis of drainage network structure can inform more effective stormwater control policies.

description: Using the mode-by-mode summation technique the zero point energy of the electromagnetic field is calculated for the boundary conditions given on the surface of an infinite solid cylinder. It is assumed that the dielectric and magnetic characteristics of the material which makes up the cylinder $(ε_1, μ_1)$ and of that which makes up the surroundings $(ε_2, μ_2)$ obey the relation $ε_1μ_1= ε_2μ_2$. With this assumption all the divergences cancel. The divergences are regulated by making use of zeta function techniques. Numerical calculations are carried out for a dilute dielectric cylinder and for a perfectly conducting cylindrical shell. The Casimir energy in the first case vanishes, and in the second is in complete agreement with that obtained by DeRaad and Milton who employed a Green's function technique with an ultraviolet regulator.

description: The complex transmission ecologies of vector-borne and zoonotic diseases pose challenges to their control, especially in changing landscapes. Human incidence of zoonotic malaria (Plasmodium knowlesi) is associated with deforestation although mechanisms are unknown. Here, a novel application of a method for predicting disease occurrence that combines machine learning and statistics is used to identify the key spatial scales that define the relationship between zoonotic malaria cases and environmental change. Using data from satellite imagery, a case–control study, and a cross-sectional survey, predictive models of household-level occurrence of P. knowlesi were fitted with 16 variables summarized at 11 spatial scales simultaneously. The method identified a strong and well-defined peak of predictive influence of the proportion of cleared land within 1 km of households on P. knowlesi occurrence. Aspect (1 and 2 km), slope (0.5 km) and canopy regrowth (0.5 km) were important at small scales. In contrast, fragmentation of deforested areas influenced P. knowlesi occurrence probability most strongly at large scales (4 and 5 km). The identification of these spatial scales narrows the field of plausible mechanisms that connect land use change and P. knowlesi, allowing for the refinement of disease occurrence predictions and the design of spatially-targeted interventions.

title: Leadership Transitions in Teams
Creators: name: (:Unkn) Unknown
Publisher: name: George Mason University
Year: 2021

description: Recent studies have shown that teams can benefit from informal rotated leadership structures in which leadership responsibilities are rapidly shifted from one individual to another (Aime et al., 2014). Teams can quickly adapt to changes in dynamic environments by engaging in functional leadership transitions where leadership responsibilities are transferred to the focal member whose expertise and resources are most critical for the team’s situation. The current dissertation utilizes social categorization and leader identity formation theories (DeRue & Ashford, 2010; Lord et al., 1987) to explain the process of how teams transition leadership. The interactions between two team mental models of leadership (i.e., heterarchical leader prototypes and transactive memory of leadership capacities), and two team member traits (i.e., motivation to lead and psychological collectivism), are examined as potential antecedents to functional leadership transitions in an experiment using a computer-based team decision making task. A between-teams experimental design was used to manipulate the two team mental models through two trainings. Results show a significant two-way interaction between mental models and a significant, but negative, three-way interaction between the two team mental models and psychological collectivism. Finally, while functional leadership transitions across time do not correlate with performance, post hoc analyses indicate that functional leadership transitions may be important for maximizing performance at the final stages of a team performance episode.

description: We give asymptotically converging semidefinite programming hierarchies of outer bounds on bilinear programs of the form $\mathrm{Tr}\big[M(X\otimes Y)\big]$, maximized with respect to semidefinite constraints on $X$ and $Y$. Applied to the problem of quantum error correction this gives hierarchies of efficiently computable outer bounds on the optimal fidelity for any message dimension and error model. The first level of our hierarchies corresponds to the non-signalling assisted fidelity previously studied by [Leung & Matthews, IEEE Trans.~Inf.~Theory 2015], and positive partial transpose constraints can be added and used to give a sufficient criterion for the exact convergence at a given level of the hierarchy. To quantify the worst case convergence speed of our hierarchies, we derive novel quantum de Finetti theorems that allow imposing linear constraints on the approximating state. In particular, we give finite de Finetti theorems for quantum channels, quantifying closeness to the convex hull of product channels as well as closeness to local operations and classical forward communication assisted channels. As a special case this constitutes a finite version of Fuchs-Schack-Scudo's asymptotic de Finetti theorem for quantum channels. Finally, our proof methods also allow us to answer an open question from [Brandão & Harrow, STOC 2013] by improving the approximation factor of de Finetti theorems with no symmetry from $O(d^{k/2})$ to $\mathrm{poly}(d,k)$, where $d$ denotes local dimension and $k$ the number of copies.

description: To study the diurnal evolution of the convective cloud field, we develop a precipitation cell tracking algorithm which records the merging and fragmentation of convective cells during their life cycles, and apply it on large eddy simulation (LES) data. Conditioning on the area covered by each cell, our algorithm is capable of analyzing an arbitrary number of auxiliary fields, such as the anomalies of temperature and moisture, convective available potential energy (CAPE) and convective inhibition (CIN). For tracks that do not merge or split (termed "solitary"), many of these quantities show generic, often nearly linear relations that hardly depend on the forcing conditions of the simulations, such as surface temperature. This finding allows us to propose a highly idealized model of rain events, where the surface precipitation area is circular and a cell's precipitation intensity falls off linearly with the distance from the respective cell center. The drop-off gradient is nearly independent of track duration and cell size, which allows for a generic description of such solitary tracks, with the only remaining parameter the peak intensity. In contrast to the simple and robust behavior of solitary tracks, tracks that result from merging of two or more cells show a much more complicated behavior. The most intense, long lasting and largest tracks indeed stem from multi-mergers - tracks involved in repeated merging. Another interesting finding is that the precipitation intensity of tracks does not strongly depend on the absolute amount of local initial CAPE, which is only partially consumed by most rain events. Rather, our results speak to boundary layer cooling, induced by rain re-evaporation, as the cause for CAPE reduction, CIN increase and shutdown of precipitation cells.

description: We calculate matter effects on neutrino oscillations relevant for long baseline experiments. In particular, we compare the results obtained with constant density along the neutrino path versus results obtained by incorporating the actual density profiles in the Earth. We study the dependence of the oscillation signal on both $E/Δm^2_{atm}$ and on the angles in the leptonic mixing matrix. We also comment on the influence of $Δm^2_{sol}$ on the oscillations. The results show quantitatively how, as a function of these input parameters, matter effects can cause significant (25 %) changes in the oscillation probabilities. An important conclusion is that matter effects can be useful in amplifying certain neutrino oscillation signals and helping one to obtain measurements of mixing parameters and the magnitude and sign of $Δm^2_{atm}$.

description: This talk will be given by the members of the Research Support Facility (RSF), supporting the Artificial Intelligence for Multiple Long-Term Conditions (AIM) programme of research. The RSF (The Alan Turing Institute, Swansea University, and the University of Edinburgh) is developing data standards, disseminating best practices, and building community around researchers, patients and the public involved in AI for multiple long-term conditions research. These research projects utilise large population health datasets to get sufficient size and coverage to address complex health questions. These population health datasets can be challenging to access and work with. This talk will cover the use-cases for creating synthetic health datasets, in the context of research studies such as this.

This talk will describe our case study with the synthetic versions of the Clinical Practice Research Datalink (CPRD), and how this helps address goals of the AIM programme.

description: Measurements of the distances to SNe Ia have produced strong evidence that the Universe is really accelarating, implying the existence of a nearly uniform component of dark energy with the simplest explanation as a cosmological constant. In this paper a small changing cosmological term is proposed, which is a function of a slow-rolling scalar field, by which the de Sitter primordial black holes' properties, for both charged and uncharged cases, are carefully examined and the relationship between the black hole formation and the energy transfer of the inflaton within this cosmological term is eluciated

description: The thesis contains a collection of poems, which together form an "identity piece," or more specifically, a work of identity-making or construction. The heart of the collection contains poems about the speaker's grandfather, father, an unrequited love and the speaker himself. The speaker is the "I" in the poems.

The collection includes these separate pieces in order to show their significance in the building of the speaker's identity. The thesis attempts to tell the story of the struggle between the identity given by his family (an identity received) and the new identity he seeks to make or construct for himself. The major theme of the collection is the construction of self.

description: We propose a new fractional statistics for arbitrary dimensions, based on an extension of Pauli's exclusion principle, to allow for finite multi-occupancies of a single quantum state. By explicitly constructing the many-body Hilbert space, we obtain a new algebra of operators and a new thermodynamics. The new statistics is different from fractional exclusion statistics; and in a certain limit, it reduces to the case of parafermi statistics.

description: This paper discusses fundamental physical interactions starting from two preliminary assumptions. (a) Although mass of gravity and mass of inertia are equivalent quantities in their measured values, they are qualitatively not identical physical entities. We will take into consideration this difference in our equations. Then it extends this "equivalence-is-not-identity" principle to sources of further fundamental interaction fields, other than gravity. (b) Physical interactions occur between these qualitatively different entities. First it interprets these assumptions. Then, it sketches a picture of fundamental physical fields influenced by the distinction between the two qualitative forms of the individual field-charges and interaction between them. It applies the results of a former publication (Darvas, Concepts of Physics, 2009, 3), which mathematically proved the existence of an invariance between the two isotopic forms of field-charges. It introduces the notion of isotopic-field-charge-spin, proven as a conserved quantity. This conservation predicts the existence of a boson mediating between the two possible isotopic-field-charge-spin states. After these preliminary foundations, it formulates certain consequences in the author s view on the physical structure of matter. Finally the paper discusses how these issues can allow an alternative interpretation of physical experience.
