description: The non-equilibrium quantum field dynamics is usually described in the closed-time-path formalism. The initial state correlations are introduced into the generating functional by non-local source terms. We propose a functional approach to the Dyson-Schwinger equation, which treats the non-local and local source terms in the same way. In this approach, the generating functional is formulated for the connected Green functions and one-particle-irreducible vertices. The great advantages of our approach over the widely used two-particle-irreducible method are that it is much simpler and that it is easy to implement the procedure in a computer program to automatically generate the Feynman diagrams for a given process. The method is then applied to a pure gluon plasma to derive the gauge-covariant transport equation from the Dyson-Schwinger equation in the background covariant gauge. We discuss the structure of the kinetic equation and show its relationship with the classical one. We derive the gauge-covariant collision part and present an approximation in the vicinity of equilibrium. The role of the non-local source kernel in the non-equilibrium system is discussed in the context of a free scalar field.

Development of High Early-Strength Concrete for Accelerated Bridge Construction Closure Pour Connections
Creators: name: Castine, Stephanie
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Accelerated bridge construction (ABC) has become a popular alternative to using traditional construction techniques in new bridge construction and existing bridge deck replacement because of the reduction of time spent in field activities. A key feature of bridges built using ABC techniques is the extensive use of prefabricated components. Prefabricated components are joined in the field using small volume closure pours involving high performance materials (steel and concrete) to ensure adequate transfer of forces between components. To date, the materials developed for closure pours have been based on proprietary components, so a need has arisen for development of mixes that use generic components. The goal of this research was to create a method to develop concrete mixtures that are designed using generic constituents and that satisfy performance requirements of accelerated bridge construction closure pours in New England, primarily high early strength and long-term durability. Two concrete mixtures were developed with a primary goal of reaching high-early strength while maintaining constructability. The secondary goal of the concrete mixtures was to be durable; therefore, measures were taken during the development of the concrete mixture to generate a mixture that also had durable properties.

description: In order to simulate an environment resembling to that of space and to envisage the difficulties that may crop-up during space voyage, a closed environment system - MICROCOSM was established using plastic films with crowded living conditions, controlled lighting and other physical factors. Four cycles of matter turn-over in the biotic cycle were carried out. The results obtained were used for designing a Closed Environment System containing man, plants, soil and aquaculture with a bio-regeneration module under microgravity conditions. Sub-systems controlling the ambient temperature, moisture, carbon dioxide concentration, light and air flow around the vegetation and supply of recycled water and nutrients are rather challenging. Plants with protracted shoot are more difficult to grow than those with short ones like cabbage, carrot, potato, radish and tomato etc.

Regional Expression In The Renovation Of Remote Historic Villages
Creators: name: chen, Jie
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Due to the fast-pace of urban development, there is a large demand for labor in big cities in China. Also, because of a huge income gap between countryside and cities, an increasing number of youths in rural areas have chosen to leave their homes and transfer to the cities causing a rapid decline of population and the vacancy of properties. This phenomenon is referred to as “Hollow Village”. Especially in case of some remote historic villages, due to labor turnover, villages which has precious historic and culture value are abandoned and stopped from development. Only children and elders are left in those villages without prospects.
Ling is among those backward areas. It has held a vital place in Huizhou culture during the history of Chinese rural settlements and contains a few ancient villages which share some common but features while being distinctive. However, with the lag of population and development, it is gradually losing its style and forgotten by moderns. This district needs to be preserved and developed while its feature is protected. 
This thesis will analyze Ling’s current living conditions, tracing to its cultural and social changes through history and seeking to find architectural solutions, also by offering strategies that can lead to the revitalization of the place, while simultaneously creating some economic stimulations. The thesis aims to developing people’s sense of belonging and identity towards such villages, in the hope of revving as a prototype for other remote villages in China.
A low-scale flavon model with a $Z_N$ symmetry

Subjects: subject: High Energy Physics - Phenomenology (hep-ph)

description: We propose a model that explains the fermion mass hierarchy by the Froggatt-Nielsen mechanism with a discrete $Z_N^F$ symmetry. As a concrete model, we study a supersymmetric model with a single flavon coupled to the minimal supersymmetric Standard Model. Flavon develops a TeV scale vacuum expectation value for realizing flavor hierarchy, an appropriate $μ$-term and the electroweak scale, hence the model has a low cutoff scale. We demonstrate how the flavon is successfully stabilized together with the Higgs bosons in the model. The discrete flavor symmetry $Z_N^F$ controls not only the Standard Model fermion masses, but also the Higgs potential and a mass of the Higgsino which is a good candidate for dark matter. The hierarchy in the Higgs-flavon sector is determined in order to make the model anomaly-free and realize a stable electroweak vacuum. We show that this model can explain the fermion mass hierarchy, realistic Higgs-flavon potential and thermally produced dark matter at the same time. We discuss flavor violating processes induced by the light flavon which would be detected in future experiments.

“Hagene, der vil ungetriuwe man”? Courtly Rivalry, Loyalty Conflict, and the Figure of Hagen in the Nibelungenlied
Creators: name: DeVane Brown, Katherine
Publisher: name: University of Massachusetts Amherst
Year: 2014

description: The variety of scholarly approaches to the Middle High German poem Das Nibelungenlied has generated a wide range of conflicting analyses of the character of Hagen, a figure who plays a key role in both the plot and the interpretation of the work. This thesis proposes that viewing Hagen’s relationship with Siegfried in relation to the poem’s central theme of loyalty (triuwe) allows for an analysis that integrates both the positive and negative aspects of Hagen’s character. By examining the depiction of courtly rivalry in four contemporary Middle High German works (Herzog Ernst B, Wolfdietrich A, Tristan, and Parzival), I outline the basic features of this common medieval narrative structure and then apply the same framework to a close reading of the relationship between Hagen and Siegfried in the Nibelungenlied. I also argue that the incorporation of the courtly rivalry motif as a unifying theme of the text allows the poet to take a stance on the broader issue of loyalty conflict, a topic which appears frequently in contemporary literature and had particular relevance within the political climate of medieval Germany. My reading of the character of Hagen can thus hopefully shed new light on the thematic structure of the Nibelungenlied as well as on the relationship between the poem and the literary and historical context in which it was written.
Utopia In The Apocalypse: Creating A Framework Of Survival Systems

Publisher: name: University of Massachusetts Amherst

description: As medicines continue to evolve, as well as our tendency to misuse and abuse them, viruses become more and more resilient. While the flu is largely an inconvenience which at its worst may result in a missed day of work, it bears the risk of returning to the days of old when it was a terminal disease. With the imminent risk of resistant super viruses emerging,New York Cityhas taken precautions to prepare for the worst case scenario. If deemed necessaryNew Yorkhas plans to completely quarantine and isolate the city from the world. This provides us with the perfect opportunity to ask the questionHollywoodhas become fascinated with…How would a city likeNew Yorkfunction and survive in the Apocalypse? The answer is not as simple as waiting out the storm; with limited resources, no access to the outside world and a crippled infrastructure.
What this thesis also aims to experiment with is the notion of not only barely surviving, but the creation of a new way of life; a truly self – sufficient city, perhaps even creating a Utopian society. This can be analyzed with a systems based approach regarding the different scales of life; from the survival of the individual, the function of the physical shells remaining, and finally the development of a Dynamic City composed new communities

description: Much has been learned about basic biology from studies of insect model systems. The pre-eminent insect model system, Drosophila melanogaster, is a holometabolous insect with a derived mode of segment formation. While additional insect models have been pioneered in recent years, most of these fall within holometabolous lineages. In contrast, hemimetabolous insects have garnered less attention, although they include agricultural pests, vectors of human disease, and present numerous evolutionary novelties in form and function. The milkweed bug, Oncopeltus fasciatus (order: Hemiptera)—close outgroup to holometabolous insects—is an emerging model system. However, comparative studies within this order are limited as many phytophagous hemipterans are difficult to stably maintain in the lab due to their reliance on fresh plants, deposition of eggs within plant material, and long development time from embryo to adult.
title: Reforming the United Nations
Creators: name: Kostakos, Georgios
Publisher: name: University of Kent
Year: 2022

description: The thesis deals with the financial crisis that the United Nations faced starting in 1985 when the US Congress decided to withhold a significant part of the US contribution to the UN regular budget in order to force a greater say for the major contributors on budgetary issues, budgetary restraint and greater efficiency. The UN responded by the adoption of resolution 41/213 of 19 December 1986 that was based on the recommendations of a Group of High-level Intergovernmental Experts ("G-18") set up a year earlier. A new system was introduced regarding the formulation of the regular budget of the United Nations Organisation and a broader process of reform was initiated including a restructuring of the Secretariat and of the intergovernmental machinery in the economic and social fields. After an introductory chapter (Chapter I), the thesis examines the UN problems at the budgetary/financial and administrative/structural levels, the solutions proposed from within and without the United Nations established framework and the actual attempts at reform (Chapters II and ifi). The realisation that the implementation of reforms is rather disjointed and often unsuccessful (e.g. the failure to restructure the intergovernmental machi.neiy) prompts a search for the deeper causes of the UN problems at the political level and the attitudes of the main actors, namely the USA, the USSR, some up-and-coming states, notably Japan, the Third World states and, finally, of the UN Secretary-General and the Secretariat (Chapter 1V). Although the financial crisis may have subsided since 1988 and the USA seem committed to paying up their dues, the deeper UN crisis of identity has not been resolved and is expected to resurface if no bold steps are taken. In that direction, some possible alternative courses for the UN in the future are discussed drawing upon theory and practice (Chapter

description: We classify $N{=}1$ $d=4$ kinematical and aristotelian Lie superalgebras with spatial isotropy, but not necessarily parity nor time-reversal invariance. Employing a quaternionic formalism which makes rotational covariance manifest and simplifies many of the calculations, we find a list of $43$ isomorphism classes of Lie superalgebras, some with parameters, whose (nontrivial) central extensions are also determined. We then classify their corresponding simply-connected homogeneous $(4|4)$-dimensional superspaces, resulting in a list of $27$ homogeneous superspaces, some with parameters, all of which are reductive. We determine the invariants of low rank and explore how these superspaces are related via geometric limits.

An Incremental Intervention In Jakarta: An Empowering Infrastructural Approach For Upgrading Informal Settlements
Creators: name: Counihan, Christopher H.
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: Incrementalism is a growing movement within multiple design disciplines that approaches design with sustainable, social, and resilient aims structured around participatory, infrastructural, and phased approaches to design. Carefully considered structural and independent infrastructural frameworks allow infill and accretion according to the demands and needs of individuals and communities. This paper outlines the theories, case studies, and conditions driving incrementalism. My research has informed my project proposal for an incremental upgrade of a slum located in Jakarta using a phased, soft infrastructural, resident facilitated upgrade and development strategy creating new housing units, productive landscapes, and urban form. Incremental development will foster the social aims of my project, while affordably, equitably, and efficiently upgrading the standards of living for slum dwellers within the Waduk Pluit community.

description: Antihydrogen atoms are routinely formed at the Antiproton Decelerator at CERN in a wide range of Rydberg states. To perform precision measurements, experiments rely on ground state antimatter atoms which are currently obtained only after spontaneous decay. In order to enhance the number of atoms in ground state, we propose and assess the efficiency of different methods to stimulate their decay. First, we investigate the use of THz radiation to simultaneously couple all n-manifolds down to a low lying one with sufficiently fast spontaneous emission toward ground state. We further study a deexcitation scheme relying on state-mixing via microwave and/or THz light and a coupled (visible) deexcitation laser. We obtain close to unity ground state fractions within a few tens of microseconds for a population initiated in the n=30 manifold. Finally, we study how the production of antihydrogen atoms via stimulated radiative recombination can favourably change the initial distribution of states and improve the overall number of ground-state atoms when combined with the stimulated deexcitation proposed.

description: This paper gives a brief review on types of subsidies and how they work in theory. The paper identified three types of subsidies: subsidies that increase revenue, subsidies that lower the cost of production, and subsidies that are not linked to production or input. With the use of graphic examples to describe the partial effects of subsidies on supply and demand, the following findings were obtained: one, for producers to sell more, they will need to produce more, and in order to produce more, a higher input level is required, which depends on the marginal productivity of the inputs; two, the larger the elasticity for supply and demand of input (the more responsive supply and demand are to changes in the price of the input), the larger quantity of input used for a given level of support, and thereby increasing the associated environmental damage from the use of that particular input; three, for a given demand curve, a shallow supply curve (reflecting a large price elasticity of supply) will yield larger volume effects in response to a certain change in price compared to a steep supply curve and vise a verse. Finally, the study found input subsidy is an example of subsidies that lower the cost of production, and direct income support or unconditional lump sum support to an industry as an example of subsidies that are not linked to production or input.

description: Strong gravitational lensing is a promising way of uncovering the nature of dark matter, by finding perturbations to images that cannot be well accounted for by modeling the lens galaxy without additional structure, be it subhalos (smaller halos within the smooth lens) or line-of-sight (LOS) halos. We present results attempting to infer the presence of substructure from images without requiring an intermediate step in which a smooth model has to be subtracted, using a simple convolutional neural network (CNN). We find that the network is only able to infer the presence of subhalos with $>75\%$ accuracy when they have masses of $\geq 5 \times 10^9$M$_{\odot}$ if they lie within the main lens galaxy. Since less massive foreground LOS halos can have the same effect as higher mass subhalos, the CNN can probe lower masses in the halo mass function. The accuracy does not improve significantly if we add a population of less massive subhalos. With the expectation of experiments such as HST and Euclid yielding thousands of high-quality strong lensing images in the next years, having a way of analyzing images quickly to identify candidates that merit further analysis to determine individual subhalo properties while preventing extensive resources being used for images that would yield null detections could be very useful. By understanding the sensitivity as a function of substructure mass, non-detections could be combined with the information from images with substructure to constrain the cold dark matter scenario, in particular if the sensitivity can be pushed to lower masses.

description: The Varroa mite is a threat to honey bees and beekeepers across the U.S. and is suspected to be one contributor to colony collapse disorder (CCD). In 2006, Varroa Sensitive Hygiene (VSH) bees were developed in response to this problem in the beekeeping industry. The hygienic behavior of VSH bees helps reduce susceptibility of colonies to Varroa mites, results in stronger colonies and decrease susceptibility to CCD. The objective of this paper is to identify factors that significantly influence the adoption of VSH technology. A probit model is used to identify factors these factors. Results indicate risk aversion, education and income significantly influence adoption decision.
UMASS Dining Hall. A Path to Resiliency

description: This thesis investigates integration of University’s Dining Hall and Emergency Shelter in terms of their inter-related sustainability factors; the ability to take advantage of the site to harvest, store, grow and learn about all aspects of food production, and to provide a safe place to stay during times of emergency.
The program, in addition to being a dining hall, is concerned with teaching about food science and culinary studies, relating to the agrarian history of the University of Massachusetts and bringing that history into the current moment with the resurgence of localized food production and in support of the UMass award winning dining halls.
This program is designed for students to develop an understanding of food, water and environmental sustainable systems. Also in close relationship to the life essentials of food and water, this thesis addresses the need of the university to increase the existing shelter footprint on campus.
Based on recent climate experiences, we acknowledge there will be times of severe weather which can threaten our safety or even lives. During power outages and dangerous conditions resulting from severe storms, tornadoes, or earthquakes, the university is working to be able to provide shelter for people from our community and ensure them with a well-equipped and warm place to stay.
Lastly, the building is designed to have flexible spaces that can be programmed to house classes and events needed to provide learning and funding opportunities during summer time while the university is on break. All aspects of this design intertwine within each other creating an integrated system which is based on people, sun, and water circulation. The “systems” are designed to educate students as well as visitors; how to grow food, harvest green energy, and collect rain water for garden use. It gives a resource for food, energy and water on a daily basis while during emergency, crucial for survival.

description: Obesity rates are recognized to be at epidemic levels throughout much of the world, posing significant threats to both the health and financial security of many nations. The causes of obesity can vary but are often complex and multifactorial, and while many contributing factors can be targeted for intervention, an understanding of where these interventions are needed is necessary in order to implement effective policy. This has prompted an interest in incorporating spatial context into the analysis and modeling of obesity determinants, especially through the use of geographically weighted regression (GWR).

description: According to Belinsky, Khalatnikov and Lifshitz, gravity near a space-like singularity reduces to a set of decoupled one-dimensional mechanical models at each point in space. We point out that these models fall into a class of conformal mechanical models first introduced by de Alfaro, Fubini and Furlan (DFF). The deformation used by DFF to render the spectrum discrete corresponds to a negative cosmological constant. The wave function of the universe is the zero-energy eigenmode of the Hamiltonian, also known as the spherical vector of the representation of the conformal group SO(1,2). A new class of conformal quantum mechanical models is constructed, based on the quantization of nilpotent coadjoint orbits, where the conformal group is enhanced to an ADE non-compact group for which the spherical vector is known.

description: With the development of low order scaling methods for performing Kohn-Sham Density Functional Theory, it is now possible to perform fully quantum mechanical calculations of systems containing tens of thousands of atoms. However, with an increase in the size of system treated comes an increase in complexity, making it challenging to analyze such large systems and determine the cause of emergent properties. To address this issue, in this paper we present a systematic complexity reduction methodology which can break down large systems into their constituent fragments, and quantify inter-fragment interactions. The methodology proposed here requires no a priori information or user interaction, allowing a single workflow to be automatically applied to any system of interest. We apply this approach to a variety of different systems, and show how it allows for the derivation of new system descriptors, the design of QM/MM partitioning schemes, and the novel application of graph metrics to molecules and materials.

description: We analyze the ratio of branching ratios R=BR(H->b b-bar)/BR(H->tau^+ tau^-) of Higgs boson decays as a discriminant quantity between supersymmetric and non-supersymmetric models. This ratio receives large renormalization-scheme independent radiative corrections in supersymmetric models at large \tanβ, which are absent in the Standard Model or Two-Higgs-doublet models. These corrections are insensitive to the supersymmetric mass scale. A detailed analysis in the effective Lagrangian approach shows that, with a measurement of +-21% accuracy, the Large Hadron Collider can discriminate between models if the CP-odd Higgs boson mass is below 900 GeV. An e+e- Linear Collider at 500 GeV center of mass energy can discriminate supersymmetric models up to a CP-odd Higgs mass of ~ 1.8 TeV.

Experimental Study on Viscoelastic Fluid-Structure Interactions
Creators: name: Dey, Anita Anup
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: It is well known that when a flexible or flexibly-mounted structure is placed perpendicular to the flow of a Newtonian fluid, it can oscillate due to the shedding of separated vortices at high Reynolds numbers. If the same flexible object is placed in non-Newtonian flows, however, the structure's response is still unknown. The main objective of this thesis is to introduce a new field of viscoelastic fluid-structure interactions by showing that the elastic instabilities that occur in the flow of viscoelastic fluids can drive the motion of a flexible structure placed in its path. Unlike Newtonian fluids, the flow of viscoelastic fluids can become unstable at infinitesimal Reynolds numbers  due to the onset of a purely elastic flow instability. This instability occurs in the absence of nonlinear effects of fluid inertia and the Reynolds number of the flows studied here are in the order of 10-4. When such an elastic flow instability occurs in the vicinity of a flexible structure, the fluctuating fluid forces exerted on the structure grow large enough to cause a structural instability which in turn feeds back into the fluid resulting in a flow instability. Nonlinear periodic oscillations of the flexible structure are observed which have been found to be coupled to the time-dependent growth and decay of viscoelastic stresses in the wake of the structure. Presented in this thesis are the results of an investigation of the interaction occurring in the flow of a viscoelastic wormlike micelle solution past a flexible rectangular sheet. The structural geometries studied include: flexible sheet inclinations at 20°, 45° and 90° and flexible sheet widths of 5mm and 2.5mm. By varying the flow velocity, the response of the flexible sheet has been characterized in terms of amplitude and frequency of oscillations. Steady and dynamic shear rheology and filament stretching extensional rheology measurements are conducted in order to characterize the viscoelastic wormlike micelle solution. Bright field images show the deformation of the flexible sheet during an unstable oscillation while flow-induced birefringence images highlight the viscoleastic fluid stresses produced in the wake of the flexible sheet.

description: We introduce a saturation model for photon-photon interactions, based on a QCD dipole picture of high energy scattering. The two-dipole cross-section is assumed to satisfy the saturation property. This pomeron-like contribution is supplemented with QPM and non-pomeron reggeon contributions. The model gives a very good description of the data on the gamma-gamma total cross-section, on the photon structure function F_2^gamma(x,Q^2) at low x and on the gamma*-gamma* cross-section.

Designing Hedda: Questioning the Canonical Play Hedda Gabler, as a Feminist Text Through Abstraction
Creators: name: Eddy, Bethany
Publisher: name: University of Massachusetts Amherst
Year: 2017

description: A thorough reflection on the process of costume design for the theatrical production of Hedda. An adaptation of Hedda Gabler, by Henrik Ibsen, translated by Eva Le Gallienne, edited by Finn Lefevre and Directed by Christina Pellegrini. Performed at The Rand Theater, University of Massachusetts Amherst, February 24th to March 4th, 2017.
Ibsen is considered “The Father of Modern Drama”, with Hedda Gabler as one of his most widely performed plays. Hedda Gabler in the 1890’s was a disruptive reflection of society, and is considered by many to be a feminist work. I disagree with this assessment of the text. There are relevant gendered issues present within Hedda Gabler, however the play presents suicide as the only solution. Hedda Gabler could become a feminist work if presented in a way to address the issues raised.
A collaborative, devised process, was used to produce this play. This created an iterative process of design reacting to discoveries made throughout the process. Costume design, in concert with set design, functioned as a visual medium creating the abstracted world of Hedda. Tracking artistic and social influences on costume design for Hedda; I provide the evolution of the design from analysis to production while examining the design’s influence on show development, and role in the devising process. Our show featured a seven women ensemble, each actress alternatively portraying Hedda and each of the other characters within the play. Set in a flat, surrealistic, paper covered library, the paper costume constructs blended with the background when each was not in use. This role switching resulted in the presentation of Hedda as a widely felt feminine experience rather than a singularity. Through the abstraction of Hedda Gabler we presented a production that challenged the canonical text while reviving its feminist dialogue with our contemporary moment.

description: Let $G$ be a finite group and $W$ be a faithful representation of $G$ over {\bf C}. The group $G$ acts on the field of rational functions $\mathbf C(W)$. The aim of this paper is to give a description of the unramified cohomology group of degree 3 of the field of invariant functions $\mathbf C(W)^G$ in terms of the cohomology of $G$ when $G$ is a group of odd order. This enables us to give an example of a group for which this field is not rational, although its unramified Brauer group is trivial.
