description: We investigate the atomic diffractions of a Bose-Einstein condensate in quantized light fields. Situations in which the light fields are in number states or coherent states are studied theoretically. Analytical derivation and numerical calculation are carried out to simulate the dynamics of the atomic motion. In condition that atoms are scattered by light in the number states with imbalanced photon number distribution, the atomic transitions between different momentum modes would sensitively depend on the transition order and the photon number distribution. The number-state-nature of the light fields modifies the period of atomic momentum oscillations and makes forward and backward atomic transitions unequal. For light fields in coherent states, no matter the intensities of the light fields are balanced or not, the atomic diffractions are symmetric and independent on the transition order.
title: Organisational Learning, Politics and Change: The Mundane and the Extraordinary in Peacebuilding. A case study of OneVoice (US), Darkenu (Israel), Zimam (Palestine) and Solutions Not Sides (SNS) (UK)

description: How do international hybrid NGO/SMOs learn to create political space for change and transformation in the context of the Israeli-Palestinian conflict? Addressing this overarching research question, this thesis concentrates on how organisational learning takes place and what its relationship with politics might be. Four peacebuilding organisations in Israel, Palestine, the US and UK are the focus of the research. These units of analysis, conceptualised as hybrid non-governmental (NGO)/social movement organisations (SMOs), are used to identify and analyse some of the as yet unexplored political dimensions of organisational learning which is understood as processes, mechanisms, sites and outcomes of learning. The thesis argues that organisational learning can provide a lens for understanding these organisations’ multiple levels of engagement with politics and change and transformation. The research uses mixed qualitative methods (interviews, focus groups, participant observation, documentary analysis of organisational materials) with multiple stakeholder respondents (activists, staff, trustees, external stakeholders) associated with each of the organisations. Politics is characterised as involving the exercise of power. Change and transformation are analysed and evidenced both through individual capacity building which leads to political participation as well as through organisations’ abilities to adapt in order to collectively influence norms and values and to lobby for national political change. The mundane of the thesis title can be found in the incremental organisational learning, which is part of working to bring about structural change for peacebuilding. Transformation is addressed as the extraordinary in the attainment of personal agency at the individual level, as organisational transformations and as transformations in wider local and national politics. This understanding of learning as political and potentially change-making adds to organisational learning, development management and social movement literature while expanding on the role of learning in social movement organisations.

description: Recent measurements performed with some direct dark matter detection experiments, e.g. CDMS-II and CoGENT (after DAMA/LIBRA), have unveiled a few events compatible with weakly interacting massive particles. The preferred mass range is around 10 GeV, with a quite large spin-independent cross section of $10^{-43}$-$10^{-41}\,{\rm cm^2}$. In this paper, we recall that a light dark matter particle with dominant couplings to quarks should also generate cosmic-ray antiprotons. Taking advantage of recent works constraining the Galactic dark matter mass profile on the one hand and on cosmic-ray propagation on the other hand, we point out that considering a thermal annihilation cross section for such low mass candidates very likely results in an antiproton flux in tension with the current data, which should be taken into account in subsequent studies.

Electrical conductivity in graphene with point defects

Publisher: name: arXiv

Subjects: subject: Disordered Systems and Neural Networks (cond-mat.dis-nn)
subject: FOS: Physical sciences

description: The electrical conductivity of graphene containing point defects is studied within the binary alloy model in its dependence on the Fermi level position at the zero temperature. It is found that the minimal conductivity value does not have a universal character and corresponds to the impurity resonance energy rather than to the Dirac point position in the spectrum. The substantial asymmetry of the resulting dependence of the conductivity on the gate voltage magnitude is attributed as well to this same shift of the conductivity minimum to the resonance state energy.
Dam to delta : visualizing landscapes of decarbonization in the Saaghii Naachii/Peace River region, Canada
Creators: name: Robb, Douglas
Publisher: name: University of British Columbia
Year: 2022

description: This dissertation analyzes how decarbonization in Canada is mutually co-constitutive with processes of landscape change. Drawing from interdisciplinary scholarship in human geography and landscape architecture, with a focus on digital technologies of landscape visualization and manipulation, this dissertation critically analyzes how contemporary decarbonization agendas (re)produce conditions of uneven development and socioecological instability. Chapter 2 explores how the historical formation of energy landscapes in Canada’s boreal region continues to influence design proposals for the low-carbon transition, often at the expense of Indigenous communities and fragile ecologies. Chapter 3 calls attention to the pervasive tendency to depict human impacts upon Earth though highly abstract and aestheticized visualizations; a deeply depoliticizing practice I term planetary voyeurism. Chapter 4 builds upon this critique through a meta-review of water-energy nexus visualizations: a resource governance framework that claims to comprehensively depict relational linkages between energy generation and water use, yet which often elides the spatial, temporal, and hydrosocial dimensions of landscape. Lastly, Chapter 5 investigates the potential to misread and depoliticize strategies of putative decarbonization which may not, in fact, be carbon neutral; particularly when the cumulative effects of broader landscape transformations are considered. Through these analyses, this dissertation advances a place-based approach to decarbonization grounded in three key arguments: 1) decarbonization is constituted by and through relational landscapes characterized by shifting social, political, and ecological interrelationships; 2) technology is a powerful instrument of landscape change, and innovative digital tools of landscape perception and visualization can mitigate (or reinforce) processes of spatial injustice through the production of low-carbon technonatures and socionatures; and 3) decarbonization presents an opportunity to decentre human beings in the design and construction of built environments. Taken together, these arguments seek to challenge conventional approaches to decarbonization, elucidate more just and inclusive energy transition pathways, and advance more-than-human approaches to the design of post-carbon futures.

description: The most fundamental complexes of free modules over a commutative ring are the Koszul complex, which is constructed from a vector (i.e., a 1-tensor), and the Eagon-Northcott and the Buchsbaum-Rim complexes, which are constructed from a matrix (i.e., a 2-tensor). The subject of this paper is a multilinear analogue of these complexes, which we construct from an arbitrary higher tensor. Our construction provides detailed new examples of minimal free resolutions, as well as a unifying view on a wide variety of complexes including: the Eagon-Northcott, Buchsbaum-Rim and similar complexes, the Eisenbud-Schreyer pure resolutions, and the complexes used by Gelfand-Kapranov-Zelevinsky and Weyman to compute hyperdeterminants. In addition, we provide applications to the study of pure resolutions and Boij-Soederberg theory, including the construction of infinitely many new families of pure resolutions and the first explicit description of the differentials of the Eisenbud-Schreyer pure resolutions.

Librations and Obliquity of Mercury from the BepiColombo radio-science and camera experiments

description: A major goal of the BepiColombo mission to Mercury is the determination of the structure and state of Mercury's interior. Here the BepiColombo rotation experiment has been simulated in order to assess the ability to attain the mission goals and to help lay out a series of constraints on the experiment's possible progress. In the rotation experiment pairs of images of identical surface regions taken at different epochs are used to retrieve information on Mercury's rotation and orientation. The idea is that from observations of the same patch of Mercury's surface at two different solar longitudes of Mercury the orientation of Mercury can be determined, and therefore also the obliquity and rotation variations with respect to the uniform rotation. The estimation of the libration amplitude and obliquity through pattern matching of observed surface landmarks is challenging. The main problem arises from the difficulty to observe the same landmark on the planetary surface repeatedly over the MPO mission lifetime, due to the combination of Mercury's 3:2 spin-orbit resonance, the absence of a drift of the MPO polar orbital plane and the need to combine data from different instruments with their own measurement restrictions. By assuming that Mercury occupies a Cassini state and that the spacecraft operates nominally we show that under worst case assumptions the annual libration amplitude and obliquity can be measured with a precision of respectively 1.4 arcseconds (as) and 1.0 as over the nominal BepiColombo MPO lifetime with about 25 landmarks for rather stringent illumination restrictions. The outcome of the experiment cannot be easily improved by simply relaxing the observational constraints, or increasing the data volume.

description: We demonstrate that topological defects in a rational conformal field theory can be described by a classifying algebra for defects - a finite-dimensional semisimple unital commutative associative algebra whose irreducible representations give the defect transmission coefficients. We show in particular that the structure constants of the classifying algebra are traces of operators on spaces of conformal blocks and that the defect transmission coefficients determine the defect partition functions.

On the Potential of the Reynolds Stress Approach to Model Convective Overshooting in Grids of Stellar Evolution Models
Creators: name: Kupka, Friedrich
Publisher: name: Zenodo
Year: 2021

description: Convection is one of the main physical processes probed by means of asteroseismology these days and it is a key topic of several workpackages within the PLATO mission. A lot of attention in this field is currently given to the parameter calibration of fairly simple models by means of 3D RHD numerical simulations or the direct use of the latter in asteroseismological analyses. However, this approach is not available to all situations of interest where convection plays a role in stellar mixing and in the evolution of the thermal structure of a star, particularly not for overshooting and mixing when they take place deeply inside a star. For such cases Reynolds stress models provide an interesting alternative. In this talk I will report on the potential of this method, also for future calculations of model grids for asteroseismology, and summarize earlier results and recent progress made with this approach.
Trap with ultracold neutrons as a detector of dark matter particles with long-range forces

description: The possibility of using a trap with ultracold neutrons as a detector of dark matter particles with long-range forces is considered. The basic advantage of the proposed method lies in possibility of detecting the recoil energy 10-7 eV. The restrictions on parameters of Yukawa type interaction potential between dark matter particles and a neutron are presented for different dark matter densities on the Earth. The assumption concerned with long-range interaction of dark matter particles and ordinary matter leads to a substantial enhancement of cross section at low energy. Consequently, there arises a possibility of capture and accumulation of dark matter in a gravitational field of the Earth. Rough estimation of accumulation of low-energy dark matter on the Earth is discussed. The first experimental restrictions for existence of dark matter with long-range forces on the Earth are presented.

description: Liquid water is generally assumed to be the most important factor for the emergence of life, and so a major goal in exoplanet science is the search for planets with water oceans. On terrestrial planets, the silicate mantle is a large source of water, which can be outgassed into the atmosphere via volcanism. Outgassing is subject to a series of feedback processes between atmosphere and interior, which continually shape both atmospheric composition, pressure, and temperature, as well as interior dynamics.

 We present the results of an extensive parameter study, where we use a newly developed 1D numerical model to simulate the coupled evolution of the atmosphere and interior of terrestrial exoplanets up to 5 Earth masses around
 Sun-like stars, with internal structures ranging from Moon- to Mercury-like. The model accounts for the main mechanisms controlling the global-scale, long-term evolution of stagnant-lid rocky planets (i.e. bodies without plate
 tectonics), and it includes a large number of atmosphere-interior feedback processes, such as a CO2 weathering cycle, volcanic outgassing, a water cycle between ocean and atmosphere, greenhouse heating, as well as the influence of a potential primordial H2 atmosphere, which can be lost through escape processes.

 We find that a significant majority of high-density exoplanets (i.e. Mercury-like planets with large cores) are able to outgas and sustain water on their surface. In contrast, most planets with intermediate, Earth-like densities either transition into a runaway greenhouse regime due to strong CO2 outgassing, or retain part of their primordial atmosphere, which prevents water from being outgassed. This suggests that high-density planets could be the most promising targets when searching for suitable candidates for hosting liquid water. (Presenter: Philipp Baumeister)

Stability in a population model without random deaths by the Verhulst factor

description: A large amount of population models use the concept of a carrying capacity. Simulated populations are bounded by invoking finite resources through a survival probability, commonly referred to as the Verhulst factor. The fact, however, that resources are not easily accounted for in actual biological systems makes the carrying capacity parameter ill-defined. Henceforth, we deem it essential to consider cases for which the parameter is unnecessary. This work demonstrates the possibility of Verhulst-free steady states using the Penna aging model, with one semelparous birth per adult. Stable populations are obtained by setting a mutation threshold that is higher than the reproduction age.

description: We show that the convex hull of a large i.i.d. sample from an absolutely continuous log-concave distribution approximates a predetermined convex body in the logarithmic Hausdorff distance and in the Banach-Mazur distance. For log-concave distributions that decay super-exponentially, we also have approximation in the Hausdorff distance. These results are multivariate versions of the Gnedenko law of large numbers, which guarantees concentration of the maximum and minimum in the one-dimensional case. We provide quantitative bounds in terms of the number of points and the dimension of the ambient space.

CMB Constraints on Primordial non-Gaussianity from the Bispectrum (f_{NL}) and Trispectrum (g_{NL} and τ_{NL}) and a New Consistency Test of Single-Field Inflation

description: We outline the expected constraints on non-Gaussianity from the cosmic microwave background (CMB) with current and future experiments, focusing on both the third (f_{NL}) and fourth-order (g_{NL} and τ_{NL}) amplitudes of the local configuration or non-Gaussianity. The experimental focus is the skewness (two-to-one) and kurtosis (two-to-two and three-to-one) power spectra from weighted maps. In adition to a measurement of τ_{NL} and g_{NL} with WMAP 5-year data, our study provides the first forecasts for future constraints on g_{NL}. We describe how these statistics can be corrected for the mask and cut-sky through a window function, bypassing the need to compute linear terms that were introduced for the previous-generation non-Gaussianity statistics, such as the skewness estimator. We discus the ratio A_{NL} = τ_{NL}/(6f_{NL}/5)^2 as an additional test of single-field inflationary models and discuss the physical significance of each statistic. Using these estimators with WMAP 5-Year V+W-band data out to l_{max}=600 we constrain the cubic order non-Gaussianity parameters τ_{NL}, and g_{NL} and find -7.4 < g_{NL}/10^5 < 8.2 and -0.6 < τ_{NL}/10^4 < 3.3 improving the previous COBE-based limit on τ_{NL} < 10^8 nearly four orders of magnitude with WMAP.

description: Excerpts from the report: Frozen food locker plants operating in the United States in January 1956 totaled 10,344. In number of plants Iowa led with 772, Washington came second with 668, and Minnesota third with 629. More than half the plants are located in the North Central States and about 15 percent in the Pacific Coast States. Frozen food lockers have proved to be one of the major keys to better food storage and better eating in the past two decades, particularly in rural communities. Locker plants are especially valuable in processing, storing and merchandising locally grown foods.
Geometric, Variational Discretization of Continuum Theories

description: This study derives geometric, variational discretizations of continuum theories arising in fluid dynamics, magnetohydrodynamics (MHD), and the dynamics of complex fluids. A central role in these discretizations is played by the geometric formulation of fluid dynamics, which views solutions to the governing equations for perfect fluid flow as geodesics on the group of volume-preserving diffeomorphisms of the fluid domain. Inspired by this framework, we construct a finite-dimensional approximation to the diffeomorphism group and its Lie algebra, thereby permitting a variational temporal discretization of geodesics on the spatially discretized diffeomorphism group. The extension to MHD and complex fluid flow is then made through an appeal to the theory of Euler-Poincaré systems with advection, which provides a generalization of the variational formulation of ideal fluid flow to fluids with one or more advected parameters. Upon deriving a family of structured integrators for these systems, we test their performance via a numerical implementation of the update schemes on a cartesian grid. Among the hallmarks of these new numerical methods are exact preservation of momenta arising from symmetries, automatic satisfaction of solenoidal constraints on vector fields, good long-term energy behavior, robustness with respect to the spatial and temporal resolution of the discretization, and applicability to irregular meshes.

description: Excerpts from the report: Many farmers and farm groups continue to be interested in handling some livestock through cooperative meatpacking plants. This desire to own and operate their own slaughtering, processing, and merchandising facilities increases during periods of low livestock prices and small feeding margins, although interest is not confined to such times. Present interest in cooperative meat-processing needs to be accompanied by adequate research to determine the feasibility of entering this business. Plant location, availability of livestock, competition, outlets for products, type of operation, support by local farmers, and available transportation need to be studied closely before making a definite decision to open a plant. Analysis of these factors should enable farmers to avoid some pitfalls and trouble spots responsible for failures in the past. Knowledge of what has caused failure, as given in the pages following, will also help in initial planning for such a venture.

Methodological issues with value-based decision-making (VBDM) tasks: The effect of trial wording on evidence accumulation outputs from the EZ drift-diffusion model

description: Most value-based decision-making (VBDM) tasks instruct people to make value judgements about stimuli using wording relating to consumption, however in some contexts this may be inappropriate. This study aims to explore whether variations of trial wording capture a common construct of value. This is a pre-registered experimental study with a within-subject design. Fifty-nine participants completed a two-alternative forced-choice task where they chose between two food images. Participants completed three blocks of trials: one asked which they would rather consume (standard wording), one asked which image they liked more, and one asked them to recall which image they rated higher during a previous block. We fitted the EZ drift-diffusion model to the reaction time and choice data to estimate evidence accumulation (EA) processes during the different blocks. There was a highly significant main effect of trial difficulty, but this was not modified by trial wording (F = 2.00, p = .11, ηp2 = .03, BF10 = .05). We also found highly significant positive correlations between the EA rates across task blocks (rs > .44, ps < .001). The findings provide initial validation of alternative wording in VBDM tasks that can be used in contexts where it may be undesirable to ask participants to make consummatory judgements.

description: Dust production is explored around 14 metal-poor ([Fe/H] = -1.91 to -0.98) giant stars in the Galactic globular cluster omega Centauri using new Spitzer IRS spectra. This sample includes the cluster's post-AGB and carbon stars and is thus the first representative spectral study of dust production in a metal-poor ([Fe/H] < -1) population. Only the more metal rich stars V6 and V17 ([Fe/H] = -1.08, -1.06) exhibit silicate emission, while the five other stars with mid-infrared excess show only a featureless continuum which we argue is caused by metallic iron dust grains. We examine the metallicity of V42, and find it is likely part of the metal-rich population ([Fe/H] ~ -0.8). Aside from the post-AGB star V1, we find no star from the cluster's bulk, metal-poor ([Fe/H] < -1.5) population - including the carbon stars - to be producing detectable amounts of dust. We compare the dust production to the stars' H-alpha line profiles obtained at the Magellan/Clay telescope at Las Campanas Observatory, finding pulsation shocking in the strongest pulsators (V6, V17 and V42), but evidence of outflow in all other stars. We conclude that the onset of dust production does not signify a fundamental change in the material leaving the star. Our data add to a growing body of evidence that metallic iron dominates dust production in metal-poor, oxygen-rich stars, but that dust is probably not the primary accelerant of winds in this mass-metallicity regime.

description: Excerpts from the report: This study presents results of a survey on effectiveness of a cooperative membership publication as determined by readership and its impact on patrons. So far as is known, no studies of this kind for co-ops have been published. A regular publication, distributed by a farmer cooperative to its members, is perhaps the chief means of communication between the cooperative and the farmers it serves. It follows, then, that the association's management wants to know whether the publication is doing an effective job. Do members read their cooperative paper? How regularly do they read it? What part of it do they read most? How do men and women compare in readership? Are there any appreciable differences in age, income, or educational levels among readers? What do readers think of the paper? What effect does it have on its readers? Does it influence their thinking and their actions? And if so, how? To find answers to this series of questions, Midland Cooperatives, Inc., Minneapolis, Minn., asked Farmer Cooperative Service, U. S. Department of Agriculture, to study the effectiveness of its membership newspaper -- Midland Cooperator. Farmer Cooperative Service undertook this study because findings also would have application to many cooperatives and others interested in membership publications.
Planetary Trojans - the main source of short period comets?

Year: 2010

description: We present a short review of the impact regime experienced by the terrestrial planets within our own Solar system, describing the three populations of potentially hazardous objects which move on orbits that take them through the inner Solar system. Of these populations, the origins of two (the Near-Earth Asteroids and the Long-Period Comets) are well understood, with members originating in the Asteroid belt and Oort cloud, respectively. By contrast, the source of the third population, the Short-Period Comets, is still under debate. The proximate source of these objects is the Centaurs, a population of dynamically unstable objects that pass perihelion between the orbits of Jupiter and Neptune. However, a variety of different origins have been suggested for the Centaur population. Here, we present evidence that at least a significant fraction of the Centaur population can be sourced from the planetary Trojan clouds, stable reservoirs of objects moving in 1:1 mean-motion resonance with the giant planets (primarily Jupiter and Neptune). Focusing on simulations of the Neptunian Trojan population, we show that an ongoing flux of objects should be leaving that region to move on orbits within the Centaur population. With conservative estimates of the flux from the Neptunian Trojan clouds, we show that their contribution to that population could be of order ~3%, while more realistic estimates suggest that the Neptune Trojans could even be the main source of fresh Centaurs. We suggest that further observational work is needed to constrain the contribution made by the Neptune Trojans to the ongoing flux of material to the inner Solar system, and believe that future studies of the habitability of exoplanetary systems should take care not to neglect the contribution of resonant objects (such as planetary Trojans) to the impact flux that could be experienced by potentially habitable worlds.

description: Through a detailed numerical investigation in three spatial dimensions, we demonstrate that long-lived time-dependent field configurations emerge dynamically during symmetry breaking in an expanding de Sitter spacetime. We investigate two situations: a single scalar field with a double-well potential and the bosonic sector of an SU(2) non-Abelian Higgs model. For the single scalar, we show that large-amplitude oscillon configurations emerge spontaneously and persist to contribute about 1.2% of the energy density of the universe. We also show that for a range of parameters, oscillon lifetimes are enhanced by the expansion and that this effect is a result of parametric resonance. For the SU(2) case, we see about 4% of the final energy density in oscillons.
