Fields, Meadows, and Gardens – an Integral Part of the City
Creators: name: Ahrland, Åsa
Publisher: name: Rural History Yearbook
Year: 2019

description: As an increasing number of people live in towns and cities all over the world, the development of urban areas attracts attention. Urban planning in relation to quality of life and a sustainable society is on the political agenda and in the public eye. When it comes to food, modern towns and cities are today defined by consumers rather than producers. The urban agriculture movement is therefore often perceived as a new way to meet the needs of city life. However, throughout history towns and cities have had a high degree of self-sufficiency. It is often assumed that nineteenth- century rectilinear town planning was the main factor in bringing urban agriculture to an end. This study shows that in Södermalm, a central part of Stockholm which for a long time was characterised by a mix of industrial production, trade, craft, and cultivation, the fields did not disappear until after World War II. The view that agriculture was no longer compatible with modern city life and the concept of a green city constituted by parks and other green spaces as part of urban planning were connected to the interpretation of modernity in the Swedish welfare state, with its emphasis on rationality and efficiency, which lead to a dichotomy between urbanity and rurality.

description: We present a simple time dependent model for the excitation of a nucleon from a bound state to a continuum resonant state in a neutron-core complex potential which acts as a final state interaction. The final state is described by an optical model S-matrix so that both resonant and non resonant states of any continuum energy can be studied as well as deeply bound initial states. It is shown that, due to the coupling between the initial and final states, the neutron-core free particle phase shifts are modified, in the exit channel, by an additional phase. The effect of the additional phase on the breakup spectra is clarified. As an example the population of the low energy resonances of $^{11}$Be and of the unbound $^{13}$Be is discussed. Finally, we suggest that the excitation energy spectra of an unbound nucleus might reflect the structure of the parent nucleus from whose fragmentation they are obtained.

Urban Viticulture in Late Medieval and Early Modern Central Europe
Creators: name: Landsteiner, Erich
Publisher: name: Rural History Yearbook
Year: 2019

description: Vine-growing and wine production were to a large extent part of urban economy in late medieval and early modern Europe. This paper takes issue with the concept of Ackerbürgerstadt discussed in German urban history since the beginning of the twentieth century, to come to terms with the intense involvement of towns in agrarian production. By drawing on examples from the city of Vienna and the town of Retz in Lower Austria, it is argued that towns specialized in vine-growing, produced a cash-crop for regional and supra-regional markets, were troubled by class conflicts between vineyard owners and wage labourers, regulated labour relations extensively, and strove to dominate the local wine trade. This does not conform to the concept of Ackerbürgerstadt, implying food-crop production for subsistence and a low level of social stratification.

Optical storage technology : applications and implications for archives
Creators: name: Kovacs, Judith Susanna
Publisher: name: University of British Columbia
Year: 2009

description: Optical storage technology has advanced to the point where one can store megabytes and terabytes in a very small physical space. The use ofthis form of mass electronic storage has the potential to affect the way archives conserve, preserve, store and make accessible the records in their custody. Thus, it is important for archivists to understand not only the technology, but the implications of its use on traditional archival methods and practices. This study provides a description of the technology, conservation and preservation issues, and archival implications involved in the use of three optical storage systems: WORMs, Rewritables, and Optical Tape. Some of the technological, legal and archival problems associated with the use of these sytems by archival programs or institutions are discussed, and a few case studies involving the use of optical storage systems in archives are presented. This thesis concludes that, while there are problems associated with the use of optical storage systems as archival conservation and preservation tools, the advantages presented by these systems outweigh their disadvantages.
Focusing of branes in warped backgrounds

description: Branes are embedded surfaces in a given background (bulk) spacetime. Assuming a warped bulk, we investigate, in analogy with the case for geodesics, the notion of {\em focusing} of families of such embedded, extremal 3--branes in a five dimensional background . The essential tool behind our analysis, is the well-known generalised Raychaudhuri equations for surface congruences. In particular, we find explicit solutions of these equations, which seem to show that families of 3--branes can focus along lower dimensional submanifolds depending on where the initial expansions are specified. We conclude with comments on the results obtained and possibilities about future work along similar lines.

description: Although quantum channels underlie the dynamics of quantum states, maps which are not physical channels -- that is, not completely positive -- can often be encountered in settings such as entanglement detection, non-Markovian quantum dynamics, or error mitigation. We introduce an operational approach to the quantitative study of the non-physicality of linear maps based on different ways to approximate a given linear map with quantum channels. Our first measure directly quantifies the cost of simulating a given map using physically implementable quantum channels, shifting the difficulty in simulating unphysical dynamics onto the task of simulating linear combinations of quantum states. Our second measure benchmarks the quantitative advantages that a non-completely-positive map can provide in discrimination-based quantum games. Notably, we show that for any trace-preserving map, the quantities both reduce to a fundamental distance measure: the diamond norm, thus endowing this norm with new operational meanings in the characterisation of linear maps. We discuss applications of our results to structural physical approximations of positive maps, quantification of non-Markovianity, and bounding the cost of error mitigation.

description: We use computer simulations to obtain the directional-dependence of the lunar Cherenkov technique for ultra-high energy (UHE) neutrino detection. We calculate the instantaneous effective area of past lunar Cherenkov experiments as a function of neutrino arrival direction, and hence the directional-dependence of the combined limit imposed by GLUE and the experiment at Parkes. We also determine the directional dependence of the aperture of future planned experiments with ATCA, ASKAP and the SKA to a UHE neutrino flux, and calculate the potential annual exposure to astronomical objects as a function of angular distance from the lunar trajectory through celestial coordinates.

description: Antiproton proton annihilation reactions allow unique access to the moduli and phases of nucleon electromagnetic form factors in the time like region. We present the helicity amplitudes for the unequal mass single photon reaction $p \bar{p}\to l^+ l^-$ in the s channel including the lepton mass. The relative signs of these amplitudes are determined using simple invariance properties. Helicity amplitudes for the annihilation reaction $p \bar{p} \to N \bar{N}$ are also given, where $N$ is any spinor particle with structure. Crossing relations between the $e p \to e p$ scattering and the $p \bar{p}\to l^+ l^-$ annihilation channels are discussed and the crossing matrix for the helicity amplitudes is given. This matrix may be used to verify known expressions for the space like helicity amplitudes due to one photon exchange.

Reconciling Tradition and Innovation in Traditional Mountain Cheese Value Chains: The Role of Social Capital
Creators: name: Pachoud, Carine
name: Schermer, Markus
Publisher: name: Rural History Yearbook
Year: 2019

description: Globalised and production-oriented agriculture often leads to the exclusion of rural mountain areas and to the marginalisation of their traditional food value chains, of which cheese is particularly interesting. Important elements for such value chains are the valorisation of the product quality and of traditional know-how. Territorial innovations, defined as a response to a problem identified collectively in a territory, allow adaptation to changes. Reconciling tradition with territorial innovation is central for the resilience of the value chain and social capital is the resource that needs to be mobilised to cooperate and innovate. In this contribution, we analyse the history of the artisanal Serrano cheese in southern Brazil. The aim of this article is to analyse strategies for building a resilient artisanal Serrano cheese value chain by studying the role of social capital in the balance between maintaining traditions and the emergence of territorial innovations. In the results, first, we observe that the peasant families are central actors in maintaining tradition by passing on know-how to the next generations through bonding social capital. Second, the agricultural advisory services (EMATER-RS and EPAGRI-SC) are the central actors in the innovation processes by diffusing technical innovations, but also for the emergence of organisational innovations through the creation of producers’ associations. The associations allow connecting the different actors of the value chain through linking and bridging social capital, necessary for territorial innovation to emerge.

description: Like other experimental techniques, X-ray Photon Correlation Spectroscopy is subject to various kinds of noise. Random and correlated fluctuations and heterogeneities can be present in a two-time correlation function and obscure the information about the intrinsic dynamics of a sample. Simultaneously addressing the disparate origins of noise in the experimental data is challenging. We propose a computational approach for improving the signal-to-noise ratio in two-time correlation functions that is based on Convolutional Neural Network Encoder-Decoder (CNN-ED) models. Such models extract features from an image via convolutional layers, project them to a low dimensional space and then reconstruct a clean image from this reduced representation via transposed convolutional layers. Not only are ED models a general tool for random noise removal, but their application to low signal-to-noise data can enhance the data quantitative usage since they are able to learn the functional form of the signal. We demonstrate that the CNN-ED models trained on real-world experimental data help to effectively extract equilibrium dynamics parameters from two-time correlation functions, containing statistical noise and dynamic heterogeneities. Strategies for optimizing the models performance and their applicability limits are discussed.

Bhā-viveka (A.D. c. 490-570)’s Madhyamaka-hṛdaya-kārikā, Tattvajñānaiṣanā, verses 137-266 : an English translation and explanation
Creators: name: Watanabe, Chikafumi
Publisher: name: University of British Columbia
Year: 2009

description: The aim of this thesis is an English translation and elucidation of the third chapter, Tattvajnt1naianã, (vv. 137-266 ) of Madhyamaka-hdaya-kãrikt (MHK)of Bhãviveka (A.D. c. 490-570). Bhaviveka was one of the commentators of Madhyamaka-kãrik of Nagarjuna, the founder of the Madhyamika, and, at the same time, was a significant philosopher. MHK is one of Bhãviveka’s most important works. In the MHK, Bhaviveka gives a his own philosophy in chapters 1-3, and thereafter, presents and criticizes Buddhist and non-Buddhist systems opposing Madhyamaka philosophy in chapters 4-9. The Sanskrit text of the third chapter was critically edited and translated into Japanese by Yasunori Ejima. Shotaro lida, also, published a critical Sanskrit edition of verses 1-136 of the same chapter and of the Tibetan text of Madhyamaka-hrdaya-tarkajvala (TJ), a commentary on MHK, corresponding to those verses, and produced an English translation. The main subject of verses 137-256 is “the non-production of all dharmas.” This is also the main subject of Madhyamaka philosophers beginning with Nagarjuna. Many of them tried to explain it by means of their own methods and to examine it from their own viewpoint. Non-production of all dharmas implies the emptiness (unyata) of all entities in our world. The idea of emptiness is, according to the Madhyamikas, basic and very important among the Buddha’s teachings. It can be said that without understanding this idea, no understanding of the philosophy of the Madhyamika is possible. Therefore, I have decided to translate and explain in this thesis Bha-viveka’s views on “non-production of entities.” Nagarjuna, Buddhapalita and Candrakirti used prasañga-anumana in order to clarify the philosophy of emptiness. That is to say, by pointing out the absurdity of the opponent’s opinion, they tried to demonstrate the philosophy of emptiness. In other words, they did not take firm stand on their claims in order to have consensus by other schools. Bhãviveka, on the other hand, was not satisfied with prasaHga-anumana, and tried to clarify the philosophy of emptiness by means of independent syllogism (svatantra-anumãna), including the three modifications: (1) adding of the word paramãrthataz (from the standpoint of the highest truth) to propositions in syllogisms, (2) specification that the negation in syllogisms should be understood as prasajya-pratiedha (the negation of a proposition or the simple negation of a proposition) and (3) the condition that no counter-example (vipaka) is to be given. In other words, he positively demonstrated the philosophy of emptiness by using independent syllogism.

description: We discuss the generation of field-induced entanglement between two objects each in a superposition of two trajectories.The objects have currents coupled to local quantum fields, and the currents are evaluated around each trajectory of the objects.The fields have only dynamical degrees of freedom and satisfy the microcausality condition. We find that the superposed state of trajectories cannot be entangled when the objects are spacelike separated.This means that the quantum fields do not generate spacelike entanglement in the superposition of two trajectories of each object.

This generalized master equation allows us to obtain multiple integral representations for the correlation functions of these models. We apply this method to derive the density-density correlation functions of the quantum non-linear Schrodinger model.

Equivariant homotopy theory for pro-spectra

description: We extend the theory of equivariant orthogonal spectra from finite groups to profinite groups, and more generally from compact Lie groups to compact Hausdorff groups. The G-homotopy theory is "pieced together" from the G/U-homotopy theories for suitable quotient groups G/U of G; a motivation is the way continuous group cohomology of a profinite group is built out of the cohomology of its finite quotient groups. In the model category of equivariant spectra Postnikov towers are studied from a general perspective. We introduce pro-G-spectra and construct various model structures on them. A key property of the model structures is that pro-spectra are weakly equivalent to their Postnikov towers. We discuss two versions of a model structure with "underlying weak equivalences". One of the versions only makes sense for pro-spectra. In the end we use the theory to study homotopy fixed points of pro-G-spectra.

description: A single-spin qubit placed near the surface of a conductor acquires an additional contribution to its $1/T_1$ relaxation rate due to magnetic noise created by electric current fluctuations in the material. We analyze this technique as a wireless probe of superconductivity in atomically thin two dimensional materials. At temperatures $T \lesssim T_c$, the dominant contribution to the qubit relaxation rate is due to transverse electric current fluctuations arising from quasiparticle excitations. We demonstrate that this method enables detection of metal-to-superconductor transitions, as well as investigation of the symmetry of the superconducting gap function, through the noise scaling with temperature. We show that scaling of the noise with sample-probe distance provides a window into the non-local quasi-static conductivity of superconductors, both clean and disordered. At low temperatures the quasiparticle fluctuations get suppressed, yet the noise can be substantial due to resonant contributions from collective longitudinal modes, such as plasmons in monolayers and Josephson plasmons in bilayers. Potential experimental implications are discussed.

description: This article explores the role of the cinema in the society of rural Lithuania during the Stalinist era. The core of this article is an empirical analysis of cinema practices such as exhibition places and distribution. During the Soviet period these practices were referred to as the process of Cinefication (kinofikatsia). Cinefication not only was an integral element of the Soviet industrialisation but was part of a propaganda strategy. It demonstrated the technological power of the Soviet Union and used cinematic tools for an ideological indoctrination. Key research questions of this article are: What were the most essential features of the Cinefication? Did the process acquire distinctive aspects? Were the advantages of cinema utilised in the invaded area? The situation in Lithuania testifies to cultural politics and cinema politics in the rural periphery of the Soviet Union where inhabitants experienced film for the first time.

description: In this paper we present a discussion of a phenomenological model of the MAPK cascade which was originally proposed by Angeli et al. (PNAS 101, 1822 (2004)). The model and its solution are extended in several respects: a) an analytical solution is given for the cascade equilibria, exploiting a parameter-based symmetry of the rate equations; b) we discuss the cooperativity (Hill coefficients) of the cascade and show that a feedforward loop within the cascade increases its cooperativity. The relevance of this result for the notion of modularity is discussed; c) the feedback model for cascade bistability by Angeli et al. is reconsidered. We argue that care must be taken in modeling the interactions and a biologically realistic phenomenological model cannot be too reductionist. The inclusion of a time-dependent degradation rate is needed to account for a switching of the cascade.

description: We propose nanoscale magnetometry via isolated single-spin qubits as a probe of superconductivity in two-dimensional materials. We characterize the magnetic field noise at the qubit location, arising from current and spin fluctuations in the sample and leading to measurable polarization decay of the qubit. We show that the noise due to transverse current fluctuations studied as a function of temperature and sample-probe distance can be used to extract useful information about the transition to a superconducting phase and the pairing symmetry of the superconductor. Surprisingly, at low temperatures, the dominant contribution to the magnetic noise arises from longitudinal current fluctuations and can be used to probe collective modes such as monolayer plasmons and bilayer Josephson plasmons. We also characterize the noise due to spin fluctuations, which allows probing the spin structure of the pairing wave function. Our results provide a non-invasive route to probe the rich physics of two-dimensional superconductors.

description: A quantitative spectral analysis of 24 A supergiants in the Sculptor Group spiral galaxy NGC 300 at a distance of 1.9 Mpc is presented. A new method is introduced to analyze low resolution (~5 AE) spectra, which yields metallicities accurate to 0.2 dex including the uncertainties arising from the errors in Teff (5%) and log g (0.2 dex). For the first time the stellar metallicity gradient based on elements such as titanium and iron in a galaxy beyond the Local Group is investigated. Solar metallicity is measured in the center and 0.3 solar in the outskirts and a logarithmic gradient of -0.08 dex/kpc. An average reddening of E(B-V)~0.12 mag is obtained, however with a large variation from 0.07 to 0.24 mag. We also determine stellar radii, luminosities and masses and discuss the evolutionary status. Finally, the observed relationship between absolute bolometric magnitudes M_{bol} and flux weighted gravities g_{F} = g/Teff^4 is investigated. At high temperatures the strengths of the Balmer lines depends solely on the flux-weighted gravity, which allows a precise direct determination of log g_{F} with an accuracy of 0.05 to 0.1 dex. We find a tight relationship between M_{bol} and log g_{F} in agreement with stellar evolution theory. Combining these new results with previous work on Local Group galaxies we obtain a new flux weighted gravity luminosity relationship (FGLR), which is very well defined and appears to be an excellent alternative tool to determine distances to galaxies.

description: Fetal hypoxia is a non–specific manifestation of various complications of pregnancy and childbirth, primarily toxicosis of pregnant women. The degree and severity of toxicosis, its connection with the extragenital pathology of a woman (especially with diseases of the cardiovascular system) determine the duration and severity of fetal hypoxia, whose central nervous system is most sensitive to oxygen deficiency.

description: Continuous-variable (CV) cluster states are a universal resource for fault-tolerant quantum computation when supplemented with the Gottesman-Kitaev-Preskill (GKP) bosonic code. We generalize the recently introduced subsystem decomposition of a bosonic code [Phys. Rev. Lett. 125, 040501 (2020)], and we use it to analyze CV cluster-state quantum computing with GKP states. Specifically, we decompose squeezed vacuum states and approximate GKP states to reveal their encoded logical information, and we decompose several gates crucial to CV cluster-state quantum computing. Then, we use the subsystem decomposition to quantify damage to the logical information in approximate GKP states teleported through noisy CV cluster states. Each of these studies uses the subsystem decomposition to circumvent complications arising from the full CV nature of the mode in order to focus on the encoded qubit information.

description: We investigate charge relaxation rates due to acoustic phonons in weakly-confined quantum dot systems, including both deformation potential and piezoelectric field interactions. Single-electron excited states lifetimes are calculated for single and coupled quantum dot structures, both in homonuclear and heteronuclear devices. Piezoelectric field scattering is shown to be the dominant relaxation mechanism in many experimentally relevant situations. On the other hand, we show that appropriate structure design allows to minimize separately deformation potential and piezolectric field interactions, and may bring electron lifetimes in the range of microseconds.

description: We investigate quantum-statistical correlation properties of a periodically driven mesoscopic scatterer on a time-scale shorter than the period of a drive. In this limit the intrinsic quantum fluctuations in the system of fermions are the main source of a noise. Nevertheless the effect of a slow periodic drive is clearly visible in a two-time current-current correlation function as a specific periodic in time modulation. In the limit of a strong drive such a modulation can change the sign of a current correlation function.

Presenting the Prince : the Medici Chapel at San Lorenzo and sixteenth-century theatre
Creators: name: Wilson, Bronwen
Publisher: name: University of British Columbia

description: The devotion to theatre during the ducal reign of Cosimo and his successors has garnered an extensive literature. This theatre orientation was prepared for in the first stages of the Medici return, and was a deeply ingrained part of their political imaging. The revival of antique theatre, the emergence of scenography, and the spatial dynamics of theatrical representations became instruments of political persuasion. Theatrical devices and the development of prospettive presented the illusion of continuity beyond the space of the representation, linking the space of the audience with the space of the performer, creating a reciprocal involvement. Spectacles co-opted the viewer, providing the means to physically structure the relationship between the audience and the performance. The viewer could be both a spectator and a performer, sometimes at the same time: both a witness to, and a conspirator in, the production of meaning. The Medici program of legitimization through display was designed to counter the eradication of Medici signs during the republican years and to bolster their fragile position following their return to Florence in 1512. Theatrical spectacle, fueled by Giovanni de’Medici’s election to the papacy, became the vehicle through which Medicean cultural and poltical hegemony was propagated. Through theatrical illusion the family laid claim to the city. The Diamante and Broncone festivals and Leo’s Florentine entrata of 1515 provided events in which the Medici dramatized their claims to Florence. The 1513 Capitoune celebration in Rome was a singular event, discussed at length here in terms of its Florentine references and its connection to the chapel. These spectacles were exceptions to the recurring festivals, thus signifying with greater specificity, their political function magnified. Rapid transformations, fabric Iaçades, wooden arches, paper friezes, and human sculptures provided the illusion that through Medici rule Florence was restored to good health. Through tableaux vivants and rappresentazioni, the Medici transformed republican space into court space, gradually shifting theatre from the public domain into the private dominion of the ‘prince’. At the death of Lorenzo in 1519, the last Medici heir, a family mausoleum was commissioned by Leo X and Cardinal Giullo de’Fvledici. The enclosed Medici Chapel -- its entrance protected from the outside world by effigies of the captains Lorenzo and Giuliano -- positions the visitor as the subject of the space. Surveyed by the captains and an object of scrutiny by the ubiquitous masks, the spectator is simultaneously on stage arid a member of the audience, a double role that permeates contemporary discourses where masks, performance, and disguise are central themes. The argument of this thesis is that the Medici chapel is a permanent theatrical presentation, in advance of the full Medici restoration.

description: The latest measurement of the muon anomalous magnetic moment $a^{}_μ \equiv (g^{}_μ- 2)/2$ at the Fermi Laboratory has found a $4.2\,σ$ discrepancy with the theoretical prediction of the Standard Model (SM). Motivated by this exciting progress, we investigate in the present paper the general one-loop contributions to $a^{}_μ$ within the SM and beyond. First, different from previous works, the analytical formulae of relevant loop functions after integration are now derived and put into compact forms with the help of the Passarino-Veltman functions. Second, given the interactions of muon with new particles running in the loop, we clarify when the one-loop contribution to $a^{}_μ$ could take the correct positive sign as desired. Third, possible divergences in the zero- and infinite-mass limits are examined, and the absence of any divergences in the calculations leads to some consistency conditions for the construction of ultraviolet complete models. Applications of our general formulae to specific models, such as the SM, seesaw models, $Z^\prime$ and leptoquark models, are also discussed.

description: We study the spin dynamics of quasi-one-dimensional F=1 condensates both at zero and finite temperatures for arbitrary initial spin configurations. The rich dynamical evolution exhibited by these non-linear systems is explained by surprisingly simple principles: minimization of energy at zero temperature, and maximization of entropy at high temperature. Our analytical results for the homogeneous case are corroborated by numerical simulations for confined condensates in a wide variety of initial conditions. These predictions compare qualitatively well with recent experimental observations and can, therefore, serve as a guidance for on-going experiments.

description: Nonlinear Compton scattering is an inelastic scattering process where a photon is emitted due to the interaction between an electron and an intense laser field. With the development of X-ray free-electron lasers, the intensity of X-ray laser is greatly enhanced, and the signal from X-ray nonlinear Compton scattering is no longer weak. Although the nonlinear Compton scattering by an initially free electron has been thoroughly investigated, the mechanis of nonrelativistic nonlinear Compton scattering of X-ray photons by bound electrons is unclear yet. Here, we present a frequency-domain formulation based on the nonperturbative quantum electrodynamic to study nonlinear Compton scattering of two photons off a bound electron inside an atom in a strong X-ray laser field. In contrast to previous theoretical works, our results clearly reveal the existence of anomalous redshift phenomenon observed experimentally by Fuchs et al. (Nat. Phys. 11, 964 (2015)) and suggest its origin as the binding energy of the electron as well as the momentum transfer from incident photons to the electron during the scattering process. Our work builds a bridge between intense-laser atomic physics and Compton scattering process that can be used to study atomic structure and dynamics at high laser intensities.
