Pancreatic beta cells

description: Human and murine diabetes is characterized by pancreatic β-cell dedifferentiation, a process in which β-cells lose expression of markers of maturity and gain those of endocrine progenitors. Failing β-cells inappropriately metabolize lipids over carbohydrates and exhibit impaired mitochondrial oxidative phosphorylation. Therefore, pathways involved in mitochondrial fuel selection and catabolism may represent potential targets for the prevention or reversal of dedifferentiation.
      In chapter I of this dissertation, we isolated and functionally characterized failing β-cells from various experimental models of diabetes. We found a striking enrichment in the expression of aldehyde dehydrogenase 1 isoform A3 (Aldh1a3) as β-cells become dedifferentiated. Flow-sorted Aldh1a3-expressing (ALDH+) islet cells demonstrate impaired glucose-induced insulin secretion, are depleted of Foxo1 and MafA, and include a Neurogenin3-positive subset. RNA sequencing analysis demonstrated that ALDH+ cells are characterized by: (i) impaired oxidative phosphorylation and mitochondrial complex I, IV, and V; (ii) activated RICTOR; and (iii) progenitor cell markers. We propose that impaired mitochondrial function marks the progression from metabolic inflexibility to dedifferentiation in the natural history of β-cell failure.
      In chapter II of this dissertation, we report that cytochrome b5 reductase 3 (Cyb5r3) is a FoxO1-regulated mitochondrial oxidoreductase critical to β cell function. Expression of Cyb5r3 is greatly decreased in multiple murine models of diabetes, and in vitro Cyb5r3 knockdown leads to increased ROS generation and impairment of respiration, mitochondrial function, glucose-stimulated insulin secretion, and calcium mobilization. In vivo, mice with β-cell-specific ablation of Cyb5r3 (B-Cyb5r3) display impaired glucose tolerance with decreased insulin secretion, and their islets have significantly lower basal respiration and glucose-stimulated insulin secretion. B-Cyb5r3 β-cells lose expression of Glut2, MafA, and Pdx1 expression despite a compensatory increase in FoxO1 expression. Our data suggest that Cyb5r3 is a critical mediator of FoxO1’s protective response in β-cells, and that loss of Cyb5r3 expression is an early event in β-cell failure.

Rural tourism

description: With the rapid growth of urbanization, more and more people seek short reliefs in rural area during free time. Rural tourism is developing with the increasing need and requirement of urban residents. This study selects SanSheng Hua Villages as a case study to analyze the supply, demand, and strategies of the rural tourism market. This thesis utilizes Analytic hierarchy process-Fuzzy synthetic evaluation model and SWOT (Strengths, Weaknesses, Opportunities, and Threats) model to explore the present situation and tourists' attitudes toward SanSheng Hua Xiang. The result shows that the rural tourism market has the problems of homogenization, deficient infrastructure, messy and unprofessional management. The author thus recommends increasing characteristics, creativity, and unified management in SanSheng Hua Village for the future.

description: The massive nonsymmetric gravitational theory is shown to posses a linearisation instability at purely GR field configurations, disallowing the use of the linear approximation in these situations. It is also shown that arbitrarily small antisymmetric sector Cauchy data leads to singular evolution unless an ad hoc condition is imposed on the initial data hypersurface.

description: Wind farms are an indispensable driver toward renewable and nonpolluting energy resources. However, as ideal sites are limited, placement in remote and challenging locations results in higher logistics costs and lower average wind speeds. Therefore, it is critical to increase the reliability of the turbines to reduce maintenance costs. Robust implementation requires a thorough understanding of the loads subject to the turbine's control. Yet, such dynamically changing multidimensional loads are uncommon with other machinery, and generally underresearched. Therefore, a multitiered approach is proposed to investigate the load spectrum occurring in wind farms. Our approach relies on both fundamental research using controllable test rigs, as well as analyses of real-world loading conditions in high-frequency supervisory control and data acquisition data. A method is introduced to detect operational zones in wind farm data and link them with load distributions. Additionally, while focused research further investigates the load spectrum, a method is proposed that continuously optimizes the farm's control protocols without the need to fully understand the loads that occur. A case of gearbox failure is investigated based on a vast body of past experiments and suspect loads are identified. Starting from this evidence on the cause and effects of dynamic loads, the potential of our methods is shown by analyzing real-world farm loading conditions on a steady-state case of wake and developing a preventive row-based control protocol for a case of cascading emergency brakes induced by a storm.

description: In 1974 a sewer trench, some 16ft. (5m.) deep, crossed The Street, Bramber, 105ft. (32m.) east of the fifteenth century timbered house known as St. Mary's, striking the foundation of one of the piers of Bramber's medieval stone bridge. Timber piles, some 9� to 11ft. (2.9-3.4m.) below the surface, were encountered both north and south of the pier (Figs. 1 and 2). Recording was difficult owing to the dangerous nature of the subsoil, which required sheet piling, thus exposures of trench faces were rarely seen. The writer recorded the bridge pier and those wooden piles drawn in solid black (Fig. 2), whereas the piles shown in dotted outline were discovered when he was not at the site. However, the watchfulness of the Site Engineer, Clerk of Works, or Agent, enabled the information to be passed on.

As D. grandiflora Rudge is an illegitimate name, E. jenmanii Oliv., which is its heterotypic synonym, is the correct name for the taxon.

History

description: This dissertation examines the connections between global capitalism, modern medicine, and empire through a close study of Hoshi Pharmaceuticals during the interwar years. As one of the leading drug companies in East Asia at the time, Hoshi embodied Japan's imperial aspirations, rapid industrial development, and burgeoning consumer culture. The company attempted to control every part of its supply and distribution chain: it managed plantations in the mountains of Taiwan and Peru for growing coca and cinchona (the raw material for quinine) and contracted Turkish poppy farmers to supply raw opium for government-owned refineries in Taiwan. Hoshi also helped shape modern consumer culture in Japan and its colonies, and indeed, became an emblem for it. At its peak in the early 1920s, Hoshi had a network of chain stores across Asia that sold Hoshi-brand patent medicines, hygiene products, and household goods. In 1925, however, the company's fortunes turned for the worse when an opium trading violation raised suspicions of Hoshi as a front for the smuggling of narcotics through Manchuria and China. Although the company was a key supplier of medicines to Japan's military during World War Two, it could not financially recover from the fallout of the opium scandal. In 1952, the industrialist Otani Yonetaro seized control of the company from the Hoshi family. By tracing Hoshi's activities across Japan's expanding empire and beyond, this dissertation shows how private, transnational drug companies such as Hoshi played a vital role in manufacturing and selling Japan as a modern nation and empire. Like many other transnational corporations during the autarkic global climate of the interwar years, Hoshi constantly looked abroad to learn about, borrow, and translate technologies that were circulating across the globe to support the "business" of empire building. Hoshi Pharmaceuticals embodied the symbiotic connections between government and business interests; an ideology of cooperation where the "interests of capital and labor are one"; and adaptations of global, particularly American, technologies of management.
The Lowest Landau Level Anyon Equation of State in the Anti-screening Regime

description: The thermodynamics of the anyon model projected on the lowest Landau level (LLL) of an external magnetic field is addressed in the anti-screening regime, where the flux tubes carried by the anyons are parallel to the magnetic field. It is claimed that the LLL-anyon equation of state, which is known in the screening regime, can be analytically continued in the statistical parameter across the Fermi point to the antiscreening regime up to the vicinity (whose width tends to zero when the magnetic field becomes infinite) of the Bose point. There, an unphysical discontinuity arises due to the dropping of the non-LLL eigenstates which join the LLL, making the LLL approximation no longer valid. However, taking into account the effect of the non-LLL states at the Bose point would only smoothen the discontinuity and not alter the physics which is captured by the LLL projection: Close to the Bose point, the critical filling factor either goes to infinity (usual bosons) in the screening situation, or to 1/2 in the anti-screening situation, the difference between the flux tubes orientation being relevant even when they carry an infinitesimal fraction of the flux quantum. An exclusion statistics interpretation is adduced, which explains this situation in semiclassical terms. It is further shown how the exact solutions of the 3-anyon problem support this scenario as far as the third cluster coefficient is concerned.

Using Klich's theory of full counting statistics for paired fermions we generalize the Pfaffian formula to account for quantum fluctuations in the fermion parity of an open subsystem. A statistical description in the framework of random-matrix theory is used to answer the question when a vanishing fermion parity in a superconductor fusion experiment becomes a distinctive signature of an isolated Majorana zero-mode.

Market reform, medical care, and public service: Dilemmas of municipal primary care provision in urban India

description: Studies across low- and middle-income countries document quality shortfalls in both public and private sector health care. They notably highlight a “know-do” gap in primary care delivery: doctors possess requisite medical knowledge but do not expend adequate effort to treat patients. In explaining low quality, researchers have largely emphasized transactional aspects of health care, viewing doctors’ actions as shaped by their skills and incentives to perform and arguing that the micro-institutions that drive doctors’ clinical behavior are faulty.
      In contrast, in this project I analyze the social and political conditions in which public sector doctors deliver primary care in urban India. Viewing the doctors as both medical practitioners and state agents, I argue that health service outcomes depend on how doctors interpret policy mandates and relate to the communities they serve. I conceptualize their actions not just as medical transactions but also as social acts, shaped by the meanings they attach to their experiences and informed by the institutional history and social imaginary of state-provided care.
      During a year of ethnographic fieldwork (2013-2014), I observed clinical and non-clinical encounters of doctors employed in municipal government clinics and hospitals in a midsize Indian city; interviewed doctors, other health workers, elected officials, administrators, and staff of non-governmental organizations; and examined policies and administrative arrangements for urban health care since India’s independence.
      I demonstrate that municipal doctors confront a trifecta of challenges: a legal obligation to deliver urban primary care from within an outdated urban governance structure; a largely unregulated private sector that residents widely prefer; and rising commercialization in medical practice, under which specialized medicine has crowded out primary care in popular ideas about “good” medical care. Unable to remedy the low legitimacy of their services, doctors circumscribe their actions, seeking, as one doctor put it, only to ensure the ordinary. My findings suggest that transaction-specific interventions to improve quality, such as focused on skills and incentives alone, may do little to circumvent these local effects of the policy neglect of urban health care.

description: We argue that the statistical entropy relevant for the thermal interactions of a black hole with its surroundings is (the logarithm of) the number of quantum microstates of the hole which are distinguishable from the hole's exterior, and which correspond to a given hole's macroscopic configuration. We compute this number explicitly from first principles, for a Schwarzschild black hole, using nonperturbative quantum gravity in the loop representation. We obtain a black hole entropy proportional to the area, as in the Bekenstein-Hawking formula.

description: This thesis deals, as its subtitle indicates, with tourism on the neighborhood level. In it, I provide a comparative account of the recent history of tourism development in Berlin-Kreuzberg and Harlem, New York. Grounded in a discussion of the forces reconfiguring urban development as well as tourism in the advanced capitalist world, it examines how, by whom, and with what effects the two neighborhoods are re-imagined, re-constructed, and re-experienced as places to visit and explore; unburies the frequently omitted historicity of "slumming" and other niche tourism practices impacting so-called marginalized neighborhoods; elaborates upon the potential of tourism for socially equitable forms of neighborhood development and explores how the old face of tourism is being challenged by the increasingly complex and diverse realities of contemporary travel and leisure. Understanding tourism as a complex, dynamic system rather than simply an industry or process, the thesis pays particular emphasis to the need to rethink the way the demand side of tourism in cities is conceived and made sense of. Whereas tourism consumption in urban research has traditionally been framed as an altogether distinct activity, my research posits that distinctions between tourism and other forms of migration on the one hand as well as tourism and other forms of leisure and place consumption on the other hand have become increasingly blurred. This, I argue, not only brings about significant changes with regard to cities' tourism and leisure landscapes. Rather, I also find evidence that the increasing pervasiveness of mobility and tourism as well as its increased dedifferentiation, i.e. the blurred boundaries between tourism and non-tourism activities, also transforms meanings of place and space and raises important questions concerning several critical concepts in urban studies such as the notions of 'citizenship', 'community', and 'belonging' in the 21st century.

description: Search for methods of deriving actionable marketing segmentation has a long history in the marketing literature. This work proposes the use of Markov clustering algorithm on person-to-person similarity graph, where similarity between individuals is based on their similarity in rating assignments. This allows the detection of taste-based communities of users. Simple regression analysis is subsequently applied to detect the dependencies of box office results of movies of various genres on the preferences of specific viewer communities. The resulting analysis permitted identification of communities that drive box office results of specific movie genres.

description: This dissertation is a comparative and transnational study of the techniques of racial impersonation used by white performers to represent black Afro-diasporic people in early modern England, Spain, and France. The racialization of blackness that took place in England at the turn of the sixteenth century has been well studied over the course of the last thirty years. This dissertation expands English early modern race scholarship in new directions by revealing the existence of a multi-directional circulation of racial ideas, lexemes, and performance techniques that led to the development of a vivid trans-European stage idiom of blackness across national borders in the sixteenth and seventeenth centuries. While early modern race scholarship has traditionally focused on the rhetorical and dramatic strategies used by playwrights to create black characters, this dissertation brings to the fore the ideological work inherent in performance. It does so by arguing that the techniques of racial impersonation used in various loci of European performance culture, such as blackface, blackspeak (a comic mock-African accent), and black dances, racialized Afro-diasporic people as they led spectators in a variety of ways to think of those people as belonging naturally at the bottom of any well-constituted social order. This dissertation shows how the hermeneutic configurations and re-configurations of techniques of racial impersonation such as blackface, blackspeak, and black dance responded to social changes, to the development of colonization and color-based slavery, and to changing perceptions of what Afro-diasporic people’s status should be in European and Atlantic societies across the early modern period.

description: In recent years a unified phenomenological picture for the hole doped high-T_c cuprates has emerged for a spin and charge spectroscopy. Spectral anomalies have been interpreted as evidence of charge carrier coupling to a collective spin excitation present in the optical conductivity, in ARPES (angular resolved photoemission), and in tunneling data. These anomalies can be used to derive an approximate picture of a charge carrier-exchange boson interaction spectral density I^2 chi(omega) which is then be used within an extended Eliashberg formalism to analyze normal and superconducting properties of optimally doped and overdoped cuprates. This paper reviews recent developments and demonstrates the sometimes astonishing agreement between experiment and theoretical prediction.

description: We study quantum gravitational effects on black hole radiation, using loop quantum gravity. Bekenstein and Mukhanov have recently considered the modifications caused by quantum gravity on Hawking's thermal black-hole radiation. Using a simple ansatz for the eigenstates the area, they have obtained the intriguing result that the quantum properties of geometry affect the radiation considerably, yielding a definitely non-thermal spectrum. Here, we replace the simple ansatz employed by Bekenstein and Mukhanov with the actual eigenstates of the area, computed using the loop representation of quantum gravity. We derive the emission spectra, using a classic result in number theory by Hardy and Ramanujan. Disappointingly, we do not recover the Bekenstein-Mukhanov spectrum, but --effectively-- a Hawking's thermal spectrum. The Bekenstein-Mukhanov result is therefore likely to be an artefact of the naive ansatz, rather than a robust result. The result is an example of concrete (although somewhat disappointing) application of nonperturbative quantum gravity.

description: Charge and energy transfer in biological and synthetic organic materials are strongly influenced by the coupling of electronic states to high-frequency underdamped vibrations under dephasing noise. Non-perturbative simulations of these systems require a substantial computational effort and current methods can only be applied to large systems with severely coarse-grained environmental structures. In this letter, we introduce a dissipation-assisted matrix product factorization (DAMPF) method based on a memory-efficient matrix product operator (MPO) representation of the vibronic state at finite temperature. In this approach, the correlations between environmental vibrational modes can be controlled by the MPO bond dimension, allowing for systematic interpolation between approximate and numerically exact dynamics. Crucially, by subjecting the vibrational modes to damping, we show that one can significantly reduce the bond dimension required to achieve a desired accuracy, and also consider a continuous, highly structured spectral density in a non-perturbative manner. We demonstrate that our method can simulate large vibronic systems consisting of 10-50 sites coupled with 100-1000 underdamped modes in total and for a wide range of parameter regimes. An analytical error bound is provided which allows one to monitor the accuracy of the numerical results. This formalism will facilitate the investigation of spatially extended systems with applications to quantum biology, organic photovoltaics and quantum thermodynamics.
Bluebell Mine : foreshore remediation of Galena Bay

description: In 1997, Cominco Ltd. initiated an environmental assessment and remedial program at its Bluebell Mine site which closed in 1972. An overview of the history of the mine and the complete project is provided in the companion paper titled Bluebell Mine - Remediation of a Historic Mine Site. This paper focuses on the management of tailing, concentrates (process fines) and mine water discharge (MWD) fines present on the foreshore of Galena Bay associated with the former concentrator operation. It explores the rationale and planning of the remedial work, and the challenges associated with completing the project. The results of environmental assessments of the site determined that groundwater crossing the foreshore areas of Galena Bay was being impacted by process fines and MWD fines. The remedial plan called for the removal of these materials and subsequent reconstruction of a "self-cleaning" beach. When planning the remedial action, many factors were considered, including: sediment chemistry; physical properties of the sediment; ecological health of Galena Bay; hydrodynamics of the bay; alternative excavation methods; containment of suspended sediments generated by the remedial work; and monitoring the effectiveness of the environmental control systems during excavation. Protection of the aquatic environment was the most critical aspect of the remedial work. Containment of suspended sediments within the work area was achieved by the use of a dual floating silt barrier system. The systematic monitoring of water quality using field and laboratory methods was undertaken to track the performance of the control system. The sediment control system worked well but its performance could have been enhanced by moving the primary barrier further from the work area, improving the design of certain barrier components and having earlier routine underwater inspections.

description: In semiclassical theories for chaotic systems such as Gutzwiller's periodic orbit theory the energy eigenvalues and resonances are obtained as poles of a non-convergent series g(w)=sum_n A_n exp(i s_n w). We present a general method for the analytic continuation of such a non-convergent series by harmonic inversion of the "time" signal, which is the Fourier transform of g(w). We demonstrate the general applicability and accuracy of the method on two different systems with completely different properties: the Riemann zeta function and the three disk scattering system. The Riemann zeta function serves as a mathematical model for a bound system. We demonstrate that the method of harmonic inversion by filter-diagonalization yields several thousand zeros of the zeta function to about 12 digit precision as eigenvalues of small matrices. However, the method is not restricted to bound and ergodic systems, and does not require the knowledge of the mean staircase function, i.e., the Weyl term in dynamical systems, which is a prerequisite in many semiclassical quantization conditions. It can therefore be applied to open systems as well. We demonstrate this on the three disk scattering system, as a physical example. The general applicability of the method is emphasized by the fact that one does not have to resort a symbolic dynamics, which is, in turn, the basic requirement for the application of cycle expansion techniques.

description: This paper addresses how two time integration schemes, the Heun's scheme for explicit time integration and the second-order Crank-Nicolson scheme for implicit time integration, can be coupled spatially. This coupling is the prerequisite to perform a coupled Large Eddy Simulation / Reynolds Averaged Navier-Stokes computation in an industrial context, using the implicit time procedure for the boundary layer (RANS) and the explicit time integration procedure in the LES region. The coupling procedure is designed in order to switch from explicit to implicit time integrations as fast as possible, while maintaining stability. After introducing the different schemes, the paper presents the initial coupling procedure adapted from a published reference and shows that it can amplify some numerical waves. An alternative procedure, studied in a coupled time/space framework, is shown to be stable and with spectral properties in agreement with the requirements of industrial applications. The coupling technique is validated with standard test cases, ranging from one-dimensional to three-dimensional flows.

description: We present our recent understanding on resolutions of Gorenstein orbifolds, which involves the finite group representation theory. We shall concern only the quotient singularity of hypersurface type. The abelian group $A_r(n)$ for $A$-type hypersurface quotient singularity of dimension $n$ is introduced. For $n=4$, the structure of Hilbert scheme of group orbits and crepant resolutions of $A_r(4)$-singularity are obtained. The flop procedure of 4-folds is explicitly constructed through the process.

Marriage and Hypogamy: The effects of Hyper/Hypogamy on Female Marital Happiness and Divorce

description: Since the 1980s a reverse gender gap has emerged in post-secondary completion, with women obtaining Bachelor’s degrees at increasingly higher rates than men. Many suggest this creates a smaller market of marriageable men. Using IPUMS census data for female respondents, I find that as relative education levels increase for women, educational hypogamy has not increased drastically but divorce rates have increased and marriage has become less common. I also find that educational hypogamy has a negative association with marital happiness, and also may have a negative association on the likelihood of getting divorced, while educational hypergamy seems to have a positive association. The effects of age on the model were not very pronounced. Work hypogamy, meanwhile, is associated with an increased likelihood of divorce. It is likely that work hypogamy among women, as it is much rarer than educational hypogamy, is still stigmatized in some way.
The Tower and 'Rhenish Helm' Spire of St Mary's Church, Sompting

description: Sussex Archaeological Collections, 126, 105-144
description: A detailed study of the tower and spire in 1984, supported by documentary research and scientific dating evidence, has permitted a better understanding of the dates of their construction. The west end of an Anglo-Saxon church was heightened to form a tower at the end of the 11 th century when a tower arch was inserted incorporating earlier decorated stones as imposts. Various alternative reconstructions for the roof on the original tower are proposed but it seems most likely that the original roof was in the form of a helm spire, supported on either wooden or the present masonry gables. The present helm spire was built in the first quarter of the 14th century, possibly as a result of the church being taken over by the Knights Hospitaler. Later alterations and repairs are noted.

description: Despite decades of research, the relationship between the quality of science and the value of inventions has remained unclear. We present the result of a large-scale matching exercise between 4.8 million patent families and 43 million publication records. We find a strong positive relationship between quality of scientific contributions referenced in patents and the value of the respective inventions. We rank patents by the quality of the science they are linked to. Strikingly, high-rank patents are twice as valuable as low-rank patents, which in turn are about as valuable as patents without direct science link. We show this core result for various science quality and patent value measures. The effect of science quality on patent value remains relevant even when science is linked indirectly through other patents. Our findings imply that what is considered "excellent" within the science sector also leads to outstanding outcomes in the technological or commercial realm.
