description: We study analytically the dynamic behaviors of quantum correlation measured by quantum discord between two uncoupled qubits, which are immersed in a common Ohmic environment. We show that the quantum discord of the two noninteracting qubits can be greatly amplified or protected for certain initially prepared $X$-type states in the time evolution. Especially, it is found that there does exist the stable amplification of the quantum discord for the case of two identical qubits, and the quantum discord can be protected for the case of two different qubits with a large detuning. It is also indicated that in general there does exist a sudden change of the quantum discord in the time evolution at a critic time point $t_c$, and the discord amplification and protection may occur only in the time interval $0

Deshalb rücken auch elterliche Kompetenzen in den Fokus. Über das fachlich-fachdidaktisches Wissen von Eltern ist derzeit aber kaum etwas bekannt. Mit diesem Thema befasst sich das vorliegende Dissertationsprojekt. Ein erster Schritt ist die Entwicklung eines Vignetten-Instruments zur Erfassung von fachlich-fachdidaktischen elterlichen Kompetenzen, das im Rahmen einer Befragung von Eltern zum Einsatz kommen soll.

description: Noisy linear problems have been studied in various science and engineering disciplines. A class of "hard" noisy linear problems can be formulated as follows: Given a matrix $\hat{A}$ and a vector $\mathbf{b}$ constructed using a finite set of samples, a hidden vector or structure involved in $\mathbf{b}$ is obtained by solving a noise-corrupted linear equation $\hat{A}\mathbf{x} \approx \mathbf{b} + \boldsymbolη$, where $\boldsymbolη$ is a noise vector that cannot be identified. For solving such a noisy linear problem, we consider a quantum algorithm based on a divide-and-conquer strategy, wherein a large core process is divided into smaller subprocesses. The algorithm appropriately reduces both the computational complexities and size of a quantum sample. More specifically, if a quantum computer can access a particular reduced form of the quantum samples, polynomial quantum-sample and time complexities are achieved in the main computation. The size of a quantum sample and its executing system can be reduced, e.g., from exponential to sub-exponential with respect to the problem length, which is better than other results we are aware. We analyse the noise model conditions for such a quantum advantage, and show when the divide-and-conquer strategy can be beneficial for quantum noisy linear problems.

description: In previous work, I have developed an information theoretic complexity measure of networks. When applied to several real world food webs, there is a distinct difference in complexity between the real food web, and randomised control networks obtained by shuffling the network links. One hypothesis is that this complexity surplus represents information captured by the evolutionary process that generated the network. In this paper, I test this idea by applying the same complexity measure to several well-known artificial life models that exhibit ecological networks: Tierra, EcoLab and Webworld. Contrary to what was found in real networks, the artificial life generated foodwebs had little information difference between itself and randomly shuffled versions.

description: We explore the prospects for confining alkaline-earth Rydberg atoms in an optical lattice via optical dressing of the secondary core valence electron. Focussing on the particular case of strontium, we identify experimentally accessible magic wavelengths for simultaneous trapping of ground and Rydberg states. A detailed analysis of relevant loss mechanisms shows that the overall lifetime of such a system is limited only by the spontaneous decay of the Rydberg state, and is not significantly affected by photoionization or autoionization. The van der Waals C_6 coefficients for the 5sns series are calculated, and we find that the interactions are attractive. Finally we show that the combination of magic-wavelength lattices and attractive interactions could be exploited to generate many-body Greenberger-Horne-Zeilinger (GHZ) states.

description: We calculate the cross-section of the near-threshold off-shell $ZZZ$ and $ZW^+W^-$ production at the International Linear Collider taking into account their instability and the principal part of NLO corrections. The calculations are performed in the framework of the model of unstable particles with smeared mass-shell. We show that the contribution of the finite $Z/W$ and $H$ widths (their instability) is large in the Higgs resonance range and should be taken into account in the Higgs boson searches at future colliders.

Design and characterization of an actuator test fixture for diesel fuel injectors
Creators: name: Hossain, Syed Tanjid
Publisher: name: University of British Columbia
Year: 2019

description: The High-Pressure Direct Injection of Natural Gas in a diesel engine is one of the innovative solutions to reduce diesel engine pollutants. The quantity and quality of the fuel injected is highly depended on the spray pattern, which controls the air and NG fuel mixture in the combustion cylinder. Fuel release is regulated by a needle, that is linked to a solenoid actuator through a hydraulic system. An actuator with position feedback can control the spray pattern of a fuel injector by controlling the needle displacement of the injector. However, the relationship between the actuator displacement and injector needle displacement is unknown. Therefore, an Actuator Test Fixture (ATF) is designed that simulates the injection process of a typical hydraulically actuated fuel injector. It allows the researcher to study and ultimately model the relationship between actuator displacement and needle motion. In contrary to conventional fuel injectors, the ATF provides measurement access to all model parameters and allows their characterization. Thus, a characterized model is created that describes the relationship between the actuator displacement and ATF needle motion. The model of the ATF combines both the mechanical aspect of the components and the hydraulic mechanics of the fuel. There are two inputs to this model, the experimentally measured actuator displacement and experimentally measured supply pressure. ATF needle lift and control chamber pressures are the outputs of the model. The experimental-model comparison showed good agreement. The model is verified across several different operating points by varying the supply pressure and the actuator pulse duration to increase confidence in the experimental-model results. At high supply pressure, the model fits very well but as the pressure reduces the model starts to show discrepancy. This is likely due to un-modeled friction effects in the ATF. Nevertheless, the experimental-model control chamber pressures and needle lifts are very similar.

description: Very recently, we have shown how the harmonic analysis approach can be modified to deal with products of general Hermitian and complex random matrices at finite matrix dimension. In the present work, we consider the particular product of a multiplicative Pólya ensemble on the complex square matrices and a Gaussian unitary ensemble (GUE) shifted by a constant multiplicative of the identity. The shift shall show that the limiting hard edge statistics of the product matrix is weakly dependent on the local spectral statistics of the GUE, but depends more on the global statistics via its Stieltjes transform (Green function). Under rather mild conditions for the Pólya ensemble, we prove formulas for the hard edge kernel of the singular value statistics of the Pólya ensemble alone and the product matrix to highlight their very close similarity. Due to these observations, we even propose a conjecture for the hard edge statistics of a multiplicative Pólya ensemble on the complex matrices and a polynomial ensemble on the Hermitian matrices.

description: We report photometric and radial velocity observations of the XO-4 transiting planetary system, conducted with the FLWO 1.2m telescope and the 8.2m Subaru Telescope. Based on the new light curves, the refined transit ephemeris of XO-4b is $P = 4.1250828 \pm 0.0000040$ days and $T_c [BJD_TDB] = 2454485.93323 \pm 0.00039$. We measured the Rossiter-McLaughlin effect of XO-4b and estimated the sky-projected angle between the stellar spin axis and the planetary orbital axis to be $λ= -46.7^{\circ} ^{+8.1^{\circ}}_{-6.1^{\circ}}$. This measurement of $λ$ is less robust than in some other cases because the impact parameter of the transit is small, causing a strong degeneracy between $λ$ and the projected stellar rotational velocity. Nevertheless, our finding of a spin-orbit misalignment suggests that the migration process for XO-4b involved few-body dynamics rather than interaction with a gaseous disk. In addition, our result conforms with the pattern reported by Winn et al. (2010, ApJL, 718, L145) that high obliquities are preferentially found for stars with effective temperatures hotter than 6250~K.

description: The paper describes a method to understand time required to vaccinate against viruses in total as well as subpopulations. As a demonstration, a model based estimate for time required to vaccinate H1N1 in India, given its administrative difficulties is provided. We have proved novel theorems for the time functions defined in the paper. Such results are useful in planning for future epidemics. The number of days required to vaccinate entire high risk population in three subpopulations (villages, tehsils and towns) are noted to be 84, 89 and 88 respectively. There exists state wise disparities in the health infrastructure and capacities to deliver vaccines and hence national estimates need to be re-evaluated based on individual performances in the states.

Becoming a teacher does not come that easily : Aristotle, Confucius and education
Creators: name: Ma, Ying
Publisher: name: University of British Columbia
Year: 2018

description: One of my earliest memories was peering through my mother’s classroom window to watch her teach mathematics to middle school students. My mother inspired me to become a teacher and I believed that I had succeeded when I was appointed as a teacher and subsequently won district and national awards in China for teaching excellence. However, I found my “successes” unfulfilling: I felt more and more like a commander training her students for the battlefield of examinations where some would succeed and many would fall. I wondered why my mother had thrived while I floundered. My search for answers took me from Beijing to Vancouver for graduate study and the realization that I was actually searching for my practical identity, that is, an identity “under which you value yourself, a description under which you find your life to be worth living and your actions to be worth undertaking” (Korsgaard, 1992, p. 83) with associated ideals, roles and excellences (Lear, 2006). Searching for a practical identity is fundamentally a normative quest for ethical integrity; unfortunately the language currently available to describe teaching emphasizes teachers’ accountability for improving student test scores and assumes that higher scores indicate better preparation of the young for future jobs—the primary purpose of schooling. My search for a suitable ethical framework to understand what it meant to be a teacher quickly led to two of the most influential approaches in human history: Aristotle’s and Confucius’. I use their ideas about how to cultivate human virtue to create a dialogic interpretation of teaching that includes concern for educational purpose (eudaimonia and dao), teacher excellence and teacher-student relationships (phronesis, philia and ren) and teaching skill (techne and liuyi), continually testing my interpretations against my own experiences as student/teacher/daughter of a teacher/mother of a student. Despite my efforts, however, my thesis remains haunted by the sense of a whole without completeness, a conception of the good without closure and an aspiration without achievement—an aporia that, following Kierkegaard (1854) and Lear (2011), I now understand as the inevitable irony of any quest for ethical closure.

Constructing a virtual two-qubit gate by sampling single-qubit operations

Year: 2019

description: We show a certain kind of non-local operations can be simulated by sampling a set of local operations with a quasi-probability distribution when the task of a quantum circuit is to evaluate an expectation value of observables. Utilizing the result, we describe a strategy to decompose a two-qubit gate to a sequence of single-qubit operations. Required operations are projective measurement of a qubit in Pauli basis, and $π/2$ rotation around x, y, and z axes. The required number of sampling to get an expectation value of a target observable within an error of $ε$ is roughly $O(9^k/ε^2)$, where $k$ is the number of "cuts" performed. The proposed technique enables to perform "virtual" gates between a distant pair of qubits, where there is no direct interaction and thus a number of swap gates are inevitable otherwise. It can also be utilized to improve the simulation of a large quantum computer with a small-sized quantum device, which is an idea put forward by [Peng, et al., arXiv:1904.00102]. This work can enhance the connectivity of qubits on near-term, noisy quantum computers.

Skoruppa and the classification of maximal subgroups of PGSp(4,p) we show that its image is as large as possible. This gives a realization of PGSp(4,7) as a Galois group over $\Q$ and the corresponding number field provides a non-solvable extension of $\Q$ which ramifies only at 7.

description: Using a home-built Ku band ESR spectrometer equipped with an arbitrary waveform generator and a stripline resonator, we implement two types of pulses that would benefit quantum computers: BB1 composite pulse and a microwave frequency comb. Broadband type 1 (BB1) composite pulse is commonly used to combat systematic errors but previous experiments were carried out only on extremely narrow linewidth samples. Using a sample with a linewidth of 9.35 MHz, we demonstrate that BB1 composite pulse is still effective against pulse length errors at a Rabi frequency of 38.46 MHz. The fast control is realized with low microwave power which is required for initialization of electron spin qubits at 0.6 T. We also digitally design and implement a microwave frequency comb to excite multiple spin packets of a different sample. Using this pulse, we demonstrate coherent and well resolved excitations spanning over the entire spectrum of the sample (ranging from -20 to 20 MHz). In anticipation of scaling up to a system with large number of qubits, this approach provides an efficient technique to selectively and simultaneously control multiple qubits defined in the frequency-domain.

Improvement of the proportionality and better energy resolution was observed on lowering the temperature. This effect suggests that the already outstanding energy resolution of LaBr3:Ce can be improved even further. It also may provide new clues to better understand the processes that cause nonproportionality of inorganic scintillator response.

description: We consider a variant of random walks on finite groups. At each step, we choose an element from a set of generators ("directions") uniformly, and an integer from a power law ("speed") distribution associated with the chosen direction. We show that if the finite group is nilpotent, the mixing time of this walk is of the same order of magnitude as the diameter of a suitable pseudo-metric, D(S, a), on the group, which depends only on the generators and speeds. Additionally, we give sharp bounds on the $\ell^2$-distance between the distribution of the position of the walker and the stationary distribution, and compute D(S,a) for some examples.

description: We report the measurement of the spin-orbit angle of the extra-solar planets HAT-P-8 b, HAT-P-9 b, HAT-P-16 b and HAT-P-23 b, thanks to spectroscopic observations performed at the Observatoire de Haute-Provence with the SOPHIE spectrograph on the 1.93-m telescope. Radial velocity measurements of the Rossiter-McLaughlin effect show the detection of an apparent prograde, aligned orbit for all systems. The projected spin-orbit angles are found to be lambda=-17 deg (+9.2,-11.5), -16 deg (8), -10 deg (16), +15 deg (22) for HAT-P-8, HAT-P-9, HAT-P-16 and HAT-P-23 respectively, with corresponding projected rotational velocities of 14.5 (0.8), 12.5 (1.8), 3.9 (0.8), and 7.8 (1.6) km/s. These new results increase to 37 the number of accurately measured spin-orbit angles in transiting extrasolar systems. We conclude by drawing a tentative picture of the global behaviour of orbital alignement, involving the complexity and diversity of possible mechanisms.

Development of trajectory-based techniques for the stereotactic volumetric modulated arc therapy of cranial lesions
Creators: name: Wilson, Byron
Publisher: name: University of British Columbia
Year: 2018

description: Introduction: Stereotactic Radiosurgery is the delivery of a large, highly focused radiation dose to well defined targets. This thesis explores linac-based inverse planning algorithms that can be implemented to improve the dosimetric and delivery performance of volumetric modulated arc therapy treatments for these indications. Methods: In this work, algorithms for couch-gantry and collimator-gantry trajectory optimization were developed. Treatment plans calculated with these algorithms were compared dosimetrically to conventional methods used for treatment planning. Additionally, the clinical feasibility of the methods developed were tested by performing end-to-end patient-specific quality assurance on prospective treatments and by developing machine specific quality assurance for the intra-treatment movement of the couch and collimator. Results: This thesis introduces a robust method for optimizing the trajectory of the couch by delivering treatments along patient generalized trajectories. These treatments were able to dosimetrically outperform dynamic conformal arcs, and had higher delivery efficiency than multi-arc volumetric modulated arc therapy. Similarly, collimator trajectory optimization was shown to reduce the dose bath when compared with the clinical standard of care. These methods were shown to be safe for delivery using phantom verification studies. Conclusion: This thesis outlines methods for stereotactic radiosurgery which show dosimetric improvement over previous methodology and are clinically feasible.

description: In a vertex algebra setting, we consider non-local screening operators associated to the basis of any non-integral lattice. We have previously shown that, under certain restrictions, these screening operators satisfy the relations of a quantum shuffle algebra or Nichols algebra associated to a diagonal braiding, which encodes the non-locality and non-integrality. In the present article, we take all finite-dimensional diagonal Nichols algebras, as classified by Heckenberger, and find all lattice realizations of the braiding that are compatible with reflections. Usually, the realizations are unique or come as one- or two-parameter families. Examples include realizations of Lie superalgebras. We then study the associated algebra of screenings with improved methods. Typically, for positive definite lattices we obtain the Nichols algebra, such as the positive part of the quantum group, and for negative definite lattices we obtain a certain extension of the Nichols algebra generalizing the infinite quantum group with a large center.

description: Accurate information on long-term variations in solar irradiance, important for understanding the solar influence on Earth's climate, cannot be derived from direct irradiance measurements due to the comparatively short lifetimes of space-borne experiments. Models using measurements of the solar photospheric magnetic field as input can provide an independent assessment of the changes. The SATIRE-S model does just that. Unfortunately, the magnetogram archives used by SATIRE-S to recover irradiance variations are also relatively short-lived and have short mutual overlapping periods, making it difficult to evaluate their consistency. We improve SATIRE-S total solar irradiance (TSI) reconstruction by firstly incorporating magnetograms from the Mt Wilson Observatory as well as unsigned magnetograms reconstructed from Meudon, Rome, and San Fernando Ca II K data, and secondly, by re-analysing all periods of overlaps between the various archives. Our combined daily irradiance reconstruction from all eight input archives returns an excellent agreement with direct measurements of irradiance, in particular we find a correlation coefficient of 0.98 when comparing to TSIS1/TIM (Total and Spectral Solar Irradiance Sensor Total Irradiance Monitor) data. The minimum-to-minimum TSI difference between 1976 and 2019 is -0.2$\pm0.17$~Wm$^{-2}$, while the TSI difference between the 1986 and 2019 minima is statistically insignificant (-0.06$\pm0.13$~Wm$^{-2}$). Our analysis also sheds light on the trend shown by the TSI over the so-called ACRIM gap, disfavouring a hypothesised increasing trend in TSI in that period. By including more direct and indirect magnetogram time series, we have made the TSI reconstructed by SATIRE-S more robust and accurate. The new series shows a reduced trend of decreasing TSI over the last half century, which agrees well with most composites of measured TSI.

description: In order to extend the experimental database relevant for the astrophysical gamma-process towards the unexplored heavier mass region, the cross sections of the 151Eu(alpha,gamma)155Tb and 151Eu(alpha,n)154Tb reactions have been measured at low energies between 12 and 17 MeV using the activation technique. The results are compared with the predictions of statistical model calculations and it is found that the calculations overestimate the cross sections by about a factor of two. A sensitivity analysis shows that this discrepancy is caused by the inadequate description of the alpha+nucleus channel. A factor of two reduction of the reaction rate of 151Eu(alpha,gamma)155Tb in gamma-process network calculations with respect to theoretical rates using the optical potential by McFadden and Satchler (1966) is recommended.

description: We employ so-called quantum kernel estimation to exploit complex quantum dynamics of solid-state nuclear magnetic resonance for machine learning. We propose to map an input to a feature space by input-dependent Hamiltonian evolution, and the kernel is estimated by the interference of the evolution. Simple machine learning tasks, namely one-dimensional regression tasks and two-dimensional classification tasks, are performed using proton spins which exhibit correlation over 10 spins. We also performed numerical simulations to evaluate the performance without the noise inevitable in the actual experiments. The performance of the trained model tends to increase with the longer evolution time, or equivalently, with a larger number of spins involved in the dynamics for certain tasks. This work presents a quantum machine learning experiment using one of the largest quantum systems to date.
Prolonged Mild-to-Moderate Hypothermia for Refractory Intracranial Hypertension

Year: 2023

description: Therapeutic hypothermia is an emerging therapy for brain injury and cerebral edema. Hypothermia is known to reduce death and neurologic morbidity in survivors of cardiac arrest from ventricular fibrillation. Traumatic brain injury (TBI) trials studies of short-term hypothermia (24 to 48hours) have had conflicting results. Recent evidence however suggests prolonged hypothermia (48 hours to 14 days) may be beneficial for TBI and select cases of nontraumatic brain injury especially when the duration of cerebral edema and intracranial hypertension is expected to last longer than 24 hours.

description: We investigate the effect of induced massive radiation given off during the time of collapse of a massive spherically symmetric domain wall in the context of the functional Schrödinger formalism. Here we find that the introduction of mass suppresses the occupation number in the infrared regime of the induced radiation during the collapse. The suppression factor is found to be given by $e^{-βm}$, which is in agreement with the expected Planckian distribution of induced radiation. Thus a massive collapsing domain wall will radiate mostly (if not exclusively) massless scalar fields, making it difficult for the domain wall to shed any global quantum numbers and evaporate before the horizon is formed.

description: Am 7.5.1958 hielt der einst gefeierte und heute weitgehend vergessene
Regisseur und Schriftsteller Ludwig Berger in der Hamburger Musikhalle
eine Gedenkrede im Rahmen der „Brahms-Festwoche“ anlässlich des
125. Geburtstages von Johannes Brahms. Bergers rund 60 Minuten lange
Ansprache wurde mitgeschnitten und in kleiner Auflage von der
Hamburger Schallplattenfirma Teldec als Langspielplatte vertrieben
sowie mehrfach im Druck veröffentlicht, zunächst vom Senat der
Hansestadt, dann vom Tübinger Wunderlich–Verlag. Dass hier ein
deutscher Kulturschaffender jüdischer Herkunft von der Hamburger
Kulturbehörde als Festredner eingeladen wurde, mag mit dem Bestreben
zu tun gehabt haben, sich von dem 25 Jahre zuvor, im Mai 1933 zum
100-jährigen Jubiläum abgehaltenen „Reichs-Brahmsfest“
abzugrenzen. Obschon bereits seit 1931 in der Planung, waren diese
Feierlichkeiten zumindest teilweise für die „völkischen“ Zwecke
des kurz zuvor installierten Nazi-Regimes vereinnahmt worden.

Im Umfeld des „Reichs-Brahmsfests“ von 1933 waren Gerüchte
aufgetaucht, der Hamburger Komponist sei jüdischer Abstammung (der
Familienname leite sich angeblich aus „Abrahamson“ her). Peri
Arndt, Das Gerücht über Brahms’ jüdische Abstammung, in:
Arbeitsgruppe Exilmusik am Musikwissenschaftlichen Institut der
Universität Hamburg (Hrsg.), Das „Reichs-Brahmsfest“ 1933 in
Hamburg. Rekonstruktion und Dokumentation, Hamburg 1997, S. 119–120.
Es ist nicht klar, ob Berger von diesen Gerüchten wusste,
interessanterweise setzte er sich in seiner Festrede aber ebenfalls
mit der Herkunft des Nachnamens Brahms auseinander.
