description: Scattering resonances play a central role in collision processes in physics and chemistry. They help build an intuitive understanding of the collision dynamics due to the spatial localization of the scattering wavefunctions. For resonances that are localized in the reaction region, located at short separation behind the centrifugal barrier, sharp peaks in the reaction rates are the characteristic signature, observed recently with state-of-the-art experiments in low-energy collisions. If, however, the localization occurs outside of the reaction region, mostly the elastic scattering is modified. This may occur due to above-barrier resonances, the quantum analogue of classical orbiting. By probing both elastic and inelastic scattering of metastable helium with deuterium molecules in merged-beam experiments, we differentiate between the nature of quantum resonances—tunnelling resonances versus above-barrier resonances—and corroborate our findings by calculating the corresponding scattering wavefunctions.

Food Security and Poverty

description: We construct a theoretical framework that puts the social worth of a microfinance organization (MFO) in terms of the depth, worth to users, cost to users, breadth, length, and scope of its output. We then analyze evidence of depth of outreach for five MFOs in Bolivia. Most of the poor households reached by the MFOs were near the poverty line- they were the richest of the poor. Group lenders had more depth of outreach than individual lenders. The urban poorest were more likely to be borrowers, but rural borrowers were more likely to be among the poorest.
Measurement of the W+W- Production Cross Section in ppbar Collisions at sqrt(s)=1.96 TeV using Dilepton Events

description: We present a measurement of the W+W- production cross section using 184/pb of ppbar collisions at a center-of-mass energy of 1.96 TeV collected with the Collider Detector at Fermilab. Using the dilepton decay channel W+W- -> l+l-vvbar, where the charged leptons can be either electrons or muons, we find 17 candidate events compared to an expected background of 5.0+2.2-0.8 events. The resulting W+W- production cross section measurement of sigma(ppbar -> W+W-) = 14.6 +5.8 -5.1 (stat) +1.8 -3.0 (syst) +-0.9 (lum) pb agrees well with the Standard Model expectation.

Subjects: Food Security and Poverty

description: Percentage increments in global crop and livestock yields are slowing. Percentage increments in global food demand may outstrip growth in food supply, causing food prices to rise to year 2040. Fortunately, the world seems headed for zero population growth by year 2100 and developed nations face no great economic, technological, or environmental hurdles in feeding themselves well. Sub-Saharan Africa and selected other developing countries face severe food security problems, however, but none severe enough to justify cutbacks in food production to bring world population in line with global carrying capacity. Food security is within reach of any country willing to address its socioinstitutional constraints and adopt the proven standard economic model.

description: The sky region containing the soft gamma-ray repeater SGR 1627-41 has been observed three times with XMM-Newton in February and September 2004. SGR 1627-41 has been detected with an absorbed flux of ~9x10^{-14} erg cm^{-2} s^{-1} (2-10 keV). For a distance of 11 kpc, this corresponds to a luminosity of ~3x10^{33} erg s^{-1}, the smallest ever observed for a Soft Gamma Repeater and possibly related to the long period of inactivity of this source. The observed flux is smaller than that seen with Chandra in 2001-2003, suggesting that the source was still fading and had not yet reached a steady quiescent level. The spectrum is equally well fit by a steep power law (photon index \~3.2) or by a blackbody with temperature kT~0.8 keV. We also report on the INTEGRAL transient IGR J16358-4726 that lies at ~10' from SGR 1627-41. It was detected only in September 2004 with a luminosity of ~4x10^{33} erg s^{-1} (for d=7 kpc), while in February 2004 it was at least a factor 10 fainter.

A special Davidsonian theory of events
Creators: name: Douglas, Keith
Publisher: name: University of British Columbia
Year: 2009

description: What is an event? What sort of object are they? How is a given event distinguished from other events and other objects? This thesis on science oriented metaphysics will take Davidson's account of events as its starting point to answer the above questions. It will develop this conception of events into one that is consistent with the special theory of relativity by updating its notions of change, cause and property. The new concept of a proper property, a generalization of the notion of an invariant, is introduced to solve some of these metascientific problems. Other features of the work include an analysis of the Lorentz force equation as it applies to one family of cases of causation, showing that a use of cause and effect to help individuate events cannot be complete until relativistic features are built into it. I propose that the conception of a proper property will also solve this worry over the nature of causation as it affects the issues of events above. In particular, it will attempt to solve a charge of circularity which has been leveled at Davidson's account. This property analysis also has the feature that it makes the account of events which started with Davidsonian inspiration (i.e. causes and effects are intimately connected to events) more like Kim's. Kim's account of events is modified on the grounds it does not do justice to our intuitions about changes and events.

description: We theoretically examine a system of Fermi degenerate atoms coupled to bosonic molecules by a Feshbach resonance, focusing on the superfluid transition to a molecular Bose-Einstein condensate dressed by Cooper pairs of atoms. This problem raises an interest because it is unclear at present whether bimodal density distributions observed recently in 40-K and 6-Li are due to a condensate of bosonic molecules or fermionic atom pairs. As opposed to 40-K, we find that any measurable fraction of above-threshold bosonic molecules are necessarily absent for the 6-Li system in question, which strongly implicates Cooper pairs as the culprit behind its bimodal distributions.

description: Industrialization of animal agriculture has created a battle groundpitting farmers against farmer, rural residents against large producers, and producer against consumer. The dilemma (tradeoff) of whether to have more small family farms or to lower food costs (with large farms) cannot easily be resolved. The answer is to internalize externalities (in waste disposal, odor, etc.), then to allow markets to work.
THE EQUIVALENCE OF EVOLUTIONARY GAMES AND DISTRIBUTED MONTE CARLO LEARNING

description: This paper presents a tight relationship between evolutionary game theory and distributed intelligence models. After reviewing some existing theories of replicator dynamics and distributed Monte Carlo learning, we make formulations and proofs of the equivalence between these two models. The relationship will be revealed not only from a theoretical viewpoint, but also by experimental simulations of the models by taking a simple symmetric zero-sum game as an example. As a consequence, it will be verified that seemingly chaotic macro dynamics generated by distributed micro-decisions can be explained with theoretical models.

Hermeneutic Phenomenology

description: Mindfulness, the intentional practice and result of paying attention, on purpose, to one’s moment-by-moment experience, without judgment (Kabat-Zinn, 1994), is a promising adjunct intervention for children addressing a variety of academic, behavioral, psychological, and somatic challenges. This qualitative study explored the child’s lived experience applying mindfulness skills to daily life to address a gap in the research, deepening a collective understanding of children’s lived experiences practicing mindfulness. This study aimed to fill this gap in the literature by exploring the essence of this phenomenon through the text of many children’s experiences. This work answered the research question, “What is the child’s experience of using mindfulness in daily life?” Hermeneutic phenomenology was the methodology for this work as it focused on the lived experience of children and the lens that my unique lived experience as a mindfulness educator and researcher offers. Thus, I hermeneutically analyzed 1,136 quotations from children found in my reflective teaching notes during 2014–2018, before this study’s inception, in response to the question, “How did you use your mindfulness in the last week?” This work offers a literature review that provides a foundational definition, an in-depth exploration of the components of mindfulness, the impact of mindfulness on the brain, developmental theory, trauma and ACEs, mindfulness interventions that take place both in and out of school, the involvement of parents and teachers in students learning mindfulness, awareness and regulation practices, the impact of regular practice, participant benefit, and the impact of self-selective participation. Thematic analysis, largely informed by van Manen’s (1990) work, brought to light findings relevant to these areas. This study’s findings established that children’s experiences with mindfulness allowed them to stay with their experiences, navigate circumstances and relationships, regulate emotional overwhelm, enact confidence and care, and thrive and blossom during the particular parameters of childhood. This work offers these findings alongside a detailed discussion. Mindfulness education for children benefits both children and the parents and teachers who nurture them. Findings from this work may offer support for social-emotional learning SEL work; implications for future research set these results in a context for the broader research community.

description: In this paper a collocation method based on the Bessel-hybrid functions is used for approximation of the solution of linear Fredholm-Volterra integro-differential equations (FVIDEs) under mixed conditions. First, we explain the properties of Bessel-hybrid functions, which are combination of block-pulse functions and Bessel functions of first kind. The method is based upon Bessel-hybrid approximations, so that to obtain the operational matrices and approximation of functions we use the transfer matrix from Bessel-hybrid functions to Taylor polynomials. The matrix equations correspond to a system of linear algebraic equations with the
unknown Bessel-hybrid coefficients. Present results and comparisons demonstrate our estimate have good degree of accuracy.
MODELING TIMBER SUPPLY, FUEL-WOOD, AND ATMOSPHERIC CARBON MITIGATION

Subjects: Environmental Economics and Policy

description: There is general agreement that global warming is occurring and that the main contributor to this probably is the buildup of green house gases, GHG, in the atmosphere. Two main contributors are the utilization of fossil fuels and the deforestation of many regions of the world. This paper examines a number of current issues related to mitigating the global warming problem through forestry. We use discrete time optimal control to model a simplified carbon cycle. The burning of fossil fuels increases atmospheric carbon while the burning of fuel-wood along with its forest source maintain an atmospheric carbon level. The standing timber in the forests is a carbon sink, as are wood buildings and structures, and fossil fuel in the ground. Through time the buildings and structures decay and release carbon to the atmosphere. We also present a numerical example to help illustrate the characteristics of the model. The conclusions are that the forest sector can have a significant impact.

description: The notion of a reservation value is a key feature of most contemporary dynamic and stochastic models of land development. It is clear that the magnitude of the reservation value has a fundamental bearing on the decision to develop or preserve land. This notwithstanding, many papers that analyze land development in a dynamic and stochastic setting treat a landowner's reservation value as an exogenous variable. Therefore, the purpose of this paper is to endogenize the reservation value in the context of a model of land development over time and under uncertainty. Our analysis shows that the optimal reservation value is the solution to a specific maximization problem. In addition, we also show that there exist theoretical circumstances in which the optimal reservation value is unique.

description: This paper concerns spectral stability and time evolution of $N$-solitons in the KdV hierarchy with mixed commuting time flows. Spectral stability problem is analyzed by using a pair of self-adjoint operators with finite numbers of negative eigenvalues. We show that the absence of unstable eigenvalues in the stability problem is related to the absence of negative eigenvalues of these operators in the constrained function spaces. Time evolution of $N$-solitons is uniquely characterized from the inverse scattering transform technique.

"Now look, the picture shows" : the visualization of disordered eating in Victorian children’s literature
Creators: name: Brocklebank, Lisa
Publisher: name: University of British Columbia
Year: 2009

description: This thesis explores the myriad ways in which the apparently unrelated discourses of medicine, fiction and photography intertwine in the depiction of disordered eating. It examines the medical literature of the physician William Withey Gull, who first diagnosed anorexia nervosa as a discrete disease in 1874, alongside select works of Victorian children's fiction. In analysing Gull's "Anorexia Nervosa (Apepsia Hysterica, Anorexia Hysterica)" (1874) and "Anorexia Nervosa" (1888), Mary De Morgan's "A Toy Princess" (1877), Dr. Heinrich Hoffmann's "The Story of Augustus Who Would Not Have Any Soup" (1845), Christina Rossetti's "Goblin Market" (1862) and Lewis Carroll's Alice's Adventures in Wonderland (1865), the thesis considers how these texts make use of a photographic sensibility to visualize the oral consumer, the extent to which Gull's medical documents could have been influenced by previous fictional depictions of disordered eating and, finally, how a visual order informed by the photographic image in fact provided the necessary milieu for the emergence of modern forms of disordered eating.

description: The set of all metrics that can be placed on a given manifold defines an infinite-dimensional `superspace' that can itself be imbued with the structure of a Riemannian manifold. Geodesic distances between points on Met$(M)$ measure how close two different metrics over $M$ are to one another. Restricting our attention to only those metrics that describe physical black holes, these distances may therefore be thought of as measuring the level of geometric similarity between different black hole structures. This allows for a systematic quantification of the extent to which a black hole, possibly arising as an exact solution to a theory of gravity extending general relativity in some way, might be `non-Kerr'. In this paper, a detailed construction of a superspace for stationary black holes with an arbitrary number of hairs is carried out. As an example application, we are able to strengthen a recent claim made by Konoplya and Zhidenko about which deviation parameters describing a hypothetical, non-Schwarzschild black hole are likely to be most relevant for astrophysical observables.

description: A deep, continuum-subtracted, image of NGC 7293 has been obtained in the light of the Halpha+[N II] emission lines. New images of two filamentary halo stuctures have been obtained and the possible detection of a collimated outflow made. Spatially resolved, longslit profiles of the Halpha+[N II] lines have been observed across several of these features with the MES combined with the SPM 2.1m telescope; these are compared with the [N II]6584, [O III]5007, HeII 6560 and Halpha profiles obtained over the nebular core. The central HeII emission is originating in a ~0.34pc diameter spherical volume expanding at <=12km/s which is surrounded, and partially coincident with an [O III] emitting inner shell expanding at 12km/s. The bright helical structure surrounding this inner region is modelled as a bi-polar nebula with lobe expansions of 25km/s whose axis is tilted at 37deg to the sight line but with a toroidal waist itself expanding at 14 km/s. These observations are compared with the expectations of the interacting two winds model for the formation of PNe. Only after the fast wind has switched off could this global velocity structure be generated. Ablated flows must complicate any interpretation. It is suggested that the clumpy nature of much of the material could play a part in creating the radial `spokes' shown here to be apparently present close to the central star. These `spokes' could in fact be the persistant tails of cometary globules whose heads have now photo-evaporated completely. A halo arc projecting from the north-east of the bright core has a conterpart to the south-east. Anomolies in the position-velocity arrays of line profiles could suggest that these are part of an expanding disc not aligned with the central helical structure though expanding bi-polar lobes along a tilted axis are not ruled out.

description: The stars that end their lives as supernovae (SNe) have been directly observed in only a handful of cases, due mainly to the extreme difficulty in identifying them in images obtained prior to the SN explosions. Here we report the identification of the progenitor for the recent Type II-plateau (core-collapse) SN 2005cs in pre-explosion archival images of the Whirlpool Galaxy (M51) obtained with the Hubble Space Telescope (HST) Advanced Camera for Surveys (ACS). From high-quality ground-based images of the SN from the Canada-France-Hawaii Telescope, we precisely determine the position of the SN and are able to isolate the SN progenitor to within 0".04 in the HST/ACS optical images. We further pinpoint the SN location to within 0".005 from HST/ACS ultraviolet images of the SN, confirming our progenitor identification. From photometry of the SN progenitor obtained with the pre-SN ACS images, and also limits to its brightness in pre-SN HST/NICMOS images, we infer that the progenitor is a red supergiant star of spectral type K0--M3, with initial mass 7--9 Msun. We also discuss the implications of the SN 2005cs progenitor identification and its mass estimate. There is an emerging trend that the most common Type II-plateau SNe originate from low-mass supergiants 8--15 Msun.

The reported semiconducting SWCNT have normal state differential conductance up to $3e^2/h$ and exhibit clear Fabry-Perot interference patterns in the bias spectroscopy plot. We observed subharmonic gap structure in the differential conductance and a distinct peak in the conductance at zero bias which is interpreted as a manifestation of a supercurrent. The gate dependence of this supercurrent as well as the excess current are examined and compared to a coherent theory of superconducting point contacts with good agreement.

description: We study here what it means for the Universe to be nearly flat, as opposed to exactly flat. We give three definitions of nearly flat, based on density, geometry and dynamics; all three definitions are equivalent and depend on a single constant flatness parameter epsilon that quantifies the notion of nearly flat. Observations can only place an upper limit on epsilon, and always allow the possibility that the Universe is infinite with k=-1 or finite with k=1. We use current observational data to obtain a numerical upper limit on the flatness parameter and discuss its implications, in particular the "naturalness" of the nearly flat Universe.

description: Implicit (hedonic) producer prices for fiber strength uniformity were estimated for the southwest U.S. cotton market using seemingly unrelated regression and market sales data from 1983/84 and 1984/85, Fiber strength and length uniformity had significant effects on the price of cotton, but price was less responsive to both attributes than anticipated. Producer prices were most responsive to fiber length and micronaire and least responsive to color and strength. The market at the producer level appears to be making effective price adjustments with respect to factors such as fiber color, trash content, micronaire, fiber length, and location, but strength and length uniformity premiums and discounts are smaller than those paid by end users.

description: Deep surveys with Atacama Large Millimeter Array (ALMA) have uncovered a population of dusty star-forming galaxies which are faint or even undetected at optical to near-infrared wavelengths. Their faintness at short wavelengths makes detailed characterization of the population challenging. Here we present a spectroscopic redshift identification and characterization of one of such near-infrared-dark galaxy discovered by an ALMA deep survey. Detection of [CI](1-0) and CO(4-3) emission lines determines the precise redshift of the galaxy, ADF22.A2, to be z=3.9913+/-0.0008. On the basis of multi-wavelength analysis, ADF22.A2 is found to be a massive, star-forming galaxy with stellar mass Mstar = $1.1_{-0.6}^{+1.3}$ x 10^{11} Msun and SFR = $430_{-150}^{+230}$ Msun/yr. The molecular gas mass is derived to be M ($H_2$) = 5.9 +/- 1.5x10^{10} Msun, indicating a gas fraction of ~35%, and the ratios of $L_{\rm [CI](1-0)}/L_{\rm IR}$ and $L_{\rm [CI](1-0)}/L_{\rm CO(4-3)}$ suggests that the nature of the interstellar medium in ADF22.A2 is in accordance with those of other bright submillimeter galaxies. The properties of ADF22.A2, including redshift, star-formation rate, stellar mass, and depletion time scale (tau~0.1-0.2 Gyr), also suggest that ADF22.A2 has the characteristics expected for the progenitors of quiescent galaxies at z>3. Our results demonstrate the power of ALMA contiguous mapping and line scan to obtain an unbiased view of galaxy formation in the early Universe.

Almost periodic functions, constructively
Creators: name: Spitters, Bas
Publisher: name: arXiv

description: The almost periodic functions form a natural example of a non-separable normed space. As such, it has been a challenge for constructive mathematicians to find a natural treatment of them. Here we present a simple proof of Bohr's fundamental theorem for almost periodic functions which we then generalize to almost periodic functions on general topological groups.

description: We studied the commensurate semi-fluxon oscillations of Josephson flux-flow (JFF) in a Bi-2212 stacked structures near $T_c$ as a probe of melting of Josephson vortex lattice (JVL). We found that oscillations exist above 0.5T. The amplitude of oscillations is found to decrease gradually with temperature and to turn to zero without any jump at $T=T_0$, 3.5K below the resistive transition temperature $T_c$ indicating the phase transition of the second order. This characteristic temperature $T_0$ is identified as the Berezinskii-Kosterlitz-Thouless (BKT) transition temperature, $T_{BKT}$, in elementary superconducting layers of Bi-2212 at zero magnetic field. On the base of these facts we infer that melting of triangular Josephson vortex lattice occurs via the BKT phase with formation of characteristic flux loops containing pancake vortices and anti-vortices. The $B-T$ phase diagram of the BKT phase found out from our experiment is consistent with theoretical predictions.

description: Origami design principles are scale invariant and enable direct miniaturization of origami structures provided the sheets used for folding have equal thickness to length ratios. Recently, seminal steps have been taken to fabricate microscale origami using unidirectionally actuated sheets with nanoscale thickness. Here, we extend the full power of origami-inspired fabrication to nanoscale sheets by engineering bidirectional folding with 4 nm thick atomic layer deposition (ALD) SiNx-SiO2 bilayer films. Strain differentials within these bilayers result in bending, producing microscopic radii of curvature. We lithographically pattern these bilayers and localize the bending using rigid panels to fabricate a variety of complex micro-origami devices. Upon release, these devices self-fold according to prescribed patterns. Our approach combines planar semiconductor microfabrication methods with computerized origami design, making it easy to fabricate and deploy such microstructures en masse. These devices represent an important step forward in the fabrication and assembly of deployable micromechanical systems that can interact with and manipulate micro- and nanoscale environments.

description: A new learning algorithm for Evolving Cascade Neural Networks (ECNNs) is described. An ECNN starts to learn with one input node and then adding new inputs as well as new hidden neurons evolves it. The trained ECNN has a nearly minimal number of input and hidden neurons as well as connections. The algorithm was successfully applied to classify artifacts and normal segments in clinical electroencephalograms (EEGs). The EEG segments were visually labeled by EEG-viewer. The trained ECNN has correctly classified 96.69% of the testing segments. It is slightly better than a standard fully connected neural network.

Relativity, nonextensivity, and extended power law distributions

description: A proof of the relativistic $H$-theorem by including nonextensive effects is given. As it happens in the nonrelativistic limit, the molecular chaos hypothesis advanced by Boltzmann does not remain valid, and the second law of thermodynamics combined with a duality transformation implies that the q-parameter lies on the interval [0,2]. It is also proved that the collisional equilibrium states (null entropy source term) are described by the relativistic $q$-power law extension of the exponential Juttner distribution which reduces, in the nonrelativistic domain, to the Tsallis power law function. As a simple illustration of the basic approach, we derive the relativistic nonextensive equilibrium distribution for a dilute charged gas under the action of an electromagnetic field $F^{μν}$. Such results reduce to the standard ones in the extensive limit, thereby showing that the nonextensive entropic framework can be harmonized with the space-time ideas contained in the special relativity theory.

description: Compared to their urban counterparts, the rural poor are more likely to be employed, more apt to be members of married-couple families, less likely to be children, less likely to be minority, and more likely to have assets but a negative income. This paper examines poverty rates and factors that affect mobility in and out of poverty among major categories of the rural poor. Particular attention is paid to farm workers and the rural farm population in the South. It endeavors to identify both structural conditions that perpetuate rural poverty and government interventions that ameliorate human suffering and break the cycle of poverty reproduction.
Naeen : aspects of environmental response
Creators: name: Fazli, Mojgan
Publisher: name: University of British Columbia
Year: 2009

description: There are numerous studies dealing with Iranian history and culture, but only a few of them have discussed the architectural forms found in cities and towns. Consequently, there is a need for more analytical studies that can explain the processes by which these architectural forms and cities have developed throughout Iranian history. The main objective of this study is to use a multimedia format to study different types of information. A second objective is to show the role of water in the formation of one Iranian city, Naeen. I have used my own field experience in Iran as well as the works of others to explain the path of water as it influenced the formation of one of the oldest extant cities of Iran's dry arid region, Naeen. Multimedia presentations on this compact disc use slides, video sequences and 3D models combined with text, all of which have been programmed into an interactive environment.

description: We compute $e^{-AN}$ corrections to the Gross-Taylor 1/N expansion of the paritition function of two-dimensional SU(N) and U(N) Yang Mills theory. We find a very similar structure of mixing between holomorphic and anti-holomorphic sectors as that described by Vafa for the 1/N expansion. Some of the non-perturbative terms are suggestive of D-strings wrapping the $T^2$ of the 2dYM but blowing up into a fuzzy geometry by the Myers effect in the directions transverse to the $T^2$.

description: Empirical analysis of manufacturing plant location requires the use of a single industrial site quality measure. Under hedonic price theory, the price of industrial sites can be explained by their quality characteristics. The estimated site price is included with ten other location factors in an ordered, categorical logit model of plant attraction to Georgia counties. The results inform public decision-makers of the relative impact of site location factors and how changes in location factors can alter the probability of attracting a manufacturing plant.

description: We study how manifestations of strong electron-phonon interaction (EPI) depend on the carrier concentration by solving the two-dimensional Holstein model for the spin-polarized fermions using an approximation free bold-line diagrammatic Monte Carlo (BDMC) method. We show that the strong EPI, obviously present at very small Fermion concentration, is masked by the Fermi blockade effects and Migdal's theorem to the extent that it manifests itself as moderate one at large carriers densities. Suppression of strong EPI fingerprints is in agreement with experimental observations in doped high temperature superconductors

description: The main results of an experimental work on co-gasification of Colombian biomass/coal blends in a fluidized bed working at atmospheric pressure are reported in this paper. Several samples of blends were prepared by mixing 6–15wt% biomass (sawdust, rice or coffee husk) with coal. Experimental assays were carried out by using mixtures of different steams/blends (Rvc) and air/blend (Rac) ratios showing the feasibility to implement co-gasification as energetic alternative to produce fuel gas to heat and to generate electricity and the possibility of converting clean and efficiently the refuse coal to a low-heating value gas.
