description: We consider the benefits of measuring cosmic statistical anisotropy from redshift-space correlators of the galaxy number density fluctuation and the peculiar velocity field without adopting the plane-parallel (PP) approximation. Since the correlators are decomposed using the general tripolar spherical harmonic (TripoSH) basis, we can deal with wide-angle contributions untreatable by the PP approximation, and at the same time, target anisotropic signatures can be cleanly extracted. We, for the first time, compute the covariance of the TripoSH decomposition coefficient and the Fisher matrix to forecast the detectability of statistical anisotropy. The resultant expression of the covariance is free from nontrivial mixings between each multipole moment caused by the PP approximation and hence the detectability is fully optimized. Compared with the analysis under the PP approximation, the superiority in detectability is always confirmed, and it is highlighted, especially in the cases that the shot noise level is large and that target statistical anisotropy has a blue-tilted shape in Fourier space. The application of the TripoSH-based analysis to forthcoming all-sky survey data could result in constraints on anisotropy comparable to or tighter than the current cosmic microwave background ones.

description: In response to the introduction and rapid spread of soybean aphid as a major new invasive pest of soybean in North America, farmers who attended winter crop meetings in four states in North Central US were surveyed about their treatment of and knowledge about soybean aphids for crop years 2004, 2005, and 2006. Thirteen percent, 84%, and 35% of the farmers indicated they had treated for soybean aphid in 2004, 2005, and 2006, respectively. The average of the soybean acreage treated in each year was 50%, 87%, and 81%, respectively. Overall, the farmers showed a good understanding of soybean aphids and their impact on soybeans. Over 80% knew soybean aphids could repopulate and cause yield damage after an insecticide treatment. Seventy-five percent knew aphids damaged soybeans by sucking sap. Almost 80% said the frequency with which aphids should be treated for profitable control depends on aphid counts, weather conditions, and plant stage. On average, just under 70% considered an average of 250 aphids per plant to be the lowest density for profitable insecticide spraying. Scouting reports were selected by 84 to 94% of the farmers as very important information for the treatment decision; plant growth stage was the second most frequent selection.

description: Axions and axion-like particles (ALPs) are well-motivated low-energy relics of high-energy extensions of the Standard Model, which interact with the known particles through higher-dimensional operators suppressed by the mass scale $Λ$ of the new-physics sector. Starting from the most general dimension-5 interactions, we discuss in detail the evolution of the ALP couplings from the new-physics scale to energies at and below the scale of electroweak symmetry breaking. We derive the relevant anomalous dimensions at two-loop order in gauge couplings and one-loop order in Yukawa interactions, carefully considering the treatment of a redundant operator involving an ALP coupling to the Higgs current. We account for one-loop (and partially two-loop) matching contributions at the weak scale, including in particular flavor-changing effects. The relations between different equivalent forms of the effective Lagrangian are discussed in detail. We also construct the effective chiral Lagrangian for an ALP interacting with photons and light pseudoscalar mesons, pointing out important differences with the corresponding Lagrangian for the QCD axion.

description: A recently developed high-order implicit shock tracking (HOIST) framework for resolving discontinuous solutions of inviscid, steady conservation laws [41, 43] is extended to the unsteady case. Central to the framework is an optimization problem which simultaneously computes a discontinuity-aligned mesh and the corresponding high-order approximation to the flow, which provides nonlinear stabilization and a high-order approximation to the solution. This work extends the implicit shock tracking framework to the case of unsteady conservation laws using a method of lines discretization via a diagonally implicit Runge-Kutta method by "solving a steady problem at each timestep". We formulate and solve an optimization problem that produces a feature-aligned mesh and solution at each Runge-Kutta stage of each timestep, and advance this solution in time by standard Runge-Kutta update formulas. A Rankine-Hugoniot based prediction of the shock location together with a high-order, untangling mesh smoothing procedure provides a high-quality initial guess for the optimization problem at each time, which results in rapid convergence of the sequential quadratic programing (SQP) optimization solver. This method is shown to deliver highly accurate solutions on coarse, high-order discretizations without nonlinear stabilization and recover the design accuracy of the Runge-Kutta scheme. We demonstrate this framework on a series of inviscid, unsteady conservation laws in both one- and two- dimensions. We also verify that our method is able to recover the design order of accuracy of our time integrator in the presence of a strong discontinuity.

description: Prior to the middle of the twentieth century the margins that have demarcated the subject matter of the several social sciences had been relatively stable since the latter decades of the nineteenth century. Since mid-century, however, a number of intellectual and institutional developments have conspired to call into question traditional disciplinary boundaries. In this paper I address the role of disciplinary imperialism, colonialism and collaboration in advancing social science knowledge about development processes and in the design of development policy and institutions. I conclude the paper with several case studies of collaboration across disciplines that have advanced knowledge and practice in the field of development.
Assessing and promoting windfirmness in conifers in British Columbia
Creators: name: Mitchell, Stephen Jarvis
Publisher: name: University of British Columbia
Year: 2009

description: Windthrow is a natural disturbance agent which disrupts forest and stand level plans in British Columbia (BC). The objectives of this thesis were to: i) review the factors contributing to windthrow risk in BC, ii) investigate patterns of stem growth in conifers following thinning and consider their use for diagnosing windfirmness; and iii) present a diagnostic method of assessing windthrow risk suited to the heterogeneity of BC's forests. Stem analysis was used to reconstruct the post-thinning stem growth patterns for 25 Sitka spruce (Picea sitchensis (Bong.) Carr.) from a coastal stand which was thinned in 1980, and 45 Douglas-fir {Pseudotsuga menziesii var. glauca (Beissn.) Franco) from a stand on the interior plateau with 1978 and 1984 thinned portions. Both stands had very high initial densities and sample trees represented a range of stem slenderness in the thinned and control portions. Following thinning, height increment was temporarily reduced, radial increment increased and the allocation of radial increment became more basal in each of the three thinning treatments. The post-thinning stem slenderness curves were reverse-S in shape with initially more slender trees showing the greatest decline. Critical turning moments of 36 Douglas-fir trees winched to failure were related to tree size. With a uniform wind profile over the crown length, critical wind speed declined with slenderness. The relationship between safety factor and slenderness varied between treatments depending on the attenuation of the within-canopy wind profile. The short term growth responses, their relationship with initial stem slenderness and the shape of the slendemess adjustment curves suggested a pattern of form re-equilibration following thinning. It appears that observation of the magnitude and duration of post-thinning stem form adjustment is a useful diagnostic tool for scheduling subsequent thinning entries in stands with high initial slendemess, and for identifying more vulnerable trees. Forest managers in BC use a system of site and stand diagnosis during the preparation of stand level prescriptions. A diagnostic framework for windthrow risk is presented which can be incorporated into the prescription process. In this framework, the principle of acclimative growth is used in assessing the stand hazard and treatment risk components of windthrow risk. Recommendations are made for a comprehensive program of windthrow management.

description: The NANOGrav collaboration has recently reported evidence for the existence of a stochastic gravitational wave background in the 1-100 nHz frequency range. We argue that such background could have been produced by magneto-hydrodynamic (MHD) turbulence at the QCD scale. From the NANOGrav measurement one can infer the magnetic field parameters: comoving field strength close to microGauss and a correlation length close to 10\% of the Hubble radius at the QCD phase transition epoch. We point out that the turbulent decay of a non-helical magnetic field with such parameters leads to a magnetic field at the recombination epoch, which would be sufficiently strong to provide a solution to the Hubble tension problem, as recently proposed. We also show that the MHD turbulence interpretation of the NANOGrav signal can be tested via measurements of the relic magnetic field in the voids of the large scale structure, with gamma-ray telescopes like CTA.

Quantum Liquid Crystal Phases in Fermionic Superfluids with Pairing between Fermion Species of Unequal Densities

description: Superfluidity in fermionic systems originates from pairing of fermions, and Bose condensation of these so-called Cooper pairs. The Cooper pairs are usually made of fermions of different species; for example in superconductors they are pairs of electrons with opposite spins. Thus the most favorable situation for pairing and superfluidity is when the two species of fermions that form pairs have the same density. This paper studies the possible superfluid states when the two pairing species have different densities, and show that the resultant states have remarkable similarities to the phases of liquid crystals. This enables us to provide a unified description of the possible pairing phases, and understand the phase transitions among them.

description: We propose that reactor experiments could be used to constrain the environment dependence of neutrino mass and mixing parameters, which could be induced due to an acceleron coupling to matter fields. There are several short-baseline reactor experiment projects with different fractions of air and earth matter along the neutrino path. Moreover, the short baselines, in principle, allow the physical change of the material between source and detector. Hence, such experiments offer the possibility for a direct comparison of oscillations in air and matter. We demonstrate that for $\sin^2 2 θ_{13} \gtrsim 0.04$, two reactor experiments (one air, one matter) with baselines of at least 1.5 km can constrain any oscillation effect which is different in air and matter at the level of a few per cent. Furthermore, we find that using the same experiment while physically moving the material between source and detector improves systematics.

On sample complexity for computational pattern recognition

description: In statistical setting of the pattern recognition problem the number of examples required to approximate an unknown labelling function is linear in the VC dimension of the target learning class. In this work we consider the question whether such bounds exist if we restrict our attention to computable pattern recognition methods, assuming that the unknown labelling function is also computable. We find that in this case the number of examples required for a computable method to approximate the labelling function not only is not linear, but grows faster (in the VC dimension of the class) than any computable function. No time or space constraints are put on the predictors or target functions; the only resource we consider is the training examples. The task of pattern recognition is considered in conjunction with another learning problem -- data compression. An impossibility result for the task of data compression allows us to estimate the sample complexity for pattern recognition.

description: We present aspects of a model which attempts to unify the creation of cold dark matter, a CP-violating baryon asymmetry, and also a small, residual vacuum energy density, in the early universe. The model contains a primary scalar (inflaton) field and a primary pseudoscalar field, which are initially related by a cosmological, chiral symmetry. The nonzero vacuum expectation value of the pseudoscalar field spontaneously breaks CP invariance.

We work with two simple parameterizations of the dynamical dark energy equation of state and the constant dark energy equation of state. Using observational data coming from the new 182 Gold type Ia supernova samples, the shift parameter of the Cosmic Microwave Background given by the three-year Wilkinson Microwave Anisotropy Probe observations, and the baryon acoustic oscillation measurement from the Sloan Digital Sky Survey, we perform a statistical joint analysis of different forms of phenomenological interactions between dark energy and dark matter.

Confinement- Deconfinement Phase Transition and Fractional Instanton Quarks in Dense Matter

description: We present arguments suggesting that large size overlapping instantons are the driving mechanism of the confinement-deconfinement phase transition at nonzero chemical potential mu. The arguments are based on the picture that instantons at very large chemical potential in the weak coupling regime are localized configurations with finite size ρ\simμ^{-1}. At the same time, the same instantons at smaller chemical potential in the strong coupling regime are well represented by the so-called instanton-quarks with fractional topological charge 1/N_c. We estimate the critical chemical potential mu_c(T) where transition between these two regimes takes place. We identify this transition with confinement- deconfinement phase transition. We also argue that the instanton quarks carry magnetic charges. As a consequence of it, there is a relation between our picture and the standard t'Hooft and Mandelstam picture of the confinement. We also comment on possible relations of instanton-quarks with "periodic instantons", " center vortices", and "fractional instantons" in the brane construction. We also argue that the variation of the external parameter mu, which plays the role of the vacuum expectation value of a "Higgs" field at mu >> Λ_{QCD}, allows to study the transition from a "Higgs -like" gauge theory (weak coupling regime, mu>> Λ_{QCD}) to ordinary QCD (strong coupling regime, mu<< Λ_{QCD}). We also comment on some recent lattice results on topological charge density distribution which support our picture.

The new species are both likely morphologically related to L. potanini (Kirejtshuk, 1979) from Sichuan and to L. conjungens (Grouvelle, 1910) from Yunnan. These new species clearly differ from their related taxa by details of the body shape and color, and the distinct shape of the male and female genitalia. Both new species are likely associated as larvae with a member of the genus Phlomoides Moench (Lamiaceae).

description: A new genus, Breviclypeus gen. nov., endemic to South Africa, is erected. The type species is here designated to be Agenius rufipennis Gory & Percheron 1833 (comb. nov.). A second species, Campulipus plagosus (Pèringuey, 1885) is recognized to belong into this new genus (comb. nov.). Consequently, the genus Campulipus Kirby, 1827 is now represented by three species only, Campulipus limbatus (Olivier, 1789), Campulipus clavus (Schaum, 1844) and Campulipus suturalis (Waterhouse, 1885). A fourth taxon, Agenius nobilis J. Thomson, 1878 is here transferred to Campulipus (comb. nov.) and synonymized with C. limbatus (syn. nov.) The two genera not only exhibit key morphological differences, but also occupy different habitats and diverge substantially in their ecology. An updated key of the genera of South African Trichiina is also provided. A separate key is provided for the genus Breviclypeus.

description: We apply a probabilistic approach to study the computational complexity of analog computers which solve linear programming problems. We analyze numerically various ensembles of linear programming problems and obtain, for each of these ensembles, the probability distribution functions of certain quantities which measure the computational complexity, known as the convergence rate, the barrier and the computation time. We find that in the limit of very large problems these probability distributions are universal scaling functions. In other words, the probability distribution function for each of these three quantities becomes, in the limit of large problem size, a function of a single scaling variable, which is a certain composition of the quantity in question and the size of the system. Moreover, various ensembles studied seem to lead essentially to the same scaling functions, which depend only on the variance of the ensemble. These results extend analytical and numerical results obtained recently for the Gaussian ensemble, and support the conjecture that these scaling functions are universal.

description: In Viet Nam, the diversification of CGPRT crops is the main thrust of poverty alleviation in remote and mountainous areas with new opportunities in the market. However, the sustainable development of these commodity chains is in question due to the lack of integrated policy for value chain development and assuring the participation of the poor in the value chains. Two case studies of cassava and maize commodity chains respectively in Yen Bai and Son La provinces suggest ways to encompass these challenges of diversification.

description: We provide an easy method to obtain the kinetic energy fraction in gravitational waves, generated during a cosmological first-order phase transition, as a function of only the wall velocity and quantities that can be determined from the particle physics model at the nucleation temperature. This generalizes recent work that achieved this goal for detonations. Here we present the corresponding results for deflagrations and hybrids. Unlike for detonations, the sound speed in the symmetric phase also enters the analysis. We perform a detailed comparison between our model-independent approach and other approaches in the literature. We provide a Python code snippet to determine the kinetic energy fraction $K$ as a function of the wall velocity, the two speeds of sound and the strength parameter of the phase transition. We also assess how realistic sizable deviations in speed of sound are close to the phase transition temperature in a specific model.

description: We implement extraction of Coq programs to functional languages based on MetaCoq's certified erasure. As part of this, we implement an optimisation pass removing unused arguments. We prove the pass correct wrt. a conventional call-by-value operational semantics of functional languages. We apply this to two functional smart contract languages, Liquidity and Midlang, and to the functional language Elm. Our development is done in the context of the ConCert framework that enables smart contract verification. We contribute a verified boardroom voting smart contract featuring maximum voter privacy such that each vote is kept private except under collusion of all other parties. We also integrate property-based testing into ConCert using QuickChick and our development is the first to support testing properties of interacting smart contracts. We test several complex contracts such as a DAO-like contract, an escrow contract, an implementation of a Decentralized Finance (DeFi) contract which includes a custom token standard (Tezos FA2), and more. In total, this gives us a way to write dependent programs in Coq, test them semi-automatically, verify, and then extract to functional smart contract languages, while retaining a small trusted computing base of only MetaCoq and the pretty-printers into these languages.

description: This paper builds on the available knowledge on what drives firms’ production choices towards circular economy practices to shed new light on a so far quite neglected dimension: the role of organizational settings. Being the transition to a more circular economy systemic in nature, it draws not only on technological but also on organizational changes and new set-ups. Coherently, the paper investigates how certain organizational settings (such as practices of communication to employees on critical aspects of the life of the company, the implementation of new performance evaluation mechanisms and incentive-based payment methods and the implementation of changes in recruitment and training of (new) employees affect the adoption of circular economy innovation. The work is empirical, and it draws on a newly collected dataset representative for Italian manufacturing firms in 2017-2018. Results show new light on the role of such organizational set-ups, which are found to be making the transition towards a circular economy more effective.

description: We examine the post-Newtonian limit of the minimal exponential measure (MEMe) model presented in [J. C. Feng, S. Carloni, Phys. Rev. D 101, 064002 (2020)] using an extension of the parameterized post-Newtonian (PPN) formalism which is also suitable for other type-I minimally modified Gravity theories. The new PPN expansion is then used to calculate the monopole term of the post-Newtonian gravitational potential and to perform an analysis of circular orbits within spherically symmetric matter distributions. The latter shows that the behavior does not differ significantly from that of general relativity for realistic values of the MEMe model parameter $q$. Instead the former shows that one can use precision measurements of Newton's constant $G$ to improve the constraint on $q$ by up to $10$ orders of magnitude.

description: Bose-Fermi mixtures in one dimension are studied in detail on the basis of an exact solution. Corresponding to three possible choices of the referecce state in the quantum inverse scattering method, three sets of Bethe-ansatz equations are derived explicitly. The features of the ground state and low-lying excitations are investigated. The ground state phase diagram caused by the external field and chemical potential is obtained.
$κ$TNG: Effect of Baryonic Processes on Weak Lensing with IllustrisTNG Simulations

description: We study the effect of baryonic processes on weak lensing (WL) observables with a suite of mock WL maps, the $κ$TNG, based on the cosmological hydrodynamic simulations IllustrisTNG. We quantify the baryonic effects on the WL angular power spectrum, one-point probability distribution function (PDF), and number counts of peaks and minima. We also show the redshift evolution of the effects, which is a key to distinguish the effect of baryons from fundamental physics such as dark energy, dark matter, and massive neutrinos. We find that baryonic processes reduce the small-scale power, suppress the tails of the PDF, peak and minimum counts, and change the total number of peaks and minima. We compare our results to existing semi-analytic models and hydrodynamic simulations, and discuss the source of discrepancies. The $κ$TNG suite includes 10,000 realisations of $5 \times 5 \, \mathrm{deg}^2$ maps for 40 source redshifts up to $z_s = 2.6$, well covering the range of interest for existing and upcoming weak lensing surveys. We also produce the $κ$TNG-Dark suite of maps, generated based on the corresponding dark matter only IllustrisTNG simulations. Our mock maps are suitable for developing analytic models that incorporate the effect of baryons, but also particularly useful for studies that rely on mass maps, such as non-Gaussian statistics and machine learning with convolutional neural networks. The suite of mock maps is publicly available at Columbia Lensing (http://columbialensing.org).

description: Consequences of larval competition at the population level provide explanation for the differences in relative abundance of Aedes aegypti and Aedes albopictus in different geographical regions. The outcome of competition is assessed through the estimates of the life history traits as a response to varying density and resource available for larval development. In the present study, variations in the life history traits due to density-dependent intra- and inter- specific competition involving A. aegypti and A. albopictus were assessed following the minimalist model. The instar-I larvae (0-day old F2 generation) of both Aedes species were reared to the adult stages using the initial rearing density of 1, 2, 4 and 6 (individuals/10ml) in multiple replicates. The age at pupation, pupal weight, adult weight and adult wing length of the individuals were considered as the response variables and surrogates of estimating the competitive interactions. Density dependent variations in the competitive interactions were evident for both the mosquitoes with reference to the selected life history traits. In A. aegypti, the life history traits varied with the levels of competition, which was not observed for A. albopictus. Although the density levels considered in the present instance were lower than in earlier studies, the observations were similar, with A. albopictus being competitively superior. It appears that irrespective of the density levels, interspecific competition affects A. aegypti and thus may bear population level consequences and overall abundance in the areas where both species are present.

description: The phenomenological model for cell shape deformation and cell migration (Chen et.al. 2018; Vermolen and Gefen 2012) is extended with the incorporation of cell traction forces and the evolution of cell equilibrium shapes as a result of cell differentiation. Plastic deformations of the extracellular matrix are modelled using morphoelasticity theory. The resulting partial differential differential equations are solved by the use of the finite element method. The paper treats various biological scenarios that entail cell migration and cell shape evolution. The experimental observations in Mak et.al. (2013), where transmigration of cancer cells through narrow apertures is studied, are reproduced using a Monte Carlo framework.
Fine-scale population structure of masked shrews (Sorex cinereus) in an experimentally fragmented forest
Creators: name: Maydan, Jason Stephen
Publisher: name: University of British Columbia
Year: 2009

description: Habitat fragmentation is perhaps the most important issue facing conservation efforts today. Forests in BC are becoming increasingly fragmented and knowledge about how species respond to different types of forest fragmentation is important for effective management of biological resources. This thesis attempts to use genetic techniques to address this issue. The population genetic structure of masked shrews, Sorex cinereus, was measured for a population in an experimentally fragmented forest near Sicamous Creek, BC. Two highly polymorphic microsatellite markers revealed a significant deficit of heterozygotes in the population (Fis=0.31), which has not previously been reported for shrew populations but may be partly due to the presence of null alleles at these loci. Estimates of pairwise relatedness reveal family structure in the population, wherein related individuals tend to be sampled near one another. This may explain the significant difference that is observed in allelic and genotypic distributions between forest treatment blocks, despite the low FST over the study site (0.006). No significant difference in population structure between types of harvest treatments and the uncut controls was observed. Since only 3 generations of shrews have passed since logging of the study site, these results describe the short-term impact of forest harvest on the population structure of masked shrews and should be supplemented with future studies in order to gauge the long-term effects of habitat fragmentation on the population.

description: We present analytical expressions and numerical illustrations for the ground-state density distribution of an ideal gas of spin-polarized fermions moving in two dimensions and driven to rotate in a harmonic well of circular or elliptical shape. We show that with suitable choices of the strength of the Lorentz force for charged fermions, or of the rotational frequency for neutral fermions, the density of states can be tuned as a function of the angular momentum so as to display a prominent shell structure in the spatial density profile of the gas. We also show how this feature of the density profile is revealed in the static structure factor determining the elastic light scattering spectrum of the gas.
