description: We study the topological types of pants decompositions of a surface by associating to any pants decomposition $P,$ in a natural way its pants decomposition graph, $Γ(P).$ This perspective provides a convenient way to analyze the maximum distance in the pants complex of any pants decomposition to a pants decomposition containing a non-trivial separating curve for all surfaces of finite type. In the main theorem we provide an asymptotically sharp approximation of this non-trivial distance in terms of the topology of the surface. In particular, for closed surfaces of genus $g$ we show the maximum distance in the pants complex of any pants decomposition to a pants decomposition containing a separating curve grows asymptotically like the function $\log(g).$

description: We consider decomposition of coordinate independent states into SO(9)xSU(2) representations in SU(2) Matrix theory. To see what and how many representations appear in the decomposition, we compute the character, which is given by a trace over the coordinate independent states, and decompose it into the sum of products of SO(9) and SU(2) characters.

Language socialization in the post-colonial Korean diaspora in Japan : language ideologies, identities, and language maintenance
Creators: name: Son, Jeonghye
Publisher: name: University of British Columbia
Year: 2017

description: This ethnographic research investigates Korean language socialization within the Korean resident (Zainichi Korean) community in Japan, particularly focusing on the community connected to Chongryun (pro-North Korean organization) schools. That is, this study seeks to find (1) how Korean children in the community of Chongryun schools are socialized to learn and use Korean and (2) how they are socialized through language to culturally significant values, beliefs, and identities that affect their Korean development. To this end, I collected data through participant observation in a Chongryun middle school and school-related events, audio and video-recorded family interactions, and interviews with schoolteachers, students, and parents. The study results show that the younger generation in this community were exposed and socialized into multiple language ideologies that linked the Korean language not only to Korean identity and the space of school, but also to morality (e.g., a good student, patriot), politeness, the status of Chongryun school students, and foreignness/outcast through participating in a variety of interactional practices. Also, in this study I paid attention to the agency of Chongryun school students and found that their socialization outcomes were partial, selective, and situational. In other words, not only did they play a part in reproducing and reinforcing the existing ideologies of language and ethnic boundaries (i.e., Japanese vs. Koreans) but they also contributed to redefining the relationship between the Korean language and Korean identity and reorganizing the evaluative order of Korean varieties. Lastly, I argue that the sociocultural phenomena engendered by globalization (e.g., Korean Wave and power of English) motivated some students to further improve their Korean proficiency on the one hand, but on the other hand, they demotivated others in continuing to study and maintain their Korean abilities in the future.

description: We investigate the robustness of the microscopic reversibility in open quantum systems which is discussed by Monnai [arXiv:1106.1982 (2011)]. We derive an exact relation between the forward transition probability and the reversed transition probability in the case of a general measurement basis. We show that the microscopic reversibility acquires some corrections in general and discuss the physical meaning of the corrections. Under certain processes, some of the correction terms vanish and we numerically confirmed that the remaining correction term becomes negligible; the microscopic reversibility almost holds even when the local system cannot be regarded as macroscopic.

description: Using the AdS/CFT correspondence, we probe the scale-dependence of thermalization in strongly coupled field theories following a quench via saddlepoint calculations of 2-point functions, Wilson loops and entanglement entropy in $d=2,3,4$. For homogeneous initial conditions, the entanglement entropy thermalizes slowest, and sets a timescale for equilibration that saturates a causality bound. The growth rate of entanglement entropy density is nearly volume-independent for small volumes, but slows for larger volumes. In this strongly coupled setting, the UV thermalizes first.

description: We present the results of two-dimensional and three-dimensional magnetohydrodynamical numerical simulations of relativistic magnetic reconnection, with particular emphasis on the dynamics of the plasma in a Petschek-type configuration with high Lundquist numbers, S\sim 10^5-10^8. The numerical scheme adopted, allowing for unprecedented accuracy for this type of calculations, is based on high order finite volume and discontinuous Galerkin methods as recently proposed by \citet{Dumbser2009}. The possibility of producing high Lorentz factors is discussed, showing that Lorentz factors close to \sim 4 can be produced for a plasma parameter σ_m=20. Moreover, we find that the Sweet-Parker layers are unstable, generating secondary magnetic islands, but only for S > S_c = 10^8, much larger than what is reported in the Newtonian regime. Finally, the effects of a mildly anisotropic Ohm law are considered in a configuration with a guide magnetic field. Such effects produce only slightly faster reconnection rates and Lorentz factors of about 1% larger with respect to the perfectly isotropic Ohm law.

description: The Lagrangian describing the bulk electromagnetic response of a three-dimensional strong topological insulator contains a topological `axion' term of the form 'θE dot B'. It is often stated (without proof) that the corresponding action is quantized on periodic space-time and therefore invariant under 'θ-> θ+2π'. Here we provide a simple, physically motivated proof of the axion action quantization on the periodic space-time, assuming only that the vector potential is consistent with single-valuedness of the electron wavefunctions in the underlying insulator.

description: We have studied the reflectivity of CMOS-compatible three-dimensional silicon inverse woodpile photonic crystals at near-infrared frequencies. Polarization-resolved reflectivity spectra were obtained from two orthogonal crystal surfaces corresponding to 1.88 pi sr solid angle. The spectra reveal broad peaks with high reflectivity up to 67 % that are independent of the spatial position on the crystals. The spectrally overlapping reflectivity peaks for all directions and polarizations form the signature of a broad photonic band gap with a relative bandwidth up to 16 %. This signature is supported with stopgaps in plane wave bandstructure calculations and with the frequency region of the expected band gap.

Hard dihadron correlations in heavy-ion collisions at RHIC and LHC

description: High transverse momentum (P_T) processes are considered to be an important tool to probe and understand the medium produced in ultrarelativistic heavy-ion collisions via the interaction of hard, perturbatively produced partons with the medium. In this context, triggered hard dihadron correlations constitute a class of observables set between hard single inclusive hadrons (dominated by the leading jet fragments) and fully reconstructed jets - while they probe some features of the perturbative QCD evolution of a parton shower in the medium, they do not suffer from the problem of finding a suitable separation between soft perturbative (jet-like) and soft non-perturbative (medium-like) physics as the identification of full jets does. On the other hand, the trigger requirement introduces non-trivial complications to the process, which makes the medium-modification of the correlation pattern difficult and non-intuitive to understand. In this work, we review the basic physics underlying triggered dihadron correlations and make a systematic comparison of several combinations of medium evolution and parton-medium interaction models with the available data from 200 AGeV Au-Au collisions at RHIC. We also discuss the expected results for 2.76 ATeV Pb-Pb collisions at the LHC.

title: Predicting psychological safety: the moderating role of gender congruence
Creators: name: Askari, Ana
Publisher: name: Memorial University of Newfoundland

publisherIdentifierScheme: ROR
Year: 2024

description: Psychological safety was initially introduced as a concept approximately six decades ago. The research in this area experienced a renaissance in the 1990’s—a boom motivated by recognizing the challenge of navigating uncertainty and the changing nature of organizations. Today, theoretical and practical significance of psychological safety is amplified by the increasingly complex and interdependent nature of the work in organizations across industries. Using data collected by Mental Health Research Canada as part of their 2021 Guarding Minds at Work survey, a final sample of 1539 participants demonstrated that support from one’s supervisor and respect from one’s peers contribute positively to perceptions of psychological safety. Furthermore, it was hypothesized that these relationships would be moderated by gender congruence of the industry such that the relationships would be stronger for individuals in gender-incongruent industries. This hypothesis was found to be partially supported, indicating that the relationship between supervisor support and psychological safety was strongest for women who work in male-dominated industries. The study's limitations and implications for research and practitioners are discussed. Keywords: psychological safety, supervisor support, perceived civility climate, gender congruence, male-dominated industries, female-dominated industries.

description: We present a theoretical proposal for the implementation of geometric quantum computing based on a Hamiltonian which has a doubly degenerate ground state. Thus the system which is steered adiabatically, remains in the ground-state. The proposed physical implementation relies on a superconducting circuit composed of three SQUIDs and two superconducting islands with the charge states encoding the logical states. We obtain a universal set of single-qubit gates and implement a non-trivial two-qubit gate exploiting the mutual inductance between two neighboring circuits, allowing us to realize a fully geometric ground-state quantum computing. The introduced paradigm for the implementation of geometric quantum computing is expected to be robust against environmental effects.

Oxidative cyclization of phenolic N-acyl sulfonamides
Creators: name: Wang, Xueqing
Publisher: name: University of British Columbia
Year: 2017

description: The oxidative activation of appropriately substituted phenols with a hypervalent iodine reagent, in the presence of suitable nitrogen nucleophiles, results in formation of 2- or 4-amidodienones. The process is described as the oxidative amidation of phenols. The dienones thus produced are useful building blocks for the synthesis of alkaloids. The nitrogen nucleophile may be an oxazoline, a sulfonamide or phosphoramide (intramolecular reactions), or a nitrile (bimolecular reaction), but not a carboxamide. This is because carboxamides express Onucleophilicity toward oxidatively activated phenols, resulting in formation of iminolactones, which are readily hydrolyzed to lactones upon workup. This present thesis describes efforts to extend oxidative amidation chemistry to carboxamides. The behavior of phenolic N-acyl sulfonamides was thus explored. The product obtained upon oxidative cyclization of these substrates proved to be dependent upon their structure. In many cases, N-sulfonyl iminolactones were thus obtained. These heretofore undocumented products proved to be surprisingly stable and resistant to hydrolysis.

description: We describe a mechanism for a controlled generation of a pure Bell state with correlated atoms that involve two or zero excitations. The mechanism inhibits transitions into singly excited collective states of a two-atom system by shifting them from their unperturbed energies. The shift is accomplished by the dipole-dipole interaction between the atoms. The creation of the Bell state is found to be dependent on the relaxation of the atomic excitation. When the relaxation is not present or can be ignored, the state of the system evolves harmonically between a separable to the maximally entangled state. We follow the temporal evolution of the state and find that the concurrence can be different from zero only in the presence of the dipole-dipole interaction. Furthermore, in the limit of a large dipole-dipole interaction, the concurrence reduces to that predicted for an X-state of the system. A general inequality is found which shows that the concurrence of an X-state system is a lower bound for the concurrence of the two-atom system. With the relaxation present, the general state of the system is a mixed state that under a strong dipole-dipole interaction reduces the system to an X-state form. We find that mixed states admit of lower level of entanglement, and the entanglement may occur over a finite range of time. A simple analytical expression is obtained for the steady-state concurrence which shows that there is a threshold value for the dipole-dipole interaction relative to the Rabi frequency of the driving field above which the atoms can be entangled over the entire time of the evolution.

We show that the Drell-Yan production and the decays of new exotic Sigma leptons are testable at the LHC. Their production is abundant due to nontrivial electroweak gauge charges. For 1 fb^-1 of integrated luminosity at the present LHC sqrt{s}=7 TeV, there can be 270 Sigma-Sigmabar pairs produced for M_Sigma = 400 GeV. Besides producing same-sign dilepton events, they could lead, due to a chosen small mixing between heavy and light leptons, to ~10 golden decays Sigma^{+++}(Sigma^{+++}-bar) --> W^\pm W^\pm l^\pm with a specific decay signature.

description: Monte Carlo (MC) simulations are the standard tool for describing jet-like multi-particle final states. To apply them to the simulation of medium-modified jets in heavy ion collisions, a probabilistic implementation of medium-induced quantum interference effects is needed. Here, we analyze in detail how the quantum interference effects included in the BDMPS-Z formalism of medium-induced gluon radiation can be implemented in a quantitatively controlled, local probabilistic parton cascade. The resulting MC algorithm is formulated in terms of elastic and inelastic mean free paths, and it is by construction insensitive to the IR and UV divergences of the total elastic and inelastic cross sections that serve as its basic building blocks in the incoherent limit. Interference effects are implemented by reweighting gluon production histories as a function of the number of scattering centers that act within the gluon formation time. Unlike existing implementations based on gluon formation time, we find generic arguments for why a quantitative implementation of quantum interference cannot amount to a mere dead-time requirement for subsequent gluon production. We validate the proposed MC algorithm by comparing MC simulations with parametric dependencies and analytical results of the BDMPS-Z formalism. In particular, we show that the MC algorithm interpolates correctly between analytically known limiting cases for totally coherent and incoherent gluon production, and that it accounts quantitatively for the medium-induced gluon energy distribution and the resulting average parton energy loss. We also verify that the MC algorithm implements the transverse momentum broadening of the BDMPS-Z formalism. We finally discuss why the proposed MC algorithm provides a suitable starting point for going beyond the approximations of the BDMPS-Z formalism.

Decision support for emergency response in interdependent infrastructure systems
Creators: name: Alutaibi, Khaled
Publisher: name: University of British Columbia
Year: 2017

description: In recent years, extreme events, such as hurricanes, earthquakes, floods and fires, occur more frequently and at a higher intensity. The growing complexity and interdependence of modern infrastructure systems makes them vulnerable to such events. Emergency response is the process of implementing appropriate actions to reduce human and economic losses following these events. Efficient response requires an understanding of the existing infrastructure systems and their interdependencies. In this thesis, we propose a decision support system for helping emergency responders in making efficient decisions during extreme events. Fires are chosen as an example of the extreme events and firefighting operations as the emergency response to these events. Everyday, fire managers are faced with making increasingly complex manpower decisions; trying to minimize costs and risk levels. The effectiveness of firefighting operations is crucial in minimizing both cost of suppression and economic losses. The contributions of this thesis focus on two levels of fire management plans: operational and strategic. We first develop a methodology to optimize the allocation process of firefighting resources in multiple-fire incidents. The developed methodology employs reinforcement learning, a machine learning algorithm that optimizes the allocation of firefighting units to minimize the total economic losses in the long run. To consider the concept of infrastructure interdependencies in evaluating the economic impact of the incidents, we model a large petrochemical complex using the Infrastructure Interdependency Simulator (i2Sim). In addition, a capacity planning methodology is developed to investigate the impact of manpower investment on the effectiveness of firefighting operations. The developed methodology aims at finding the optimal number of firefighters to be recruited to contain fires and effectively extinguish them. It performs an economic analysis to evaluate the efficiency fire management plans. Finally, we propose a methodology to evaluate the effectiveness of emergency response plans in improving infrastructure resilience. This methodology focuses on two dimensions of resilience: resourcefulness and rapidity. These dimensions are measured by the optimality of allocating firefighting units and by minimizing economic losses. The proposed methodologies are tested using a case study of a large petrochemical complex and promising results are achieved.

description: We present an unquenched $N_f=2$ lattice computation of the $B_{K}$ parameter which controls $K^0-\bar K^0$ oscillations. A partially quenched setup is employed with two maximally twisted dynamical (sea) light Wilson quarks, and valence quarks of both the maximally twisted and the Osterwalder--Seiler variety. Suitable combinations of these two kinds of valence quarks lead to a lattice definition of the $B_{K}$ parameter which is both multiplicatively renormalizable and O($a$) improved. Employing the non-perturbative RI-MOM scheme, in the continuum limit and at the physical value of the pion mass we get $B^{\rm RGI}_K=0.729\pm 0.030$, a number well in line with the existing quenched and unquenched determinations.

Photons and Baryons before Atoms: Improving the Tight-Coupling Approximation

description: Prior to recombination photons, electrons, and atomic nuclei rapidly scattered and behaved, almost, like a single tightly-coupled photon-baryon plasma. We investigate here the accuracy of the tight-coupling approximation commonly used to numerically evolve the baryon and photon perturbation equations at early times. By solving the exact perturbations equations with a stiff solver starting deep in the radiation-dominated epoch we find the level of inaccuracy introduced by resorting to the standard first-order tight-coupling approximation. We develop a new second-order approximation in the inverse Thomson opacity expansion and show that it closely tracks the full solution, at essentially no extra numerical cost. We find the bias on estimates of cosmological parameters introduced by the first-order approximation is, for most parameters, negligible. Finally, we show that our second-order approximation can be used to reduce the time needed to compute cosmic microwave background angular spectra by as much as ~17%.

Safety diagnosis of vehicle-bicycle interactions using computer vision systems : a case study in Vancouver, B.C.
Creators: name: Puscar, Federico Martin
Publisher: name: University of British Columbia

description: Active road users such as cyclists are usually subject to an elevated risk of collision. Therefore, there is a need for efficient techniques for evaluating the safety of active road users. Traditional road safety analysis has often been conducted using historical collision records. However, limitations associated with collision data have motivated the development of complementary proactive techniques for road safety analysis. Recently, there has been significant interest in using traffic conflicts to analyze safety which has been strengthened by the availability of automated traffic conflict analysis tools. This thesis demonstrates two applications of automated road safety analysis techniques using traffic conflicts. The first application is a safety diagnosis of a major intersection in Vancouver, British Columbia, with bicycle and pedestrian safety issues. Automated video-based computer vision techniques are used to extract and analyze data from the video footage. Traffic conflict indicators, such as time to collision and post-encroachment time, are used to assess conflicts along the intersection to identify safety problems based on the frequency and severity of conflicts. Different spatial and temporal non-conforming behavior patterns are also analyzed. The diagnosis revealed that the Burrard Bridge’s access and exit ramps are the main sources of conflicts at the intersection and their design encouraged many non-conforming behavior patterns. It can be expected that removing both ramps will address a significant amount of safety problems. The second application covers detailed analysis of cyclist yielding behavior at the same intersection. Cyclist yielding behavior is evaluated by analyzing vehicle and bicycle yielding rates in two bicycle crossings with different rules of priority. Compliance with traffic regulations is also studied by looking at how intersections actually operate in contrast to the formal traffic rules. Results showed that bicycle yielding rates can change significantly depending on the crossing’s configuration and legal right-of-way. Low bicycle yielding rates in combination with consistent but relatively low vehicle yielding rates can present a safety problem: understanding cyclist yielding behavior can enable engineers to design and build safer intersections which are consistent with road users’ expectations, and to develop more realistic models of traffic behavior, safety, and operations.

description: Time-resolved electron dynamics in coupled quantum dots is directly observed by a pulsed-gate technique. While individual gate voltages are modulated with periodic pulse trains, average charge occupations are measured with a nearby quantum point contact as detector. A key component of our setup is a sample holder optimized for broadband radio frequency applications. Our setup can detect displacements of single electrons on time scales well below a nanosecond. Tunneling rates through individual barriers and relaxation times are obtained by using a rate equation model. We demonstrate the full characterization of a tunable double quantum dot using this technique, which could also be used for coherent charge qubit control.
What can(not) be measured with ton-scale dark matter direct detection experiments

description: Direct searches for dark matter have prompted in recent years a great deal of excitement within the astroparticle physics community, but the compatibility between signal claims and null results of different experiments is far from being a settled issue. In this context, we study here the prospects for constraining the dark matter parameter space with the next generation of ton-scale detectors. Using realistic experimental capabilities for a wide range of targets (including fluorine, sodium, argon, germanium, iodine and xenon), the role of target complementarity is analysed in detail while including the impact of astrophysical uncertainties in a self-consistent manner. We show explicitly that a multi-target signal in future direct detection facilities can determine the sign of the ratio of scalar couplings $f_n/f_p$, but not its scale. This implies that the scalar-proton cross-section is left essentially unconstrained if the assumption $f_p\sim f_n$ is relaxed. Instead, we find that both the axial-proton cross-section and the ratio of axial couplings $a_n/a_p$ can be measured with fair accuracy if multi-ton instruments using sodium and iodine will eventually come online. Moreover, it turns out that future direct detection data can easily discriminate between elastic and inelastic scatterings. Finally, we argue that, with weak assumptions regarding the WIMP couplings and the astrophysics, only the dark matter mass and the inelastic parameter (i.e. mass splitting) may be inferred from the recoil spectra -- specifically, we anticipate an accuracy of tens of GeV (tens of keV) in the measurement of the dark matter mass (inelastic parameter).

description: We theoretically investigate schemes to discriminate between two nonorthogonal quantum states given multiple copies. We consider a number of state discrimination schemes as applied to nonorthogonal, mixed states of a qubit. In particular, we examine the difference that local and global optimization of local measurements makes to the probability of obtaining an erroneous result, in the regime of finite numbers of copies $N$, and in the asymptotic limit as $N \rightarrow \infty$. Five schemes are considered: optimal collective measurements over all copies, locally optimal local measurements in a fixed single-qubit measurement basis, globally optimal fixed local measurements, locally optimal adaptive local measurements, and globally optimal adaptive local measurements. Here, adaptive measurements are those for which the measurement basis can depend on prior measurement results. For each of these measurement schemes we determine the probability of error (for finite $N$) and scaling of this error in the asymptotic limit. In the asymptotic limit, adaptive schemes have no advantage over the optimal fixed local scheme, and except for states with less than 2% mixture, the most naive scheme (locally optimal fixed local measurements) is as good as any noncollective scheme. For finite $N$, however, the most sophisticated local scheme (globally optimal adaptive local measurements) is better than any other noncollective scheme, for any degree of mixture.

description: In this paper we give a frame for application of the averaging method to Bose-Einstein condensates (BECs) and obtain an abstract result upon the dynamics of BECs. Using aver- aging method, we determine the location where the modulated amplitude waves (periodic or quasi-periodic) exist and we also study the stability and instability of modulated amplitude waves (periodic or quasi-periodic). Compared with the previous work, modulated amplitude waves studied in this paper have nontrivial phases and this makes the problem become more diffcult, since it involves some singularities.
