description: SLMAP is a tail anchored membrane protein that alternatively splices to generate three isoforms, SLMAP1, SLMAP2 and SLMAP3. Previous studies in our lab have shown that the postnatal cardiac-specific overexpression of SLMAP1 results in intracellular vesicle expansion and enhanced endosomal recycling. I generated a postnatal cardiac-specific knockout model using the Cre-Lox system to nullify all three SLMAP isoforms and further evaluate its role in the mouse myocardium. SLMAP knockdown and knockout mouse hearts were analyzed with western blotting and qPCR. I found that only SLMAP3 was nullified and phenotypic evaluation through echocardiography indicated that young and old SLMAP3 knockout animals showed no remarkable changes in cardiac function. Furthermore, challenge with stressor isoproterenol had a similar response to wildtype and knockout mice in cardiac structure and function. Surprisingly the level of expression of SLMAP1 and SLMAP2 was maintained in the myocardium from SLMAP3 deficient mice. Interestingly the machinery involved in endosomal recycling was not impacted by the loss of SLMAP3. These data indicate that loss of SLMAP3 does not alter cardiac structure and function in the postnatal myocardium in the presence of SLMAP1 and SLMAP2.

description: We have studied the edge spin accumulation in a high mobility two-dimensional electron gas formed in a symmetric well with two subbands. This study is strongly motivated by the recent experiment of Hernandez et al. [Phys. Rev. B {\bf 88}, 161305(R) (2013)] who demonstrated the spin accumulation near the edges of a bilayer symmetric GaAs structure in contrast to no effect in a single-layer configuration. The intrinsic mechanism of the spin-orbit interaction we consider arises from the coupling between two subband states of opposite parities. We obtain a parametrically large magnitude of the edge spin density for the two-subband sample as compared to the usual single-subband structure. We show that the presence of a gap in the system, i.e., the energy separation $Δ$ between the two subband bottoms, changes drastically the picture of the edge spin accumulation. Thus one can easily proceed from the regime of weak spin accumulation to the regime of strong one by varying the Fermi energy (electron density) and/or $Δ$. We estimate that by changing the gap $Δ$ from zero up to $1÷2$ K, the magnitude of the effect changes by three orders of magnitude. This opens up the possibility for the design of new spintronic devices.

description: The Sociolinguistic Attitudes of Kazakhs Towards the Latin Alphabet and Orthography Reform in Kazakh
      (Under the direction of David Mora-Marin)
      This research study examines the sociolinguistic attitudes of Kazakhs towards the Latin alphabet and orthography reform by means of the sociolinguistic attitude survey. The recent announcement of Nursultan Nazarbaev, the Kazakh president of the Republic of Kazakhstan, about an intention of the Kazakh government to have shifted the current Cyrillic-based Kazakh alphabet to the Latin seemed to lead to the division of the Kazakh society into two opposite groups. The president announced a full support of the Latin alphabet adoption by various sections of the population of Kazakhstan, although there is not or no publicly available a research study or official consensus regarding the reform in Kazakh. Therefore, this research study is directly motivated by this linguistic situation in Kazakhstan. To find out whether such an alphabet and orthography reform is triggered by a linguistic need of Kazakh, an interview with some Kazakh language experts was also conducted in addition to the sociolinguistic survey. As a result, both the Kazakh language users and experts unanimously support the current reform and associate it with a language need and globalization.

description: Johnny Drops the Bomb is a site-specific, historical play written to be performed in the Diefenbunker, a bomb shelter built to protect key members of the Canadian government in the event of a nuclear attack. As a practice-as-research project, Johnny Drops the Bomb explores the theories and techniques associated with performing history in situ: aura and atmosphere, empathy and witnessing, embodiment and being-in-the-world, proximity and site-specificity, and upsurges of the Real. As the written component of that practical project, this thesis contextualizes Johnny Drops the Bomb by situating it within these approaches, reflecting on the role that each technique played as I wrote, rehearsed, and ultimately performed it with two other actors.

description: We present a comprehensive and versatile theoretical framework to study site and bond percolation on clustered and correlated random graphs. Our contribution can be summarized in three main points. (i) We introduce a set of iterative equations that solve the exact distribution of the size and composition of components in finite size quenched or random multitype graphs. (ii) We define a very general random graph ensemble that encompasses most of the models published to this day, and also that permits to model structural properties not yet included in a theoretical framework. Site and bond percolation on this ensemble is solved exactly in the infinite size limit using probability generating functions [i.e., the percolation threshold, the size and the composition of the giant (extensive) and small components]. Several examples and applications are also provided. (iii) Our approach can be adapted to model interdependent graphs---whose most striking feature is the emergence of an extensive component via a discontinuous phase transition---in an equally general fashion. We show how a graph can successively undergo a continuous then a discontinuous phase transition, and preliminary results suggest that clustering increases the amplitude of the discontinuity at the transition.

description: We present the EXPLORE Horizon 2020 Research & Innovation project and its first outcomes. EXPLORE's main objective is to develop and deploy a suite of scientific data applications (SDAs) to foster exploitation of scientific data from astrophysics and planetary space missions. Six SDAs will produce new scientific data products and offer new scientific services. Four of the applications will leverage data primarily from Gaia, developing tools to help understand the evolution of our galaxy, the 3D distribution of interstellar matter, and support the discovery, classification, and characterisation of stars. The other two applications will integrate data from a range of lunar missions to focus on characterisation of the Moon's surface and potential human landing sites. The SDAs will utilise state-of-the-art Artificial Intelligence and visual analytics to enhance science return and discovery. In parallel, we built a small virtual platform (explore-platform.eu) that is used to develop, validate, and test each SDA. Later it could be offered as a service. The SDAs will be deployed, under open-source licences, on different cloud science platforms (e.g., ESA Datalabs and ESCAPE Science Analysis Platform) to stimulate uptake and sustainability. This open science project will help democratise space science exploration and exploitation. This project has received funding from the European Union's Horizon 2020 research and innovation pro-gramme under grant agreement No 101004214.

description: Water saving devices in the sanitary equipment, such as flow regulators, are assumed to be environmentally advantageous even though their environmental benefit has never been compared to the environmental burden caused during their production und disposal. Therefore, a life cycle assessment according to ISO 14044 has been conducted to identify and quantify the environmental effects throughout the lifespan of a flow regulator. The analysis comprises the production of materials, manufacturing of components at suppliers, the assembly at NEOPERL®, all transports, savings of water and thermal energy during use as well as waste incineration including energy recovery in the end-of-life stage. Results show that the production of one flow regulator causes 0.12 MJ primary energy demand, a global warming potential of 5.9 g CO2-equivalent, and a water consumption of 30.3 ml. On the other hand, during a use of 10 years, it saves 19,231 MJ primary energy, 1223 kg CO2-equivalent, and avoids a water consumption of 790 l (166,200 l water use). Since local impacts of water consumption are more relevant than volumes, consequences of water consumption have been analyzed using recently developed impact assessment models. Accordingly, the production of a flow regulator causes 8.5 ml freshwater depletion, 1.4 × 10−13 disability adjusted life years, and 4.8 × 10−6 potentially disappeared fractions of species m2 a. Even though avoided environmental impacts resulting from water savings highly depend on the region where the flow regulator is used, the analysis has shown that environmental benefits are at least 15,000 times higher than impacts caused during the production.
How unsplittable-flow-covering helps scheduling with job-dependent cost functions

description: Generalizing many well-known and natural scheduling problems, scheduling with job-specific cost functions has gained a lot of attention recently. In this setting, each job incurs a cost depending on its completion time, given by a private cost function, and one seeks to schedule the jobs to minimize the total sum of these costs. The framework captures many important scheduling objectives such as weighted flow time or weighted tardiness. Still, the general case as well as the mentioned special cases are far from being very well understood yet, even for only one machine. Aiming for better general understanding of this problem, in this paper we focus on the case of uniform job release dates on one machine for which the state of the art is a 4-approximation algorithm. This is true even for a special case that is equivalent to the covering version of the well-studied and prominent unsplittable flow on a path problem, which is interesting in its own right. For that covering problem, we present a quasi-polynomial time (1+ε)-approximation algorithm that yields an(e+ε)-approximation for the above scheduling problem. Moreover, for the latter we devise the best possible resource augmentation result regarding speed: a polynomial time algorithm which computes a solution withoptimalcost at1+εspeedup. Finally, we present an elegant QPTAS for the special case where the cost functions of the jobs fall into at mostlognmany classes. This algorithm allows the jobs even to have up tolognmany distinct release dates. All proposed quasi-polynomial time algorithms require the input data to be quasi-polynomially bounded.
Understanding Greek Equestrian Imagery in the Archaic Through Hellenistic Periods
Creators: name: Phebus, Angelina Danielle
Publisher: name: University of North Carolina at Chapel Hill
Year: 2013

description: This study analyzes equestrian imagery from the Archaic through Hellenistic periods in Greece. I investigate why horse depictions were employed in the contexts of votive offerings, funerary sculpture, and architectural sculpture. I consider whether horses' renderings can be related to socio-political phenomena respective of their physical and historical context by looking at horses in terms of type, conformation, and scale. While athletic monuments, represented by the Delphi charioteer and the Artemision Horse and Jockey in this project, promote individualism of aristocratic victors through portrait-like depictions of competition horses, Classical reliefs are idealized. Prinias A, the Siphnian Treasury, the Parthenon frieze, and Classical Athenian funerary reliefs show the development of the composite type. The Horse and Groom Relief demonstrates the return to individualized depictions of horses on funerary monuments in the early Hellenistic period.

description: We investigate a geometric computational framework, called the "scaling-rotation framework", on ${\rm Sym}^+(p)$, the set of $p \times p$ symmetric positive-definite (SPD) matrices. The purpose of our study is to lay geometric foundations for statistical analysis of SPD matrices, in situations in which eigenstructure is of fundamental importance, for example diffusion-tensor imaging (DTI). Eigen-decomposition, upon which the scaling-rotation framework is based, determines both a stratification of ${\rm Sym}^+(p)$, defined by eigenvalue multiplicities, and fibers of the "eigen-composition" map $SO(p)\times{\rm Diag}^+(p)\to{\rm Sym}^+(p)$. This leads to the notion of scaling-rotation distance [Jung et al. (2015)], a measure of the minimal amount of scaling and rotation needed to transform an SPD matrix, $X,$ into another, $Y,$ by a smooth curve in ${\rm Sym}^+(p)$. Our main goal in this paper is the systematic characterization and analysis of minimal smooth scaling-rotation (MSSR) curves, images in ${\rm Sym}^+(p)$ of minimal-length geodesics connecting two fibers in the "upstairs" space $SO(p)\times{\rm Diag}^+(p)$. The length of such a geodesic connecting the fibers over $X$ and $Y$ is what we define to be the scaling-rotation distance from $X$ to $Y.$ For the important low-dimensional case $p = 3$ (the home of DTI), we find new explicit formulas for MSSR curves and for the scaling-rotation distance, and identify ${\cal M}(X,Y)$ in all "nontrivial" cases. The quaternionic representation of $SO(3)$ is used in these computations. We also provide closed-form expressions for scaling-rotation distance and MSSR curves for the case $p = 2$.

Bias Crime Statutes: A Qualified Liberal Defense

Publisher: name: The University of North Carolina at Chapel Hill University Libraries
Year: 2010

description: Since American legislatures began passing bias crime statutes (which set more severe penalties for crimes committed from biased motives) in the 1980s, many legal philosophers have argued that such statutes are unjust on the grounds that they punish character traits and feelings rather than actions and intentions. It is unjust to punish character traits and feelings, these authors have supposed, because character traits and feelings are not under agents' direct autonomous control. I argue that while it is unjust for governments to punish feelings and character traits, not all bias elements of crimes are feelings or character traits. Rather, some bias elements of crimes are intentions. I urge that in cases of biased crime in which the bias element in play is an intention, governments may punish the crime more severely than parallel non-biased crimes without violating the requirement not to punish what is not under agents' direct autonomous control.

We discuss in detail the dependence of second harmonic generation, third harmonic generation, and the Kerr effects on the doping level, the gap, and the electric field amplitude. The numerical results for weak electric fields agree with those calculated from available analytic perturbation formulas. For strong electric fields when saturation effects are important, all the effective third order nonlinear response coefficients show a strong field dependence.

description: We consider the phenomenon of natural optical activity, and related chiral magnetic effect in metals with low carrier concentration. To reveal the correspondence between the two phenomena, we compute the optical conductivity of a noncentrosymmetric metal to linear order in the wave vector of the light wave, specializing to the low-frequency regime. We show that it is the orbital magnetic moment of quasiparticles that is responsible for the natural optical activity, and thus the chiral magnetic effect. While for purely static magnetic fields the chiral magnetic effect is known to have a topological origin and to be related to the presence of Berry curvature monopoles (Weyl points) in the band structure, we show that the existence of Berry monopoles is not required for the dynamic chiral magnetic effect to appear; the latter is thus not unique to Weyl metals. The magnitude of the dynamic chiral magnetic effect in a material is related to the trace of its gyrotropic tensor. We discuss the conditions under which this trace is non-zero; in noncentrosymmetric Weyl metals it is found to be proportional to the energy-space dipole moment of Berry curvature monopoles. The calculations are done within both the semiclassical kinetic equation, and Kubo linear response formalisms, with coincident results.

description: This thesis analyzes three sequences from the Abbey of Saint-Denis for the feast of St. Denis, as preserved in the 13th-century notated missal F:Pn, lat. 1107. Each of these three sequences - Gaude turma triumphalis, Alludat vox ecclesiae, and Gaude prole, Graecia - either exists in a version unique to the abbey or survives in no other source, although two are contrafacts of earlier sequences. All are noteworthy for their political subtexts, alluding to the French monarchy and its place in society, or to the age and prestige of the Abbey of Saint-Denis. These political references are reinforced by musical devices, such as melismas, modal structure, and melodic repetition. Thus, these three sequences are relics of one medieval abbey's construction of its image and social role through the music of the liturgy.

description: Gapped quantum liquids (GQL) include both topologically ordered states (with long range entanglement) and symmetry protected topological (SPT) states (with short range entanglement). In this paper, we propose a classification of 2+1D GQL for both bosonic and fermionic systems: 2+1D bosonic/fermionic GQLs with finite on-site symmetry are classified by non-degenerate unitary braided fusion categories over a symmetric fusion category (SFC) $\cal E$, abbreviated as $\text{UMTC}_{/\cal E}$, together with their modular extensions and total chiral central charges. The SFC $\cal E$ is $\text{Rep}(G)$ for bosonic symmetry $G$, or $\text{sRep}(G^f)$ for fermionic symmetry $G^f$. As a special case of the above result, we find that the modular extensions of $\text{Rep}(G)$ classify the 2+1D bosonic SPT states of symmetry $G$, while the $c=0$ modular extensions of $\text{sRep}(G^f)$ classify the 2+1D fermionic SPT states of symmetry $G^f$. Many fermionic SPT states are studied based on the constructions from free-fermion models. But it is not clear if free-fermion constructions can produce all fermionic SPT states. Our classification does not have such a drawback. We show that, for interacting 2+1D fermionic systems, there are exactly 16 superconducting phases with no symmetry and no fractional excitations (up to $E_8$ bosonic quantum Hall states). Also, there are exactly 8 $Z_2\times Z_2^f$-SPT phases, 2 $Z_8^f$-SPT phases, and so on. Besides, we show that two topological orders with identical bulk excitations and central charge always differ by the stacking of the SPT states of the same symmetry.

General-relativistic force-free pulsar magnetospheres

description: Pulsar magnetospheres are shaped by ultra-relativistic electron/positron plasmas flowing in a strong magnetic field and subject to strong gravitational fields. The former induces magnetospheric currents and space charges responsible for the distortion of the electromagnetic field based on pure electrodynamics. The latter induces other perturbations in these fields based on space-time curvature. The force-free approximation describes the response of this magnetosphere to the presence of currents and charges and has been investigated by many authors. In this context, general relativity has been less discussed to quantify its influence on the neutron star electrodynamics. It is the purpose of this paper to compute general-relativistic force-free pulsar magnetospheres for realistic magnetic field configurations such as the inclined dipole. We performed time-dependent simulations of Maxwell equations in the 3+1 formalism of a stationary background metric in the slow-rotation approximation. We computed the resulting Poynting flux depending on the ratio~$R/\rlight$ and on frame-dragging through the spin parameter~$\as$, $R$ is the neutron star radius and $\rlight$ the light-cylinder radius. Both effects act together to increase the total Poynting flux seen by a distant observer by a factor up to~2 depending on the rotation rate. Moreover we retrieve the $\sin^2χ$ dependence of this luminosity, $χ$ being the obliquity of the pulsar, as well as a braking index close to $n=3$. We also show that the angular dependence of the Poynting flux scales like $\sin^2\vartheta$ for the aligned rotator but like $\sin^4\vartheta$ for the orthogonal rotator, $\vartheta$ being the colatitude.

description: The present paper deals with the classical question how a psychological experience, in this case apparent lightness, is linked by intervening neural processing to physical variables. We address two methodological issues: (a) how does one know the appropriate physical variable (what is the right x ?) to look at, and (b) how can behavioral measurements be used to probe the internal transformation that leads to psychological experience. We measured so-called lightness transfer functions (LTFs), that is the functions that describe the mapping between retinal luminance and perceived lightness for naturalistic checkerboard stimuli. The LTFs were measured for different illumination situations: plain view, a cast shadow, and an intervening transparent medium. Observers adjusted the luminance of a comparison patch such that it had the same lightness as each of the test patches. When the data were plotted in luminance–luminance space, we found qualitative differences between mapping functions in different contexts. These differences were greatly diminished when the data were plotted in terms of contrast. On contrast–contrast coordinates, the data were compatible with a single linear generative model. This result is an indication that, for the naturalistic scenes used here, lightness perception depends mostly on local contrast. We further discuss that, in addition to the mean adjustments, one may fi nd it useful to consider also the variability of an observer’s adjustments in order to infer the true luminance-to-lightness mapping function.
When allies act: the role of European public opinion in the 2011 military intervention in Libya

description: This thesis investigates the conditions under which decisions for military intervention are constrained by public opinion. Prior studies have identified electoral cycles and legislative checks as potential constraints on foreign policy making, but the interaction of these constraints and public opinion has gone largely unobserved. This thesis utilizes the 2011 NATO intervention in Libya as a case study to test whether the presence of upcoming elections or strong legislative checks on military deployment decisions are sufficient to motivate governments to make decisions about military intervention that are consistent with public opinion. My findings suggest that governments are chiefly constrained to public opinion through immediate electoral pressures. Strong legislative checks on foreign policy failed to prove sufficient to constrain foreign policy to opinion. These findings suggest that the inclusion of public opinion is critical for foreign policy analysis. Also, with NATO contributions held hostage by electoral time horizons and public sentiment, it may be difficult for NATO to move beyond shifting coalitions of those willing to contribute to missions.
School Consolidation in the Unequal City: How Race and Class Shape Efforts to Change Urban Education

description: School segregation is a fundamental feature of American education. Although efforts to integrate schools reached their peak in the 1960s and 1970s, in the 21st century there has been little political appetite to combat the issue. This dissertation examines an atypical example of contemporary school integration. I trace the complex story behind the consolidation of two adjacent neighborhood elementary schools in Chicago: one that is plurality white and has a small share of low income students and the other that is predominantly Black and low income. I use this case to explore questions of race, power, and justice. In doing so, I draw on 116 interviews with 96 respondents, 90 hours of participant observation, document analysis, and archival research. I demonstrate how the politics of race and class played into all aspects of the consolidation: the origins, resistance to, and then ultimate pursuit of the idea by a committed group of parents and community members. I follow this group’s efforts, highlighting the non-confrontational tactics they use to convince the school district to change the institutional status quo and consolidate the schools. I argue that once the consolidated school opens, familiar tensions arise around race, power, and building community. Finally, I step back to reconsider and reframe the consolidation story. I argue that the question of consolidation was the wrong one overall, and instead suggest a more radical approach centering racial justice for Black students and their families. I end by using my radical imaginary to put forth ways that this kind of justice could be achieved. My findings contribute to the broader understanding of the ways in which race and class shape American education and advance our conversation about the meaning of racial justice.
