description: In a human-robot interaction system, the most important thing to consider is the safety of the user. This must be guaranteed in order to implement a reliable system. The main objective of this paper is to generate a safe motion scheme that takes into account the obstacles present in a virtual reality (VR) environment. The work is developed using the MoveIt software in ROS to control an industrial robot UR5. Thanks to this, we will be able to set up the planning group, which is realized by the UR5 robot with a 6-sided prop and the base of the manipulator, in order to plan feasible trajectories that it will be able to execute in the environment. The latter is based on the interior of a vehicle, containing a person (which would be the user in this case) for which the configuration will also be made to be taken into account in the system. To do this, we first investigated the software's capabilities and options for path planning, as well as the different ways to execute the movements. We also compared the different trajectory planning algorithms that the software is capable of using in order to determine which one is best suited for the task. Finally, we proposed different mobility schemes to be executed by the robot depending on the situation it is facing. The first one is used when the robot has to plan trajectories in a safe space, where the only obstacle to avoid is the user's workspace. The second one is used when the robot has to interact with the user, where a dummy model represents the user's position as a function of time, which is the one to be avoided.

description: This work uncovers an explanation behind the daily appearance of women in antebellum Baltimore courtrooms who -- despite their customary legal exclusion -- successfully prosecuted and imprisoned countless men -- including husbands -- on charges of assault and battery. By studying the post-Revolutionary concerns over republicanism, masculinity, moral reform, race, and class, this work reveals how the law tended to bend in the favor of traditionally disempowered, ethnic, and working-class women who suffered from abuse. Reform-minded leaders of Baltimore, in particular, were so concerned with ridding the city of its Mobtown moniker that, in order to gain access to violence-prone men, local Justices of the Peace fostered a localized legal environment in which women could prosecute their injustices. Most importantly, this study uncovers how, after centuries of lawfully sanctioned abuse against women, the antebellum period represents the beginning of a wide-scale community and legal condemnation of intimate violence.

description: We study the Einstein-Maxwell system of equations in spherically symmetric gravitational fields for static interior spacetimes. The condition for pressure isotropy is reduced to a recurrence equation with variable, rational coefficients. We demonstrate that this difference equation can be solved in general using mathematical induction. Consequently we can find an explicit exact solution to the Einstein-Maxwell field equations. The metric functions, energy density, pressure and the electric field intensity can be found explicitly. Our result contains models found previously including the neutron star model of Durgapal and Bannerji. By placing restrictions on parameters arising in the general series we show that the series terminate and there exist two linearly independent solutions. Consequently it is possible to find exact solutions in terms of elementary functions, namely polynomials and algebraic functions.

Two Faces of Toryism:  The Conservative Party in the Second Half of the Twentieth Century
Creators: name: Callahan, Marcella Marie
Publisher: name: Maryland Shared Open Access Repository

Subjects: History, European (0335)

description: The purpose of this paper is to demonstrate the ideological flexibility of conservative ideology based upon the power relationship between the Conservative Party and conservative ideology as shown through analysis of the political memoirs of twentieth century conservative leaders Harold Macmillan and Margaret Thatcher.   Analysis of the political discourse and the historical debate surrounding it highlights the difficulty historians have faced when attempting to bring clarity to the history of the Conservative Party during the twentieth century. Both politicians and historians have attempted to determine a core belief or value system to define what conservatism is, or should be.  However, such a rigid system of authenticity fails to encompass the whole belief system of conservative leaders, and most especially fails to account for leaders during the twentieth century.

Using multi-element comparisons to discriminate between natural and anthropogenic post-depositional additions in estuarine sediments

subject: Sedimentation and deposition Australia New South Wales

description: In most areas of the world, high population centres and heavy industry are located along river systems and provide a catchment wide source of heavy metal pollution along the length of the river system. These anthropogenically derived heavy metal pollutants enter the freshwater river systems and are transported downstream as part of the suspended sediment load. Such metals combine with the suspended sediment such that there is a higher concentration of heavy metals with the finer grained, clay-rich component of the transported sediment. In such cases, the ultimate depositional environment of contaminated sediments bears little relation to the distant source regions of anthropogenic pollution. In an arid country like Australia, there are numerous coastal estuaries that are supplied with sediment transported down catchments that lack both industry and significant population centres. However such coastal estuaries are undergoing rapid population growth, even though in such regions the upstream catchment is notably lacking in population centres and industry. This provides an opportunity to study heavy metal additions and contamination in a post-depositional estuarine saline environment, in which relatively uncontaminated freshwater sediments are input into the system, mainly during seasonal flood events. This study demonstrates that transported sediments, derived from upcatchment, undergo post depositional transformations across the freshwater-marine boundary. As a result of these terrigenous, biogenic, authigenic and anthropogenic changes, estuarine sediments do not necessarily reflect the original source composition. Conservative elements, especially rare earth elements, were used to differentiate between original and post-depositional additions and transformations to the sediments of an estuarine system on the south coast of New South Wales, Australia, to show that metal contamination does not correlate wholly with sediment grain size, but also correlates with proximity to local townships surrounding part of an estuary. Metals such as Pb have been discriminated in terms of original, transported sediment compositions and local pollutant sources. Furthermore, analyses of baseline, spatial and temporal data has generated a methodology and conceptual framework for assessing anomalies, even when concentrations are low within apparently 'pristine' settings. This thesis identifies both natural and anthropogenic processes and contributions to estuarine sediments, and presents a methodology by which metal contamination of sediments and the potential future risks from remobilisation can be quantified.

description: In this note we present upper bounds for the variational eigenvalues of the $p$-Laplacian on smooth domains of complete $n$-dimensional Riemannian manifolds and Neumann boundary conditions, and on compact (boundaryless) Riemannian manifolds. In particular, we provide upper bounds in the conformal class of a given manifold $(M,g)$ for $11$ when we fix a metric $g$. To do so, we use a metric approach for the construction of suitable test functions for the variational characterization of the eigenvalues. The upper bounds agree with the well-known asymptotic estimate of the eigenvalues due to Friedlander. We also present upper bounds for the variational eigenvalues on hypersurfaces bounding smooth domains in a Riemannian manifold in terms of the isoperimetric ratio.

description: Built in 1814, the Peale Museum building in Baltimore, Maryland is often credited as America's first museum building. In the twentieth century, this building housed the Municipal Museum of the City of Baltimore for 60 years. In 1997, the museum closed indefinitely and the historic collections were purchased by an outside institution. A newly-formed Baltimore City Historical Society is attempting to create a History Center within the historic building. This study will investigate the development, growth, and effectiveness of urban historical museums and apply the findings to Baltimore's story of heritage preservation in order to determine whether such an institution should be revived in Charm City. If developed successfully, an institution, commission, or center dedicated to the history of Baltimore's people, neighborhoods, and events, could help create a sense of greater community pride and cohesiveness with its citizens as well as facilitate discussions on social issues.

description: We discuss collider signatures of (1,1)-th Kaluza-Klein (KK) mode vector bosons in the framework of two universal extra dimension model, at a future electron-positron collider. Production of the (1,1)-th KK mode of electro-weak vector bosons (B(1,1), W3(1,1)), are considered in association with a hard photon. Without caring about the decay products of those vector bosons, one can measure the masses of these particles just by looking at the photon energy distribution. Once produced these particles dominantly decay to a pair of jets or to a pair of top quarks. Thus we look for a pair of jets or a pair of top quarks in association with a photon. Upto the kinematic limit of the collider, signals from the B(1,1) production and decay in both the above mentioned channels are greater than the $5σ$ fluctuation of the Standard Model background. However, the number of events from W3(1,1) production and decay is smaller and its detection prospect is not very good.

description: Context:In 2020 May-June, six solar energetic ion events were observed by the Parker Solar Probe/ISoIS instrument suite at 0.35 AU from the Sun. From standard velocity-dispersion analysis, the apparent ion path length is 0.625 AU at the onset of each event. Aims:We develop a formalism for estimating the path length of random-walking magnetic field lines, to explain why the apparent ion pathlength at event onset greatly exceeds the radial distance from the Sun for these events. Methods:We developed analytical estimates of the average increase in pathlength of random-walking magnetic field lines, relative to the unperturbed mean field. Monte Carlo simulations of fieldline and particle trajectories in a model of solar wind turbulence are used to validate the formalism and study the path lengths of particle guiding-center and full-orbital trajectories. The formalism is implemented in a global solar wind model, and results are compared with ion pathlengths inferred from ISoIS observations. Results:Both a simple estimate and a rigorous theoretical formulation are obtained for fieldlines' pathlength increase as a function of pathlength along the large-scale field. From simulated fieldline and particle trajectories, we find that particle guiding centers can have pathlengths somewhat shorter than the average fieldline pathlength, while particle orbits can have substantially larger pathlengths due to their gyromotion with a nonzero effective pitch angle. Conclusions:The long apparent path length during these solar energetic ion events can be explained by 1) a magnetic field line path length increase due to the field line random walk, and 2) particle transport about the guiding center with a nonzero effective pitch angle. Our formalism for computing the magnetic field line path length, accounting for turbulent fluctuations, may be useful for application to solar particle transport in general.
Bifunctional organometallic reagents: preparation and use in annulation sequences
Creators: name: Kaller, Alan Matthew
Publisher: name: University of British Columbia
Year: 2009

description: The use of bifunctional organometallic reagents (182, 35, and 271) to afford novel annulation products, such as the trans-fused bicyclo[3.3.0]octane (236) and bicyclo[4.3.0]nonane (83) systems and highly functionalized cyclopentene (273) systems, was investigated. The bifunctional reagent 132, was obtained in three steps from the bromo alcohol 134 via the alcohol 133 and the tosylate 158. The novel functionalized allylcopper(I) reagents, 162 and 182, were prepared from the corresponding allylstannanes 132 and 183 by treatment with methyllithium followed by CuBr∙Me₂S. These allylcopper(I) reagents were shown to add in a 1,4-fashion to a variety of α,β-unsaturated cyclic ketones (30) to provide ketones of general structures 191 and 192. A general annulation method for the preparation of trans-fused bicyclo[3.3.0]octane and bicyclo[4.3.0]nonane systems from a cyclopentanone system 61 was also developed. A palladium(O) catalyzed methoxycarbonylation of the alkenyl triflate 67, obtained from the keto ketal 61, provided the α,β-unsaturated ester 68, which was converted into the corresponding aldehyde 71. Conjugate addition of the allylcopper(I) reagent 182 or the lower order cyanocuprate 35, to the α,β-unsaturated aldehyde 71, were the key transformations to afford the aldehydes 239 and 80, respectively. Treatment of 239 or 80 with AModosuccinimide provided the alkenyl iodides 238 and 99 which underwent CrCl₂/NiCl₂-mediated cyclizations to provide the trans-fused bicyclo[3.3.0]octane and bicyclo[4.3.0]nonane systems, 237 and 102 & 103, respectively. These alcohols were converted into the corresponding ketones 236 and 83 in three additional steps. A copper(I) chloride-mediated intramolecular coupling reaction of alkenyltrimethylstannane moieties was used to provide highly substituted cyclopentene systems (273). Addition of 271, generated from 183 by treatment with methyllithium, to β-trimethylstannyl α,β-unsaturated aldehydes of general structure 275, followed by acetylation of the resultant alcohols provided 274. An intramolecular copper(I) chloride-mediated coupling of the alkenyltrimethylstannanes of general structure 274 gave the highly functionalized cyclopentenes of general structure 273. [Formula]

description: This thesis investigates the structural details of catalysis associated with the human enzyme, Glutathione Transferase Omega 1 (hGSTO1-1), a member of the most recently discovered class of Glutathione Transferase. The human genome contains two Omega class genes (hGSTO1 and 2) and their transcribed products have been found at varied levels within almost every tissue of the human body. The crystal structure of hGSTO1-1 displays a distinguishing cysteine residue in the active site, a feature that undoubtedly plays a role in the novel biochemistry it displays. Of most interest is the hGSTO1-1 mediated reduction of mono-and dimethylated arsenic species that result from human arsenic exposure. The enzyme is also essential for the enzymatic detoxification of alphahaloketones to acetophenones and exhibits a novel dehydroascorbate reductase activity. The following dissertation reports major progress in understanding the details of these chemical mechanisms. By observing these reactions within the crystallised enzyme using X-ray diffraction, several states within these catalytic cycles have been observed in great detail. Subsequently, hypotheses have been drawn about the product inhibition inferred during dehydroascorbate reduction, the existence of glutathione intermediates inherent to its interaction with methylated arsenicals, and the fundamental understanding of Omega mediated catalysis obtained by observing the enzymatic complex of oxidized glutathione and S-(4-Nitrophenacyl) glutathione simultaneously. In addition, adaptation of experimental conditions has led to the discovery of two new crystal forms with which to study the structural dynamics of this protein and its chemistry. The structure of a naturally occurring polymorphism involving the deletion of glutamate 155 has also been solved, revealing pronounced structural plasticity that correlates well with the apparent instability of the mutant enzyme in vivo. Discussions explore the broad implications for interpreting the role of hGSTO1-1 in the pathomechanisms of human disease states such as Alzheimer's disease and the biological mechanisms of arsenics' newly discovered potential as an anti-cancer agent.

description: We give a sufficient condition for the $kG$-Scott module with vertex $P$ to remain indecomposable under taking the Brauer construction for any subgroup $Q$ of $P$ as $k[Q\,C_G(Q)]$-module, where $k$ is a field of characteristic $2$, and $P$ is a wreathed $2$-subgroup of a finite group $G$. This generalizes results for the cases where $P$ is abelian and some others. The motivation of this paper is that the Brauer indecomposability of a $p$-permutation bimodule ($p$ is a prime) is one of the key steps in order to obtain a splendid stable equivalence of Morita type by making use of the gluing method that then can possibly lift to a splendid derived equivalence.

description: In order to attract volunteers after the end of the draft in 1973, the Army began an intensive advertising campaign aimed at young women.  In these ads the Army promoted itself as the ultimate equal opportunity employer -- something not always available in the civilian world.  However, these advertisements implied that the Army was just another employer competing for competent applicants.  What the ads failed to acknowledge is that the Army is not a job, but a culture, and a masculine one at that.  What was it like for these women to suddenly find themselves members of the biggest men's club in the world?  And would women find true equal opportunity in this man's Army?  In an effort to answer that question, the research contains oral history interviews conducted with women who served in the Army during 1973-1978 transition period.

description: We present the 12CO(1-0) and 13CO(2-1) line maps obtained observing with the SEST a $\sim 1\degr \times 1\degr$ region of the Vela Molecular Ridge, Cloud D. This cloud is part of an intermediate-mass star forming region that is relatively close to the Sun. Our observations reveal, over a wide range of spatial scales (from $\sim 0.1$ to a few parsecs), a variety of dense structures such as arcs, filaments and clumps, that are in many cases associated with far-IR point-like sources, recognized as young stellar objects and embedded star clusters. The velocity field analysis highlights the presence of possible expanding shells, extending over several parsecs, probably related to the star forming activity of the cloud. Furthermore, the analysis of the line shapes in the vicinity of the far-IR sources allowed the detection of 13 molecular outflows. Considering a hierarchical scenario for the gas structure, a cloud decomposition was obtained for both spectral lines by means of the CLUMPFIND algorithm. The CLUMPFIND output has been discussed critically and a method is proposed to reasonably correct the list of the identified clumps. We find that the corresponding mass spectrum shows a spectral index $α\sim1.3 ÷2.0$ and the derived clump masses are below the corresponding virial masses. The mass-radius and velocity dispersion-radius relationships are also briefly discussed for the recovered clump population.

description: Abstract

Eugenics or Perfect breeding theory gained prevalence in the later part of the twentieth century. Human beings have always strived for the perfect set of genes to be passed on from one generation to another. Eugenics is the highest form elimination of so-called wrong gene by ceasing particular race, caste, creed, religion or colour to form a relationship. Many of the physical and mental deformities are viewed as genetical and hence eugenics, though inhuman, is considered a way to gain social perfection. The most prominent issue with eugenics is that this high standard leads to misunderstanding between the couples thus resulting in dysfunctional Family. Through this research paper the researcher explores autism in one of the children as a reason for dysfunctional family and how in the name of societal norms parents and children belonging to autistic spectrum are relegated from the mainstream of the society to the fringes, thus causing unnecessary pressure in the family relationship and leading to unhappy married life and dysfunctional family. The researcher takes up three novels to understand the impact of children with autism in the family. They are The Curious incident of Dog in the Night time by Mark Haddon, Colin Fischer by Ashley Edward Miller and Zack Stentz and House Rules by Jodi Picoult. The focus of this research is to understand the impact of eugenics and the want for perfect gene in life leading to dysfunctional family when a child is born with autism.

description: How do galaxy properties (such as stellar mass, luminosity, star formation rate, and morphology) and their evolution depend on the mass of their host dark matter halo? Using the Galaxy and Mass Assembly (GAMA) group catalogue, we address this question by exploring the dependence on host halo mass of the luminosity function (LF) and stellar mass function (SMF) for grouped galaxies subdivided by colour, morphology and central/satellite. We find that spheroidal galaxies in particular dominate the bright and massive ends of the LF and SMF, respectively. More massive haloes host more massive and more luminous central galaxies. The satellite LF and SMF respectively show a systematic brightening of characteristic magnitude, and increase in characteristic mass, with increasing halo mass. In contrast to some previous results, the faint-end and low-mass slopes show little systematic dependence on halo mass. Semi-analytic models and simulations show similar or enhanced dependence of central mass and luminosity on halo mass. Faint and low-mass simulated satellite galaxies are remarkably independent of halo mass, but the most massive satellites are more common in more massive groups. In the first investigation of low-redshift LF and SMF evolution in group environments, we find that the red/blue ratio of galaxies in groups has increased since redshift $z \approx 0.3$ relative to the field population. This observation strongly suggests that quenching of star formation in galaxies as they are accreted into galaxy groups is a significant and ongoing process.

description: Internal states of polar molecules can be controlled by microwave-frequency electric dipole transitions. If the applied microwave electric field has a spatial gradient, these transitions also affect the motion of these dipolar particles. This capability can be used to engineer phonon-mediated quantum gates between e.g. trapped polar molecular ion qubits without laser illumination and without the need for cooling near the motional ground state. The result is a high-speed quantum processing toolbox for dipoles in thermal motion that combines the precision microwave control of solid-state qubits with the long coherence times of trapped ion qubits.

description: The dynamic response of ultracold Bose gases in one-dimensional optical lattices and superlattices is investigated based on exact numerical time evolutions in the framework of the Bose-Hubbard model. The system is excited by a temporal amplitude modulation of the lattice potential, as it was done in recent experiments. For regular lattice potentials, the dynamic signatures of the superfluid to Mott-insulator transition are studied and the position and the fine-structure of the resonances is explained by a linear response analysis. Using direct simulations and the perturbative analysis it is shown that in the presence of a two-colour superlattice the excitation spectrum changes significantly when going from the homogeneous Mott-insulator the quasi Bose-glass phase. A characteristic and experimentally accessible signature for the quasi Bose-glass is the appearance of low-lying resonances and a suppression of the dominant resonance of the Mott-insulator phase.

description: (Bi$_{1-x}$Sb$_x$)$_2$Te$_3$ topological insulators (TIs) are gathering increasing attention owing to their large charge-to-spin conversion efficiency and the ensuing spin-orbit torques (SOTs) that can be used to manipulate the magnetization of a ferromagnet (FM). The origin of the torques, however, remains elusive, while the implications of hybridized states and the strong material intermixing at the TI/FM interface are essentially unexplored. By combining interface chemical analysis and spin-transfer ferromagnetic resonance (ST-FMR) measurements, we demonstrate that intermixing plays a critical role in the generation of SOTs. By inserting a suitable normal metal spacer, material intermixing is reduced and the TI properties at the interface are largely improved, resulting in strong variations in the nature of the SOTs. A dramatic enhancement of a field-like torque, opposing and surpassing the Oersted-field torque, is observed, which can be attributed to the non-equilibrium spin density in Rashba-split surface bands and to the suppression of spin memory loss.

Liouville field theory with heavy charges. I. The pseudosphere
Creators: name: Menotti, Pietro

Year: 2006
Subjects: subject: High Energy Physics - Theory (hep-th)

description: We work out the perturbative expansion of quantum Liouville theory on the pseudosphere starting from the semiclassical limit of a background generated by heavy charges. By solving perturbatively the Riemann-Hilbert problem for the Poincare' accessory parameters, we give in closed form the exact Green function on the background generated by one finite charge. Such a Green function is used to compute the quantum determinants i.e. the one loop corrections to known semiclassical limits thus providing the resummation of infinite classes of standard perturbative graphs. The results obtained for the one point function are compared with the bootstrap formula while those for the two point function are compared with the existing double perturbative expansion and with a degenerate case, finding complete agreement.

description: The Salem witch trials were a tragedy that has partly defined a place for over 300 years. Since the crisis ended, interpretation of the trials has been wide and varied. In the 20th century, both the scholarship and tourism in Salem exploded, providing more opportunities than ever to interpret the effects the events had on both local and American identity.  However, the mythology that has erupted from the early scholarship, from the use of the trials as metaphor, and from the commercialization of a local event has complicated the way trial history is presented. By examining relevant public history literature, Salem trial historiography, and three specific area museums: the Salem Witch Museum, Witch Dungeon Museum, and Witch History Museum, this thesis will attempt to find ways to incorporate heritage and myth without complicating and distorting the history.

Predicting high rate granular transition and fragment statistics at the onset of granular flow for brittle ceramics

description: Brittle materials under impact loading exhibit a transition from a cracked solid to a granular medium. Appropriate representation of this transition to granular mechanics and the resulting initial fragment size and shape distribution in computational models is not well understood. The current work provides a numerical model to analyze competitive crack coalescence in the transition regime and provides insight into the onset of comminution and the initial conditions for subsequent granular flow. Crack statistics obtained from initial flaws using a wing crack growth based damage model have been used to discretely model elliptical cracks in three dimensions, with and without a minimal intersection constraint. These cracks are then allowed to coalesce with nearby cracks along favourable directions and the output fragment statistics have been predicted. The evolving fragmentation offers insight into the onset of comminution as well as the final transition to granular mechanics and the resulting initial fragment statistics. A simple phenomenological model has been proposed that suggests a transition criterion resembling the one obtained from the numerical model.

Voiceless: The Restriction of the Russian Press and the Rise of Chechen Violence, 2002-2004
Creators: name: Meyer, Misty
Publisher: name: Maryland Shared Open Access Repository
Year: 2008
Subjects: History, Modern (0582)

description: Since the beginning of the second Chechen war in 1999 and the onset of the Putin government in Russia, the freedom given to the Russian press has declined. At the same time, Chechen violence targeting the Russian military and civilians and the popularity of Vladimir Putin has increased. The two events are connected. The press gave the Chechen rebels a means, albeit one-sided, to communicate with the Russian people. Restrictions on the press limited the Chechen's ability to convey their plight, at the hands of the Russian military, to the Russian populace. The Chechen reaction was increased violence to gain the attention of the Russian people. Vladimir Putin used the restrictions on the press to create the sense of a strong government. Without reports focusing on the atrocities in Chechnya, the Russians were left with a faceless, voiceless monster that only the Putin government could seemingly defeat. This thesis tracks this trend through the evolution of Chechen terror acts in Moscow, beginning with large-scale hostage taking events in Dubrovka during the fall of 2002, when the press presented both sides. This thesis ends with the large-scale hostage taking event in Beslan in 2004, when the press was largely silent on the motivations of the hostage takers. These acts impress a feeling of terror on the Russian nation, but the reporting gives nothing in the way of explanation. The resolution of these acts gives a sense of security to the Russian populace at the hands of Vladimir Putin.
