description: Spins based in silicon provide one of the most promising architectures for quantum computing. A scalable design for silicon-germanium quantum dot qubits is presented. The design incorporates vertical and lateral tunneling. Simulations of a four-qubit array suggest that the design will enable single electron occupation of each dot of a many-dot array. Performing two-qubit operations has negligible effect on other qubits in the array. Simulation results are used to translate error correction requirements into specifications for gate-voltage control electronics. This translation is a necessary link between error correction theory and device physics.

description: Density-reconstruction sharpens the baryon acoustic oscillations signal by undoing some of the smoothing incurred by nonlinear structure formation. In this paper we present an analytical model for reconstruction based on the Zeldovich approximation, which for the first time includes a complete set of counterterms and bias terms up to quadratic order and can fit real and redshift-space data pre- and post-reconstruction data in both Fourier and configuration space over a wide range of scales. We compare our model to n-body data at $z = 0$ from the {\tt DarkSky} simulation \cite{skillman14}, finding sub-percent agreement in both real space and in the redshift-space power spectrum monopole out to $k = 0.4\ h$ Mpc$^{-1}$, and out to $k = 0.2\ h$ Mpc$^{-1}$ in the quadrupole, with comparable agreement in configuration space. We compare our model with several popular existing alternatives, updating existing theoretical results for exponential damping in wiggle/no-wiggle splits of the BAO signal and discuss the usually-ignored effect of higher bias contributions on the reconstructed signal. In the appendices, we re-derive the former within our formalism, present exploratory results on higher-order corrections due to nonlinearities inherent to reconstruction, and present numerical techniques with which to calculate the redshift-space power spectrum of biased tracers within the Zeldovich approximation.

description: Explicit formulae are given for the saddle connection for an integrable family of standard maps studied by Suris. A generalization of Melnikov's method shows that, upon perturbation, this connection is destroyed. We give explicit formula for the first order approximation of the area of the lobes of the resultant turnstile. It is shown that the lobe area is exponentially small in the limit when the Suris map approaches the trivial twist map.

description: We consider a system where a spherical particle is suspended in a nematic liquid crystal confined between two walls. We calculate the liquid-crystal mediated potential of mean force between the sphere and a substrate by means of Monte Carlo simulations. Three methods are used: a traditional Monte Carlo approach, umbrella sampling, and a novel technique that combines canonical expanded ensemble simulations with a recently proposed density of states formalism. The latter method offers clear advantages in that it ensures good sampling of phase space without prior knowledge of the energy landscape of the system. The resulting potential of mean force, computed as a function of the normal distance between the sphere and a surface, suggests that the sphere is attracted to the surface, even in the absence of attractive molecular interactions.

description: We present molecular dynamics computer simulations of filaments of model non-Newtonian liquid stretched in a uniaxial deformation to the point of breaking. The liquid consists of Lennard-Jones monomers bound into chains of 100 monomers by nonlinear springs, and several different constant velocity and constant strain rate deformations are considered. Generally we observe nonuniform extensions originating in an interplay between the stretching forces and elastic and capillary restoring mechanisms, leading to highly uneven shapes and alternating stretched and unstretched regions of liquid. Except at the fastest pulling speeds, the filaments continue to thin indefinitely and break only when depleted of molecules, rather than common viscoelastic rupture mechanisms.

description: This dissertation investigates the evolving notions of verisimilitude and pictorial objectivity in eighteenth-century France through wax-based objects. I identify three case studies and examine the truth claims that were made about them: polychrome wax sculpture by Antoine Benoist (1632-1717) and Gaetano Giulio Zumbo (c.1656-1701) at the turn of the century; an attempt by the Comte de Caylus (1692-1765) to resurrect ancient encaustic painting in the early 1750s; anatomical models by Honoré Fragonard (1732-1799) and André Pierre Pinson (1746- 1828) during the latter decades of the century. In all cases, wax objects and associated truth claims addressed specific domains of specialized knowledge and practice. Benoist and Zumbo’s sculpture took part of period debates about pictorial verisimilitude, while Caylus proposed encaustic painting as an alternative method of accessing historical past. By contrast, Fragonard and Pinson’s work challenged the evidentiary and pedagogical value of anatomical models. My dissertation identifies potential origins of modern dependency on, as well as skepticism towards, what counts as reliable or legitimate visual information. By addressing objects and their makers that have not received substantial scholarly attention, I demonstrate how they resisted increasingly rigid Enlightenment categories, even when their ostensible purposes were in line with the broader Enlightenment project. By extension, my project offers an opportunity to think more broadly about the viability of a medium as a conduit of information, whether in the rise of photography in the nineteenth century or in today’s debates about post-truth politics.

description: We discuss the behaviour of a quantum Hall system when two Landau levels with opposite spin and combined filling factor near unity are brought into energetic coincidence using an in-plane component of magnetic field. We focus on the interpretation of recent experiments under these conditions [Zeitler et al, Phys. Rev. Lett. 86, 866 (2001); Pan et al, Phys. Rev. B 64, 121305 (2001)], in which a large resistance anisotropy develops at low temperatures. Modelling the systems involved as Ising quantum Hall ferromagnets, we suggest that this transport anisotropy reflects domain formation induced by a random field arising from isotropic sample surface roughness.

Becoming and Being Aware and Engaged: An Exploration of the Development of Political Awareness and Participation Among Māori and Pākehā Secondary School Students in Aotearoa/New Zealand

Year: 2014
Subjects: Ethnology

description: This dissertation explores how political ideals, knowledge and participation are shaped, articulated and contested in and out of school for and by Maaori and Paakehaa secondary school students, school staff, families and communities with data generated through ethnographic research in Aotearoa/New Zealand (ANZ).  The state of education in ANZ is both stable and precarious; stable because it is a national school system with a standardized curriculum and hiring standards regardless of whether a school is public or private with a central unit (Ministry of Education) responsible for overseeing these elements and education policy; and precarious in the sense that the school-age population is becoming increasingly diverse and must meet the needs of Maaori and Paakehaa, as well as Pacific Islander and Asian students.  This is particularly imperative for Maaori and Pacific Islander children as they are less likely to have attended preschool when compared to their Paakehaa and Asian counterparts, and have higher dropout and unemployment rates.
      Schools are important sites of cultural production representing the nexus of unceasing, multidirectional exchanges of ideas, knowledge and practices contributing to students' development of political awareness and participation through school organization, pedagogy, and social relations.  Viewed through the lenses of the anthropology of education, learning and identity development, social and cultural capital, critical pedagogy and political literacy, I demonstrate the relationship between schooling, citizenship, society and identity using data I generated while conducting 15 months of ethnographic research in two secondary school settings: a state-integrated, coed Maaori boarding school, and a public, coed secondary school.  I underscore students' experiences in social interactions, and formal and informal education practices imbedded in particular historical, political, sociocultural and economic contexts.  I generated data utilizing research methods consisting of participant observation, interviews and surveys to document school and non-school events and experiences including cultural performances, assemblies, classroom sessions, field trips, staff and faculty meetings, in addition to protests, media coverage and court proceedings for Maaori activists and other political activists accused of domestic terrorism in October 2007.  Finally, I use the terrorism raids as a vehicle to discuss the role public pedagogy plays in educating the public, and relate my findings to the anthropological literature on indigenous movements and cultural homogenization to address the bidirectional interplay between globalizing forces and local effects on identity formation and cultural processes.
Renormalisation of pair correlations and their Fourier transforms for primitive block substitutions

description: For point sets and tilings that can be constructed with the projection method, one has a good understanding of the correlation structure, and also of the corresponding spectra, both in the dynamical and in the diffraction sense. For systems defined by substitution or inflation rules, the situation is less favourable, in particular beyond the much-studied class of Pisot substitutions. In this contribution, the geometric inflation rule is employed to access the pair correlation measures of self-similar and self-affine inflation tilings and their Fourier transforms by means of exact renormalisation relations. In particular, we look into sufficient criteria for the absence of absolutely continuous spectral contributions, and illustrate this with examples from the class of block substitutions. We also discuss the Frank-Robinson tiling, as a planar example with infinite local complexity and singular continuous spectrum.

description: We propose a high precision satellite experiment to further test Einstein's General Relativity and constrain extended theories of gravity. We consider the frequency shift of a photon radially exchanged between two observers located on Earth and on a satellite in circular orbit in the equatorial plane. In General Relativity there exists a peculiar satellite-distance at which the static contribution to the frequency shift vanishes since the effects induced by pure gravity and special relativity compensate, while it can be non-zero in modified gravities, like in models with screening mechanisms. As an experimental device placed on the satellite we choose a system of hydrogen atoms which can exhibit the $1$s spin-flip transition from the singlet (unaligned proton-electron spins) to the triplet (aligned proton-electron spins) state induced by the absorption of photons at $21.1$cm. The observation of an excited state would indicate that the frequency of the emitted and absorbed photon remains unchanged according to General Relativity. On the contrary, a non-zero frequency shift, as predicted in extended theories of gravity, would prevent the spin-flip transition and the hydrogen atoms from jumping into the excited state. Such a detection would signify a smoking-gun signature of new physics beyond special and general relativity.

description: Epigallocatechin gallate (EGCG) is a major polyphenols of green tea may have the possibility to inhibit epidermal growth factor receptor (EGFR) activity and lead to reduce non-small cell lung cancer (NSCLC) progression. However, EGCG has some toxic features; moreover, there is a lack of explorations into the molecular interaction mechanisms of EGCG and the EGFR. In this examination, integration of quantitative structure–activity relationship (QSAR) modeling, pharmacophore-based virtual screening, and ensemble docking approaches were used to predict potential novel EGCG analogs as effective EGFR inhibitors. QSAR modeling of logP and logS predictions and toxicity endpoint investigation for a set of 82 compounds were shown good predictive ability and robustness from the applicability domain and confusion matrix elucidations. Virtual screening and docking studies revealed that seven high potential EGCG analogs as strong EGFR binders. Molecular interactions interpretations indicated some insights into the structural features of ligands that efficiently interfere with mutation possible residues (Gly719 and Thr790) of the EGFR. The hydrogen bonds, hydrophobic interactions, atomic π-cation interactions and salt bridges of ligands are contributing additional stability to receptor structure, which can lead to blocking the intracellular protein-tyrosine kinase activity, including EGFR associated pathways activation in NSCLC. Therefore, this can characterize as a block-cluster mechanism between EGCG analogs and EGFR complexes. In silico anti-EGFR and anticancer activity predictions suggested that, ligands could act as promising pharmacological, anticancer, and drug-like templates of EGFR towards moderating the NSCLC progressions. These results and provided pinpoints could be beneficial to recognize probable therapeutic targets for NSCLC therapy.

description: The high prevalence and severe long term effects of Post Traumatic Stress Disorder (PTSD) in war veterans is well established. Living with a parent with depression or alcohol problems is known to be associated with increased risk of psychological disorder in offspring, but there has been little research on the possible effects on children of living with a father with chronic PTSD. The current thesis tested whether the offspring of Vietnam veterans with PTSD had high rates of psychological problems, and whether the risk of such problems was mediated by insecure parental attachment or negative family environment. Participants were 69 male Vietnam veterans with chronic PTSD and their families (spouses and 115 children) and 32 comparison males, who were similar in age and education to the veterans, but who had no history of psychiatric disorder, and their families (spouses and 55 children). Clinical interviews with the men were used to confirm psychiatric diagnosis, spouses completed self-reports of their psychological adjustment, and the family environment. Children completed self-report measures of parental attachment, and their own psychological adjustment. The offspring of fathers with PTSD had much higher depression, anxiety and anger, and lower self-esteem than comparison offspring, and these problems were more severe in sons than daughters of fathers with PTSD. The level of depression, anxiety and anger in the children of fathers with PTSD was mediated by insecure attachment and high family conflict. The offspring of fathers with chronic PTSD are at high risk for psychological problems, and family assistance promoting better father-child attachment and reducing family conflict might help prevent at least some of these problems.

description: Dieser Essay zielt - in klarer Unterscheidung gegenüber der kurz anzusprechenden soziologischen Untersuchung von Nachhaltigkeitskonzepten und -diskursen sozialer Akteure - darauf ab, die analytische Struktur und den begrifflich noch eindeutig bestimmbaren Gehalt des Konzepts einer nachhaltigen Entwicklung auf allgemeiner Ebene möglichst präzise herauszuarbeiten, ohne auf spezifische typische Problemstellungen (z.B. die Vereinbarkeit von Wirtschaftswachstum und nachhaltiger Entwicklung) einzugehen. Das Konzept sustainable development wird daher im Hinblick auf folgende Gesichtspunkte erörtert: seine formale Begrifflichkeit (Begriffs- und Konzeptanalyse), Herausarbeitung seiner zentralen Bezugsdimensionen (Belastungsgrenzen, Verteilungsgerechtigkeit, Umsetzungsstrategien), Darstellung der Struktur möglicher substantieller Aussagen (Negativbestimmung, formale Orientierung, situative Ausfüllung, trade-offs), Beschreibung seiner substantiellen Dimensionen (ökologische, soziale, wirtschaftliche Nachhaltigkeit) und die Struktur möglicher Strategien nachhaltiger Entwicklung (Anschlussfähigkeit, Übergangsprobleme, Pfadabhängigkeit). Dieses Vorgehen wird am Beispiel nachhaltiger Energieversorgung plausibilisiert. Abschließend wird nach dem Wert dieser analytischen Vorgehensweise für eine rationale Gestaltung sozialer Nachhaltigkeitsdiskurse gefragt.
description: Unlike the sociological study of sustainability concepts and discourses pursued by social actors, this essay aims at elaborating as clearly as possible the analytical structure and the conceptually still unequivocal substance of the concept sustainable development at a general level, without addressing specific typical problems (e.g. the compatibility of economic growth and sustainable development). Hence the following aspects of the concept sustainable development are discussed: its formal notions (analysis of terms and concept), its central reference points (limits to carrying capacity, distributional justice, strategies for realisation), the structure of feasible substantive statements (negative definition, formal orientation, contextual specification, tradeoffs), its substantive dimensions (ecological, social, economic sustainability), and the structure of possible sustainability strategies (linkability, problems of transition, path dependency). The plausibility of this procedure is demonstrated by the example of sustainable energy supply. Lastly, the benefit of this analytical perspective for a rational arrangement of sustainability discourses is addressed.

Automorphisms of one-relator groups

description: It is a well-known fact that every group $G$ has a presentation of the form $G = F/R$, where $F$ is a free group and $R$ the kernel of the natural epimorphism from $F$ onto $G$. Driven by the desire to obtain a similar presentation of the group of automorphisms $Aut(G)$, we can consider the subgroup $Stab(R) \subseteq Aut(F)$ of those automorphisms of $F$ that stabilize $R$, and try to figure out if the natural homomorphism $Stab(R) \to Aut(G)$ is onto, and if it is, to determine its kernel. Both parts of this task are usually quite hard. The former part received considerable attention in the past, whereas the latter, more difficult, part (determining the kernel) seemed unapproachable. Here we approach this problem for a class of one-relator groups with a special kind of small cancellation condition. Then, we address a somewhat easier case of 2-generator (not necessarily one-relator) groups, and determine the kernel of the above mentioned homomorphism for a rather general class of those groups.

description: Despite a steady stream of new science teachers joining the K-12 education workforce, the rate at which beginning science teachers (BSTs) stay in the classroom long-term is shockingly low. With such a low rate of retention, it is important to examine these teachers’ experiences in the formative first years of teaching after completing a formal pre-service program in order to observe their continual learning in-service. Though much attention has been given to formal mentoring and induction programs for BSTs, little is known about the ways these teachers choose to continue learning to teach science. Especially little is known about how technology can facilitate their continued learning. In this phenomenographic study, I followed a group of BSTs to describe their experiences and conceptions of their learning choices and agency during the induction period, which I define as the first through third year of teaching. By investigating induction, the period of rapid learning that occurs during the first years of teaching science full-time, I captured the experiences BSTs have that are unique to this time. Both qualitative and quantitative data were collected from surveys, observations, journal reflections, and interviews. The data indicate that BSTs’ learning needs are tied to a desire for professional connection to other educators, juxtaposed with a perception that they must be self-reliant in their work. BSTs learn primarily from their specific student population, through trial and error, and the extent and manner of these learnings depend on time, logistics, and the school context in which they work. Finally, BSTs demonstrate that technology plays a primarily pedagogical role in their classrooms, but promising themes emerged about ways in which they learn from and use technology to deprivatize teaching in order to meet their desire for professional connection.

description: In der vorliegenden Studie werden industriepolitische Handlungsfelder und Instrumente identifiziert und auf ihre Eignung für eine ökologische Industriepolitik in Deutschland analysiert. Die Ergebnisse leiten sich aus Fallstudien zu industriepolitischen Maßnahmen in Irland (IKT), Japan (Hochgeschwindigkeitszüge), Finnland (Telekommunikation) und den USA (Biotechnologie) ab. Für die Fälle werden die Entstehungsbedingungen und Handlungsnotwendigkeiten unterstützender Politik rekonstruiert. Dabei zeigt sich die Bedeutung der Förderung von Infrastrukturen, F&E; und der Qualifizierung von Arbeitskräften, die Notwendigkeit der Leistungsfähigkeit von Innovationssystemen sowie die Vorteilhaftigkeit von Innovationsclustern. Industriepolitische Maßnahmen adressieren typischer Weise eine Vielzahl von Akteuren mit einem umfassenden Instrumentenmix, sind langfristig ausgelegt und werden von verschiedenen Ressorts und auf unterschiedlichen Ebenen des politischen Systems entwickelt und umgesetzt. Um erfolgreich zu sein, müssen alle Phasen des Innovationsprozess berücksichtigt werden. Insbesondere für eine nachfrageorientierte Innovationspolitik können Beispiele aus den Fallstudien abgeleitet werden, die die Markteinführung und Diffusion von neuen Technologien und insbesondere umweltfreundlichen Technologien unterstützen können.

description: Selective laser melting (SLM) was successfully applied to fabricate strong and ductile reduced activation ferritic/martensitic (RAFM) steel by introducing heterogeneous multi-/bimodal microstructure. The SLM-built RAFM steel exhibited an excellent combination of strength and ductility (i.e. yield strength of 1053 ± 4.7 MPa and elongation of 16.9 ± 0.4%), well surpassing the previously reported counterparts. The superior strength was expected from the refined grains and lath martensites, and the high ductility was associated with the improved dislocation-controlled strain hardening capability. This work provides a basis for developing high-performance RAFM steel by microstructural design via SLM. A new strategy, refers to heterogeneous multi-/bimodal microstructure, is proposed to develop strong and ductile RAFM steel via SLM and the achieved superior mechanical properties overcome the classic strength-ductility trade-off.

description: Supply capability and strategic customer behavior jointly influence the operations management in a supply chain (SC). Few studies have been conducted to reflect such a composite impact from the supply side and the demand side. The aim of our article is to fill this gap by focusing on the SC facing strategic customers under demand and yield uncertainty. Specially, we emphasize the importance of replenishment tactic in keeping a stable supply level, and discuss the corresponding impact on the input quantity decision of the SC under yield uncertainty. Two scenarios are investigated: (i) without the market service-level (MSL) constraint and (ii) with the MSL constraint. The SCs under different scenarios are coordinated by various contracts. Meanwhile, by adjusting corresponding contract parameters, the SC members can achieve Pareto improvement. The numerical analyses are used to examine the validity of the conclusions derived.

description: Immunity, behavior, and circadian regulation are important ways that animals maintain homeostasis. Defects in these physiologies often lead to disease or even death, yet many questions remain about how these physiologies are related. I explored the interactions between innate immunity, behavior, and circadian regulation by using Drosophila melanogaster, a convenient, genetically tractable model organism with both functionally and molecularly conserved innate immune and circadian clock systems. In the first chapter, I show that feeding, a circadian-regulated behavior, increases immunity to a sepsis-like infection. In the second, I present evidence suggesting that aging-related changes in immunity may be linked to circadian defects. Finally, I use a novel automated method to demonstrate that reduced grooming is a conserved sickness behavior in Drosophila.
           The feeding project ultimately showed that mutating TORC2 components could increase the host’s ability to kill and clear a bacterial infection, as well as survive the pathogenic effects of infection. Therefore we have identified a possible drug target to create host-based therapies for sepsis patients. We also have established Drosophila as a model system for studying a conserved sickness behavior: reduced grooming. This experimental paradigm will allow researchers to isolate mutants that do not show reduced grooming, and investigate whether this sickness behavior is adaptive or not.
State-Society cycles and political pacts in a national-dependent society: Brazil

description: The history of independent Brazil may be divided into three major state- society cycles, and, after 1930, five political pacts or class coalitions can be identified. These pacts were nationalist; only in the 1990s the Brazilian elites surrender to the neoliberal hegemony. Yet, since the mid-2000s they have been rediscovering the idea of the nation. The main claim of this essay is that Brazilian elites and Brazilian society are “national-dependent”, that is, they are ambivalent and contradictory, requiring an oxymoron to define them. They are dependent because they often see themselves as “European” and the mass of the people as inferior. But Brazil is big enough, and there are enough common interests around its domestic market, to make the Brazilian nation less ambivalent. Today Brazil is seeking a synthesis between the last two political cycles – between social justice and economic development in the framework of democracy.
The characteristic exponents of the falling ball model

description: We study the characteristic exponents of the Hamiltonian system of $n$ ($\ge 2$) point masses $m_1,\dots,m_n$ freely falling in the vertical half line $\{q|\, q\ge 0\}$ under constant gravitation and colliding with each other and the solid floor $q=0$ elastically. This model was introduced and first studied by M. Wojtkowski. Hereby we prove his conjecture: All relevant characteristic (Lyapunov) exponents of the above dynamical system are nonzero, provided that $m_1\ge\dots\ge m_n$ (i. e. the masses do not increase as we go up) and $m_1\ne m_2$.
