Improved Seed Methods for Symmetric Positive Definite Linear Equations with Multiple Right-hand Sides

description: We consider symmetric positive definite systems of linear equations with multiple right-hand sides. The seed conjugate gradient method solves one right-hand side with the conjugate gradient method and simultaneously projects over the Krylov subspace thus developed for the other right-hand sides. Then the next system is solved and used to seed the remaining ones. Rounding error in the conjugate gradient method limits how much the seeding can improve convergence. We propose three changes to the seed conjugate gradient method: only the first right-hand side is used for seeding, this system is solved past convergence, and the roundoff error is controlled with some reorthogonalization. We will show that results are actually better with only one seeding, even in the case of related right-hand sides. Controlling rounding error gives the potential for rapid convergence for the second and subsequent right-hand sides.

description: The forward-backward asymmetry of $b$-quark jets on the $Z$-pole measured at LEP/SLD experiments shows us -2.8-$σ$ deviation from the Standard Model (SM) prediction. We examine a possibility of Kaluza-Klein (KK) gluon to explain the $\afbb$ data in a scenario based on the warped extra dimension model by Randall and Sundrum. In this scenario, the KK gluon strongly couples to $b$-quark by an appropriate choice of the bulk quark mass terms. We find that the $\afbb$ data could be explained if the KK gluon mass is few hundred GeV. Constraints on our scenario from the hadron collider experiments are discussed.

As an application, we obtain a description of Gromov-hyperbolic groups among those groups. In particular we prove that any non-elementary Gromov-hyperbolic algebraic group over a non-Archimedean local field of zero characteristic is quasi-isometric to a 3-regular tree. We also extend the study to semidirect products of a general locally compact group by a cyclic group acting by contracting automorphisms.

Comparative phytochemical study of Caprifoliaceae
Creators: name: Glennie, Charles William
Publisher: name: University of British Columbia
Year: 2011

description: A comparative phytochemical study of the Caprifoliaceae was undertaken. No such study has ever been done. Extracts of fresh leaf material from 56 taxa collected throughout North America were examined for their content of phenolic compounds. Acid and base hydrolysis of the extracts yielded a large array of common phenolic acids and several unknowns. The unknowns occurred in small amounts and were not identified. The cyanogenetic glucoside, sambunigrin, was found to occur only in the genus Sambucus. Chlorogenic acid isomers were identified in the unhydrolyzed extracts of all plants examined. A chromatography system for the separation of these isomers is described. The dicaffeoylquinic acid isomers (isochlorogenic acid) occurred in all genera examined except; Sambucus which contained the monocaffeoylquinic acid isomers. Scopoletin, a 6 Me-7-OH-coumarin, was present in hydrolyzed extracts of Weigela. This is the only report of scopoletin in the Caprifoliaceae although other coumarins have been found in Diervilla and Symphoricarpos. A crystalline compound was isolated from extracts of the leaves of Viburnum davidii and was identified as 2 ' , 4, 4'-trihydroxy-dihydrochalcone. This is the first report of this compound being found, in plant material and also it is the first report of a dihydrochaleone with the 2',4’ dihydroxy structure rather than the 2',4',6' trihydroxy structure as found in phloretin. The flavonoids identified in this study yielded either the flavonols kaempferol or quercetin or the flavones apigenin or luteolin on hydrolysis. These four compounds displayed a wide variation of glycosylation and distribution throughout the taxa examined. The flavonols, which are considered to be the more primitive compounds, are found in Viburnum and Sambucus instead of the flavones. This would suggest that these genera are the most primitive of the family. The relatively more advanced flavones are more prominent in Symphoricarpos and Trlosteum thus suggesting that they are the more advanced genera of the family. The comparatively primitive compound amentoflavone (a biflavonyl) was found in Viburnum carlesii and V. X burkwoodii. The occurrence of sambunigrin in Sambucus only and the absence of the dicaffecylquinic esters in Sambucus support the idea that Sambucus is sufficiently different to be put into its own family, Sambucaceae (Hoch, 1892).

description: Inference problems with incomplete observations often aim at estimating population properties of unobserved quantities. One simple way to accomplish this estimation is to impute the unobserved quantities of interest at the individual level and then take an empirical average of the imputed values. We show that this simple imputation estimator can provide partial protection against model misspecification. We illustrate imputation estimators' robustness to model specification on three examples: mixture model-based clustering, estimation of genotype frequencies in population genetics, and estimation of Markovian evolutionary distances. In the final example, using a representative model misspecification, we demonstrate that in non-degenerate cases, the imputation estimator dominates the plug-in estimate asymptotically. We conclude by outlining a Bayesian implementation of the imputation-based estimation.

description: This paper is a sequel to \cite{Berndtsson}. In that paper we studied the vector bundle associated to the direct image of the relative canonical bundle of a smooth Kähler morphism, twisted with a semipositive line bundle. We proved that the curvature of a such vector bundles is always semipositive (in the sense of Nakano). Here we adress the question if the curvature is strictly positive when the Kodaira-Spencer class does not vanish. We prove that this is so provided the twisting line bundle is stricty positive along fibers, but not in general.

Deducing the three gauge interactions from the three Reidemeister moves
Creators: name: Schiller, Christoph
Publisher: name: arXiv
Year: 2009
Subjects: subject: General Physics (physics.gen-ph)
subject: FOS: Physical sciences

description: Possibly the first argument for the origin of the three observed gauge groups and thus for the origin of the three non-gravitational interactions is presented. The argument is based on a proposal for the final theory that models nature at Planck scales as a collection of featureless strands that fluctuate in three dimensions. This approach models vacuum as untangled strands, particles as tangles of strands, and Planck units as crossing switches. Modelling vacuum as untangled strands implies the field equations of general relativity, when applying an argument from 1995 to the thermodynamics of such strands. Modelling fermions as tangles of two or more strands allows to define wave functions as time-averages of oriented strand crossing density. Using an argument from 1980, this allows to deduce the Dirac equation. When fermions are modelled as tangled strands, gauge interactions appear naturally as deformation of tangle cores. The three possible types of observable core deformations are given by the three Reidemeister moves. They naturally lead to a U(1), a broken and parity-violating SU(2), and a SU(3) gauge group. The corresponding Lagrangians also appear naturally. The strand model is unique, is unmodifiable, is consistent with all known data, and makes numerous testable predictions, including the absence of other interactions, of grand unification, of supersymmetry and of higher dimensions. A method for calculating coupling constants seems to appear naturally.

description: We derive the basic canonical brackets amongst the creation and annihilation operators for a two (1 + 1)-dimensional (2D) gauge field theoretic model of an interacting Hodge theory where a U(1) gauge field (A_μ) is coupled with the fermionic Dirac fields (ψand \bar ψ). In this derivation, we exploit the spin-statistics theorem, normal ordering and the strength of the underlying six infinitesimal continuous symmetries (and the concept of their generators) that are present in the theory. We do not use the definition of the canonical conjugate momenta (corresponding to the basic fields of the theory) anywhere in our whole discussion. Thus, we conjecture that our present approach provides an alternative to the canonical method of quantization for a class of gauge field theories that are physical examples of Hodge theory where the continuous symmetries (and corresponding generators) provide the physical realizations of the de Rham cohomological operators of differential geometry at the algebraic level.

description: In quasi-single field inflation models, massive isocurvature modes, that are coupled to the inflaton and have mass of order the Hubble parameter, can have nontrivial impacts on density perturbations, especially non-Gaussianities. We study a simple example of quasi-single field inflation in terms of turning inflaton trajectory. Large bispectra with a one-parameter family of novel shapes arise, lying between the well-known local and equilateral shape. The trispectra can also be very large and its magnitude tNL can be much larger than fNL squared.

description: We prove that for a combined system of classical and quantum particles, it is possible to write a dynamics for the classical particles that incorporates in a natural way the Boltzmann equilibrium population for the quantum subsystem. In addition, these molecular dynamics do not need to assume that the electrons immediately follow the nuclear motion (in contrast to any adiabatic approach), and do not present problems in the presence of crossing points between different potential energy surfaces (conical intersections or spin-crossings). A practical application of this molecular dynamics to study the effect of temperature in molecular systems presenting (nearly) degenerate states - such as the avoided crossing in the ring-closure process of ozone - is presented.

Despite such rise, not much work can be found in aspects of preprocessing and cleaning dirty texts from online sources. This paper presents an enhancement of an Integrated Scoring for Spelling error correction, Abbreviation expansion and Case restoration (ISSAC). ISSAC is implemented as part of a text preprocessing phase in an ontology engineering system. New evaluations performed on the enhanced ISSAC using 700 chat records reveal an improved accuracy of 98% as compared to 96.5% and 71% based on the use of only basic ISSAC and of Aspell, respectively.

description: Recent combined analyses of the CMB and galaxy cluster data reveal unexpectedly large and anisotropic peculiar velocity fields at large scales. We study cosmic models with included vorticity, acceleration and total angular momentum of the Universe in order to understand the phenomenon. The Zeldovich model is used to mimic the low redshift evolution of the angular momentum. Solving coupled evolution equations of the second kind for density-contrast in corrected Ellis-Bruni covariant and gauge-invariant formalism one can properly normalize and evaluate integrated Sachs-Wolfe effect and peculiar velocity field. The theoretical results compared to the observations favor a much larger matter content of the Universe than that of the concordance model. Large-scale flows appear anisotropic with dominant components placed in the plane perpendicular to the axis of vorticity(rotation). The integrated Sachs-Wolfe term has negative contribution to the CMB fluctuations for the negative cosmological constant and it can explain the observed small power of the CMB TT spectrum at large scales. The rate of the expansion of the Universe can be substantially affected by the angular momentum if its magnitude is large enough.

description: In this thesis, resynchronization of a synchronous machine from a slipping state is considered. A set of equations for the slipping machine are developed. Slip tests on a dynamic test model are done to compare with computed results. A critical damping necessary for resynchronization is investigated, and an expression is derived. Tests are again carried out on a power system set up on the dynamic test model to verify the result. Finally, a nonlinear optimal control is developed and implemented on the test model.

description: In this paper, we study the quantization errors of modulo sigma-delta modulated finite, asymptotically-infinite, infinite causal stable ARMA processes. We prove that the normalized quantization error can be taken as a uniformly distributed white noise for all the cases. Moreover, we find that this nice property is guaranteed by two different mechanisms: the high-enough quantization resolution \cite{Bennett1948}-\cite{WidrowKollar2008} and the asymptotic convergence of quantization errors for some quasi-stationary processes \cite{ChouGray1991}-\cite{LiChenLiZhang2009}, for different cases. But the assumption of the smooth density of the sampled random processes is needed in all the cases.

Remarkably the pump-probe response for the opto mechanical system shares all the features of the Lambda system as discovered by Harris and collaborators.

description: In Grand Unified Theories (GUTs), the Standard Model (SM) gauge couplings need not be unified at the GUT scale due to the high-dimensional operators. Considering gravity mediated supersymmetry breaking, we study for the first time the generic gauge coupling relations at the GUT scale, and the general gaugino mass relations which are valid from the GUT scale to the electroweak scale at one loop. We define the index k for these relations, which can be calculated in GUTs and can be determined at the Large Hadron Collider and the future International Linear Collider. Thus, we give a concrete definition of the GUT scale in these theories, and suggest a new way to test general GUTs at future experiments. We also discuss five special scenarios with interesting possibilities. With our generic formulae, we present all the GUT-scale gauge coupling relations and all the gaugino mass relations in the SU(5) and SO(10) models, and calculate the corresponding indices k. Especially, the index k is 5/3 in the traditional SU(5) and SO(10) models that have been studied extensively so far. Furthermore, we discuss the field theory realization of the U(1) flux effects on the SM gauge kinetic functions in F-theory GUTs, and calculate their indices k as well.

description: We study Miyaoka-type semistability criteria for principal Higgs G-bundles E on complex projective manifolds of any dimension. We prove that E has the property of being semistable after pullback to any projective curve if and only if certain line bundles, obtained from some characters of the parabolic subgroups of G, are numerically effective. One also proves that these conditions are met for semistable principal Higgs bundles whose adjoint bundle has vanishing second Chern class. In a second part of the paper, we introduce notions of numerical effectiveness and numerical flatness for principal (Higgs) bundles, discussing their main properties. For (non-Higgs) principal bundles, we show that a numerically flat principal bundle admits a reduction to a Levi factor which has a flat Hermitian-Yang-Mills connection, and, as a consequence, that the cohomology ring of a numerically flat principal bundle with real coefficients is trivial. To our knowledge this notion of numerical effectiveness is new even in the case of (non-Higgs) principal bundles.

description: Urban trees make significant economic, environmental, social, cultural and spiritual contributions to people and other sentient beings. They are also easily influenced by human activities. There is an ample literature demonstrating that private property is increasingly important for nature conservation and local species changes. Although there is much of research on the reasons for tree death, there are few direct data on the influences of ownership changes on changes in garden trees. The current study evaluates the impacts of property sales, surface changes and area on tree changes over a 9 year period between 2004 and 2013 in Sandy Bay, Tasmania, Australia. Aerial image analysis and ground survey were used to collect data from two sets of properties, one selected on the basis of observable change and another selected randomly. We found that property hard surface, property size and initial tree numbers better predicted tree loss than the frequency of sales of properties.

description: In the presence of spin-orbit coupling and inversion symmetry of the lateral confinement potential a single electron does not exhibit matrix Berry phases in quasi-two-dimensional semiconductor quantum dots. In such a system we investigate whether many-body correlation effects can lead to finite matrix Berry phases. We find that the transformation properties of many-electron wavefunctions under two-dimensional inversion operation do not allow finite matrix Berry phases. This effect is exact and is independent of the form of electron-electron interactions. On the other hand, quasi-two-dimensional semiconductor quantum dots with lateral confinement potential without inversion symmetry can have finite matrix Berry phases. We find that many-body quantum fluctuations can change matrix Berry phases significantly in such systems.

description: We develop relativistic wave equations in the framework of the new non-hermitian ${\cal PT}$ quantum mechanics. The familiar Hermitian Dirac equation emerges as an exact result of imposing the Dirac algebra, the criteria of ${\cal PT}$-symmetric quantum mechanics, and relativistic invariance. However, relaxing the constraint that in particular the mass matrix be Hermitian also allows for models that have no counterpart in conventional quantum mechanics. For example it is well-known that a quartet of Weyl spinors coupled by a Hermitian mass matrix reduces to two independent Dirac fermions; here we show that the same quartet of Weyl spinors, when coupled by a non-Hermitian but $\cal{PT}$ symmetric mass matrix, describes a single relativistic particle that can have massless dispersion relation even though the mass matrix is non-zero.The ${\cal PT}$-generalized Dirac equation is also Lorentz invariant, unitary in time, and CPT respecting, even though as a non-interacting theory it violates ${\cal P}$ and ${\cal T}$ individually. The relativistic wave equations are reformulated as canonical fermionic field theories to facilitate the study of interactions, and are shown to maintain many of the canonical structures from Hermitian field theory, but with new and interesting new possibilities permitted by the non-hermiticity parameter $m_2$.

description: We discuss the constraints on the parameters of a Yukawa interaction obtained from the indirect measurements of the Casimir pressure between parallel plates using the sphere-plate configuration. Recently, it was claimed in the literature that the application of the proximity force approximation (PFA) to the calculation of a Yukawa interaction in the sphere-plate configuration could lead to a large error of order 100\% in the constraints obtained. Here we re-calculate the constraints both exactly and using the PFA, and arrive at identical results. We elucidate the reasons why an incorrect conclusion was obtained suggesting that the PFA is inapplicable to calculate the Yukawa force.

An analysis of youth mental health outcomes during the COVID-19 Pandemic beyond the first wave: how family factors impacted negative outcomes
Creators: name: Tran, Alvin A.
Publisher: name: No Publisher Supplied
Year: 2025

description: The COVID-19 pandemic was a destabilizing global event which has been associated with significant increases in mental health concerns. Children and adolescents were especially vulnerable to negative mental health outcomes throughout this time, with notably worse outcomes being reported for clinical youth compared to their non-clinical counterparts. While research about the negative mental health impact of the pandemic during the first wave has become more readily available, little is known about the degree of impact which the pandemic has had on youth in subsequent waves. Further, family-related factors, such as family cohesion, conflict, and parental experiential avoidance (PEA), impacted by family environment disruptions, may have had an impact on which youth experienced better or worse mental health outcomes. This study aimed to analyze the pandemic’s influence on youth mental health outcomes, specifically anxiety and depressive symptoms, during the two pandemic waves which followed the initial surge for depressed and anxious youth and their non-clinical counterparts, as well as the role of family factors. It was hypothesized that clinical youth (N = 69, ages 9-17) would have worse mental health outcomes compared to their non-clinical counterparts (N = 60, ages 9-17) during both Wave 2 and Wave 3 of the pandemic and that family conflict and PEA would be associated with worse youth mental health outcomes, particularly for clinical youth. It was also hypothesized that family cohesion would be associated with better youth mental health outcomes, especially for clinical youth. Results indicated that there were no significant differences for clinical and nonclinical youth between pandemic waves cohorts in mental health outcomes. Family factors did play a role. Greater family cohesion was associated with lower depressive symptoms for both clinical and non-clinical youth, with more pronounced effects on clinical youth. Second, greater PEA was associated with higher depression symptoms in both clinical and non-clinical youth, but this increase was steeper for clinical youth. Taken together, these findings show that both vulnerable and normative youth experienced a significant impact from secondary waves of the pandemic and that specific family processes interact with clinical status in predicting health outcomes.

description: Measuring subdiffraction separations between single fluorescent particles is important for biological, nano-, and medical-technology studies. Major challenges include (i) measuring changing molecular separations with high temporal resolution while (ii) using identical fluorescent labels. Here we report a method that measures subdiffraction separations between two identical fluorophores by using a single image of milliseconds exposure time and a standard single-molecule fluorescent imaging setup. The fluorophores do not need to be bleached and the separations can be measured down to 40 nm with nanometer precision. The method is called single-molecule image deconvolution -- SMID, and in this article it measures the standard deviation (SD) of Gaussian-approximated combined fluorescent intensity profiles of the two subdiffraction-separated fluorophores. This study enables measurements of (i) subdiffraction dimolecular separations using a single image, lifting the temporal resolution of seconds to milliseconds, while (ii) using identical fluorophores. The single-image nature of this dimer separation study makes it a single-image molecular analysis (SIMA) study.

An SO(10) Grand Unified Theory of Flavor

description: We present a supersymmetric SO(10) grand unified theory (GUT) of flavor based on an $S_4$ family symmetry. It makes use of our recent proposal to use SO(10) with type II seesaw mechanism for neutrino masses combined with a simple ansatz that the dominant Yukawa matrix (the {\bf 10}-Higgs coupling to matter) has rank one. In this paper, we show how the rank one model can arise within some plausible assumptions as an effective field theory from vectorlike {\bf 16} dimensional matter fields with masses above the GUT scale. In order to obtain the desired fermion flavor texture we use $S_4$ flavon multiplets which acquire vevs in the ground state of the theory. By supplementing the $S_4$ theory with an additional discrete symmetry, we find that the flavon vacuum field alignments take a discrete set of values provided some of the higher dimensional couplings are small. Choosing a particular set of these vacuum alignments appears to lead to an unified understanding of observed quark-lepton flavor: (i) the lepton mixing matrix that is dominantly tri-bi-maximal with small corrections related to quark mixings; (ii) quark lepton mass relations at GUT scale: $m_b\simeq m_τ$ and $m_μ\simeq 3 m_s$ and (iii) the solar to atmospheric neutrino mass ratio $m_\odot/m_{\rm atm}\simeq θ_{\rm Cabibbo}$ in agreement with observations. The model predicts the neutrino mixing parameter, $U_{e3} \simeq θ_{\rm Cabibbo}/(3\sqrt2) \sim 0.05$, which should be observable in planned long baseline experiments.

Component weights of Douglas fir, western hemlock and western red cedar biomass for simulation of amount and distribution of forest fuels
Creators: name: Kurucz, J.
Publisher: name: University of British Columbia
Year: 2011

description: Potential uses of dry weight information for simulation, and sources of data, for simulation of forest fuels were discussed. Tree and crown component dry weights of 23 Douglas fir, 18 western hemlock, and 23 western red cedar trees expanded to 314 "model" trees were investigated. Data were collected on the University Research Forest near Haney, British Columbia. Multiple regression techniques were used for the analysis. The best four independent variables are listed and the possibility of retaining a single independent variable, with its implications, are discussed. All predicting equations were conditioned to zero intercept and statistically tested for significance by the F-test. Of the independent variables tested, the combined variable of breast height diameter squared times total tree height was most closely related to tree component dry weights. The product of diameter and crown width squared was found to be the best single variable to describe crown component dry weights for Douglas fir. The dry weights of western hemlock and western red cedar crown components were most closely associated with breast height diameter times crown length. Reliable estimates of tree component dry weights were obtained. Crown components were highly variable and widely dispersed about the mean which resulted in less accurate estimates.
