description: The parameterization of small-scale turbulent fluctuations in convective systems and in the presence of strong stratification is a key issue for many applied problems in oceanography, atmospheric science and planetology. In the presence of stratification, one needs to cope with bulk turbulent fluctuations and with inversion regions, where temperature, density -or both- develop highly non-linear mean profiles due to the interactions between the turbulent boundary layer and the unmixed -stable- flow above/below it. We present a second order closure able to cope simultaneously with both bulk and boundary layer regions, and we test it against high-resolution state-of-the-art 2D numerical simulations in a convective and stratified belt for values of the Rayleigh number, up to Ra = 10^9. Data are taken from a Rayleigh-Taylor system confined by the existence of an adiabatic gradient.

description: Excerpts from the report Introduction: Agricultural cooperative statistics are collected annually and published to provide information on the position and trends among the Nation’s farmer, rancher, and fishery cooperatives. These statistics are used for cooperative benchmarking, research, technical assistance, education, planning, and public policy. The collection, analysis, and dissemination of cooperative statistics by the United States Department of Agriculture (USDA) are authorized by The Cooperative Marketing Act of 1926. This report presents agricultural cooperative statistics for 2019 in table and chart format and consists of six sections: (I) overall summary cooperative statistics; (II) number of cooperatives, memberships, and employees; (III) business volume by State, and losses; (IV) Top 100 cooperatives; (V) benchmark statistics for cooperative comparisons; and (VI) cooperative statistical trends. Selected highlights are provided at the beginning of each section, and associated tables follow.
On amortized inference in large-scale simulators
Creators: name: Naderiparizi, Saeid
Publisher: name: University of British Columbia
Year: 2020

description: Motivated by the problem of amortized inference in large-scale simulators, we introduce a probabilistic programming library that brings us closer to this goal. This library enables us to perform Bayesian inference on any simulator written in a wide variety of programming languages, with minimal modification to the simulator's source code. However, there are challenges in achieving this goal in its most general meaning. In particular, we address the obstacles caused by unbounded loops. Existing approaches to amortized inference in probabilistic programs with unbounded loops can produce estimators with infinite variance. An instance of this is importance sampling inference in programs that explicitly include rejection sampling as part of the user-programmed generative procedure. We develop a new and efficient amortized importance sampling estimator. We prove finite variance of our estimator and empirically demonstrate our method's correctness and efficiency compared to existing alternatives on generative programs containing rejection sampling loops and discuss how to implement our method in a generic probabilistic programming framework.

description: We compute the transition temperature $T_c$ and the Ginzburg temperature $T_{\rm G}$ above $T_c$ near a quantum critical point at the boundary of an ordered phase with a broken discrete symmetry in a two-dimensional metallic electron system. Our calculation is based on a renormalization group analysis of the Hertz action with a scalar order parameter. We provide analytic expressions for $T_c$ and $T_{\rm G}$ as a function of the non-thermal control parameter for the quantum phase transition, including logarithmic corrections. The Ginzburg regime between $T_c$ and $T_{\rm G}$ occupies a sizable part of the phase diagram.

description: In summary, as with the Schafer and Shippee study, our preliminary data on age identity in the oldest old subjects show that feeling much younger than one’s chronological age has a great impact on one’s perceptions about one’s physical health, well being, and now cognition. Disposition about cognitive aging is more optimistic with younger age identities, and actual cognitive performance is elevated. Many older individuals in our study agreed with the wisdom espoused by Mr. Lincoln that “…in the end, it's not the years in your life that count. It's the life in your years.”

description: Report Summary: Mishandling and packaging deficiencies were the major causes of damage to dry groceries in a 1985 survey of warehousing operations by the Agricultural Marketing Service, U.S. Department of Agriculture. The 10 warehouses surveyed employed a variety of systems from conventional to fully automated. Recouping practices varied from almost nonexistent to extensive salvaging and repacking. Disposition of recouped merchandise ranged from selling at full price to donating the item to charity. Damage reduction efforts varied similarly from none to regularly scheduled employee meetings and incentive programs. Few firms are fully aware of actual costs of damage, i.e., the many indirect costs over and above the value of the product lost. Many means are available to reduce damage; not all of them are economically feasible or applicable for any given firm. Suppliers must be willing to cooperate with their customers in resolving obvious packaging problems.

description: We postulate the applicability of the general form-invariance principle in special relativity. It is shown that this principle holds in classical mechanics. Some examples of transformations between the reference frames which satisfy this principle are considered. A new transformation is proposed for a transition from a uniformly rotating reference frame to a reference frame whose origin is shifted from the rotation axis. Another possible formulation of this principle is given for the case of stationary rigid reference frames which differ from one another only by the position of the origin.

Generalized distillability conjecture and generalizations of Cauchy-Bunyakovsky-Schwarz inequality and Lagrange identity

description: Let rho_k, k=1,2,...,m, be the critical Werner state in a bipartite d_k by d_k quantum system, i.e., the one that separates the 1-distillable Werner states from those that are 1-indistillable. We propose a new conjecture (GDC) asserting that the tensor product of rho_k is 1-indistillable. This is much stronger than the familiar conjecture saying that a single critical Werner state is indistillable. We prove that GDC is true for arbitrary m provided that d_k is bigger than 2 for at most one index k. We reformulate GDC as an intriguing inequality for four arbitrary complex hypermatrices of type d_1 x ... x d_m. This hypermatrix inequality is just the special case n=2 of a more general conjecture (CBS conjecture) for 2n arbitrary complex hypermatrices of the same type. Surprisingly, the case n=1 turns out to be quite interesting as it provides hypermatrix generalization of the classical Lagrange identity. We also formulate the integral version of the CBS conjecture and derive the integral version of the hypermatrix Lagrange identity.

The spin-orbit Hamiltonian completes the knowledge of Hamiltonians up to and including 2.5PN for the general relativistic three-body problem. The new Hamiltonians include highly nontrivial three-body interactions, in contrast to the leading order consisting of two-body interactions only. This may be important for the study of effects like Kozai resonances in mergers of black holes with binary black holes.

description: Excerpts from the report: The objective of this report is to examine the possibility of developing a regional farmers' market in northern Kentucky. The proposed market would be a center of commerce where farmers from the region could sell their production of fruits, vegetables, and other related agricultural commodities. In addition to serving the farmers of northern Kentucky, the market could also provide producers, regionally and state-wide, a cost-efficient means to market their products. At the present time no facility of this nature or potential scope exists in the Commonwealth. All of the pertinent secondary and primary data collected were systemically compiled and included in this report to provide officials with a reliable document upon which to base their decision whether or not a regional farmers' market should be built in northern Kentucky.
Educating without bannisters : Hannah Arendt on thinking, willing, and judging
Creators: name: Jensen, Jill Michelle
Publisher: name: University of British Columbia
Year: 2020

description: As a school principal I make explicit and tacit judgments that affect (often vulnerable) other people each day, a responsibility for which I have little preparation or institutional encouragement. Indeed, exercising judgment has become especially difficult in modernity because of the absence of secure traditions for guidance. Here I draw on Hannah Arendt’s ideas about judging developed in response to the Holocaust that—while not consistent, congruent, or even complete—point to powerful ways to think and judge in a world that lacks ethical bannisters. I begin by outlining Arendt’s efforts to reimagine the ancient Athenian vita activa for a modern pluralistic democratic society. In The Human Condition Arendt describes its destruction and begins to develop democratic remedies based on reconceiving the relationship between public and private spaces—an effort that was severely challenged by the trial of Adolph Eichmann. Particularly alarming to Arendt was the Nazis’ success at destroying the public and private realms, eliminating the conditions she deemed essential for ethical-political judging. In response, Arendt begins to reimagine the vita comtemplativa based on her iconoclastic interpretations of Aristotle and Kant. She drafts the first two sections of The Life of the Mind, Thinking and Willing, before succumbing to a heart attack in 1975. Instead of thinking as searching for answers, she understands thinking as continuous questioning or wondering and as introspectively searching for meaning. Instead of willing as implementing self-sovereignty (as in will-power), she develops the idea of a non-sovereign Will that exercises freedom understood as responsible autonomy in a plural, contingent world. While Arendt never wrote the final section on judging, she did leave various pieces that point to important considerations involved in making ethical-political judgments in “dark times,” that is, when the required private and public spaces for democratic action are absent. Some considerations include: Seeing the individual person; judging as a spectator; choosing our company carefully; finding suitable examples; and imagining possible appraisals. Throughout my thesis I use Arendt’s ideas to understand my own experience and point to implications for my practice.

description: Many-body physics is traditionally concerned with systems of interacting massive particles. Recent studies of effective interactions between photons, induced in the circuit QED architecture by coupling the microwave field to superconducting qubits, have paved the way for photon-based many-body physics. We derive the magnitude and intrinsic signs of photon hopping amplitudes in such circuit QED arrays. For a finite, ring-shaped Jaynes-Cummings lattice exposed to a synthetic gauge field we show that degeneracies in the single-excitation spectrum emerge, which can give rise to strong correlations for the interacting system with multiple excitations. We calculate the homodyne transmission for such a device, explain the generalization of vacuum Rabi splittings known for the single-site Jaynes-Cummings model, and identify fingerprints of interactions beyond the linear response regime.

description: Immersive reality technologies such as Virtual Reality(VR) and Augmented Reality (AR) offer interesting opportunities in the visualisation of data. However, despite their recent popularity, research in regards to graph data visualisation using these technologies is limited, especially so for hierarchical graphs. Pedigrees, a specific type of hierarchical data that model the breeding of plant varieties within a species are a novel and interesting application area of these visualisations. We present a study on the appropriate way to visualise pedigree graph data within immersive reality. We develop a novel immersive reality application that incorporates innovative interaction techniques, and model six different graph layouts based on a hierarchical application of existing graph layout techniques. These graph layouts include the planar, cylinder, floor, sphere, cone (force directed) and vase. These six layouts were compared with a within-subjects user study measuring task accuracy, task completion time, and qualitative sentiment from the user. The results of the study did not indicate any statistically significant superior graph layout in regards to task accuracy and task completion time. However, we found that the floor layout performed the poorest in all metrics measured. These findings indicate that most 3D layouts achieve very similar performance with not only each other but the 2D baseline planar view in regards to task accuracy or task completion time. However, the sphere layout was the most positively received by the users, even more so than the 2D baseline planar layout based on the qualitative questionnaire. As such, the advantage that is possessed by some 3D layouts (but not all) such as the sphere is how they are more positively perceived.

The right-moving sector is non-supersymmetric at the massless level, but is characterized by MSDS symmetry, which ensures boson/fermion degeneracy of the right-moving massive levels. Finite temperature configurations, which are free of Hagedorn instabilities, are constructed in the presence of non-trivial "gravito-magnetic" fluxes. These fluxes inject non-trivial winding charge into the thermal vacuum and restore the thermal T-duality symmetry associated with the Euclidean time circle. Thanks to the unbroken right-moving MSDS symmetry, the one-loop string partition function is exactly calculable beyond any alpha'-approximation. At the self-dual point new massless thermal states appear, sourcing localized spacelike branes, which can be used to connect a contracting thermal Universe to an expanding one. The resulting bouncing cosmology is free of any curvature singularities and the string coupling remains perturbative throughout the cosmological evolution.

description: Cosmic ray protons generate gamma-rays, neutrinos, and secondary electrons and positrons (e+/-) through pion-producing collisions with gas atoms. Any synchrotron or Inverse Compton (IC) radiation from secondary e+/- is therefore accompanied by pionic gamma-rays. Using the extragalactic gamma-ray background, we constrain the contribution of secondary e+/- to the cosmic radio, X-ray, and soft gamma-ray backgrounds. These bounds depend on the unknown hadronic contribution to the gamma-ray background and the backgrounds' source redshifts. With our assumptions, we find that IC-upscattered light from secondaries is

Inattentional Blindness: Neural Correlates and Theoretical Progress

description: Consciousness has remained one of the most perplexing enigmas of science and philosophy. Modern neuroscientific research seeks to understand how consciousness emerges within biological systems through identifying the necessary mechanisms that enable sensory information to be consciously experienced. Inattentional blindness (IB), the failure to notice something right in front of you, offers a profound means of studying consciousness, as it highlights the indistinct boundary between the conscious and the unconscious. The primary goal of the current thesis was to contribute to a scientific understanding of consciousness through advancing knowledge on IB. To this end, two reviews and four empirical studies were conducted. The first review provides a qualitative synthesis of empirical literature on IB that has employed neuroscientific methodology. Findings suggest that neural correlates of consciousness under conditions of IB may favour early sensory views of consciousness, however more research is needed. The second review provides a systematic review of the behavioural literature on IB, with focus on its two leading theories. Findings highlight that no theory can yet fully account for IB, and a model of IB is proposed based on the partial awareness hypothesis. Study one investigates the relation between alpha-band neural activity and IB via electroencephalography (EEG). Results indicate that a reduction in alpha activity in the pre- and post-stimulus interval correlates with consciousness of the critical stimulus during IB. Study two employs transcranial alternating current stimulation (tACS) to examine a causal role of alpha activity in IB. Findings indicate that, relative to control conditions, those stimulated at alpha frequency were more likely to be subject to IB. Study three extends on study two by implementing auditory tone trains at various frequencies during IB. Results show no difference in rates of IB based on auditory tone frequency. Study four then addresses the degree to which semantic processing, as indexed via the N400, can occur under conditions of IB. Findings show that no significant N400 activity is observed when the eliciting stimuli are rendered unconscious via IB. Overall, the implications of the current thesis are that alpha activity has a reliable, and potentially causal, relationship with IB; that a coherent explanation of IB is yet to exist, but may be found in reconsidering the traditional view of visual consciousness more broadly; and that the endowment of meaning to sensory information may be a key function of consciousness.

description: We build a simple, {\it top-down} model for the gas density and temperature profiles for galaxy clusters. The gas is assumed to be in hydrostatic equilibrium along with a component of non-thermal pressure taken from simulations and the gas fraction approaches the cosmic mean value only at the virial radius or beyond. The free parameters of the model are the slope and normalisation of the concentration-mass relation, the gas polytropic index, and slope and normalisation of the mass-temperature relation. These parameters can be fixed from X-Ray and lensing observations. We compare our gas pressure profiles to the recently proposed `Universal' pressure profile by \cite{Arnaud09} and find very good agreement. We find that the Sunyaev-Zel'dovich Effect (SZE) scaling relations between the integrated SZE flux, $Y$, the cluster gas temperature, $T_{\rm sl}$, the cluster mass, $M_{\rm tot}$, and the gas mass, $M_{\rm gas}$ are in excellent agreement with the recently observed $r_{2500}$ SZE scaling relations by \cite{Bonamente08} and $r_{500}$ relation by \cite{Arnaud09}. The gas mass fraction increases with cluster mass and is given by $f_{\rm gas}(r_{500}) = 0.1324 + 0.0284 \,\rm{log}\, (\frac{M_{500}}{10^{15}h^{-1}M_\odot})$. This is within $10%$ of observed $f_{\rm gas}(r_{500})$. The consistency between the global properties of clusters detected in X-Rays and in SZE shows that we are looking at a common population of clusters as a whole, and there is no deficit of SZE flux relative to expectations from \xr scaling properties. Thus, it makes it easier to compare and cross-calibrate clusters from upcoming \xr and SZE surveys.

description: The leaves of various Pyrrosia species have been shown to possess antibacterial and anti-inflammatory properties and have been widely used in traditional Chinese medicine. However, few studies have investigated the active components of Pyrrosia plants. In this study, flavonoids and phenolic acids of four Pyrrosia species were isolated and identified using Ultra Performance Liquid Chromatography-Quadrupole-Exactive Orbitrap Mass Spectrometry (UPLC-MS/MS). The antioxidant properties were evaluated using 1,1-diphenyl-2-picrylhydrazyl (DPPH), reducing power assay, hydroxyl radical scavenging assay, phosphomolybdenum antioxidant activity, and in vivo antioxidant activity assay. UPLC-MS/MS showed a total of 19 flavonoid compounds were indentified, among of which, eriodictyol-7-O-glucoside (8) and kaempferol-3-O-rutinoside (12) were isolated from Pyrrosia for the first time. Apigenin (16), genkwanin (18) and ursolic acid (19) were also isolated from Pyrrosia gralla for the first time. This study was the first to determine the total flavonoid and phenolic compound content of Pyrrosia extracts and confirm their high antioxidant properties.

Star Formation in Disk Galaxies. II. The Effect of Star Formation and Photoelectric Heating on the Formation and Evolution of Giant Molecular Clouds

description: We investigate the effect of star formation and diffuse photoelectric heating on the properties of giant molecular clouds (GMCs) formed in high resolution (~< 10 pc) global (~ 20 kpc) simulations of isolated Milky Way-type galaxy disks. The clouds are formed through gravitational fragmentation and structures with densities n_H>=100cm^-3 are identified as GMCs. Between 1000-1500 clouds are created in the simulations with masses M > 10^5 Msolar and 180-240 with masses M > 10^6 Msolar in agreement with estimates of the Milky Way's population. We find that the effect of photoelectric heating is to suppress the fragmentation of the ISM, resulting in a filamentary structure in the warm gas surrounding clouds. This environment suppresses the formation of a retrograde rotating cloud population, with 88% of the clouds rotating prograde with respect to the galaxy after 300 Myr. The diffuse heating also reduces the initial star formation rate, slowing the conversation of gas into stars. We therefore conclude that the interstellar environment plays an important role in the GMCs evolution. Our clouds live between 0-20 Myr with a high infant mortality (t' < 3 Myr) due to cloud mergers and star formation. Other properties, including distributions of mass, size and surface density agree well with observations. Collisions between our clouds are common, occurring at a rate of ~1/4 of the orbital period. It is not clear whether such collisions trigger or suppress star formation at our current resolution. Our star formation rate is a factor of 10 higher than observations in local galaxies. This is likely due to the absence of localized feedback in our models.
