description: The observation of charged lepton flavor non-conservation would be a clear signature of physics beyond the Standard Model. In particular, supersymmetric (SUSY) models introduce mixings in the sneutrino and the charged slepton sectors which could imply flavor-changing processes at rates accessible to upcoming experiments. In this paper we analyze the possibility to observe Z --> lep_I lep_J in the GigaZ option of TESLA at DESY. We show that although models with SUSY masses above the current limits could predict a branching ratio BR(Z --> mu e) accessible to the experiment, they would imply an unobserved rate of mu --> e gamma and thus are excluded. In models with a small mixing angle between the first and the third (or the second and the third) slepton families GigaZ could observe Z --> tau mu (or Z --> tau e) consistently with present bounds on lep_J --> lep_I gamma. In contrast, if the mixing angles between the three slepton families are large the bounds from mu --> e gamma push these processes below the reach of GigaZ. We show that in this case the masses of the three slepton families must be strongly degenerated (with mass differences of order 10^{-3}). We update the limits on the slepton mass insertions delta_{LL,RR,LR} and discuss the correlation between flavor changing and g_mu-2 in SUSY models.

description: Following the 1994 Genocide, Rwanda embarked on an ambitious plan to resettle its entire rural population into thousands of planned settlements across the country.  Development agencies at the time were skeptical of such a plan as similar efforts across Africa had largely failed and were crippled by corruption, human rights abuses and poor follow through.  Rwanda however, has been an exception.  Twenty years after the initial Human Settlement Policy was introduced, Rwanda has made notable strides towards addressing land use planning, a poor education record, high levels of poverty and low levels of health access.  Through national-level strategies, clear and concise goals, adequate international and domestic funding, and an acute recognition of its vulnerable populations, Rwanda is now leading Africa in economic, health, education, and environmental standards.  This thesis explores Rwanda's resettlement practices and argues that it could not have been realized without thoughtful and decisive actions taken by the Government in planning and executing the rural resettlement program.

The Labor of the Avant-Garde: Experimental Form and the Politics of Work in Post-War American Poetry and Fiction

description: While literary critics have explored the politics of labor in pre-war modernist
      literature, the post-45 avant-garde has continued to be framed as a depoliticized repetition of previous avant-garde styles. Examining American avant-garde literature in its relation to the political and economic shifts from the 1960s through the late 1980s, my
      dissertation corrects this narrative to show that labor and labor politics were central
      categories in post-war experimental poetry and fiction. I argue that writers as disparate as Charles Olson, William S. Burroughs, Samuel R. Delany, and Susan Howe reworked
      disjunctive modernist forms to cognitively map emergent economic tendencies in the US.
      Parataxis, collage, surrealist imagery, aleatory compositional methods, non-linear
      plotting, and metafictional narrative conceits all constitute the stylistic techniques of an
      avant-garde engaged in an extended dialogue about work and the politics of work. The
      canon of experimental literature functioned as a counter-discourse that contested and
      reshaped discourses of labor by considering it alongside categories of race, gender, and
      sexuality.
      By using labor as an entry point into the avant-garde, my dissertation reconsiders
      the post-war literary canon, revealing an avant-garde that includes writers working across modes and genres. The adaptation of experimental techniques in genre writing turned the avant-garde into a popular literary mode. My dissertation particularly focuses on science fiction (SF), where the adaptation of experimental style played a crucial role in the development of the genre. Beginning with the 1960s British and American New Wave movement, SF writers turned to the experimental novel--often by way of modernist
      poetics--as a way to challenge the reified form of mainstream science fiction novels. I
      argue that this critique of the novel also functioned as a covert critique of the labor
      practices of the literary market place that guided the production of genre fiction. In this
      way, I contest traditional accounts that see post-war and contemporary experimental
      literature as increasingly marginal and self-reflective by tracking the avant-garde's
      concern with depicting quotidian work, and representing themselves as workers, to
      critique institutions of intellectual and artistic production.
From inflation to a zero cosmological constant phase without fine tuning

description: We show that it is possible to obtain inflation and also solve the cosmological constant problem. The theory is invariant under changes of the Lagrangian density $L$ to $L+const$. Then the constant part of a scalar field potential $V$ cannot be responsible for inflation. However, we show that inflation can be driven by a condensate of a four index field strength. A constraint appears which correlates this condensate to $V$. After a conformal transformation, the equations are the standard GR equations with an effective scalar field potential $V_{eff}$ which has generally an absolute minimum $V_{eff}=0$ independently of $V$ and without fine tuning. We also show that, after inflation, the usual reheating phase scenario (from oscillations around the absolute minimum) is possible.

Benchmarking Heat Across Campbelltown City, New South Wales
Creators: name: Pfautsch, Sebastian

Publisher: name: Western Sydney University
Year: 2019

description: The compounding effects of climate change and rapid urbanisation cause cities to heat up. Metropolitan Sydney is no exception to this trend. Today, the communities of Campbelltown City in the southern region of the Greater Sydney Basin already experience extreme summer temperatures and heatwave conditions on an annual basis. Climate predictions point toward amplification of summer heat. Already today these conditions represent a serious threat to the quality of life, public health and economic prosperity in the region. Near-surface air temperature in complex urban terrain can vary. A large proportion of this variation originates from differences in thermal characteristics of materials that together make up the terrain. While roads and buildings can lead to higher temperatures in urban landscapes, trees and other green urban infrastructure can provide cooling. Hence, depending on the kind, make and proportion of urban infrastructure types (e.g. grey, green, blue), air temperatures will vary. Until now, the magnitude of air temperature variation among suburbs within the Campbelltown City Local Government Area (LGA) remained unknown.

description: Career centers in higher education must create environments that serve the needs of students and alumni. Alumni not only are a served population, but also are beneficial to student career development, and serve dual purposes as clients and volunteers. One program frequently offered by career centers that engages alumni volunteers is an alumni mock interview program. While the alumni volunteers act as interviewers to share their insights and professional experience, they too are clients, so their learning must be considered. Existing mock interview program research primarily examines the student learning experience. This study addressed the research problem of the unknown learning experience of alumni mock interviewers. The purpose was to explore with a group of alumni volunteers their perceptions of their learning experience as interviewers within a mock interview program. To achieve this purpose, the researcher employed a qualitative, single-case study approach drawing upon the experiences of alumni mock interviewers within a particular setting. Data was collected from 43 participants providing questionnaire ratings and 25 subset participants completing critical incident written responses and interviews. Four major study findings emerged: (1) All described what they learned, with a majority learning the importance of creating a comfortable environment, delivering feedback, offering the program for students’ preparation, and understanding current students’ experiences; (2) All found aspects that contributed to their learning, with a majority describing having sample interview questions and staying in touch with students as helpful; (3) All found aspects that inhibited their learning, with a majority describing the lack of connection with fellow alumni mock interviewers and lack of industry knowledge of specific fields as hindering; (4) All described program design recommendations to foster alumni learning, with a majority recommending matching students with alumni based on industry and background, providing an opportunity to hear about alumni experiences, and offering advanced training to students. The principal recommendations of the study have implications for higher education career service professionals on how to design mock interview programs to engage alumni in lifelong learning by considering the sources of knowledge within the program and utilizing adult learning theory and learning from experience frameworks as guides.

The temperature profile with respect to proper time determined in that context exhibits no differences with the ideal fluid. On the contrary, it is shown that the profile obtained when Müller-Israel-Stewart second order theory of dissipation is included on top of standard hydrodynamics indicates a slower cooling of the system.

description: The adiabatic charge pumping of a non-equilibrium state of spinless fermions in a one-dimensional lattice is investigated, with an emphasis placed on its usefulness in revealing many-body interaction effects on interband coherence. For a non-interacting system, the pumped charge per adiabatic cycle depends not only on the topology of the occupied bands but also on the interband coherence in the initial state. This insight leads to an interesting opportunity for quantitatively observing how quantum coherence is affected by many-body interaction that is switched on for a varying duration prior to adiabatic pumping. In particular, interband coherence effects can be clearly observed by adjusting the switch-on rates with different adiabatic pumping protocols and by scanning the duration of many-body interaction prior to adiabatic pumping. The time dependence of single-particle interband coherence in the presence of many-body interaction can then be examined in detail. As a side but interesting result, for relatively weak interaction strength, it is found that the difference in the pumped charges between different pumping protocols vanishes if a coherence measure defined from the single-particle density matrix in the sublattice representation reaches its local minima. Our results hence provide an interesting means to quantitatively probe the dynamics of quantum coherence in the presence of many-body interaction (e.g., in a thermalization process).

description: Although knowing the occurrence frequency of severe space weather events is important for a modern society, it is insufficiently known due to the lack of magnetic or sunspot observations, before the Carrington event in 1859 known as one of the largest events during the last two centuries. Here, we show that a severe magnetic storm occurred on 8 March 1582 based on auroral records in East Asia. The equatorward boundary of auroral visibility reached 28.8° magnetic latitude. The equatorward boundary of the auroral oval is estimated to be 33.0° invariant latitude (ILAT), which is comparable to the storms on 25/26 September 1909 (~31.6° ILAT, minimum Dst of -595 nT), 28/29 August 1859 (~36.5° ILAT), and 13/14 March 1989 (~40° ILAT, minimum Dst of -589 nT). Assuming that the equatorward boundary is a proxy for the scale of magnetic storms, we presume that the storm on March 1582 was severe. We also found that the storm on March 1582 lasted, at least, for three days by combining European records. The auroral oval stayed at mid-latitude for the first two days and moved to low-latitude (in East Asia) for the last day. It is plausible that the storm was caused by a series of ICMEs (interplanetary coronal mass ejections). We can reasonably speculate that a first ICME could have cleaned up interplanetary space to make the following ICMEs more geo-effective, as probably occurred in the Carrington and Halloween storms.

The Lebanese Legal System’s Contribution to Child Marriage

description: Efforts to eradicate issues of women’s rights and gender-based violence, especially child marriage, have for years been concealed because of their sensitive links to religious and cultural ideals. Research has shown that those most affected by such forms of violence are the most vulnerable and often in a state of migration. Lebanon, today, hosts more than two million refugees of Syrian and Palestinian descent with little to no preparations on their housing and living requirements. Consequently, rates of law violations especially against women and minors are clearly evident within these populations. Recent data has shown that the rates of child marriage among the Syrian community across Lebanon are alarming with a common belief that this is a practice only in occurrence among the migrating population. Nevertheless, the legal system in Lebanon does in fact allow child marriage and remains very reluctant for passing amendments regarding this issue. The recent prominence of child marriage in Lebanon has opened the eyes of the civil society to take a stance and advocate against the independent personal status system in the country. Little scholarly research has been done to demonstrate where and how the legal system falls short in addressing such a critical matter. This paper aims to close the gap in the existing academic literature on the personal status system in Lebanon and women’s rights. Furthermore, efforts of the international community on children’s rights, particularly early marriage are recorded in this thesis along with Lebanon’s unwillingness to properly execute new measures granting women and children their deserved rights. To investigate these issues, this study applies a human rights framework to the following research question: How does the Lebanese legal system allow for child marriage, particularly among refugees?

description: A living cell senses its environment and responds to external signals. In this work, we study theoretically, the precision at which cells can determine the position of a spatially localized transient extracellular signal. To this end, we focus on the case, where the stimulus is converted into the release of a small molecule that acts as a second messenger, for example, Ca$^{2+}$, and activates kinases that change the activity of enzymes by phosphorylating them. We analyze the spatial distribution of phosphorylation events using stochastic simulations as well as a mean-field approach. Kinases that need to bind to the cell membrane for getting activated provide more accurate estimates than cytosolic kinases. Our results could explain why the rate of Ca$^{2+}$ detachment from the membrane-binding conventional Protein Kinase C$α$ is larger than its phosphorylation rate.
Distribution of Values of Real Quadratic Zeta Functions

description: The author has previously extended the theory of regular and irregular primes to the setting of arbitrary totally real number fields. It has been conjectured that the Bernoulli numbers, or alternatively the values of the Riemann zeta function at odd negative integers, are evenly distributed modulo p for every p. This is the basis of a well-known heuristic, given by Siegel, for estimating the frequency of irregular primes. So far, analyses have shown that if Q(\sqrt{D}) is a real quadratic field, then the values of the zeta function ζ_{D}(1-2m)=ζ_{Q(\sqrt{D})}(1-2m) at negative odd integers are also distributed as expected modulo p for any p. However, it has proven to be very computationally intensive to calculate these numbers for large values of m. In this paper, we present the alternative of computing ζ_{D}(1-2m) for a fixed value of D and a large number of different m.

description: Sunspot observations in chromospheric spectral lines have revealed the existence of short-lived linear bright transients, commonly referred to as penumbral micro-jets (PMJs). Details on the origin and physical nature of PMJs are to large extend still unkown. We aim to characterize the dynamical nature of PMJs to provide guidance for future modelling efforts. We analyze high spatial (0.1 arcsec) and temporal resolution (1 s) Ca II H filtergram (0.1 nm bandwidth) observations of a sunspot obtained on two consecutive days with the Swedish 1-m Solar Telescope. We find that PMJs appear to be the rapid brightening of an already existing (faint) fibril. The rapid brightening is the fast increase (typically less than 10 s) in intensity over significant length (several 100s of km) of the existing fibril. For most PMJs, we cannot identify a clear root or source from where the brightening appears to originate. After the fast onset, about half of the PMJs have a top that is moving with an apparent velocity between 5 and 14 km/s, most of them upwards. For the other PMJs, there is no significant motion of the top. For about a third of the PMJs we observe a splitting into two parallel and co-evolving linear features during the later phases of the lifetime of the PMJ. We conclude that mass flows can play only limited role in the onset phase of PMJs and that it is more likely that we see the effect of a fast heating front.

description: The stochastic volatility model is a popular tool for modeling the volatility of assets. The model is a nonlinear and non-Gaussian state space model, and consequently is difficult to fit. Many approaches, both classical and Bayesian, have been developed that rely on numerically intensive techniques such as quasi-maximum likelihood estimation and Markov chain Monte Carlo (MCMC). Convergence and mixing problems still plague MCMC algorithms when drawing samples sequentially from the posterior distributions. While particle Gibbs methods have been successful when applied to nonlinear or non-Gaussian state space models in general, slow convergence still haunts the technique when applied specifically to stochastic volatility models. We present an approach that couples particle Gibbs with ancestral sampling and joint parameter sampling that ameliorates the slow convergence and mixing problems when fitting both univariate and multivariate stochastic volatility models. We demonstrate the enhanced method on various numerical examples.

description: The exact form of the Jacobi -- Levi-Civita (JLC) equation for geodesic spread is here explicitly worked out at arbitrary dimension for the configuration space manifold M_E = {q in R^N | V(q) < E} of a standard Hamiltonian system, equipped with the Jacobi (or kinetic energy) metric g_J. As the Hamiltonian flow corresponds to a geodesic flow on (M_E,g_J), the JLC equation can be used to study the degree of instability of the Hamiltonian flow. It is found that the solutions of the JLC equation are closely resembling the solutions of the standard tangent dynamics equation which is used to compute Lyapunov exponents. Therefore the instability exponents obtained through the JLC equation are in perfect quantitative agreement with usual Lyapunov exponents. This work completes a previous investigation that was limited only to two-degrees of freedom systems.

description: Seed dormancy determines germination timing, influencing seed plant adaptation and overall fitness. DELAY OF GERMINATION 1 (DOG1) is a conserved central regulator of dormancy cooperating with the phytohormone abscisic acid (ABA) through negative regulation of ABA HYPERSENSITIVE GERMINATION (AHG) 1 and AHG3 phosphatases. The current molecular mechanism of DOG1 signaling proposes it regulates the activation of central ABA-related SnRK2 kinases. Here, we unveil DOG1's functional autonomy from the regulation of ABA core signaling components and unravel its pivotal control over the activation of ABSCISIC ACID INSENSITIVE FIVE BINDING PROTEINs (AFPs). Our data revealed a molecular relay in which AFPs' genuine activation by AHG1 is contained by DOG1 to prevent the breakdown of maturation-imposed ABA responses independently of ABA-related kinase activation status. This work offers a molecular understanding of how plants fine-tune germination timing, while preserving seed responsiveness to adverse environmental cues, and thus represents a milestone in the realm of conservation and breeding programs.

We propose a pump-probe scheme in Si-based waveguide where a strong continuous wave (CW) pump excites free carriers that leads to a linear potential through a time dependent refractive index change which is experienced by the finite energy Airy pulse (FEAP) (probe). The linear potential significantly manipulate the dynamics of a FEAP and leads to a monotonous spectral shift. We mathematically model the dynamics of the Airy pulse using linear dispersion equation containing an optical potential term and establish the general solution of the pulse for non-vanishing third order dispersion (TOD). We derive the expression of the trajectory of FEAP which deviates significantly from its usual ballistic nature and can be tailored with the strength of the linear potential. For positive TOD, the propagating Airy pulse experiences a singularity and flips in time domain. We theoretically derive that for a specific potential strength the flipping region is squeezed to a point and revives thereafter. We propose an exact analytical solution beyond flipping region for this specific case. Our theoretical analysis corroborates well with the numerical results. The present study may be useful in applications related to pulse reshaping and trajectory manipulation

description: In radio interferometry, every pair of antennas in an array defines one sampling point in the Fourier domain of the sky image. By combining information from different wavelengths, sample coverage - and therefore reconstruction quality - can be increased. However, the images at different wavelengths can be dramatically dissimilar; this fact must be taken into account when reconstructing multi-frequency images. In this paper, we present a novel reconstruction algorithm based on the assumption that the spectrum is continuous. In contrast to prior work, we allow for sparse deviations from this assumption: this allows, for example, for accurate reconstruction of line spectra superimposed on a continuum. Using simulated measurements on synthetic multi-frequency images, we show that the proposed approach provides significant improvements over a comparable method based solely on a continuity assumption.

Subjects: subject: General Relativity and Quantum Cosmology (gr-qc)

description: The geodesic deviation equation (`GDE') provides an elegant tool to investigate the timelike, null and spacelike structure of spacetime geometries. Here we employ the GDE to review these structures within the Friedmann--Lema\^ıtre--Robertson--Walker (`FLRW') models, where we assume the sources to be given by a non-interacting mixture of incoherent matter and radiation, and we also take a non-zero cosmological constant into account. For each causal case we present examples of solutions to the GDE and we discuss the interpretation of the related first integrals. The de Sitter spacetime geometry is treated separately.

The Levantine Maqāma Before the Nahḍa and Beyond the Novel

Subjects: Middle Eastern literature
History
Arabic literature

description: This dissertation is a study of Arabic narrative forms and writing practices on the cusp of modernity. It is set in and around the Ottoman provinces of Mount Lebanon, and spans the period from the late-eighteenth century to the mid-nineteenth century. Through the study of four maqāma collections composed between the 1770s and 1856, this project offers a microhistory of a literary form before and during its earliest encounter with the Nahḍa, or Arab renaissance in the mid-nineteenth century. These highly self-reflexive maqāma collections not only shed light on practices of textuality prior to the spread of print journals and the “new” reading public in the mid-nineteenth century, but also provide an empirical basis for furthering the critique of the centrality of the novel to the definition and periodization of Arabic literary modernity. In its broadest ambition, however, this project is a search for a new theoretical language to describe this maqāma corpus and, through it, key facets of the genre in the modern period.
Limit of torsion semi-stable Galois representations with unbounded weights

description: Let $K$ be a complete discrete valuation field of characteristic $(0, p)$ with perfect residue field, and let $T$ be an integral $\mathbb{Z}_p$-representation of $\mathrm{Gal}(\overline{K}/K)$. A theorem of T. Liu says that if $T/p^n T$ is torsion semi-stable (resp. crystalline) of uniformly bounded Hodge-Tate weights for all $n \geq 1$, then $T$ is also semi-stable (resp. crystalline). In this note, we show that we can relax the condition of "uniformly bounded Hodge-Tate weights" to an unbounded (log-)growth condition.

The Life and Death of Mass Media

description: There is a paradox in our understanding of the media today. Popular accounts often proclaim that mass media is dead while newspapers routinely report that new Hollywood box-office records have been smashed. In this dissertation I aim to resolve this paradox and to determine whether or not mass media is in fact in terminal decline. I propose two new concepts - the principle of cheap publicity and the mass media tendency - and I use a computer simulation to demonstrate that these provide a parsimonious explanation of the paradoxical structure of today's dominant media. This leads me to the conclusion that mass media is not in terminal decline; rather, there has been a shift in the social locus of mass media. Throughout most of the American 20th century, massification played a central role in the guiding logic of media firms. Beginning in the 1970s though, these firms began adopting strategies of audience segmentation. In the decades since this rupture mass media has lived on as the emergent outcome of audience behavior rather than as an innate characteristic of media technologies or institutions. I discuss the implications of this finding for the structure of the contemporary American public sphere and for the experience of publicity today.

CP-odd A^0 production at e^+e^- colliders in MSSM with CP violating phases

description: We study the production of a heavy CP-odd $A^0$ boson in association with a photon $e^+e^-\to A^0γ$ and a Z boson $e^+e^-\to A^0 Z$ as well as the single production of $A^0$ via $e^+e^- \to ν_e\barν_e A^0$ in the MSSM with CP violating phases. In the case of $e^+e^-\to A^0γ/ A^0 Z$, we show that the squark contribution, which vanishes in the MSSM with real parameters, turns out to be sizeable in presence of CP violating phases in the soft SUSY parameters. For $e^+e^- \to ν_e \barν_e A^0$ in both the 2HDM and MSSM with real parameters, the cross section does not reach observable rates at a NLC. It is found that with a large CP violating phase for $A_t$, cross sections of the order 0.1 fb are attainable for all the processes $e^+e^-\to A^0γ$, $e^+e^-\to A^0 Z$ and $e^+e^- \to ν_e \barν_e A^0$.

description: Over 250,000 farmers have committed suicide across India since 1995, the majority of deaths concentrated in central India’s cotton belt. Scholarly consensus views suicides amongst the peasantry as debt-induced: transgenic cotton cultivation imprisons producers in downward monetary debt spirals. Based on two years of fieldwork in rural Vidarbha, my dissertation, ‘The Life of Debt in Rural India,’ examines the proximate entanglements of debt and techno-material transformations in cotton cultivation. It demonstrates that with the emergence of cash-debt as an essential component of the productive process, differentiated interest rates have become the medium of negotiating social and familial proximity. From a formerly caste-specific proscribed activity, the generalization of usurious lending has made monetary debt the language of social prestations (of gifts, grain and labour), reshaping customary understandings of status, honour and obligation. This project contributes to the anthropology of South-Asia, the peasantry and debt in two ways. In ethnographically tracing the force of debt as social obligation and the imbrication of modes of production with symbolic cultural life, I demonstrate the inadequacy of an economistic obsession with debt as monetary liability. Accordingly, against characterizations of the ‘risk-averse’ peasant in a customary moral economy, I describe an emergent ethical economy centered on uncertainty as risk becomes a structural precondition of peasant life.

description: A high theoretical efficiency of 47.2% was achieved by a novel combination of In0.51Ga0.49P, GaAs, In0.24Ga0.76As and In0.19Ga0.81Sb subcell layers in a simulated quadruple junction solar cell under 1 sun concentration. The electronic bandgap of these materials are 1.9 eV, 1.42 eV, 1.08 eV and 0.55 eV respectively. This unique arrangement enables the cell absorb photons from ultraviolet to deep infrared wavelengths of the sunlight. Emitter and base thicknesses of the subcells and doping levels of the materials were optimized to maintain the same current in all the four junctions and to obtain the highest conversion efficiency. The short-circuit current density, open circuit voltage and fill factor of the solar cell are 14.7 mA/cm2, 3.38 V and 0.96 respectively. In our design, we considered 1 sun, AM 1.5 global solar spectrum.
