description: The highly dynamical, complex nature of the solar atmosphere naturally implies the presence of waves in a topologically varied magnetic environment. Here, the interaction of waves with topological features such as null points is inevitable and potentially important for energetics. The low resistivity of the solar coronal plasma implies that non-MHD effects should be considered in studies of magnetic energy release in this environment. This paper investigates the role of the Hall term in the propagation and dissipation of waves, their interaction with 2D magnetic X-points and the nature of the resulting reconnection. A Lagrangian remap shock-capturing code (Lare2d) is used to study the evolution of an initial fast magnetoacoustic wave annulus for a range of values of the ion skin depth in resistive Hall MHD. A magnetic null-point finding algorithm is also used to locate and track the evolution of the multiple null-points that are formed in the system. Depending on the ratio of ion skin depth to system size, our model demonstrates that Hall effects can play a key role in the wave-null interaction. In particular, the initial fast-wave pulse now consists of whistler and ion-cyclotron components; the dispersive nature of the whistler wave leads to (i) earlier interaction with the null, (ii) the creation of multiple additional, transient nulls and, hence, an increased number of energy release sites. In the Hall regime, the relevant timescales (such as the onset of reconnection and the period of the oscillatory relaxation) of the system are reduced significantly, and the reconnection rate is enhanced.

description: Die Zahl der Privatschüler*innen steigt in Deutschland stetig, insbesondere in Ostdeutschland. Besonders häufig kommen sie aus Haushalten mit hohem Einkommen und hohem Bildungsniveau. Dieser Wochenbericht untersucht, welche Rolle die räumliche Verteilung von Privatschulen für die Struktur der Schüler*innenschaft spielt. In einem ersten Schritt wird untersucht, in welchen Gegenden es Privatschulen gibt. Dabei zeigt sich, dass Privatschulen in Ostdeutschland geografisch breiter und zufälliger verteilt sind als in Westdeutschland – es gibt sie also nicht nur dort, wo vor allem privilegierte Haushalte wohnen. In einem zweiten Schritt wird untersucht, ob die geografische Nähe zu einer Privatschule den Besuch selbiger wahrscheinlicher macht. Es zeigt sich, dass das bei einkommensstarken und bildungsnahen Haushalten der Fall ist. Einkommensschwache und bildungsferne Haushalte schicken ihre Kinder hingegen auch dann nicht häufiger auf eine Privatschule, wenn sie in deren Nähe wohnen. Offenbar stellen private Schulen für sie meistens keine Alternative dar. Wie weitere Analysen zeigen, ist dies auch, aber nicht allein durch das Schulgeld zu erklären. Nötig sind daher unter anderem zugänglichere Informationen über Privatschulen. Diese könnten stärker öffentlich gefördert werden – letztlich müssen aber auch öffentliche Schulen für privilegierte Haushalte attraktiver werden, um soziale Unterschiede mit Blick auf die Schulwahl zu reduzieren.

description: We update the determination of the isovector nucleon electromagnetic self-energy, valid to leading order in QED. A technical oversight in the literature concerning the elastic contribution to Cottingham's formula is corrected and modern knowledge of the structure functions is used to precisely determine the inelastic contribution. We find δM_{p-n}^γ= 1.30(03)(47) MeV. The largest uncertainty arises from a subtraction term required in the dispersive analysis, which can be related to the isovector magnetic polarizability. With plausible model assumptions, we can combine our calculation with additional input from lattice QCD to constrain this polarizability as: β_{p-n} = -0.87(85) x 10^{-4} fm^3.

description: Solutions of geodesic equations describing propagation of gravitons in the bulk are studied in a cosmological model with one extra dimension. Brane with matter is embedded in the bulk. It is shown that in the period of early cosmology gravitons emitted from the brane to the bulk under certain conditions can return back to the brane. The model is discussed in two alternative approaches: (i) brane with static metric moving in the AdS space, and (ii) brane located at a fixed position in extra dimension with non-static metric. Transformation of coordinates from the one picture to another is performed. In both approaches conditions for gravitons emitted to the bulk to come back to the brane are found.

description: In this article, we investigate the competitive interaction between electrical vehicles or hybrid oil-electricity vehicles in a Cournot market consisting of electricity transactions to or from an underlying electricity distribution network. We provide a mean field game formulation for this competition, and introduce the set of fundamental differential equations ruling the behavior of the vehicles at the feedback Nash equilibrium, referred here to as the mean field equilibrium. This framework allows for a consistent analysis of the evolution of the price of electricity as well as of the instantaneous electricity demand in the power grid. Simulations precisely quantify those parameters and suggest that significant reduction of the daily electricity peak demand can be achieved by appropriate electricity pricing.

description: Bei der Versorgung mit Rohstoffen hängt die deutsche Volkswirtschaft zu über 90 Prozent von Importen ab. Viele dieser Rohstoffimporte stammen aus nur wenigen Förderländern. Häufig sind diese Länder wenig demokratisch verfasst. Insofern sind die Lieferrisiken teilweise extrem hoch, auch bei mineralischen Rohstoffen, darunter Seltene Erden, Lithium und Magnesium. Um die Sicherheit von Rohstoffimporten zu erhöhen, kann die Wirtschaftspolitik verschiedene Maßnahmen ergreifen. So könnten europäische Abnehmer ihre Beschaffung kritischer Rohstoffe bündeln, um der Marktmacht der wenigen Anbieter etwas entgegen zu setzen. Ferner könnten noch weitere Diversifizierungspotenziale beim Import genutzt werden. Auch die Lagerhaltung sollte überdacht und um eine verpflichtende Mindestreserve ergänzt werden. Längerfristig könnten Rohstoffimporte reduziert werden, indem Möglichkeiten zum Recycling stärker genutzt werden und die Förderung von mineralischen Rohstoffen im Inland ausgebaut wird. Schließlich sollten technische Innovationen angestoßen werden, um Einfuhren von Rohstoffen zu ersetzen. Die Maßnahmen sollten – soweit möglich – auf europäischer Ebene koordiniert werden.

Translocation and accumulation of organic and inorganic nitrogen in wood resources colonized by the mycelial cord systems of the decay fungus Hypholoma fasciculare
Creators: name: Philpott, Timothy James
Publisher: name: University of British Columbia
Year: 2012

description: Translocation of nitrogen (N) through mycelial cords of wood decay fungi is thought to be the mechanism responsible for the observed increase in absolute N content in woody debris over time. This research evaluates the ability of the mycelial cords of the wood ¹⁵decay fungus Hypholoma fasciculare to translocate and accumulate labeled organic (¹⁵N-glycine, N Douglas-fir litter) and inorganic N (¹⁵NH₄⁺, ¹⁵NO₃⁻) in its wood substrate. Each N form was supplied separately to the growing fronts of mycelial cords established over 67 days from wood blocks (Douglas-fir) in soil microcosms. Three sampling occasions (days 6, 18 and 30 after N addition) were used to identify trends in ¹⁵N transfer and total N accumulation. Wood blocks inoculated with Hypholoma fasciculare assimilated significantly more ¹⁵N than uninoculated blocks for all ¹⁵N treatments on at least one sampling occasion. After 73 days of incubation (day 6 sampling occasion), inoculated wood blocks increased in absolute N content by 211% relative to uninoculated control blocks, but 80% of this accumulated N was lost after 97 days of incubation (day 30 sampling occasion). The small amount of ¹⁵N that was transferred contrasted with the large increase in total N, suggesting that the site of N transfer was largely from the soil underneath wood blocks rather than at the site of ¹⁵N injection. The precipitous decline in absolute N content was attributed to visible indications of mycelial senescence. This research demonstrates that the mycelial cords of Hypoloma fasciculare are capable of translocating ¹⁵N into a wood substrate and can also greatly increase the absolute N content of wood blocks. The results are discussed in the context of fungal ecology as well as woody debris management.

description: We study a new notion of Ricci curvature that applies to Markov chains on discrete spaces. This notion relies on geodesic convexity of the entropy and is analogous to the one introduced by Lott, Sturm, and Villani for geodesic measure spaces. In order to apply to the discrete setting, the role of the Wasserstein metric is taken over by a different metric, having the property that continuous time Markov chains are gradient flows of the entropy. Using this notion of Ricci curvature we prove discrete analogues of fundamental results by Bakry--Emery and Otto--Villani. Furthermore we show that Ricci curvature bounds are preserved under tensorisation. As a special case we obtain the sharp Ricci curvature lower bound for the discrete hypercube.

description: Complementarity principle is one of the central concepts in quantum mechanics which restricts joint measurement for certain observables. Of course, later development shows that joint measurement could be possible for such observables with the introduction of a certain degree of unsharpness or fuzziness in the measurement. In this paper, we show that the optimal degree of unsharpness, which guarantees the joint measurement of all possible pairs of dichotomic observables, determines the degree of nonlocality in quantum mechanics as well as in more general no-signaling theories.

description: Various fundamental phenomena of strongly-correlated quantum systems such as high-$T_c$ superconductivity, the fractional quantum-Hall effect, and quark confinement are still awaiting a universally accepted explanation. The main obstacle is the computational complexity of solving even the most simplified theoretical models that are designed to capture the relevant quantum correlations of the many-body system of interest. In his seminal 1982 paper [Int. J. Theor. Phys. 21, 467], Richard Feynman suggested that such models might be solved by "simulation" with a new type of computer whose constituent parts are effectively governed by a desired quantum many-body dynamics. Measurements on this engineered machine, now known as a "quantum simulator," would reveal some unknown or difficult to compute properties of a model of interest. We argue that a useful quantum simulator must satisfy four conditions: relevance, controllability, reliability, and efficiency. We review the current state of the art of digital and analog quantum simulators. Whereas so far the majority of the focus, both theoretically and experimentally, has been on controllability of relevant models, we emphasize here the need for a careful analysis of reliability and efficiency in the presence of imperfections. We discuss how disorder and noise can impact these conditions, and illustrate our concerns with novel numerical simulations of a paradigmatic example: a disordered quantum spin chain governed by the Ising model in a transverse magnetic field. We find that disorder can decrease the reliability of an analog quantum simulator of this model, although large errors in local observables are introduced only for strong levels of disorder. We conclude that the answer to the question "Can we trust quantum simulators?" is... to some extent.

Deep Crustal Heating in a Multicomponent Accreted Neutron Star Crust

description: A quasi-statistical equilibrium model is constructed to simulate the multicomponent composition of the crust of an accreting neutron star. The ashes of rp-process nucleosynthesis are driven by accretion through a series of electron captures, neutron emissions, and pycnonuclear fusions up to densities near the transition between the neutron star crust and core. A liquid droplet model which includes nuclear shell effects is used to provide nuclear masses far from stability. Reaction pathways are determined consistently with the nuclear mass model. The nuclear symmetry energy is an important uncertainty in the masses of the exotic nuclei in the inner crust and varying the symmetry energy changes the amount of deep crustal heating by as much as a factor of two.

description: A general partial-wave multiple scattering theory for scattering from cylindrically symmetric potentials on a topological insulator (TI) surface is developed. As an application, the cross sections for a single scatterer and two scatterers are discussed. We find that the symmetry of differential cross section is reduced and the backscattering is allowed for massive Dirac fermions on gapped TI surface. Remarkably, a sharp resonance peak at the band edge of the gapped TI is found in the total cross section $Λ_{tot}$, which may offer a useful way to determine the gap (as well as the effective mass of quasiparticles) on TI surface. We show that the interference effect is obvious in cross sections during the quasiparticle scattering between the scatterer pair, and additional resonance peaks are introduced in $Λ_{tot}$ when the higher partial waves are taken into account.

description: Die Effekte der Klimakrise verschärfen die Wasserknappheit nicht nur im globalen Süden, sondern auch in unseren Breitengraden, beispielsweise in der Region Berlin-Brandenburg. Wegen unzureichender Bepreisung der Entnahme von Oberflächen- und Grundwasser beziehungsweise mangelnden ordnungsrechtlichen Instrumenten kommt es in einigen Regionen Deutschlands zu einem Überverbrauch. Dies ist insbesondere in der Industrie der Fall, die sich hohe Wasserentnahmemengen zu sehr geringen Kosten vertraglich gesichert hat. Dazu kommt eine umfangreiche Gewässerverschmutzung durch Schadstoffeinträge aus Haushalten, Industrie, Kläranlagen und Landwirtschaft, die das Angebot an sauberem Wasser weiter verknappen. Insbesondere die Nitratverschmutzung aufgrund intensiver Düngung in der Landwirtschaft stellt ein zunehmendes Problem dar. In der Folge entstehen zusätzliche Kosten für Unternehmen und Haushalte zum Beispiel durch aufwendigere Trinkwasseraufbereitung. Ökolandbau kann hier die Gewässerqualität verbessern; auch sanitäre Innovationen (wie Trockentrenntoiletten) können einen Beitrag leisten. Dieser Wochenbericht fasst aktuelle Forschungsergebnisse zusammen und leistet einen Beitrag zur Nationalen Wasserstrategie der Bundesregierung, die ein Programm von Maßnahmen vorsieht, die bis zum Jahr 2030 zur Bewältigung der Generationenaufgabe Wasser ergriffen werden sollen.

description: Time delay in galaxy gravitational lensing systems has been used to determine the value of Hubble constant. As in other dynamical phenomena at the scale of galaxy, dark matter is often invoked in gravitational lensing to account for the "missing mass" (the apparent discrepancy between the dynamical mass and the luminous mass). Alternatively, modified gravity can be used to explain the discrepancy. In this paper we adopt the Tensor-Vector-Scalar gravity (TeVeS), a relativistic version of MOdified Newtonian Dynamics (MOND), to study gravitational lensing phenomena and derive the formulae needed to evaluate the Hubble constant. We test our method on quasar lensing by elliptical galaxies in the literature. We focus on double-image systems with time delay measurement. Three candidates are suitable for our study: HE 2149-2745, FBQ J0951+2635 and SBS 0909+532. The Hubble constant obtained is consistent with the value used in fitting the CMB result in neutrino cosmological model.

E-cadherin regulation in ovarian cancer: mechanisms and potential functional roles
Creators: name: Lau, Man Tat
Publisher: name: University of British Columbia

description: E-cadherin is a cell-cell adhesion protein and tumor suppressor that is silenced in many malignancies. However, the role of E-cadherin in ovarian cancer progression is still controversial. In an attempt to define the regulation of E-cadherin in ovarian cancer, we found that local growth factors, FGF2 and IGF1, suppress E-cadherin expression in ovarian cancer cells. To elucidate the role of E-cadherin in ovarian cancer progression, we found that stable knockdown of E-cadherin significantly enhances, whereas overexpression of E-cadherin reduces tumor cell growth and invasion. Loss of E-cadherin results in constitutive activation of phosphoinositide 3-kinase (PI3K)/Akt signaling by inhibition of PTEN transcription through downregulation of Egr1. In addition, immunofluorescence microscopy and TCF promoter/luciferase reporter assays showed that E-cadherin loss was associated with enhanced nuclear beta-catenin signaling. Constitutive activation of PI3K/Akt signaling reinforced nuclear beta-catenin signaling by inactivating glycogen synthase kinase-3beta indicating cross talk between the PI3K/Akt and beta-catenin signaling pathways. Furthermore, we found that E-cadherin negatively regulates tumor cell growth, in part, by positively regulating PTEN expression via beta-catenin-mediated Egr1 regulation, thus influencing PI3K/Akt signaling. Finally, the constitutive activation of PI3K/Akt signaling activates its downstream mammalian target of rapamycin (mTOR) signaling pathway. The pharmacological inhibition of PI3K and mTOR suggests that PI3K/Akt/mTOR is required for E-cadherin-depletion-induced tumor cell motility. Moreover, loss of E-cadherin induces tumor cell invasion, in part, by activation of Rho GTPase, Cdc42 and Rac1. In summary, endogenous E-cadherin inhibits PI3K/Akt signaling and Rho GTPase activation. Thus, the loss of E-cadherin itself may contribute to dysregulate PI3K/Akt signaling and Rho GTPase activation to promote tumor proliferation and invasion in human ovarian cancer cells.

description: The chirally improved (CI) quark propagator in Landau gauge is calculated in two flavor lattice Quantum Chromodynamics. Its wave-function renormalization function $Z(p^2)$ and mass function $M(p^2)$ are studied. To minimize lattice artifacts, tree-level improvement of the propagator and tree-level correction of the lattice dressing functions is applied. Subsequently the CI quark propagator under Dirac operator low-mode removal is investigated. The dynamically generated mass in the infrared domain of the mass function is found to dissolve continuously as a function of the reduction level and strong suppression of $Z(p^2)$ for small momenta is observed.

description: In this work, two different methods for extracting the mass of a new quark from the (pseudo) data are compared: the classical cut-based method and the matrix element method. As a concrete example a fourth family up type quark is searched in p-p collisions of 7 TeV center of mass energy. We have shown that even with very small number of events, Matrix Element Method gives better estimations for the mass value and its error, especially for event samples in which Signal to Background ratio is greater than 0.2.

Community policing in Singapore
Creators: name: Low, Mark Jian Neng
Publisher: name: University of British Columbia
Year: 2012

description: This thesis is devoted towards unpacking how community policing has been managed as a state discourse by the Singapore Police Force. Firstly, community policing is located within the historical context of a modernising Singapore. This begins with the need for crime prevention that was disseminated through decentralised neighbourhood police posts in the 1980s. With economic restructuring in the 1990s, community policing was rescaled to meet the changing demography of the population. Following an enhanced deployment of counter-terrorism discourse in the wake of 9/11, community policing was re-invented as part of a (re)bordering strategy to safeguard territorial sovereignty and social cohesion. Secondly, the methodology of community policing is visualised through the changing frames of the state-produced docu-drama, Crime Watch. As a television programme that has consistently raked in high viewership numbers for 25 years, Crime Watch texts deserve their fair share of critical scrutiny to reveal the means of community engagement by the state police. Thirdly, the personal networks of Volunteer Special Constables are studied for the insights that they can reveal into the work of policing one’s community. Personal interviews with sixteen volunteers provide the empirical data for analysis. Volunteers have committed much time and effort into performing the work of volunteer police officers. Mediating the boundaries between the police and the public, these volunteers translate community policing into practice in complicated ways that have not been adequately documented. In summary this thesis makes three contributions to social geography: it traces the convoluted history of community policing as a state-authored discourse; it sketches the stereotypical plotlines of community policing as a tool for community engagement; and it uncovers the personal networks through which community/policing may be performed.

description: Holevo, Schumacher, and Westmoreland's coding theorem guarantees the existence of codes that are capacity-achieving for the task of sending classical data over a channel with classical inputs and quantum outputs. Although they demonstrated the existence of such codes, their proof does not provide an explicit construction of codes for this task. The aim of the present paper is to fill this gap by constructing near-explicit "polar" codes that are capacity-achieving. The codes exploit the channel polarization phenomenon observed by Arikan for the case of classical channels. Channel polarization is an effect in which one can synthesize a set of channels, by "channel combining" and "channel splitting," in which a fraction of the synthesized channels are perfect for data transmission while the other fraction are completely useless for data transmission, with the good fraction equal to the capacity of the channel. The channel polarization effect then leads to a simple scheme for data transmission: send the information bits through the perfect channels and "frozen" bits through the useless ones. The main technical contributions of the present paper are threefold. First, we leverage several known results from the quantum information literature to demonstrate that the channel polarization effect occurs for channels with classical inputs and quantum outputs. We then construct linear polar codes based on this effect, and the encoding complexity is O(N log N), where N is the blocklength of the code. We also demonstrate that a quantum successive cancellation decoder works well, in the sense that the word error rate decays exponentially with the blocklength of the code. For this last result, we exploit Sen's recent "non-commutative union bound" that holds for a sequence of projectors applied to a quantum state.
