description: ABSTRACT Title of Document: THE PASSENGERS OF THE SHIP GILBERT IN 1721: BRITISH FEMALE CONVICT TRANSPORTATION FROM LONDON TO ANNAPOLIS.  Teresa Bass Foster M.A. Historical Studies, 2011  Directed by Dr. Marjoleine Kars Associate Professor, History Department This thesis examines the experience of eighteenth-century convict women as part of a system of bond slavery in British colonial America. Throughout most of the eighteenth-century, convict women were regularly shipped from London to the British Chesapeake colonies. Transported from Newgate Prison aboard ships owned by London merchants, convict women endured a middle passage, often in a ship that previously plied African slave routes. Sold to Maryland planters, these women became bond slaves for a fixed term of seven to fourteen years, during which time their labor, productive and reproductive, was the sole property of a master/owner. I argue that the conditions of bond slavery differed for male and female convicts by examining individual and group experiences of the convicts aboard a representative ship, the Gilbert in 1721. This study will contribute to a sparse body of historical knowledge on the convict experience, one that often assumes a male normative subject in spite of the presence of women aboard every transport. Tens of thousands of male and female convicts were transported to the Chesapeake colonies, most destined for Maryland, and yet we know little about their lives.  This paper expands upon the work of historians who have argued for the importance of colonial convict studies and it discusses the actual convict experience as an example of the multiplicity of slaveries present in British colonial America. Research methodology included eighteenth-century records at the Maryland State Archive, London Metropolitan Archives, and National Archives at Kew.
Four electrons in a two-leg Hubbard ladder: exact ground states

description: In the case of a two-leg Hubbard ladder we present a procedure which allows the exact deduction of the ground state for the four particle problem in arbitrary large lattice system, in a tractable manner, which involves only a reduced Hilbert space region containing the ground state. In the presented case, the method leads to nine analytic, linear, and coupled equations providing the ground state. The procedure which is applicable to few particle problems and other systems as well is based on an r-space representation of the wave functions and construction of symmetry adapted orthogonal basis wave vectors describing the Hilbert space region containing the ground state. Once the ground state is deduced, a complete quantum mechanical characterization of the studied state can be given. Since the analytic structure of the ground state becomes visible during the use of the method, its importance is not reduced only to the understanding of theoretical aspects connected to exact descriptions or potential numerical approximation scheme developments, but is relevant as well for a large number of potential technological application possibilities placed between nano-devices and quantum calculations, where the few particle behavior and deep understanding are important key aspects to know.

The Experience of an Enlisted US Army Soldier During and After the Punitive Expedition and World War I: Thomas F. Cunningham, a case study.

Subjects: Enlisted soldier

description: This thesis explores the experience of Thomas F. Cunningham as an enlisted soldier during the Punitive Expedition and World War I. His experience is both typical and unique as compared to that of other soldiers during the same period. He grew up in the deep South and in a family where he learned a variety of definitions of service, from his faith, his family's economic situation, and experiences of his family members, especially his maternal grandfather and father. While the majority of World War I soldiers were drafted, Cunningham had enlisted and served along the Texas-Mexican border during the Punitive Expedition. However, his experience is also typical of World War I soldiers because he served in France, was injured and gassed, and later expected the US government to compensate him financially for his service. He had paid into the War Risk Insurance program while enlisted and received benefits after returning home and being discharged from the military. Eventually, this financial compensation is denied and Cunningham fought as an individual, similar to those that fought collectively in events such as the Bonus March, for the reinstatement of these benefits. His experience as an individual during this period, highlights both the micro and macro history of the period.

description: In kesterite CZTSSe solar cell research, an asymmetric crystallization profile is often obtained after annealing, resulting in a bilayered or double-layered absorber. So far, only segregated pieces of research exist to characterize this double layer, its formation dynamics and its effect on the performance of devices. Here, we review the existing research on double-layered kesterites and evaluate the different mechanisms proposed. Using a cosputtering-based approach, we show that the two layers can differ significantly in morphology, composition and optoelectronic properties, and complement the results with a statistical dataset of over 850 individual CZTS solar cells. By reducing the absorber thickness from above 1000 nm to 300 nm, we show that the double layer segregation is alleviated. In turn, we see a progressive improvement in the device performance for lower thickness, which alone would be inconsistent with the known case of ultrathin CIGS solar cells. By comparing the results with CZTS grown on monocrystalline Si substrates, without a native Na supply, we show that the alkali metal supply does not determine the double layer formation, but merely reduces the threshold for its occurrence. Instead, we propose that the main formation mechanism is the early migration of Cu to the surface during annealing and formation of Cu2-xS phases, in a self-regulating process akin to the Kirkendall effect. We comment on the generality of the mechanism proposed, comparing our results to other synthesis routes, including our own in-house results from solution processing and pulsed laser deposition of sulfide and oxide-based targets. Although the double layer occurrence largely depends on the kesterite synthesis route, the common factors determining the double layer occurrence appear to be the presence of metallic Cu and/or a chalcogen deficiency in the precursor matrix.

description: The visual STELLA echelle spectrograph (SES-VIS) is a new instrument for the STELLA-II telescope at the Izaña observatory on Tenerife. Together with the original SES spectrograph - which will still be used in the near IR - and a new H&K-optimized spectrograph, which is currently in the design phase, it will extend the capabilities of STELLA with the follow up of planetary candidates from space missions (TESS, PLATO2). SES-VIS is optimized for precise radial velocity determinations and long term stability. We have developed a ZEMAX based software package to create simulated spectra, which are then extracted using our new data reduction package developed for the PEPSI spectrograph. The focus in this paper has been put on calibration spectra, and the full range of available calibration sources (flat field, Th-Ar, and Fabry-Perot etalon), which can be compared to actual commissioning data once they are available. Furthermore we tested for the effect of changes of the environmental parameters to the wavelength calibration precision.

description: Ribosomal protein L4 (RPL4) is a large ribosomal subunit protein that is structurally conserved in all kingdoms of life. This protein is a component of the 90S pre-ribosomal particle that initiates ribosomal assembly on the primary (35S) transcript. Here I show that in vivo repression of Rpl4p synthesis in S. cerevisiae results in severe loss of 60S ribosomal subunits and affects progression of the cell cycle. Analysis of rRNA processing suggests that these effects are associated with a block in the processing of the 27SA3 precursor RNA into 5.8S and 25S rRNA as well as a delay in processing of 35S precursor. More surprisingly, depletion of Rpl4p results in a unique bi-budded phenotype, with multiple cell cycle defects mainly affecting mitotic exit. To further characterize the role of RPL4 in cell cycle progression, I isolated temperature-sensitive L4 mutants. To date I have analyzed one of these mutants. Six hours after a temperature shift of this mutant, cells are uniformly arrested in S?G2 progression with single large bud, unseparated genetic material, and emerging spindle apparatus. Interestingly, the mutation lies in the extended tentacles of RPL4, which is disposable in prokaryotes, but appears to play a key role in the functioning of this protein in eukaryotes. All the above data indicate an important extra-ribosomal function of RPL4 in orchestrating ribosome biogenesis with cell cycle progression in S.cerevisiae. Currently, we are attempting to define more precisely how Rpl4p is involved in these essential cellular phenomena.

description: We study the fatigue fracture of disordered materials by means of computer simulations of a discrete element model. We extend a two-dimensional fracture model to capture the microscopic mechanisms relevant for fatigue, and we simulate the diametric compression of a disc shape specimen under a constant external force. The model allows to follow the development of the fracture process on the macro- and micro-level varying the relative influence of the mechanisms of damage accumulation over the load history and healing of microcracks. As a specific example we consider recent experimental results on the fatigue fracture of asphalt. Our numerical simulations show that for intermediate applied loads the lifetime of the specimen presents a power law behavior. Under the effect of healing, more prominent for small loads compared to the tensile strength of the material, the lifetime of the sample increases and a fatigue limit emerges below which no macroscopic failure occurs. The numerical results are in a good qualitative agreement with the experimental findings.

description: Asset misappropriation (AM) cases involve the theft or unauthorized use of an organisation's assets for personal gain. It is important to note that AM in the public sector can have serious consequences, such as losing public funds and public trust and undermining essential public services. As a result, this type of fraud is regarded as a serious threat to the country's financial stability and sovereignty. The study explores fraudsters' motives concerning asset misappropriation in the Malaysian security apparatus (SA). An exploratory study was conducted considering the sensitive job nature of the SA. The study applied semi-structured interview techniques to achieve the objectives. This method is often used to get rich and relevant data from respondents. The study applied Fraud Diamond Theory to examine factors causing asset misappropriation. The study concluded that common and control mechanisms have specific weaknesses, especially concerning asset management. Further, existing SOPs require upgradation and should be aligned with contemporary best practices. The study found that all elements of the Diamond Fraud Theory significantly affect the behaviour of perpetrators. Therefore, the study suggested an exemplary role of seniors and robust whistle-blowing culture to yield better results against perpetrators.

description: This thesis chronicles the process of the desegregation of public recreation spaces in Baltimore from 1935-1956. The struggle against segregated public parks in Baltimore shows how actions by everyday people often set the agenda for the actions of institutional organizations like the NAACP, and how such efforts create social change in spaces outside of mandated areas of societal interactions. Without the general public supporting integration for themselves, places like parks would remain effectively segregated, even after discriminatory policies were removed. While a significant portion of this project relates to legal cases, these cases were brought forth only after protest actions by individuals and community-based organizations. The fight culminated in the official desegregation of public park facilities in 1955. Newspaper reports and the official minutes of the Baltimore Bureau of Recreation and Parks uncover the events of these protests; oral histories to bring to light the individual motivations which propelled such actions. Finally, local newspaper reports, oral histories, and published accounts of the events also create a broader picture of how the various communities in Baltimore viewed the fight to desegregate the public parks.

description: Rotational bands are commonplace in the spectra of atomic nuclei. Inspired by early descriptions of these bands by quadrupole deformations of a liquid drop, Elliott constructed a discrete nucleon representations of $\mathrm{SU}(3)$ from fermionic creation and annihilation operators. Ever since, Elliott's model has been foundational to descriptions of rotation in nuclei. Later work, however, suggested the symplectic extension $\mathrm{Sp}(3,R)$ provides a more unified picture. We decompose no-core shell-model nuclear wave functions into symmetry-defined subspaces for several beryllium isotopes, as well as $^{20}$Ne, using the quadratic Casimirs of both Elliott's $\mathrm{SU}(3)$ and $\mathrm{Sp}(3,R)$. The band structure, delineated by strong $B(E2)$ values, has a more consistent description in $\mathrm{Sp}(3,R)$ rather than $\mathrm{SU}(3)$. {In particular, we confirm previous work finding in some nuclides strongly connected upper and lower bands with the same underlying symplectic structure.

Unique representation of an inverse-kinetic theory for incompressible Newtonian fluids

description: Fundamental aspects of inverse kinetic theories for the incompressible Navier-Stokes equations [Ellero and Tessarotto, 2004, 2005] include the possibility of defining uniquely the kinetic equation underlying such models and furthermore, the construction of a kinetic theory implying also the energy equation. The latter condition is consistent with the requirement that fluid fields result classical solutions of the fluid equations. These issues appear of potential relevance both from the mathematical viewpoint and for the physical interpretation of the theory. Purpose of this work is to prove that under suitable prescriptions the inverse kinetic theory can be determined to satisfy such requirements.

description: Ten Clementines Hitting the Floor is an installation consisting of four screens, three tables, one vase, three plastic flowers, one white tablecloth, and three fake lemons. One suspended screen, on which is projected a sun that never sets, hovers over three television sets, on which play loops of one- to two-second clips that I recorded with an Apple iPhone. This portable device allowed me to realize Gene Youngblood's 1970 forecast of an "expanded cinema" and to update his theories to what I call "accumulated cinema." Each clip represents a moment in which I was present and involved no post editing of clip size or structure. The clips were recorded in real time and remain that way.  The installation is an exploration of time, accumulation, and the construction of the reality of self. Albert Camus's philosophy of the absurd, discussed in The Myth of Sisyphus and Other Essays, formed the theoretical base from which I examined reality and the construction of self by exploring the notion of knowledge through experience and the importance of the present moment.

First, using a general criteria of Arendt-Batty, we prove the strong stability of our system. Finally, using a frequency domain approach combined with the multiplier method, we prove that the energy of our system decays polynomially with different rates.

description: Short range correlations are introduced using unitary correlation method in a relativistic approach to the equation of state of the infinite nuclear matter in the framework of the Hartree-Fock approximation. It is shown that the correlations give rise to an extra node in the ground-state wave-function in the nucleons, contrary to what happens in non-relativistic calculations with a hard core. The effect of the correlations in the ground state properties of the nuclear matter and neutron matter is studied. The nucleon effective mass and equation of state (EOS) are very sensitive to short range correlations. In particular, if the pion contact term is neglected a softening of the EOS is predicted. Correlations have also an important effect on the neutron matter EOS which presents no binding but only a very shallow minimum contrary to the Walecka model.

description: Bacterial colonization ofimplanted biomedical devicesis themain cause of healthcare-associated infections, estimated to be 8.8 million per year in Europe. Many infections originate from damaged skin, which lets microorganisms exploit injuries and surgical accesses as passageways to reach the implant site and inner organs. Therefore, an effective treatment of skin damage is highly desirable for the success of many biomaterial-related surgical procedures. Due to gained resistance to antibiotics, new antibacterial treatments are becoming vital to control nosocomial infections arising as surgical and post-surgical complications. Surface coatings can avoid biofouling and bacterial colonization thanks to biomaterial inherent properties (e.g., super hydrophobicity), specifically without using drugs, which may cause bacterial resistance. The focus of this review is to highlight the emerging role of degradable polymeric micro- and nano-structures that show intrinsic antifouling and antimicrobial properties, with a special outlook towards biomedical applications dealing with skin and skin damage. The intrinsic properties owned by the biomaterials encompass three main categories: (1) physical-mechanical, (2) chemical, and (3) electrostatic. Clinical relevance in ear prostheses and breast implants is reported. Collecting and discussing the updated outcomes in this field would help the development of better performing biomaterial-based antimicrobial strategies, which are useful to prevent infections.

description: A new path for quantum gas experiments with high resolution is a combination of the advantages of highly uniform optical lattices with the flexibility offered by optical tweezer arrays. Those hybrid tweezer lattices require performant microscope objectives that can simultaneously image individual atoms in the optical lattice and generate diffraction-limited optical tweezers for single-site addressing. In this thesis the imaging performance is characterized for two custom made high-resolution objectives at 399 and 532 nm as well as the tweezer-generation capabilities with 532 nm light.
To this end, we build and optimize an optical test setup that can perform automated focus scans with sub-wavelength axial step size to test the objective point spread function and optical tweezer generation. We confirm diffraction-limited operation in both cases for each objective and in a field of view of 100x100 μm. Furthermore we generate 2D tweezer arrays using two acousto-optical deflectors in a crossed configuration and characterize their shape in 3D. An in-depth discussion on the error estimates and various compensation techniques used for analysis is presented as well. Finally, we successfully integrate the objective into the main setup including the trapping and imaging of ultracold ytterbium atoms in a 5x5 optical tweezer array.

description: Most modern operating systems have adopted the one-to-one thread model to support fast execution of threads in both multi-core and single-core systems. This thread model, which maps the kernel-space and user-space threads in a one-to-one manner, supports quick thread creation and termination in high-performance server environments. However, the performance of time-critical threads is degraded when multiple threads are being run in low-end CE devices with limited system resources. When a CE device runs many threads to support diverse application functionalities, low-level hardware specifications often lead to significant resource contention among the threads trying to obtain system resources. As a result, the operating system encounters challenges, such as excessive thread context switching overhead, execution delay of time-critical threads, and a lack of virtual memory for thread stacks. This paper proposes a state-of-the-art Thread Evolution Kit (TEK) that consists of three primary components: a CPU Mediator, Stack Tuner, and Enhanced Thread Identifier. From the experiment, we can see that the proposed scheme significantly improves user responsiveness (7x faster) under high CPU contention compared to the traditional thread model. Also, TEK solves the segmentation fault problem that frequently occurs when a CE application increases the number of threads during its execution.

description: This Thesis analyzes the 1960s anti-war movement at the University of Maryland, College Park (UMCP), with particular emphasis on the series of protests that occurred in May of 1970.  Over twelve hundred colleges and universities saw protests during that month, with those at Kent State University, which saw four students killed, being the most famous.  UMCP had not been considered a hotbed of student activism, anti-war or otherwise, and the extent of violence and destruction that occurred during May 1970 was far more than what occurred at the majority of campuses.   Also examined are the roots of 1960s student activism at UMCP, and how the various strains of the student movement; civil rights, student rights, and anti-war activity evolved and coalesced, culminating in the protests of May 1970.

However, scaling beyond a few network nodes is currently limited by low spin-photon entanglement rates, resulting from the NV center's low probability of coherent photon emission and collection. Integration into a cavity can boost both values via the Purcell effect, but poor optical coherence of near-surface NV centers has so far prevented their resonant optical control, as would be required for entanglement generation. Here, we overcome this challenge, and demonstrate resonant addressing of individual, fiber-cavity-coupled NV centers, and collection of their Purcell-enhanced coherent photon emission. Utilizing off-resonant and resonant addressing protocols, we extract Purcell factors of up to 4, consistent with a detailed theoretical model. This model predicts that the probability of coherent photon detection per optical excitation can be increased to 10% for realistic parameters - an improvement over state-of-the art solid immersion lens collection systems by two orders of magnitude. The resonant operation of an improved optical interface for single coherent quantum emitters in a closed-cycle cryogenic system at T $\sim$ 4 K is an important result towards extensive quantum networks with long coherence.

description: Business was the focus of Maryland’s colonial gentry and Dr. Charles Carroll and his son, Charles Carroll, barrister, were ideal representatives of this group.  Their pursuit of wealth belied the traditionally accepted view of eighteenth-century gentry as a leisured class who derived their income solely from landed estates and investments.  Nor were the Doctor or Barrister focused only on the production of tobacco.  Instead, their agricultural and non-agricultural ventures displayed a diversity which would be understood and lauded by today’s businessman. With their focus on profit-making and the vagaries of the international market, they were not wedded to the production of tobacco.  Instead, they explored the export of grains, the production of flour, other local and international mercantile ventures, as well as the cutting edge industry of its time, the manufacture of iron.  Even with their determined acquisition of wealth, neither man neglected the markers which established them as members of Maryland’s gentry.  They were men of their times.
Duality and higher Buscher rules in p-form gauge theory and linearized gravity

description: We perform an in-depth analysis of the transformation rules under duality for couplings of theories containing multiple scalars, $p$-form gauge fields, linearized gravitons or $(p,1)$ mixed symmetry tensors. Following a similar reasoning to the derivation of the Buscher rules for string background fields under T-duality, we show that the couplings for all classes of aforementioned multi-field theories transform according to one of two sets of duality rules. These sets comprise the ordinary Buscher rules and their higher counterpart; this is a generic feature of multi-field theories in spacetime dimensions where the field strength and its dual are of the same degree. Our analysis takes into account topological theta terms and generalized $B$-fields, whose behavior under duality is carefully tracked. For a 1-form or a graviton in 4D, this reduces to the inversion of the complexified coupling or generalized metric under electric/magnetic duality. Moreover, we write down an action for linearized gravity in the presence of $θ$-term from which we obtain previously suggested on-shell duality and double duality relations. This also provides an explanation for the origin of theta in the gravitational duality relations as a specific additional sector of the linearized gravity action.

Aggregates for the Practical Cataloger

Subjects: subject: Resource description & access
subject: Cataloging of music

subject: IFLA Library Reference Model

description: Original RDA was somewhat lacking in guidance for resources that represent more than a single expression, leaving much unstated or assumed, relying on catalogers' judgment, or using terms such as "compilation" without actually defining them or explaining their significance for cataloging. The response to this gap in coverage is the aggregate model, which addresses these types of resources in a systematic way. However, the language of the model can seem rather impenetrable. This presentation will attempt to demystify the aggregate model for practical cataloging after the forthcoming implementation of official RDA in 2023, covering: the aggregate model in plain language; collection, augmentation, and parallel aggregates as commonly encountered in music materials; current RDA, LC-PCC PS, and MLA guidance for aggregates; changes in practice from original RDA; practical cataloging examples of each type of aggregate and the relevant instructions.

description: Anaerobic fungi are known to migrate and establish a 3D network of biofilms (microbiomes) and live invisible in the rumen and terrestrial subsurface, deep-sea - marine, and anoxic environment. They deserve our attention to understand anoxic fungal ecology and functions and develop new products and solutions. Such fungi activate unique genes to produce various polysaccharidases deemed essential for degrading plants’ lignocellulosic materials. Nutrient release, recycling, and physical support by anaerobic fungi are crucial for microbiome formation. Multiple reports point to the ability of strictly anaerobic and facultative fungi to adapt and live in anoxic subsurface. Deep-sea sediments and natural anoxic methane-emitting salty waters of sulfidic springs offer suitable habitats for developing prokaryotic-fungal microbiomes. Researchers found a billion-year-old fossil of the fungus-prokaryotic sulfate-reducing consortium buried in deep-sea biospheres. Fungal spores’ ability to migrate, even after germination, through sandy layers demonstrates their potential to move up and down porous geological layers or rock fissures. Selective fungal affinity to specific wood in wood chip arrays might help differentiate viable anaerobic fungi from an anoxic environment for their rapid collection and investigation. New collection methods, cultivation, gene expression, and drug and enzyme activity analyses can boost anaerobic fungal research.
Dynamics and Friction in Double Walled Carbon Nanotubes

description: The goal of this PhD thesis was to characterize the properties of friction in nanotubes and from a more general point of view the understanding of the microscopic origin of friction. Indeed, the relative simplicity of the system allows us to interpret more easily the physical phenomenon observed than in larger systems. In order to achieve this goal, non-equilibrium statistical mechanics permitted first to develop models based on Langevin equations describing the dynamics of rotation and translation in double walled nanotubes. The molecular dynamics simulations then permitted to validate these analytical models, and thus to study general properties of friction such as the dependence on area of contact, temperature and the geometry of the nanotubes. The results obtained shows that friction increases linearly with the sliding velocity or the angular velocity until very high values beyond which non-linearities appear enhancing dissipation. In the linear regime, it is shown that the proportionality factor between the dynamic friction force and the velocity is given by the time integral of the autocorrelation function of the restoring force for the sliding friction and of the torque for the rotational friction. Furthermore, a novel resonant friction phenomenon increasing significantly dissipation was observed for the sliding motion in certain types of nanotubes. The effect arises at sliding velocities corresponding to certain vibrational modes of the nanotubes. When the dynamics is described by the linear friction in velocity, the empirical law stating that friction is proportional to the area of contact is very well verified thanks to the molecular dynamics simulations. On the other hand, friction increases with temperature.
