description: We address the problem of constructing dynamically corrected gates for non-Markovian open quantum systems in settings where limitations on the available control inputs and/or the presence of control noise make existing analytical approaches unfeasible. By focusing on the important case of singlet-triplet electron spin qubits, we show how ideas from optimal control theory may be used to automate the synthesis of dynamically corrected gates that simultaneously minimize the system's sensitivity against both decoherence and control errors. Explicit sequences for effecting robust single-qubit rotations subject to realistic timing and pulse-shaping constraints are provided, which can deliver substantially improved gate fidelity for state-of-the-art experimental capabilities.

Effects of lessons in Schenkerian analysis upon students' performances of tonal works
Creators: name: Nakajima, Ayako Karen
Publisher: name: University of British Columbia
Year: 2013

description: This project focuses on performers’ first-hand experiences with Schenkerian analysis and its application to performance. Although some research in Schenkerian analysis and performance is in the current literature, the amount involving actual performers is miniscule. Therefore, I worked with music students from the University of British Columbia and, with each performer, went through a Schenkerian analysis of a tonal work that he or she had selected and performed. After a few weeks to practise and rehearse, all participants performed in a recital. Performances from before the lesson, the dress rehearsal, and the recital were recorded. Qualitative and quantitative data were collected through participant surveys given periodically throughout the experiment, and observations were made during the lesson and on the recordings of the pre- and post-lesson interpretations. The general consensus of the influence of Schenkerian analysis on the performer’s interpretation was positive. The most mentioned interpretation alterations were changes in the phrasing and pacing, followed by an easier ability to conceptualize the piece as a whole, rather than many small details attached together. Some elements improved participants’ understanding of the piece but did not generate any change in interpretation. Also, the relevance of the Urlinie is questionable. Audible differences in the pre- and post-lesson recordings include those of phrasing and shaping of phrases, breath marks to highlight the phrasing, and fluctuation in tempo. Yet, many elements also remained the same in both pre- and post-lesson performances. Schenkerian analysis was used as a supplement to the performer’s own background and influences in creating an interpretation and equipped the performers with another useful tool to aid in interpretation, but did not limit the use of other tools. Limited knowledge and time are two factors that worked against the performers' ability to incorporate Schenkerian analysis into their performance preparation.

description: We establish that for q>=1, the class of convex combinations of q translates of a smooth probability density has local doubling dimension proportional to q. The key difficulty in the proof is to control the local geometric structure of mixture classes. Our local geometry theorem yields a bound on the (bracketing) metric entropy of a class of normalized densities, from which a local entropy bound is deduced by a general slicing procedure.

Policing and public health : experiences of people who inject drugs in Bangkok, Thailand
Creators: name: Hayashi, Kanna
Publisher: name: University of British Columbia
Year: 2013

description: Background: In recent years, Thailand has intensified policing efforts as a strategy to address a continuing epidemic of illicit drug use. Thailand’s “war on drugs” campaign of 2003 received international criticism due to extensive human rights violations. However, few studies have since investigated the impacts of drug policing on people who inject drugs (IDU) in this setting. Drawing on the Risk Environment Framework, this dissertation sought to: explore IDUs’ lived experiences with police; identify the prevalence and correlates of experiencing beatings and drug testing by police; examine the relationship between exposures to policing and syringe sharing; and assess changes in the availability of illicit drugs among IDU in Bangkok, Thailand. Methods: Between June 2009 and June 2012, a community-recruited sample of IDU in Bangkok participated in a serial cross-­sectional mixed-­methods study and completed interviewer-­administered questionnaires and semi-structured in-­depth interviews. Audio-­recorded interviews were transcribed verbatim and a thematic analysis was conducted to document the character of IDUs’ encounters with police. A variety of multivariate regression techniques were used to estimate independent relationships between exposures to specific policing tactics and indicators of drug-­related harm, as well as to examine a temporal trend of street-­level availability of illicit drugs. Results: Respondents’ narratives indicated that drug policing involved numerous forms of human rights infringements and negatively influenced healthcare access among IDU in Bangkok. Reports of beatings and drug testing by police were common (38% and 67%, respectively) and were independently associated with various indicators of drug-­related harm, including syringe sharing and barriers to healthcare. Street-­level availability of illicit drugs increased significantly between 2009 and 2011. Conclusions: The findings indicate that the over-reliance on repressive drug policing is not suppressing the illegal drug market and is instead contributing to police-­perpetrated abuses, the perpetuation of risky injection behaviour, and an impediment to healthcare among IDU in Bangkok. These findings raise concern about the ongoing policing practices and point to the need for providing greater police oversight, as well as a shift toward more balanced approaches to drug control in this setting.

description: In order to study the behaviour of discrete dynamical systems under adiabatic cyclic variations of their parameters, we consider discrete versions of adiabatically-rotated rotators. Paralleling the studies in continuous systems, we generalize the concept of geometric phase to discrete dynamics and investigate its presence in these rotators. For the rotated sine circle map, we demonstrate an analytical relationship between the geometric phase and the rotation number of the system. For the discrete version of the rotated rotator considered by Berry, the rotated standard map, we further explore this connection as well as the role of the geometric phase at the onset of chaos. Further into the chaotic regime, we show that the geometric phase is also related to the diffusive behaviour of the dynamical variables and the Lyapunov exponent.

We also study the nonrelativistic bound states for a neutral particle interacting with a Coulomb-like potential based on the Lorentz symmetry violation background given by a fixed vector field parallel to the radial direction.

description: Despite the fact that the integral form of the equations of classical electrodynamics is well known, the same is not true for non-abelian gauge theories. The aim of the present paper is threefold. First, we present the integral form of the classical Yang-Mills equations in the presence of sources, and then use it to solve the long standing problem of constructing conserved charges, for any field configuration, which are invariant under general gauge transformations and not only under transformations that go to a constant at spatial infinity. The construction is based on concepts in loop spaces and on a generalization of the non-abelian Stokes theorem for two-form connections. The third goal of the paper is to present the integral form of the self dual Yangs-Mills equations, and calculate the conserved charges associated to them. The charges are explicitly evaluated for the cases of monopoles, dyons, instantons and merons, and we show that in many cases those charges must be quantized. Our results are important in the understanding of global properties of non-abelian gauge theories.

description: We derive an exact formula for the cusp anomalous dimension at small angles. This is done by relating the latter to the computation of certain 1/8 BPS Wilson loops which was performed by supersymmetric localization. This function of the coupling also determines the power emitted by a moving quark in N=4 super Yang Mills, as well as the coefficient of the two point function of the displacement operator on the Wilson loop. By a similar method we compute the near BPS expansion of the generalized cusp anomalous dimension.

description: Since the inception of the Individuals with Disabilities Education Act (IDEA), school districts throughout the United States have found themselves on the losing end in the battle to keep special education teachers (SETs) in the classroom. The SET shortage cripples schools’ ability to provide individuals with exceptionalities (IWEs) with a free and appropriate education as promised in IDEA. Despite the long-term devastation that the SET staffing crisis has inflicted upon historically marginalized students, policymakers at the federal, state, and local levels fail to capitalize on the experiences of the individuals who are closest to the problem: the special education teachers. This dissertation aimed to legitimize the lived experiences of 27 former and current K-12 special education inclusion teachers in urban, Mid-Atlantic school districts to understand the aspects of caseload management that have the greatest influence on SET burnout and attrition. Using a convergent parallel mixed-methods design, this study described participants’ prior experiences, as well as the process of co-constructing a caseload policy designed to decrease SET exhaustion and intent to leave. Overwhelming administrative duties, large caseloads, insufficient planning time, role conflict, and a lack of support from general educators and school administrators, contributed to SETs’ emotional and physical depletion, and their motivation to leave special education. The results also suggested that many schools did not have the proper infrastructure to provide SETs with the appropriate working conditions that are needed to optimally serve students who are the most removed from opportunity. Recommendations include the establishment of caseload policies that guarantee reasonable workloads for SETs, required special education coursework in administrator and general educator preparation programs, induction programs to support novice SETs, and full, equitable funding of IDEA.

description: We consider finite energy and $L^2$ differential forms associated with strongly local regular Dirichlet forms on compact connected topologically one-dimensional spaces. We introduce notions of local exactness and local harmonicity and prove the Hodge decomposition, which in our context says that the orthogonal complement to the space of all exact 1-forms coincides with the closed span of all locally harmonic 1-forms. Then we introduce a related Hodge Laplacian and define a notion harmonicity for finite energy 1-forms. As as corollary, under a certain capacity-separation assumption, we prove that the space of harmonic 1-forms is nontrivial if and only if the classical Čech cohomology is nontrivial. In the examples of classical self-similar fractals these spaces typically are either trivial or infinitely dimensional. Finally, we study Navier-Stokes type models and prove that under our assumptions they have only steady state divergence-free solutions. In particular, we solve the existence and uniqueness problem for the Navier-Stokes and Euler equations for a large class of fractals that are topologically one-dimensional but can have arbitrary Hausdorff and spectral dimensions.
Evidence for extra radiation? Profile likelihood versus Bayesian posterior

Publisher: name: arXiv
Year: 2011
Subjects: subject: Cosmology and Nongalactic Astrophysics (astro-ph.CO)
subject: FOS: Physical sciences

description: A number of recent analyses of cosmological data have reported hints for the presence of extra radiation beyond the standard model expectation. In order to test the robustness of these claims under different methods of constructing parameter constraints, we perform a Bayesian posterior-based and a likelihood profile-based analysis of current data. We confirm the presence of a slight discrepancy between posterior- and profile-based constraints, with the marginalised posterior preferring higher values of the effective number of neutrino species N_eff. This can be traced back to a volume effect occurring during the marginalisation process, and we demonstrate that the effect is related to the fact that cosmic microwave background (CMB) data constrain N_eff only indirectly via the redshift of matter-radiation equality. Once present CMB data are combined with external information about, e.g., the Hubble parameter, the difference between the methods becomes small compared to the uncertainty of N_eff. We conclude that the preference of precision cosmological data for excess radiation is "real" and not an artifact of a specific choice of credible/confidence interval construction.

This class represents a quantization of the PageRank protocol currently employed to list web pages according to their importance. We have found an instance of this class of quantum protocols that outperforms its classical counterpart and may break the classical hierarchy of web pages depending on the topology of the web.

description: Das Bundesministerium für Ernährung, Landwirtschaft und Verbraucherschutz (BMELV) wird die Düngeverordnung (DüV) novellieren. Vorschläge für Veränderungen wurden von einer Bund-Länder-Arbeitsgruppe (BLAG) im Auftrag des BMELV erarbeitet. Diese Vorschläge sehen unter anderem vor, die Kategorie der anzurechnenden organischen Dünger um den Bereich der Gärreste aus Biogasanlagen und Klärschlämme zu erweitern.Da insbesondere in den norddeutschen Veredlungs- und Milcherzeugungsregionen eine enge räumliche Verknüpfung zwischen der Tierhaltung und der Biogaserzeugung gegeben ist, wurden auf der Datenbasis des Bundeslandes Schleswig-Holstein die zu erwartenden Effekte entsprechend der Vorschläge der BLAG auf den Anfall organischer N-Dünger auf Landes- und Kreisebene kalkuliert.Die zusätzliche Anrechnung der oben aufgeführten organischen N-Dünger erhöht den landesweiten N-Anfall aus organischen Düngern (N-Ausscheidungen abzüglich Stall- und Lagerverluste) um 25 kg N/ha auf 110 kg N/ha effektiv verfügbarer landwirtschaftlicher Nutzfläche (LN). Die effektiv verfügbare LN ergibt sich aus der LN abzüglich der Flächen, die z.B. aufgrund von Agrarumweltmaßnahmen nicht für die Applikation organischer Dünger genutzt werden können. Unter Berücksichtigung der maximal zu applizierenden organischen Düngung in Höhe von 170 kg N/ha zeigen die Ergebnisse, dass in einigen Landkreisen mit gleichzeitig intensiver Tierhaltung und Biogaserzeugung die Flächenverfügbarkeit zur Ausbringung organischer N-Dünger limitiert ist.Vorausgesetzt, die gesamte effektiv verfügbare LN eines jeden Landkreises stünde für die Applikation von 170 kg N/ha aus organischen Düngern zur Verfügung, würden die Flächen in allen Landkreisen ausreichen, um die Vorgaben einer novellierten DüV zu erfüllen.Bereits bei einer Einschränkung der effektiven Flächenverfügbarkeit um 10 % sind jedoch Exporte aus einzelnen Landkreisen erforderlich.Bei einer derzeit angenommenen realistischen Flächenverfügbarkeit von 80% der effektiven LN für die Applikation organischer Dünger müssen bereits Gülle und Gärreste in einem Umfang von ca. 1.000.000 Tonnen Frischmasse über Kreisgrenzen hinweg exportiert werden, was zu LKW-Transportkosten von mehr als 5 Millionen Euro und transportbedingten zusätzlichen CO2-Emissionen von über 2.600 Tonnen CO2 führen würde. Die daraus resultierenden Anpassungsstrategien werden diskutiert.

description: We investigate the no-boundary measure in the context of moduli stabilization. To this end, we first show that for exponential potentials, there are no classical histories once the slope exceeds a critical value. We also investigate the probability distributions given by the no-boundary wave function near maxima of the potential. These results are then applied to a simple model that compactifies 6D to 4D (HBSV model) with fluxes. We find that the no-boundary wave function effectively stabilizes the moduli of the model. Moreover, we find the a priori probability for the cosmological constant in this model. We find that a negative value is preferred, and a vanishing cosmological constant is not distinguished by the probability measure. We also discuss the application to the cosmic landscape. Our preliminary arguments indicate that the probability of obtaining anti de Sitter space is vastly greater than for de Sitter.

description: Die Gewährleistung einer sicheren und zukunftsfähigen Energieversorgung in Deutschland ist ein zentrales Ziel der Bundesregierung. In Folge dessen wird in vielen Kommunen die Produktion erneuerbarer Energien verstärkt ausgebaut. In einem Forschungsvorhaben wurde vor diesem Hintergrund untersucht, inwiefern Flurbereinigungsverfahren einen Beitrag zur gesellschaftlich akzeptierten Energiebereitstellung leisten können. Im Rahmen einer energetischen Flurbereinigung gilt es zunächst vorab zu klären, ob und inwieweit regionale Energieautarkie für die Strom- und/oder Wärmeversorgung angestrebt wird. Hierfür ist die gegenwärtige und zukünftige regionale Energienachfrage zu ermitteln und mit den technischen (wirtschaftlichen) Potenzialen der Produktion regenerativer Energien (das heißt, nicht allein der Bioenergie) abzustimmen. Dabei ist die weitere Abstimmung mit anderen regionalen Zielsetzungen, zum Beispiel von Naturschutzzielen, als auch mit verschiedenen Interessengruppen bezüglich Akzeptanz sowie deren Abnahme- und Produktionsbereitschaft von erneuerbaren Energien unentbehrlich. Der energetische Gedanke muss möglichst früh in der Vorbereitungsphase der Flurberei­nigung implementiert werden. Gründe hierfür sind neben der Erörterung günstiger Energiegestehungskosten sowie potenzieller Standorte der Energieproduktion und ein darauf abgestimmtes Flächen-, Wege- als auch (Energie-)Einspeisungsnetz auch die Klärung von Eigentumsverhältnissen, insbesondere bei gemeinschaftlichem Anlagenbau. Die Erweiterung einer Flurbereinigung um die Betrachtung der energetischen Nutzung orientiert sich somit sowohl an privaten als auch an staatlichen Interessen. Hierbei ist das eigentliche Flurbereinigungsverfahren nicht nur mit den Aspekten energetischer Landnutzung zu erweitern, sondern auch an die Orts- und Regionalplanung zu koppeln. Diese entscheidet über den zukünftigen Energiebedarf vor Ort und stellt weitere Energiegewinnungsmöglichkeiten zur Verfügung. In der Summe kann der volkswirtschaftliche Nutzen einer auch energetisch motivierten Flurbereinigung die höheren Kosten im Vergleich zu einer Flurbereinigung ohne Berücksichtigung energetischer Kalküle überkompensieren.

description: Se a partire dagli anni Novanta l’allattamento e la percezione del neonato attraverso la pelle, l’osservazione della placenta e il taglio del cordone ombelicale, sono stati incoraggiati come forme di valorizzazione del corpo del neonato, anche il confronto con il corpo del bambino morto è individuato come momento essenziale della dolorosa elaborazione del lutto. Allo stesso modo la conoscenza dei genitori biologici è vista come fondamentale esperienza identitaria dei figli adottati o concepiti tramite donazione di sperma, e nel trapianto degli organi il corpo del donatore condiziona nel trapiantato l’eventuale rischio di rigetto. Intorno alla nascita e alla morte si sviluppa così una focalizzazione sulla ‘carne’ e sul corpo come fondamentale supporto della costruzione identitaria. Il volume qui tradotto si interroga sui meccanismi dei profondi cambiamenti culturali e ideologici intervenuti nei processi di inizio e fine vita e nella conseguente gestione del corpo.

description: Pferdesport und -zucht haben sich in den vergangenen drei bis vier Jahrzehnten zu einem bedeutenden Wirtschaftsfaktor entwickelt. Eine Marktanalyse der Deutschen Reiterlichen Vereinigung (FN) ergab, dass der Beitrag des Pferdes zum Bruttosozialprodukt der Bundesrepublik Deutschland rund fünf Milliarden Euro beträgt. Etwa eine Million Pferde leben heute wieder auf dem Gebiet der Bundesrepublik. Da für drei bis vier Pferde ein Arbeitsplatz geschaffen wird, beschäftigen aktuell Pferdezucht und -sport permanent etwa 300.000 Menschen.Statistische Auswertungen belegen zusätzlich, dass Deutschland – sowohl bei der Zahl der Reiter als auch bei der Anzahl an Pferden – eine Spitzenposition in Europa einnimmt. Die Erfolge von Pferden aus deutscher Zucht genießen weltweit hohe Anerkennung.Die Pensionspferdehaltung hat sich zu einer speziellen Einkommensalternative für zahlreiche landwirtschaftliche Betriebe – vor allem in Großstadtnähe – entwickelt. Der wesentliche Unterschied zur herkömmlichen landwirtschaftlichen Produktion ist der Dienstleistungscharakter dieser Arbeit.Die Entwicklung der Pferdehaltung, weg vom Nutztier hin zum Freizeitgefährten, brachte auch eine Veränderung in den Haltungsbedingungen für Pferde mit sich.Moderne, helle und gut klimatisierte Stallungen sind heute wesentlich tiergerechter als frühere (= vorzugsweise ältere Anbindehaltungen). Darüber hinaus bieten sie den darin tätigen Menschen auch komfortablere Arbeitsbedingungen als früher.Die Pferdezucht und -haltung gehört – trotz ihrer spezifischen Probleme, die jeder Betriebszweig mit sich bringt – nicht zu den großen ‚Sorgenkindern’ in der aktuellen agrarpolitischen Diskussion bzw. in zugehörigen Tierschutzdebatten. Es ist offensichtlich gut gelungen, die Pferdehaltung auf den noch einzigen wichtigen Verwendungszweck, den Einsatz in der Freizeitgestaltung, abzustimmen und einzustellen.

The Néel-VBS transition in three-dimensional SU($N$) antiferromagnets

description: We present results for the phase diagram of an SU($N$) generalization of the Heisenberg antiferromagnet on a bipartite three-dimensional anisotropic cubic (tetragonal) lattice as a function of $N$ and the lattice anisotropy $γ$. In the "isotropic" $γ=1$ cubic limit, we find a transition from Néel to valence bond solid (VBS) between N=9 and N=10. We follow the Néel-VBS transition to the limiting cases of $γ\ll 1 $ (weakly coupled layers) and $γ\gg 1$ (weakly coupled chains). Throughout the phase diagram we find a direct first-order transition from Néel at small-$N$ to VBS at large-$N$. In the three-dimensional models studied here, we find no evidence for either an intervening spin-liquid "photon" phase or a continuous transition, even close to the limit $γ\ll 1$ where the isolated layers undergo continuous Néel-VBS transitions.

A homological study of Green polynomials

Publisher: name: arXiv
Year: 2011
Subjects: subject: Representation Theory (math.RT)

description: We interpret the orthogonality relation of Kostka polynomials arising from complex reflection groups (c.f. [Shoji, Invent. Math. 74 (1983), J. Algebra 245 (2001)] and [Lusztig, Adv. Math. 61 (1986)]) in terms of homological algebra. This leads us to the notion of Kostka system, which can be seen as a categorical counter-part of Kostka polynomials. Then, we show that every generalized Springer correspondence [Lusztig, Invent. Math. 75 (1984)] (in good characteristic) gives rise to a Kostka system. This enables us to see the top-term generation property of the (twisted) homology of generalized Springer fibers, and the transition formula of Kostka polynomials between two generalized Springer correspondences of type $\mathsf{BC}$. The latter provides an inductive algorithm to compute Kostka polynomials by upgrading [Ciubotaru-Kato-K, Invent. Math. 178 (2012)] §3 to its graded version. In the appendices, we present purely algebraic proofs that Kostka systems exist for type $\mathsf{A}$ and asymptotic type $\mathsf{BC}$ cases, and therefore one can skip geometric sections §3--5 to see the key ideas and basic examples/techniques.

Is there any coherent measure for eternal inflation?

description: An eternally inflating universe produces an infinite amount of spatial volume, so every possible event happens an infinite number of times, and it is impossible to define probabilities in terms of frequencies. This problem is usually addressed by means of a measure, which regulates the infinities and produces meaningful predictions. I argue that any measure should obey certain general axioms, but then give a simple toy model in which one can prove that no measure obeying the axioms exists. In certain cases of eternal inflation there are measures that obey the axioms, but all such measures appear to be unacceptable for other reasons. Thus the problem of defining sensible probabilities in eternal inflation seems not be solved.

description: We study some properties of the $SU(1,1)$ Perelomov number coherent states. The Schrödinger's uncertainty relationship is evaluated for a position and momentum-like operators (constructed from the Lie algebra generators) in these number coherent states. It is shown that this relationship is minimized for the standard coherent states. We obtain the time evolution of the number coherent states by supposing that the Hamiltonian is proportional to the third generator $K_0$ of the $su(1,1)$ Lie algebra. Analogous results for the $SU(2)$ Perelomov number coherent states are found. As examples, we compute the Perelomov coherent states for the pseudoharmonic oscillator and the two-dimensional isotropic harmonic oscillator.

description: We present a method of implementing ultrafast two-qubit gates valid for the ultrastrong coupling (USC) and deep strong coupling (DSC) regimes of light-matter interaction, considering state-of-the-art circuit quantum electrodynamics (QED) technology. Our proposal includes a suitable qubit architecture and is based on a four-step sequential displacement of an intracavity mode, operating at a time proportional to the inverse of the resonator frequency. Through ab initio calculations, we show that these quantum gates can be performed at subnanosecond time scales, while keeping the fidelity above 99%.
