description: This paper proposes an equivalent transmission-line circuit for on-chip inductors and derives the quality (Q) factor response in terms of the transmission-line circuit parameters in closed form. The derived formulas are general and suitable for all kinds of on-chip inductors to account for their frequency dependences of Q factors. For demonstration, a series of asymmetric inductors and another series of same valued symmetric inductors have been fabricated on the same silicon substrate. The measured Q-factor responses for both kinds of inductors agree quite well with the formula predictions. The symmetric inductors have a higher equivalent characteristic impedance so as to correspond to a higher peak Q-factor frequency than the asymmetric inductors. The presented formulas can also uniquely distinguish the improvement in Q-factor responses due to the reduction of conductor loss or dielectric loss.

description: A novel low-cost QFN (Quad Flat Non-Leaded) package is introduced for GaAs MMIC packaging.  The air-cavity QFN package is designed and implemented with an HTCC process using Alumina substrate. To operate the package up to 40 GHz, several key methods are proposed in this paper. A low noise and a buffer amplifier are packaged for practical application examples and compared with bare die measurements to verify the QFN package performance.  A maximum of 4.5 dB insertion loss degradation occurred at 40 GHz.  To authors’ knowledge, this is the highest operating frequency for QFN type packages with low loss ever reported.

description: In this work, we redefined two important statistics, the CLRT test (Bai et.al., Ann. Stat. 37 (2009) 3822-3840) and the LW test (Ledoit and Wolf, Ann. Stat. 30 (2002) 1081-1102) on identity tests for high dimensional data using random matrix theories. Compared with existing CLRT and LW tests, the new tests can accommodate data which has unknown means and non-Gaussian distributions. Simulations demonstrate that the new tests have good properties in terms of size and power. What is more, even for Gaussian data, our new tests perform favorably in comparison to existing tests. Finally, we find the CLRT is more sensitive to eigenvalues less than 1 while the LW test has more advantages in relation to detecting eigenvalues larger than 1.

description: Hintergrund: Ziel der Arbeit ist es, aktuelle Daten zur Inanspruchnahme gesundheitlicher Versorgung in der Schwangerschaft in Deutschland zu erheben und Einflussfaktoren darauf zu identifizieren, um so einen Beitrag zur Erreichung einer bedarfsgerechten Nutzung gesundheitlicher Leistungen während der Schwangerschaft leisten zu können. Methoden: Die Daten stammen aus der KUNO Kids Gesundheitsstudie mit einer Stichprobe von 1886 teilnehmenden Müttern. Die Analysen basieren auf Andersens Verhaltensmodell zur Nutzung des Gesundheitssystems, das zwischen prädisponierenden, ermöglichenden und Bedarfsfaktoren unterscheidet. Ergebnisse: Im Durchschnitt bestehen fünf ambulante Arztbesuche, ein Hausarzt- und vier Facharztkontakte. Ein Fünftel nimmt keine zusätzliche pränatale Diagnostik in Anspruch und in acht Prozent kommt es während der Schwangerschaft zu einer Hospitalisierung. In den Analysen zeigt sich die Bedeutung von Bedarfsfaktoren als Prädiktoren für die Nutzung des Gesundheitssystems. Darüber hinaus gehen eine höhere Gesundheitskompetenz und Multiparität konsistent mit einer geringeren Inanspruchnahme ambulanter, haus- und fachärztlicher Versorgung einher. Zusätzlich erweisen sich die prädisponierenden Faktoren Herkunft, Bildung, Rauchverhalten, körperliche Aktivität oder ungesunde Ernährung, sowie der ermöglichende Faktor soziale Unterstützung als wichtige Einflussgrößen der Inanspruchnahme. Schlussfolgerung: Insgesamt stellen sich Bedarfsfaktoren als bedeutendste Prädiktoren der Inanspruchnahme heraus, gerade im Bereich präventiver Leistungen spielen jedoch prädisponierende und ermöglichende Faktoren eine entscheidende Rolle. Die Variable Gesundheitskompetenz stellt als Mediatorvariable einen möglichen Ansatz zur Reduktion sozialer Ungleichheiten in der Inanspruchnahme gesundheitlicher Versorgung dar.

description: We show that the dipole-dipole coupling between Wannier modes in cigar-shaped Bose-Einstein condensates (BECs) is significantly enhanced while the short-range coupling strongly suppressed. As a result, the dipole-dipole interaction can become the dominant interaction between ultracold alkali Bose atoms. In the long length limit of a cigar-shaped BEC, the resulting effective one-dimensional models possess an effective inverse squared interacting potential, the Calogero-Sutherland potential, which plays a fundamental role in many fields of contemporary physics; but its direct experimental realization has been a challenge for a long time. We propose to realize the Calogero-Sutherland model in ultracold alkali Bose atoms and study the effects of the dipole-dipole interaction.

description: In dieser Studie wurde der Einfluss eines neuen Implantates für das Kniegelenk (Atlas Knee System®) auf die SPECT/CT Untersuchung untersucht. Aufgrund der Materialeigenschaften des Implantats entsteht im CT ein Metallartefakt. Der Einfluss des Metallartefakts im CT auf die quantitative SPECT-Bildgebung wurde für das spezielle Prothesendesign systematisch analysiert. Durch Variation von Aufnahmeparametern des Low Dose CT (LD-CT) und der Anwendung verschiedener Rekonstruktionsalgorithmen konnte die statistische Auswertung von ROIs ein geeignetes Protokollsetup identifizieren. Als Optimierungskriterium galt dabei eine möglichst geringe Strahlenexposition durch das LD-CT und eine Minimierung der Beeinflussung der quantitativen SPECT-Ergebnisse. Das optimierte Scan-Protokoll liefert reproduzierbare Ergebnisse mit den geringsten Abweichungen der Aktivitätskonzentration in den assoziierten Gelenkbereichen (Femur- und Tibia) im Vergleich zur Referenzregion. Die mittlere Unterschätzung der Aktivitätswerte im Femurvolumen betrug bei diesen Protokollen ≤ 10%. Die Studie hat gezeigt, dass das Metallartefakt in der LD-CT einen signifikanten Einfluss auf die Ergebnisse der quantitativen SPECT hat. Dieser Effekt ist insbesondere bei der Interpretation der SPECT-Bilder in bestimmten klinischen Szenarien, z. B. bei der Verlaufskontrolle des Knochenumbaus nach der Prothesenimplantation oder bei der Entscheidung hinsichtlich eines Prothesenwechsels zu beachten.

Relation between Wigner energy and proton-neutron pairing

description: The linear term proportional to $|N-Z|$ in the nuclear symmetry energy (Wigner energy)is obtained in a model that uses isovector pairing on single particle levels from a deformed potential combined with a $\vec T^2$ interaction. The pairing correlations are calculated by numerical diagonalization of the pairing Hamiltonian acting on the six or seven levels nearest the $N=Z$ Fermi surface. The experimental binding energies of nuclei with $N\approx Z$ are well reproduced. The Wigner energy emerges as a consequence of restoring isospin symmetry. We have found the Wigner energy to be insensitive to the presence of moderate isoscalar pair correlations.

Educators engaging in philosophical conversational spaces : participatory action research as a model for initiating change
Creators: name: McDonald, Gavin Dean
Publisher: name: University of British Columbia
Year: 2014

description: This study examined the impact that the establishment of a philosophical conversational space would have on a group of participants and their school context. Specifically, the research questions focused on what effects this participation would have in terms of motivation and morale, sense of professional community, and also its effect upon teaching practice in the classroom. In addition, the study sought to determine in what ways educational institutions can be recreated to include meaningful spaces for philosophical inquiry and critique. This study is informed by critical theory and thus views research as an opportunity to critically analyze the ways in which educational institutions function. Using participatory action research as a methodological foundation for the study allowed participants to play an integral role within the research project. Several themes emerged from the research. The first theme highlighted the importance of the diversity of the group and the sense of community that developed through the study. The second theme identified the importance of using philosophical texts to initiate critical reflection and the interrogation of each participant’s teaching experiences within the school while inspiring possibilities for change. The third important factor to emerge was the way in which participatory action research facilitated the creation of a space in which participants experienced a sense of agency while working together to develop an action plan within the context of their school community. The research suggests there is great value in the creation of conversational spaces that utilize the resources of educational philosophy. It also highlights how participatory action research can be a valuable vehicle in the development and initiation of such spaces in which participants can experience a greater sense of agency as they pursue opportunities for personal growth and institutional transformation.

Effect of nonhomogenous dielectric background on the plasmon modes in graphene double-layer structures at finite temperatures

description: We have calculated the plasmon modes in graphene double layer structures at finite temperatures, taking into account the inhomogeneity of the dielectric background of the system. The effective dielectric function is obtained from the solution of the Poisson equation of three-layer dielectric medium with the graphene sheets located at the interfaces, separating the different materials. Due to the momentum dispersion of the effective dielectric function, the intra- and inter-layer bare Coulomb interactions in the graphene double layer system acquires an additional momentum dependence--an effect that is of the order of the inter-layer interaction itself. We show that the energies of the in-phase and out-of-phase plasmon modes are determined largely by different values of the spatially dependent effective dielectric function. The effect of the dielectric inhomogeneity increases with temperature and even at high temperatures the energy shift induced by the dielectric inhomogeneity and temperature itself remains larger than the broadening of the plasmon energy dispersions due to the Landau damping. The obtained new features of the plasmon dispersions can be observed in frictional drag measurements and in inelastic light scattering and electron energy-loss spectroscopies.

description: We explore the physics potential of multi-megaton scale ice or water Cherenkov detectors with low ($\sim 1$ GeV) threshold. Using some proposed characteristics of the PINGU detector setup we compute the distributions of events versus neutrino energy $E_ν$ and zenith angle $θ_z$, and study their dependence on yet unknown neutrino parameters. The $(E_ν- θ_z)$ regions are identified where the distributions have the highest sensitivity to the neutrino mass hierarchy, to the deviation of the 2-3 mixing from the maximal one and to the CP-phase. We evaluate significance of the measurements of the neutrino parameters and explore dependence of this significance on the accuracy of reconstruction of the neutrino energy and direction. The effect of degeneracy of the parameters on the sensitivities is also discussed. We estimate the characteristics of future detectors (energy and angle resolution, volume, etc.) required for establishing the neutrino mass hierarchy with high confidence level. We find that the hierarchy can be identified at $3σ$ -- $10σ$ level (depending on the reconstruction accuracies) after 5 years of PINGU operation.

Year: 2012

description: We consider unicellular maps, or polygon gluings, of fixed genus. A few years ago the first author gave a recursive bijection transforming unicellular maps into trees, explaining the presence of Catalan numbers in counting formulas for these objects. In this paper, we give another bijection that explicitly describes the "recursive part" of the first bijection. As a result we obtain a very simple description of unicellular maps as pairs made by a plane tree and a permutation-like structure. All the previously known formulas follow as an immediate corollary or easy exercise, thus giving a bijective proof for each of them, in a unified way. For some of these formulas, this is the first bijective proof, e.g. the Harer-Zagier recurrence formula, the Lehman-Walsh formula and the Goupil-Schaeffer formula. We also discuss several applications of our construction: we obtain a new proof of an identity related to covered maps due to Bernardi and the first author, and thanks to previous work of the second author, we give a new expression for Stanley character polynomials, which evaluate irreducible characters of the symmetric group. Finally, we show that our techniques apply partially to unicellular 3-constellations and to related objects that we call quasi-constellations.

Forced tearing of ductile and brittle thin sheets

Publisher: name: arXiv
Year: 2011
Subjects: subject: Materials Science (cond-mat.mtrl-sci)

description: Tearing a thin sheet by forcing a rigid object through it leads to complex crack morphologies; a single oscillatory crack arises when a tool is driven laterally through a brittle sheet, while two diverging cracks and a series of concertina-like folds forms when a tool is forced laterally through a ductile sheet. On the other hand, forcing an object perpendicularly through the sheet leads to radial petal-like tears in both ductile and brittle materials. To understand these different regimes we use a combination of experiments, simulations and simple theories. In particular, we describe the transition from brittle oscillatory tearing via a single crack to ductile concertina tearing with two tears by deriving laws that describe the crack paths and wavelength of the concertina folds and provide a simple phase diagram for the morphologies in terms of the material properties of the sheet and the relative size of the tool.

description: Traditional quantum physics solves ground states for a given Hamiltonian, while quantum information science asks for the existence and construction of certain Hamiltonians for given ground states. In practical situations, one would be mainly interested in local Hamiltonians with certain interaction patterns, such as nearest neighbour interactions on some type of lattices. A necessary condition for a space $V$ to be the ground-state space of some local Hamiltonian with a given interaction pattern, is that the maximally mixed state supported on $V$ is uniquely determined by its reduced density matrices associated with the given pattern, based on the principle of maximum entropy. However, it is unclear whether this condition is in general also sufficient. We examine the situations for the existence of such a local Hamiltonian to have $V$ satisfying the necessary condition mentioned above as its ground-state space, by linking to faces of the convex body of the local reduced states. We further discuss some methods for constructing the corresponding local Hamiltonians with given interaction patterns, mainly from physical points of view, including constructions related to perturbation methods, local frustration-free Hamiltonians, as well as thermodynamical ensembles.

The virtualization of free space and action : advancing a mondernized model of power inequity attenuation and the Free Space Index (FSIx)
Creators: name: Turner, Roger Anthony
Publisher: name: University of British Columbia
Year: 2014

description: Although international electronic technologies have not provided a direct portal to a Utopian world of fairness and equality as some had dreamed, they have important implications for socio-organizational power that have thus far been under-considered. Once a power structure is in place, it is generally self-reinforcing — powerful actors have motivation and wherewithal to subordinate others, and less powerful actors are constrained from resisting. However, when a technology is introduced to a social system, it creates opportunities for interaction patterns governing power within that system to evolve. International electronic technologies create new and rapidly changing, virtualized contexts for computer mediated communication, social media broadcasting, social networking, coordination, and action. These contexts erode geographic, social, and psychological boundaries that have traditionally determined how, and if, power would be utilized, accepted, resisted, or challenged. In this dissertation I present a modernized model of power that takes these changes into account and report six related empirical studies. In advancing my model, I also draw from, refine, and extend free space theory. I argue that these technologies embed sheltered interaction contexts where the less powerful can express themselves and interact more freely. These spaces can spawn social movements and other forms of collective resistance and ultimately result in social- and/or organizational change. In Studies 1-3, I create the Free Space Index to identify such spaces both online and offline. I collect data in Canada, the USA, and Denmark for cross-societal validation. Studies 4-6 test two central propositions underling my model. The first is that electronic technologies discourage some power-reinforcing behaviours by raising perceived retribution risks; Study 4 examines this in an organizational decision-making context. The second is that these technologies promote action challenging prevailing power structures. Study 5 shows the effect of self-interest, a key offline action predictor, differs online. Study 6 demonstrates that electronic technologies promote action by reducing participation costs—congruent with the slacktivism moniker often applied to Internet mediated social activism—but also by attenuating a number of socio-psychological constraints that discourage offline action. I discuss the implications and limitations of my model and empirical work and suggest future research directions.

description: Norms of cooperation and punishment differ across societies, but also within a single society. In an experiment with two subject pools sharing the same geographical and cultural origins, we show that opportunities for peer punishment increase cooperation among students but not in the general population. In previous studies, punishment magnified the differences across societies in peoples ability to cooperate. Here, punishment reversed the order: with punishment, students cooperate more than the general population while they cooperate less without it. Our results obtained with students cannot be readily generalized to the society at large.

Methode: Es wurden schizophreniespezifische, induziert pluripotente Stammzellen (iPS-Zellen) mit einer Kopienzahlvariation (CNV) in NRXN1 sowie iPS-Zellen psychiatrisch gesunder Spender durch ein in vitro Modell zu einer neuronalen Kultur differenziert und im Anschluss mittels PCR, Immunfluoreszenz sowie Durchflusszytometrie analysiert. Ergebnis: Die neuronale Differenzierung wurde durch den Nachweis verschiedener Marker gezeigt. Die Präsenz glialer Zellen sowie neuronaler Subtypen wurde durch die Expressionsanalyse gezeigt und via Durchflusszytometrie quantifiziert. Es wurden keine Unterschiede zwischen den NRXN1-CNV-Zelllinien und den iPS-Zellen psychiatrisch gesunder Spender festgestellt.

Methods: Schizophrenia-specific induced pluripotent stem cells (iPS cells) with a copy number variation (CNV) in NRXN1 as well as iPS cells from psychiatrically healthy donors were differentiated into a neuronal culture by an in vitro model and subsequently analyzed by reverse transcriptase-PCR, immunofluorescence as well as flow cytometry. Results: Neuronal differentiation was demonstrated by the detection of various markers. The presence of glial cells as well as neuronal subtypes was shown by expression analysis and quantified via flow cytometry. No differences were found between the NRXN1-CNV cell lines and iPS cells from psychiatrically healthy donors. Conclusion: The model used provides an important basis for studying DNA variations in NRXN1.

description: We show how a theorem of Gabber on alterations can be used to apply work of Cisinski, Suslin, Voevodsky, and Weibel to prove that $K_n(X)[1/p] = 0$ for $n < - \dim X$ where $X$ is a quasi-excellent noetherian scheme, $p$ is a prime that is nilpotent on $X$, and $K_n$ is the $K$-theory of Bass-Thomason-Trobaugh. This gives a partial answer to a question of Weibel.

description: A new language for epistemic logic is introduced in which the epis-
temic operators are of the form j x : x1 : : : xnj with the intended read-
ing
\x knows of x1 : : : xn that ...".
Analogously we can express \t knows of t1 : : : tn that ... ", where
t; t1 : : : tn are terms. An advantage of this approach is that we can
quantify on the agents, \every y knows of x1 : : : xn that A" or \some
expert knows of t1 : : : tn that A" can easily be expressed. The semantics we present for this language is a generalization of the transition semantics, called epistemic transition semantics in which the possible worlds are states of affairs compatible with the epistemic state of some agent. A calculus is presented and shown to be complete with respect to epistemic transition semantics.

description: In this thesis, we address several problems in active and sequential learning. Using the frameworks of the stochastic multi-armed bandit problem and nonparametric statistics, we make several contributions in active learning and zeroth order stochastic optimization. We are particularly interested in the problem of designing adaptive algorithmic strategies, in the sense that they do not require the careful tuning of parameters that are out of reach for practitioners. This is particularly important in the context of active sequential learning, as the careful selection of which data to label, in the abundance of unlabeled data, depends on these tuning parameters. Therefore, sub-optimal learning may incur avoidable labeling costs or lead to poor performance. In some settings, we design such adaptive algorithms and show their optimality. In others, we prove impossibility theorems that preclude their existence.
description: In dieser Dissertation beschäftigen wir uns mit verschiedenen Problemen des aktiven und sequentiellen Maschinenlernens. Unter Verwendung der Rahmenbedingungen des stochastischen mehrarmigen Banditenproblems und der nichtparametrischen Statistik leisten wir verschiedene Beiträge zum aktiven Lernen und zur stochastischen Optimierung nullter Ordnung. Wir sind besonders an dem Problem interessiert, adaptive algorithmische Strategien zu entwerfen, in dem Sinne, dass sie keine sorgfältige Abstimmung von Parametern erfordern, die für Praktiker unerreichbar sind. Dies ist besonders wichtig im Zusammenhang mit aktivem sequentiellem Lernen, da die sorgfältige Auswahl der zu kennzeichnenden Daten in der Fülle nicht beschrifteter Daten von diesen Abstimmungsparametern abhängen kann. Daher kann suboptimales Lernen vermeidbare Kennzeichnungskosten verursachen oder zu einer schlechten Leistung führen. In einigen Einstellungen entwerfen wir solche adaptiven Algorithmen und zeigen ihre Optimalität. In anderen beweisen wir Unmöglichkeitssätze, die ihre Existenz ausschließen.

description: We present a measurement protocol for discriminating between two different quantum states of a qubit with high fidelity. The protocol, called null value, is comprised of a projective measurement performed on the system with a small probability (also known as partial-collapse), followed by a tuned postselection. We report on an optical experimental implementation of the scheme. We show that our protocol leads to an amplified signal-to-noise ratio (as compared with a straightforward strong measurement) when discerning between the two quantum states.

Die Bedeutung der cerebro-plazentaren Ratio für die Prognose des neonatalen Outcomes

description: Der dopplersonografische Parameter cerebro-plazentare Ratio (CPR) gibt Auskunft über die fetale Hämodynamik bzw. die Umverteilung des fetalen Blutvolumens als Reaktion auf eine metabolische Veränderung innerhalb der Schwangerschaft. In der vorliegenden Dissertation wurde ermittelt, inwieweit die CPR als valider Parameter in der routinemäßigen geburtshilflichen Untersuchung genutzt werden kann. Es wurde sowohl bei altersgemäß entwickelten (Appropriate for Gestational Age, AGA) als auch bei zu klein entwickelten (Small for Gestational Age, SGA) Feten untersucht, ob die CPR zur Einschätzung des neonatalen Outcomes dienen kann. Diesbezüglich erfolgte zudem ein Vergleich mit dem fetalen Schätzgewicht sowie der Kardiotokografie (CTG). Dazu wurden drei Hypothesen auf Basis von retrospektiv erhobenen Daten geprüft. Das untersuchte Patientenkollektiv bestand aus 800 von insgesamt 1.739 Schwangerschaften, die in den Jahren 2016 und 2017 im Rahmen der Intensivschwangerenberatung der Universitätsfrauenklinik Magdeburg betreut wurden. Im Ergebnis zeigt sich die CPR in der Prädiktion des neonatalen Outcomes vergleichbar mit dem fetalen Schätzgewicht und präziser als das CTG. Außerdem ist eine abnormale CPR < 1,08 bei AGA-Feten mit einer erhöhten Sectiorate aufgrund fetalen Distresses sowie einem schlechten neonatalen Outcome assoziiert. In der Gruppe der SGA-Feten konnten keine signifikanten Zusammenhänge einer abnormal niedrigen CPR mit einer erhöhten Sectiorate bzw. einem schlechten neonatalen Outcome festgestellt werden. Die CPR kann zukünftig insbesondere bei AGA-Feten im Rahmen des pränatalen Screenings zur Optimierung der fetalen Zustandsdiagnostik sowie zur zuverlässigen Planung eines geeigneten Geburtsmanagements beitragen.

description: Charge transport through a small topological superconducting island in contact with a normal and a superconducting electrode occurs through a cycle that involves coherent oscillations of Cooper pairs and tunneling in/out the normal electrode through a Majorana bound state, the Josephson-Majorana cycle. We illustrate this mechanism by studying the current-voltage characteristics of a superconductor-topological superconductor-normal metal single-electron transistor. At low bias and temperature the Josephson-Majorana cycle is the dominant mechanism for transport. We discuss a three-terminal configuration where the non-local character of the Majorana bound states is emergent.

Probing High-Scale and Split Supersymmetry with Higgs Mass Measurements

description: We study the range of Higgs masses predicted by High-Scale Supersymmetry and by Split Supersymmetry, using the matching condition for the Higgs quartic coupling determined by the minimal field content. In the case of Split Supersymmetry, we compute for the first time the complete next-to-leading order corrections, including two-loop renormalization group equations and one loop threshold effects. These corrections reduce the predicted Higgs mass by a few GeV. We investigate the impact of the recent LHC Higgs searches on the scale of supersymmetry breaking. In particular, we show that an upper bound of 127 GeV on the Higgs mass implies an upper bound on the scale of Split Supersymmetry of about 10^8 GeV, while no firm conclusion can yet be drawn for High-Scale Supersymmetry.
